Description

Network identifier display method, device and system

Technical Field

The present invention relates to the field of mobile communications technologies, and in particular, to a method, an apparatus, and a system for displaying a network identifier.

Background

With the development of fifth generation mobile communication (5th generation mobile networks,5G) technology, the third generation partnership project (3rd generation partnership project,3GPP) has promulgated two 5G standards, independent (SA) networking and non-independent (NSA) networking for deployment of 5G networks.

Because of small investment and quick networking, the NSA networking mode relying on a long term evolution (long term evolution, LTE) network is a current research hotspot. NSA networking employs multi-mode dual connectivity (multi rat dual connectivity, MR-DC) to deploy the network. The dual connection means that a User Equipment (UE) connects an LTE access network (radio access network, RAN) device and a 5G access network device simultaneously, wherein one access network device is a primary node, the other access network device is a secondary node, and the UE establishes connection with the same core network through the primary node and the secondary node, respectively.

Typically, the UE may display network identifiers of the currently available networks on the display screen, so as to prompt the user for the currently available networks. Under dual connectivity in NSA networking, how the UE prompts the user for the networks currently available is a current research hotspot.

Disclosure of Invention

The embodiment of the application provides a method, equipment and a system for displaying network identifications. The terminal can display the network identification of the 4G network and the network identification of the 5G network according to the connection conditions with the 4G network and the 5G network respectively, and the display of the two network identifications is not affected. This may prompt the user terminal for the actual network conditions.

In a first aspect, an embodiment of the present application provides a method for displaying a network identifier, where the method may include: the terminal displays a first identifier and a first indicator; the terminal receives a Radio Resource Control (RRC) reconfiguration signaling sent by a first device; responsive to the RRC reconfiguration signaling, the terminal measures a signal transmitted by the second device; the terminal measures the signal sent by the second equipment; the terminal displays a second identification and a second indicator. The terminal and the first equipment are communicated through a Long Term Evolution (LTE) link, and the terminal and the second equipment are communicated through a new wireless NR link; the first device is connected with the second device; the first identifier is used for indicating that the terminal is connected to the first device or the terminal measures a signal sent by the first device, and the first indicator is used for indicating the strength of the signal sent by the first device measured by the terminal; the second identifier is used for indicating that the terminal measures the signal sent by the second device, and the second indicator is used for indicating the strength of the signal sent by the second device, which is measured by the terminal.

With reference to the first aspect, in some embodiments, the first device and the second device are both connected to a 5G core network. That is, the method of the first aspect may be applied in a terminal in a 4G and 5G dual connectivity (E-UTRA NR dual connection, EN-DC) deployed network based on the 4G core network EPC.

Implementing the method of the first aspect, the terminal displays the first identifier and the first indicator simultaneously, and if the signal sent by the second device is measured, the terminal displays the second identifier and the second indicator simultaneously. Therefore, the terminal can display the corresponding network identifier and the signal strength indicator according to the actual network condition, and feed back the actual network condition for the user, so that the user can use the service provided by the terminal according to the actual network condition, and the user experience is improved.

In combination with the first aspect, in some embodiments, both the first and second identifiers may be implemented as visual interface elements of characters, icons, text, etc. For example, the first identifier may be the character "4G", the character "LTE", etc., and the second identifier may be the character "5G", the character "NR", etc.

With reference to the first aspect, in some embodiments, the implementation form of the first indicator and the second indicator may be a signal lattice including a plurality of signal bars. The more signal bars, the stronger the signal strength indicated by the indicator.

With reference to the first aspect, in some embodiments, the terminal may receive RRC reconfiguration signaling sent by the first device when a value of a first field in the received system message is a preset value. Wherein the system message is sent by the first device; the first field having the value of the preset value is used to indicate that the first device supports the non-independent networking NSA.

With reference to the first aspect, in some embodiments, the RRC reconfiguration signaling indicates a first time and a first frequency point. The terminal may measure a signal transmitted by the second device using the first frequency point at the first time in response to the RRC reconfiguration signaling. That is, the terminal may measure a signal transmitted by the second device under the direction of the first device.

In combination with the first aspect, in some embodiments, in response to RRC reconfiguration signaling sent by the first device, when the terminal measures a signal sent by the second device, the following two cases may occur:

1. the terminal successfully measures the signal sent by the second device. In this case, the terminal may display the second identification and the second indicator. The second indicator is used for indicating a signal sent by the second device, which is measured by the terminal at the time.

2. The terminal does not successfully measure the signal sent by the second device. In this case, the terminal may measure the signal transmitted by the second device again and display the second identification and the second indicator when the signal transmitted by the second device is measured. The second indicator is used to indicate the signal sent by the second device, which is measured again by the terminal. In this way, when the terminal fails to measure the signal sent by the second device under the instruction of the RRC reconfiguration signaling, the signal sent by the second device may be measured again, so as to ensure that the terminal measures the signal sent by the second device, and is further connected to the first device and the second device.

In the case 2, when the terminal measures the signal sent by the second device again, a suitable measurement mode can be selected according to the current state of the terminal, so that the signal sent by the second device can be measured more quickly, or the power consumption can be saved in the measurement process. The following is a description of how the terminal selects a measurement mode according to the state.

When there is an RRC connection between the terminal and the first device, that is, when the terminal is in a connected state under LTE, the terminal measures a signal transmitted by the first device while measuring a signal transmitted by the second device, and/or the terminal measures a signal transmitted by the second device using a second frequency point.

When there is no RRC connection between the terminal and the first device, i.e., when the terminal is in an idle state under LTE, the terminal measures signals transmitted by the second device at all frequencies on a supported frequency band, and/or the terminal measures signals transmitted by the second device using the second frequency point.

In some embodiments, the second frequency point mentioned in the above embodiments may include one or more of the following: the terminal history resides in the frequency point of the 5G cell, the 5G frequency point specified by the operator corresponding to the terminal, the 5G frequency point corresponding to the operator to which the first device belongs, or the frequency point used when the terminal history measures the signal sent by the second device. Such a second frequency point can improve the efficiency of the terminal in measuring the signal sent by the second device.

With reference to the first aspect, in some embodiments, when the first identifier is used to indicate that the terminal measures a signal sent by the first device, the terminal may measure the signal sent by the first device before displaying the first identifier and the first indicator, and display the first identifier and the first indicator after measuring the signal sent by the first device.

With reference to the first aspect, in some embodiments, when the first identifier is used to indicate that the terminal is connected to the first device, the terminal may perform a procedure of establishing an RRC connection between the terminal and the first device before displaying the first identifier and the first indicator, and display the first identifier and the first indicator after the RRC connection is established.

With reference to the first aspect, in some embodiments, the terminal may periodically measure a signal transmitted by the second device, and update the second indicator according to the measured strength of the signal transmitted by the second device. Therefore, the actual network condition of the terminal can be prompted to the user, and the user experience is improved.

With reference to the first aspect, in some embodiments, the terminal may further stop displaying the second identifier and the second indicator when any one of: and when the terminal does not measure the signal sent by the first equipment beyond the second preset time, when the terminal receives the signaling sent by the first equipment and used for deleting the auxiliary station, or when no RRC connection exists between the terminal and the first equipment.

With reference to the first aspect, in some embodiments, the terminal may periodically measure a signal transmitted by the first device and update the first indicator according to the measured strength of the signal transmitted by the first device. Therefore, the actual network condition of the terminal can be prompted to the user, and the user experience is improved.

With reference to the first aspect, in some embodiments, the terminal may further stop displaying the first identifier and the first indicator when the signal sent by the first device is not measured for more than a second preset time period. Therefore, the actual network condition of the terminal can be prompted to the user, and the user experience is improved.

In combination with the first aspect, in some embodiments, the terminal may display the first identifier, the first indicator, the second identifier, and the second indicator in a status bar in the display screen.

In a second aspect, an embodiment of the present application provides a terminal, including: a mobile communication module, a display screen, a memory, one or more processors; the mobile communications module, the display screen, the memory are coupled with the one or more processors, the memory is for storing computer program code comprising computer instructions that are invoked by the one or more processors to cause the terminal to perform the method as in the first aspect or any implementation of the first aspect.

In a third aspect, embodiments of the present application provide a computer program product comprising instructions which, when run on a terminal, cause the terminal to perform a method as in the first aspect or any implementation of the first aspect.

In a fourth aspect, embodiments of the present application provide a computer-readable storage medium, including instructions that, when executed on a terminal, cause the terminal to perform a method as in the first aspect or any implementation manner of the first aspect.

By implementing the technical scheme provided by the embodiment of the application, the terminal can measure the signal sent by the second device according to the RRC reconfiguration signaling sent by the first device, and if the measurement fails, the terminal can measure the signal sent by the second device again. The terminal may display the network identifier and the signal strength indicator of the 5G network simultaneously when measuring the signal transmitted by the second device while displaying the network identifier and the signal strength indicator of the 4G network. That is, the terminal can display the corresponding network identifier and the signal strength indicator according to the actual network condition, so as to feed back the actual network condition for the user, and facilitate the user to use the service provided by the terminal according to the actual network condition, thereby improving the user experience.

Referring to fig. 1A, fig. 1A is a schematic architecture diagram of a communication system 10 according to an embodiment of the present application. The communication system 10 shown in fig. 1A is a 5G communication system, a New Radio (NR) system, a machine-to-machine communication (Machine to Machine, M2M) system, or the like, which is networked by NSA networking. The communication system 10 includes: terminal 100, access network (RAN), core Network (CN).

The terminal may include a smart phone (e.g., a mobile phone with an Android system or iOS system, etc.), a tablet computer, a notebook computer, a palm top computer, a mobile internet device (MID, mobile internet device), a wearable device (e.g., a smart watch, a smart bracelet, etc.), or other internet-accessible device. In the embodiments of the present application, the terminal may be referred to as a UE.

In the embodiment of the present application, the terminal 100 stores user information, and may communicate with the access network and the core network in the communication system 10 according to the user information, so as to use network services, such as a voice call service, a video service, and the like, provided by the operator corresponding to the terminal 100. Wherein the user information may include, but is not limited to: international mobile subscriber identity (international mobile subscriber identification number, IMSI), authentication and encryption information Ki, IMSI authentication algorithm, encryption key generation algorithm A5, etc. The subscriber information may be stored in a subscriber identity module (subscriber identity module, SIM) card of the terminal 100. The kind of the SIM card may refer to the following description about the structure of the terminal 100, which is not repeated here.

Typically, there may be a plurality of operators providing network services, such as china mobile, china corporation, china telecommunications, etc. Terminal 100 may correspond to one or more operators. For example, when a SIM card provided by chinese mobile is installed in the terminal 100, the terminal 100 corresponds to chinese mobile. When a SIM card provided by chinese telecommunication is installed in the terminal 100, the terminal 100 corresponds to chinese telecommunication.

In the following embodiments of the present application, an example will be described in which the terminal 100 corresponds to one operator.

The access network is responsible for connecting the terminal to the core network using wired or wireless communication techniques, providing connectivity of the terminal to the network. The access network includes a network device 200 and a network device 300. The network device 200 and the network device 300 are provided by the operators to which the terminal 100 corresponds, in other words, the network device 200 and the network device 300 belong to the operators to which the terminal 100 corresponds.

The network device 200 is an evolved Node B (eNB) in a 4G/LTE network. The terminals may be connected to the network device 200 and communicate with the network device 200 using an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) air interface technology. In other words, communication between the terminal 100 and the network device 200 is through an LTE link.

The network device 300 is a next generation base station (gNB) in a 5G network. The terminals may connect to the network device 300 and communicate with the network device 300 using a New Radio (NR) access technology. In other words, communication between the terminal 100 and the network device 300 is through an NR link.

In the embodiment of the present application, the network device 200 may be referred to as a first device, and the network device 300 may be referred to as a second device.

The core network is the core of the communication system 10, in which data is exchanged, forwarded, connected, routed. The core network may be a 4G core network (evolved packet core, EPC) or a 5G core network (5G core,5 gc).

When the core network is EPC, the network device 200 and the network device 300 are connected through an X2 interface. In addition, network device 200 is connected to the EPC through an S1 interface, and network device 300 is connected to the EPC through an S1-U.

When the core network is 5GC, the network device 200 and the network device 300 are connected through an Xn interface.

The EPC mainly comprises the following network elements: mobility management entities (mobility management entity, MME), serving Gateway (SGW), packet data network gateway (packet data network gateway, PGW), home subscriber server (home subscriber server, HSS), and application servers, etc. The main functions of the MME include access control, mobility management, attach and detach, session management (e.g., bearer setup, modification, and release), S-GW and P-GW selection, etc. The SGW is mainly used for routing and forwarding data packets under the control of the MME. The main functions of the PGW include a user-based packet filtering function, a lawful interception function, an IP address allocation function of the UE, packet transport layer tagging in uplink/downlink, and the like. The HSS is a server for storing subscription information of users, and is mainly responsible for managing subscription data of users and location information of mobile users.

The network element in 5GC is a functional virtual unit, and may include: a unit AMF (access and mobility management function) for access and mobility management functions, a unit SMF (session management function) for session management functions, UDM (unified data management) for unified data management. The main functions of AMF include: access and mobility management functions, mainly support registration management, connection management, reachability management, mobility management, access authentication, access authorization, etc. The main functions of SMF include: session management functions mainly support session establishment, session modification, session release, UE IP address allocation and management, etc. The UDM is a server for storing subscription information of a user, and is mainly responsible for managing subscription data of the user and location information of the mobile user.

In implementing dual connectivity, terminal 100 may connect with network device 200 (e.g., eNB) and network device 300 (e.g., gNB) in the access network simultaneously and obtain high-rate, low-latency wireless transport services under tight interoperability of 4G networks and 5G networks. A network device serving as a control plane anchor point may be referred to as a Master Node (MN) in the dual connection, and a base station serving as an auxiliary function may be referred to as a Secondary Node (SN). The primary node may also be referred to as a primary station and the secondary node may also be referred to as a secondary station.

Depending on the types of the primary node and the secondary node connected to the terminal 100 and the core network, the following three dual-connection networking modes or deployment modes may be classified:

(1) 4G and 5G dual connectivity based on 4G core network EPC (E-UTRANR dual connection, EN-DC)

In EN-DC, EPC serves as a core network, network device 200 in the access network, e.g. eNB, serves as a master node, and network device 300 in the access network, e.g. gNB, serves as a slave node. Wherein the network device 200 is connected to the EPC through the S1 interface and to the network device 300 through the X2 interface. The network device 300 connects to the EPC through S1-U.

The network device 300 as a secondary node mainly provides the terminal 100 with control plane and user plane protocol end points of the NR, but is not connected to the 5G core network 5GC and may thus also be referred to as en-gNB.

(2) 5G and 4G dual connectivity (NR E-UTRAdual connectivity, NE-DC) based on 5G core network NGC

In NE-DC, 5GC is used as a core network, a network device 300 in an access network, such as a gNB, is used as a master node, and a network device 200 in an access network, such as an eNB, is used as a slave node. In order to establish a connection between the 5GC and the network device 200, the network device 200 needs to be upgraded, and the upgraded network device 200 supports a NG interface protocol, which may be referred to as a NG-eNB.

(3) 4G and 5G dual connectivity based on 5G core network NGC (NG-RAN E-UTRA-NR dual connectivity, NGEN-DC)

In NGEN-DC, 5GC is used as a core network, a network device 200 in an access network, such as an eNB, is used as a master node, and a network device 300 in an access network, such as a gNB, is used as a slave node. Here, the network device 200 may be an upgraded ng-eNB.

When the network is deployed in the (1) th dual connectivity mode, the access network in the communication system 10 may be referred to as an LTE access network (E-UTRAN). When the network is deployed in the (2) or (3) dual connectivity mode, the access network in the communication system 10 may be referred to as a 5G access network (NG-RAN).

Referring to table 1, the core network, the primary node, and the secondary node, respectively corresponding to the above three dual connections, are summarized in table 1.

Dual connection	Core network	Main node	Auxiliary node
				EN-DC	EPC	eNB	gNB
NE-DC	5GC	gNB	eNB
				NGEN-DC	5GC	eNB	gNB

TABLE 1

Currently, the global system for mobile communications association (global system for mobile communications association, GSMA) provides four policies for displaying network identifications as shown in table 2, namely policies corresponding to configuration a (configA), configuration B (configB), configuration C (configC), and configuration D (configD), respectively, in table 2.

Table 2 GSMA provided policies for displaying network identifications

As shown in table 2, the terminal may be in several states:

state 1 is in idle state (Idle under or connected to LTE cell not surporting NSA) in LTE where NSA is not supported.

State 2. In idle state or connected state in NSA enabled LTE and no NR signal is measured (Idle under or connected to LTE cell surporting NSAand no detection of NR coverage).

State 3, connected state in NSA-enabled LTE and NR signal measured (connected to LTE only under LTE cell surporting NSAand detection of NR coverage).

State 4. In idle state in NSA enabled LTE and NR signal is measured (idle under LTE cell surporting NSA and detection of NR coverage).

State 5. Connected state is in both LTE and NR and the LTE supports NSA (connected to lte+ NR under LTE cell surporting NSA).

State 6. In idle state or connected state under 5G access network and attached to 5G core network (idle under or connected to NG-RAN while attached to 5 GC). The NG-RAN includes one or more gnbs connected to the 5GC through an NG interface.

The LTE supporting NSA means that a 4G base station to which a terminal is connected may be connected to a5G base station, and may also be connected to a 4G core network or a5G core network. That is, the terminal has the ability to add NSA5G secondary cells to the terminal. In other words, the 4G base station to which the terminal is connected may be the network device 200 in the communication system shown in fig. 1A. The idle state in LTE refers to a state in which a terminal is located after a radio resource control (radio resource control, RRC) connection between the terminal and a 4G base station is disconnected or released. The connection state under LTE refers to a state in which a terminal is located after RRC connection between the terminal and a 4G base station is established. The measured NR signal means that the terminal measures a signal transmitted from the 5G base station.

State 2-state 5 is a possible state of the terminal when the 5G network is deployed by adopting a dual connectivity networking mode. Table 2 gives four strategies for displaying network identifications for each state, respectively.

With reference to the display policy corresponding to configuration D, when the 4G base station where the terminal resides or is connected supports NSA, the terminal may display the network identifier of the 5G network, and at this time, the terminal may also display a signal grid characterizing the 4G signal strength. In some embodiments, the terminal may determine whether the 4G base station supports NSA through a system message (system information blocks, SIBs) transmitted by the 4G base station at the time of cell selection after cell search. When the 4G base station supports NSA, the SIB2 carried in the SIBs carries a field upperlayerInstruction-r 15, which is used for indicating whether the 4G base station supports NSA. When the value of the field is true, the field is used to indicate that the 4G base station supports NSA. In the embodiment of the present application, the field upperLayerIndication-r15 may be referred to as a first field, and the value true may be referred to as a preset value.

Referring to the display policy corresponding to the configuration C, when the 4G base station where the terminal resides or is connected supports NSA, and the terminal is in a connection state under LTE and measures a 5G signal, the terminal may display a network identifier of the 5G network, and at this time, the terminal may also display a signal lattice representing the strength of the 4G/5G signal.

Referring to the display policy corresponding to the configuration B, when the 4G base station where the terminal resides or is connected supports NSA, and the terminal is in an idle state under LTE and measures the 5G signal, the terminal may display the network identifier of the 5G network, and at this time, the terminal may also display a signal lattice representing the 4G/5G signal strength.

Referring to the display strategy corresponding to the configuration A, when the 4G base station where the terminal resides or is connected supports NSA and the terminal is in a connection state under double connection, the terminal can display the network identification of the 5G network, and at the moment, the terminal can also display a signal lattice representing the 4G/5G signal strength.

According to the display strategy provided by GSMA, under the condition that the terminal is connected to the 4G and 5G networks, the terminal only displays a network identifier and a signal grid, so that the actual network connection condition of the terminal cannot be represented.

Further, referring to fig. 1B, in the display policy corresponding to configuration D used by a part of operators (e.g., vodafone), the network identification of the 5G network is displayed in both state 3 and state 4, but the signal grid characterizing the 5G signal strength is displayed in state 3, and the signal grid characterizing the 4G signal strength is displayed in state 4. By using the display mode, when the terminal is switched between the state 3 and the state 4, the displayed signal grid can jump, and the user experience is affected.

In addition, in the early stages of 5G business, network construction requires a long period, resulting in that coverage of 5G networks may not be good enough for a long time. If the terminal only displays a signal lattice representing the 5G signal strength when the 4G signal is good but the 5G signal is poor, unnecessary anxiety may be brought to a partially sensitive user.

In order to solve the defects in the prior art, the embodiment of the application provides a method for displaying network identifications. In this method, the terminal 100 may display network identifiers of available networks and corresponding signal strength indicators on a display screen in a workflow after power-on, thereby prompting a user of the available networks. In this embodiment of the present application, the terminal 100 displays the network identifier of the 4G network and the signal strength indicator of the 4G network, and the network identifier of the 5G network and the signal strength indicator of the 5G network according to the connection conditions with the 4G network and the 5G network, respectively, where the two types of network identifiers are displayed without mutual influence. This may prompt the user terminal 100 for the actual network conditions.

In the embodiment of the application, the network identifier may be implemented as a visual interface element such as a character, an icon, a text, and the like. For example, the network identification of the 4G network may be the character "4G", the character "LTE", etc., and the network identification of the 5G network may be the character "5G", the character "NR", etc.

In the embodiment of the present application, the signal strength indicator is used to indicate the strength of the signal of the network device received by the terminal 100. The units of the signal strength of the network device received by the terminal 100 may be milliwatt decibels (dBm) or may be independent signal units (alone signal unit, ASU). Specifically, the signal indicator of the 4G network is used to indicate the strength of the signal transmitted by the network device 200 in the 4G network received by the terminal 100. The signal indicator of the 5G network is used to indicate the strength of the signal transmitted by the network device 300 in the 5G network received by the terminal 100.

The signal strength indicator may be implemented in a signal lattice comprising a plurality of signal bars, the signal strength indicator indicating a stronger signal strength the more signal bars are. The specific scaling relationship between the number of signal bars and the signal strength may be preset by the terminal 100. The signal strength indicator may be implemented in other forms, such as, but not limited to, an actual signal strength value (e.g., -50 dBm), without limitation by embodiments of the present application.

The subsequent embodiments will be described in detail with reference to the accompanying drawings, and will not be described in detail here.

The method for displaying the network identifier provided in the embodiment of the present application will be described in detail below based on the above three dual connection methods, respectively.

EN-DC-based network identification display method

First, a signaling flow between devices when EN-DC networking is employed is described. The signaling procedure is formulated by 3 GPP.

Referring to fig. 2, fig. 2 shows a schematic signaling flow between various devices in system 10 when EN-DC networking is employed. In this embodiment of the present application, before each device executes the signaling flow shown in fig. 2, the SIB2 issued by the network device 200 to the terminal 100 carries a field upperLayerIndication-r15, where the value of the field is true, and is used to indicate that the network device 200 supports NSA.

As shown in fig. 2, the signaling flow may include the following processes:

1. initial access procedure of terminal 100 (UE initial access)

In an initial access procedure of the terminal 100, the terminal 100 first transmits an RRC connection request (RRC connection request, RRC CONN REQ) to the network device 200 (e.g., eNB).

The network device 200 then sends RRC connection configuration signaling to the terminal (RRC connection SETUP, RRC connsetup). The RRC connection configuration signaling may include frequency resources, coding schemes, etc. allocated to the terminal 100 by the network device 200. In response to the RRC connection configuration signaling, the terminal 100 replies to the network device 200 with RRC connection setup complete signaling (RRC connection setup complete, RRC CONN SETUP CMP).

The terminal 100 may establish an RRC connection with the network device 200 according to information in the RRC configuration signaling. After successfully establishing the RRC connection, the terminal 100 may perform data interaction with the core network through the network device 200 based on the RRC connection.

Thereafter, the terminal 100 may transmit some access stratum signaling (UL NAS TRANS) to the network device 200, and may also report wireless capability information (see capability detection signaling (UE capability enquiry, UE CAP acquisition), capability information (UE capability, UE CAP) in fig. 2) to the core network under the requirements of the network device 200.

2. The terminal 100 performs a procedure of 5G neighbor cell measurement (5G neighbor measure)

In 5G neighbor cell measurement, the network device 200 first transmits RRC reconfiguration signaling (RRCconnection reconfigration, RRC CONN RECFG) to the terminal 100. The RRC reconfiguration signaling is used to instruct the terminal 100 to measure the 5G cell, and may instruct the terminal 100 to measure the time and frequency point of the 5G cell. In response to the RRC reconfiguration signaling, the terminal 100 replies to the network device 200 with reconfiguration complete signaling (RRC connection reconfiguration complete, RRC CONN RECFG CMP). In the embodiment of the present application, the time carried in the RRC reconfiguration signaling may be referred to as a first time, and the frequency point carried in the RRC reconfiguration signaling may be referred to as a first frequency point.

The terminal 100 may measure the 5G cell at a time and frequency band designated by the network device 200 according to the RRC reconfiguration signaling. After successful measurement of the 5G cell, the terminal 100 replies to the network device 200 with a 5G cell measurement report (measurement report, MEAS RPRT). Here, the 5G cell measured by the terminal 100 belongs to the signal coverage of the network device 300. The terminal 100 measuring the 5G cell means that the terminal 100 receives a signal transmitted from the network device 300.

3. Network device 200 adds a 5G secondary station (5G 5cg add) to terminal 100

After the terminal 100 successfully measures the 5G cell, the network device 200 transmits a secondary station addition request to the network device 300 (SgNB addition request, sgNB Addition Req). The network device 300 then replies to the network device 200 with a secondary addition acknowledgement (SgNB addition request acknowledge, sgNB Addition Req ACK).

Then, the network device 200 transmits RRC connection reconfiguration signaling (RRCconnection reconfigration, RRC CONN RECFG) to the terminal 100 for adding a secondary station (i.e., the network device 300) to the terminal 100. The terminal 100 then resumes RRC connection reconfiguration complete signaling to the network device (RRCconnection reconfigration complete, RRC CONN RECFG CMP). Thereafter, the network device 200 transmits secondary station addition completion signaling (secondary gNB reconfiguration complete, sgNB RECFG CMP) to the network device 200. To this end, the network device 200 successfully adds a secondary station (i.e., the network device 300) to the terminal 100.

The terminal 100 may then attempt to access the network device 300, i.e. perform a random access procedure (random access) between the terminal 100 and the network device 300. After the random access procedure is completed, a communication link may be established between the terminal 100 and the network device 300, and the terminal 100 may perform data interaction with the core network through the communication link. Up to this point, the terminal 100 establishes a connection with the network device 200, respectively, i.e. the terminal 100 establishes a dual connection. Subsequently, the terminal 100 may perform data interaction with the core network through the network device 200, or may perform data interaction with the core network through the network device 300.

It is understood that the signaling flow shown in fig. 2 is only an example, and the detailed signaling interaction procedure between the devices in EN-DC may refer to the standard provided by 3 GPP.

Based on the EN-DC based signaling procedure shown in fig. 2, the terminal 100 may display a network identification and a signal strength indicator corresponding to the network identification in the course of performing the signaling procedure. The method for displaying EN-DC based network identifications performed by the terminal 100 will be described in detail with reference to the accompanying drawings.

Referring to fig. 3A, fig. 3A illustrates that the terminal 100 displays a network identification of the 4G network and a start-stop time of a corresponding signal strength indicator, and displays a network identification of the 5G network and a start-stop time of a corresponding signal strength indicator in performing the signaling process illustrated in fig. 2.

First, how the terminal 100 displays the network identification of the 4G network and the corresponding signal strength indicator in the embodiment of fig. 3A will be described.

Referring to the solid gray rectangle corresponding to 4G in fig. 3A, in some embodiments, the terminal 100 may start to display the network identification of the 4G network after the RRC connection is successfully established with the network device 200 for the first time after power-on, i.e., after the time point T2. The network identifier of the 4G network is used to indicate: the terminal 100 is connected to the network device 200 in the 4G network, i.e. the terminal 100 may interact with the core network via the network device in the 4G network. In a specific embodiment, the terminal 100 may start displaying the network identifier of the 4G network after replying to the network device 200 with the RRC connection setup complete signaling (RRC CONN SETUP CMP) for the first time after power-on.

Referring to the dashed gray rectangle corresponding to 4G in fig. 3A, in some embodiments, the terminal 100 may also start displaying the network identification of the 4G network when the 4G cell is measured for the first time after power-on, i.e. at the time point T1. The network identifier of the 4G network is used to indicate: the terminal 100 measures a 4G cell. T1 is earlier than T2. The terminal 100 measuring the 4G cell means that the terminal 100 receives a signal transmitted from the network device 200 and measures its signal strength.

In some embodiments, the terminal 100 stops measuring the 4G cell and stops displaying the network identity of the 4G network when the 4G cell is not measured beyond the second preset time period, i.e., at the time point T6. The situation that the terminal does not measure the 4G cell beyond the second preset duration may include, but is not limited to: the terminal 100 enters the flight mode or is powered off and the terminal 100 is not within the signal coverage of the network device 200.

In the embodiment of fig. 3A, in the process of displaying the network identifier of the 4G network, if the terminal 100 measures the 4G cell, a signal strength indicator of the 4G network may be displayed at the same time, where the signal strength indicator of the 4G network is used to indicate the strength of the signal sent by the network device 200 measured by the terminal 100.

In some embodiments, in starting to measure the 4G cell (i.e., time point T1) to the 4G cell (i.e., time point T6), the terminal 100 may periodically measure the 4G cell and determine the strength of the measured signal transmitted by the network device 200, and update the signal strength indicator of the 4G network when the strength of the signal transmitted by the network device 200 is changed. The period for the terminal 100 to measure the 4G cell may be preset and stored in the terminal 100.

Then, it is described how the terminal 100 displays the network identification of the 5G network and the corresponding signal strength indicator in the embodiment of fig. 3A.

Referring to the solid gray rectangle corresponding to 5G in fig. 3A, in some embodiments, terminal 100 may begin displaying the network identification of the 5G network after a successful connection is established with network device 300, i.e., at time point T4. The network identifier of the 5G network is used to indicate: the terminal 100 is connected to the network device 300 in the 5G network, i.e. the terminal 100 may interact with the core network via the network device in the 5G network. Referring to fig. 1A, successful establishment of a connection by the terminal 100 and the network device 300 means that the terminal 100 successfully performs a random access procedure (random access) with the network device 300.

Referring to the dashed gray rectangle corresponding to 5G in fig. 3A, in some embodiments, the terminal 100 may also start displaying the network identification of the 5G network after measuring the 5G cell, i.e., at the time point T3. The network identifier of the 5G network is used to indicate: the terminal 100 measures a 5G cell. T3 is earlier than T4. Referring to fig. 2, the terminal 100 may start measuring the 5G cell after receiving RRC reconfiguration signaling RRC connrecfg transmitted by the network device 200. Here, the manner in which the terminal 100 measures the 5G cell may be described with reference to the correlation in fig. 1A.

In the fig. 3A embodiment, in some cases, terminal 100 may stop measuring 5G cells and stop displaying network identifications of the 5G networks at point in time T5. The time point T5 may include, but is not limited to:

1. the terminal 100 is in a connected state of LTE (connected to LTE) and does not measure the 5G cell beyond a first preset duration. Here, after the terminal 100 and the network device 200 establish the RRC connection, the terminal is in the LTE connected state before the RRC connection is disconnected or released (RRC release).

2. When the network device 200 deletes the secondary station (delete 5G cell) of the terminal 100, that is, when the terminal 100 receives the signaling for deleting the secondary station transmitted by the device 200.

3. The terminal 100 is in an idle state under LTE (idle under LTE), or when the terminal 100 is in an idle state under LTE and no 5G cell is measured beyond a first preset duration. Here, after the RRC connection between the terminal 100 and the network device 200 is broken or released, the terminal 100 is in an idle state under LTE.

In the embodiment of the present application, the sequence of T5 and T6 is not limited, and T5 may be earlier than T6, may be later than T6, and may be the same as T6.

In the embodiment of fig. 3A, in the process of displaying the network identifier of the 5G network, if the 5G cell is measured, the terminal 100 may simultaneously display a signal strength indicator of the 5G network, where the signal strength indicator of the 5G network is used to indicate the strength of the signal sent by the network device 300 measured by the terminal 100. In some embodiments, in starting to measure 5G cells to less than 5G cells (i.e., point T5) in response to RRC reconfiguration signaling, terminal 100 may periodically measure 5G cells and determine the strength of the measured signal transmitted by network device 300 and update the signal strength indicator of the 5G network when the strength of the signal transmitted by network device 300 changes. The period for the terminal 100 to measure the 5G cell may be preset and stored in the terminal 100.

Referring to fig. 3C, fig. 3C illustrates a network identification and signal strength indicator displayed by the terminal 100 on a display screen based on the display scheme shown in fig. 3A.

As shown in fig. 3C, the user interface 31 displayed on the terminal 100 may include: status bar 301, area 301. Wherein the status bar 101 includes a network identification and signal strength indicator, time indicator, battery status indicator, etc. of the network. In some embodiments, status bar 101 may also include an operator name, a signal strength indicator for wireless high fidelity (wireless fidelity, wi-Fi) signals, and so forth, to which embodiments of the present application are not limited. An application icon (e.g., an icon of gallery, an icon of the instant messaging application hi chat, a memo icon, etc.), a weather indicator, etc., are displayed in the area 102.

As shown in fig. 3C:

at T1 or T2, terminal 100 starts displaying network identification 301a of the 4G network and signal strength indicator 301b of the 4G network in status bar 301.

At T3 or T4, terminal 100 displays network identifier 301a of the 4G network and signal strength indicator 301b of the 4G network in status bar 301, and displays network identifier 301c of the 5G network and signal strength indicator 301d of the 5G network in status bar 301.

At T5, terminal 100 stops displaying network identifier 301c of the 5G network and signal strength indicator 301d of the 5G network in status bar 301.

At T6, the terminal 100 stops displaying the network identification 301a of the 4G network and the signal strength indicator 301b of the 4G network in the status bar 301.

It is understood that fig. 3C is only an example, and that the signal strength indicators 301b of the 4G network displayed by different time nodes may be different for indicating different signal strengths. For example, the signal strength indicated by the signal strength indicator 301b of the 4G network at T1 is stronger than the signal strength indicated by the signal strength indicator 301b of the 4G network at T5. Similarly, the signal strength indicators 301d of the 5G network displayed by different time nodes may be different to indicate different signal strengths.

Instead of limiting the display of the network identification and the signal strength indicator in the status bar, in other embodiments, the terminal 100 may display the network identification and the signal strength indicator in other areas of the display, which embodiments of the present application do not limit.

The network identifications and signal strength indicators shown in fig. 3C are merely examples and should not be construed as limiting embodiments of the present application. The network identification may also be implemented in other forms, without being limited to characters, as described in relation to the foregoing. The signal strength indicator may also be implemented in other forms, not limited to the signal grid, as described in relation to the foregoing.

While the terminal 100 simultaneously displays the network identifier of the 4G network, the signal strength indicator, and the network identifier of the 5G network, the signal strength indicator in the status bar 301, the terminal 100 may be displayed in other forms, not limited to the side-by-side display manner shown in fig. 3C. For example, referring to fig. 3D, the terminal 100 may also display two network identifications and corresponding signal strength indicators one above the other. For another example, the signal strength indicator of the 4G network and the signal strength indicator of the 5G network may also be partially displayed overlapping, and the display colors of the two may be different.

It will be appreciated that the content displayed in the area 102 shown in fig. 3C is only an example and should not be construed as limiting the embodiments of the present application in the process of displaying network identifications and signal strength indicators by the terminal 100. Further, in this process, the content displayed in the area 102 may vary with the user operation, which is not limited by the embodiment of the present application.

Through the network identification scheme shown in fig. 3A, in a network deployed by using EN-DC, the terminal 100 may display a corresponding network identification and a signal strength indicator according to an actual network condition, feedback the actual network condition for a user, so as to improve user experience, and facilitate the user to use a service provided by the terminal 100 according to the actual network condition.

Referring to fig. 3B, fig. 3B illustrates that the terminal 100 displays a network identity of the 4G network and a start-stop time of a corresponding signal strength indicator, and displays a network identity of the 5G network and a start-stop time of a corresponding signal strength indicator in case that the 5G cell is not successfully measured while performing step 2 in the signaling procedure illustrated in fig. 2.

In some embodiments, network device 200 and network device 300 may be located at the same physical location, and when the signal coverage of network device 200 is greater than the signal coverage of network device 300, the location of terminal 100 may be located within the signal coverage of network device 200, but not within the signal coverage of network device 300 or at the edge of the signal coverage of network device 300. In this case, the terminal can receive the RRC reconfiguration signaling transmitted to the terminal by the network device 200 in fig. 2, but cannot measure the signal transmitted by the network device 300 when measuring the 5G cell in response to the RRC reconfiguration signaling.

In the embodiment of fig. 3B, the manner in which the terminal 200 measures the 4G cell, the network identifier of the 4G network and the start-stop time and manner of the corresponding signal strength indicator are displayed by the terminal 200, and so on, are the same as those in the embodiment of fig. 3A, and reference is made to the related description, which is not repeated here.

The following describes how the terminal 100 displays the network identity of the 5G network and the corresponding signal strength indicator in the embodiment of fig. 3B.

In the embodiment of the present application, in step 2 shown in fig. 2, if the terminal 100 fails to measure the 5G cell in response to the RRC reconfiguration signaling sent by the network device 200, i.e., the terminal 100 fails to measure the 5G cell successfully, the terminal 100 does not continue to perform the subsequent steps in the signaling process shown in fig. 2, for example, step 3.

The terminal 100 may autonomously measure the 5G cell after the failure of measuring the 5G cell and start displaying the network identity of the 5G network when the 5G cell is measured, i.e., at the time point T7. The network identifier of the 5G network is used to indicate: the terminal 100 measures a signal transmitted from the network device 300 in the 5G network.

In some embodiments, if the terminal 100 autonomously measures the 5G cell in a connected to LTE (LTE), the terminal 100 may measure the 5G cell by one or more of the following: no-gap measurement mode, or, appointed frequency point measurement mode. After establishing an RRC connection between the terminal 100 and the network device 200, the terminal 100 is in a connected state under LTE before the RRC connection is disconnected or released.

In some embodiments, if the terminal 100 autonomously measures the 5G cell while in an idle state under LTE (idle under LTE), the terminal 100 may measure the 5G cell by one or more of: background search mode, or appointed frequency point measurement mode.

The background search mode refers to: the terminal 100 periodically performs a full frequency search on all frequency bands (bands) supported by the terminal 100, thereby measuring 5G cells. The period may be a discontinuous reception (discontinuous reception, DRX) period corresponding to an idle state of the terminal 100 in LTE.

The no-gap measurement mode refers to: the terminal 100 measures a 5G cell on a frequency point to be measured while continuously receiving a signal transmitted from the network device 200. In this case, the terminal 100 may directly measure the 5G cell without configuring the measurement gap. The frequency point to be measured may be a frequency point designated by the network device 200 in RRC reconfiguration signaling.

The designated frequency point measurement mode is as follows: the terminal 100 searches for a 5G cell on a designated frequency point, i.e., receives a signal transmitted by the network device 300 on the designated frequency point. The designated frequency point may include one or more of the following: the frequency point where the 5G cell where the terminal 100 resides historically, the frequency point specified by the operator stored in the SIM card installed on the terminal 100, the 5G frequency point corresponding to or available to the operator to which the LTE cell where the terminal 100 resides currently belongs, or the frequency point searched by the background search method. In the embodiment of the present application, the designated frequency point may be referred to as a second frequency point.

In the fig. 3B embodiment, terminal 100 may stop measuring 5G cells and stop displaying network identifications of the 5G network at point in time T8. The time point T8 may refer to the 2 nd or 3 rd case of the time point T5 in the embodiment of fig. 3A, and is not described herein.

In the embodiment of fig. 3B, in the process of displaying the network identifier of the 5G network, if the 5G cell is measured, the terminal 100 may simultaneously display a signal strength indicator of the 5G network, where the signal strength indicator of the 5G network is used to indicate the strength of the signal sent by the network device 300 measured by the terminal 100. In some embodiments, during the process of the terminal 100 starting autonomous measurement of 5G cells to less than 5G cells (i.e., point T8), the terminal 100 may periodically measure 5G cells and determine the strength of the measured signal transmitted by the network device 300, and update the signal strength indicator of the 5G network when the strength of the signal transmitted by the network device 300 changes. The period for the terminal 100 to measure the 5G cell may be preset and stored in the terminal 100.

Referring to fig. 3E, fig. 3E illustrates network identifications and signal strength indicators displayed by the terminal 100 on a display screen based on the display scheme shown in fig. 3B. The user interface 32 in fig. 3E is the same as the user interface 31 in fig. 3C, and reference is made to the relevant description.

As shown in fig. 3E:

At T7, terminal 100 displays network identifier 301a of the 4G network and signal strength indicator 301b of the 4G network in status bar 301, and displays network identifier 301c of the 5G network and signal strength indicator 301d of the 5G network in status bar 301.

At T8, the terminal 100 stops displaying the network identifier 301c of the 5G network and the signal strength indicator 301d of the 5G network in the status bar 301.

Through the network identification scheme shown in fig. 3B, in the network deployed by using EN-DC, the terminal 100 may display the corresponding network identification and the signal strength indicator according to the actual network situation, so as to feed back the actual network situation for the user, improve the user experience, and also facilitate the user to use the service provided by the terminal 100 according to the actual network situation.

Referring to fig. 4, fig. 4 is a flowchart schematically illustrating a method for displaying network identifications performed by the terminal 100 in a network employing EN-DC networking. As shown in fig. 4, the method may include the steps of:

S101, the terminal 100 receives the system message sent by the network device 200.

S102, the RRC communication connection is established between the terminal 100 and the network equipment 200, and the network identification of the 4G network is displayed. The network identifier of the 4G network is used to indicate: the terminal 100 is connected to a network device 200 in a 4G network.

In some embodiments, the terminal 100 may further display a signal strength indicator of the 4G network when displaying the network identification of the 4G network, where the signal strength indicator of the 4G network is used to indicate the strength of the signal transmitted by the network device 200 measured by the terminal 100.

S103, the terminal 100 judges whether the value of the field upper layerIndustionIndustionr 15 contained in the system message is a preset value.

The meaning of the field upperLayerIndication-r15 in the system message in step S103 may be referred to the relevant description of the previous embodiments. The preset value may be "true".

The embodiment of the present application does not limit the order of execution of step S102 and step S103.

S104, if the system message includes a field upperlayerIndustionR 15, the terminal 100 receives an RRC reconfiguration signaling RRC CONN RECFG sent by the network device 200, and measures the 5G cell in response to the RRC reconfiguration signaling.

Here, the manner in which the terminal 100 measures the 5G cell in response to the RRC reconfiguration signaling may be referred to the related description of the previous embodiments.

S105, the terminal 100 determines whether the 5G cell is successfully measured.

And S106, if the measurement operation is successful, namely, the 5G cell is measured, the terminal 100 displays the network identification of the 5G network. The network identifier of the 5G network is used to indicate: the terminal 100 measures a signal transmitted from the network device 300 in the 5G network.

S107, in case that the measurement operation fails, i.e., the 5G cell is not measured, the terminal 100 measures the 5G cell again, and displays the network identification of the 5G network when the 5G cell is measured. The network identifier of the 5G network is used to indicate: the terminal 100 measures a signal transmitted from the network device 300 in the 5G network.

Specifically, when the terminal 100 measures the 5G cell again in step S107, different measurement modes may be adopted according to different states of the terminal 100. That is, step S107 may be divided into the following steps:

s1071, the terminal 100 determines the current state.

S1072, if the terminal 100 is in a connected state under LTE (connected to LTE), the terminal 100 measures the 5G cell by one or more of the following ways: no-gap measurement mode, or, appointed frequency point measurement mode.

S1073, if the terminal 100 is in an idle state under LTE (idle under LTE), the terminal 100 measures the 5G cell by one or more of the following ways: background search mode, or appointed frequency point measurement mode.

S1074, displaying the network identification of the 5G network when the 5G cell is measured.

In some embodiments, the terminal 100 may further display a signal strength indicator of the 5G network when displaying the network identification of the 5G network, where the signal strength indicator of the 5G network is used to indicate the strength of the signal transmitted by the network device 200 measured by the terminal 100.

Specific implementations of the steps S101-S107 may refer to fig. 2, 3A-3E and related descriptions, and are not repeated here.

(II) NGEN-DC-based network identification display method

When NGEN-DC networking is employed, the signaling flow between the various devices in system 10 is similar to that shown in fig. 2. The difference is that when NGEN-DC networking is adopted, the core network is 5GC.

Referring to fig. 5A and 5B, fig. 5A and 5B illustrate one way in which the terminal 100 displays a network identification.

Fig. 5A illustrates a start-stop time of displaying a network identifier of a 4G network and a corresponding signal strength indicator, and a start-stop time of displaying a network identifier of a 5G network and a corresponding signal strength indicator in a process of smoothly performing signaling by the terminal 100. Fig. 5B shows that in case that the terminal 100 does not successfully measure the 5G cell in the signaling procedure, the network identity of the 4G network and the start-stop time of the corresponding signal strength indicator are displayed, and the network identity of the 5G network and the start-stop time of the corresponding signal strength indicator are displayed.

Regarding the manner in which the terminal 100 measures the 4G cell, the network identifier of the 4G network and the start-stop time and the display manner of the corresponding signal strength indicator, the manner in which the 5G cell is measured, the network identifier of the 5G network and the start-stop time and the display manner of the corresponding signal strength indicator, the indication meaning of the 4G network identifier, the indication meaning of the 5G network, etc. in the embodiments of fig. 5A to 5B, reference may be made to the related descriptions of the embodiments of fig. 3A to 3E, and the description thereof will be omitted.

Referring to fig. 5C and 5D, fig. 5C and 5D illustrate another way in which the terminal 100 displays a network identification.

Referring to fig. 5C, fig. 5C illustrates that the terminal 100 displays a network identification of the 4G network and a start-stop time of a corresponding signal strength indicator, and displays a network identification of the 5G network and a start-stop time of a corresponding signal strength indicator in a smooth signaling process.

In the embodiment of fig. 5C, the manner in which the terminal 100 measures the 4G cell, the start-stop time and the display manner of the terminal 100 displaying the network identifier of the 4G network and the corresponding signal strength indicator, the indication meaning of the 4G network identifier, and the like are the same as those in the embodiment of fig. 3A, and reference may be made to the related description, which is not repeated here.

The following describes how the terminal 100 displays the network identity of the 5G network and the corresponding signal strength indicator in the embodiment of fig. 5C.

In some embodiments, the terminal 100 may start displaying the network identification of the 5G network after establishing an RRC connection (i.e., point T2) with the network device 200 in the 4G network. Since the core network in the system 10 is 5GC when the NGEN-DC networking is adopted, the network identifier of the 5G network displayed by the terminal 100 is used to indicate: the terminal 100 may perform data transmission with the 5 GC.

In some embodiments, the terminal 100 may stop measuring 5G cells and stop displaying network identifications of the 5G network at the time point T5. The time point T5 may be referred to as related description of the embodiment of fig. 3A.

In some embodiments, in displaying the network identifier of the 5G network, if the 5G cell is measured, the terminal 100 may simultaneously display a signal strength indicator of the 5G network, where the signal strength indicator of the 5G network is used to indicate the strength of the signal sent by the network device 300 measured by the terminal 100. In some embodiments, in starting to measure 5G cells to less than 5G cells (i.e., point T5) in response to RRC reconfiguration signaling, terminal 100 may periodically measure 5G cells and determine the strength of the measured signal transmitted by network device 300 and update the signal strength indicator of the 5G network when the strength of the signal transmitted by network device 300 changes. The period for the terminal 100 to measure the 5G cell may be preset and stored in the terminal 100.

In other embodiments, in displaying the network identifier of the 5G network, if the 5G cell is not measured, the terminal 100 may display the signal strength indicator of the 4G network corresponding to the network identifier of the 5G network.

In some embodiments, in displaying the network identifier of the 5G network, if the 5G cell is measured, the terminal 100 may simultaneously display a signal strength indicator of the 5G network, where the signal strength indicator of the 5G network is used to indicate the strength of the signal sent by the network device 300 measured by the terminal 100. In some embodiments, during the initial autonomous measurement of the 5G cell by the terminal 100 (i.e., point T8), the terminal 100 may periodically measure the 5G cell and determine the strength of the signal transmitted by the measured network device 300, and update the signal strength indicator of the 5G network when the strength of the signal transmitted by the network device 300 changes. The period for the terminal 100 to measure the 5G cell may be preset and stored in the terminal 100.

(III) display method of network identification based on NE-DC

When NGEN-DC networking is employed, the signaling flow between the various devices in system 10 is similar to that shown in fig. 2. Except that when the NGEN-DC networking is employed, the core network is 5GC and the roles of the network device 200 and the network device 300 are interchanged. In other words, when the ngan-DC networking is adopted, the terminal 100 establishes an RRC connection with the network device 300, performs 4G neighbor cell measurement, and adds a secondary station (i.e., the network device 200) to the terminal 100 by the network device 300.

Referring to fig. 6A and 6B, fig. 6A and 6B illustrate one way in which the terminal 100 displays a network identification.

Fig. 6A illustrates a start-stop time of displaying a network identifier of a 4G network and a corresponding signal strength indicator, and a start-stop time of displaying a network identifier of a 5G network and a corresponding signal strength indicator in a smooth signaling process of the terminal 100. Fig. 6B shows that in case that the terminal 100 does not successfully measure the 4G cell in the signaling procedure, the network identity of the 4G network and the start-stop time of the corresponding signal strength indicator are displayed, and the network identity of the 5G network and the start-stop time of the corresponding signal strength indicator are displayed.

In some embodiments, network device 200 and network device 300 may be located at the same physical location, and when the signal coverage of network device 300 is greater than the signal coverage of network device 200, the location of terminal 100 may be located within the signal coverage of network device 300, but not within the signal coverage of network device 200 or at the edge of the signal coverage of network device 200. In this case, the terminal can receive RRC reconfiguration signaling sent by the network device 300 to the terminal for instructing it to measure the 4G cell, but cannot measure a signal sent by the network device 200 when the 4G cell is measured in response to the RRC reconfiguration signaling.

Regarding the manner in which the terminal 100 measures the 4G cell, the network identifier of the 4G network and the start-stop time and manner of the corresponding signal strength indicator in the embodiments of fig. 6A and 6B, reference may be made to the manner in which the terminal 100 measures the 5G cell, the manner in which the network identifier of the 5G network and the start-stop time and manner of the corresponding signal strength indicator in the embodiments of fig. 3A and 3B, respectively.

Regarding the manner in which the terminal 100 measures the 5G cell, displays the network identifier of the 5G network and the start-stop time and manner of the corresponding signal strength indicator in the embodiments of fig. 6A and 6B, reference may be made to the manner in which the terminal 100 measures the 4G cell, displays the network identifier of the 4G network and the start-stop time and manner of the corresponding signal strength indicator in the embodiments of fig. 3A and 3B, respectively.

Referring to fig. 1A, successful establishment of a connection by the terminal 100 and the network device 200 means that the terminal 100 successfully performs a random access procedure (random access) with the network device 200.

In some embodiments, the terminal 100 may stop measuring the 5G cell and stop displaying the network identity of the 5G network when the 5G cell is not measured beyond the second preset time period, i.e., at the time point T6'. The situation that the terminal does not measure the 5G cell beyond the second preset duration may include, but is not limited to: the terminal 100 enters the flight mode or is powered off and the terminal 100 is not within the signal coverage of the network device 300.

In some embodiments, the terminal 100 may stop measuring the 4G cell and stop displaying the network identity of the 4G network at the time point T5'. The time point T5' may include, but is not limited to:

1. the terminal 100 is in a connected to NG-RAN (connected to NG-RAN) state under NG-RAN, and when the 4G cell is not measured beyond the first preset time period. Here, after the terminal 100 and the network device 300 establish the RRC connection, the terminal is in the NG-RAN connected state before the RRC connection is disconnected or released (RRC release).

2. When the network device 300 deletes the secondary station (delete 4G cell) of the terminal 100, that is, when the terminal 100 receives the signaling for deleting the secondary station sent by the device 300.

3. The terminal 100 is in an idle state under NG-RAN (idle under NG-RAN), or the terminal 100 is in an idle state under NG-RAN and no 4G cell is measured beyond a first preset period of time.
