Applying.

Technical field

This application relates to the field of mobile communication technology, in particular to a method, device and system for displaying network identifications.

Background technique

With the development of the 5th generation mobile networks (5G) technology, the 3rd generation partnership project (3GPP) has released standalone (SA) networking and networking solutions for the deployment of 5G networks. Non-standalone (NSA) networking has two 5G standards.

Due to small investment and fast network construction, NSA networking based on long term evolution (LTE) networks is a current research hotspot. The NSA network uses multi-standard dual connectivity (MR-DC) to deploy the network. Dual connectivity means that a user terminal (user equipment, UE) is connected to both LTE access network (radio access network, RAN) equipment and 5G access network equipment. One of the access network equipment is the master node and the other access network equipment is The secondary node, and the UE establishes a connection with the same core network through the primary node and the secondary node respectively.

Normally, the UE will display the network identification of the currently available network on the display screen to remind the user of the currently available network. Under the dual connection in the NSA network, how the UE prompts the user about the currently available network is a current research hotspot.

Summary of the invention

The embodiments of the present application provide a method, device, and system for displaying a network identifier. The terminal can display the network identification of the 4G network and the network identification of the 5G network according to the connection conditions of the 4G network and the 5G network respectively, and the display of the two network identifications does not affect each other. This can prompt the actual network status of the user terminal.

In the first aspect, an embodiment of the present application provides a method for displaying a network identity. The method may include: a terminal displays a first identity and a first indicator; the terminal receives radio resource control RRC reconfiguration signaling sent by the first device In response to the RRC reconfiguration signaling, the terminal measures the signal sent by the second device; the terminal measures the signal sent by the second device; the terminal displays the second identifier and the second indicator. Wherein, the terminal and the first device communicate through a long-term evolution LTE link, and the terminal and the second device communicate through a new wireless NR link; the first device and the second device are connected; the first device is connected to the second device. The identifier is used to indicate that the terminal is connected to the first device or that the terminal measures the signal sent by the first device, and the first indicator is used to indicate the strength of the signal sent by the first device measured by the terminal; The second identifier is used to indicate that the terminal measures the signal sent by the second device, and the second indicator is used to indicate the strength of the signal sent by the second device measured by the terminal.

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

In implementing the method of the first aspect, the terminal displays the first identifier and the first indicator at the same time, and if the signal sent by the second device is measured, the second identifier and the second indicator are displayed at the same time. In this way, the terminal can display the corresponding network identifier and signal strength indicator according to the actual network situation, and feedback the real network situation to the user, so that the user can use the service provided by the terminal according to the real network situation, thereby improving the user experience.

With reference to the first aspect, in some embodiments, both the first identifier and the second identifier may be implemented as visual interface elements such as characters, icons, and text. For example, the first identifier may be the characters "4G", the characters "LTE", etc., and the second identifier may be the characters "5G", the characters "NR", and so on.

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

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 the signal sent by the first device, the terminal may measure the first identifier and the first indicator before displaying the first identifier and the first indicator.

With reference to the first aspect, in some embodiments, the terminal may periodically measure the signal sent by the second device, and update the second indicator according to the measured strength of the signal sent by the second device. In this way, the actual network status of the terminal can be prompted to the user, and the user experience can be improved.

With reference to the first aspect, in some embodiments, the terminal may also stop displaying the second identifier and the second indicator in any one of the following situations: the terminal does not measure the first indicator for more than a second preset time period. When the signal sent by the device, when the terminal receives the signaling for deleting the secondary station sent by the first device, or when there is no RRC connection between the terminal and the first device.

With reference to the first aspect, in some embodiments, the terminal may periodically measure the signal sent by the first device, and update the first indicator according to the measured strength of the signal sent by the first device.

Referring to FIG. 1A, FIG. 1A is a schematic structural diagram of a communication system 10 provided by 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, etc., which are networked through NSA networking. The communication system 10 includes: a terminal 100, an access network (RAN), and a core network (core network, CN).

In the embodiments of the present application, the terminal may be referred to as UE.

In the embodiment of the present application, the terminal 100 stores user information, and can communicate with the access network and the core network in the communication system 10 based on the user information, thereby using the network service provided by the operator corresponding to the terminal 100 , Such as voice call service, video service, etc. The user information may include, but is not limited to: international mobile subscriber identification number (IMSI), authentication and encryption information Ki, IMSI authentication algorithm, encryption key generation algorithm A5, and so on.

When the SIM card provided by China Telecom is installed in the terminal 100, the terminal 100 corresponds to China Telecom.

In the following embodiments of the present application, the terminal 100 corresponds to an operator as an example for description.

The access network is responsible for connecting the terminal to the core network using wired or wireless communication technology, and providing the connection between the terminal and the network. The access network includes network equipment 200 and network equipment 300. The network device 200 and the network device 300 are provided by the operator corresponding to the terminal 100. In other words, the network device 200 and the network device 300 belong to the operator corresponding to the terminal 100.

The terminal may be connected to the network device 200, and communicate with the network device 200 using orthogonal frequency division multiplexing (OFDM) air interface technology. In other words, the terminal 100 and the network device 200 communicate through an LTE link.

The network device 300 is a next generation NodeB (gNB) in a 5G network. The terminal can be connected to the network device 300, and communicate with the network device 300 using a new radio (NR) access technology. In other words, the terminal 100 and the network device 300 communicate through the NR link.

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

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

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

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

The EPC mainly includes the following network elements: mobility management entity (MME), serving gateway (serving gateway, SGW), packet data network gateway (PGW), home subscriber server (home subscriber server) , HSS) and application servers. The main functions of MME include access control, mobility management, attach and detach, session management (such as bearer establishment, modification, and release), selection of S-GW and P-GW, etc. The SGW is mainly used to route and forward data packets under the control of the MME. The main functions of the PGW include user-based packet filtering, lawful interception, UE IP address allocation, and data packet transmission layer marking in the uplink/downlink. HSS is a server that stores user subscription information, and is mainly responsible for managing user subscription data and mobile user location information.

When dual connectivity is implemented, the terminal 100 can be connected to the network equipment 200 (e.g., eNB) and network equipment 300 (e.g., gNB) in the access network at the same time, and obtain high speed, Low-latency wireless transmission service. In dual connectivity, the network device serving as the anchor point of the control plane may be referred to as a master node (master node, MN), and the base station that plays an auxiliary role is referred to as a secondary node (secondary node, SN). The master node may also be called the master station, and the auxiliary node may also be called the auxiliary station.

According to the types of the primary and secondary nodes connected to the terminal 100 and the difference in the core network, it can be divided into the following three dual-connection networking modes or deployment modes:

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

In the EN-DC, the EPC is used as the core network, the network device 200 in the access network, such as the eNB, is used as the master node, and the network device 300 in the access network, such as gNB, is used as the secondary node. Among them, the network device 200 is connected to the EPC through the S1 interface, and is connected to the network device 300 through the X2 interface. The network device 300 is connected to the EPC through S1-U.

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

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

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

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

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

When the (1) dual-connection mode is used to deploy the network, the access network in the communication system 10 may be referred to as an LTE access network (evovled UTRAN, E-UTRAN). When the (2) or (3) dual connection mode is used to deploy the network, the access network in the communication system 10 may be referred to as a 5G access network (next generation RAN, NG-RAN).

Refer to Table 1. Table 1 summarizes the core network, master node, and auxiliary node corresponding to the above three dual connections. Refer to Table 1. Table 1 summarizes the core network, master node, and auxiliary node corresponding to the above three dual connections. .

At present, the Global System for Mobile Communications Association (GSMA) provides four strategies for displaying network identifiers as shown in Table 2. That is, the strategies in Table 2 correspond to configuration A (configA) and configuration B (configB). ), configuration C (configC), configuration D (configD) strategy.

Table 2 Strategies for displaying network identification provided by GSMA

As shown in Table 2, the terminal may be in the following states:

State 1. In the idle state under LTE that does not support NSA (Idle under or connected to LTE cell not surporting NSA).

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

State 3, in the connected state under LTE supporting NSA and NR signal is measured (connected to LTE only under LTE cell surporting NSA and detection of NR coverage).

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

State 5. It is in the connected state of LTE and NR at the same time and the LTE supports NSA (connected to LTE+NR under LTE cell surporting NSA).

State 6. It is in the idle state or connected state under the 5G access network and attached to the 5G core network (idle under or connected to NG-RAN while attached to 5GC). NG-RAN includes one or more gNBs connected to 5GC through NG interface.

Among them, LTE supporting NSA means that the 4G base station to which the terminal is connected can be connected to a 5G base station, and can also be connected to a 4G core network or a 5G core network. That is, the terminal has the ability to add NSA 5G secondary cells for 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 the state that the terminal is in after the radio resource control (Radio Resource Control, RRC) connection between the terminal and the 4G base station is disconnected or released. The connected state under LTE refers to the state that the terminal is in after the RRC connection between the terminal and the 4G base station is established. Measured NR signal means that the terminal measures the signal sent by the 5G base station.

State 2-State 5 are possible states of the terminal when a 5G network is deployed in a dual-connection networking mode. Table 2 provides four strategies for displaying network identification corresponding to each state.

Referring to the display strategy corresponding to configuration D, when the 4G base station to which the terminal resides or is connected supports NSA, the terminal can display the network identity of the 5G network, and the terminal can also display the signal grid that characterizes the 4G signal strength. In some embodiments, the terminal may determine whether the 4G base station supports NSA through system messages (system information blocks, SIBs) sent by the 4G base station during cell selection after the cell search. When the 4G base station supports NSA, the SIB2 carried in the SIBs carries the field upperLayerIndication-r15, which is used to indicate whether the 4G base station supports NSA. When the value of this field is true, this field is used to indicate that the 4G base station supports NSA. In this embodiment of the present application, the field upperLayerIndication-r15 may be referred to as the first field, and the value true may be referred to as a preset value.

Refer to the display strategy corresponding to configuration C. The 4G base station to which the terminal resides or is connected supports NSA. When the terminal is connected under LTE and the 5G signal is measured, the terminal can display the network identification of the 5G network. At this time, the terminal can also Display the signal grid that characterizes the 4G/5G signal strength.

Refer to the display strategy corresponding to configuration B. The 4G base station to which the terminal resides or is connected supports NSA. When the terminal is in the idle state under LTE and 5G signals are measured, the terminal can display the network identity of the 5G network. At this time, the terminal can also Display the signal grid that characterizes the 4G/5G signal strength.

Referring to the display strategy corresponding to configuration A, the 4G base station to which the terminal resides or is connected supports NSA. When the terminal is in the dual connection state, the terminal can display the network identifier of the 5G network. At this time, the terminal can also display the 4G/ Signal grid of 5G signal strength.

According to the display strategy provided by GSMA, when the terminal is dual-connected to 4G and 5G networks, the terminal only displays a network identification and signal grid, which cannot reflect the actual network connection of the terminal.

In addition, referring to Fig. 1B, in the display strategy corresponding to configuration D used by some operators (such as Vodafone), the network identification of the 5G network is displayed in both state 3 and state 4, but the 5G signal strength is displayed in state 3 In the state 4, the signal grid that characterizes the 4G signal strength is displayed. Using this display method, when the terminal is switched between state 3 and state 4, the displayed signal grid will jump, which affects the user experience.

In addition, in the initial stage of 5G commercialization, network construction requires a longer period, which may result in insufficient coverage of the 5G network for a long time. When the 4G signal is good but the 5G signal is poor, if the terminal only displays the signal grid that characterizes the 5G signal strength, it may bring unnecessary anxiety to some sensitive users.

In order to solve the shortcomings of the prior art, the embodiment of the present application provides a method for displaying a network identifier. In this method, the terminal 100 may display the network identification of the available network and the corresponding signal strength indicator on the display screen during the work flow after the power-on, so as to prompt the user of the available network. In the 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, as well as the network identifier of the 5G network and the signal strength indicator of the 5G network, respectively, according to the connection with the 4G network and the 5G network. The display of the two network identifiers does not affect each other. In this way, the actual network status of the user terminal 100 can be prompted.

In the embodiment of the present application, the network identification can be implemented as a visual interface element such as characters, icons, and text. For example, the network identifier of the 4G network may be the characters "4G", the characters "LTE", etc., and the network identifier of the 5G network may be the characters "5G", the characters "NR", and so on.

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 unit of the signal strength of the network device received by the terminal 100 may be a milliwatt decibel (dBm) or an independent signal unit (ASU). Specifically, the signal indicator of the 4G network is used to indicate the strength of the signal sent 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 sent by the network device 300 in the 5G network received by the terminal 100.

The implementation form of the signal strength indicator may be a signal grid including multiple signal bars. The more signal bars, the stronger the signal strength indicated by the signal strength indicator. The specific conversion relationship between the number of signal bars and the signal strength may be preset by the terminal 100. Not limited to the signal grid, the signal strength indicator can also be implemented in other forms, for example, it can also be an actual signal strength value (such as -50 dBm), which is not limited in the embodiment of the present application.

Subsequent embodiments will describe in detail the network identifier and the corresponding signal strength indicator displayed by the terminal 100 through the accompanying drawings, and the detailed description will not be repeated here.

In the following, the method for displaying the network identifier provided by the embodiment of the present application will be introduced in detail based on the above three dual connection modes.

(1) The display method of the network logo based on EN-DC

First, introduce the signaling process between each device when using EN-DC networking. The signaling process is formulated by 3GPP.

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

As shown in Figure 2, the signaling process may include the following processes:

1. The initial access process of the terminal 100 (UE initial access).

In the initial access process of the terminal 100, the terminal 100 first sends an RRC connection request (RRC connection request, RRC CONN REQ) to the network device 200 (for example, an eNB).

Then, the network device 200 sends RRC connection configuration signaling (RRC connection setup, RRC CONN SETUP) to the terminal. The RRC connection configuration signaling may include the frequency resources allocated to the terminal 100 by the network device 200, the coding method, and the like. In response to the RRC connection configuration signaling, the terminal 100 replies to the network device 200 with an 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 the information in the RRC configuration signaling. After the RRC connection is successfully established, the terminal 100 can exchange data with the core network through the network device 200 based on the RRC connection.

After that, the terminal 100 can transmit some access layer signaling (UL NAS TRANS) to the network device 200, and can also report wireless capability information to the core network upon the request of the network device 200 (see the capability detection signaling (UE) in Figure 2 capability enquiry, UE CAP ENQUIRE, capability information (UE capability, UE CAP)).

2. The terminal 100 performs a 5G neighbor measurement (5G neighbor measure) process.

In the 5G neighbor cell measurement, the network device 200 first sends RRC reconfiguration signaling (RRC connection 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 the RRC reconfiguration signaling may instruct the terminal 100 to measure the time and frequency 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 the first time, and the frequency point carried in the RRC reconfiguration signaling may be referred to as the first frequency point.

The terminal 100 can measure the 5G cell at the time and frequency band specified by the network device 200 according to the RRC reconfiguration signaling. After successfully measuring the 5G cell, the terminal 100 returns a 5G cell measurement report (measurement report, MEAS RPRT) to the network device 200. Here, the 5G cell measured by the terminal 100 belongs to the signal coverage area of the network device 300. The 5G cell measured by the terminal 100 means that the terminal 100 receives the signal sent by the network device 300.

3. A process in which the network device 200 adds a 5G auxiliary station (5G 5CG add) to the terminal 100.

After the terminal 100 successfully measures the 5G cell, the network device 200 sends a secondary station addition request (SgNB addition request, SgNB Addition Req) to the network device 300. After that, the network device 300 replies to the network device 200 with the auxiliary station addition confirmation (SgNB addition request acknowledgement, SgNB Addition Req ACK).

Then, the network device 200 sends RRC connection reconfiguration signaling (RRC connection reconfigration, RRC CONN RECFG) to the terminal 100 to add a secondary station (ie, the network device 300) to the terminal 100. After that, the terminal 100 restores the RRC connection reconfiguration complete signaling (RRC connection reconfigration complete, RRC CONN RECFG CMP) to the network device. After that, the network device 200 sends a secondary station addition completion signaling (secondary gNB reconfiguration complete, SgNB RECFG CMP) to the network device 300. So far, the network device 200 has successfully added a secondary station (that is, the network device 300) to the terminal 100.

After that, the terminal 100 will try to access the network device 300, that is, perform a random access process between the terminal 100 and the network device 300. After the random access process is completed, a communication link can be established between the terminal 100 and the network device 300, and the terminal 100 can exchange data with the core network through the communication link. So far, the terminal 100 has established a connection with the network device 200 and the network device 200 respectively, that is, the terminal 100 has established a dual connection. Subsequently, the terminal 100 can either perform data interaction with the core network through the network device 200, or perform data interaction with the core network through the network device 300.

It is understandable that the signaling process shown in FIG. 2 is only an example, and the detailed signaling interaction process between various devices in EN-DC can refer to the standards provided by 3GPP.

Based on the EN-DC-based signaling process shown in FIG. 2, the terminal 100 can display the network identification and the signal strength indicator corresponding to the network identification during the execution of the signaling process. The following will describe in detail the EN-DC-based network identification display method executed by the terminal 100 with reference to the accompanying drawings.

Referring to FIG. 3A, FIG. 3A shows that the terminal 100 displays the network identification of the 4G network and the start and end time of the corresponding signal strength indicator, and displays the network identification of the 5G network and the corresponding signal during the signaling process shown in FIG. 2. The start and end time of the intensity indicator.

First, introduce how the terminal 100 in the embodiment of FIG. 3A displays the network identifier of the 4G network and the corresponding signal strength indicator.

Referring to the solid gray rectangle corresponding to 4G in FIG. 3A, in some embodiments, the terminal 100 may successfully establish an RRC connection with the network device 200 for the first time after being powered on, that is, after the time point T2, it starts to display the network identification of the 4G network. The network identifier of the 4G network is used to indicate that the terminal 100 is connected to the network device 200 in the 4G network, that is, the terminal 100 can exchange data with the core network through the network device in the 4G network. In a specific implementation manner, the terminal 100 may start to display the network identification of the 4G network after replying to the network device 200 the RRC connection establishment completion signaling (RRC CONN SETUP CMP) for the first time after powering on.

Referring to the dashed gray rectangle corresponding to 4G in FIG. 3A, in some embodiments, the terminal 100 may also start to display the network identification of the 4G network when the 4G cell is measured for the first time after being turned on, that is, at the time point T1. The network identifier of the 4G network is used to indicate that the terminal 100 has measured a 4G cell. T1 is earlier than T2. The 4G cell measured by the terminal 100 means that the terminal 100 receives the signal sent by 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 identifier of the 4G network when the 4G cell cannot be measured after the second preset time period, that is, at the time point T6. The case where the terminal cannot measure the 4G cell beyond the second preset time period may include, but is not limited to: the terminal 100 enters an airplane mode or shuts down, and the terminal 100 is not within the signal coverage range of the network device 200.

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

In some embodiments, the terminal 100 may periodically measure the 4G cell and determine the measured network device 200 during the process from starting to measure the 4G cell (that is, time point T1) to when the 4G cell is not measured (that is, time point T6). When the strength of the signal sent by the network device 200 is received and the strength of the signal sent by the network device 200 changes, the signal strength indicator of the 4G network is updated. The period for the terminal 100 to measure the 4G cell may be preset and stored in the terminal 100.

Then, it is introduced how the terminal 100 in the embodiment of FIG. 3A displays the network identifier of the 5G network and the corresponding signal strength indicator.

Referring to the solid gray rectangle corresponding to 5G in FIG. 3A, in some embodiments, the terminal 100 may successfully establish a connection with the network device 300, that is, after the time point T4, start to display the network identification of the 5G network. The network identifier of the 5G network is used to indicate that the terminal 100 is connected to the network device 300 in the 5G network, that is, the terminal 100 can exchange data with the core network through the network device in the 5G network. 1A, the successful establishment of a connection between the terminal 100 and the network device 300 means that the terminal 100 successfully executes a random access process 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 to display the network identification of the 5G network after the 5G cell is measured, that is, after the time point T3. The network identifier of the 5G network is used to indicate that the terminal 100 has measured a 5G cell. T3 is earlier than T4. Referring to FIG. 2, the terminal 100 may start measuring the 5G cell after receiving the RRC reconfiguration signaling RRC CONN RECFG sent by the network device 200. Here, for the manner in which the terminal 100 measures the 5G cell, reference may be made to the related description in FIG. 1A.

In the embodiment of FIG. 3A, in some cases, the terminal 100 may stop measuring the 5G cell and stop displaying the network identifier of the 5G network at the time point T5. Time point T5 may include but is not limited to:

1. When the terminal 100 is in a connected to LTE state and has not measured a 5G cell for more than a first preset time period. Here, after the terminal 100 and the network device 200 establish an RRC connection, the terminal is in the LTE connection state before the RRC connection is disconnected or released (RRC release).

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

3. When 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 has not measured a 5G cell for more than a first preset time period. Here, after the RRC connection between the terminal 100 and the network device 200 is disconnected or released, the terminal 100 is in an idle state under LTE.

The embodiment of the application does not limit the sequence of T5 and T6. T5 may be earlier than T6, or later than T6, and may be the same as T6.

In the embodiment of FIG. 3A, in the process of displaying the network identification of the 5G network, the terminal 100 can display the signal strength indicator of the 5G network at the same time if the 5G cell is measured. The signal strength indicator of the 5G network is used to indicate the terminal 100 measured by the strength of the signal sent by the network device 300. In some embodiments, the terminal 100 may periodically measure the 5G cell and determine the measured network equipment during the process from starting to measure the 5G cell in response to the RRC reconfiguration signaling to the time when the 5G cell is not measured (ie, time point T5) The strength of the signal sent by 300, and when the strength of the signal sent by the network device 300 changes, the signal strength indicator of the 5G network is updated. 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 exemplarily shows the network identification and signal strength indicator displayed on the display screen of the terminal 100 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: a status bar 301 and an area 301. Among them, the status bar 101 includes the network identification and signal strength indicator, time indicator, battery status indicator and so on of the network. In some embodiments, the status bar 101 may also include the name of the operator, the signal strength indicator of the wireless fidelity (wireless fidelity, Wi-Fi) signal, etc., which are not limited in the embodiment of the present application. The area 102 displays application program icons (for example, an icon of a gallery, an icon of an instant messaging application "chat", an icon of a memo, etc.), a weather indicator, and the like.

As shown in Figure 3C:

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

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

At T5, 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.

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 understandable that FIG. 3C is only an example, and the signal strength indicator 301b of the 4G network displayed at different time nodes may be different to indicate 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 indicator 301d of the 5G network displayed at different time nodes may be different, and are used to indicate different signal strengths.

It is not limited to displaying the network identification and signal strength indicator in the status bar. In some other embodiments, the terminal 100 may also display the network identification and signal strength indicator in other areas of the display screen, which is not limited in the embodiment of the present application.

The network identification and signal strength indicator shown in FIG. 3C are only examples, and should not constitute a limitation to the embodiment of the present application. Not limited to characters, the network identification can also be implemented in other forms. For details, please refer to the relevant description above. Not limited to the signal grid, the signal strength indicator can also be implemented in other forms. For details, please refer to the relevant description above.

When the terminal 100 simultaneously displays the network identifier and signal strength indicator of the 4G network, and the network identifier and signal strength indicator of the 5G network in the status bar 301, it is not limited to the side-by-side display mode shown in FIG. 3C. The terminal 100 may also display in other forms. For example, referring to FIG. 3D, the terminal 100 may also display two types of network identifiers and corresponding signal strength indicators on top of each 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 overlapped and displayed, and the display colors of the two are different.

It is understandable that in the process of displaying the network identifier and the signal strength indicator by the terminal 100, the content displayed in the area 102 shown in FIG. 3C is only an example, and should not constitute a limitation to the embodiment of the present application. In addition, during this process, the content displayed in the area 102 may change with user operations, which is not limited in the embodiment of the present application.

Through the network identification scheme shown in FIG. 3A, in a network deployed with EN-DC, the terminal 100 can display the corresponding network identification and signal strength indicator according to the actual network situation, and feedback the real network situation for the user, which can improve The user experience can also facilitate users to use the services provided by the terminal 100 according to real network conditions.

Referring to FIG. 3B, FIG. 3B shows that when the terminal 100 does not successfully measure the 5G cell when performing step 2 in the signaling process shown in FIG. 2, the network identification of the 4G network and the corresponding signal strength indicator are displayed. The start and end time of the display, the network ID of the 5G network and the start and end time of the corresponding signal strength indicator.

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

In the embodiment of FIG. 3B, the manner in which the terminal 200 measures the 4G cell, the terminal 200 displays the network identifier of the 4G network and the start and end time and manner of the corresponding signal strength indicator, etc., are the same as in the embodiment in FIG. 3A, and reference may be made to related descriptions. , I won’t go into details here.

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

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, that is, when the terminal 100 fails to successfully measure the 5G cell, then The terminal 100 will not continue to perform subsequent steps in the signaling process shown in FIG. 2, such as step 3.

After the terminal 100 fails to measure the 5G cell, it can measure the 5G cell autonomously, and when the 5G cell is measured, that is, at the time point T7, it starts to display the network identity of the 5G network. The network identifier of the 5G network is used to indicate that the terminal 100 measures the signal sent by the network device 300 in the 5G network.

In some embodiments, if the terminal 100 is in the connected to LTE state when autonomously measuring 5G cells, the terminal 100 can measure the 5G cells by one or more of the following methods: no-gap measurement method, Or, specify the frequency point measurement method. After the RRC connection is established between the terminal 100 and the network device 200, the terminal 100 is in the LTE connection state before the RRC connection is disconnected or released.

In some embodiments, if the terminal 100 is in idle under LTE when autonomously measuring 5G cells, the terminal 100 can measure 5G cells by one or more of the following methods: background search method, or, Specify the frequency point measurement method.

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

The no-gap measurement mode refers to that the terminal 100 measures the 5G cell at the frequency to be measured while continuously receiving the signal sent by the network device 200. In this case, the terminal 100 does not need to configure a measurement gap, and can directly measure the 5G cell. The frequency to be tested may be the frequency specified by the network device 200 in the RRC reconfiguration signaling.

The designated frequency point measurement method refers to that the terminal 100 searches for a 5G cell on a designated frequency point, that is, receives a signal sent by the network device 300 on a 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 has camped in history, the frequency point designated by the operator stored in the SIM card installed on the terminal 100, and the frequency point where the terminal 100 currently camps on The corresponding or available 5G frequency point of the operator to which the LTE cell belongs or the frequency point searched through the background search method. In the embodiment of the present application, the designated frequency point may be referred to as the second frequency point.

In the embodiment of FIG. 3B, the terminal 100 may stop measuring the 5G cell and stop displaying the network identifier of the 5G network at the time point T8. For the time point T8, refer to the second or third case at the time point T5 in the embodiment of FIG. 3A, which is not repeated here.

In the embodiment of FIG. 3B, the terminal 100 is in the process of displaying the network identification of the 5G network, if a 5G cell is measured, the signal strength indicator of the 5G network can be displayed at the same time, and the signal strength indicator of the 5G network is used to indicate the terminal 100 measured by the strength of the signal sent by the network device 300. In some embodiments, the terminal 100 may periodically measure the 5G cell and determine the measured signal sent by the network device 300 during the process from when the terminal 100 starts to measure the 5G cell autonomously until the 5G cell is not measured (that is, the time point T8) When the strength of the signal sent by the network device 300 changes, the signal strength indicator of the 5G network is updated. 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 exemplarily shows the network identification and signal strength indicator displayed on the display screen of the terminal 100 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 may be made to related descriptions.

As shown in Figure 3E:

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

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 a network deployed with EN-DC, the terminal 100 can display the corresponding network identification and signal strength indicator according to the actual network situation, and feedback the real network situation for the user, which can improve The user experience can also facilitate users to use the services provided by the terminal 100 according to real network conditions.

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

In some embodiments, the terminal 100 may also display the signal strength indicator of the 4G network when displaying the network identification of the 4G network, and the signal strength indicator of the 4G network is used to indicate the signal sent by the network device 200 measured by the terminal 100 Strength of.

S105. The terminal 100 judges whether the 5G cell is successfully measured.

S106. In the case where the measurement operation is successful, that is, the 5G cell is measured, the terminal 100 displays the network identity of the 5G network.

S107. In the case that the measurement operation fails, that is, the 5G cell is not measured, the terminal 100 measures the 5G cell again, and displays the network identifier of the 5G network when the 5G cell is measured.
