In order to facilitate understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

With the pursuit of speed, delay, high speed mobility, energy efficiency and diversity and complexity of future life services, the third generation partnership project (3 ^rd Generation Partnership Project,3 GPP) international standards organization has begun to develop 5G for this purpose. The main application scenario of 5G is: enhanced mobile Ultra-wideband (enhanced Mobile Broadband, eMBB), low latency high reliability communications (Ultra-Reliable Low-Latency Communications, URLLC), large scale machine class communications (MASSIVE MACHINE-Type Communications, mMTC).

On the one hand eMBB still aims at obtaining multimedia content, services and data by users, and the demand for which is growing very rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., the capability and demand of which are also quite different, detailed analysis must be performed in connection with a specific deployment scenario, not in general. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety guarantee and the like. Typical features of mMTC include: high connection density, small data volume, delay insensitive traffic, low cost and long service life of the module, etc.

At early deployment of NRs, full NR coverage is difficult to acquire, so typical network coverage is wide area LTE coverage and island coverage mode of NRs. And a large amount of LTE is deployed below 6GHz, and the frequency spectrum below 6GHz which can be used for 5G is few. NR must study spectral applications above 6GHz while high-band coverage is limited and signal fading is fast. Meanwhile, in order to protect the early investment of the mobile operators in LTE, a working mode of tight coupling (tight interworking) between LTE and NR is proposed.

For the terminal equipment in the connection state, if the measurement of different frequencies or different systems is to be performed, the network side is required to configure a measurement interval, and the terminal equipment stops all services in the period of the measurement interval. Furthermore, measurement intervals may also be required for on-channel measurements.

The NR supports the measurement interval of the per UE configuration (i.e., the per-UE gap configuration) and the measurement interval of the per FR configuration (i.e., the per-FR gap configuration).

In R16, a measurement interval requirement (i.e. NeedForGap) indication information reporting mechanism is introduced, and the basic principle is that: the network side configures a band list (i.e., network side configuration NeedForGap configuration information) of indication information to be reported NeedForGap by the terminal device; the terminal equipment judges whether each band in the band list needs a measurement interval or not (namely, RRM measurement on the band or not, and whether the terminal equipment needs the measurement interval configuration or not) based on the existing radio resource configuration; the terminal device then reports a band list and indicates whether each band in the band list requires a measurement interval (i.e., the terminal device reports NeedForGap report information).

NeedForGap the configuration information is configured in an RRC reconfiguration (RRCReconfiguration) message or an RRC restore (RRCResume) message, however, at present, release of NeedForGap the configuration information can only release all NeedForGap configuration information on the terminal device side at one time, and the network side can only instruct the terminal device to release NeedForGap configuration information or establish NeedForGap configuration information, which cannot achieve release NeedForGap configuration information and establish NeedForGap configuration information simultaneously. For this reason, the following technical solutions of the embodiments of the present application are provided.

Fig. 2 is a flow chart of a method for releasing configuration according to an embodiment of the present application, as shown in fig. 2, where the method for releasing configuration includes the following steps:

Step 201: the terminal device receives first indication information and first NeedForGap configuration information sent by the network device, where the first indication information is used to instruct the terminal device to release the second NeedForGap configuration information.

In the embodiment of the application, the network device sends the first indication information and the first NeedForGap configuration information to the terminal device, and correspondingly, the terminal device receives the first indication information and the first NeedForGap configuration information sent by the network device. In an alternative, the network device may be a base station, such as a gNB.

In the embodiment of the present application, the terminal device may receive the first indication information and the first NeedForGap configuration information sent by the network device in any one of the following manners.

Mode one: the network device sends a first RRC message to the terminal device, and correspondingly, the terminal device receives the first RRC message sent by the network device, wherein the first RRC message carries first indication information and first NeedForGap configuration information. Further optionally, the first RRC message is an RRC reconfiguration message or an RRC recovery message.

Mode two: the network device sends a first RRC message to the terminal device, and accordingly, the terminal device receives the first RRC message sent by the network device, wherein the first RRC message carries first NeedForGap configuration information, and the first NeedForGap configuration information carries first indication information. Further optionally, the first RRC message is an RRC reconfiguration message or an RRC recovery message.

Step 202: the terminal device releases the second NeedForGap configuration information and establishes the first NeedForGap configuration information.

In the embodiment of the application, the terminal device can release the second NeedForGap configuration information and establish new first NeedForGap configuration information simultaneously through the first indication information and the first NeedForGap configuration information.

● In an alternative manner, the first indication information is used to instruct the terminal device to release all the NeedForGap configuration information, where the terminal device releases all the NeedForGap configuration information, and establish the first NeedForGap configuration information.

For example: the first indication information is 1bit indication information, and a value of 1bit indication information is 1 to indicate that all NeedForGap configuration information is released.

● In an optional manner, the first indication information is used to instruct the terminal device to release the first portion NeedForGap of the configuration information, the terminal device releases the first portion NeedForGap of the configuration information, and reserves the second portion NeedForGap of the configuration information; the terminal device superimposes the first NeedForGap configuration information on the second part NeedForGap of configuration information.

In an alternative, the first indication information includes a band list (i.e., identification information of one or more bands).

For example: the band list configured by the current NeedForGap configuration information of the terminal device includes: band1, band2, band3 and band4. The first indication information indicates that the band1 and the band3, and the band list configured by the new NeedForGap configuration information (i.e., the first NeedForGap configuration information) includes: band5. Then, the terminal device determines that the final band list configured by NeedForGap configuration information includes: band2, band4 and band5.

In one example, the network device adds first indication information (e.g., 1bit indication information) in the RRC reconfiguration message or the RRC restore message or the first NeedForGap configuration information, where the first indication information is used to instruct the terminal device to release all NeedForGap configuration information. Meanwhile, the RRC reconfiguration message or the RRC recovery message carries first NeedForGap configuration information, which is used for establishing new NeedForGap configuration information. After the terminal device receives the two information (i.e., the first indication information and the first NeedForGap configuration information) at the same time, it first performs releasing all NeedForGap configuration information, and then establishes new NeedForGap configuration information (i.e., the first NeedForGap configuration information).

In one example, the network device adds first indication information in the RRC reconfiguration message or RRC recovery message or first NeedForGap configuration information, which is used to indicate the terminal device release portion NeedForGap configuration information (e.g., the first portion NeedForGap configuration information). Meanwhile, the RRC reconfiguration message or the RRC recovery message carries first NeedForGap configuration information, which is used for establishing new NeedForGap configuration information. After the terminal device receives the two information (i.e. the first indication information and the first NeedForGap configuration information) at the same time, the terminal device first performs releasing the first portion NeedForGap configuration information, and then superimposes new NeedForGap configuration information (i.e. the first NeedForGap configuration information) on the remaining second portion NeedForGap configuration information as the last NeedForGap configuration information.

In the above scheme, needForGap configuration information (such as the first NeedForGap configuration information or the second NeedForGap configuration information) may be implemented by a "NeedForGapsConfigNR" cell, and the content of the "NeedForGapsConfigNR" cell is shown in the following table 1:

TABLE 1

In the embodiment of the present application, needForGap (from terminal equipment reporting) reporting information stored on the network equipment side may be updated, which is described below.

● In an alternative manner, the terminal device sends a first NeedForGap report message to the network device, where the first NeedForGap report message is used to instruct all NeedForGap report messages before the network device releases the report messages, and stores the first NeedForGap report message.

For a network device, the network device receives first NeedForGap report information sent by the terminal device; and the network equipment releases all NeedForGap reported information before releasing and stores the first NeedForGap reported information.

Specifically, the terminal device sends a second RRC message to the network device, and accordingly, the network device receives the second RRC message sent by the terminal device, where the second RRC message carries the first NeedForGap reporting information. Further optionally, the second RRC message is an RRC reconfiguration complete message or an RRC recovery complete message.

In one example, the terminal device sends an RRC reconfiguration complete message or an RRC recovery complete message to the network device, and if the RRC reconfiguration complete message or the RRC recovery complete message includes the first NeedForGap report information, the base station deletes all NeedForGap report information before, and the new NeedForGap report information (i.e., the first NeedForGap report information) completely replaces the old NeedForGap report information.

● In an optional manner, the terminal device sends first NeedForGap report information and second instruction information to the network device, where the second instruction information is used to instruct all NeedForGap report information or part NeedForGap report information before the network device releases the report information, and stores the first NeedForGap report information.

For a network device, the network device receives first NeedForGap report information and second instruction information sent by the terminal device, where the second instruction information is used to instruct all NeedForGap report information or part NeedForGap report information before the network device releases the report information; the network device releases all NeedForGap or part NeedForGap of the previous report information and stores the first NeedForGap report information.

Specifically, mode one: and the terminal equipment sends a second RRC message to the network equipment, and correspondingly, the network equipment receives the second RRC message sent by the terminal equipment, wherein the second RRC message carries the first NeedForGap reporting information and the second indicating information. Or the mode II: the terminal device sends a second RRC message to the network device, and accordingly, the network device receives the second RRC message sent by the terminal device, where the second RRC message carries first NeedForGap report information, and the first NeedForGap report information carries second indication information. Further optionally, the second RRC message is an RRC reconfiguration complete message or an RRC recovery complete message.

In one example, the terminal device sends an RRC reconfiguration complete message or an RRC recovery complete message to the network device, where the RRC reconfiguration complete message or the RRC recovery complete message includes first NeedForGap report information, and the first NeedForGap report information carries second indication information.

1) In an alternative manner, the second indication information is used to instruct all NeedForGap of the reporting information before the network device is released.

For example: the second indication information is 1bit indication information, and the 1bit indication information is used for indicating all NeedForGap reporting information before release.

2) In an alternative manner, the second indication information is used to instruct all NeedForGap of the reporting information before the network device is released. Specifically, the second indication information includes at least one of:

The first sub-information is used for indicating a first part NeedForGap before the network equipment is released to report information;

Second sub-information, the second sub-information is used for indicating a second part NeedForGap before the network equipment is released to report information;

Wherein, the first part NeedForGap reports NeedForGap reports all different frequencies (inter-frequency), and the second part NeedForGap reports NeedForGap reports all same frequencies (intra-frequency).

For example: the second indication information is 2bit indication information, one bit indication information is used for indicating all NeedForGap reporting information of inter-frequency before release, and the other bit indication information is used for indicating all NeedForGap reporting information of intra-frequency before release.

3) In another alternative, the second indication information is used to instruct the part NeedForGap before the network device releases to report information. Specifically, the second indication information includes at least one of:

Third sub-information, where the third sub-information is used to instruct the third portion NeedForGap before the network device releases the information to report;

a fourth sub-information, where the fourth sub-information is used to instruct the fourth portion NeedForGap before the network device is released to report information;

Wherein, the third part NeedForGap reports NeedForGap reporting information of the inter-frequency of the information finger part, and the fourth part NeedForGap reports NeedForGap reporting information of the intra-frequency of the information finger part.

In the above solution, optionally, the third sub-information includes identification information of one or more frequency bands.

In the above solution, optionally, the fourth sub-information includes serving cell identification information of one or more cells.

For example: the third sub-information is used for indicating a part NeedForGap of the inter-frequency report information before release, and the released NeedForGap report information is identified by a band indicator; the fourth sub-information is used to indicate NeedForGap reporting information of intra-frequency before release, and the released NeedForGap reporting information is identified by a serving cell identification (SERVCELLID).

In the above scheme, needForGap reporting information (such as the first NeedForGap reporting information) may be implemented by a "needForGapsInfoNR" cell, and the content of the "needForGapsInfoNR" cell is shown in the following table 2:

TABLE 2

In the embodiment of the present application, in the handover scenario, the first NeedForGap may need to re-report the information. Specifically, if the terminal device receives a handover command within a first time period after sending the first NeedForGap report information, the terminal device resends the first NeedForGap report information to the target cell after switching to the target cell. Or if the terminal equipment is triggered to send the first NeedForGap reporting information and receives a switching command in a first time period, after switching to a target cell, the terminal equipment resends the first NeedForGap reporting information to the target cell. Here, optionally, the first duration is configured by a network device or agreed by a protocol. For example: the first duration is 1s.

The technical solution of the embodiment provides a method for simultaneously releasing and establishing NeedForGap configuration information, and also provides a method for simultaneously releasing NeedForGap configuration information and adding new NeedForGap configuration information. In addition, an updating mode of NeedForGap reporting information and a method for timely reporting NeedForGap reporting information in the switching process are also provided.
