Technical field

This application relates to the field of communication technology, and in particular to a method and device for configuring terminal equipment.

Background technique

Cell handover across base stations means that when a terminal device moves from the coverage area of one base station (source base station) to the coverage area of another base station (target base station), the original communication connection of the terminal device will be changed and transferred to another base station. A communication connection, so that the terminal device continues to maintain a communication connection with the base station. Before the terminal device performs cell handover, the source base station will issue configuration information to the terminal device, for example, called configuration information 1. The configuration information 1 may include one or more information elements (IE), and the configuration information 1 is for the terminal The device communicates under the source base station. During the cell handover process, the source base station will send configuration information 1 to the target base station. During the cell handover process, the target base station will also send configuration information to the terminal device (forwarded by the source base station), for example, called configuration information 2. The configuration information 2 may include one or more IEs, and the configuration information 2 is used for the terminal device For communication under the target base station, the configuration information 2 may be determined according to the configuration information 1. After the terminal device switches to the target base station, the configuration information 2 can be applied.

The communication version supported by each base station may be different, so the communication version of the source base station and the target base station may be different. For example, the communication version of the source base station may be higher than the communication version of the target base station. Since the base station of the higher version supports more functions than the base station of the lower version, the base station of the higher version can be configured with more IEs, but the base station of the lower version cannot recognize the IE corresponding to the new function because it does not have new functions. Since the target base station cannot recognize these IEs, it will not send these IEs to the terminal device. However, the characteristic of some IEs is that if the terminal device received the IE last time, but did not receive the IE this time, it indicates that the terminal device needs to continue to apply the configuration corresponding to the IE received last time. Therefore, for this type of IE, if the terminal device determines that the source base station has sent the IE to the terminal device, but the target base station has not sent the IE to the terminal device, the terminal device will continue to use the configuration corresponding to the IE from the source base station. However, the target base station cannot recognize the IE, and naturally cannot support the configuration corresponding to the IE, which may cause the terminal device to fail to communicate normally under the target base station.

Summary of the invention

The embodiments of the present application provide a method and device for configuring a terminal device, which are used to make the IE applied by the terminal device and the network device consistent, and to ensure the normal communication of the terminal device under the network device.

In a first aspect, a first method for configuring a terminal device is provided. The method includes: before a cell handover, determining first configuration information of a first network device, where the first network device is a source for the terminal device to perform the cell handover Network equipment; in the cell handover process, receiving second configuration information from a second network equipment, where the second network equipment is the terminal device for the target network equipment for the cell handover; determining the first configuration The information includes a first field, and the second configuration information does not include the first field, where the first field is when the second configuration information received by the terminal device does not include the first field , The terminal device needs to keep the field of the content of the first field received last time; release the configuration corresponding to the first field included in the first configuration information.

The method may be executed by a first communication device, and the first communication device may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the first communication device is a terminal device, or a chip set in the terminal device for realizing the function of the terminal device, or other component used for realizing the function of the terminal device. In the following introduction process, it is taken as an example that the first communication device is a terminal device.

For example, the first field is a field that needs to be inherited, that is, if the terminal device received the first field last time, but did not receive the first field this time, the terminal device needs to continue to apply the configuration corresponding to the first field received last time. In this embodiment of the application, if the terminal device determines that the first configuration information from the first network device includes the first field, and the first configuration information from the target network device does not include the first field, the terminal device can release the first field. The configuration corresponding to the first field included in the configuration information, that is, the terminal device no longer applies the previously received configuration corresponding to the first field. The second network device did not send the first field to the terminal device. It is probably because the second network device cannot recognize the first field. Therefore, the terminal device releases the configuration corresponding to the first field, which can make the terminal device and the second network device apply The fields are kept consistent, so that the terminal device can communicate normally under the second network device.

With reference to the first aspect, in a first optional implementation manner of the first aspect, the first field includes overheating configuration information.

The overheating configuration information can configure the terminal device to send overheat-related information to the network device, or configure the terminal device not to send overheat-related information to the network device.

With reference to the first optional implementation manner of the first aspect, in a second optional implementation manner of the first aspect, the overheating configuration information includes:

First indication information, where the first indication information is used to indicate whether auxiliary information related to overheating can be sent to the network device; and/or,

The timing duration of the prohibition timer, wherein, within the running time of the prohibition timer, the terminal device cannot send auxiliary information related to overheating to the network device.

For example, if the overheating configuration information includes the first indication information, and the first indication information indicates that the auxiliary information related to overheating cannot be sent to the network device, the terminal device does not send the auxiliary information related to overheating to the network device. For another example, if the overheating configuration information includes the first indication information and the timing duration of the prohibition timer, and the first indication information indicates that the auxiliary information related to overheating can be sent to the network device, the terminal device may send the auxiliary information related to overheating to the network device When sending the auxiliary information related to overheating or after sending the auxiliary information related to overheating, the terminal device starts the prohibition timer. Similarly, the network device receives the auxiliary information related to overheating or when receiving the auxiliary information related to overheating. After that, the prohibit timer is also started. During the running time of the prohibition timer, the terminal device cannot send the auxiliary information related to overheating to the network device, and the terminal device can only send the auxiliary information related to the overheating to the network device when the prohibition timer expires or after the timeout. For another example, if the overheating configuration information includes the first indication information, and the first indication information indicates that the auxiliary information related to overheating can be sent to the network device, and the overheating configuration information does not include the timing duration of the prohibition timer, the terminal device may be required It sends auxiliary information related to overheating to the network device at any time.

With reference to the second optional implementation manner of the first aspect, in a third optional implementation manner of the first aspect, the auxiliary information related to overheating includes one or more of the following:

The maximum number of uplink secondary carriers or the maximum number of uplink secondary cells supported by the terminal equipment;

The maximum number of downlink secondary carriers or the maximum number of downlink secondary cells supported by the terminal device;

The maximum uplink aggregate bandwidth that the terminal device can support in each supported frequency band;

The maximum downlink aggregate bandwidth that the terminal device can support in each supported frequency band;

The maximum number of uplink MIMO layers that the terminal device can support in each supported frequency band;

The maximum number of downlink MIMO layers that the terminal device can support in each supported frequency band; or,

Type information of the terminal device.

For example, the auxiliary information related to overheating may include the maximum number of uplink auxiliary carriers supported by the terminal device; or, the auxiliary information related to overheating may include the maximum number of auxiliary cells in the downlink supported by the terminal device; or, the auxiliary information related to overheating may include the terminal device's The maximum uplink aggregate bandwidth that each supported frequency band can support, and the maximum downlink aggregate bandwidth that the terminal device can support in each supported frequency band; or, the auxiliary information related to overheating may include the maximum aggregate bandwidth supported by the terminal device in each frequency band supported. The maximum downlink aggregate bandwidth that can be supported by each frequency band, the maximum number of uplink MIMO layers that can be supported by each serving cell of each frequency band supported by the terminal device, and the type information of the terminal device; or, auxiliary information related to overheating It can include the maximum number of uplink auxiliary carriers or the maximum number of uplink auxiliary cells supported by the terminal device, the maximum number of downlink auxiliary carriers or the maximum number of downlink auxiliary cells supported by the terminal device, and the maximum uplink aggregation that the terminal device can support in each supported frequency band Bandwidth, the maximum downlink aggregate bandwidth that the terminal device can support in each supported frequency band, the maximum number of uplink MIMO layers that each serving cell of each supported frequency band of the terminal device can support, and the maximum number of uplink MIMO layers supported by the terminal device in each frequency band supported. The maximum number of downlink MIMO layers that can be supported by each serving cell on each supported frequency band, and so on. The configuration indicated by the auxiliary information related to overheating (which can be understood as the value of the parameter included in the auxiliary information related to overheating) is the configuration expected by the terminal device, rather than the configuration that can be actually supported by the capabilities of the terminal device, for example , The configuration indicated by the auxiliary information related to overheating may be lower than or equal to the configuration actually supported by the capabilities of the terminal device. It can be understood that if the terminal device applies the configuration indicated by the auxiliary information related to overheating, the overheating of the terminal device can be improved.

Combining the first aspect or the first optional implementation manner of the first aspect to any optional implementation manner of the third optional implementation manner of the first aspect, the fourth aspect of the first aspect may be In an optional implementation manner, before releasing the first field included in the first configuration information, the method further includes:

It is determined that the second configuration information does not include the field corresponding to the first version, and does not include the field corresponding to any version higher than the first version, and the first version is the communication version corresponding to the first field .

For each of the one or more fields included in the first configuration information but not included in the second configuration information, the terminal device can determine the demand code corresponding to the field, and if the demand code corresponding to the field indicates that the field needs to be inherited For example, the first field is a field that needs to be inherited. For example, the demand code corresponding to the first field is need M. For such a field, the terminal device can release the configuration corresponding to the field included in the first configuration information, that is, the terminal The device will not continue to apply the configuration corresponding to the field included in the first configuration information. In this way, the terminal device does not need to determine the communication version corresponding to the field, as long as a field is included in the first configuration information and not included in the second configuration information, and the field is a field that needs to be inherited, the terminal device can The configuration corresponding to the field included in the first configuration information is released, so that the terminal device no longer applies the configuration corresponding to the field included in the first configuration information.

Alternatively, in the embodiment of the present application, the terminal device may also determine the communication version corresponding to the field, and then perform corresponding processing. For example, for each field in one or more fields that are included in the first configuration information but not included in the second configuration information, the terminal device may determine the demand code corresponding to the field, and if the demand code corresponding to the field indicates that the field is required Inherited fields, for example, the first field is the field that needs to be inherited. For example, the demand code corresponding to the first field is need M, and the communication version corresponding to the first field is the first version. For the first field, the terminal device can further determine , Whether the second configuration information includes other fields corresponding to the first version, or determine whether the second configuration information includes other fields corresponding to any version higher than the first version, or determine whether the second configuration information includes the first version Other fields corresponding to the version, and determining whether the second configuration information includes other fields corresponding to any version higher than the first version. If the second configuration information includes other fields corresponding to the first version, or includes other fields corresponding to any version higher than the first version, or includes other fields corresponding to the first version and includes any other fields higher than the first version Version corresponding to other fields, then the terminal device can determine that the second network device can support the first version corresponding to the first field. The reason why the second configuration information does not include the first field may be that the second network device thinks that the terminal device needs Continue to apply the configuration corresponding to the first field included in the first configuration information. Therefore, in this case, the terminal device does not need to release the content of the first field included in the first configuration information, but can continue to apply the configuration corresponding to the first field included in the first configuration information. By determining the version, the terminal device can try not to release the content included in the fields that the second network device can support, so that the configuration of the terminal device and the second network device are consistent, and ensure that the terminal device can perform normally under the second network device. data communication.

Combining the first aspect or the first optional implementation manner of the first aspect to any optional implementation manner of the fourth optional implementation manner of the first aspect, the fifth aspect of the first aspect may be In an optional embodiment, the method further includes:

The capability of the terminal device is adjusted from a first capability to a second capability, where the first capability is lower than the second capability, and the first capability is that the first network device is adapted to the second capability. The content of a field is configured.

For example, if the first network device receives the auxiliary information related to overheating from the terminal device, the first network device can decide whether to reduce the air interface configuration of the terminal device, so as to alleviate the overheating problem of the terminal device. If the first network device decides to reduce the air interface configuration of the terminal device, the first network device may determine the air interface configuration information according to the received auxiliary information related to overheating, and include the air interface configuration information in the RRC reconfiguration message and send it to the terminal device. After receiving the air interface configuration information, the terminal device can apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before the air interface configuration is reduced, the capability of the terminal device is the second capability, and after the air interface configuration is reduced, the capability of the terminal device is the first capability, and the first capability is lower than the second capability. If the terminal device needs to switch to the second network device, the second network device may not support the communication version corresponding to the first field, that is, the target network device cannot recognize the first field, so the second network device naturally cannot learn about the terminal device. The ability is adjusted according to the first field. Therefore, the terminal device can adjust the capability of the terminal device back to the second capability, so that the second network device can schedule the terminal device according to the second capability, reducing the ability of the terminal device and the actual application of the terminal device as understood by the second network device. The probability of scheduling errors caused by inconsistent capabilities.

In a second aspect, a second method for configuring a terminal device is provided, the method comprising: determining that the second version is lower than the first version, the first version is the communication version of the first network device, and the second version is the second version. The communication version corresponding to the network device, the first network device is the source network device for the terminal device to perform cell handover, and the second network device is the target network device for the terminal device to perform the cell handover; to the terminal device Send first information, the first information is used to indicate the release of the configuration corresponding to the first field, where the first field is when the configuration information received by the terminal device does not include the first field, the terminal The device needs to keep the field of the content of the first field received last time; send a switching command to the terminal device, where the switching command is used to instruct to switch from the first network device to the second network device.

The method may be executed by a second communication device, and the second communication device may be a communication device or a communication device capable of supporting the communication device to implement the functions required by the method, such as a chip. Exemplarily, the second communication device is a network device, or a chip set in the network device for realizing the function of the network device, or other component used for realizing the function of the network device. In the following introduction process, it is assumed that the second communication device is a network device, for example, the first network device. Exemplarily, the first network device is an access network device.

In the embodiment of the present application, if the first network device determines that the communication version of the second network device is lower than the communication version of the first network device, it can instruct the terminal device to release all or part of the configuration corresponding to the fields that need to be inherited. In this way, the terminal The device no longer applies the configuration corresponding to these fields previously received. In this way, the application fields of the terminal device and the target network device can be kept consistent, so that the terminal device can communicate normally under the target network device.

With reference to the second aspect, in a first optional implementation manner of the second aspect, the first field corresponds to the first version, or corresponds to the difference between the first version and the second version Other versions of.

Because the communication version of the second network device is the second version, no matter the fields corresponding to the second version or the fields corresponding to other versions lower than the second version, the second network device can support. If the first network device includes these fields in the configuration information and sends it to the second network device, the second network device can be identified and can also make further configurations based on these fields. Therefore, in this way, the first network device needs to determine the specific version of the second network device, and also the version corresponding to the field. The first network device just instructs the terminal device to release the field corresponding to the first version, and release the field corresponding to the first version. Fields of other versions between the first version and the second version, but there is no need to release the fields corresponding to the second version, and there is no need to release the fields corresponding to other versions lower than the second version. This can also make the second network device and the terminal device have consistent understanding of the configuration information, and the terminal device needs to release fewer fields, which can reduce the workload of the terminal device. Moreover, for these unreleased fields that can be recognized by the second network device, the second network device can also perform further configuration, which helps reduce the workload of the second network device.

With reference to the second aspect or the first optional implementation manner of the second aspect, in a second optional implementation manner of the second aspect, the first information is used to indicate the release of the configuration corresponding to the first field, including :

The first information includes the first field, and the content of the first field is used to indicate the release of the configuration corresponding to the first field; or,

The first information is first indication information, the first indication information is used to indicate the release of the configuration corresponding to one or more fields, the one or more fields include the first field, and the one or more fields Each field in the field is a field in which the terminal device needs to keep the content of the field received last time when the configuration information received by the terminal device does not include the field.

For example, the first information may be configuration information. The first content may indicate the release of the corresponding field. For example, if the configuration information previously configured for the terminal device by the first network device includes the first field, the first information also includes the first field, and the content of the first field is the first content, and the first content is used to indicate the release of the first field The corresponding configuration, in other words, is used to indicate the release of the content of the first field. Then after the terminal device receives the first information, according to the first content included in the first field, the terminal device side will release the content of the first field included in the configuration information from the first network device previously stored on the terminal device side, so as not to continue. The configuration corresponding to the first field included in the configuration information is applied. In this implementation manner, it is equivalent to the first network device resending new configuration information to the terminal device to instruct to release all or part of the fields that need to be inherited included in the original configuration information. This indication method is relatively clear for the terminal device, and the terminal device can determine which fields need to be released according to the fields included in the first information.

Alternatively, the first information may be indication information, for example called first indication information, and the first indication information may occupy one or more bits. The first indication information may indicate to release the configuration corresponding to one or more fields, and the first field is, for example, one of the one or more fields. These one or more fields are all fields that need to be inherited. These one or more fields are all or part of the fields that need to be inherited included in the configuration information previously configured for the terminal device by the first network device, that is, the first indication The information is used to indicate the release of all or part of the fields that need to be inherited included in the configuration information. After the terminal device receives the first indication information, it can release all or part of the content of the fields that need to be inherited included in the configuration information from the first network device stored on the terminal device side, so that the configuration information included in the configuration information is no longer applied. The configuration corresponding to these fields. For example, the field released by the terminal device includes the first field. In this implementation manner, the first network device does not need to re-send new configuration information to the terminal device, but only needs to send the first instruction information to the terminal device to instruct the release of the corresponding field. Compared with the configuration information, the information amount of the first indication information is small, which helps to save transmission overhead.

In combination with the second aspect or the first optional implementation manner of the second aspect or the second optional implementation manner of the second aspect, in the third optional implementation manner of the second aspect, the method further include:

Sending first configuration information to the second network device, where the first configuration information includes a field configured by the first network device for the terminal device, and the first configuration information does not include the first field.

For example, the first network device may obtain the first configuration information according to the configuration information previously configured to the terminal device by the first network device. For example, the first network device deletes all or part of the fields that need to be inherited from the configuration information previously configured for the terminal device, and the configuration information obtained thereby may be the first configuration information. These fields deleted by the first network device from the configuration information previously configured for the terminal device are the fields that the first network device instructs the terminal device to release. After obtaining the first configuration information, the second network device can configure the terminal device according to the first configuration information. Since the first configuration information does not include fields that need to be inherited that the second network device cannot recognize, the second network device can configure the terminal device normally.

In combination with the second aspect or the first optional implementation manner of the second aspect or the second optional implementation manner of the second aspect, in the third optional implementation manner of the second aspect,

In the embodiment of the present application, the configuration mode applied by the second network device is the inheritance configuration mode, or iterative configuration mode, that is, the next configuration needs to be performed based on the previous configuration, for example, based on the first configuration. The first configuration information of the network device determines the second configuration information, that is, the second configuration information is not configured in a full configuration manner. In practical applications, the second network device may also adopt a full configuration mode, which is a mode in which all fields to be configured to the terminal device are reconfigured. Regarding the full configuration mode, reference may be made to the related introduction of the embodiment shown in FIG. 5. The embodiment of this application does not limit the configuration method adopted by the second network device, but if the second network device adopts the full configuration method, for the first network device, there is no need to instruct the terminal device to release the fields that need to be inherited . Therefore, as an optional implementation manner, the second network device may send configuration instruction information to the first network device, and the first network device may receive configuration instruction information from the second network device. The configuration instruction information may indicate that the second network device has not configured the terminal device in a full configuration mode, so that the first network device can perform subsequent related operations.

Regarding the technical effects brought about by some implementations of the second aspect, reference may be made to the introduction of the technical effects of the corresponding implementations of the first aspect.

Or the degree of importance is different.

The foregoing introduces some terms and concepts involved in the embodiments of the present application, and the technical features involved in the embodiments of the present application are introduced below.

After the terminal device is connected to the network device, the network device needs to issue a wireless access configuration to the terminal device, and the terminal device applies the configuration issued by the network device, so that the terminal device can perform data communication normally under the network device. Please refer to Figure 1 for the flow chart of configuring terminal devices for network devices.

S11. The network device sends a configuration message to the terminal device, and correspondingly, the terminal device receives the configuration message from the network device.

Exemplarily, the configuration message may be a radio resource control (radio resource control, RRC) reconfiguration (RRC reconfiguration) message, or an RRC setup (RRC setup) message, or an RRC reestablishment (RRC reestablishment) message, or RRC resume (RRC resume) messages, etc. The configuration message may include the parameters configured by the network device for the terminal device. For example, the configured parameters may include: radio bearer configuration parameters, physical layer (PHY) parameters, medium access control layer (medium access control, One or more of MAC) parameters, radio link control (RLC) parameters, or security parameters.

Among them, the network device may send configuration messages to the terminal device multiple times. Therefore, the configuration message sent at a certain time can be further configured based on the previous configuration message, that is, the network device adopts a relative configuration (delta configuration) The way. Specifically, the configuration message may include one or more IEs, each IE is a field or a field, and an IE may be understood as a parameter, or it may be understood as an IE including a parameter. In the configuration message, each IE can correspond to corresponding need codes, and the need codes corresponding to different IEs may be the same or different. For the requirement code, please refer to the introduction in Table 1.

Table 1

Table 1 lists 4 kinds of demand codes. For example, if the requirement code corresponding to a field is the requirement code R (ie, need R), then this field is a field that needs to be inherited, and the parameters configured through this field can be regarded as non-one-time parameters. That is, if the terminal device previously received the field, but did not receive the field this time, the terminal device needs to release the configuration corresponding to the field previously received, that is, the terminal device will not continue to apply the configuration corresponding to the field previously received . And if the terminal device has received this field before, and this field is also received this time, the terminal device needs to apply the configuration corresponding to the field received this time.

For another example, if the demand code corresponding to a field is the demand code M (ie, need M), the field is the field that needs to be inherited, and the parameters configured through the field can be considered as non-one-time parameters. That is, if the terminal device previously received this field, but did not receive this field this time, the terminal device needs to continue to apply the configuration corresponding to the field received before, that is, it needs to continue to apply the parameters included in the previously received field. And if the terminal device has received this field before, and this field is also received this time, the terminal device needs to apply the configuration corresponding to the field received this time.

For example, the network device first sends configuration message 1 to the terminal device. Configuration message 1 includes IE1, IE2, and IE3, where the demand code corresponding to IE1 is needM, and the demand code corresponding to IE2 and IE3 are both needR, then the terminal equipment Apply the configuration corresponding to IE1, the configuration corresponding to IE2, and the configuration corresponding to IE3. After that, the network device sends a configuration message 2 to the terminal device, and the configuration message 2 is further configured according to the configuration message 1. For example, the configuration message 2 includes IE2 and IE4, and the demand code corresponding to IE4 is the demand code N. Because configuration message 2 is re-issued with IE2, the terminal device applies the configuration corresponding to IE2 included in configuration message 2, and if IE4 is newly issued in configuration message 2, the terminal device applies the configuration corresponding to IE4 included in configuration message 2. . In addition, configuration message 2 does not include IE1, but configuration message 1 includes IE1, and the demand code corresponding to IE1 is need M. Therefore, the terminal device continues to apply the configuration corresponding to IE1 included in configuration message 1. The configuration message 2 does not include IE3, and the demand code corresponding to IE3 is need R. Therefore, the terminal device releases the configuration corresponding to IE3 included in the configuration message 1, that is, the terminal device does not apply the configuration corresponding to IE3 included in the configuration message 1.

S12. The terminal device applies the configuration included in the configuration message. According to this configuration, the terminal device can perform data communication normally under the current network device.

In addition, the terminal device may overheat during use. Then, when the terminal device has an overheating problem inside the device, the temperature of the terminal device can be reduced by reducing the capacity or configuration of the terminal device to solve the overheating problem. In order to reduce the capability or configuration of the terminal device, the terminal device can send UE assistance information to the network device. The UE assistance information is overheating assistance information to notify the network device of the expected reduced capability or configuration of the terminal device for the network device. Device reference for reconfiguration. In order for a terminal device to send UE auxiliary information to the network device, the network device needs to send the overheating configuration information to the terminal device first, so that the terminal device can send the UE auxiliary information to the network device. The overheating configuration information sent by the network device to the terminal device may be included in the configuration message sent by the network device to the terminal device, such as the configuration message shown in S11 in the process shown in FIG. 1. Please refer to FIG. 2 below to introduce the process of sending UE auxiliary information from a terminal device to a network device.

S21. The network device sends an RRC reconfiguration message to the terminal device, and the terminal device receives the RRC reconfiguration message from the network device.

The RRC reconfiguration message may be understood as a configuration message, and the RRC reconfiguration message may include overheating configuration information. The overheating configuration information includes, for example, information used to indicate whether the terminal device can send overheating auxiliary information to the network device, and the value of a prohibition timer related to overheating. Among them, the prohibition timer is used by the network device to control the frequency of the terminal device reporting the overheating auxiliary information. After the terminal device reports the overheating auxiliary information once, the terminal device and the network device need to start the prohibition timer synchronously. During the process, the terminal device cannot report the auxiliary overheating information again, and can only report the auxiliary overheating information again when or after the prohibition timer expires. The value of the prohibit timer specified in the existing agreement can be selected in a range, which is {s0,s0dot5,s1,s2,s5,s10,s20,s30,s60,s90,s120,s300,s600, spare3,spare2,spare1}, where s means the unit is seconds, for example, s0 means 0 seconds, s1 means 1 second. s0dot5 means 0.5 seconds, and spare means reserved bits. For example, spare3, spare2, and spare mean three reserved bits.

Wherein, the overheating configuration information sent by the network device to the terminal device may be included in one or more IEs, and the demand code corresponding to the one or more IEs may be needM.

S22. The terminal device sends the auxiliary overheating information to the network device, and the network device receives the auxiliary overheating information from the terminal device.

If the overheating configuration information sent by the network device is used to configure the terminal device to be able to send the auxiliary information related to overheating, then when the terminal device has an overheating problem, the terminal device can send the overheating auxiliary information to the network device. Or, if the overheating configuration information sent by the network device is used to configure the terminal device to be able to send overheat-related auxiliary information, then when the terminal device has an overheating problem and the prohibit timer is not running, the terminal device can send overheating assistance to the network device information. For example, the terminal device may include the overheating assistance information in the UE assistance information message and send it to the network device.

In scenarios such as NR independent networking, NR-DC, or NE-DC, the overheating assistance information that a terminal device can report may include one or more of the following: The maximum uplink secondary carrier supported by the terminal device (component carrier, The number of CC) or the maximum number of uplink secondary cells (secondary cells, SCell), the maximum number of downlink secondary carriers or the maximum number of downlink secondary cells supported by the terminal device, the maximum uplink aggregate bandwidth that the terminal device can support in each frequency band supported, The maximum downlink aggregate bandwidth that a terminal device can support in each supported frequency band, the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device in each frequency band supported, or the terminal device The maximum number of downlink MIMO layers that can be supported by each serving cell on each supported frequency band. In scenarios such as (NG)EN-DC, the overheating assistance information that the terminal device can report includes: the type of the terminal device (UE category), and/or the number of MIMO layers supported by the terminal device.

S23. The network device sends an RRC reconfiguration message to the terminal device, and the terminal device receives the RRC reconfiguration message from the network device.

If the network device receives the overheating auxiliary information from the terminal device, the network device can decide whether to reduce the air interface configuration of the terminal device, thereby alleviating the overheating problem of the terminal device. As for how to make a decision, it depends on the internal implementation of the network equipment. If the network device decides to reduce the air interface configuration of the terminal device, the network device can determine the configuration information according to the received overheating auxiliary information, and include the configuration information in the RRC reconfiguration message and send it to the terminal device. The terminal device can reduce the configuration information by applying the configuration information. The air interface configuration of the terminal device. After the terminal device uses the reduced air interface configuration for communication, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the problem of overheating.

Since some terminal devices are in a mobile state, such as mobile phones and other terminal devices, the terminal devices will be involved in cell handover. Cell handover can include cell handover within a base station and cell handover across base stations. Inter-base station cell handover refers to when a terminal device moves from the coverage area of one base station (source base station) to the coverage area of another base station (target base station). The original communication connection of the terminal device will be changed and switched to another communication connection, so that the terminal device continues to maintain the communication connection with the base station. The embodiments of the present application mainly consider cell handover across base stations, and the “cell handover” described below can be understood as “cell handover across base stations”. For example, refer to FIG. 3, which is a schematic diagram of cell handover for terminal equipment. It can be seen from Figure 3 that the terminal equipment needs to be handed over from the source base station to the target base station. In addition, please refer to Figure 4 again, which is a flow chart of the cell handover process. Figure 4 does not show the operation of the core network side.

S41. The source base station sends a handover preparation information (handover preparation information) message to the target base station, and the target base station receives the handover preparation information message from the source base station. The handover preparation information message is used to instruct the terminal device to be handed over from the source base station to the target base station.

Among them, before the terminal device performs cell handover, that is, before performing S41, the source base station will issue configuration information to the terminal device, for example, called configuration information 1. The configuration information 1 may include one or more IEs, and the configuration information 1 is used for The terminal equipment communicates under the source base station.

During the cell handover process, the source base station will send configuration information 1 to the target base station. For example, the source base station may include the configuration information 1 in the handover preparation information message and send it to the target base station.

S42. The target base station performs admission control. That is, the target base station determines whether to allow the terminal device to switch to the target base station.

S43. If the target base station allows the terminal device to switch to the target base station, the target base station sends a handover control (handover command) message to the source base station, and the source base station receives the handover control message from the target base station.

The handover control message may indicate that the target base station allows the terminal device to be handed over to the target base station.

S44. The source base station sends an RRC reconfiguration (RRC reconfiguration) message to the terminal device, and the terminal device receives the RRC reconfiguration message from the source base station.

The RRC reconfiguration message may also be referred to as a handover command, which may instruct the terminal device to switch from the source base station to the target base station.

During the cell handover process, the target base station will also issue configuration information to the terminal device, for example called configuration information 2. The configuration information 2 may include one or more IEs, and the configuration information 2 is used for the terminal device to communicate under the target base station. The configuration information 2 may be determined according to the configuration information 1. For example, the target base station may include the configuration information 2 in the handover control message in S43 and send it to the source base station, and the source base station may then include the configuration information 2 in the RRC reconfiguration message in S44 and send it to the terminal device.

S45. The terminal device performs a handover operation to switch from the source base station to the target base station, or in other words, switch from the current serving cell to the new cell.

S46. The terminal device sends an RRC reconfiguration complete (RRC reconfiguration complete) message to the target base station, and the target base station receives the RRC reconfiguration complete message from the terminal device.

The completion of RRC reconfiguration can indicate that the terminal device has been switched.

Through the process shown in Figure 4, the terminal equipment completes the cell handover process. After the terminal device switches to the target base station, the configuration information 2 can be applied.

The communication version supported by each base station may be different, so the communication version of the source base station and the target base station may be different. For example, the communication version of the source base station may be higher than the communication version of the target base station. Since the base station of the higher version supports more functions than the base station of the lower version, the base station of the higher version can be configured with more IEs, but the base station of the lower version cannot recognize the IE corresponding to the new function because it does not have new functions. Since the target base station cannot recognize these IEs, it will not send these IEs to the terminal device. However, some IEs correspond to the demand code need M, such as the IE that includes overheating configuration information. If the terminal device received the IE last time, but did not receive the IE this time, it indicates that the terminal device needs to continue to apply the last received IE. The configuration corresponding to this IE. For this type of IE, if the terminal device determines that the source base station has sent the IE to the terminal device, but the target base station has not sent the IE to the terminal device, the terminal device will continue to use the configuration corresponding to the IE from the source base station. However, the target base station cannot recognize the IE, and naturally cannot support the configuration corresponding to the IE, which may cause the terminal device to fail to communicate normally under the target base station.

In view of this, the technical solutions of the embodiments of the present application are provided. For example, the first field is a field that needs to be inherited, that is, if the terminal device received the first field last time, but did not receive the first field this time, then the terminal device needs to continue to apply the configuration corresponding to the first field received last time , In other words, the demand code corresponding to the first field is need M. Then in this embodiment of the application, if the terminal device determines that the first configuration information from the first network device includes the first field, and the first configuration information from the second network device does not include the first field, the terminal device can release The configuration corresponding to the first field included in the first configuration information, that is, the terminal device no longer applies the previously received configuration corresponding to the first field. The second network device did not send the first field to the terminal device. It is probably because the second network device cannot recognize the first field. Therefore, the terminal device releases the configuration corresponding to the first field, which can make the terminal device and the second network device apply The fields are kept consistent, so that the terminal device can communicate normally under the second network device.

For example, when a user is holding a smart phone for a call service while walking, the smart phone may perform a cell handover due to the user's movement. However, due to the above problems, the smart phone may not be able to communicate normally when it is switched to the target base station, that is, the smart phone may have poor call signals, call interruptions, or call drops, which affects user experience. These problems can be solved by adopting the solutions provided by the embodiments of the present application. For example, after adopting the solution provided in the embodiment of this application, for example, the user is holding a smart phone while walking for a call service, the user’s movement may cause the smart phone to perform cell handover, but in the embodiment of this application, even if the smart phone is switched to the target Under the base station, since the actual configuration of the smart phone can be as consistent as possible with the configuration of the smart phone known by the target base station, the smart phone can also communicate normally under the target base station. That is to say, the technical solution provided by the embodiments of the present application can reduce the probability of poor call signal, call interruption, or call dropped after the smart phone performs cell handover, improve communication quality, and improve user experience. .

The technical solutions provided by the embodiments of this application can be applied to the fourth generation mobile communication technology (the 4th generation, 4G) system, such as the LTE system, or can be applied to the 5G system, such as the NR system, or can also be applied to the next generation Mobile communication systems or other similar communication systems are not specifically restricted. In addition, the technical solutions provided by the embodiments of this application can be applied to device-to-device (D2D) scenarios, such as NR-D2D scenarios, etc., or can be applied to vehicle to everything (V2X) scenarios, such as NR-V2X scenes, etc., for example, can be applied to the Internet of Vehicles, such as V2X, vehicle-to-vehicle (V2V), etc., or can be used in fields such as intelligent driving, assisted driving, or intelligent networked vehicles.

An application scenario of the embodiment of the present application can continue to refer to FIG. 3. The base station in Figure 3 may be an access network device. Among them, the access network equipment corresponds to different equipment in different systems. For example, in a 4G system, it can correspond to an eNB, and in a 5G system, it corresponds to an access network equipment in 5G, such as gNB. Of course, the technical solutions provided by the embodiments of the present application can also be applied to future mobile communication systems, so the access network equipment can also correspond to network equipment in future mobile communication systems. Figure 3 takes the access network equipment as a base station as an example. In fact, referring to the previous introduction, the access network equipment may also be equipment such as RSU.

The following describes the method provided by the embodiment of the present application with reference to the accompanying drawings. It should be noted that in the various embodiments of this application, all information interactions between the terminal device and the core network device can be forwarded from it through the access network device, just because the solution in the embodiment of this application does not involve the core network. Equipment, so it is not mentioned below. In addition, the configuration information described in the various embodiments of the present application, such as the first configuration information, the second configuration information, the third configuration information, or the fourth configuration information, can all include the parameters configured by the network device for the terminal device, so that the terminal The device can work under the network device. Exemplarily, the parameters configured by the network device for the terminal device may include one or more of radio bearer configuration parameters, physical layer parameters, MAC parameters, RLC parameters, or security parameters, or may also include other parameters.

The embodiment of the present application provides a first method for configuring a terminal device. Please refer to FIG. 5, which is a flowchart of this method. In the following introduction process, the application of this method to the network architecture shown in FIG. 3 is taken as an example.

For ease of introduction, in the following, the method executed by the network device and the terminal device is taken as an example. The first network device described below is the source network device of the terminal device, that is, the network device that the terminal device accesses before cell handover, and the second network device described below is the target network device of the terminal device, that is, The network equipment that the terminal equipment accesses after the cell handover. Then the terminal device described below may be the terminal device in the network architecture shown in FIG. 3, and the first network device described below may be the source base station in the network architecture shown in FIG. The second network device may be the target base station in the network architecture shown in FIG. 3.

S51. The first network device sends third configuration information to the terminal device, and correspondingly, the terminal device receives the third configuration information from the first network device.

For example, before the cell handover, the first network device as the source network device may send the third configuration information to the terminal device. For example, the first network device may send the third configuration information to the terminal device when the terminal device just enters the network (for example, when completing random access with the first network device), and after that, the terminal device is under the first network device When working, the first network device no longer sends other configuration information to the terminal device; or, the first network device can send configuration information to the terminal device when the terminal device just enters the network (for example, when completing random access with the first network device) After that, when the terminal device is working under the first network device, the first network device can also send new configuration information to the terminal device. For the first network device and the terminal device, it can be based on the new configuration information. The configuration information of and the previous configuration information obtains the currently applied configuration information. In this case, for example, the third configuration information is the most recent configuration information sent by the first network device to the terminal device. Alternatively, the first network device may also send the third configuration information to the terminal device during the cell handover process. For example, according to the cell handover process introduced above, during the cell handover process, the source network device sends a handover command to the terminal device (the handover command is, for example, the RRC reconfiguration message in S44 in the process shown in Figure 4) to instruct the terminal The device switches, then the first network device may include the third configuration information in the switching command and send it to the terminal device.

As mentioned in the previous article, the current configuration process is iterative configuration, or the configuration of inheritance system, that is, the configuration of the next is based on the previous configuration. Then, for example, the third configuration information is the configuration information that the first network device recently sent to the terminal device, or in other words, the first network device has already sent other configuration information to the terminal device before sending the third configuration information to the terminal device, For example, the fourth configuration information, then the third configuration information is a further configuration based on the fourth configuration information. Therefore, the terminal device can determine the configuration information applied by the terminal device according to the third configuration information and the fourth configuration information, The configuration information is referred to as the first configuration information. The terminal device can be configured using the first configuration information, so that the terminal device can normally perform data communication under the first network device.

The first configuration information may include one or more fields, such as an IE, or a domain, or other concepts. It can be understood that a field includes one or more bits. For the fields included in the third configuration information, each field may correspond to a demand code, and the demand codes corresponding to different fields may be the same or different. In addition, each field can include a parameter. For example, the first configuration information may include a first field, and the first field includes, for example, a parameter, or in other words, includes corresponding information. For the terminal device, if the first field is not received, it needs to inherit (or apply) the content of the first field received last time, or in other words, it needs to continue to apply the configuration corresponding to the content of the first field received last time. In other words, the first parameter needs to be applied continuously. For example, if the demand code corresponding to the first field is need M, then the first field is the field that needs to be inherited. For example, the first field may include overheating configuration information, or the first field may also include other information.

The overheating configuration information includes, for example, the first indication information, or includes the timing duration of the prohibition timer, or includes the first instruction information and the timing duration of the prohibition timer. Wherein, the first indication information may be used to indicate whether the auxiliary information related to overheating can be sent to the network device. The prohibition timer is a prohibition timer related to overheating, and the prohibition timer can be used to control the frequency of the terminal device sending auxiliary information related to the overheating to the network device. For example, if the overheating configuration information includes the first indication information and the timing duration of the prohibition timer, and the first indication information indicates that the auxiliary information related to overheating can be sent to the network device, the terminal device may send the auxiliary information related to overheating to the network device, When sending the auxiliary information related to overheating or after sending the auxiliary information related to overheating, the terminal device starts the prohibition timer. Similarly, the network device receives the auxiliary information related to overheating or after receiving the auxiliary information related to overheating. , Also turn on the prohibit timer. During the running time of the prohibition timer, the terminal device cannot send the auxiliary information related to overheating to the network device, and the terminal device can only send the auxiliary information related to the overheating to the network device when the prohibition timer expires or after the timeout. For example, the value range of the timer duration of the prohibition timer can be {s0,s0dot5,s1,s2,s5,s10,s20,s30,s60,s90,s120,s300,s600,spare3,spare2,spare1}, about For the related introduction of this range, please refer to the previous article.

S52. The terminal device sends the auxiliary information related to overheating to the first network device, and the first network device receives the auxiliary information related to overheating from the terminal device.

If the overheating configuration information includes the first indication information, and the first indication information is used to indicate that the auxiliary information related to overheating can be sent to the network device, if the terminal device has an overheating problem, the terminal device can send the overheating related information to the first network device. Supplementary information. Or, if the overheating configuration information includes the first indication information and the timing duration of the prohibition timer, then, if the terminal device has an overheating problem and the prohibition timer is not running, the terminal device can send overheating related information to the first network device. Supplementary information. For example, the terminal device may include the auxiliary information related to overheating in the UE auxiliary information message and send it to the first network device.

In the embodiment of the present application, the auxiliary information related to overheating may include one or more of the following: the maximum number of uplink auxiliary carriers or the maximum number of uplink auxiliary cells supported by the terminal device, the maximum number of downlink auxiliary carriers or the maximum number of downlink auxiliary carriers supported by the terminal device The number of secondary cells, the maximum uplink aggregate bandwidth that the terminal device can support in each supported frequency band, the maximum downlink aggregate bandwidth that the terminal device can support in each frequency band supported, and the terminal device in each supported frequency band The maximum number of uplink MIMO layers that can be supported by each serving cell, the maximum number of downlink MIMO layers that can be supported by each serving cell in each frequency band supported by the terminal device, or the type information of the terminal device. For example, the auxiliary information related to overheating may include the maximum number of uplink auxiliary carriers supported by the terminal device; or, the auxiliary information related to overheating may include the maximum number of auxiliary cells in the downlink supported by the terminal device; or, the auxiliary information related to overheating may include the terminal device's The maximum uplink aggregate bandwidth that each supported frequency band can support, and the maximum downlink aggregate bandwidth that the terminal device can support in each supported frequency band; or, the auxiliary information related to overheating may include the maximum aggregate bandwidth supported by the terminal device in each frequency band supported. The maximum downlink aggregate bandwidth that can be supported by each frequency band, the maximum number of uplink MIMO layers that can be supported by each serving cell of each frequency band supported by the terminal device, and the type information of the terminal device; or, auxiliary information related to overheating It can include the maximum number of uplink auxiliary carriers or the maximum number of uplink auxiliary cells supported by the terminal device, the maximum number of downlink auxiliary carriers or the maximum number of downlink auxiliary cells supported by the terminal device, and the maximum uplink aggregation that the terminal device can support in each supported frequency band Bandwidth, the maximum downlink aggregate bandwidth that the terminal device can support in each supported frequency band, the maximum number of uplink MIMO layers that each serving cell of each supported frequency band of the terminal device can support, and the maximum number of uplink MIMO layers supported by the terminal device in each frequency band supported. The maximum number of downlink MIMO layers that can be supported by each serving cell on each supported frequency band, and so on.

It should be noted that the configuration indicated by the auxiliary information related to overheating (which can be understood as the value of the parameter included in the auxiliary information related to overheating) is the desired configuration of the terminal device, not the actual capability of the terminal device. The supported configuration, for example, the configuration indicated by the auxiliary information related to overheating, may be lower than or equal to the configuration actually supported by the capabilities of the terminal device. It can be understood that if the terminal device applies the configuration indicated by the auxiliary information related to overheating, the overheating of the terminal device can be improved. For example, the auxiliary information related to overheating includes the maximum number of uplink MIMO layers that the terminal device can support in each serving cell on each supported frequency band. The number of MIMO layers is, for example, 2, which indicates that the terminal device expects the first network device Configure the maximum number of uplink MIMO layers supported by each serving cell of the terminal device in each supported frequency band to 2, but the terminal device can actually be able to support each serving cell in each supported frequency band. The maximum number of MIMO layers supported in the uplink may be 4, that is, the terminal device expects to reduce the number of MIMO layers to improve the overheating of the terminal device.

Among them, as described herein, each frequency band supported by the terminal device includes, for example, two frequency bands of high frequency (FR2) and low frequency (FR1), or more frequency bands may be divided according to a finer granularity.

S53. The first network device sends an RRC reconfiguration message to the terminal device, and the terminal device receives the RRC reconfiguration message from the first network device. The RRC reconfiguration message includes air interface configuration information. Because the cell handover process has not been involved at this time, the RRC reconfiguration message is not the RRC reconfiguration message in S44 in the process shown in FIG. 4.

If the first network device receives the auxiliary information related to overheating from the terminal device, the first network device can decide whether to reduce the air interface configuration of the terminal device, thereby alleviating the overheating problem of the terminal device. As for how to make a decision, it depends on the internal implementation of the first network device. If the first network device decides to reduce the air interface configuration of the terminal device, the first network device may determine the air interface configuration information according to the received auxiliary information related to overheating, and include the air interface configuration information in the RRC reconfiguration message and send it to the terminal device. After receiving the air interface configuration information, the terminal device can apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before the air interface configuration is reduced, the capability of the terminal device is the second capability, and after the air interface configuration is reduced, the capability of the terminal device is the first capability, and the first capability is lower than the second capability. The second capability is, for example, the maximum capability actually supported by the terminal device, or may also be lower than the maximum capability actually supported by the terminal device. After the terminal device uses the reduced air interface configuration for communication, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the problem of overheating. Alternatively, if the first network device decides not to reduce the air interface configuration of the terminal device, the first network device may not need to send the air interface configuration information to the terminal device, for example, it may not be necessary to perform S53.

The parameters included in the air interface configuration information configured by the first network device and the parameters included in the auxiliary information related to overheating may be consistent. For example, the auxiliary information related to overheating includes the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device in each supported frequency band, and the air interface configuration information also includes the terminal device's maximum number of MIMO layers in each supported frequency band. The maximum number of uplink MIMO layers that each serving cell can support. In this case, the value of the parameter included in the air interface configuration information and the value of the parameter included in the auxiliary information related to overheating may be the same or different. For example, the overheating-related auxiliary information includes the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device in each supported frequency band is 2, and the terminal device has a maximum number of MIMO layers in each supported frequency band. The maximum number of uplink MIMO layers that a serving cell can actually support is 4. Then, the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device in each supported frequency band included in the air interface configuration information may be two or three. That is, the first network device can determine the air interface configuration information completely according to the auxiliary information related to overheating, or the first network device can also consider other factors when determining the air interface configuration information, which makes the determined air interface configuration information not completely equivalent to overheating Recommendations for related auxiliary information.

Alternatively, the parameters included in the air interface configuration information configured by the first network device and the parameters included in the auxiliary information related to overheating may also be different. For example, the auxiliary information related to overheating includes the maximum number of uplink MIMO layers that the terminal device can support in each serving cell on each frequency band supported, and the air interface configuration information may not include this parameter, but includes the terminal device support Maximum number of uplink auxiliary carriers. It can be seen that the first network device has certain flexibility in determining the air interface configuration information.

Among them, S52 and S53 are only optional steps, which are not necessary to be performed, and are represented by dashed lines in FIG. 5.

S54. During the cell handover process, the first network device sends the third configuration information to the second network device, and the second network device receives the third configuration information from the first network device. For example, the first network device may include the third configuration information in the handover preparation information message described in S41 in the process shown in FIG. 4 and send it to the second network device, or may also include the third configuration information in other The message is sent to the second network device.

After receiving the third configuration information, the second network device may determine the second configuration information according to the third configuration information, and the second configuration information may be used for communication of the terminal device under the second network device. For example, for some fields already included in the third configuration information, the second network device may reconfigure the contents of these fields (for example, reconfigure the values of the parameters included in these fields), or may not need to reconfigure, but continue Use the contents of these fields included in the third configuration information. For example, for a field with a corresponding demand code of need M, if the second network device needs to reconfigure the content of the field, the second network device may include the field in the second configuration information, so that the terminal device receives the second configuration After the information, the configuration corresponding to the field included in the second configuration information will be applied; and if the second network device does not need to configure the content of the field, the second network device does not need to include the field in the second configuration information, After the terminal device receives the second configuration information and finds that the second configuration information does not include this field, but the first configuration information includes this field, the terminal device will continue to apply the configuration corresponding to the field included in the first configuration information. For the fields corresponding to other demand codes, the second network device can be configured according to the characteristics of the corresponding demand codes. Similarly, for these fields, the second network device can choose to reconfigure or continue to use the third configuration information. The corresponding configuration of this field.

For example, the communication version of the first network device is version 1, and the communication version of the second network device is version 2, for example, version 1 is v1540, version 2 is v1520, and so on. If version 1 is higher than version 2, then for one or more fields included in the third configuration information, if some fields correspond to version 1, or correspond to other versions between version 1 and version 2, and do not correspond to version 2. It does not correspond to any other versions lower than version 2, and the second network device cannot recognize these fields, or in other words, cannot interpret these fields. In other words, a network device cannot identify a field higher than the communication version supported by the network device. For fields that cannot be recognized by the second network device, the second network device does not include such fields in the second configuration information.

S55. The second network device sends the second configuration information to the terminal device, and correspondingly, the terminal device receives the second configuration information from the second network device.

For example, the second network device may first send the second configuration information to the first network device, and then the first network device sends the second configuration information to the terminal device. For example, the second network device may include the second configuration information in the handover control message described in S43 in the process shown in FIG. 4 and send it to the first network device, and the first network device may include the second configuration information as The RRC reconfiguration message described in S44 in the process shown in FIG. 4 is sent to the terminal device. It was introduced in S51 that the first network device can send the third configuration information to the terminal device before the cell handover, or can send the third configuration information to the terminal device through the RRC reconfiguration message during the cell handover. Then, if the first network device sends the third configuration information to the terminal device through the RRC reconfiguration message, and sends the second configuration information to the terminal device through the RRC reconfiguration message, the third configuration information and the second configuration information are passed through A message was sent.

S56. The terminal device determines that the first configuration information includes the first field, and the second configuration information does not include the first field. Or, for some fields, if the content of the field is empty, the effect is the same as if the field is not included. That is, if the field is included in the configuration information, but the content of the field is empty, it can also be regarded as The configuration information does not include this field. For such a field, S56 may also be that the terminal device determines that the first configuration information includes the first field and the second configuration information also includes the first field, but the content of the first field included in the second configuration information is empty. The embodiment of the present application mainly takes as an example the terminal device determining that the first configuration information includes the first field and the second configuration information does not include the first field.

Among them, the first field is a field that needs to be inherited. This can be understood as when the terminal device does not receive the first field, the terminal device needs to inherit the content of the first field received last time, or in other words, the terminal device needs to continue to apply The configuration corresponding to the first field received this time. Or it is understood that the first field is a field in which the terminal device needs to keep the content of the first field received last time when the configuration information newly received by the terminal device (for example, the second configuration information) does not include the first field. For example, the demand code corresponding to the first field is need M.

Because the second configuration information is a further configuration based on the first configuration information, after receiving the second configuration information, the terminal device can compare the second configuration information with the first configuration information to determine the configuration information that should actually be applied . For example, if the second network device cannot identify some of the fields included in the first network device, the second configuration information will not include this portion of the fields. And these fields may have fields that need to be inherited (for example, the first field). Since the second configuration information does not include such fields, the terminal device will continue to apply the configuration corresponding to such fields included in the first configuration information. The configuration corresponding to this type of field is not supported by the second network device. If the terminal device continues to use the configuration corresponding to this type of field included in the first configuration information, it may cause the terminal device to communicate under the second network device. The problem, for example, the terminal device may not be able to perform normal data communication with the second network device. Therefore, in this embodiment of the application, the terminal device may determine that the first configuration information includes fields that are not included in the second configuration information. For example, the terminal device may determine one or more such fields, and the one or more fields may include the first configuration information. One field. Among them, for the same field, it will have the same identifier, and the terminal device can determine whether the configuration information includes the corresponding field according to the identifier of the field.

S57. The terminal device releases the configuration corresponding to the first field included in the first configuration information, or in other words, releases the content of the first field included in the first configuration information.

For each field in one or more fields that are included in the first configuration information but not included in the second configuration information, the terminal device can determine the demand code corresponding to the field, and if the demand code corresponding to the field indicates that the field does not need to be inherited For example, if the demand code of this field is need N, the terminal device may not take corresponding actions; or, if the demand code of this field is need R, the terminal device may release the configuration corresponding to this field. Or, if the demand code corresponding to the field indicates that the field is a field that needs to be inherited, for example, the first field is a field that needs to be inherited, for example, the demand code corresponding to the first field is need M, then the terminal device can release such a field The configuration corresponding to the field included in the first configuration information, that is, the terminal device will not continue to apply the configuration corresponding to the field included in the first configuration information. In this way, the terminal device does not need to determine the communication version corresponding to the field, as long as a field is included in the first configuration information and not included in the second configuration information, and the field is a field that needs to be inherited, the terminal device can The configuration corresponding to the field included in the first configuration information is released, so that the terminal device no longer applies the configuration corresponding to the field included in the first configuration information. It can be understood that the terminal device releases the configuration corresponding to the field.

For example, the first field includes overheating configuration information, and the demand code corresponding to the first field is needM. The first field is included in the first configuration information, but is not included in the second configuration information. Then the terminal device can release the content of the first field included in the first configuration information, so that the terminal device no longer applies the overheating configuration information included in the first field included in the first configuration information.

The fields not included in the second configuration information are likely to be fields that the second network device cannot recognize. If the terminal device inherits the configuration corresponding to the field included in the first configuration information, it is likely that the terminal device cannot communicate normally under the second network device. Therefore, in the embodiment of the present application, the terminal device does not inherit the configuration corresponding to the field included in the first configuration information, so that the actual configuration of the terminal device corresponds to the configuration of the terminal device understood by the second network device, ensuring that the terminal device Data communication can be carried out normally under the second network device.

Alternatively, in the embodiment of the present application, the terminal device may also determine the communication version corresponding to the field (for example, the field may include a version number, so that the terminal device may determine the communication version corresponding to a field), and then perform corresponding processing. For example, for each field in one or more fields that are included in the first configuration information but not included in the second configuration information, the terminal device may determine the demand code corresponding to the field, and if the demand code corresponding to the field indicates that the field is not Fields that need to be inherited, for example, if the demand code of this field is need N, the terminal device may not take corresponding actions; or, if the demand code of this field is need R, the terminal device may release the configuration corresponding to this field. Or, if the demand code corresponding to the field indicates that the field is a field that needs to be inherited, for example, the first field is the field that needs to be inherited, for example, the demand code corresponding to the first field is need M, and the communication version corresponding to the first field is first Version, for the first field, the terminal device can further determine whether the second network device can support the first version. For example, the method for the terminal device to determine whether the second network device can support the first version may include: determining whether the second configuration information includes other fields corresponding to the first version (for example, the terminal device may determine that the second information includes other than the first version). The communication version corresponding to one or more fields other than one field, to determine whether there is a field corresponding to the first version in these fields, and if there is, it is determined that the second configuration information includes other fields corresponding to the first version If not, determine whether the second configuration information does not include other fields corresponding to the first version), or determine whether the second configuration information includes other fields corresponding to any version higher than the first version (the determination method is similar to determining Whether the second configuration information includes other fields corresponding to the first version), or determine whether the second configuration information includes other fields corresponding to the first version, and determine whether the second configuration information includes a version higher than the first version Other fields corresponding to any version.

If the second configuration information includes other fields corresponding to the first version, or includes other fields corresponding to any version higher than the first version, or includes other fields corresponding to the first version and includes any other fields higher than the first version Version corresponding to other fields, then the terminal device can determine that the second network device can support the first version corresponding to the first field. The reason why the second configuration information does not include the first field may be that the second network device thinks that the terminal device needs Continue to apply the configuration corresponding to the first field included in the first configuration information. Therefore, in this case, the terminal device does not need to release the content of the first field included in the first configuration information, but can continue to apply the configuration corresponding to the first field included in the first configuration information. By determining the version, the terminal device can try not to release the content included in the fields that the second network device can support, so that the configuration of the terminal device and the second network device are consistent, and ensure that the terminal device can perform normally under the second network device. data communication.

Or, if the second configuration information neither includes other fields corresponding to the first version, nor any other fields corresponding to any version higher than the first version, the terminal device cannot determine whether the second network device supports the first field Corresponding to the first version, but if the second network device does not actually support the first version, if the terminal device continues to apply the configuration corresponding to the first field included in the first configuration information, it may cause the terminal device to be on the second network device There is a problem with the communication under the network, for example, the terminal device may not be able to perform normal data communication with the second network device. Therefore, in this case, the terminal device may release the content of the first field included in the first configuration information of the first field, and no longer continue to apply the configuration corresponding to the first field included in the first configuration information. In this way, the configuration of the terminal device and the second network device are kept consistent, and it is ensured that the terminal device can perform normal data communication under the second network device.

For example, if the first configuration information of the terminal device under the first network device includes overheating configuration information (such as other configuration (OtherConfig)-v1540 or overheating assistant configuration (overheatingAssistanceConfig), etc.), for example, the overheating configuration information is included in the first field In, the first field is, for example, an IE. If the second configuration information received by the terminal device does not include the first field, the terminal device may determine whether the second configuration information includes a field corresponding to the v1540 version or corresponding to any other version higher than the v1540 version. If the second configuration information includes a field corresponding to the v1540 version, or includes a field corresponding to any other version higher than v1540, it means that the second network device can support the v1540 version, or can support other versions higher than v1540 Version, the second network device can also support the first field. At this time, the terminal device does not have to release the content of the first field included in the first configuration information, that is, the overheating configuration information is not released, but can continue to apply the first field. The overheating configuration information included in the configuration information. Or, if the second configuration information neither includes a field corresponding to the v1540 version nor any other version higher than v1540, the terminal device cannot determine the communication version of the second network device, nor can it determine the first 2. Whether the network device can support the communication version corresponding to the first field. In this case, for the sake of safety, the terminal device may release the overheating configuration information included in the first configuration information, and no longer apply the overheating configuration information.

S58. The terminal device adjusts the capability of the terminal device from the first capability to the second capability. Among them, the first ability is lower than the second ability.

If S53 is executed and the terminal device adjusts the capability of the terminal device, S58 may be executed, or if the terminal device does not adjust the capability of the terminal device, S58 does not need to be executed. Therefore, S58 is an optional step, which is represented by a dashed line in FIG. 5. In S53, after receiving the air interface configuration information, the terminal device can apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before the air interface configuration is reduced, the capability of the terminal device is the second capability, and after the air interface configuration is reduced, the capability of the terminal device is the first capability, and the first capability is lower than the second capability. For example, the air interface configuration information includes the number of antennas of the terminal device. Before the air interface configuration is reduced, the number of antennas of the terminal device is 4, and the second capability is the 4-antenna capability. After the air interface configuration is reduced, the number of antennas of the terminal device If it becomes 2, the first capability is the 2-antenna capability. It can be seen that the first capability is lower than the second capability. The first capability may be considered as configured by the first network device to adapt to the content of the first field, or in other words, configured by the first network device to adapt the auxiliary information related to overheating received according to the first field. The second capability may be the maximum capability supported by the terminal device, for example, the maximum capability that the terminal device reports to the network through the UE capability information message when it enters the network, or the second capability may also be lower than the maximum capability supported by the terminal device and higher than the maximum capability supported by the terminal device. Any ability of an ability. After the terminal device uses the reduced air interface configuration for communication, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the problem of overheating.

If the terminal device needs to switch to the second network device, the second network device may not support the communication version corresponding to the first field, that is, the target network device cannot recognize the first field, so the second network device naturally cannot learn about the terminal device. The ability is adjusted according to the first field. Therefore, the terminal device can adjust the capability of the terminal device back to the second capability, so that the second network device can schedule the terminal device according to the second capability, reducing the ability of the terminal device and the actual application of the terminal device as understood by the second network device. The probability of scheduling errors caused by inconsistent capabilities. For example, the maximum number of uplink MIMO layers that a terminal device corresponding to the first capability can support in each serving cell in each supported frequency band is 2, while the terminal device corresponding to the second capability is in each supported frequency band. The maximum number of uplink MIMO layers that can be supported by each serving cell is 4, and the terminal device can adjust the maximum number of uplink MIMO layers that can be supported by each serving cell on each frequency band supported by the terminal device from 2 to 4.

In addition, in the embodiment of the present application, the configuration mode applied by the second network device is the configuration mode of inheritance system, or iterative configuration mode, that is, the configuration mode of the next time needs to be performed based on the previous configuration, for example, based on The third configuration information of the first network device determines the second configuration information, that is, the second configuration information is not configured in a full configuration manner. In practical applications, the second network device may also adopt a full configuration method, which is a method in which all fields to be configured to the terminal device are reconfigured. For example, if the second network device adopts the full configuration method, after the second network device receives the third configuration information from the third network device, if it is determined that the third configuration information includes a field that the second network device cannot recognize, then The second network device will clean up (for example, discard) all the parameters (or all fields) configured by the first network device for the terminal device, and reconfigure all the fields that need to be configured for the terminal device. In this case, the first The second configuration information is brand new configuration information configured by the second network device for the terminal device, and has nothing to do with the third configuration information. This method can also ensure that the terminal device and the second network device have the same understanding of the configuration information, so that the terminal device can communicate normally under the second network device. However, in this way, since it needs to be completely reconfigured, the amount of information included in the second configuration information may be relatively large, and the transmission overhead caused by this may also be relatively large. The embodiment of the present application does not limit the configuration mode adopted by the second network device. However, if the second network device adopts the full configuration mode, for the terminal device, there is no need to perform the behavior of releasing the fields that need to be inherited.

Therefore, as an optional implementation manner, the second network device may send configuration instruction information to the first network device, and the first network device may receive configuration instruction information from the second network device. The configuration instruction information may indicate that the second network device uses the full configuration mode to configure the terminal device, or indicates that the second network device does not use the full configuration mode to configure the terminal device. For example, the configuration instruction information may be sent to the first network device before the cell handover. For example, before the first network device sends a handover preparation information message (S41 in the process shown in FIG. 4) to the network device, the second network The device may send the configuration instruction information to the first network device, or the second network device may send the configuration instruction information to the first network device before sending the second configuration information to the terminal device, or the second network device may also send the configuration instruction information to the first network device. The configuration instruction information is sent together with the second configuration information. After receiving the configuration instruction information, the first network device may send the configuration instruction information to the terminal device, so that the terminal device can receive the configuration instruction information. For example, the first network device may include the configuration indication information in the RRC reconfiguration message (S44 in the process shown in FIG. 4) and send it to the terminal device. If the configuration instruction information indicates that the second network device does not use the full configuration mode to configure the terminal device, you can continue to implement the technical solution provided in the embodiment of this application; and if the configuration instruction information indicates that the second network device uses the full configuration mode to configure the terminal device, then It is not necessary to implement the technical solutions provided in the embodiments of the present application. For example, if the configuration instruction information instructs the second network device to configure the terminal device in the full configuration mode, after receiving the second configuration information, the terminal device can apply all or part of the configuration included in the second configuration information. The configuration information of a network device (for example, the first configuration information) can be discarded by the terminal device.

In addition, the embodiment of the present application can continue to perform the cell handover process. For example, if the first network device sends the second configuration information to the terminal device through a handover command, the terminal device can continue to perform the process shown in FIG. 4 S45 and other steps.

In this embodiment of the application, if the terminal device determines that the first configuration information from the first network device includes the first field, and the first configuration information from the target network device does not include the first field, the terminal device can release the first field. The configuration corresponding to the first field included in the configuration information, that is, the terminal device no longer applies the previously received configuration corresponding to the first field. The second network device did not send the first field to the terminal device. It is probably because the second network device cannot recognize the first field. Therefore, the terminal device releases the configuration corresponding to the first field, which can make the terminal device and the second network device apply The fields are kept consistent, so that the terminal device can communicate normally under the second network device.

In order to solve the same technical problem, an embodiment of the present application provides a second method for configuring a terminal device. Please refer to FIG. 6, which is a flowchart of this method. In the following introduction process, the application of this method to the network architecture shown in FIG. 3 is taken as an example.

S61. The second network device sends version indication information to the first network device, and the first network device receives the version indication information from the second network device. The version indication information may indicate the communication version of the second network device, for example, the communication version of the second network device is the second version.

For example, S61 can be performed before the cell handover is performed. For example, before the first network device sends the handover preparation information message (S41 in the process shown in FIG. 4) to the second network device, the second network device may send version indication information to the first network device.

S62. The first network device determines that the second version is lower than the first version. The first version is the communication version of the first network device. For example, the first version is v1540, the second version is v1520, or the first version is v1540, the second version is v1530, and so on.

S63. The first network device sends the first information to the terminal device, and the terminal device receives the first information from the first network device. The first information may be used to indicate the release of the configuration corresponding to the first field. The first field is a field that needs to be inherited. For example, the first field is a field that the terminal device needs to keep the content of the first field received last time when the configuration information newly received by the terminal device does not include the first field, for example, the first field The corresponding demand code is need M. For more explanation of the first field, reference may be made to the related description of the embodiment shown in FIG. 5.

S63 may also occur before the cell handover. For example, before the first network device sends the handover preparation information message to the second network device (S41 in the process shown in FIG. 4), the first network device sends the first network device to the terminal device. information.

A network device cannot identify fields corresponding to other communication versions that are higher than the communication version of the network device. Before cell handover, the terminal device works under the first network device, and the first network device sends corresponding configuration information to the terminal device. For example, the first network device sends configuration information 1 to the terminal device, and the terminal device according to the configuration information 1 The configuration information 2 can be obtained, and configuration can be performed according to the configuration information 2, so that it can communicate with the first network device normally. Regarding the process for the terminal device to obtain the configuration information 2 according to the configuration information 1, refer to the related introduction of the embodiment shown in FIG. 5 (wherein, the "first configuration information" in the related introduction of the embodiment shown in FIG. One name is replaced with "configuration information 2" here, and the name "third configuration information" in the related introduction of the embodiment shown in FIG. 5 is replaced with "configuration information 1" here).

During the cell handover process, the first network device will also send configuration information 1 to the second network device, and the second network device can determine the configuration of the second network device to the terminal device according to the configuration information 1, for example, called configuration information 3. . However, the communication version of the first network device is higher than the communication version of the second network device. Therefore, the configuration information 1 includes the fields corresponding to the first version, and the fields corresponding to the other versions between the first version and the second version. Field, the second network device cannot recognize it. For unrecognized fields, the configuration information 3 determined by the second network device will not include this part of the fields. And these fields may have fields that need to be inherited (such as the first field). Since the configuration information 3 from the second network device does not include such fields, the terminal device will continue to apply the configuration information from the first network device (such as the configuration Information 2) The configuration corresponding to such fields included. The configuration corresponding to this type of field is not supported by the second network device. If the terminal device continues the configuration corresponding to this type of field included in the configuration information 2, it may cause communication problems for the terminal device under the second network device. For example, the terminal device may not be able to perform normal data communication with the second network device.

For this reason, in this embodiment of the application, if the first network device determines that the second version is lower than the first version, then the first network device can instruct the terminal device to release all or part of it by sending the first information to the terminal device. The configuration corresponding to the field that needs to be inherited (in other words, release all or part of the content included in the field that needs to be inherited). All or part of the fields that need to be inherited may be the fields included in the configuration information 2. That is, the first network device may instruct the terminal device to release the configuration corresponding to all or part of the fields that need to be inherited included in the configuration information 2. For example, the first field is one of all or part of the fields that need to be inherited. For example, the first field includes overheating configuration information. The overheating configuration information may include second indication information, or include the timing duration of the prohibit timer, or include the second Indication information and the timing duration of the prohibition timer. The second indication information can be used to indicate whether the auxiliary information related to overheating can be sent to the network device. During the running time of the prohibit timer, the terminal device cannot send the auxiliary information related to overheating to the network device. For the introduction of overheating configuration information and auxiliary information related to overheating, refer to the embodiment shown in FIG. 5. Among them, the "first indication information" in the embodiment shown in FIG. 5 is equivalent to the "second indication information" here.

As an optional implementation manner, all or part of the fields that need to be inherited may include fields corresponding to the first version, including fields corresponding to other versions between the first version and the second version, or It includes fields corresponding to the second version, and may also include fields corresponding to other versions lower than the second version. For example, if the second version is v1520 and the first version is v1540, the first indication information can instruct the terminal device to release the fields that need to be inherited corresponding to v1540, release the fields that need to be inherited corresponding to v1530, and release the need to inherit fields corresponding to v1520. And release the fields corresponding to v1510 that need to be inherited. That is, in this way, the first network device does not determine the version corresponding to the field, nor does it need to determine the specific version of the second network device. As long as the second version is lower than the first version, then as long as the configuration information 2 includes Regardless of whether the second network device supports the fields that need to be inherited, the first network device can also instruct the terminal device to release it. In this way, the terminal device will no longer inherit these fields, so that the terminal device and the second network device have the same understanding of the fields, so that the terminal device can communicate normally under the second network device.

As another optional implementation manner, all or part of the fields that need to be inherited may include fields corresponding to the first version, including fields corresponding to other versions between the first version and the second version, but It does not include the fields corresponding to the second version, nor does it include the fields corresponding to other versions lower than the second version. Because the communication version of the second network device is the second version, no matter the fields corresponding to the second version or the fields corresponding to other versions lower than the second version, the second network device can support. If the first network device includes these fields in the configuration information and sends it to the second network device, the second network device can be identified and can also make further configurations based on these fields. Therefore, in this way, the first network device needs to determine the specific version of the second network device, and also the version corresponding to the field. The first network device just instructs the terminal device to release the field corresponding to the first version, and release the field corresponding to the first version. Fields of other versions between the first version and the second version, or the first network device instructs to release the fields higher than the second version, but does not need to release the fields corresponding to the second version, and does not need to release the fields corresponding to the lower version Fields corresponding to other versions of the second version. This can also make the second network device and the terminal device have consistent understanding of the configuration information, and the terminal device needs to release fewer fields, which can reduce the workload of the terminal device. Moreover, for these unreleased fields that can be recognized by the second network device, the second network device can also perform further configuration, which helps reduce the workload of the second network device.

Among them, the first information can be implemented in different ways.

As a first optional implementation manner of the first information, the first information may be configuration information. For example, the first information may be obtained according to the configuration information 2. All or part of the fields that need to be inherited in the configuration information 2 The content of each field of is set as the first content, and the configuration information obtained from this can be the first information. The first content may indicate the release of the corresponding field. For example, if the configuration information 2 includes the first field, then the first information also includes the first field, and the content of the first field is the first content, and the first content is used to indicate the release of the configuration corresponding to the first field, or to indicate To release the content of the first field, it can also be understood that the content of the first field is the first content, that is, the content of the first field is set to "release". Then after the terminal device receives the first information, according to the first content included in the first field, the content of the first field included in the configuration information 2 stored on the terminal device side will be released, so that the content included in the configuration information 2 is no longer applied. The configuration corresponding to the first field of.

In this implementation manner, it is equivalent to the first network device resending configuration information to the terminal device, and the configuration information is used to instruct to release all or part of the fields included in the configuration information 2 that need to be inherited. This indication method is relatively clear for the terminal device, and the terminal device can determine which fields need to be released according to the fields included in the first information.

As a second optional implementation manner of the first information, the first information may be indication information, for example referred to as first indication information, and the first indication information may occupy one or more bits. The first indication information may indicate to release the configuration corresponding to one or more fields, and the first field is, for example, one of the one or more fields. For example, the first indication information occupies one bit. If the value of this bit is "0", it means that the configuration corresponding to one or more fields is released. If the value of this field is "1", it means that the configuration is not released. The configuration corresponding to one or more fields. Alternatively, the first indication information may occupy one or more bits. If the first network device sends the first indication information to the terminal device, it means that the configuration corresponding to one or more fields is released. If the first network device does not send the first indication information to the terminal device Sending the first indication information means that the configuration corresponding to one or more fields is not released. These one or more fields are all fields that need to be inherited. These one or more fields are all or part of the fields that need to be inherited included in the configuration information 2. That is to say, the first indication information is used to indicate the release of the configuration information 2 All or part of the included fields need to be inherited. After receiving the first indication information, the terminal device can release all or part of the content of the fields that need to be inherited included in the configuration information 2 stored on the terminal device side, so that the configuration corresponding to these fields included in the configuration information 2 is no longer applied. For example, the field released by the terminal device includes the first field.

In this implementation manner, the first network device does not need to resend the configuration information to the terminal device, but only needs to send the first indication information to the terminal device to instruct the release of the corresponding field. Compared with the configuration information, the information amount of the first indication information is small, which helps to save transmission overhead.

S64. The first network device sends the first configuration information to the second network device, and correspondingly, the second network device receives the first configuration information from the first network device. For example, the first network device may include the first configuration information in a handover preparation information message (for example, S41 in the process shown in FIG. 4) and send it to the second network device.

For example, the first network device may obtain the first configuration information according to the configuration information 2. For example, the first network device deletes all or part of the fields that need to be inherited from the configuration information 2, and the configuration information obtained therefrom may be the first configuration information. The fields deleted by the first network device from the configuration information 2 are the fields that the first network device instructs the terminal device to release. According to the introduction of S63, the fields deleted by the first network device may include fields corresponding to all versions, and all versions here include the first version, the second version, other versions between the first version and the second version, and Other versions lower than the second version. For example, if the first network device deletes the first field from the configuration information 2, the first configuration information does not include the first field. In this case, the first field may correspond to any one of all versions. Or, the fields deleted by the first network device only include the fields corresponding to the first version and the fields corresponding to other versions between the first version and the second version, but do not include the fields corresponding to the second version, nor Include fields corresponding to other versions lower than the first version. For example, if the first network device deletes the first field from the configuration information 2, the first configuration information does not include the first field. In this case, the first field may correspond to the second version, or correspond to the second version and the second version. Other versions between one version.

After obtaining the first configuration information, the second network device can configure the terminal device according to the first configuration information. Since the first configuration information does not include fields that need to be inherited that the second network device cannot recognize, the second network device can configure the terminal device normally. For example, the second network device may obtain the second configuration information. For example, the second configuration information may be obtained according to the first configuration information. For fields that need to be inherited that can be supported by the second network device, if the second network device needs to be configured, the field may be included in the second configuration information.

S65. The second network device sends the second configuration information to the terminal device, and correspondingly, the terminal device receives the second configuration information from the second network device.

After the second network device obtains the second configuration information, it can be sent to the terminal device, so that the terminal device can configure according to the second configuration information so as to be able to communicate normally under the second network device after switching to the second network device. For example, the second network device may first send the second configuration information to the first network device, and then the first network device sends the second configuration information to the terminal device. For example, the second network device may include the second configuration information in the handover control message described in S43 in the process shown in FIG. 4 and send it to the first network device, and the first network device may include the second configuration information as The RRC reconfiguration message described in S44 in the process shown in FIG. 4 is sent to the terminal device.

S66. The first network device sends a switching command to the terminal device, and correspondingly, the terminal device receives the switching command from the first network device. The handover command is, for example, the RRC reconfiguration message described in S44 in the process shown in FIG. 4, which can be used to instruct the terminal device to switch to the second network device. After performing S66, the steps such as S45 in the flow shown in FIG. 4 can be continued, that is, the cell handover process can be continued.

Wherein, if the first network device can include the second configuration information in the RRC reconfiguration message described in S44 in the process shown in FIG. 4 and send it to the terminal device, then S66 can actually be regarded as being included in S65.

In addition, in the embodiment of the present application, the configuration mode applied by the second network device is the configuration mode of inheritance system, or iterative configuration mode, that is, the configuration mode of the next time needs to be performed based on the previous configuration, for example, based on The first configuration information of the first network device determines the second configuration information, that is, the second configuration information is not configured in a full configuration manner. In practical applications, the second network device may also adopt a full configuration mode, which is a mode in which all fields to be configured to the terminal device are reconfigured. Regarding the full configuration mode, reference may be made to the related introduction of the embodiment shown in FIG. 5. The embodiment of this application does not limit the configuration method adopted by the second network device, but if the second network device adopts the full configuration method, for the first network device, there is no need to instruct the terminal device to release the fields that need to be inherited .
