Description

Method and equipment for configuring terminal equipment

The present application claims priority of chinese patent application entitled "a method for assisting overheating information configuration, UE and network device" filed by the chinese intellectual property office on 22/6/2020, application No. 202010570970.0, which is incorporated herein by reference in its entirety.

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and a device for configuring a terminal device.

Background

A handover from a base station to a base station is a change of the communication connection of the terminal device from the coverage area of one base station (source base station) to the coverage area of another base station (target base station) to another communication connection, so that the terminal device continues to maintain the communication connection with the base station. Before the terminal device performs cell handover, the source base station may issue configuration information to the terminal device, for example, the configuration information is referred to as configuration information 1, where the configuration information 1 may include one or more Information Elements (IEs), and the configuration information 1 is used for the terminal device to communicate under the source base station. During the cell switching process, the source base station will send configuration information 1 to the target base station. In the cell handover process, the target base station may also issue configuration information (forwarded by the source base station) to the terminal device (for example, referred to as configuration information 2), where the configuration information 2 may include one or more IEs, the configuration information 2 is used for the terminal device to communicate under the target base station, and the configuration information 2 may be determined according to the configuration information 1. The configuration information 2 may be applied after the terminal device is handed over to the target base station.

The communication versions supported by the various base stations may differ, and thus the communication versions of the source base station and the target base station may differ. For example, the communication version of the source base station may be higher than the communication version of the target base station. Since the high-version base station supports more functions than the low-version base station, the high-version base station can configure more IEs, but the low-version base station does not have new functions, and therefore cannot identify IEs corresponding to the new functions. The target base station cannot identify these IEs, and therefore these IEs are not sent to the terminal device. However, some IEs have the characteristic that if the terminal device has received the IE last time but has not received the IE this time, it indicates that the terminal device needs to continue to apply the configuration corresponding to the IE received last time. Thus, for such an IE, if the terminal device determines that the IE was sent by the source base station to the terminal device, but the IE was not sent by the target base station 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 identify the IE, and naturally cannot support the configuration corresponding to the IE, which may cause that the terminal device cannot normally communicate under the target base station.

Disclosure of Invention

The embodiment of the application provides a method and equipment for configuring terminal equipment, which are used for enabling IE applied by the terminal equipment to be consistent with IE applied by network equipment and ensuring normal communication of the terminal equipment under the network equipment.

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

The method may be performed by a first communication device, which may be a communication apparatus or a communication device, e.g. a chip, capable of supporting the communication apparatus to implement the functionality required for the method. Illustratively, the first communication device is a terminal device, or a chip provided in the terminal device for implementing a function of the terminal device, or another component for implementing a function of the terminal device. In the following description, the first communication device is taken as an example of a terminal device.

For example, the first field is a field that needs to be inherited, that is, if the terminal device has received the first field last time but has not received the first field this time, the terminal device needs to continue to apply the configuration corresponding to the first field received last time. Then, in this embodiment of the application, if it is determined 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 may release the configuration corresponding to the first field included in the first configuration information, that is, the terminal device does not apply the configuration corresponding to the first field received before. The second network device does not send the first field to the terminal device, possibly because the second network device cannot recognize the first field, the terminal device releases the configuration corresponding to the first field, so that the fields applied by the terminal device and the second network device are kept consistent, and the terminal device can normally communicate 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 may configure the terminal device to send overheating related information to the network device, or configure the terminal device not to send overheating 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, wherein the first indication information is used for indicating whether auxiliary information related to overheating can be sent to the network equipment or not; and/or the presence of a gas in the gas,

disabling a timed duration of a timer, wherein the terminal device is unable to send the overheating-related assistance information to the network device during the disabled timer's run time.

For example, if the overheating configuration information includes first indication information indicating that the overheating-related assistance information cannot be transmitted to the network device, the terminal device does not transmit the overheating-related assistance information 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 overheating-related auxiliary information can be sent to the network device, the terminal device may send the overheating-related auxiliary information to the network device, and the terminal device may start the prohibition timer when sending the overheating-related auxiliary information or after sending the overheating-related auxiliary information, and similarly, the network device may also start the prohibition timer when receiving the overheating-related auxiliary information or after receiving the overheating-related auxiliary information. During the running time of the prohibit 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 overheating to the network device when or after the prohibit timer expires. For another example, if the overheating configuration information includes the first indication information indicating that the overheating-related auxiliary information can be transmitted to the network device and the overheating configuration information does not include the timed duration of the prohibit timer, the terminal device may transmit the overheating-related auxiliary information to the network device when needed.

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

the maximum uplink auxiliary carrier number or the maximum uplink auxiliary cell number supported by the terminal equipment;

the maximum downlink carrier number or the maximum downlink secondary cell number supported by the terminal equipment;

the terminal equipment can support the maximum uplink aggregation bandwidth in each supported frequency band;

the terminal equipment can support the maximum downlink aggregation bandwidth in each supported frequency band;

the number of uplink maximum MIMO layers which can be supported by the terminal equipment in each supported frequency band;

the terminal equipment can support the maximum number of downlink MIMO layers in each supported frequency band; or the like, or, alternatively,

the type information of the terminal equipment.

For example, the overheating-related assistance information may include the maximum number of uplink secondary carriers supported by the terminal device; or, the overheating-related auxiliary information may include the maximum number of downlink secondary cells supported by the terminal device; or, the auxiliary information related to overheating may include the maximum uplink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, and the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band; or, the auxiliary information related to overheating may include the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum uplink MIMO layer number that can be supported by each serving cell on each supported frequency band, and the type information of the terminal device; alternatively, the auxiliary information related to overheating may include the maximum number of uplink secondary carriers or the maximum number of uplink secondary cells supported by the terminal device, the maximum number of downlink secondary carriers or the maximum number of downlink secondary cells supported by the terminal device, the maximum uplink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum number of uplink MIMO layers that can be supported by the terminal device in each supported frequency band, and the maximum downlink MIMO layers that can be supported by each serving cell by the terminal device in each supported frequency band, and so on. The configuration indicated by the overheating-related auxiliary information (which may be understood as the value of the parameter included in the overheating-related auxiliary information) is the configuration desired by the terminal device and is not the configuration actually supported by the capability of the terminal device, for example, the configuration indicated by the overheating-related auxiliary information may be lower than or equal to the configuration actually supported by the capability of the terminal device. It is understood that the overheating situation of the terminal device can be improved if the terminal device applies the configuration indicated by the overheating-related auxiliary information.

With reference to the first aspect or any optional implementation manner of the first aspect to the third optional implementation manner of the first aspect, in a fourth optional implementation manner of the first aspect, before releasing the first field included in the first configuration information, the method further includes:

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

For each field of the one or more fields that are included in the first configuration information and not included in the second configuration information, the terminal device may determine a requirement code corresponding to the field, and if the requirement 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, and for example, the requirement code corresponding to the first field is need M, for such a field, the terminal device may release the configuration corresponding to the field that is included in the first configuration information, that is, the terminal device may not continue to apply the configuration corresponding to the field that is included in the first configuration information. In this way, the terminal device does not need to determine the communication version corresponding to the field, and as long as one field is included in the first configuration information and is not included in the second configuration information, and the field is a field that needs to be inherited, the terminal device may release the configuration corresponding to the field included in the first configuration information, so that the terminal device does not apply the configuration corresponding to the field included in the first configuration information any longer.

Or, in this embodiment of the present application, the terminal device may also determine the communication version corresponding to the field, and then perform corresponding processing. For each of one or more fields that the first configuration information includes but the second configuration information does not include, for example, the terminal device may determine a demand code to which the field corresponds, if the requirement 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 requirement code corresponding to the first field is need M, the communication version corresponding to the first field is first version, then, for the first field, the terminal device may further determine whether the second configuration information includes other fields corresponding to the first version, or, determining whether the second configuration information includes other fields corresponding to any version higher than the first version, or, determining whether the second configuration information includes other fields corresponding to the first 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 other fields corresponding to any version higher than the first version, the terminal device may determine that the second network device can support the first version corresponding to the first field, and therefore the second configuration information does not include the first field, which may be that the second network device considers that the terminal device needs to continue to apply the configuration corresponding to the first field included in the first configuration information. Therefore, in this case, the terminal device may continue to apply the configuration corresponding to the first field included in the first configuration information without releasing the content of the first field included in the first configuration information. By determining the version, the terminal device may not release the content included in the field that can be supported by the second network device as much as possible, so that the configuration of the terminal device and the configuration of the second network device are kept consistent, and the terminal device is ensured to be capable of performing normal data communication under the second network device.

With reference to the first aspect or any one of the first to fourth alternative embodiments of the first aspect, in a fifth alternative embodiment of the first aspect, the method further comprises:

adjusting the capability of the terminal device from a first capability to a second capability, wherein the first capability is lower than the second capability, and the first capability is configured by the first network device for adapting the content of the first field.

For example, if the first network device receives the auxiliary information related to overheating from the terminal device, the first network device may 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 determines to reduce the air interface configuration of the terminal device, the first network device may determine air interface configuration information according to the received auxiliary information related to overheating, and include the air interface configuration information in an RRC reconfiguration message, and send the RRC reconfiguration message to the terminal device. After receiving the air interface configuration information, the terminal device may apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before reducing the air interface configuration, the capability of the terminal device is the second capability, and after reducing the air interface configuration, the capability of the terminal device is the first capability, and the first capability is lower than the second capability. When the terminal device needs to be switched 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, and then the second network device cannot naturally know that the terminal device has adjusted the capability according to the first field. Therefore, the terminal device can readjust the capability of the terminal device to the second capability, so that the second network device can schedule the terminal device according to the second capability, and the probability of scheduling error caused by inconsistency between the capability of the terminal device understood by the second network device and the capability actually applied by the terminal device is reduced.

In a second aspect, a second method for configuring a terminal device is provided, the method comprising: determining that a second version is lower than a first version, wherein the first version is a communication version of first network equipment, the second version is a communication version corresponding to second network equipment, the first network equipment is source network equipment for performing cell switching on terminal equipment, and the second network equipment is target network equipment for performing the cell switching on the terminal equipment; sending first information to the terminal device, where the first information is used to indicate to release a configuration corresponding to a first field, where 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 received by the terminal device does not include the first field; and sending a switching command to the terminal equipment, wherein the switching command is used for indicating switching from the first network equipment to the second network equipment.

The method may be performed by a second communication device, which may be a communication apparatus or a communication device, e.g. a chip, capable of supporting the communication apparatus to perform the functions required by the method. Illustratively, the second communication device is a network device, or a chip provided in the network device for implementing the functions of the network device, or other components for implementing the functions of the network device. In the following description, the second communication device is a network device, such as a first network device. Illustratively, the first network device is an access network device.

In this embodiment, 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, the first network device may instruct the terminal device to release all or part of the configurations corresponding to the fields that need to be inherited, so that the terminal device does not apply the configurations corresponding to the fields received before. Therefore, the fields applied by the terminal equipment and the target network equipment are kept consistent, and the terminal equipment can normally communicate under the target network equipment.

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 another version between the first version and the second version.

Because the communication version of the second network device is the second version, whether the field corresponding to the second version or the field corresponding to the other version lower than the second version is supported by the second network device, if the field is included in the configuration information and sent to the second network device by the first network device, the second network device can identify and can perform further configuration according to the field. In this way, therefore, the first network device needs to determine the specific version of the second network device and also needs to determine the version corresponding to the field, and the first network device simply instructs the terminal device to release the field corresponding to the first version and the fields corresponding to the other versions between the first version and the second version, but does not need to release the field corresponding to the second version and release the fields corresponding to the other versions lower than the second version. Therefore, the understanding of the second network device and the terminal device to the configuration information can be kept consistent, and the fields needing to be released by the terminal device are fewer, so that the workload of the terminal device can be reduced. And the second network device can also carry out further configuration on the unreleased fields which can be identified by the second network device, thereby being beneficial to reducing 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 to release a configuration corresponding to the first field, and the method includes:

the first information comprises the first field, and the content of the first field is used for indicating that the configuration corresponding to the first field is released; alternatively, the first and second electrodes may be,

the first information is first indication information, the first indication information is used for indicating to release configuration corresponding to one or more fields, the one or more fields include the first field, and each field of the one or more fields is a field in which the terminal device needs to keep 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 that the corresponding field is released. For example, the configuration information previously configured by the first network device to the terminal device includes a first field, and then the first information also includes the first field, and the content of the first field is first content, where the first content is used to indicate to release the configuration corresponding to the first field, or to indicate to release 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 content of the first field included in the configuration information from the first network device before stored at the terminal device side is released, so that the configuration corresponding to the first field included in the configuration information is not applied any more. In this embodiment, it is equivalent to that the first network device resends the new configuration information to the terminal device to indicate that all or part of the fields included in the original configuration information need to be inherited to be released. The indication mode is more specific 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, referred to as first indication information, and the first indication information may occupy one or more bits. The first indication information may indicate that a configuration corresponding to one or more fields, for example, one of the one or more fields, is released. The one or more fields are all fields that need to be inherited, and the one or more fields are all or part of fields that need to be inherited included in the configuration information that is configured to the terminal device by the first network device before, that is, the first indication information is used for indicating to release all or part of fields that need to be inherited included in the configuration information. After the terminal device receives the first indication information, the terminal device may release all or part of the contents of the fields that need to be inherited, which are stored in the terminal device side and are included in the configuration information from the first network device before, so that the configuration corresponding to the fields included in the configuration information is not applied any more. For example, the field released by the terminal device includes a first field. In this embodiment, the first network device does not need to retransmit new configuration information to the terminal device, but only needs to transmit the first indication information to the terminal device to indicate that the corresponding field is released. Compared with the configuration information, the information amount of the first indication information is small, and transmission overhead is saved.

With reference to the second aspect or the first alternative implementation of the second aspect or the second alternative implementation of the second aspect, in a third alternative implementation of the second aspect, the method further comprises:

and sending first configuration information to the second network equipment, wherein the first configuration information comprises a field configured for the terminal equipment by the first network equipment, and the first configuration information does not comprise the first field.

For example, the first network device may obtain the first configuration information according to configuration information previously configured to the terminal device by the first network device. For example, the first network device deletes all or part of fields that need to be inherited from the configuration information configured to the terminal device, and the configuration information obtained thereby may be the first configuration information. These fields which the first network device deletes from the configuration information previously configured to the terminal device, i.e. the fields which the first network device indicates to the terminal device that release is required. After the second network device obtains the first configuration information, the terminal device may be configured according to the first configuration information. Since the first configuration information does not include the field which is unrecognizable by the second network device and needs to be inherited, the second network device can normally configure the terminal device.

With reference to the second aspect or the first alternative implementation manner of the second aspect or the second alternative implementation manner of the second aspect, in a third alternative implementation manner of the second aspect,

with reference to the second aspect or any one of the first optional implementation manner of the second aspect to the third optional implementation manner of the second aspect, in a fourth optional implementation manner of the second aspect, the first field includes overheating configuration information.

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

second indication information for indicating whether the overheating-related auxiliary information can be sent to the network device; and/or the presence of a gas in the gas,

With reference to the fifth alternative implementation manner of the second aspect, in a sixth alternative implementation manner of the second aspect, the overheating-related auxiliary information includes one or more of the following:

the type information of the terminal equipment.

With reference to the second aspect or any one of the first optional implementation manner of the second aspect to the sixth optional implementation manner of the second aspect, in a seventh optional implementation manner of the second aspect, the method further comprises:

receiving version indication information from the second network device, where the version indication information is used to indicate that the communication version of the second network device is the second version.

The second network device may send the version indication information to the first network device, so that the first network device can clarify the communication version of the second network device for subsequent related operations.

With reference to the second aspect or any one of the first optional implementation manner of the second aspect to the seventh optional implementation manner of the second aspect, in an eighth optional implementation manner of the second aspect, the method further comprises:

receiving configuration indication information from the second network device, where the configuration indication information is used to indicate that the second network device does not use a full configuration mode to configure the terminal device, and the full configuration mode is a mode in which all fields to be configured to the terminal device are reconfigured.

In this embodiment of the application, the configuration mode applied by the second network device is a relay-oriented configuration mode, or an iterative configuration mode, that is, a subsequent configuration needs to be performed based on a previous configuration, for example, the second configuration information is determined based on the first configuration information of the first network device, that is, the second configuration information is not configured in a full-configuration mode. In practical application, the second network device may also adopt a full configuration mode, where the full configuration mode is a mode in which all fields to be configured to the terminal device are all reconfigured. With regard to the manner of full configuration, reference may be made to the related description of the embodiment shown in fig. 5. The embodiment of the present application does not limit the configuration mode adopted by the second network device, but if the second network device adopts a full configuration mode, it is not necessary for the first network device to instruct the terminal device to release the field that needs to be inherited. Therefore, as an optional implementation, the second network device may send the configuration indication information to the first network device, and the first network device may receive the configuration indication information from the second network device. The configuration indication information may indicate that the second network device does not configure the terminal device in a full configuration manner, so that the first network device may perform subsequent related operations.

With regard to the technical effects brought about by some embodiments of the second aspect, reference may be made to the introduction of the technical effects of the respective embodiments of the first aspect.

In a third aspect, a third method for configuring a terminal device is provided, the method comprising: sending version indication information to a first network device, wherein the version indication information is used for indicating a second version, and the second version is a communication version of a second network device; receiving first configuration information from the first network device, where the first configuration information includes a field configured for a terminal device by the first network device, and the first configuration information does not include a first field, the first network device is a source network device for performing cell handover for the terminal device, and the second network device is a target network device for performing the cell handover for the terminal device, where 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 received by the terminal device does not include the first field.

The method may be performed by a third communication device, which may be a communication apparatus or a communication device, such as a chip, capable of supporting a communication apparatus to implement the functions required by the method. Illustratively, the third communication device is a network device, or a chip provided in the network device for implementing the function of the network device, or other components for implementing the function of the network device. In the following description, the third communication device is a network device, such as the second network device. Illustratively, the second network device is an access network device.

For example, the transceiver module may include a transmitting module and a receiving module, and the transmitting module and the receiving module may be different functional modules, or may also be the same functional module, but can implement different functions. Illustratively, the first communication device is a communication device, or a chip or other component provided in the communication device. Illustratively, the communication device is a terminal device. In the following, the first communication apparatus is exemplified as a terminal device.

The foregoing has described some of the noun concepts to which embodiments of the present application relate, and the following has described some features of the embodiments of the present application.

After the terminal device is accessed to the network device, the network device needs to issue the 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 normally perform data communication under the network device. Referring to fig. 1, a flowchart of configuring a terminal device for a network device is shown.

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

Illustratively, the configuration message may be a Radio Resource Control (RRC) reconfiguration (RRC reconfiguration) message, or an RRC setup (RRC setup) message, or an RRC reestablishment (RRC reestablishment) message, or an RRC recovery (RRC resume) message, etc. The configuration message may include parameters configured by the network device for the terminal device, and for example, the configured parameters may include: one or more of a configuration parameter of a radio bearer, a physical layer (PHY) parameter, a Medium Access Control (MAC) parameter, a Radio Link Control (RLC) parameter, or a security parameter.

The network device may send the configuration message to the terminal device multiple times, and therefore, the configuration message sent at a certain time may be further configured based on the previous configuration message, that is, the network device adopts a relative configuration (delta configuration) manner. Specifically, the configuration message may include one or more IEs, each IE being a field or a field, an IE may be understood as a parameter, or an IE may be understood as including a parameter. In the configuration message, each IE may correspond to a corresponding requirement code (need codes), and the requirement codes corresponding to different IEs may be the same or different. With respect to the demand code, reference is made to the introduction of table 1.

TABLE 1

Table 1 lists 4 demand codes. For example, if the requirement code corresponding to a field is requirement code R (i.e., need R), the field is a field that needs to be inherited, and the parameters configured by the field can be regarded as non-disposable parameters. That is, if the terminal device has received the field before, but does not receive the field this time, the terminal device needs to release the configuration corresponding to the field received before, that is, the terminal device does not continue to apply the configuration corresponding to the field received before. If the terminal device has received the field before and this time, the terminal device needs to apply the configuration corresponding to the field received this time.

For another example, if the requirement code corresponding to a field is requirement code M (i.e., need M), the field is a field that needs to be inherited, and the parameter configured by the field can be regarded as a non-disposable parameter. That is, if the terminal device has received the field before, but does not receive the field this time, the terminal device needs to continue to apply the configuration corresponding to the field received before, that is, to continue to apply the parameters included in the field received before. If the terminal device has received the field before and this time, the terminal device needs to apply the configuration corresponding to the field received this time.

For example, the network device first sends a configuration message 1 to the terminal device, where the configuration message 1 includes IE1, IE2, and IE3, where a requirement code corresponding to IE1 is need M, and requirement codes corresponding to IE2 and IE3 are need R, and the terminal device applies a configuration corresponding to IE1, a configuration corresponding to IE2, and a configuration corresponding to IE 3. The network device then sends a configuration message 2 to the terminal device, the configuration message 2 being further configured according to the configuration message 1. For example, the configuration message 2 includes IE2 and IE4, and the requirement code corresponding to IE4 is requirement code N. Because the configuration message 2 re-issues the IE2, the terminal device applies the configuration corresponding to the IE2 included in the configuration message 2, and the configuration message 2 newly issues the IE4, the terminal device applies the configuration corresponding to the IE4 included in the configuration message 2. In addition, configuration message 2 does not include IE1, but configuration message 1 includes IE1, and the requirement code corresponding to IE1 is need M, so that the terminal device continues to apply the configuration corresponding to IE1 included in configuration message 1. The configuration message 2 does not include the IE3, and the requirement code corresponding to the IE3 is need R, so that the terminal device releases the configuration corresponding to the IE3 included in the configuration message 1, that is, the terminal device does not apply the configuration corresponding to the 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 normally perform data communication under the current network device.

In addition, the terminal device may overheat during use. Then, when the terminal device has the problem of overheating inside the device, the temperature can be reduced by reducing the capacity or configuration of the terminal device, so as to solve the overheating problem. In order to reduce the capability or configuration of the terminal device, the terminal device may send UE assistance information (UE assistance information) to the network device, where the UE assistance information is overheating assistance information, so as to notify the network device of the capability or configuration that the terminal device desires to reduce, for reference by the network device to perform reconfiguration. The terminal device needs to send the UE assistance information to the network device, and the network device needs to send the over-temperature configuration information to the terminal device first, so that the terminal device can send the UE assistance information to the network device. The overheating configuration information sent by the network device to the terminal device may be included in a configuration message sent by the network device to the terminal device, for example, the configuration message shown in S11 in the flow shown in fig. 1. Referring to fig. 2, a procedure of sending UE assistance information from a terminal device to a network device will be described.

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, which may include over-temperature configuration information. The overheating configuration information includes, for example, information indicating whether the terminal device is capable of sending the overheating assistance information to the network device, and a value of an overheating-related prohibition timer. The method comprises the steps that a prohibition timer is used for controlling the frequency of reporting the overheating auxiliary information by the terminal equipment by the network equipment, the prohibition timer needs to be synchronously started by the terminal equipment and the network equipment after the terminal equipment reports the overheating auxiliary information once, and in the running process of the prohibition timer, the terminal equipment cannot report the overheating auxiliary information again and can only report the overheating auxiliary information again when the prohibition timer is overtime or after the overtime. The value of the prohibit timer specified in the existing protocol may be selected from a range of { s0, s0dot5, s1, s2, s5, s10, s20, s30, s60, s90, s120, s300, s600, spark 3, spark 2, spark 1}, where s represents a unit of seconds, e.g., s0 represents 0 seconds, and s1 represents 1 second. s0dot5 represents 0.5 seconds, free (spare) represents a reserved bit, e.g. spare3, spare2 and spare represent three reserved bits.

The overheating configuration information sent by the network device to the terminal device may be included in one or more IEs, and the requirement code corresponding to the one or more IEs may be a need M.

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

If the overheating configuration information sent by the network device is used for configuring that the terminal device can send auxiliary information related to overheating, when the terminal device has an overheating problem, the terminal device may send the overheating auxiliary information to the network device. Or, if the overheating configuration information sent by the network device is used to configure that the terminal device is capable of sending auxiliary information related to overheating, when the terminal device has an overheating problem and the prohibit timer is not in an operating state, the terminal device may send the overheating auxiliary information to the network device. For example, the terminal device may send the overheating assistance information to the network device in a UE assistance information message.

In the scenarios such as NR independent networking, NR-DC or NE-DC, the overheating auxiliary information that can be reported by the terminal device may include one or more of the following: the number of uplink maximum secondary (CC) carriers or the number of uplink maximum secondary cells (scells) supported by the terminal device, the number of downlink maximum secondary carriers or the number of downlink maximum secondary cells supported by the terminal device, the maximum uplink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the number of uplink maximum MIMO layers (layer) that can be supported by each serving cell of the terminal device in each supported frequency band, or the maximum downlink MIMO layers that can be supported by each serving cell of the terminal device in each supported frequency band. In (NG) EN-DC scenarios, the overheating assistance information that can be reported by the terminal device includes: the type of 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 may decide whether to reduce the air interface configuration of the terminal device, thereby alleviating the overheating problem of the terminal device. How to decide depends on the internal implementation of the network device. If the network device determines to reduce the air interface configuration of the terminal device, the network device may determine configuration information according to the received overheating assistance information, and send the configuration information to the terminal device by including the configuration information in the RRC reconfiguration message, and the terminal device may reduce the air interface configuration of the terminal device by applying the configuration information. After the terminal device communicates using the reduced air interface configuration, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the overheating problem.

Since some terminal devices are in a mobile state, such as a mobile phone, the terminal device may be involved in performing cell handover. A cell handover may include an intra-base station cell handover and a cross-base station cell handover, where a cross-base station cell handover refers to a handover to another communication connection when a terminal device moves from a coverage area of one base station (a source base station) to a coverage area of another base station (a target base station) so that the terminal device continues to maintain a 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 may be understood as "cell handover across base stations". For example, referring to fig. 3, a schematic diagram of cell handover for a terminal device is shown. As can be seen from fig. 3, the terminal device needs to be handed over from the source base station to the target base station. In addition, please refer to fig. 4 again, which is a flowchart of a cell handover process, and the operation of the core network side is not shown in fig. 4.

S41, the source base station sends a 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 handover of the terminal device from the source base station to the target base station.

Before the terminal device performs cell handover, that is, before performing S41, the source base station may issue configuration information, for example, referred to as configuration information 1, to the terminal device, where the configuration information 1 may include one or more IEs, and the configuration information 1 is used for the terminal device to communicate under the source base station.

During the cell switching process, the source base station will send configuration information 1 to the target base station. For example, the source base station may transmit configuration information 1 to the target base station included in the handover preparation information message.

And S42, the target base station performs admission control. That is, the target base station determines whether to allow the terminal device to handover 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 command message to the source base station, and the source base station receives the handover command message from the target base station.

The handover control message may indicate to the target base station that the terminal device is allowed 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 handover from the source base station to the target base station.

In the cell handover process, the target base station may also issue configuration information to the terminal device, for example, the configuration information 2 is called configuration information 2, the configuration information 2 may include one or more IEs, the configuration information 2 is used for the terminal device to communicate under the target base station, and 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 of S43 to send to the source base station, and the source base station may further include the configuration information 2 in the RRC reconfiguration message of S44 to send to the terminal device.

S45, the terminal device performs a handover operation to handover from the source base station to the target base station, or to 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 RRC reconfiguration complete may indicate that the terminal device has completed the handover.

Through the flow shown in fig. 4, the terminal device completes the cell handover process. The configuration information 2 may be applied after the terminal device is handed over to the target base station.

The communication versions supported by the various base stations may differ, and thus the communication versions of the source base station and the target base station may differ. For example, the communication version of the source base station may be higher than the communication version of the target base station. Since the high-version base station supports more functions than the low-version base station, the high-version base station can configure more IEs, but the low-version base station does not have new functions, and therefore cannot identify IEs corresponding to the new functions. The target base station cannot identify these IEs, and therefore these IEs are not sent to the terminal device. However, if some IEs have a required code of need M, for example, an IE including over-temperature configuration information, then if the terminal device has received the IE last time but has not received the IE this time, it indicates that the terminal device needs to continue to apply the configuration corresponding to the IE received last time. For such an IE, if the terminal device determines that the IE is sent by the source base station to the terminal device and the IE is not sent by the target base station 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 identify the IE, and naturally cannot support the configuration corresponding to the IE, which may cause that the terminal device cannot normally communicate 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 has received the first field last time but has not received the first field this time, the terminal device needs to continue to apply the configuration corresponding to the first field received last time, or the requirement code corresponding to the first field is the need M. Then, in this embodiment of the application, if it is determined 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 may release the configuration corresponding to the first field included in the first configuration information, that is, the terminal device does not apply the configuration corresponding to the first field received before. The second network device does not send the first field to the terminal device, possibly because the second network device cannot recognize the first field, the terminal device releases the configuration corresponding to the first field, so that the fields applied by the terminal device and the second network device are kept consistent, and the terminal device can normally communicate under the second network device.

For example, when a user holds a smartphone while walking for a call service, the smartphone may perform a cell handover due to the movement of the user. Due to the above problems, the smart phone may not be able to communicate normally when being switched to the target base station, that is, the smart phone may have situations such as poor call signal, call interruption, or call drop, which affect the user experience. By adopting the scheme provided by the embodiment of the application, the problems can be solved. For example, after the solution provided in the embodiment of the present application is adopted, for example, a user holds a smartphone while walking to perform a call service, the smartphone may perform cell switching due to movement of the user, but in the embodiment of the present application, even if the smartphone is switched to a target base station, since an actual configuration of the smartphone and a configuration of the smartphone known by the target base station can be kept as consistent as possible, the smartphone can normally communicate in the target base station. That is to say, by adopting the technical scheme provided by the embodiment of the application, the probability of situations such as poor call signal, call interruption or call drop after the cell switching of the smart phone can be reduced, the communication quality is improved, and the user experience is also improved.

The technical solution provided in the embodiment of the present application may be applied to a fourth generation mobile communication technology (4G) system, such as an LTE system, or may be applied to a 5G system, such as an NR system, or may also be applied to a next generation mobile communication system or other similar communication systems, which is not limited specifically. In addition, the technical solution provided by the embodiment of the present application may be applied to a device-to-device (D2D) scenario, such as an NR-D2D scenario, or may be applied to a vehicle-to-everything (V2X) scenario, such as an NR-V2X scenario, for example, may be applied to a vehicle networking, such as a V2X scenario, a vehicle-to-vehicle (V2V) scenario, or may be applied to the fields of smart driving, assisted driving, or smart internet vehicles, and the like.

An application scenario of an embodiment of the present application may continue with reference to fig. 3. The base station in fig. 3 may be an access network device. The access network device corresponds to different devices in different systems, for example, in a 4G system, the access network device may correspond to an eNB, and in a 5G system, the access network device in a 5G system, for example, a gNB. Of course, the technical solution provided in the embodiment of the present application may also be applied to a future mobile communication system, and therefore the access network device may also correspond to a network device in the future mobile communication system. Fig. 3 illustrates that the access network device is a base station, and actually, referring to the foregoing description, the access network device may also be an RSU or the like.

The method provided by the embodiment of the application is described below with reference to the accompanying drawings. It should be noted that, in the embodiments of the present application, all information interaction related to between the terminal device and the core network device may be forwarded from the access network device, but since the solution of the embodiments of the present application does not relate to the core network device, it is not mentioned below. In addition, the configuration information, for example, the first configuration information, the second configuration information, the third configuration information, or the fourth configuration information, described in the embodiments of the present application, may include parameters configured by the network device for the terminal device, so that the terminal device can operate under the network device. For example, the parameters configured by the network device for the terminal device may include one or more of configuration parameters of a radio bearer, physical layer parameters, MAC parameters, RLC parameters, or security parameters, or may further 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 the method. In the following description, the method is applied to the network architecture shown in fig. 3 as an example.

For ease of description, in the following, the method is performed by a network device and a terminal device as an example. The first network device described below is a source network device of the terminal device, that is, a network device accessed by the terminal device before cell handover is performed, and the second network device described below is a target network device of the terminal device, that is, a network device accessed by the terminal device after cell handover is performed. The terminal device described below may be a terminal device in the network architecture shown in fig. 3, the first network device described below may be a source base station in the network architecture shown in fig. 3, and the second network device described below may be a target base station in the network architecture shown in fig. 3.

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

For example, the first network device as the source network device may send the third configuration information to the terminal device before the cell handover. For example, the first network device may send the third configuration information to the terminal device when the terminal device is just accessing the network (e.g., when a random access is completed with the first network device), and after that, when the terminal device operates under the first network device, the first network device does not send any other configuration information to the terminal device; or, the first network device may send the configuration information to the terminal device when the terminal device is just accessing the network (for example, when a random access is completed with the first network device), and after that, when the terminal device operates under the first network device, the first network device may also send new configuration information to the terminal device, so that for the first network device and the terminal device, the currently applied configuration information may be obtained according to the new configuration information and the previous configuration information, where in this case, for example, the third configuration information is the configuration information that the first network device has sent to the terminal device last time. Or, the first network device may also send the third configuration information to the terminal device in the cell handover process. For example, as known from the cell handover procedure described above, in the cell handover procedure, the source network device may send a handover command (the handover command is, for example, an RRC reconfiguration message in S44 in the flow shown in fig. 4) to the terminal device to instruct the terminal device to perform handover, and then the first network device may send the third configuration information to the terminal device in the handover command.

As described above, the current configuration process is iterative configuration, or legacy configuration, that is, the next configuration is performed based on the previous configuration. Then, for example, the third configuration information is the configuration information that was last sent to the terminal device by the first network device, or, in other words, the first network device has sent other configuration information, for example, the fourth configuration information, to the terminal device before sending the third configuration information to the terminal device, then the third configuration information is further configured based on the fourth configuration information, and therefore, the terminal device may determine the configuration information applied by the terminal device according to the third configuration information and the fourth configuration information, and refer to the configuration information as the first configuration information. The terminal device may perform configuration by using the first configuration information, so that the terminal device may perform data communication normally under the first network device.

The first configuration information may comprise one or more fields, e.g. an IE, or a field, or may be other concepts, it being understood that a field comprises one or more bits (bits). Each field of the fields included in the third configuration information may correspond to a requirement code, and the requirement codes corresponding to different fields may be the same or different. In addition, each field may include a parameter. For example, the first configuration information may include a first field, which includes, for example, a parameter or, in other words, corresponding information. For the terminal device, if the first field is not received, the content of the first field received last time needs to be inherited (or applied), or the configuration corresponding to the content of the first field received last time needs to be continuously applied, or the first parameter needs to be continuously applied. For example, if the requirement 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 over-temperature configuration information, or the first field may include other information as well.

The overheating configuration information includes, for example, the first indication information, or includes a timing length of the prohibition timer, or includes the first indication information and the timing length of the prohibition timer. Wherein the first indication information is usable to indicate whether the overheating-related auxiliary information can be sent to the network device. The prohibit timer is an overheating-related prohibit timer that may be used to control the frequency with which the terminal device sends overheating-related assistance information 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 overheating-related auxiliary information can be sent to the network device, the terminal device may send the overheating-related auxiliary information to the network device, and the terminal device starts the prohibition timer when sending the overheating-related auxiliary information or after sending the overheating-related auxiliary information, and similarly, the network device also starts the prohibition timer when receiving the overheating-related auxiliary information or after receiving the overheating-related auxiliary information. During the running time of the prohibit 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 overheating to the network device when or after the prohibit timer expires. For example, the value range of the timing duration of the prohibit timer may be { s0, s0dot5, s1, s2, s5, s10, s20, s30, s60, s90, s120, s300, s600, spark 3, spark 2, spark 1}, and reference is made to the related description of this range.

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 first indication information indicating that the overheating-related auxiliary information can be transmitted to the network device, the terminal device may transmit the overheating-related auxiliary information to the first network device if an overheating problem occurs in the terminal device. Alternatively, if the overheating configuration information includes the first indication information and the timing duration of the prohibit timer, the terminal device may send the overheating-related auxiliary information to the first network device if the terminal device has an overheating problem and the prohibit timer is not in an operating state. For example, the terminal device may send the overheating-related assistance information to the first network device in a UE assistance information message.

In embodiments of the present application, the superheat-related auxiliary information may include one or more of: the number of uplink maximum auxiliary carriers or the number of uplink maximum auxiliary cells supported by the terminal device, the number of downlink maximum auxiliary carriers or the number of downlink maximum auxiliary cells supported by the terminal device, the uplink maximum aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the downlink maximum aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the number of uplink maximum MIMO layers that can be supported by each serving cell on each supported frequency band by the terminal device, the number of downlink maximum MIMO layers that can be supported by each serving cell on each supported frequency band by the terminal device, or the type information of the terminal device. For example, the overheating-related assistance information may include the maximum number of uplink secondary carriers supported by the terminal device; or, the overheating-related auxiliary information may include the maximum number of downlink secondary cells supported by the terminal device; or, the auxiliary information related to overheating may include the maximum uplink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, and the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band; or, the auxiliary information related to overheating may include the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum uplink MIMO layer number that can be supported by each serving cell on each supported frequency band, and the type information of the terminal device; alternatively, the auxiliary information related to overheating may include the maximum number of uplink secondary carriers or the maximum number of uplink secondary cells supported by the terminal device, the maximum number of downlink secondary carriers or the maximum number of downlink secondary cells supported by the terminal device, the maximum uplink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum downlink aggregation bandwidth that can be supported by the terminal device in each supported frequency band, the maximum number of uplink MIMO layers that can be supported by the terminal device in each supported frequency band, and the maximum downlink MIMO layers that can be supported by each serving cell by the terminal device in each supported frequency band, and so on.

It should be noted that the configuration indicated by the overheating-related auxiliary information (it is understood that the value of the parameter included in the overheating-related auxiliary information) is the configuration expected by the terminal device, and is not the configuration that can be actually supported by the capability of the terminal device, for example, the configuration indicated by the overheating-related auxiliary information may be lower than or equal to the configuration that can be actually supported by the capability of the terminal device. It is understood that the overheating situation of the terminal device can be improved if the terminal device applies the configuration indicated by the overheating-related auxiliary information. 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 on each supported frequency band, where the number of MIMO layers is, for example, 2, which indicates that the terminal device expects the first network device to configure the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device on each supported frequency band as 2, but the maximum number of uplink MIMO layers that can actually be supported by the terminal device on each supported frequency band may be 4, that is, the terminal device expects to reduce the number of MIMO layers to improve the overheating condition of the terminal device.

As described herein, each frequency band supported by the terminal device includes, for example, two frequency bands of a high frequency (FR2) and a 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. Since the cell handover procedure is not yet involved at this time, the RRC reconfiguration message is not the RRC reconfiguration message in S44 in the flow shown in fig. 4.

If the first network device receives the auxiliary information related to overheating from the terminal device, the first network device may decide whether to reduce the air interface configuration of the terminal device, thereby alleviating the overheating problem of the terminal device. How to decide depends on the internal implementation of the first network device. If the first network device determines to reduce the air interface configuration of the terminal device, the first network device may determine air interface configuration information according to the received auxiliary information related to overheating, and include the air interface configuration information in an RRC reconfiguration message, and send the RRC reconfiguration message to the terminal device. After receiving the air interface configuration information, the terminal device may apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before reducing the air interface configuration, the capability of the terminal device is the second capability, and after reducing the air interface configuration, the capability of the terminal device is the first capability, and the first capability is lower than the second capability. The second capability may be, for example, the maximum capability actually supported by the terminal device, or may be lower than the maximum capability actually supported by the terminal device. After the terminal device communicates using the reduced air interface configuration, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the overheating problem. Or, if the first network device determines not to decrease 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, S53 may not need to be executed.

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 the same. For example, the auxiliary information related to overheating includes the maximum uplink MIMO layer number that can be supported by each serving cell on each frequency band supported by the terminal device, and the air interface configuration information also includes the maximum uplink MIMO layer number that can be supported by each serving cell on each frequency band supported by the terminal device. In this case, the values of the parameters included in the air interface configuration information and the values of the parameters included in the auxiliary information related to overheating may be the same or different. For example, the maximum number of uplink MIMO layers that can be supported by each serving cell of the terminal device on each supported frequency band included in the auxiliary information related to overheating is 2, and the maximum number of uplink MIMO layers that can be actually supported by each serving cell of the terminal device on each supported frequency band is 4. Then, the maximum number of uplink MIMO layers that can be supported by each serving cell on each frequency band supported by the terminal device included in the air interface configuration information may be 2 or may also be 3. That is, the first network device may determine the air interface configuration information completely according to the auxiliary information related to overheating, or the first network device may also consider other factors when determining the air interface configuration information, so that the determined air interface configuration information is not completely identical to the suggestion of the auxiliary information related to overheating.

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 overheating-related auxiliary information includes the maximum number of uplink MIMO layers that can be supported by the terminal device per serving cell on each supported frequency band, and the air interface configuration information may not include the parameter but include the maximum number of uplink secondary carriers supported by the terminal device. As can be seen, the first network device has certain flexibility in determining the air interface configuration information.

Wherein, both S52 and S53 are optional steps, not necessarily performed, and are indicated by dashed lines in fig. 5.

S54, in 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 as described in S41 in the flow shown in fig. 4 and send the third configuration information to the second network device, or may also include the third configuration information in other messages and send the third configuration information to the second network device.

After receiving the third configuration information, the second network device may determine second configuration information according to the third configuration information, where the second configuration information may be used for communication of the terminal device in the second network device. For example, for some fields included in the third configuration information, the second network device may reconfigure the contents of the fields (for example, reconfigure values of parameters included in the fields), or may not reconfigure the fields and continue to use the contents of the fields included in the third configuration information. For example, for a field whose corresponding requirement code is 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 after receiving the second configuration information, the terminal device may apply the configuration corresponding to the field included in the second configuration information; if the second network device considers that the content of the field does not need to be configured, 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, the terminal device finds that the second configuration information does not include the field, and the first configuration information includes the field, the terminal device continues to apply the configuration corresponding to the field included in the first configuration information. For the fields corresponding to other requirement codes, the second network device may be configured according to the characteristics of the corresponding requirement codes, and similarly, for the fields, the second network device may select reconfiguration, or may continue to use the configuration corresponding to the field included in the third configuration information.

For example, the communication version of the first network device is version 1, the communication version of the second network device is version 2, for example, version 1 is v1540, version 2 is v1520, and the like. If version 1 is higher than version 2, then for one or more fields included in the third configuration information, if some of the fields correspond to version 1, or to other versions between version 1 and version 2, and do not correspond to version 2, nor to any other versions lower than version 2, then the second network device cannot recognize these fields, or cannot interpret these fields. That is, a network device cannot identify fields corresponding to communication versions that are higher than the network device supports. For fields that are not recognizable 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 accordingly, 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 transmit the second configuration information to the first network device in a handover control message as described in S43 of the flow shown in fig. 4, and the first network device may transmit the second configuration information to the terminal device in an RRC reconfiguration message as described in S44 of the flow shown in fig. 4. S51 describes that the first network device may send the third configuration information to the terminal device before performing cell handover, or send the third configuration information to the terminal device through an RRC reconfiguration message during cell handover. Then, if the first network device transmits the third configuration information to the terminal device through the RRC reconfiguration message and transmits the second configuration information to the terminal device through the RRC reconfiguration message, the third configuration information and the second configuration information are transmitted through one message.

S56, the terminal device determines that the first configuration information includes the first field and that the second configuration information does not include the first field. Alternatively, for some fields, if the content included in the field is empty, the effect is the same as if the field is not included, i.e., if the field is included in the configuration information but the content of the field is empty, the configuration information may also be considered as not including the field. For such fields, S56 may 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 null. The embodiment of the application mainly takes the example that the terminal device determines that the first configuration information includes the first field and the second configuration information does not include the first field.

The first field is a field that needs to be inherited, and for this reason, when the terminal device does not receive the first field, the terminal device needs to inherit the content of the first field that was received last time, or in other words, the terminal device needs to continue to apply the configuration corresponding to the first field that was received last time. Or that the first field is a field that the terminal device needs to keep the content of the last received first field when the configuration information (e.g., the second configuration information) newly received by the terminal device does not include the first field. For example, the requirement code corresponding to the first field is need M.

Since the second configuration information is a further configuration based on the first configuration information, the terminal device may compare the second configuration information with the first configuration information after receiving the second configuration information to determine the configuration information that should actually be applied. For example, if the second network device cannot identify a portion of the fields included in the first network device, the second configuration information may not include the portion of the fields. And there may be fields (for example, the first field) that need to be inherited, and since the second configuration information does not include such fields, the terminal device may continue to apply the configuration corresponding to such fields included in the first configuration information. However, the configuration corresponding to such a field is not supported by the second network device, and if the terminal device continues to apply the configuration corresponding to such a field included in the first configuration information, a problem may occur in communication of the terminal device under the second network device, for example, the terminal device may not perform normal data communication with the second network device. Thus, in the embodiment of the present application, the terminal device may determine a field that the first configuration information includes but the second configuration information does not include, for example, the terminal device may determine one or more fields that may include the first field. If the same field has the same identifier, 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 releases the content of the first field included in the first configuration information.

For each field of the one or more fields that are included in the first configuration information and not included in the second configuration information, the terminal device may determine a requirement code corresponding to the field, and if the requirement code corresponding to the field indicates that the field is a field that does not need to be inherited, for example, the requirement code of the field is need N, the terminal device may not take a corresponding action; or, if the requirement code of the field is need R, the terminal device may release the configuration corresponding to the field. Or, if the requirement 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 requirement code corresponding to the first field is a need M, for such a field, the terminal device may release the configuration included in the first configuration information corresponding to the field, that is, the terminal device does not continue to apply the configuration included in the first configuration information corresponding to the field. In this way, the terminal device does not need to determine the communication version corresponding to the field, and as long as one field is included in the first configuration information and is not included in the second configuration information, and the field is a field that needs to be inherited, the terminal device may release the configuration corresponding to the field included in the first configuration information, so that the terminal device does not apply the configuration corresponding to the field included in the first configuration information any more, which may be understood as that the terminal device releases the configuration corresponding to the field.

For example, the first field includes the over-temperature configuration information, and the requirement code corresponding to the first field is need M. The first field is included in the first configuration information but not in the second configuration information. The terminal device may release the contents of the first field included in the first configuration information so that the terminal device does not apply 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 unrecognizable by the second network device. 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 normally communicate with 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 is correspondingly consistent with the configuration of the terminal device understood by the second network device, and it is ensured that the terminal device can normally perform data communication under the second network device.

Or, in this 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 one field), and then perform corresponding processing. For example, for each field of the one or more fields that are included in the first configuration information and not included in the second configuration information, the terminal device may determine a requirement code corresponding to the field, and if the requirement code corresponding to the field indicates that the field is a field that does not need to be inherited, for example, the requirement code of the field is needn, the terminal device may not take a corresponding action; or, if the requirement code of the field is need R, the terminal device may release the configuration corresponding to the field. Or, if the requirement 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 requirement code corresponding to the first field is a need M, and the communication version corresponding to the first field is a first version, for the first field, the terminal device may further determine whether the second network device can support the first version. For example, the manner in which the terminal device determines 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 (e.g., the terminal device may determine the communication version corresponding to one or more fields included in the second information other than the first field to determine whether there are fields corresponding to the first version in the fields, if so, determine that the second configuration information includes other fields corresponding to the first version, and if not, determine that the second configuration information does not include other fields corresponding to the first version), or whether the second configuration information includes other fields corresponding to any version higher than the first version (in a manner similar to the manner in which it is determined whether the second configuration information includes other fields corresponding to the first version), or, determining whether the second configuration information includes other fields corresponding to the first 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 other fields corresponding to any version higher than the first version, the terminal device may determine that the second network device can support the first version corresponding to the first field, and therefore the second configuration information does not include the first field, which may be that the second network device considers that the terminal device needs to continue to apply the configuration corresponding to the first field included in the first configuration information. Therefore, in this case, the terminal device may continue to apply the configuration corresponding to the first field included in the first configuration information without releasing the content of the first field included in the first configuration information. By determining the version, the terminal device may not release the content included in the field that can be supported by the second network device as much as possible, so that the configuration of the terminal device and the configuration of the second network device are kept consistent, and the terminal device is ensured to be capable of performing normal data communication under the second network device.

Or, if the second configuration information does not include other fields corresponding to the first version nor other fields corresponding to any version higher than the first version, the terminal device may not determine whether the second network device supports the first version corresponding to the first field, 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, a problem may occur in communication of the terminal device under the second network device, for example, the terminal device may not 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 field first configuration information, and no longer continue to apply the configuration corresponding to the first field included in the first configuration information. By the method, the configuration of the terminal equipment is consistent with that of the second network equipment, and the terminal equipment can carry out normal data communication under the second network equipment.

For example, if the first configuration information of the terminal device in the first network device includes the overheating configuration information (e.g., other configuration (OtherConfig) -v1540 or overheating assistance configuration (overheating assistance config)), for example, the overheating configuration information is included in the first field, and the first field is, for example, an IE. If the second configuration information received by the terminal device does not contain the first field, the terminal device may determine whether the second configuration information includes a field corresponding to the v1540 version or 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 the v1540 version, it indicates that the second network device can support the v1540 version, or can support other versions higher than the v1540 version, the second network device can also support the first field, and at this time, the terminal device may continue to apply the overheating configuration information included in the first configuration information without releasing the content of the first field included in the first configuration information, that is, without releasing the overheating configuration information. Alternatively, if the second configuration information includes neither a field corresponding to the v1540 version nor any other version higher than the v1540 version, the terminal device cannot determine the communication version of the second network device, nor whether the second network device can support the communication version corresponding to the first field. In this case, for the sake of insurance, the terminal device may release the overheating configuration information included in the first configuration information and no longer apply the overheating configuration information.

And S58, the terminal device adjusts the capability of the terminal device from the first capability to the second capability. Wherein the first capacity is lower than the second capacity.

S58 may be performed if S53 is performed and the terminal device has adjusted the capability of the terminal device, or S58 need not be performed if the terminal device has not adjusted the capability of the terminal device. Thus, S58 is an optional step, represented by the dashed line in fig. 5. In S53, after receiving the air interface configuration information, the terminal device may apply the air interface configuration information to reduce the air interface configuration of the terminal device. For example, before reducing the air interface configuration, the capability of the terminal device is the second capability, and after reducing the air interface configuration, 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 reducing the air interface configuration, if the number of antennas of the terminal device is 4, the second capability is 4 antenna capability, and after reducing the air interface configuration, if the number of antennas of the terminal device is 2, the first capability is 2 antenna capability, and thus the first capability is lower than the second capability. The first capability may be considered to be configured by the first network device to adapt to the content of the first field, or to adapt to the received over-temperature related side information of the first field. The second capability may be the maximum capability supported by the terminal device, for example, the maximum capability reported to the network by the terminal device through the UE capability information message when accessing the network, or the second capability may be any capability lower than the maximum capability supported by the terminal device and higher than the first capability. After the terminal device communicates using the reduced air interface configuration, the power consumption is reduced, and the temperature of the terminal device is also reduced, thereby solving the overheating problem.

When the terminal device needs to be switched 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, and then the second network device cannot naturally know that the terminal device has adjusted the capability according to the first field. Therefore, the terminal device can readjust the capability of the terminal device to the second capability, so that the second network device can schedule the terminal device according to the second capability, and the probability of scheduling error caused by inconsistency between the capability of the terminal device understood by the second network device and the capability actually applied by the terminal device is reduced. For example, the maximum number of uplink MIMO layers that can be supported by each serving cell on each frequency band supported by the terminal device corresponding to the first capability is 2, and the maximum number of uplink MIMO layers that can be supported by each serving cell on each frequency band supported by the terminal device corresponding to the second capability is 4, then the terminal device may 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 this embodiment of the application, the configuration mode applied by the second network device is a relay-oriented configuration mode, or an iterative configuration mode, that is, a subsequent configuration needs to be performed based on a previous configuration, for example, the second configuration information is determined based on the third configuration information of the first network device, that is, the second configuration information is not configured in a full-configuration mode. In practical application, the second network device may also adopt a full configuration (full configuration) mode, where the full configuration mode is a mode in which all fields to be configured to the terminal device are reconfigured. For example, if the second network device adopts a full configuration mode, after receiving 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, the second network device may clean (e.g., discard) all the parameters (or all the fields) configured for the terminal device by the first network device, and may need to reconfigure all the fields configured for the terminal device. The method can also ensure that the terminal equipment and the second network equipment have consistent understanding on the configuration information, so that the terminal equipment can normally communicate under the second network equipment. However, in this way, since the second configuration information needs to be completely reconfigured, the amount of information included in the second configuration information may be large, and thus the transmission overhead may be large. The embodiment of the present application does not limit the configuration mode adopted by the second network device, but if the second network device adopts a full configuration mode, it is not necessary for the terminal device to execute a behavior of releasing the field that needs to be inherited.

Therefore, as an optional implementation, the second network device may send the configuration indication information to the first network device, and the first network device may receive the configuration indication information from the second network device. The configuration indication information may indicate that the second network device configures the terminal device in a full configuration mode, or indicate that the second network device does not configure the terminal device in a full configuration mode. For example, the configuration indication information may be sent to the first network device before cell handover, for example, the second network device may send the configuration indication information to the first network device before the first network device sends a handover preparation information message to the network device (as shown in S41 in the flow of fig. 4), or the second network device may send the configuration indication information to the first network device before sending the second configuration information to the terminal device, or the second network device may send the configuration indication information together with the second configuration information. After receiving the configuration indication information, the first network device may send the configuration indication information to the terminal device, so that the terminal device can receive the configuration indication information. For example, the first network device may send the configuration indication information to the terminal device included in an RRC reconfiguration message (S44 in the flow shown in fig. 4). If the configuration indication information indicates that the second network device does not configure the terminal device in the full configuration mode, the technical scheme provided by the embodiment of the application can be continuously executed; and if the configuration indication information indicates that the second network device configures the terminal device in a full configuration mode, the technical solution provided by the embodiment of the present application may not be necessarily executed. For example, if the configuration indication information indicates that the second network device configures the terminal device in a full configuration manner, after receiving the second configuration information, the terminal device may apply all or part of the configurations included in the second configuration information, and for the configuration information (e.g., the first configuration information) obtained previously from the first network device, the terminal device may discard the configuration information.

In addition, the embodiment of the present application may further continue to perform the cell handover procedure, for example, if the first network device sends the second configuration information to the terminal device through the handover command, the terminal device may then continue to perform steps such as S45 in the flow shown in fig. 4.

In this embodiment, 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 may release the configuration corresponding to the first field included in the first configuration information, that is, the terminal device does not apply the configuration corresponding to the first field received before. The second network device does not send the first field to the terminal device, possibly because the second network device cannot recognize the first field, the terminal device releases the configuration corresponding to the first field, so that the fields applied by the terminal device and the second network device are kept consistent, and the terminal device can normally communicate 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 the method. In the following description, the method is applied to the network architecture shown in fig. 3 as an example.

S61, the second network device sends the 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 a communication version of the second network device, e.g., the communication version of the second network device is the second version.

For example, S61 may be performed before the cell handover is performed. For example, before the first network device sends the handover preparation information message to the second network device (S41 in the flow shown in fig. 4), the second network device may send the 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 a communication version of the first network device. For example, the first version is v1540 and the second version is v1520, or the first version is v1540 and 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 that the configuration corresponding to the first field is released. 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 requirement code corresponding to the first field is a need M. For more explanation of the first field, reference may be made to the description relating to the embodiment shown in fig. 5.

S63 may also occur before a cell handover, for example, before the first network device sends a handover preparation information message to the second network device (S41 in the flow shown in fig. 4), the first network device sends the first information to the terminal device.

A network device cannot identify fields corresponding to other communication versions that are higher than the communication version of the network device. Before cell switching, the terminal device operates under the first network device, and the first network device may send 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 may obtain configuration information 2 according to the configuration information 1 and perform configuration according to the configuration information 2, so that normal communication with the first network device may be performed. As for the process in which the terminal device obtains the configuration information 2 from the configuration information 1, reference may be made to the related description of the embodiment shown in fig. 5 (in which the name of "first configuration information" in the related description of the embodiment shown in fig. 5 may be replaced with "configuration information 2" here, and the name of "third configuration information" in the related description of the embodiment shown in fig. 5 may be replaced with "configuration information 1" here).

In the cell handover process, the first network device may also send configuration information 1 to the second network device, and the second network device may determine, according to the configuration information 1, the configuration of the second network device to the terminal device, which is referred to as configuration information 3, for example. However, the communication version of the first network device is higher than that of the second network device, and therefore, the second network device cannot recognize the field corresponding to the first version and the fields corresponding to the other versions between the first version and the second version included in the configuration information 1. For unrecognized fields, the configuration information 3 determined by the second network device does not include these fields. And there may be fields (e.g. the first field) that need to be inherited from these fields, and since the configuration information 3 from the second network device does not include such fields, the terminal device will continue to apply the configuration corresponding to such fields included in the configuration information (e.g. the configuration information 2) from the first network device. The configuration corresponding to such field is not supported by the second network device, and if the terminal device continues to configure the configuration corresponding to such field included in the configuration information 2, a problem may occur in communication of the terminal device under the second network device, for example, the terminal device may not 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, the first network device may instruct, by sending the first information to the terminal device, the terminal device to release all or part of the configuration corresponding to the field that needs to be inherited (or release all or part of the content included in the field that needs to be inherited). All or part of the fields to be inherited may be 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 to be inherited included in the configuration information 2. For example, the first field is one of the fields that need to be inherited in whole or in part, for example, the first field includes over-temperature configuration information, and the over-temperature configuration information may include the second indication information, or include the timing length of the prohibit timer, or include the second indication information and the timing length of the prohibit timer. Wherein the second indication information is used for indicating whether the overheating related auxiliary information can be sent to the network device, and the terminal device cannot send the overheating related auxiliary information to the network device during the running time of the prohibition timer. For the introduction of the overheating configuration information and the auxiliary information related to overheating, reference is made to the embodiment shown in fig. 5. The "first instruction information" in the embodiment shown in fig. 5 corresponds to the "second instruction information" herein.

As an optional implementation manner, all or part of the fields that need to be inherited may include a field corresponding to the first version, a field corresponding to another version between the first version and the second version, a field corresponding to the second version, and a field corresponding to another version lower than the second version. For example, if the second version is v1520 and the first version is v1540, the first indication information may instruct the terminal device to release the field requiring inheritance corresponding to v1540, the field requiring inheritance corresponding to v1530, the field requiring inheritance corresponding to v1520, and the field requiring inheritance corresponding to v 1510. That is, in this manner, the first network device does not determine the version corresponding to the field, and does not need to determine the specific version of the second network device, as long as the second version is lower than the first version, as long as the field that needs to be inherited and included in the configuration information 2 is included, the first network device may instruct the terminal device to release the field regardless of whether the second network device supports the field. In this way, the terminal device does not inherit the fields, so that the understanding of the fields by the terminal device and the second network device is consistent, and the terminal device can normally communicate under the second network device.

As another alternative, all or part of the fields that need to be inherited may include a field corresponding to the first version, a field corresponding to another version between the first version and the second version, but no field corresponding to the second version, and no field corresponding to another version lower than the second version. Because the communication version of the second network device is the second version, whether the field corresponding to the second version or the field corresponding to the other version lower than the second version is supported by the second network device, if the field is included in the configuration information and sent to the second network device by the first network device, the second network device can identify and can perform further configuration according to the field. Therefore, in this manner, the first network device needs to determine a specific version of the second network device and also needs to determine a version corresponding to the field, and the first network device merely instructs the terminal device to release the field corresponding to the first version and release the fields corresponding to the other versions between the first version and the second version, or the first network device instructs to release the field higher than the second version but does not need to release the field corresponding to the second version and does not need to release the fields corresponding to the other versions lower than the second version. Therefore, the understanding of the second network device and the terminal device to the configuration information can be kept consistent, and the fields needing to be released by the terminal device are fewer, so that the workload of the terminal device can be reduced. And the second network device can also carry out further configuration on the unreleased fields which can be identified by the second network device, thereby being beneficial to reducing the workload of the second network device.

Wherein, the first information can have different implementation manners.

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, and the content of each field in all or part of the fields that need to be inherited in the configuration information 2 is set as the first content, so that the obtained configuration information may be the first information. The first content may indicate that the corresponding field is released. For example, if the configuration information 2 includes a first field, the first information also includes the first field, and the content of the first field is first content, and the first content is used to indicate to release 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 set to "release" for the first content, that is, the content of the first field. Then, after receiving the first information, the terminal device releases the content of the first field included in the configuration information 2 stored at the terminal device side according to the first content included in the first field, so that the configuration corresponding to the first field included in the configuration information 2 is not continuously applied.

In this embodiment, it is equivalent to that the first network device retransmits the configuration information to the terminal device, where the configuration information is used to indicate that all or part of the fields included in the release configuration information 2 need to be inherited. The indication mode is more specific 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 that a configuration corresponding to one or more fields, for example, one of the one or more fields, is released. For example, the first indication information occupies one bit, and if the value of the one bit is "0", it indicates that the configuration corresponding to the one or more fields is released, and if the value of the one field is "1", it indicates that the configuration corresponding to the one or more fields is not released. Or, the first indication information may occupy one or more bits, and if the first network device sends the first indication information to the terminal device, it indicates to release the configuration corresponding to the one or more fields, and if the first network device does not send the first indication information to the terminal device, it indicates not to release the configuration corresponding to the one or more fields. The one or more fields are all fields that need to be inherited, and the one or more fields are all or part of fields that need to be inherited and included in the configuration information 2, that is, the first indication information is used to indicate that all or part of fields that need to be inherited and included in the configuration information 2 are released. After the terminal device receives the first indication information, the content of all or part of the fields that need to be inherited included in the configuration information 2 stored at the terminal device side can be released, so that the configuration corresponding to the fields included in the configuration information 2 is not continuously applied. For example, the field released by the terminal device includes a first field.

In this embodiment, the first network device does not need to retransmit the configuration information to the terminal device, but only needs to transmit the first indication information to the terminal device, so as to be able to indicate to release the corresponding field. Compared with the configuration information, the information amount of the first indication information is small, and transmission overhead is saved.

S64, the first network device sends the first configuration information to the second network device, and accordingly, the second network device receives the first configuration information from the first network device. For example, the first network device may send the first configuration information to the second network device included in a handover preparation information message (e.g., S41 in the flow illustrated in fig. 4).

For example, the first network device may obtain the first configuration information according to configuration information 2. For example, the first network device deletes all or part of the fields to be inherited from the configuration information 2, and the configuration information obtained thereby may be the first configuration information. These fields which the first network device deletes from the configuration information 2, i.e. the fields which the first network device indicates to the terminal device that release is required. As described in S63, the field deleted by the first network device may include fields corresponding to all versions, where all versions 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, and in this case, the first field may correspond to any one of all versions. Alternatively, the field deleted by the first network device includes only the field corresponding to the first version and the fields corresponding to the other versions between the first version and the second version, but does not include the field corresponding to the second version and does not include the fields corresponding to the 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, and in this case, the first field may correspond to the second version or to another version between the second version and the first version.

After the second network device obtains the first configuration information, the terminal device may be configured according to the first configuration information. Since the first configuration information does not include the field which is unrecognizable by the second network device and needs to be inherited, the second network device can normally configure the terminal device. For example, the second network device may obtain the second configuration information, which may be obtained from the first configuration information, for example. For a field that needs to be inherited and 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 accordingly, the terminal device receives the second configuration information from the second network device.

After the second network device obtains the second configuration information, the second configuration information can be sent to the terminal device, so that the terminal device can perform configuration according to the second configuration information, and can perform normal communication under the second network device after being switched 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 transmit the second configuration information to the first network device in a handover control message as described in S43 of the flow shown in fig. 4, and the first network device may transmit the second configuration information to the terminal device in an RRC reconfiguration message as described in S44 of the flow shown in fig. 4.

S66, the first network device sends a handover command to the terminal device, and accordingly, the terminal device receives the handover command from the first network device. The handover command may be, for example, an RRC reconfiguration message described in S44 in the flow illustrated in fig. 4, and may be used to instruct the terminal device to handover to the second network device. After performing S66, the steps of S45 and the like in the flow shown in fig. 4 may be continuously performed, i.e., the cell handover procedure may be continuously performed.

Wherein, if the first network device can transmit the second configuration information to the terminal device in the RRC reconfiguration message described as S44 in the flow shown in fig. 4, S66 may be actually considered as being included in S65.

In addition, in this embodiment of the application, the configuration mode applied by the second network device is a relay-oriented configuration mode, or an iterative configuration mode, that is, a subsequent configuration needs to be performed based on a previous configuration, for example, the second configuration information is determined based on the first configuration information of the first network device, that is, the second configuration information is not configured in a full-configuration mode. In practical application, the second network device may also adopt a full configuration mode, where the full configuration mode is a mode in which all fields to be configured to the terminal device are all reconfigured. With regard to the manner of full configuration, reference may be made to the related description of the embodiment shown in fig. 5. The embodiment of the present application does not limit the configuration mode adopted by the second network device, but if the second network device adopts a full configuration mode, it is not necessary for the first network device to instruct the terminal device to release the field that needs to be inherited.

Therefore, as an optional implementation, the second network device may send the configuration indication information to the first network device, and the first network device may receive the configuration indication information from the second network device. The configuration indication information may indicate that the second network device configures the terminal device in a full configuration mode, or indicate that the second network device does not configure the terminal device in a full configuration mode. As to the transmission manner of the configuration indication information, reference may be made to the related description of the embodiment shown in fig. 5. After the first network device receives the configuration indication information, if the configuration indication information indicates that the second network device does not configure the terminal device in the full configuration mode, the technical solution provided by the embodiment of the present application may be continuously executed, for example, the first network device may send the first information to the terminal device; however, if the configuration indication information indicates that the second network device configures the terminal device in the full configuration mode, it may not be necessary to execute the technical solution provided in the embodiment of the present application, for example, the first network device does not need to send the first information to the terminal device.
