Description

Technical Field

[0001] The present application relates to the field of wireless technology, and in particular to a configuration application method, apparatus, terminal and network equipment. Background Art

[0002] Conditional PSCell Addition / Change (CPAC) is to pre-configure multiple candidate PSCell configuration information for the user equipment (UE) or user terminal, and configure corresponding execution conditions for each candidate PSCell. When the UE receives the CPAC configuration information, the UE starts to evaluate the CPAC execution conditions. When the UE evaluates that the execution conditions are met, the UE will execute the PSCell change to access the candidate target PSCell that meets the execution conditions.

[0003] For subsequent CPAC, the UE uses complete configuration to replace the current Master Cell Group (MCG) configuration and / or Secondary Cell Group (SCG) configuration when applying the configuration, but this will cause an interruption in the MCG underlying layer and a mismatch in the MCG configuration on the UE and MN sides, that is, the data transmission on the MCG side is affected by the PSCell addition / change on the SCG side.

[0214] The following first introduces the contents involved in the solution provided in the embodiment of the present application. At present, for the first execution standard of CPAC, multiple candidate PSCell configuration information is pre-configured for the UE, and corresponding execution conditions are configured for each candidate PSCell. When the UE receives the CPAC configuration information, the UE starts to evaluate the CPAC execution conditions. When the UE evaluates that the execution conditions are met, the UE will execute the PSCell change to access the candidate target PSCell that meets the execution conditions. After the UE successfully executes the PSCell change to access the candidate target cell, the UE will release the stored CPAC configuration information.

[0215] For the inter-SN CPAC scenario, when the UE performs CPAC, it will send a reconfiguration completion message on the master node MN to notify the network side, where the reconfiguration completion message carries the indication information of the applied CPAC configuration and the reconfiguration completion message sent to the SN side. After receiving the reconfiguration completion message sent by the UE, the MN side can determine the CPAC configuration applied by the UE based on the indication information, and forward the reconfiguration completion message sent to the SN side to the SN.

[0216] For the second implementation standard of CPAC, considering the first implementation standard, the CPAC configuration will be deleted after each PSCell change is executed. If the network wants the UE to continue to execute CPAC, the network side needs to reconfigure and reinitialize the CPAC process, which will increase the air interface signaling overhead and latency. Therefore, the second implementation standard supports continuous subsequent CPAC, that is, after the UE successfully executes CPAC, the UE does not release the CPAC configuration, the UE continues to evaluate the CPAC execution conditions, and continues the subsequent CPAC.

[0217] In the first implementation standard, the configuration information of the candidate cell configured by the network side for the UE is an incremental delta configuration generated based on the configuration currently applied by the UE, wherein the configuration information of the candidate cell includes the configuration information of the MCG and SCG. In the second implementation standard, in order to support the subsequent CPAC process, since the serving cell can be any other candidate cell when the UE applies any candidate cell configuration information, the delta configuration generated based on the configuration information currently applied by the UE will no longer be suitable as the candidate cell configuration information. For this reason, the second implementation standard will support the generation of candidate configuration information based on the reference configuration information, that is, the configuration information applied by the UE when executing subsequent CPAC is the complete configuration information generated based on the reference configuration information and the candidate configuration information, and the complete configuration information will replace the current configuration information based on certain principles.

[0218] According to the above, in the second implementation standard, for subsequent CPAC, after the UE successfully executes CPAC, the UE does not release the CPAC configuration, but continues to evaluate the CPAC execution conditions and continues the subsequent CPAC. Subsequent CPAC is configured in the manner of reference configuration + delta configuration = complete configuration. When applying the configuration, the UE replaces the current MCG configuration and / or SCG configuration with the complete configuration, which will cause an interruption in the MCG underlying layer and a mismatch between the MCG configurations on the UE and MN sides, i.e., the data transmission on the MCG side is affected by the addition / change of the PSCell on the SCG side.

[0219] To solve the above problems, an embodiment of the present application provides a configuration application method. For the addition / change of continuous conditional cells, when applying the candidate target cell configuration, by executing one or more of not updating the MCG underlying configuration, sending a first indication information indicating the first target configuration to the network device, and applying the restricted bearer network configuration, it is ensured that the applied configuration will not affect the data transmission on the MCG side.

[0220] Figure 1 This is a flow chart of a configuration application method according to one embodiment of the present application; in this embodiment, the configuration application method is executed by a terminal, and the method includes:

[0221] S110, the terminal performs continuous conditional cell addition / change, including one or more of the following:

[0222] Application restriction bearer's first target configuration;

[0223] The underlying configuration of the master cell group MCG is not updated;

[0224] Sending first indication information to the network device, where the first indication information is used to indicate a first target configuration;

[0225] The sending of the first indication information to the network device includes one or more of the following:

[0226] Before performing continuous conditional cell addition / change, or during the continuous conditional cell addition / change process, sending the first indication information to the network device through the current MCG configuration;

[0227] After performing continuous conditional cell addition / change, the first indication information is sent to the network device through the changed secondary cell group SCG.

[0228] By adopting the configuration application method described in the embodiment of the present application, for continuous conditional cell addition / change, when applying the candidate target cell configuration, by executing not to update the MCG underlying configuration, the MCG underlying configuration is avoided to avoid the MCG underlying interruption caused by the change of the MCG underlying configuration after the continuous conditional cell addition / change is executed; by sending the first indication information to the network device, the network device obtains the new MCG configuration applied on the UE side, so as to avoid the mismatch of the MCG configuration applied on the UE side and the MN side, which causes the MCG underlying interruption, so as to ensure that the MCG configuration applied on the UE and MN sides are aligned, so as to avoid the inability to send and receive data normally between the UE and the network side, and even the MN cannot receive the reconfiguration completion message sent by the UE side; by applying the first target configuration of the restricted bearer, the terminal retains and applies (maintains the application) the current MCG configuration or MCG underlying configuration when applying the complete configuration, and does not perform the release / clearance operation of the MCG side configuration or the MCG underlying configuration, so as to ensure that the UE can continue to interact with the MCG for underlying signaling / data, and avoid the MCG underlying interruption.

[0229] In the embodiment of the present application, optionally, the continuous conditional cell addition / change can be a continuous secondary cell group primary cell addition / change (subsequent CPAC), or a continuous primary cell group primary cell change. The execution of the continuous conditional cell addition / change includes: using the reference configuration and the candidate cell configuration to generate a complete configuration, that is, generating a complete configuration of the candidate target cell.

[0230] Optionally, the network device may be, but is not limited to, only a master node MN.

[0231] In some of the embodiments, the first indication information sent by the terminal is used to indicate a first target configuration, where the indicated first target configuration may be a complete configuration of a candidate target cell generated by the UE based on a reference configuration and / or a candidate cell configuration, and the target cell is a target cell accessed by the UE during a cell addition / change process.

[0232] In an embodiment of the present application, the UE sends a first indication message to a network device, where the first indication message is used to indicate a first target configuration. Optionally, the first indication message instructs the UE side to add / change the selected access target candidate cell or target candidate cell configuration or the first target configuration or conditional reconfiguration identifier in this cell. The MN determines the MCG configuration and / or MCG underlying configuration selected by the UE for application based on the first indication message.

[0233] It should be noted that in the embodiment of the present application, before executing the continuous conditional cell addition / change, it can also be described as before applying the first target configuration; during the process of executing the continuous conditional cell addition / change, it can also be described as during the process of applying the first target configuration; after executing the continuous conditional cell addition / change, it can also be described as after applying the first target configuration.

[0234] In one embodiment of the present application, when the terminal performs continuous conditional cell addition / change, the underlying configuration of the main cell group MCG is not updated.

[0235] Among them, not updating the MCG underlying configuration mentioned in the embodiments of the present application can also be described as not updating the MCG underlying configuration of the current application.

[0236] Optionally, the MCG bottom layer configuration includes one or more of the following configurations:

[0237] Physical layer configuration;

[0238] Media Access Control (MAC) layer configuration;

[0239] Radio Link Control (RLC) layer configuration;

[0240] Packet Data Convergence Protocol (PDCP) layer configuration.

[0241] In some of the embodiments, the not updating the underlying configuration of the master cell group MCG includes one or more of the following:

[0242] Do not release or clear the MCG underlying configuration;

[0243] The MCG underlying configuration is not replaced;

[0244] Apply the target MCG underlying configuration based on the incremental delta configuration of the current MCG;

[0245] Applying a first MCG configuration based on an incremental delta configuration of the current MCG;

[0246] Maintain the current MCG underlying configuration of the application;

[0247] Maintains the application's current MCG configuration.

[0248] It should be noted that in the embodiment of the present application, the current MCG underlying configuration is also the MCG underlying configuration of the current application, and the current MCG configuration is also the MCG configuration of the current application.

[0249] The following are explanations of various ways of not updating the underlying configuration of the master cell group MCG:

[0250] Not releasing or clearing the MCG underlying configuration means that when the UE is performing cell addition / change and applying the first target configuration, the UE does not release or clear the MCG side underlying configuration.

[0251] Not replacing the MCG underlying configuration means that when the UE is performing cell addition / change, when applying the first target configuration, the MCG side underlying configuration in the first target configuration will not be used to replace the currently applied MCG underlying configuration.

[0252] Applying the target MCG underlying configuration based on the incremental delta configuration of the current MCG means that when the UE is performing cell addition / change, when applying the first target configuration, the MCG underlying configuration applied in the first target configuration is a complete MCG underlying configuration generated by the UE based on the currently applied MCG underlying configuration and the candidate cell configuration. The network should ensure that the complete underlying MCG configuration generated by the UE application does not affect the underlying data transmission of the current MCG, or the network ensures that the generated complete MCG underlying configuration is only the MCG underlying configuration related to PSCell addition / change.

[0253] Applying the first MCG configuration based on the incremental delta configuration of the current MCG means that when the UE is performing cell addition / change, when applying the first target configuration, the MCG configuration in the applied first target configuration is a complete MCG configuration generated by the UE based on the currently applied MCG configuration and the candidate cell configuration. The network should ensure that the complete MCG configuration generated by the UE application does not affect the underlying data transmission of the current MCG, or the network ensures that the generated complete MCG configuration is only the MCG configuration related to PSCelladdition / change.

[0254] It should be noted that the first MCG configuration is the MCG configuration generated based on the current MCG configuration and the candidate cell configuration.

[0255] Maintaining the application of the current MCG underlying configuration can be interpreted as that when the UE is performing the cell addition / change process and applying the first target configuration, the UE continues to apply the current MCG underlying configuration, that is, during the cell addition / change process or after the UE performs the cell addition / change process, the MCG underlying configuration is still the currently applied MCG underlying configuration.

[0256] Maintaining the current MCG configuration can be interpreted as the UE continuing to apply the current MCG configuration when applying the first target configuration during the cell addition / change process, that is, the MCG configuration of the UE is still the currently applied MCG configuration during or after the cell addition / change process. The not updating the primary cell group MCG underlying configuration includes:

[0257] In some of the embodiments, when the first condition is met, the MCG underlying configuration is not updated;

[0258] The first condition includes one or more of the following:

[0259] The first target configuration includes MCG bottom layer configuration;

[0260] The first target configuration includes an MCG underlying configuration, and the MCG underlying configuration in the first target configuration is the same as the current MCG underlying configuration;

[0261] The first target configuration includes an MCG underlying configuration, and the MCG underlying configuration in the first target configuration is generated based on the current MCG underlying configuration;

[0262] The first target configuration includes an MCG configuration, and the MCG configuration in the first target configuration is generated based on the current MCG configuration;

[0263] The first target configuration does not include the MCG underlying configuration;

[0264] The first target configuration does not include MCG configuration.

[0265] In some of the embodiments, the first target configuration includes the MCG underlying configuration. In this embodiment, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration (first target configuration) includes the MCG underlying configuration, that is, the reference configuration and / or the candidate cell configuration includes the MCG underlying configuration.

[0266] In this embodiment, the terminal performs continuous conditional cell addition / change without updating the underlying configuration of the master cell group MCG, which may include one or more of the following implementations:

[0267] In the first implementation mode, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, if the complete configuration includes the MCG underlying configuration, the execution of the MCG underlying configuration is skipped when the complete configuration is applied, that is, the release operation, the clearing operation and the process of replacing the new configuration are not performed for the MCG underlying configuration. The network ensures that when the UE applies the continuous conditional cell addition / change configuration, the MN side can receive the reconfiguration completion message sent by the UE. The replacement of the new configuration is not performed here, that is, the MCG underlying configuration is not replaced, specifically, the MCG underlying configuration in the complete configuration (first target configuration) is not used to replace the current MCG underlying configuration; for example, the MAC layer and physical layer configuration of the MCG are configured in the reference configuration and the candidate cell configuration. When the UE performs continuous conditional cell addition / change and applies the complete configuration, when the UE executes the MAC layer and physical layer configuration, the execution of the MAC layer and physical layer configuration will be skipped, that is, the release / clearing operation is not performed due to the new MAC layer and physical layer configuration, and the new MAC layer and physical layer configuration is not used to replace the old MAC layer and physical layer configuration process, ensuring that the UE can continue to interact with the MCG for underlying signaling / data.

[0268] In the second implementation mode, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration (first target configuration) includes the MCG underlying configuration, and the MCG underlying configuration in the complete configuration is the same as the current MCG underlying configuration. When the UE performs continuous conditional cell addition / change and applies the complete configuration, if it is found that the configurations are the same, the configuration will not be applied / updated, that is, the release / clear operation will not be performed on the underlying configuration of the MCG, and the process of replacing the new configuration will not be performed. The network ensures that when the UE applies the configuration of continuous conditional cell addition / change, the MN side can receive the reconfiguration completion message sent by the UE. Not replacing the new configuration here means not using the new configuration to replace the old configuration.

[0269] For example, the network ensures that when configuring the reference configuration and the candidate cell configuration, the MCG underlying configuration in the complete configuration finally generated by the reference configuration and the candidate cell configuration is the same as the current MCG underlying configuration. If the physical layer configuration is the same, when the UE performs PSCell addition / PSCell change and applies the complete configuration, it determines that the MCG physical layer configuration in the complete configuration of the candidate target cell is the same as the current MCG physical layer configuration. The UE does not update the configuration, that is, it does not perform a release / clear operation due to the new physical layer configuration, and does not use the new physical layer configuration to replace the old physical layer configuration. The UE can continue to interact with the MCG for underlying signaling / data.

[0270] In the third implementation mode, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration (first target configuration) includes the MCG underlying configuration. When the UE applies the MCG side configuration, it applies the target MCG underlying configuration based on the incremental delta configuration of the current MCG; when applying the SCG side configuration, it applies it according to the replace principle based on the reference configuration and the candidate cell configuration. Specifically, the target MCG underlying configuration is the MCG underlying configuration obtained by adding the delta configuration to the current MCG underlying configuration. Compared with determining the MCG underlying configuration by using the reference configuration and the candidate cell configuration, this implementation mode can ensure that the determined MCG underlying configuration is not updated.

[0271] In this implementation, when configuring the reference configuration and / or the candidate cell configuration, the network device ensures that the MCG underlying configuration in the determined complete configuration remains unchanged for different target cells. In this way, the UE can continue to perform underlying signaling / data interaction with the MCG.

[0272] In the fourth implementation mode, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration (first target configuration) includes the MCG underlying configuration, but the MCG underlying configuration of the first target configuration corresponding to different target cells configured by the network device remains unchanged, thereby ensuring that the UE does not change the MCG underlying configuration when applying different candidate target cells. In this implementation mode, when the UE performs continuous conditional cell addition / change and applies the complete configuration, it is allowed to perform a clear / release operation. This method is based on the network configuration to ensure that the UE will not affect the MCG underlying configuration during the continuous cell addition / change process, and ensure that data transmission can be performed normally on the MCG side.

[0273] In this implementation, optionally, when applying the MCG side configuration, the UE may apply the target MCG underlying configuration based on the incremental delta configuration of the current MCG.

[0274] In some of the embodiments, the first target configuration corresponding to the accessed target cell does not include the MCG underlying configuration or the MCG configuration. In this embodiment, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration does not include the MCG underlying configuration or the MCG configuration, that is, the reference configuration and / or the candidate cell configuration does not include the MCG underlying configuration or the MCG configuration.

[0275] Implementation method five, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration does not include the MCG underlying configuration, that is, the reference configuration and the candidate cell configuration do not include the MCG underlying configuration. When applying the complete configuration, the UE retains and applies (maintains the application) the current MCG underlying configuration, and applies the configuration information included in the complete configuration according to the specified principles, such as releasing / clearing part of the configuration information and applying the corresponding configuration information in the complete configuration, to ensure that the UE can continue to interact with the MCG for underlying signaling / data.

[0276] Implementation method six, when the terminal generates a complete configuration based on the reference configuration and the candidate cell configuration and determines the configuration of the target cell, the complete configuration does not include the MCG configuration, that is, the reference configuration and the candidate cell configuration do not include the MCG configuration. In this implementation method, when applying the complete configuration, the UE retains and applies (maintains the application) the MCG configuration of the current MCG, and does not perform the release / clear operation of the MCG side configuration, thereby ensuring that the UE can continue to perform underlying signaling / data interaction with the MCG.

[0277] In the embodiment of the present application, optionally, the method further includes:

[0278] Receive a second target configuration sent by the network device, where the second target configuration includes a network configuration that causes the terminal not to update the MCG underlying configuration.

[0279] Optionally, the second target configuration includes a reference configuration and / or a candidate cell configuration sent by the network device for generating the first target configuration of the target cell.

[0280] With this embodiment, the terminal generates the first target configuration according to the second target configuration sent by the network device.

[0281] In some other embodiments of the present application, the terminal performs continuous conditional cell addition / change and applies a first target configuration of a restricted bearer. Optionally, the first target configuration of the restricted bearer includes one or more of the following:

[0282] Applying the first target configuration, not performing any operation of adding, modifying, and releasing the MCG bearer for the master node MN, and not performing any operation of adding, modifying, and releasing the MCG RLC bearer;

[0283] Applying the first target configuration, neither the adding operation nor the releasing operation of the SN-terminated SCG bearer is performed, and neither the adding operation, the modifying operation nor the releasing operation of the MN-terminated MCG bearer is performed.

[0284] By adopting this embodiment, the network configures the network configuration of the restricted bearer for the terminal. When the terminal performs the addition / change of continuous conditional cells, the network configuration of the restricted bearer is applied, that is, restrictions are added to the network when performing the bearer configuration, and the operation mode of the executed bearer is restricted. For example, the present application only adds, modifies and / or releases the SN terminated SCG bearer by applying the network configuration of the restricted bearer, and does not perform the addition, modification and / or release of the MCG side configuration. Compared with no restriction on the bearer configuration, adding, modifying and / or releasing are performed on all types of bearers. By adopting this implementation mode, adding, modifying and / or releasing the MCG side configuration is not performed, which can ensure that the UE can continue to perform underlying signaling / data interaction with the MCG.

[0285] In some embodiments of the present application, none of the operations of adding, modifying and releasing the MCG bearer terminated by the master node MN is performed, and none of the operations of adding, modifying and releasing the MCG RLC bearer is performed. It can also be described as only allowing one or more of the operations of adding, modifying and releasing the bearer of the SN terminated SCG bearer type.

[0286] In some embodiments of the present application, none of the operations of adding and releasing the SN terminated SCG bearer is performed, and none of the operations of adding, modifying and releasing the MN terminated MCG bearer is performed. It can also be described as allowing only modification operations on bearers of the SN terminated SCG bearer type.

[0287] Optionally, the network configures a network configuration for the terminal to restrict the bearer, including one or more of the following:

[0288] Before performing continuous conditional cell addition / change, the network device configures the MN terminated MCG bearer and / or the SN terminated SCG bearer, and configures the terminal to perform one or more of the addition, modification and release operations on the bearer of the SN terminated SCG bearer type when performing continuous conditional cell addition / change (not limited to the addition, release and modification of the data radio bearer (Date Resource Bearer, DRB) / signal radio bearer (Signal Resource Bearer, SRB), the modification of the PDCP, and the addition, release and / or modification of the RLC bearer);

[0289] Before performing continuous conditional cell addition / change, the network device configures the MN terminated MCG bearer and / or the SN terminated SCG bearer, and configures the terminal to only allow modification of the SN terminated SCG bearer configuration; in this implementation, the terminal is only allowed to perform modification operations of the SN terminated SCG bearer type bearer;

[0290] Before performing continuous conditional cell addition / change, the network device configures the MN terminated MCG bearer and / or the SN terminated SCG bearer, and configures the terminal not to perform any of the addition, modification and release operations on the MN terminated MCG bearer, and not to perform any of the addition, modification and release operations on the MCG RLC bearer when performing continuous conditional cell addition / change;

[0291] Before performing continuous conditional cell addition / change, the network device configures the MN terminated MCG bearer and / or SN terminated SCG bearer, and configures the terminal not to allow the addition and release of the SN terminated SCG bearer configuration when performing continuous conditional cell addition / change, and not to allow the addition, modification and release of the MN terminated MCG bearer.

[0292] In the embodiment of the present application, the network device configures a third target configuration for the terminal, and the third target configuration includes a network configuration for limiting the bearer, so that the terminal applies a specific implementation of the first target configuration for limiting the bearer, and the examples are as follows:

[0293] 1) In the third target configuration configured by the network device, the MCG underlying configuration is not allowed to be configured in the complete configuration generated based on the reference configuration and the candidate cell configuration. Because the bearer configuration is restricted, the underlying configuration can remain unchanged. This also applies to the following. One or more of the following configurations can be configured in the complete configuration:

[0294] SN RRC Reconfiguration configuration;

[0295] SN terminated SCG bearer configuration;

[0296] The cell group configuration information (including physical layer configuration, MAC layer configuration and RLC layer configuration information, etc.) may not be included in the reference configuration and candidate cell configuration, that is, the cell group configuration information, etc. may not be configured.

[0297] 2) In the third target configuration configured by the network device, the MCG underlying configuration is allowed to be configured in the complete configuration generated based on the reference configuration and the candidate cell configuration, and the reference configuration and / or the candidate cell configuration allow the MCG underlying configuration to be configured. Before the UE performs continuous conditional cell addition / change, the MCG underlying configuration is skipped when applying the complete configuration, and only the SNRRCReconfiguration configuration, SN terminated SCG bearer configuration, etc. are applied;

[0298] 3) In the third target configuration configured by the network device, the MCG underlying configuration is allowed to be configured in the complete configuration generated based on the reference configuration and the candidate cell configuration. The reference configuration and / or the candidate cell configuration allows the MCG underlying configuration to be configured. The network ensures that the MCG underlying configuration in the complete configuration is the same as the current MCG underlying configuration. Before the UE performs continuous conditional cell addition / change, if it is found that the configuration is the same when applying the complete configuration, the configuration will not be applied / updated (e.g., the MCG cell group configuration in the complete configuration is the same as the currently used MCG cell group configuration, the UE does not apply the MCG cell group configuration in the complete configuration or the UE does not update the current MCG cell group configuration).

[0299] It should be noted that the above-mentioned specific implementation method of the first target configuration of terminal application restricted bearer based on the network configuration of restricted bearer of the network equipment is only for illustration and is not limited to this. The method described in this application does not update the various implementation methods of the underlying configuration of the main cell group MCG, and can be used in the specific implementation method of using the network configuration of restricted bearer to execute continuous conditional cell addition / change.

[0300] In some embodiments of the present application, the terminal performs continuous conditional cell addition / change and sends first indication information to a network device, where the first indication information is used to indicate a first target configuration.

[0301] In one implementation manner, optionally, sending the first indication information to the network device includes one or more of the following:

[0302] Before performing continuous conditional cell addition / change, or during the continuous conditional cell addition / change process, sending the first indication information to the network device through the current MCG configuration;

[0303] After performing continuous conditional cell addition / change, the first indication information is sent to the network device through the changed secondary cell group SCG.

[0304] By adopting this implementation mode, the terminal sends a first indication message to the network device to indicate the first target configuration, so that the network device can obtain the new MCG configuration applied on the UE side, avoiding the MCG underlying layer interruption, so as to ensure that the configuration applied by the terminal will not affect the data transmission on the MCG side.

[0305] In addition, by sending the first indication information to the network device through the terminal, the network device can determine the target MCG configuration on the network side according to the first indication information to ensure that the configuration of the terminal matches that of the network side, so as to avoid the problem that the UE and the network side cannot send and receive data normally, or even the MN cannot receive the reconfiguration completion message sent by the UE side.

[0306] In one embodiment, before executing the continuous conditional cell addition / change, or during the continuous conditional cell addition / change process, the first indication information is sent to the network device through the current MCG configuration. In this embodiment, the terminal adopts the currently applied MCG configuration and directly sends the first indication information to the network device (optionally the master node MN) to notify the MN of the first target configuration to be applied.

[0307] Optionally, the first indication information includes conditional reconfiguration identification information selected for performing continuous conditional cell addition / change, and the first target configuration is a target cell configuration corresponding to the conditional reconfiguration identification information.

[0308] With this implementation, the terminal indicates the target cell configuration corresponding to the conditional reconfiguration identification information by sending the conditional reconfiguration identification information.

[0309] In some of the embodiments, optionally, the terminal may send the first indication information to the MN via SRB1.

[0310] Optionally, the first indication information is sent in one or more of the following ways:

[0311] Radio Resource Control (RRC) reconfiguration complete message;

[0312] UE assistance information message;

[0313] Media Access Control (MAC) control element (CE).

[0314] In this implementation manner, optionally, the first indication information may be carried in any uplink message, such as an RRC reconfiguration completion RRCReconfigurationComplete message or a UAI (UE assistance information) message; or may be sent via a MAC CE.

[0315] Specifically, the terminal indicates to the MN the new MCG configuration (first target configuration) to be applied through the first indication information. Optionally, the first indication message includes the selected conditional reconfiguration identification information, etc. When the MN receives the conditional reconfiguration identification information, the MN can determine the MCG configuration to be used by the UE according to the conditional reconfiguration identification information, and determine the target MCG configuration applied by the network side according to the first indication information. Optionally, the network side determines that the target MCG configuration to be applied is the same MCG configuration as the UE side.

[0316] Optionally, when the first indication information is included in an RRC message, and the RRC message is an RRCReconfigurationComplete message, the message may be a response message to RRCReconfiguration for performing PSCell addition / PSCell change, and may optionally also include an RRC reconfiguration complete message sent to the SN, without limitation.

[0317] In some embodiments of the present application, when the first indication information is sent to the network device through the current MCG configuration, the method further includes one or more of the following:

[0318] After receiving the first feedback information sent by the network device, performing continuous conditional cell addition / change and applying the first target configuration;

[0319] During the process of sending the first indication information, or after sending the first indication information, performing continuous conditional cell addition / change and applying the first target configuration;

[0320] Receiving scheduling information sent by the network device using a target MCG configuration; wherein the target MCG configuration is determined according to the first indication information; optionally, the target MCG configuration is an MCG configuration in the first target configuration;

[0321] After performing continuous conditional cell addition / change, sending uplink information to the network device using the first target configuration;

[0322] After sending uplink information to the network device using the first target configuration, receiving downlink information sent by the network device in response to the uplink information;

[0323] Receive second feedback information sent by the network device to the terminal using the target MCG configuration after applying the target MCG configuration.

[0324] Using the configuration application method described in this embodiment, before executing the addition / change of continuous conditional cells, or during the process of adding / changing continuous conditional cells, after sending the first indication information to the network device through the current MCG configuration, in one implementation mode, optionally, the first target configuration can be applied only after receiving the feedback information sent by the network device based on the first indication information; in another implementation mode, optionally, the terminal can directly apply the first target configuration without waiting for the feedback of the network device after sending the first indication information; in another implementation mode, optionally, the terminal can directly apply the first target configuration without waiting for the feedback of the network device after sending the first indication information, and use the updated first target configuration to send uplink information to the network device; in another implementation mode, optionally, the terminal can directly apply the first target configuration without waiting for the feedback of the network device after sending the first indication information, and receive the feedback information of configuration completion sent by the network device. In another implementation mode, optionally, the terminal can directly receive the scheduling sent by the network using the target MCG configuration without waiting for the feedback of the network device after sending the first indication information.

[0325] It should be noted that the above-mentioned implementation modes are merely examples of the configuration application method described in the embodiments of the present application, and are not specifically limited to this.

[0326] In some other embodiments of the present application, after executing continuous conditional cell addition / change, the terminal sends the first indication information to the network device through the changed secondary cell group SCG.

[0327] Using this implementation mode, when the terminal performs continuous conditional cell addition / change, after applying the first target configuration of the accessed target cell, the secondary cell group SCG updated by the accessed target cell sends a first indication message to the MN, and notifies the MN of the first target configuration applied to the accessed target cell through the first indication message.

[0328] Optionally, the first indication information is sent in one or more of the following ways:

[0329] Through SRB3 transparent transmission;

[0330] splitSRB1;

[0333] The UE sends an RRC message to the SN, where the RRC message includes the first indication information. The RRC message may be directly sent to the SN, and the SN notifies the MN through an interface.

[0334] The UE carries the first indication information in an SN message, such as ULInformationTransferMRDC, and sends it to the SN via SRB3. The SN then sends the first indication information to the MN via interface signaling, or directly sends it to the MN via split SRB1. It should be noted that, in this implementation, the network pre-configures split SRB1 or SRB3.

[0335] In an embodiment of the present application, the first indication information is used to indicate the first target configuration that the MN is about to apply, and the first target configuration includes the new MCG configuration to be applied. Optionally, the first indication information is selected conditional reconfiguration identification information, etc. When the MN receives the identification information, the MN determines the MCG configuration that the UE is about to use, and determines the target MCG configuration applied by the network side according to the first indication information, so as to match the MCG applied by the terminal.

[0336] In the embodiment of the present application, when the first indication information is sent to the network device through the changed secondary cell group SCG, the method further includes one or more of the following:

[0337] Receiving third feedback information sent by the network device through the changed secondary cell group SCG;

[0338] Receiving scheduling information sent by the network device using a target MCG configuration; wherein the target MCG configuration is determined according to the first indication information; optionally, the target MCG configuration is an MCG configuration in the first target configuration;

[0339] Sending uplink information to the network device using the first target configuration;

[0340] After sending uplink information to the network device using the first target configuration, receiving downlink information sent by the network device in response to the uplink information;

[0341] Receive fourth feedback information sent by the network device to the terminal using the target MCG configuration after applying the target MCG configuration.

[0342] Using the configuration application method described in this embodiment, after performing continuous conditional cell addition / change, when the first indication information is sent to the network device through the changed secondary cell group SCG, in one implementation mode, optionally, after the network device sends feedback information to the UE through the changed SCG according to the first indication information, signaling / data interaction is performed between the UE and the network device; in another implementation mode, optionally, the network device updates the MCG configuration to the target MCG configuration according to the first indication information, and directly uses the target MCG configuration to schedule the UE, and after receiving the scheduling of the network device, the UE exchanges signaling / data with the network device; in another implementation mode, optionally, after sending the first indication information, the UE uses the first target configuration to directly send uplink information to the network device, and the network device provides feedback or sends related downlink information based on the uplink information sent by the UE, and then signaling / data interaction is performed between the UE and the network device; in another implementation mode, optionally, after the UE sends the first indication information, the network uses the target MCG configuration to send feedback information to the UE after applying the target MCG configuration.

[0343] It should be noted that the above-mentioned implementation modes are merely examples of the configuration application method described in the embodiments of the present application, and are not specifically limited to this.

[0344] The following is combined with a specific implementation method to illustrate an example of the implementation process in which the terminal performs continuous conditional cell addition / change in an embodiment of the present application, sends a first indication message to a network device to indicate a first target configuration to avoid causing an MCG underlying interruption and ensure that the configuration of the terminal matches that of the network side.
