In conjunction with the accompanying drawings, the conditions provided by the embodiments of the present application will be described below through some embodiments and their application scenarios. The processing method of software configuration, the processing device of conditional configuration, the terminal and the readable storage medium are explained in detail.

Please refer to Figure 2, which is a flow chart of a conditional configuration processing method provided by an embodiment of the present application. The conditional configuration processing method can be executed by a terminal. The terminal can be a terminal listed in the wireless communication system as shown in Figure 1. 11, or other types of terminals, which are not specifically limited here.

As shown in Figure 2, the processing method of this condition configuration can include the following steps:

Step 201: Reserve and/or release the conditional configuration according to the configuration processing policy. The conditional configuration includes at least one of conditional switching CHO configuration, conditional primary and secondary cell addition CPA configuration, and conditional primary and secondary cell change CPC configuration.

Wherein, the above-mentioned configuration processing policy may be the basis for judging the retention and/or release processing of at least part of the conditional configuration. The configuration processing policy may be issued by the network side device in real time or pre-agreed in the protocol, and is not specifically limited here. .

In implementation, the above-mentioned retention processing of conditional configurations according to the configuration processing policy can be: selecting the conditional configurations that need to be retained according to the configuration processing policy, retaining the conditional configurations, and releasing other unselected conditional configurations; the above-mentioned processing according to the configuration The processing strategy releases the conditional configuration, which can be: select the conditional configuration that needs to be released according to the configuration processing policy, release the conditional configuration, and retain the other unselected conditional configurations.

In some embodiments, the above step 201 can be understood as: in the scenario of SCG selective activation, when the Pcell is changed, the CPC/CPA configuration of the terminal can be released. For example, at least between the master nodes MN, when the Pcell changes, the terminal's CPC/CPA configuration can be released (this process can be achieved through explicit instructions from the network, FFS or other means).

It is worth noting that in related technologies, all conditional configurations are directly released in various processes, including: handover process, primary and secondary cell addition process, primary and secondary cell change process, T311 runtime during reconstruction, RRC The release process and the process of the UE entering the idle (IDLE) state will, without exception, release all conditional configurations used for conditional synchronization reconfiguration.

Different from the existing technology, the technical solution of this application does not directly release all conditional configurations, but determines whether the conditional configuration is released or retained, and releases or retains the corresponding conditional configuration according to the judgment result. In other words, in the related art, the configuration processing means is determined in any scenario or situation, while in the technical solution of this application, in different scenarios or situations, The processing methods for the same condition configuration are not certain, and in the same scenario, the processing methods for all condition configurations are not necessarily the same, and judgment needs to be made.

As an optional implementation manner, when the method of the embodiment of the present application is used in the handover process, the primary and secondary cell addition process, and the primary and secondary cell change process, in the handover process, the primary and secondary cell addition process, the primary and secondary cell addition process, and the primary and secondary cell change process, When the cell change process is a conditional switching process, a conditional primary and secondary cell addition process, and a conditional primary and secondary cell change process, before the conditional configuration is retained and/or released according to the configuration processing policy, the processing of the conditional configuration Methods also include:

Receive Radio Resource Control (RRC) synchronization reconfiguration message;

Access the target cell through the random access process.

The method of the embodiment of the present invention will be further described in detail below with respect to different scenarios.

scene one

The above-mentioned handover process may be a conditional handover process or a normal handover process (ie, a non-conditional handover process), and the above-mentioned target cell is the cell selected when the terminal executes the handover process.

Dual Connectivity (DC) provides UE with the resources of two network nodes (access network elements). One of the network nodes is called the master node (MN), and the other is called the secondary node (Secondary node). SN). At each network node, carrier aggregation technology (Carrier Aggregation, CA) is used, that is, UE is configured with a series of service cells controlled by the network node, also called cell group. The MN controls the Master Cell Group (MCG), and the SN controls the Secondary Cell Group (SCG). Each cell group contains a special cell (Special Cell, SpCell) and a series of secondary cells (Secondary Cell, Scell). The special cell in MCG is called Primary Cell (PCell), and the special cell in SCG is called Primary Secondary Cell (PSCell). In a cell group, SpCell uses the primary carrier, while other secondary cells use secondary carriers. Resource scheduling within a cell group is performed by SpCell.

In related technologies, in order to avoid the problem that the terminal cannot receive handover command related messages from the source node after the channel condition of the source cell deteriorates, causing handover failure, a conditional handover process is introduced.

During the conditional handover process, the UE performs cell handover-related measurements and reports the measurement report to the source node. When the source node decides to use CHO based on the measurement report and selects the target node, the source node sends an RRC containing the conditional handover to the UE. Reconfiguration (RRCReconfiguration) information (that is, the information carried in the above-mentioned RRC synchronization reconfiguration message). The UE responds to the RRCReconfiguration information, and sends an RRC Reconfiguration Complete (RRRCeconfigurationComplete) message to the source node. In this way, after completing the conditional handover configuration, the UE can evaluate whether the candidate cell meets the conditions based on the conditional handover configuration. If so, the UE selects the candidate cell as the target cell. Handover, for example: the UE initiates a random access process in the selected target cell, and the UE sends RRCReconfigurationComplete information to the target node. In related technologies, after the UE successfully completes the handover process, it will release the stored conditional handover configuration. In the embodiment of the present application, whether to retain or release the conditional handover configuration is determined according to the configuration processing policy.

Scene 2

The above-mentioned primary and secondary cell addition process may also be a conditional primary and secondary cell addition process or a common primary and secondary cell addition process. The above-mentioned target cell may be the cell selected when the terminal executes the primary and secondary cell addition process.

CPA is a process in which the UE evaluates the execution conditions and performs the addition of primary and secondary cells after the execution conditions are met. The CPA configuration may include the configuration of the candidate cell and execution conditions, and the execution conditions may include one or two trigger conditions.

The specific process of the CPA process is: the source node initiates the CPA process, the MN selects at least one candidate cell as the added target node, and sends an RRC reconfiguration message to the UE. The RRC reconfiguration message carries the CPA configuration. In this way, the UE completes the CPA. After configuration, you can evaluate whether the candidate cell meets the conditions according to the execution conditions in the CPA configuration. If it meets the conditions, select the candidate cell and add it as the primary and secondary cells, and send the RRC reconfiguration complete message. In this way, the UE can randomly access the selected cell. of the main and auxiliary communities.

In related technologies, after the UE successfully adds the primary and secondary cells, it will release the stored CPA configuration. In the embodiment of this application, after the UE successfully adds the primary and secondary cells, it will determine whether to retain the CPA configuration according to the configuration processing policy. Release processing.

Scene three

The above-mentioned primary and secondary cell change process may also be a conditional primary and secondary cell change process or a common primary and secondary cell change process. In this case, the above-mentioned target cell may be the cell selected when the terminal executes the primary and secondary cell change process.

CPC is the process in which the UE evaluates the execution conditions and performs the change of the primary and secondary cells after the execution conditions are met. After receiving the CPC configuration, the UE starts to evaluate the execution conditions, and the UE stops evaluating after the change of the primary and secondary cells is triggered. Evaluate execution conditions.

CPC configuration contains the configuration and execution conditions of CPC candidate cells. Execution conditions may contain one or two trigger conditions. In the related art, once the primary and secondary cell change process is successfully completed, the UE releases all stored CPC configurations. In the embodiment of this application, after successfully completing the primary and secondary cell change process, the UE will determine whether to retain or release the CPC configuration according to the configuration processing policy.

Among them, CPC includes at least one of the following situations:

Change of primary and secondary cell conditions within the secondary node (Intra-SN CPC);

Change of primary and secondary cell conditions between secondary nodes initiated by the primary node (MN initiated Inter-SN CPC);

The condition change of the primary and secondary cells between secondary nodes initiated by the secondary node (SN initiated Inter-SN CPC).

Taking the condition change of the primary and secondary cells between secondary nodes initiated by the secondary node as an example, the specific process of the CPC process is: the source secondary node (Source-SN, S-SN) initiates the CPC process, and the MN selects at least one candidate cell as the target to add. Secondary node (Target-SN, T-SN) and sends an RRC reconfiguration message to the UE. The RRC reconfiguration message carries the CPC configuration. In this way, after the UE completes the CPC configuration, it can evaluate based on the execution conditions in the CPC configuration. Whether the T-SN meets the conditions, if so, the UE sends an RRC reconfiguration complete message, and the UE can randomly access the selected T-SN.

For the CPC process of the above-mentioned change of primary and secondary cell conditions between secondary nodes initiated by the primary node or the change of primary and secondary cell conditions within the secondary node, please refer to the change of primary and secondary cell conditions initiated by the primary node between secondary nodes or the primary and secondary cell conditions within the secondary node in related technologies. Changed CPC process.

In this embodiment, after the UE successfully performs a cell handover or a primary and secondary cell change or a primary and secondary cell addition process, the UE can determine the conditional configuration of the cell handover or primary and secondary cell change or primary and secondary cell addition based on the configuration processing policy. And decide whether to retain or release the conditional configuration. In this way, the conditional configuration is disposed after the random access is completed, which can reduce the risk of interrupting the business process due to the conditional configuration being released before the random access is completed. In addition, if the conditional configuration is retained, the condition can be used in subsequent applications. Configure to continuously evaluate CHO and/or CPA and/or CPC, so that subsequent conditional switching, conditional primary and secondary cell changes, and conditional primary and secondary cell addition processes can proceed smoothly.

In the specific embodiment of the present invention, the ordinary handover process, ordinary primary and secondary cell change, and ordinary primary and secondary cell addition process are different from the conditional handover process, the conditional primary and secondary cell change process, and the conditional primary and secondary cell addition process, and are instruction-based processes. rather than a condition-based process.

As an optional implementation manner, the configuration processing policy is related to at least one of the following:

The first instruction information is used to instruct all conditional configurations to be retained or released;

The second indication information is used to indicate the conditional configuration that needs to be released or retained;

Type of RRC reconfiguration;

The source primary and secondary cells in the primary and secondary cell change process.

Wherein, the above-mentioned first indication information and second indication information may be indication information from a network side device, for example: the first indication information and/or the second indication information are configured through RRC synchronization reconfiguration carrying synchronization reconfiguration information. Message carrying, in this way, the RRC synchronization reconfiguration message carrying the synchronization reconfiguration information can be reused to transmit the first indication information and/or the second indication information, thereby reducing transmission overhead.

It is worth noting that the RRC synchronization reconfiguration information (reconfigurationWithSync) is a field of the RRC reconfiguration message. The RRC reconfiguration message carrying the RRC synchronization reconfiguration information (reconfigurationWithSync) carries the first indication information and/or the In the second indication information, after completing the synchronization reconfiguration, the terminal can perform retention and/or release processing of the conditional configuration according to the first indication information and/or the second indication information.

The configuration processing strategy is explained in further detail below.

Option one, the above configuration processing strategy related to the first indication information may be: judging whether to retain or release all conditional configurations according to the indication of the first indication information. For example: it may be indicated based on the first indication information that all CHO configurations, CPA configurations and CPC configurations need to be released, or it may be indicated that all CHO configurations, CPA configurations and CPC configurations need to be retained. In this way, the configuration processing strategy adopted by the terminal can be switched through the first indication information.

Option two, the above configuration processing strategy related to the second indication information may be: retaining the conditional configuration that needs to be retained indicated by the second indication information, and/or releasing the conditions that need to be released indicated by the second indication information. configuration.

In implementation, the second indication information may directly or indirectly indicate the conditional configuration that needs to be released or retained.

Optionally, the second indication information includes at least one of the following information:

Identification information of conditional configuration that needs to be released or retained;

The identification information of the cell or cell group corresponding to the condition configuration that needs to be released or retained.

For example: the second indication information may carry the ID of the conditional configuration that needs to be released or retained (such as condReconfigId), or the second indication information may carry the Cell ID to indicate which candidate cell's associated CPA configuration and/or CPC configuration needs to be released or retained. In this way, the second indication information can accurately indicate the conditional configuration that needs to be released or retained.

Option three, the above-mentioned type of RRC reconfiguration, can indicate: RRC reconfiguration is a synchronous reconfiguration in the handover process, an RRC reconfiguration in the primary and secondary cell change process, or an RRC reconfiguration in the primary and secondary cell addition process. In an implementation, RRC reconfiguration may be triggered by an RRC reconfiguration message carrying synchronized reconfiguration information.

The above configuration processing policy and the type of RRC reconfiguration may be: according to the type of RRC reconfiguration performed, the conditional configuration related to the type of RRC reconfiguration may be deleted.

Option four, the above configuration processing strategy and the source primary and secondary cells in the primary and secondary cell change process can be: release all conditional configurations related to the source PSCell, and retain other conditional configurations. In this way, after the terminal successfully executes the primary and secondary cell change process, the conditional configuration of the source primary and secondary cell in the primary and secondary cell change process is no longer needed in the subsequent CPC, thus the conditional configuration related to the source primary and secondary cell can be released to save the terminal storage resources and simplify the terminal’s subsequent evaluation of CPC complexity.

It is worth mentioning that during implementation, at least two of options one to four related to the above configuration processing strategy can be combined.

In scenario 1, when the UE performs the cell handover process (such as receiving a handover command or judging that the handover condition is established), and after completing the cell handover, the configuration processing strategy may include any of the following:

Release all CHO configurations and retain all CPA configurations and/or CPC configurations;

Release all CHO configurations. For CPA configurations and/or CPC configurations, it can be determined whether to release or retain all CPA configurations and/or CPC configurations based on the first indication information in the switching command;

For CHO configuration and/or CPA configuration and/or CPC configuration, it is judged to release or retain all CPA configuration and/or CPC configuration based on the first indication information in the switching command;

For the CHO configuration and/or CPA configuration and/or CPC configuration, the retention or release processing is performed according to the CPA configuration and/or CPC configuration that needs to be released or retained indicated by the second instruction information in the switching command.

It should be noted that the above-mentioned first indication information and/or the second indication information may also be carried in other messages besides the above-mentioned switching command, and no specific limitation is constituted here.

In scenario two, when the UE executes the primary and secondary cell addition process (such as receiving the PSCell addition command from the network side device or judging that the primary and secondary cell addition conditions are established), after successfully adding the primary and secondary cells, the configuration processing strategy can include Any of the following:

Release all CPA configurations and retain the CHO configuration and CPC configuration, or, if the network side device indicates that the first type of CPA configuration is used for CPA and CPC, retain the first type of CPA configuration, the CHO configuration and The CPC configuration;

Release all CPA configurations, and retain or release all CHO configurations and CPC configurations according to the first instruction information in the PSCell addition command;

Release all CPA configurations, and retain or release the CHO configurations and CPC configurations that need to be retained or released as indicated by the second instruction information in the PSCell addition command;

In scenario three, when the UE executes the primary and secondary cell change process (such as receiving a PSCell change command from the network side device or judging that the primary and secondary cell change conditions are met), after successfully changing the primary and secondary cells, the configuration processing strategy may include Any of the following:

Release all CPC configurations and retain the CHO configuration and CPA configuration, or, if the network side device indicates that the second type of CPC configuration is used for CPA and CPC, retain the second type of CPC configuration, the CHO configuration and The CPA configuration;

Release all CPA configurations and/or CPC configurations related to the source primary and secondary cells, retain CPA configurations and/or CPC configurations related to other primary and secondary cells, and retain the CHO configuration.

Release all CPC configurations, and follow the first instruction information in the PSCell change command to retain or release all CHO configurations and CPA configurations;

Release all CPC configurations, and retain or release the CHO configuration and CPA configuration that need to be retained or released as indicated by the second instruction information in the PSCell change command;

Release all CPA and/or CPC configurations and retain the CHO configuration;

Release all CPA and/or CPC configurations, and retain or release all CHO configurations according to the first instruction information in the PSCell change command

Release all CPA and/or CPC configurations, and retain or release the CHO configuration indicated by the second instruction information in the PSCell change command;

The CHO configuration and/or CPA configuration and/or CPC configuration indicated by the second indication information in the PSCell change command are retained or released.

It should be noted that the above-mentioned first instruction information and/or the second instruction information can also be carried in other messages besides the above-mentioned PSCell change command, and no specific limitation is constituted here.

In some scenarios, the CHO configuration can be associated with the CPA configuration and/or CPC configuration, for example, associated with the same cell, or the CHO configuration and the CPA configuration and/or CPC configuration are described by the same configuration, etc. In this case, before performing the handover When the process releases the CHO configuration, the CPA configuration and/or CPC configuration associated with the CHO configuration will also be released.

As an optional implementation manner, when the target cell is the cell selected when the terminal performs the handover process, the configuration processing strategy is a strategy for processing CPA configuration and/or CPC configuration, and the configuration The processing policy is related to at least one of the following information:

Cell information of the candidate cell corresponding to the CPA configuration and/or CPC configuration;

Handover type information for the handover performed;

Information related to the CPA configuration and/or CPC configuration and the target cell.

The above handover process can be a conditional handover process, that is, a handover initiated by the terminal when the handover condition sent by the network side is met, or a normal handover process, that is, a handover performed directly according to a direct handover command from the network side.

In this embodiment, after executing the switching process, all CHO configurations may be released, and the CPA configuration and/or CPC configuration may be retained and/or released according to the configuration processing policy.

Option 1: Based on the cell information of the above-mentioned candidate cells, it can be judged whether it can continue in the future. Use the CPA configuration and/or CPC configuration associated with the candidate cell. The above configuration processing strategy is related to the cell information of the candidate cell corresponding to the CPA configuration and/or CPC configuration, and may be: if the CPA configuration and/or CPC configuration associated with the candidate cell cannot continue to be used, then release the CPA associated with the candidate cell. configuration and/or CPC configuration, if the CPA configuration and/or CPC configuration associated with the candidate cell can continue to be used, the CPA configuration and/or CPC configuration associated with the candidate cell will be retained.

For example: the cell information of the above candidate cell may indicate at least one of the following:

Whether the candidate cell has a key that can continue to be used or has an unfinished key update process. If the candidate cell has a key that can continue to be used or the key update process has been completed, the CPA configuration associated with the candidate cell can be retained. and/or CPC configuration, otherwise the CPA configuration and/or CPC configuration associated with the candidate cell can be released;

Whether the candidate cell and the PCell after handover have an open interface (Xn interface).

The CPA configuration and/or CPC configuration associated with the candidate cell;

Whether the conditional reconfiguration of the candidate cell is an incremental configuration (Delta configuration). If the conditional reconfiguration of the candidate cell is not a Delta configuration, the CPA configuration and/or CPC configuration associated with the candidate cell can be retained, otherwise the candidate can be released. Cell-associated CPA configuration and/or CPC configuration.

Option two, the handover type information of the above conditional handover can indicate whether the handover process is an intra-CU handover between different centralized units (Centralized Unit, CU) or an inter-CU handover within the same CU, that is, whether the gNB-CU is switched, where , the configuration processing policy is related to the handover type information of the handover performed, which can be that if the gNB-CU is not switched during the handover process, the CPA configuration and/or CPC configuration can be retained, otherwise the CPA configuration and/or CPC configuration can be released.

Option three, the correlation between CPA configuration and/or CPC configuration and the target cell is implemented in two ways:

At this time, the correlation information between the above configuration processing policy and CPA configuration and/or CPC configuration and the target cell can be: if the new PCell after the handover is completed is a specific PCell, and the PCell ID and conditional primary and secondary cells are changed If the PCell ID carried in the (Conditional PSCell Addition Change, CPAC) configuration is the same, the CPA configuration and/or CPC configuration can be retained, otherwise the CPA configuration and/or CPC configuration can be released;

2) The CPA configuration and/or CPC configuration and the CHO configuration are associated together, or described by the same configuration. (For ease of explanation, in the following embodiments, the associated CPA configuration and/or CPC configuration and CHO configuration are recorded as CHO+ CPAC configuration). At this time, the correlation information between the above configuration processing strategy and the CPA configuration and/or the CPC configuration and the target cell can be: if the PCell after the handover is completed is the PCell in the CHO+CPAC configuration, the CHO+CPAC configuration is retained CPAC configuration in .

Step 1: The network side device sends RRC synchronization reconfiguration information (reconfigurationWithSync) to the UE. The RRC synchronization reconfiguration information is included in the configuration of the MCG (included in spCellConfig of an MCG).
