Technical Field The present application relates to the field of communication technology, and in particular to a wireless communication configuration method, device, and storage medium. Background Art In related technologies, when a terminal device migrates to the RRC (Radio Resource Control) inactive state (RRC_INACTIVE) in a DC (Dual Connectivity) scenario, the corresponding CPAC (Conditional PSCell Addition / Change) pre-configuration information is released. Therefore, when the terminal device migrates from RRC_INACTIVE to RRC_CONNECTED (Radio Resource Control Connected State), or when the terminal device performs a cell handover, the network device needs to resend the CPAC pre-configuration information to the terminal device, resulting in a large downlink signaling overhead and the interruption of data transmission and handover due to state migration.

Wireless communication between communication devices may include: wireless communication between network devices and terminals, wireless communication between network devices and network devices, and wireless communication between terminals. In the embodiments of the present application, the term "wireless communication" may also be referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission". Those skilled in the art may apply the technical solutions provided in the embodiments of the present application to wireless communication between network devices and terminals, such as wireless communication between access network devices and terminals, and wireless communication between core network devices and terminals. The application scenario of the embodiment of the present application is a dual connectivity (DC) scenario as shown in Figure 2. In Figure 2, MCG (Master cell group), SCG (Secondary cell group), Pcell (Primary cell), PScell (Primary Secondary cell), Scell (Secondary cell). Furthermore, for a terminal device connected to a network device, in RRC_IDLE (radio resource control idle state), when the quality of the wireless link of the current serving cell is poor or there is an adjacent serving cell with better service quality or the currently connected network device needs to be load balanced, the terminal device will trigger a handover and perform a serving cell handover. The entire handover process includes three stages: handover preparation, handover execution, and handover completion. The specific handover process, referring to Figure 3, includes the following steps: S300. Mobility control information provided by AMF. Before S300 , before cell switching, user data is transmitted between the terminal device and the source network device, and between the source network device and the source UPF (User Plane Function). Specifically, S300 indicates that the AMF provides mobility control information to the source network device and the target network device. S301. Measurement control and reporting. The terminal device sends measurement control and reports to the source network device. S302: Handover decision. The source network device determines whether to switch the serving cell based on the measurement control and report, and determines the target network device of the target cell if the serving cell needs to be switched. S303: Handover request. Among them, after determining the service cell of the switching terminal device, the source network device sends a switching request to the target network device. S304: Access control. The target network device determines whether to allow the terminal device to switch the service cell. S305: Confirm the switching request. When the target network device allows the terminal device to switch the serving cell, a switching request confirmation is sent to the source network device to indicate that the source network device agrees to the switching. S300 to S305 are the handover preparation stage, and after the handover preparation is completed, the subsequent handover execution process is executed. S306: Initiate RAN handover. The terminal device and the source network device both initiate a RAN handover, and the source network device then transfers the cache data and new data from the source UPF (User Plane Function), and the terminal device detaches and synchronizes from the old serving cell to the new serving cell. S307a: Advance state migration. S307b: SN state transition. Then the user data in the source UPF is transferred to the target network device through the source network device. Further, the target network device buffers the user data from the source network device. S308: RAN switching is completed. Among them, S308 includes: S308a, switching success and S308b, SN state transfer. In the embodiment of the present application, S306 to S308 are the switching execution process. S309: Path switching request. The target network device sends a path switching request to the AMF. S310: Path switching in source UPF. Among them, AMF performs path switching in the source UPF after receiving the path switching request. After the path switching is completed, the source UPF sends an end mark to the target network device through the source network device. In addition, the target network device is configured with user data. S311: Path switching request confirmation. After the path switching is completed, the AMF sends a path switching request confirmation to the target network device. S312: UE context release. After implementing the path switch, the target network device instructs the source network device to release the UE context. It can be seen that S309 to S312 is the process of handover completion. In an embodiment of the present application, after going through the process shown in FIG3 , the terminal device can implement the switching of the service cell. In the embodiment of the present application, CPAC is involved in the dual connectivity scenario, and the switching of the primary cell and CPAC need to be considered at the same time. For example, referring to Figure 4, the process of adding a conditional SN (Secondary Node) triggered by the MN (Master Node) specifically includes the following steps: S401a, SgNB add request. When a terminal device accesses the network, it first connects to the master node and then adds secondary nodes as needed. The master node, also known as the "anchor," is responsible for interacting with the core network's control plane. The multiple cells within the master node are called a master cell group (MCG), and the corresponding multiple cells within the secondary node are called a secondary cell group (SCG). Specifically, SgNB represents a secondary base station, and the master node sends a secondary base station addition request to the SN, where the secondary base station addition request adds the SN. S401b, SgNB add request. The master node sends a secondary base station adding request to other optional SNs, where the secondary base station adding request is used to request to add other optional SNs. S402a, SgNB adds the request confirmation. The SN sends an SgNB add request confirmation to the MN. S402b, SgNB add request confirmation. Among them, other optional SNs send SgNB addition request confirmation to MN. S403: RRC connection reconfiguration. The MN sends an RRC connection reconfiguration to the terminal device. Furthermore, the RRC connection reconfiguration includes MN RRC connection configuration and SN RRC reconfiguration. The RRC connection reconfiguration is used to instruct the terminal device to reconfigure the RRC connection. S404: RRC connection reconfiguration is completed. After the terminal device completes the RRC connection reconfiguration, it sends the RRC connection reconfiguration completion to the MN. Furthermore, RRC connection reconfiguration completion includes SN RRC reconfiguration completion. S405a, SgNB reconfiguration is completed. Among them, MN sends SgNB reconfiguration completion to SN. S405b, SgNB release. The MN sends an SgNB release to other optional SNs. Furthermore, SgNB release is used to indicate other optional SN release related contexts. S405c, SgNB release request confirmation. Among them, after releasing the relevant context, other optional SNs reply to the MN with SgNB release request confirmation. S406: Random access process. S407: SN status transfer. The SN state transfer is to switch the SN to the secondary base station of the terminal device. S408: Data forwarding. During the path update process, the S-GW converts the relevant data to the newly switched SN. In the embodiment of the present application, S-GW (Serving GateWay) is a gateway that terminates at the E-UTRAN interface. S409, E-RAB modification indication. During the path update process, the MN sends an E-RAB modification indication to the MME. In the embodiment of the present application, MME (Mobility Management Entity) is a key control node of the 3GPP protocol LTE access network. It is responsible for the positioning of UE (User Equipment) in idle mode, the paging process, including relay. Simply put, MME is responsible for the signaling processing part. Furthermore, E-RAB (Evolved Radio Access Bearer) refers to the bearer of the user plane, which is used to transmit voice, data and multimedia services between the terminal device and the CN (Core Network). Among them, the MN sends an E-RAB modification indication to the MME to instruct the MME to modify the E-RAB to the SN. S410: Bearer modification. Among them, the bearer modification is performed between the S-GW and the MME. S411, end marker packet. After the handover of the secondary base station is completed, the S-GW sends an end marker packet to the SN to inform the SN that the handover of the secondary base station has been completed. S412, E-RAB modification confirmation. After the MME modifies the E-RAB, it sends an E-RAB modification confirmation to the MN. Referring to Figure 5, CPAC is triggered by the SN, where SRB 3 (SRB defined in 3GPPTS 38.331) is established between the SN and the UE. The SRB (Signalling Radio Bearer) can use SRB3 to configure the CPAC pre-configuration information of the terminal device. When the configuration conditions of the pre-configuration information are met, the UE accesses the candidate cell corresponding to the pre-configuration information according to the pre-configuration, without the participation of the MN. Figure 5 shows that the SN controls the UE's CPAC (Conditional PSCell Change, conditional primary and secondary cell update), which specifically includes the following steps: S501, NR RRC reconfiguration. The secondary base station sends an NR RRC reconfiguration to the terminal device, where the NR RRC reconfiguration carries the pre-configuration information of the CPAC. S502. NR RRC reconfiguration is completed. Among them, the terminal device configures the pre-configuration information of CPAC, and sends NR RRC reconfiguration completion to SN after the configuration is completed. S503: Random access process. S504. NR RRC reconfiguration is completed. Among them, when the terminal device completes the configuration of the CPAC pre-configuration information, it sends the NR RRC reconfiguration completion to the SN. As can be seen in FIG5 , the pre-configuration information of CPAC can be sent to the terminal device through the SN without the participation of the MN, thereby implementing the configuration of the pre-configuration information of CPAC. 6, the SN update process specifically includes the following steps: S601. SgNB change request. Among them, first, the MN sends an SgNB change request to the S-SN (source secondary node) to request a change of the SgNB. S602a, SgNB add request. Among them, the MN sends an SgNB add request to the T-SN (target secondary node) to request that the T-SN be changed to the SgNB of the information. S602b, SgNB add request. Among them, the MN sends an SgNB add request to other optional T-SNs to request that other optional T-SNs be changed to the SgNB of the information. S603a, SgNB adds the request confirmation.

Among them, the S-SN sends an SgNB modification request confirmation to the SgNB. S606: RRC connection reconfiguration. The MN sends an RRC connection reconfiguration to the terminal device. The RRC connection reconfiguration includes MN RRC connection reconfiguration and T-SN RRC reconfiguration, and may also include S-SN RRC reconfiguration. The T-SN is the target secondary node to be switched, and the S-SN is the source secondary node to be switched. S607: RRC connection reconfiguration is completed. The RRC connection reconfiguration completion includes: S-SN RRC reconfiguration completion. S608. SgNB change confirmation. S609a. Modify the SgNB request.

The RRC connection reconfiguration completion includes T-SN RRC-reconfiguration completion. S611a, SgNB release request. Among them, after receiving the RRC connection reconfiguration completion sent by the terminal device, the MN sends an SgNB release request to the S-SN to request S-SN to release related information. S611b, SgNB release request confirmation. Among them, after releasing the relevant information, the S-SN sends an SgNB release request confirmation to the MN. S612a, SgNB reconfiguration is completed. Among them, the MN sends the SgNB reconfiguration completion to the T-SN. S612b, SgNB release request. Among them, the MN sends an SgNB release request to other optional T-SNs to indicate other optional T-SN release related information. S612c, SgNB issues a request confirmation. Among them, other optional T-SNs reply to the MN with SgNB release request confirmation after releasing the relevant information. S613: Random access process. S614a: SN status transfer. S614b: SN status transfer. S615: Data forwarding. S616: Assist in RAT data usage reporting. Among them, RAT (radio access technology), S-SN sends the auxiliary RAT data usage report to MN. S617, E-RAB modification indication. S618, bearer modification. S619: End marker packet. S620, new path. S621, E-RAB modification confirmation. S622: UE context release. In Figure 6, this is to achieve SN switching. During the SN switching process, an RRC connection reconfiguration is sent to the terminal device, and the RRC connection reconfiguration carries the pre-configuration information of the CPAC, so that the terminal device uses the pre-configuration information of the CPAC for communication. Furthermore, in the new radio dual-connectivity scenario (NR-DC), the pre-configuration information of CPAC received by the terminal device includes: two independent conditional reconfigurations. One is the conditional reconfiguration associated with MCG, which is carried in the RRC reconfiguration message received via SRB1. The other is the conditional reconfiguration associated with SCG, which is carried in the RRC reconfiguration message received via SRB3, or in the RRC reconfiguration message within the RRC reconfiguration message received via SRB1. Add the pre-configuration information of CPAC in the condreconfig of the network device. Currently, in the following three situations, the terminal device will clear the CPAC pre-configuration information sent by the network device. (1) CPAC completed by the UE: Specifically, CPAC is defined as the addition or change of a PSCell (PSCell) executed by the terminal when the execution conditions are met. The terminal device begins evaluating the execution conditions upon receiving the pre-configuration information of CPAC. Once a PSCell addition or PCell change is triggered, the evaluation of the execution conditions is stopped and the pre-configuration information of CPAC is cleared. Furthermore, the following principles apply to CPAC: The pre-configuration information of CPAC contains the configuration of the candidate PSCell, the execution conditions, or the MCG configuration information applied when triggering CPAC execution. In addition, an execution condition can be composed of one or two trigger conditions, and only one RS (communication interface) type and a maximum of two different trigger quantities can be used to evaluate the execution conditions of a single candidate PSCell. Furthermore, before any execution conditions for CPAC are met, upon receiving a PSCell add command or a PCell change command, the terminal device executes the PSCell add process in the standard, or the PCell change process in the standard, regardless of any previously received pre-configuration information of CPAC. Upon successful completion of the PSCell add process or the PCell change process, the UE releases the stored pre-configuration information. When executing CPAC, the UE does not need to continue to evaluate the execution conditions of other candidate PSCells or PCells. Once CPAC is successfully executed, the UE releases all stored pre-configuration information of CPAC. In the prior art, the pre-configuration information of CPAC does not support HO (Handover) commands, PSCell addition commands or any conditional reconfiguration. (2) The UE migrates to the RRC_INACTIVE state or the RRC_IDLE state: Specifically, when the terminal device receives an RRC release message sent by the network device that carries configuration suspension information or the terminal device enters the RRC_IDLE state, all CPAC pre-configuration information is cleared. (3) SCG releases and deletes the pre-configuration information corresponding to SCG in the pre-configuration information of CPAC. In the (NG) EN-DC scenario or the NR-DC scenario, due to the release of the SCG triggered by E-UTRA, the pre-configuration information corresponding to all SCGs in the SCG VarConditionalReconfig (a storage space for pre-configuration information) will be cleared. In the NR-DC scenario, due to the release of the SCG triggered by NR, the RRC Reconnfig in the condRRCReconfig (RRC reconfiguration) in the MCG VarConditionalReconfig is deleted, and all entries of the MCG with synchronous reconfiguration (reconfigurationWithSync) are not deleted. Furthermore, in the EN-DC scenario, according to TS 36.331 in the standard,

[0010] The provisions of the clauses shall unconditionally execute the deletion of CPAC's pre-configured information In summary, the concept of CPAC was introduced in Rel-17. Currently, in dual connectivity (DC) scenarios, CPAC is often involved due to changes in service conditions or channel quality. When service conditions or channel quality change, CPAC is determined to be executed, and the source master node (S-MN) initiates a CPAC request and related configuration information request to the target master node (T-MN). The S-MN then configures multiple candidate PScells (primary and secondary cells) and corresponding trigger conditions to the terminal device; the terminal device evaluates the trigger conditions, and when at least one PScell is found to meet the conditions, it initiates a RACH (Random Access Channel) to the determined PScell primary and secondary cells to complete CPAC. As can be seen, currently, when a terminal device migrates from wireless RRC_INACTIVE to RRC_CONNECTED, or when the terminal device performs a cell handover, the network device needs to resend the CPAC pre-configuration information to the terminal device, resulting in large downlink signaling overhead and the interruption of data transmission and handover due to state migration. In this regard, an embodiment of the present application proposes a wireless communication configuration method, the main inventive idea of which is as follows: by obtaining and saving the pre-configuration information added or updated by the conditional primary and secondary cells; obtaining indication information; and retaining the pre-configuration information added or updated by the conditional primary and secondary cells when migrating to the wireless resource control inactive state based on the indication information. It can be achieved that if the terminal device still accesses the service cell or the service cell corresponding to the pre-configuration information of the CPAC next time, it can instruct the network device and continue to use the pre-configuration information of the CPAC, thereby saving downlink signaling overhead, reducing the interruption impact of state migration on data transmission and switching, and improving user experience. The technical solutions shown in this application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated. FIG7 is a schematic diagram of a wireless communication configuration method according to an embodiment of the present application. As shown in FIG7 , the wireless communication configuration method according to the present embodiment is applied to a terminal device, and the wireless communication configuration method includes: S701. Acquire and save pre-configuration information of adding or updating conditional primary and secondary cells. In summary, the CPAC pre-configuration information can be delivered to the terminal device by the SN via an SRB3 established with the terminal device. Alternatively, the SN can forward the CPAC pre-configuration information to the mobile node, which then delivers it to the terminal device via an SRB3 established with the terminal device. Furthermore, specific configuration information is delivered via a "condreconfig (network conversion configuration file)" IE (information element). Upon receiving the CPAC pre-configuration information, the terminal device saves the CPAC pre-configuration information. In summary, referring to Figures 4 to 6, the MN or SN sends an RRC connection reconfiguration to the terminal device, and the RRC connection reconfiguration carries the pre-configuration information of CPAC. After receiving the pre-configuration information of the CPAC, the terminal device saves the pre-configuration information of the CPAC in the VarConditionalReconfig variable. In the embodiment of the present application, the pre-configuration information of CPAC includes: at least one of the following: air interface resources of candidate cells, non-access stratum signaling (NAS signaling), primary cell group (MCG) configuration information, secondary cell group (SCG) configuration information, measurement configuration information, dedicated system information block (System Information Block, abbreviated as SIB), and encryption parameters. Among them, the pre-configuration information of CPAC can pre-configure information of up to 8 candidate primary and secondary cells, and a maximum of two measurement events can be configured. Among them, the candidate cell refers to the cell adjacent to the service cell accessed when the terminal device obtains and saves the pre-configuration information of CPAC, and is the cell that the terminal device may switch to. The air interface resources of the candidate cell include one or more of the PDCCH (Physical Downlink Control Channel) / PUCCH (Physical Uplink Control Channel) / PDSCH (Physical Downlink Shared Channel) / PUSCH (Physical Uplink Shared Channel) physical channel time-frequency resources and parameter configurations for uplink and downlink data transmission, the target cell measurement for the UE to perform L1 and / or L3 measurement, pilot time-frequency resources, TCI (Transmission Control Interface) status, measurement reporting period, measurement reporting events and corresponding parameters, and measurement reporting amount. The dedicated system information block includes one or more of the corresponding SB (Scheduling Block) time-frequency resources and the broadcast RNTI (Radio Network Temporary Indentifier). The encryption parameters include one or more of the encryption algorithm and initialization parameters. In an embodiment of the present application, the terminal device receives the pre-configuration information of the CPAC sent by the source network device in the first service cell, and then saves the pre-configuration information of the CPAC. S702: Obtain instruction information. The indication information is carried in the radio resource control release message. Referring to Figure 8, the RRC release message is sent by the source network device to instruct the terminal device to migrate to the RRC_INACTIVE state. The terminal device then migrates to the RRC_INACTIVE state and continues to retain the pre-configured CPAC information in the VarConditionalReconfig variable. Furthermore, the radio resource control release message carries at least one of a timer, a cell identifier of a valid cell, and a radio notification area list of a valid area. The timer is used to indicate the valid time of the pre-configuration information added or updated by the conditional primary and secondary cells. The cell identifier of the valid cell and the radio notification area list of the valid area are both used to indicate the applicable cells of the pre-configuration information added or updated by the conditional primary and secondary cells. It also includes: if the timer expires and / or the terminal device leaves the valid cell, deleting the pre-configuration information added or updated by the conditional primary and secondary cells. When migrating to the radio resource control idle state, the pre-configuration information added or updated by the conditional primary and secondary cells is deleted. Specifically, the timer is used to indicate the validity period of the saved CPAC pre-configuration information. For example, if the timer is 1 hour, the saved CPAC pre-configuration information is valid within 1 hour. When the time limit of the timer is exceeded, the terminal device clears the saved CPAC pre-configuration information. In addition, the cell identifier of the valid cell is used to indicate the applicable cell for the saved CPAC pre-configuration information. For example, if the cell identifier is cell 1, cell 3, and cell 5, the terminal device can use the saved CPAC pre-configuration information only when it accesses cell 1, cell 3, and cell 5. The saved CPAC pre-configuration information cannot be used in cells other than cell 1, cell 3, and cell 5, and the saved CPAC pre-configuration information is also deleted when the terminal device leaves these valid cells. The wireless notification area list includes multiple RNAs, and the CPAC pre-configuration information can only be applied when the access cell is under the multiple RNAs. Among them, if the wireless resource control release message carries a timer, the terminal device starts the timer when receiving the wireless resource control release message. Furthermore, before the timer expires, if the terminal device accesses the first service cell, or the cell accessed by the terminal device is a candidate cell in the pre-configuration information of CPAC, the terminal device can perform relevant configuration according to the pre-configuration information of CPAC. S703: When migrating to the radio resource control inactive state based on the indication information, retain the pre-configuration information added or updated by the conditional primary and secondary cells. Among them, the indication information sent by the source network device is used to instruct the terminal device to migrate from RRC_CONNECTED to RRC_INACTIVE and continue to save the pre-configuration information of CPAC. In an embodiment of the present application, after retaining the pre-configuration information for adding or updating the conditional primary and secondary cells, the method further includes sending a first message to a network device, where the first message is used to indicate that the pre-configuration information for adding or updating the conditional primary and secondary cells is available. The first message includes: a terminal device identifier and / or a candidate cell identifier, where the candidate cell identifier is a cell identifier of a candidate cell in the conditional primary and secondary cell addition or update. In an optional embodiment, the first information is carried in a notification area update message based on a wireless notification area. If the terminal device needs to update the RNA, it sends an RNAU (RAN-based Notification Area Update) message to the network device, where the RNAU message carries the first information, indicating that the network device has stored the pre-configured information of the CPAC. In an optional embodiment, the radio resource control recovery request message further carries a measurement report, which is obtained in advance by the terminal device according to pre-configured information of the stored CPAC. Furthermore, it also includes: obtaining second information indicating a processing method for pre-configuration information added or updated by the conditional primary and secondary cells; and performing corresponding processing on the pre-configuration information added or updated by the conditional primary and secondary cells according to the processing method. The processing method includes: retaining the pre-configuration information added or updated by the conditional primary and secondary cells, deleting the pre-configuration information added or updated by the conditional primary and secondary cells, updating the pre-configuration information added or updated by the conditional primary and secondary cells, or adding one of the pre-configuration information added or updated by the conditional primary and secondary cells. In Example 1, referring to FIG9 , the terminal device sends an RRC recovery request message to the source network device in the second serving cell, wherein the RRC recovery request message carries the first information. The second serving cell and the first serving cell are the same cell or different cells, and the second serving cell is the cell served by the source network device. FIG9 specifically includes the following steps: S901, RRC release message. Among them, the terminal device executes S701 to S703 when in the first service cell. In an embodiment of the present application, when the terminal device is in RRC_CONNECTED, it receives an RRC release message sent by the source network device. The RRC release message carries 1-bit indication information instructing the terminal device to migrate to RRC_INACTIVE and retain the pre-configured information of the CPAC. S902. Migrate to RRC_INACTIVE. Among them, the terminal device migrates from RRC_CONNECTED to RRC_INACTIVE according to the instruction information in the RRC release message. S903: Reserve the pre-configured information of the CPAC. The terminal device continues to retain the pre-configured information of the CPAC according to the instruction of the instruction information. S904: RRC recovery request message. In an optional embodiment, the terminal device accesses the current cell (the second service cell and the first service cell are the same cell) or accesses other cells under the same source network device (the second service cell and the first service cell are not the same cell), and the terminal device sends an RRC recovery request message to the source network device. The RRC recovery request message carries first information, and the first information is used to indicate that the pre-configuration information of the CPAC is available, that is, the terminal device saves the pre-configuration information of the CPAC. The first information includes: a terminal device identifier and / or a candidate cell identifier, and the candidate cell identifier is a cell identifier of the candidate cell in the pre-configuration information of the CPAC. S905: RRC recovery message. The terminal device receives an RRC recovery message sent by the source network device, and the RRC recovery message carries second information. Further, the second information indicates a processing method for the CPAC pre-configuration information; the terminal device can perform corresponding processing on the CPAC pre-configuration information according to the processing method. In FIG9 , the second serving cell and the first serving cell correspond to the same network device, ie, the source network device. In an optional embodiment, referring to FIG10 , the terminal device sends an RRC recovery request message to the target network device in a second serving cell, where the second serving cell is a cell served by the target network device, wherein the RRC recovery request message carries the first information. The second serving cell and the first serving cell are different cells, and the target network device is different from the source network device. FIG8 specifically includes the following steps: S1001. RRC release message. S1002. Migrate to RRC_INACTIVE. S1003: Save the pre-configuration information of the CPAC. Among them, S1001 to S1003 refer to S1001 to S1003 and will not be repeated here. S1004. RRC recovery request message. S1005. RRC recovery message. Among them, S1004 and S1005 are the interactions between the terminal device and the target network device. Other contents refer to S904 to S905 and will not be repeated here. Furthermore, in an embodiment of the present application, the processing method includes: retaining the pre-configuration information of the CPAC, deleting the pre-configuration information of the CPAC, updating the pre-configuration information of the CPAC, or adding the pre-configuration information of the CPAC. Specifically, retaining the pre-configuration information of CPAC means that if the pre-configuration information of CPAC is available, the terminal device can continue to save the pre-configuration information of CPAC. Deleting the pre-configuration information of CPAC means that if the pre-configuration information of CPAC is unavailable, the saved pre-configuration information of CPAC is deleted and the pre-configuration information of CPAC is reconfigured. Updating the pre-configuration information of CPAC means that if part of the pre-configuration information of CPAC saved in the terminal device is available and part is unavailable, the available part of the pre-configuration information of CPAC is retained and the unavailable part of the pre-configuration information of CPAC is replaced. Adding the pre-configuration information of CPAC means adding some pre-configuration information to the original pre-configuration information of CPAC. In an embodiment of the present application, the terminal device can perform measurements in advance based on the pre-configured information of CPAC to obtain a measurement report. When the state of the terminal device migrates (for example, from RRC_INACTIVE to RRC_CONNECTED), the measurement report can be sent to the network device, so that the mobility performance of the terminal device after the state migration can be quickly guaranteed, reducing the greater interruption delay caused by the terminal device state migration. This application can achieve that if the terminal device still accesses the current service cell or the service cell corresponding to the CPAC's pre-configuration information next time, it can instruct the network device and continue to use the CPAC's pre-configuration information, thereby saving downlink signaling overhead, reducing the impact of state migration on data transmission and switching interruptions, and improving user experience. 11 , a method for configuring wireless communication is shown, which is applied to a network device that a terminal device accesses in a second serving cell, including the following steps: S1101. Obtain first information, where the first information indicates that pre-configured information added or updated for conditional primary and secondary cells is available. The first information is carried in a radio resource control recovery request message. The first information includes: a terminal device identifier and / or a candidate cell identifier, where the candidate cell identifier is a cell identifier of a candidate cell in conditional primary or secondary cell addition or update. Among them, it also includes: obtaining the pre-configuration information of the conditional primary and secondary cells added or updated according to the terminal device identifier and / or the candidate cell identifier; determining the processing method of the pre-configuration information of the conditional primary and secondary cells added or updated, and indicating the second information, and the second information is used to indicate the processing method of the pre-configuration information of the conditional primary and secondary cells added or updated. In an embodiment of the present application, obtaining pre-configuration information for adding or updating conditional primary and secondary cells includes: obtaining pre-configuration information for adding or updating conditional primary and secondary cells from a source network device, where the source network device is a service network device that configures the configuration information for adding or updating conditional primary and secondary cells for the terminal device. Among them, determining the processing method of the pre-configuration information added or updated by the conditional primary and secondary cells includes: obtaining the resource usage of the second service cell and the neighboring cells of the second service cell, the second service cell is the cell currently accessed by the terminal device; obtaining the measurement report carried by the wireless resource control recovery request message; obtaining whether the terminal device needs to configure a dual-connection scenario; determining the processing method of the pre-configuration information added or updated by the conditional primary and secondary cells based on the resource usage, the measurement report and whether the terminal device needs to configure a dual-connection scenario. Furthermore, the processing method includes: retaining the pre-configuration information added or updated by the conditional primary and secondary cells, deleting the pre-configuration information added or updated by the conditional primary and secondary cells, updating the pre-configuration information added or updated by the conditional primary and secondary cells, or adding one of the pre-configuration information added or updated by the conditional primary and secondary cells. Specifically, resource usage includes physical resource usage, user load, and processing resource capacity. The source network device determines whether to continue to reserve resources of the candidate cell in the CPAC pre-configured information for the target user based on these resource usage. Furthermore, the second information can be a 1-bit indication information. If the indication information is 0, it indicates deletion of the CPAC pre-configuration information; 1 indicates continued retention of the CPAC pre-configuration information; or the second information can be a 2-bit indication information. If the indication information is 00, it indicates deletion; if the indication information is 01, it indicates subsequent reconfiguration (update); if the indication information is 11, it indicates continued retention or re-issuance of a new set of CPAC pre-configuration information. The candidate cell identifier is used as an index. If the newly configured candidate cell identifier is consistent with an identifier of the configuration information of the originally retained candidate cell, check whether there is new configuration information. If so, retain the original configuration according to the new configuration information; if not, continue to save according to the original configuration information; if the candidate cell identifier of the new configuration information contains a candidate cell identifier that was not originally saved, save according to the new configuration information; if the candidate cell identifier of the new configuration information does not contain the originally saved candidate cell, delete the configuration information corresponding to the candidate cell. Exemplarily, when the execution subject of S1101 is the source network device, referring to FIG12, in FIG12, the terminal device accesses the first serving cell when saving the pre-configuration information of CPAC (that is, the second serving cell and the first serving cell are the same cell), and the interaction process includes the following steps: S1201. RRC recovery request message. The source network device receives an RRC recovery request message from the terminal device, where the RRC recovery request message carries first information, and the first information includes: a terminal device identifier and / or a candidate cell identifier. S1202: Obtain CPAC pre-configuration information. The source network device obtains the corresponding CPAC pre-configuration information locally (source network device) based on the terminal device identifier and / or the candidate cell identifier. S1203: First request message. The source network device sends a first request message to other network devices corresponding to the candidate cell, where the first request message is used to instruct the other network devices to determine valid information of the configuration information of the candidate cell; and then obtains the valid information sent by the other network devices. In Figure 12 , the other network devices are network devices corresponding to the candidate cells in the CPAC pre-configuration information. The source network device sends a first request message to the other network devices, requesting the other network devices to determine valid information about the candidate cells. The valid information includes at least one of the following: the cell identifiers of candidate cells for which configuration information is valid, the cell identifiers of candidate cells for which configuration information is unavailable, and the cell identifiers of candidate cells for which configuration information needs to be updated. S1204: First response message. The source network device receives a first response message sent by other network devices, where the first response message carries valid information. S1205: Determine the processing method. First, the source network device updates the CPAC's pre-configuration information based on the valid information to obtain updated CPAC's pre-configuration information. Specifically, if the valid information indicates that the candidate cell's configuration information is unavailable, the candidate cell's configuration information in the CPAC's pre-configuration information is deleted; if the valid information indicates that the candidate cell's configuration information is valid, the candidate cell's configuration information in the CPAC's pre-configuration information is retained; if the valid information indicates that the candidate cell's configuration information needs to be updated, the candidate cell's configuration information in the CPAC's pre-configuration information is retained or deleted. In addition, the source network device also obtains the resource usage of the second service cell and the neighboring cells of the second service cell, where the second service cell is the cell currently accessed by the terminal device; obtains the measurement report carried by the wireless resource control recovery request message; and determines the processing method of the CPAC pre-configuration information based on the resource usage, measurement report and whether the terminal device is a dual-connection scenario. S1206, RRC recovery message. Then, the source network device sends an RRC recovery message to the terminal device, where the RRC recovery message carries second information, and the second information is used to indicate how the terminal device processes the pre-configuration information of the CPAC. In FIG12 , the source network device and the terminal device interact with each other, and the source network device updates the pre-configuration information of the CPAC and determines the processing method of the pre-configuration information of the CPAC. In another exemplary embodiment, when the execution subject of S1101 is the target network device, referring to FIG. 13 , the following steps are included: S1301. RRC recovery request message. The target network device receives an RRC recovery request message from the terminal device, where the RRC recovery request message carries first information, and the first information includes: a terminal device identifier and / or a candidate cell identifier. S1302: UE context request message. Among them, the target network device determines the source network device based on the terminal device identifier and / or the candidate cell identifier, and then sends a UE context request message to the source network device. The UE context request message carries indication information, which is used to instruct the source network device to obtain the pre-configuration information of CPAC. The indication information includes the terminal device identifier and / or the candidate cell identifier. S1303: Retrieve CPAC pre-configuration information.

This validity information includes the validity of the candidate cell's configuration information and whether it needs to be updated. Furthermore, the candidate cell's configuration information is the portion of the CPAC's pre-configured information related to the candidate cell.

In an embodiment of the present application, if the configuration information of each candidate cell in the pre-configuration information of the CPAC is valid, it is determined that the pre-configuration information of the CPAC is valid and does not need to be updated.
