DETAILED DESCRIPTION The technical solution in the present application will be described below in conjunction with the accompanying drawings. For ease of understanding, the following first introduces a communication scenario applicable to the embodiment of the present application in conjunction with FIG1 . The method provided in the embodiment of the present application can be used for various dual-connection multi-standard dual-connection (multiple RAT dual connectivity, MR-DC) architectures. For example, dual connection between a fourth generation (4G) communication system and a fifth generation (5G) communication system, dual connection between a 5G communication system and a 4G communication system, or dual connection between a 5G communication system and a 5G communication system, etc. The dual connectivity between the 4G communication system and the 5G communication system may include: Evolved universal terrestrial radio access (E-UTRA) system and new radio (NR) system dual connectivity (E-UTRA-NR dual connectivity, EN-DC), and NG-RAN E-UTRA-NR dual connectivity (NGEN-DC) under the 5G core network. EN-DC can also be called option 3 series. EN-DC is based on long term evolution (LTE) base stations. For example, eNB, as the master node (MN) or the main base station, uses an NR base station, such as gNB, as the DC of the secondary node (SN) or the secondary base station, and the MN and SN can respectively have data plane connections with the evolved packet core (EPC) network, that is, the 4G core network, to provide air interface transmission resources for data between the terminal and the EPC. NGEN-DC can also be called option 7 series. NG EN-DC uses an LTE base station, such as ng-eNB, as the MN, and an NR base station, such as gNB, as the DC of the SN. Unlike EN-DC, in NG EN-DC, both MN and SN are connected to the 5G core network (5G core network, 5GC), which provides air interface transmission resources for data between the terminal and the 5GC. The dual connectivity between the 5G communication system and the 4G communication system may include dual connectivity between the NR system and the E-UTRA system (NRE-UTRA dual connectivity, NE-DC), etc. NE-DC can also be referred to as option 4 series. NE-DC uses an NR base station, such as a gNB, as the MN and an LTE base station, such as an ng-eNB, as the SN, and the MN and SN can each have a data plane connection with the 5GC to provide air interface transmission resources for data between the terminal and the 5GC. The dual connection between the 5G communication system and the 5G communication system may include the DC between the NR system and the NR system. In the DC between the NR system and the NR system, both the MN and the SN are NR base stations. The following describes the method provided in the embodiment of the present application by taking the communication system 10 shown in FIG. 1 as an example. As shown in Figure 1, it is a schematic diagram of the architecture of a communication system 10 provided in an embodiment of the present application. In Figure 1, the communication system 10 may include a network device 101, a network device 102, a network device 105, a terminal device 103, and a terminal device 104. Figure 1 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in the present application. The network device in Figure 1, i.e., network device 101, network device 102 or network device 105, can be any device with a wireless transceiver process. Including but not limited to: evolutionary Node B (NodeB or eNB or e-NodeB) in LTE, base station (gNodeB or gNB) or transceiver point (transmission receiving point / transmission reception point, TRP) in NR, subsequent evolution of 3GPP, etc. The base station can be: a macro base station, a micro base station, a micro-micro base station, a small station, a relay station, or a balloon station, etc. Multiple base stations can support networks of the same technology mentioned above, or they can support networks of different technologies mentioned above. The base station can include one or more co-sited or non-co-sited TRPs. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The terminal in FIG1 , i.e., the terminal device 103 or the terminal device 104, is a device with a wireless transceiver process, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as a ship, etc.); it can also be deployed in the air (such as an airplane, a balloon, and a satellite, etc.). The terminal can be a mobile phone, a tablet computer (Pad), a computer with a wireless transceiver process, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a terminal in industrial control, a vehicle-mounted terminal device, a terminal in self-driving, a terminal in assisted driving, a terminal in remote medical care, a terminal in smart grid, a terminal in transportation safety, a terminal in smart city, a terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. A terminal may also be sometimes referred to as terminal equipment, user equipment (UE), access terminal, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal equipment, wireless communication equipment, machine terminal, UE agent or UE device, etc. A terminal may be fixed or mobile. As an example and not limitation, in the embodiments of the present application, the terminal may be a wearable device. Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that apply wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also powerful processes that are achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that have complete processes, large sizes, and can be implemented in whole or in part without relying on smartphones, such as smart watches or smart glasses, as well as devices that only focus on a certain type of application process and need to be used in conjunction with other devices such as smartphones, such as various types of smart bracelets and smart jewelry for vital sign monitoring. For ease of understanding, the communication process involved in the embodiments of the present application is introduced below. Traditional switching process Similar to the LTE system, the NR system supports the handover process for terminal devices in a connected state. When a terminal device that is using network services moves from one cell to another, or due to wireless transmission service load adjustment, activation operation maintenance, equipment failure, etc., in order to ensure the continuity of communication and the quality of service, the network equipment switches the communication link between the terminal device and the source cell (also known as the "source base station") to the new cell (also known as the "target cell or target base station"), that is, performs the handover process. For ease of understanding, the following describes a conventional switching process in conjunction with Figure 2. Referring to Figure 2, the method shown in Figure 2 includes steps S210 to S260. In step S210, the source network device triggers handover based on the L3 measurement result reported by the terminal device, and sends a handover request (HANDOVER REQUEST) to the target network device where the target cell is located through the Xn interface. In step S220, in response to the handover request, the target network device performs admission control. In step S230, the target network device sends a HANDOVER REQUEST ACKNOWLEDGE message to the source network device. In some implementations, the RRC configuration of the target cell may be included in the handover request confirmation. In step S240, the source network device sends an RRC reconfiguration message to the terminal device, instructing the terminal device to initiate a handover process. In some implementations, the RRC reconfiguration message includes RRC configuration information for accessing the target cell. In step S250, the terminal device accesses the target cell. In step S260, the terminal device sends an RRC Reconfiguration Complete message to the target network device. In some implementations, after the terminal device receives the switching instruction, the main behaviors of each protocol layer can be shown in Table 1. For the packet data convergence protocol (PDCP) layer, if the terminal device performs a switching operation based on the switching instruction, If the terminal device performs reconstruction, the terminal device needs to perform a security update. Correspondingly, if the terminal device recovers data at the PDCP layer based on the switching instruction, the terminal device does not need to perform a security update. For the radio link control (RLC) layer, if the terminal device is rebuilt based on the switching instruction, the terminal device may need to perform a security update, or may not need to perform a security update. For the media access control (MAC) layer, if the terminal device is rebuilt based on the switching instruction, the terminal device may need to perform a security update, or may not need to perform a security update. Table 1 It should be noted that in the embodiments of the present application, the content of the above security update is not specifically limited. For example, the security update may include updating the key. For another example, the security update may include updating the encryption algorithm. For another example, the security update may include updating the security algorithm. In addition, in the embodiment of the present application, the content of the above security update can be indicated by an RRC reconfiguration message. Of course, the content of the above security update can also be indicated by other means, which is not limited in the embodiment of the present application. It should also be noted that, in the embodiment of the present application, the operation of the protocol layer can be determined by the RRC reconfiguration message. For example, it can be determined by the RRC reconfiguration message whether to perform PDCP reconstruction. For another example, it can be determined by the RRC reconfiguration message whether to perform PDCP layer data recovery. For another example, it can be determined by the RRC reconfiguration message whether to perform RLC reconstruction. Of course, in the embodiment of the present application, the operation of the protocol layer can also be indicated by other means. It should also be noted that in the embodiment of the present application, the PDCP layer may be responsible for data-related security operations. For example, the PDCP layer may perform one or more of the following on the data: encryption at the AS layer, decryption at the AS layer, and integrity protection. Of course, in the embodiment of the present application, the PDCP layer may also perform other operations. Conditional PSCell addition / change (CPAC) process For ease of understanding, the CPAC process is introduced below in conjunction with Figure 1. In Figure 1, the terminal device 103 or the terminal device 104 can be dual-connected with the network device 101 and the network device 102, wherein one network device is the MN and the other network device is the SN. One or more service cells in the MN belong to a master cell group (MCG). Typically, the MCG may include a primary cell (PCell). In some implementations, the MCG may include one or more secondary cells (SCell) in addition to the PCell. One or more service cells in the SN belong to a secondary cell group (SCG). Typically, the SCG may include a primary secondary cell (PSCell). In some implementations, the SCG may include one or more SCells in addition to the PSCell. In the communication system 10 shown in Fig. 1, the terminal device 103 or the terminal device 104 can perform CPAC. For example, the terminal device 103 can perform conditional PSCell addition (CPA) through the following example 1 and conditional PSCell change (CPC) through the following example 2. Example 1, taking the case where the terminal device 103 establishes an RRC connection with the network device 101, and the terminal device 103 wants to perform CPA and establish a connection with the network device 102 as an example, after the network device 101 establishes an RRC connection with the terminal device 103, one or more candidate PSCells can be configured for the terminal device 103, and the one or more candidate PSCells include the PSCell configured by the network device 102 for the terminal device 103 and the PSCell configured by other network devices for the terminal device 103; the network device 101 sends the configuration information 1 of the one or more candidate PSCells to the terminal device 103, and the configuration information 1 of the candidate PSCell includes the configuration 1 of the candidate PSCell and the adding condition. The terminal device 103 receives the configuration information 1 of the one or more candidate PSCells from the network device 101, and can detect the adding condition of the one or more candidate PSCells. When at least one candidate PSCell that meets the adding condition is detected, the terminal device 103 selects one of the candidate PSCells (such as the candidate PSCell configured by the network device 102 for the terminal) and applies the configuration of the candidate PSCell. Subsequently, the terminal device 103 initiates random access with the candidate PSCell, and after the random access of the candidate PSCell is successful, establishes dual connections with the network device 101 and the network device 102. The configuration information 1 of the candidate PSCell may also be referred to as the CPA configuration information 1 of the candidate PSCell, and the embodiment of the present application does not limit the name of the configuration information. It is understandable that when the terminal device 103 detects multiple candidate PSCells that meet the adding conditions, it can select a candidate PSCell according to a preset strategy and apply the configuration of the candidate PSCell. For example, when the terminal device 103 detects multiple candidate PSCells that meet the adding conditions, it can randomly select a candidate PSCell and apply the configuration of the candidate PSCell; or, it can select the candidate PSCell with the best signal quality from the multiple candidate PSCells that meet the adding conditions, and apply the configuration of the candidate PSCell; or, it can select the candidate PSCell with the largest number of beams from the multiple candidate PSCells that meet the adding conditions and the number of beams is greater than or equal to the threshold value, and apply the configuration of the candidate PSCell. The above is only an example of the terminal device 103 selecting a candidate PSCell. The terminal device 103 can also select a candidate PSCell in other ways without limitation. Example 2: Terminal device 103 is dual-connected with network device 101 and network device 102. Network device 101 is MN. Taking SN 102 as an example, and the terminal device 103 wants to perform CPC, the network device 101 can configure one or more candidate PSCells for the terminal device 103; the network device 101 sends the configuration information 2 of the one or more candidate PSCells to the terminal device 103, and the configuration information 2 of the candidate PSCell includes the configuration 2 and the change condition of the candidate PSCell. The terminal device 103 receives the configuration information 2 of the one or more candidate PSCells from the network device 101, and can detect the change condition of the one or more candidate PSCells. When at least one candidate PSCell that meets the change condition is detected, the terminal device 103 selects one of the candidate PSCells and applies the configuration of the candidate PSCell. Subsequently, the terminal device 103 initiates random access with the candidate PSCell, and after the random access of the candidate PSCell is successful, a dual connection is established with the network device 101 and the secondary base station to which the candidate PSCell belongs. Among them, the configuration information 2 of the candidate PSCell can also be referred to as CPC configuration information 2 of the candidate PSCell, without limitation. It is understandable that when the terminal device 103 detects multiple candidate PSCells that meet the change conditions, it can select a candidate PSCell according to a preset strategy and apply the configuration of the candidate PSCell. For example, when the terminal device 103 detects multiple candidate PSCells that meet the change conditions, it can randomly select a candidate PSCell and apply the configuration of the candidate PSCell; or, it can select the candidate PSCell with the best signal quality from the multiple candidate PSCells that meet the change conditions, and apply the configuration of the candidate PSCell; or, it can select the candidate PSCell with the largest number of beams from the multiple candidate PSCells that meet the change conditions and the number of beams is greater than or equal to the threshold value, and apply the configuration of the candidate PSCell. The above is only an example of the terminal device 103 selecting a candidate PSCell. The terminal device 103 can also select a candidate PSCell in other ways without limitation. It should be noted that, in the embodiments of the present application, for any candidate PSCell among the one or more candidate PSCells configured by any network device for the terminal, when the terminal performs CPA, the configuration information 1 of the candidate PSCell, and when the terminal performs CPC, the configuration information 2 of the candidate PSCell can be collectively referred to as the configuration information of the candidate PSCell, and the configuration 1 of the candidate PSCell when the terminal performs CPA and the configuration 2 of the candidate PSCell when the terminal performs CPC can be collectively referred to as the configuration of the candidate PSCell. The configuration information of the candidate PSCell includes the configuration and addition / change conditions of the candidate PSCell. Among them, when the terminal performs CPA, the configuration of the candidate PSCell is used for the terminal to communicate with the candidate PSCell after adding the candidate PSCell, the addition / change conditions of the candidate PSCell include the addition conditions of the candidate PSCell, and the addition conditions of the candidate PSCell are used by the terminal to determine whether to add the candidate PSCell. When the terminal performs CPC, the configuration of the candidate PSCell is used for the terminal to communicate with the candidate PSC after changing the source PSCell to the candidate PSCell. The adding / changing conditions of the candidate PSCell include the changing conditions of the candidate PSCell. The changing conditions of the candidate PSCell are used by the terminal to determine whether to change the source PSCell to the candidate PSCell. When the terminal device 103 receives the configuration and adding / changing conditions of one or more candidate PSCells, but has not yet detected a PSCell that meets the adding / changing conditions, the terminal device 103 may also switch from the current MN to a target MN with better signal quality. For example, the terminal device 103 may switch from the network device 101 to the network device 105. Generally, after the terminal device 103 performs MN switching, the current MN releases one or more candidate PSCells configured for the terminal device 103. After the target MN establishes an RRC connection with the terminal device 103, one or more candidate PSCells may be reconfigured for the terminal device 103, and configuration information of one or more candidate PSCells configured by the target MN for the terminal is sent to the terminal device 103 for the terminal to perform CPAC. The configuration information of one or more candidate PSCells configured by the target MN for the terminal includes the configuration and adding / changing conditions of the candidate PSCell. Typically, the configuration and addition / change conditions of a candidate PSCell generally include more information, for example, the configuration of a candidate PSCell includes: an identifier of the configuration of the candidate PSCell, and / or, random access resources allocated by the candidate PSCell to the terminal, and / or, a cell radio network temporary identifier (CRNIT), and / or, a global cell identification code (CGI) of the candidate PSCell, and / or, a physical cell identifier (PCI) of the candidate PSCell, and / or, frequency information corresponding to the candidate PSCell. The frequency information corresponding to the candidate PSCell may include one or more of the following: the absolute frequency of the synchronization signal block (such as absoluteFrequency SSB), the absolute frequency position of the reference resource module (common RB0) (such as absoluteFrequencyPointA), a frequency bandwidth list (such as frequencyBandList), a subcarrier spacing (SCS) specific carrier list (such as scs-SpecificCarrierList), etc. The configuration of the candidate PSCell also includes resource information corresponding to the candidate PSCell, and the resource information corresponding to the candidate PSCell includes one or more of the following: bearer configuration parameters (radioBearerConfig), cell group configuration (cellGroupConfig) parameters, physical layer (physical layer, PHY layer) configuration parameters, media access control (media access control, MAC) layer configuration parameters, radio link control (radio link control, RLC) layer configuration parameters, packet data convergence layer protocol (packet data convergence protocol, PDCP) layer configuration parameters, service data adaptation protocol (service data adaptation protocol, SDAP) layer configuration parameters or RRC layer configuration parameters. The configuration of the candidate PSCell can also be referred to as the CPAC configuration of the candidate PSCell, the CPAC configuration information of the candidate PSCell, etc. The embodiments of the present application do not specifically limit the names of the above configurations. The adding / changing conditions of the candidate PSCell are used by the terminal to determine whether to add the candidate PSCell, or to determine whether to change the source PSCell to the candidate PSCell. For example, if the terminal detects that the candidate PSCell satisfies the adding / changing conditions of the candidate PSCell, the terminal determines to add the candidate PSCell, or to change the source PSCell to the candidate PSCell. If the terminal detects that the candidate PSCell does not satisfy the adding / changing conditions of the candidate PSCell, the terminal determines not to add the candidate PSCell, or not to change the source PSCell to the candidate PSCell. Optionally, the adding / changing condition of the candidate PSCell includes an execution event type of the adding / changing condition of the candidate PSCell, and the execution event type may also be referred to as a measurement event or a reporting event. The terminal may measure the signal quality of the candidate PSCell, or measure the The signal quality of the candidate PSCell and the signal quality of the neighboring cells of the candidate PSCell are measured, and according to the measurement results and the execution event type, it is determined whether to add the candidate PSCell, or whether to change the source PSCell to the candidate PSCell. Typically, before the terminal device executes the CPAC process described above, the network device provides the terminal device with a CPAC configuration, and accordingly, the terminal device changes the PSCell based on the CPAC configuration provided by the network device. In some implementations, the network device may determine whether the terminal device needs CPAC based on the service conditions (e.g., transmission delay, amount of data to be transmitted, etc.) and channel measurement conditions (e.g., channel status). In addition, in some implementations, the above-mentioned CPAC configuration may include a candidate cell configuration list, execution conditions, and cell configuration. The above candidate cell list can be understood as a candidate cell configuration list for CPA or CPC. The candidate cell list may include cell information of one or more candidate cells. The cell information of each candidate cell may include a configuration information identifier. It should be noted that the configuration information ID can be determined based on the number of candidate cells configured by the network device for the terminal device. For example, if the network device provides 5 candidate cell configurations for the terminal device, then the configuration information ID of the above cell can be used to identify the 5 candidate cell configurations. The above-mentioned execution condition may be an execution condition for instructing the terminal device to execute CPA or CPC. The above cell configuration may be provided by the candidate SN to the SCG configuration of the MN. In some implementations, the above SCG configuration may be sent by the SN to the MN via the Xn interface, and correspondingly, the MN transparently transmits it to the terminal device. In one implementation, the above SCG configuration may include the configuration of the candidate SCG, wherein the configuration of the candidate SCG may include the cell ID, radio bearer configuration, logical channel configuration, RLC configuration, MAC configuration, physical layer configuration, and SCell configuration. It should be noted that, as introduced above, an SCG may include one or more SCells. Accordingly, the above-mentioned SCG configuration may include one or more SCell configurations, which is not limited in the embodiments of the present application. Conditional handover (CHO) and CPAC combination process At present, some communication protocols (for example, R17) support carrying SCG configuration information in the CHO cell configuration so that the terminal device can quickly establish a dual link. Since the CHO cell is pre-configured, it may cause the failure of SCG addition to be triggered due to unreasonable SCG cell configuration. Therefore, in other communication protocols (for example, R10), a mechanism combining CHO and CPAC is introduced, also known as the "CHO+CPAC process", that is, the CHO cell can be associated with at least one CPAC cell, so that the terminal device can select the corresponding SCG based on the conditions and perform the addition, which helps to improve the situation of unreasonable SCG cell configuration. Selective activation of cell groups (SACG) process At present, in some communication protocols (for example, R16 and R17), the CPAC mechanism is introduced, that is, the network device can configure at least one candidate cell and the condition information associated with the cell for the terminal device (hereinafter referred to as "CAPC configuration"). Accordingly, after receiving the configuration, the terminal device can continuously evaluate the configured candidate cells. If at least one candidate cell meets the conditions, the terminal device triggers the CPAC process. After the terminal device completes the CPAC process, the terminal device can release all candidate cell configurations provided by the network device. As a result, the network device needs to configure the CPAC configuration for the terminal device before each terminal device executes the CAPC process, which greatly increases the overhead of transmitting the CPAC configuration. In some cases, the CPAC configuration can be reused. Therefore, in order to avoid frequent reconfiguration of the CPAC configuration by the network device, the CPAC process is enhanced in other communication protocols (for example, R10), that is, after completing a CPA or CPC process, the terminal device may not release the candidate cell configuration (that is, the CPAC configuration) and continue to evaluate the candidate cell to perform the next CPAC process. Therefore, the above SACG can also be called a "continuous CAPC process." CHO Reconstruction Enhancement In some communication protocols (e.g., R16), the CHO switching process is introduced to improve the robustness of the switching. Accordingly, the network device will pre-configure multiple sets of candidate cell configurations and condition information for the terminal device, and the terminal device can evaluate the candidate cells based on the condition information. If the switching conditions are met, the terminal device performs the switching process based on the candidate cell configuration. In some cases, if the CHO handover fails, the terminal device may trigger a connection reestablishment process. During the reestablishment process, the terminal device may first perform a cell reselection, and after the terminal device selects a candidate CHO cell, the terminal device may perform the CHO process again. In some implementations, the description of the above CHO reconstruction enhancement in the communication protocol may be as shown below: 1>If "attemptcondreconfig" is configured; and 1> If the selected cell is not configured with the event "CondEventT1", or the selected cell is configured with the event "CondEventT1" but the remaining conditions are not met; and 1> If the selected cell is one of the candidate cells corresponding to the synchronous reconfiguration "reconfigurationWithSync" contained in the primary cell group in the MCG variable "VarConditionalReconfig": 2> If the terminal device supports RLF-reporting for conditional switching, the CHO cell identity in the variable "VarRLF-Report" is set to the global cell identity, if available, based on the physical cell identity and the carrier frequency of the selected cell; 2> Apply the stored condRRCReconfig associated with the selected cell and perform the operations specified in Section 5.3.5.3. As described above, in some scenarios, the network device may configure CPAC candidate cells associated with the various processes described above for the terminal device, for example, the CPAC candidate cell configuration associated with the CHO+CPAC process (also known as the "first CPAC candidate cell configuration"). At least two of the CPAC configurations associated with the CPAC process (also known as the "second CPAC candidate cell configuration") and the CPAC candidate cell configuration associated with the SACG (also known as the "third CPAC candidate cell configuration"). The terminal device is unable to distinguish the processes associated with the acquired CPAC candidate cell configurations, resulting in easy confusion between the CPAC candidate cell configurations associated with multiple processes. Therefore, an embodiment of the present application provides a wireless communication method to distinguish the CPAC candidate cell configurations associated with the above-mentioned processes. For ease of understanding, the wireless communication method of the embodiment of the present application is introduced below in conjunction with Figure 3. The method shown in Figure 3 includes step S310. In step S310, the network device sends first candidate cell configuration information to the terminal device. In some implementations, the first candidate cell configuration information includes one or more of the following: a first CPAC candidate cell configuration associated with the first CHO cell configuration, a second CPAC candidate cell configuration, and a third CPAC candidate cell configuration associated with the SACG. For the convenience of the following description, at least two of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration are collectively referred to as "multiple CPAC candidate cell configurations". In the embodiment of the present application, the name of the above CPAC candidate cell configuration is not specifically limited. For example, the above CPAC candidate cell configuration can also be called SCG configuration, candidate cell configuration, etc. In the embodiment of the present application, the above-mentioned first candidate cell configuration information may be one or more of a full configuration, a reference configuration, and an incremental configuration. Among them, the reference configuration may be, for example, a configuration of a network device for a terminal device. Of course, the reference configuration may also be a configuration sent by a service network device that is autonomously retained by the terminal device, and the embodiment of the present application does not limit this. In some implementations, the terminal device may determine the candidate cell configuration based on the reference configuration and the incremental configuration. Of course, the terminal device may also determine the candidate cell configuration in other ways. In order to facilitate the distinction between the above-mentioned multiple CPAC candidate cell configurations, the embodiments of the present application respectively provide for the storage method of the CPAC candidate cell configuration, the transmission method of the CPAC candidate cell configuration, and the effective time of the CPAC candidate cell configuration, etc., which helps the terminal device to distinguish between multiple CPAC candidate cell configurations, and are introduced below in combination with implementation methods 1 to 3 respectively. It should be noted that implementation methods 1 to 3 of the embodiment of the present application can be used in combination with each other or used separately, and the embodiment of the present application is not limited to this. In addition, it should be noted that in the embodiments of the present application, multiple CPAC candidate cell configurations can also be distinguished based on other methods. For example, multiple CPAC candidate cell configurations can be distinguished based on the implementation of the terminal device. For another example, the implementation of the network device can be used to help the terminal device distinguish multiple CPAC candidate cell configurations. The embodiments of the present application are not limited to this. In implementation mode 1, at least two of the multiple CPAC candidate cell configurations have different transmission modes. Accordingly, the terminal device can distinguish the multiple CPAC candidate cell configurations based on different transmission modes. In other words, at least two of the transmission modes in the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration are different. For example, the transmission mode of the first CPAC candidate cell configuration is different from the transmission mode of the second CPAC candidate cell configuration. For another example, the transmission mode of the second CPAC candidate cell configuration is different from the transmission mode of the third CPAC candidate cell configuration. For another example, the transmission mode of the first CPAC candidate cell configuration is different from the transmission mode of the third CPAC candidate cell configuration. Of course, in an embodiment of the present application, the transmission modes of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration may all be different. In some implementations, the above different transmission modes can be understood as different information used to transmit multiple CPAC candidate cell configurations. Accordingly, the terminal device can distinguish multiple CPAC candidate cell configurations based on different information. Assume that the information of the first CPAC candidate cell configuration is the first information, the information of the second CPAC candidate cell configuration is the second information, and the information of the third CPAC candidate cell configuration is the third information. Then the above different transmission modes can be understood as at least two of the first information, the second information and the third information being different information. It should be noted that, in the embodiment of the present application, the first information, the second information and the third information can be understood as information transmitted independently. For example, the first information, the second information and the third information can correspond to different signaling. In other implementations, the above-mentioned different transmission modes may include transmitting the information used for the multiple CPAC candidate cell configurations as different information elements IE. Accordingly, the terminal device may distinguish the multiple CPAC candidate cell configurations based on different IEs (e.g., IE names). Assume that the information for transmitting the configuration of the first CPAC candidate cell is the first information, the information for transmitting the configuration of the second CPAC candidate cell is the second information, and the information for transmitting the configuration of the third CPAC candidate cell is the third information. Then the above different transmission modes can be understood as at least two of the first information, the second information, and the third information being different IEs. It should be noted that, in the embodiment of the present application, the IEs used to carry multiple CPAC candidate cell configurations may be different IEs in the same signaling. Of course, the IEs used to carry multiple CPAC candidate cell configurations may be different IEs in different signaling. In other implementations, the above-mentioned different transmission methods may include different information nesting methods corresponding to the information of transmitting multiple CPAC candidate cell configurations. For example, the first CPAC candidate cell configuration may be delivered in a nested manner with the first CHO cell configuration, that is, the first CHO cell configuration may be nested with the first CPAC candidate cell configuration. In this way, when the terminal device determines that the CPAC candidate cell configuration is nested in the first CHO cell configuration, the terminal device can determine that the CPAC candidate cell configuration is the first CPAC candidate cell configuration, that is, associated with the CHO+CPAC process. When the terminal device receives a CPAC candidate cell configuration transmitted in an information nesting manner, the terminal device can determine that the CPAC candidate cell configuration is the second CPAC candidate cell configuration. It should be noted that in an embodiment of the present application, the first CPAC candidate cell configuration can be issued in a nested manner with the first CHO cell configuration. Of course, the first CPAC candidate cell configuration can also be issued in a parallel manner with the first CHO cell configuration. For example, the configuration of the CHO+CPAC process can include the first CPAC candidate cell configuration and the first CHO cell configuration. In other implementations, the above-mentioned different transmission modes may include indicating the process associated with the CPAC candidate cell configuration through indication information. In other words, indicating that the CPAC candidate cell configuration is one of multiple CPAC candidate cell configurations through indication information. For example, the first candidate cell configuration information carries first indication information, and the first indication information is used to indicate that the first candidate cell configuration information is one of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration and the third CPAC candidate cell configuration. It should be noted that, in the embodiment of the present application, the above indication information can be transmitted simultaneously with the CPAC candidate cell configuration. For example, the first indication information can be transmitted simultaneously with the first CPAC candidate cell configuration. Of course, in the embodiment of the present application, the indication information can be transmitted separately from the CPAC candidate cell configuration. In addition, in the embodiment of the present application, the configuration granularity of the above-mentioned indication information is not limited. In some implementations, the configuration granularity of the indication information is uniformly configured for the candidate cell list. At this time, it can be understood that the indication information indicates the process corresponding to the CPAC candidate cell configuration associated with the entire candidate cell list. In other implementations, the configuration granularity of the indication information may be for a set of candidate cells in the candidate cell list. For example, the candidate cells in the first candidate cell set may be associated with the CHO+CPAC process, the candidate cells in the second candidate cell set may be associated with the CPAC process, and the candidate cells in the third candidate cell set may be associated with the SACG process. Accordingly, the configuration granularity of the indication information may be the candidate cell set. That is, the first candidate cell set corresponds to indication information 1 for indicating the CHO+CPAC process, the second candidate cell set corresponds to indication information 2 for indicating the CPAC process, and the third candidate cell set corresponds to indication information 3 for indicating the SACG process. Of course, in the embodiment of the present application, the configuration granularity of the indication information may also be a separate indication of the candidate cell configuration corresponding to each candidate cell. In implementation mode 2, the effective time of multiple CPAC candidate cell configurations is different, or in other words, multiple CPAC candidate cell configurations are not effective at the same time. Accordingly, since one of the multiple CPAC candidate cell configurations is effective within a period of time, the terminal device does not need to distinguish between multiple CPAC candidate cell configurations. In other words, the effective time of at least two of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration is different. For example, the effective time of the first CPAC candidate cell configuration is different from the effective time of the second CPAC candidate cell configuration. For another example, the effective time of the second CPAC candidate cell configuration is different from the effective time of the third CPAC candidate cell configuration. For another example, the effective time of the first CPAC candidate cell configuration is different from the effective time of the third CPAC candidate cell configuration. Of course, in an embodiment of the present application, the effective times of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration may all be different. In other words, the processes associated with the configuration of multiple CPAC candidate cells do not take effect at the same time. In other words, at least two of the SACG process, CAPC process, and CHO+CPAC process do not take effect at the same time. In other words, the terminal device cannot support more than one process to be configured at the same time. In other words, the network device will not configure at least two processes for the terminal device at the same time. For example, the CAPC process and the SACG process are not configured at the same time. In this case, the second CAPC candidate cell configuration and the third CAPC candidate cell configuration are not effective at the same time. For another example, if the terminal device is configured with the SACG process, the first CAPC candidate cell configuration cannot be included in the CHO cell configuration, that is, the terminal device does not support the CHO+CPAC process. For another example, if the terminal device is configured with the CAPC process, the first CAPC candidate cell configuration cannot be included in the CHO cell configuration, that is, the terminal device does not support the CHO+CPAC process. In some implementations, at least two of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration may be defined in a predefined manner (e.g., protocol predefined) so that they are not effective at the same time. Of course, in the embodiment of the present application, the network device can also configure the terminal device with at least two of the above processes at the same time, or in other words, the above at least two processes can be effective at the same time, but each process may not involve the same candidate cell, that is, a candidate cell can only support one process. For example, for the terminal device, a first CPAC candidate cell configuration and a third CPAC candidate cell configuration can be configured at the same time, wherein the first CPAC candidate cell configuration can be associated with CPAC candidate cell 1, and the third CPAC candidate cell configuration can be associated with CPAC candidate cell 2, wherein CPAC candidate cell 1 is different from CPAC candidate cell 2. In implementation mode 3, at least two of the multiple CPAC candidate cell configurations are stored in different ways. Accordingly, the terminal device can distinguish the multiple CPAC candidate cell configurations based on different transmission modes. In other words, at least two of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration are stored in different ways. The storage method is different. For another example, the storage method of the second CPAC candidate cell configuration is different from the storage method of the third CPAC candidate cell configuration. For another example, the storage method of the first CPAC candidate cell configuration is different from the storage method of the third CPAC candidate cell configuration. Of course, in the embodiment of the present application, the storage methods of the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration may all be different. In some implementations, the above storage methods may include storing multiple CPAC candidate cell configurations in different variables, wherein different variables may correspond to different variable names, for example. Assume that the storage variable corresponding to the first CPAC candidate cell configuration is a first variable, the storage variable corresponding to the second CPAC candidate cell configuration is a second variable, and the storage variable corresponding to the third CPAC candidate cell configuration is a third variable. Accordingly, at least two of the first variable, the second variable, and the third variable are different variables. For example, the terminal device receives CPAC configuration information, and the CPAC configuration information is associated with the CAPC process. Accordingly, the terminal device stores the candidate cell configuration (ie, the second CAPC candidate cell configuration) in the CPAC configuration information in a second variable (represented by "VarConditionalReconfig"). If the terminal device supports both CHO+CPAC processes, when the terminal device receives the CPAC configuration associated with the CHO+CPAC process, it will also store the CPAC candidate cell configuration (ie, the first CAPC candidate cell configuration) in the CPAC configuration in the first variable. If the terminal device supports the SACG process at the same time, after receiving the SACG configuration, the terminal device can store the CPAC candidate cell configuration (ie, the third CAPC candidate cell configuration) in the SACG configuration into the third variable. In some other implementations, at least two of the first variable, the second variable, and the third variable are different partitions of the same variable. For example, the second variable used to store the second CAPC candidate cell configuration can be expressed as "SCG VarConditionalReconfig", and the third variable used to store the third CAPC candidate cell configuration can be expressed as "SACG VarConditionalReconfig", where the second variable and the third variable can be understood as two categories in the variable "VarConditionalReconfig". The above introduces a scheme for a terminal device to distinguish between multiple CPAC candidate cell configurations in an embodiment of the present application. The following introduces the storage conditions of the first CPAC candidate cell configuration, or the storage method of the first CPAC candidate cell configuration, in an embodiment of the present application. In addition, in the embodiment of the present application, the storage condition of the first CPAC candidate cell configuration can be used in combination with the above-mentioned scheme for distinguishing multiple CPAC candidate cell configurations. Of course, the storage condition of the first CPAC candidate cell configuration can be used alone with the above-mentioned scheme for distinguishing multiple CPAC candidate cell configurations. For the first CPAC candidate cell configuration, in some implementations, the above-mentioned storage condition may include the terminal device determining the first CHO cell associated with the first CHO cell configuration based on conditional switching. That is to say, if the first candidate cell configuration information includes the first CPAC candidate cell configuration, the above method also includes: if the terminal device determines the first CHO cell based on conditional switching (for example, the switching condition in the first CHO cell configuration), the first terminal device stores the first CPAC candidate cell configuration in the first variable. In some other implementations, the above storage conditions may also include that the terminal device determines the first CHO cell based on the conditional switching, and the terminal device uses the first CHO cell configuration. Of course, in the embodiment of the present application, the above storage conditions may also include that the terminal device successfully performs CHO based on the first CHO cell configuration. Of course, in the embodiment of the present application, when the terminal device receives the CHO+CPAC configuration, it can immediately store the first CHO cell configuration and the first CPAC candidate cell configuration in the CHO+CPAC configuration. It should be noted that in the embodiment of the present application, there is no specific limitation on the situation where the terminal device uses the first CHO cell configuration. For example, the terminal device can use the first CHO cell configuration when the conditions of the first CHO cell are met. For another example, the terminal device uses the first CHO cell configuration when it needs to use the candidate cell configuration of the first CHO cell. For another example, the terminal device can use the first CHO cell configuration when executing the reconfiguration process. As introduced above, in some scenarios, the first CPAC candidate cell configuration can be nested in the first CHO cell configuration. Accordingly, when storing the first CPAC candidate cell configuration, the terminal device can first store the first CHO cell configuration in an associated variable (for example, the fourth variable is represented by "VarConditionalReconfig"), and then store the first CPAC candidate cell configuration in the first variable. Of course, in an embodiment of the present application, the first CPAC candidate cell configuration is not nested in the first CHO cell configuration, then the terminal device can also store the first CHO cell configuration and the first CPAC candidate cell configuration in different variables at the same time, and the embodiment of the present application is not limited to this. For ease of understanding, the following describes the combination of storage conditions and storage methods in the embodiments of the present application in conjunction with Examples 1 to 3. It should be noted that Examples 1 to 3 are described by taking the first CHO cell configuration including the first CPAC candidate cell configuration as an example, and Examples 1 to 3 can also be applied to the scenario where the first CHO cell configuration and the first CPAC candidate cell configuration are transmitted in a non-nested manner, and the embodiments of the present application are not limited to this. Example 1: Assuming that the terminal device supports the CHO+CPAC process, the network device can send a first CHO cell configuration to the terminal device, and the first CHO cell configuration includes a first CPAC candidate cell configuration. Accordingly, the terminal device can store the first CHO cell configuration in the variable "VarConditionalReconfig". If the terminal device determines the first CHO cell based on the condition and applies the first CHO cell configuration information, the terminal device can write the first CPAC candidate cell configuration nested in the first CHO cell configuration into the first variable. Example 2: Assuming that the terminal device supports the CHO+CPAC process, the network device can send a first CHO cell configuration to the terminal device, and the first CHO cell configuration includes a first CPAC candidate cell configuration. If the CHO is successful, the terminal device can apply the conditions in the first CHO cell configuration to perform reconfiguration, and store the first CPAC candidate cell configuration carried in the first CHO cell configuration in the variable "VarConditionalReconfig for SCG" used to store SCG. Example 3: Assuming that the terminal device supports the CHO+CPAC process, the network device can send a first CHO cell configuration to the terminal device, and the first CHO cell configuration includes a first CPAC candidate cell configuration. If the CHO execution condition of the first CHO cell is met, the terminal device can store the first CPAC candidate cell configuration carried in the first CHO cell configuration into the variable "VarConditionalReconfig for SCG" used to store SCG. The above describes the storage conditions of the first CPAC candidate cell configuration, and the following describes the release conditions of various CPAC candidate cell configurations in the embodiment of the present application. For ease of understanding, the following describes various CPAC candidate cell configurations in combination with scenarios 1 to 3. Scenario 1: Release conditions configured for the first CPAC candidate cell. According to the existing protocol, if the terminal device successfully executes CHO, the terminal device will release all conditional reconfiguration variables, including the MCG configuration stored in the variable "MCG VarConditionalReconfig" and the SCG configuration stored in the variable "SCG VarConditionalReconfig". In other words, the CPAC configuration associated with the CHO cell will also be released, but at this time, the terminal device often needs to continue to perform the SCG conditional evaluation. If the CPAC configuration associated with the CHO cell is released, the terminal device will not be able to perform SCG addition or modification based on the CPAC configuration. Therefore, in an embodiment of the present application, if the terminal device accesses the first CHO cell, the terminal device releases other cell configurations except the first CPAC candidate cell configuration. In some implementations, the terminal device accessing the first CHO cell may include, for example, the terminal device randomly accessing the first CHO cell successfully. It should be noted that in the embodiment of the present application, other cell configurations may include one or more of the first CHO cell configuration (e.g., MCG-associated configuration), the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration. Of course, in the embodiment of the present application, other cell configurations may also include candidate cell configurations that have been executed / applied. To facilitate understanding, the following takes the synchronous reconfiguration (expressed as "reconfigurationWithSync") included in the first CPAC candidate cell configuration as an example, combined with the description of the communication protocol, to introduce the release conditions of the first CPAC candidate cell configuration in an embodiment of the present application. 1> If reconfigurationWithSync is contained in the variable "spCellConfig" of the MCG or SCG, and when the MAC of the NR cell group successfully completes the triggered random access procedure; 2> If the reconfigurationWithSync contained in the variable spCellConfig of MCG is not configured by the CHO+CPAC process; 2> If reconfigurationWithSync is included in the spCellConfig of SCG, and CPA or CPC is not configured by CHO+CPAC process: 3> Delete all configurations except the CHO+CPAC process configuration contained in the spCellConfig of MCG or SCG, if any; 3>Based on TS 36.331

[0010] ,Description of clause 5.3.5.9.6, delete the configuration stored in the variable "VarConditionalReconfiguration", if any; In other scenarios, when the terminal device successfully executes CHO for the first CHO cell, the terminal device may also release the first CPAC candidate cell configuration. For example, when the terminal device completes the CHO and CPAC process associated with the first CPAC candidate cell configuration, the terminal device may no longer need to use the first CPAC candidate cell configuration. Therefore, the terminal device may release the first CPAC candidate cell configuration to save storage space. For another example, when the terminal device releases the SCG associated with the first CPAC candidate cell configuration, the terminal device may release the first CPAC candidate cell configuration. It should be noted that, when the terminal device successfully performs CHO for the first CHO cell, other CHO cell configurations and CPAC candidate cell configurations associated with other CHO cell configurations may also be released. The above describes the release conditions configured for the first CPAC candidate cell if the CHO performed by the terminal device on the first CHO cell is successful in an embodiment of the present application. The following describes the release conditions configured for the first CAPC candidate cell if the CHO performed by the terminal device on the first CHO cell fails in an embodiment of the present application. In other scenarios, the terminal device will trigger RRC connection re-establishment after the CHO execution fails. According to the provisions of the existing communication protocol, if the terminal device reselects a CHO cell, the terminal device will not release the content in the variable "VarConditionalReconfig". But in fact, if the terminal device CHO is successful, the terminal device only needs to evaluate the CPAC candidate cell associated with the CHO cell where the CHO is successful. As for the first CPAC candidate cell configuration associated with the first CHO cell where the CHO failed, even if it is stored in the variable "VarConditionalReconfig", the terminal device will no longer use it, resulting in a waste of storage space. Therefore, in order to save storage space, in the embodiment of the present application, when the CHO performed by the terminal device on the first CHO cell fails, The terminal device can clear the first CAPC candidate cell configuration associated with the first CHO cell configuration. In other words, when the terminal device CHO succeeds, the terminal device can clear the CAPC candidate cell configuration associated with the CHO cell where the CHO failed before. The variable "VarConditionalReconfig for SCG" is used to store the CPAC candidate cell configuration associated with the cell where the terminal device failed CHO before. Taking the first candidate cell configuration information including the first CPAC candidate cell configuration as an example, the above method also includes: if the first condition is met, the terminal device releases the first CPAC candidate cell configuration. In some implementations, the first condition includes one or more of the following: the terminal device enters an idle state; the terminal device enters an inactive state; the timer T304 of the terminal device times out; the terminal device receives an RRC release message; the terminal device fails to switch the first CHO cell based on the condition; the terminal device selects a cell other than the first CHO cell during the operation of timer T311. Taking the first condition including the terminal device entering the idle state as an example, when the terminal device enters the idle state, it can be understood that the terminal device fails to execute CHO for the first CHO cell, and the terminal device can release the first CAPC candidate cell configuration. Taking the first condition including the terminal device entering the inactive state as an example, when the terminal device enters the inactive state, it can be understood that the terminal device fails to execute CHO for the first CHO cell, and the terminal device can release the first CAPC candidate cell configuration. Taking the first condition including the timer T304 of the terminal device timing out as an example, when the timer T304 times out, the switching of the terminal device in LTE FDD fails, and accordingly, the terminal device can release the first CAPC candidate cell configuration. Taking the first condition including the terminal device receiving an RRC release message as an example, when the terminal device receives the RRC release message sent by the network device, the terminal device may release the first CAPC candidate cell configuration. Taking the example that the first condition includes the terminal device failing to switch the first CHO cell based on the condition, when the terminal device fails in CHO for the first CHO cell, the terminal device may release the first CAPC candidate cell configuration. Taking the first condition including that the terminal device selects a cell other than the first CHO cell during the operation of timer T311 as an example, generally, when the terminal device initiates the initial RRC connection reestablishment, timer T311 can be started. Accordingly, when the terminal device selects a suitable cell (e.g., an E-UTRAN cell or an inter-RAT cell), the terminal device can stop timer T311. Therefore, during the running of timer T311, the terminal device selects a cell other than the first CHO cell, indicating that the terminal device finds another suitable cell to access. The first CHO cell can be understood as the cell where the terminal device fails to perform CHO. At this time, the terminal device can release the first CAPC candidate cell configuration. Scenario 2: Release conditions configured for the third CPAC candidate cell. At present, the existing communication protocol stipulates that after the terminal device receives the candidate cell configuration (i.e., the third CAPC candidate cell configuration) of the SACG process, it will also store it in a variable, and when the terminal device executes CPA or CPC successfully, the terminal device will immediately release the third CAPC candidate cell configuration. However, since the SACG process is a continuous CPAC process, that is to say, even if the terminal device successfully performs CPA or CPC based on the third CAPC candidate cell configuration, the terminal device still needs to continue to perform the next round of CPA or CPC based on the third CAPC candidate cell configuration. The release mechanism of the third CAPC candidate cell configuration specified in the current communication protocol will cause the terminal device to be unable to perform the next round of CPA or CPC. Therefore, the embodiment of the present application provides a solution for releasing the candidate cell configuration. That is, if the terminal device successfully performs CPA or CPC based on the third CPAC candidate cell configuration, the terminal device releases other cell configurations except the third CPAC candidate cell configuration. It should be noted that the above-mentioned other cell configurations may include one or more of the first CHO cell configuration (e.g., MCG-associated configuration), the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration. Of course, in the embodiment of the present application, the other cell configurations may also include candidate cell configurations that have been executed / applied. To facilitate understanding, the following takes the synchronous reconfiguration (expressed as "reconfigurationWithSync") included in the third CPAC candidate cell configuration as an example, combined with the description of the communication protocol, to introduce the release conditions of the third CPAC candidate cell configuration in an embodiment of the present application. 1> If reconfigurationWithSync is contained in the variable "spCellConfig" of the MCG or SCG, and when the MAC of the NR cell group successfully completes the triggered random access procedure; 2>If reconfigurationWithSync is contained in the variable spCellConfig in MCG; 2> If reconfigurationWithSync is included in the spCellConfig of SCG, and CPA or CPC is not configured by the SACG process: 3> Delete other configurations contained in the spCellConfig of MCG or SCG except the configuration of the SACG process configuration, if any; 3> Based on the description in TS 36.331

[0010] , clause 5.3.5.9.6, delete the configuration stored in the variable "VarConditionalReconfiguration", if any; Scenario 3: The release conditions provided by the embodiment of the present application are for the case where the first CPAC candidate cell configuration, the second CPAC candidate cell configuration, and the third CPAC candidate cell configuration are configured at the same time. If the network device configures the CHO+CPAC process for the terminal device, after receiving the CHO+CPAC configuration, the terminal device will store the configuration of the candidate cell (including the CHO cell and CPAC) in the variable "VarConditionalReconfig". If the device is configured with the CPAC process or the SACG process, the candidate cell configuration associated with the CPAC process and the candidate cell configuration associated with the SACG process may also be stored in the variable "VarConditionalReconfig". If the terminal device fails to attempt CHO access, triggering the reconstruction process and selecting a CHO cell (for example, the first CHO cell), the terminal device will release the configurations of both MCG and SCG in the variable "VarConditionalReconfig" in accordance with the provisions of the existing protocol. In the CHO+CPAC process, the terminal device will continue to execute the CPAC process associated with the first CHO cell, that is, the terminal device also needs to execute the CPAC process based on the first CPAC candidate cell configuration. According to the release mechanism specified in the existing protocol, the terminal device will not be able to execute the CPAC process based on the first CPAC candidate cell configuration. During the SACG process, the terminal device also needs to continue to perform the SACG process based on the third CPAC candidate cell configuration. According to the release mechanism specified in the existing protocol, the terminal device will also release the third CPAC candidate cell configuration, resulting in the terminal device being unable to perform the SACG process based on the third CPAC candidate cell configuration. Therefore, in response to the above problem, an embodiment of the present application provides a release mechanism, that is, the above method also includes: if the terminal device accesses the first CHO cell, the terminal device releases other cell configurations except the first CPAC candidate cell configuration and the third CPAC candidate cell configuration. It should be noted that the above other cell configurations may include a first CHO cell configuration (eg, MCG-associated configuration) and / or a second CPAC candidate cell configuration. Of course, in the embodiment of the present application, other cell configurations may also include candidate cell configurations that have been executed and / or applied. For ease of understanding, the release scheme in the embodiment of the present application is introduced below in conjunction with Figure 4. As shown in Figure 4, the variables in the terminal device include the MCG variable "MCG var" and the SCG variable "SCG var".
