[0028] This article introduces Multi-Radio Dual Connectivity (MR-DC).

[0029] MR-DC is a generalized Evolved-Universal Terrestrial Radio Access (E-UTRA) intra-E-UTRA dual connectivity. In some embodiments, based on MR-DC, a terminal can utilize radio resources provided by two different schedules located at two different Next Generation Radio Access Network (NG-RAN) nodes, one providing NR access and the other providing E-UTRA or NR access via a non-ideal backhaul connection. One serves as a Master Node (MN) and the other as a Secondary Node (SN). The MN and SN are connected via a network interface, and at least the MN is connected to a core network.

[0030] (1) MR-DC based on the Evolved Packet Core (EPC) network (MR-DC with EPC) Illustratively, FIG. 1 is a schematic diagram of a system architecture of MR-DC based on EPC provided by an exemplary embodiment of the present application. As shown in FIG. 1, an Evolved-Universal Terrestrial Radio Access Network (E-UTRAN) supports MR-DC via E-UTRA and NR dual connectivity (E-UTRA-NR dual connectivity (EN-DC)). A terminal is connected to an eNB functioning as a mobile node (MN) and an en-gNB functioning as an SN (SN). The eNB is connected to the EPC via an S1 interface and to the en-gNB via an X2 interface. The en-gNB may be connected to the EPC via an S1-U interface and to other en-gNBs via an X2-U interface. In some embodiments, the EPC of a Long Term Evolution (LTE) system may include a mobility management entity (MME), a serving gateway (S-GW), etc.

[0031] It should be noted that the number of communication devices in the system shown in Figure 1 is merely an example, and the number of communication devices may be greater, and the connection relationships may also be changed according to actual circumstances. The example of Figure 1 does not limit the system architecture provided by the embodiments of the present application.

[0032] (2) MR-DC based on the 5G core network (5G Core, 5GC) (MR-DC with 5GC) Illustratively, Figure 2 is a schematic diagram of the system architecture of MR-DC based on 5GC provided by an exemplary embodiment of the present application. As shown in Figure 2, MR-DC based on 5GC can be divided into the following three cases:

[0033] A) E-UTRA and NR Dual Connectivity (E-UTRA-NR Dual Connectivity, EN-DC) The NG-RAN supports NG-RAN E-UTRA-NR dual connectivity, also referred to in some embodiments as NGEN-DC. In this configuration, a terminal connects to one ng-eNB as a mobile node and one gNB as a system node. The ng-eNB is connected to the 5GC interface, and the gNB is connected to the ng-eNB via the Xn interface.

[0034] B) NR and E-UTRA Dual Connectivity (NR-E-UTRA Dual Connectivity, NE-DC) NG-RAN supports NR-E-UTRA dual connectivity, where the terminal connects to a gNB functioning as a mobile node and an ng-eNB functioning as a system node. The gNB is connected to 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0035] C) NR-NR Dual Connectivity (NR-DC) NG-RAN supports NR-NR dual connectivity, where a terminal connects to a gNB functioning as a mobile node and another gNB functioning as a system node (SN). The master gNB connects to 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB may connect to 5GC via the NG-U interface. NR-DC can also be used by a terminal to access a single gNB as both a mobile node and a system node (SN) and configure the MCG and SCG simultaneously.

[0036] In some embodiments, the 5GC of a 5G NR system may include an Access and Mobility Management Function (AMF), a User Plane Function (UPF), etc.

[0037] Note that the number of communication devices in the system shown in Figure 2 is merely an example, and the number of communication devices may be greater, and the connection relationships may also be changed according to actual circumstances. The example of Figure 2 does not limit the system architecture provided by the embodiments of the present application.

[0038] In dual connectivity, a terminal can access two cell groups. For example, FIG. 3 is a schematic diagram of cells in dual connectivity provided by an exemplary embodiment of the present application. As shown in FIG. 3, in some embodiments, the two cell groups in dual connectivity are a master cell group (MCG) and a secondary cell group (SCG), respectively. The MCG may contain multiple cells, one of which is used to initiate initial access. In some embodiments, this cell is called a primary cell (PCell). As the name suggests, the PCell is the most "main" cell in the MCG. The PCell in the MCG and the secondary cell (SCell) in the MCG are integrated by carrier aggregation (CA). The MCG includes the primary cell (PCell) and the secondary cell (SCell). In some embodiments, the SCG includes a primary secondary cell (PSCell) and the secondary cell (SCell). Since most signaling is transmitted only via PCell and PSCell, for convenience of explanation, the concept of a special cell (sPCell) is also defined in related communication protocols, and PCell and PSCell are collectively referred to as sPCell.

[0039] It should be noted that the number of cells in the dual connection shown in Figure 3 is merely an example, and the number of cells in the master cell group and the secondary cell group may be greater, and the connection relationship may also be changed according to actual circumstances. The example of Figure 3 does not limit the cells in the dual connection provided by the embodiments of the present application.

[0040] This section introduces Conditional Handover (CHO).

[0041] CHO refers to a handover that a terminal performs when one or more handover execution conditions are met. In some embodiments, the terminal starts evaluating the execution conditions after receiving a CHO configuration and stops evaluating the execution conditions after performing a handover (including legacy handover and CHO). In some embodiments, CHO applies to the following criteria: · The CHO setting includes the CHO candidate cell setting and execution conditions. One execution condition includes one or two trigger events (e.g., CHO events A3 / A5). If the UE receives a handover (HO) command that does not include a CHO setting before any CHO execution conditions are met, it performs the legacy handover (legacy HO) process regardless of any previously received CHO settings. When performing CHO, that is, from the point when the terminal starts synchronizing with the target cell, the terminal does not monitor the source cell.

[0042] Illustratively, the conditional event (CondEvent) A3 is a case where a conditional reconfiguration candidate (cell) has a better offset amount than a PCell / PSCell (Conditional reconfiguration candidate becomes an amount of offset better than a PCell / PSCell).

[0043] Exemplarily, conditional event (CondEvent) A5 is when the PCell / PSCell becomes worse than absolute threshold 1 and the conditional reconfiguration candidate (cell) becomes better than another absolute threshold 2 (PCell / PSCell becomes worse than absolute threshold 1 AND Conditional reconfiguration candidate becomes better than another absolute threshold 2).

[0044] This paper introduces Conditional Primary Secondary Cell Addition / Change (CPAC).

[0045] CPAC includes Conditional Primary Secondary Cell Addition (CPA) and Conditional Primary Secondary Cell Change (CPC).

[0046] CPA In some embodiments, a Conditional PSCell Addition (CPA) is defined as a PSCell addition that is executed by the UE when execution condition(s) is met. The UE starts evaluating the execution condition(s) upon receiving the CPA configuration and stops evaluating the execution condition(s) once PSCell addition or PCell change is triggered.

[0047] CPC In some embodiments, a CPC is defined as a PSCell change executed by a terminal when an execution condition is met. The terminal starts evaluating the execution condition upon receiving a CPC configuration and stops evaluating the execution condition upon triggering a PSCell change or a PCell change. Intra-SN CPC does not involve the MN, while inter-SN CPC supports initiation by the MN or SN. (A Conditional PSCell Change (CPC) is defined as a PSCell change that is executed by the UE when execution condition(s) is met. The UE starts evaluating the execution condition(s) upon receiving the CPC configuration and stops evaluating the execution condition(s) once a PSCell change or PCell change is triggered. Intra-SN CPC without MN involvement and inter-SN CPC initiated either by the MN or SN are supported.)

[0048] We introduce the joint setup of CHO and CPAC.

[0049] R16 (Release 16) / R17 (Release 17) introduces condition-triggered mobility management. In some embodiments, a terminal implements condition-triggered mobility management based on network-configured conditions and associated candidate cells. When the conditions are met, the terminal triggers mobility management and accesses the associated candidate cells. In some embodiments, the network-configured conditions may be specific events based on measurement results, or location- or time-based events. The associated candidate cells may be candidate primary or primary secondary cells that correspond to mobility management CHO and CPAC based on the corresponding condition triggers. Currently, R17 supports MN-initiated CHO, MN-initiated CPA / CPC, and SN-initiated CPC.

[0050] However, R16 / R17 does not support simultaneous configuration of CHO and CPA / CPC. To improve robustness and reduce the impact on terminal throughput, R18 (Release 18) is proposed to consider the combination of CHO and CPC / CPA, and it is decided that the target MCG and candidate SCG for CPC / CPA will be included in CHO. CHO and CPA / CPC are jointly configured, and the terminal can run CHO and its corresponding CPA / CPC simultaneously.

[0051] In the discussion on mobility in R18, in the joint configuration and strengthening scheme of CHO and CPA / CPC, CHO and CPAC may be launched by the same node or different nodes. Currently, it is widely believed that CHO should be launched by the source master node (Source MN, S-MN), but there are various views on the launch node of CPA / CPC, mainly including: CPA / CPC initiated by S-MN (execution conditions are determined by S-MN) CPA / CPC initiated by the Target Master Node (Target MN, T-MN) (execution conditions are determined by the T-MN) CPA / CPC initiated by the Source Secondary Node (Source SN, S-SN) (the execution conditions are determined by the S-SN) Since the candidate SCG corresponding to the CPA / CPC needs to be associated with the candidate MCG corresponding to the CHO, the main consideration is that the CPC / CPA is activated by the T-MN and the conditions of the CPA / CPC are also set by the T-MN.

[0052] We introduce selective activation of cell groups (CGs).

[0053] In R16 CHO and R17 CPA / CPC, a UE configured with CHO / CPC / CPA must release the CHO / CPC / CPA configuration upon completing random access to the target PCell / PSCell. Therefore, if the network does not reconfigure and reinitialize the CHO / CPC / CPA, the UE loses the opportunity to continue with the CHO / CPC / CPA. This increases the delay in handover or SCG change and increases signaling overhead, especially when the CG is changed frequently in Frequency Range 2 (FR2) scenarios.

[0054] Therefore, the R18 mobility enhancement proposes selective activation of cell groups in MR-DC. In some embodiments, selective activation of cell groups may enable subsequent configuration after a cell group (CG) change without the network needing to reconfigure or reinitialize the corresponding cell group selective activation configuration information, thereby reducing signaling overhead and disruption time associated with cell group changes.

[0055] Among these, the cell group selective activation setting information may include at least one of a setting ID, an activation condition (if possible), and a setting of a cell and / or cell group to be activated.

[0056] Among these, the selective activation of a cell group can perform subsequent configuration after a cell group change without the network needing to reset or reinitialize the corresponding cell group selective activation configuration. Therefore, in the selective activation of a cell group, a network device can provide a "cell group to be activated" to a terminal, and can subsequently activate or deactivate the "cell group to be activated" without re-providing the cell group configuration again.

[0057] In the selective activation of a cell group, a network device may provide a terminal device with a preconfigured candidate target cell group or target cell. Subsequently, the terminal device may activate or deactivate the preconfigured candidate cell and / or cell group according to a configuration (e.g., an activation message) issued by the network device or a corresponding activation event without re-provisioning the cell group configuration. Alternatively, in the selective activation of a cell group, after activating a new cell or cell group, applying a new cell configuration or cell group configuration, or accessing a new cell or cell group, the terminal does not delete the corresponding cell group selective activation configuration information.

[0058] The selective activation of a cell group is also referred to as cell group activation. Cell group activation allows the network to execute corresponding configuration information after a cell and / or cell group change without having to reconfigure or reinitialize the corresponding cell group activation configuration information. Therefore, cell group selective activation can reduce signaling overhead and interruption time associated with a cell group change. The configuration information of the cell group activation may include a configuration ID and a target cell configuration or a target cell group configuration. Optionally, the configuration information of the cell group activation may further include a trigger condition (or an execution condition, also referred to as an activation condition).

[0059] In some embodiments, the cell group selective activation is a mobility management process including any kind of mobility management process in which the terminal activates or deactivates a corresponding cell or cell group, or applies a corresponding cell configuration or cell group configuration, or accesses a cell or cell group, by setting a cell group activation configuration, based on signaling sent from the network side, or based on criteria specified in a protocol, or autonomously by the terminal.

[0060] In some embodiments, the cell group selective activation is a mobility management process, including any type of mobility management process, that does not delete or release some or all of the corresponding configuration information after the mobility process is performed. Not deleting or releasing some or all of the corresponding configuration information can also be referred to as retaining some or all of the corresponding configuration information.

[0061] This paper introduces Layer 1 or Layer 2-triggered mobility (LTM).

[0062] In a 5G system, a network side can provide a terminal with multiple "candidate cells (candidate cell groups)." In some embodiments, the network side can subsequently control the terminal to change the multiple "candidate cells (candidate cell groups)" via L1 signaling (e.g., Downlink Control Information (DCI)) or L2 signaling (e.g., Media Access Control Element (MAC CE)). For example, the working cell (cell group) can be changed from "candidate cell (candidate cell group)-1" to "candidate cell (candidate cell group)-2." Among these, one serving cell (serving cell group) can correspond to one or more "candidate cells (candidate cell groups)."

[0063] In some embodiments, the first layer of 5G is the physical layer, the second layer includes MAC, Radio Link Control (RLC), and Packet Data Convergence Protocol (PDCP), and the third layer is the RRC layer.

[0064] Scenarios supported by LTM In Rel-18, L1 / L2 mobility includes both non-CA (PCell only) and CA scenarios (PCell and SCell). This includes the following cases: a) When the target PCell / target SCell(s) is not a current serving cell (CA scenario with PCell change) JPEG2026506094000029.jpg13134b) If the target PCell is a current SCell c) If the target SCell is the current PCell

[0065] L1L2 based mobility supports the following CA scenarios: a) PCell change without SCell change b) PCell change with SCell change c) In L1 / L2 based mobility, support the NR-DC scenario, at least for the PSCell change without MN involvement (i.e., intra-SN).

[0066] For CPA / CPCs configured by different nodes, the measurement configurations referenced by the CPA / CPC may be different. Therefore, before performing measurement evaluation, it is necessary to determine the measurement configurations corresponding to the execution conditions of the CPA / CPC. For CPA / CPCs initiated by the S-MN and S-SN, the execution conditions are set by the S-MN and S-SN, so the terminal can know the measurement configurations corresponding to the relevant conditions of the CPA / CPC, that is, the measurement configurations corresponding to the terminal's current MCG and SCG.

[0067] However, for CPA / CPC initiated by the T-MN, its execution conditions are determined by the T-MN and transmitted to the UE via the target PCell. The CPA / CPC conditions configured by the T-MN are determined based on the measurement configuration provided by the target PCell. Therefore, when the UE evaluates the CPA / CPC execution conditions, it needs to obtain the measurement configuration of the target PCell. When CHO and CPAC are jointly configured, the target PSCell corresponding to CPAC is associated with the target PCell corresponding to the corresponding CHO. Because there are multiple candidate PCells, the measurement configurations for different target PCells are also different. Only by accessing the target PCell can the UE know the measurement configuration corresponding to the target PCell and perform CPAC. If CHO and CPAC evaluation need to be performed in parallel, existing communication protocols prevent the UE from obtaining the measurement configuration corresponding to the CPAC conditions before performing CHO. In other words, it is impossible to perform CHO and CPAC simultaneously.

[0068] The method provided by the embodiments of the present application clarifies how a terminal acquires a measurement configuration corresponding to an execution condition of the condition-based mobility configuration for the SCG / PSCell when the condition-based mobility configuration for the MCG / PCell and the condition-based mobility configuration for the SCG / PSCell are jointly configured. For example, when the CHO for the MCG / PCell and the CPA / CPC for the SCG / PSCell are simultaneously configured, the method clarifies how a terminal acquires a measurement configuration corresponding to an execution condition of the CPA / CPC. Because the mobility configuration of the SCG / PSCell is associated with a candidate MCG / PCell corresponding to a candidate SCG / PSCell, a mobility operation initiated by the T-MN is realized, and the terminal can acquire a measurement configuration corresponding to an execution condition of the mobility configuration of the SCG / PSCell before switching to the MCG / PCell corresponding to the T-MN. For example, the terminal can acquire a measurement configuration corresponding to an execution condition of the CPA / CPC without waiting for the execution of the CHO, so that the terminal can execute the CHO and the CPA / CPC simultaneously. In this method, the present application also proposes a configuration storage method for maintaining different terminal measurement variables (first variables) and conditional reconfiguration variables (second variables) of SCG / PSCell mobility configuration for different T-MNs. For SCG / PSCell mobility configurations configured by different T-MNs, the SCG / PSCell mobility configurations and corresponding measurement configurations are stored correspondingly via variables stored in different terminals, thereby realizing a correspondence relationship between an execution condition for instructing SCG / PSCell mobility configuration and the corresponding measurement configuration. For example, the correspondence relationship is between an execution condition for instructing CPAC conditional reconfiguration and the corresponding measurement configuration.

[0069] The method provided by the embodiments of the present application also proposes a method for solving the problem that a UE cannot simultaneously perform MCG / PCell mobility operation and SCG / PSCell mobility operation (e.g., cannot simultaneously perform CHO and CPAC) through inter-network negotiation. Through inter-network negotiation, a measurement identifier corresponding to the execution condition of SCG / PSCell mobility operation can be associated with the UE's current measurement configuration, so that the UE can obtain the measurement configuration for SCG / PSCell mobility operation without waiting for MCG / PCell mobility operation. For example, since the measurement configuration for CPAC can be obtained without waiting for CHO, the UE can simultaneously perform CHO and CPA / CPC.

The communication system 400 may include a terminal 401, an access network device 402, an access network device 403, an access network device 404, and a core network device 405.

[0071] The number of terminals 401 is usually plural, and one or more terminals 401 can be distributed within a cell managed by each access network device 402. The terminals 401 include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, each equipped with wireless communication capabilities, as well as various forms of user equipment (UE), mobile stations (MS), etc. For convenience of explanation, the above devices will be collectively referred to as terminals in the embodiments of this application.

The access network device 402, the access network device 403, and the access network device 404 include various types of macro base stations, micro base stations, relay stations, and access points. In systems using different radio access technologies, devices with access network device functions may be named differently. For example, in a 5G NR system, they are referred to as gNodeBs or gNBs. By way of example, continuing to refer to FIGS. 1 and 2, a device with access network device functions in a dual connectivity scenario may also be referred to as en-gNBs (e.g., a 5G base station accessing an LTE core network) or ng-eNBs (e.g., an LTE base station accessing a 5G core network). As communication technologies evolve, the name of the "access network device" may change. For convenience of explanation, in the embodiments of the present application, the above devices providing wireless communication functions to the terminal 401 are collectively referred to as access network devices. Connections are established between the access network device 402, the access network device 403, and the access network device 404 and the terminal 401 via a wireless interface, and communication including exchange of signaling and data can be performed via these connections. There are multiple access network devices 402, 403, and 404, and two adjacent access network devices 402, 403, and 404 can communicate with each other via wired or wireless means (connection to the access network device 404 is not shown in FIG. 4).

[0073] As shown in FIG. 4 , in some embodiments, a terminal establishes a dual connection with access network device 402 and access network device 403. Among these, m cells among the multiple cells provided by access network device 402 constitute an MCG for terminal 401 through carrier aggregation, and n cells among the multiple cells provided by access network device 403 constitute an SCG for terminal 401 through carrier aggregation. The MCG for terminal 401 includes one PCell (e.g., cell 1 in the MCG) and multiple SCells, and the SCG for terminal 401 (e.g., cell 1 in the SCG) includes one PSCell and multiple SCells. Access network device 402 may be referred to as the S-MN of the terminal, and access network device 403 may be referred to as the S-SN of the terminal. If terminal 401 evaluates that a condition is met, it may perform mobility operations such as CHO, CPA, CPC, and cell group / cell selective activation. In order for a terminal to perform mobility operations, the terminal needs to be provided with a candidate MCG / PCell and / or a candidate SCG / PSCell. An access network device that provides a candidate MCG / PCell to a terminal can be referred to as the T-MN of the terminal, and an access network device that provides a candidate SCG / PSCell to a terminal can be referred to as the T-SN of the terminal, for example, access network device 404 in FIG. 4.

[0074] The functions of the core network device 405 are mainly to provide user connection, user management, and service bearing, and to provide an interface to external networks as a bearer network. The access network device 402, the access network device 403, the access network device 404, and the core network device 405 are collectively referred to as network devices. The core network device 405 communicates with the access network device 402, the access network device 403, and the access network device 404 via some wireless technology (connection to the access network device 404 is not shown in FIG. 4), and a communication relationship can be established between the terminal 401 and the core network device 405 via the access network device 402, the access network device 403, and the access network device 404.

[0075] Note that the number of communication devices in the system shown in Figure 4 is merely an example, and the number of communication devices may be greater, and the connection relationships may also be changed according to actual circumstances. The example of Figure 4 does not limit the communication system provided by the embodiments of the present application.

[0076] The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, the meaning of which is understood by those skilled in the art. The technical solutions described in the embodiments of the present application can be applied not only to the 5G NR system but also to systems evolved after the 5G NR system.

[0098] In some embodiments, L1 / L2 triggered SCG / PSCell mobility (LTM-SCG / PSCell) is used to control a terminal to change its serving MCG / PCell from among multiple candidate SCG / PSCells corresponding to the terminal's serving SCG / PSCell.

The indication information is used to indicate the purpose of the configuration indicated by the information, for example, indicating that the purpose is one or more of CPA, CPC, and SCG / PSCell selective activation.

The CHO configuration includes a CHO execution condition and a configuration corresponding to a candidate MCG, and the configuration corresponding to the candidate MCG includes one or more CPC / CPA configurations and configuration information corresponding to a subsequent MCG. The subsequent MCG refers to a candidate MCG to which the terminal may switch when switching again after switching to the candidate MCG.

[0102] Step 504: The first mobility configuration corresponding to the candidate MCG / PCell and the second mobility configuration corresponding to the candidate SCG / PSCell are associated with each other and stored.

[0103] About Storing Mobility Configuration The first mobility configuration and the second mobility configuration received by the terminal can be regarded as a joint mobility configuration such as a joint configuration of CHO and CPAC. After receiving the mobility configuration, the terminal stores it.

Optionally, the candidate SCG / PSCell is an SCG / PSCell that the terminal can access after evaluating the execution conditions of the second mobility configuration. The candidate SCG includes one or more SCGs, and the candidate PSCell includes one or more PSCells.

[0106] In some embodiments, the methods provided by the embodiments of the present application are applied to a dual connectivity scenario, in which candidate MCG / PCells are associated with candidate SCG / PSCells, and each candidate MCG / PCell corresponds to one or more candidate SCG / PSCells.

[0107] In some embodiments, when storing the first mobility configuration and the second mobility configuration, the terminal stores the first mobility configuration corresponding to the candidate MCG / PCell and / or stores the second mobility configuration corresponding to all or a part (one or more) of the candidate SCG / PSCells associated with the candidate MCG / PCell in a variable corresponding to the candidate MCG / PCell. In the storing process, the terminal may store the first mobility configuration and the second mobility configuration together in the variable corresponding to the candidate MCG / PCell, or may store the first mobility configuration and the second mobility configuration separately.

[0108] Illustratively, the first mobility configuration is a candidate target configuration (a configuration corresponding to the candidate MCG / PCell) corresponding to the candidate MCG / PCell, which includes a configuration corresponding to the candidate MCG / PCell, such as a measurement configuration.

[0109] Illustratively, the second mobility configuration is a condition-triggered mobility configuration corresponding to the candidate SCG / PSCell, which includes one or more of a configuration identifier, an execution condition, and a candidate target configuration (a configuration corresponding to the candidate SCG / PSCell).

The terminal stores the first mobility configuration corresponding to the candidate MCG / PCell in the first variable corresponding to the candidate MCG / PCell. Optionally, the first variable may be referred to as a terminal (UE) variable or a Var (Variable) variable.

[0114] To store the complete measurement configuration In some embodiments, when storing the first mobility configuration, the terminal stores a measurement configuration (complete measurement configuration) corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell. Among them, the measurement configuration corresponding to the candidate MCG / PCell is determined according to the first mobility configuration. This measurement configuration corresponds to an execution condition of the first mobility configuration and is used by the terminal to perform measurements via the measurement configuration and evaluate whether the execution condition is met. Optionally, the first variable storing the measurement configuration is a measurement configuration variable (VarMeasConfig).

[0115] In some embodiments, the first mobility configuration includes a configuration corresponding to the candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes a measurement configuration corresponding to the candidate MCG / PCell, that is, the terminal can directly obtain the measurement configuration corresponding to the candidate MCG / PCell through the first mobility configuration.

[0116] In some embodiments, the first mobility configuration includes a configuration corresponding to a candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes measurement configuration information (incremental configuration) corresponding to the candidate MCG / PCell. The terminal may generate a measurement configuration corresponding to the candidate MCG / PCell based on the measurement configuration of the serving MCG / PCell and the measurement configuration information corresponding to the candidate MCG / PCell, and store the measurement configuration (complete measurement configuration) corresponding to the candidate MCG / PCell.

[0117] When storing incremental settings In some embodiments, the first mobility configuration includes a configuration corresponding to a candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes measurement configuration information (incremental configuration) corresponding to the candidate MCG / PCell. When storing the first mobility configuration, the terminal stores the measurement configuration information corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell. Among them, the measurement configuration information corresponding to the candidate MCG / PCell is used to generate the measurement configuration corresponding to the candidate MCG / PCell. By storing only the incremental configuration, the storage capacity of the terminal is optimized.

[0118] Optionally, the first variable is Setting table, Measurement quantity setting, · Measurement start threshold (s-MeasureConfig), Measurement gap setting, It contains one or more pieces of information.

[0119] Optionally, the first variable may include a measurement setting, such as one or more of a measurement object setting, a measurement identifier setting, and a report setting.

[0127] For example, a specific procedure for a terminal to generate and store a measurement configuration corresponding to a candidate MCG based on the measurement configuration of the current serving MCG and the incremental configuration (incremental measurement configuration) included in the configuration corresponding to the candidate MCG may be: the terminal adds or modifies the configuration corresponding to the current serving MCG based on a configuration addition / modification table included in the incremental configuration of the candidate MCG to obtain the configuration corresponding to the candidate MCG; the terminal deletes the configuration corresponding to the current serving MCG based on a configuration deletion table included in the incremental configuration of the candidate MCG to obtain the configuration corresponding to the candidate MCG; the terminal updates the configuration corresponding to the current serving MCG using the measurement quantity configuration, measurement start threshold, and measurement gap configuration in the incremental configuration (if any), obtains the configuration corresponding to the candidate MCG, and stores it via a first variable corresponding to the candidate MCG.

[0128] In some embodiments, the first variable may be VarMeasConfig.

[0129] About Storing Secondary Mobility Settings In some embodiments, each candidate MCG / PCell corresponds to one separate second variable. The terminal stores second mobility configurations corresponding to candidate SCG / PSCells associated with the candidate MCG / PCell in the second variable corresponding to the candidate MCG / PCell. Optionally, the second variable may be referred to as a terminal (UE) variable or a Var variable. The second variable is used to store second mobility configurations corresponding to one or more candidate SCG / PSCells corresponding to the corresponding candidate MCG / PCell. In some embodiments, the second variable is a conditional reset variable (VarConditionalReconfig).

[0130] In some embodiments, the second variable includes a field representing a mobility configuration, such as a conditional reconfiguration table (condReconfigList), and indicates that the second variable is used to store the mobility configuration. Optionally, the field representing the mobility configuration is represented by a conditional reconfiguration add-mod table (CondReconfigToAddModList).

[0131] In some embodiments, for a joint mobility configuration, if the configuration corresponding to a candidate MCG included in the mobility configuration of the candidate MCG includes mobility configurations of one or more candidate SCGs associated with the candidate MCG, in response to the terminal receiving this joint mobility configuration, the terminal reads the configuration corresponding to the candidate MCG from the mobility configuration of the candidate MCG and stores the mobility configurations of one or more candidate SCGs associated with the candidate MCG using a second variable corresponding to this candidate MCG.

[0132] Illustratively, the joint mobility configuration is CHO+CPC, the candidate MCG of each CHO corresponds to one second variable, and the terminal stores, via the second variable, the CPC configuration of one or more (all) SCGs corresponding to the candidate MCG to which the CHO is configured.

[0133] In some embodiments, the terminal stores the first mobility configuration using only the first variable. In some embodiments, the terminal stores the second mobility configuration using only the second variable. In some embodiments, the terminal stores the first mobility configuration using the first variable and stores the second mobility configuration using the second variable.

[0134] Exemplarily, the first mobility configuration includes a CHO configuration of candidate PCell 1, and the second mobility configuration includes CPAC configurations of candidate PSCell 1, candidate PSCell 2, and candidate PSCell 3. Then, candidate PCell 1 is associated with candidate PSCell 1, candidate PSCell 2, and candidate PSCell 3. When storing the first mobility configuration and the second mobility configuration, the terminal stores the CHO configuration of candidate PSCell 1 in a first variable corresponding to candidate PSCell 1, and stores the CPAC configurations of candidate PSCell 1, candidate PSCell 2, and candidate PSCell 3 in a second variable corresponding to PSCell 1.

[0135] About Using Mobility Settings In some embodiments, in the process of evaluating the execution conditions of the third mobility configuration, the UE may determine whether to perform the mobility operation of the third mobility configuration by directly using and evaluating the measurement configuration of the source MCG / PCell configuration, for example, to determine whether to perform selective activation of CHO, MCG / PCell.

[0136] In some embodiments, in the process of evaluating the execution conditions of the second mobility configuration, the UE may determine whether to perform the mobility operation of the second mobility configuration by directly using and evaluating the measurement configuration of the first mobility configuration corresponding to the corresponding candidate MCG / PCell, for example, to determine whether to perform selective activation of the CPA / CPC, SCG / PSCell.

[0137] In some embodiments, the second mobility configuration is used for SCG / PSCell mobility triggered by a condition, such as CPA, CPC, and SCG selective activation. In some embodiments, in the process in which the terminal evaluates an execution condition for SCG / PSCell mobility, the terminal performs measurement based on a measurement configuration stored in a first variable corresponding to a candidate MCG / PCell associated with the mobility configuration of the candidate SCG / PSCell, and evaluates whether an event corresponding to this execution condition is satisfied.

[0138] Illustratively, when performing a CPAC event evaluation, the terminal performs measurements based on the measurement settings stored in the first variable corresponding to the candidate MCG associated with the CPAC, and evaluates whether the CPAC event is satisfied.

[0139] If the device stores the complete measurement configuration In some embodiments, in the process in which the terminal evaluates the execution conditions of the second mobility configuration, the terminal performs measurements based on the measurement configuration stored in the first variable corresponding to the candidate MCG / PCell associated with the second mobility configuration.

[0140] Illustratively, the terminal may perform measurements based solely on the measurement configuration stored in the first variable corresponding to the candidate MCG to evaluate whether an event corresponding to an execution condition corresponding to the mobility configuration of the candidate SCG associated with this candidate MCG is satisfied.

[0141] If the device stores incremental settings In some embodiments, in a process in which the terminal evaluates the execution condition of the second mobility configuration, the terminal performs measurement based on the measurement configuration of the serving MCG / PCell and the measurement configuration corresponding to the candidate MCG / PCell, where the measurement configuration information of the serving MCG / PCell and the measurement configuration corresponding to the candidate MCG / PCell is used by the terminal to generate the measurement configuration corresponding to the candidate MCG / PCell.

[0142] Illustratively, the terminal may obtain the measurement configuration corresponding to the candidate MCG based on the measurement configuration stored in the first variable corresponding to the candidate MCG and the measurement configuration corresponding to the current serving MCG, and then perform a measurement to evaluate whether an event corresponding to an execution condition corresponding to the mobility configuration of the candidate SCG associated with the candidate MCG is satisfied.

[0143] What happens to the stored mobility configuration after you perform a mobility operation? Optionally, the first mobility configuration includes a configuration of a CHO, and the second mobility configuration includes a configuration of a CPAC. In the case of a joint configuration of a CHO and a CPAC If the device runs CHO and CPAC In some embodiments, after the terminal performs CHO and CPAC, the terminal clears all second variables. For example, the terminal deletes all entries in the Var variable (i.e., the second variable) that stores all conditional reconfiguration settings. That is, the terminal clears the second variables corresponding to each candidate MCG / PCell and the second variables corresponding to the serving MCG / PCell.

[0144] In some embodiments, after the terminal performs CHO and CPAC, the terminal updates the first variable corresponding to the candidate MCG / PCell that the terminal has determined to access to the first variable corresponding to the terminal's serving MCG / PCell. Optionally, if the first mobility configuration includes a complete measurement configuration, the terminal updates the first variable corresponding to the candidate MCG / PCell to be accessed to the first variable of the serving MCG / PCell. If the first mobility configuration includes an incremental configuration, the terminal may obtain the measurement configuration corresponding to the candidate MCG / PCell to be accessed in combination with the measurement configuration of the previous serving MCG / PCell based on the incremental configuration of the first variable corresponding to the candidate MCG / PCell to be accessed, and store the measurement configuration in the first variable corresponding to the candidate MCG / PCell to be accessed. The terminal then updates this to the first variable of the serving MCG newly accessed by the terminal.

[0145] In some embodiments, after the terminal performs CHO and CPAC, the terminal clears first variables corresponding to candidate MCG / PCells other than the candidate MCG / PCell that the terminal has determined to access.

[0146] In the first case, the terminal only executes CHO and does not execute CPAC. In this case, the terminal can perform the same procedure as in "When the terminal performs CHO and CPAC" above. That is, the terminal performs the above procedure appropriately after CHO.

[0147] In the second case, the terminal only executes CHO and does not execute CPAC. In some embodiments, when the terminal performs CHO but does not perform CPAC, the terminal clears second variables corresponding to candidate MCGs / PCells other than the candidate MCG / PCell that the terminal has decided to access. For example, the terminal deletes all entries in the Var variable (i.e., the second variable) that stores conditional reconfiguration configurations corresponding to candidate MCGs other than the candidate MCG that the terminal has decided to access. That is, the terminal clears the second variables corresponding to the other candidate MCGs and the second variable corresponding to the serving MCG. In some embodiments, when the terminal performs CHO and does not perform CPAC, the terminal updates the second variable corresponding to the candidate MCG / PCell that the terminal has determined to access to the second variable corresponding to the terminal's serving MCG / PCell.

[0148] In summary, in the method provided by this embodiment, when a first mobility configuration and a second mobility configuration are jointly configured, the first mobility configuration of a candidate MCG / PCell and the second mobility configuration of a candidate SCG / PSCell corresponding to the candidate MCG / PCell are associated and stored via the terminal, so that the terminal can determine the second mobility configuration corresponding to a different candidate SCG / PSCell without performing a mobility operation for the first mobility configuration. For example, the terminal can determine a CPAC configuration for a different candidate SCG / PSCell without performing CHO. The terminal can simultaneously perform mobility operations for the first mobility configuration and the second mobility configuration.

[0149] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

This method can be applied to a terminal. In some embodiments, this method can be used for a terminal in the system shown in FIG. 4. This method includes the following steps:

[0151] Step 602: Receive a condition-based mobility configuration sent from a network device.

[0152] The condition-based mobility configuration includes a first mobility configuration and a second mobility configuration. The first mobility configuration is a configuration for MCG / PCell mobility, and the second mobility configuration is a configuration for SCG / PSCell mobility. In some embodiments, the terminal receives the first mobility configuration and the second mobility configuration transmitted simultaneously by the network device. In some embodiments, the terminal receives the first mobility configuration and the second mobility configuration transmitted at different times by the network device.

[0153] For a detailed description of the mobility configuration, please refer to the related content of the embodiment in Figure 5. The embodiment of this application does not describe it in detail.

[0154] Step 604: Store the first mobility configuration corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell.

[0155] In some embodiments, each candidate MCG / PCell corresponds to one separate first variable, and the terminal stores the first mobility configuration corresponding to the candidate MCG / PCell in the first variable corresponding to the candidate MCG / PCell. Optionally, the first variable may be referred to as a terminal (UE) variable or a Var variable.

[0156] In some embodiments, when storing the first mobility configuration, the terminal stores the measurement configuration (complete measurement configuration) corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell, where the measurement configuration corresponding to the candidate MCG / PCell is determined according to the first mobility configuration.

[0157] In some embodiments, the first mobility configuration includes a configuration corresponding to a candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes measurement configuration information (incremental configuration) corresponding to the candidate MCG / PCell. When storing the first mobility configuration, the terminal stores the measurement configuration information corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell. Among them, the measurement configuration information corresponding to the candidate MCG / PCell is used to generate a measurement configuration corresponding to the candidate MCG / PCell.

[0158] In some embodiments, some of the configuration information in the first mobility configuration is used by the terminal to perform an associated process of a second mobility configuration corresponding to a candidate SCG / PSCell associated with the candidate MCG / PCell, for example, the first mobility configuration corresponding to the candidate MCG / PCell includes information for determining a measurement configuration corresponding to the candidate MCG / PCell.

[0159] For a detailed description of the storage of mobility settings, please refer to the relevant content of the embodiment in Figure 5. The embodiment of this application does not provide a detailed description thereof.

[0160] In summary, in the method provided by this embodiment, when a first mobility configuration and a second mobility configuration are jointly configured, the first mobility configuration of a candidate MCG / PCell is stored in a corresponding first variable via the terminal, and part of the configuration information in the first mobility configuration is used by the terminal to perform a process related to the second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell. This allows the terminal to determine information required for evaluation using the second mobility configuration corresponding to a different candidate SCG / PSCell without performing mobility operations for the first mobility configuration. For example, the terminal can determine CPAC configurations for different candidate SCGs / PSCells without performing CHO. The terminal can simultaneously perform mobility operations for the first mobility configuration and the second mobility configuration.

[0161] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments.

[0162] 7 shows a flowchart of a condition-based mobility configuration method provided by one embodiment of the present application. This method can be applied to a terminal. In some embodiments, this method can be used for a terminal in the system shown in FIG. 4. This method includes the following steps:

[0163] Step 702: Receive a condition-based mobility configuration sent by a network device.

[0164] The condition-based mobility configuration includes a first mobility configuration and a second mobility configuration. The first mobility configuration is a configuration for MCG / PCell mobility, and the second mobility configuration is a configuration for SCG / PSCell mobility. In some embodiments, the terminal receives the first mobility configuration and the second mobility configuration transmitted simultaneously by the network device. In some embodiments, the terminal receives the first mobility configuration and the second mobility configuration transmitted at different times by the network device.

[0165] For a detailed description of the mobility configuration, please refer to the related content of the embodiment in Figure 5. The embodiment of this application does not describe it in detail.

[0166] Step 704: Store a second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell in a second variable corresponding to the candidate MCG / PCell.

[0167] In some embodiments, each candidate MCG / PCell corresponds to one separate second variable. The terminal stores the second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell in the second variable corresponding to the candidate MCG / PCell. Optionally, the second variable may be referred to as a terminal (UE) variable or a Var variable.

[0168] In some embodiments, the terminal may determine a second mobility configuration corresponding to a different candidate MCG / PCell based on a second variable corresponding to the different candidate MCG / PCell, and then combine the measurement configurations corresponding to the different candidate MCG / PCell to determine a correspondence relationship between the second mobility configuration and the measurement configuration corresponding to the same candidate MCG / PCell. In some embodiments, part of the configuration information in the first mobility configuration is used by the terminal to perform an association process of the second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell. For example, the first mobility configuration corresponding to the candidate MCG / PCell includes information for determining the measurement configuration corresponding to the candidate MCG / PCell.

[0169] For a detailed description of the storage of mobility settings, please refer to the relevant content of the embodiment in Figure 5. The embodiment of this application does not provide a detailed description thereof.

[0170] In summary, when a first mobility configuration and a second mobility configuration are jointly configured, the method provided by this embodiment establishes an association relationship between the measurement configuration corresponding to the candidate MCG / PCell and the second mobility configuration by storing the second mobility configuration of the candidate SCG / PSCell corresponding to the candidate MCG / PCell in a corresponding second variable via the terminal. The terminal can determine the measurement configuration corresponding to the second mobility configuration corresponding to a different candidate SCG / PSCell without performing a mobility operation for the first mobility configuration. For example, the terminal can determine the CPAC configuration for a different candidate SCG / PSCell without performing a CHO. The terminal can simultaneously perform the mobility operation for the first mobility configuration and the mobility operation for the second mobility configuration.

[0171] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0172] Measurement of a terminal using a first mobility configuration and a second mobility configuration based on jointly configured conditions 8 shows a flowchart of a condition-based mobility measurement method provided by one embodiment of the present application. This method can be applied to a terminal. In some embodiments, this method can be used for a terminal in the system shown in FIG. 4. This method includes the following steps:

[0173] Step 802: In the process of evaluating the execution conditions of the second mobility configuration, perform measurements based on information stored in a first variable corresponding to a candidate MCG / PCell associated with the second mobility configuration.

[0174] The terminal stores a first mobility configuration and a second mobility configuration that are jointly configured.

[0175] In some embodiments, the terminal stores a first mobility configuration corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell. Optionally, the terminal may store a measurement configuration corresponding to the candidate MCG / PCell (complete measurement configuration) or measurement configuration information corresponding to the candidate MCG / PCell (incremental configuration). The measurement configuration information corresponding to the candidate MCG / PCell is used to generate a measurement configuration corresponding to the candidate MCG / PCell.

[0176] In some embodiments, the terminal stores, in a second variable corresponding to the candidate MCG / PCell, a second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell.

[0177] In some embodiments, in the process in which the terminal evaluates the execution conditions of the second mobility configuration, the terminal performs measurements based on the measurement configuration stored in the first variable corresponding to the candidate MCG / PCell associated with the second mobility configuration.

[0178] In some embodiments, in a process in which the terminal evaluates the execution condition of the second mobility configuration, the terminal performs measurement based on the measurement configuration of the serving MCG / PCell and the measurement configuration information corresponding to the candidate MCG / PCell, where the measurement configuration of the serving MCG / PCell and the measurement configuration information corresponding to the candidate MCG / PCell are used by the terminal to generate the measurement configuration corresponding to the candidate MCG / PCell.

[0179] In summary, in the method provided by this embodiment, when a first mobility configuration and a second mobility configuration are jointly configured, in a process in which the UE evaluates an execution condition for the second mobility configuration, the UE can perform related measurements based on information of a first variable corresponding to a candidate MCG / PCell. The UE can determine CPAC configurations for different candidate SCGs / PSCells without performing CHO, so that the UE can simultaneously perform mobility operations for the first mobility configuration and the second mobility configuration.

[0180] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0181] Regarding processing of stored mobility configurations after performing mobility operations using jointly configured condition-based first and second mobility configurations 9 is a flowchart of a method for processing condition-based mobility configuration provided by one embodiment of the present application. This method can be applied to a terminal. In some embodiments, this method can be used for a terminal in the system shown in FIG. 4. This method includes the following steps:

[0182] Step 902: After the terminal executes CHO and / or CPAC, process the first variable and the second variable stored in the terminal.

[0183] The terminal stores a first mobility configuration and a second mobility configuration that are jointly configured.

[0184] In some embodiments, the terminal stores a first mobility configuration corresponding to the candidate MCG / PCell in a first variable corresponding to the candidate MCG / PCell. Optionally, the terminal may store a measurement configuration corresponding to the candidate MCG / PCell (complete measurement configuration) or measurement configuration information corresponding to the candidate MCG / PCell (incremental configuration). The measurement configuration information corresponding to the candidate MCG / PCell is used to generate a measurement configuration corresponding to the candidate MCG / PCell.

[0185] In some embodiments, the terminal stores, in a second variable corresponding to the candidate MCG / PCell, a second mobility configuration corresponding to the candidate SCG / PSCell associated with the candidate MCG / PCell.

[0186] Optionally, the first mobility configuration includes a configuration of a CHO, and the second mobility configuration includes a configuration of a CPAC.

[0187] If the device runs CHO and CPAC In some embodiments, after the terminal executes CHO and CPAC, the terminal clears all second variables.

[0188] In some embodiments, after the terminal performs CHO and CPAC, the terminal updates the first variable corresponding to the candidate MCG / PCell that the terminal has determined to access to the first variable corresponding to the terminal's serving MCG / PCell. Optionally, if the first mobility configuration includes a complete measurement configuration, the terminal updates the first variable corresponding to the candidate MCG / PCell to be accessed to the first variable of the serving MCG / PCell. If the first mobility configuration includes an incremental configuration, the terminal may obtain the measurement configuration corresponding to the candidate MCG / PCell to be accessed in combination with the measurement configuration of the previous serving MCG / PCell based on the incremental configuration of the first variable corresponding to the candidate MCG / PCell to be accessed, and store the measurement configuration in the first variable corresponding to the candidate MCG / PCell to be accessed. The terminal then updates this to the first variable of the serving MCG newly accessed by the terminal.

[0189] In some embodiments, after the terminal performs CHO and CPAC, the terminal clears first variables corresponding to candidate MCG / PCells other than the candidate MCG / PCell that the terminal has determined to access.

[0190] In the first case, the terminal only executes CHO and does not execute CPAC. In this case, the terminal can perform the same procedure as in "When the terminal performs CHO and CPAC" above. That is, the terminal performs the above procedure appropriately after CHO.

[0191] In the second case, the terminal only executes CHO and does not execute CPAC. In some embodiments, when the terminal performs CHO but does not perform CPAC, the terminal clears second variables corresponding to candidate MCGs / PCells other than the candidate MCG / PCell that the terminal has decided to access. For example, the terminal deletes all entries in the Var variable (i.e., the second variable) that stores conditional reconfiguration configurations corresponding to candidate MCGs other than the candidate MCG that the terminal has decided to access. That is, the terminal clears the second variables corresponding to the other candidate MCGs and the second variable corresponding to the serving MCG.

[0192] In some embodiments, when the terminal performs CHO and does not perform CPAC, the terminal updates the second variable corresponding to the candidate MCG / PCell that the terminal has determined to access to the second variable corresponding to the terminal's serving MCG / PCell.

[0193] In summary, in the method provided by this embodiment, when a first mobility setting and a second mobility setting are jointly set, after the terminal executes CHO and / or CPAC, the terminal processes the stored first variables and second variables to clear unavailable mobility settings and ensure that the mobility settings currently stored in the terminal are available, thereby optimizing the storage capacity of the terminal.

[0194] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0195] 10 shows a flowchart of a condition-based mobility configuration method provided by an embodiment of the present application, which can be applied to network devices. The method includes the following steps:

[0196] Step 1002: Send a condition-based mobility configuration to a terminal.

[0197] The condition-based mobility configuration includes a first mobility configuration and a second mobility configuration. The first mobility configuration is a configuration for MCG / PCell mobility, and the second mobility configuration is a configuration for SCG / PSCell mobility. The first mobility configuration corresponding to a candidate MCG / PCell and the second mobility configuration corresponding to a candidate SCG / PSCell are associated with each other and stored by the terminal.

[0198] In some embodiments, the network device transmits the first mobility configuration and the second mobility configuration to the terminal simultaneously. In some embodiments, the network device transmits the first mobility configuration and the second mobility configuration to the terminal at different times.

[0199] In some embodiments, the network device is the S-MN of the terminal. In some embodiments, the network device is the S-SN of the terminal. In some embodiments, the second mobility configuration is initiated and configured by the T-MN.

[0200] Exemplarily, the second mobility configuration may be initiated by the T-MN and forwarded to the terminal by the S-MN.

[0201] Illustratively, part of the content of the second mobility configuration may be obtained from the T-SN.

[0202] In some embodiments, part of the configuration information in the first mobility configuration is used by the terminal to perform related processes of a second mobility configuration corresponding to a candidate SCG / PSCell associated with the candidate MCG / PCell.

[0203] In some embodiments, the first mobility configuration includes a configuration corresponding to the candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes a measurement configuration corresponding to the candidate MCG / PCell.

[0204] In some embodiments, the first mobility configuration includes a configuration corresponding to a candidate MCG / PCell, and the configuration corresponding to the candidate MCG / PCell includes measurement configuration information corresponding to the candidate MCG / PCell, where the measurement configuration information corresponding to the candidate MCG / PCell is used to generate a measurement configuration corresponding to the candidate MCG / PCell.

[0208] In some embodiments, the second mobility configuration comprises: a configuration identifier, Execution conditions, Configuration corresponding to the candidate MCG / PCell and / or configuration corresponding to the candidate SCG / PSCell, ·Instruction information, It includes at least one of the following information.

[0209] In some embodiments, the first mobility configuration includes a configuration corresponding to a candidate MCG / PCell, and the second mobility configuration is transmitted in the configuration corresponding to the candidate MCG / PCell.

[0210] For a detailed description of the mobility configuration, please refer to the related content of the embodiment in Figure 5. The embodiment of this application does not describe it in detail.

[0211] In summary, in the method provided by this embodiment, when a first mobility configuration and a second mobility configuration are jointly configured, the first mobility configuration of a candidate MCG / PCell and the second mobility configuration of a candidate SCG / PSCell corresponding to the candidate MCG / PCell are associated and stored via the terminal, so that the terminal can determine the second mobility configuration corresponding to a different candidate SCG / PSCell without performing a mobility operation for the first mobility configuration. For example, the terminal can determine a CPAC configuration for a different candidate SCG / PSCell without performing CHO. The terminal can simultaneously perform mobility operations for the first mobility configuration and the second mobility configuration.

[0212] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0213] 11 shows a flowchart of a condition-based mobility configuration method provided by one embodiment of the present application. In some embodiments, this method can be used in the system shown in FIG. 4. The method includes the following steps:

[0214] Step 1102: The network device sends a condition-based mobility configuration to the terminal.

[0215] The condition-based mobility configuration includes a first mobility configuration and a second mobility configuration. The first mobility configuration is a configuration for MCG / PCell mobility, and the second mobility configuration is a configuration for SCG / PSCell mobility. The first mobility configuration corresponding to a candidate MCG / PCell and the second mobility configuration corresponding to a candidate SCG / PSCell are associated with each other and stored by the terminal.

[0216] For a detailed description of the content and transmission of the mobility configuration, please refer to the relevant content of the embodiment in Figure 5. The embodiment of this application does not provide a detailed description thereof.

[0217] Step 1104: The terminal associates and stores the first mobility configuration corresponding to the candidate MCG / PCell and the second mobility configuration corresponding to the candidate SCG / PSCell.

[0218] For a detailed description of the storage of mobility settings, please refer to the relevant content of the embodiment in Figure 5. The embodiment of this application does not provide a detailed description thereof.

[0219] Step 1106: In the process of evaluating the execution conditions of the second mobility configuration, the terminal performs measurements based on the information stored in the first variable corresponding to the candidate MCG / PCell associated with the second mobility configuration.

[0220] For a detailed description of the process of evaluating the conditions for performing the second mobility configuration by the terminal, please refer to the relevant content of the embodiment of Figure 5. The embodiment of the present application does not provide a detailed description thereof.

[0221] Step 1108: After the terminal executes CHO and / or CPAC, the terminal processes the first variable and the second variable stored in the terminal.

[0222] For a detailed description of the mobility configuration process, please refer to the relevant content of the embodiment in Figure 5. The embodiment of this application does not provide a detailed description thereof.

[0223] In summary, in the method provided by this embodiment, when a first mobility configuration and a second mobility configuration are jointly configured, the first mobility configuration of a candidate MCG / PCell and the second mobility configuration of a candidate SCG / PSCell corresponding to the candidate MCG / PCell are associated and stored via the terminal, so that the terminal can determine the second mobility configuration corresponding to a different candidate SCG / PSCell without performing a mobility operation for the first mobility configuration. For example, the terminal can determine a CPAC configuration for a different candidate SCG / PSCell without performing CHO. The terminal can simultaneously perform mobility operations for the first mobility configuration and the second mobility configuration.

[0224] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0225] 12 shows a flowchart of a condition-based mobility configuration method provided by an embodiment of the present application, which can be applied to a T-MN. The method includes the following steps:

[0226] Step 1206: Send a condition-based mobility configuration to the S-MN.

[0227] The condition-based mobility configuration is used to perform a mobility operation of the mobility configuration when the terminal determines that the execution condition of the mobility configuration is satisfied. Optionally, the mobility configuration is initiated and configured by the T-MN. Optionally, the mobility configuration is a CPAC configuration. Note that the mobility configuration may be other configurations such as an SCG / PSCell selective activation configuration, and the embodiments of the present application are not limited thereto.

[0228] The mobility configuration includes one or more of an execution condition of the mobility operation, a measurement configuration corresponding to the execution condition of the mobility operation, a candidate MCG / PCell configuration, and a candidate SCG / PSCell configuration, among which the measurement configuration corresponding to the execution condition of the mobility operation, the candidate MCG / PCell configuration, and the candidate SCG / PSCell configuration are used by the terminal to perform measurements and determine whether the measurement results satisfy the execution condition of the mobility operation, thereby determining whether to perform the mobility operation.

[0229] The mobility configuration is used by the S-MN to update the measurement configuration of the terminal and is transferred by the S-MN to the terminal, that is, after receiving the above mobility configuration, the S-MN uses the mobility configuration to update the measurement configuration of the terminal and sends the mobility configuration to the terminal.

[0230] In some embodiments, the T-MN initiates a mobility operation configuration request to determine the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation. Optionally, the mobility operation configuration request initiated by the T-MN can be triggered in one of two ways:

[0231] First Method In some embodiments, the T-MN autonomously initiates the mobility operation configuration request.

[0232] Second Method In some embodiments, the T-MN receives a request message sent from the S-MN. This request message is used to request the T-MN to initiate a mobility operation configuration request. In some embodiments, this request message is also used to request the T-MN to prepare access for an associated terminal and reserve corresponding resources.

[0233] In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is carried in a response message, which is used to respond to the request message sent from the S-MN.

[0234] In some embodiments, the T-MN may receive a notification message sent from the S-MN, which is used to request the T-MN to update the above-mentioned condition-based mobility configuration, or to indicate that a measurement identifier corresponding to an execution condition of a mobility operation based on the condition-based mobility configuration is unavailable, where the measurement identifier is information for identifying the execution condition, and the unavailability of the measurement identifier includes that the measurement identifier is occupied by another measurement identifier.

[0235] For example, the unavailability of a measurement identifier includes the following: the measurement identifier is configured in the terminal, and the corresponding configuration information (execution condition) cannot be updated (for example, the measurement identifier is associated with a mobility configuration corresponding to another candidate cell), in which case the terminal cannot use the mobility configuration initiated by the T-MN.

[0236] In some embodiments, after receiving the above notification message, the T-MN updates the above condition-based mobility configuration and sends the updated condition-based mobility configuration to the S-MN, which then forwards it to the terminal for use.

[0237] Optionally, the notification message includes an available measurement identifier or an unavailable measurement identifier, where the available measurement identifier is an unoccupied measurement identifier and the unavailable measurement identifier is an occupied measurement identifier. In some embodiments, after receiving the notification message, the T-MN can know the available measurement identifier or the unavailable measurement identifier, so that when updating the condition-based mobility configuration, it can configure the configuration corresponding to the unoccupied (available) measurement identifier and provide it to the UE for use.

[0238] In summary, the method provided by this embodiment transmits mobility configuration from the T-MN to the S-MN and forwards it to the UE, so that the UE can know the mobility configuration initiated by the T-MN without accessing the T-MN. For example, the UE can determine CPAC configurations of different candidate SCGs / PSCells without performing CHO. The UE can perform CHO and CPAC simultaneously.

[0239] In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is determined by the T-MN initiating a mobility operation configuration request. As shown in Figure 13, based on the embodiment shown in Figure 12, the method further includes the following steps:

[0240] Step 1204: Initiate a mobility operation configuration request.

[0241] The T-MN initiates a mobility operation configuration request to determine the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation.

[0242] In summary, the method provided by this embodiment enables the T-MN to initiate a mobility operation configuration request, thereby determining the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation, and sending the mobility configuration to the S-MN for forwarding to the terminal, thereby providing a method for the T-MN to determine the mobility configuration.

[0243] In some embodiments, the T-MN autonomously initiates the mobility operation configuration request.

[0244] In some embodiments, the T-MN receives a request message sent from the S-MN to initiate a mobility operation configuration request. As shown in Figure 14, based on the embodiment shown in Figure 13, the method further includes the following steps:

[0245] Step 1202: Receive a request message sent by the S-MN.

[0246] This request message is used to request the T-MN to initiate a mobility operation configuration request.

[0247] In some embodiments, this request message is also used to request the T-MN to prepare access for the associated terminal and reserve corresponding resources. In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is carried in a response message, which is used to respond to the request message sent from the S-MN.

[0248] In summary, the method provided by this embodiment realizes that, based on a request from an S-MN, the T-MN initiates a mobility operation configuration request to determine the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation, and sends the mobility configuration to the S-MN for forwarding to the terminal. A method is provided for the S-MN to trigger the T-MN to determine the mobility configuration, which improves the flexibility of the T-MN in determining the mobility configuration.

[0249] In some embodiments, the T-MN may also receive a notification message sent from the S-MN. As shown in Figure 15, based on the embodiment shown in Figure 12, the method further includes the following steps:

[0250] Step 1208: Receive the notification message sent by the S-MN.

[0251] This notification message is used to request the T-MN to update the above-mentioned condition-based mobility configuration, or to indicate that a measurement identifier corresponding to an execution condition of a mobility operation based on the condition-based mobility configuration is unavailable, where the measurement identifier is information for identifying the execution condition, and the unavailable measurement identifier includes the measurement identifier being occupied by another measurement identifier.

[0252] In some embodiments, after receiving the above notification message, the T-MN updates the above condition-based mobility configuration and sends the updated condition-based mobility configuration to the S-MN, which then forwards it to the terminal for use.

[0253] Optionally, the notification message includes an available measurement identifier or an unavailable measurement identifier, where the available measurement identifier is an unoccupied measurement identifier and the unavailable measurement identifier is an occupied measurement identifier. In some embodiments, after receiving the notification message, the T-MN can know the available measurement identifier or the unavailable measurement identifier, so that when updating the condition-based mobility configuration, it can configure the configuration corresponding to the unoccupied (available) measurement identifier and provide it to the UE for use.

[0254] In summary, the method provided by this embodiment allows the T-MN to know whether the mobility setting initiated by it is available through the notification message sent from the S-MN, so that the T-MN can update the mobility setting if the mobility setting initiated by it is unavailable, and realize the availability of the mobility setting initiated by the T-MN through cooperation between network devices.

[0255] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0256] 16 shows a flowchart of a condition-based mobility configuration method provided by an embodiment of the present application, which can be applied to an S-MN. The method includes the following steps:

[0257] Step 1604: Receive a condition-based mobility configuration sent by the T-MN.

[0258] The condition-based mobility configuration is used to perform a mobility operation of the mobility configuration when the terminal determines that the execution condition of the mobility configuration is satisfied. Optionally, the mobility configuration is initiated and configured by the T-MN. Optionally, the mobility configuration is a CPAC configuration. Note that the mobility configuration may be other configurations such as an SCG / PSCell selective activation configuration, and the embodiments of the present application are not limited thereto.

[0259] For a detailed description of mobility configuration, please refer to the related content of the embodiment in Figure 12. The embodiment of this application does not provide a detailed description thereof.

[0260] Step 1608: Update the measurement configuration of the terminal according to the mobility configuration, and send the mobility configuration to the terminal.

[0261] In summary, the method provided by this embodiment transmits mobility configuration from the T-MN to the S-MN and forwards it to the UE, so that the UE can know the mobility configuration initiated by the T-MN without accessing the T-MN. For example, the UE can determine CPAC configurations of different candidate SCGs / PSCells without performing CHO. The UE can perform CHO and CPAC simultaneously.

[0262] In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is determined by the T-MN initiating a configuration request for mobility operations.

[0263] In some embodiments, the T-MN autonomously initiates the mobility operation configuration request.

[0264] In some embodiments, the T-MN receives a request message sent from the S-MN to initiate a mobility operation configuration request. As shown in Figure 17, based on the embodiment shown in Figure 16, the method further includes the following steps:

[0265] Step 1602: Send a request message to the T-MN.

[0266] This request message is used to request the T-MN to initiate a mobility operation configuration request.

[0267] In some embodiments, this request message is also used to request the T-MN to prepare access for the associated terminal and reserve corresponding resources. In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is carried in a response message, which is used to respond to the request message sent from the S-MN.

[0268] In summary, the method provided by this embodiment realizes that, based on a request from an S-MN, the T-MN initiates a mobility operation configuration request to determine the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation, and sends the mobility configuration to the S-MN for forwarding to the terminal. A method is provided for the S-MN to trigger the T-MN to determine the mobility configuration, which improves the flexibility of the T-MN in determining the mobility configuration.

[0269] In some embodiments, the S-MN may also send a notification message to the T-MN. As shown in Figure 18, based on the embodiment shown in Figure 16, the method further includes the following steps:

[0270] Step 1606: Send a notification message to the T-MN.

[0271] This notification message is used to request the T-MN to update the above-mentioned condition-based mobility configuration, or to indicate that a measurement identifier corresponding to an execution condition of a mobility operation based on the condition-based mobility configuration is unavailable, where the measurement identifier is information for identifying the execution condition, and the unavailable measurement identifier includes the measurement identifier being occupied by another measurement identifier.

[0272] In some embodiments, after receiving the above notification message, the T-MN updates the above condition-based mobility configuration and sends the updated condition-based mobility configuration to the S-MN, which then forwards it to the terminal for use.

[0273] Optionally, the notification message includes an available measurement identifier or an unavailable measurement identifier, where the available measurement identifier is an unoccupied measurement identifier and the unavailable measurement identifier is an occupied measurement identifier. In some embodiments, after receiving the notification message, the T-MN can know the available measurement identifier or the unavailable measurement identifier, so that when updating the condition-based mobility configuration, it can configure the configuration corresponding to the unoccupied (available) measurement identifier and provide it to the UE for use.

[0274] In summary, the method provided by this embodiment allows the T-MN to know whether the mobility setting initiated by it is available through the notification message sent from the S-MN, so that the T-MN can update the mobility setting if the mobility setting initiated by it is unavailable, and realize the availability of the mobility setting initiated by the T-MN through cooperation between network devices.

[0275] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0276] 19 shows a flowchart of a condition-based mobility configuration method provided by an embodiment of the present application, which can be applied to a terminal. The method includes the following steps:

[0277] Step 1902: Receive a condition-based mobility configuration sent by an S-MN.

[0278] The mobility configuration is sent from the T-MN to the S-MN. The mobility configuration includes one or more of an execution condition of the mobility operation, a measurement configuration corresponding to the execution condition of the mobility operation, a candidate MCG / PCell configuration, and a candidate SCG / PSCell configuration, and the mobility configuration is used to update the measurement configuration of the terminal.

[0279] For a detailed description of mobility configuration, please refer to the relevant content of the embodiment in Figure 11. The embodiment of this application does not provide a detailed description thereof.

[0280] In summary, the method provided by this embodiment transmits mobility configuration from the T-MN to the S-MN and forwards it to the UE, so that the UE can know the mobility configuration initiated by the T-MN without accessing the T-MN. For example, the UE can determine CPAC configurations of different candidate SCGs / PSCells without performing CHO. The UE can perform CHO and CPAC simultaneously.

[0281] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments.

[0283] Step 2002: The S-MN sends a request message to the T-MN.

[0284] This request message is used to request the T-MN to initiate a mobility operation configuration request.

[0285] In some embodiments, this request message is also used to request the T-MN to prepare access for the associated terminal and reserve corresponding resources. In some embodiments, the condition-based mobility configuration sent from the T-MN to the S-MN is carried in a response message, which is used to respond to the request message sent from the S-MN.

[0286] Step 2004: The T-MN initiates a mobility operation configuration request.

[0287] The T-MN initiates a mobility operation configuration request to determine the execution conditions of the mobility operation and the measurement configuration corresponding to the execution conditions of the mobility operation.

[0288] Step 2006: The T-MN sends a condition-based mobility configuration to the S-MN.

[0289] The condition-based mobility configuration is used to perform a mobility operation of a mobility configuration when the terminal determines that the execution condition of the mobility configuration is satisfied. Optionally, this mobility configuration is initiated and configured by the T-MN. Optionally, this mobility configuration is a CPAC configuration.

[0290] For a detailed description of mobility configuration, please refer to the related content of the embodiment in Figure 12. The embodiment of this application does not provide a detailed description thereof.

[0291] Step 2008: The S-MN sends a notification message to the T-MN.

[0292] This notification message is used to request the T-MN to update the above-mentioned condition-based mobility configuration, or to indicate that a measurement identifier corresponding to an execution condition of a mobility operation based on the condition-based mobility configuration is unavailable, where the measurement identifier is information for identifying the execution condition, and the unavailable measurement identifier includes the measurement identifier being occupied by another measurement identifier.

[0294] Step 2010: The S-MN updates the measurement configuration of the terminal according to the mobility configuration, and sends the mobility configuration to the terminal.

[0295] In summary, the method provided by this embodiment transmits mobility configuration from the T-MN to the S-MN and forwards it to the UE, so that the UE can know the mobility configuration initiated by the T-MN without accessing the T-MN. For example, the UE can determine CPAC configurations of different candidate SCGs / PSCells without performing CHO. The UE can perform CHO and CPAC simultaneously.

[0296] It should be noted that the above embodiments of the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments to obtain new embodiments. In addition, the order of the method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed.

[0297] This application provides invention point 1 and invention point 2.

[0298] The first invention of this application will be introduced.

[0299] Each candidate MCG / PCell corresponds to one separate Var (Variable) variable for storing the measurement configuration of the candidate MCG / PCell, and one separate Var variable for storing the CPA / CPC configuration corresponding to the candidate MCG / PCell, where CHO in this invention may be MCG selective activation, and CPA / CPC may be SCG selective activation.

[0300] The following illustrates a condition-based mobility configuration method provided by one embodiment of the present application.

[0301] 1. The UE receives a condition-based mobility configuration sent by the network side. The condition-based mobility configuration includes a configuration for MCG / PCell mobility and a configuration for SCG / PSCell mobility. The configuration for SCG mobility in this configuration information is associated with a corresponding candidate MCG. Note that in the following text, MCG may refer to MCG / PCell, and SCG may refer to SCG / PSCell.

[0302] 1.1, the mobility settings of the MCG include one or more of CHO settings, MCG selective activation settings, and L1 / L2 triggered MCG mobility (LTM-MCG).

[0303] 1.2. The mobility settings of the SCG include one or more of CPA settings, CPC settings, SCG selective activation settings, and L1 / L2 triggered SCG mobility (LTM-SCG).

[0304] 1.3. The settings for CHO, CPA, CPC, MCG selective activation, and SCG selective activation include one or more of the following information: 1.3.1, Configuration Identifier, 1.3.2, Execution Conditions, 1.3.3, the corresponding settings for the corresponding candidate MCG and / or SCG; 1.3.4, instruction information indicating the purpose of this setting. For example, the purpose may be one or more of CHO, CPA, CPC, MCG selective activation, and SCG selective activation.

[0305] 1.4. The configuration information corresponding to the candidate MCG includes measurement configuration information corresponding to the candidate MCG.

[0306] 1.5. Illustratively, the configuration information corresponding to the candidate MCG includes the mobility configuration of the SCG.

[0307] For example, a UE receives condition-based mobility configuration information, which includes configuration information for a CHO and configuration information for one or more associated CPAs / CPCs. The configuration information for the CHO includes an execution condition for the CHO and configuration information for a candidate MCG. The configuration information for the candidate MCG includes configuration information for one or more CPCs / CPAs and configuration information for a subsequent MCG. The subsequent MCG refers to an MCG to which the UE may switch when switching again after switching to the candidate MCG.

[0308] 2. Based on 1, when the UE receives a joint mobility configuration including a configuration for MCG mobility and a configuration for SCG mobility sent from the network side, the UE stores the received mobility configuration information.

[0309] 3. Based on 2, the UE stores measurement configurations corresponding to the candidate MCGs, and each candidate MCG corresponds to one separate first variable (this variable is a UE variable, also referred to as Var variable) for storing measurement configurations. This first variable is used to store measurement configuration information corresponding to the candidate MCGs sent from the network side to the UE. Among them, the first variable may be a measurement configuration variable (VarMeasConfig).

[0310] 3.1. Based on the measurement configuration corresponding to the UE's current serving MCG (the current cumulative configuration stored in the first variable storing the serving MCG measurement configuration), generate a measurement configuration corresponding to the candidate MCG (a complete measurement configuration corresponding to this candidate MCG) according to the measurement configuration information (incremental configuration) included in the configuration corresponding to the candidate MCG.

[0311] For example, 3.1.1. The configuration corresponding to the candidate MCG includes measurement configuration information (incremental configuration), which includes one or more pieces of information such as a configuration addition / change table, a configuration deletion table, measurement quantity configuration, measurement configuration (s-MeasureConfig) (e.g., measurement start threshold), and measurement gap (Gap) configuration. 3.1.2. The first variable storing the measurement settings includes one or more pieces of information such as a setting table, a measurement quantity setting, a measurement setting (s-MeasureConfig) (e.g., a measurement start threshold), and a measurement Gap setting.

[0312] Of these, the setting addition / change table (...AddModList) and the setting deletion table (...RemoveList) are: Measurement object removal table (measObjectToRemoveList), Measurement object add / modify table (measObjectToAddModList), Report configuration removal table (reportConfigToRemoveList), Report Config Add Modification Table (reportConfigToAddModList), Measurement identifier removal table (measIdToRemoveList), Measurement identifier add / change table (measIdToAddModList), It may be one or more or all of the following:

[0313] Among these, the configuration tables include one or more of a measurement identifier table (measIdList), a measurement object table (measObjectList), and a report configuration table (reportConfigList).

[0314] Among these, specific procedures for generating a measurement configuration corresponding to a candidate MCG based on the measurement configuration of the current serving MCG and the incremental measurement configuration information included in the configuration corresponding to the candidate MCG may be as follows: the UE adds or modifies the configuration corresponding to the current serving MCG based on a configuration addition / modification table included in the incremental measurement configuration of the candidate MCG to obtain the configuration corresponding to the candidate MCG; the UE deletes the configuration corresponding to the current serving MCG based on a configuration deletion table included in the incremental measurement configuration of the candidate MCG to obtain the configuration corresponding to the candidate MCG; updates the configuration corresponding to the current serving MCG using the measurement quantity configuration, s-MeasureConfig (measurement start threshold), and measurement gap configuration in the incremental configuration information (if any), obtains the configuration corresponding to the candidate MCG, and stores it via a first variable corresponding to the candidate MCG.

[0315] 3.2. Based on storing the measurement setting information (incremental setting) included in the setting corresponding to the candidate MCG, store it via a first variable corresponding to this candidate MCG.

[0316] According to 4 and 2, the UE stores the configuration for mobility of the SCG, and each candidate MCG corresponds to one separate second variable (this variable is a UE variable, also called Var variable) for storing the mobility configuration, which is used to store the corresponding mobility configuration of one or more candidate SCGs corresponding to the candidate MCG.

[0317] Of these, the second variable may be a conditional reset variable (VarConditionalReconfig).

[0318] Among these, the second variable includes a field, a conditional reconfiguration table (condReconfigList), for representing mobility configuration, and this field is represented by a conditional reconfiguration add-mod table (CondReconfigToAddModList).

[0319] 4.1. For example, for a joint mobility configuration, if the configuration corresponding to a candidate MCG included in the mobility configuration of a candidate MCG includes the mobility configuration of one or more candidate SCGs associated with the candidate MCG, then in response to the UE receiving this joint mobility configuration, the UE reads the configuration corresponding to the candidate MCG from the mobility configuration of the candidate MCG and stores the mobility configuration of one or more candidate SCGs included therein using a second variable corresponding to the candidate MCG. For example, the joint mobility configuration is CHO+CPC, and the candidate MCG of each CHO corresponds to one second variable, and stores the CPC configuration of one or more (all) SCGs corresponding to the candidate MCG to which the CHO is configured via the second variable.

[0320] 5. Based on 1-4 above, for SCG mobility triggered by conditions (including CPA / CPC / SCG selective activation), in the process of evaluating the execution conditions of SCG mobility, the UE performs measurements based on the measurement configuration stored in the first variable corresponding to the candidate MCG associated with the mobility configuration of this SCG, and evaluates whether the event corresponding to this execution condition is met.

[0321] Illustratively, when performing a CPAC event evaluation, the UE performs measurements based on the measurement configuration stored in the first variable corresponding to the candidate MCG associated with this CPAC, and evaluates whether the CPAC event is satisfied.

[0322] In the case of the method of generating the first variable described in 5.1 and 3.1, the UE can perform measurements based only on the measurement configuration stored in the first variable corresponding to the candidate MCG and evaluate whether an event corresponding to the execution condition corresponding to the mobility configuration of the candidate SCG associated with this candidate MCG is satisfied.

[0323] In the case of the method of generating the first variable described in 5.2 and 3.2, the UE can perform measurements on the measurement configuration corresponding to the candidate MCG based on the measurement configuration stored in the first variable corresponding to the candidate MCG and the measurement configuration corresponding to the current serving MCG, and evaluate whether an event corresponding to the execution condition corresponding to the mobility configuration of the candidate SCG associated with the candidate MCG is satisfied.

[0324] 6. Based on 1-4 above, if the joint arrangement is a joint arrangement between CHO and CPAC 6.1: After the UE performs CHO and CPAC, the UE deletes all entries in the Var variable (i.e., the second variable) that stores all conditional reconfiguration settings (i.e., clears the second variables corresponding to each candidate MCG and the second variable corresponding to the serving MCG). Updates the Var variable that stores the measurement settings corresponding to the candidate MCG to be accessed to the first variable of the serving MCG (based on 3.1). Or, based on the first variable that stores the measurement settings corresponding to the candidate MCG to be accessed, updates the first variable of the serving MCG to the first variable of the newly accessed serving MCG (based on 3.2). Clears the Var variables (first variables) that store the measurement settings corresponding to other candidate MCGs. 6.2. In the joint configuration of CHO and CPAC, if the UE only performs CHO and does not perform CPAC, it can follow the procedure in 6.1. 6.3. In the joint configuration of CHO and CPAC, if the UE performs only CHO and does not perform CPAC, the UE deletes all entries in the Var variable (second variable) that stores the conditional reconfiguration configuration corresponding to other candidate MCGs (i.e., clears the second variables corresponding to other candidate MCGs and the second variable corresponding to the serving MCG). The UE updates the second variable corresponding to the candidate MCG to be accessed to the second variable of the serving MCG.

[0325] Each section (identified by the number x) in the above embodiments can be implemented as an independent embodiment, and the contents within each section (identified by the number xy or xyz) can be implemented as a possible implementation method for the corresponding embodiment. The second invention of this application will now be introduced.

[0326] The T-MN sends measurement configurations related to the CPAC execution conditions to the S-MN, and the S-MN can directly forward the corresponding measurement configurations to the UE. The S-MN adjusts the measurement configurations of each T-MN based on this measurement configuration information, then updates the UE's measurement configuration and sends the CHO+CPAC measurement configuration to the UE. If the measurement identifier corresponding to the CPAC execution condition is occupied, the S-MN notifies the T-MN and requests the T-MN to update the CPAC execution condition. By sending available measurement identifiers to the T-MN, the S-MN avoids setting unavailable execution conditions and measurement configurations.

[0327] The following describes how to set up a CPAC provided by one embodiment of the present application.

[0328] 1. The source MN (S-MN) sends a request message (for mobility configuration request) to the target MN (T-MN), requesting it to prepare access for associated UEs and reserve corresponding resources.

[0329] 2. The T-MN initiates a configuration request for one or more CPACs based on a request message from the source MN or autonomously, and determines the execution conditions of the CPACs and the measurement configurations corresponding to the execution conditions of the CPACs.

[0330] 3. The T-MN sends measurement configuration information corresponding to the execution conditions, the execution conditions of the CPAC, the configuration information of the candidate MCG, and the configuration information of the candidate SCG to the S-MN, for example, through a response message, and this information can be included in the mobility configuration information.

[0331] 4. S-MN is 3 2. Update the measurement configuration of the UE based on the information described in 2. and forward the mobility configuration information sent from the T-MN to the S-MN to the UE.

[0332] 5. 4 In the above, if the S-MN determines that the measurement identifier corresponding to the CPAC execution condition sent from the T-MN is unavailable (for example, this measurement identifier is configured in the UE and associated with the mobility configuration corresponding to another candidate cell, and the corresponding configuration information cannot be updated), the S-MN notifies the T-MN and requests the T-MN to update the CPAC execution condition, such as updating the measurement identifier corresponding to the execution condition. Among these, whether the measurement identifier is available can be determined based on the implementation algorithm of the S-MN.

[0333] Based on 6 and 5, the S-MN can include an available measurement identifier in the notification message and send it to the T-MN, thereby avoiding the CPAC execution condition set by the T-MN being associated with an unavailable measurement identifier.

[0334] Note that each section (identified by the number x) of the above embodiments can be implemented as an independent embodiment, and the contents of each section can be implemented as a possible implementation method for the corresponding embodiment.

[0335] It should be noted that the above embodiments in the present application can be consistently combined with other embodiments, steps in other embodiments, and specific implementation methods of steps in other embodiments. The order of method steps provided by the embodiments of the present application can be adjusted as appropriate, and steps can be added or removed as needed. Modifications within the technical scope disclosed in the present application can be easily conceived by those skilled in the art, and all of them are within the scope of protection of the present application, so they will not be described in detail here.
