[0184] FIG1a is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0185] As shown in FIG. 1 a , a communication system 100 includes a terminal 101 and a network device 102 .

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0200] In some embodiments, the information processing method shown in the embodiments of the present disclosure may be applied to a communication system using dual connectivity technology, which includes the following:

[0201] The first is Multi-Radio Dual Connectivity (MR-DC).

[0202] MR-DC is a generalized dual connectivity within the evolved universal terrestrial radio access (E-UTRA) of the UMTS. In this system, the UE can utilize radio resources provided by two different resource scheduling units located on two different next-generation radio access network (NG-RAN) nodes, connected via a non-ideal backhaul: one providing New Radio (NR) access and the other providing E-UTRA or NR access. The base station of the primary cell can be a master node (MN), and the base station of the secondary cell can be a secondary node (SN); the master node and the secondary node are connected via a network interface, with at least one of the master nodes connected to the core network.

[0203] The second type is MR-DC based on the Evolved Packet Core (EPC).

[0204] Refer to Figure 1b, which shows an architecture diagram of the Evolved Universal Terrestrial Radio Access Network (E-UTRA-NR) Dual Connectivity (EN-DC). E-UTRAN supports MR-DC through E-UTRA-NR Dual Connectivity (EN-DC), where the UE connects to an eNB (eNode B) acting as a master node (MN) and an en-gNB (en-gNB) acting as a secondary node (SN). The eNB connects to the EPC (Core Network) via the S1 interface and to the en-gNB via the X2 interface. The en-gNB can also connect to the EPC (Core Network) via the S1-U interface and to other en-gNBs via the X2-U interface.

[0205] The core network equipment of the EPC may include: a Mobility Management Entity (MME) and / or a Serving Gateway (S-GW).

[0206] The third type is the MR-DC of the fifth-generation mobile communication core network (5th Generation Core, 5GC).

[0207] 5GC supports the following dual connections:

[0208] 1) Evolved Universal Terrestrial Radio Access (E-UTRA) - New Radio (NR) and Next Generation RAN E-UTRA New Radio - Dual Connectivity (NGEN-DC) Dual Connectivity:

[0209] The 5G radio access network NG-RAN supports NG-RAN E-UTRA-NR dual connectivity (NGEN-DC), in which the UE is connected to the ng-eNB as the primary node (MN) and the gNB as the secondary node (SN). The base station ng-eNB is connected to the 5GC, and the base station gNB is connected to the base station ng-eNB through the Xn interface.

[0210] 2) Dual connectivity of the New Radio-Evolution Universal mobile telecommunications system Terrestrial Radio Access Network (NR-E-UTRA):

[0211] NG-RAN supports NR-E-UTRA Dual Connectivity (NE-DC), where the UE is connected to the gNB acting as the mobile node and the ng-eNB acting as the secondary node (SN). The gNB is connected to the 5GC, and the ng-eNB is connected to the gNB via the Xn interface.

[0212] 3) NR-NR dual connectivity:

[0213] Referring to Figure 1c, which is a schematic diagram of the NR-DC architecture, NG-RAN supports NR-NR Dual Connectivity (NR-DC), in which the UE is connected to a gNB acting as a mobile node (MN) and another gNB acting as a secondary node (SN). The primary gNB is connected to the 5GC via the NG interface, and the two gNBs are connected via the Xn interface. The secondary gNB can also be connected to the 5GC via the NG-U interface. In addition, NR-DC can also be used for UEs to access a single gNB, which acts as both a mobile node and a secondary node (SN), and is configured with both a primary cell group (MCG) and a secondary cell group (SCG).

[0214] In some embodiments, under dual connectivity, a user equipment (UE) can access two cells or two cell groups at the same time. For example, accessing the primary cell (PCell) and the secondary cell (SCell) at the same time, or accessing the master cell group (MCG) and the secondary cell group (SCG) at the same time. The MCG includes multiple cells, one of which is used to initiate initial access, and this cell is called the PCell. As the name suggests, the PCell is the most important cell in the MCG. The other cells in the MCG except the PCell are SCells. The PCell in the MCG and the SCell in the MCG are combined through carrier aggregation (CA) to improve the transmission rate and meet the user's requirements for the rate.

[0215] In some embodiments, the primary cell in an MCG (Master Cell Group) can be abbreviated as PCell, and the secondary cell can be abbreviated as SCell. The primary and secondary cells in an SCG (Secondary Cell Group) can be abbreviated as PSCell. Typically, much of the UE's control signaling is sent only on the PCell or PSCell. In some embodiments, the concept of a special (Primary) cell (sPcell) is proposed; the sPcell may include: the PCell and / or the PSCell.

[0216] As shown in Figure 1d, Figure 1d is a schematic diagram of a primary cell group and a secondary cell group. When a UE supports dual connectivity, multi-connectivity, or carrier aggregation, the UE's serving cell may include a primary cell and a secondary cell; and the UE's serving cell group may include: a primary cell group and a secondary cell group.

[0217] In one embodiment, in a 5G system, a UE may perform mobility operations based on network preconfigured conditions and a preconfigured cell or cell group corresponding to the condition. When the UE meets the preconfigured condition (e.g., a specific measurement event), the UE changes the serving cell or cell group to the preconfigured cell or cell group.

[0218] The mobility process based on conditional triggering may include:

[0219] Conditional PSCell Addition (CPA);

[0220] Conditional PSCell Change (CPC)

[0221] The UE can also change the special cell or special cell group configuration according to network instructions after meeting preconfigured conditions. For example, the UE's primary cell (PCell) configuration can be changed from candidate cell or candidate cell group configuration-1 to candidate cell or cell group configuration-2. A candidate cell is a candidate cell that the UE can access as a serving cell. A candidate cell group can be a group of candidate cells that the UE can access as a serving cell.

[0222] However, a UE with CPC / CPA configuration must delete the CPC / CPA configuration when completing random access to the target primary / secondary cell. That is, the UE switches the serving cell to the target primary / secondary cell based on CPC or CPA through random access.

[0223] Therefore, if the network does not reconfigure and reinitialize CPC / CPA, the UE will not continue to perform CPC / CPA. This will increase the latency of handovers or SCG changes and increase signaling overhead. In particular, in FR2 scenarios, frequent changes in cell groups (CGs) will increase the latency of handovers or SCG changes and increase signaling overhead. CGs include MCGs and SCGs.

[0224] In R18 mobility enhancement, selective activation of cell groups in MR-DC is proposed. Selective activation of cell groups can also be called cell group activation. After triggering a change or addition of a cell group or PSCell, the UE does not delete the conditional reconfiguration configuration (CPAC configuration). Without RRC reconfiguration or reinitialization of the cell group selective activation configuration, the original CPAC configuration can continue to be used for subsequent CPAC (subsequent CPAC). Supporting subsequent CPAC can effectively reduce signaling overhead and shorten interruption time.

[0225] It should be noted that subsequent CPAC can be understood as: the process of performing the operation of adding or changing candidate primary and secondary cells based on the configuration of CPC or CPA pre-configured for the candidate primary and secondary cells without reconfiguring and restarting CPC or CPA.

[0226] The configuration of a subsequent CPAC includes but is not limited to at least one of the following: a configuration identifier, an execution condition, and the configuration of the corresponding candidate target cell (or cell group).

[0227] The network side can configure multiple subsequent CPAC (subsequent CPAC) configurations and reference configurations for the UE at the same time.

[0228] Wherein, the configuration identifier is an ID indicating the relevant configuration;

[0229] The execution condition is the triggering of mobility operation (conditions that the UE needs to meet to trigger CPAC);

[0230] The configuration of the corresponding candidate target cell (or cell group) is the candidate configuration corresponding to the target cell accessed when the UE triggers the mobility operation. This configuration can be represented by RRC reconfiguration (RRCReconfiguration).

[0231] The reference configuration is: the reference configuration corresponding to the candidate target configuration. The candidate target configuration is an incremental configuration of the reference configuration. A complete configuration can be generated based on the candidate target configuration and the reference configuration. This configuration can be represented by RRC reconfiguration (RRCReconfiguration). The UE will apply the complete configuration when executing CPAC. The reference configuration can be a specific configuration generated by the network or the current configuration of the UE. The reference configuration is only required for subsequent CPAC configurations.

[0232] For CPAC in Rel-16 and Rel-17, the CPAC configuration does not include a reference configuration and only includes a configuration identifier, execution conditions, and the configuration of the corresponding candidate target cell (or cell group). The target cell accessed when the UE triggers a mobility operation directly applies the configuration of the candidate target cell (or cell group).

[0233] In subsequent CPACs, the network device can provide the terminal with candidate cell / cell group configurations. These candidate cell / cell group configurations can be applied multiple times without the network device having to re-provision the cell / cell group configurations. That is, for subsequent CPACs, even after the terminal applies a new cell group configuration and / or connects to a new cell, the UE does not delete the original subsequent CPAC configuration.

[0234] In R17 CPAC, UE can support CPC initiated by the master node and CPC initiated by the secondary node. The triggering conditions of CPC can be, among which CPC initiated by the MN can be configured with condition event (CondEvent) A4, and CPC initiated by the SN can be configured with condition event A5.

[0235] The conditional event (CondEvent) A3 is: the conditional reconfiguration candidate (cell) becomes an amount of offset better than PCell / PSCell.

[0236] Conditional event (CondEvent) A4 is: a conditional reconfiguration candidate (cell) becomes better than an absolute threshold.

[0237] Conditional event (CondEvent) A5 is: PCell / PSCell becomes worse than absolute threshold 1, and 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).

[0238] For subsequent CPAC in R18, both MN-initiated and SN-initiated subsequent CPAC are supported.

[0239] The subsequent CPAC initiated by the MN may include the following operations:

[0240] For MN initiated inter-SN SCG selective activation, source MN generates the execution conditions for the initial CPAC.

[0241] Subsequent CPC execution can also have the following alternative options:

[0242] Option 1: Source MN generates the execution conditions for all subsequent CPCs.

[0243] Option 2: Candidate SN may generate execution conditions for subsequent CPC.

[0244] The subsequent CPAC for SN startup can be as follows:

[0245] For SN initiated inter-SN SCG selective activation, source SN generates the execution conditions for the initial CPC;

[0246] For SN-initiated SCG selective activation, candidate SN generates execution conditions for subsequent CPC.

[0247] As shown in Figure 1e, Figure 1e is a schematic diagram of a CPC process initiated by an MN according to an embodiment of the present disclosure, which illustrates a CPC process for inter-SN CPC configuration and execution initiated by an MN.

[0248] As shown in Figure 1f, Figure 1f is a schematic diagram of a CPC process initiated by an SN according to an embodiment of the present disclosure, which illustrates a CPC process initiated by an SN for inter-SN CPC configuration and inter-SN CPC execution.

[0249] The SN modification process may also be initiated by the source SN. The source SN initiating the SN modification process may include at least one of the following:

[0250] To modify the cross-SN CPC configuration initiated by the current SN, the source SN initiates the SN modification;

[0251] The source SN triggers the deletion of the candidate node by canceling all configured PScells on the candidate SN and / or releasing the UE context on the candidate SN.

[0252] In some embodiments, to support subsequent CPAC initiated by an R18 MN / SN, the candidate CN generates execution conditions for the candidate CPC. In some cases, the candidate SN is unaware of the candidate PSCells currently configured by the UE and the candidate PSCells that other candidate SNs are preparing to configure. If the candidate SN is unaware of the candidate PSCells that the UE has configured and is about to configure for subsequent CPAC, the candidate SN cannot generate execution conditions for these candidate PSCells for subsequent CPAC.

[0253] In some embodiments, the MN will send the source SN and / or MN recommends that the candidate SN prepare candidate PSCells for CPC to the candidate SN, but the MN will not inform the candidate SN which candidate PSCells that the UE has currently configured and is preparing to configure to support subsequent CPAC.

[0254] FIG2a is an interactive diagram of an information processing method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to an information processing method for a communication system 100, the method comprising:

[0255] Step S2101: The first node sends a first message to the second node.

[0256] In some embodiments, the second node receives a first message sent by the first node.

[0257] In some embodiments, the first node may include a master node; the master node may be an access network device corresponding to a primary cell or a primary cell group.

[0258] It is understandable that the first node is associated with the primary cell of the terminal. It is understandable that the primary cell of the terminal is the cell of the first node.

[0259] In some embodiments, the second node may include a candidate secondary node (C-SN); the candidate secondary node may be a base station corresponding to a candidate primary and secondary cell. The candidate secondary node may be an alternative node to the secondary node of the terminal. The secondary node may provide a candidate secondary cell for the terminal. The candidate secondary cell may subsequently be referred to as the secondary cell of the terminal.

[0260] It is understood that the second node is associated with one or more candidate primary and secondary cells of the terminal. It is understood that one or more cells of the second node can serve as candidate primary and secondary cells of the terminal. The candidate primary and secondary cells may subsequently serve as the primary and secondary cells of the terminal.

[0261] In some embodiments, the terminal may be a terminal supporting dual connectivity, multiple connectivity or carrier aggregation.

[0262] In some embodiments, the first node sends a first message to a plurality of candidate secondary nodes of the terminal.

[0263] In some embodiments, the first message may carry indication information.

[0264] In some embodiments, the indication information is used by the second node to configure execution conditions for performing the mobility operation.

[0265] In some embodiments, the first message is used to add a secondary node of the terminal.

[0266] It should be noted that the addition of the terminal's secondary node is initiated by the primary node, and the secondary node addition process is used to establish the terminal's context on the secondary node so that the secondary node can provide resources for the terminal.

[0267] In some embodiments, the first message may include: a secondary node addition request (SN Addition Request) message.

[0268] It should be noted that the first node can reuse the existing secondary node addition request message to send the indication information to the second node. On the one hand, the second node can obtain one or more candidate primary and secondary cells for mobility operations indicated by the indication information based on the indication information, so that the second node can configure the execution conditions for the mobility operation for the candidate primary and secondary cells. On the other hand, it can reduce signaling overhead.

[0269] In some embodiments, the first message may be an Xn message.

[0270] It should be noted that the first node and the second node are connected via an Xn interface, and the first node sends the first message to the second node via the Xn interface.

[0271] In some embodiments, the Xn message may carry one or more parameters indicating one or more candidate primary and secondary cells for performing mobility operations.

[0272] Exemplarily, the Xn message may carry a first parameter for indicating one or more candidate primary and secondary cells configured for the terminal and one or more candidate primary and secondary cells to be configured for the terminal.

[0273] As another example, the Xn message may carry at least one of the following:

[0274] The second parameter is used to indicate one or more candidate primary and secondary cells configured by the terminal;

[0275] The third parameter is used to indicate one or more candidate primary and secondary cells to be configured for the terminal.

[0276] In some embodiments, the above parameters may include at least one of the following:

[0277] Cell identification information of candidate primary and secondary cells;

[0278] Node identifiers of associated nodes of candidate primary and secondary cells;

[0279] Cell measurement result information of candidate primary and secondary cells.

[0280] Exemplarily, the parameters in the Xn message may include an information list of a group of candidate secondary nodes; wherein the information corresponding to each candidate secondary node in the information list includes one or more candidate primary and secondary cells corresponding to the candidate secondary node.

[0281] In some embodiments, the Xn message may carry one or more indication bits, and the candidate primary and secondary cells of the terminal may be indicated through different bit values ​​of the one or more indication bits.

[0282] In some embodiments, the Xn message includes an inter-node Radio Resource Control (RRC) message container.

[0283] It should be noted that the Xn message may include one or more first message containers. Each candidate secondary node corresponds to a first message container; the first message container may be an inter-node RRC message container. It is understood that the first message container can be used to carry inter-node RRC messages.

[0284] It is worth noting that the first message container included in the Xn message is not limited to the above-mentioned inter-node RRC message container, and may also include other message containers related to Xn message transmission or other RRC messages or information-related content.

[0285] In some embodiments, the indication information is carried in an inter-node radio resource control RRC message container.

[0286] In some embodiments, the inter-node RRC message container may carry one or more indication bits, and the candidate primary and secondary cells of the terminal may be indicated through different bit values ​​of the one or more indication bits.

[0287] In some embodiments, the inter-node radio resource control RRC message container further includes: cell group CG-configuration information ConfigInfo.

[0288] It is understandable that the first message container in the Xn message can be used to carry CG-ConfigInfo. The indication information is carried in CG-ConfigInfo.

[0289] It should be noted that CG-ConfigInfo is used to carry configuration information related to a cell or a cell group.

[0367] For example, the reserved information field in the first message can be used to implicitly determine the configuration status of the mobility operation by determining whether the reserved information field carries the configuration identifier of the mobility operation. It should be noted that a configuration identifier is an identifier corresponding to a configured mobility operation; a mobility operation to be configured for the terminal does not have a corresponding configuration identifier. Therefore, the configuration status of the mobility operation can be determined by determining whether the reserved information field in the first message carries the configuration identifier of the mobility operation.

It is understandable that the confirmation message carries the execution conditions generated by the second node.

[0378] In some other embodiments, the confirmation message may include: an event type and / or a parameter value corresponding to the execution condition of the mobility operation.

[0379] In some embodiments, the event type and / or parameter value corresponding to the execution condition is used by the first node and / or the fourth node to generate the execution condition for the mobility operation.

[0380] In some embodiments, the first node may generate an execution condition for the mobility operation associated with the second node according to an event type and / or parameter value corresponding to the execution condition carried in the confirmation message.

[0391] It should be noted that the parameter value can be understood as the parameter value of the event corresponding to the execution condition, for example, A3 offset; A4 threshold value, A5 threshold value 1, A5 threshold value 2, etc.

[0392] In some embodiments, the confirmation message may further include: measurement configurations of one or more candidate primary and secondary cells configured by the second node.

[0396] Exemplarily, the measurement identifier carried in the confirmation message indicates that the measurement configuration corresponding to the execution condition is the measurement configuration of the candidate secondary node, indicating that the execution condition is generated based on the measurement configuration of the candidate secondary node.

[0397] As another example, the measurement identifier carried in the confirmation message indicates that the measurement configuration corresponding to the execution condition is the measurement configuration of the source slave node, indicating that the execution condition is generated based on the measurement configuration of the source slave node.

[0399] Step S2103: the first node determines an execution condition of the mobility operation and / or the second node configures a measurement configuration of one or more candidate primary and secondary cells associated with the execution condition.

[0400] In some embodiments, the first node determines an execution condition of the mobility operation according to the confirmation message and / or the second node configures a measurement configuration of one or more candidate primary and secondary cells associated with the execution condition.

[0401] In some embodiments, the first node may determine the execution conditions of the mobility operations configured by the multiple candidate secondary nodes and the measurement configuration of one or more candidate primary and secondary cells configured by each candidate secondary node according to the confirmation messages sent by the multiple candidate secondary nodes.

[0402] In some embodiments, the first node sends configuration information to the terminal.

[0403] In some embodiments, the configuration information indicates an execution condition of the mobility operation and / or a measurement configuration of one or more candidate primary and secondary cells configured by the candidate secondary node.

It is understood that when the first node sends a first message carrying the first information to the second node, the second node may refuse to configure the candidate primary and secondary cells; if the first node does not receive a confirmation message for the first message, the first node does not need to determine the execution conditions and / or measurement configuration for the mobility operation.

[0512] A candidate primary and secondary cell associated with a third node configured for the terminal has been determined, where the third node is different from the second node.

[0513] In some embodiments, all candidate primary and secondary cells determined to be configured for the terminal may include:

[0514] The candidate primary and secondary cells associated with the second node and configured for the terminal have been determined, and the candidate primary and secondary cells associated with the third node and configured for the terminal have been determined.

[0515] In some embodiments, the third node may include a candidate secondary node; the candidate secondary node may be a base station corresponding to a candidate primary and secondary cell. Furthermore, the third node is different from the second node.

[0530] In some embodiments, the seventh information is used to indicate at least one of the following:

[0531] The mobility operations configured for the terminal;

[0532] Prepare mobility operations configured for the terminal.

[0533] It should be noted that the mobility operation configured for the terminal can be understood as the candidate primary and secondary cells corresponding to the mobility operation being the configured candidate primary and secondary cells; the candidate primary and secondary cells corresponding to the mobility operation can be understood as the candidate primary and secondary cells prepared to be configured for the terminal.

[0534] It is worth noting that the embodiment of the present disclosure explicitly indicates the configuration state of the mobility operation through the seventh information, so that the second node can quickly and accurately learn the configuration state of the mobility operation based on the seventh information.

[0535] In other embodiments, the first node may indicate the configuration status of the mobility operation to the second node in an implicit manner.

[0536] For example, the reserved information field in the first message can be used to implicitly determine the configuration status of the mobility operation by determining whether the reserved information field carries the configuration identifier of the mobility operation. It should be noted that a configuration identifier is an identifier corresponding to a configured mobility operation; a mobility operation to be configured for the terminal does not have a corresponding configuration identifier. Therefore, the configuration status of the mobility operation can be determined by determining whether the reserved information field in the first message carries the configuration identifier of the mobility operation.

[0538] The first node initiates an operation of adding or changing the second node, and the first node sends a second message to the second node.

[0546] In some embodiments, the confirmation message is used to determine the execution condition of the mobility operation.

[0547] It should be noted that the execution conditions of the mobility operation can be understood as the conditions that the terminal needs to meet to add or change the candidate primary and secondary cells when the candidate primary and secondary cells configured by the second node are used as the service cells of the terminal; each candidate primary and secondary cell associated with the third node corresponds to an execution condition.

[0548] The execution conditions corresponding to any candidate primary and secondary cell associated with the third node can be understood as the conditions that need to be met when the terminal switches from the candidate primary and secondary cell configured by the second node to the candidate primary and secondary cell associated with the third node when the candidate primary and secondary cell configured by the second node is used as the service cell of the terminal.

[0549] In some embodiments, the confirmation message may include: execution conditions of the mobility operation.

[0550] It should be noted that, after receiving the second information in the second message, the second node may configure execution conditions for the terminal to perform the mobility operation based on one or more candidate primary and secondary cells in the second candidate primary and secondary cell set indicated by the second information. It is understandable that the confirmation message carries the execution conditions generated by the second node.

[0551] In some other embodiments, the confirmation message may include: an event type and / or a parameter value corresponding to the execution condition of the mobility operation.

[0554] In other embodiments, when the fourth node initiates the mobility operation, the first node may forward the event type and / or parameter value corresponding to the execution condition carried in the confirmation message to the fourth node, and the fourth node generates the execution condition of the mobility operation associated with the second node.

[0555] In some embodiments, the event type of the conditional event corresponding to the execution condition may include at least one of the following:

[0556] Conditional event A3;

[0568] It should be noted that the measurement configuration of one or more candidate primary and secondary cells configured by the second node is based on the measurement configuration of the primary node and / or the secondary node.

[0569] In some embodiments, the confirmation message may include a measurement identifier, which is used to indicate the measurement configuration corresponding to the execution condition.

[0570] Exemplarily, the measurement identifier carried in the confirmation message indicates that the measurement configuration corresponding to the execution condition is the measurement configuration of the candidate secondary node, indicating that the execution condition is generated based on the measurement configuration of the candidate secondary node.

[0571] As another example, the measurement identifier carried in the confirmation message indicates that the measurement configuration corresponding to the execution condition is the measurement configuration of the source slave node, indicating that the execution condition is generated based on the measurement configuration of the source slave node.

[0572] As another example, the measurement identifier carried in the confirmation message indicates that the measurement configuration corresponding to the execution condition is the measurement configuration of the source master node, indicating that the execution condition is generated based on the measurement configuration of the source master node.

[0573] Step S2205: the first node determines an execution condition of the mobility operation and / or the second node configures a measurement configuration of one or more candidate primary and secondary cells associated with the execution condition.

[0574] In some embodiments, the optional implementation of step S2205 can refer to the optional implementation of step S2103 in Figure 2a and other related parts of the embodiment involved in Figure 2a, which will not be repeated here.

For example, step S2201 can be implemented as an independent embodiment, for example, step S2201 combined with steps S2202 and S2203 can be implemented as an independent embodiment, for example, step S2201 combined with steps S2202 and S2205 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0576] In some embodiments, steps S2202, S2203, 2204, and 2205 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understood that upon receiving the first message, the second node may refuse to configure the candidate primary and secondary cells, or upon receiving the second message, the second node may refuse to modify the configuration of the candidate primary and secondary cells; if the first node does not receive the confirmation message, the first node does not need to perform subsequent processing.

[0577] In some embodiments, step S2203 and step S2204 are optional, and one or more of these steps may be omitted or replaced in different embodiments. It is understandable that when the first node can send a first message carrying the first information to the second node, the first node can determine the execution condition and the measurement configuration of one or more candidate primary and secondary cells configured by the second node based on the confirmation message of the first message returned by the second node, without the first node having to send a second message to the second node, nor the second node having to return a confirmation message of the second message.

[1095] Example 9: The execution condition in Example 8 is generated by the C-SN, and the execution condition can be one or more of the following:

[1096] 9.1, an execution condition is generated with reference to the measurement configuration of the C-SN, where the execution condition corresponds to the measurement identifier corresponding to the measurement configuration of the C-SN.

[1097] 9.2, an execution condition is generated with reference to the S-SN measurement configuration, where the execution condition corresponds to the measurement identifier corresponding to the S-SN measurement configuration.

[1098] 9.3, an execution condition is generated with reference to the measurement configuration of the S-MN, where the execution condition corresponds to the measurement identifier corresponding to the measurement configuration of the S-MN.

[1099] Example 10: C-SN generates the type of event and / or corresponding parameters corresponding to each execution condition, wherein the parameters include but are not limited to one or more of A3 offset, A4 threshold, A5 threshold 1, A5 threshold 2, trigger time TTT, and hysteresis value.

[1100] Based on the event type and / or corresponding parameters of the execution condition provided by the C-SN, the MN can generate the execution condition corresponding to the C-SN for subsequent CPAC.

[1101] Based on the event type and / or corresponding parameters of the execution condition provided by the C-SN, the MN can forward this information to the S-SN, and the S-SN generates the execution condition corresponding to this C-SN for subsequent CPAC based on this.

[1102] As an example, the network side currently configures candidate PSCell1 for the UE for subsequent CPAC, and is preparing to configure candidate PSCell2 and PSCell3 for the UE. Candidate PSCell2 corresponds to T-SN2, and PSCell3 corresponds to T-SN3.

[1103] The MN sends a first message to T-SN2, which includes information about PSCell 1 and PSCell 3, and requests T-SN2 to prepare resources and candidate configurations for PSCell 2. Based on the first message, T-SN2 generates PSCell 2 as a serving cell, supports subsequent CPAC, and the target cells are execution conditions 1 and execution conditions 3 of PSCell 1 and PSCell 3, respectively, and the corresponding measurement configurations. T-SN2 sends the configuration information of execution condition 1, execution condition 3, and PSCell 2 including the measurement configuration to the MN via a confirmation message of the first message.

[1104] It should be noted that the operation of T-SN3 is similar to that of T-SN2.

[1105] The MN integrates the received confirmation messages of the first messages sent by multiple T-SNs to generate configuration information to be sent to the UE.

[1106] Option 2:

[1107] Before the MN sends the subsequent CPAC configuration for the UE, the MN sends a list of all candidate PSCells that have been prepared and confirmed by the Candidate SN to each Candidate SN. After receiving the PSCell list, the Candidate SN generates the execution conditions for the subsequent CPAC corresponding to the CPAC configuration prepared by the Candidate SN.

[1108] As shown in Figures 6c and 6d, Figure 6c is a schematic diagram of a process of initiating CPAC by a MN according to an exemplary embodiment. Figure 6d is a schematic diagram of a process of initiating CPAC by a SN according to an exemplary embodiment.

[1109] Example 1: In response to the network side (MN or S-SN, corresponding to the subsequent CPAC initiated by the MN or SN, respectively) configuring a first mobility operation (subsequent CPAC) for the UE, the MN sends a first message to the T-SN, requesting the T-SN to prepare resources for the CPAC operation subsequent to the first mobility operation of the UE. The T-SN completes the subsequent CPAC preparation and sends a corresponding confirmation message to the MN to confirm the subsequent CPAC configuration. The MN sends a second message to the T-SN.

[1110] Embodiment 2: Based on embodiment 1, the second message includes second information, wherein the second information includes at least one of the following information:

[1111] 2.1, the UE's existing (configured) candidate target cells (PSCells) that can be used for subsequent CPAC;

[1112] 2.2, the accepted (or confirmed) candidate target cell (PSCell) configured for the UE that can be used for subsequent CPAC;

[1113] 2.3. The network side needs this C-SN to generate the candidate target cell (PSCell) corresponding to the execution conditions for subsequent CPAC;

[1114] Exemplarily, in addition to the above-mentioned candidate target cell identifier (for example, the PCI of the target cell, the Global ID of the target cell, etc.), it may also include one or more of the candidate target node identifier corresponding to the candidate target cell, the measurement result of the candidate target cell, and the frequency information corresponding to the candidate target cell.

[1115] Exemplarily, the candidate target cells that can be used for subsequent CPAC are all information of candidate target cells for subsequent CPAC configured (and / or) accepted by the network side for this UE;

[1116] Exemplarily, the candidate target cells that can be used for subsequent CPAC are information of all candidate target cells for subsequent CPAC that are configured by the network side for this UE (and / or) received by other candidate target nodes (except the candidate target node that receives the second message);

[1117] Exemplarily, the candidate target cell that can be used for subsequent CPAC is information of some candidate target cells that are configured by the network side for this UE (and / or) received by the network side based on implementation determination;

[1118] The network side may be MN or S-SN.

[1119] Embodiment 3: Based on any one of Embodiments 1-2, the second message may be an Xn message and / or an inter-node RRC message.

[1120] 3.1, Xn message: SN Modification Request message (SN Modification Request);

[1121] 3.2, Inter-node RRC message: CG-ConfigInfo;

[1122] Example 4-6, same as Example 4-6 of Scheme 1.

[1123] Example 7: Based on any one of Examples 1-6, the T-SN receives a second message sent by the MN, and generates execution conditions for the subsequent CPAC based on the candidate target cells for the subsequent CPAC and the corresponding measurement result information contained in the second message and the candidate target cells configured by the T-SN for this UE.

[1124] The T-SN needs to generate a set of execution conditions for subsequent CPACs for each candidate target cell prepared by the T-SN, where each execution condition in the set corresponds to processing a candidate target cell other than the first candidate target cell. If necessary, the T-SN updates the measurement configuration of the first candidate target cell, where the measurement configuration corresponds to the set of execution conditions.

[1125] Embodiment 8: The T-SN sends a confirmation message of the second message, where the confirmation message includes the generated execution condition for subsequent CPAC and / or the updated measurement configuration.

[1126] Example 9: Same as Example 9 in Scheme 1.

[1127] As an example, the network side currently configures candidate PSCell1 for the UE for subsequent CPAC, and is preparing to configure candidate PSCell2 and PSCell3 for the UE. Candidate PSCell2 corresponds to T-SN2, and PSCell3 corresponds to T-SN3.

[1128] The MN sends a first message to T-SN2, requesting T-SN2 to prepare resources and candidate configurations for PSCell 2. T-SN2 sends a confirmation message of the first message, which includes the candidate configurations of PSCell 2.

[1129] When MN receives the confirmation messages of T-SN2 and T-SN3, and before sending the configuration information to the UE, MN sends a second message to T-SN2. Based on the second information, T-SN2 generates PSCell 2 as the serving cell, supports subsequent CPAC, and the target cells are execution conditions 1 and execution conditions 3 of PSCell1 and PSCell3 respectively, as well as the corresponding measurement configuration. T-SN2 sends execution condition 1, execution condition 3 and the updated measurement configuration information to MN through a confirmation message of the second message.

[1130] It should be noted that the operation of T-SN3 is similar to that of T-SN2.

[1131] The MN integrates the received confirmation messages of the second messages sent by multiple T-SNs and generates configuration information to be sent to the UE.

[1132] Option 3: Integrate Option 1 and Option 2.

[1133] Option 1: In the first message, the MN sends the candidate target cells that the UE has configured to the T-SN. Then, before the MN configures the subsequent CPAC configuration for the UE, the MN sends a second message to the T-SN. The second message contains other candidate target cells that the T-SN has accepted (or confirmed).

[1134] Option 2: Or in response to executing embodiments 1-2 in solution 1, all candidate SNs do not accept all candidate cells recommended by the MN or the S-SN, and before the MN configures subsequent CPAC configuration for the UE, the MN sends a second message to the T-SN, where the second message includes candidate target cells accepted (or confirmed) by other T-SNs.
