Description

Cell processing method and device, master node, source auxiliary node and target auxiliary node

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a cell processing method, a device, a master node, a source auxiliary node, and a target auxiliary node.

Background

The primary serving cell (Primary Secondary cell, PSCell) condition change (conditional PSCell change, CPC) of the Secondary cell group triggered by the primary Node (MN) is set by the MN to an alternative cell and corresponding execution conditions, while in the CPC scenario triggered by the Secondary Node (SN), the setting of the alternative cell and execution conditions is done by the source SN (or S-SN). If MN-triggered CPC and SN-triggered CPC coexist, there may be a candidate cell (candidate cell) selected by MN-triggered CPC that is the same as the candidate cell (or candidate cell) of SN-triggered CPC, which may cause the network side to configure multiple sets of CPC configurations for the same candidate cell, increase network and air interface burdens, and may cause the User Equipment (UE) to perform redundant measurement, and increase power consumption overhead.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Conditional handover (conditional handover, CHO) and PSCell condition change (intra-SN conditional PSCell change, intra-SN CPC) within SNs without MN participation are currently introduced in communication systems to improve robustness at handover or PSCell change.

In addition, PSCell condition changes within MN triggered SNs (intra-SN conditional PSCell change, MN triggered intra-SN CPC), PSCell condition changes within MN-involved SNs (intra-SN conditional PSCell change, MN-involved intra-SN CPC), PSCell condition changes between MN-triggered SNs (inter-SN conditional PSCell change, MN-triggered inter-SN CPC), PSCell condition changes between SN-triggered SNs (inter-SN conditional PSCell change, SN-triggered inter-SN CPC) and conditional PSCell additions (conditional PSCell addition, CPA) are further introduced.

For CPC initiated by MN, MN sends the selected candidate cells to target SN (or called T-SN) through message between nodes, T-SN selects corresponding CPC candidate cell from candidate cells recommended by MN, and generates corresponding reconfiguration message to feed back to MN. The MN sets corresponding execution conditions for CPC candidate cells, then the MN completes matching of the execution conditions of the CPC candidate cells and the corresponding reconfiguration messages thereof, and the matching is sent to the UE through infinite resource control (Radio Resource Control, RRC) reconfiguration messages.

Setting corresponding execution conditions for the candidate cells aiming at the Inter-SN CPC and S-SN initiated by the SN, sending the selected candidate cells and the execution conditions to the MN through Inter-node messages, then providing the candidate cells for the T-SN by the MN, selecting CPC candidate cells by the T-SN, generating reconfiguration messages for the CPC candidate cells, and delivering the reconfiguration messages to the MN. And finally, the MN completes the matching of the execution condition of the CPC candidate cell and the corresponding reconfiguration message thereof, and the matching is sent to the UE through the RRC reconfiguration message.

Setting candidate CPC cells aiming at intra-SN CPC initiated by SN, S-SN, generating corresponding reconfiguration information and execution conditions, matching the execution conditions with the reconfiguration information of the corresponding CPC cells, and carrying out transmission in RRC reconfiguration information of SN side through MN side to send to UE or directly sending to UE through SN side when signaling radio bearer 3 (Signalling Radio Bearer, SRB 3) is configured.

After the UE receives the reconfiguration of the condition, the UE does not immediately perform handover or PSCell change or PSCell addition like the conventional handover or PSCell change or PSCell addition, but saves the received configuration, and performs measurement and evaluation on the configured candidate cell until there is a cell meeting the execution condition of CHO/CPA/CPC configuration, and then the UE performs a corresponding reconfiguration message of the stored cell, so as to perform a corresponding handover or PSCell addition process, that is, complete downlink synchronization and trigger a random access process to access a target Primary serving cell (PCell) or PSCell.

In the MN-triggered CPC and SN-triggered CPC coexistence scenario, the candidate cell (candidate cell) where the MN-triggered CPC selection exists is the same as the candidate cell (or candidate cell) of the SN-triggered CPC, which may cause the network side to configure multiple sets of CPC configurations for the same candidate cell, increase network and air interface burdens, and may cause the User Equipment (UE) to perform redundant measurement, and increase power consumption overhead.

The terminal device according to the embodiments of the present application may be a device that provides voice and/or data connectivity to a user, a handheld device with a wireless connection function, or other processing device connected to a wireless modem, etc. The names of the terminal devices may also be different in different systems, for example in a 5G system, the terminal devices may be referred to as User Equipment (UE). The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network.

The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (access terminal), user terminal device (user terminal), user agent (user agent), user equipment (user device), and the embodiments of the present application are not limited.

The embodiment of the application provides a cell processing method, a device, a main node, a source auxiliary node and a target auxiliary node, so as to solve the problems that when CPC triggered by an MN and CPC triggered by an SN coexist, a plurality of sets of CPC configurations aiming at the same candidate cell may exist in network side configuration, thereby increasing network burden and increasing UE function overhead.

As shown in fig. 1, an embodiment of the present invention provides a cell processing method, which is applied to a master node MN, and specifically may include the following steps:

step 11: a first set of cells transmitted by a source SN is received.

The first cell set contains cell information of alternative cells, wherein the alternative cells are cells configured by primary service cell condition change CPC of secondary cell groups between SNs triggered by source SNs.

Optionally, when the source SN determines that CPC configuration between SNs is to be triggered, an SN change request message (SN Change Required information) may be sent to the MN, where the SN change request message carries cell information of its recommended cell (where the cell may be referred to as an alternative cell), for example, the cell information may include the recommended alternative cell and/or an execution condition corresponding to the CPC configuration triggered by the cell information, which is not limited to this embodiment of the present invention.

Optionally, before the MN does not receive the first set of cells sent by the source SN, the method further includes:

And sending a first message to the source SN, wherein the first message carries third indication information related to each cell contained in a second cell set, and the second cell set contains second candidate cells of CPC configuration between SNs triggered by the MN.

For the description of the third indication information, please refer to the contents described in the following embodiments, and detailed description thereof will not be provided here.

Thus, assuming that the source SN receives the first message sent by the MN before the CPC configuration between SNs is performed, here the candidate cells included in the first set of cells sent to the MN in step 101 will not overlap with the second candidate cell included in the second set of cells.

Assuming that the source SN does not receive the first message sent by the MN before performing CPC configuration between SNs, but receives the first message sent by the MN before sending the first set of cells to the MN, the source SN may update the candidate cells included in the first set of cells based on the first message to ensure that the updated candidate cells included in the first set of cells do not overlap with the second candidate cells included in the second set of cells.

Assuming that the source SN does not receive the first message sent by the MN before the CPC configuration between SNs is performed, and does not receive the first message sent by the MN before the first cell set is sent to the MN, the source SN sends the first cell set to the MN, where the first cell set is the first cell set described in step 11.

Step 12: and determining whether the cell information of the candidate cells contained in the first cell set is overlapped with the cell information of the candidate cells contained in the second cell set.

And the second cell set comprises second candidate cells of CPC configuration between the SNs triggered by the MN.

Alternatively, the second candidate cell of the CPC configuration between the MN-triggered SNs included in the second cell set may refer to a cell of the determined MN-triggered CPC configuration when the MN-triggered CPC configuration has completed interaction with a corresponding target SN.

For example: when the MN triggers CPC configuration, the MN may send its selected cell (which may be referred to as an alternative cell) to the target SN (or referred to as a T-SN) through an inter-node message, where the target SN selects a cell of the corresponding CPC configuration (which may be referred to as a candidate cell) from the candidate cells recommended by the MN, and generates a corresponding reconfiguration message to be fed back to the MN, that is, after the MN triggers CPC configuration and has completed interaction with the corresponding target SN, determines a second candidate cell.

Optionally, determining whether to overlap with a cell included in the second cell set according to cell information of an alternative cell included in the first cell set may include: determining whether the candidate cells contained in the first cell set overlap with the second candidate cells contained in the second cell set; alternatively, it may further include: whether or not a first candidate cell included in a first candidate cell set of source SN triggered inter-SN CPC configuration determined based on the first cell set overlaps with a second candidate cell included in the second cell set is further described in connection with an embodiment.

In addition, it should be further noted that, if step 11 is triggered before the interaction between the MN and the corresponding target SN is completed (i.e., before the second candidate cell configured by the CPC of the MN is not determined), and the MN determines the candidate cell configured by the CPC, then the cells included in the second cell set may be understood as the candidate cells configured by the MN.

Further, determining whether to overlap with a cell included in a second cell set according to cell information of an alternative cell included in the first cell set may include: determining whether the candidate cells contained in the first cell set overlap with the candidate cells contained in the second cell set; alternatively, it may further include: the method for specifically determining whether the first candidate cell included in the first candidate cell set and the candidate cell included in the second cell set overlap based on the source SN triggered inter-SN CPC configuration determined by the first cell set, and the corresponding processing based on the determination result obtained after the determination are similar to the case where the second candidate cell includes the second candidate cell in the second cell set and the source SN triggered inter-SN CPC configuration described above, and in order to avoid repetition, the following embodiment will be described with respect to the case where the second candidate cell is included in the second cell set.

Step 13: and processing each cell in the first cell set and the second cell set according to the determination result.

Optionally, the determining result is: and determining whether the result is overlapped with the cells contained in the second cell set according to the cell information of the candidate cells contained in the first cell set, or determining whether the result is overlapped with the cells contained in the second cell set according to the first candidate cells contained in the first candidate cell set of the source SN triggered inter-SN CPC configuration determined by the first cell set.

If the result of the determination in step 12 is that there is an overlap, the MN determines cells belonging to the overlapping of the first cell set and the second cell set as overlapping cells and determines execution conditions for the overlapping cells. I.e. whether a certain overlapping cell uses the CPC execution conditions configured by the MN or the CPC execution conditions configured by the source SN, is determined by the MN.

In this embodiment, by receiving the first cell set including the cell information of the candidate cells sent by the source SN, determining whether the second candidate cells configured with the CPC configured with the SNs triggered by the MNs and included in the second cell set overlap according to the cell information of the candidate cells included in the first cell set, and processing each cell in the first cell set and the second cell set according to the determination result, when the CPC configured with the SNs triggered by the MNs and the CPC configured with the SNs triggered by the source SN coexist, it can be ensured that the CPC candidate cells configured with the SNs triggered by the MNs and the CPC candidate cells configured with the SNs triggered by the source SN are different from each other, so as to avoid configuring multiple sets of CPC configurations for the same candidate cell on the network side, to reduce network and air interface burden, and also avoid the UE side from executing redundant measurement, and reduce power consumption overhead.

Since in the embodiments described in the present application, there are a CPC configuration between MN trigger SNs and a CPC configuration between source SN trigger SNs, and the CPC configuration between source SN trigger SNs needs to be forwarded to the target SN by the MN, the specific implementation procedure includes, but is not limited to, the following cases:

first case: firstly, triggering CPC configuration among SNs by the MN to obtain a second cell set, wherein the second cell set comprises cell information of CPC cells configured among the SNs triggered by the MN; and secondly, receiving a first cell set of CPC configuration between source SNs, wherein the first cell set contains cell information of CPC alternative cells of the source SN-triggered inter-SN configuration.

Then for the first case herein, in step 12, it is determined whether the candidate cells contained in the first set of cells overlap with the cells contained in the second set of cells;

if there is an overlap, in step 13, the MN may delete the cells belonging to the overlap (hereinafter referred to as "overlapping cells"), where deletion may refer to deletion of the cell identifier of the overlapping cell, or deletion of the target SN information corresponding to the overlapping cell. If the information of the alternative cells contained in the first cell set is deleted, the MN sends a second SN adding request message to a target SN corresponding to the remaining alternative cells in the first cell set, wherein the second SN adding request message contains the cell information of the remaining alternative cells in the first cell set. And then, the MN receives the first candidate cells which are sent by each target SN and are selected for the rest candidate cells, and sends the first candidate cells and the second candidate cells to the UE.

Optionally, if there is an overlap, in step 13, the MN sends a first SN addition request message to a target SN corresponding to an alternative cell included in the first cell set, where the first SN addition request message includes cell information of each alternative cell in the first cell set. And then, the MN receives the first candidate cell information fed back by each target SN, at this time, the MN executes whether the first candidate cell is overlapped with a second candidate cell contained in the second cell set or not again based on the received first candidate cell, if so, the MN determines the overlapped candidate cell, determines an execution condition for the overlapped candidate cell, and then sends the cell information of the redetermined execution condition to the UE.

It should be noted that, here, the deletion of the MN for the overlapping cells may be deleting the overlapping cells from the first cell set, so as to ensure that when the target SN selects the first candidate cell, the target SN may not select the cell where the overlapping occurs, that is, determine that the execution condition corresponding to the overlapping cell uses MN configuration; the overlapping cells may be deleted from the second cell set, that is, the execution condition corresponding to the overlapping cells may be determined and configured by the source MN.

If the first candidate cells are not overlapped, the MN sends a first SN adding request message to a target SN corresponding to the candidate cells contained in the first cell set, the target SN selects the first candidate cells from the first cell set and feeds the first candidate cells back to the MN, and the MN sends the first candidate cells and the second candidate cells to the UE.

Second case: and before the second cell set is obtained by the CPC configuration between the source SNs, receiving a first cell set of the CPC configuration between the source SNs, wherein the first cell set contains the cell information of CPC alternative cells of the CPC configuration between the source SNs triggered by the source SNs.

For the second case here, the same steps as step 12 and step 13 can be performed for the first case; before executing step 12, the MN may send a first SN addition request message to a target SN corresponding to an alternative cell included in the first cell set, where the first SN addition request message includes cell information of each of the alternative cells in the first cell set. Then, the MN receives the first candidate cell information fed back by each target SN. Then for this case, the MN will perform, in step 12, whether the first candidate cell overlaps with a second candidate cell contained in the second cell set, based on the received first candidate cell; if there is overlap, in step 13, the MN directly determines the execution condition for the overlapped cell, and then sends the cell information for redetermining the execution condition to the UE. If there is no overlap, the MN transmits the first candidate cell and the second candidate cell to the UE.

For example: when the source SN determines that CPC configuration between SNs is to be triggered, a SN Change Required message may be sent to the MN, where the cell information carries cell information of the recommended candidate cell, e.g., the cell information may include the recommended candidate cell and/or an execution condition corresponding to the CPC configuration; the MN receives the SN Change Required message sent by the source SN, and may determine, according to the cell information of the candidate cell recommended by the source SN, whether the recommended candidate cell overlaps with the second candidate cell included in the second cell set.

Optionally, the determining whether to overlap with the cells contained in the second cell set according to the cell information of the candidate cells contained in the first cell set includes:

determining a first candidate cell set of inter-SN CPC configuration triggered by a source SN based on the first cell set;

and judging whether the cell information of the first candidate cell contained in the first candidate cell set is overlapped with the cell contained in the second cell set or not.

Specifically, determining, based on the first cell set, a first candidate cell set configured by source SN triggered inter-SN CPC, including: a first SN adding request message is sent to a target SN corresponding to an alternative cell contained in the first cell set, wherein the first SN adding request message contains cell information of each alternative cell in the first cell set;

and receiving a first candidate cell sent by the target SN, wherein the first candidate cell is determined by the target SN according to the candidate cell carried in the first SN addition request message.

receiving a first candidate cell sent by the target SN, wherein the first candidate cell is determined by the target SN according to the candidate cell carried in the first SN addition request message;

Determining whether the first candidate cell overlaps with a second candidate cell contained in the second set of cells.

For example: when the source SN determines that CPC configuration between SNs is to be triggered, a SN Change Required message may be sent to the MN, where the cell information of the recommended candidate cell is carried, e.g., the cell information may include the recommended candidate cell and/or an execution condition corresponding to the triggering CPC configuration. The MN receives the SN Change Required message sent by the source SN, and may send a first SN addition request message to the target SN corresponding to the candidate cell recommended by the source SN, where the first SN addition request message may include cell information of all the candidate cells. The target SN may select a corresponding candidate cell (i.e., the first candidate cell) from the candidate cells and send the candidate cell to the MN.

In this way, the MN receives the first candidate cell sent by the target SN, where the first candidate cell is determined by the target SN according to the candidate cell carried in the first SN addition request message, and may determine, according to the first candidate cell, whether it overlaps with the second candidate cell included in the second cell set.

A. deleting a first candidate cell overlapped with a second candidate cell contained in the second cell set from the first cell set, and respectively sending a second SN adding request message to target SNs corresponding to the remaining candidate cells in the first cell set, wherein the second SN adding request message contains the cell information of the remaining candidate cells. This embodiment, that is, the MN deletes, from the first cell set, a first candidate cell overlapping with a second candidate cell included in the second cell set, and does not carry cell information of the first candidate cell when sending a second SN addition request message to a target SN where the first candidate cell is located.

B. Deleting the identification of the target SN corresponding to the first candidate cell overlapped with the second candidate cell contained in the second cell set from the first cell set, and respectively sending second SN adding request messages to the residual target SNs corresponding to the first cell set, wherein the second SN adding request messages contain cell information of the candidate cells corresponding to the residual target SNs. In this embodiment, the MN deletes, from the first set of cells, the identification of the target SN corresponding to the first candidate cell overlapping with the second candidate cell included in the second set of cells, and the MN does not send an SN addition request message to the target SN corresponding to the first candidate cell.

It should be noted that, since the correspondence between the candidate cells and the target SN may be a many-to-one relationship, it means that after the overlapping first candidate cells are determined, the target SN corresponding to the overlapping first candidate cells may correspond to more than one first candidate cell, and if the target SN is deleted, it means that multiple candidate cells corresponding to the target SN are excluded. For example: the candidate cells corresponding to the target SN1 comprise C1, C2 and C3; if once C2 is determined to belong to the overlapping cell, when deleting the target SN1, it means that synchronization also deletes C1 and C3.

C. And sending a first SN adding request message to a target SN corresponding to the alternative cells contained in the first cell set, wherein the first SN adding request message contains the cell information of each alternative cell in the first cell set.

Example 1: when the second candidate cell of the at least one MN-triggered CPC configuration and the candidate cell of the source SN-triggered CPC configuration have the same cell (i.e., it is determined that the candidate cell included in the first cell set overlaps with the second candidate cell included in the second cell set), the MN may directly decide to adopt the MN-triggered CPC configuration and/or the source SN-triggered CPC configuration.

The triggered CPC configuration herein may be understood as the CPC execution condition of the configuration described above.

Specifically, when the MN triggers the CPC configuration and interaction with the corresponding target SN is completed, determining a second candidate cell of the MN triggering the CPC configuration.

For example, the second candidate cell of the MN triggered CPC configuration comprises: cell 1, cell 2, cell 3, where cells 1, 2 correspond to target SN 1 and cell 3 corresponds to target SN 2.

When the source SN determines that CPC configuration between SNs is to be triggered, a SN Change Required message is sent to the MN, where the MN carries cell information of its recommended candidate cell and/or an execution condition corresponding to the triggering CPC configuration.

For example, alternative cells where the source SN triggers CPC configuration recommendation between SNs include: cell 1, cell 2, cell 5, where cells 1, 2, 5 correspond to target SN 1. The source SN may carry the cell information of cells 1, 2, 5 and/or its execution conditions corresponding to the trigger CPC configuration to the MN in a SN Change Required message.

After receiving SN Change Required message sent by source SN, MN obtains recommended alternative cell of source SN and corresponding alternative target SN of alternative cell. The MN discovers that the same cell and/or the same target SN node exist in the second candidate cell with CPC configuration among the source SN and the source SN (namely, the source SN recommends the second candidate cell with the source SN to overlap with the second candidate cell with the MN configuration or the source SN recommends the candidate cell to overlap with the target SN corresponding to the second candidate cell with the MN configuration).

As based on the above example, the MN finds cells 1, 2 in which the target SN 1 is configured in both the second candidate cell and the candidate cell recommended by the source SN. At this point, the MN may directly decide to take the MN-triggered CPC configuration and/or the source SN-triggered CPC configuration, and if the MN determines to take the MN-triggered CPC configuration as an example, the MN may perform one or more of the following:

mode one: the MN excludes the cells which are the same as the CPC candidate cells of the CPC configuration triggered by the MN from the candidate cells provided by the source SN (namely, deletes a first candidate cell overlapped with a second candidate cell contained in the second cell set from the first cell set), and sends a second SN adding request message to target SN nodes where the rest candidate cells except the first candidate cell in the first cell set are located; the second SN addition request information carries cell information of the remaining candidate cells, but does not carry cell information of the first candidate cell, so that when CPCs configured between SNs triggered by MNs coexist with CPCs configured between SNs triggered by source SNs, CPC candidate cells configured between SNs triggered by MNs and CPC candidate cells configured between SNs triggered by source SNs can be guaranteed to be different, and/or a network side is prevented from configuring multiple sets of CPC configurations for the same candidate cell, so that network and air interface burdens are reduced, and the UE side can be prevented from executing redundant measurement, and power consumption overhead is reduced.

Alternatively, the MN may exclude the same part of cells from the candidate cells provided by the source SN as the CPC candidate cells of the CPC configuration triggered by the MN. For example, if the MN determines that the MN triggered CPC configuration is adopted for the cell 1, the MN excludes the cell 1 from the candidate cells provided by the source SN, that is, the MN sends the target SN 1 the cell information of the candidate cells 2 and 5 recommended by the source SN, but does not carry the cell information of the cell 1, so that the MN can exclude the same part of the cells as the CPC candidate cells configured by the MN from the candidate cells provided by the source SN, and can avoid that the target SN may repeatedly configure for the overlapped cell 1, so as to reduce network and air interface burden, and avoid that the UE side performs redundant measurement and reduces power consumption overhead.

Alternatively, the MN may exclude all cells from the candidate cells provided by the source SN that are the same as the CPC candidate cell for the MN triggered CPC configuration. For example, if the MN determines that the MN triggered CPC configuration is adopted for the cells 1 and 2, the MN excludes the cells 1 and 2 from the candidate cells provided by the source SN, that is, the MN sends the target SN 1 the cell information of the candidate cell 5 recommended by the source SN, which is carried in the second SN addition request message, but does not carry the cell information of the cells 1 and 2, so that the CPC candidate cells configured between the MN triggered SNs and the CPC candidate cells configured between the source SN are ensured to be different, and further, the situation that the target SN may be repeatedly configured for the overlapped cells 1 and 2 can be effectively avoided, so as to reduce network and air interface burden, avoid the UE side from performing redundant measurement, and reduce power consumption overhead thereof.

Mode two: the MN excludes the target SN node where the same cell as the second candidate cell is located from the candidate cells provided by the source SN (i.e., deletes the identifier of the target SN corresponding to the first candidate cell overlapped with the second candidate cell included in the second cell set from the first cell set), and sends the second SN addition request message to the target SNs corresponding to the remaining candidate cells (i.e., the remaining target SNs) in the first cell set except for the first candidate cell, respectively, while the MN does not send the SN addition request message to the target SN where the first candidate cell is located, so that when the CPC configured between the MN-triggered SN and the source SN-triggered CPC coexist, it can be ensured that the CPC candidate cell configured between the MN-triggered SN and the source SN-triggered SN candidate cell are different from each other, and/or avoid configuring multiple sets of CPC for the same candidate cell on the network side, so as to reduce the load of the network and the air interface, and also can reduce the redundant measurement overhead performed on the UE side.

Based on the above example, the MN excludes the target SN 1 from the candidate cells provided by the source SN, i.e., the MN does not send the target SN 1 an SN addition request message for configuring the source SN triggered CPC configuration.

In this embodiment, when it is determined that there is an overlap with the second candidate cell included in the second cell set, the MN may perform deletion of the first candidate cell overlapping with the second candidate cell included in the second cell set from the first cell set and send the second SN addition request message to the target SNs corresponding to the remaining candidate cells in the first cell set, or perform deletion of the target SN identification corresponding to the first candidate cell overlapping with the second candidate cell included in the second cell set from the first cell set and send the second SN addition request message to the remaining target SNs corresponding to the first cell set, respectively, so that when CPC configured between the SN triggered by the MN and CPC configured between the SN triggered by the source SN coexist, the CPC candidate cell configured between the SN triggered by the MN and the source SN may be different from each other, and/or avoid that multiple configurations on the network side are configured for the same cell, so that the power consumption of the CPC and the UE may be reduced, and the redundancy burden may be further reduced.

Example 2: and determining a second candidate cell of the MN triggering CPC configuration when the MN triggers CPC configuration and interaction between the MN and the corresponding target SN is completed.

After receiving the SN Change Required message sent by the source SN, the MN obtains an alternative cell recommended by the source SN (i.e., a cell in the first cell set) and an alternative target SN corresponding to the alternative cell. The MN sends a first SN adding request message to a target SN corresponding to an alternative cell contained in the first cell set, wherein the first SN adding request message contains cell information of each alternative cell in the first cell set.

For example, the MN sends a first SN addition request message to the target SN 1, where the first SN addition request message carries cell information of the candidate cells 1, 2, 5 recommended by the source SN and/or execution conditions of CPC configuration triggered by the source SN corresponding to each of the candidate cells.

The target SN receives a first SN addition request message sent by the MN, selects a first candidate cell of which the source SN triggers CPC configuration from the candidate cells according to the cell information of the candidate cells contained in the first SN addition request message, and sends the first candidate cell to the MN.

Optionally, if the target SN determines that a CPC implementation condition has been configured for the first candidate cell, the first candidate cell is used as a first candidate cell, and is sent to the MN. That is, the target SN determines a first candidate cell overlapping with a second candidate cell included in the second cell set in the candidate cells, and configures CPC execution conditions for the first candidate cell, so that the target SN may still select the first candidate cell as the first candidate cell, but no new configuration information is generated for the first candidate cell, thereby avoiding repeated CPC configuration for the same candidate cell, and reducing network and air interface burden.

For example, the target SN 1 may still select cell 1 and/or cell 2 as the first candidate cell, but no new configuration information is generated for cells 1, 2 anymore.

Optionally, if the target SN determines that the CPC execution condition has been configured for the first candidate cell, the target SN does not select the first candidate cell as the first candidate cell, thereby avoiding configuring multiple sets of CPC configurations for the same candidate cell on the network side, so as to reduce network and air interface burden.

For example, the target SN 1 only selects the cell 5 as the first candidate cell, and does not select the cells 1 and 2 as the first candidate cell.

The MN receives a first candidate cell set sent by the target SN, wherein the first candidate cell set comprises a first candidate cell determined by the target SN according to the candidate cell carried in the first SN addition request message; the MN determines, according to the first candidate cell set, whether the first candidate cell in the first candidate cell set overlaps with the second candidate cell contained in the second cell set, and processes each cell in the first cell set and the second cell set according to the determination result (that is, according to the first candidate cell contained in the first candidate cell set configured by the source SN and the result of determining whether the first candidate cell overlaps with the cell contained in the second cell set), so that when the CPC configured between the SNs triggered by the MN and the CPC configured between the SNs triggered by the source SN coexist, it can be ensured that the CPC candidate cell configured between the SNs triggered by the MN and the CPC candidate cell configured between the SNs triggered by the source SN are different from each other, and/or the CPC configuration of multiple sets for the same candidate cell is avoided to be configured by the network side, so as to reduce the load of the network and the air interface, and also avoid the UE side from executing redundant measurement, and reduce the power consumption overhead.

Optionally, according to the determination result, processing each cell in the first cell set and the second cell set includes: if the target SN is determined to overlap with the second candidate cells contained in the second cell set, respectively sending first indication information to the target SNs corresponding to the first candidate cells overlapped with the second candidate cells contained in the second cell set, wherein the first indication information is used for indicating the target SNs to perform CPC configuration selection for the first candidate cells, and the CPC configuration selection comprises CPC execution conditions configured by the MN or CPC execution conditions configured by the source SNs;

PCI of the first alternative cell;

cell frequency point information of the first alternative cell;

identification of a target SN corresponding to the first candidate cell;

CPC execution conditions configured by MN;

CPC execution conditions configured by source SN.

Specifically, when the MN determines that there is an overlap with the second candidate cell included in the second cell set, the MN may instruct the target SN corresponding to the first candidate cell overlapping with the second candidate cell included in the second cell set to select to adopt the source SN triggered CPC configuration and/or the MN triggered CPC configuration. At this time, the target SN receives first indication information sent by the MN, determines that a source SN triggered CPC configuration and/or an MN triggered CPC configuration are adopted for the first candidate cell, and sends a response message for the first indication information to the MN, where the response message includes one or more of the following information:

PCI of the first alternative cell;

cell frequency point information of the first alternative cell;

identification of a target SN corresponding to the first candidate cell;

indication identification of CPC execution conditions configured using the MN;

Correspondingly, the cell processing method at the MN side further comprises the following steps:

PCI of the first alternative cell;

cell frequency point information of the first alternative cell;

identification of a target SN corresponding to the first candidate cell;

indication identification of CPC execution conditions configured using the MN;

In this embodiment, when the MN determines that there is an overlap with the second candidate cell included in the second cell set, the MN may instruct the target SN corresponding to the first candidate cell overlapping with the second candidate cell included in the second cell set to select to adopt the source SN-triggered CPC configuration and/or the MN-triggered CPC configuration. At this time, the target SN receives the first indication information sent by the MN, determines that the source SN triggered CPC configuration and/or the MN triggered CPC configuration are adopted for the first candidate cell, and sends a response message for the first indication information to the MN, so that when the CPC configured between the MN triggered SNs and the CPC configured between the source SN triggered SNs coexist, it can be ensured that the CPC candidate cells configured between the MN triggered SNs and the CPC candidate cells configured between the source SN triggered SNs are different from each other, thereby avoiding that the network side configures multiple sets of CPC configurations for the same candidate cell, reducing network and air interface burden, and also avoiding that the UE side performs redundant measurement and reduces power consumption overhead.

Example 3: when the second candidate cell of the at least one MN-triggered CPC configuration and the candidate cell of the source SN-triggered CPC configuration have the same cell, the MN may request the target SN to choose to take the source SN-triggered CPC configuration and/or the MN-triggered CPC configuration.

After receiving SN Change Required message sent by source SN, MN obtains recommended alternative cell of source SN and corresponding alternative target SN of alternative cell. The MN discovers that a first alternative cell which is the same as a second alternative cell of CPC configuration among the MSNs triggered by the source SN exists in the alternative cells provided by the source SN, and/or the target SN where the first alternative cell exists, the MN sends first indication information to the target SN where the first alternative cell exists, wherein the first indication information is used for indicating the target SN to perform CPC configuration selection for the first alternative cell, namely indicating the target SN to select CPC configuration triggered by the MN and/or CPC configuration triggered by the SN. Wherein the first indication information includes: one or more of PCI of the first candidate cell, cell frequency point information of the first candidate cell, identification of a target SN corresponding to the first candidate cell, CPC execution conditions configured by MN and CPC execution conditions configured by source SN.

Based on the above example, if the MN finds that the second candidate cell and the candidate cell recommended by the source SN are both configured with the cell 1, 2 of the target SN 1, the MN sends first indication information to the target SN 1, where the first indication information carries the PCIs of the cell 1, 2 and/or the frequency point information of the cell 1, 2, the execution condition of the cell 1, 2 in the CPC configuration triggered by the MN, the execution condition of the cell 1, 2 in the CPC configuration triggered by the source SN, and so on.

The target SN determines that a source SN-triggered CPC configuration and/or a MN-triggered CPC configuration is to be adopted for the first candidate cell (e.g., a source SN-triggered CPC configuration is adopted for the first candidate cell, or a MN-triggered CPC configuration is adopted for the first candidate cell, or a source SN-triggered CPC configuration is adopted for some cells in the first candidate cell, a MN-triggered CPC configuration is adopted for another cell, etc.), and feeds back a response message for the first indication information to the MN. Wherein, the response message includes: one or more of PCI of the first candidate cell, cell frequency point information of the first candidate cell, identification of a target SN corresponding to the first candidate cell, indication identification of CPC execution conditions configured by using MN, and indication identification of CPC execution conditions configured by using source SN.

For example, if the target SN 1 determines that the source SN is selected for cell 1 to configure the CPC and the MN is selected for cell 2, the target SN 1 carries in the response message the indication information of the CPC configuration triggered by the source SN for cell 1 and the indication information of the CPC configuration triggered by the MN for cell 2. The indication information of CPC configuration triggered by using a source SN for the cell 1 includes: PCI and/or frequency point information of the cell 1, and indication identification of CPC execution conditions configured by using a source SN for the cell 1; the indication information of the CPC configuration triggered by the MN for the cell 2 includes: cell 2's PCI and/or frequency point information, indication identification of CPC execution conditions configured for cell 2 using MN.

Optionally, the foregoing embodiment 3 may be further combined with the foregoing embodiment 1 to implement the cell processing method of the present invention, so that when the CPC configured between the SNs triggered by the MN and the CPC configured between the SNs triggered by the source SN coexist, it may be ensured that the CPC candidate cells configured between the SNs triggered by the MN and the CPC candidate cells configured between the SNs triggered by the source SN are different from each other, thereby avoiding that the network side configures multiple sets of CPC configurations for the same candidate cell, so as to reduce network and air interface burden, and also may avoid that the UE side performs redundant measurement, and reduce power consumption overhead thereof.

Optionally, the method further comprises: transmitting second indication information to the source SN, wherein the second indication information comprises one or more of the following information:

cell frequency point information of the target cell;

identification of a target SN corresponding to the target cell;

indication identification of CPC execution conditions configured using the MN;

Optionally, the second indication information may be used to indicate that the source SN adopts MN-triggered CPC configuration and/or adopts source SN-triggered CPC configuration for the target cell. At this time, after the source SN receives the second indication information, the CPC configuration triggered by the MN and/or the CPC configuration triggered by the source SN may be determined for the target cell; and/or after the source SN receives the second indication information, updating the CPC executing condition corresponding to the target cell according to the second indication information, so as to avoid the network side from configuring multiple sets of CPC configuration aiming at the same candidate cell when CPC configured between the SNs triggered by the MN and CPC configured between the SNs triggered by the source SN coexist, thereby reducing network and air interface burden.

Optionally, the source SN may also send a response message to the MN for the second indication information. Correspondingly, the cell processing method at the MN side further comprises the following steps: receiving a response message aiming at second indication information and sent by the source SN, wherein the response message comprises one or more of the following information:

PCI of the target cell;

cell frequency point information of the target cell;

identification of a target SN corresponding to the target cell;

the updated CPC executing condition corresponding to the target cell;

updated measurement configuration corresponding to the target cell;

It should be noted that, in the embodiment of the present invention, the target cell may be a cell overlapping with the second candidate cell included in the second cell set in the first candidate cell set, or a cell overlapping with the second candidate cell included in the second cell set in the candidate cell included in the first cell set, that is, the embodiment may be combined with at least one embodiment described above. Since both embodiments are similar, in order to avoid repetition, the following description will be made with reference to specific embodiments, based on the target cell being a cell overlapping with a second candidate cell included in the second cell set, among the first candidate cells included in the first candidate cell set.

Example 4: and determining a second candidate cell of the MN triggering CPC configuration when the MN triggers CPC configuration and interaction between the MN and the corresponding target SN is completed.

The MN receives the SN Change Required message sent by the source SN, and may send a first SN addition request message to the target SN corresponding to the candidate cell recommended by the source SN, where the first SN addition request message may include cell information of all the candidate cells. The target SN may select a corresponding candidate cell (i.e., the first candidate cell) from the candidate cells and send the candidate cell to the MN. In this way, the MN receives the first candidate cell sent by the target SN, where the first candidate cell is determined by the target SN according to the candidate cell carried in the first SN addition request message, and may determine, according to the first candidate cell, whether it overlaps with the second candidate cell included in the second cell set.

When the MN determines that the first candidate cell overlaps with a second candidate cell contained in the second cell set, the MN sends second indication information to the source SN so as to indicate the source SN to adopt CPC configuration triggered by the MN aiming at the target cell.

Based on the above example, the MN sends a second indication to the source SN, carrying an indication that an MN triggered CPC configuration is to be adopted for cell 2. The indication information of the CPC configuration triggered by the MN to be adopted for the cell 2 comprises the following steps: cell 2's PCI and/or frequency point information, indication identification of CPC execution conditions configured for cell 2 using MN. Optionally, the indication information of CPC configuration triggered by source SN for cells 1, 5 may also be carried. The indication information of the CPC configuration triggered by the source SN to be adopted for the cells 1 and 5 includes: PCI and/or frequency point information of cells 1, 5, indication identification of CPC execution conditions configured using source SN for cells 1, 5. Of course, as a further alternative embodiment, the MN sends second indication information to the source SN carrying indication information that the MN triggered CPC configuration is to be adopted for cells 1, 2. Optionally, the indication information and the like of the CPC configuration triggered by the source SN may also be carried for the cell 5, which is not limited in this embodiment of the present application.

Or when the MN determines that the first candidate cell overlaps with a second candidate cell contained in the second cell set, the MN sends second indication information to the source SN so as to indicate the source SN to adopt CPC configuration triggered by the MN for the target SN corresponding to the target cell.

For example, the MN sends the second indication information to the source SN, where the second indication information includes: the SN identifier corresponding to the target SN 1 uses, for the target SN 1, an indication identifier of the CPC execution condition configured by the MN.

The source SN feeds back a response message to the MN aiming at the received second indication information, wherein the response message comprises the following components: the PCI of the target cell, the cell frequency point information of the target cell, the identification of the target SN corresponding to the target cell, the updated CPC execution condition corresponding to the target cell, the updated measurement configuration corresponding to the target cell, and the indication identification of the CPC execution condition for determining to use MN configuration.

Based on the above-described CPC configuration to be triggered by MN for cell 2 and the CPC configuration to be triggered by source SN for cells 1, 5, the source SN sends a response message to MN, including: PCI and/or frequency point information of the cells 1 and 5, confirming indication identification of CPC execution conditions configured by using a source SN aiming at the cells 1 and 5; PCI and/or frequency point information of the cell 2, confirming a source SN aiming at the cell 2; updated measurement configuration and/or execution conditions. Also for example: the source SN sends a response message to the MN, which includes: at least one of an SN identifier corresponding to the target SN 1, a measurement configuration of the updated target SN 1, an updated execution condition, an indication identifier for confirming the CPC execution condition configured by the MN, and the like; still other embodiments are similar to this and are not described here in detail to avoid repetition.

Example 5: and determining a second candidate cell of the MN triggering CPC configuration when the MN triggers CPC configuration and interaction between the MN and the corresponding target SN is completed.

As based on the above example, the MN finds cells 1, 2 in which the target SN 1 is configured in both the second candidate cell and the candidate cell recommended by the source SN.

If the MN determines to adopt the CPC configuration triggered by the MN, excluding the cells which are the same as the CPC candidate cells of the CPC configuration triggered by the MN from the candidate cells provided by the source SN (namely deleting a first candidate cell overlapped with a second candidate cell contained in the second cell set from the first cell set), and sending a second SN adding request message to target SN nodes where the rest candidate cells except the first candidate cell in the first cell set are located; wherein the second SN addition request information carries cell information of the remaining candidate cells, but does not carry cell information of the first candidate cell.

Or, the MN excludes the target SN node where the same cell as the second candidate cell is located from the candidate cells provided by the source SN (i.e., deletes the identifier of the target SN corresponding to the first candidate cell overlapped with the second candidate cell included in the second cell set from the first cell set), and sends the second SN addition request message to the target SNs corresponding to the remaining candidate cells (i.e., the remaining target SNs) in the first cell set except for the first candidate cell, respectively, while the MN does not send the SN addition request message to the target SN where the first candidate cell is located.

Or, the MN sends a first SN addition request message to a target SN corresponding to an alternative cell included in the first cell set, where the first SN addition request message includes cell information of each alternative cell in the first cell set.

When the MN determines that the first candidate cell triggered by the source SN to trigger CPC configuration and the second candidate cell contained in the second cell set overlap according to the response message fed back by the target SN for the SN addition request message, the MN sends second indication information to the source SN so as to indicate the source SN to adopt the CPC configuration triggered by the MN for the target cell.

Example 6: and determining a second candidate cell of the MN triggering CPC configuration when the MN triggers CPC configuration and interaction between the MN and the corresponding target SN is completed.

For example, if the target SN1 determines that the source SN is selected for cell 1 to configure the CPC and the MN is selected for cell 2, the target SN1 carries in the response message the indication information of the CPC configuration triggered by the source SN for cell 1 and the indication information of the CPC configuration triggered by the MN for cell 2. The indication information of CPC configuration triggered by using a source SN for the cell 1 includes: PCI and/or frequency point information of the cell 1, and indication identification of CPC execution conditions configured by using a source SN for the cell 1; the indication information of the CPC configuration triggered by the MN for the cell 2 includes: cell 2's PCI and/or frequency point information, indication identification of CPC execution conditions configured for cell 2 using MN. Of course, as a further embodiment, the target SN1 may also determine that the source SN is selected for each of the cells 1, 2 to configure CPC, and then the target SN1 carries in the response message indication information of CPC configuration triggered by using the source SN for the cells 1, 2; or the target SN1 may also determine that MN is selected for both cells 1 and 2 to configure CPC, and the response message of the target SN1 carries indication information of CPC configuration triggered by MN for cells 1 and 2, which is not limited in this embodiment of the present application. When the MN determines that the first candidate cell of which the source SN triggers CPC configuration is overlapped with the second candidate cell contained in the second cell set according to the response message fed back by the target SN aiming at the first indication information, the MN sends second indication information to the source SN so as to instruct the source SN to adopt the CPC configuration triggered by the MN and/or the CPC configuration triggered by the SN aiming at the target cell.

Based on the above target SN 1 determining to select the source SN for cell 1 to configure CPC, for example, MN for cell 2 to select MN to configure CPC, MN sends second indication information to the source SN carrying indication information that MN triggered CPC configuration is to be adopted for cell 2. The indication information of the CPC configuration triggered by the MN to be adopted for the cell 2 comprises the following steps: cell 2's PCI and/or frequency point information, indication identification of CPC execution conditions configured for cell 2 using MN. Optionally, the indication information of CPC configuration triggered by source SN for cells 1, 5 may also be carried. The indication information of the CPC configuration triggered by the source SN to be adopted for the cells 1 and 5 includes: PCI and/or frequency point information of cells 1, 5, indication identification of CPC execution conditions configured using source SN for cells 1, 5.

Based on the above target SN 1 determining to select a source SN for cell 1 to configure CPC, selecting MN for cell 2, the source SN sends a response message to MN, for example, comprising: PCI and/or frequency point information of the cells 1 and 5, confirming indication identification of CPC execution conditions configured by using a source SN aiming at the cells 1 and 5; PCI and/or frequency point information of the cell 2, confirming a source SN aiming at the cell 2; updated measurement configuration and/or execution conditions. Also for example: the source SN sends a response message to the MN, which includes: at least one of an SN identifier corresponding to the target SN 1, a measurement configuration of the updated target SN 1, an updated execution condition, an indication identifier for confirming the CPC execution condition configured using the MN, and the like.

As shown in fig. 2, the embodiment of the present invention further provides a cell processing method applied to a master node MN, the method includes the following steps:

step 21: and sending a first message to the source SN, wherein the first message carries third indication information related to each cell contained in a second cell set, and the second cell set contains second candidate cells of CPC configuration between SNs triggered by the MN.

In this embodiment, the MN may send a first message to the source SN when the MN triggers CPC configuration between SNs.

Optionally, the first message may carry one or more indication information (i.e. third indication information) related to the second candidate cell for indicating CPC configuration between SNs triggered by the MN, where the third indication information includes at least one of the following:

PCI of the second candidate cell;

cell frequency point information of the second candidate cell;

an identification (T-SN ID) of a target SN where the second candidate cell is located;

CPC execution conditions configured by the MN.

Correspondingly, the source SN receives a first message sent by the master node MN, and determines an alternative cell triggering CPC configuration among the SNs according to the first message, wherein the alternative cell is not overlapped with a second candidate cell contained in the second cell set.

The first message carries third indication information related to each cell contained in a second cell set, and the second cell set contains second candidate cells configured by CPC (Condition changing) of a main serving cell of a secondary cell group between SNs triggered by the MN.

Optionally, according to the first message, an alternative cell triggering CPC configuration between SNs is determined, where the alternative cell and a second candidate cell included in the second cell set do not overlap, and may be that when the source SN determines CPC configuration between the triggered SNs, the second candidate cell triggering CPC configuration between SNs indicated in the first message is not selected as an alternative cell of the second candidate cell, and/or a target SN where the second candidate cell is located is not configured as an alternative target SN of the second candidate cell, so that when the CPC configured between the MN triggered SNs and the CPC configured between the source SNs coexist, it can be ensured that the CPC candidate cell configured between the MN triggered SNs and the CPC candidate cell configured between the source SNs are different, thereby avoiding configuring multiple CPCs for the same candidate cell on the network side, reducing network and air interface burden, and also avoiding performing redundant measurement on the UE side, and reducing power consumption overhead.

Example 7: and when CPC configuration between the SNs triggered by the MN is carried out, cell information of the configured candidate cells is sent to the source SN.

Specifically, when the MN does not receive the CPC request triggered by the source SN, the MN sends a first message to the source SN to indicate a second candidate cell of the CPC configuration between the MN-triggered SNs to the source SN.

For example, if the MN triggers the second candidate cell of CPC configuration between SNs: cell 1, cell 2, cell 3; wherein, the cells 1 and 2 correspond to the target SN 1, and the cell 3 corresponds to the target SN 2. The MN sends a first message to the S-SN, the first message including: at least one of the PCI of the cell 1, 2, 3, the cell frequency point information of the cell 1, 2, 3, the ID of the target SN 1, 2, and the indication information of the MN configured with the CPC.

The source SN receives a first message sent by the MN, and determines a second candidate cell and/or a target SN where the second candidate cell is located, which is triggered by the MN and is configured by CPC (physical channel configuration) between the SNs, based on at least one of PCI (physical channel) of the second candidate cell, cell frequency point information of the second candidate cell and identification of the target SN where the second candidate cell is located in the first message.

Optionally, when the source SN triggers CPC configuration between SNs, the determined second candidate cell of CPC configuration between SNs triggered by the MN is not configured as an alternative cell, and/or a target SN where the second candidate cell is located is not configured as an alternative target SN.

Based on the above, if the source SN receives the first message, and determines that the CPC between SNs triggered by the MN configures cells 1, 2 of the target SN1, and cell 3 of the target SN 2 as the second candidate cell. When the source SN determines to trigger CPC configuration between SNs, the following operations may be performed: when the source SN configures the alternative target SN or the alternative cell, the target SN1 and the target SN 2 are eliminated as the alternative target SNs; or the S-SN still configures the target SN1 as an alternative target SN, but does not select cells 1 and 2 of the SN1 as alternative cells thereof, so that CPC candidate cells configured between the SNs triggered by the MN and CPC candidate cells configured between the SNs triggered by the source SN can be ensured to be different, and the situation that the target SN is possibly repeatedly configured for the overlapped cells 1 and 2 can be effectively avoided, so that network and air interface burden is reduced, redundant measurement is avoided to be executed at the UE side, and power consumption cost is reduced.

Of course, as a further embodiment, when the source SN configures the candidate target SN or the candidate cell, a partially overlapped cell may be excluded, for example, the S-SN still configures the target SN1 as its candidate target SN, but does not select cell 1 or cell 2 of the SN1 as its candidate cell, so the S-SN may exclude the partially overlapped cell from the second candidate cell provided by the MN as its candidate cell, so as to avoid that the target SN may be configured repeatedly for the overlapped partial cell, so as to reduce network and air interface burden, and avoid that the UE side performs redundant measurement, and reduce power consumption overhead thereof. Of course, it should be noted that, in the above embodiment of the present application, the scheme related to excluding the target SN where the overlapped cell is located may also be that all or part of the target SNs where the overlapped cell is located are excluded, which is similar to the above embodiment, and is not repeated here.

Optionally, the MN sends the first message to the source SN, which may also be sent when the MN triggers CPC configuration between SNs and does not receive the first set of cells sent by the source SN. Specifically, the embodiment of the invention also provides a cell processing method, which comprises the following steps:

when the MN triggers CPC configuration among the SNs and a first cell set sent by the source SN is not received, a first message is sent to the source SN;

when the MN receives a first cell set sent by a source auxiliary node SN, determining whether the first cell set and a second cell set are overlapped according to cell information of alternative cells contained in the first cell set, and processing each cell in the first cell set and the second cell set according to a determination result.

The first cell set contains cell information of alternative cells, wherein the alternative cells are cells configured by primary service cell condition change CPC of secondary cell groups between SNs triggered by source SNs; the second cell set includes second candidate cells of CPC configuration between SNs triggered by the MN.

Specific embodiments can refer to embodiments 1 to 7 above, and in order to avoid repetition, the solution can ensure that, when the CPC configured between the SNs triggered by the MN and the CPC configured between the SNs triggered by the source SN coexist, the CPC candidate cells configured between the SNs triggered by the MN and the CPC candidate cells configured between the SNs triggered by the source SN are different, so as to avoid that the network side configures multiple sets of CPC configurations for the same candidate cell, so as to reduce the burden of the network and the air interface, and also avoid that the UE side performs redundant measurement, and reduce the power consumption overhead thereof.

The network device according to the embodiment of the present application may be a base station, where the base station may include a plurality of cells for providing services for a terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application.
