Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a cell processing method and device, a master node, a source secondary node and a target secondary node. BACKGROUND

[0002] The master node (MN) triggered conditional primary secondary cell (PSCell) change (CPC) is set by the MN to set the candidate cells and the corresponding execution conditions, while in the scenario of the secondary node (SN) triggered CPC, the setting of the candidate cells and the execution conditions is completed by the source SN (or S-SN). When the MN triggered CPC and the SN triggered CPC coexist, the candidate cell (candidate cell) selected by the MN triggered CPC and the candidate cell of the SN triggered CPC may be the same, which will cause the network side to configure multiple sets of CPC configurations for the same candidate cell, increase the network and air interface burden, and possibly cause the user equipment (UE) to perform redundant measurements, increase the power consumption overhead.

[0206] The above technical solution of the present application has the following advantages:

[0207] In this embodiment of the invention, a first cell set containing candidate cell information sent by a source SN is received. Based on the candidate cell information contained in the first cell set, it is determined whether the second candidate cells in the CPC configuration between the MN-triggered SNs contained in the second cell set overlap. Based on the determination result, each cell in the first cell set and the second cell set is processed. When CPCs configured between MN-triggered SNs and CPCs configured between the source SNs coexist, it can be ensured that the CPC candidate cells configured between MN-triggered SNs and CPC candidate cells configured between the source SNs are different. This avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing network and air interface burden. It can also avoid redundant measurements performed on the UE side, reducing its power consumption. Attached Figure Description

[0219] To make the technical problems to be solved by the present application, technical solutions and advantages clearer, specific embodiments will be described in detail below with reference to the drawings. In the following description, specific details such as specific configurations and components are provided only to help a comprehensive understanding of embodiments of the present application. Therefore, it should be apparent to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. In addition, descriptions of known functions and configurations are omitted for clarity and conciseness.

[0220] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0221] In various embodiments of the present application, it should be understood that the size of the serial number of the following processes does not mean the order of execution, and the execution order of the processes should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0222] In addition, the terms "system" and "network" are often used interchangeably herein.

[0223] The technical solutions provided by the embodiments of the present application can be applied to various systems, especially 5G systems. For example, the applicable systems can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, and the like. The various systems all include terminal devices and network devices. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like.

[0224] The network device and the terminal device can each use one or more antennas for multi-input multi-output (MIMO) transmission, which can be single user MIMO (SU-MIMO) or multiple user MIMO (MU-MIMO). According to the shape and number of root antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission.

[0225] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the following three cases: A exists alone, A and B exist together, and B exists alone. The character " / " generally represents that the associated objects before and after it are in an "or" relationship.

[0226] In this embodiment of the invention, "first cell set" and "second cell set" are involved. Here, "first" and "second" do not indicate order, but are only used to distinguish whether the information generation subject is the source SN or the MN. Similarly, "first" and "second" in "first candidate cell" and "second candidate cell" are used to distinguish whether the candidate cell is triggered by the source SN to configure CPC or the candidate cell is triggered by the MN to configure CPC.

[0227] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0228] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0229] Currently, conditional handover (CHO) and intra-SN conditional PSCell change (intra-SNCPC without MN participation) are introduced in communication systems to improve robustness during handover or PSCell change.

[0230] In addition, it will further introduce intra-SN conditional PSCell change (MN-triggered intra-SN CPC), intra-SN conditional PSCell change (MN-involved intra-SN CPC), inter-SN conditional PSCell change (MN-triggered inter-SN CPC), inter-SN conditional PSCell change (SN-triggered inter-SN CPC), and conditional PSCell addition (CPA).

[0231] For a CPC initiated by the MN, the MN sends the selected candidate cells to the target SN (or T-SN) via inter-node messages. The T-SN selects the corresponding CPC candidate cells from the candidate cells recommended by the MN and generates the corresponding reconfiguration message to feed back to the MN. The MN sets the corresponding execution conditions for the CPC candidate cells, and then the MN completes the matching of the execution conditions of these CPC candidate cells and their corresponding reconfiguration messages, and sends them to the UE through Radio Resource Control (RRC) reconfiguration messages.

[0232] For Inter-SN CPC initiated by the SN, the S-SN sets the corresponding execution conditions for the candidate cells and sends the selected candidate cells and execution conditions to the MN via inter-node messages. The MN then provides the candidate cells to the T-SN, which selects CPC candidate cells and generates reconfiguration messages for them, delivering them to the MN. Finally, the MN matches the execution conditions of the CPC candidate cells with their corresponding reconfiguration messages and sends them to the UE via RRC reconfiguration messages.

[0233] For intra-SN CPC initiated by SN, S-SN sets its candidate CPC cells and generates corresponding reconfiguration messages and execution conditions. Then, it matches these execution conditions with the reconfiguration messages of their corresponding CPC cells, carries them in the RRC reconfiguration message on the SN side, and transmits them to the UE through the MN side. Alternatively, when Signalalling Radio Bearer 3 (SRB3) is configured, it can be directly transmitted to the UE through the SN side.

[0234] When a UE receives a conditional reconfiguration, it does not immediately perform a handover, PSCell change, or PSCell addition as in traditional handover, PSCell change, or PSCell addition. Instead, it saves the received configuration and measures and evaluates the candidate cells in the configuration until a cell that meets the execution conditions of the CHO / CPA / CPC configuration is found. Then, the UE executes the reconfiguration message corresponding to that cell stored in the memory and performs the corresponding handover, PSCell change, or PSCell addition process. This completes downlink synchronization and triggers a random access procedure to access the target primary serving cell (PCell) or PSCell.

[0235] In scenarios where CPC triggered by MN and CPC triggered by SN coexist, the candidate cell (alternate cell) selected by CPC triggered by MN and the candidate cell (or alternative cell) selected by CPC triggered by SN are the same. This will lead to the network side configuring multiple CPC configurations for the same candidate cell, increasing the network and air interface burden, and may also cause the user equipment (UE) to perform redundant measurements, increasing power consumption.

[0236] The terminal devices involved in the embodiments of this application can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0237] This application provides a cell processing method, apparatus, master node, source auxiliary node, and target auxiliary node to address the problem that when CPC triggered by MN and CPC triggered by SN coexist, the network side may configure multiple CPC configurations for the same candidate cell, which may increase network burden and UE functional overhead.

[0238] like Figure 1 As shown, an embodiment of the present invention provides a cell processing method applied to a master node MN, which may specifically include the following steps:

[0239] Step 11: Receive the first cell set sent by the source SN.

[0240] The first cell set includes cell information of candidate cells, which are cells configured by the CPC of the primary serving cell condition change between the secondary cell groups of the source SN.

[0241] Optionally, when the source SN determines that it needs to trigger CPC configuration between SNs, it can send an SN ChangeRequired information message to the MN, which carries the cell information of its recommended cell (wherein the cell can be called a candidate cell). For example, the cell information may include its recommended candidate cell and / or the execution conditions corresponding to triggering CPC configuration, etc. The embodiments of the present invention are not limited thereto.

[0242] Optionally, before the MN receives the first cell set transmitted by the source SN, the method further includes:

[0243] Send a first message to the source SN, the first message carrying third indication information related to each cell in the second cell set, the second cell set including the second candidate cells of CPC configuration between SNs triggered by MN.

[0244] For a description of the third instruction information, please refer to the content described in the subsequent embodiments; it will not be described in detail here.

[0245] Thus, assuming that the source SN receives the first message sent by the MN before performing CPC configuration between SNs, the candidate cells included in the first cell set sent to the MN in step 101 will not overlap with the second candidate cells included in the second cell set.

[0246] Suppose 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 cell set to the MN. Then the source SN can update the candidate cells included in the first cell set based on the first message to ensure that the candidate cells included in the updated first cell set do not overlap with the second candidate cells included in the second cell set.

[0247] Assuming that the source SN did not receive the first message sent by the MN before performing CPC configuration between SNs, and also did not receive the first message sent by the MN before sending the first cell set to the MN, then the source SN sends the first cell set to the MN. The first cell set here is the first cell set recorded in step 11.

[0248] Step 12: Based on the cell information of the candidate cells included in the first cell set, determine whether they overlap with the cells included in the second cell set.

[0249] The second cell set includes second candidate cells for CPC configuration between SNs triggered by the MN.

[0250] Optionally, the second candidate cell for CPC configuration between SNs triggered by the MN included in the second cell set may refer to the cell for CPC configuration triggered by the MN when the MN triggers CPC configuration and has completed interaction with the corresponding target SN.

[0251] For example, when MN triggers CPC configuration, MN can send its selected cell (which can be called a candidate cell) to the target SN (or T-SN) through inter-node messages. The target SN selects the corresponding CPC configuration cell (which can be called a candidate cell) from the candidate cells recommended by MN and generates the corresponding reconfiguration message to feed back to MN. That is, after MN triggers CPC configuration and has completed the interaction with the corresponding target SN, it determines the second candidate cell.

[0252] Optionally, determining whether cells in the first cell set overlap with cells in the second cell set based on cell information of candidate cells in the first cell set may include: determining whether candidate cells in the first cell set overlap with second candidate cells in the second cell set; or, it may also include: determining whether first candidate cells in the first candidate cell set, based on the source SN-triggered inter-SN CPC configuration determined by the first cell set, overlap with second candidate cells in the second cell set. The following will further explain this in conjunction with embodiments.

[0253] Furthermore, it should be noted that if step 11 above is triggered before the interaction between MN and the corresponding target SN is completed (i.e. before the second candidate cell for MN's CPC configuration is determined), and MN has determined the candidate cell for its CPC configuration, then the cells included in the second cell set can be understood as the candidate cells for MN's CPC configuration.

[0254] Further, determining whether cells in the first cell set overlap with cells in the second cell set based on cell information of candidate cells in the first cell set may include: determining whether candidate cells in the first cell set overlap with candidate cells in the second cell set; or, it may also include: determining whether first candidate cells in the first candidate cell set of the inter-SN CPC configuration triggered by the source SN determined by the first cell set overlap with candidate cells in the second cell set. The specific method for determining this overlap and the corresponding processing based on the determination result are similar to the case where the second cell set contains second candidate cells in the inter-SN CPC configuration triggered by the MN. To avoid repetition, the following embodiments will describe the case where the second cell set contains second candidate cells.

[0255] Step 13: Based on the determined results, process each cell in the first cell set and the second cell set.

[0256] Optionally, the determination result can be: determining whether the cells in the second cell set overlap with the cells in the first cell set based on the cell information of the candidate cells included in the first cell set, or determining whether the cells in the second cell set overlap with the cells in the first candidate cell set included in the first candidate cell set of the inter-SN CPC configuration triggered by the source SN determined by the first cell set.

[0257] If step 12 determines that there is overlap, then MN identifies the cells that overlap between the first cell set and the second cell set as overlapping cells, and determines the execution conditions for these overlapping cells. Specifically, MN determines whether a particular overlapping cell uses the CPC execution conditions configured by MN or the CPC execution conditions configured by the source SN.

[0258] In this embodiment, a first cell set containing candidate cell information sent by the source SN is received, and based on the candidate cell information contained in the first cell set, it is determined whether the second candidate cell in the CPC configuration between the MN-triggered SNs contained in the second cell set overlaps with the CPC configuration between the MN-triggered SNs. Based on the determination result, each cell in the first cell set and the second cell set is processed to ensure that when the CPC configuration between the MN-triggered SNs and the CPC configuration between the source SNs coexist, the CPC candidate cells between the MN-triggered SNs and the CPC configuration between the source SNs are different. This avoids configuring multiple CPC configurations for the same candidate cell on the network side, reducing network and air interface burden, and also avoids redundant measurements on the UE side, reducing its power consumption.

[0259] Since the embodiments described in this application involve CPC configuration between MN-triggered SNs and CPC configuration between source SN-triggered SNs, and the CPC configuration between source SN-triggered SNs needs to be forwarded to the target SN through MN, the specific implementation may include, but is not limited to, the following situations:

[0260] The first scenario is as follows: First, MN triggers CPC configuration between SNs to obtain a second cell set, which contains cell information of the CPC cells configured between SNs triggered by MN; second, it receives a first cell set of CPC configuration between SNs triggered by the source SN, which contains cell information of the CPC candidate cells configured between SNs triggered by the source SN.

[0261] In the first case, step 12 determines whether the candidate cells included in the first cell set overlap with the cells included in the second cell set.

[0262] If there is overlap, in step 13, the MN can delete the overlapping cells (hereinafter referred to as overlapping cells). This deletion can include deleting the cell identifier of the overlapping cell or deleting the target SN information corresponding to the overlapping cell. If the information of the candidate cells included in the first cell set is deleted, then the MN sends a second SN add request message to the target SNs corresponding to the remaining candidate cells in the first cell set. The second SN add request message contains the cell information of the remaining candidate cells in the first cell set. Afterwards, the MN receives the first candidate cells selected for the remaining candidate cells from each target SN and sends the first candidate cell and the second candidate cell to the UE.

[0263] Optionally, if there is overlap, in step 13, the MN sends a first SN add request message to the target SNs corresponding to the candidate cells included in the first cell set. The first SN add request message contains cell information of each candidate cell in the first cell set. Then, the MN receives the first candidate cell information fed back by each target SN. At this time, based on the received first candidate cells, the MN again checks whether the first candidate cells overlap with the second candidate cells included in the second cell set. If there is overlap, the MN determines the overlapping candidate cells and sets execution conditions for the overlapping candidate cells, and then sends the cell information with redefined execution conditions to the UE.

[0264] It should be noted that the deletion of overlapping cells by MN can be done by deleting overlapping cells from the first cell set, thus ensuring that the target SN will not select overlapping cells when selecting the first candidate cell, i.e., the execution conditions for determining overlapping cells are configured using MN; or it can be done by deleting overlapping cells from the second cell set, i.e., the execution conditions for determining overlapping cells are configured using the source MN.

[0265] If there is no overlap, the MN sends a first SN add request message to the target SN corresponding to the candidate cells included in the first cell set. The target SN selects the first candidate cell from the first cell set and feeds it back to the MN. Then, the MN sends the first candidate cell and the second candidate cell to the UE.

[0266] The second scenario: Before the CPC configuration between SNs triggered by the MN is obtained to obtain the second cell set, the first cell set of CPC configuration between SNs triggered by the source SN is received. Here, the first cell set contains cell information of CPC candidate cells for CPC configuration between SNs triggered by the source SN.

[0267] For the second scenario, steps 12 and 13 can be performed in the same way as for the first scenario. Alternatively, before performing step 12, the MN can send a first SN add request message to the target SNs corresponding to the candidate cells in the first cell set. This first SN add request message contains cell information for each candidate cell in the first cell set. Afterward, the MN receives the first candidate cell information from each target SN. In this case, in step 12, the MN will check whether the first candidate cell overlaps with the second candidate cell in the second cell set based on the received first candidate cell information. If there is overlap, in step 13, the MN directly determines the execution conditions for the overlapping cells and then sends the cell information with redefined execution conditions to the UE. If there is no overlap, the MN sends the first and second candidate cells to the UE.

[0268] Optionally, determining whether there is overlap between the candidate cells included in the first cell set and the cells included in the second cell set, based on the cell information of the candidate cells included in the first cell set, includes:

[0269] Determine whether the candidate cells included in the first cell set overlap with the second candidate cells included in the second cell set.

[0270] For example, when the source SN determines that it needs to trigger CPC configuration between SNs, it can send an SN Change Required message to the MN, which carries the cell information of its recommended candidate cells. This cell information may include the recommended candidate cells and / or the execution conditions corresponding to triggering CPC configuration. When the MN receives the SN Change Required message sent by the source SN, it can determine whether its recommended candidate cells overlap with the second candidate cells included in the second cell set based on the cell information of the candidate cells recommended by the source SN.

[0271] Optionally, determining whether cells in the first cell set overlap with cells in the second cell set based on cell information of candidate cells included in the first cell set includes:

[0272] Based on the first cell set, determine the first candidate cell set for inter-SN CPC configuration triggered by the source SN;

[0273] Determine whether the cell information of the first candidate cells included in the first candidate cell set overlaps with the cell information included in the second cell set.

[0274] Specifically, based on the first cell set, determining the first candidate cell set for the inter-SN CPC configuration triggered by the source SN includes: sending a first SN add request message to the target SN corresponding to the candidate cells included in the first cell set, wherein the first SN add request message contains cell information of each of the candidate cells in the first cell set;

[0275] The target SN receives a first candidate cell sent by the target SN, the first candidate cell being determined by the target SN based on the candidate cells carried in the first SN add request message.

[0276] Optionally, determining whether cells in the first cell set overlap with cells in the second cell set based on cell information of candidate cells included in the first cell set includes:

[0277] Send a first SN add request message to the target SN corresponding to the candidate cells included in the first cell set. The first SN add request message contains cell information of each candidate cell in the first cell set.

[0278] The target SN receives a first candidate cell sent by the target SN, wherein the first candidate cell is determined by the target SN based on the candidate cells carried in the first SN add request message;

[0279] Determine whether the first candidate cell overlaps with the second candidate cell included in the second cell set.

[0280] For example, when a source SN determines that it needs to trigger CPC configuration between SNs, it can send an SN Change Required message to the MN, carrying cell information of its recommended candidate cells. This cell information may include the recommended candidate cells and / or the execution conditions corresponding to triggering CPC configuration. Upon receiving the SN Change Required message from the source SN, the MN can send a first SN add request message to the target SN corresponding to the candidate cells recommended by the source SN. The first SN add request message may include cell information of all the candidate cells. The target SN can then select a corresponding candidate cell (i.e., the first candidate cell) from the candidate cells and send it to the MN.

[0281] In this way, the MN receives the first candidate cell sent by the target SN. The first candidate cell is determined by the target SN based on the candidate cells carried in the first SN add request message. The MN can also determine whether the first candidate cell overlaps with the second candidate cell contained in the second cell set.

[0282] Optionally, based on the determination result, each cell in the first cell set and the second cell set is processed, including:

[0283] If it is determined that there is an overlap with the second candidate cells included in the second cell set, then one or more of the following operations are performed:

[0284] A. Delete the first candidate cell from the first cell set that overlaps with the second candidate cell contained in the second cell set, and send a second SN add request message to the target SNs corresponding to the remaining candidate cells in the first cell set. The second SN add request message contains the cell information of the remaining candidate cells. In this embodiment, MN deletes the first candidate cell from the first cell set that overlaps with the second candidate cell contained in the second cell set, and does not carry the cell information of the first candidate cell when sending the second SN add request message to the target SN containing the first candidate cell.

[0285] B. The identifier of the target SN corresponding to the first candidate cell that overlaps with the second candidate cell included in the second cell set is deleted from the first cell set. Then, a second SN addition request message is sent to each of the remaining target SNs corresponding to the first cell set. The second SN addition request message contains cell information of the candidate cells corresponding to the remaining target SNs. In this embodiment, MN deletes the identifier of the target SN corresponding to the first candidate cell that overlaps with the second candidate cell included in the second cell set from the first cell set, and MN does not send SN addition request messages to the target SNs corresponding to the first candidate cells.

[0286] It should be noted that since the correspondence between candidate cells and target SNs may be many-to-one, this means that after identifying overlapping first candidate cells, the target SN corresponding to those overlapping first candidate cells may correspond to more than one first candidate cell. In this case, deleting the target SN means excluding multiple candidate cells corresponding to that target SN. For example, the candidate cells corresponding to target SN1 include C1, C2, and C3; if C2 is determined to be an overlapping cell, deleting target SN1 means that C1 and C3 are also deleted simultaneously.

[0287] C. Send a first SN add request message to the target SN corresponding to the candidate cells included in the first cell set. The first SN add request message contains cell information of each candidate cell in the first cell set.

[0288] Example 1: When at least one MN-triggered CPC configuration has the same second candidate cell as the candidate cell of the source SN-triggered CPC configuration (i.e., it is determined that the candidate cells included in the first cell set overlap with the second candidate cells included in the second cell set), the MN can directly decide to adopt the MN-triggered CPC configuration and / or the source SN-triggered CPC configuration.

[0289] It should be noted that the CPC configuration triggered here can be understood as the CPC execution conditions configured above.

[0290] Specifically, when the MN triggers CPC configuration and has completed interaction with the corresponding target SN, the second candidate cell for CPC configuration triggered by the MN is determined.

[0291] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0292] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0293] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0294] After receiving the SN Change Required message from the source SN, the MN obtains the candidate cells recommended by the source SN and the corresponding candidate target SNs. The MN discovers that some of the candidate cells provided by the source SN are the same as the second candidate cells in the CPC configuration between the MN and the SN, and / or have the same target SN node (i.e., the candidate cells recommended by the source SN overlap with the second candidate cells configured by the MN, or the target SN corresponding to the candidate cells recommended by the source SN overlaps with the target SN corresponding to the second candidate cells configured by the MN).

[0295] Based on the above example, if the MN discovers that both the second candidate cell and the candidate cells recommended by the source SN are configured with cells 1 and 2 of target SN1, then the MN can directly decide to adopt the CPC configuration triggered by the MN and / or the CPC configuration triggered by the source SN. Taking the MN's decision to adopt the CPC configuration triggered by the MN as an example, the MN can execute one or more of the following methods:

[0296] Method 1: The MN excludes cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured by the CPC triggered by the MN (i.e., deletes the first candidate cell that overlaps with the second candidate cell contained in the second cell set from the first cell set), and sends a second SN add request message to the target SN node where the remaining candidate cells in the first cell set are located, excluding the first candidate cell; wherein the second SN add request message carries the cell information of the remaining candidate cells, but does not carry the cell information of the first 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 guaranteed that the CPC candidate cells configured between the MN-triggered SNs and the CPC candidate cells configured between the source SNs are different, and / or avoid the network side configuring multiple sets of CPC configurations for the same candidate cell, so as to reduce the network and air interface burden, and also avoid the UE side performing redundant measurements, reducing its power consumption.

[0297] Optionally, the MN can exclude some cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured by the CPC triggered by the MN. For example, if the MN determines to take CPC configuration triggered by the MN for cell 1, then the MN excludes cell 1 from the candidate cells provided by the source SN. That is, the MN sends a second SN add request message to the target SN 1 carrying the cell information of the candidate cells 2 and 5 recommended by the source SN, but not the cell information of cell 1. In this way, the MN can exclude some cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured by the CPC triggered by the MN. This can avoid the target SN from repeatedly configuring the overlapping cell 1, thereby reducing the network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption.

[0298] Optionally, the MN can exclude all cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured in the CPC triggered by the MN. For example, if the MN determines to take the CPC configuration triggered by the MN for cells 1 and 2, then the MN excludes cells 1 and 2 from the candidate cells provided by the source SN. That is, the MN sends a second SN add request message to the target SN 1 carrying the cell information of the candidate cell 5 recommended by the source SN, but not the cell information of cells 1 and 2. This can ensure that the CPC candidate cells configured between the MN and the CPC candidate cells configured between the source SN are different, and can also effectively avoid the target SN from repeatedly configuring the overlapping cells 1 and 2, thereby reducing the network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption.

[0299] Method 2: The MN excludes the target SN node containing the same cell as the second candidate cell from the candidate cells provided by the source SN (i.e., removes the identifier of the target SN corresponding to the first candidate cell that overlaps with the second candidate cell contained in the second cell set from the first cell set), and sends a second SN add request message to the target SNs corresponding to the remaining candidate cells in the first cell set (i.e., the remaining target SNs) excluding the first candidate cell. The MN does not send an SN add request message to the target SN containing the first candidate cell. This ensures that when the CPC configured between SNs triggered by the MN and the CPC configured between SNs triggered by the source SN coexist, the CPC candidate cells configured between SNs triggered by the MN and the CPC candidate cells configured between SNs triggered by the source SN are different, and / or avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing the network and air interface burden, and also avoids the UE side performing redundant measurements, reducing its power consumption.

[0300] Based on the above example, MN excludes target SN 1 from the candidate cells provided by the source SN, that is, MN will not send the SN add request message to target SN 1 for configuring CPC configuration triggered by the source SN.

[0301] 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 can delete the first candidate cell that overlaps with the second candidate cell included in the second cell set from the first cell set, and send a second SN add request message to the target SNs corresponding to the remaining candidate cells in the first cell set. Alternatively, the MN can delete the identifier of the target SN corresponding to the first candidate cell that overlaps with the second candidate cell included in the second cell set from the first cell set, and send a second SN add request message to the remaining target SNs corresponding to the first cell set. This ensures that when the CPC configured between SNs triggered by the MN and the CPC configured between SNs triggered by the source SN coexist, the CPC candidate cells configured between SNs triggered by the MN and the CPC candidate cells configured between SNs triggered by the source SN are different, and / or avoid configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing the network and air interface burden, and also avoiding redundant measurements on the UE side, reducing its power consumption.

[0302] Example 2: When MN triggers CPC configuration and has completed interaction with the corresponding target SN, determine the second candidate cell for MN-triggered CPC configuration.

[0303] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0304] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0305] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0306] After receiving the SN Change Required message from the source SN, the MN obtains the candidate cells recommended by the source SN (i.e., the cells in the first cell set) and the corresponding candidate target SNs. The MN sends a first SN add request message to the target SNs corresponding to the candidate cells in the first cell set. The first SN add request message contains the cell information of each candidate cell in the first cell set.

[0307] For example, MN sends a first SN add request message to target SN 1, which carries cell information of candidate cells 1, 2, and 5 recommended by the source SN and / or the execution conditions of CPC configuration triggered by the source SN for each candidate cell.

[0308] The target SN receives the first SN add request message sent by the MN, selects the first candidate cell for the source SN to trigger CPC configuration from the candidate cells based on the cell information of the candidate cells contained in the first SN add request message, and sends it to the MN.

[0309] Optionally, if the target SN determines that CPC execution conditions have been configured for the first candidate cell, then the first candidate cell is selected as the first candidate cell and sent to the MN. That is, if the target SN determines that the first candidate cell in the candidate cells overlaps with the second candidate cell included in the second cell set, and CPC execution conditions have been configured for the first candidate cell, the target SN can still select the first candidate cell as the first candidate cell. However, 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 load.

[0310] For example, target SN 1 can still select cell 1 and / or cell 2 as the first candidate cell, but will not generate new configuration information for cell 1 and cell 2.

[0311] Optionally, if the target SN determines that CPC execution conditions have been configured for the first candidate cell, the target SN will not select the first candidate cell as the first candidate cell, thereby avoiding the network side from configuring multiple CPC configurations for the same candidate cell, thus reducing the network and air interface burden.

[0312] For example, target SN 1 selects cell 5 as the first candidate cell, but does not select cells 1 and 2 as the first candidate cells.

[0313] The MN receives a first candidate cell set sent by the target SN. The first candidate cell set includes first candidate cells determined by the target SN based on the candidate cells carried in the first SN add request message. Based on the first candidate cell set, the MN determines whether the first candidate cells in the first candidate cell set overlap with the second candidate cells included in the second cell set. Based on the determination result (i.e., the result of determining whether the first candidate cells included in the first candidate cell set of the inter-SN CPC configuration triggered by the source SN overlap with the cells included in the second cell set), the MN processes each cell in the first cell set and the second cell set. This ensures that when the inter-SN CPC configuration triggered by the MN and the inter-SN CPC configuration triggered by the source SN coexist, the CPC candidate cells of the inter-SN CPC configuration triggered by the MN and the CPC candidate cells of the inter-SN CPC configuration triggered by the source SN are different, and / or avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing network and air interface burden. It also avoids redundant measurements on the UE side, reducing its power consumption.

[0314] Optionally, based on the determination result, each cell in the first cell set and the second cell set is processed, including: if it is determined that there is an overlap with the second candidate cell included in the second cell set, then a first indication information is sent to the target SN corresponding to the first candidate cell that overlaps with the second candidate cell included in the second cell set. The first indication information is used to instruct the target SN to perform CPC configuration selection for the first candidate cell. The CPC configuration selection includes the CPC execution conditions configured by the MN, or the CPC execution conditions configured by the source SN.

[0315] The first indication information includes one or more of the following:

[0316] PCI of the first candidate cell;

[0317] The cell frequency information of the first candidate cell;

[0318] The identifier of the target SN corresponding to the first candidate cell;

[0319] CPC execution conditions configured in MN;

[0320] CPC execution conditions configured in the source SN.

[0321] Specifically, when the MN determines that there is an overlap with a second candidate cell included in the second cell set, the MN can instruct the target SN corresponding to the first candidate cell overlapping with the second candidate cell included in the second cell set to select a CPC configuration triggered by the source SN and / or a CPC configuration triggered by the MN. At this time, the target SN receives the first indication information sent by the MN, determines to take the CPC configuration triggered by the source SN and / or the CPC configuration triggered by the MN for the first candidate cell, and sends a response message to the MN regarding the first indication information, wherein the response message contains one or more of the following information:

[0322] PCI of the first candidate cell;

[0323] The cell frequency information of the first candidate cell;

[0324] The identifier of the target SN corresponding to the first candidate cell;

[0325] Indicator identifier for CPC execution conditions configured using MN;

[0326] Indicator identifier for CPC execution conditions configured using the source SN.

[0327] Accordingly, the cell processing method on the MN side further includes:

[0328] Receive a response message sent by the target SN in response to the first indication information, wherein the response message contains one or more of the following information:

[0329] PCI of the first candidate cell;

[0330] The cell frequency information of the first candidate cell;

[0331] The identifier of the target SN corresponding to the first candidate cell;

[0332] Indicator identifier for CPC execution conditions configured using MN;

[0333] Indicator identifier for CPC execution conditions configured using the source SN.

[0334] 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 can instruct the target SN corresponding to the first candidate cell that overlaps with the second candidate cell included in the second cell set to select the CPC configuration triggered by the source SN and / or the CPC configuration triggered by the MN. At this time, the target SN receives the first indication information sent by the MN, determines to take the CPC configuration triggered by the source SN and / or the CPC configuration triggered by the MN for the first candidate cell, and sends a response message to the MN for the first indication information. This ensures that when the CPC configuration between SNs triggered by the MN and the CPC configuration between SNs triggered by the source SN coexist, the CPC candidate cells configured between SNs triggered by the MN and the CPC candidate cells configured between SNs triggered by the source SN are different. This avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing the network and air interface burden, and also avoids the UE side performing redundant measurements, reducing its power consumption.

[0335] Example 3: When at least one MN-triggered CPC configuration has the same second candidate cell as the candidate cell of the source SN-triggered CPC configuration, the MN can request the target SN to select to adopt the source SN-triggered CPC configuration and / or the MN-triggered CPC configuration.

[0336] Specifically, when the MN triggers CPC configuration and has completed interaction with the corresponding target SN, the second candidate cell for CPC configuration triggered by the MN is determined.

[0337] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0338] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0339] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0340] After receiving the SN Change Required message from the source SN, the MN obtains the candidate cells recommended by the source SN and the corresponding candidate target SNs. If the MN discovers that one of the candidate cells provided by the source SN is the same as the second candidate cell in the CPC configuration triggered by the MN for the SN, and / or the target SN where the first candidate cell is located, the MN sends first indication information to the target SN where the first candidate cell is located. The first indication information is used to instruct the target SN to perform CPC configuration selection for the first candidate cell, that is, to instruct the target SN to choose the CPC configuration triggered by the MN and / or the CPC configuration triggered by the SN. The first indication information includes one or more of the following: the PCI of the first candidate cell, the cell frequency information of the first candidate cell, the identifier of the target SN corresponding to the first candidate cell, the CPC execution conditions configured by the MN, and the CPC execution conditions configured by the source SN.

[0341] Based on the above example, if the MN finds that both the second candidate cell and the candidate cells recommended by the source SN are configured with cells 1 and 2 of the target SN, then the MN sends a first indication message to the target SN. This first indication message carries the PCI and / or frequency information of cells 1 and 2, the execution conditions for cells 1 and 2 in the CPC configuration triggered by the MN, and the execution conditions for cells 1 and 2 in the CPC configuration triggered by the source SN.

[0342] The target SN determines the CPC configuration to be triggered by the source SN and / or the CPC configuration to be triggered by the MN for the first candidate cell (e.g., using the CPC configuration triggered by the source SN for the first candidate cell; or using the CPC configuration triggered by the MN for the first candidate cell; or using the CPC configuration triggered by the source SN for some cells in the first candidate cell and the CPC configuration triggered by the MN for others, etc.), and sends a response message to the MN in response to the first indication information. The response message includes one or more of the following: the PCI of the first candidate cell, the cell frequency information of the first candidate cell, the identifier of the target SN corresponding to the first candidate cell, an indication identifier for CPC execution conditions configured using the MN, and an indication identifier for CPC execution conditions configured using the source SN.

[0343] For example, if target SN 1 determines to select source SN to configure CPC for cell 1 and select MN to configure CPC for cell 2, then target SN 1 will carry indication information for CPC configuration triggered by source SN for cell 1 and indication information for CPC configuration triggered by MN for cell 2 in the response message. The indication information for CPC configuration triggered by source SN for cell 1 includes: the PCI and / or frequency information of cell 1, and an indication identifier of the CPC execution conditions configured by source SN for cell 1; the indication information for CPC configuration triggered by MN for cell 2 includes: the PCI and / or frequency information of cell 2, and an indication identifier of the CPC execution conditions configured by MN for cell 2.

[0344] Optionally, Embodiment 3 can be combined with Embodiment 1 to implement the cell processing method of the present invention, so that when CPCs configured between SNs triggered by MN and CPCs configured between SNs triggered by the source SN coexist, the CPC candidate cells configured between SNs triggered by MN and CPC candidate cells configured between SNs triggered by the source SN are different, thereby avoiding the network side from configuring multiple sets of CPC configurations for the same candidate cell, reducing the network and air interface burden, and also avoiding the UE side from performing redundant measurements, reducing its power consumption overhead.

[0345] Optionally, the method further includes: sending second indication information to the source SN, the second indication information containing one or more of the following:

[0346] The PCI of the target cell, wherein the target cell is: a cell in the candidate cells included in the first cell set that overlaps with a second candidate cell included in the second cell set, or a cell in the first candidate cells included in the first candidate cell set that overlaps with a second candidate cell included in the second cell set;

[0347] The target cell's frequency information;

[0348] The identifier of the target SN corresponding to the target cell;

[0349] Indicator identifier for CPC execution conditions configured using MN;

[0350] Indicator identifier for CPC execution conditions configured using the source SN.

[0351] Optionally, the second indication information can be used to instruct the source SN to use MN-triggered CPC configuration and / or source SN-triggered CPC configuration for the target cell. In this case, after receiving the second indication information, the source SN can determine to use MN-triggered CPC configuration and / or source SN-triggered CPC configuration for the target cell; and / or, after receiving the second indication information, the source SN updates the CPC execution conditions corresponding to the target cell according to the second indication information, so as to avoid configuring multiple sets of CPC configurations for the same candidate cell on the network side when MN-triggered CPC configurations and source SN-triggered CPC configurations coexist, thereby reducing network and air interface load.

[0352] Optionally, the source SN may also send a response message to the MN regarding the second indication information. Accordingly, the cell processing method on the MN side further includes: receiving the response message from the source SN regarding the second indication information, the response message containing one or more of the following information:

[0353] PCI of the target cell;

[0354] The target cell's frequency information;

[0355] The identifier of the target SN corresponding to the target cell;

[0356] The updated CPC execution conditions corresponding to the target cell;

[0357] The updated measurement configuration corresponding to the target cell;

[0358] Determine the indicator identifier for CPC execution conditions configured using MN;

[0359] Determine the indicator flag for the CPC execution conditions configured using the source SN.

[0360] It should be noted that the target cell in this embodiment of the invention may be a cell in the first candidate cell set that overlaps with a second candidate cell in the second cell set, or a cell in the candidate cells in the first cell set that overlaps with a second candidate cell in the second cell set. That is, this embodiment can be combined with at least one of the above embodiments. Since the two embodiments are similar, to avoid repetition, the following description is based on the premise that the target cell is a cell in the first candidate cell set that overlaps with a second candidate cell in the second cell set, in conjunction with specific embodiments.

[0361] Example 4: When MN triggers CPC configuration and has completed interaction with the corresponding target SN, determine the second candidate cell for MN-triggered CPC configuration.

[0362] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0363] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0364] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0365] Upon receiving the SN Change Required message from the source SN, the MN can send a first SN Add Request message to the target SN corresponding to the candidate cells recommended by the source SN. This first SN Add Request message may include cell information for all the candidate cells. The target SN can select a corresponding candidate cell (i.e., a first candidate cell) from the candidate cells and send it to the MN. The MN then receives the first candidate cell sent by the target SN, which is determined by the target SN based on the candidate cells carried in the first SN Add Request message. The MN can also determine whether the first candidate cell overlaps with a second candidate cell included in the second cell set.

[0366] When the MN determines that the first candidate cell overlaps with the second candidate cell contained in the second cell set, the MN sends a second indication message to the source SN to instruct the source SN to take CPC configuration triggered by the MN for the target cell.

[0367] Based on the above example, the MN sends a second indication message to the source SN, which carries indication information for the CPC configuration triggered by the MN to be implemented in cell 2. This indication information for the CPC configuration triggered by the MN to be implemented in cell 2 includes: the PCI and / or frequency information of cell 2, and an indication identifier for the CPC execution conditions configured by the MN for cell 2. Optionally, it may also carry indication information for the CPC configuration triggered by the source SN to be implemented in cells 1 and 5. This indication information for the CPC configuration triggered by the source SN to be implemented in cells 1 and 5 includes: the PCI and / or frequency information of cells 1 and 5, and an indication identifier for the CPC execution conditions configured by the source SN for cells 1 and 5. Of course, as another optional embodiment, the MN sends a second indication message to the source SN, which carries indication information for the CPC configuration triggered by the MN to be implemented in cells 1 and 2. Optionally, it may also carry indication information for the CPC configuration triggered by the source SN to be implemented in cell 5, etc., and this embodiment is not limited thereto.

[0368] Alternatively, when the MN determines that the first candidate cell overlaps with the second candidate cell contained in the second cell set, the MN sends a second indication message to the source SN to instruct the source SN to take CPC configuration triggered by the MN for the target SN corresponding to the target cell.

[0369] For example, the MN sends a second instruction message to the source SN. The second instruction message contains: the SN identifier corresponding to the target SN 1, and an instruction identifier for using the CPC execution conditions configured by the MN for the target SN 1.

[0370] The source SN sends a response message to the MN in response to the received second indication information. The response message includes: the PCI of the target cell, the cell frequency information of the target cell, the identifier of the target SN corresponding to the target cell, the updated CPC execution conditions corresponding to the target cell, the updated measurement configuration corresponding to the target cell, and an indication identifier for determining the CPC execution conditions configured by the MN.

[0371] Based on the above examples of CPC configuration triggered by MN for cell 2 and CPC configuration triggered by source SN for cells 1 and 5, the source SN sends a response message to MN, including: PCI and / or frequency information of cells 1 and 5, an indication flag confirming the CPC execution conditions configured by the source SN for cells 1 and 5; PCI and / or frequency information of cell 2, confirmation of the source SN for cell 2; and updated measurement configuration and / or execution conditions. For example, the source SN sends a response message to MN, including at least one of: the SN identifier corresponding to target SN 1, the updated measurement configuration of target SN 1, the updated execution conditions, and an indication flag confirming the CPC execution conditions configured by MN. Other embodiments are similar, and will not be described further here to avoid repetition.

[0372] Example 5: When MN triggers CPC configuration and has completed interaction with the corresponding target SN, determine the second candidate cell for MN-triggered CPC configuration.

[0373] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0374] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0375] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0376] After receiving the SN Change Required message from the source SN, the MN obtains the candidate cells recommended by the source SN and the corresponding candidate target SNs. The MN discovers that some of the candidate cells provided by the source SN are the same as the second candidate cells in the CPC configuration between the MN and the SN, and / or have the same target SN node (i.e., the candidate cells recommended by the source SN overlap with the second candidate cells configured by the MN, or the target SN corresponding to the candidate cells recommended by the source SN overlaps with the target SN corresponding to the second candidate cells configured by the MN).

[0377] Based on the example above, MN found that both the second candidate cell and the candidate cells recommended by the source SN were configured with the target SN1, cells 1 and 2.

[0378] If the MN determines to adopt the CPC configuration triggered by the MN, then it excludes the same CPC candidate cell as the CPC candidate cell in the CPC configuration triggered by the MN from the candidate cells provided by the source SN (i.e., deletes the first candidate cell that overlaps with the second candidate cell contained in the second cell set from the first cell set), and sends a second SN add request message to the target SN node where the remaining candidate cells in the first cell set are located, excluding the first candidate cell; wherein the second SN add request message carries the cell information of the remaining candidate cells, but does not carry the cell information of the first candidate cell.

[0379] Optionally, the MN can exclude some cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured by the CPC triggered by the MN. For example, if the MN determines to take CPC configuration triggered by the MN for cell 1, then the MN excludes cell 1 from the candidate cells provided by the source SN. That is, the MN sends a second SN add request message to the target SN 1 carrying the cell information of the candidate cells 2 and 5 recommended by the source SN, but not the cell information of cell 1. In this way, the MN can exclude some cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured by the CPC triggered by the MN. This can avoid the target SN from repeatedly configuring the overlapping cell 1, thereby reducing the network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption.

[0380] Optionally, the MN can exclude all cells from the candidate cells provided by the source SN that are the same as the CPC candidate cells configured in the CPC triggered by the MN. For example, if the MN determines to take the CPC configuration triggered by the MN for cells 1 and 2, then the MN excludes cells 1 and 2 from the candidate cells provided by the source SN. That is, the MN sends a second SN add request message to the target SN 1 carrying the cell information of the candidate cell 5 recommended by the source SN, but not the cell information of cells 1 and 2. This can ensure that the CPC candidate cells configured between the MN and the CPC candidate cells configured between the source SN are different, and can also effectively avoid the target SN from repeatedly configuring the overlapping cells 1 and 2, thereby reducing the network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption.

[0381] Alternatively, the MN excludes the target SN node containing the same cell as the second candidate cell from the candidate cells provided by the source SN (i.e., removes the identifier of the target SN corresponding to the first candidate cell that overlaps with the second candidate cell contained in the second cell set from the first cell set), and sends a second SN add request message to the target SNs corresponding to the remaining candidate cells in the first cell set (i.e., the remaining target SNs) excluding the first candidate cell, while the MN does not send an SN add request message to the target SN containing the first candidate cell.

[0382] Based on the above example, MN excludes target SN 1 from the candidate cells provided by the source SN, that is, MN will not send the SN add request message to target SN 1 for configuring CPC configuration triggered by the source SN.

[0383] Alternatively, MN sends a first SN add request message to the target SN corresponding to the candidate cells included in the first cell set. The first SN add request message contains cell information of each candidate cell in the first cell set.

[0384] For example, MN sends a first SN add request message to target SN 1, which carries cell information of candidate cells 1, 2, and 5 recommended by the source SN and / or the execution conditions of CPC configuration triggered by the source SN for each candidate cell.

[0385] When the MN determines, based on the response message of the request message from the target SN to the SN, that the first candidate cell for CPC configuration triggered by the source SN overlaps with the second candidate cell included in the second cell set, the MN sends a second indication message to the source SN to instruct the source SN to take CPC configuration triggered by the MN for the target cell.

[0386] Based on the above example, the MN sends a second indication message to the source SN, which carries indication information for the CPC configuration triggered by the MN to be implemented in cell 2. This indication information for the CPC configuration triggered by the MN to be implemented in cell 2 includes: the PCI and / or frequency information of cell 2, and an indication identifier for the CPC execution conditions configured by the MN for cell 2. Optionally, it may also carry indication information for the CPC configuration triggered by the source SN to be implemented in cells 1 and 5. This indication information for the CPC configuration triggered by the source SN to be implemented in cells 1 and 5 includes: the PCI and / or frequency information of cells 1 and 5, and an indication identifier for the CPC execution conditions configured by the source SN for cells 1 and 5. Of course, as another optional embodiment, the MN sends a second indication message to the source SN, which carries indication information for the CPC configuration triggered by the MN to be implemented in cells 1 and 2. Optionally, it may also carry indication information for the CPC configuration triggered by the source SN to be implemented in cell 5, etc., and this embodiment is not limited thereto.

[0387] Alternatively, when the MN determines that the first candidate cell overlaps with the second candidate cell contained in the second cell set, the MN sends a second indication message to the source SN to instruct the source SN to take CPC configuration triggered by the MN for the target SN corresponding to the target cell.

[0388] For example, the MN sends a second instruction message to the source SN. The second instruction message contains: the SN identifier corresponding to the target SN 1, and an instruction identifier for using the CPC execution conditions configured by the MN for the target SN 1.

[0389] The source SN sends a response message to the MN in response to the received second indication information. The response message includes: the PCI of the target cell, the cell frequency information of the target cell, the identifier of the target SN corresponding to the target cell, the updated CPC execution conditions corresponding to the target cell, the updated measurement configuration corresponding to the target cell, and an indication identifier for determining the CPC execution conditions configured by the MN.

[0390] Based on the above examples of CPC configuration triggered by MN for cell 2 and CPC configuration triggered by source SN for cells 1 and 5, the source SN sends a response message to MN, including: PCI and / or frequency information of cells 1 and 5, an indication flag confirming the CPC execution conditions configured by the source SN for cells 1 and 5; PCI and / or frequency information of cell 2, confirmation of the source SN for cell 2; and updated measurement configuration and / or execution conditions. For example, the source SN sends a response message to MN, including at least one of: the SN identifier corresponding to target SN 1, the updated measurement configuration of target SN 1, the updated execution conditions, and an indication flag confirming the CPC execution conditions configured by MN. Other embodiments are similar, and will not be described further here to avoid repetition.

[0391] Example 6: When MN triggers CPC configuration and has completed interaction with the corresponding target SN, determine the second candidate cell for MN-triggered CPC configuration.

[0392] For example, the second candidate cells for CPC configuration triggered by MN include: cell 1, cell 2, and cell 3, where cell 1 and cell 2 correspond to target SN 1, and cell 3 corresponds to target SN 2.

[0393] When the source SN determines that it needs to trigger CPC configuration between SNs, it sends an SN Change Required message to the MN, which carries the cell information of its recommended alternative cells and / or the execution conditions corresponding to triggering CPC configuration.

[0394] For example, the candidate cells recommended by the source SN for CPC configuration between SNs include: cell 1, cell 2, and cell 5, where cells 1, 2, and 5 correspond to target SN 1. The source SN can carry cell information of cells 1, 2, and 5 and / or the execution conditions corresponding to its CPC configuration to the MN in the SN Change Required message.

[0395] After receiving the SN Change Required message from the source SN, the MN obtains the candidate cells recommended by the source SN and the corresponding candidate target SNs. If the MN discovers that one of the candidate cells provided by the source SN is the same as the second candidate cell in the CPC configuration triggered by the MN for the SN, and / or the target SN where the first candidate cell is located, the MN sends first indication information to the target SN where the first candidate cell is located. The first indication information is used to instruct the target SN to perform CPC configuration selection for the first candidate cell, that is, to instruct the target SN to choose the CPC configuration triggered by the MN and / or the CPC configuration triggered by the SN. The first indication information includes one or more of the following: the PCI of the first candidate cell, the cell frequency information of the first candidate cell, the identifier of the target SN corresponding to the first candidate cell, the CPC execution conditions configured by the MN, and the CPC execution conditions configured by the source SN.

[0396] Based on the above example, if the MN finds that both the second candidate cell and the candidate cells recommended by the source SN are configured with cells 1 and 2 of the target SN, then the MN sends a first indication message to the target SN. This first indication message carries the PCI and / or frequency information of cells 1 and 2, the execution conditions for cells 1 and 2 in the CPC configuration triggered by the MN, and the execution conditions for cells 1 and 2 in the CPC configuration triggered by the source SN.

[0397] The target SN determines the CPC configuration to be triggered by the source SN and / or the CPC configuration to be triggered by the MN for the first candidate cell (e.g., using the CPC configuration triggered by the source SN for the first candidate cell; or using the CPC configuration triggered by the MN for the first candidate cell; or using the CPC configuration triggered by the source SN for some cells in the first candidate cell and the CPC configuration triggered by the MN for others, etc.), and sends a response message to the MN in response to the first indication information. The response message includes one or more of the following: the PCI of the first candidate cell, the cell frequency information of the first candidate cell, the identifier of the target SN corresponding to the first candidate cell, an indication identifier for CPC execution conditions configured using the MN, and an indication identifier for CPC execution conditions configured using the source SN.

[0398] For example, if target SN 1 determines to select source SN to configure CPC for cell 1 and select MN to configure CPC for cell 2, then target SN 1 will carry indication information for CPC configuration triggered by source SN for cell 1 and indication information for CPC configuration triggered by MN for cell 2 in the response message. The indication information for CPC configuration triggered by source SN for cell 1 includes: the PCI and / or frequency information of cell 1, and an indication identifier of the CPC execution conditions configured by source SN for cell 1; the indication information for CPC configuration triggered by MN for cell 2 includes: the PCI and / or frequency information of cell 2, and an indication identifier of the CPC execution conditions configured by MN for cell 2. Of course, as another embodiment, the target SN1 may also determine that the source SN is selected to configure CPC for both cells 1 and 2. In this case, the target SN1 carries indication information in the response message indicating that CPC configuration triggered by the source SN is used for cells 1 and 2. Alternatively, the target SN1 may also determine that the MN is selected to configure CPC for both cells 1 and 2. In this case, the target SN1 carries indication information in the response message indicating that CPC configuration triggered by the MN is used for cells 1 and 2. This embodiment is not limited to these embodiments. When the MN determines, based on the response message from the target SN to the first indication information, that the first candidate cell for CPC configuration triggered by the source SN overlaps with the second candidate cell included in the second cell set, the MN sends a second indication message to the source SN to instruct the source SN to adopt CPC configuration triggered by the MN and / or CPC configuration triggered by the SN for the target cell.

[0399] Taking the example of selecting a source SN to configure CPC for cell 1 and selecting an MN to configure CPC for cell 2, based on the aforementioned target SN 1, the MN sends a second indication message to the source SN, carrying indication information for configuring CPC triggered by the MN for cell 2. This indication information for configuring CPC triggered by the MN for cell 2 includes: the PCI and / or frequency information of cell 2, and an indication identifier for the CPC execution conditions configured by the MN for cell 2. Optionally, it may also carry indication information for configuring CPC triggered by the source SN for cells 1 and 5. This indication information for configuring CPC triggered by the source SN for cells 1 and 5 includes: the PCI and / or frequency information of cells 1 and 5, and an indication identifier for the CPC execution conditions configured by the source SN for cells 1 and 5.

[0400] The source SN sends a response message to the MN in response to the received second indication information. The response message includes: the PCI of the target cell, the cell frequency information of the target cell, the identifier of the target SN corresponding to the target cell, the updated CPC execution conditions corresponding to the target cell, the updated measurement configuration corresponding to the target cell, and an indication identifier for determining the CPC execution conditions configured by the MN.

[0401] For example, based on the aforementioned target SN 1, a source SN is selected to configure CPC for cell 1, and an MN is selected to configure CPC for cell 2. The source SN sends a response message to the MN, including: PCI and / or frequency information for cells 1 and 5; an indication flag confirming the CPC execution conditions configured by the source SN for cells 1 and 5; PCI and / or frequency information for cell 2; confirmation of the source SN for cell 2; and updated measurement configuration and / or execution conditions. Alternatively, the source SN sends a response message to the MN, including at least one of: the SN identifier corresponding to target SN 1; the updated measurement configuration of target SN 1; updated execution conditions; and an indication flag confirming the CPC execution conditions configured by the MN.

[0402] like Figure 2 As shown, this embodiment of the invention also provides a cell processing method applied to a master node MN, the method comprising the following steps:

[0403] Step 21: Send a first message to the source SN. The first message carries third indication information related to each cell in the second cell set. The second cell set includes second candidate cells for CPC configuration between SNs triggered by MN.

[0404] In this embodiment, when the MN triggers CPC configuration between the SNs, the MN may send a first message to the source SN.

[0405] Optionally, the first message may carry one or more indications related to a second candidate cell (i.e., third indications) for indicating the CPC configuration between SNs triggered by the MN, wherein the third indications include at least one of the following:

[0406] PCI of the second candidate cell;

[0407] Cell frequency information of the second candidate cell;

[0408] The identifier (T-SN ID) of the target SN where the second candidate cell is located;

[0409] The CPC execution conditions configured in the MN.

[0410] Accordingly, the source SN receives the first message sent by the master node MN, and determines the candidate cell to trigger CPC configuration between SNs based on the first message. The candidate cell does not overlap with the second candidate cell included in the second cell set.

[0411] The first message carries third indication information related to each cell in the second cell set, and the second cell set includes second candidate cells for the primary serving cell condition change CPC configuration of the secondary cell group between SNs triggered by MN.

[0412] Optionally, based on the first message, a candidate cell for triggering CPC configuration between SNs is determined, and the candidate cell does not overlap with the second candidate cell included in the second cell set. This can be because when the source SN determines the CPC configuration between SNs, it will not select the second candidate cell of the CPC configuration between SNs triggered by the MN indicated in the first message as its candidate cell, and / or it will not configure the target SN where the second candidate cell is located as its candidate target SN. This ensures that when CPC configuration between SNs triggered by the MN and CPC configuration between SNs triggered by the source SN coexist, the CPC candidate cells of CPC configuration between SNs triggered by the MN and CPC configuration between SNs triggered by the source SN are different from each other. This avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing network and air interface burden, and also avoids redundant measurements on the UE side, reducing its power consumption.

[0413] Example 7: During CPC configuration between SNs triggered by MN, the cell information of the candidate cells configured by MN is sent to the source SN.

[0414] Specifically, when CPC configuration between SNs is triggered by MN and MN does not receive a CPC request triggered by source SN, MN sends a first message to source SN to indicate the second candidate cell for CPC configuration between SNs triggered by MN to source SN.

[0415] For example, if the second candidate cells for CPC configuration between SNs triggered by MN are: cell 1, cell 2, and cell 3; where cell 1 and 2 correspond to target SN 1, and cell 3 corresponds to target SN 2, then MN sends a first message to S-SN. The first message includes at least one of the following: the PCI of cells 1, 2, and 3; the cell frequency information of cells 1, 2, and 3; the IDs of target SNs 1 and 2; and indication information indicating that MN has configured CPC.

[0416] The source SN receives a first message sent by the MN, and determines the second candidate cell and / or the target SN where the second candidate cell is located based on at least one of the PCI of the second candidate cell, the cell frequency information of the second candidate cell, and the identifier of the target SN where the second candidate cell is located in the first message, for the CPC configuration between SNs triggered by the MN.

[0417] Optionally, when the source SN triggers CPC configuration between SNs, the second candidate cell for CPC configuration between SNs triggered by the MN determined above is not configured as a backup cell, and / or the target SN where the second candidate cell is located is not configured as a backup target SN.

[0418] Based on the above example, if the source SN receives the first message and determines that the CPC between SNs triggered by the MN has configured cells 1 and 2 of target SN 1 and cell 3 of target SN 2 as second candidate cells, then when the source SN determines the CPC configuration between the triggering SNs, it can perform the following operations: When configuring alternative target SNs or alternative cells, the source SN will exclude the aforementioned target SN 1 and target SN 2 as its alternative target SNs; or the S-SN will still configure target SN 1 as its alternative target SN, but will not select cells 1 and 2 of SN 1 as its alternative cells. This ensures that the CPC candidate cells configured between SNs triggered by the MN are different from the CPC candidate cells configured between SNs triggered by the source SN, and can also effectively avoid the target SN from repeatedly configuring the overlapping cells 1 and 2, thereby reducing network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption.

[0419] Of course, as another embodiment, when configuring alternative target SNs or alternative cells, the source SN can exclude some overlapping cells. For example, the S-SN may still configure target SN1 as its alternative target SN, but will not select cell 1 or cell 2 of SN1 as its alternative cell. In this way, the S-SN can exclude some overlapping cells from the second candidate cells provided by the MN as its alternative cells, so as to avoid the target SN from repeatedly configuring the overlapping cells, thereby reducing the network and air interface burden, and avoiding redundant measurements on the UE side, thus reducing its power consumption. Of course, it should also be noted that the scheme involving excluding the target SN containing overlapping cells in the above embodiments of this application can also exclude all or some target SNs containing overlapping cells, similar to the above embodiments. To avoid repetition, it will not be described again here.

[0420] Optionally, the MN sends the first message to the source SN, which can also be sent when the MN triggers CPC configuration between SNs and has not received the first cell set sent by the source SN. Specifically, embodiments of the present invention also provide a cell processing method, including:

[0421] When CPC configuration between MN and SN is triggered, and the first cell set is not received from the source SN, the first message is sent to the source SN.

[0422] When the MN receives the first cell set sent by the source auxiliary node SN, it determines whether the cells in the first cell set overlap with the cells in the second cell set based on the cell information of the candidate cells included in the first cell set, and processes each cell in the first cell set and the second cell set according to the determination result.

[0423] The first cell set includes cell information of candidate cells, which are cells configured by CPC (Current Service Cell Condition Change) of the secondary cell group between SNs triggered by the source SN; the second cell set includes second candidate cells configured by CPC between SNs triggered by the MN.

[0424] For specific implementations, please refer to Embodiments 1 to 7 above. To avoid repetition, they will not be described again here. This scheme can ensure that when CPCs configured between SNs triggered by MN and CPCs configured between SNs triggered by the source SN coexist, the CPC candidate cells configured between SNs triggered by MN and CPCs configured between SNs triggered by the source SN are different. This avoids configuring multiple sets of CPC configurations for the same candidate cell on the network side, thereby reducing the network and air interface burden. It can also avoid the UE side performing redundant measurements, reducing its power consumption.

[0425] The network device involved in this application embodiment can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, a base station may also be called an access point, or a device in an access network that communicates with a wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface.
