Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, terminal and network equipment for processing conditional cell changes. Background Art

[0002] In the prior art, the New Radio (NR) mobile project supports conditional cell change (Conditional Handover, CHO) + candidate (candidate) secondary cell group (Secondary Cell Group, SCG), and CHO (CHO-only) / CHO + target SCG simultaneous configuration. In this scenario, the terminal may succeed or fail in executing the cell change. If one of the conditional cell changes is executed successfully, it may be due to the failure to meet the execution conditions of another conditional cell change, indicating that the execution conditions configured by the target master node (Master node, MN) are not suitable and the configuration needs to be optimized. If the conditional cell change fails, in order to avoid failure, the relevant configuration also needs to be optimized. Summary of the invention

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

[0511] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone.

[0513] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0514] When describing the embodiments of the present application, some concepts used in the following description are first explained.

[0515] 1. Conditional PCell Change Only (CHO-only)

[0516] The Radio Resource Control (RRC) reconfiguration message in the CHO configuration only includes the configuration information of the Master Cell Group (MCG) and does not carry the configuration information of the SCG.

[0517] 2. One conditional PCell change and one target PSCell change (CHO+target SCG)

[0518] When configuring the CHO configuration, a SCG configuration can be bound to each CHO candidate cell, and this SCG configuration includes the synchronous reconfiguration command on the SCG side. When the user equipment (UE) evaluates that a CHO candidate cell meets the execution conditions, the UE will execute the handover command to switch to the target PCell, and the UE will apply the configured SCG configuration to access a target PSCell.

[0519] 3. One-condition PCell change and multiple-condition PSCell change (CHO+candidate SCG)

[0520] When configuring the CHO configuration, multiple candidate PSCell configurations can be configured for each candidate PCell. In the case where a candidate PCell configuration is associated with multiple candidate PSCell configurations, the network device can provide multiple CHO configurations for this candidate PCell, and each CHO configuration corresponds to a different candidate SCG configuration. The network device reconfigures the execution conditions of the associated PCell and the execution conditions of the associated PSCell for each condition. Only when the PCell and PSCell execution conditions are met at the same time, the UE executes the CHO+candidate SCG configuration and accesses the candidate target PCell and candidate target PSCell. Otherwise, the UE does not execute CHO+candidate SCG and continues to evaluate.

[0521] The embodiments of the present application provide a method, apparatus, terminal and network device for processing conditional cell changes, so as to solve the problem of inappropriate configuration of conditional cell changes.

[0522] Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0523] like Figure 1 As shown, an embodiment of the present application provides a method for processing a conditional cell change, which is applied to a terminal and specifically includes the following steps:

[0524] Step 101: A terminal receives configuration information of a first conditional cell change and configuration information of a second conditional cell change sent by a network device;

[0525] The configuration information of the first conditional cell change includes: configuration information of a primary cell PCell change of a conditional primary cell group and a primary cell PSCell change of multiple conditional secondary cell groups;

[0526] The configuration information of the second conditional cell change includes: configuration information of only conditional PCell change, or configuration information of one conditional PCell change and one target PSCell change.

[0527] Step 102: If the terminal executes the first condition cell change and / or executes the second condition cell change, record cell change related information;

[0528] Step 103: The terminal sends the cell change related information to the network device.

[0529] In this embodiment, the configuration information of the first conditional cell change is the configuration information of CHO+candidate SCG; the configuration information of the second conditional cell change is the configuration information of CHO-only / CHO+target SCG. Executing the first conditional cell change refers to executing the cell change based on the configuration information of the first conditional cell change configured by the network device; executing the second conditional cell change refers to executing the cell change based on the configuration information of the second conditional cell change configured by the network device.

[0530] When the terminal is configured with both CHO+candidate SCG and CHO-only / CHO+target SCG, if the terminal executes CHO+candidate SCG and / or CHO-only / CHO+target SCG, the terminal records the relevant information of the conditional cell change and reports the relevant information of the conditional cell change to the network device, and the network device can send the relevant information of the conditional cell change to other nodes, such as the source MN node accessed by the terminal, and the source MN node can also send the relevant information of the conditional cell change to the target MN node through an interface message. The source MN node and / or the target MN node can optimize the configuration of the conditional cell change based on the relevant information of the conditional cell change.

[0531] It should be noted that the first conditional cell change and the second conditional cell change can be configured to the UE by the network device in one signaling, or in different signaling, and there is no time sequence between the two configuration information.

[0532] It should be noted that there may also be a situation where CHO+candidate SCG, CHO-only and CHO+target SCG are configured at the same time.

[0533] In an embodiment of the present application, when the terminal is configured with the configuration information of the first conditional cell change and the configuration information of the second conditional cell change, if the first conditional cell change and / or the second conditional cell change is performed, the cell change-related information is conditionally recorded and the conditional cell change-related information is sent to the network device, and the network device can obtain the relevant information when the terminal performs the conditional cell change.

[0534] Optionally, the network device may perform configuration optimization of the cell change based on the conditional cell change related information when the terminal executes the conditional cell change, so that the optimized configuration information can meet the cell change requirements.

[0535] As an optional embodiment, if the terminal performs the first conditional cell change and / or performs the second conditional cell change, recording the conditional cell change related information includes at least one of the following:

[0536] If the second conditional cell change is successfully executed, recording relevant information about the successful conditional cell change;

[0537] If the first conditional cell change and / or the second conditional cell change fails to be executed, relevant information about the conditional cell change failure is recorded.

[0538] In this embodiment, the conditional cell change related information includes conditional cell change success related information and / or conditional cell change failure related information. For example: if the terminal executes the first conditional cell change or the second conditional cell change, and the execution is successful, then the conditional cell change success related information is recorded; if the terminal executes the first conditional cell change or the second conditional cell change, and the execution fails, then the conditional cell change failure related information is recorded.

[0539] For the second conditional cell change, i.e. CHO-only / CHO+target SCG, when CHO-only / CHO+targetSCG is executed successfully, it may be because the execution conditions of the candidate PSCell of CHO+candidate SCG configured by the target MN node are not suitable, resulting in the terminal not selecting a candidate PSCell for access or selecting a suitable candidate PSCell for access, but accessing the target PSCell. Therefore, the execution condition configuration of the candidate PCell and / or candidate PSCell of CHO+candidate SCG needs to be optimized. The terminal can record the relevant information of the successful cell change when the CHO-only / CHO+target SCG is executed successfully, and send the relevant information of the successful conditional cell change to the network device, and the network device will optimize the configuration of CHO+candidateSCG.

[0540] If the first conditional cell change and / or the second conditional cell change fails, the terminal records relevant information about the conditional cell change failure, and can report the relevant information about the conditional cell change failure to the network device. The network device can optimize the cell change configuration based on the relevant information about the conditional cell change failure.

[0541] Optionally, the failure of executing the first condition cell change and / or the second condition cell change includes at least one of the following:

[0542] The first condition is that the cell change execution fails; for example, the CHO+candidate SCG execution fails;

[0543] The second condition is that the cell change execution fails; for example, CHO-only execution fails, CHO+target SCG execution fails;

[0544] RLF occurs;

[0545] The legacy HO failed.

[0546] The cell change is successful, and RLF occurs within a second time of accessing the target cell; the second time is a shorter time, that is, the cell change is successful, but RLF occurs within a short time of the target cell.

[0547] Recovery is successful, and RLF occurs within a third time of accessing the recovery cell, where the third time is a shorter time, that is, recovery is successful, but RLF occurs within a short time of accessing the recovery cell.

[0548] In this embodiment, "first condition cell change execution" refers to the cell change executed based on the configuration information of the first condition cell change configured by the network device; "second condition cell change execution" refers to the cell change executed based on the configuration information of the second condition cell change configured by the network device.

[0549] Optionally, the method further includes: receiving first configuration information sent by the network device, the first configuration information being used to instruct the terminal to record information related to a successful conditional cell change.

[0550] In this embodiment, the network device may send first configuration information to the terminal, and the terminal evaluates whether it is necessary to record information related to successful conditional cell change according to an instruction of the first configuration information.

[0554] (2) Second indication information, used to indicate that when the execution condition threshold of the candidate PCell corresponding to the second conditional cell change is less than the execution condition threshold of the candidate PCell corresponding to the first conditional cell change, information related to the success of the conditional cell change should be recorded.

[0555] The network device configures second indication information for the terminal, which is used to indicate that when the execution condition threshold of the candidate PCell of the CHO-only / CHO+target SCG is lower than the execution condition threshold of the candidate PCell of the CHO+candidate SCG, the UE records the success related information and reports it to the network device.

[0556] (3) Third indication information, used to indicate that when the execution condition threshold of the candidate PCell corresponding to the second conditional cell change is less than the execution condition threshold of the candidate PCell corresponding to the first conditional cell change, and the second conditional cell change is successfully executed, information related to the successful conditional cell change is recorded.

[0557] The network device configures the third indication information to the terminal, which is used to indicate that when the execution condition threshold of the candidate PCell of the CHO-only / CHO+target SCG is lower than the execution condition threshold of the candidate PCell of the CHO+candidate SCG, and the CHO-only / CHO+target SCG is executed successfully, the UE records the relevant information of the successful conditional cell change and reports it to the network device.

[0558] In the case where the network device is configured with the above-mentioned first configuration information, the terminal can record the information related to the successful conditional cell change according to the instruction of the first configuration information and report the information to the network device.

[0699] The following example illustrates a situation where a terminal records information related to a successful conditional cell change.

[0700] As an optional embodiment, the network device configures the terminal with the configuration information of CHO-only and CHO+candidate SCG, and CHO-only is successfully executed. The steps are as follows:

[0701] Step 21: The network device configures the following configuration information for the UE:

[0702] (1) CHO-only configuration information, which includes PCell execution conditions and RRCReconfiguration information;

[0703] (2) CHO+candidate SCG configuration information, which includes PCell execution conditions and PSCell execution conditions, and RRC Reconfiguration information, which includes MCG configuration information and SCG configuration information;

[0704] (3) (Optional) an indication message indicating that when the UE is configured with both CHO+candidate SCG and CHO-only and CHO-only is executed successfully, the UE records the information related to the successful conditional cell change and reports it to the network device;

[0705] (4) (Optional) An indication message indicating that when the PCell execution condition threshold of the CHO-only is lower than the PCell execution condition threshold of the CHO+candidate SCG, the UE records the relevant information of the successful conditional cell change and reports it to the network device.

[0706] (5) (Optional) An indication message indicating that when the PCell execution condition threshold of CHO-only is lower than the PCell execution condition threshold of CHO+candidate SCG and CHO-only is successfully executed, the UE shall record the success-related information and report it to the network device.

[0707] Step 22: The UE evaluates the execution conditions. For CHO+candidate SCG, if the execution conditions of the candidate PCell are met, but the execution conditions of the PSCell are not met, then if the CHO-only execution conditions are met, the UE executes CHO-only successfully.

[0708] Step 23: (Optional) Based on the configuration information, the UE records one or more of the following information:

[0709] (1) Information related to candidate cells: mainly information related to candidate cells, such as information related to candidate PCells, information related to candidate PSCells, information related to candidate PSCells, and information related to candidate PSCells.

[0710] (2) Execution condition related information: mainly execution condition related information, such as execution condition information of candidate PCell and execution condition information of candidate PSCell.

[0713] The candidate cell related information specifically includes one or more of the following information:

[0714] a) Identification information and / or measurement result information of each candidate PCell of CHO+candidate SCG;

[0715] b) identification information and / or measurement result information of each candidate PSCell of CHO+candidate SCG;

[0717] d) PSCell identification information and / or measurement result information corresponding to each candidate PCell of CHO+target SCG;

[0718] It should be noted that the identification information may be recorded in the form of a cell global identifier (Cell Global Identifier, CGI) or a frequency point + physical cell identifier (Physical Cell Identifier, PCI), and the measurement result information may include both cell-level measurement results and beam-level measurement results.

[0719] The execution conditions related information includes the following:

[0720] 1) PCell execution conditions of CHO+candidate SCG (such as configured A3 / A5 threshold);

[0721] 2) PSCell execution conditions of CHO+candidate SCG (such as configured A3 / A4 / A5 thresholds);

[0722] 3) CHO-only execution conditions; (such as configured A3 / A5 thresholds).

[0723] 4) The execution condition satisfaction of each candidate cell (i.e., whether the execution condition is satisfied);

[0724] 5) If a candidate cell is configured with two execution conditions, record the first execution condition that is met;

[0725] 6) The specific process of the PCell and PSCell execution conditions of the CHO+candidate SCG being met, for example: during the T1-T2 period, the PCell execution conditions are met, but the PSCell execution conditions are not met; at the T3-T4 time point, the PCell execution conditions are not met, but the PSCell execution conditions are met.

[0726] Specifically, the recorded information may be T1, T2 time, candidate PCell / PSCell identification information, and indication information of whether the execution condition is met; the T1, T2 time may be an absolute time or a relative time, for example: relative to the time of receiving the CHO+candidate SCG configuration, the recorded information may be, for example, that the execution condition of PCell 1 is not met from T1 to T2, but is met from T2 to T3, and the corresponding PSCell 1 does not meet the execution condition from T1 to T4, but is met from T4 to T5, where T4>T2, T3>T4, T5>T3.

[0727] According to the recorded information, the network device can analyze that from T1 to T2, neither the PCell nor the PSCell execution conditions are met, from T2 to T4, the PSCell execution condition is met, and the PSCell execution condition is not met, and from T4 to T3, both the PCell and PSCell execution conditions are met.

[0728] The time-related information includes the following:

[0729] 1) If a candidate cell is configured with two execution conditions, the time difference between the two execution conditions being met is recorded;

[0730] 2) The time difference between the time when the PCell execution condition of the CHO+candidate SCG is satisfied and the time when the execution condition of the CHO-only SCG is satisfied, or vice versa;

[0735] 7) The time difference from receiving the CHO+candidate SCG configuration information to the time when the PCell / PSCell execution conditions of the CHO+candidate SCG are met;

[0736] 8) The time difference from the receipt of the CHO-only configuration information to the moment when the PCell / PSCell execution conditions of the CHO+candidate SCG are met.

[0737] In addition, the terminal may also record other relevant information such as one or more of the following:

[0738] 1) Whether the PCell configured as CHO-only is also configured as the corresponding PCell of CHO+candidate SCG can be indicated explicitly or implicitly. Alternatively, whether the PCell configured as CHO+candidate SCG is also configured as the corresponding PCell of CHO-only can be indicated explicitly or implicitly.

[0739] 2) Reason value; may include one or more of the following:

[0740] 3) The UE is configured with both CHO+candidate SCG and CHO-only, and CHO-only is executed successfully;

[0741] 4) The PCell execution condition threshold of CHO-only is lower than the PCell execution condition threshold of CHO+candidate SCG, and / or CHO-only is executed successfully;

[0742] 5) Location information;

[0743] 6) an indication information indicating the type of the execution condition / candidate cell (configuration) (which can be indicated in an explicit or implicit manner), such as CHO-only, CHO+candidate SCG;

[0744] 7) an indication information indicating the type information executed by the UE, such as: CHO-only, CHO+candidate SCG, CHO+target SCG;

[0745] 8) an indication information indicating the candidate cell type (which can be indicated in an explicit or implicit manner), such as candidate PCell and candidate PSCell;

[0746] 9) Source cell / target cell identification information and measurement information;

[0747] 10) Information of the PSCell for executing the cell change, such as identification information of the PSCell;

[0748] 11) Source PSCell identification information / measurement information;

[0749] It should be noted that: the UE records the above information in the SHR, or records the above information in a new report, or records the above information in other existing reports (such as RLF report, RACH report, etc.).

[0750] Step 24: The UE reports the available indication information to the network device, notifying the network device that the UE side now stores the relevant information of the successful cell change under this condition;

[0751] Step 25: After receiving the obtainable indication information sent by the UE, if the network device wants to obtain the information related to the successful change of the conditional cell, the network device sends a UE information request message to the UE, requesting the UE to send the information related to the successful change of the conditional cell to the network device;

[0752] Step 26: After receiving the UE information request message sent by the network device, the UE sends a UE information response message to the network device, and sends the relevant information of the successful conditional cell change to the network device in the response message;

[0753] Step 27: After receiving the information related to the successful conditional cell change sent by the UE, the network device sends it to the relevant node for analysis and optimization.

[0754] As another optional embodiment, the network device configures the terminal with configuration information of CHO+target SCG and CHO+candidate SCG, and CHO+target SCG is successfully executed. The method includes:

[0755] Step 31: The network device configures the following configuration information for the UE:

[0756] (1) CHO+target SCG configuration information, which includes PCell execution conditions and RRC Reconfiguration information. The RRC Reconfiguration information includes MCG configuration information and SCG configuration information;

[0757] (2) CHO+candidate SCG configuration, where the configuration information includes PCell execution conditions and PSCell execution conditions, and RRC Reconfiguration information, where the RRC Reconfiguration information includes MCG configuration information and SCG configuration information;

[0758] (3) (Optional) an indication message indicating that when the UE configures both CHO+candidate SCG and CHO-only and CHO-only is successfully executed, the UE shall record the relevant information of the successful conditional cell change and report it to the network device;

[0759] (4) (Optional) An indication message indicating that when the PCell execution condition threshold of CHO-only is lower than the threshold of CHO+candidate SCG, and / or CHO-only is executed successfully, the UE shall record the relevant information of the successful conditional cell change and report it to the network device.

[0760] Step 32: The UE evaluates the execution conditions. For CHO+candidate SCG, the PCell execution conditions are met, but the PSCell execution conditions are not met. When the CHO+target SCG execution conditions are met, the UE executes CHO+targetSCG successfully.

[0761] Step 33: (Optional) Based on the configuration information, the UE records the cell change related information. The specific recorded information is not described here.

[0762] Step 34: The UE reports the available indication information to the network device, notifying the network device that the UE side now stores the relevant information of the successful cell change under this condition;

[0763] Step 35: After receiving the obtainable indication information sent by the UE, if the network device wants to obtain the information related to the successful change of the conditional cell, the network device sends a UE information request message to the UE, requesting the UE to send the information related to the successful change of the conditional cell to the network device;

[0764] Step 36: After receiving the UE information request message sent by the network device, the UE sends a UE information response message to the network device, and sends the relevant information of the successful conditional cell change to the network device in the response message;

[0765] Step 37: After receiving the information related to the successful conditional cell change sent by the UE, the network device sends it to the relevant node for analysis and optimization.

[0766] When the network device receives the information related to the successful conditional cell change sent by the UE, the network device sends the information to the relevant nodes for analysis and optimization. Specifically, the network device sends the information related to the successful conditional cell change to the source node (source MN node) through interface signaling, and the source node (source MN node) can send the received information related to the success to the target node (target MN node) through interface signaling, and the source node (source MN node) and / or the target node (target MN node) perform CHO-only / CHO+target SCG and / or CHO+candidate SCG configuration optimization. The interface signaling here can be Xn, X2, F1, E1 interface signaling.

[0767] In this embodiment, when CHO+candidate SCG and CHO-only / CHO+target SCG are configured at the same time, if the CHO-only / CHO+target SCG is executed successfully, the UE will record the relevant information of the successful conditional cell change and report it to the network side, which is used by the network side to optimize the CHO-only / CHO+target SCG and / or CHO+candidate SCG configuration, so that the UE can access a suitable SCG at the same time when executing the PCell change.

[0768] The following example illustrates a situation where a terminal records information related to a failed conditional cell change.

[0769] As an optional embodiment, when CHO+candidate SCG and CHO-only / CHO+target SCG are configured at the same time, if a failure occurs, the UE will record the information related to the conditional cell change failure and report it to the network device.

[0865] 10) Source PSCell identification information / measurement information.

[0866] It should be noted that the above cell identification information may be recorded in the form of CGI or frequency point + PCI, and the measurement result information may include both cell-level measurement results and beam-level measurement results;

[0867] The UE records the above failure information in the RLF report, or records the above failure information in a new report, or records the above failure information in other existing reports (such as CEF report, RACH report, etc.).

[0868] Step 43: The UE reports the available indication information to the network device, notifying the network device that the UE side now stores the information related to the conditional cell change failure.

[0869] Step 44: After receiving the obtainable indication information sent by the UE, if the network device wants to obtain the information related to the conditional cell change failure, it sends a UE information request message to the UE, requesting the UE to send the information related to the conditional cell change failure to the network device.

[0870] Step 45: After receiving the UE information request message sent by the network device, the UE sends a UE information response message to the network device, and the response message carries the relevant information of the conditional cell change failure.

[0871] Step 46: After receiving the information related to the conditional cell change failure sent by the UE, the network device sends it to the relevant node for analysis and configuration optimization.

[0872] As another optional embodiment, the network device is configured with CHO+target SCG and CHO+candidate SCG configurations.

[0873] Step 51: The network device configures the following configuration information for the UE:

[0874] (1) CHO+target SCG configuration information, which includes PCell execution conditions and RRC Reconfiguration information. The RRC Reconfiguration information includes MCG configuration information and SCG configuration information;

[0875] (2) CHO+candidate SCG configuration, the configuration information includes PCell execution conditions and PSCell execution conditions, and RRC Reconfiguration information, the RRC Reconfiguration information includes MCG configuration information and SCG configuration information.

[0876] Step 52: When one or more failure situations in the above embodiments occur to the UE, the UE records information related to the conditional cell change failure.

[0877] The specific content of the information related to the conditional cell change failure recorded by the UE is not repeated here.

[0878] Step 53: The UE reports the available indication information to the network device, notifying the network device that the UE side now stores the information related to the conditional cell change failure.

[0879] Step 64: After receiving the obtainable indication information sent by the UE, if the network device wants to obtain the information related to the conditional cell change failure, it sends a UE information request message to the UE, requesting the UE to send the information related to the conditional cell change failure to the network device.

[0880] Step 65: After receiving the UE information request message sent by the network device, the UE sends a UE information response message to the network device, and the response message carries the relevant information of the conditional cell change failure.

[0881] Step 66: After receiving the information related to the conditional cell change failure sent by the UE, the network device sends it to the relevant node for analysis and configuration optimization.

[0882] When the network device receives the information related to the conditional cell change failure sent by the UE, the network device sends the information to the relevant nodes for analysis and configuration optimization. Specifically, the network device sends the information related to the conditional cell change failure to the source node (source MN node) through interface signaling. The source node (source MN node) can send the received information related to the conditional cell change failure to the target node (target MN node) through interface signaling. The source node (source MN node) can also send the received information related to the conditional cell change failure to the target node (target SN node) through an interface message. The source node (source MN node) and / or the target node (target MN / SN node) performs CHO-only / CHO+target SCG and / or CHO+candidateSCG configuration optimization. The interface signaling here can be Xn, X2, F1, E1 interface signaling.

[0883] In this embodiment, when CHO+candidate SCG and CHO-only / CHO+target SCG are configured at the same time and a failure occurs, the UE will record information related to the conditional cell change failure and report it to the network side, so that the network side can optimize the CHO-only / CHO+target SCG and / or CHO+candidate SCG configuration to effectively avoid the occurrence of failure.

[0884] In an embodiment of the present application, when the terminal is configured with the configuration information of the first conditional cell change and the configuration information of the second conditional cell change, if the first conditional cell change and / or the second conditional cell change are executed, the cell change related information is recorded and the cell change related information is sent to the network device, and the network device can obtain the relevant information when the terminal executes the conditional cell change. The network device can optimize the configuration of the cell change based on the cell change related information when the terminal executes the conditional cell change, so that the optimized configuration information can meet the cell change requirements.

[0885] like Figure 2 As shown, the embodiment of the present application also provides a method for processing conditional cell change, which is applied to a network device, including:

[0886] Step 201: The network device sends configuration information of a first conditional cell change and configuration information of a second conditional cell change to a terminal;

[0887] Step 202: The network device receives conditional cell change related information sent by the terminal, where the conditional cell change related information is related information of the terminal executing the first conditional cell change and / or the terminal executing the second conditional cell change;

[0888] The configuration information of the first conditional cell change includes: configuration information of one conditional PCell change and multiple conditional PSCell changes;

[0889] The configuration information of the second conditional cell change includes: configuration information of only conditional PCell change, or configuration information of one conditional PCell change and one target PSCell change.

[0890] In this embodiment, the configuration information of the first conditional cell change is the configuration information of CHO+candidate SCG; the configuration information of the second conditional cell change is the configuration information of CHO-only / CHO+target SCG. When the network device configures CHO+candidate SCG and CHO-only / CHO+target SCG for the terminal at the same time, if the terminal executes CHO+candidateSCG and / or CHO-only / CHO+target SCG, the terminal records the relevant information of the conditional cell change and reports the relevant information of the conditional cell change to the network device. The network device can send the relevant information of the conditional cell change to other nodes, such as the source MN node accessed by the terminal. The source MN node can also send the relevant information of the conditional cell change to the target MN node through an interface message. The source MN node and / or the target MN node can optimize the configuration of the cell change based on the relevant information of the conditional cell change.

[0891] It should be noted that the network device can configure the first conditional cell change and the second conditional cell change to the UE in one signaling, or can configure them to the UE in different signaling, and the two configuration information have no time sequence.

[0892] It should be noted that there may also be a situation where CHO+candidate SCG, CHO-only and CHO+target SCG are configured at the same time.

[0893] In an embodiment of the present application, when the network device configures the terminal with the configuration information of the first conditional cell change and the configuration information of the second conditional cell change, if the terminal executes the first conditional cell change and / or executes the second conditional cell change, the conditional cell change-related information is recorded and the conditional cell change-related information is sent to the network device. Then, the network device can obtain the relevant information when the terminal executes the conditional cell change.

[0894] Optionally, the network device may optimize the configuration of the cell change according to the acquired conditional cell change related information, so that the optimized configuration information can meet the cell change requirements.

[0895] Optionally, the cell change related information includes at least one of the following:

[0896] (1) information related to a successful conditional cell change when the second conditional cell change is successfully executed;

[0897] (2) Information related to a conditional cell change failure when the first conditional cell change and / or the second conditional cell change fails to be executed.

[0898] In this embodiment, the conditional cell change related information includes conditional cell change success related information and / or conditional cell change failure related information. For example: if the terminal executes the first conditional cell change or the second conditional cell change and the execution is successful, then the conditional cell change success related information is recorded; if the terminal executes the first conditional cell change or the second conditional cell change and the execution fails, then the conditional cell change failure related information is recorded.

[0899] For the second conditional cell change, i.e. CHO-only / CHO+target SCG, when CHO-only / CHO+targetSCG is executed successfully, it may be because the execution conditions of the candidate PSCell of CHO+candidate SCG configured by the target MN node are not suitable, resulting in the terminal not selecting a candidate PSCell for access or selecting a suitable candidate PSCell for access, but accessing the target PSCell. Therefore, the execution condition configuration of the candidate PCell and / or candidate PSCell of CHO+candidate SCG needs to be optimized. The terminal can record the relevant information of the successful cell change when the CHO-only / CHO+target SCG is executed successfully, and send the relevant information of the successful conditional cell change to the network device, and the network device will optimize the configuration of CHO+candidateSCG.

[0900] If the first conditional cell change and / or the second conditional cell change fails, the terminal records relevant information about the cell change failure and can report relevant information about the conditional cell change failure to the network device. The network device can optimize the configuration of the cell change based on the relevant information about the conditional cell change failure.

[0901] Optionally, the failure of executing the first condition cell change and / or the second condition cell change includes at least one of the following:

[0902] The first condition is that the cell change execution fails; for example, the CHO+candidate SCG execution fails;

[0903] The second condition is that the cell change execution fails; for example, CHO-only execution fails, CHO+target SCG execution fails;

[0904] RLF occurs;

[0905] The legacy HO failed.

[0906] The cell change is successful, and RLF occurs within a second time of accessing the target cell; the second time is a shorter time, that is, the cell change is successful, but RLF occurs within a short time of the target cell.

[0907] Recovery is successful, and RLF occurs within a third time of accessing the recovery cell, where the third time is a shorter time, that is, recovery is successful, but RLF occurs within a short time of accessing the recovery cell.

[0908] Optionally, the method further includes:

[0909] Sending first configuration information to the terminal, where the first configuration information is used to instruct the terminal to record information related to a successful conditional cell change;

[0910] The first configuration information includes at least one of the following:

[0911] The first indication information is used to indicate that when the terminal is configured with the configuration information of the first conditional cell change and the configuration information of the second conditional cell change, if the second conditional cell change is successfully executed, then the relevant information of the successful conditional cell change is recorded;

[0912] The second indication information is used to indicate that when the execution condition threshold of the candidate PCell corresponding to the second conditional cell change is less than the execution condition threshold of the candidate PCell corresponding to the first conditional cell change, relevant information on the successful conditional cell change is recorded;

[0913] The third indication information is used to indicate that when the execution condition threshold of the candidate PCell corresponding to the second conditional cell change is less than the execution condition threshold of the candidate PCell corresponding to the first conditional cell change, and the second conditional cell change is successfully executed, the relevant information of the successful conditional cell change is recorded.

[0914] In this embodiment, the network device may send first configuration information to the terminal, and the terminal evaluates whether it is necessary to record information related to successful conditional cell change according to an instruction of the first configuration information.
