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 this disclosure.

[0211] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0212] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0213] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0214] The embodiments of this disclosure provide a method, apparatus, terminal, and device for recording and reporting mobility reports, in order to solve the problem that mobility information recording methods of related technologies may cause information loss for frequent mobility processes.

[0215] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0216] As shown in Figure 1, an embodiment of this disclosure provides a method for recording and reporting mobility reports, applied to a terminal, specifically including the following steps:

[0217] Step 101: The terminal performs continuous cell change, where the continuous cell change is L1 / L2 triggered Mobility Cell Change (LTM) or Continuous Condition Secondary Cell Group Primary Cell Addition / Change (S-CPAC).

[0218] In this embodiment, the continuous cell change refers to a cell change configured with LTM and / or S-CPAC, where the configuration is not released after the cell change is performed. The continuous cell change can be a cell change with high-frequency mobility, such as LTM and / or S-CPAC, where S-CPAC can also be represented as subsequent CPAC. It should be noted that the continuous cell change can also be other cell changes with high-frequency mobility besides LTM and / or S-CPAC.

[0219] Step 102: The terminal records the success information and / or failure information of the continuous cell changes;

[0220] Step 103: The terminal reports the success information and / or failure information of the continuous cell change to the network-side device.

[0221] The terminal performs continuous cell change and records success and / or failure information of continuous cell change. For example, the terminal performs LTM and records success and / or failure information of LTM; or, the terminal performs S-CPAC and records success and / or failure information of S-CPAC.

[0222] The LTM process performed by the terminal is as follows: The network-side equipment pre-configures multiple candidate cell configurations and their L1 measurement configurations for the terminal. The terminal performs L1 measurements based on the L1 measurement configurations configured by the network-side equipment and reports the results. Based on the L1 measurement results reported by the terminal, the network-side equipment sends an LTM cell switch command to the terminal (User Equipment, UE). This LTM cell switch command can be sent to the UE through the Medium Access Control (MAC) control element (CE). When the UE receives the LTM cell switch command from the network-side equipment, the terminal will execute the LTM cell switch to access the target cell. The UE will maintain the LTM configuration and continue performing L1 measurements, continuing the subsequent LTM process.

[0223] The process of a terminal executing S-CPAC is as follows: The network-side equipment pre-configures multiple candidate primary and secondary cells (PSCells) for the UE and configures corresponding execution conditions for each candidate PSCell. When the terminal receives the CPAC configuration information, it begins to evaluate the CPAC execution conditions. If the execution conditions are met, the terminal performs a PSCell change to access the candidate target PSCell that meets the execution conditions. After successfully performing the PSCell change and accessing the candidate target cell, the terminal maintains the stored S-CPAC configuration information and continues the subsequent CPAC process.

[0224] The failure information for continuous cell changes can be information about radio link failure (RLF), handover failure, or PSCell addition / change failure. For example, for RLF: the terminal receives LTM configuration from the network-side device, and before receiving the LTM cell switch command, the terminal experiences a radio link failure in the source cell; for handover failure, the terminal receives an LTM cell change command (Master Cell Group, MCG side) from the network-side device, instructing the terminal to access cell 1; the terminal executes LTM, and fails to access cell 1, the terminal performs cell selection to determine access to cell 2, the terminal performs LTM recovery and successfully accesses cell 2, and the terminal records an RLF report; for PSCell addition / change, the terminal receives an LTM cell change command (Secondary Cell Group, MCG side) from the network-side device. The SCG (Search Engine Group) instructs the terminal to access cell 3. The terminal performs LTM (Link Transfer Mechanism) but fails to access cell 3, reporting an SCG failure information (Failure Information) message. This RLF report can be used to record information related to radio link failures or handover failures.

[0225] The success information for continuous cell changes can be critical failure information. For example: a terminal receives an LTM cell change command sent by a network-side device, instructing the terminal to access cell 1; the terminal executes LTM and successfully accesses cell 1, but a critical failure occurs, such as T310 exceeding a configured threshold, or T312 exceeding a configured threshold, or T304 exceeding a configured threshold. In this case, the terminal records a Successful Handover Report (SHR) or a Successful PSCell Change or Addition (SPR). This SHR or SPR can be used to record information related to successful cell changes (but with a critical failure).

[0226] In embodiments of this disclosure, the terminal performs continuous cell changes and records success and / or failure information for each continuous cell change, avoiding the overwriting of historical failure / success information by new failure / success information, thus preventing information loss and enabling the terminal to provide more information for network optimization.

[0227] As an optional embodiment, recording the success and / or failure information of the continuous cell changes includes:

[0228] Record successful and / or failed information for consecutive cell changes in the first report list;

[0229] or,

[0230] Successful continuous cell change information is recorded in the second report list, and failed continuous cell change information is recorded in the third report list. The second report list and the third report list are two different report lists.

[0231] In this embodiment, when the terminal has successful and / or failed information regarding continuous cell changes, or when successful and / or failed information regarding continuous cell changes is generated, it can record the success and failure information in the same report list (the first report list). That is, regardless of whether the continuous cell change is executed successfully or fails, the relevant results can be recorded in the first report list. When the terminal reports continuous cell change information to the network-side device, it reports the first report list. Alternatively, when the terminal has successful and / or failed information regarding continuous cell changes, or when successful and / or failed information regarding continuous cell changes is generated, it can record the success and failure information separately in different report lists. For example, the terminal records the successful information regarding continuous cell changes in the second report list and the failed information in the third report list. When the terminal reports continuous cell change information to the network-side device, it reports the second report list and / or the third report list.

[0232] It should be noted that each report in the first report list, the second report list, and / or the third report list can be a new report or a traditional report (e.g., failure information can be recorded in an RLF report, and success information can be recorded in an SHR or SPR report). For example, each report in the first report list, the second report list, and / or the third report list can be a newly introduced report to record success and / or failure information of LTM / S-CPAC, i.e., not based on RLF report / SHR / SCGFailureInformation / SPR report records of related technologies.

[0233] It should be noted that the second report and the third report do not need to be recorded simultaneously; that is, the terminal records the second report and the third report as separate and independent processes.

[0234] It should be noted that the terminal records the success and / or failure information of the continuous cell change in a list format, i.e., the first report list, second report list, and third report list mentioned above, or it can be recorded in a non-list format, in which case the first report list, second report list, and third report list mentioned above can be replaced with first report, second report, and third report. The terminal can record the success and / or failure information of the continuous cell change in the first report, second report, and third report.

[0235] In some embodiments, the method further includes: after each recording of success information and / or failure information of the continuous cell change, the terminal reports obtainable indication information to the network-side device, indicating that the terminal has stored success information and / or failure information of the continuous cell change.

[0236] In some embodiments, each entry in the first report list is used to record one successful or one failed cell change; each entry in the second report list is used to record one successful cell change; and each entry in the third report list is used to record one failed cell change.

[0237] In this embodiment, each entry in the first report list includes one success or failure message. The success or failure message recorded in each entry can be an SHR, SPR, or RLF report. For example, the first entry in the first report list records a continuous cell change success message (SHR), the second entry records a continuous cell change success message (SHR), and the third entry records a continuous cell change failure message (RLF report).

[0238] The second report list is used only to record successful information of continuous cell changes, so each entry includes one success message, which can be an SHR or SPR; the third report list is used only to record failed information of continuous cell changes, so each entry includes one failure message, which can be an RLF report.

[0239] In this embodiment, the recording method for the success and / or failure information of continuous cell changes can be in list form or non-list form. If recorded in list form, each entry in the list is not recorded as a report, but only each success and / or failure information is recorded in each entry of the list. This recording method can be to record success and failure in one list or in different lists. If recorded in non-list form, this report can include multiple success and failure information, or multiple success and multiple failure information can be recorded in different reports.

[0240] As an optional embodiment, recording the success and / or failure information of the continuous cell changes includes:

[0241] If the Mth cell change in the continuous cell change meets the first condition, then the success or failure information of the Mth cell change is recorded independently, or the number of occurrences corresponding to the cell change is recorded; M is any consecutive cell change.

[0242] The first condition includes: at least one change has been performed between the source cell and the target cell in the Mth cell change, and the terminal records success and / or failure information of the change from the source cell to the target cell.

[0243] In some embodiments, when recording the number of occurrences corresponding to the cell change, the number of occurrences can be counted together for both success and failure information, or the number of occurrences can be counted separately for each type of information.

[0244] In this embodiment, for two (or more) handovers / PSCell changes of the same source cell and target cell, the terminal can record the results of several cell changes in different entries, or it can record the results of several cell changes in the same entry and record the number of times. For example, it can record the number of times the cell change from cell 1 to cell 2 failed or the number of times the critical failure occurred.

[0245] For example: Suppose that entry1 in the first report list has recorded the successful information of a cell change between source cell 1 and target cell 2. If the terminal then performs a second cell change between source cell 1 and target cell 2 and the cell change is successful (but a critical failure occurs), then the terminal records the successful information of the second cell change in other entries in the first report list (such as entry5). If the terminal then performs a third cell change between source cell 1 and target cell 2 and the change fails, then the terminal records the failure information of the third cell change in other entries in the first report list (such as entry9).

[0246] Alternatively, taking the counting of success and failure messages separately as an example: If entry1 in the first report list has already recorded a successful cell change between source cell 1 and target cell 2, and the terminal subsequently performs a second successful cell change between source cell 1 and target cell 2 (but a critical failure occurs), then the terminal records 2 times in entry1 for this successful (but critical failure) cell change between source cell 1 and target cell 2. If the terminal subsequently performs a third successful (but critical failure) cell change between source cell 1 and target cell 2, then the terminal records 3 times in entry1 for this successful (but critical failure) cell change between source cell 1 and target cell 2. The recording method for cell change failures is similar to that for successful cell changes, and will not be elaborated here.

[0247] Alternatively, taking the counting of success and failure information together as an example: if the terminal performs two cell changes for source cell 1 and target cell 2, and both changes are successful (but a critical failure occurs), the number of cell changes (including success and / or failure) can be recorded as 2 in entry1 of the first report list; if the terminal subsequently performs a third cell change for source cell 1 and target cell 2, and the change fails, then the terminal records the number of cell changes (including success and / or failure) as 3 in the aforementioned entry1.

[0248] For example: Suppose that entry1 in the second report list has already recorded the successful information of a cell change between source cell 1 and target cell 2. If the terminal subsequently performs a second cell change between source cell 1 and target cell 2 and the change is successful (but a critical failure occurs), then the terminal records the successful information of the second cell change in other entries in the second report list (such as entry5). If the terminal subsequently performs a third cell change between source cell 1 and target cell 2 and the change is successful (but a critical failure occurs), then the terminal needs to record the successful information in the second report list (such as entry 9).

[0249] Alternatively, assuming that entry1 in the second report list has already recorded a successful cell change between source cell 1 and target cell 2, and the terminal subsequently performs a second cell change between source cell 1 and target cell 2, and the change is successful (but a critical failure occurs), then the terminal records 2 times in entry1 of the second report list that the cell change between source cell 1 and target cell 2 was successful (but a critical failure occurred); if the terminal subsequently performs a third cell change between source cell 1 and target cell 2, and the change is successful (but a critical failure occurs), then the terminal needs to record 3 times in entry1 of the second report list that the cell change between source cell 1 and target cell 2 was successful (but a critical failure occurred).

[0250] The recording method for failed community change (third report list) is similar to the recording method for successful community change, and will not be repeated here.

[0276] The fourth time interval is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list;

[0277] The fifth time interval is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list.

[0278] In this embodiment, 1) a first time interval, the first time interval being the time interval between the terminal receiving the configuration information of the continuous cell change and the release of the configuration information; for example: the first time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the release of the configuration.

[0279] 2) Second time interval, which is the time interval between the terminal receiving the configuration information of the continuous cell change and the configuration information being updated; for example, the second time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the configuration being updated.

[0280] 3) The cell identifier of the continuously changing cell configuration information received by the terminal; for example, it could be the cell identifier information of the cell to which the terminal is connected when it receives the latest LTM configuration / S-CPAC configuration. Another example: it could be the cell identifier information of the cell to which the terminal is connected when it first receives the LTM configuration / S-CPAC configuration.

[0281] 4) The cell identifier corresponding to the terminal when the configuration information of the continuous cell change is released; for example, the cell identifier information of the cell connected when releasing the LTM configuration / S-CPAC configuration.

[0282] 5) The cell identifier corresponding to the terminal when the configuration information of the continuous cell change is updated; for example, the cell identifier information of the connected cell when updating the LTM configuration / S-CPAC configuration.

[0283] 6) A third time interval, which is the time interval between the terminal's most recent receipt of configuration information for continuous cell changes and the terminal's submission of a report list; for example, the third time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the submission of the report list for this continuous cell change. The report list can be any one of the first report list, the second report list, and the third report list.

[0284] 7) A fourth time interval, which is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list; for example, the fourth time interval is the time interval between the first failure of the terminal's LTM / S-CPAC execution and the reporting of the continuous cell change report list. The report list can be a first report list or a third report list.

[0285] 8) The fifth time interval is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list.

[0286] For example, this fifth time interval is the time interval between the first successful execution of LTM / S-CPAC and the submission of the continuous cell change report list. The report list can be either the first report list or the second report list.

[0287] As an optional embodiment, the method further includes:

[0288] If the number of reports recorded in the report list reaches the maximum allowed number of reports, and a new report is generated that exceeds the maximum allowed number of reports, the terminal will not record the new report; or, the terminal will delete the report with the earliest recording time in the report list and record the new report in the report list.

[0289] The report list includes at least one of the first report list, the second report list, and the third report list.

[0290] In this embodiment, each report list can be configured with a maximum allowed number of reports to be recorded, i.e., each report list has a maximum allowed number of entries. If a report list has a maximum of N entries, and new reports are still generated after N entries have been recorded, the terminal will either not record new reports or delete the oldest (i.e., the earliest recorded report) and record new reports.

[0291] For example, the first report list allows a maximum of 8 entries. If a new success or failure message is generated after the terminal has recorded 8 success and / or failure messages, the terminal may choose not to record the newly generated success or failure message, or delete the first entry in the first report list and record the newly generated success or failure message.

[0292] As an optional embodiment, recording the success and / or failure information of the continuous cell changes includes:

[0293] The first report records one successful or one failed instance of a continuous cell change.

[0294] The reporting of success and / or failure information of the continuous cell change to the network-side device includes: reporting the first report to the network-side device.

[0295] In this embodiment, each time success and / or failure information for a consecutive cell change is generated, the terminal records the success and / or failure information for that consecutive cell change, and immediately reports the relevant information to the network-side device after recording each success or failure information. For example, if the terminal performs an LTM cell change and the change is successful (but a critical failure occurs), the terminal records the success information for this LTM cell change and reports the success information for this LTM cell change to the network-side device.

[0296] In some embodiments, the terminal can notify the network-side device with an indication message each time a report is generated, which can be either a new indication message or a legacy indication message.

[0297] As an optional embodiment, the reporting of success and / or failure information of the continuous cell changes to the network-side device includes at least one of the following:

[0298] (1) After sending the reconfiguration completion message, report the success information and / or failure information of the continuous cell change to the network-side device;

[0299] In this embodiment, after the terminal performs continuous cell change, it sends a reconfiguration completion message to the network-side device. After sending the reconfiguration completion message, the terminal actively reports the success information and / or failure information of the continuous cell change to the network-side device, such as sending a stored first report list, or a second report list or a third report list to the network-side device. This process can be based on the network-side configuration, that is, based on the first indication information sent by the network-side device in (3) (used to instruct the terminal to report the success information and / or failure information of the continuous cell change if the storage contains the success information and / or failure information of the continuous cell change).

[0300] (2) Send a reconfiguration completion message to the network-side device, wherein the reconfiguration completion message carries success information and / or failure information of the continuous cell change;

[0301] In this embodiment, after the terminal performs consecutive cell changes, it sends a reconfiguration completion message to the network-side device. The reconfiguration completion message may carry recorded success and / or failure information of the consecutive cell changes. For example, the reconfiguration completion message may carry a first report list, a second report list, or a third report list.

[0302] (3) According to the first indication information of the network side device, report the success information and / or failure information of the continuous cell change to the network side device. The first indication information is used to request the terminal to report the success information and / or failure information of the continuous cell change, or the first indication information is used to instruct the terminal to report the success information and / or failure information of the continuous cell change when the success information and / or failure information of the continuous cell change is stored.

[0303] In this embodiment, the terminal can report success and / or failure information of continuous cell changes based on requests or instructions from the network-side device. For example, the network-side device sends a first instruction to the terminal, instructing the terminal to report success and / or failure information of continuous cell changes. Or, for example, the network-side device sends a first instruction to the terminal, instructing the terminal to report success and / or failure information of continuous cell changes immediately when it has stored such information.

[0304] (4) Send a second indication message to the network-side device, the second indication message being used to indicate that the terminal expects to report the success information and / or failure information of the continuous cell change;

[0305] In this embodiment, the terminal can send a second indication message to the network-side device to indicate that the terminal has a tendency to send a report. The UE can send the indication message to the network side to indicate the tendency to report this report. When the network side receives this tendency sent by the terminal, the network side decides whether to request this report. The terminal reports the success information and / or failure information of the continuous cell change according to the request message of the network-side device. The reporting of the second indication message can be based on the configuration of the network-side device, that is, based on the third indication message in (5).

[0306] (5) Receive third indication information sent by the network-side device, the third indication information being used to instruct the terminal whether it expects to send the success information and / or failure information of the continuous cell changes if it has stored the success information and / or failure information of the continuous cell changes. The terminal sends an indication information to the network-side device according to the third indication information, indicating that it expects to report the success information and / or failure information of the continuous cell changes; the network-side device may request the success information and / or failure information of the continuous cell changes from the terminal.

[0307] In this embodiment, the network-side device can send a third indication message to the terminal, instructing the terminal to report a potential report when it stores success and / or failure information for consecutive cell changes. Based on this potential report-sending intention, the network side decides whether to request the report. The terminal then reports the success and / or failure information for the consecutive cell changes according to the request message from the network-side device.

[0308] (6) Network implementation method: When the target cell determines that the terminal has undergone continuous cell change, after the terminal successfully accesses the target cell, the target cell sends a request message to the terminal to request the terminal to report the information of success and / or failure of continuous cell change. The terminal reports the information of success and / or failure of continuous cell change based on the network request (if the terminal has stored such information).

[0309] It should be noted that the success information and / or failure information of continuous cell changes mentioned in (1) to (6) above can refer to a report or report list in which the terminal records the success information and / or failure information of continuous cell changes.

[0310] As an optional embodiment, the method further includes:

[0311] In the event of other mobility activities occurring on the terminal, the success or failure information of the other mobility activities may be recorded independently in the first, second, or third report list; or, the success or failure information of the other mobility activities may be recorded in the fourth report list.

[0312] In this embodiment, other mobility activities include legacy L3 handover (HO), conditional handover (CHO), legacy PSCell addition / change, and CPAC. When other mobility activities occur at the terminal, mobility success or failure information can be recorded in a new report (such as the fourth report list). In some embodiments, the new report can override the old report (an already stored report or report list); or, it can continue to be recorded as a separate entry in the old report (an already stored report or report list).

[0313] As an optional embodiment, the method further includes:

[0314] If the configuration information for continuous cell changes is released, and updated configuration information for continuous cell changes is received, then continuous cell changes are performed according to the updated configuration information for continuous cell changes, and the first operation is performed.

[0315] The first operation includes at least one of the following:

[0316] 1) Record the success and / or failure information of the continuous cell changes in the fifth report list;

[0317] In this embodiment, after releasing the configuration information for continuous cell changes, if a new continuous cell change configuration is received, a new report list (such as the fifth report list) can be generated based on the new configuration. The new report list records the cell change success information and / or failure information corresponding to the new configuration. In some embodiments, the new report list can overwrite the old report list.

[0318] 2) Release the first report list, the second report list, or the third report list;

[0319] In this embodiment, after releasing the configuration information of continuous cell changes, if a new configuration of continuous cell changes is received, the terminal can directly release the report or report list generated based on the old configuration information.

[0320] 3) Send a fourth indication message to the network-side device, the fourth indication message being used to indicate that the terminal expects to report the first report list, the second report list, or the third report list;

[0321] In this embodiment, after releasing the configuration information of continuous cell changes, if a new continuous cell change configuration is received, the terminal can report a fourth indication to the network-side device, indicating that the terminal has a tendency to report the stored report list.

[0322] 4) Send a fifth instruction message to the network-side device, the fifth instruction message being used to instruct the terminal to store the first report list, the second report list, or the third report list.

[0323] In this embodiment, after releasing the configuration information of continuous cell changes, if a new continuous cell change configuration is received, the terminal can report the fifth indication information to the network-side device, indicating that the terminal stores the above-mentioned report list, so that the network side can decide whether to request the report list.

[0324] As an optional embodiment, the method further includes:

[0325] When the configuration information for the continuous cell change is released, a sixth indication message is sent to the network-side device. The sixth indication message is used to instruct the terminal to store the success information and / or failure information of the continuous cell change.

[0326] In this embodiment, after releasing the configuration information for continuous cell changes, the terminal can report a sixth indication to the network-side device, indicating that the terminal stores the success information and / or failure information of the continuous cell changes, so that the network side can decide whether to request the success information and / or failure information of the continuous cell changes. The success information and / or failure information of the continuous cell changes can refer to a report or a report list in which the terminal records the success information and / or failure information of the continuous cell changes.

[0327] The following example illustrates the process of how a terminal records success and / or failure information for continuous cell changes.

[0328] Example 1: Taking the continuous cell change as an example of an LTM / S-CPAC cell change. Success and / or failure information for continuous cell changes is recorded in a report list.

[0329] The report list can be the first report list, which records the success and / or failure reports generated by the terminal from receiving the LTM / S-CPAC configuration to the configuration release / update. The success and / or failure reports can use traditional success and / or failure reports, such as the RLF report / SHR on the Master Cell Group (MCG) side and the SCG Failure Information message / SPR on the Secondary Cell Group (SCG) side.

[0330] Taking the execution of MCG LTM cell change by the terminal as an example, the process of the terminal recording success and / or failure information of consecutive cell changes and reporting it to the network side includes:

[0331] Step 21: The UE receives LTM configuration information. The current UE is in cell 0, and the network-side equipment has configured LTM candidate cells from cell 1 to cell 6 for the UE.

[0332] Step 22: When the UE reports the L1 measurement results to the network-side equipment;

[0333] Based on the reported L1 measurement results, the network-side equipment sends an LTM cell switch command to the UE, instructing the UE to access cell 5.

[0334] When the UE performs LTM access to cell 5, a handover failure occurs. The UE performs cell selection to select cell 2. The UE performs LTM recovery and successfully accesses cell 2. The UE records an RLF report in the first entry of the report list, as shown in Figure 2.

[0335] Step 23: The network-side device sends an LTM cell switch command to the UE based on the L1 measurement results, instructing the UE to access cell 3. The UE executes LTM and successfully accesses cell 3, but a critical failure occurs. The UE records an SHR in the second entry of the report list, as shown in Figure 2.

[0336] Step 24: Before the UE receives the new LTM cell switch command, the UE experiences an RLF in cell 3. The UE selects cell 2 and successfully accesses cell 2 after performing LTM recovery. The UE records the RLF report in the third entry of the new list, as shown in Figure 2.

[0337] Step 25: The network-side device sends an LTM cell switch command to the UE based on the L1 measurement results, instructing the UE to access cell 3. The UE executes LTM and successfully accesses cell 3, but a critical failure occurs. The UE records SHR in the fourth entry of the report list, as shown in Figure 2.

[0338] Step 26: Release LTM configuration on network-side devices;

[0339] Step 27: The UE records other information into the report list; it should be noted that this information can be recorded in any of the steps 21 to 26 above, as shown in Figure 2.

[0340] In some embodiments, for two (or more) handovers / PSCell changes of the same source cell and target cell, the terminal may record the corresponding success or failure information in different entries of the report list (as shown in Figure 2); or, the terminal may record the corresponding success or failure information in the same entry and record the number of times (as shown in Figure 3).

[0341] In some embodiments, the information recorded in the report list (such as RLF report / SHR / SCGFailureInformation message / SPR) may include one or more of the following:

[0342] Source community identification information;

[0343] Target community identification information;

[0344] Failed community identification information;

[0345] Measurement results information for the service cell and neighboring cells;

[0346] Cell Radio Network Temporary Identifier (C-RNTI) information can be either the C-RNTI of the source cell or the C-RNTI of the target cell;

[0347] Rebuild community signage information;

[0348] Reconnect to cell identification information;

[0349] The time interval from connection failure to the UE re-entering the connected state (after reconstruction failure);

[0350] The time interval from connection failure to the submission of this new report;

[0351] The time interval from receiving a mobility command (such as a handover command or PSCell change command) / executing a mobility command (such as performing a handover / performing a PSCell change) to connection failure;

[0352] Connection failure type (e.g., handover failure, wireless link failure);

[0353] Location information;

[0354] Random access related information;

[0355] No suitable neighborhood information was found;

[0356] SHR / SPR cause;

[0357] SCG failure type information (such as T310 timeout, T312 timeout, beam (beam0 failure recovery failure, etc.);

[0358] The first CPAC execution condition to be met;

[0359] The time interval between two CPAC execution conditions being met;

[0360] CPAC candidate cell information (an indicator can be added during neighbor cell measurement to show whether the neighbor cell is a CPAC candidate cell);

[0361] LTM recovers cell identification information;

[0362] LTM candidate cell information; including LTM candidate cell identification information (which can be recorded in a list or an indicator added to the neighbor cell measurement results to indicate whether the neighbor cell is an LTM candidate cell) and L1 measurement result information;

[0363] Switching type indication information (such as LTM);

[0364] The time interval from receiving the LTM configuration to LTM execution;

[0365] The time interval from receiving the S-CPAC configuration to the execution of S-CPAC;

[0366] The time interval from the last LTM execution / LTM failure / LTM log report to the current LTM execution;

[0367] The time interval from the last S-CPAC execution / S-CPAC failure / S-CPAC log report to the current S-CPAC execution;

[0368] The type (success or failure) can be indicated by a message indicating whether this entry record is a success or failure message;

[0369] The time interval from receiving the LTM configuration / S-CPAC configuration to the release or update of the configuration;

[0370] Cell identification information received when LTM configuration / S-CPAC configuration is received; this could be the cell identification information received for the first time when LTM configuration / S-CPAC configuration is received.

[0371] Cell identification information when updating / releasing LTM configuration / S-CPAC configuration;

[0372] The time interval from receiving the latest LTM configuration / S-CPAC configuration to the corresponding report being reported;

[0373] The time interval from the first LTM / S-CPAC execution failure / success to the corresponding report being submitted.

[0374] In some embodiments, the number of entries in the report list is at most N (e.g., N can be 8 or other values). If new reports are still generated after N entries are exceeded, the UE will not record the new reports or will delete the oldest report and record the new reports.

[0375] Step 28: The UE reports an availability indication to the network-side device, indicating that the UE stores a list of such reports. This indication can reuse legacy information or introduce new information. The availability indication sent by the UE can be:

[0376] a: The UE sends an indication of availability after each RLF report / SHR is recorded;

[0377] b: After the LTM / S-CPAC configuration is released, the UE sends an availability indication message.

[0378] Step 29: When the network-side device receives the indication information sent by the UE, the network-side device sends a request message to request the UE to report this report list;

[0379] Step 210: Based on the request message from the network-side device, the UE reports the aforementioned report list;

[0380] Step 211: The network-side device performs LTM / S-CPAC mobility optimization based on the report list.

[0381] It should be noted that in this embodiment, the LTM mentioned above is MCG LTM and / or SCG LTM. Success indicates that although the cell change was successfully executed, a critical failure occurred.

[0382] The above list of reports (such as RLF report / SHR / SCGFailureInformation message / SPR) is only a partial list. It may also include other LTM / S-CPAC related content, which will not be listed exhaustively here.

[0383] Figure 3 above shows that handover / PSCell change SHR records for non-adjacent source cells and target cells are recorded in the same entry. Handover / PSCell change SHR records for adjacent source cells and target cells can also be recorded in the same entry. Similarly, handover / PSCell change SHR records for source cells and target cells and RLF reports can also be recorded in the same entry (adjacent or non-adjacent). Further details are omitted here. Figure 3 uses SHR as an example; RLF reports are similar.

[0384] This embodiment uses the MCG-side RLF report / SHR as an example for illustration, but it is also applicable to the SCG-side SCGFailureInformation / SPR.

[0385] In embodiments of this disclosure, the terminal records success and failure information of continuous cell changes in the same report list and reports it to the network side, enabling the network side to perform network optimization based on the report list.

[0386] Example 2: Taking the continuous cell change as an example of an LTM / S-CPAC cell change, success and failure information for continuous cell changes are recorded in different report lists.

[0387] The report list records success and failure reports generated from receiving the LTM / S-CPAC configuration to the release / update of the configuration. These success and failure reports can use traditional success and failure reports, such as the RLF report / SHR on the MCG side and the SCGFailureInformation message / SPR on the SCG side.

[0388] Taking the execution of MCG LTM cell change by the terminal as an example, the process of the terminal recording success and / or failure information of consecutive cell changes and reporting it to the network side includes:

[0389] Step 31: The UE receives LTM configuration information. The current UE is in cell 0, and the network-side equipment has configured LTM candidate cells from cell 1 to cell 6 for the UE.

[0390] Step 32: When the UE reports the L1 measurement results to the network, the network-side device sends an LTM cell switch command to the UE based on the reported L1 measurement results, instructing the UE to access cell 5. The UE executes LTM, and a handover failure occurs when accessing cell 5. The UE selects cell 2 and successfully accesses cell 2 after executing LTM recovery. The UE records the RLF report in the first entry of the RLF report list, as shown in Figure 4.

[0391] Step 33: The network-side device sends an LTM cell switch command to the UE based on the L1 measurement results, instructing the UE to access cell 3. The UE executes LTM and successfully accesses cell 3, but a critical failure occurs. The UE records the SHR in the first entry of the SHR list, as shown in Figure 5.

[0392] Step 34: Before the UE receives the new LTM cell switch command, the UE experiences an RLF in cell 3. The UE selects cell 2 and successfully accesses cell 2 after performing LTM recovery. The UE records the RLF report in the second entry of the RLF report list, as shown in Figure 4.

[0393] Step 35: The network-side device sends an LTM cell switch command to the UE based on the L1 measurement results, instructing the UE to access cell 3. The UE executes LTM and successfully accesses cell 3, but a critical failure occurs. The UE records the SHR in the second entry of the SHR list, as shown in Figure 5.

[0394] Step 36: Release LTM configuration on network-side devices;

[0395] Step 37: The UE records other information into the RLF report list or SHR list. It should be noted that this information can be recorded during any of steps 31 to 36 above, as shown in Figure 4 or Figure 5.

[0396] In some embodiments, for two (or more) handovers / PSCell changes of the same source cell and target cell, the terminal may record the corresponding success or failure information in different entries of the RLF report list or SHR list (as shown in Figure 4 or Figure 5); or, the terminal may record the corresponding success or failure information in the same entry and record the number of times, as shown in Figure 6.

[0397] The information recorded in the report list (such as RLF report / SHR / SCGFailureInformation message / SPR) is the same as in Example 1, and will not be repeated here.

[0398] In some embodiments, the number of entries in the RLF report list or SHR list is at most N (e.g., N can be 8 or other values). If new reports are still generated after N entries are exceeded, the UE will not record the new reports or will delete the oldest report and record the new reports.

[0399] Step 38: The UE reports availability indication information to the network-side device. The UE reports two different availability indications: one for the RLF report list and one for the SHR list. The UE indicates to the network-side device that it has stored this RLF report list / SHR list. The indication information can reuse legacy indication information or introduce new indication information. The availability indication information sent by the UE can be:

[0400] The UE sends an available indication message after each RLF report / SHR is recorded;

[0401] After the LTM / S-CPAC configuration is released, the UE sends an availability indication message.

[0402] Step 39: When the network-side device receives the indication information sent by the UE, the network-side device sends a request information to request the UE to report this report list;

[0403] Step 310: Based on the request information from the network-side device, the UE reports this report list;

[0404] Step 311: The network-side equipment performs LTM / S-CPAC mobility optimization based on the report list.

[0405] It should be noted that in this embodiment, the LTM mentioned above is MCG LTM and / or SCG LTM. Success indicates that although the cell change was successfully executed, a critical failure occurred.

[0406] Figure 6 above shows that handover / PSCell change SHR records for adjacent source cells and target cells are recorded in the same entry. For handover / PSCell change SHR records for cells that are not adjacent source cells and target cells, they can also be recorded in the same entry, which will not be elaborated here (Figure 6 is based on SHR, and the same applies to RLF reports, which will not be elaborated here).

[0407] This embodiment uses the MCG-side RLF report / SHR as an example for illustration, but it is also applicable to the SCG-side SCGFailureInformation / SPR.

[0408] In embodiments of this disclosure, the terminal records success and failure information of continuous cell changes in different report lists and reports them to the network side, enabling the network side to perform network optimization based on the report lists.

[0409] Example 3: After the terminal performs continuous cell changes, it uses a brand-new report to record the success and / or failure information of the continuous cell changes. For example, it introduces a brand-new report to record LTM / S-CPAC related information (success / failure), instead of recording based on the traditional RLF report / SHR / SCGFailureInformation / SPR.

[0410] This new report can contain the same information as the report list in Example 1, and can also include some content related to LTM / S-CPAC.

[0411] In some embodiments, the terminal records success and / or failure information for the continuous cell changes, which can be done in a list-based or non-list-based manner. If recorded in a list-based manner, each entry in the list can record one success / failure message, and successes and failures can be recorded in different lists or in the same list. If recorded in a non-list-based manner, the report can include multiple success and failure messages, or multiple success and failure messages can be recorded in different reports.

[0412] Example 4: The method by which the terminal reports success and / or failure information for the continuous cell changes.

[0413] To avoid overriding, one approach is for the UE to immediately report a success / failure to the network-side device each time a report is generated. Specific methods include one or more of the following:

[0414] (1) After the UE sends the reconfiguration completion message, it actively sends the stored report to the network-side device. When the UE successfully accesses a cell, if a new report is generated, the UE actively sends the report to the network-side device after sending the reconfiguration completion message, without requiring a request from the network side. The report may be, for example, the first report list, or the second report list and / or the third report list.

[0415] (2) The UE carries the report in the reconfiguration completion message (if the report has already been generated at this time); when the UE successfully accesses a cell, if a new report that can be sent is generated, the UE will include the report in the reconfiguration completion message and send it together with the network side device when sending the reconfiguration completion message.

[0416] (3) Network-side device implementation guarantee: When the network-side device receives the reconfiguration completion message sent by the UE, it carries an indication information on the availability of the report. The network-side device can immediately request the UE to report this report.

[0417] (4) The UE sends an indication message indicating the tendency to report; when the UE has stored new reports that can be reported, such as reports that need to be reported urgently (reports related to LTM / S-CPAC), the UE can send an indication message to the network side device, indicating the UE's tendency to report this report. When the network side device receives this tendency sent by the UE, the network side decides whether to request this report.

[0418] (5) Based on the network side indication information, the UE reports the report in real time; the network side device sends indication information to the UE, indicating that the UE can report the LTM / S-CPAC report in real time when it has stored it.

[0419] (6) Based on the network side indication information, the UE sends the tendency to report to the network side device; the network side device sends the indication information to the UE, indicating that when the UE has stored an LTM / S-CPAC report, it is inclined to report and send the report, as in the manner described in (4) above.

[0420] It should be noted that the above reports are LTM / S-CPAC success / failure related reports, such as enhanced RLF report / SHR / SCGFailureInformation message / SPR.

[0421] Example 5: A method for recording success and / or failure information when the terminal experiences other mobility issues.

[0422] In this embodiment, after releasing the LTM / S-CPAC configuration, if other mobility events (such as legacy L3 HO) occur, a new report is generated:

[0423] 1) A new report can override an old report or continue recording as an entry in an old report;

[0424] 2) After the LTM / S-CPAC configuration is released, the UE reports an indication to the network-side device, indicating that there is a report related to LTM / S-CPAC stored (a new indication can be introduced or a legacy indication can be reused), and waits for the network side to obtain it.

[0425] In some embodiments, during the LTM / S-CPAC configuration process, if other mobility occurs (such as legacy L3 HO), a new report is generated: the new report can override the old report or continue recording as an entry in the old report.

[0426] In embodiments of this disclosure, during high-frequency mobility (such as LTM, S-CPAC) processes, the terminal can record multiple failed / successful mobility-related information and report it to the network-side device. This avoids previously recorded failed / successful information being overwritten by new failed / successful information, thus preventing information loss and enabling the UE to provide more information for network optimization.

[0427] As shown in Figure 7, this disclosure provides a method for reporting mobility reports, applied to network-side devices, including:

[0428] Step 701: The network-side device receives success and / or failure information of continuous cell change reported by the terminal; wherein, the continuous cell change is LTM or S-CPAC.

[0429] In this embodiment, the continuous cell change refers to a cell change configured with LTM and / or S-CPAC, where the configuration is not released after the cell change is performed. The continuous cell change can be a cell change with high-frequency mobility, such as LTM and / or S-CPAC, where S-CPAC can also be represented as subsequent CPAC. It should be noted that the continuous cell change can also be other cell changes with high-frequency mobility besides LTM and / or S-CPAC.

[0430] The terminal performs continuous cell change (LCM) and records success and / or failure information for the LTM, then reports the recorded information to the network-side equipment. For example, the terminal performs LTM, records its success and / or failure information, and reports this information; or, the terminal performs S-CPAC, records its success and / or failure information, and reports this information. The network-side equipment can perform network optimization based on the success and / or failure information reported by the terminal for the LTM.

[0431] As an optional embodiment, the success information and / or failure information of continuous cell changes reported by the receiving terminal includes:

[0432] The receiving terminal reports a first report list, which records success and / or failure information of continuous cell changes.

[0433] or,

[0434] The receiving terminal reports a second report list and / or a third report list. The second report list records successful information of continuous cell changes, and the third report list records failed information of continuous cell changes. The second report list and the third report list are two different report lists.

[0435] In this embodiment, when the terminal has successful and / or failed information regarding continuous cell changes, or when successful and / or failed information regarding continuous cell changes is generated, it can record the success and failure information in the same report list (the first report list). That is, regardless of whether the continuous cell change is executed successfully or fails, the relevant results can be recorded in the first report list. When the terminal reports continuous cell change information to the network-side device, it reports the first report list. Alternatively, when the terminal has successful and / or failed information regarding continuous cell changes, or when successful and / or failed information regarding continuous cell changes is generated, it can record the success and failure information separately in different report lists. For example, the terminal records the successful information regarding continuous cell changes in the second report list and the failed information in the third report list. When the terminal reports continuous cell change information to the network-side device, it reports the second report list and / or the third report list.

[0436] It should be noted that each report in the first report list, the second report list, and / or the third report list can be a new report or a traditional report (e.g., failure information can be recorded in an RLF report, and success information can be recorded in an SHR or SPR report). For example, each report in the first report list, the second report list, and / or the third report list can be a newly introduced report to record success and / or failure information of LTM / S-CPAC, i.e., not based on RLF report / SHR / SCGFailureInformation / SPR report records of related technologies.

[0437] It should be noted that the second report and the third report do not need to be recorded simultaneously; that is, the terminal records the second report and the third report as separate and independent processes.

[0438] In some embodiments, each entry in the first report list is used to record one successful or one failed cell change;

[0439] Each entry in the second report list is used to record one successful instance of a continuous cell change, and each entry in the third report list is used to record one failed instance of a continuous cell change.

[0440] In this embodiment, each entry in the first report list includes one success or failure message. The success or failure message recorded in each entry can be an SHR, SPR, or RLF report. For example, the first entry in the first report list records a continuous cell change success message (SHR), the second entry records a continuous cell change success message (SHR), and the third entry records a continuous cell change failure message (RLF report).

[0441] The second report list is used only to record successful information of continuous cell changes, so each entry includes one success message, which can be an SHR or SPR; the third report list is used only to record failed information of continuous cell changes, so each entry includes one failure message, which can be an RLF report.

[0442] In this embodiment, the recording method for the success and / or failure information of continuous cell changes can be in list form or non-list form. If recorded in list form, each entry in the list is not recorded as a report, but only each success and / or failure information is recorded in each entry of the list. This recording method can be to record success and failure in one list or in different lists. If recorded in non-list form, this report can include multiple success and failure information, or multiple success and multiple failure information can be recorded in different reports.

[0443] In some embodiments, the success and / or failure information of the continuous cell changes reported by the terminal includes success or failure information of the Mth cell change that meets a first condition. The first condition includes: at least one change has been performed between the source cell and the target cell of the Mth cell change, and the terminal has recorded success and / or failure information for the change from the source cell to the target cell.

[0444] Among the success and / or failure information of the continuous cell changes, the success or failure information of the Mth cell change can be recorded independently, or the number of occurrences corresponding to the Mth cell change can be recorded.

[0445] In some embodiments, when recording the number of occurrences corresponding to the cell change, the number of occurrences can be counted together for both success and failure information, or the number of occurrences can be counted separately for each type of information.

[0446] In this embodiment, for two (or more) handovers / PSCell changes of the same source cell and target cell, the terminal can record the results of several cell changes in different entries, or it can record the results of several cell changes in the same entry and record the number of times. For example, it can record the number of times the cell change from cell 1 to cell 2 failed or the number of times the critical failure occurred.

[0447] As an optional embodiment, the success information and / or failure information of continuous cell changes reported by the receiving terminal includes: a first report reported by the receiving terminal, wherein the first report records one success information or one failure information of continuous cell changes.

[0448] In this embodiment, the terminal can immediately report relevant information to the network-side device after recording success or failure information for each cell change. For example, if the terminal performs an LTM cell change and the change is successful, the terminal records the success information of this LTM cell change and reports the success information of this LTM cell change to the network-side device.

[0449] As an optional embodiment, the first report list includes at least one of the following:

[0450] The first time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the release of the configuration information;

[0451] The second time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the update of the configuration information;

[0452] The terminal receives the cell identifier of the configuration information for the continuous cell changes;

[0453] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is released;

[0454] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is updated;

[0455] The third time interval is the time interval between the last time the terminal received the configuration information for continuous cell changes and the time interval between the terminal reporting the report list.

[0456] The fourth time interval is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list;

[0457] The fifth time interval is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list;

[0458] And / or, the second report list includes at least one of the following:

[0459] The first time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the release of the configuration information;

[0460] The second time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the update of the configuration information;

[0461] The terminal receives the cell identifier of the configuration information for the continuous cell changes;

[0462] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is released;

[0463] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is updated;

[0464] The third time interval is the time interval between the last time the terminal received the configuration information for continuous cell changes and the time interval between the terminal reporting the report list.

[0465] The fourth time interval is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list;

[0466] The fifth time interval is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list;

[0467] And / or, the third report list includes at least one of the following:

[0468] The first time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the release of the configuration information;

[0469] The second time interval is the time interval between the terminal receiving the configuration information of the continuous cell change and the update of the configuration information;

[0470] The terminal receives the cell identifier of the configuration information for the continuous cell changes;

[0471] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is released;

[0472] The cell identifier corresponding to the terminal when the configuration information of the continuously changing cells is updated;

[0473] The third time interval is the time interval between the last time the terminal received the configuration information for continuous cell changes and the time interval between the terminal reporting the report list.

[0474] The fourth time interval is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list;

[0475] The fifth time interval is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list.

[0476] In this embodiment, 1) a first time interval, the first time interval being the time interval between the terminal receiving the configuration information of the continuous cell change and the release of the configuration information; for example: the first time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the release of the configuration.

[0477] 2) Second time interval, which is the time interval between the terminal receiving the configuration information of the continuous cell change and the configuration information being updated; for example, the second time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the configuration being updated.

[0478] 3) The cell identifier of the continuously changing cell configuration information received by the terminal; for example, it could be the cell identifier information of the cell to which the terminal is connected when it receives the latest LTM configuration / S-CPAC configuration. Another example: it could be the cell identifier information of the cell to which the terminal is connected when it first receives the LTM configuration / S-CPAC configuration.

[0479] 4) The cell identifier corresponding to the terminal when the configuration information of the continuous cell change is released; for example, the cell identifier information of the cell connected when releasing the LTM configuration / S-CPAC configuration.

[0480] 5) The cell identifier corresponding to the terminal when the configuration information of the continuous cell change is updated; for example, the cell identifier information of the connected cell when updating the LTM configuration / S-CPAC configuration.

[0481] 6) A third time interval, which is the time interval between the terminal's most recent receipt of configuration information for continuous cell changes and the terminal's submission of a report list; for example, the third time interval is the time interval between the terminal receiving the latest LTM configuration / S-CPAC configuration and the submission of the report list for this continuous cell change. The report list can be any one of the first report list, the second report list, and the third report list.

[0482] 7) A fourth time interval, which is the time interval between the first failure of the continuous cell change execution and the terminal reporting the report list; for example, the fourth time interval is the time interval between the first failure of the terminal's LTM / S-CPAC execution and the reporting of the continuous cell change report list. The report list can be a first report list or a third report list.

[0483] 8) A fifth time interval, which is the time interval between the first successful execution of the continuous cell change and the terminal reporting the report list. For example, this fifth time interval is the time interval between the first successful execution of LTM / S-CPAC and the reporting of the report list for this continuous cell change. The report list can be a first report list or a second report list.

[0484] As an optional embodiment, the success and / or failure information of continuous cell changes reported by the receiving terminal includes at least one of the following:

[0485] (1) After receiving the reconfiguration completion message sent by the receiving terminal, the receiving terminal reports the success information and / or failure information of the continuous cell change.

[0486] In this embodiment, after performing continuous cell changes, the terminal sends a reconfiguration completion message to the network-side device. Following the reconfiguration completion message, the terminal proactively reports success and / or failure information of the continuous cell changes to the network-side device, for example, by sending a stored first report list, second report list, or third report list. Upon receiving the reconfiguration completion message, the network-side device receives the success and / or failure information of the continuous cell changes.

[0487] In some embodiments, during this process, the terminal may report the success information and / or failure information of the continuous cell change based on the network side configuration, that is, based on the first indication information sent by the network side device in (3) (used to instruct the terminal to report the success information and / or failure information of the continuous cell change when the success information and / or failure information of the continuous cell change are stored).

[0488] (2) Receive a reconfiguration completion message sent by the terminal, wherein the reconfiguration completion message carries success information and / or failure information of the continuous cell change;

[0489] In this embodiment, after performing consecutive cell changes, the terminal sends a reconfiguration completion message to the network-side device. This message may include recorded success and / or failure information for the consecutive cell changes. For example, it may include a first report list, a second report list, or a third report list. The network-side device can obtain the success and / or failure information for the consecutive cell changes based on the received reconfiguration completion message.

[0490] (3) Send a first instruction information to the terminal and receive the success information and / or failure information of the continuous cell change reported by the terminal according to the first instruction information. The first instruction information is used to request the terminal to report the success information and / or failure information of the continuous cell change, or the first instruction information is used to instruct the terminal to report the success information and / or failure information of the continuous cell change when it has stored the success information and / or failure information of the continuous cell change.

[0491] In this embodiment, the network-side device may send a first indication message to the terminal, requesting or instructing the terminal to report the success and / or failure information of the continuous cell changes; or, the network-side device may send a first indication message to the terminal, instructing the terminal to report the success and / or failure information of the continuous cell changes immediately when it has stored such information. The terminal may report the success and / or failure information of the continuous cell changes based on the request or indication from the network-side device.

[0492] (4) Receive a second indication information sent by the terminal, the second indication information being used to indicate that the terminal expects to report the success information and / or failure information of the continuous cell change;

[0493] In this embodiment, the terminal can send a second indication message to the network-side device to indicate that the terminal has a tendency to send a report. The UE can send the indication message to the network-side device to indicate the tendency to report this report. When the network side receives this tendency sent by the terminal, the network side decides whether to request this report. In this embodiment, the second indication message can be reported by the terminal based on the configuration of the network-side device, that is, the terminal reports the second indication message based on the third indication message in (5).

[0494] (5) Send a third indication information to the terminal, the third indication information being used to instruct the terminal, if it has stored the success information and / or failure information of the continuous cell change, to report whether it expects to send the success information and / or failure information of the continuous cell change.

[0495] In this embodiment, the network-side device can send a third indication to the terminal, instructing the terminal to report its tendency to send a report when it stores success and / or failure information for consecutive cell changes. The network side can decide whether to request this report based on the terminal's reported tendency to send a report.

[0496] (6) Network implementation method: When the target cell determines that the terminal has undergone continuous cell change, after the terminal successfully accesses the target cell, the target cell sends a request message to the terminal to request the terminal to report the information of success and / or failure of continuous cell change. The terminal reports the information of success and / or failure of continuous cell change based on the request from the network side (if the terminal side stores such information).

[0497] In some embodiments, the method further includes: receiving a fourth report list reported by the terminal, wherein the fourth report list records other mobility success information or failure information;

[0498] or,

[0499] The receiving terminal reports a first report list, a second report list, or a third report list, which includes independently recorded success or failure information for other mobility activities.

[0500] In this embodiment, other mobility activities include legacy L3 HO, CHO, traditional PSCell addition / change, CPAC, etc. When other mobility activities occur at the terminal, mobility success or failure information can be recorded in a new report (such as the fourth report list). In some embodiments, the new report can override the old report (an already stored report or report list); or, it can continue to be recorded as a separate entry in the old report (an already stored report or report list).

[0501] As an optional embodiment, the method further includes:

[0502] When the configuration information for the continuous cell changes is released, the updated configuration information for the continuous cell changes is sent to the terminal.

[0503] The terminal receives a fourth instruction and / or a fifth instruction, wherein the fourth instruction indicates that the terminal expects to report the first report list, the second report list, or the third report list; and the fifth instruction indicates that the terminal stores the first report list, the second report list, or the third report list.

[0504] In this embodiment, after the configuration information of the continuous cell change is released, the network-side device can send new configuration information of the continuous cell change to the terminal. The terminal performs a first operation based on the new configuration information, such as generating a new report list (such as the fifth report list) based on the new configuration, recording the cell change success information and / or failure information corresponding to the new configuration in the new report list, and reporting it to the network side.

[0505] In some embodiments, after receiving a new continuous cell change configuration, the terminal can directly release the report or report list generated based on the old configuration information, such as releasing the first report list, the second report list, or the third report list.

[0506] In some embodiments, after receiving a new continuous cell change configuration, the terminal may report a fourth indication to the network-side device, indicating that the terminal has a tendency to report a stored report list (such as a first report list, a second report list, or a third report list); or, report a fifth indication to the network-side device, indicating that the terminal has stored the aforementioned report list, so that the network side decides whether to request the report list.

[0507] As an optional embodiment, the method further includes:

[0508] The terminal receives a sixth indication message, which instructs the terminal to store the success information and / or failure information of the continuous cell change. The sixth indication message is sent by the terminal when the configuration information of the continuous cell change is released.

[0509] In this embodiment, after releasing the configuration information for continuous cell changes, the terminal can report a sixth indication to the network-side device, indicating that the terminal stores the success information and / or failure information of the continuous cell changes, so that the network side can decide whether to request the success information and / or failure information of the continuous cell changes. The success information and / or failure information of the continuous cell changes can refer to a report or a report list in which the terminal records the success information and / or failure information of the continuous cell changes.

[0510] In embodiments of this disclosure, the terminal performs continuous cell changes and records success and / or failure information for the continuous cell changes, and reports the recorded success and / or failure information to the network-side device.
