[0237] In some embodiments, the wireless communication method 200 further includes:

[0238] The terminal sends first information to the first network device;

[0239] The first information includes at least one of the following:

[0240] The ninth indication information is used to indicate that the terminal has performed a prediction-based conditional handover, or to indicate that the terminal has applied a prediction-based conditional handover configuration during the RRC re-establishment process;

[0241] A prediction method, wherein the prediction method includes one of the following: predicting RRM measurement results, predicting measurement event results, and predicting target cells.

[0242] Optionally, the terminal may also send the first information to a second network device.

[0243] In this embodiment, after executing S210 above, the terminal sends first information to the first network device, so that the first network device can know that the terminal has performed a prediction-based conditional handover, or the first network device can know that the terminal has applied a prediction-based conditional handover configuration during the RRC re-establishment process, so that the first network device can perform network optimization.

[0244] In some embodiments, the wireless communication method 200 further includes:

[0245] The terminal sends the second information to the first network device;

[0246] The second information includes, but is not limited to, at least one of the following:

[0247] The request information is used to request network-side configuration information based on prediction-based conditional switching.

[0248] Preference information based on predicted conditional switching;

[0249] Information about at least one predicted candidate cell;

[0250] Information on at least one candidate cell preferred by the terminal;

[0251] The predicted probability of switching to some or all of the candidate cells in the at least one candidate cell;

[0252] Predicted handover time information for some or all of the at least one candidate cells;

[0253] The predicted trajectory information of the terminal;

[0254] Predicted RRM measurement results;

[0255] Predicted measurement event outcomes;

[0256] The predicted target community.

[0257] In this embodiment, before S210, the terminal sends second information to the first network device, which can assist the network side in generating or preparing configuration information for condition switching. Based on the predicted information, the network side can prepare the configuration information for condition switching in advance without waiting for the terminal to report the actual measurement results.

[0258] In this embodiment, the second information is obtained by the terminal based on prediction or inference by the AI ​​unit. For example, the terminal obtains the second information based on the RRM prediction AI unit or the measurement event prediction AI unit. Alternatively, the terminal directly obtains the second information based on the handover prediction AI unit or the conditional handover prediction AI unit, or the terminal directly obtains the candidate cells for handover based on the handover prediction AI unit or the conditional handover prediction AI unit.

[0259] Optionally, the information requested by the network side to configure conditional handover based on prediction includes: information requested by the network side to configure conditional handover based on predicted RRM measurement results, information requested by the network side to configure conditional handover based on predicted measurement event results, or information requested by the network side to configure conditional handover based on predicted target cell.

[0260] Optionally, the preference information for conditional handover based on prediction includes: preference for conditional handover based on predicted RRM measurement results, preference for conditional handover based on predicted measurement event results, or preference for conditional handover based on predicted target cell.

[0261] For example, the information of the predicted at least one candidate cell can be the identifier of the predicted at least one candidate cell. For instance, the terminal, based on its AI unit, predicts at least one possible candidate cell and recommends it to the network side. Based on the terminal's recommendation, the network side can more accurately select candidate cells for handover.

[0262] For example, the information about at least one candidate cell preferred by the terminal can be the identifier of at least one candidate cell. For instance, the terminal predicts at least one candidate cell preferred by the terminal based on an AI unit and recommends it to the network side. Based on the terminal's recommendation, the network side can more accurately select candidate cells for handover.

[0263] For example, the predicted probability of switching to some or all of the candidate cells in at least one candidate cell can be the probability of the terminal switching to a candidate cell based on the prediction of the AI ​​unit.

[0264] For example, the predicted timing information for switching to some or all of the candidate cells in at least one candidate cell can be the time or time window for the terminal to switch to the candidate cell based on AI unit prediction.

[0265] For example, the predicted trajectory information of the terminal can be the geographical locations traversed over a period of time, or a list of cells passed through, along with relevant time points. Generally, trajectory prediction is over a longer period, making it suitable for conditional handover. Network-side devices can generate conditional handover configuration information based on the predicted terminal trajectory information; for instance, the network-side device can configure cells near the terminal's trajectory information as candidate cells.

[0266] It should be noted that the predicted probability of handover to some or all of the candidate cells in at least one candidate cell and the predicted time information of handover to some or all of the candidate cells in at least one candidate cell can also be the probability of handover to a certain cell within the time or time window indicated by the time information, or the distribution of handover probability at different times (i.e., the distribution of the probability of handover to a certain cell at different times).

[0267] In some embodiments, the at least one candidate cell includes at least one of the following: a candidate primary cell and a candidate secondary cell; wherein the predicted probability of handover to some or all of the at least one candidate cell includes at least one of the following:

[0268] The predicted probability of switching to candidate primary and secondary cells;

[0269] The predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell;

[0270] The predicted probability of switching to the candidate primary cell when switching to the candidate primary cell associated with the candidate primary / secondary cell.

[0271] It should be noted that switching to the candidate primary cell associated with the candidate primary cell can be understood as simultaneously switching to both the candidate primary cell associated with the candidate primary cell and the candidate primary cell associated with the candidate primary cell, or switching to the candidate primary cell associated with the candidate primary cell first, and then switching to the candidate primary cell.

[0272] For example, the predicted probability of switching to a candidate primary / secondary cell is P, the predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell is P1, and the predicted probability of switching to the candidate primary / secondary cell when switching to the candidate primary cell associated with the candidate primary / secondary cell is P2, where P = P1 * P2.

[0273] For example, as shown in Table 2, there are two candidate cells for conditional handover (candidate primary cell 1 and candidate primary cell 2), and the predicted probabilities of handover to each candidate cell are as follows:

[0274] candidate PCell 1: 50%;

[0275] Candidate PCell 2: 50%.

[0276] As shown in Table 2, there are three candidate primary and secondary cells (candidate PSCells) associated with candidate PCell 1: {candidate PSCell A, candidate PSCell B, and candidate PSCell C}. The probabilities of reaching each candidate primary and secondary cell after reaching the candidate primary cell (candidate PCell 1) associated with this candidate primary and secondary cell are as follows: candidate PSCell A: 60%, candidate PSCell B: 20%, and candidate PSCell C: 20%.

[0277] Therefore, the estimated probability of reaching candidate PSCell 1 is 50% * 60 * = 30%.

[0283] The third information is used to indicate candidate cells for potential conditional handover, or the third information is used to indicate candidate cells for conditional handover that are allowed to be reported.

[0284] The at least one candidate cell is determined based on the third information.

[0285] In this embodiment, the terminal can determine at least one candidate cell in the second information based on the candidate cells for conditional handover of potential deployment indicated by the third information, or the terminal can determine at least one candidate cell in the second information based on the candidate cells for conditional handover that are allowed to be reported, indicated by the third information.

[0286] Optionally, the third information can be candidate cell filtering configuration. For example, the first network device configures the candidate cell filtering configuration through measurement configuration information.

[0289] The terminal performs condition switching at the predicted condition switching time;

[0290] When the execution conditions for the predicted condition switching are met, the terminal performs the condition switching at the first time, wherein the first time is the time when the execution conditions for the predicted condition switching are met, or the first time is a time elapsed before the time when the execution conditions for the predicted condition switching are met.

[0291] When the execution conditions for predicting condition switching are met, the terminal performs condition switching when the entry condition of the measurement event corresponding to the execution conditions for condition switching is met.

[0292] For example, the first time t2 = max{t0, t1 - first duration}, where t0 is the current time and t1 is the time when the execution condition for the prediction condition switching is met.

[0293] Optionally, the first duration is the time to trigger (TTT), which is the TTT included in the configuration of the measurement event corresponding to the execution condition. It can be understood that the time when the execution condition for the predicted condition switching is met is t1, and the current time is t0. Specifically, when t1 - the first duration <= t0, t2 = t0, that is, when it is predicted that the execution condition is met, the condition switching is executed immediately.

[0294] It should be understood that the time when the execution conditions of the terminal during the prediction condition switching are met can be understood as the moment when the execution conditions of the terminal during the prediction condition switching are met (i.e., a point in time), or the time unit (such as a symbol, time slot, etc.) when the execution conditions of the terminal during the prediction condition switching are met.

[0295] In some embodiments, the entering conditions of the measurement event corresponding to the execution conditions of the condition switching are satisfied based on the actual measurement results, or the entering conditions of the measurement event corresponding to the execution conditions of the condition switching are satisfied based on the predicted measurement results.

Alternatively, for consecutive LTMs: the terminal executes conditional LTMs multiple times based on the network configuration's candidate LTM configuration.

[0469] The third network device sends a seventh message to the second network device; wherein the seventh message includes configuration information for conditional switching, and the configuration information for conditional switching is determined based on the sixth message.

[0470] The technical solution of this application is described in detail below through specific embodiments.

[0471] Example 1, as Figure 6 As shown, it may specifically include some or all of S1-1 to S1-5. The main idea of ​​Embodiment 1 is that the network side configures conditional switching based on prediction information, so that the network side can configure conditional switching based on the terminal's prediction, thereby achieving better resource allocation and improving resource utilization efficiency.

[0472] S1-1. The terminal sends information 11 to the source MN;

[0473] The information 11 includes at least one of the following:

[0474] Information about at least one predicted candidate cell (such as cell identifier);

[0475] Information about at least one candidate cell preferred by the terminal (such as cell identifier);

[0476] The predicted probability of switching to some or all of the candidate cells in at least one candidate cell;

[0477] Predicted handover timing information for at least some or all of the candidate cells in at least one candidate cell;

[0478] Predicted trajectory information of the terminal;

[0479] Predicted RRM measurement results;

[0480] Predicted measurement event outcomes;

[0481] The target cell for the predicted conditional handover.

[0482] It should be noted that information 11 can correspond to the second information mentioned above.

[0483] Specifically, information 11 above is an optional step.

[0484] Specifically, the information 11 is used by the terminal to report the prediction results to assist the network side in preparing the configuration for condition switching.

[0485] For example, the terminal predicts possible candidate cells (i.e., at least one candidate cell) based on the AI ​​unit and recommends them to the network side. Based on the terminal's recommendation, the network side can more accurately select candidate cells for condition handover.

[0486] For example, the terminal indicates the predicted probability of switching to some or all of the candidate cells in at least one candidate cell via information 11.

[0487] For example, the terminal instructs via information 11 to switch to the predicted time or predicted time window of some or all of the candidate cells in at least one candidate cell.

[0488] For example, the network side can configure the terminal with prediction-based conditional handover based on predicted RRM measurement results, predicted measurement event results, predicted target cells for conditional handover, etc.

[0489] For example, the predicted trajectory information of the terminal can be the geographical locations it passes through over a period of time, or a list of cells it passes through, along with relevant time points. Generally, trajectory prediction is over a relatively long period, making it suitable for conditional handover. The network side configures conditional handover based on the predicted trajectory information; for example, it configures cells near the trajectory as candidate cells.

[0490] The aforementioned probability and time information can also be the probability of switching to a certain cell within the time or time window indicated by the time information, or the distribution of the switching probability at different times (i.e., the distribution of the probability of switching to a certain cell at different times).

[0491] Optionally, the information 11 is obtained by the terminal based on the AI ​​unit. For example, the terminal obtains the information 11 based on the RRM prediction AI unit or the measurement event prediction AI unit. Alternatively, the terminal directly obtains the information 11 or the candidate cell for handover (i.e., at least one candidate cell) based on the handover prediction AI unit or the conditional handover prediction AI unit.

[0492] Specifically, the network side can prepare the condition switching configuration in advance based on information 11, without waiting for the terminal to report the actual measurement results.

[0493] S1-2. The source MN (also known as the source base station) sends information 12 to the target MN;

[0494] The information 12 includes at least one of the following:

[0495] Information on M candidate cells;

[0496] The predicted probability of switching to some or all of the M candidate cells;

[0497] Predicted handover time information for some or all of the M candidate cells;

[0498] Predicted trajectory information of the terminal;

[0499] Predicted RRM measurement results;

[0500] Predicted measurement event outcomes;

[0501] The target cell for the predicted conditional handover.

[0502] It should be noted that information 12 can correspond to the fourth information mentioned above.

[0503] Optionally, the source MN can determine information 12 based on the information 11 above.

[0504] For example, the source MN determines M candidate cells based on the predicted trajectory information of the terminal.

[0505] For example, the source MN determines the probability of switching to some or all of the candidate cells among the M candidate cells based on the predicted probability of switching to some or all of the candidate cells among at least one candidate cell; or, the source MN determines the probability of switching to some or all of the candidate cells among the M candidate cells based on the predicted trajectory information of the terminal, the predicted RRM measurement results, the predicted measurement event results, the predicted target cell for conditional handover, etc.; or, the source MN obtains the probability of switching to some or all of the candidate cells among the M candidate cells based on AI unit inference or prediction.

[0506] For example, the source MN determines the timing information for handover to some or all of the candidate cells in M ​​candidate cells based on the predicted handover timing information for handover to some or all of the candidate cells in at least one candidate cell.

[0507] Optionally, the information 12 includes the aforementioned information (such as probability or time information) for switching to the candidate primary cell (PCell) and / or the aforementioned information (such as probability or time information) for switching to the candidate primary secondary cell (PSCell).

[0508] S1-3. The target MN sends information 13 (same as information 12, but applied to candidate SN, candidate primary / secondary cell (PSCell) or secondary cell group (SCG)) to the target SN to indicate auxiliary information for adding or switching to a secondary node or candidate primary / secondary cell.

[0509] Optionally, the information 13 includes at least one of the following:

[0510] Information on N candidate cells;

[0511] The predicted probability of switching to some or all of the N candidate cells;

[0512] Predicted handover time information for some or all of the N candidate cells;

[0513] Predicted trajectory information of the terminal;

[0514] Predicted RRM measurement results;

[0515] Predicted measurement event outcomes;

[0516] The target cell for the predicted conditional handover;

[0517] Where N is a positive integer.

[0518] It should be noted that information 13 can correspond to the seventh information mentioned above.

[0519] Specifically, information 13 above is an optional step.

[0520] For example, for a conditional handover (CHO) with candidate SCG: the source MN sends information 12 to the target MN, which includes prediction information for both the primary and secondary cells. The target MN sends information 13 to the target SN, which includes prediction information for the candidate primary and secondary cells.

[0521] Optionally, the at least one candidate cell includes at least one of the following: a candidate primary cell and a candidate secondary cell; wherein, the predicted probability of handover to some or all of the candidate cells in the at least one candidate cell includes at least one of the following:

[0522] The predicted probability of switching to a candidate primary / secondary cell (P), the predicted probability of switching to the candidate primary / secondary cell associated with the candidate primary / secondary cell (P1), and the predicted probability of switching to the candidate primary / secondary cell and then switching back to the candidate primary / secondary cell (P2).

[0523] Optionally, the M candidate cells include at least one of the following: candidate primary cells, candidate secondary cells; wherein, the predicted probability of handover to some or all of the M candidate cells includes at least one of the following:

[0524] The predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell (P1), and the predicted probability of switching to the candidate primary / secondary cell when switching to the candidate primary / secondary cell associated with the candidate primary / secondary cell (P2).

[0525] Optionally, the N candidate cells include at least one of the following: candidate primary cells and candidate secondary cells;

[0526] The predicted probability of switching to some or all of the N candidate cells includes at least one of the following:

[0527] The predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell (P1), and the predicted probability of switching to the candidate primary / secondary cell when switching to the candidate primary / secondary cell associated with the candidate primary / secondary cell (P2).

[0528] Optionally, the probability can be calculated by UE or MN: P = P1 * P2.

[0529] For example, as shown in Table 2 above, there are two candidate cells for conditional handover (candidate primary cell 1 (candidatePCell1) and candidate primary cell 2 (candidatePCell2)), and the predicted probabilities of handover to each candidate cell are as follows:

[0530] candidate PCell 1: 50%;

[0531] Candidate PCell 2: 50%.

[0532] As shown in Table 2 above, there are three candidate primary and secondary cells (candidate PSCells) associated with candidate PCell 1: {candidate PSCell A, candidate PSCell B, and candidate PSCell C}. The probabilities of reaching each candidate primary and secondary cell after reaching the candidate primary cell (candidate PCell 1) associated with this candidate primary and secondary cell are as follows: candidate PSCell A: 60%, candidate PSCell B: 20%, and candidate PSCell C: 20%.

[0533] Therefore, the estimated probability of reaching candidate PSCell 1 is 50% * 60 * = 30%.

[0534] S1-4. The target MN receives information 14 from the target SN, wherein the information 14 includes configuration information for condition switching, which is determined based on the information 13.

[0535] Specifically, information 14 above is an optional step.

[0536] It should be noted that information 14 can correspond to the seventh information mentioned above.

[0537] S1-5. The target MN (in dual-connection mode, the target master node) sends a handover request confirmation message to the source MN (if in dual-connection mode, the source master node). The handover request confirmation message is determined based on the aforementioned information 12 and / or information 13. It can be understood that the network side configures conditional handover based on predictive information, resulting in a more accurate estimation of the probability of the terminal reaching the target MN, enabling better resource allocation and improved resource utilization efficiency.

[0538] Example 2, as Figure 7 As shown, it may specifically include some or all of S2-1 to S2-8. The main idea of ​​Embodiment 2 is that the terminal evaluates or performs conditional handover based on predictive information, such as RRM measurement prediction, measurement event measurement, or handover prediction. As a result, the network side configures conditional handover based on the predictive information, which makes the estimation of the probability of the terminal reaching the target MN more accurate, achieves better resource allocation, and improves resource utilization efficiency.

[0539] S2-1. The terminal sends information 21 to the source MN;

[0540] The information 21 includes at least one of the following:

[0541] The request information is used to request network-side configuration information based on prediction-based conditional switching.

[0542] Preference information based on predicted conditional switching;

[0543] Information about at least one predicted candidate cell (such as cell identifier);

[0544] Information about at least one candidate cell preferred by the terminal (such as cell identifier);

[0545] The predicted probability of switching to some or all of the candidate cells in at least one candidate cell;

[0546] Predicted handover timing information for at least some or all of the candidate cells in at least one candidate cell;

[0547] Predicted trajectory information of the terminal;

[0548] Predicted RRM measurement results;

[0549] Predicted measurement event outcomes;

[0550] The target cell for the predicted conditional handover.

[0551] It should be noted that the information 21 can correspond to the second information mentioned above.

[0552] This embodiment facilitates the network to configure prediction-based conditional handover based on the UE's requests or preferences.

[0553] Specifically, the above information 21 is an optional step.

[0554] Specifically, the information 21 is used by the terminal to report the prediction results to assist the network side in preparing the configuration for condition switching.

[0555] For example, the terminal predicts possible candidate cells (i.e., at least one candidate cell) based on the AI ​​unit and recommends them to the network side. Based on the terminal's recommendation, the network side can more accurately select candidate cells for condition handover.

[0556] For example, the terminal indicates the predicted probability of switching to some or all of the candidate cells in at least one candidate cell via information 21.

[0557] For example, the terminal instructs via information 21 to switch to the predicted time or predicted time window of some or all of the candidate cells in at least one candidate cell.

[0558] For example, the network side can configure the terminal with prediction-based conditional handover based on predicted RRM measurement results, predicted measurement event results, predicted target cells for conditional handover, etc.

[0559] For example, the predicted trajectory information of the terminal can be the geographical locations it passes through over a period of time, or a list of cells it passes through, along with relevant time points. Generally, trajectory prediction is over a relatively long period, making it suitable for conditional handover. The network side configures conditional handover based on the predicted trajectory information; for example, it configures cells near the trajectory as candidate cells.

[0560] The aforementioned probability and time information can also be the probability of switching to a certain cell within the time or time window indicated by the time information, or the distribution of the switching probability at different times (i.e., the distribution of the probability of switching to a certain cell at different times).

[0561] Optionally, the information 21 is obtained by the terminal based on the AI ​​unit. For example, the terminal obtains the information 21 based on the RRM prediction AI unit or the measurement event prediction AI unit. Alternatively, the terminal directly obtains the information 21 or the candidate cell for handover (i.e., at least one candidate cell) based on the handover prediction AI unit or the conditional handover prediction AI unit.

[0562] Specifically, the network side can prepare the configuration for condition switching in advance based on information 21, without waiting for the terminal to report the actual measurement results.

[0563] Optionally, the terminal receives candidate cell filtering configuration sent by the source MN, which indicates potentially deployed or allowed-to-report conditional handover candidate cells. For example, the candidate cell filtering configuration can be configured using MeasurementConfiguration information. The terminal reports the aforementioned information 21 based on the candidate cell filtering configuration.

[0564] It should be noted that the candidate cell filtering configuration can correspond to the third information mentioned above.

[0565] S2-2. The source MN (also known as the source base station) sends information 22 to the target MN (such as information 22 requesting the target MN to configure prediction-based conditional handover for the terminal);

[0566] The information 22 includes at least one of the following:

[0567] The request information is used to request network-side configuration information based on prediction-based conditional switching.

[0568] Preference information based on predicted conditional switching;

[0569] Information on M candidate cells;

[0570] The predicted probability of switching to some or all of the M candidate cells;

[0571] Predicted handover time information for some or all of the M candidate cells;

[0572] Predicted trajectory information of the terminal;

[0573] Predicted RRM measurement results;

[0574] Predicted measurement event outcomes;

[0575] The target cell for the predicted conditional handover.

[0576] It should be noted that information 22 can correspond to the fourth information mentioned above.

[0577] Optionally, the source MN can determine information 22 based on the information 21 above.

[0578] For example, the source MN determines M candidate cells based on the predicted trajectory information of the terminal.

[0579] For example, the source MN determines the probability of switching to some or all of the candidate cells among the M candidate cells based on the predicted probability of switching to some or all of the candidate cells among at least one candidate cell; or, the source MN determines the probability of switching to some or all of the candidate cells among the M candidate cells based on the predicted trajectory information of the terminal, the predicted RRM measurement results, the predicted measurement event results, the predicted target cell for conditional handover, etc.; or, the source MN obtains the probability of switching to some or all of the candidate cells among the M candidate cells based on AI unit inference or prediction.

[0580] For example, the source MN determines the timing information for handover to some or all of the candidate cells in M ​​candidate cells based on the predicted handover timing information for handover to some or all of the candidate cells in at least one candidate cell.

[0581] Optionally, the information 22 includes the aforementioned information (such as probability or time information) for switching to the candidate primary cell (PCell) and / or the aforementioned information (such as probability or time information) for switching to the candidate primary secondary cell (PSCell).

The target MN sends information 23 (same as information 22, but applied to candidate SN, candidate primary / secondary cell (PSCell) or secondary cell group (SCG)) to the target SN to indicate auxiliary information for adding or switching to a secondary node or candidate primary / secondary cell.

[0583] Optionally, the information 23 includes at least one of the following:

[0593] Where N is a positive integer.

[0594] It should be noted that information 23 can correspond to the sixth information mentioned above.

[0595] Specifically, information 23 above is an optional step.

[0596] For example, for a conditional handover (CHO) with candidate SCG: the source MN sends information 22 to the target MN, which includes prediction information for both the primary and secondary cells. The target MN sends information 23 to the target SN, which includes prediction information for the candidate primary and secondary cells.

[0597] Optionally, the at least one candidate cell includes at least one of the following: a candidate primary cell and a candidate secondary cell; wherein, the predicted probability of handover to some or all of the candidate cells in the at least one candidate cell includes at least one of the following:

[0599] Optionally, the M candidate cells include at least one of the following: candidate primary cells, candidate secondary cells; wherein, the predicted probability of handover to some or all of the M candidate cells includes at least one of the following:

[0600] The predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell (P1), and the predicted probability of switching to the candidate primary / secondary cell when switching to the candidate primary / secondary cell associated with the candidate primary / secondary cell (P2).

[0601] Optionally, the N candidate cells include at least one of the following: candidate primary cells and candidate secondary cells;

[0603] The predicted probability of switching to the candidate primary cell associated with the candidate primary / secondary cell (P1), and the predicted probability of switching to the candidate primary / secondary cell when switching to the candidate primary / secondary cell associated with the candidate primary / secondary cell (P2).

[0604] Optionally, the probability can be calculated by UE or MN: P = P1 * P2.

[0605] For example, as shown in Table 2 above, there are two candidate cells for conditional handover (candidate primary cell 1 (candidatePCell1) and candidate primary cell 2 (candidatePCell2)), and the predicted probabilities of handover to each candidate cell are as follows:

[0606] candidate PCell 1: 50%;

[0607] Candidate PCell 2: 50%.

[0608] As shown in Table 2 above, there are three candidate primary and secondary cells (candidate PSCells) associated with candidate PCell 1: {candidate PSCell A, candidate PSCell B, and candidate PSCell C}. The probabilities of reaching each candidate primary and secondary cell after reaching the candidate primary cell (candidate PCell 1) associated with this candidate primary and secondary cell are as follows: candidate PSCell A: 60%, candidate PSCell B: 20%, and candidate PSCell C: 20%.

[0609] Therefore, the estimated probability of reaching candidate PSCell 1 is 50% * 60 * = 30%.

[0642] Without loss of generality, the information 27 is carried in the RRC reconfiguration complete message.

[0643] Specifically, the above information 27 is an optional step.

[0644] It should be noted that the information 27 can correspond to the first information mentioned above.

[0645] Example 3, as Figure 8 As shown, it may specifically include some or all of S3-1 to S3-5. The main idea of ​​Embodiment 3 is that the terminal selects a suitable cell or applies the configured conditional handover candidate cell configuration based on predictive information, such as RRM measurement prediction, measurement event measurement, or handover prediction, to perform the RRC re-establishment process. Thus, the terminal performs the re-establishment process based on the predictive information to reduce the delay of the RRC re-establishment process and improve communication performance.

[0646] S3-1. The terminal sends information 31 to the source MN;

[0647] The information 31 includes at least one of the following:

[0648] The request information is used to request network-side configuration information based on prediction-based conditional switching.

[0649] Preference information based on predicted conditional switching;

[0650] Information about at least one predicted candidate cell (such as cell identifier);

[0651] Information about at least one candidate cell preferred by the terminal (such as cell identifier);

[0652] The predicted probability of switching to some or all of the candidate cells in at least one candidate cell;

[0653] Predicted handover timing information for at least some or all of the candidate cells in at least one candidate cell;

[0654] Predicted trajectory information of the terminal;

[0655] Predicted RRM measurement results;

[0656] Predicted measurement event outcomes;

[0657] The target cell for the predicted conditional handover.

[0658] It should be noted that the information 31 can correspond to the second information mentioned above.

[0659] This embodiment facilitates the network to configure prediction-based conditional handover based on the UE's requests or preferences.

[0660] Specifically, information 31 above is an optional step.

[0661] Specifically, the information 31 is used by the terminal to report the prediction results to assist the network side in preparing the configuration for condition switching.

[0662] For example, the terminal predicts possible candidate cells (i.e., at least one candidate cell) based on the AI ​​unit and recommends them to the network side. Based on the terminal's recommendation, the network side can more accurately select candidate cells for condition handover.

[0663] For example, the terminal indicates the predicted probability of switching to some or all of the candidate cells in at least one candidate cell via information 31.

[0664] For example, the terminal instructs via information 31 to switch to the predicted time or predicted time window of some or all of the candidate cells in at least one candidate cell.

[0665] For example, the network side can configure the terminal with prediction-based conditional handover based on predicted RRM measurement results, predicted measurement event results, predicted target cells for conditional handover, etc.

[0666] For example, the predicted trajectory information of the terminal can be the geographical locations it passes through over a period of time, or a list of cells it passes through, along with relevant time points. Generally, trajectory prediction is over a relatively long period, making it suitable for conditional handover. The network side configures conditional handover based on the predicted trajectory information; for example, it configures cells near the trajectory as candidate cells.

[0667] The aforementioned probability and time information can also be the probability of switching to a certain cell within the time or time window indicated by the time information, or the distribution of the switching probability at different times (i.e., the distribution of the probability of switching to a certain cell at different times).

[0668] Optionally, the information 31 is obtained by the terminal based on the AI ​​unit. For example, the terminal obtains the above information 31 based on the RRM prediction AI unit or the measurement event prediction AI unit. Alternatively, the terminal directly obtains the above information 31 or the candidate cell for handover (i.e., at least one candidate cell) based on the handover prediction AI unit or the conditional handover prediction AI unit.

[0669] Specifically, the network side can prepare the condition switching configuration in advance based on information 31, without waiting for the terminal to report the actual measurement results.
