[0046] In addition, to better understand the communication scheme provided in this application, the relevant technologies mentioned in this application are briefly introduced below.

[0047] 1. Artificial Intelligence (AI)

[0048] AI has been widely applied in various fields, such as integrating it into wireless communication networks to significantly improve technical indicators such as throughput, latency, and user capacity. Furthermore, integrating AI into wireless communication networks is also a crucial task for the future of wireless communication networks. Currently, AI units can be implemented in various ways, such as neural networks, decision trees, support vector machines, and Bayesian classifiers, etc., without limitation here.

This application does not specifically limit this.

[0051] 2. AI Mobility

[0052] R19 is discussing AI-based mobility enhancements, which could include RRM measurement prediction and measurement event prediction.

[0053] RRM measurement prediction includes predictions in the time, frequency, and spatial domains. Time-domain RRM measurement prediction is based on the historical RRM measurement results of a frequency point to predict the RRM measurement results of that frequency point at a future time point / time period. Frequency-domain RRM measurement prediction is based on the RRM measurement results of one frequency point to predict the RRM measurement results of another frequency point.

[0054] For measurement event (i.e., RRM measurement event) prediction, there are direct and indirect measurement event predictions. Direct measurement event prediction can be understood as follows: based on the RRM measurement results of a specific cell as input, the AI ​​unit outputs the probability of a measurement event occurring in that cell within a future period. Indirect measurement event prediction can be understood as follows: based on the RRM measurement results of a specific cell as input, the AI ​​unit outputs a predicted RRM measurement result for a future time point or time period. Post-processing of the predicted RRM measurement results is then used to determine whether the measurement event will occur at a future time point.

[0055] (3) RRM measurement reporting

[0056] For RRM measurement reporting, the measurement configuration involved mainly consists of the following a)-c).

[0057] a) Measurement Object (MeaObject, MO): It can be understood as the frequency point to be measured.

[0058] b) Report Configuration: It may include one or more of the following: reporting criteria (such as periodic reporting, event-triggered measurement reporting), reference signal type, measurement reporting quantity, whether to report beam measurement results, and the maximum number of beams that can be reported.

[0059] The reference signal type may include, but is not limited to, Synchronization Signal Block (SSB), Channel State Information Reference Signal (CSI-RS), etc.

[0060] The reported measurement may include, but is not limited to, one or a combination of one or more of the following: Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Interference-Ratio (SINR).

[0061] c) Measurement Identifier (measId): Used to associate a measurement object with a reporting configuration. A measurement object can be associated with multiple reporting configurations, and a reporting configuration can be associated with multiple measurement objects.

[0062] (4) Event-triggered RRM measurement reporting

[0063] Network-side devices can be configured to allow terminals to perform measurements and report based on measurement configurations. After a terminal performs a measurement and generates a measurement report (MeasReport, MR), it can trigger the reporting of the measurement report based on measurement events for several network configurations shown in Table 1 below. The parameters in Table 1 are explained below.

[0064] Ms represents the measurement results of the serving cell, without taking any offset into account.

[0065] Mn represents the measurement results of neighboring cells, without considering any offset.

[0066] Mp represents the measurement result of the primary cell (SpCell), without considering any offset.

[0067] Mi represents the result of the interference measurement, without taking any offset into account.

[0068] Ofn represents the neighboring cell measurement event offset; Ocn represents the neighboring cell-specific offset, both of which are configured by Radio Resource Control (RRC); if RRC is not configured, they can be set or the default value is 0.

[0069] Ofp represents the primary cell measurement event offset; Ocp represents the primary cell-specific offset, both of which are configured by RRC; if RRC is not configured, it is set to 0.

[0070] Hys represents the hysteresis parameter for this event, configured by RRC, with a value range of [0,30], and the actual value is the configured value * 0.5dB.

[0071] Off is the offset parameter for this event (such as a3-Offset defined in NR for this event's reportConfig).

[0072] Thresh is the threshold parameter for this event (i.e., the Threshold defined in the reportConfigNR for this event).

[0073] In the case of RSRP, Mn and Mp are expressed in dBm, or in the case of RSRQ and RS-SINR in dB. Ofn, Ocn, Ofp, Ocp, Hys, and Off are expressed in dB, and Thresh is expressed in the same unit as Mn.

[0074] Typically, the endpoint maintains a measurement configuration variable (VarMeasConfig) to store network measurement configurations, and a measurement report list variable (VarMeasReportList) to store triggered measurement reports. For each measurement identifier, the endpoint checks at least one of the following a)-e).

[0075] a) If the measurement report corresponding to the measurement identifier is configured for event-triggered reporting, and if the cell quality of one or more applicable cells after Layer (L)3 filtering meets the entry conditions of this event during the time-to-trigger (TTT) period, the terminal will include the measurement report entry corresponding to the measurement identifier in the VarMeasReportList, which includes the celltriggeredlist that triggered the measurement, and report the measurement report to the network.

[0076] Table 1

[0077] b) If the measurement reporting corresponding to the measurement identifier is configured as an event-triggered report, and the L3-filtered cell quality of one or more cells in the celltriggeredlist defined for this measurement identifier in the VarMeasReportList all meet the departure condition of this event during the TTT, then at least one of the following b1)-b3) can be performed.

[0078] b1) If enterLeavingReport is configured in the measurement report configuration corresponding to the measurement identifier, the cells that meet the requirements for leaving the event will be stored in cellsMetLeavingCond of the measurement report entry corresponding to this measurement identifier.

[0079] b2) Delete the relevant cells from cellsTriggeredList.

[0080] b3) If the reportOnLeave configuration of the measurement report corresponding to the measurement identifier is set to true, that is, the measurement report is reported when the cell meets the leave conditions, then the measurement report is reported to the network.

[0081] Taking the aforementioned RRM measurement event as an example, in related technologies, when a cell measurement meets the RRM measurement event, the terminal typically reports the RRM measurement for use by network-side equipment in handover decisions. However, due to factors such as measurement fluctuations, the cell quality obtained from the RRM measurement may differ from the actual cell quality during handover, leading to problems such as ping-pong handover and affecting communication system performance. To address this, this application provides a communication solution. For cells meeting the first event, by predicting which cells will leave the first event, cells whose cell quality may differ from the actual cell quality during handover due to measurement fluctuations can be identified, thus ensuring the performance of the communication system during subsequent cell handovers.

[0082] Based on this, the technical solutions provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0083] Figure 2 shows a flowchart of a communication method 200 provided in an exemplary embodiment of this application. This method 200 can be executed by, but is not limited to, a terminal, specifically by hardware and / or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.

[0084] S210, if the first cell satisfies the first event, the terminal predicts whether the first cell will leave the first event.

[0085] The first event may include, but is not limited to, at least one of RRM measurement events and predicted measurement events. The predicted measurement event represents a possible RRM measurement event based on cell measurement results and AI unit predictions. In this embodiment, the predicted measurement event may include direct RRM measurement event prediction and indirect RRM measurement event prediction. Direct measurement event prediction can be understood as: the prediction output value of the AI ​​unit, etc., is whether an RRM measurement event will occur within a future period, or the probability of such an event occurring. Indirect measurement event prediction can be understood as: the prediction output of the AI ​​unit, etc., is a future RRM measurement prediction result, and then it is necessary to process the predicted RRM measurement result to determine whether an RRM measurement event will occur at a future point in time.

[0086] One possible implementation is that the predicted measurement event can be configured via an RRM measurement event and a prediction indication. That is, when the RRM measurement event and the prediction indication are associated, the event is considered a predicted measurement event.

[0087] The first cell can be understood as one or more cells among the measurement objects (i.e., the frequency points to be measured). In this embodiment, depending on the first event, the first cell can be a serving cell, a neighboring cell, etc.

[0088] The first cell satisfying the first event can be understood as: the first cell satisfying the entry conditions of the first event within the TTT (Time To Time), wherein the entry conditions of the first event can refer to, but are not limited to, the entry conditions shown in Table 1 above. Wherein, if the first event is a predicted measurement event, then the first cell satisfying the first event can be understood as: the terminal predicts that the first cell will satisfy the entry conditions of the predicted measurement event within a future TTT period.

[0089] S220, when the terminal predicts that a second cell in the first cell will leave the first event, it performs a first operation.

[0090] Understandably, to avoid the inconsistency between the cell quality obtained from RRM measurements and the actual cell quality during handover due to factors such as measurement fluctuations or inaccurate predictions in related technologies, in this embodiment, when the first cell meets the first event, the terminal can further predict whether the first cell will leave the first event to obtain the cell whose cell quality may be inconsistent with the cell quality during handover due to factors such as measurement fluctuations. This avoids the interference of previous RRM measurement reports on handover decisions caused by factors such as cell quality fluctuations, and ensures the performance of the communication system.

[0091] For example, assuming the first event is an RRM measurement event, if the first cell meets the RRM measurement event requirements, a second cell within the first cell may leave the RRM measurement event at some future time (e.g., TTT) due to cell quality fluctuations. Therefore, if the terminal reports RRM measurements based on the RRM measurement reporting process in related technologies, the RRM measurement report will not match the actual cell quality at the time of handover because the first cell includes a second cell that may leave the RRM measurement event. This will affect the accuracy of subsequent handover decisions made by network-side devices based on the terminal's RRM measurement reports. However, this application, by predicting whether the first cell will leave the RRM measurement event, can identify cells whose cell quality at the time of meeting the first event may differ from the actual cell quality at the time of handover due to measurement fluctuations and other factors. This avoids interference from previous RRM measurement reports on handover decisions caused by cell quality fluctuations and other factors, ensuring the performance of the communication system.

[0092] Similarly, assuming the first event is a predicted measurement event, if the first cell meets the predicted measurement event, due to measurement fluctuations, inaccurate predictions, or other reasons, the second cell in the first cell may leave the predicted measurement event at some future time (such as TTT). Based on this, if the terminal performs predicted RRM measurement reporting based on the first cell according to the measurement reporting process in related technologies, the predicted measurement reporting will be inaccurate because the first cell includes a second cell that may leave the predicted measurement event. This will affect the accuracy of the handover decision made by the network-side equipment based on the terminal's predicted RRM measurement reporting. However, by predicting whether the first cell will leave the RRM measurement event, this application can avoid the problem of inconsistent cell quality when the first event is met and cell quality during actual handover caused by measurement fluctuations, inaccurate predictions, and other factors, thus ensuring the performance of the communication system.

[0093] In this embodiment, when the terminal predicts whether the first cell will leave the first event, if it predicts that there is no cell in the first cell that will leave the first event, it can continue to use the RRM measurement reporting process in the related technology to perform measurement reporting; or, if it predicts that there is a second cell in the first cell that will leave the first event, it can execute the first operation described in S220 to store the relevant information of the predicted cell that will leave the first event for subsequent reporting, so as to avoid the problem of inconsistent cell quality when the first event is met and cell quality during actual handover caused by factors such as measurement fluctuations and inaccurate predictions, and ensure the performance of the communication system.

[0094] In this embodiment, the first operation may include, but is not limited to, at least one of the following operations 11-13.

[0095] Operation 11: Store the second cell identifier in a first variable, which is used to store the cell identifiers of the predicted cells that will leave the first event. The cell identifiers stored in the first variable can be represented as a list of cell identifiers.

[0096] In this embodiment, the terminal stores a second cell identifier in a first variable, which is used by the terminal to determine the content of the measurement report based on the first variable and report it to the network-side device. By reporting the predicted cell leaving the first event to the network side, predictive information about the first event is provided to the network, thereby avoiding the problem of inconsistent cell quality at the time of the first event and the actual cell quality during handover caused by factors such as measurement fluctuations and inaccurate predictions, and ensuring the performance of the communication system.

[0097] Optionally, the cell identifier mentioned in Operation 1 and thereafter may include, but is not limited to, Global Cell Identity (GCI), Physical Cell Identity (PCI), Tracking Area Identity (TAI), Public Land Mobile Network Identity (PLMN-ID), etc., without limitation.

[0098] Operation 12: Delete the second cell identifier from the second variable, which stores the cell identifiers of cells that satisfy the first event. The cell identifiers stored in the second variable can be represented as a list of cell identifiers.

[0099] It is understandable that by deleting the second cell identifier from the second variable, the terminal can update the stored list of cell identifiers that meet the first event, so as to determine the cell that stably meets the first event based on the prediction information, thereby avoiding the problem of inconsistent cell quality when the first event is met and cell quality during actual handover caused by factors such as measurement fluctuations and inaccurate predictions, and ensuring the performance of the communication system.

[0100] Operation 13: Store first prediction information in a third variable, the first prediction information being related to the cell that is predicted to leave the first event.

[0101] In this embodiment, the terminal stores the first prediction information in the third variable, which can be used by the terminal to report measurements to the network-side device based on the third variable. This provides the network-side device with predicted values ​​of cell quality and related time information, and provides the network side with more comprehensive prediction information of cells leaving the first event. This avoids the problem of inconsistent cell quality at the time of the first event and the actual cell quality during handover caused by factors such as measurement fluctuations and inaccurate predictions, thus ensuring the performance of the communication system.

[0102] Optionally, the first prediction information may include, but is not limited to, at least one of the following 11)-15).

[0103] 11) A first identifier for identifying the second cell that is predicted to leave the first event.

[0104] It is understandable that if the terminal subsequently reports the first identifier to the network-side device, the network-side device can determine whether to use the second cell indicated by the first identifier as a candidate cell or target cell during cell handover, such as not using the second cell as a candidate cell or target cell during cell handover, in order to avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0105] 12) First indication information, used to indicate at least one cell quality prediction value within a first time period. The first time period can be understood as a prediction window, used to characterize the time during which the first cell is predicted to leave the first event, or to characterize the duration for which the cell quality prediction value of the first cell to be obtained continuously meets the leaving condition of the first event. For example, the terminal predicts whether the first cell will leave the first event within a first time period.

[0106] It is understandable that if the terminal subsequently reports the first indication information to the network-side device, the network-side device can determine whether to use the second cell as a candidate cell or target cell for cell handover based on at least one cell quality prediction value within the first time period indicated by the first indication information. For example, if the at least one cell quality prediction value is less than a third threshold, the second cell can be excluded from the selection of a candidate cell or target cell for cell handover to avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0107] 13) Second indication information, used to indicate the probability that the second cell will leave the first event.

[0108] It is understandable that if the terminal subsequently reports the second indication information to the network-side device, the network-side device can determine whether to use the second cell as a candidate cell or target cell during cell handover based on the probability indicated by the second indication information that the second cell will leave the first event. If the probability is greater than the second threshold, the second cell can be excluded from the selection of a candidate cell or target cell during cell handover to avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0109] 14) Third indication information, used to indicate the predicted time when the second cell will leave the first event.

[0110] It is understandable that if the terminal subsequently reports the third indication information to the network-side device, the network-side device can determine whether to use the second cell as a candidate cell or target cell for cell handover based on the time indicated by the third indication information when the second cell will leave the first event. For example, if the second cell is not used as a candidate cell or target cell for cell handover during the predicted time of the second cell leaving the first event, the network-side device can avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0111] 15) Fourth indication information, used to indicate the cell quality measurement value in the second time period, wherein the second time period is used to characterize the time from the start of predicting whether the first cell will leave the first event to the reporting of the first prediction information.

[0112] It is understandable that if the terminal subsequently reports the fourth indication information to the network-side device, the network-side device can determine whether to use the second cell as a candidate cell or target cell for cell handover based on the cell quality prediction value within the second time period indicated by the fourth indication information. For example, if the cell quality prediction value of at least one cell is less than the fourth threshold, the second cell can be excluded from the selection of a candidate cell or target cell for cell handover, so as to avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0113] It is understood that which of the aforementioned items 11)-15) is actually included in the first prediction information can be determined by protocol agreement or network instruction, and no restriction is made here.

[0114] In this embodiment, when the first cell satisfies the first event, the terminal predicts whether the first cell will leave the first event. When it predicts that a second cell in the first cell will leave the first event, it performs a first operation. The first operation includes one or more of the following: storing the second cell identifier in a first variable, deleting the second cell identifier in a second variable, and storing first prediction information in a third variable. This allows the terminal to predict which cell will leave the first event, thus avoiding the inconsistency between the cell quality when the first event is satisfied and the cell quality during actual handover caused by factors such as measurement fluctuations, and ensuring the performance of the communication system.

[0115] In some embodiments, when the first cell satisfies the first event, a first report may be triggered by the satisfaction of the first event, wherein the first report is associated with the first cell that satisfies the first event. For example, when the first event is an RRM measurement event, the first report can be understood as an RRM measurement report, which may include, but is not limited to, the cell identifier, cell quality measurement value, etc. of the first cell that satisfies the RRM measurement event.

[0116] For example, when the first event is a predicted measurement event, the first report can be understood as a predicted measurement report, or a special type of measurement report, which may include, but is not limited to, the cell identifier of the first cell that satisfies the predicted measurement event, the predicted cell quality measurement value, etc.

[0117] Based on this, in this embodiment, for the scenario where the first report is triggered by the first event, it is possible that the terminal has already sent the first report to the network-side device, or it is possible that the terminal has not yet sent the first report to the network-side device. Therefore, this embodiment will describe the processing methods that the terminal needs to adopt in the following scenarios 1 and 2, depending on whether the first report has been sent or not.

[0118] Scenario 1

[0119] Assuming the first report is triggered by the first event and the terminal has sent the first report to the network-side device, then after performing the first operation, the terminal may send a second report to the network-side device. The second report is related to the predicted event that a second cell in the first cell will leave the first cell. That is, the second report is triggered by the terminal's prediction that a second cell in the first cell will leave the first cell.

[0120] Based on this, it can be understood that after the terminal has sent the first report to the network-side device, the terminal can further send the second report to the network side based on the prediction result, so as to provide the network-side device with information in advance on whether the first cell will leave the first event, that is, to provide the network-side device with prediction information to assist the network-side device in making cell handover strategy decisions, and then issue reasonable mobility configurations to avoid ping-pong handover and ensure the performance of the communication system.

[0121] Optionally, when the terminal sends a second report to the network-side device, it may do so based on a first variable and / or a third variable maintained by the terminal. For example, when sending the second report to the network-side device based on the first variable, the second report may include a second cell identifier stored in the first variable. This allows the network-side device to temporarily disregard considering the second cell as a candidate or target cell during cell handover when making decisions about handover strategies based on the second report, thereby avoiding ping-pong handover and ensuring the performance of the communication system.

[0122] For example, when sending the second report to the network-side device based on the third variable, the second report may include the first prediction information stored in the third variable. This allows the network-side device to refer to the first prediction information (such as the first identifier, first indication information, second indication information, third indication information, and fourth indication information) in the second report when making cell handover strategy decisions based on the second report to determine whether to use the second cell as a candidate cell or target cell for cell handover (see the foregoing description of this pair of first prediction information, which will not be repeated here). For example, the second cell may be temporarily disregarded as a candidate cell or target cell for cell handover, thereby avoiding ping-pong handover and ensuring the performance of the communication system.

[0123] For example, when sending the second report to the network-side device based on the first variable and the third variable, the second report may include the second cell identifier stored in the first variable and the first prediction information.

[0124] Scenario 2

[0125] If the first report is triggered by the first event, but the terminal does not send the first report to the network-side device, then after performing the first operation described in S220, the terminal may perform a second operation. The second operation may include, but is not limited to, at least one of the following operations 21-23.

[0126] Operation 21: Send the first report to the network-side device.

[0127] Operation 22: If it is predicted that there is a second cell in the first cell that will leave the first event, including all cells in the first cell, delete the first report or cancel the transmission of the first report.

[0128] Operation 23: Include the first prediction information in the first report, such as adding, supplementing, or updating the first prediction information in the first report triggered by the first event.

[0129] Regarding the aforementioned operations 21-23, assuming the terminal only executes operation 21, it can be understood that the terminal can send the first report to the network-side device based on the second variable. That is, compared to directly sending the triggered first report to the network-side device after the first event is met, this embodiment sends the first report to the network-side device through operation 21 without including the predicted second cell that will leave the first event. This allows the network-side device to receive an event-triggered first report, such as an RRM measurement report or a predicted measurement report, to assist in making cell handover strategy decisions, thereby issuing reasonable mobility configurations, avoiding ping-pong handover, and ensuring the performance of the communication system.

[0130] Assuming the terminal only performs operation 22, it can be understood that when it is predicted that all cells satisfying the first event will leave the first event, the terminal can delete the first report or cancel the transmission of the first report, thereby avoiding unnecessary reporting of measurement reports or predicted measurement reports, and avoiding ping-pong handover caused by cell handover strategies determined based on inaccurate first reports.

[0131] Assuming the terminal executes operations 21 and 23, it can be understood that the terminal can send the first report to the network-side device based on a third variable. That is, compared to directly sending the triggered first report to the network-side device after the first event is met, this embodiment sends the first report to the network-side device through operations 21 and 23. In this first report, the predicted second cell identifier that will leave the first event is not deleted, and the first report includes the first prediction information. This provides the network-side device with a more reliable measurement report to assist in making cell handover strategy decisions, thereby issuing reasonable mobility configurations, avoiding ping-pong handover, and ensuring the performance of the communication system.

[0132] Alternatively, the terminal's execution of operations 21 and 23 can also be understood as the terminal sending the first report to the network-side device based on the second and third variables. In this first report, the predicted second cell identifier that will leave the first event is deleted; or, the first report deletes both the predicted second cell identifier that will leave the first event and includes the first prediction information. This provides the network-side device with a more reliable measurement report to assist in making cell handover strategy decisions, thereby issuing appropriate mobility configurations, avoiding ping-pong handovers, and ensuring the performance of the communication system.

[0133] In some embodiments, the terminal can predict whether the first cell will leave the first event in the aforementioned S210 in various ways. For example, in this embodiment, the terminal predicting whether the first cell will leave the first event includes: under the condition of satisfying a first condition, the terminal predicts that a second cell in the first cell will leave the first event; wherein, the first condition includes at least one of the following conditions 1-3.

[0134] Condition 1: The cell quality prediction values ​​of the second cell after layer 3 filtering all satisfy the departure condition of the first event within the first time period. Here, the first time period characterizes the time required to predict whether the first cell will leave the first event, or it characterizes the duration for which the cell quality prediction values ​​of the first cell continuously satisfy the departure condition of the first event. The first time period can be TTT, etc.

[0135] Condition 2: The probability that the second cell will leave the first event within a first time period is not less than a first threshold. Here, the first time period characterizes the time required to predict whether the first cell will leave the first event, or it characterizes the duration for which the predicted cell quality value of the first cell continuously meets the leaving condition of the first event. The first time period can be TTT, etc.

[0136] Condition 3: Within a third time period (e.g., TTT) after the cell quality of the second cell after layer 3 filtering meets the departure condition of the first event, the predicted value of the cell quality of the second cell after layer 3 filtering meets the departure condition of the first event continues to meet the departure condition of the first event. The third time period characterizes the time during which the predicted value of the cell quality of the second cell after layer 3 filtering meets the departure condition of the first event must continue to meet the departure condition of the first event.

[0137] Specifically, the statement that the cell quality of the second cell after layer 3 filtering in condition 3 satisfies the "cell quality of the second cell after layer 3 filtering" in the departure condition of the first event can be understood as follows: if the first event is an RRM measurement event, then the cell quality of the second cell after layer 3 filtering is the cell quality measurement value; if the first event is a prediction measurement event, then the cell quality of the second cell after layer 3 filtering is the cell quality prediction value.

[0138] In this embodiment, the first time and the third time can be the same, for example, both can be TTT as described above, or they can be different, and there is no limitation here.

[0139] Optionally, the departure conditions for the first event mentioned in this embodiment may include, but are not limited to, the departure conditions described in Table 1 above.

[0140] In some embodiments, the method embodiment 200 may further include: the terminal obtaining first configuration information, wherein the first configuration information is used to configure relevant information when the terminal makes a prediction of whether the first cell will leave the first event, thereby ensuring that the terminal and the network-side device have a consistent understanding of the relevant information when the terminal makes a prediction of whether the first cell will leave the first event.

[0141] Optionally, the terminal can obtain the first configuration information in various ways. For example, the terminal can obtain the first configuration information agreed upon by the protocol, or it can obtain the first configuration information from a network-side device. No limitation is made here. Specifically, in the case where the terminal obtains the first configuration information from a network-side device, the network-side device can send the first configuration information to the terminal as part of the measurement configuration, etc., without restriction.

[0142] Optionally, the first configuration information may include, but is not limited to, at least one of the following first information and second information. The first information is used to instruct the terminal to predict whether the first cell will leave the first event when the second condition is met.

[0143] Optionally, the satisfaction of the second condition may include, but is not limited to, any one of the following 21)-22).

[0144] 21) The first event is satisfied.

[0145] 21) The first event is satisfied, and the departure condition of the first event is also satisfied.

[0146] The second information is used to instruct the terminal on relevant parameters or information involved in predicting whether the first cell will leave the first event. Optionally, the second information may include, but is not limited to, at least one of the following 31)-36).

[0147] 31) First time, the first time is used to characterize the time when it is predicted whether the first cell will leave the first event, or the first time is used to characterize the duration for which the predicted cell quality value of the first cell to be obtained continuously meets the leaving condition of the first event.

[0148] 32) The second time is used to characterize the time from the start of predicting whether the first cell will leave the first event to the reporting of the first prediction information.

[0149] 33) The third time is used to characterize the time during which the predicted value of the cell quality after the layer 3 filtering of the second cell meets the departure condition of the first event.

[0150] 34) A first threshold is used to indicate the probability threshold for predicting whether the first cell will leave the first event.

[0151] 35) Fifth instruction information, used to instruct the terminal to report that it will leave the cell of the first event.

[0152] 36) A sixth instruction message, used to instruct the terminal to report a third report, the third report being related to the cell from which the first event occurred. The third report may be either the first report or the second report mentioned above.

[0153] In some embodiments, the terminal can predict whether the first cell will leave the first event using various methods described in the foregoing embodiments. For example, the terminal can predict whether the first cell will leave the first event based on an AI unit. For instance, if the first event meets the conditions for entry within the first event time frame (TTT), the terminal initiates predictive inference based on the AI ​​unit to predict whether the first cell will leave the first event.

[0154] In this embodiment, after the first cell satisfies the first event, the AI ​​unit is further used to predict whether the first cell will leave the first event, which can improve the prediction efficiency and ensure the reliability of the prediction results.

[0155] In some embodiments, for the first event mentioned in the foregoing embodiments, as shown in FIG3a and FIG3b, the RRM measurement event and the predicted measurement event may satisfy, but are not limited to, any one of the following 41)-44).

[0156] 41) The RRM measurement event and the predicted measurement event are associated with (or share) the same measurement identifier, and the RRM measurement event and the predicted measurement event are associated with the same reporting variable.

[0157] Optionally, if the RRM measurement event and the predicted measurement event are associated with the same measurement identifier and the RRM measurement event and the predicted measurement event are associated with the same reporting variable, at least one of the following a)-c) is satisfied.

[0158] a) The RRM measurement event and the predicted measurement event are configured in the measurement configuration associated with the same measurement identifier.

[0159] b) The third and fourth cells are stored in the first cell list, such as celltriggeredlist. The third cell satisfies the entry condition for the measurement event, and the fourth cell satisfies the entry condition for the predicted measurement event.

[0160] Optionally, considering that the cell that satisfies the RRM measurement event and the predicted measurement event is the same cell, a separate cell category, celltriggerlistPred, can be introduced or configured to store the cell identifiers of the cells that satisfy the predicted measurement event separately.

[0161] c) The first report corresponding to the measurement event and the first report corresponding to the predicted measurement event are both stored in the measurement report list variable, such as VarMeasReportList.

[0162] For example, assuming that the first configuration information is associated with the first measurement configuration identifier, and the first measurement configuration identifier corresponds one-to-one with the first measurement identifier, then the terminal only maintains a measurement report list variable for the first measurement identifier. That is, the first report that meets the first event trigger does not distinguish whether it is triggered by the RRM measurement event or by the predicted measurement event.

[0163] Specifically, for the first measurement identifier, i.e., the same measurement identifier associated with the RRM measurement event and the predicted measurement event, if the measurement report corresponding to the first measurement identifier is configured as an event-triggered report, and the second cell among the first cells that satisfy the first event included in the measurement report entry corresponding to the first measurement identifier in the measurement report list variable satisfies the first condition, then the terminal may perform at least one of the following operations: 31-33. The first condition will not be elaborated upon here.

[0164] Operation 31: If the first configuration information includes the fifth indication information, then the predicted second cell that will leave the first event is stored in the leaving cell variable of the measurement report entry corresponding to the first measurement identifier in the first variable.

[0165] Operation 32: Delete the second cell from the first cell that satisfies the first event from the first variable; or store first prediction information in the third variable, the first prediction information being related to the cell that is predicted to leave the first event;

[0166] Operation 32: If the first measurement configuration includes the sixth indication information, the first report or the second report can be reported according to the measurement reporting process corresponding to the first measurement identifier. The first report or the second report can be referred to the foregoing description, and will not be repeated here.

[0167] 42) The RRM measurement event and the predicted measurement event are associated with the same reporting variable, and the RRM measurement event and the predicted measurement event are associated with different measurement identifiers.

[0168] Optionally, when the RRM measurement event and the predicted measurement event are associated with the same reporting variable, and the measurement event and the predicted measurement event are associated with different measurement identifiers, the first report corresponding to the measurement event and the first report corresponding to the predicted measurement event are both stored in a measurement report list variable, such as VarMeasReportList, but the measurement event and the predicted measurement event correspond to different measurement report entries.

[0169] For example, assuming that the first configuration information corresponding to the RRM measurement event is associated with a first measurement configuration identifier, and the first configuration information corresponding to the predicted measurement event is associated with a second measurement configuration identifier, and that the first measurement configuration identifier corresponds one-to-one with the first measurement identifier and the second measurement configuration identifier corresponds one-to-one with the second measurement identifier, the terminal maintains a measurement report list variable for both the first and second measurement identifiers (the event-triggered measurement report is distinguished between being triggered by the RRM measurement event and being triggered by the predicted measurement event). The terminal-side behavior can be described with reference to the example in 41) above, but unlike 41), the network-side device will impose restrictions, such as preventing the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event from appearing simultaneously under the same measurement configuration identifier.

[0170] 43) The RRM measurement event and the predicted measurement event are associated with the same measurement identifier. The RRM measurement event and the predicted measurement event are associated with different reporting variables, such as the RRM measurement event being associated with the measurement report list variable VarMeasReportList, and the predicted measurement event being associated with the prediction report list variable VarPredReportList.

[0171] Optionally, when the RRM measurement event and the predicted measurement event are associated with the same measurement identifier, and the RRM measurement event and the predicted measurement event are associated with different reporting variables, the first report corresponding to the measurement event is stored in a measurement report list, such as VarMeasReportList, and the first report corresponding to the predicted measurement event is stored in a prediction report list, such as VarPredReportList.

[0172] For example, assuming that the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event are both associated with the first measurement configuration identifier, and the first measurement configuration identifier corresponds one-to-one with the first measurement identifier (i.e., the same measurement identifier), then the terminal can maintain a measurement report list variable and a prediction report list variable for the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event, respectively. The measurement report list variable corresponds to the predicted departure of the RRM measurement event, and the prediction report list variable corresponds to the predicted departure of the predicted measurement event.

[0173] Based on this, for the first measurement identifier, if the measurement report corresponding to the first measurement identifier is configured as an event-triggered report, and the second cell in the first cell that satisfies the event in the measurement report entry corresponding to the first measurement identifier in the measurement report list variable satisfies the first condition, then the terminal may perform at least one of the following operations: 41-44.

[0174] Operation 41: If the first measurement configuration includes first configuration information corresponding to the RRM measurement event, and the first configuration information includes fifth indication information, then the second cell can be stored in the leaving cell variable of the measurement report entry corresponding to the first measurement identifier in the first variable; and / or, the second cell in the first cell that satisfies the RRM measurement event is deleted.

[0175] Operation 42: If the first measurement configuration includes the first configuration information corresponding to the RRM measurement event, and the first configuration information includes the sixth indication information, then the measurement reporting process corresponding to the first measurement identifier is triggered to report the first report or the second report. The first report or the second report can be referred to the foregoing description, and will not be repeated here.

[0176] Operation 43: If the first measurement configuration includes first configuration information corresponding to the predicted measurement event, and the first configuration information includes fifth indication information, then the second cell can be stored in the leaving cell variable of the prediction report entry corresponding to the first measurement identifier in the second variable; and / or, the second cell in the first cell that satisfies the predicted measurement event is deleted.

[0177] Operation 44: If the first measurement configuration includes first configuration information corresponding to the predicted measurement event, and the first configuration information includes sixth indication information, then the measurement reporting process corresponding to the first measurement identifier can be triggered to report the first report or the second report. The first report or the second report can be referred to the foregoing description, and will not be repeated here.

[0178] If the measurement reporting corresponding to the first measurement identifier is configured to be triggered by a predicted measurement event, and one or more applicable cells meet the predicted measurement event, then a prediction report entry corresponding to the first measurement identifier is generated in the second variable, and the first cell that is predicted to meet the predicted measurement event is included in the entry, and the prediction reporting process corresponding to the first measurement identifier is triggered.

[0179] The following can be included for one or more applicable cells to satisfy the predicted measurement event: the L3 filtered cell quality prediction values ​​of one or more applicable cells all satisfy the entry condition of the first event within a fourth time (such as TTT), and / or, one or more applicable cells are predicted to possibly satisfy the first event within a fifth time (i.e., the probability of the predicted measurement event being satisfied is not less than a first threshold).

[0180] 44) The RRM measurement event and the predicted measurement event are associated with different measurement identifiers and different reporting variables, respectively.

[0181] Optionally, when the RRM measurement event and the predicted measurement event are associated with different measurement identifiers and different reporting variables, the first report corresponding to the measurement event is stored in a measurement report list, such as VarMeasReportList, and the first report corresponding to the predicted measurement event is stored in a prediction report list, VarPredReportList.

[0182] For example, assuming that the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event are both associated with the first measurement configuration identifier, and the first measurement configuration identifier corresponds one-to-one with the first measurement identifier (i.e., the same measurement identifier), then the terminal can maintain a measurement report list variable and a prediction report list variable for the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event, respectively. The measurement report list variable corresponds to the predicted departure of the RRM measurement event, and the prediction report list variable corresponds to the predicted departure of the predicted measurement event.

[0183] Based on this, for the first measurement identifier, if the measurement report corresponding to the first measurement identifier is configured as an event-triggered report, and the second cell among the first cells that satisfy the event included in the measurement report entry corresponding to the first measurement identifier in the measurement report list variable satisfies the first condition, then the terminal may perform at least one of the following operations 51-53. The first condition will not be elaborated upon here.

[0184] Operation 51: If the first configuration information includes the fifth indication information, then the predicted second cell that will leave the first event is stored in the leaving cell variable of the measurement report entry corresponding to the first measurement identifier in the first variable.

[0185] Operation 52: Delete the second cell from the first cell that satisfies the first event from the first variable; or store first prediction information in the third variable, the first prediction information being related to the cell that is predicted to leave the first event;

[0186] Operation 52: If the first measurement configuration includes the sixth indication information, the first report or the second report can be reported according to the measurement reporting process corresponding to the first measurement identifier. The first report or the second report can be referred to the above description, and will not be repeated here.

[0187] It should be noted that for the RRM measurement event and the predicted measurement event described in 44) which are associated with different measurement identifiers and different reporting variables, the network side will impose restrictions, such as restricting the first configuration information corresponding to the RRM measurement event and the first configuration information corresponding to the predicted measurement event from appearing simultaneously under the same measurement configuration identifier.

[0188] In some embodiments, the list of prediction reports in 43)-44) may further include historical measurement results used to predict whether the first cell will leave the predicted measurement event.

[0189] Based on the description of the communication method in the aforementioned method embodiment 200, in order to better understand the technical solution of this application, the implementation process of the communication method provided by this application is described in illustrative form below with reference to examples.

[0190] Example 1

[0191] Assuming the first event is an RRM measurement event, then, as shown in Figure 4a, the communication process provided in this embodiment can be as follows.

[0192] S410, the network-side device (such as a base station) sends the first configuration information to the terminal.

[0193] The first configuration information is used to configure relevant information when the terminal makes a prediction about whether the first cell will leave the first measurement event.

[0194] The first configuration information includes at least one of the following a)-g).

[0195] a) First information, used to instruct the terminal to predict whether the first cell will leave the RRM measurement event when the second condition is met.

[0196] The second condition includes any one of the following a1)-a2).

[0197] a1) Satisfies the RRM measurement event.

[0198] a2) The RRM measurement event is satisfied, and the departure condition of the RRM measurement event is also satisfied.

[0199] b) First time, the first time is used to characterize the time when the prediction of whether the first cell will leave the RRM measurement event, or to characterize the duration for which the cell quality prediction value of the first cell to be obtained continuously meets the leaving condition of the first event.

[0200] c) A second time, used to characterize the time from the start of predicting whether the first cell will leave the RRM measurement event to the reporting of the first prediction information.

[0201] d) The third time is used to characterize the time during which the predicted value of the cell quality after the layer 3 filtering of the second cell meets the departure condition of the first event.

[0202] e) A first threshold, used to indicate the probability threshold for predicting whether the first cell will leave the RRM measurement event.

[0203] f) Fifth instruction information, used to instruct the terminal to report the cell where it will leave the RRM measurement event.

[0204] g) A sixth instruction message, used to instruct the terminal to report a third report, the third report being related to the cell that will leave the RRM measurement event.

[0205] S420, the terminal performs measurements according to the measurement configuration, and determines the first cell that meets the RRM measurement event based on the measurement results.

[0206] S430, the terminal predicts whether the first cell will leave the RRM measurement event based on the first configuration information and the AI ​​unit, and maintains at least one of the first variable, the second variable, and the third variable.

[0207] The implementation process in S430 can be shown in Figure 4b, as follows.

[0208] S4301, the terminal predicts whether the first cell will leave the RRM measurement event based on the first configuration information and the AI ​​unit. If it predicts that there is a second cell in the first cell that will leave the RRM measurement event, then S4302 is executed. Otherwise, the RRM measurement reporting can be performed according to the RRM measurement reporting process provided in the related technology.

[0209] S4302, the terminal determines whether the first configuration information includes the fifth indication information (used to instruct the terminal to report the cell that will leave the RRM measurement event). If it includes it, then execute S4303; otherwise, execute S4304.

[0210] S4303, a second cell identifier is stored in a first variable, the first variable being used to store the cell identifier of the predicted cell that will leave the RRM measurement event, and / or, first prediction information is stored in a third variable, the first prediction information being related to the cell that is predicted to leave the RRM measurement event.

[0211] S4304, delete the second cell identifier from the second variable, which is used to store the cell identifier of the cell that satisfies the RRM measurement event.

[0212] S440, the terminal determines whether the first configuration information includes sixth indication information (used to instruct the terminal to report a third report, the third report being related to the cell that will leave the RRM measurement event). If it includes it, then execute S450 or S460.

[0213] S450, when the measurement report (or RRM measurement report) is triggered by an RRM measurement event and the measurement report has been sent by the terminal to the network-side device, the terminal sends a second report to the network-side device according to the first variable or the third variable in S430. The second report is related to the predicted RRM measurement event that a second cell in the first cell will leave the first cell, such as the second report including the first prediction information.

[0214] Optionally, the first prediction information may include, but is not limited to, at least one of the following a)-e).

[0215] a) A first identifier for identifying the second cell that is predicted to leave the RRM measurement event.

[0216] b) First indication information, used to indicate at least one cell quality prediction value within a first time period, the first time period can be understood as a prediction window, used to characterize the time for predicting whether the first cell will leave the RRM measurement event, or used to characterize the duration for which the cell quality prediction value of the first cell to be obtained continuously meets the leaving condition of the first event.

[0217] c) Second indication information, used to indicate the probability that the second cell will leave the RRM measurement event.

[0218] d) Third indication information, used to indicate the predicted time when the second cell will leave the RRM measurement event.

[0219] e) Fourth indication information, used to indicate cell quality measurement values ​​within a second time period, wherein the second time period is used to characterize the time from the start of predicting whether the first cell will leave the RRM measurement event to the reporting of the first prediction information.

[0220] S460, if the measurement report (or RRM measurement report) is triggered by an RRM measurement event but the measurement report is not sent by the terminal to the network-side device, the terminal performs a second operation based on the second variable and / or the third variable in S430.

[0221] The second operation includes at least one of the following operations 21-23.

[0222] Operation 21: Send the first report to the network-side device.

[0223] Operation 22: If it is predicted that there is a second cell in the first cell that will leave the RRM measurement event, including all cells in the first cell, delete the first report or cancel the transmission of the first report.

[0224] Operation 23: Include the first prediction information in the first report.

[0225] S470, the network-side device determines the handover strategy based on the first or second report received.

[0226] The prediction start time and reporting time for predicting whether the first cell will leave the RRM measurement time are explained below with reference to Figures 4c and 4d.

[0227] As shown in Figure 4c, assuming that the first cell meets the entry conditions of the RRM measurement event at time T1, and at time T2, one TTT interval after time T1, the terminal begins to predict whether the first cell will leave the RRM measurement event within the first time (e.g., TTT). At the same time, at time T2, the RRM measurement event triggers the first report (i.e., measurement report), and / or, the prediction event of whether the first cell will leave the RRM measurement event triggers the reporting of the first report or the second report.

[0228] As shown in Figure 4d, assuming that the first cell meets the entry conditions for the RRM measurement event at time T1, and at time T2, one TTT interval after time T1, the terminal determines that the first cell meets the RRM measurement event, and the RRM measurement event triggers the first report (i.e., measurement report); at time T3, one predetermined time interval after time T2, the terminal begins to predict whether the first cell will leave the RRM measurement event within the first time (e.g., TTT), and at the same time, at time T3, the terminal's prediction of whether the first cell will leave the RRM measurement event triggers the reporting of the second report.

[0229] In Example 1, when the first cell meets the RRM measurement event, the terminal predicts whether the first cell will leave the RRM measurement event, thereby providing prior information to the network-side equipment to assist the network in optimizing the handover configuration, avoiding ping-pong handover, and ensuring the performance of the communication system.

[0230] It is understood that the implementation process of each step in this Example 1 can refer to the relevant description in the aforementioned method embodiment 200, and will not be repeated here to avoid repetition. In addition, the implementation process of this Example 1 may include, but is not limited to, the aforementioned steps, such as including more or fewer steps than those in S410-S470, which is not limited here.

[0231] Example 2

[0232] Assuming the first event is a predicted measurement event, that is, an RRM measurement event that may occur based on the cell measurement results and the AI ​​unit prediction, then, as shown in Figure 5a, the communication process provided in this embodiment can be as follows.

[0233] S510, the network-side device (such as a base station) sends the first configuration information to the terminal.

[0234] The first configuration information is used to configure relevant information when the terminal makes a prediction about whether the first cell will leave the first measurement event.

[0235] The first configuration information includes at least one of the following a)-g).

[0236] a) First information, used to instruct the terminal to predict whether the first cell will leave the predicted measurement event when the second condition is met.

[0237] The second condition includes any one of the following a1)-a2).

[0238] a1) satisfies the predicted measurement event.

[0239] a2) The predicted measurement event is satisfied, and the departure condition of the predicted measurement event is also satisfied.

[0240] b) First time, the first time is used to characterize the time when it is predicted whether the first cell will leave the predicted measurement event, or to characterize the duration for which the cell quality prediction value of the first cell to be obtained continuously meets the leaving condition of the first event.

[0241] c) A second time, used to characterize the time from the start of predicting whether the first cell will leave the predicted measurement event to the reporting of the first prediction information.

[0242] d) The third time is used to characterize the time during which the predicted value of the cell quality after the layer 3 filtering of the second cell meets the departure condition of the first event.

[0243] e) A first threshold, used to indicate the probability threshold for predicting whether the first cell will leave the predicted measurement event.

[0244] f) Fifth indication information, used to instruct the terminal to report the cell where it will leave the predicted measurement event.

[0245] g) A sixth instruction message, used to instruct the terminal to report a third report, the third report being related to the cell that will leave the predicted measurement event.

[0246] S520, the terminal performs measurements according to the measurement configuration, and determines that the first cell meets the first measurement event based on the measurement results.

[0247] S530, the terminal predicts whether the first cell will leave the predicted measurement event based on the first configuration information and the AI ​​unit, and maintains at least one of the first variable, the second variable, and the third variable.

[0248] For example, the implementation process in S530 can be shown in Figure 5b, as follows.

[0249] S5301, the terminal predicts whether the first cell will leave the predicted measurement event based on the first configuration information and the AI ​​unit. If it is predicted that there is a second cell in the first cell that will leave the predicted measurement event, then S5302 is executed. Otherwise, RRM measurement reporting can be performed according to the RRM measurement reporting process provided in related technologies.

[0250] S5302, the terminal determines whether the first configuration information includes the fifth indication information (used to instruct the terminal to report the cell that will leave the predicted measurement event). If it includes it, then S5304 is executed; otherwise, S5304 is executed.

[0251] S5303, a second cell identifier is stored in a first variable, the first variable being used to store the cell identifier of the predicted cell that will leave the predicted measurement event, and / or, a first prediction information is stored in a third variable, the first prediction information being related to the cell that is predicted to leave the predicted measurement event.

[0252] S5304, delete the second cell identifier from the second variable, which is used to store the cell identifier of the cell that satisfies the predicted measurement event.

[0253] S540, the terminal determines whether the first configuration information includes sixth indication information (used to instruct the terminal to report a third report, the third report being related to the cell that will leave the predicted measurement event). If it does, then S550 or S560 is executed.

[0254] S550, when the measurement report (or predicted measurement report) is triggered by a predicted measurement event and the measurement report has been sent by the terminal to the network-side device, the terminal sends a second report to the network-side device according to the first variable or the third variable in S540. The second report is related to the predicted measurement event that a second cell in the first cell will leave the predicted measurement event, such as the second report including first prediction information.

[0255] Optionally, the first prediction information may include, but is not limited to, at least one of the following a)-e).

[0256] a) A first identifier for identifying the second cell that is predicted to leave the predicted measurement event.

[0257] b) First indication information, used to indicate at least one cell quality prediction value within a first time period, the first time period can be understood as a prediction window, used to characterize the time during which the first cell is predicted to leave the predicted measurement event, or used to characterize the duration for which the cell quality prediction value of the first cell to be obtained continuously meets the leaving condition of the first event.

[0258] c) Second indication information, used to indicate the probability that the second cell will leave the predicted measurement event.

[0259] d) Third indication information, used to indicate the time when the second cell is predicted to leave the predicted measurement event.

[0260] e) Fourth indication information, used to indicate cell quality measurement values ​​within a second time period, wherein the second time period is used to characterize the time from the start of predicting whether the first cell will leave the predicted measurement event to the reporting of the first prediction information.

[0261] The implementation of S550 can provide prior information for network-side devices to determine handover strategies in a timely manner, avoiding unnecessary handovers due to incorrect predictions.

[0262] S560, if the measurement report (or predicted measurement report) is triggered by a predicted measurement event but the measurement report is not sent by the terminal to the network-side device, the terminal performs a second operation based on the second or third variable in S530.

[0263] The second operation includes at least one of the following operations 21-23.

[0264] Operation 21: Send the first report to the network-side device.

[0265] Operation 22: If it is predicted that there is a second cell in the first cell that will leave the predicted measurement event, including all cells in the first cell, delete the first report or cancel the transmission of the first report.

[0266] Operation 23: Include the first prediction information in the first report.

[0267] By implementing operations 21 and / or 23 in S550, prior information can be provided to network-side devices to determine handover strategies in a timely manner, avoiding unnecessary handovers due to incorrect predictions. Alternatively, by implementing operation 22 in S550, unnecessary prediction measurement reports (such as the first report of deletion or cancellation) can be avoided, thus preventing ping-pong handovers.

[0268] S570: The network-side device determines the handover strategy based on the first or second report received.

[0269] It is worth noting that, regarding the prediction start time and reporting time for predicting whether the first cell will leave the RRM measurement time, assuming the predicted measurement event (i.e., the RRM measurement event that may occur based on the cell measurement results and the AI ​​unit prediction) is Prediction 1, and the prediction of whether the first cell that satisfies the predicted measurement event will leave the predicted measurement event at the first time is Prediction 2, then, as shown in Figure 5c, at time T1, Prediction 1 and Prediction 2 begin, and Prediction 1 triggers the reporting of the predicted measurement report, while Prediction 2 predicts whether the first cell will leave the predicted measurement time at the first time. Furthermore, the time when Prediction 2 triggers the reporting of the predicted measurement report (such as the aforementioned second report) cannot be later than time T2, to avoid the network-side equipment receiving the report triggered by Prediction 2 only after completing the handover decision.

[0270] Furthermore, in Figure 5c, the time period from the start of prediction 2 to the latest prediction 2 triggering measurement reporting is defined as the second time (T2-T1). This is understandable because indirect event predictions need to be based on historical measurements. That is, when the terminal predicts whether to leave the predicted measurement event (within the first time after the prediction satisfies the predicted measurement event), it needs to consider historical measurement results prior to the current time point. The second time specifies the most recent historical measurement time point information that can be referenced.

[0271] As shown in Figure 5d, the prediction windows of prediction 2 and prediction 1 overlap, meaning that prediction 1 and prediction 2 start simultaneously at time T1.

[0272] In Example 2, when the predicted measurement event is met in the first cell, the terminal provides prior information to the network-side equipment by predicting whether the first cell will leave the predicted measurement event. This information is used to assist the network in optimizing the handover configuration, avoiding ping-pong handover, and ensuring the performance of the communication system.

[0273] It is understood that the implementation process of each step in this Example 2 can refer to the relevant description in the aforementioned Method Embodiment 200. To avoid repetition, it will not be repeated here. In addition, the implementation process of this Example 2 may include, but is not limited to, the aforementioned steps. For example, it may include more or fewer steps than the aforementioned S510-S570, which is not limited here.

[0274] Figure 6 shows a flowchart of a communication method 600 provided in an exemplary embodiment of this application. This method 600 can be executed by, but is not limited to, a network-side device, specifically by hardware and / or software installed in the network-side device. In this embodiment, the method 600 may include at least the following steps.

[0275] S610: In the case that the first event is satisfied in the first cell, the network-side device receives the third information from the terminal.

[0282] In some embodiments, the second information includes at least one of the following: a first time, which characterizes the time at which the predicted first cell will leave the first event, or the duration for which the predicted cell quality value of the first cell needs to continuously meet the departure condition of the first event; a second time, which characterizes the time from the start of predicting whether the first cell will leave the first event to the reporting of the first prediction information; a third time, which characterizes the time for which the predicted cell quality value of the second cell after the layer 3 filtering meets the departure condition of the first event, and the predicted cell quality value of the second cell needs to continuously meet the departure condition of the first event; a first threshold, which indicates the probability threshold for predicting whether the first cell will leave the first event; a fifth indication information, which instructs the terminal to report cells that will leave the first event; and a sixth indication information, which instructs the terminal to report a third report, the third report being related to cells that will leave the first event.

[0283] In some embodiments, the first event includes at least one of the following: a radio resource management (RRM) measurement event; and a predicted measurement event, characterized by RRM measurement events that may occur based on cell measurement results and AI unit predictions.

[0284] In some embodiments, the method further includes: the network-side device determining a cell handover strategy based on the third information. For example, the network-side device may determine whether to use the second cell indicated by the first identifier as a candidate cell or target cell during cell handover based on the third information. For instance, the second cell that is predicted to leave the first event may not be used as a candidate cell or target cell during cell handover, in order to avoid problems such as ping-pong handover caused by the second cell leaving the first event.

[0285] It is understood that each implementation in this method embodiment 600 has the same or corresponding technical features as the aforementioned method embodiment 200. Therefore, the implementation of each implementation in this method embodiment 600 can be referred to the relevant description in the aforementioned method embodiment 200 to achieve the same or corresponding technical effects. To avoid repetition, it will not be described again here.
