[0033] The embodiments of the present disclosure provide a communication method, a terminal, a network device, and a storage medium.

[0034] In a first aspect, an embodiment of the present disclosure proposes a communication method, which includes: a terminal predicts a first moment and a second moment based on an artificial intelligence AI model, wherein the first moment and the second moment are used to predict the cell residence time ToS of the terminal in the first cell after switching from the serving cell to the first cell.

[0035] In the above embodiment, by predicting the time when the terminal's measurement results from the serving cell and / or the measurement results of the first cell meet the reporting conditions based on the AI ​​model, and predicting the time when the measurement results of the first cell and / or the measurement results of the second cell meet the reporting conditions, the two predicted times can be used to predict the ToS of the terminal in the first cell, so that it can be determined whether the terminal should be handed over from the serving cell to the first cell based on the ToS. This avoids problems such as signaling consumption and terminal-network connection interruption caused by frequent handovers of the terminal.

[0036] In some optional embodiments of the first aspect, the first moment indicates a moment when a first measurement result satisfies a reporting event, and the first measurement result is used for the terminal to switch from the serving cell to the first cell; or, the first moment indicates a moment when the terminal starts to switch from the serving cell to the first cell; or, the first moment indicates a moment when the terminal successfully switches from the serving cell to the first cell; or, the first moment indicates a moment when the terminal sends a switching completion message to the first cell.

[0037] In the above embodiment, the first moment predicted by the terminal can be the moment when the first measurement result meets the reporting condition, the moment when the serving cell starts to switch to the first cell, the moment when the switching from the serving cell to the first cell is successful, or the moment when the terminal sends a switching completion message to the first cell, so as to flexibly predict the first moment and more efficiently obtain the first moment for pre-storing ToS.

[0039] In the above embodiment, the second moment predicted by the terminal can be the moment when the second measurement result meets the reporting condition, the moment when the first cell starts to switch to the second cell, the moment when the handover from the first cell to the second cell is successful, or the moment when the terminal sends a handover completion message to the second cell, so as to flexibly predict the second moment and more efficiently obtain the second moment for pre-storing ToS.

Alternatively, the terminal may send the difference between the first moment and the second moment to the network device so that the network device can directly determine the difference as the ToS while ignoring the error, or calculate the ToS, thereby achieving more reasonable cell switching and avoiding problems such as signaling consumption and connection interruption caused by frequent switching.

[0138] In some embodiments, obtaining data, information, etc. may comply with the laws and regulations of the country where the data is obtained.

[0139] In some embodiments, data, information, etc. may be obtained with the user's consent.

[0140] In addition, each element, each row, or each column in the table of the embodiment of the present disclosure can be implemented as an independent embodiment, and the combination of any elements, any rows, and any columns can also be implemented as an independent embodiment.

[0141] Currently, when the terminal discovers a condition that meets the network configuration, i.e., an event, the terminal reports the measurement result for cell handover. Take event A3 as an example. Event A3 means that after considering various offsets, the neighboring cell is better than the serving cell. The serving cell can include the Primary Cell (PCell) and the Primary Secondary Cell (PSCell), simply referred to as the SpCell. The entering condition of event A3 is: Mn + Ofn + Ocn – Hys > Mp + Ofp + Ocp + Off, and the leaving condition is: Mn + Ofn + Ocn + Hys < Mp + Ofp + Ocp + Off. Here, Mn is the measurement result of the neighboring cell, and Mp is the measurement result of the SpCell. Ofn and Ocn are the offsets of the neighboring cell, Ofp and Ocp are the offsets of the SpCell, Off is the offset configured for event A3, and Hys is the hysteresis of event A3. When the UE discovers that the duration for which the measurement result meets the entering condition reaches the configured time trigger (timeToTrigger), the UE will report the corresponding measurement result. The UE reports the measurement result using a Radio Resource Control (RRC) message, MeasurementReport. The network may initiate a handover process based on the received UE measurement result. For example, when event A3 is triggered, the current serving gNB of the UE, i.e., the source gNB, sends a handover request to the target gNB corresponding to the appropriate neighboring cell.

[0142] The Time of Stay (ToS) of the terminal in a cell is an indicator for measuring handover performance. If the ToS is too short, it means frequent handovers, which will cause a large amount of signaling overhead and connection interruptions and need to be avoided. The ToS can be the time between two handovers.

[0143] Therefore, the present disclosure provides a communication method. By predicting, based on an AI model, the moment when the terminal starts to handover from the serving cell to the first cell and the moment when the terminal starts to handover from the first cell to the second cell, the two predicted moments can be used to determine the ToS, so as to be able to determine whether the terminal handovers from the serving cell to the first cell according to the ToS. This can avoid problems such as signaling consumption and interruption of the connection between the terminal and the network caused by frequent handovers of the terminal.

[0144] In some embodiments, the network configures the UE to perform measurements. The measurement configuration includes the following parameters:

[0145] 1. Measurement object: A list of objects that the UE measures. For intra-frequency and inter-frequency measurements, the measurement object indicates the time and frequency location of the reference signal and the subcarrier spacing.

[0146] 2. Reporting configuration includes reporting criteria, reference signal type and reporting format. The reporting criteria refers to the criteria that triggers the UE to send measurement reports, which can be periodic or event-driven.

[0147] 3. The measurement identity links the measurement object with the reporting configuration.

[0148] 4. The quantity configuration defines the measurement filter configuration.

[0149] 5. A measurement gap is a time period reserved by the UE for measurement, during which the UE does not send or receive data.

[0150] In some embodiments, the inter-gNB handover process is shown in Figure 1a below:

[0151] 1. The source gNB initiates a handover and sends a HANDOVER REQUEST message via the Xn interface.

[0152] 2. The target gNB performs admission control and includes an RRC Reconfiguration message in the HANDOVER REQUEST ACKNOWLEDGE message to provide target cell configuration information. This configuration information may include bearer configuration, media access control (MAC) configuration, and random access configuration.

[0153] 3. The source gNB forwards the RRCReconfiguration message in the HANDOVER REQUEST ACKNOWLEDGE message to the UE.

[0154] 4. The UE synchronizes with the target cell, initiates a random access procedure to access the target cell, starts using the carried target cell configuration, and responds with an RRC Reconfiguration Complete message.

[0155] In some embodiments, machine learning algorithms are one of the most important implementations of artificial intelligence (AI) technology. Machine learning can generate models from large amounts of training data, which can then be used to predict events. In many fields, models trained using machine learning can produce highly accurate predictions.

[0167] FIG2a is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2a , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0168] Step S2101 , the network device 102 sends first information to the terminal 101 .

[0169] In some embodiments, the terminal 101 receives first information sent by the network device 102 .

[0170] In some embodiments, the first information is used to instruct the terminal to predict the first and second moments based on the AI ​​model. The terminal can predict the ToS based on the AI ​​model based on the first information. The first and second moments are used to predict the ToS, that is, the network device can also instruct the terminal to predict the ToS based on the AI ​​model through the first information. The terminal can predict the first and second moments and predict the ToS based on the first and second moments. Of course, the terminal can also send the first and second moments to the network device, and the network device can predict the ToS based on the first and second moments.

[0171] In some embodiments, the first moment indicates the moment when the first measurement result meets the reporting event, and the first measurement result is used to switch the terminal from the serving cell to the first cell; or, the first moment indicates the moment when the terminal starts to switch from the serving cell to the first cell; or, the first moment indicates the moment when the terminal successfully switches from the serving cell to the first cell; or, the first moment indicates the moment when the terminal sends a switching completion message to the first cell.

[0172] In some embodiments, the first moment may be the moment when the measurement result of the serving cell and the measurement result of the first cell meet the conditions specified by the measurement event. For example, taking the A3 event as an example, the first moment may be the moment when Mn1+Ofn1+Ocn1–Hys1>Mp1+Ofp1+Ocp1+Off1 is satisfied. Mn1 represents the measurement result of the first cell. Ofn1 represents the offset associated with the measurement object corresponding to the first cell. Ocn1 represents the offset associated with the first cell. Mp1 represents the measurement result of the serving cell. Ofp1 represents the offset associated with the measurement object corresponding to the serving cell. Ocp1 represents the offset associated with the serving cell. The measurement object may, for example, indicate the time domain, frequency domain position, subcarrier spacing, etc. of the reference signal. Hys1 represents the hysteresis of the measurement event, and off1 represents the offset of the measurement event. Accordingly, the second moment may be the moment when the measurement result of the first cell and the measurement result of the second cell meet the conditions specified by the measurement event.

[0173] In some embodiments, the first moment may be the moment when the measurement result of the serving cell and the measurement result of the first cell meet the conditions specified by the measurement event and continue to meet the conditions for more than a specified time. For example, taking the A3 event as an example, the first moment may be the moment when the duration of Mn1+Ofn1+Ocn1–Hys1>Mp1+Ofp1+Ocp1+Off1 reaches the first time trigger (timeToTrigger). For example, the moment when the measurement result of the serving cell and the measurement result of the first cell begin to meet Mn1+Ofn1+Ocn1–Hys1>Mp1+Ofp1+Ocp1+Off1 is the third moment, and the first moment can be obtained based on the third moment through the first time trigger. Correspondingly, the second moment may be the moment when the measurement result of the first cell and the measurement result of the second cell meet the conditions specified by the measurement event and continue to meet the conditions for more than a specified time.

[0174] In some embodiments, the first moment may represent the moment when the serving cell begins handover to the first cell, and the second moment may be the moment when the first cell begins handover to the second cell. When handover to the first cell begins when the measurement results of the serving cell and the measurement results of the first cell meet the reporting conditions, or when handover to the first cell begins after a period of time after the measurement results of the serving cell and the measurement results of the first cell meet the reporting conditions, the terminal may predict the moment when handover from the serving cell to the first cell begins.

[0175] In some embodiments, the first moment may represent the moment when the handover from the serving cell to the first cell is completed. For example, the terminal may predict the moment when the serving cell starts to switch to the first cell and predict the duration required for the handover. Adding the duration required for the handover to the moment when the handover starts, the moment when the terminal completes the handover from the serving cell to the first cell is obtained, which is the first moment. It can be understood that when the first moment represents the moment when the serving cell starts to switch to the first cell, after reporting the first moment to the network device, the network device can determine the moment when the handover is completed based on the first moment and the duration required for the handover, and then predict the ToS. Correspondingly, the second moment may represent the moment when the handover from the first cell to the second cell is completed.

[0176] In some embodiments, the first moment represents the moment when the terminal sends a handover complete message to the first cell. After the terminal successfully switches to the first cell, it may send a handover complete message to the first cell. For example, the handover complete message may be an RRC reconfiguration complete (RRCReconfigurationComplete) message. That is, when the terminal sends the handover complete message to the first cell, it indicates that the terminal has successfully switched to the first cell. Therefore, the terminal can predict the moment when the terminal sends the handover complete message to the first cell and use this moment as the first moment. Correspondingly, the terminal can predict the moment when the terminal sends the handover complete message to the second cell and use this moment as the second moment.

[0177] In some embodiments, the first information may also be used to indicate at least one of the following: a predicted corresponding measurement event; and a predicted time window length.

[0178] In some embodiments, the first information may be used to indicate a predicted corresponding measurement event. The measurement event may be understood as a criterion for determining whether to perform a cell handover. For example, when the measurement results of the serving cell and the neighboring cell meet the measurement event, a handover may be performed from the serving cell to the neighboring cell. The terminal may predict a first moment and a second moment based on the measurement event. For example, the moment when the measurement results of the serving cell and the first cell meet the measurement event may be predicted. Generally, a cell handover may be initiated when the measurement event is met. Therefore, the moment when the measurement event is met is the first moment. For another example, the moment when the measurement results of the first cell and the second cell meet the measurement event may be predicted, which is the second moment. The first moment may be understood as the moment when the serving cell and the first cell meet the measurement event, or may be understood as the moment when the terminal starts handover from the serving cell to the first cell. It can be understood that predicting the corresponding measurement event includes at least predicting the measurement event corresponding to the first moment and predicting the measurement event corresponding to the second moment. In the embodiments of the present disclosure, the measurement event corresponding to the predicted first moment and the measurement event corresponding to the predicted second moment may be the same or different.

[0179] In some embodiments, the first information can be used to indicate the length of the predicted time window. That is, the first information can indicate the time period over which the terminal predicts the first moment and the second moment based on the AI ​​model. The first moment and the second moment are used to predict the ToS of the first cell, and the time window length indicated by the first information can be understood as the maximum time period from the prediction moment to the prediction of the possible ToS of the first cell. Among them, the possible first cell means that when the terminal performs cell switching, the serving cell changes, and the first cell corresponding to the serving cell also changes, that is, there may be more than one first cell. For example, within the time window length, assuming that from the pre-stored moment, the serving cell of the terminal is cell A and the first cell is cell B, the terminal can predict the ToS of first cell B. When the terminal switches from cell A to cell B, then for the terminal, cell B is the serving cell, and for serving cell B, its corresponding first cell is assumed to be cell C, then the terminal can predict the ToS of cell C.

[0180] In some embodiments, the name of the first information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0181] Step S2102 : The network device 102 sends a first related configuration to the terminal 101 .

[0182] In some embodiments, the terminal 101 receives a first related configuration sent by the network device 102. The first related configuration is used to predict a first time.

[0183] In some embodiments, the first related configuration may include at least one of the following: reference signal type, measurement quantity type, first time trigger, offset (off) of measurement event, hysteresis (Hys) of measurement event, offset of serving cell, offset of first cell.

[0184] In some embodiments, the first related configuration may include a reference signal type. For example, the reference signal type may include a synchronization signal Block (SSB) or a channel state information reference signal (CSI-RS). The terminal may predict the first moment and the second moment based on the reference signal type. For example, the terminal may predict the moment when the measurement result of the SSB of the serving cell and the measurement result of the SSB of the first cell meet the measurement event, that is, the first moment. For another example, the terminal may predict the moment when the measurement result of the SSB of the first cell and the measurement result of the SSB of the second cell meet the measurement event, that is, the second moment. For another example, the terminal may predict the moment when the measurement result of the CSI-RS of the first cell and the measurement result of the CSI-RS of the second cell meet the measurement event, that is, the second moment. The network device may indicate the type of the reference signal through the first information, so that the terminal can flexibly predict the first moment and the second moment based on different reference signals indicated by the network device.

[0185] In some embodiments, the first related configuration may include the type of measurement quantity. For example, the measurement quantity may include at least one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), and Signal-to-Noise and Interference Ratio (SINR). The terminal may predict the first moment and the second moment based on the measurement quantity. For example, the terminal may predict the RSRP of the reference signal of the serving cell and the RSRP of the reference signal of the first cell, and the relationship between the two RSRPs satisfies the moment of the measurement event, i.e., the first moment. For another example, the terminal may predict the RSRQ of the reference signal of the first cell and the RSRQ of the reference signal of the second cell, and the relationship between the two RSRQs satisfies the moment of the measurement event, i.e., the second moment. Examples of the terminal predicting the first moment and the second moment based on the measurement quantity are not limited to this, and the present disclosure does not give examples one by one. The network device may indicate the type of measurement quantity through the first information, so that the terminal can flexibly predict the first moment and the second moment based on the measurement quantity indicated by the network device.

[0186] In some embodiments, the first related configuration may include a first time trigger. The time trigger (timeToTrigger) can be understood as a preset duration, that is, reaching the first time trigger can be understood as passing a preset duration. The first time trigger can be used to predict the first moment. For example, when the measurement event is A3, the cell switching is started after the time that the condition is continuously satisfied between the measurement result of the serving cell of the terminal and the measurement result of the first cell exceeds the time trigger. That is, satisfying the measurement event A3 includes that the measurement result of the serving cell and the measurement result of the first cell meet the condition, and the time that the condition is continuously satisfied exceeds the time trigger. That is, the first moment is from the moment when the measurement result of the serving cell and the measurement result of the first cell meet the condition, after the time trigger. Therefore, the network device indicates the first time trigger for predicting the first moment, so that the terminal can obtain the first moment by predicting the moment when the condition is satisfied between the measurement result of the serving cell and the measurement result of the first cell, and adding the first time trigger on the basis of the moment.

[0187] In some embodiments, the first related configuration may include an offset of a serving cell, where the offset of the serving cell includes an offset associated with a measurement object corresponding to the serving cell, i.e., Ofp1, and an offset associated with the serving cell, i.e., Ocp1. The measurement object may, for example, indicate a time domain or frequency domain position, subcarrier spacing, etc. of a reference signal.

[0188] In some embodiments, the first related configuration may include an offset of the first cell, wherein the offset of the first cell may include an offset associated with the measurement object corresponding to the first cell, ie, Ofn1, and an offset associated with the first cell, ie, Ocn1.

[0189] In some embodiments, the first correlation configuration may include an offset (off) 1 and a hysteresis (Hys) 1 corresponding to the measurement event and a first time trigger.

[0190] In some embodiments, the first related configuration may be a configuration of a measurement event. The configuration of the measurement event includes an offset of the serving cell, an offset of the neighboring cell, a first time trigger, a reference signal type for measurement, a measurement quantity type, and the like. The terminal receiving the first related configuration may be the terminal receiving the configuration of the measurement event. The terminal predicting the first moment using the first related configuration may be the terminal predicting the first moment using the configuration of the measurement event. That is, the terminal may predict the moment when Mn1+Ofn1+Ocn1–Hys1>Mp1+Ofp1+Ocp1+Off1. From this moment on, when the first time trigger is reached, the first moment is obtained. Ofn1 and Ocn1 are the offsets of the neighboring cell in the configuration of the measurement event. Ofp1 and Ocp1 are the offsets of the serving cell in the configuration of the measurement event. Mn1 represents the measurement result of the first cell; Mp1 represents the measurement result of the serving cell. The reference signal type and measurement quantity type corresponding to the measurement result may be determined based on the reference signal type and measurement quantity type in the configuration of the measurement event.

[0191] In some embodiments, the first related configuration may be a configuration solely used to predict the first moment, that is, the first related configuration and the configuration of the measurement event may be two independent configurations.

[0192] In some embodiments, the first information and the first related configuration may be sent together to the terminal. For example, if the first related configuration is a configuration for a measurement event, the first information may be included in the first related configuration. That is, the configuration for the measurement event may instruct the terminal to predict the first and second moments based on AI, and may also indicate the corresponding measurement event, the length of the predicted time window, etc. For another example, if the first related configuration is a configuration solely for predicting the first moment, the first related configuration may be included in the first information. That is, when instructing the terminal to predict the first and second moments based on the AI ​​model, the first related configuration may also be indicated.

[0193] In some embodiments, the first relevant configuration and the first information may be sent independently. If the first relevant configuration and the first information are sent independently, the order of the sending steps may be arbitrary, that is, the order of step S2101 and step S2102 may be arbitrary, and the first information may be sent first, followed by the first relevant configuration. Alternatively, the first relevant configuration may be sent first, followed by the first information, which is not limited in this disclosure.

[0194] In some embodiments, the terminal may predict a first moment based on Ofp1, Ocp1, Ofn1, Ocn1, off1, and Hys1 in the first related configuration and a first time trigger. For example, the terminal may predict a moment when Mn1+Ofn1+Ocn1–Hys1>Mp1+Ofp1+Ocp1+Off1. The first moment is obtained when the first time trigger is reached starting from this moment. Mn1 represents the measurement result of the first cell, and Mp1 represents the measurement result of the serving cell.

[0195] Step S2103: Terminal 101 determines a second related configuration based on the first related configuration.

[0196] In some embodiments, terminal 101 may determine a second related configuration based on the first related configuration. That is, the second related configuration may be estimated based on the first related configuration. The second related configuration is used to predict the second time. Taking measurement event A3 as an example, the second related configuration may include an offset for the first cell, namely, Ofp2 and Ocp2 when the first cell serves as the serving cell, where Ofp2 is equal to Ofn1 and Ocp2 is equal to Ocn1. The second related configuration may also include an offset for the second cell, namely, Ofn2 and Ocn2 when the second cell serves as a neighboring cell of the serving cell. The second related configuration may include Off2 and Hys2 corresponding to the measurement event, as well as a second time trigger. The second time is predicted based on the second related configuration, for example, a time when Mn2+Ofn2+Ocn2–Hys2>Mp2+Ofp2+Ocp2+Off2 is predicted. The second time is obtained when the second time trigger is reached starting from this time. Mn2 represents the measurement result of the second cell, and Mp2 represents the measurement result of the first cell.

[0197] In some embodiments, the first related configuration includes an offset of the first cell, namely Ofn1 and Ocn1. Ofp2 and Ocp2 in the second related configuration are known to the terminal based on the first related configuration, namely Ofp2 is equal to Ofn1, and Ocp2 is equal to Ocn1. However, Ofn2, Ocn2, off2, Hys2, and the second time trigger are unknown. The second related configuration can be determined based on the first related configuration in the following manner: the offset and hysteresis of the A3 event in the first related configuration are determined as the offset and hysteresis of the A3 event in the second related configuration; the first time trigger in the first related configuration is determined as the second time trigger in the second related configuration; the offset of the specific cell in the first related configuration is determined as the offset of the second cell in the second related configuration; wherein the specific cell includes the serving cell, or a cell other than the first cell among the neighboring cells of the serving cell.

[0198] In some embodiments, the cell-independent related configuration in the second related configuration may be determined to be the same as the first related configuration. For example, the offset and hysteresis of the A3 event in the first related configuration may be determined to be the offset and hysteresis of the A3 event in the second related configuration. The first time trigger in the first related configuration may be determined to be the second time trigger in the second related configuration.

[0199] In some embodiments, the offset of a specific cell in the first related configuration may be determined as the offset of a second cell in the second related configuration. The specific cell may include a serving cell, or a cell other than the first cell among the neighboring cells of the serving cell. The related configurations between neighboring cells may be the same, and the second cell is a neighboring cell of the first cell, that is, the related configuration of the second cell may be the same as the related configurations of other neighboring cells of the first cell. Since the first cell is a neighboring cell of the serving cell, the neighboring cells of the first cell may include the serving cell and other neighboring cells of the serving cell other than the first cell. That is, the terminal may determine the offset of the serving cell as the offset of the second cell. Alternatively, the terminal may determine the offset of other cells other than the first cell among the neighboring cells of the serving cell as the offset of the second cell.

[0200] In step S2104, the terminal 101 predicts the first moment and the second moment based on the AI ​​model.

[0201] In some embodiments, the terminal may predict a first moment and a second moment based on the AI ​​model, where the first moment and the second moment are used to predict the ToS of the terminal in the first cell after switching from the serving cell to the first cell. The first moment and the second moment are described in the above embodiments and are not repeated here.

[0202] In some embodiments, the terminal may predict the ToS based on the first time and the second time. For example, the terminal may assume that T1 and T2 are equal and determine the difference between the first time and the second time as the ToS. For another example, the terminal may determine the ToS based on the estimated T1 and T2.

[0203] In some embodiments, the network device may predict the ToS based on the first time and the second time. For example, the terminal reports the first time and the second time to the network device, and the network device calculates the ToS based on the first time, the second time, T1, and T2.

[0204] In some embodiments, the terminal predicts the first moment in the following manner: predicting a third moment, where the third moment represents the moment when a condition is satisfied between the measurement result of the serving cell and the measurement result of the first cell; and obtaining the first moment after a first time trigger is passed from the third moment. The first time trigger is used to trigger a handover of the terminal from the serving cell to the first cell when the duration of time during which the condition is satisfied between the measurement result of the serving cell and the measurement result of the first cell reaches the first time trigger. Satisfying the condition refers to satisfying a condition in the measurement event. For example, for measurement event A3, the condition is Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off.

[0205] In some embodiments, the third time can also be obtained by terminal measurement. For example, the terminal can predict the third time based on the AI ​​model before the third time, and determine the first time based on the third time for use in predicting the ToS. That is, the terminal can predict the ToS before the third time. For another example, the terminal can determine through actual measurement that the measurement results of the current serving cell and the measurement results of the first cell meet the conditions, and then determine the current time as the third time. The first time is determined based on the third time for use in predicting the ToS. That is, the terminal can predict the ToS at the third time.

[0206] In some embodiments, the terminal may predict, after predicting the third moment, whether the measurement results of the serving cell and the measurement results of the first cell can continuously meet the conditions starting from the third moment and before reaching the first time trigger. If it is predicted that the conditions can be continuously met, the moment when the first time trigger is reached is used as the first moment. If it is predicted that the conditions cannot be continuously met, the prediction of the third moment is stopped or re-predicted. It can be understood that only after the conditions are continuously met, that is, when the measurement event is met, can the terminal switch from the serving cell to the first cell. Therefore, when it is predicted that the conditions are continuously met, the first moment can be determined, and the second moment can be continued to be predicted to determine whether to switch from the serving cell to the first cell. If the conditions cannot be continuously met, the terminal will not perform cell switching, so the prediction of the third moment can be stopped or re-predicted.

[0207] In some embodiments, the first time trigger configured by the network device may be 0, then the first moment is the third moment, and the terminal may predict the third moment and use the third moment as the first moment to determine the ToS of the first cell.

[0208] In some embodiments, the terminal predicts the second moment in the following manner: predicting the fourth moment, the fourth moment indicating the moment when the condition is met between the measurement result of the first cell and the measurement result of the second cell; starting from the fourth moment and passing through the second time trigger, the second moment is obtained, and the second time trigger is used to trigger the terminal to switch from the first cell to the second cell when the duration for which the condition is met between the measurement result of the first cell and the measurement result of the second cell reaches the second time trigger.

[0209] In some embodiments, after predicting the fourth time instant, the terminal may predict whether the measurement results of the first cell and the measurement results of the second cell can continuously meet a condition from the fourth time instant until the second time trigger is reached. If the condition is predicted to be continuously met, the time when the second time trigger is reached is used as the second time instant. If the condition is predicted to be unsatisfactory, the prediction of the fourth time instant is stopped or re-predicted.

[0210] In some embodiments, the first time trigger configured by the network device may be 0. If the terminal determines the second time trigger in the second related configuration based on the first time trigger in the first related configuration, and the second time trigger is also equal to 0, then the second time is the fourth time. The terminal may predict the fourth time and use the fourth time as the second time to determine the ToS of the first cell.

[0211] It is understood that this disclosure primarily describes a network device sending first information and / or a first related configuration to a terminal, instructing the terminal to predict a first time and a second time based on an AI model for use in determining a ToS. However, the network device may also independently predict the first time and the second time based on the AI ​​model and determine the ToS based on the first time and the second time, and this disclosure does not limit this.

[0212] It can be understood that, in the present disclosure, satisfying a measurement event means satisfying a reporting condition, and the two can be used interchangeably.

[0213] Step S2105 , the terminal 101 sends the first moment and / or the second moment to the network device 102 ; or the terminal 101 sends the difference between the first moment and the second moment to the network device 102 .

[0214] In some embodiments, the network device 102 receives the first time and / or the second time sent by the terminal 101 , or the network device 102 receives the difference between the first time and the second time sent by the terminal 101 .

[0215] In some embodiments, the network device may determine the ToS based on the first moment and the second moment, or determine the ToS based on the difference between the first moment and the second moment. The specific method may refer to the above embodiment, and this disclosure will not elaborate on it here.

[0216] In some embodiments, when the ToS is greater than a threshold, the terminal switches from the serving cell to the neighboring cell. For example, when the network device determines that the ToS is greater than the threshold, the base station of the serving cell, i.e., the network device 102, sends a handover request message to the base station of the first cell.

[0217] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2104 may be implemented as an independent embodiment, but is not limited thereto.

[0218] In some embodiments, step S2101, step S2102, step S2103, and step S2105 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0219] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .

[0220] FIG2b is a schematic diagram illustrating an interaction of a communication method according to an embodiment of the present disclosure. As shown in FIG2b , the present disclosure embodiment relates to a communication method for use in a communication system 100, the method comprising:

[0221] Step S2201: The network device 102 sends first information to the terminal 101.

[0222] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0223] Step S2202 : The network device 102 sends a first related configuration to the terminal 101 .

[0224] The optional implementation of step S2202 can refer to the optional implementation of step S2102 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0225] Step S2203 , the network device 102 sends second information to the terminal 101 .

[0226] In some embodiments, the terminal 101 receives second information sent by the network device 102. The second information is used to indicate a second related configuration.

[0227] In some embodiments, the network device may also send the first relevant configuration and the second relevant configuration independently, or may send the first relevant configuration and the second relevant configuration together.

[0228] In some embodiments, network device 102, i.e., the base station of the serving cell, may obtain the configuration of the second cell from the base station of the first cell or the base station of the second cell. Since the second cell is a neighboring cell of the first cell, the network device may obtain the configuration of the second cell from the base station of the first cell.

[0229] In some embodiments, the second related configuration includes at least one of the following: an identifier of the second cell; a configuration corresponding to the measurement event; a configuration corresponding to the second cell; and a configuration of neighboring cells of the first cell except the second cell.

[0230] In some embodiments, the second related configuration may include an identifier of the second cell, for example, the identifier of the second cell includes a physical cell identifier of the second cell and a frequency of the second cell. For another example, the identifier of the second cell includes the physical cell identifier of the second cell and a measurement object corresponding to the second cell.

[0231] In some embodiments, the second related configuration may include a configuration corresponding to a measurement event. Taking A3 as an example, the configuration corresponding to the measurement event includes off and Hys.

[0232] In some embodiments, the second related configuration may include a configuration corresponding to the second cell. Taking A3 as an example, the configuration corresponding to the second cell is an offset of the second cell.

[0233] In some embodiments, the second related configuration may include configurations of other cells in neighboring cells of the first cell except the second cell. For example, if the target cell to be switched by the first cell becomes another cell, the configurations of the other cells may be used to predict the second time.

[0234] In some embodiments, the second information may be sent based on radio resource control (RRC) signaling.

[0235] In some embodiments, the name of the second information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0236] Step S2204: Terminal 101 determines a second related configuration based on the second information.

[0237] In some embodiments, the terminal may determine the second relevant configuration based on the second information sent by the network device. It is understandable that in some cases, the relevant configurations between neighboring cells may differ greatly. That is, the relevant configuration of the second cell may not be determined based on the relevant configurations of other neighboring cells of the first cell. Alternatively, the neighboring cells of the first cell may not include the serving cell, and the neighboring cells of the serving cell other than the first cell, that is, the neighboring cell set of the serving cell and the neighboring cell set of the first cell may be different. Therefore, the configuration of the second cell cannot be determined based on the configuration of the serving cell, and the configuration of the second cell cannot be determined based on the configurations of other cells in the neighboring cells of the serving cell other than the first cell. Therefore, the second information sent by the network device 102 can be received, and the second relevant configuration can be determined based on the second information.

[0238] In step S2205, the terminal 101 predicts the first moment and the second moment based on the AI ​​model.

[0239] In some embodiments, if the terminal determines the second related configuration based on the second information, and the second related configuration indicated by the second information is 0, then the second time is the fourth time. The terminal may predict the fourth time and use the fourth time as the second time to predict the ToS of the first cell.

[0240] The optional implementation of step S2205 can refer to the optional implementation of step S2104 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0241] Step S2206 , the terminal 101 sends the first moment and / or the second moment to the network device 102 ; or the terminal 101 sends the difference between the first moment and the second moment to the network device 102 .

[0242] The optional implementation of step S2206 can refer to the optional implementation of step S2105 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0243] The communication method involved in the embodiment of the present disclosure may include at least one of steps S2201 to S2206. For example, step S2205 may be implemented as an independent embodiment, but is not limited thereto.

[0244] In some embodiments, step S2201, step S2202, step S2203, step S2204, and step S2206 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0349] The optional implementation of step S5102 can be found in S2105 of FIG. 2 a and other related parts of the embodiment involved in FIG. 2 a , which will not be described in detail here.

[0350] The present disclosure provides a communication method as follows:

[0351] In some embodiments, the UE predicts switching based on the triggering of the AI-predicted measurement event, and predicts whether the measurement event will continue to be triggered after the switch to predict the residence time of the cell. The predicted cell can be an intra-frequency cell (intra-frequency). An inter-frequency cell (inter-frequency), or an inter-RAT cell (inter-RAT). In the current NR system, the UE evaluates the actual measurement results and reports the corresponding measurement results after the measurement results meet the entering condition for a duration that reaches the configured timeToTrigger. For the convenience of description in the following disclosure, "predicted measurement event triggering" refers to "the duration that the AI-predicted measurement results meet the entering condition for a duration that reaches the configured timeToTrigger".

[0352] FIG. 6 is a schematic diagram showing the AI prediction of the cell residence time according to an exemplary embodiment of the present disclosure. As shown in FIG. 6, the measurement quantity is RSRP, and the measurement event is event A3. At time t1, neighboring cell A satisfies the entering condition of event A3 with respect to the serving cell. The evaluation of event A3 at time t1 can be an evaluation based on actual measurement results or an evaluation based on AI prediction, that is, predicting whether the entering condition of event A3 is satisfied at t1 at time <t1>. According to the AI prediction, it is determined whether neighboring cell A can continuously satisfy the entering condition of event A3 with respect to the serving cell PCell from time t1 to t2 (t2 – t1 = TTT1). Here, TTT1 represents timeToTrigger1. If it can, then according to the above definition, "prediction event trigger". That is, at time t <t2, the AI can predict that the prediction event will be triggered at time t2. Assume that at time t, the AI can continue to predict the situation after t2. Assume that the network switches the UE to cell A. The handover takes a certain amount of time (indicated by t3 - t2 in FIG. 6), including the UE sending a measurement report, the source gNB sending a handover request message to the target gNB, the target gNB performing permission control and sending a handover request confirmation message to the source gNB, the source gNB forwarding the RRCReconfiguration message to the UE, the UE synchronizing with the target cell, initiating a random access process to access the target cell, and replying to the target gNB with RRCReconfigurationComplete. If the AI predicts that at time t4, neighboring cell B satisfies the entering condition of event A3 with respect to cell A, and predicts that neighboring cell B can continuously satisfy the entering condition of event A3 with respect to cell A from time t4 to t5 (t5 – t4 = TTT2), that is, the prediction event is triggered, then it can be predicted that the network will hand over the UE from cell A to cell B, and the handover time corresponds to t6 - t5. ToS = t6 – t3. If it is assumed that the two handover times are equal, that is, t3 – t2 = t6 – t5, then t6 – t3 = t5 – t2 can be obtained. That is, ToS = t6 – t3 = t5 – t2. Thus, the cell residence time can be obtained from the difference between the times of the two prediction event triggers. In this example, cell B is different from the PCell. According to the actual deployment situation and the movement of the UE, it is possible that cell B is the same as the PCell, that is, the AI predicts that the UE is first handed over from the PCell to cell A and then handed back from cell A to the PCell.

[0353] In some embodiments, t1 may be the third time, t2 may be the first time, t4 may be the fourth time, and t5 may be the second time. If the two handover times are equal, the ToS may be the difference between the first time and the second time. TTT1 may be the first time trigger, and TTT2 may be the second time trigger. The source base station, i.e., the base station of the serving cell, may be network device 102, and the target base station may be the base station of the first cell.

[0354] In some embodiments, the network's configuration information for AI-predicted cell dwell time can be sent through RRC signaling. The configuration information may include whether AI is used to predict and report cell dwell time for a specific measurement event, the length of the AI ​​prediction time window (i.e., starting from the prediction moment, how long the possible cell dwell time is predicted at most), the predicted reference signal type (SSB or CSI-RS), the type of measurement quantity (RSRP, RSRQ, SINR), timeToTrigger, etc. Some of the above configuration information (such as the type of reference signal, the type of measurement quantity, timeToTrigger, etc.) can share the configuration of existing measurement events, or can be configured separately for the predicted cell dwell time.

[0355] In some embodiments, when predicting the cell dwell time, it is necessary to predict whether the predicted event will trigger the neighboring cell after the first predicted event is triggered, assuming that the UE switches to the neighboring cell, that is, when the neighboring cell is used as the serving cell, whether the duration for which the measurement result of another cell meets the entering condition can reach the configured timeToTrigger. At this time, the relevant configuration of the neighboring cell regarding the measurement event is required, that is, the offset (offset) Ofn and Ocn of the neighboring cell, the offset Ofp and Ocp of the SpCell, the offset Off of the A3 event configuration, the hysteresis Hys of the A3 event, the type of reference signal (SSB or CSI-RS), the type of measurement quantity (RSRP, RSRQ, SINR), timeToTrigger, etc. For predicting the cell dwell time, there are two ways to determine the relevant configuration of the neighboring cell regarding the measurement event.

[0356] In some embodiments, the configuration of the neighboring cell regarding the measurement event is inferred based on the existing measurement configuration. Taking Event A3 as an example, the entering condition of Event A3 is: Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off, where the offset (Off) of the A3 event, the hysteresis (Hys) of the A3 event, and timeToTrigger are configured in the IE EventTriggerConfig. When predicting the cell dwell time, it can be assumed that the neighboring cell uses the same Off, Hys, and timeToTrigger. Ofn is the offset related to the measurement object corresponding to the neighboring cell (i.e., offsetMO in the measObjectNR corresponding to the neighboring cell), and Ofp is the offset related to the measurement object corresponding to the SpCell (i.e., offsetMO in the measObjectNR corresponding to the SpCell). Ocn is the offset specific to the neighboring cell (i.e., cellIndividualOffset defined in the measObjectNR corresponding to the neighboring cell frequency). If not configured, it is set to 0. Ocp is the offset specific to the SpCell (i.e., cellIndividualOffset defined in the measObjectNR corresponding to the SpCell). If not configured, it is set to 0. When predicting whether a measurement event is triggered after switching to a neighboring cell (assuming the neighboring cell is cell A), the values ​​of Ofn, Ofp, Ocn, and Ocp can be set according to the existing measurement configuration. For example, Ofn is the offset associated with the measurement object corresponding to the neighboring cell other than cell A (which can be the original PCell), Ofp is the offset associated with the measurement object corresponding to cell A, Ocn is the offset specific to the neighboring cell other than cell A (which can be the original PCell), and Ocp is the offset specific to cell A.

[0357] In some embodiments, the network provides the configuration related to the measurement event of the neighboring cell, for example, by providing these configurations through RRC signaling. Since the configuration related to the measurement event of the neighboring cell may be different from that of the current serving cell, and the physical location of the neighboring cell and the current serving cell is different, the neighboring cell sets of the two are not exactly the same. Therefore, the network needs to provide the configuration related to the measurement event of the neighboring cell. The network needs to provide the identifier of the neighboring cell, such as the frequency / measurement object corresponding to the neighboring cell and the physical cell identifier of the neighboring cell. The relevant configuration may include the configuration of the measurement event, such as the offset of the event, the hysteresis of the event, timeToTrigger, the offset related to the measurement object (corresponding to Ofp and Ofn), the offset related to the cell in the measurement object (corresponding to Ocp and Ocn), etc. It may be necessary to provide information about one or more measurement objects, and to provide zero or more cell-related information within each measurement object. The relevant configuration about the measurement event can be sent between base stations through signaling of the inter-base station interface (for example, NGAP signaling on the Xn interface). Another way is for OAM to provide the base station with the configuration related to the measurement event of the neighboring cell.

[0358] In some embodiments, after predicting the cell dwell time, the UE may report information about the cell dwell event according to the network configuration. This information includes the identifier of the neighboring cell and the corresponding dwell time information. One method of reporting the identifier of the neighboring cell is to report the frequency or measurement object corresponding to the neighboring cell and the physical cell identifier of the neighboring cell. The corresponding dwell time reporting method may be:

[0359] In some embodiments, the UE reports the time when cell A meets the predicted measurement event trigger relative to PCell, and then the time when cell B meets the measurement event trigger relative to cell A. In this method, the network calculates the UE's stay event in cell A based on the handover time.

[0360] In some embodiments, the UE reports the difference between the time when cell B meets the measurement event triggering requirement relative to cell A and the time when cell A meets the predicted measurement event triggering requirement relative to PCell.

[0361] In some embodiments, the time when cell A meets the predicted measurement event triggering requirement relative to the PCell may be a first time, and the time when cell B meets the measurement event triggering requirement relative to cell A may be a second time.
