Description

[Technical Field]

[0001] This application claims priority to China Patent Application No. 202310492219.7, titled “Handover Configuration Method and Apparatus,” filed with the China National Intellectual Property Administration on 4 May 2023, and China Patent Application No. 202310647088.5, titled “Handover Configuration Method, Terminal Device, and Network Device,” filed with the China National Intellectual Property Administration on 31 May 2023, both of which are incorporated herein by reference in their entirety.

[0002] This application relates to the field of wireless communications, and more particularly to handover configuration methods, terminal devices, and network devices. [Background technology]

[0003] In a wireless communication system, when the quality of the radio link between a terminal device and a source cell deteriorates, and / or when the quality of the radio link between a terminal device and a cell other than the source cell improves, the terminal device is handed over from the source cell to a target cell to ensure link quality when transmitting messages between the terminal device and the network device.

[0004] However, the cell handover procedure has problems with low accuracy in handing over to the target cell and a high probability of handover failure. [Overview of the project]

[0005] To solve the aforementioned technical problems, this application provides a handover configuration method, terminal device, and network device to improve the accuracy and success rate of cell handover. To achieve the aforementioned objectives, this application employs the following technical solutions.

[0006] According to a first embodiment, a handover configuration method is provided. This method may be performed by a first terminal device or by a chip in the first terminal device. In the following description, an example in which the method is performed by a first terminal device is used. The method includes the first terminal device receiving downlink signaling from a first network device in a first cell and determining configuration information based on the downlink signaling, the configuration information being: Configuration 1: An event related to probability, the probability includes the probability of a cell handover or the probability that a second cell will function as a target cell, the second cell belonging to a first cell set, the first cell set including: a first cell, at least one intra-radio access technology adjacent cell of the first cell, or at least one inter-radio access technology adjacent cell of the first cell, In configuration 1, when the target cell is different from the first cell, the target cell is the cell accessed by the first terminal device after the first terminal device performs a cell handover, and a cell handover is an operation that can be performed by the first terminal device, or when the target cell overlaps with the first cell, it means that the first terminal device cannot perform a cell handover, event, Configuration 2: Determining the first information based on the first submodel, where the first submodel is part of the following models: an artificial intelligence (AI) model or a machine learning (ML) model, and the first information is used for cell handover. Configuration 3: An event relating to a quantifiable quantity at a first point in time or a quantifiable quantity during a first time period, wherein the first point in time includes a future point in time, the first time period includes a future time period, and the quantifiable quantity at the first point in time or the quantifiable quantity during the first time period is acquired by a first terminal device through prediction, the event Show at least one of them.

[0007] In other words, the first network device uses configuration information to configure one or more configurations for the first terminal device, such as configuration 1, configuration 2, or configuration 3, in order to optimize the cell handover-related configuration.

[0008] Specifically, in Configuration 1, the events in Configuration 1 are related to probability and are predictive and predictive. For example, the probability that the first cell functions as a target cell can represent the confidence level that the first cell functions as a target cell. The probability of a cell handover can represent the need to perform a cell handover.

[0009] In configuration 2, the first information is obtained by performing a process that uses the first submodel. Since the first submodel is part of the AI / ML model, the first information does not indicate the target cell, but it is used for cell handover.

[0010] In configuration 3, the events of configuration 3 relate to a metric at a future point in time or over a future period of time, and are also predictive and forward-looking.

[0011] With respect to the events defined in Configuration 1 and Configuration 3, other parameters such as thresholds and offset values ​​corresponding to the events are also referenced. Similarly, in Configuration 2, after the first terminal device determines the first information based on the first submodel, the first network device determines whether to perform a cell handover based on the first information, or the first information and network-side reference information (e.g., load status of each cell), or determines the target cell based on the first information, or the first information and network-side reference information. Compared to determining the target cell based solely on a measured quantity of the configured time period, or simply selecting the cell with the highest probability as the target cell, the optimized configuration of this application allows the communication device to refer to more information to predict whether to perform a cell handover or determine the target cell, in order to help improve the accuracy and success rate of the handover.

[0012] In a possible design, configuration 1 is used to constitute at least one of events 1 through 5, where the probability includes the probability that the second cell acts as the target cell. Events 1 through 5 are described as follows:

[0013] Event 1: The probability that the first cell functions as a target cell is greater than the threshold. Starting conditions: M1>Thresh, and Termination condition: M1 <Thresh、ただし、 M1 indicates the probability that the first cell will function as the target cell. Thresh indicates the threshold for event 1, where the first cell is the same as the second cell.

[0014] For example, Event 1 is used to stop inter-frequency / inter-radio access technology measurements. In other words, there is a high probability that the first cell will function as a target cell, and the first terminal device may stop measurements, such as inter-frequency / inter-radio access technology measurements, in order to reduce the terminal's power consumption.

[0015] Event 2: The probability that the first cell functions as the target cell is less than the threshold, Start condition: M1 < Thresh, and End condition: M1 > Thresh, provided that M1 represents the probability that the first cell functions as the target cell, Thresh represents the threshold of Event 2, and the first cell is the same as the second cell.

[0016] For example, Event 2 is used to start inter-frequency / inter-radio access technology measurements. In other words, there is a low probability that the first cell functions as the target cell, and the first terminal device may start measurements, such as inter-frequency / inter-radio access technology measurements. When the measurement amount of inter-frequency / inter-radio access technology measurements is used for cell handover, the inter-frequency / inter-radio access technology measurements are started in a timely manner. This helps to reduce unnecessary delays in cell handover.

[0017] Event 3: The probability that the second cell functions as the target cell is greater than the probability that the first cell functions as the target cell, and the first cell is the same as the second cell, Start condition: M2 > M1, and End condition: M2 < M1, provided that M2 represents the probability that the second cell functions as the target cell, M1 represents the probability that the first cell functions as the target cell.

[0018] For example, in Event 3, the second cell is at least one in-band adjacent cell of the first cell, such as an in-frequency adjacent cell or an inter-frequency adjacent cell. Correspondingly, Event 3 can be used to initiate an in-frequency / inter-frequency handover. In other words, there is a high probability that an in-frequency / inter-frequency adjacent cell of the first cell functions as a target cell. In this case, the first terminal device may send a probability-related and / or measurement-related report to the first network device, and the first network device executes a decision based on the report and initiates a cell handover. Correspondingly, the first terminal device may execute a cell handover.

[0019] Event 4: The probability that the second cell functions as a target cell is greater than a threshold, Start condition: M2 > Thresh, and End condition: M2 < Thresh, provided that M2 indicates the probability that the second cell functions as a target cell, Thresh indicates the threshold for Event 4.

[0020] For example, the second cell is at least one in-band adjacent cell of the first cell, such as an in-frequency adjacent cell or an inter-frequency adjacent cell. Correspondingly, Event 4 can be used to initiate an in-frequency / inter-frequency handover.

[0021] In another example, the second cell is at least one inter-band adjacent cell of the first cell. Correspondingly, Event 4 can be used to initiate an inter-band handover.

[0022] Event 5: The probability that the first cell functions as a target cell is less than a first threshold, and the probability that the second cell functions as a target cell is greater than a second threshold, and the first cell is the same as the second cell, Start condition: M < Thresh51 and M2 > Thresh52, and Termination condition: M1 > Thresh51 and / or M2 <Thresh52、ただし、 M1 indicates the probability that the first cell will function as the target cell. M2 indicates the probability that the second cell will function as the target cell. Thresh51 indicates the first threshold for event 5, and Thresh52 indicates the second threshold for event 5.

[0023] For example, the second cell is at least one radio access technology adjacent cell of the first cell, e.g., an in-frequency adjacent cell or an inter-frequency adjacent cell. Correspondingly, event 5 may be used to initiate an in-frequency / inter-frequency handover.

[0024] In another example, the second cell is at least one inter-radio access technology adjacent cell to the first cell. Correspondingly, event 5 may be used to initiate an inter-radio access technology handover.

[0025] In a possible design, configuration 1 is used to constitute at least one of events 1 through 5, where the probability includes the probability that the second cell acts as the target cell. Events 1 through 5 are described as follows:

[0026] Event 1: The probability that the first cell functions as a target cell is greater than the threshold. Starting conditions: M1-Hys>Thresh, and Termination condition: M1+Hys <Thresh、ただし、 M1 indicates the probability that the first cell will function as the target cell. Hys represents the hysteresis parameter for event 1. Thresh indicates the threshold for event 1, where the first cell is the same as the second cell.

[0027] In Event 1, the hysteresis parameter Hys is further referenced, which makes the decision for Event 1 more stable.

[0028] Event 2: The probability that the first cell functions as a target cell is less than the threshold. Starting condition: M1+Hys <Thresh、および Termination condition: M1-Hys>Thresh, however, M1 indicates the probability that the first cell will function as the target cell. Hys shows the hysteresis parameter for event 2. Thresh indicates the threshold for event 2, where the first cell is the same as the second cell.

[0029] In Event 2, the hysteresis parameter Hys is referenced further, which makes the decision for Event 2 more stable.

[0030] Event 3: The probability that the second cell functions as a target cell is greater than the probability that the first cell functions as a target cell, and the first cell is different from the second cell.

[0031] Event 3 includes at least one of Event 31 and Event 32.

[0032] The conditions for Event 31 are: Starting conditions: M2+Of2+Oc2-Hys>M1+Of1+Oc1+Off, and Termination condition: M2+Of2+Oc2+Hys <M1+Of1+Oc1+Off This includes, however, M2 indicates the probability that the second cell will function as the target cell. M1 indicates the probability that the first cell will function as the target cell. Of2 represents the first offset of the probability that the second cell will function as the target cell. Oc2 represents the second offset of the probability that the second cell will function as the target cell. Of1 represents the first offset of the probability that the first cell will function as the target cell. Oc1 represents the second offset of the probability that the first cell will function as the target cell. Hys shows the hysteresis parameters for event 31. "Off" indicates the offset value for event 31.

[0033] Event 31 references more parameters such as Of2, Oc2, Of1, Oc1, Hys, and Off, which makes the decision for Event 31 more accurate, flexible, and stable.

[0034] The conditions for Event 32 are: Starting conditions: M2+Oc2-Hys>M1+Oc1+Off, and Termination condition: M2+Oc2+Hys <M1+Oc1+Off This includes, however, M2 indicates the probability that the second cell will function as the target cell. M1 indicates the probability that the first cell will function as the target cell. Oc2 indicates the offset of the probability that the second cell will function as the target cell. Oc1 represents the offset of the probability that the first cell will function as the target cell. Hys shows the hysteresis parameters for event 32. "Off" indicates the offset value for event 32.

[0035] Event 32 references more parameters such as Oc2, Oc1, Hys, and Off, making the decision for Event 32 more accurate, flexible, and stable.

[0036] Event 4: The probability that the second cell functions as a target cell is greater than the threshold. Starting conditions: M2+Of2+Oc2-Hys>Thresh, and Termination condition: M2+Of2+Oc2+Hys <Thresh、ただし、 M2 indicates the probability that the second cell will function as the target cell. Of2 represents the first offset of the probability that the second cell will function as the target cell. Oc2 represents the second offset of the probability that the second cell will function as the target cell. Hys shows the hysteresis parameter for event 4. Thresh indicates the threshold for event 4.

[0037] In Event 4, more parameters such as Of2, Oc2, and Hys are referenced, which makes the decision for Event 4 more accurate, flexible, and stable.

[0038] Event 5: The probability that the first cell functions as a target cell is less than the first threshold, and the probability that the second cell functions as a target cell is greater than the second threshold, and the first cell is different from the second cell. Starting condition: M1+Hys51<Thresh51かつM2+Of2+Oc2-Hys52> Thresh52, and Termination condition: M1-Hys51>Thresh51 and / or M2+Of2+Oc2+Hys52 <Thresh52、ただし、 M1 indicates the probability that the first cell will function as the target cell. M2 indicates the probability that the second cell will function as the target cell. Of2 represents the first offset of the probability that the second cell will function as the target cell. Oc2 represents the second offset of the probability that the second cell will function as the target cell. Hys51 represents the first hysteresis parameter of event 5. Hys52 represents the second hysteresis parameter of event 5. Thresh51 indicates the first threshold for event 5. Thresh52 indicates the second threshold for event 5.

[0039] In Event 5, more parameters such as Of2, Oc2, Hys51, and Hys52 are referenced, which makes the decision for Event 5 more accurate, flexible, and stable.

[0040] In a possible design, configuration 1 is used to constitute at least one of events 6 and 7, where the probability includes the probability that the second cell functions as the target cell, and the second cell is the cell in the first set of cells that has the highest probability of being the target cell. Events 6 and 7 are described as follows:

[0041] Event 6: The probability that the second cell functions as the target cell is greater than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting conditions: M2>Mx+Off, and Termination condition: M2 <Mx+Off、ただし、 M2 indicates the probability that the second cell will function as the target cell. Mx represents the probability that the third cell functions as the target cell, and the third cell is any cell in the first set of cells other than the second cell. "Off" indicates the offset value for event 6.

[0042] For example, the second cell could be the first cell. Correspondingly, event 6 could be used to determine that a cell handover is not temporarily required. In other words, there is a high probability that the first cell will function as the target cell, and the first terminal device does not need to perform a cell handover.

[0043] In another example, the second cell is a cell in the first cell set other than the first cell. Correspondingly, event 6 may be used to initiate a handover. In other words, there is a high probability that at least one cell other than the first cell will function as the target cell. In this case, the first terminal device may send probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates a cell handover. This helps reduce cell handover delays.

[0044] Event 7: The probability that the second cell functions as the target cell is less than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting condition: M2 <Mx+Off、および Termination condition: M2 > Mx + Off, however, M2 indicates the probability that the second cell will function as the target cell. Mx represents the probability that the third cell functions as the target cell, and the third cell is any cell in the first set of cells other than the second cell. "Off" indicates the offset value for event 7.

[0045] In other words, with respect to probability, there is no cell with a high probability of being the target cell, making it difficult to decide whether to perform a cell handover or to determine the target cell. Therefore, for example, the first terminal device may interrupt the execution of target cell probability inference in order to reduce the terminal's power consumption.

[0046] In a possible design, configuration 1 is used to constitute at least one of events 6 and 7, where the probability includes the probability that the second cell functions as the target cell, and the second cell is the cell in the first set of cells that has the highest probability of being the target cell. Events 6 and 7 are described as follows:

[0047] Event 6: The probability that the second cell functions as the target cell is greater than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting conditions: M2+Of2+Oc2-Hys>Mx+Ofx+Ocx+Off, and Termination condition: M2+Of2+Oc2+Hys <Mx+Ofx+Ocx+Off、ただし、 M2 indicates the probability that the second cell will function as the target cell. Mx represents the probability that the third cell functions as the target cell, and the third cell is any cell in the first set of cells other than the second cell. Of2 represents the first offset of the probability that the second cell will function as the target cell. Oc2 represents the second offset of the probability that the second cell will function as the target cell. Ofx represents the first offset of the probability that the third cell will function as the target cell. Ocx represents the second offset of the probability that the third cell will function as the target cell. Hys shows the hysteresis parameters for event 6. "Off" indicates the offset value for event 6.

[0048] Event 6 references more parameters such as Of2, Oc2, Ofx, Ocx, and Hys, which makes the decision for Event 6 more accurate, flexible, and stable.

[0049] Event 7: The probability that the second cell functions as the target cell is less than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting conditions: M2+Of2+Oc2+Hys <Mx+Ofx+Ocx+Off、および Termination condition: M2 + Of2 + Oc2 - Hys > Mx + Ofx + Ocx + Off, however, M2 indicates the probability that the second cell will function as the target cell. Mx represents the probability that the third cell functions as the target cell, and the third cell is any cell in the first set of cells other than the second cell. Of2 represents the first offset of the probability that the second cell will function as the target cell. Oc2 represents the second offset of the probability that the second cell will function as the target cell. Ofx represents the first offset of the probability that the third cell will function as the target cell. Ocx represents the second offset of the probability that the third cell will function as the target cell. Hys shows the hysteresis parameter for event 7. "Off" indicates the offset value for event 7.

[0050] Event 7 references more parameters such as Of2, Oc2, Ofx, Ocx, and Hys, which makes the decision for Event 7 more accurate, flexible, and stable.

[0051] In a possible design, configuration 1 is used to constitute at least one of events 8 and 9, where the probability includes the probability that the second cell acts as the target cell. Events 8 and 9 are described as follows:

[0052] Event 8: The sum of the probabilities of k cells that have a higher probability of being the target cell is greater than the threshold. Starting conditions:

number

number

[0053] For example, event 8 could be used to initiate another AI / ML model to comprehensively determine the target cell.

[0054] Specifically, the first terminal device starts AI / ML model 1, uses AI / ML model 1 to roughly estimate the probability that each of the N cells will function as a target cell, and then uses the first k cells with the higher probability among the N cells to determine event 8.

[0055] When the initiation condition for event 8 is met, AI / ML model 2 is started, and using AI / ML model 2, the probability that each of the aforementioned k cells will function as a target cell is accurately estimated, and then the target cell is determined based on the accurately estimated probability. During accurate estimation, AI / ML model 2 is started only when event 8 is met, and accurate estimation is performed only for k cells instead of for N cells. This helps reduce the operating energy consumption on the terminal device side and can further guarantee the accuracy of the target cell.

[0056] Event 9: The sum of the probabilities of k cells that have a higher probability of being the target cell is less than the threshold. Starting conditions:

number

number

[0057] For example, event 9 can be used to temporarily halt the inference of an AI / ML model.

[0058] Specifically, the first terminal device starts AI / ML model 1, uses AI / ML model 1 to roughly estimate the probability that each of the N cells will function as a target cell, and then uses the first k cells with the highest probability among the N cells to determine event 9. If the conditions for initiating event 9 are met, the inference using AI / ML model 1 is temporarily suspended to help reduce the operating energy consumption on the terminal device side.

[0059] In a possible design, configuration 1 is used to constitute at least one of events 8 and 9, where the probability includes the probability that the second cell acts as the target cell. Events 8 and 9 are described as follows:

[0060] Event 8: The sum of the probabilities of k cells that have a higher probability of being the target cell is greater than the threshold. Starting conditions:

number

number

[0061] In Event 8, the hysteresis parameter Hys is referenced further, which makes the decision for Event 8 more stable.

[0062] Event 9: The sum of the probabilities of k cells that have a higher probability of being the target cell is less than the threshold. Starting conditions:

number

number

[0063] In Event 9, the hysteresis parameter Hys is further referenced, which makes the decision for Event 9 more stable.

[0064] In a possible design, configuration 1 is used to constitute at least one of event 10 and event 11, where the probabilities include the probability of a cell handover. Events 10 and 11 are described below.

[0065] Event 10: The probability of cell handover is greater than the threshold. Starting conditions: P > Thresh, and Termination condition: P <Thresh、ただし、 P represents the probability of a cell handover, and Thresh represents the threshold corresponding to event 10.

[0066] For example, event 10 could be used to initiate a handover. In other words, there is a high need to perform a cell handover, and the first terminal device can perform the cell handover.

[0067] In another example, event 10 may be used further to initiate another event or AI / ML model to precisely determine the target cell. Specifically, the AI / ML model for event 10 may be simple, while the AI / ML model for precisely determining the target cell may be complex and have high power consumption. The AI / ML model for precisely determining the target cell is initiated only when event 10 is met, thereby reducing the terminal's power consumption.

[0068] Event 11: The probability of cell handover is less than the threshold. Starting condition: P <Thresh、および Termination condition: P > Thresh, however, P represents the probability of a cell handover, and Thresh represents the threshold corresponding to event 11.

[0069] For example, event 11 may be used to temporarily suspend inference in the AI / ML model. Specifically, the first terminal device starts AI / ML model 1, uses AI / ML model 1 to estimate the probability P of a cell handover, and then uses the probability P of a cell handover to determine event 11. If the conditions for initiating event 11 are met, inference using AI / ML model 1 is temporarily suspended to help reduce the operating energy consumption on the terminal device side.

[0070] In a possible design, configuration 1 is used to constitute at least one of event 10 and event 11, where the probabilities include the probability of a cell handover. Events 10 and 11 are described below.

[0071] Event 10: The probability of cell handover is greater than the threshold. Starting conditions: P-Hys>Thresh, and Termination condition: P+Hys <Thresh、ただし、 P represents the probability of cell handover, and Thresh represents the threshold corresponding to event 10. Hys represents the hysteresis parameter for event 10.

[0072] In event 10, the hysteresis parameter Hys is further referenced, which makes the decision for event 10 more stable.

[0073] Event 11: The probability of cell handover is less than the threshold. Starting condition: P+Hys <Thresh、および Termination condition: P-Hys > Thresh, however, P represents the probability of cell handover, and Thresh represents the threshold corresponding to event 11. Hys represents the hysteresis parameter for event 11.

[0074] In event 11, the hysteresis parameter Hys is further referenced, which makes the decision for event 11 more stable.

[0075] In a possible design, after determining the configuration information, the method further includes the first terminal device sending second information to the first network device, the second information including an identifier for at least one cell and / or an event identifier that triggers the second information, the at least one cell being one or more of the cells satisfying configuration 1, and the event identifier being one or more of the events of configuration 1.

[0076] In other words, the first terminal device provides the first network device with second information, which the first network device uses to determine the target cell. The target cell is determined based on the identifier of at least one cell and / or an event identifier that triggers the second information, making the prediction of the target cell more accurate, which helps improve the accuracy and success rate of cell handovers.

[0077] In a possible design, the second piece of information further includes probabilistic information, which includes the probability that the cell indicated by the second piece of information will function as a target cell, thereby allowing the first network device to determine the target cell based on the probabilistic information. In this way, the prediction of the target cell becomes more accurate, which helps improve the accuracy and success rate of cell handover.

[0078] In a possible design, when configuration information is used to configure configuration 2, the method further includes the first terminal device sending first information to a first network device, the first information being used to determine cell handover, and / or the first information being used to determine a target cell.

[0079] The first information is information provided to the first network device by the first terminal device. Therefore, cell handover decisions and target cell determinations are performed by the first network device, which allows the first network device to make decisions by referring to more information. For example, in addition to the first information, the first network device may further make decisions by referring to network-side information (e.g., load status of each cell) to help improve the accuracy and success rate of cell handovers.

[0080] In a possible design, the first piece of information is as follows: Item 1: Measured quantity acquired by the first terminal device through measurement, Second item: Channel status information CSI determined by the first terminal device, and Third item: One or more of the following from the location information, motion information, and service information of the first terminal device. It relates to at least one of the following.

[0081] In a possible design, when configuration information is used to configure configuration 3, the configuration information is further used to configure a second time period, the measurement of the second time period is used to predict the measurement of configuration 3, and the measurement of the second time period is obtained by a first terminal device through measurement.

[0082] For example, when configuration 3 is used to configure an event related to a measurement at a first time point, the measurement in configuration 3 includes the measurement at the first time point.

[0083] In another example, configuration 3 is used to configure an event related to a quantifier in a first time period, and the quantifier in configuration 3 includes the quantifier in the first time period.

[0084] In other words, the first network device may further configure a second time period, thereby allowing the first terminal device to determine the measurement at the first time point or the measurement for the first time period based on the measurement of the second time period.

[0085] In a possible design, after determining the configuration information, the method further includes the first terminal device sending third information to the first network device, the third information including an identifier for at least one cell and / or a measurement identifier that triggers the third information, the at least one cell being one or more cells satisfying configuration 3, the measurement identifier identifying at least one meter and / or at least one event, and each measurement result of the at least one meter being one of the meter quantities of configuration 3. In this case, the measurement identifier may include a meter identifier, and the meter identifier identifies the meter.

[0086] Each of at least one event is one event configured using configuration 3.

[0087] In other words, the first terminal device provides the first network device with third information, which the first network device uses to determine the target cell. The target cell is determined based on the identifier of at least one cell and / or a measurement identifier that triggers the third information, and the prediction of the target cell is more accurate, which helps improve the accuracy and success rate of cell handover.

[0088] In a possible design, when the third piece of information includes the identifier of at least one cell, the third piece of information further includes a metric of the cell indicated by the third piece of information at a first point in time or a first time period, thereby allowing the first network device to determine the target cell based on the metric in the third piece of information. In this way, the prediction of the target cell becomes more accurate, which helps to improve the accuracy and success rate of cell handover.

[0089] In a possible design, the quantifier corresponding to the measured quantity includes at least one of the following: reference signal received power RSRP, reference signal received quality RSRQ, or signal-to-interference noise ratio SINR.

For the sake of clarity, the following uses a network device as an example for illustrative purposes.

[0119] Optionally, terminal devices access the core network via network devices. Terminal devices include devices that provide voice and / or data connectivity to users. Specifically, terminal devices include devices that provide voice to users, devices that provide data connectivity to users, or devices that provide both voice and data connectivity to users. For example, terminal devices may include handheld devices with wireless connectivity or processing devices connected to wireless modems. Terminal devices may communicate with the core network via a wireless access network and exchange voice or data with the RAN, or voice and data with the RAN. Terminal devices may include user equipment (UE), wireless terminal devices, mobile terminal devices, D2D terminal devices, V2X terminal devices, machine-to-machine / machine-type communication (M2M / MTC) terminal devices, Internet of Things (IoT) terminal devices, subscriber units, subscriber stations, mobile stations, remote stations, access points (AP), remote terminals, access terminals, user terminals, user agents, or user devices.

For example, a terminal device may include an information sensing device, such as a barcode, radio frequency identification (RFID), a sensor, a global positioning system (GPS), or a laser scanner.

[0120] When the various terminal devices described above are deployed in a vehicle (for example, placed in or mounted on the vehicle), all terminal devices may be considered in-vehicle terminal devices. For example, in-vehicle terminal devices are also called on-board units (OBUs).

[0121] In embodiments of this application, the terminal device may further include a relay. Alternatively, it is understood that any device capable of performing data communication with a base station may be considered a terminal device.

[0122] In embodiments of this application, the device configured to perform the functions of a terminal device may be a terminal device, or it may be a device capable of supporting the terminal device in performing those functions, such as a chip system. This device may be mounted on the terminal device. In embodiments of this application, the chip system may include a chip, or it may include a chip and another discrete device. In the technical solutions provided in embodiments of this application, an example is used in the description in which the device configured to perform the functions of a terminal is a terminal device.

[0123] It should be understood that network devices and terminal devices may be in a fixed location or may be mobile. Network devices and terminal devices may be located on land (in which case the location may include indoor or outdoor, or handheld or vehicle-mounted locations), on water, or in the air on aircraft, balloons, and satellites. The application scenarios for network devices and terminal devices are not limited in the embodiments of this application.

[0124] The roles of network devices and terminal devices can be relative. For example, the helicopter or unmanned aerial vehicle 120i in Figure 1 can be configured as a mobile base station. Terminal device 120i is a network device with respect to terminal device 120j, which accesses the radio access network via 120i. However, 120i is a terminal device with respect to network device 110a. In other words, 110a and 120i communicate with each other using the Wireless Air Interface Protocol. Of course, 110a and 120i may also communicate with each other using the Inter-Base Station Interface Protocol. In this case, 120i is also a network device with respect to 110a. Therefore, network devices and terminal devices can be collectively called communication devices. 110a and 110b in Figure 1 can each be called communication devices with network device functionality, and 120a to 120j in Figure 1 can each be called communication devices with terminal device functionality.

[0125] Communication may be performed over authorized spectrum between network devices and terminal devices, between network devices, and between terminal devices, over unauthorized spectrum, or over both authorized and unauthorized spectrum. Communication may be performed over spectrum below 6 gigahertz (GHz), over spectrum above 6 GHz, or over both spectrum below 6 GHz and spectrum above 6 GHz. The spectral resources used for wireless communication are not limited in the embodiments of this application.

[0126] In embodiments of this application, the functions of a network device may be performed by a module (e.g., a chip) within the network device, or by a control subsystem that includes the functions of the network device. The control subsystem that includes the functions of the network device may be a control center in application scenarios such as smart grids, industrial control, smart transportation, and smart cities. Alternatively, the functions of a terminal device may be performed by a module (e.g., a chip or modem) within the terminal device, or by a device that includes the functions of the terminal device.

[0127] In the embodiments of this application, a network device sends downlink signals or downlink information to a terminal device, with the downlink information carried on a downlink channel. The terminal device sends uplink signals or uplink information to the network device, with the uplink information carried on an uplink channel. To communicate with the network device, the terminal device needs to establish a wireless connection to a cell controlled by the network device. The cell with which the terminal device establishes a wireless connection is called the terminal device's serving cell. When communicating with the serving cell, the terminal device is further affected by signal interference from neighboring cells.

[0128] It should be noted that the solutions in the embodiments of this application may also be applied to other communication systems, and the corresponding names may be replaced with the names of the corresponding functions in the other communication systems.

[0129] To facilitate understanding of the embodiments of this application, the following is a brief explanation of the terminology used in the embodiments. It should be understood that this explanation is intended solely to facilitate understanding of the embodiments and does not constitute any limitation to this application.

[0130] 1. Handover: In wireless communication systems, when a terminal device moves from one cell to another, or due to network issues, service load balancing, or device failure, the terminal device may be handed over from the source cell to the target cell to ensure the continuity of communication between the terminal device and the network. The procedure described above is called "handover."

[0131] Cells accessed before a handover of a terminal device due to relocation, network issues, service load balancing, or device failure are described as source cells.

[0132] Cells accessed after a handover of terminal devices due to relocation, network issues, service load balancing, or device failure are described as target cells.

[0133] The source cell and target cell may be located on different physical devices, or they may be located on the same physical device.

[0134] Typically, handover procedures include normal handover (HO), conditional handover (CHO), and dual active protocol stack handover (DAPS HO).

[0135] In a possible design, Figure 2 illustrates the handover process. The process shown in Figure 2 includes the following actions:

[0136] S201: The first network device sends measurement and control information to the terminal device. In response, the terminal device receives measurement and control information from the first network device.

[0137] The first network device is a network device corresponding to a serving cell. For example, the first network device performs a measurement configuration using an RRC procedure. For example, the first network device sends RRC signaling to a terminal device, and the RRC signaling includes measurement control information.

[0138] Measurement control information includes information such as the measurement object, the measurement report (MR) configuration, and the measurement event.

[0139] The measurement target defines the target to be measured, including an identifier and specific configurations, such as the frequency and time-domain positions of the measurement target. The measurement target may include one or more of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), or signal-to-interference plus noise ratio (SINR). The measurement / prediction result of the measurement target may be called the measured quantity, e.g., RSRP value, RSRQ value, or SINR value.

[0140] It should be noted that in the embodiments of this application, the measured quantity includes at least one of the following:

[0141] Item 1: Measured quantities obtained by a terminal device through measurement. In other words, the measurement results obtained by a terminal device by measuring the object to be measured are called measured quantities, for example, measured quantities obtained by a terminal device by performing a measurement based on measurement control information after the terminal device receives measurement control information, for example, the RSRP value obtained by measuring RSRP, the RSRQ value obtained by measuring RSRQ, or the SINR value obtained by measuring SINR.

[0142] The second item: Measured quantities obtained by the terminal device through prediction. In other words, the prediction results obtained by the terminal device by predicting the object to be measured are called measured quantities, for example, measured quantities obtained by the terminal device by performing a prediction based on the measurement control information after the terminal device has received the measurement control information, for example, the RSRP value obtained by predicting the RSRP, the RSRQ value obtained by predicting the RSRQ, or the SINR value obtained by predicting the SINR. Predictions performed by the terminal device may include predictions performed based on an AI / ML model or predictions performed in other ways. This is not limited to the embodiments of this application.

[0143] In embodiments of this application, the measurement obtained by the terminal device through prediction may be described as a future measurement, for example, a measurement at a future point in time or a measurement over a future period of time. For details, please refer to the description of Configuration 3, which is not described here.

[0144] The measurement report configuration defines the configurations related to measurement reporting, including the reporting evaluation criteria for measurement reports, such as whether measurement reports are event-triggered or reported periodically.

[0145] Measurement events define the events that trigger the reporting of measurement reports and the thresholds corresponding to those measurement events.

[0146] Measurement and control information may consist of the same message or different messages.

[0147] For example, a measurement event may be at least one of the following: Event A1, Event A2, Event A3, Event A4, Event A5, Event A6, Event B1, or Event B2. The threshold corresponding to a measurement event is a reference value for determining whether the event has started or ended. The specific value of the threshold is determined by the network based on past experience.

[0148] For example, a timer is triggered when an event starts and stopped when the event ends. TTT indicates the period of time during which the event start condition is continuously met, i.e., the trigger duration, which may be configured by the network side or agreed upon in advance.

[0149] In another example, a counter is triggered when an event starts and stopped when the event ends. NTT indicates the number of consecutive times the event start condition is met, i.e., the number of triggers, which may be configured by the network side or agreed upon in advance.

[0150] The following describes the measurement events and their corresponding thresholds.

[0151] Event A1 indicates that the measured quantity of the serving cell is greater than a preset threshold. The threshold is assumed to be Thresh. When inequality A1-1 is satisfied, event A1 is initiated, and when inequality A1-2 is satisfied, event A1 is terminated.

Assume the first threshold is ThreshA51 and the second threshold is ThreshA52. Event A5 begins when inequalities A5-1 and A5-2 are satisfied, the order of the two starting conditions is not restricted, and event A5 ends when at least one of inequalities A5-3 or A5-4 is satisfied. Inequality A5-1 (starting condition 1): Mp+Hys <ThreshA51、 Inequality A5-2 (starting condition 2): Mn+Ofn+Ocn-Hys>ThreshA52, Inequality A5-3 (termination condition 1): Mp - Hys > Thresh A51, and Inequality A5-4 (Termination Condition 2): Mn + Ofn + Ocn + Hys <ThreshA52、ただし、 Mp is a measurement for a specific cell, Mn is a measurement for an adjacent cell, Ofn is the frequency offset of the adjacent cell (this may be replaced by a frequency point or frequency band), Ocn is the cell-specific offset of the adjacent cell, Hys is the event hysteresis parameter, and Ofn, Ocn, Hys, ThreshA51, and ThreshA52 may be configured by the network side.

Inequality A6-1 (starting condition): Mn + Ocn - Hys > Ms + Ocs + Off, and Inequality A6-2 (termination condition): Mn + Ocn + Hys <Ms+Ocs+Off、ただし、 Ms is the measured value of the serving cell, Mn is the measured value of the adjacent cell, Ocn is the cell-specific offset of the adjacent cell, Ocs is the cell-specific offset of the serving cell, Hys is the event hysteresis parameter, and Off is the event offset parameter. Mn and Ms are obtained in the measurement procedure, and the other parameters are configured by the network.

[0157] Event B1 indicates that the measured value of an adjacent cell between wireless access technologies is greater than a preset threshold. The threshold is assumed to be Thresh.

[0159] Note that a start condition is a condition that must be met for an event to begin. Additionally, note the following: start conditions and trigger conditions have the same meaning and can be used interchangeably. The following uses a start condition as an example for explanation.

[0160] Similarly, termination conditions are the conditions that must be met for an event to end. Furthermore, note the following: termination conditions and expiration conditions have the same meaning and can be used interchangeably.

Additionally, the following terms—start event, trigger event, execute event, and fulfillment event—have the same meaning and can be used interchangeably. The following example uses a start event for illustrative purposes.

[0162] Similarly, if the described termination condition is met, it means the event has ended. In addition, the following terms—termination event, expiration event, non-performance event, and unsatisfied event—have the same meaning and can be used interchangeably.

[0163] Regarding the terminal device, after receiving measurement and control information, the terminal device executes S202.

[0165] For example, a terminal device monitors a radio channel based on the object to be measured, as indicated by measurement control information, and performs measurements at, for example, specific frequency positions and specific time-domain positions to obtain measurement results, i.e., measured quantities.

[0166] When the measurement result satisfies the measurement event, the terminal device executes S203.

[0167] S203: The terminal device sends a measurement report to the first network device. In response, the first network device receives the measurement report from the terminal device.

[0168] For example, a measurement report may include the measurement results for a serving cell and / or the measurement report may include the measurement results for the serving cell's adjacent cells. A serving cell may have one or more adjacent cells.

[0169] S204: The first network device determines the target cell based on the measurement report.

[0170] For example, the first network device selects one cell as a target cell from at least one cell in the measurement report based on radio resource management (RRM) information, and uses, for example, the cell with the best measurement result as the target cell.

[0171] S205: The first network device notifies the second network device to perform handover preparations.

[0172] The second network device is a network device corresponding to the target cell. The second network device and the first network device are the same physical device, but may provide different cell services, or they may be different physical devices.

[0173] For example, the first network device sends a handover readiness request to the second network device. In response, the second network device receives a handover readiness request from the first network device.

[0174] A handover preparation request is used to request a second network device to prepare resources for the terminal device, such as terminal access resources.

[0175] S206: The terminal device, the first network device, and the second network device perform a handover.

[0176] For example, in the case of a second network device, after receiving a handover readiness request, the second network device decides whether to establish a connection to the terminal device based on its current status, and if so, performs the following actions:

[0177] The second network device sends a handover readiness request acknowledgment (ACK) to the first network device. In response, the first network device receives the handover readiness request acknowledgment from the second network device.

[0178] The first network device sends a handover command to the terminal device. In response, the terminal device receives a handover command from the first network device. The handover command includes configuration information for the target cell.

[0179] The terminal device disconnects from the first network device in accordance with the handover command. In response, the first network device also disconnects from the terminal device.

[0180] The terminal device initiates a random access channel (RACH) procedure to the second network device corresponding to the target cell, in accordance with the handover command. In response, the second network device corresponding to the target cell and the terminal device execute the RACH procedure.

[0181] However, in the processing method shown in Figure 2, the target cell is determined by the first network device and selected based on measurement reports reported by terminal devices. Due to the complexity and variability of the radio channel, the measurement report represents the measurement results of the radio channel over a configured time period (e.g., a time period corresponding to TTT), and lacks predictability and foresight. When the channel quality of the target cell is low, radio link failure (RLF) or ping-pong handover may occur.

[0182] In another possible design, the terminal device predicts the target cell based on an artificial intelligence (AI) / machine learning (ML) model. For example, the input information for the AI / ML model includes a quantifier of the terminal device, e.g., a quantifier of at least one cell, and the output information for the AI / ML model indicates the target cell. Based on the AI / ML model, the cell with the highest probability among at least one cell functions as the target cell. The highest probability can be understood as the highest probability among the probabilities of at least one cell, each of which is the target cell.

[0183] While AI / ML models possess strong predictive capabilities, better handover performance, such as reduced ping-pong handovers and RLFs, can be achieved to some extent. However, in procedures that predict target cells based on AI / ML models, the cell with the highest probability is simply selected as the target cell. Probability information for using a different cell as the target cell is lost, and the problem of inaccurate prediction of the target cell can still exist.

[0184] In conclusion, the cell handover procedure has problems with low accuracy in handing over to the target cell and a high probability of handover failure.

[0185] With this in mind, embodiments of this application provide a handover configuration method. This method may be applied to the communication system shown in Figure 1. The method includes a first terminal device receiving downlink signaling from a first network device in a first cell and determining configuration information based on the downlink signaling, the configuration information being: Configuration 1: An event related to probability, the probability includes the probability of a cell handover or the probability that a second cell functions as a target cell, the second cell belongs to a first cell set, and the first cell set includes: a first cell (if the first cell is a cell group, the first cell set may include at least one cell within the cell group), at least one inter-radio access technology (Inter RAT) adjacent cell of the first cell, In configuration 1, when the target cell is different from the first cell, the target cell is the cell accessed by the first terminal device after the first terminal device performs a cell handover, and a cell handover is an operation that can be performed by the first terminal device, or when the target cell overlaps with the first cell, it means that the first terminal device cannot perform a cell handover, event, Configuration 2: Determining the first information based on the first submodel, where the first submodel is part of the following models: an AI model or an ML model, and the first information is used for cell handover. Configuration 3: An event relating to a quantifiable quantity at a first point in time or a quantifiable quantity during a first time period, wherein the first point in time includes a future point in time, the first time period includes a future time period, and the quantifiable quantity at the first point in time or the quantifiable quantity during the first time period is acquired by a first terminal device through prediction, the event Show at least one of them.

[0186] In configuration 3, the predicted result of the measured object can also be called the measured quantity without causing confusion.

[0187] In other words, the first network device uses configuration information to configure one or more configurations for the first terminal device, such as configuration 1, configuration 2, or configuration 3, in order to optimize the cell handover-related configuration.

[0188] Specifically, in Configuration 1, the events in Configuration 1 are related to probability and are predictive and predictive. For example, the probability that the first cell functions as a target cell can represent the confidence level that the first cell functions as a target cell. The probability of a cell handover can represent the need to perform a cell handover.

[0189] In configuration 2, the first information is obtained by performing a process that uses the first submodel. Since the first submodel is part of the AI / ML model, the first information does not indicate the target cell, but it is used for cell handover.

[0190] In configuration 3, the events of configuration 3 relate to a metric at a future point in time or over a future period of time, and are also predictive and forward-looking.

[0191] With respect to the events defined in Configuration 1 and Configuration 3, other parameters such as thresholds and offset values ​​corresponding to the events are also referenced. Similarly, in Configuration 2, after the first terminal device determines the first information based on the first submodel, the first network device decides whether to perform a cell handover based on the first information, or based on the first information and network-side reference information (e.g., load status of each cell), or determines the target cell based on the first information and network-side reference information. Compared to determining the target cell based only on a measured quantity of the configured time period, or simply selecting the cell with the highest probability as the target cell, the optimized configuration of this application allows the communication device to refer to more information to predict whether to perform a cell handover or determine the target cell, in order to help improve the accuracy and success rate of the handover.

[0192] In the following embodiments of this application, the names of messages between devices or the names of each parameter within a message are merely examples and may be different in specific embodiments. This is not specifically limited to the embodiments of this application.

[0193] Referring to Figures 3 to 5, the handover configuration method provided in the embodiments of this application will be described in detail below. The handover configuration method 300 provided in one embodiment of this application includes the following operations.

[0194] S301: The first network device determines the configuration information.

[0195] For example, the first network device is the network device corresponding to the source cell of the first terminal device, that is, the network device that the first terminal device was accessing before the first terminal device performed a cell handover.

[0196] The configuration information indicates one or more of the measurement configurations, for example, configuration 1, configuration 2, and configuration 3. For details, please refer to the explanation from S303 onwards. Details are not explained here.

[0197] S302: The first network device sends downlink signaling to the first terminal device in the first cell. In response, the first terminal device receives downlink signaling from the first network device in the first cell.

[0198] The first cell is the cell that the first terminal device is accessing before the first terminal device performs a cell handover.

[0199] In the embodiments of this application, the first cell may be a single cell or a group of cells.

[0200] For example, in different scenarios, the first cell may be one of the following, or contain at least one of the following:

[0201] 1. Primary cell (PCell): Also known as a master cell group (MCG) cell. It operates at the primary frequency, where the first terminal device performs the initial connection establishment procedure or initiates the connection re-establishment procedure.

[0202] The relevant technical specifications are described below. PCell:The MCG(Master Cell Group)cell,operating on the primary frequency,in which the UE either performs the initial connection establishment initiate procedure ors the connection re-establishment procedure.

[0203] 2. Primary Secondary Cell Group Cell (PSCell): This can be understood as a secondary cell group (SCG) cell in which the first terminal device performs random access when performing a Reconfiguration with Sync procedure with respect to the first terminal device configured with dual connectivity (DC).

[0204] The relevant technical specifications are described below. For a dual connectivity operation, the SCG cell in which the UE performs random access when performing the Reconfiguration with Sync procedure.

[0205] 3. Secondary cell (SCell): This can be understood as a cell that provides additional radio resources on top of a special cell (SpCell) with respect to a first terminal device consisting of carrier aggregation (CA). For details of a special cell in the embodiments of this application, please refer to the following description in Section 5. Details are not provided here.

[0206] The relevant technical specifications are described below. SCell:For a UE configured with CA,a cell providing additional radio resources on top of Special Cell.

[0207] 4. Serving cell: For a first terminal device in RRC_CONNECTED mode that is not configured with a CA / DC, there is only one serving cell, which includes the primary cell. For a first terminal device in RRC_CONNECTED mode that is configured with a CA / DC, the serving cell may be understood to represent a set of cells including a special cell and all secondary cells.

[0208] The relevant technical specifications are described below. Serving Cell: For a UE in RRC_CONNECTED not configured with CA / DC, there is only one serving cell, which is the primary cell. For a UE in RRC_CONNECTED configured with CA / DC, the term ’serving cells’ is used to denote the set of cells including the Special Cell(s) and all secondary cells.

[0209] 5. Special Cell: For a first terminal device configured with dual connectivity, it can be understood that the SpCell is the PCell of the MCG or the PSCell of the SCG. If dual connectivity is not configured, the SpCell refers to the PCell.

[0210] The description of the related technical specifications is as follows. Special Cell (SpCell): For a Dual Connectivity operation, the term Special Cell refers to the PCell of the MCG or the PSCell of the SCG; otherwise, the term Special Cell refers to the PCell.

[0211] Downlink signaling includes configuration information. The configuration information may be configured using one signaling or multiple signals.

[0212] For example, downlink signaling is RRC signaling, such as RRC Reconfiguration. In other words, the first network device performs measurement configuration in the RRC procedure.

[0213] For example, in the first network device, in the first cell, it sends RRCReconfiguration to the first terminal device. Correspondingly, the first terminal device receives RRCReconfiguration from the first network device. RRCReconfiguration contains configuration information. After the first terminal device successfully receives RRCReconfiguration, the first terminal device sends RRC Reconfiguration Complete (RRCReconfiguration complete) to the first network device. Correspondingly, the first network device receives RRCReconfiguration complete from the first terminal device.

[0214] S303: The first terminal device determines configuration information based on downlink signaling.

[0215] For example, the downlink signaling is RRC signaling. The first terminal device obtains configuration information from the RRC signaling.

[0216] In S301 - S303, the description of the configuration information is as follows.

[0217] The configuration information is as follows: Configuration 1: An event related to probability, where the probability includes the probability of cell handover or the probability that the second cell functions as a target cell. The second cell belongs to the first cell set, and the first cell set includes at least one of the following: the first cell, at least one in - band adjacent cell of the first cell in the same radio access technology, or at least one inter - band adjacent cell of the first cell in different radio access technologies. When the second cell is different from the first cell, the target cell is the cell accessed by the first terminal device after the first terminal device performs a cell handover. Cell handover is an operation that can be performed by the first terminal device. Or when the second cell overlaps with the first cell, it means that the first terminal device cannot perform a cell handover. An event. Configuration 2: Determining the first information based on the first submodel, where the first submodel is part of the following models: an AI model or an ML model, and the first information is used for cell handover. Configuration 3: An event relating to a quantifiable quantity at a first point in time or a quantifiable quantity during a first time period, wherein the first point in time includes a future point in time, the first time period includes a future time period, and the quantifiable quantity at the first point in time or the quantifiable quantity during the first time period is acquired by a first terminal device through prediction, the event Show at least one of them.

[0218] Next, the events of Configuration 1 will be described in detail.

[0219] Event 1: The probability that the first cell functions as a target cell is greater than the threshold. Starting conditions: M1>Thresh, and Termination condition: M1 <Thresh、ただし、 M1 indicates the probability that the first cell will function as the target cell, and Thresh indicates the threshold for event 1.

[0220] In Event 1, the first cell is the same as the second cell. For details about the first cell, please refer to the explanation in S302. Further details will not be explained here.

[0221] For example, in a possible embodiment, event 1 is used to stop inter-frequency / inter-radio access technology measurements. In other words, there is a high probability that the first cell will act as a target cell, and the first terminal device may stop measurements, such as inter-frequency / inter-radio access technology measurements, in order to reduce the terminal's power consumption.

[0222] In some embodiments, event 1 may further have the following forms:

[0223] The conditions for Event 1 are: Starting conditions: M1-Hys>Thresh, and Termination condition: M1+Hys <Thresh This includes, however, M1 represents the probability that the first cell will function as the target cell, Thresh represents the threshold for event 1, and Hys represents the hysteresis parameter for event 1, which makes the decision for event 1 more stable.

[0224] In Event 1, it should be understood that M1 is determined by the first terminal device. The Thresh and Hys parameters may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0225] Event 2: The probability that the first cell functions as a target cell is less than the threshold. Starting condition: M1 <Thresh、および Termination condition: M1 > Thresh, however, M1 indicates the probability that the first cell will function as the target cell, and Thresh indicates the threshold for event 2.

[0226] In Event 2, it is easy to understand that the first cell is the same as the second cell. For details about the first cell, please refer to the explanation in S302. Further details will not be explained here.

[0227] For example, in a possible embodiment, Event 2 is used to initiate inter-frequency / inter-radio access technology measurements. In other words, there is a low probability that the first cell functions as a target cell and the first terminal device may initiate measurements, such as inter-frequency / inter-radio access technology measurements. When the measurement amount of the inter-frequency / inter-radio access technology measurements is used for cell handover (e.g., used to determine whether to perform cell handover and / or used to determine the target cell to be accessed by the first terminal device after cell handover), the inter-frequency / inter-radio access technology measurements are initiated in a timely manner. This helps to reduce unnecessary delays in cell handover.

[0228] In some embodiments, Event 2 may further have the following form.

[0229] The conditions for Event 2 are Start condition: M1 + Hys < Thresh, and End condition: M1 - Hys > Thresh where, M1 represents the probability that the first cell functions as a target cell, Thresh represents the threshold of Event 2, and Hys represents the hysteresis parameter of Event 2, whereby the determination of Event 2 is more stable.

[0230] It should be understood that in Event 2, M1 is determined by the first terminal device. Each parameter of Thresh and Hys may be configured by the network side, agreed upon by two communicators, or determined by the first terminal device. This is not limited in the embodiments of this application

[0231] Event 3: The probability that the second cell functions as a target cell is greater than the probability that the first cell functions as a target cell, Start condition: M2 > M1, and End condition: M2 < M1, where, M2 represents the probability that the second cell functions as the target cell, and M1 represents the probability that the first cell functions as the target cell.

[0232] It is easy to understand that the first cell is different from the second cell.

[0233] Possible embodiments: In Event 3, the second cell is at least one intra-radio access technology adjacent cell of the first cell, for example, an intra-frequency adjacent cell or an inter-frequency adjacent cell.

[0234] When the second cell is an in-frequency / inter-frequency adjacent cell of the first cell, it can be understood that event 3 indicates that the probability of the in-frequency / inter-frequency adjacent cell acting as the target cell is greater than the probability of the first cell acting as the target cell.

[0235] For example, in a possible embodiment, event 3 is used to initiate an in-frequency / inter-frequency handover. In other words, there is a high probability that an in-frequency / inter-frequency adjacent cell of the first cell will function as a target cell. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates a cell handover. For example, the first network device sends a handover preparation request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform a cell handover. See the description of Figure 2, for further details.

[0236] In possible embodiments, event 3 may be represented as event 31.

[0237] In some embodiments, event 31 may further have the following forms:

[0238] The conditions for Event 31 are: Starting conditions: M2+Of2+Oc2-Hys>M1+Of1+Oc1+Off, and Termination condition: M2+Of2+Oc2+Hys <M1+Of1+Oc1+Off This includes, however, M2 indicates the probability that the second cell functions as the target cell, M1 indicates the probability that the first cell functions as the target cell, and Off indicates the offset value of event 31. Of2 represents the first offset of the probability that the second cell functions as the target cell (the first offset may relate to frequency, frequency band, or frequency point), and Oc2 represents the second offset of the probability that the second cell functions as the target cell (the second offset may relate to the second cell). Of1 represents the first offset of the probability that the first cell functions as a target cell (the first offset may relate to frequency, frequency band, or frequency point), and Oc1 represents the second offset of the probability that the first cell functions as a target cell (the second offset may relate to the first cell). Hys represents the hysteresis parameter for event 31.

[0239] Event 31 references more parameters such as Of2, Oc2, Of1, Oc1, Hys, and Off, which makes the decision for Event 31 more accurate, flexible, and stable.

[0240] In Event 31, it should be understood that M1 and M2 are determined by the first terminal device. Each of the parameters such as Of2, Oc2, Of1, Oc1, Hys, and Off may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0241] In Event 31, parameters such as Of2, Oc2, Of1, Oc1, Hys, and Off are all optional parameters; in other words, only some of these parameters may be used in the expression of the start condition and / or the end condition. For example, a possible expression of the start condition is M2 + Of2 - Hys > M1 + Oc1 + Off. Many other possible expressions of the start or end condition can be inferred by analogy. Further details will not be explained again.

[0242] In another possible embodiment, event 3 may be represented as event 32.

[0243] The conditions for Event 32 are: Starting conditions: M2+Oc2-Hys>M1+Oc1+Off, and Termination condition: M2+Oc2+Hys <M1+Oc1+Off This includes, however, M2 indicates the probability that the second cell functions as the target cell, M1 indicates the probability that the first cell functions as the target cell, and Off indicates the offset value of event 32. Oc2 represents the offset of the probability that the second cell will function as the target cell, and Oc1 represents the offset of the probability that the first cell will function as the target cell. Hys represents the hysteresis parameter for event 32.

[0244] Event 32 references more parameters such as Oc2, Oc1, Hys, and Off, making the decision for Event 32 more accurate, flexible, and stable.

[0245] In Event 32, it should be understood that M1 and M2 are determined by the first terminal device. Each of the parameters such as Oc2, Oc1, Hys, and Off may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0246] In event 32, parameters such as Oc2, Oc1, Hys, and Off are all optional parameters; in other words, only some of the parameters may be used in the expressions of the start condition and / or end condition. This is not limited to the embodiments of this application.

[0247] Event 4: The probability that the second cell functions as a target cell is greater than the threshold. Starting conditions: M2>Thresh, and Termination condition: M2 <Thresh、ただし、 M2 indicates the probability that the second cell will function as the target cell, and Thresh indicates the threshold for event 4.

[0248] In possible embodiments, it can be understood that:

[0249] In Event 4, the second cell is at least one intra-radio access technology adjacent cell of the first cell, for example, an intra-frequency adjacent cell or an inter-frequency adjacent cell.

[0250] Event 4 can be understood as indicating that the probability of an in-frequency / inter-frequency adjacent cell acting as a target cell is greater than a certain threshold.

[0251] For example, in a possible embodiment, event 4 is used to initiate an in-frequency / inter-frequency handover. In other words, there is a high probability that an in-frequency / inter-frequency cell will function as a target cell. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates a cell handover. For example, the first network device sends a handover readiness request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform a cell handover. See the description of Figure 2, for further details.

[0252] Another possible embodiment: In Event 4, the second cell is at least one inter-radio access technology adjacent cell to the first cell.

[0253] Event 4 can be understood as indicating that the probability of an adjacent cell between wireless access technologies functioning as a target cell is greater than a certain threshold.

[0254] For example, in a possible embodiment, event 4 is used to initiate a handover between radio access technologies. In other words, there is a high probability that an adjacent cell between radio access technologies will function as a target cell. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates a cell handover. For example, the first network device sends a handover readiness request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform a cell handover. See the description of Figure 2, for further details.

[0255] In some embodiments, event 4 may further have the following forms:

Of2 represents the first offset of the probability that the second cell will function as the target cell (the first offset may relate to frequency, frequency band, or frequency point), Oc2 represents the second offset of the probability that the second cell will function as the target cell (the second offset may relate to the second cell), and Hys represents the hysteresis parameter of event 4.

[0257] In Event 4, more parameters such as Of2, Oc2, and Hys are referenced, which makes the decision for Event 4 more accurate, flexible, and stable.

[0258] In Event 4, it should be understood that M2 is determined by the first terminal device. Each of the parameters such as Thresh, Of2, Oc2, and Hys may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0259] In Event 4, parameters such as Of2, Oc2, and Hys are all optional parameters; in other words, only some of the parameters may be used in the expressions of the start condition and / or end condition. This is not limited to the embodiments of this application.

[0260] Event 5: The probability that the first cell functions as a target cell is less than the first threshold, and the probability that the second cell functions as a target cell is greater than the second threshold. Starting condition: M1<Thresh51かつM2> Thresh52, and Termination condition: M1 > Thresh51 and / or M2 <Thresh52、ただし、 M1 indicates the probability that the first cell will function as the target cell, and Thresh51 indicates the first threshold for event 5. M2 indicates the probability that the second cell will function as the target cell, and Thresh52 indicates the second threshold for event 5.

[0261] It is easy to understand that the first cell is different from the second cell.

[0262] Possible embodiments: In Event 5, the second cell is at least one radio access technology adjacent cell of the first cell, for example, an intra-frequency adjacent cell or an inter-frequency adjacent cell.

[0263] Event 5 can be understood as indicating that the probability of the first cell functioning as a target cell is less than a certain threshold (e.g., Thresh51), and the probability of an adjacent cell within the wireless access technology functioning as a target cell is greater than a certain threshold (e.g., Thresh52).

[0264] For example, event 5 is used to initiate a cell handover. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates the cell handover. For example, the first network device sends a handover preparation request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform the cell handover. See the explanation in Figure 2. Further details are not provided here.

[0265] Another possible embodiment: In Event 5, the second cell is at least one inter-radio access technology adjacent cell to the first cell.

[0266] Event 5 can be understood as indicating that the probability of the first cell functioning as a target cell is less than a certain threshold (e.g., Thresh51), and the probability of an inter-radio access technology adjacent cell functioning as a target cell is greater than a certain threshold (e.g., Thresh52).

[0267] For example, event 5 is used to initiate a cell handover. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates the cell handover. For example, the first network device sends a handover preparation request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform the cell handover. See the explanation in Figure 2. Further details are not provided here.

[0268] In some embodiments, event 5 takes the following form: Starting condition: M1+Hys51<Thresh51かつM2+Of2+Oc2-Hys52> Thresh52, and Termination condition: M1-Hys51>Thresh51 and / or M2+Of2+Oc2+Hys52 <Thresh52 It may also have, however, M1 indicates the probability that the first cell will function as the target cell, and Thresh51 indicates the first threshold for event 5. M2 indicates the probability that the second cell will function as the target cell, Thresh52 indicates the second threshold for event 5, and Thresh51 and Thresh52 may be the same or different. Of2 represents the first offset of the probability that the second cell functions as the target cell (the first offset may relate to frequency, frequency band, or frequency point), and Oc2 represents the second offset of the probability that the second cell functions as the target cell (the second offset may relate to the second cell). Hys51 represents the first hysteresis parameter of event 5, and Hys52 represents the second hysteresis parameter of event 5. Hys51 and Hys52 may be the same or different.

[0269] In Event 5, more parameters such as Of2, Oc2, Hys51, and Hys52 are referenced, which makes the decision for Event 5 more accurate, flexible, and stable.

[0270] In Event 5, it should be understood that M1 and M2 are determined by the first terminal device. Each of the parameters such as Thresh51, Thresh52, Of2, Oc2, Hys51, and Hys52 may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0271] In Event 5, parameters such as Of2, Oc2, Hys51, and Hys52 are all optional parameters; in other words, only some of the parameters may be used in the expressions of the start condition and / or end condition. This is not limited to the embodiments of this application.

[0272] Event 6: The probability that the second cell functions as the target cell is greater than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting conditions: M2>Mx+Off, and Termination condition: M2 <Mx+Off、ただし、 M2 represents the probability that the second cell functions as the target cell, and the second cell is the cell in the first cell set that has the highest probability of being the target cell. Mx represents the probability that the third cell functions as the target cell, where the third cell is any cell in the first cell set other than the second cell, and Off represents the offset value of event 6.

[0273] In possible embodiments, it can be understood that:

[0274] In Event 6, the second cell can be the first cell.

[0275] In a possible scenario, event 6 can be understood as being used to determine that a cell handover is not temporarily required. In other words, there is a high probability that the first cell will function as the target cell, and the first terminal device does not need to perform a cell handover.

[0276] Another possible embodiment: In Event 6, the second cell is a cell in the first cell set other than the first cell.

[0277] In a possible example, event 6 may be used to initiate a handover. In other words, there is a high probability that at least one cell other than the first cell will function as the target cell. In this case, for example, the first terminal device sends probability-related and / or measurement-related reports to the first network device, which then makes a decision based on the reports and initiates a cell handover. For example, the first network device sends a handover preparation request to the network device corresponding to the target cell, or sends a handover instruction to the first terminal device. In response, the first terminal device may perform the cell handover. See the explanation in Figure 2. Further details are not provided here.

[0278] In some embodiments, event 6 takes the following form: Starting conditions: M2+Of2+Oc2-Hys>Mx+Ofx+Ocx+Off, and Termination condition: M2+Of2+Oc2+Hys <Mx+Ofx+Ocx+Off It may also have, however, M2 represents the probability that the second cell functions as the target cell, and the second cell is the cell in the first cell set that has the highest probability of being the target cell. Mx represents the probability that the third cell functions as the target cell, where the third cell is any cell in the first cell set other than the second cell, and Off represents the offset value of event 6. Of2 represents the first offset of the probability that the second cell functions as the target cell (the first offset may relate to frequency, frequency band, or frequency point), and Oc2 represents the second offset of the probability that the second cell functions as the target cell (the second offset may relate to the second cell). Ofx represents the first offset of the probability that the third cell will function as the target cell (the first offset may relate to frequency, frequency band, or frequency point), Ocx represents the second offset of the probability that the third cell will function as the target cell (the second offset may relate to the third cell), and Hys represents the hysteresis parameter of event 6.

[0279] Event 6 references more parameters such as Of2, Oc2, Ofx, Ocx, and Hys, which makes the decision for Event 6 more accurate, flexible, and stable.

[0280] In Event 6, it should be understood that M2 is determined by the first terminal device. Each of the parameters such as Off, Of2, Oc2, Ofx, Ocx, and Hys may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0281] In Event 6, parameters such as Of2, Oc2, Ofx, Ocx, and Hys are all optional parameters; in other words, only some of the parameters may be used in the expressions of the start condition and / or end condition. This is not limited to the embodiments of this application.

[0282] Event 7: The probability that the second cell functions as the target cell is less than the offset value of the probability that the third cell in the first cell set functions as the target cell. Starting condition: M2 <Mx+Off、および Termination condition: M2 > Mx + Off, however, M2 represents the probability that the second cell functions as the target cell, and the second cell is the cell in the first cell set that has the highest probability of being the target cell. Mx represents the probability that the third cell functions as the target cell, where the third cell is any cell in the first cell set other than the second cell, and Off represents the offset value of event 7.

[0283] In Event 7, it is easy to understand that the second cell may be the first cell, or it may be any cell in the first set of cells other than the first cell.

[0284] In possible embodiments, it can be understood that:

[0285] Event 7 indicates that, in terms of probability, there is no cell with a high probability of being the target cell, making it difficult to decide whether to perform a cell handover or to determine the target cell. Therefore, for example, the first terminal device may interrupt the execution of target cell probability inference to reduce the terminal's power consumption.

[0286] In some embodiments, event 7 takes the following form: Starting condition: M2+Of2+Oc2+Hys <Mx+Ofx+Ocx+Off、および Termination condition: M2+Of2+Oc2-Hys>Mx+Ofx+Ocx+Off It may also have, however, M2 represents the probability that the second cell functions as the target cell, and the second cell is the cell in the first cell set that has the highest probability of being the target cell. Mx represents the probability that the third cell functions as the target cell, where the third cell is any cell in the first cell set other than the second cell, and Off represents the offset value of event 7. Of2 represents the first offset of the probability that the second cell functions as the target cell (the first offset may relate to frequency, frequency band, or frequency point), and Oc2 represents the second offset of the probability that the second cell functions as the target cell (the second offset may relate to the second cell). Ofx represents the first offset of the probability that the third cell will function as the target cell (the first offset may relate to frequency, frequency band, or frequency point), Ocx represents the second offset of the probability that the third cell will function as the target cell (the second offset may relate to the third cell), and Hys represents the hysteresis parameter of event 7.

[0287] Event 7 references more parameters such as Of2, Oc2, Ofx, Ocx, and Hys, which makes the decision for Event 7 more accurate, flexible, and stable.

[0288] In Event 7, it should be understood that M2 and Mx are determined by the first terminal device. Each of the parameters such as Off, Of2, Oc2, Ofx, Ocx, and Hys may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0289] In Event 7, parameters such as Of2, Oc2, Ofx, Ocx, and Hys are all optional parameters; in other words, only some of the parameters may be used in the expressions of the start condition and / or end condition. This is not limited to the embodiments of this application.

[0290] Event 8: The sum of the probabilities of k cells that have a higher probability of being the target cell is greater than the threshold. Starting conditions:

number

number

[0291] In Event 8, it is easy to understand that the aforementioned k cells may or may not include the first cell.

[0292] For example, event 8 is used to initiate another AI / ML model to comprehensively determine the target cell.

[0293] For example, the first terminal device starts AI / ML model 1 and uses AI / ML model 1 to roughly estimate the probability that each of the N cells will function as a target cell, and then uses the first k cells with the higher probability among the N cells to determine event 8.

[0294] When the initiation condition for event 8 is met, AI / ML model 2 is started, and using AI / ML model 2, the probability that each of the aforementioned k cells functions as a target cell is accurately estimated, and then the target cell is determined based on the accurately estimated probabilities. The model may have high operating energy consumption when performing accurate estimation. Therefore, when performing accurate estimation, AI / ML model 2 is started only when event 8 is met, and accurate estimation is performed only for k cells instead of performing accurate estimation for N cells. This helps reduce the operating energy consumption on the terminal device side and can further guarantee the accuracy of the target cell.

[0295] If the conditions for starting Event 8 are not met, AI / ML Model 2 will not start in order to reduce the operating energy consumption of the terminal device.

[0296] In possible embodiments, AI / ML model 1 may be a lightweight AI / ML model and may have low operating energy consumption. AI / ML model 2 may be complex and may have high operating energy consumption.

[0297] In some embodiments, event 8 takes the following form: Starting conditions:

number

number

[0298] At Event 8, M i It should be understood that these parameters are determined by the first terminal device. The k, N, Thresh, and Hys parameters may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0299] Event 9: The sum of the probabilities of k cells that have a higher probability of being the target cell is less than the threshold. Starting conditions:

number

number

[0300] In Event 9, it is easy to understand that the aforementioned k cells may or may not include a first cell (i.e., which can be described as a source cell or a serving cell).

[0301] For example, event 9 is used to temporarily stop the inference of the AI / ML model.

[0302] For example, the first terminal device starts the AI / ML model 1, roughly estimates the probability that each of the N cells functions as a target cell using the AI / ML model 1, and then uses the first k cells with higher probabilities among the N cells to determine event 9.

[0303] When the start condition of event 9 is satisfied, the inference using the AI / ML model 1 is temporarily stopped to help reduce the operating energy consumption on the terminal device side.

[0304] In some embodiments, event 9 has the following format: Start condition:

Number

Number

[0305] In event 9, M iIt should be understood that these parameters are determined by the first terminal device. The k, N, Thresh, and Hys parameters may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0306] Event 10: The probability of cell handover is greater than the threshold. Starting conditions: P > Thresh, and Termination condition: P <Thresh、ただし、 P represents the probability that a cell handover should be performed, and Thresh represents the threshold corresponding to event 10.

[0307] For example, in one instance, event 10 is used to initiate a handover. In other words, there is a high need to perform a cell handover, and the first terminal device may perform the cell handover.

[0308] In another example, event 10 may be used further to initiate another event or AI / ML model to precisely determine the target cell. The AI / ML model for event 10 may be simple, while the AI / ML model for precisely determining the target cell may be complex and have high power consumption. The AI / ML model for precisely determining the target cell is initiated only when event 10 is met, thereby reducing the terminal's power consumption.

[0309] In addition, the inequality for event 10 is, or the starting condition:

number

number

number

[0310] It can be understood that the probability of not needing to perform a cell handover is smaller than a certain threshold.

[0311] In some embodiments, event 10 takes the following form: Starting conditions: P-Hys>Thresh, and Termination condition: P+Hys <Thresh It may also have, however, P represents the probability that a cell handover should be performed, Thresh represents the threshold corresponding to event 10, and Hys represents the hysteresis parameter for event 10, which makes the decision on event 10 more accurate, flexible, and stable.

[0312] In event 10, it should be understood that P is determined by the first terminal device. The Thresh and Hys parameters may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0313] Event 11: The probability of cell handover is less than the threshold. Starting condition: P <Thresh、および Termination condition: P > Thresh, however, P represents the probability that a cell handover should be performed, and Thresh represents the threshold corresponding to event 11.

[0314] For example, in one instance, event 11 is used to temporarily halt the inference of an AI / ML model.

[0315] For example, the first terminal device starts AI / ML model 1, uses AI / ML model 1 to estimate the probability P of a cell handover, and then uses the probability P of a cell handover to determine event 11.

[0316] If the conditions for triggering Event 11 are met, inference using AI / ML Model 1 will be temporarily suspended to help reduce the operating energy consumption of the terminal device.

[0317] In addition, the inequality for event 11 is, or the starting condition:

number

number

number

[0318] It can be understood that the probability of not needing to perform a cell handover is greater than a certain threshold.

[0319] In some embodiments, event 11 takes the following form: Starting condition: P+Hys <Thresh、および Termination condition: P-Hys>Thresh It may also have, however, P represents the probability that a cell handover should be performed, Thresh represents the threshold corresponding to event 11, and Hys represents the hysteresis parameter for event 11, which makes the decision on event 11 more accurate, flexible, and stable.

[0320] In Event 11, it should be understood that P is determined by the first terminal device. The Thresh and Hys parameters may be configured by the network side, agreed upon by the two communicators, or determined by the first terminal device. This is not limited to the embodiments of this application.

[0321] The following supplementary explanations are provided regarding events 1 through 11 mentioned above.

[0322] Firstly, M1, M2, Mx, M i , and

[0323] M1, M2, Mx, M i , and

number

[0324] Secondly, the parameters determined by the first terminal device are as follows: M1, M2, Mx, M i , and

number

[0325] For example, the first terminal device uses AI / ML model inference to determine the aforementioned parameters (i.e., M1, M2, Mx, M i , and

number

[0326] In possible embodiments, the AI / ML model may be generated by a first terminal device, or the AI / ML model may be delivered or transferred to the first terminal device by a network device (e.g., a first network device). This is not limited to the embodiments of this application.

[0327] For example, in the embodiments of this application, the AI / ML model may be a model constructed using machine learning techniques or artificial intelligence techniques, such as a convolutional neural network, a long short-term memory (LSTM) network, a transformer network, linear regression, logistic regression, a decision tree, a support vector machine (SVM), a Bayesian network, a Q-learning model, or a model constructed based on another technique.

[0328] In embodiments of this application, the output of the AI / ML model may relate to the probability that a cell in a first cell set functions as a target cell. For example, in a possible embodiment, the AI / ML model outputs the probability that each cell in the first cell set functions as a target cell, and M1, M2, Mx, and M iIt may include one or more of the following. The output of the AI / ML model may also relate to whether a handover is requested. For example, the AI / ML model may include the probability P that a handover is requested and / or the probability that a handover is not requested.

number

[0329] In embodiments of this application, a softmax function or another technique may be used in the last layer of the AI / ML model to output a probability (for example, the probability that the first cell will function as the target cell).

[0330] In embodiments of this application, the output of the AI / ML model may be a probability, or not a probability, but may represent a value of relative probability (e.g., the relative probability that a first cell functions as a target cell), or may be represented through processing. This is not limited to embodiments of this application. This application does not preclude the possibility that different names or expressions may be defined in future protocols to represent the same or similar meanings. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of embodiments of this application that satisfy the characteristics of Configuration 1 in embodiments of this application shall be within the scope of protection of embodiments of this application.

[0331] In the embodiments of this application, the input to the AI / ML model is: Item 1: Measured quantities acquired by the first terminal device through measurement, for example, the SINR value acquired by the first terminal device by measuring SINR, the RSRP value acquired by measuring RSRP, the RSRQ value acquired by measuring RSRQ, the RSSI value acquired by measuring received signal strength indication (RSSI), and the RSCP value acquired by measuring received signal code power (RSCP). Item 2: Channel state information (CSI), Third item: At least one of the location information and tracking information of the first terminal device (multiple consecutive location information may constitute the tracking information of the first terminal device), Item 4: Motion information of the first terminal device, for example, the operating speed and acceleration of the first terminal device. Item 5: Service information of the first terminal device, for example, one or more of the service type, service load, and service duration of the first terminal device, and Item 6: Time information, which may include the time corresponding to the measured quantity or other information obtained by the first terminal device through the measurement. This may include, but is not limited to, the following. For example, the time information includes time point 1 and time point 2. The measurement corresponding to time point 1 is represented as measurement 1. The measurement corresponding to time point 2 is represented as measurement 2. In addition, the time information may be absolute time (e.g., UTC time) or relative time (e.g., system frame number (SFN)). This is not limited to the embodiments of this application.

[0332] It is easy to understand that the input information for an AI / ML model may include information at a specific point in time, information corresponding to multiple consecutive points in time, information corresponding to multiple frequencies (which may be replaced by frequency points or frequency bands), or information corresponding to multiple cells. The input information for an AI / ML model may be the aforementioned raw information, or information obtained by processing the raw information. This is not limited to the embodiments of this application.

[0333] Thirdly, the aforementioned parameters (for example, M1, M2, Mx, M i , and

number

[0334] Example 1: AI / ML model 1 is used to infer M1, and AI / ML model 2 is used to infer M2.

[0335] Example 2: AI / ML model 1 is used to infer M1 and M2.

[0336] Examples 1 and 2 described above are used to illustrate the correspondence between AI / ML models and parameters, and should not be interpreted as limitations on the embodiments of this application.

[0337] In addition, the first terminal device uses a different method instead of using the AI / ML model inference method to calculate the aforementioned parameters (e.g., M1, M2, Mx, M i , and

number

[0338] Fourth, the events of Configuration 1 and the mobility-specific configuration events in the current 5G communication system (e.g., events A1, A2, A3, A4, A5, A6, B1, or B2 in S201) may be configured and executed individually or together. When configured together, the events may be configured sequentially or in parallel. For example, two events are used as an example. With respect to events X and Y, either event X or event Y may be configured alone, or events X and Y may be configured together. When events X and Y are configured together, events X and Y may be executed / triggered simultaneously, or event Y may be executed after event X has been triggered.

[0339] In some embodiments, when configuration information is used to configure configuration 1, the configuration information is as follows: Item 1: Trigger duration, which is expressed as TTT, for example, and the trigger duration indicates the period of time during which the event start condition is continuously met, and Second item: A trigger count, for example, represented as NTT, where the trigger count indicates the number of times the event start condition is met consecutively. It is further used to constitute at least one of the following.

[0340] The event start conditions include the event start conditions of Configuration 1.

[0341] For example, when the configuration information includes TTT, for instance, TTT is 5 slots.

[0342] For the first terminal device, event 1 serves as an example. After the first terminal device initially determines that the trigger condition for event 1 is met, the trigger condition for event 1 is subsequently met for five consecutive slots. In this case, the first terminal device decides to trigger event 1, which helps improve event determination accuracy.

[0343] For example, when the configuration information includes NTT, NTT appears 5 times.

[0344] For the first terminal device, event 1 serves as an example. After initially determining that the trigger condition for event 1 is met, the first terminal device determines that the trigger condition for event 1 is still met five times in a row. In this case, the first terminal device decides to initiate event 1, which helps improve event determination accuracy.

[0345] In some embodiments, when configuration information is used to configure configuration 1, the configuration information includes an event sequence number or an event identifier. The event sequence number indicates an event configured using the configuration information, and the event identifier identifies an event configured using the configuration information.

[0346] For example, an event identifier serves as an example, with events 1 through 11 being identified by letters, such as A through K. When configuration information is used for event 1 of configuration 1, the configuration information includes the event identifier for event 1, such as the letter A.

[0347] In another example, event sequence numbers are used as an example, with events 1 through 11 being identified using sequence numbers, e.g., 1 through 11. When configuration information is used for event 1 of configuration 1, the configuration information includes the sequence number of event 1, e.g., the number 1.

[0348] In other words, configuration information is used to configure events using event sequence numbers and / or event identifiers to help reduce signaling overhead.

[0349] In some embodiments, when configuration information is used to configure configuration 1, the first terminal device further performs the following operations, as shown in Figure 4.

[0350] (Optional) S304: The first terminal device starts inference based on configuration 1.

[0351] For example, the first terminal device determines, based on the inference results, whether a handover needs to be performed or information such as the probability that the second cell will become the target cell, in order to obtain a more accurate handover opportunity and / or a more accurate target cell.

[0352] (Optional) S305: The first terminal device stops inference based on configuration 1.

[0353] For example, when the conditions for starting event 1 are met, the first terminal device may assume that a handover is not temporarily requested and may temporarily suspend inferences regarding whether a handover is requested or the probability that the second cell will become the target cell.

[0354] In this way, the first terminal device reduces power consumption on the terminal side by stopping inference in a timely manner based on configuration 1.

[0355] In some embodiments, as shown in Figure 4, the first terminal device further performs the following operations.

[0356] (Optional) S306: The first terminal device sends the second information to the first network device. In response, the first network device receives the second information from the first terminal device.

[0357] The second piece of information is as follows: Item 1: An identifier for at least one cell, the cell identifier may be a physical cell identifier (PCI), and at least one cell is one or more cells that satisfy configuration 1, and Second item: An event identifier that triggers the second piece of information, wherein the event identifier is one or more of the events in configuration 1. It includes at least one of the following.

[0358] In one example, the first terminal device first determines that the trigger condition for event 6 has been met, and then determines the cell indicated by the second information, which includes the second cell of event 6. In this case, the second information includes the identifier of the second cell and the event identifier of event 6.

[0359] Alternatively, the first terminal device determines that the trigger conditions for event 8 have been met. The second information may include an event identifier that triggers the second information, i.e., the event identifier of event 8. Optionally, the second information may further include cell identifiers, for example, the identifiers of k cells in event 8, or the cell identifier of a target cell selected from the k cells. This is not limited to the embodiments of this application.

[0360] In another example, the first terminal device determines the cell indicated by the second information based on the events of configuration 1 (e.g., events 1 through 11 mentioned above) and mobility-specific configuration events in the current 5G communication system (e.g., events A1, A2, A3, A4, A5, A6, B1, or B2 in S201).

[0361] For example, the second piece of information further includes probabilistic information, which includes the probability that the cell indicated by the second piece of information functions as a target cell.

[0362] For example, when the second piece of information indicates cell 1, it includes the PCI and probability value for cell 1. The probability value indicates the probability that cell 1 will function as a target cell.

[0363] It should be understood that the second piece of information may further include other measurement information, such as the measurement quantities of the first terminal device. Specifically, the first terminal device initiates an inter-frequency / inter-radio access technology measurement to obtain the measurement quantities of the inter-frequency / inter-radio access technology measurement and uses the second piece of information to report the measurement quantities to the first network device.

[0364] It can be understood that the second piece of information may be sent to the first network device by the first terminal device via a single message, or it may be sent to the first network device by the first terminal device via multiple messages.

[0365] (Optional) S307: The first network device determines the target cell based on the second information.

[0366] For example, based on the second information, the first network device decides whether to perform a cell handover, the target cell after the cell handover, and at least one of the following: a cell handover policy. The cell handover may be one of the following: an intra-frequency handover, an inter-frequency handover, an inter-radio access technology handover, a conditional handover, or a dual-active protocol stack handover. The cell handover policy includes a handover or redirection.

[0367] (Optional) S308: The first network device notifies the second network device to perform handover preparations.

[0368] The second network device is the network device corresponding to the target cell. For details, please refer to the explanation in S205.

[0369] (Optional) S309: The first terminal device, the first network device, and the second network device perform a handover.

[0370] For example, the first terminal device disconnects from the first network device and initiates a RACH procedure to the second network device. See the explanation in S206 for details.

[0371] Next, configuration 2 will be explained in detail.

[0372] In configuration 2, configuration information is presented to the first terminal device so as to determine the first information based on the first submodel.

[0373] In possible embodiments, for example, a first terminal device and a network device (e.g., a first network device) may implement Configuration 2 based on AI / ML model identity (ID) and / or functionality. When Configuration 2 is implemented based on AI / ML model ID, the configuration information includes AI / ML model ID directive information, which indicates a specific AI / ML submodel to be used for inference, or an AI / ML submodel to be initiated. When Configuration 2 is implemented based on functionality, the configuration information includes functionality directive information, which indicates the operation of an AI / ML mode, or an AI / ML mode to enable a function, such as a mobility-related function, in order to configure the first terminal device to determine first information based on the first submodel by binding the first submodel and the function.

[0374] In another example, a first terminal device and a first network device agree in advance that the first terminal device will determine first information based on a first submodel. In this case, when the first network device configures the first terminal device to report first information using configuration information, the first terminal device will determine first information based on the first submodel.

[0375] In some embodiments, a model alignment step is further included before S301, as shown in Figure 5. Alternatively, the aforementioned model alignment step is further included after S301, before the first terminal device performs S314.

[0376] During the model alignment phase, the first terminal device and the first network device perform model alignment. Model alignment means that the first submodel of the first terminal device and the second submodel of the first network device can be interconnected. For example, an AI / ML model includes two parts, namely a first submodel and a second submodel. The first terminal device uses the first submodel to perform inference and obtains a first inference result (i.e., first information). The first network device inputs the first inference result into the second submodel and uses the second submodel to perform inference and obtain a second inference result.

[0377] In possible embodiments, the network side trains and configures a dual-end model. The dual-end model includes a terminal-side model and a network-side model. The terminal-side model is a submodel configured for a first terminal device, i.e., the first submodel. The network-side model is a submodel configured for a first network device, i.e., the second submodel.

[0378] Of course, there can be multiple ways of configuring the submodel. This is not limited to the embodiments of this application.

[0379] In some embodiments, the first terminal device executes S314 after deciding to determine first information based on a first submodel.

[0380] S314: The first terminal device generates first information based on the first submodel.

[0381] For example, the first piece of information is the following: Item 1: Measured quantity acquired by the first terminal device through measurement, Item 2: Channel status information, Third item: At least one of the location information and tracking information of the first terminal device, Item 4: Movement information of the first terminal device, Item 5: Service information for the first terminal device, and Item 6: Time Information It relates to one or more of the following.

[0382] For details regarding the first through sixth information items, please refer to the explanation in Configuration 1. Further details will not be provided here.

[0383] The first through sixth information items may also be input information for the first submodel, and are used by the first submodel to perform inference in order to output the first information.

[0384] The first to sixth information items may include information at a specific point in time, information corresponding to multiple consecutive points in time, information corresponding to multiple frequencies (which may be replaced by frequency points or frequency bands), or information corresponding to multiple cells. The input information for the first submodel may be the aforementioned source information, or information obtained by processing the source information. This is not limited to the embodiments of this application.

[0385] For example, the first information may be information obtained by performing a process that uses the first submodel. The process performed using the first submodel may include, but is not limited to, refinement or compression to reduce the transmission load, further reducing the possibility of exposing the internal information of the first terminal device.

[0386] S315: The first terminal device sends the first information to the first network device. In response, the first network device receives the first information from the first terminal device.

[0387] It can be understood that the first information may be sent to the first network device by the first terminal device via a single message, or it may be sent to the first network device by the first terminal device via multiple messages.

[0388] S316: The first network device determines the target cell based on the first information and the second submodel.

[0389] For example, a first network device inputs first information into a second submodel, uses the second submodel to perform inference and obtain a second inference result, and then determines a target cell based on the second inference result.

[0390] For example, the second inference result may be a probability, such as a probability related to configuration 1. In this case, the first network device determines the target cell based on the second inference result and the events of configuration 1.

[0391] Alternatively, the second inference result may be other information. In response, the first network device determines the target cell based on the second inference result using a different processing method. This is not limited to the embodiments of this application.

[0392] In another example, the first network device inputs the first information and reference information into the second submodel, uses the second submodel to perform inference and obtain the second inference result, and then determines the target cell based on the second inference result.

[0393] The reference information includes information about at least one network device, e.g., information about a first network device and / or information about a second network device corresponding to a cell. The reference information is cell-related and includes, for example, the load status of each cell.

[0394] For example, the second inference result includes the probability value P1 that cell 1 functions as the target cell, the probability value P2 that cell 2 functions as the target cell, and the probability value P3 that cell 3 functions as the target cell.

[0395] The reference information includes the load status of cell 1, the load status of cell 2, and the load status of cell 3.

[0396] In this case, in possible scenarios, even if cell 3 has the highest probability P3 of functioning as a target cell, if cell 3 is currently under the highest load, the first network device will similarly select one cell from cell 1 and cell 2 as a target cell to avoid the impact on the cell handover success rate of the first terminal device due to the excessive load on cell 3.

[0397] (Optional) S317: The first network device notifies the second network device to perform handover preparations.

[0398] The second network device is the network device corresponding to the target cell. For details, please refer to the explanation in S205.

[0399] (Optional) S318: The first terminal device, the first network device, and the second network device perform a handover.

[0400] For example, the first terminal device disconnects from the first network device and initiates a RACH procedure to the second network device. See the explanation in S206 for details.

[0401] Next, the events of configuration 3 will be explained in detail.

[0402] In the event of configuration 3, the first point in time is a future point in time, and the first time period is a future time period.

[0403] In the event of configuration 3, the predicted result of the measured object can also be called the measured quantity without causing confusion.

[0404] In the event of configuration 3, the measurement at the first time point is obtained by the first terminal device through prediction. For example, the first terminal device predicts the measurement at the first time point based on the measurement during the second time period. In this case, the first time point is later than any point in the second time period.

[0405] Similarly, the quantified quantity for the first time period is obtained by the first terminal device through prediction. For example, the first terminal device predicts the quantified quantity for the first time period based on the quantified quantity for the second time period. In this case, the first time period is later than the second time period.

[0406] The measurement quantity for the second time period is acquired by the first terminal device through measurement.

[0407] In configuration 3, the measured quantity at the first time point (first time period) may be the original value of the measured quantity at the first time point (first time period), or it may include a value obtained by processing the measured quantity at the first time point (first time period), such as the mean, maximum, or minimum value of the measured quantity at the first time point (first time period), and may further include measured quantities corresponding to multiple frequencies (which may be replaced by frequency points or frequency bands), and may further include measured quantities corresponding to multiple cells.

[0408] For example, when predicting a quantifier at a first time point (or first time period), in addition to using a quantifier from a second time period, the first terminal device may further use one or more of the following information: channel status information, location information and tracking information of the first terminal device, motion information of the first terminal device, and time information. See the description in S314 for details. Details are not described again here. The information used to predict the quantifier at a first time point (or first time period) may belong to the second time period or extend beyond the second time period (including at least the second time period). This is not limited to the embodiments of this application.

[0409] The events in configuration 3 may include at least one of the following:

[0424] It should be understood that the events in Configuration 3 (for example, events 12 through 19 mentioned above) can maximize the use of existing standard protocol frameworks.

[0425] In configuration 3, it should be understood that the quantifier at the first time point (first time period) may be Ms, Mp, or Mn, etc., in events 12 through 19. The quantifier at the first time point (first time period) may be obtained by the first terminal device through inference based on an AI / ML model, or may be determined by another method. This is not limited to the embodiments of this application.

[0426] It should be understood that the measurement target corresponding to the measurement quantity related to configuration 3, for example, the measurement target corresponding to the measurement quantity at the first time point (or first time period), or the measurement target corresponding to the measurement quantity at the second time period, may be one or more of RSRP, RSRQ, or SINR.

[0427] In some embodiments, when configuration information is used to configure configuration 3, the configuration information is as follows: Item 1: Trigger duration, which is expressed as TTT, for example, and the trigger duration indicates the period of time during which the event start condition is continuously met, and Second item: A trigger count, for example, represented as NTT, where the trigger count indicates the number of times the event start condition is met consecutively. It is further used to constitute at least one of the following.

[0428] The event start conditions include the event start conditions for configuration 3.

[0429] For example, TTT and NTT help improve event determination accuracy. See the description of Configuration 1 for details. Further details will not be explained here.

[0430] In some embodiments, when configuration information is used to configure configuration 3, the configuration information includes an event sequence number or an event identifier. The event sequence number indicates an event configured using the configuration information, and the event identifier identifies an event configured using the configuration information.

[0431] In other words, configuration information is used to configure events using event sequence numbers and / or event identifiers to help reduce signaling overhead. See the description of Configuration 1. Further details are not provided here.

[0432] In some embodiments, configuration information is further used to configure a second time period. The quantifier of the second time period is used to predict the quantifier of configuration 3 (for example, when configuration 3 is used to configure an event related to the quantifier of the first time point, the quantifier of configuration 3 includes the quantifier of the first time point; in another example, when configuration 3 is used to configure an event related to the quantifier of the first time period, the quantifier of configuration 3 includes the quantifier of the first time period), and the quantifier of the second time period is obtained by a first terminal device through measurement.

[0433] For example, the method for constructing the second time period is explained as follows:

[0434] Method 1: The configuration information further indicates the start and end times of the second time period.

[0435] Method 2: The configuration information further indicates the start time and duration of the second time period.

[0436] Method 3: The configuration information further indicates the start time of the second time period, the number of measurements of the measured quantity during the second time period, and the measurement gap of the measured quantity during the second time period.

[0437] Method 4: The configuration information further indicates the end time of the second time period, the number of measurements of the measured quantity during the second time period, and the measurement gap of the measured quantity during the second time period.

[0438] It should be understood that Methods 1 through 4 are merely examples illustrating methods for constructing a second time period. Of course, other types of construction methods may exist, and this is not limited to the embodiments of this application.

[0439] In other words, the first network device may further configure a second time period, thereby allowing the first terminal device to determine the measurement of the first time point (or first time period) based on the measurement of the second time period.

[0440] In some embodiments, when configuration information is used to configure configuration 3, the first terminal device further performs the following operations, as shown in Figure 6.

[0441] (Optional) S326: The first terminal device sends the third information to the first network device. In response, the first network device receives the third information from the first terminal device.

[0442] The third piece of information is as follows: Item 1: An identifier for at least one cell, the identifier for at least one cell, the identifier for at least one cell being one or more of the cells satisfying configuration 3, and Item 2: Measurement identifier that triggers the third piece of information. It includes at least one of the following: The measurement identifiers are as follows: Item 1: At least one measurement target, wherein each measurement result of the at least one measurement target is one measurement quantity of configuration 3, for example, the measurement identifier includes a measurement target identifier, the measurement target identifier identifies the measurement target, and in the embodiments of this application, the measurement target may include RSRP, RSRQ, and SINR, and the measurement target identifier may include an identifier for RSRP, an identifier for RSRQ, and an identifier for SINR, at least one measurement target, and Second item: at least one event, each of which is an event configured using configuration 3. Identify one or more of them.

[0443] In some embodiments, the third information further includes a fourth piece of information, which includes a measurement of a cell at a first time point (or first time period) as indicated by the third piece of information.

[0444] For example, when the third piece of information points to cell 1, the third piece of information further includes the RSRP value. The RSRP value represents the measured quantity in cell 1 at a first time point (or first time period).

[0445] It should be understood that the third piece of information may further include other measurement information, such as measured quantities obtained by the first terminal device through the measurement.

[0446] It should be further understood that the third piece of information may be sent to the first network device by the first terminal device via a single message, or it may be sent to the first network device by the first terminal device via multiple messages.

[0447] (Optional) S327: The first network device determines the target cell based on the third piece of information.

[0448] For example, based on the third piece of information, the first network device decides whether to perform a cell handover, the target cell after the handover, and at least one of the following: the cell handover policy. See the description in S307 for details. Details are not explained here again.

[0449] (Optional) S328: The first network device notifies the second network device to perform handover preparations.

[0450] The second network device is the network device corresponding to the target cell. For details, please refer to the explanation in S205.

[0451] (Optional) S329: The first terminal device, the first network device, and the second network device perform a handover.

[0452] For example, the first terminal device disconnects from the first network device and initiates a RACH procedure to the second network device. See the explanation in S206 for details.

[0453] It should be noted that in all embodiments of this application, all greater than signs (>) may be replaced with greater than signs (≧), and all less than signs (<) may be replaced with less than signs (≦). This is not limited to this application.

[0454] In all embodiments of this application, when configuration information is used to configure the aforementioned events and / or event parameters (such as Of1, Oc1, Of2, Oc2, Ofx, Ocx, Hys, Thresh, k, N, TTT, or NTT), the same message may be used for configuration, or different messages may be used for configuration. This is not limited to the embodiments of this application.
