In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0128] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0133] In communication systems, such as 5G systems, the network configures the UE to perform measurements. The measurement configuration includes the following parameters:

[0134] 1. Measurement object: A list of objects that the UE measures. For intra-frequency and inter-frequency measurements, the measurement object indicates the time-domain, frequency-domain location, and subcarrier spacing of the reference signal.

[0135] 2. The reporting configuration includes reporting criteria, reference signal types, and reporting formats. Reporting criteria refer to the rules that trigger the UE to send measurement reports; these can be periodic or event-driven.

[0136] 3. Measurement identity links the measurement object to the reporting configuration.

[0137] 4. The quantity configuration defines the measurement filtering configuration.

[0138] 5. Measurement gap refers to a period of time reserved by the UE for measurement, during which the UE will not send or receive data.

[0139] In event-driven reporting, when the UE discovers that the conditions configured by the network (i.e., event) are met, the UE reports the measurement results. Taking Event A3 as an example. Event A3 means that after considering various offsets, the neighboring cell is better than the SpCell (sPCell = PCell + PSCell, where PCell is the primary cell and PSCell is the primary and secondary cell). The entering condition of Event A3 is: Mn + Ofn + Ocn – Hys > Mp + Ofp + Ocp + Off, and the leaving condition is: Mn + Ofn + Ocn + Hys < Mp + Ofp + Ocp + Off. Here, Mn is the measurement result of the neighboring cell, and Mp is the measurement result of the SpCell. Ofn and Ocn are the offsets of the neighboring cell, Ofp and Ocp are the offsets of the SpCell, Off is the offset configured for A3 event, and Hys is the hysteresis of A3 event. When the duration for which the UE discovers that the measurement results meet the entering condition reaches the configured timeToTrigger (trigger time), the UE adds the information of the corresponding neighboring cell to the cellsTriggeredList corresponding to the measID corresponding to A3 event in the UE variable VarMeasReportList (report list). Then the UE reports the corresponding measurement results. When the duration for which the UE discovers that the measurement results meet the leaving condition reaches the configured timeToTrigger (trigger time), the UE deletes the information of the corresponding neighboring cell from the cellsTriggeredList corresponding to the measID corresponding to A3 event in the UE variable VarMeasReportList. If reportOnLeave in the corresponding reporting configuration is set to true, then the UE reports the corresponding measurement results.

[0140] The UE reports the measurement results using the RRC (Radio Resource Control) message MeasurementReport. When the UE reports the measurement results (in IEMeasResults), the UE reports the measurement identifier (measID) that triggered the reporting, the measurement results of the serving cell, and the measurement results of the neighboring cells. The measurement results of the neighboring cells will include the cells in the cellTriggeredList (up to maxReportCells). For each reported neighboring cell, its physical cell identifier (physCellId) and the cell measurement results are reported.

[0141] Machine learning algorithms are one of the most important methods for implementing artificial intelligence technology. Machine learning can obtain models from large amounts of training data, and these models can then predict events. In many fields, models trained using machine learning can achieve highly accurate predictions. In 5G or future 6G systems, or subsequent communication systems, AI can be used for prediction and inference to improve system performance. Terminals can use AI to predict measurement events based on network configuration. When reporting measurement results, terminals also report information about the measurement events predicted by AI, such as the time when the predicted measurement events meet configuration conditions.

[0142] In related technologies, the AI-based switching process is shown in Figure 1B, and includes the following steps:

[0143] 1. The terminal reports information about measurement events predicted by AI, such as the time when the AI-predicted measurement events meet the configuration conditions.

[0144] 2. The source access network device initiates the handover and sends a handover request message (HANDOVER REQUEST) through the Xn interface.

[0145] 3. The target access network device performs access control.

[0146] 4. The target access network device provides the new RRC configuration in the HANDOVER REQUEST ACKNOWLEDGE message.

[0147] 5. The source access network device forwards the RRC reconfiguration message (also known as the handover command HO_CMD) from the HANDOVER REQUEST ACKNOWLEDGE message to the terminal, thereby providing RRC configuration. The timing of the source access network device sending the handover command is determined by the network implementation. For example, the source access network device sends the handover command when the measurement event meets the configuration conditions (rather than when the measurement event predicted by AI meets the configuration conditions).

[0148] 6. Switch the terminal to the new cell.

[0149] 7. The terminal responds to the first network device with RRC Reconfiguration Complete.

[0150] In the AI-based handover process, during the handover preparation phase, the target access network device performs access control and reserves radio resources and processing capabilities for the terminal. If the measured event does not meet the configured conditions, the target access network device may continuously reserve radio resources and processing capabilities for the terminal, which will affect other terminals' access to or handover to the target access network device.

[0151] Therefore, to address the aforementioned issues, this disclosure provides a method for a target access network device to handle reserved resources during an AI-based handover process. The target access network device can cancel the AI-based handover or notify the source access network device of the duration for which the target access network device reserves radio resources and processing capabilities for the terminal. Through this method, the target access network device only reserves necessary resources for AI-based handover, thus avoiding the need to continuously reserve resources for the terminal. This allows resources to be provided to other terminals, enabling full utilization of resources and providing services to more terminals.

[0152] Therefore, this disclosure proposes a communication method, communication device, communication system, storage medium, and program product, which sends first information and / or second information to a first network device through a second network device to cancel time information related to the resource reservation for the terminal device based on model prediction of cell handover or to notify the first network device, so as to avoid resource waste caused by long-term resource reservation and realize full utilization of resources.

[0153] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiments of the present disclosure relate to a communication method, which includes:

[0154] Step S2101: The terminal device sends third information to the first network device.

[0155] In some embodiments, the third information at least indicates information related to cell handover.

[0156] In some embodiments, the relevant information is the result predicted by the terminal device using an artificial intelligence (AI) model or AI function. This relevant information is used for cell handover based on model prediction, or for cell handover based on function prediction, or for cell handover based on AI prediction. The relevant information may also be parameters used to trigger cell handover, or parameters used to determine whether cell handover can be performed.

[0157] In some embodiments, cell handover may be triggered by predictions or results obtained from AI models or AI functions; alternatively, cell handover may be a first type of cell handover triggered by predictions or results obtained from AI models or AI functions; or, cell handover may be triggered by actual parameters. This disclosure does not limit the scope of the handover. In some embodiments, the terminal device may use models for prediction, such as AI-based predictions or machine learning-based predictions.

[0158] In some embodiments, the relevant information includes at least one of the following: the time when the measurement event meets the configuration conditions; the parameters of the measurement event; the measurement event; and whether the measurement event meets the configuration conditions.

[0159] In some embodiments, the relevant information (i.e., the result obtained by the terminal device using the model to make predictions) includes at least one of the following: the time when the measurement event predicted by the model meets the configuration conditions; the parameters of the measurement event predicted by the model; the measurement event predicted by the model; whether the measurement event predicted by the model meets the configuration conditions; and the probability value of the result predicted by the model, the probability value including accuracy or confidence.

[0160] In some embodiments, the result obtained by the terminal device using the model for prediction can be a directly predicted result or an indirectly predicted result. Direct prediction means that the model's input is a series of historical measurement results, and the result at the current moment is predicted based on these historical results. Indirect prediction means that the model predicts relevant parameters of the measurement event, and uses these parameters to further obtain the result.

[0161] The following explanation uses indirect prediction as an example:

[0162] In some embodiments, the result obtained by the terminal device using the model for prediction may be the parameters of the measured event, such as parameters Mn and Mp in Event A3.

[0163] In some embodiments, model-based prediction can be a prediction of the measured event. For example, the terminal device uses AI to predict whether Event A3 is satisfied. That is, based on the predicted parameters Mn and Mp, it predicts whether the measured event is satisfied. Specifically, it predicts the relationship between the values ​​of Mn+Ofn+Ocn–Hys and Mp+Ofp+Ocp+Off. When it is determined that Mn+Ofn+Ocn–Hys > Mp+Ofp+Ocp+Off, the measured event satisfies the entry condition. When Mn+Ofn+Ocn–Hys < Mp+Ofp+Ocp+Off, the measured event satisfies the exit condition.

[0164] In some embodiments, model-based prediction can be a prediction of whether a measured event meets the configuration conditions. For example, the terminal device uses AI to predict whether the duration after Event A3 is met meets the configuration conditions, i.e., whether the configured duration is reached.

[0165] For example, when the UE detects that the duration for which the measurement result meets the entering condition has reached the configured timeToTrigger, the UE adds the corresponding neighbor cell information to the cellsTriggeredList corresponding to the measID of the A3 event in the UE variable VarMeasReportList. Then, the UE reports the corresponding measurement result at the time the configured timeToTrigger is reached. When the UE detects that the duration for which the measurement result meets the leaving condition has reached the configured timeToTrigger, the UE removes the corresponding neighbor cell information from the cellsTriggeredList corresponding to the measID of the A3 event in the UE variable VarMeasReportList. If the corresponding reporting configuration's reportOnLeave is set to true, then the UE reports the corresponding measurement result.

[0166] In some embodiments, model-based prediction can be the prediction of the time when a measured event meets the configuration conditions. For example, the terminal device uses AI to predict the time when the duration after Event A3 is met will reach the configuration conditions.

[0167] For example, after the UE detects that the measurement result satisfies the entering condition for a duration that reaches the configured timeToTrigger, it will use the corresponding time as the result.

[0168] In some embodiments, the probability value includes any one of the following: the accuracy of the relevant information; the confidence level of the relevant information. The probability value is used to characterize the accuracy of the result predicted by the terminal device through an AI model or AI function, or to reflect the credibility of the predicted result; the probability value can be a value less than 1.

[0169] In some embodiments, the terminal device can determine the probability value of relevant information by comparing the relevant information predicted using an AI model or AI function with the relevant information in the historical handover process to obtain accuracy or confidence. For example, if the relevant information in the historical process caused the cell handover to fail, the probability value is close to 0 when the relevant information obtained this time is similar to the relevant information in the past. If the relevant information in the historical process caused the cell handover to succeed, the probability value is close to 1 when the relevant information obtained this time is similar to the relevant information in the past. If the relevant information in the historical process caused the cell handover to succeed, the probability value can be determined based on the similarity between the relevant information obtained this time and the relevant information in the past. The degree of similarity can be obtained based on any correlation determination / calculation / prediction method, which is not limited in this embodiment.

[0170] In some embodiments, the probability value of the result predicted by the model can be the probability of the prediction based on AI switching, such as the accuracy of the corresponding AI prediction, the confidence level of the corresponding AI prediction, etc., and the value range can be between 0 and 1, or a percentage, that is, an integer between 1 and 100, for example, 1 indicates 1%, 2 indicates 2%, and so on.

[0171] In some embodiments, the probability value mentioned above includes any one of the following: the accuracy of the relevant information predicted using the model; and the confidence level of the relevant information predicted using the model.

[0172] In some embodiments, the relevant information includes the time when the measured event predicted by the model satisfies the configuration conditions, and the probability value is used to represent the accuracy or confidence level of the corresponding model prediction. For example, at time T1, the measured event has lasted for a preset duration (satisfying the configuration conditions), such as the enter condition being satisfied and lasting for a preset duration. The probability value can be the accuracy or confidence level of the time when the measured event predicted by the model satisfies the configuration conditions.

[0173] In some embodiments, the relevant information includes parameters of the measurement time predicted by the model, such as predicted parameters Mn, Mp, etc., and probability values ​​are used to represent the accuracy or confidence of the corresponding parameters. These parameters are provided to the first network device, which determines whether the conditions are met.

[0174] In some embodiments, the result of model prediction can be a measurement event predicted by the model, i.e., entering condition: Mn+Ofn+Ocn–Hys>Mp+Ofp+Ocp+Off, and the probability value can be the accuracy or confidence level of the measurement event predicted by the model.

[0175] In some embodiments, the result of model prediction can be whether the measured event meets the configuration conditions, such as "yes or no", i.e., whether the entering condition has lasted for a preset duration. The probability value can be the accuracy or confidence of whether the measured event predicted by the model meets the configuration conditions.

[0176] In some embodiments, the terminal device may send the updated third information to the first network device so that the first network device can make a judgment based on the updated third information.

[0177] In some embodiments, the names of information, etc., are not limited to the names described in the embodiments. Terms such as "information", "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "domain", "field", "symbol", "symbol", "codebook", "codeword", "codepoint", "bit", "data", "program", and "chip" can be used interchangeably.

[0178] In some embodiments, "acquire," "get," "obtain," "receive," "transmit," "bidirectional transmission," and "send and / or receive" can be used interchangeably and can be interpreted as receiving from other entities, acquiring from protocols, acquiring from higher layers, obtaining through self-processing, or autonomous implementation. Protocols include, for example, at least one of the 3GPP protocol, Wi-Fi protocol, and audio and / or video protocols.

[0179] In some embodiments, terms such as “send,” “transmit,” “report,” “distribute,” “transfer,” “bidirectional transmission,” “send and / or receive” can be used interchangeably.

[0180] In some embodiments, terms such as "certain," "preset," "default," "set," "indicated," "a certain," "any," and "first" can be used interchangeably. "Certain A," "preset A," "default A," "set A," "indicated A," "a certain A," "any A," and "first A" can be interpreted as A pre-defined in a protocol or the like, or as A obtained through setting, configuration, or instruction, or as specific A, a certain A, any A, or first A, but are not limited thereto.

[0181] In step S2102, the first network device sends third information to the second network device.

[0182] In some embodiments, the first network device may send third information to the second network device via a third message, which is used to request a handover.

[0183] In some embodiments, there may be one or more second network devices. In other words, the first network device may send third information to multiple second network devices to prepare for access control.

[0184] For example, the source access network device initiates a handover and sends a handover request message HANDOVER REQUEST through the Xn interface, indicating to the target access network device the time when the AI-predicted measurement event meets the configuration conditions, and the probability of the AI-based handover prediction.

[0185] In some embodiments, the first network device may send the third information to the second network device via a fourth message, which is dedicated to sending the third information.

[0186] For example, the source access network device can indicate the predicted probability of AI-based handover to the target access network device in an existing handover message, such as in a HANDOVER REQUEST. Alternatively, a new message, such as an AI HANDOVER REQUEST, can be used to indicate the predicted probability of AI-based handover to the target access network device. The message names are merely illustrative and are not intended to limit the scope of this disclosure.

[0187] For example, the terminal reports information about measurement events predicted by AI, such as the time when the AI-predicted measurement event meets the configuration conditions and the corresponding accuracy of the AI ​​prediction.

[0188] In some embodiments, the time when the measurement event predicted by the model, as indicated in the third information sent by the first network device to the second network device, satisfies the configuration conditions may be a time provided by the terminal device, or it may be a time further determined by the first network device based on the time provided by the terminal device, or both the time provided by the terminal device and the time further determined by the first network device may be sent to the second network device.

[0189] In some embodiments, the first network device may send updated third information to the second network device so that the second network device can determine whether to perform cell handover based on the updated third information.

[0190] In step S2103, the second network device performs access control.

[0191] In some embodiments, the second network device may perform access control based on third information to determine whether to perform cell handover and to perform access control. The third information may be the initially transmitted third information or the third information that has been updated and retransmitted; this disclosure does not limit its scope.

[0192] In some embodiments, the second network device determines whether to perform a cell handover based on third information.

[0193] In some embodiments, the second network device may determine whether to perform a cell handover based on the following criteria: for a specific terminal, a handover is performed if the probability value is high, and not if the probability value is low; for multiple terminals, the cell handover is performed if the probability value of the terminal with the highest probability value is selected, or if the probability value meets certain conditions, and the others are not handed over. Alternatively, the decision to perform a cell handover may be based on the probability value and other criteria, such as the predicted levels of parameters like Mn and Mp.

[0194] In some embodiments, the second network device may determine whether to perform cell handover based on a probability value. For example, if the second network device determines to handover based on a probability value, it may send a handover request confirmation message; or if the second network device determines not to handover based on a probability value, it may send a cancel or refuse handover message; or if the second network device determines not to handover based on a probability value, it may take no action, and the first network device will also default not to perform cell handover if it does not receive any message.

[0195] In some embodiments, multiple second network devices that receive the third information determine whether to perform cell handover based on the third information, with one or more of them determining to perform cell handover and the other second network devices determining not to perform cell handover.

[0196] In some embodiments, the second network device performs access control based on third information.

[0197] For example, the target access network device performs access control based on information provided by the source access network device.

[0198] In some embodiments, the second network device may perform access control by adding the terminal device's identifier to the whitelist of allowed access, thereby enabling the terminal device to switch normally to the cell where the second network device is located.

[0199] In some embodiments, the second network device performs access control, which may involve reserving wireless resources and / or processing capabilities for the terminal device to ensure that the terminal device can switch to the second network device.

[0200] In some embodiments, the second network device performs access control by determining a first moment, which is the end time associated with at least one of the wireless resources and processing capabilities reserved by the second network device for the terminal device.

[0201] For example, the target access network device indicates to the source access network device the time information of the radio resources and / or processing capabilities reserved for the terminal. This time information is absolute time information, i.e., a single moment, such as GPS (Global Positioning System) time or UTC (Universal Time Coordinated) time. The target access network device only reserves radio resources and / or processing capabilities for the terminal up to this moment.

[0202] In some embodiments, the second network device performs access control by determining a first duration, which is the duration associated with at least one of the wireless resources and processing capabilities reserved by the second network device for the terminal device.

[0203] For example, the time information is duration information, and the time at which the target access network device reserves wireless resources and / or processing capabilities for the terminal is determined by the time when the target access network device sends the time information (or the source access network device receives the time information) and the duration information.

[0204] For example, as shown in the schematic diagram in Figure 4C, let t0 be the predicted handover time of the terminal. The target access network device determines, based on t0 and some margin, to reserve radio resources and / or processing capacity for the terminal up to time t2. Here, time t2 is the first time, and the time period from time t1 to time t2 is the first duration.

[0205] In some embodiments, the second network device performs access control, which may involve reserving wireless resources and / or processing capabilities for the terminal device and determining at least one of a first moment and a first duration.

[0206] In step S2104, the second network device sends the fourth information to the first network device.

[0207] In some embodiments, the fourth information instructs the second network device to determine whether to perform a cell handover.

[0208] In some embodiments, the fourth information includes an identifier assigned to the terminal device by the second network device and an identifier of the terminal device in the first network device.

[0209] In some embodiments, if the second network device determines to perform a cell handover based on the third information, it sends a fourth information to the first network device to instruct the second network device to determine to perform a cell handover.

[0210] In some embodiments, the fourth message sent by the second network device to the first network device may be an acceptance of a cell handover request.

[0211] In some embodiments, the name of the fourth information may be a switch request confirmation message, a confirmation of switch execution message, etc., and the carrier of the fourth information may be a fifth message, which is not limited in this disclosure.

[0212] For example, the target access network device provides a new RRC configuration in the HANDOVER REQUEST ACKNOWLEDGE message.

[0213] Step S2105: The second network device sends the second information to the first network device.

[0214] In some embodiments, the second information indicates time information related to at least one of the wireless resources and processing capabilities reserved by the second network device for the terminal device.

[0215] In some embodiments, the second information includes at least one of the following: a first moment, which is the end time associated with at least one of the wireless resources and processing capabilities reserved by the second network device for the terminal device; and a first duration, which is the duration associated with at least one of the wireless resources and processing capabilities reserved by the second network device for the terminal device.

[0216] In some embodiments, the second network device sending the second information to the first network device can be done through a first message, whereby the second network device determines to perform a cell handover. It is understood that when the second information is sent through the first message, the first message and the fourth message in step S2104 are the same message; that is, the second information and the fourth information are sent to the first network device through the same message.

[0217] For example, the target access network device may indicate to the source access network device, in an existing handover message, the timing information related to the radio resources and processing capabilities reserved for the terminal, such as in a HANDOVER REQUEST ACKNOWLEDGE.

[0218] In some embodiments, the second network device may send the second information to the first network device via a second message, which is dedicated to at least one of sending and receiving the second information. It is understood that when the second information is sent via a second message, the second message and the fourth message are different messages; that is, the second information and the fourth information are sent to the first network device via different messages.

[0219] For example, the target access network device can use a new message, such as AI HANDOVER REQUEST ACKNOWLEDGE, to indicate to the source access network device the timing information related to the radio resources and processing capabilities reserved for the terminal.

[0220] In some embodiments, the second network device sends time information related to at least one of the wireless resources and processing capabilities reserved for the terminal device to the first network device, so that the first network device knows that the terminal device needs to perform a handover before a first moment or that the terminal device needs to perform a handover within a first duration.

[0221] For example, as shown in Figure 4C, the target access network device can notify the source access network device at time t2.

[0222] For example, as shown in Figure 4C, the target access network device can notify the source access network device of the duration information. Let t1 be the time when the target access network device sends the duration information (or when the source access network device receives the duration information), then t2 = t1 + duration.

[0223] In some embodiments, step S2105 is optional, and this step may be omitted or replaced in different embodiments.

[0224] Step S2106: The first network device sends a handover command to the terminal device.

[0225] In some embodiments, the moment when the first network device sends a handover command to the terminal device may be the moment when the measurement events predicted by the model by the terminal device meet the configuration conditions.

[0226] In some embodiments, the moment when the first network device sends the handover command to the terminal device may be the moment when it receives the fourth information sent by the second network device.

[0227] For example, the timing of the source access network device sending the handover command is determined by the network implementation. For instance, the source access network device sends the handover command when the measurement event meets the configuration conditions (rather than when the measurement event predicted by the AI ​​meets the configuration conditions).

[0228] In some embodiments, the first network device sends a handover command to the terminal device to enable the terminal device to switch from the current serving cell to the cell corresponding to the second network device, thereby completing the cell handover.

[0229] In some embodiments, the first network device may send a handover command to the terminal device before a first moment, so that the terminal device can switch to the second network device before the first moment.

[0230] Step S2107: The second network device sends the first information to the first network device.

[0231] In some embodiments, the first information is used to cancel cell handover.

[0232] In some embodiments, the first information is used to cancel cell handover based on artificial intelligence (AI) models or AI function predictions. Cell handover is triggered by information related to cell handover predicted by AI models or AI functions.

[0233] In some embodiments, the first information is used to cancel a first type of cell handover, such as a cell handover triggered by an AI model or AI function prediction, or a cell handover triggered by actual parameters, which is not limited in this disclosure.

[0234] In some embodiments, after determining that a cell handover is to be performed, the second network device monitors the access of the terminal device before a first moment and / or within a first duration, and sends first information to the first network device if the terminal device has not switched to the second network device.

[0235] For example, the target access network device sends a message to the source access network device to cancel an AI-based handover, such as canceling a previously prepared AI-based handover.

[0236] For example, as shown in the schematic diagram in Figure 4A, the target access network device sends an AI HANDOVER CANCEL message to the source access network device to cancel the AI-based cell handover.

[0237] In some embodiments, the first information includes at least one of the following: the reason for canceling the cell handover; the identifier of the terminal device in the first network device; and the identifier of the terminal device in the second network device. It is understood that the second network device will cancel the cell handover when it determines that the terminal device has not performed a handover. Furthermore, the second network device will determine the reason for canceling the cell handover, which may include at least one of a network-related reason or a terminal device-related reason.

[0238] In some embodiments, the reason for canceling cell handover is, for example, a Radio Network Layer Cause, which can be a reason already defined in NR (e.g., Cell Not Available, No Radio Resources Available in Target Cell), or a newly defined reason, such as "UE Not Handovered in Time".

[0239] In some embodiments, the identifier of the terminal device in the first network device may, for example, be the Source NG-RAN node UE XnAP ID, which is assigned by the source access network device and used in Xn interface communication to uniquely identify the terminal in the source access network device.

[0240] In some embodiments, the identifier of the terminal device in the second network device may, for example, be the Target NG-RAN node UE XnAP ID, which is assigned by the target access network device and used in Xn interface communication to uniquely identify the terminal in the target access network device.

[0241] In some embodiments, step S2107 is optional. Accordingly, step S2107 is executed when the terminal device has not switched to the second network device, and step S2107 is not executed when the terminal device has switched to the second network device.

[0242] In step S2108, the second network device releases at least one of its wireless resources and processing capabilities.

[0243] In some embodiments, if the terminal device does not switch to the second network device before the first moment, the second network device releases at least one of the wireless resources and processing capabilities reserved for the terminal device.

[0244] In some embodiments, if the terminal device does not switch to the second network device within a first time period, the second network device releases at least one of the wireless resources and processing capabilities reserved for the terminal device.

[0245] For example, when a terminal device fails to switch to a second network device according to the time information of the reserved radio resources and / or processing capabilities, the target access network device deletes the radio resources and / or processing capabilities previously reserved for the terminal device, which is identified by the Source NG-RAN node UE XnAP ID and the Target NG-RAN node UE XnAP ID.

[0246] In the above embodiments, after determining to perform cell handover, the second network device sends the time information of the radio resources and / or processing capabilities reserved for the terminal device to the first network device, and / or cancels the cell handover based on model prediction when the terminal device has not switched to the second network device, and releases the radio resources and / or processing capabilities reserved for the terminal device to provide resources to other terminal devices, thereby making full use of resources and providing services to more terminal devices.

[0247] The communication method involved in the embodiments of this disclosure may include at least one of steps S2101 to S2108. For example, step S2101 may be implemented as a standalone embodiment, step S2102 may be implemented as a standalone embodiment, step S2101+S2102 may be implemented as a standalone embodiment, and steps S2101+S2102+S2103, S2101+S2102+S2103+S2104, S2101+S2102+S2103+S2104+S2106, and S2101+S2102+S2103+S2104+S2106 may also be implemented as standalone embodiments. Steps S2104+S2105+S2106, S2101+S2102+S2103+S2104+S2106+S2107, S2101+S2102+S2103+S2104+S2106+S2107+S2108, and S2101+S2102+S2103+S2104+S2105+S2106+S2107+S2108 can be implemented as independent embodiments, but are not limited thereto.

[0248] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0249] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0250] Step S3101: The second network device sends at least one of the first information and the second information to the first network device.

[0251] The first information is used to cancel cell handover, and the second information indicates time information related to at least one of the wireless resources and processing capabilities reserved for the terminal device, wherein the first network device is currently providing communication services to the terminal device.

[0252] Optionally, the alternative implementation of step S3101 can be found in the alternative implementation of step S2107 in Figure 2, as well as other alternative implementations involved in Figure 2, which will not be elaborated here.

[0253] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0254] In the above embodiments, the second network device may send the first information of canceling cell handover to the first network device and / or send the first network device time information related to at least one of the wireless resources and processing capabilities reserved for the terminal device, so as to avoid reserving resources for the terminal device for a long time, and to release the resources in a timely manner to provide them to other terminal devices, thereby achieving the purpose of making full use of resources.

[0255] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0256] The following are specific solutions proposed in the embodiments of this disclosure:

[0257] Option 1:

[0258] The target access network device (e.g., the target base station) sends a message to the source access network device (e.g., the source base station) to cancel the AI-based handover, such as canceling a previously prepared AI-based handover.

[0259] The target access network device sends an AI-based handover cancellation message (e.g., AI HANDOVER CANCEL) to the source access network device (message name is for example only), as shown in 4A.

[0260] The message contains the following:

[0261] The reason for sending the message (Cause), that is, the reason for canceling the AI-based handover, such as the Radio Network Layer Cause, can be a reason already defined in NR, such as Cell Not Available, No Radio Resources Available in Target Cell, or a newly defined reason, such as "UE Not Handovered in Time".

[0262] The terminal's identifier on the source access network device, such as the Source NG-RAN node UE XnAP ID. This identifier is assigned by the source access network device and used in Xn interface communication to uniquely identify the terminal within the source access network device.

[0263] The terminal's identifier on the target access network device, such as the Target NG-RAN node UE XnAP ID. This identifier is assigned by the target access network device and used in Xn interface communication to uniquely identify the terminal within the target access network device.

[0264] Upon receiving a cancellation message based on AI from the target access network device, the source access network device assumes that the target access network device will delete the radio resources and processing capabilities previously reserved for the terminal, which is identified by the Source NG-RAN node UE XnAP ID and the Target NG-RAN node UE XnAP ID.

[0265] Example 1:

[0266] An AI-based switching process is shown in 4B:

[0267] 1. The terminal reports information about measurement events predicted by AI, such as the time when the AI-predicted measurement events meet the configuration conditions.

[0268] Optionally, the alternative implementation of step 1 can be found in the alternative implementation of step S2101 in Figure 2.

[0269] 2. The source access network device initiates a handover and sends a handover request message HANDOVER REQUEST through the Xn interface.

[0270] Optionally, the alternative implementation of step 2 can be found in the alternative implementation of step S2102 in Figure 2.

[0271] 3. The target access network device performs access control.

[0272] Alternatively, the alternative implementation of step 3 can be found in the alternative implementation of step S2103 in Figure 2.

[0273] 4. The target access network device provides a new RRC configuration in the HANDOVER REQUEST ACKNOWLEDGE message.

[0274] Optionally, the alternative implementation of step 4 can be found in the alternative implementation of step S2104 in Figure 2.

[0275] 5. The target access network device did not detect the terminal performing a handover.

[0276] 6. The target access network device sends an AI HANDOVER CANCEL message to the source access network device to cancel the previously prepared AI-based handover.

[0277] Alternatively, the alternative implementations of steps 5 and 6 can be found in the alternative implementation of step S2107 in Figure 2.

[0278] Option 2:

[0279] The target access network device indicates to the source access network device the time information of the radio resources and processing capabilities reserved for the terminal.

[0280] The time information is absolute time information, i.e., a specific moment, such as GPS (Global Positioning System) time or UTC (Universal Time Coordinated) time. The target access network device reserves radio resources and processing capabilities for the terminal up to the stated moment. If the terminal does not switch to the target access network device before the stated moment, the target access network device will release the radio resources and processing capabilities reserved for the terminal.

[0281] The time information is duration information. The time at which the target access network device reserves wireless resources and processing capabilities for the terminal is determined by the time the target access network device sends the time information (or the time the source access network device receives the time information) and the duration information.

[0282] The target access network device can indicate the timing information of the radio resources and processing capabilities reserved for the terminal to the source access network device in an existing handover message, such as in a HANDOVER REQUEST ACKNOWLEDGE. Alternatively, the target access network device can use a new message, such as AIHANDOVER REQUEST ACKNOWLEDGE, to indicate the timing information of the radio resources and processing capabilities reserved for the terminal to the source access network device.

[0283] Example 2:

[0284] As shown in Figure 4C, let t0 be the predicted handover time for the terminal. The target access network device determines, based on t0 and some margin, that it will reserve radio resources and processing capacity for the terminal up to time t2. As mentioned earlier, one approach is for the target access network device to notify the source access network device of t2. Another approach is for the target access network device to notify the source access network device of the duration information. Let t1 be the time when the target access network device sends the duration information (or when the source access network device receives the duration information), then t2 = t1 + duration.

[0285] Alternatively, the optional implementation of Embodiment 2 can be found in the optional implementations of steps S2105 and S2108 in Figure 2.

[0286] In summary, this disclosure provides a method for the target access network device to handle reserved resources during an AI-based handover process. The target access network device can cancel the AI-based handover or notify the source access network device of the duration for which the target access network device reserves radio resources and processing capabilities for the terminal. Through this method, the target access network device only reserves necessary resources for AI-based handover, thus avoiding the need to constantly reserve resources for the terminal. Therefore, resources can be provided to other terminals, enabling full utilization of resources and providing services to more terminals.

[0287] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by the first network device (e.g., access network device, core network functional node, core network device, etc.) in any of the above methods.

[0288] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0289] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
