Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a cell handover method and related apparatus. Background Technology

[0002] In wireless communication scenarios, when an end user moves, the terminal needs to perform a connected-state handover within a cell. The network side can configure a handover threshold for the terminal, which then uses this threshold to determine whether to report a measurement report. The handover threshold determines the timeliness and stability of cell handover and is a crucial parameter in the connected-state handover scheme, requiring optimization.

[0003] The optimization techniques for handover thresholds are mainly implemented through the mobility robustness optimization (MRO) module or the mobility load balancing (MLB) module. The MRO module adjusts the handover threshold based on the success rate of handover to neighboring cells; the MLB module adjusts the handover threshold based on the load conditions of the source cell and neighboring cells.

[0004] While these two approaches can improve the handover success rate or make the load between cells more balanced, the single optimization method cannot guarantee that it can meet the needs of terminals to perform complex and diverse services. Summary of the Invention

[0005] This application provides a wireless communication method and related apparatus, the purpose of which is to enable the optimized switching threshold to adapt to diverse service requirements.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] In a first aspect, this application provides a wireless communication method, which may be executed by a terminal, or by a component (such as a circuit, chip, or chip system) configured in the terminal, or by a logic module or software capable of implementing all or part of the terminal's functions. This application does not limit the scope of this method.

[0008] A cell handover method includes: receiving a first message, the first message indicating a measurement configuration, the measurement configuration including a measurement object and a first handover threshold; and sending a measurement report or performing a cell handover based on a second handover threshold and a measurement result, wherein the second handover threshold is obtained by optimizing the first handover threshold based on the channel indicator requirements of services in a service priority list by a first model, and the measurement result is obtained by performing channel quality measurements on the measurement object based on the measurement configuration.

[0009] In the above technical solution, the terminal adjusts the first handover threshold by utilizing the channel index requirements corresponding to the services in the service priority list. This can optimize the first handover threshold from the perspective of channel quality requirements when multiple services are executed, ensuring that the optimized handover threshold can adapt to diverse service requirements.

[0010] In one possible implementation, the first model optimizes the first handover threshold by limiting it to an allowed adjustment range. This allowed adjustment range allows the terminal to adjust the handover threshold under network-side constraints, improving the reliability of the first handover threshold adjustment.

The monitoring report includes: channel indicator requirements for high-weight services, terminal location and capability information, the service weight and usage frequency, and / or the positive correlation between the service's weight and usage frequency, and / or the service's channel quality requirements. Informing the network side of the channel indicator requirements for high-weight services through the monitoring report can improve the accuracy of the network side's configuration of the first handover threshold.

[0014] In one possible implementation, the channel performance requirements of services in the service priority list are obtained by a service classification model based on the services executed by the terminal in the first time period.

[0015] In one possible implementation, the cell handover method further includes generating cell handover evaluation information, which indicates whether the cell handover is too early, too late, or appropriate.

[0016] In one possible implementation, the first model is trained based on user behavior data, channel performance requirements of services in the historical service priority list, and historical evaluation information of cell handover. The cell handover evaluation information is used as parameters for training the first model, which improves the training efficiency.

[0017] In one possible implementation, the measurement results are obtained by performing channel quality measurements on the measured object based on the measurement configuration, including: the measurement results are obtained by performing channel quality measurements on the measured object within the measurement interval based on the measurement configuration.

[0062] For example, Figure 1 A schematic diagram of the architecture of a communication system provided in an embodiment of this application is shown.

[0063] like Figure 1 As shown, the communication system includes a first device 100 and a second device 200.

[0064] The first device 100 can be a network-side device used to provide network communication functions. In some cases, it is also called a network device or network element. The network device can usually be a base station (including functional units of the base station, or a combination of functional units of the base station) or a core network unit. The core network unit can be a functional unit in the core network, including but not limited to authentication server function (AUSF) network elements, unified data management (UDM) network elements, network repository function (NRF) network elements, network exposure function (NEF) network elements, application function (AF) network elements, policy control function (PCF) network elements, access and mobility management function (AMF) network elements, session management function (SMF) network elements, user plane function (UPF) network elements, network data analytics function (NWDAF) network elements, etc.

[0066] Base stations can be macro base stations, micro base stations, pico base stations, small cells, relay stations, or balloon stations, etc. A base station can contain one or more co-located or non-co-located transmission reception points (TRPs). A base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. A base station can communicate with a terminal, or it can communicate with a terminal through a relay station. A terminal can communicate with multiple base stations using different technologies; for example, a terminal can communicate with a base station supporting LTE networks, or with a base station supporting 5G networks, and can even have dual connections with both LTE and 5G base stations.

[0067] The second device 200 can be a device that accesses the network, typically a terminal.

[0068] In this application embodiment, the terminal can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality (VR), augmented reality (AR), industrial control, self-driving, remote medical, smart grid, smart furniture, smart office, smart wearables, smart transportation, smart city, and smart home. The terminal can take various forms, such as mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality terminal devices, augmented reality terminal devices, wireless terminals in industrial control, vehicle-mounted terminal devices, wireless terminals in autonomous driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable terminal devices, and so on. Terminal equipment may also be referred to as a terminal, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication equipment, UE agent, or UE device, etc. A terminal can also be a fixed terminal or a mobile terminal.

[0069] In some embodiments, the communication system may also include other devices that communicate with the first device and / or the second device, which is not a limitation of this application.

[0070] In wireless communication scenarios, when an end user moves, the terminal needs to perform a connected-state handover within a cell. The network side can configure a handover threshold for the terminal, which then uses this threshold to determine whether to report a measurement report. The handover threshold determines the timeliness and stability of cell handover and is a crucial parameter in the connected-state handover scheme, requiring optimization.

[0071] The optimization techniques for handover thresholds are mainly implemented through the mobility robustness optimization (MRO) module or the mobility load balancing (MLB) module. The MRO module adjusts the handover threshold based on the success rate of handover to neighboring cells; the MLB module adjusts the handover threshold based on the load conditions of the source cell and neighboring cells.

[0072] While these two approaches can improve the handover success rate or make the load between cells more balanced, the single optimization method cannot guarantee that it can meet the needs of terminals to perform complex and diverse services.

[0073] In response to this, embodiments of this application provide a cell handover method that enables optimized handover thresholds to adapt to diverse service requirements.

[0074] Figure 2 An exemplary flowchart of the cell handover method provided in the embodiments of this application is shown.

[0075] like Figure 2 As shown, the cell handover method includes:

[0076] S201, The terminal detected a cell handover requirement.

[0077] The terminal can monitor the channel quality of the cell it is camping on. When the channel quality of the cell it is camping on is low, it indicates that a cell handover requirement has been detected.

[0078] For example, channel quality metrics may include one or more of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR).

[0079] Correspondingly, poor channel quality may include one or more of the following: RSRP values ​​are less than or equal to a first threshold, RSRQ values ​​are less than or equal to a second threshold, and SINR values ​​are less than or equal to a third threshold. The first, second, and third thresholds can be set.

[0080] If the terminal detects a cell handover requirement, it can execute the following step S202.

[0081] S202. The terminal sends a monitoring report to the network device, and the network device receives the monitoring report accordingly.

[0082] The monitoring report includes: channel indicator requirements for high-weight services, terminal location information, and capability information.

[0083] The services executed by the terminal can be configured with weights.

[0084] For example, the weight of the service can indicate the frequency of service use, and the frequency of service use is positively correlated; for another example, the weight of the service can also indicate the channel quality requirements of the service, and the weight value is positively correlated with the channel quality requirements of the service; for yet another example, the weight of the service can also indicate both the frequency of service use and the channel quality requirements, and the weight value is positively correlated with both the frequency of service use and the channel quality requirements.

[0085] The frequency of service usage can be determined based on how the terminal performs services over a period of time. Services with high weight indicate that they are the main services performed by the terminal over a period of time.

[0086] Channel quality requirements for a service can include its real-time performance requirements. A high-weighted service indicates a service with high real-time performance requirements. For example, gaming and voice calls require zero latency and are therefore high-weighted services. Web browsing, on the other hand, does not have high real-time performance requirements and may not be considered a high-weighted service.

[0087] High-weighted services can refer to services with weight values ​​greater than the fourth threshold, or the top K services among multiple services sorted by weight, where K can be an integer greater than 1, and the fourth threshold can be set.

[0088] Channel performance requirements, also known as channel quality requirements, include one or more of RSRP, RSRQ, and SINR. Service channel performance requirements indicate the general channel quality requirements for a terminal performing that service. For example, for a 1080p live streaming service, channel performance requirements might include RSRP greater than -109dBm and SINR greater than 0.6dBm; another example is for a gaming service, where channel performance requirements might include RSRP greater than -118dBm and SINR greater than 1dBm.

[0089] The channel index requirements for high-weight services are used to provide network devices with a reference for the channel quality requirements when the terminal performs the service. The network devices can determine the first handover threshold in step S203 based on the channel index requirements.

[0090] For example, the terminal's location information can be physical location, such as GPS, or it can be location indication information, such as physical cell identity (PCI) or cell global identifier (CGI).

[0091] The terminal's location information is used to provide the network device with the terminal's location in order to determine the target cell.

[0092] For example, the terminal's capability information may include: the frequency bands supported by the terminal and / or measurement gap information.

[0093] For example, the monitoring report may be included in (or carried on) a message in the data plane. This application does not limit the message carrying the monitoring report or the format of the monitoring report.

[0094] When the network device receives the monitoring report and determines that a cell handover is to be performed, step S203 can be executed.

[0095] Steps S201 and S202 can be optional steps. In some embodiments, the terminal may not execute steps S201 and S202, and the network device may actively send the first message to the terminal through step S203.

[0096] S203. The network device sends the first message to the terminal, and the terminal receives the first message accordingly.

[0097] The first message is used to indicate the configuration information of the measurement configuration, which includes the measurement object and the first switching threshold.

[0098] The measurement object is the target that the terminal device needs to measure, such as a list of available cells, which may include one or more cells.

[0099] The first handover threshold is a recommended value for the handover threshold provided by the network device. The first handover threshold is used to indicate the minimum standard for performing cell handover as determined by the network side. The first handover threshold may include the minimum standard of one or more of RSRP, RSRQ, and SINR.

[0100] Optionally, the configuration information for the measurement configuration may also include reporting configuration and / or measurement identifiers.

[0101] The report configuration is used to indicate the conditions and format for submitting measurement reports; the measurement identifier is used to indicate the binding relationship between the measurement object and the report configuration.

[0102] Alternatively, the configuration information of the measurement configuration may also include an allowed adjustment range, which is the range within which the first handover threshold can be adjusted. This allowed adjustment range enables the terminal to adjust the handover threshold under network-side constraints, improving the reliability of the first handover threshold adjustment.

[0103] For example, the first message could be radio resource control (RRC) signaling, but this is not a limitation.

[0104] S204. Based on the configuration information, the terminal performs channel quality measurement on the object being measured and obtains the measurement results.

[0105] For example, the measurement object is a list of available cells, which includes one or more cells.

[0106] For each beam included in each cell, the terminal performs measurements based on a reference signal to obtain the measurement result for that beam, such as one or more of RSRP, RSRQ, and SINR. Optionally, the measurement results of all or part of the beams included in a cell can be used as the measurement result for that cell. Further optionally, the measurement results of all or part of the beams included in a cell can be combined and then used as the measurement result for that cell. For example, the combining process may include: selecting the measurement results of the N beams with the best signal quality, calculating the average of the measurement results of all beams, etc., where N is an integer greater than or equal to 1. The measurement result of each cell in the available cell list can be used as the measurement result for the object being measured.

[0107] S205. The terminal uses the first model to optimize the first handover threshold based on the service priority list and the channel indicator requirements of the service, and obtains the adjustment amount of the handover threshold or the second handover threshold.

[0108] The first model can be exemplified as a switching threshold optimization model.

[0109] The service priority list includes multiple services, each with its own channel performance requirements. The details of these channel performance requirements are provided above and will not be repeated here.

[0110] Optionally, the business priority list may include multiple businesses belonging to different business types.

[0111] Optionally, multiple services in the service priority list can be sorted according to their degree of belonging to the primary service type. That is, the higher the degree to which a service belongs to the primary service type, the higher it is ranked.

[0112] For example, the main business type can be indicated by the business weight. The explanation of business weights can be found above and will not be repeated here.

[0113] In some embodiments, the service priority list includes multiple services and the channel performance requirements corresponding to each service, as well as a first handover threshold, which can be used as input parameters for a first model. Based on the input parameters, the first model can obtain an adjustment amount for the handover threshold or a second handover threshold. The second handover threshold is the adjusted handover threshold, and the difference between the first and second handover thresholds is the adjustment amount for the handover threshold.

[0114] In other embodiments, the configuration information of the measurement configuration may also include the allowed adjustment range. Correspondingly, one implementation of step S205 includes:

[0115] The terminal uses the first model, based on the service priority list and the channel performance requirements of the service, to optimize the first handover threshold within the allowed adjustment range, thereby obtaining either the adjustment amount of the handover threshold or the second handover threshold. In other words, the first handover threshold is limited to optimization within the allowed adjustment range.

[0116] The service priority list includes multiple services and the channel indicator requirements corresponding to each service. The first handover threshold and the allowed adjustment range can be used as input parameters for the first model. Based on the input parameters, the first model can obtain the adjustment amount of the handover threshold or the second handover threshold.

[0117] In this embodiment, the terminal adjusts the first handover threshold using the multiple services included in the service priority list and the channel indicator requirements corresponding to each service. This can optimize the first handover threshold from the perspective of channel quality requirements when multiple services are executed, ensuring that the optimized handover threshold can adapt to diverse service requirements and improving the robustness of the cell handover scheme.

[0118] Furthermore, by using the first model to optimize the switching threshold, without relying on human experience, the problems of long optimization time, inefficiency, and high cost can be avoided. It can also avoid the problem of poor optimization results due to insufficient human experience.

[0119] S206. Based on the second handover threshold and measurement results, the terminal sends a measurement report to the network device or performs cell handover.

[0120] In some embodiments, if the measurement result is greater than or equal to the second handover threshold, it indicates that the channel quality of the available cell configured in the configuration information is good, and cell handover can be performed. Correspondingly, the terminal can send a measurement report to the network device, so that the network device can decide whether to perform cell handover based on the measurement report. Alternatively, the terminal can also actively initiate a cell handover process to perform cell handover.

[0121] In this embodiment, sending a measurement report to the network device based on the second handover threshold and the measurement results affects the timing of the measurement report submission, which helps reduce the uploading of redundant data. Furthermore, the terminal sending the measurement report or performing cell handover based on the optimized handover threshold can also improve the success rate of cell handover.

[0122] For example, a terminal can report a measurement report based on the conditions and format specified in the report configuration instructions. This embodiment does not limit the message carrying the measurement report, the format of the measurement report, or its content.

[0123] In some embodiments, the measurement report may also include an adjustment amount for the handover threshold and / or a second handover threshold. Thus, the network device can optimize the first handover threshold for the next configuration information configuration based on the adjustment amount of the handover threshold or the second handover threshold, and can also optimize the allowed adjustment range for the next configuration information configuration.

[0124] In some embodiments, the terminal determines the channel indicator requirements for the high-weighted services proposed in step S202 in the following ways:

[0125] S11. The terminal uses a service classification model to profile the services of a historical time period, and generates a service priority list, service weights, and channel indicator requirements.

[0126] For example, a historical time period may include one or more time periods. Data on services performed by the terminal during a historical time period can be used as input parameters for a service classification model. The service classification model uses these input parameters to create a profile, resulting in a service priority list, service weights, and channel indicator requirements. Explanations of the service priority list, service weights, and channel indicator requirements can be found above and will not be repeated here.

[0127] For example, data on services performed by a terminal during a historical time period can indicate the type of service performed by the terminal, the time, channel quality, etc.

[0128] The service priority list and channel indicator requirements obtained by the terminal can also be used to train the first model.

[0129] S12. The terminal filters out high-weight services from the service priority list based on the service weight and obtains the channel indicator requirements of the high-weight services.

[0130] For details on high-weight business operations, please refer to the previous text; they will not be repeated here.

[0131] In some embodiments, the service classification model may be pre-configured locally on the terminal, or it may be obtained by the terminal requesting it from the network device.

[0132] For example, a terminal requests a service classification model from a network device, which includes: the terminal sending a request message to the network device, the request message being used to request a model, and the network device responding to the request message by sending a service classification model to the terminal.

[0133] Optionally, the request message can be RRC signaling, but this is not a limitation.

[0134] In some embodiments, the first model proposed in step S205 can be obtained by the terminal training an initial model. For example, the initial model can be pre-configured locally on the terminal, or it can be obtained by the terminal requesting it from a network device.

[0135] For example, the implementation of a terminal requesting the initial model of the first model from a network device includes:

[0136] S21. The terminal sends a second message to the network device. Correspondingly, the network device receives the second message. The second message is used to request the initial model of the first model.

[0137] For example, after a terminal camps on a network device's cell, the terminal can send a second message to the network device to request a model.

[0138] As another example, the second message can be the same as the request message for the request service classification model. In this way, the terminal can implement the initial model of the request service classification model and the first model based on a single message, reducing signaling overhead.

[0139] Of course, the second message may also be a different message from the request message of the request business classification model, and this application does not limit this.

[0140] For example, the second message could also be an RRC signaling message, but this is not a limitation.

[0141] S22. The network device sends a third message to the terminal. Correspondingly, the terminal receives the third message, which includes the initial model of the first model.

[0142] For example, a third message can be a data plane message, but this is not a limitation.

[0143] In the case where the second message is used to request the initial model and business classification model of the first model, the third message may include the initial model and business classification model of the first model.

[0144] After obtaining the initial model of the first model, the terminal can train the first model to achieve convergence. For example, the convergence condition may include the loss function's rate of change falling below a threshold.

[0145] In some embodiments, the method by which the terminal trains the initial model of the first model includes:

[0146] The terminal trains the initial model of the first model based on user behavior data, channel indicator requirements of services in the historical service priority list, and historical evaluation information of cell handover, thus obtaining the first model.

[0147] For example, user behavior data includes user trajectory data and data on user performance at different time periods.

[0148] User trajectory data is used to describe the user's movement behavior in physical space.

[0149] Service data can indicate the type of service executed by the terminal, the time, channel quality, etc.

[0150] Optionally, the service performed by the user is a call service, and the data used by the user to perform the service may include communication data.

[0151] After training, the initial model of the first model can achieve the following: based on the channel index requirements of the input service, optimize the input handover threshold to obtain a new handover threshold, or an adjustment amount of the handover threshold.

[0152] Examples of scenarios where a terminal moves within a cell and performs cell handover include normal handover scenarios, condition-based handover scenarios, and inter-frequency cell handover scenarios. The following combines... Figures 3 to 5 This paper introduces cell handover methods in three application scenarios.

[0153] In the following text, the source base station is the base station to which the terminal is currently connecting and serving. Before the cell handover command is issued and executed, all data and control signaling of the terminal are transmitted to the core network through this source base station. The target base station is the base station to which the terminal plans to hand over and establish a new connection.

[0154] Figure 3 An exemplary flowchart of a cell handover method in a normal handover scenario is shown.

[0155] like Figure 3 As shown, the cell handover method provided in this embodiment includes:

[0156] S301. The terminal uses a service classification model to profile services over a historical period, generating a service priority list, service weights, and channel indicator requirements.

[0157] The description of step S301 can be found in the description of step S11 above, and will not be repeated here.

[0158] The service classification model can be pre-configured by the terminal or obtained by the terminal from the source base station. See the previous text for further details, which will not be repeated here.

[0159] S302. The terminal uses user behavior data, service priority list, and service channel indicators to train an initial model for handover threshold optimization.

[0160] The explanation of step S302 can be found in the previous text and will not be repeated here.

[0161] S303. When the terminal detects a cell handover requirement, it sends a monitoring report to the source base station, and the source base station receives the monitoring report.

[0162] The monitoring report includes: channel metrics for high-weighted services, terminal location information, and capability information.

[0163] For example, the terminal's capability information may include: the frequency bands supported by the terminal, which the source base station uses to determine the cells in which the terminal can camp.

[0164] For details on channel metrics for high-weighted services and terminal location information, please refer to step S202; these details will not be repeated here.

[0165] In some embodiments, after receiving a monitoring report, the source base station may initiate a handover preparation process to the target base station. The handover preparation process includes: the source base station sending a handover request (HO request) to the target base station; the target base station receiving the HO request and making an admission control decision based on its own load; and when deciding to grant admission, replying to the source base station with HO permission information.

[0166] S304. The source base station sends the measurement configuration information to the terminal, and the terminal receives the corresponding configuration information.

[0167] The configuration information includes the measurement object, report configuration, measurement identifier, first switching threshold, and allowed adjustment range. The allowed adjustment range can be optional content in the configuration information.

[0168] For example, the configuration information for the measurement configuration may be included in a message carrying permission HO information.

[0169] For details regarding the measurement object, report configuration, measurement identifier, first switching threshold, and allowed adjustment range, please refer to step S203; these details will not be repeated here.

[0170] S305. The terminal measures the neighboring cells of the target base station based on the configuration information.

[0171] The measurement objects in the measurement configuration information include the cells under the target base station, which are adjacent cells of the terminal camp cell (i.e., the source cell).

[0172] For a description of step S305, please refer to the previous step S204, which will not be repeated here.

[0173] S306. The terminal uses an optimization model to optimize the first handover threshold based on the service priority list and the channel indicators of the service, and obtains the adjustment amount of the handover threshold or the second handover threshold. The optimization range is limited to the allowed adjustment range.

[0174] The explanation of step S306 can be found in step S205 above, and will not be repeated here.

[0175] The optimized model is the first model, which can be obtained by training the initial model of the first model on the terminal. This initial model can be pre-configured by the terminal or obtained by the terminal from the source base station. For details, please refer to the preceding text; they will not be repeated here.

[0176] S307. Based on the second handover threshold and the measurement results, the terminal sends a measurement report to the source base station. Correspondingly, the source base station receives the measurement report.

[0177] The measurement report includes the adjustment amount of the switching threshold and / or the second switching threshold.

[0178] For an explanation of step S307, please refer to the previous step S206, which will not be repeated here.

[0179] S308, the source base station determines whether to perform cell handover.

[0180] For example, the source base station decides whether to perform a cell handover based on the measurement report, the target base station's load status, and network policies. If the source base station decides not to handover, it maintains the connection with the terminal, notifies the target base station to cancel the HO preparation state, and searches for the next target base station for handover. The source base station may execute the following step S309 if it decides to handover.

[0181] S309. The source base station sends a handover request to the target base station. Correspondingly, the target base station receives the handover request.

[0182] For example, the handover request sent by the source base station may also include the terminal context.

[0183] S310. The target base station sends a handover command to the terminal through the source base station. Correspondingly, the terminal receives the handover command.

[0184] For example, after receiving a handover request, the target base station can reply with an access permission message to the source base station. This access permission message may include a handover command sent by the target base station to the terminal. Correspondingly, upon receiving this message, the source base station forwards the handover command to the terminal, which may indicate the target cell to be accessed.

[0185] S311. The terminal disconnects from the source cell and synchronizes with the target cell to complete random access.

[0186] After receiving the handover command, the terminal can disconnect from the source cell and synchronize with the target cell to complete random access.

[0187] After the terminal completes access to the target cell, the target base station can execute steps S312 and S313. The execution order of the two steps is not restricted.

[0188] S312, The path for the target base station to update data to the network elements of the core network.

[0189] For example, the network element includes: AMF and / or UPF.

[0190] S313, The target base station notifies the source base station to release the terminal context.

[0191] S314. Monitor the service completion status after the terminal switch and generate an evaluation of this switch.

[0192] For example, the evaluation information from this cell handover evaluation is used to indicate whether the cell handover is too early, too late, or appropriate.

[0193] Optionally, if after the terminal completes the cell handover, it is clear that there is no significant fluctuation in network latency and download speed, and the impact on current services is minimal, then the timing of this cell handover is appropriate; if it is found that the channel quality deteriorates after the cell handover and a cell handover requirement is detected again, then the cell handover is too early; if a T310 timeout or T304 timeout is detected, then the cell handover is too late.

[0194] This evaluation information can be used to further optimize the first model, i.e., the threshold switching optimization model.

[0195] S315, Adjustment amount of the source base station collection handover threshold or the second handover threshold.

[0196] The source base station can collect the adjustment amount of the handover threshold or the second handover threshold reported by the terminal in step S307, and use it to optimize the first handover threshold and the allowed adjustment range in the subsequent configuration information.

[0197] Figure 4 An exemplary flowchart of a cell handover method based on conditional handover scenarios is shown.

[0198] like Figure 4 As shown, the cell handover method provided in this embodiment includes:

[0199] S401. The terminal uses a service classification model to profile services over a historical period, generating a service priority list, service weights, and channel indicators.

[0200] The description of step S401 can be found in the aforementioned step S11, and will not be repeated here.

[0201] The service classification model can be pre-configured by the terminal or obtained by the terminal from the source base station. See the previous text for further details, which will not be repeated here.

[0202] S402. The terminal uses user behavior data, service priority list, and service channel indicators to train an initial model for handover threshold optimization.

[0203] The explanation of step S402 can be found in the previous text and will not be repeated here.

[0204] S403: When the terminal detects a cell handover requirement, it sends a monitoring report to the source base station, and the source base station receives the monitoring report.

[0205] The monitoring report includes: channel metrics for high-weighted services, terminal location information, and capability information.

[0206] For example, the terminal's capability information may include: the frequency bands supported by the terminal, which the source base station uses to determine the cells in which the terminal can camp.

[0207] For details on channel metrics for high-weighted services and terminal location information, please refer to step S202; these details will not be repeated here.

[0208] S404. The source base station sends a conditional handover request to the target base station. Correspondingly, the target base station receives the conditional handover request.

[0209] For example, a condition switching request may include a terminal context.

[0210] As another example, a conditional handover request can be used to request access to a group of target cells, which may belong to the same target base station or different target base stations. If a group of target cells belongs to different target base stations, the source base station can send conditional handover requests to multiple target base stations.

[0211] S405. The target base station sends an access consent message to the source base station. Correspondingly, the source base station receives the access consent message.

[0212] After receiving the conditional handover request, the target base station performs access control based on its own load. If it agrees to the access, the target base station returns an access agreement message to the source base station.

[0213] S406. The source base station sends measurement configuration information to the terminal. Correspondingly, the terminal receives the configuration information.

[0214] After receiving the acceptance message, the source base station selects a suitable target cell for the terminal and generates a cell set. The source base station then sends the CHO configuration information to the UE. This configuration information includes the target cell set, reporting configuration, measurement identifier, first handover threshold, and allowed adjustment range. The allowed adjustment range can be optional content from the configuration information.

[0215] Optionally, the configuration information may also include time-frequency domain resources configured by the network side for the target cell, so that when the terminal decides to switch to a target cell, it can use the time-frequency domain resources configured by the target cell to initiate random access.

[0216] For details regarding the measurement object, report configuration, measurement identifier, first switching threshold, and allowed adjustment range, please refer to step S203; these details will not be repeated here.

[0217] S407. The terminal measures the target cell based on the configuration information.

[0218] The explanation of step S407 can be found in step S204 above, and will not be repeated here.

[0219] S408. The terminal optimization model optimizes the first handover threshold based on the service priority list and the service channel indicators to obtain the adjustment amount of the handover threshold or the second handover threshold. The optimization range is limited to the adjustment range.

[0220] The explanation of step S408 can be found in step S205 above, and will not be repeated here.

This initial model can be pre-configured by the terminal or obtained by the terminal from the source base station. For details, please refer to the preceding text; they will not be repeated here.

[0222] S409. The terminal compares the measurement results with the second switching threshold.

[0223] After receiving the configuration, the terminal will simultaneously monitor the signal quality of the serving cell and all target cells, and calculate in real time whether any target cell meets the trigger condition, that is, the measurement result of the target cell is greater than or equal to the second handover threshold.

[0224] Once the terminal determines that the measurement result of the target cell is greater than or equal to the second handover threshold, steps S410 and S411 are executed. The execution order of the two steps is not restricted.

[0225] S410, The terminal sends the adjustment amount of the handover threshold and / or the second handover threshold to the source base station. Correspondingly, the source base station receives the adjustment amount of the handover threshold and / or the second handover threshold.

[0226] S411. The terminal disconnects from the source cell and synchronizes with the target cell to complete random access.

[0227] Once the terminal determines that the triggering conditions for a target cell have been met, it will automatically initiate the handover process and directly access the cell using the resources pre-configured by the network, without needing to apply to the network or wait for commands.

[0228] After the terminal completes access to the target cell, the target base station can execute steps S412 and S413. The execution order of the two steps is not restricted.

[0229] S412, The data update path from the target base station to the network elements of the core network.

[0230] For example, the network element includes: AMF and / or UPF.

[0235] Figure 5 An exemplary flowchart illustrates the cell handover method in a multi-frequency cell handover scenario.

[0236] like Figure 5 As shown, the cell handover method provided in this embodiment includes:

[0237] S501: The terminal uses a service classification model to profile services over a historical period, generating a service priority list, service weights, and channel indicators.

[0238] The description of step S501 can be found in the aforementioned step S11, and will not be repeated here.

[0239] The service classification model can be pre-configured by the terminal or obtained by the terminal from the source base station. See the previous text for further details, which will not be repeated here.

[0240] S502. The terminal uses user behavior data, service priority list, and service channel indicators to train an initial model for handover threshold optimization.

[0248] S506. The source base station sends measurement configuration information to the terminal. Correspondingly, the terminal receives the configuration information.

[0249] Configuration information includes a list of neighboring cells across different frequencies, report configuration, measurement identifier, measurement gap information, first handover threshold, and allowed adjustment range.

[0250] S507: Based on the configuration information, the terminal suspends the transmission and reception of the source base station serving cell during the measurement interval and performs measurements on the inter-frequency base station cell.

[0251] For an explanation of step S507, please refer to the previous step S204, which will not be repeated here.

[0252] S508, the terminal optimization model optimizes the first handover threshold based on the service priority list and the service channel indicators to obtain the adjustment amount of the handover threshold or the second handover threshold. The optimization range is limited to the adjustment range.

[0253] For an explanation of step S508, please refer to the previous step S205, which will not be repeated here.

[0254] The optimized model is the first model, which can be obtained by training the initial model of the first model on the terminal. This initial model can be pre-configured by the terminal or obtained by the terminal from the source base station. For details, please refer to the preceding text; they will not be repeated here.

[0255] S509. Based on the second handover threshold and the measurement results, the terminal sends a measurement report to the source base station, and the source base station receives the measurement report.

[0256] Measurement report, including the adjustment amount of the switching threshold and / or the second switching threshold.

[0257] The explanation of step S509 can be found in step S206 above, and will not be repeated here.

[0258] S510, the source base station determines whether to perform cell handover.

[0259] For example, the source base station decides whether to perform a cell handover based on the measurement report, the target base station's load status, and network policies. If the source base station decides not to handover, it maintains its connection with the terminal and searches for the next target base station to handover to. The source base station may execute the following step S511 when it decides to handover.

[0260] S511. The source base station sends a handover request to the target base station. Correspondingly, the target base station receives the handover request.

[0261] For example, a condition switching request may include a terminal context.

[0262] S512: The target base station sends a handover command to the terminal through the source base station. Correspondingly, the terminal receives the handover command.

[0263] S513: The terminal disconnects from the source cell, synchronizes with the target cell, and completes random access.

[0269] S517, Adjustment amount of the source base station collection handover threshold or the second handover threshold.

[0270] The descriptions of steps S516 and S517 can be found in steps S314 and S315, and will not be repeated here.

[0271] Figure 6 An exemplary schematic diagram illustrates the process of training the first model on a terminal and using the first model.

[0272] like Figure 6 As shown, training the first model on the terminal and using the first model include:

[0273] S601, Terminal collects data.

[0274] For example, the data collected by the terminal includes user behavior data at different time periods, and may also include network latency and upload / download speeds, etc.

[0275] Optionally, user behavior data at different time periods includes: user trajectory data and data on user service execution at different time periods. User trajectory data describes the user's movement behavior in physical space. Service data can indicate the type of service executed by the terminal, the time, channel quality, etc.

[0276] S602, The terminal preprocesses the data.

[0277] For example, preprocessing includes at least one of the following: data cleaning, removing some noisy data with less impact, and retaining unique values ​​for duplicate data.

[0278] S603, The terminal determines abnormal values ​​in the data.

[0279] For example, outliers are data points that differ significantly from the average value of data of the same type. If a data point contains outliers, it is considered invalid and deleted; if the data does not contain outliers, it is considered valid and used to train the optimization model (the initial model of the first model).

[0280] In some embodiments, the data includes outliers, but if the outliers are critical data, then the data needs to be replaced with the average of the normal data, and the replaced data should be retained.

[0281] For example, if the data is for business purposes and the outlier is an abnormal network speed, then the outlier is considered a critical data point. In this case, the outlier is replaced with the average value of the normal data and retained.

[0282] S604: The terminal trains and optimizes the model based on effective data.

[0283] The terminal can divide the effective data into a training set and a test set. The training set is used to train the optimization model, and the test set is used as input to the service classification model to obtain the channel indicator requirements of the services in the service priority list. Then, the trained optimization model optimizes the first handover threshold based on the channel indicator requirements of the services in the service priority list to obtain the second optimization threshold or the adjustment amount of the handover threshold.

[0284] The terminal uses a training set to train the optimization model. The machine learning model learns the switching trigger threshold optimization behavior autonomously from the training set, thus determining the machine learning-based switching threshold optimization model.

[0285] After the optimization model is trained, if the terminal moves during the execution of services and there is a need for cell handover, the handover threshold can be optimized based on the priority model, i.e., step S605 is executed.

[0286] S605, Terminal generates handover threshold optimization indicators.

[0287] The switching threshold optimization metric can refer to the adjustment amount of the switching threshold or the second switching threshold.

[0288] The terminal obtains the handover threshold optimization index based on the priority model. The implementation method includes the aforementioned step S205. Please refer to the previous text for the explanation, which will not be repeated here.

[0289] S606 The terminal will determine the switching threshold optimization index and the relevant index in the measurement report.

[0290] For example, the relevant indicators in the measurement report refer to the measurement results obtained by the terminal based on the configuration information for channel quality measurement.

[0291] If the indicator meets the measurement report reporting standard, that is, the measurement result is greater than or equal to the second switching threshold, the terminal executes step S607; if the indicator does not meet the measurement report reporting standard, that is, the measurement result is less than the second switching threshold, the terminal executes step S608.

[0292] S607, Terminal uploads measurement report.

[0293] S608, the terminal does not upload measurement reports.

[0294] Figure 7 This is a schematic block diagram of a communication device provided in an embodiment of this application.

[0295] like Figure 7 As shown, the communication device 700 may include a communication module 720. The communication module 720 can implement corresponding communication functions, which can be internal communication functions of the communication device 700 or communication functions between the communication device 700 and other devices. Optionally, the communication module 720 may also be referred to as a communication interface, transceiver module, or transceiver unit.

[0298] In one possible design, the communication device 700 may correspond to the terminal in the above method embodiments or a component (such as a circuit, chip, or chip system) configured in the terminal. The communication device 700 can be used to execute the steps or processes performed by the terminal in any of the above method embodiments.

[0299] For example, the communication module 720 is used to receive a first message, which indicates a measurement configuration, including a measurement object and a first handover threshold; based on a second handover threshold and the measurement result, it sends a measurement report or performs a cell handover, wherein the second handover threshold is obtained by optimizing the first handover threshold based on the channel indicator requirements of services in the service priority list by a first model, and the measurement result is obtained by performing channel quality measurement on the measurement object based on the measurement configuration.

[0300] For example, the first model optimizes the first switching threshold to be limited to the allowed adjustment range.

[0301] For example, the allowed adjustment range includes the measurement configuration.

[0302] For example, the measurement report may also include a second switching threshold and / or the difference between the first and second switching thresholds.

[0303] For example, the communication module 720 is also used to send a monitoring report when a cell handover requirement is detected. The monitoring report includes: channel indicator requirements for high-weight services, terminal location and capability information, the weight of the service and the frequency of service use, and / or the positive correlation between the channel quality requirements of the service and the service.

[0304] For example, the channel indicator requirements for services in the service priority list are obtained by the service classification model based on the services executed by the terminal in the first time period.

[0305] For example, the processing module 710 is used to generate evaluation information for cell handover, which indicates whether the cell handover is too early, too late, or appropriate.

[0306] For example, the first model is trained based on user behavior data, channel indicator requirements of services in the historical service priority list, and historical evaluation information of cell handover.

[0307] For example, the measurement results are obtained by performing channel quality measurements on the measurement object based on the measurement configuration, including: the measurement results are obtained by performing channel quality measurements on the measurement object within the measurement interval based on the measurement configuration.

[0308] For example, the communication module 720 is also used to send a second message requesting the initial model of the first model; and to receive a third message including the initial model of the first model.

[0309] The above are merely examples; for detailed steps or procedures, please refer to the descriptions in the foregoing embodiments.

[0311] For example, the communication module 720 is used to send a first message indicating a measurement configuration, which includes a measurement object and a first handover threshold; receive a measurement report or perform a cell handover in response to a cell handover instruction from a terminal, wherein the measurement report and the cell handover instruction from the terminal are obtained based on a second handover threshold and measurement results, wherein the second handover threshold is obtained by optimizing the first handover threshold based on the channel indicator requirements of services in the service priority list by a first model, and the measurement results are obtained by performing channel quality measurements on the measurement object based on the measurement configuration.

[0312] For example, the first model optimizes the first switching threshold to be limited to the allowed adjustment range.

[0313] For example, the allowed adjustment range includes the measurement configuration.

[0317] For example, the channel indicator requirements for services in the service priority list are obtained by the service classification model based on the services executed by the terminal in the first time period.

[0318] For example, the first model is trained based on user behavior data, channel indicator requirements of services in the historical service priority list, and historical evaluation information of cell handover.

[0319] For example, the measurement results are obtained by performing channel quality measurements on the measurement object based on the measurement configuration, including: the measurement results are obtained by performing channel quality measurements on the measurement object within the measurement interval based on the measurement configuration.
