[0093] Currently, artificial intelligence (AI) and machine learning (ML) technologies have been introduced into some important scenarios in the field of mobile communications, such as network energy saving, load balancing, and mobility optimization. By analyzing and automatically processing collected data to output prediction results or corresponding strategies, they help to better improve network management and user experience. Figure 1 An example diagram of the functional framework of the AI / ML model is shown in FIG. Figure 1 As shown, AI / ML model training (Model Training) is performed through the collected data, and the AI / ML model is used to obtain prediction results or inference strategies (Inference).

[0094] The Data Collection module provides input data for model training and inference. This input data includes measurement data from terminals and various network elements, feedback data from Actor modules, and output data from AI / ML models. The Data Collection module only provides raw data and does not require specialized data preparation (such as data cleaning, formatting, and conversion) for different AI / ML algorithms.

[0095] The model training module is responsible for training, testing, and validating AI / ML models, generating metrics for model performance. It includes data preparation and model deployment / update functions. Data preparation organizes the training data provided by the data acquisition module (data cleaning, data formatting, data conversion, etc.); model deployment / update deploys trained, tested, and validated AI / ML models to the model inference module.

[0096] The model inference module provides inference output (prediction or decision) for the AI / ML model and provides model performance feedback to the model training module. The model inference module provides model performance feedback, which can be used to verify AI / ML model performance.

[0097] The model inference module also has the function of data preparation, which is used to organize the inference data provided by the data acquisition module (data cleaning, data formatting, data conversion, etc.).

[0098] The Actor module is used to initiate corresponding actions after receiving the inference output (prediction or decision) from the model inference module. The Execution module can also feedback the results to the Data Collection module, which can be used for AI / ML model training, inference, or performance testing.

[0099] Quality of Experience (QoE) refers to users' subjective perception of the quality and performance of an application or service. Some QoE metrics can be expressed through measurement indicators, such as latency, buffering time, and corruption duration. Therefore, QoE metrics are divided into two parts: subjective and objective. The subjective part is evaluated using the Mean Opinion Score (MOS), while the objective part is evaluated using measurable indicators. Currently, research focuses on the objective part.

[0100] Traditional QoE features involve the network configuring terminals / user equipment (UE) to report QoE measurement results collected by the application layer. The network (e.g., the QoE server) analyzes these QoE measurement results and adjusts the relevant configuration and parameters of the service or application to improve the user's QoE. Therefore, network configuration optimization for services / applications is performed only after the QoE measurement results have fluctuated significantly, indicating that the user's QoE has deteriorated.

[0101] AI / ML models have the ability to predict and make decisions. If combined with traditional QoE features, for example, they can form decisions before the user experience deteriorates and adjust relevant configurations and parameters in advance or in a timely manner. However, the current solution for combining AI / ML technology with QoE features in existing technologies is to use AI / ML technology to optimize other user performance (for example, handover success rate in mobility), which may have an indirect effect on improving user QoE. However, the fundamental purpose of existing technologies is not to optimize user QoE, so the improvement effect is limited (because QoE is an application layer indicator). In particular, existing technologies cannot maintain stable QoE of terminals during mobility.

[0102] In summary, existing technical solutions have the problem of large fluctuations in the value of the QoE indicator and unstable QoE, especially the inability to maintain stable QoE during the movement of the terminal.

[0103] Based on this, in various embodiments of the present application, the second base station sends first information to the first base station, and the first base station receives the first information sent by the second base station; wherein, the first information is used to indicate the first value of the QoE indicator of the first cell of the second base station, and / or, to indicate whether the first cell of the second base station can provide a QoE indicator that meets the first requirement; the first cell represents the candidate cell that the first base station predicts the terminal can access; the first requirement represents the requirement of the continuous first service and / or first application and / or first business in the terminal for the QoE indicator; the first information is used for the first base station to determine the target cell to be switched by the terminal. In the above scheme, the first base station can determine the first cell that can provide the QoE indicator that meets the first requirement based on the first information, so as to determine the target cell of the terminal in the determined first cell, so as to keep the QoE stable during the movement of the terminal.

[0104] The present application will be described in further detail below with reference to the accompanying drawings and embodiments.

[0105] The embodiment of the present application provides a handover method, which is applied to a first base station. The first base station can be understood as a source base station, and the base station can also be called a network device. Figure 2 As shown, the method includes:

[0106] Step 201: Receive first information sent by a second base station.

[0107] The first information is used to indicate a first value of a QoE indicator of a first cell of the second base station, and / or to indicate whether the first cell of the second base station can provide a QoE indicator that meets a first requirement; the first cell represents a candidate cell that the first base station predicts the terminal can access; the first requirement represents the requirement of the continuous first service and / or first application and / or first business in the terminal for the QoE indicator; the first information is used for the first base station to determine a target cell to which the terminal is to be switched.

[0108] Here, the first base station can predict, based on the terminal's motion trajectory, candidate cells accessible to the terminal to obtain the first cell; determine the candidate base station to which the first cell belongs to obtain the second base station; the number of first cells is greater than or equal to 1, and the number of second base stations is greater than or equal to 1. The terminal's serving cell belongs to the first base station, and the terminal's motion trajectory can be obtained from a database or predicted based on historical data and / or location information of the terminal.

[0109] When the first base station determines the second base station, it can instruct the second base station to feedback the first information and receive the first information fed back by the second base station. It can also request the first information from the second base station. For example, the first base station can send a first request to the second base station and receive a first response to the first request returned by the second base station. The first request is used to request the first information. The first request can carry the QoE indicator and / or the identifier of the first cell, and the first response carries the first information. The first value of the QoE indicator indicated by the first information can be predicted by the second base station or other equipment, for example, using an AI model or an ML model, or based on historical data. In other words, the first value of the QoE indicator can be understood as the predicted value of the QoE indicator.

[0110] A QoE indicator can be understood as a QoE indicator corresponding to a first service and / or first application and / or first service that persists in a terminal. A first service can be understood as a service that persists during a cell handover of the terminal, a first application can be understood as an application that persists during a cell handover of the terminal, and a first service can be understood as a service that persists during a cell handover of the terminal. A first service can correspond to at least one QoE indicator, and the QoE indicators corresponding to different first services can be the same or different. A first application can correspond to at least one QoE indicator, and the QoE indicators corresponding to different first applications can be the same or different. A first service can correspond to at least one QoE indicator, and the QoE indicators corresponding to different first services can be the same or different. The QoE indicators and the number of QoE indicators corresponding to different services, different first applications, and different first services can be at least partially the same or completely different. QoE indicators can include at least one of the following: latency, smoothness, clarity, buffering duration, and buffer size. Latency includes initial playout delay.

[0111] The first requirement can be predicted by the first base station, for example, based on the demand or minimum demand for the QoE indicator of the continuous first service and / or first application and / or first business in the terminal; the first requirement meets the demand for the QoE indicator of the corresponding first service and / or first application and / or first business. The QoE indicator of the target cell meets the first requirement. The service type of the first service includes at least one of the following: Dynamic Adaptive Streaming over HTTP (DASH) based on Hypertext Transfer Protocol (HTTP), Multimedia Telephony Service for IMS (MTSI) based on IP Multimedia Subsystem (IMS), Virtual Reality (VR), MBS, and Extended Reality (XR).

[0112] To facilitate the first base station to obtain information related to the QoE indicator of the first cell of the second base station, in one embodiment, the first information includes at least one of the following:

[0113] a first value of a QoE indicator of a first cell;

[0114] a first identifier, where the first identifier is used to indicate whether the first cell of the second base station can provide a QoE indicator that meets the first requirement;

[0115] an identifier of the first cell;

[0116] an identifier of a third cell, where the third cell represents a first cell that can provide a QoE indicator that meets the first requirement;

[0117] A first value of the QoE indicator of the third cell.

[0118] Here, when the first information is used to indicate the first value of the QoE indicator of the first cell of the second base station, the first information includes at least the first value of the QoE indicator of the first cell and may also include the identifier of the first cell. When the first information is used to indicate whether the first cell of the second base station can provide a QoE indicator that meets the first requirement, the first information includes at least the first identifier and may also include the identifier of a third cell and / or the first value of the QoE indicator of the third cell. When the first information includes the identifier of the third cell and / or the first value of the QoE indicator of the third cell, the first base station can directly determine the target cell in the third cell, thereby improving the efficiency of determining the target cell.

[0119] In one embodiment, the first requirement includes at least one of the following:

[0120] A first value of the QoE indicator of the first cell is the same as the corresponding second value or third value;

[0121] A first value of the QoE indicator of the first cell is better than a corresponding second value or a third value;

[0122] The second value and the third value of the QoE indicator both represent predicted values ​​of the QoE indicator of the first base station.

[0123] Here, QoE indicators can be divided into first-category QoE indicators and second-category QoE indicators. For first-category QoE indicators, the larger the value of the QoE indicator, the better the QoE indicator; for second-category QoE indicators, the smaller the value of the QoE indicator, the better the QoE indicator, such as latency or delay. First-category QoE indicators can include at least one of fluency, clarity, buffering time, and buffer size, while second-category QoE indicators include latency.

[0124] For the first type of QoE indicator, if the first value of the QoE indicator of the first cell is greater than or equal to the corresponding second value or third value, the QoE indicator of the first cell meets the first requirement; if the first value of the QoE indicator of the first cell is less than the corresponding second value or third value, the QoE indicator of the first cell does not meet the first requirement. For the second base station, the second value and / or third value of the QoE indicator can be understood as the target value of the QoE indicator. The third value of the same QoE indicator can be greater than the corresponding second value.

[0125] For the second type of QoE indicator, when the first value of the QoE indicator of the first cell is less than or equal to the corresponding second value or third value, the QoE indicator of the first cell meets the first requirement; when the first value of the QoE indicator of the first cell is greater than the corresponding second value or third value, the QoE indicator of the first cell does not meet the first requirement.

[0126] The second and third values ​​of the same QoE indicator are different and are predicted by the first base station at different times or time periods. For example, the first base station may predict the second and / or third values ​​of the QoE indicator based on the ongoing QoE indicator demand of the first service and / or first application and / or first business in the terminal. Alternatively, the second and third values ​​of the same QoE indicator may represent predicted values ​​of the same QoE indicator at different times or time periods predicted by the first base station.

[0127] In order to maintain a stable QoE of the terminal during movement to ensure a service experience of the terminal, in one embodiment, after receiving the first information sent by the second base station, the method further includes:

[0128] Determining a target cell in the first cell according to the first information; a first value of the QoE indicator of the target cell meets the first requirement;

[0129] Sending the second information or the third information to the terminal; wherein,

[0130] The second information is used to instruct the terminal to switch to the target cell; and the third information is used to instruct the terminal to switch to the target cell preferentially when a CHO triggering condition is met.

[0131] Here, when the first information includes the first value of the QoE indicator of the first cell, the first base station determines, based on the first values ​​of the QoE indicators of the respective first cells, some or all of the first cells that can provide QoE indicators that meet the first requirement, and determines a target cell from among the determined some or all of the first cells. The target cell may be the first cell that can provide the optimal QoE indicator. When the first information includes an identifier of a third cell and / or the first value of the QoE indicator of the third cell, the first base station determines a target cell from among some or all of the third cells. The target cell may be the third cell that can provide the optimal QoE indicator.

[0132] In a traditional switching scenario, the first base station sends second information to the terminal to instruct the terminal to switch to the target cell; in a conditional switching scenario, the first base station sends third information to the terminal to instruct the terminal to switch to the target cell first when the CHO trigger condition is met.

[0133] The first base station can also determine the second base station to which the target cell belongs, and obtain the target base station to which the target cell belongs; at this time, the second information can be used to instruct the terminal to switch to the target cell of the target base station, and the third information can be used to instruct the terminal to give priority to switching to the target cell of the target base station when the triggering condition of CHO is met. The second information may include an identifier of the target cell, and may also include relevant information of the target base station to which the target cell belongs. The third information includes at least an identifier of the target cell, and may also include the triggering condition of CHO and relevant information of the target base station to which the target cell belongs. The relevant information of the target base station to which the target cell belongs may include a set information element (IE, Information Element), and the set IE is used to carry a third identifier. At this time, the third identifier is used to indicate whether the target cell of the target base station can provide a QoE indicator that meets the first requirement.

[0134] In order to improve the matching degree between the first information and the demand, and to improve the efficiency of the second base station in returning the first information, the second base station can feed back the first information based on the fourth information sent by the first base station. Based on this, in one embodiment, before receiving the first information sent by the second base station, the method further includes:

[0135] Sending fourth information to the second base station; wherein the fourth information includes at least one of the following:

[0136] an identifier of the first cell;

[0137] QoE indicators;

[0138] The time or moment when the terminal accesses the first cell;

[0139] A second value of the QoE indicator;

[0140] a first duration, where the first duration represents a duration of the first service and / or the first application and / or the first service after the terminal switches cells, or represents a duration of a second value of a QoE indicator;

[0141] The third value of the QoE indicator;

[0142] The occurrence time of the third value of the QoE indicator;

[0143] a second duration, where the second duration represents a duration of a third value of the QoE indicator;

[0144] a second identifier, where the second identifier is used to indicate the first service and / or the first application and / or the first business;

[0145] a fourth value of the QoE indicator of the first base station, where the fourth value represents an actual value or a measured value;

[0146] first indication information, where the first indication information is used to instruct the second base station whether to feed back a first value of the QoE indicator corresponding to the second identifier;

[0147] second indication information, where the second indication information is used to instruct the second base station to feed back at least one of the first identifier, the identifier of the third cell, and the first value of the QoE indicator of the third cell;

[0148] The first duration is used to instruct the second base station to feed back the first information within the first duration.

[0149] Here, the fourth information includes at least a QoE indicator and / or an identifier of the first cell; optionally, the fourth information may further include at least one of the following:

[0150] The time or moment when the terminal accesses the first cell;

[0151] A second value of the QoE indicator;

[0152] First duration;

[0153] The third value of the QoE indicator;

[0154] The occurrence time of the third value of the QoE indicator;

[0155] Second duration;

[0156] Second identification;

[0157] a fourth value of the QoE indicator of the first base station;

[0158] First instruction information;

[0159] Second instruction information;

[0160] First duration.

[0161] Wherein, when the fourth information includes the second value of the QoE indicator, it may also include at least one of the first duration, the second identifier, the first indication information, the second indication information, and the first duration; when the fourth information includes the third value of the QoE indicator, it may also include at least one of the following: the occurrence time of the third value of the QoE indicator, the second duration, the second identifier, the first indication information, the second indication information, and the first duration. The occurrence time of the third value of the QoE indicator is after the occurrence time of the second value of the QoE indicator. The second value and / or the third value of the same QoE indicator are greater than or equal to the fourth value of the QoE indicator; the second value and the third value of the same QoE indicator at least meet the minimum requirements of the QoE indicator so that the first service and / or the first application and / or the first business in the terminal can continue.

[0162] In actual application, if the first base station needs to limit the duration or time for the second base station to feedback the first information, the fourth information includes the first duration. The second base station needs to feedback the first information to the first base station within the first duration so that the first base station can select the target cell for the terminal in a timely manner, thereby ensuring the handover performance of the terminal. The first base station can discard the first information fed back beyond the first duration and only consider the first information fed back within the first duration. The first duration can include a deadline or deadline, or a specific time period.

[0163] It should be noted that, when the fourth information includes the first indication information, the first value of the QoE indicator of the first cell indicated by the first information can be associated with the second identifier. When the fourth information includes the second indication information, the first information may include at least one of the following: the first identifier, the identifier of the third cell, and the first value of the QoE indicator of the third cell. The second indication information is used to indicate that the second base station can provide a QoE indicator that meets the first requirement for the first service and / or the first application and / or the first service of the terminal, and to feedback at least one of the first identifier, the identifier of the third cell, and the first value of the QoE indicator of the third cell. When the fourth information includes the fourth value of the QoE indicator of the first base station, the fourth information may also include the duration of the fourth value. If the first value of the QoE indicator of the first cell of the second base station is equal to or better than the corresponding fourth value, then it can also be considered that the QoE indicator of the first cell of the second base station meets the first requirement.

[0164] In one embodiment, at least part of the fourth information is predicted by the first setting model.

[0165] Here, the following information included in the fourth information is predicted by the first base station using the first set model:

[0166] an identifier of the first cell;

[0167] The time or moment when the terminal accesses the first cell;

[0168] A second value of the QoE indicator;

[0169] First duration;

[0170] The third value of the QoE indicator;

[0171] The occurrence time of the third value of the QoE indicator;

[0172] Second duration;

[0173] A fourth value of the QoE indicator of the first base station.

[0174] Among them, the first setting model can be an AI model or an ML model, which can be trained using relevant information of the QoE indicator; the first setting model takes the relevant information of the QoE indicator as input and takes at least one of the above items as output. For example, the relevant information of the QoE indicator may include the actual value or historical data of the QoE indicator corresponding to the service and / or business and / or application / application type, the duration of the service and / or business and / or application, etc. It should be noted that the first setting model can be trained by the first base station or by other equipment.

[0175] Correspondingly, the embodiment of the present application further provides a switching method, which is applied to the second base station, and the second base station can be understood as a candidate base station. Figure 3 As shown, the method includes:

[0176] Step 301: Send first information to a first base station.

[0177] The first information is used to indicate a first value of a QoE indicator of a first cell of the second base station, and / or to indicate whether the first cell of the second base station can provide a QoE indicator that meets a first requirement;

[0178] The first cell represents the candidate cell that the first base station predicts the terminal can access; the first requirement represents the requirement of the first continuous service and / or first application and / or first business in the terminal for QoE indicators; the first information is used for the first base station to determine the target cell to which the terminal is to switch.

[0179] Here, the second base station can predict the first value of the QoE indicator of the first cell of the second base station based on historical data or AI model or ML model, or predict whether the first cell of the second base station can provide a QoE indicator that meets the first requirement; generate first information based on the prediction result, and send the first information to the first base station.

[0180] To facilitate the first base station to obtain information related to the QoE indicator of the first cell of the second base station, in one embodiment, the first information includes at least one of the following:

[0181] a first value of a QoE indicator of a first cell;

[0182] a first identifier, where the first identifier is used to indicate whether the first cell of the second base station can provide a QoE indicator that meets the first requirement;

[0183] an identifier of the first cell;

[0184] an identifier of a third cell, where the third cell represents a first cell that can provide a QoE indicator that meets the first requirement;

[0185] A first value of the QoE indicator of the third cell.

[0186] In order to improve the accuracy of the first value of the QoE indicator, in one embodiment, the first value of the QoE indicator of the first cell is predicted by a second setting model.

[0187] Here, the second setting model can be an AI model or an ML model, which can be trained based on the relevant information of the QoE indicator. The second setting model takes the relevant information of the QoE indicator as input and outputs the predicted value of the QoE indicator. It should be noted that the second setting model can be trained by the second base station or by other devices. The first value of the QoE indicator of the first cell can be predicted by the second base station using the second setting model or by other devices using the second setting model.

[0188] In order to improve the matching degree between the first information and the demand, and to improve the efficiency of the second base station in returning the first information, the second base station can feed back the first information based on the fourth information sent by the first base station. Based on this, in one embodiment, before sending the first information to the first base station, the method further includes:

[0189] Receive fourth information sent by the first base station; wherein the fourth information includes at least one of the following:

[0190] an identifier of the first cell;

[0191] QoE indicators;

[0192] The time or moment when the terminal accesses the first cell;

[0193] A second value of the QoE indicator;

[0194] a first duration, where the first duration represents a duration of the first service and / or the first application and / or the first service after the terminal switches cells, or represents a duration of a third value of a QoE indicator;

[0195] The third value of the QoE indicator;

[0196] The occurrence time of the third value of the QoE indicator;

[0197] a second duration, where the second duration represents a duration of a third value of the QoE indicator;

[0198] a second identifier, where the second identifier is used to indicate the first service and / or the first application and / or the first business;

[0199] a fourth value of the QoE indicator of the first base station, where the fourth value represents an actual value or a measured value;

[0202] The first duration is used to instruct the second base station to feed back the first information within the first duration.

[0203] Here, the fourth information includes at least a QoE indicator and / or an identifier of the first cell.

[0204] When the fourth information also includes the time or moment when the terminal accesses the first cell, the second base station predicts a first value of the QoE indicator after the time or moment when the terminal accesses the first cell, or whether the first cell can provide a QoE indicator that meets the first requirement. In other words, the first information corresponds to the time or moment when the terminal accesses the first cell.

[0205] In the case where the fourth information further includes the second value of the QoE indicator, when the first value of the QoE indicator is equal to or better than the corresponding second value, it is characterized that the first value of the QoE indicator meets the first requirement.

[0206] When the fourth information further includes the first duration and the second value of the QoE indicator, when the first value of the QoE indicator within the first duration is equal to or better than the corresponding second value, the first value representing the QoE indicator meets the first requirement.

[0207] In the case where the fourth information further includes a third value of the QoE indicator, when the first value of the QoE indicator is equal to or better than the corresponding third value, it is characterized that the first value of the QoE indicator meets the first requirement.

[0208] When the fourth information further includes the second duration and the third value of the QoE indicator, when the first value of the QoE indicator within the second duration is equal to or better than the corresponding third value, the first value representing the QoE indicator meets the first requirement.

[0209] When the fourth information also includes a fourth value of the QoE indicator and does not include the second and third values ​​of the corresponding QoE indicator, when the first value of the QoE indicator is equal to or better than the corresponding fourth value, the first value characterizing the QoE indicator meets the first requirement.

[0210] In the case where the fourth information also includes the second identifier and the first indication information, the second base station may feed back to the first base station the first value of the QoE indicator corresponding to the second identifier in the first cell, and may also feed back the identifier of the first cell.

[0211] In the case where the fourth information further includes the first indication information and the first duration, the second base station may feed back the first value of the QoE indicator of the first cell within the first duration, and may also feed back the identifier of the first cell.

[0212] When the fourth information also includes the second identifier, the first indication information and the first duration, the second base station can feedback the first value of the QoE indicator corresponding to the second identifier in the first cell within the first duration, and can also feedback the identifier of the first cell.

[0213] In the case where the fourth information also includes second indication information, and includes a second numerical value, a third numerical value, or a fourth numerical value of the QoE indicator, if any first cell under the second base station can provide a QoE indicator that meets the first requirement, then the second base station can feedback at least one of the first identifier, the identifier of the third cell, and the first numerical value of the QoE indicator of the third cell to the first base station; if all first cells under the second base station cannot provide a QoE indicator that meets the first requirement, then the first information fed back by the second base station is used to indicate that all first cells under the second base station cannot provide a QoE indicator that meets the first requirement.

[0214] In the case where the fourth information also includes the first duration, the second indication information, and the second value, the third value, or the fourth value of the QoE indicator, if any first cell under the second base station can provide a QoE indicator that meets the first requirement, then the second base station can feedback the first identifier, the identifier of the third cell, and at least one of the first values ​​of the QoE indicator of the third cell to the first base station within the first duration, or not feedback the first information; if all first cells under the second base station cannot provide the QoE indicator that meets the first requirement, then the first information fed back by the second base station within the first duration is used to indicate that all first cells under the second base station cannot provide the QoE indicator that meets the first requirement.
