The electronic device can be a terminal device. Optionally, the terminal device includes but is not limited to a mobile phone, a computer, a smart voice interaction device, and the like. The cell handover method of the embodiments of the present disclosure can be executed by the cell handover apparatus of the embodiments of the present disclosure, and the cell handover apparatus of the embodiments of the present disclosure can be configured in any electronic device to execute the cell handover method of the embodiments of the present disclosure.

[0028] In some implementations, the prediction model can be pre-trained based on sample training data by a cloud server to obtain a target prediction model, and the target prediction model can be deployed to a terminal device, wherein the sample training data can include a trigger threshold value of a sample conditional handover (CHO) cell, wireless performance, movement information, location information, and cell information of a sample terminal device.

[0029] Optionally, the prediction model can also be deployed to the terminal device, and the target prediction model can be obtained by pre-training the prediction model based on sample training data by the terminal device.

[0030] Further, the terminal device receives CHO configuration information configured by a network device, wherein the CHO configuration information includes an identifier of a plurality of candidate CHO cells, a network configuration trigger threshold value of the candidate CHO cells, and the like. Further, the associated information of the terminal device is obtained, wherein the associated information includes but is not limited to wireless performance, movement information, location information, and cell information, and the CHO configuration information configured by the network device and the associated information of the terminal device are input into the target prediction model, and the target prediction model outputs a predicted trigger threshold value of one or more candidate CHO cells of the terminal device.

[0032] S102, a first message of a candidate CHO cell is obtained.

[0033] In some implementations, the terminal device can measure the signal of the candidate CHO cell to obtain the first message of the candidate CHO cell. The first message can be signal quality information of the candidate CHO cell, such as signal strength, signal stability, and the like.

[0034] Optionally, the first message of the candidate CHO cell can be obtained by obtaining a synchronization block signal of the candidate CHO cell and performing signal quality measurement on the synchronization block signal.

[0035] It should be noted that the order of the positions of steps S101 and S102 is not limited. The first message of the candidate CHO cell can be obtained before step S101 or after step S101. The order of the positions of steps S101 and S102 in the embodiment can be adjusted as needed. For example, the first message of the candidate CHO cell can be obtained first, and then the prediction trigger threshold value is obtained. Alternatively, the prediction trigger threshold value can be obtained first, and then the first message is obtained. The present disclosure does not make specific limitations.

[0036] S103, determining a target CHO cell from the candidate CHO cells according to the first message of the candidate CHO cell and the prediction trigger threshold value.

[0037] In some implementations, it can be determined whether the candidate CHO cell satisfies the handover condition based on the first message of the candidate CHO cell and the prediction trigger threshold value, and the candidate CHO cell that satisfies the handover condition is taken as the target CHO cell.

[0049] It can be understood that when the terminal device starts the function of obtaining the predicted triggering threshold value of the candidate CHO cell based on the target prediction model, the terminal device can receive the predicted triggering threshold value output by the target prediction model. When the terminal device does not start the above function, the terminal device can directly obtain the configuration triggering threshold value according to the CHO configuration information sent by the network device. That is, it can be determined in advance whether the terminal device starts the target prediction model.

[0054] In some implementations, there can be one or more candidate CHO cells satisfying the cell switching condition. If there is one candidate CHO cell satisfying the cell switching condition, the candidate CHO cell is taken as the target CHO cell.

[0055] Optionally, if there are multiple candidate CHO cells satisfying the cell switching condition, one CHO cell can be randomly selected from the candidate CHO cells satisfying the cell switching condition as the target CHO cell. Or, the CHO cell with the best signal quality can be selected from the candidate CHO cells satisfying the cell switching condition as the target CHO cell.

If the terminal device starts the target prediction model, the prediction trigger threshold value of the candidate CHO cell can be determined based on the target prediction model, and the target CHO cell can be determined from the candidate CHO cell according to the first message of the candidate CHO cell, and the terminal device is switched from the camping cell to the target CHO cell. According to the target prediction model, the prediction trigger threshold value can be determined according to the associated information of the terminal device itself to give an updated accurate prediction trigger threshold value. At the same time, the differences of different terminal devices are compatible, so that various types of terminal devices can obtain more accurate prediction trigger threshold values, which helps the smoothness of the terminal device switching cells, guarantees the stable network connection, and further improves the user experience.
