Fig. 1 is a schematic application scenario diagram of a cell handover method according to an embodiment of the present application. Examples are given in connection with the illustrated scenario: when the base station receives a cell switching request of the user terminal, the user sensing rate of the user terminal in the target cell is obtained based on the user sensing rate corresponding to different signal quality under each cell which is established in advance according to the signal quality of the user terminal in the target cell.

If the user perception rate of the user terminal in the target cell is smaller than the user perception rate of the user terminal in the current cell, the switching to the target cell is indicated that the user perception rate cannot be improved, and even the user perception rate is reduced, the cell switching is not executed.
In the related art, cell switching is based on signal quality only, and the signal quality cannot fully reflect the user perception level, so that the cell switching cannot obtain an ideal state.
The following examples are presented to illustrate aspects of embodiments of the application.
Example 1
Fig. 2 is a flow chart of a cell handover method according to a first embodiment of the present application, the method includes the following steps:

s102, obtaining a user perception rate of the user terminal in a target cell based on the user perception rate corresponding to different signal quality under each cell established in advance according to the signal quality of the user terminal in the target cell;
s103, if the user perception rate of the user terminal in the target cell is not less than the user perception rate of the user terminal in the current cell, switching the user terminal to the target cell; and if the user perception rate of the user terminal in the target cell is smaller than the user perception rate of the user terminal in the current cell, not executing the switching.
As an example, the execution subject of this embodiment may be a cell switching apparatus, and there are various implementations of the cell switching apparatus. For example, the program may be software, or a medium storing a related computer program, such as a usb disk; alternatively, the apparatus may be a physical device, such as a chip, a smart terminal, a computer, a server, etc., in which the relevant computer program is integrated or installed. In practical application, the cell switching device can be set independently or integrated in the base station.
In one example, the handover request is sent after the user terminal monitors that the signal quality of the current cell and the signal quality of the neighboring cell meet the cell handover condition.
In connection with the scene example: the user terminal judges whether to send a switching request according to the signal quality of the user terminal in the current cell and the signal quality of the user terminal in the adjacent cell; for example, the cell handover condition may be set to determine that a handover request needs to be issued when the signal quality of the ue in the neighboring cell is better than the signal quality of the ue in the current cell. And if the judgment is made that the switching request is sent, the adjacent cell is the target cell. For example, if the signal quality of the ue in the current cell is smaller than that of the neighboring cell and the phase difference value exceeds the preset first threshold, it is indicated that the signal quality of the neighboring cell is significantly higher than that of the current cell, and the neighboring cell is used as the handover target cell and a handover request is sent to the base station.

For example, assuming that the predetermined error range is 3dB, a signal quality within ±3dB of the signal quality of the target cell with the user terminal is selected as the first signal quality. And obtaining first user perception rates corresponding to the first signal quality respectively based on the user perception rates corresponding to different signal qualities in each cell. And calculating the average value of all the first user perception rates as the predicted user perception rate of the user terminal in the target cell.
Based on the above embodiment, the user perception rate is used as the cell switching basis in a manner of corresponding the signal quality to the user perception rate, so that the perception level of the user can be directly reflected. The predicted user perception rate of the user terminal in the target cell is obtained by calculating the average value, so that the error influence can be reduced.

And respectively establishing user perception rates corresponding to different signal qualities for each cell. And acquiring the signal quality of all users in the current cell and the corresponding user perception rate in the current cell. If the quality of the plurality of user signals is the same, calculating the average value of the user perception rates corresponding to the user signal quality as the user perception rate corresponding to the signal quality. For example, for cell 1, cell 2, cell 3, etc., each cell has user a, user B, user C, etc., and user a, user B, and user C of cell 1 have respective signal qualities and corresponding user perceived rates. If the signal quality of the user A and the signal quality of the user B in the cell 1 are the same, calculating the average value of the user perception rates of the user A and the user B as the user perception rate corresponding to the signal quality.
Based on the above embodiment, by acquiring the signal quality and the user perception rate of the user in the cell, a corresponding relationship between the signal quality and the user perception rate is established, and a basis is provided for calculating the user perception rate of the user terminal in the target cell.
In one example, the user perceived rate includes a user perceived uplink rate and a user perceived downlink rate, and the cell switching method further includes: acquiring uplink flow and downlink flow of a user terminal in a certain time under a current cell; the obtaining the user perception rate of the user terminal in the target cell based on the user perception rate corresponding to different signal quality under each cell established in advance according to the signal quality of the user terminal in the target cell comprises the following steps: if the uplink flow is smaller than the downlink flow, obtaining a user perception rate of the user terminal in a target cell based on user perception downlink rates corresponding to different signal qualities in the target cell according to the signal quality of the user terminal in the target cell; if the uplink flow is greater than the downlink flow, the user sensing rate of the user terminal in the target cell is obtained based on the user sensing uplink rate corresponding to different signal qualities in the target cell according to the signal quality of the user terminal in the target cell.
In combination with the scenario example, the user perceived rate includes a user perceived uplink rate and a user perceived downlink rate, which respectively reflect uplink traffic and downlink traffic, and traffic emphasis directions of different users are different, and when switching cells, main use traffic of the users should be considered. And respectively establishing corresponding relations between the user perceived uplink rate and the user perceived downlink rate when establishing the user perceived rates corresponding to different signal qualities. If the downlink traffic of the user is redundant with the uplink traffic in a certain time, the user is mainly using the uplink traffic, and the user sensing uplink rate should be calculated when the user sensing rate is calculated, so as to correctly guide whether the cell switching is performed.
Based on the above embodiment, by distinguishing the uplink rate and the downlink rate to perform the user perception rate calculation, the user perception rate calculation can be provided for the users with different service emphasis, and the prediction result is more accurate.
In one example, the signal quality includes a reference signal received power or a reference signal received quality.
For example, in combination with the scenario, the reference signal received power reflects the coverage strength of the signal, and the reference signal received quality reflects the signal-to-noise ratio and the interference level of the signal. In practical application, the corresponding signal quality is selected as the basis of cell switching according to a specific application scene.
