It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a method for updating an active set cell according to an embodiment of the present disclosure, as shown in fig. 1, the method includes:
s101, receiving an active set updating instruction sent by a base station.
Wherein the active set update instruction is used to instruct deletion of a target cell in the active set cells.
In this step, the terminal measures the active set cells to obtain initial measurement parameters, and when the initial measurement parameters are less than or equal to a preset threshold, triggers a 1B event and sends a measurement report corresponding to the 1B event to the base station, the base station determines to send an active set update instruction for deleting a target cell in the active set cells to the terminal according to the measurement report, and the terminal receives the active set update instruction.
Wherein, the 1B event indicates that the signal quality of the cell is poor, and the cell with poor signal quality needs to be deleted; the initial measurement parameter may be RSCP (Received Signal Code Power) or Signal-to-noise ratio.
S102, the active set cell is measured to obtain a first measurement parameter, and a second measurement parameter corresponding to the target cell is determined in the first measurement parameter.
Wherein, the first measurement parameter and the second measurement parameter can also be RSCP or signal-to-noise ratio.
In this step, considering that the terminal may have a large fluctuation of a first measurement parameter obtained by measurement due to external environmental factors (such as obstacles or noise interference) during the moving process, which affects the accuracy of the result, in another embodiment of the present disclosure, after obtaining the first measurement parameter, filtering the first measurement parameter, so as to obtain a stable first measurement parameter, improve the accuracy of the measurement result, and determine a second measurement parameter corresponding to the target cell in the filtered first measurement parameter.

In this step, the preset judgment condition may include any one of the following three conditions:
the first condition is that the second measurement parameter is the maximum value of the first measurement parameter.
I.e. it means that the target cell is the cell with the best signal quality among the cells of the active set.
And secondly, the second measurement parameter is larger than the minimum value in the first measurement parameter.
I.e. indicates that the target cell is not the cell with the worst signal quality among the cells of the active set.
And thirdly, the difference value between the second measurement parameter and the maximum value in the first measurement parameter is smaller than or equal to a preset difference threshold value.
I.e. the signal quality of the target cell is not much different from the signal quality of the cell with the best signal quality among the cells of the active set.

In this step, it can be determined that the signal quality of the target cell becomes better through the three conditions in step S103, and the target cell can continue to provide services, at this time, the terminal sends an update failure message to the base station to notify the base station of update failure, and the target cell does not need to be deleted from the active set cell.
In addition, when it is determined that the second measurement parameter does not satisfy the preset determination condition, the target cell in the active set cell is deleted, and an update success message is sent to the base station, at this time, the base station also deletes the target cell in the active set cell that is maintained by the base station.
By adopting the method, after receiving the active set updating instruction which is sent by the base station and used for indicating to delete the target cell in the active set cell, the active set cell is measured again, so that whether the target cell is deleted is determined according to the measurement parameters of the active set cell and the measurement parameters of the target cell, the target cell with good signal quality is prevented from being deleted, the target cell can be continuously served, the call drop rate is reduced, and the quality of communication service is improved.

S203, the base station determines to send an active set updating instruction to the terminal according to the measurement report.
Wherein the active set update instruction is used to instruct deletion of a target cell in the active set cells.
And S204, after receiving the active set updating command, the terminal measures the active set cell again to obtain a first measurement parameter.
S205, the terminal filters the first measurement parameter.
In this step, stable measurement parameters are obtained by filtering the first measurement parameters, so that the accuracy of the measurement result is improved.
S206, the terminal determines a second measurement parameter corresponding to the target cell in the filtered first measurement parameters.
The first measurement parameter and the second measurement parameter may be RSCP or signal-to-noise ratio.
And S207, the terminal determines whether the second measurement parameter meets a preset judgment condition according to the first measurement parameter.
In this step, the preset judgment condition may include any one of the following three conditions:
the first condition is that the second measurement parameter is the maximum value of the first measurement parameter.
I.e. it means that the target cell is the cell with the best signal quality among the cells of the active set.
And secondly, the second measurement parameter is larger than the minimum value in the first measurement parameter.
I.e. indicates that the target cell is not the cell with the worst signal quality among the cells of the active set.
And thirdly, the difference value between the second measurement parameter and the maximum value in the first measurement parameter is smaller than or equal to a preset difference threshold value.
