Method and device for updating an active set cell, terminal and storage medium

Abstract

The invention relates to a method and device for updating an active set cell, a terminal and a storage medium, and the method comprises the steps: receiving an active set updating instruction sent bya base station, the active set updating instruction being used for indicating the deletion of a target cell in the active set cell; measuring the active set cell to obtain a first measurement parameter, and determining a second measurement parameter corresponding to the target cell in the first measurement parameter; determining whether the second measurement parameter meets a preset judgment condition or not according to the first measurement parameter; and when it is determined that the second measurement parameter satisfies the preset judgment condition, reserving the target cell in the active set cell.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, relates to a method, device, terminal and storage medium for updating cells in an active set. Background technique [0002] In a WCDMA (Wideband Code Division Multiple Access, Wideband Code Division Multiple Access) network, in order to ensure that the terminal always stays in a cell with a good signal, various measurement events are usually used to trigger cell update, such as modifying, adding, and deleting active set cells. [0003] For the case of deleting the active set cell, the terminal measures the active set cell to obtain the measured value, and when the measured value is less than or equal to the preset threshold, triggers the 1B event, and sends the measurement report corresponding to the 1B event to the base station, and the base station The report determines to send an update instruction to delete the target cell in the active set of cells to the terminal, and t...

Problems solved by technology

[0004] However, during the above process of deleting the active set cells, the inventors found that there is a certain time delay between the measurement of the active set cells by the terminal and the issuance of the update command by the base station. When updating the target cell, the measurement value that originally triggered the 1B event may be greater than the preset threshold, that is, the signal quality of the target cell becomes better at this time, so if the target cell with better signal quality is deleted, Not only reduces the combined gain, but the active set cells will also cause co-channel interference to other active set cells. For scenarios such as slow channel fading and large cell measurement fluctuations at the edge of the cell, it will degrade the communication service performance and even cause Serious performance problems such as dropped calls
