Embodiment Construction

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Generally, when a user is using a mobile terminal, as the location of the user changes continuously, the mobile terminal may be in a different signal coverage cell. At this time, as the mobile terminal moves, the mobile terminal needs to switch to a different cell.

[0024] The embodiment of the present invention provides a cell handover method, which can be applied to a mobile terminal. The method provided in the embodiment of the present invention contr...

Abstract

Embodiments of the invention disclose a cell switching method and a cell switching device. The method comprises the steps of: when the first RSRP value of the first cell currently camped by the mobileterminal is less than a preset threshold, detecting whether the communication frequency band corresponding to the second cell is interfered by the working frequency of the designated device accordingto the communication frequency band corresponding to the second cell and the working frequency of the designated device that is currently in the working state on the mobile terminal, wherein the second cell and the first cell are adjacent cells; determining the current second RSRP value of the second cell according to the detection result; and controlling the mobile terminal to perform cell switching according to the first RSRP value and the second RSRP value. In the embodiments of the invention, the accuracy of the determined second RSRP value is high, thereby reducing mis-switching of the mobile terminal between cells, ensuring the communication quality of the mobile terminal, improving the user experience, and reducing the power consumption of the mobile terminal.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a cell handover method and device. Background technique [0002] In a communication system, the signal coverage area of ​​each base station is generally divided into one or more cells, and the signal coverage of each cell is relatively fixed. As users continue to move, mobile terminals will be in different cells. When a user enters another cell from one cell, a cell handover is required. The mobile terminal generally compares the Reference Signal Receiving Power (RSRP) value of the cell currently camped on with the RSRP value of the neighboring cell to determine the timing of handover from the current cell to the neighboring cell. [0003] However, in the prior art, when cell handover is performed, when determining the RSRP value of the neighboring cell, it does not take into account the interference caused by some devices currently working on the mobile terminal to...
