Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts 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 different signal coverage cells. At this time, as the mobile terminal moves, the mobile terminal needs to be handed over to a different cell.

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

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 technologies, in particular to a method and device for cell handover. 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 area of ​​each cell is relatively fixed. As the user continues to move, the mobile terminal will be in different cells. When a user enters another cell from one cell, cell switching is required. Generally, the mobile terminal determines the timing of switching from the current cell to the adjacent cell by comparing the Reference Signal Receiving Power (RSRP) value of the cell currently camped on with the RSRP value of the adjacent cell. [0003] However, in the prior art, when performing cell handover, when determining the RSRP value of the adjacent cell, the interference generated by some devices currently working on the mobile terminal to the communi...
