Cell switching method and device

Abstract

The invention discloses a cell switching method and device. The method comprises the following steps: actually-measured cell communication quality parameters corresponding to each target cell are acquired separately; cell performance indexes of each target cell are acquired separately according to the actually-measured cell communication quality parameters and default cell communication quality parameters corresponding to the corresponding target cell; a switching threshold value corresponding to each target cell is acquired separately according to the cell performance indexes of each target cell, the cell performance indexes of a source cell at which a terminal is located at present and a default protection threshold value; and a PBGT index corresponding to each target cell is acquired according to the switching threshold value, and the terminal is indicated to be switched to a target cell having the maximum PBGT index. By adopting the technical scheme of the invention, in the cell switching process, on the basis of considering the measuring level of each target cell, the influences of the cell communication quality parameters on the target cells are considered comprehensively at the same time, so the communication quality of the terminal after the terminal is switched to the target cell can be effectively ensured.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a cell switching method and device. Background technique [0002] In an existing communication system, a wireless network is composed of successive cells. refer to figure 1 It is a schematic diagram of a terminal in the prior art at a cell junction within the coverage of multiple base stations. When the terminal is at the junction of multiple cells, or moves from one cell to another, in order for the terminal to communicate, To obtain continuous services between different cells, it is necessary to perform a cell handover operation on the terminal. [0003] The existing cell switching process consists of MS (Mobile Station; mobile station), BTS (Base Transceiver Station; base transceiver station), BSC (Base Station Controller; base station console) and MSC (Mobile Service Switch Center; mobile service switching center ) together, wherein the MS is used to measu...

Problems solved by technology

[0010] Embodiments of the present invention provide a method and device for cell switching, which are used to solve the problem in the prior art that in the process of cell switching for a terminal, only the level values ​​of all adjacent target cells determine the terminal to which the terminal finally switches. The target cell, which causes the problem of poor communication quality after the terminal completes the cell handover
