A cell handover method and device

Abstract

The invention discloses a cell switching method and device. The method is as follows: respectively obtain the actually measured cell communication quality parameters corresponding to each target cell; respectively obtain the cell of the corresponding target cell according to the actually measured cell communication quality parameters corresponding to each target cell and the preset cell communication quality parameters Performance index: According to the cell performance index of each target cell, the cell performance index of the source cell where the terminal is currently located, and the preset protection threshold value, respectively obtain the handover threshold value corresponding to each target cell; according to the above handover threshold value , acquire the PBGT index corresponding to each target cell, and instruct the terminal to switch to the target cell with the highest PBGT index. By adopting the technical solution of the present invention, in the cell handover process, on the basis of considering the measurement levels of each target cell, the impact of the cell communication quality parameters on the target cell is also considered comprehensively, effectively ensuring the communication of the terminal after switching to the above target cell quality.

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 is jointly performed by MS (Mobile Station; Mobile Station), BTS (Base TransceiverStation; Base Transceiver Station), BSC (Base Station Controller; Base Station Console) and MSC (MobileService Switch Center; Mobile Service Switching Center) Complete, wherein the MS is used...
