A processing method and device for preventing ping-pong switching

Abstract

The embodiment of the invention discloses a processing method and device for preventing ping-pong handover, and the method comprises the steps: obtaining the current cell state information after receiving a handover completion message sent by a terminal, and obtaining the current first position information of the terminal if judging that the cell state information meets a preset condition; After ameasurement report sent by the terminal is received, if it is judged that the switching cell is in the penalty list of the target cell, current second position information of the terminal is obtained; Further determining the moving distance of the terminal; And if it is judged that the moving distance is within the preset range, not allowing the terminal to be switched to the switching cell so asto prevent ping-pong switching. The position information of the terminal when switching is completed and the terminal is to be switched to other cells is acquired, the moving distance of the terminalis calculated, when the moving distance is within the preset range, the terminal is not allowed to be switched to other cells, the judgment process is simple, different test scenes can be effectivelydistinguished, ping-pong switching is inhibited, and misjudgment conditions are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a processing method and device for preventing ping-pong switching. Background technique [0002] An LTE (Long Term Evolution, long term evolution) network base station and a terminal (UE) communicate with each other through an air interface Uu interface. The channel environment of the Uu interface is complicated. Sometimes there will be a situation where the signals of several cells are interleaved, and a handover from A cell to B cell may occur, and then from B cell to A cell, that is, a ping-pong handover occurs. [0003] The existing UE ping-pong handover decision trigger adopts an event trigger mechanism, and after the target cell receives a handover request message carrying UE history information from the source cell, the record is stored. When the target cell receives the RRC (Radio Resource Control) reconfiguration completion message fro...

Problems solved by technology

For example, the two cells A and B have the same coverage or part of the same coverage. When the number of users in A cell is large, the users will migrate to B cell, but when they switch to B cell, they may migrate to A cell due to coverage reasons. This ping-pong switching situation may reciprocate

[0005] In the process of realizing the embodiment of the present invention, the inventor found that the existing method is too complicated to judge the suppression of ping-pong switching, and it is prone to misjudgment
