Method for solving terminal repeating switch

Abstract

The invention discloses a method by setting timer on local network side to solve terminal repeating switch, which comprises: A. terminal sends switch requirement to local network; B. network side starts timer for timing, and decides whether there is another switch requirement when timing ends; if yes, turns to step C; or else, continues the calling without switch; C. network side switches the terminal to continue calling on switched zone. This invention can avoid frequent switch when calling signal drifts or encounters conflict from other signal, and decreases local network resource.

Description

technical field [0001] The invention relates to terminal switching technology in wireless local network, in particular to a method for solving terminal repeated switching. Background technique [0002] At present, there are many wireless local network operators, which have the right to operate wireless local networks, but cannot operate mobile networks. In places with relatively strict regulations, the roaming area of ​​terminals is required not to exceed the area under the jurisdiction of the wireless local network operator. The range of the base station or the range of multiple base stations, beyond the range, the call service cannot be provided to the terminal. This situation is called roaming restriction of the terminal. [0003] Currently, there are many methods to realize roaming restriction judgment of a terminal based on a cell, a single base station or multiple base stations. [0004] figure 1 It is one of the flow charts of the prior art to realize the determina...

Problems solved by technology

However, the environment of the terminal changes very quickly during the mobile process, especially when the terminal is in the overlapping area of ​​two base stations, such as base station A and base station B, it is very likely that the current terminal is in the coverage area of ​​base station A, with the signal Occasionally drifting to base station B or being interfered by the call signal of base station B, the terminal will switch from base station A to base station B, and then switch back to base station A as the call signal of base station A recovers. Such repeated switching must be accompanied by the terminal Roaming restriction judgment, so that the roaming restriction judgment process of the terminal is executed multiple times in the area covered by base station A and base station B respectively in a short period of time, which is very difficult and performing multiple roaming restriction judgments on the terminal wastes the wireless local network
