Method for implementing mobile terminal uninterrupted talking between base stations in cluster system

Abstract

The invention provides a method for realizing an unceasing call of a mobile terminal across base stations in a cluster system, wherein, the realizing process thereof comprises two parts: one is the stage of establishing the call across base stations and the other is the stage of switching base stations by the mobile terminal. The stage for establishing the call across base stations consists of three processes, respectively the cluster controller process, the networking server process and the mobile terminal process. And whether base stations are switched is decided after the mobile terminal is put into the stage of switching base stations by the mobile terminal in the call process, The method can ensure unceasing call of the mobile terminal across the base stations, lower the difficultiesof implementing the system and the mobile terminal, use a control channel to broadcast information of adjacent base stations for switching the mobile terminal across base stations without influencingthe voice quality.

Description

A method for realizing uninterrupted communication between mobile terminals across base stations in trunking system (1) Technical field The invention relates to mobile terminal communication technology, in particular to a method for realizing uninterrupted communication between mobile terminals across base stations in an MPT1327 cluster mobile communication system. (2) Background technology As the MPT1327 digital signaling trunking mobile communication system (hereinafter referred to as the system) has been widely used in our country, the system is not limited to the operation mode of a single base station. After continuous improvement in recent years, the networking function of multi-system and multi-base station based on IP network has been realized now. However, multi-system networking only provides cross-system automatic roaming and calling functions. The mobile terminal cannot realize the function of uninterrupted voice between adjacent base stations similar to the pu...

Problems solved by technology

However, the main disadvantage of the prior art solution is that because of the need to embed the channel-associated inter-phone signaling, the call is interrupted for a short time, which affects the call quality

Because the traffic channel does not define time slots like the control channel, the reliability of signaling transmission is difficult to guarantee, so the same signaling has to be retransmitted multiple times, which will invisibly worsen the existing problems
