Analysis And Application Of The Abis Interface Signal Decoding In GSM-R Network

GSM-R system is a kind of specific mobile communication system implemented in railway communication.It is expected to have very high quality and capability.China is going to establish lots of GSM-R networks.In this moment,GSM-R network's communication quality and reliability is of great importance to China's future GSM-R system construction.Abis interface is the communication interface between BSC and BTS.Most of signals from MS to network or from network to MS will go through this interface.Decoding and analyze the Abis interace's signal can do great favour to GSM-R system.This paper's main project is to describe the Abis interface signal decoding and distilling their enclosured information.I hope this paper can provide some experience to other's work in this field.In the paper's first section,the reason of that why to selct this title is gived. The GSM-R system's macro struction and all the interface is introduced.then the main work and the research result is gived.This paper emphasis in the Abis interface signal decoding and the research of how to use it. The Abis interface signal decoding is an effective method to supervise the wireless network and the decoding data is correct,which was demonstrated by the practice engineering, and it's of practice engineering value.
