Research And Implement Of The Base Station Controller In GSM Network Disaster Recovery

Network security is the core of the normal operation of the telecomcompanies is to ensure that the basis of network quality and protectcustomers’ interests. The increasing dependence of the mobile networkfrom the original voice services, data services now, user demand formobile networks allthe time. The base station controller in GSM networkdisaster recovery program of "active prevention, timely detection, rapidresponse, to ensure that the recovery" as the principle, strive to improvethe ability and levelof wireless network disaster recovery protection. Thegoal of the wireless network disaster recovery protection work is toestablish a local wireless network, redundant disaster protection plan,process, organizing wireless network disaster recovery support exercise,improve the emergency handling capacity of major communicationfailure of the wireless network.Base station controller is one of the important node in the GSMnetwork, base station controller to do disaster recovery, you must firstmaster the basic technology, such as: the composition and role of theGSM network system architecture, base station controllers, data backuptechnology, IP bearer network’s reliability. Based on the above basictechnology in existing network applications and practice, and to build thesecurity of GSM mobile network end-to-end disaster recoveryconstruction ideas and China Mobile Communications Corporation GSMnetwork disaster recovery standards and norms ", base station controllersdisaster recovery network. GSM network countries run so far, the base station controller fordisaster recovery, although a unified standard, but each has its unique andcan learn from nature. Disaster recovery program through the network ofrailway communication GSM-R (GSM for Railway) and PakistanMobile’s GSM network disaster recovery program, this paperunderstanding at home and abroad have been able to mature theapplication program, and absorb the essence from which to in the existingnetwork environment, build a new disaster recovery program. Alcatelthree different base station controllers, disaster recovery program, testand compare the existing network in Shanghai, the final selection of acontroller based on Mobile IP bearer network disaster recovery program.Through operations and exercises of the program, confirmed that theprogram is indeed effective and feasible, and create a good social andeconomic benefits.
