Design And Implementation Of Desasterv Recovery System For Mobile Local Wireless Access Network

As the increasingly fierce market competition and the increasing users’ needs, network operators pay more attention to the network’s disaster recovery and develop solutions for the network’s disaster recovery from core network to wireless network and from circuit domain to packet domain. By the other hand, as the users are more and more,the network devices are more and more and the wireless base stations are more and more, the work of the network’s disaster recovery is more difficult, and engineers face to even more demanding for doing with the network’s disaster. So it is important to establish a disaster recovery system for mobile local wireless access network to lighten the engineers’ load.This paper analyzes the network architecture of mobile local wireless access network and discusses the theory of disaster recovery for local mobile wireless access network in more detail and summarizes four methods for the disaster recovery. In view of the resource of network, the paper offers a scheme of design and implementation of disaster recovery system. In accordance with the principle of modularization, integration, scalability of system, the designs of the function module, software process and the disaster recover system database were completed mainly, using the Java language and SQL Server 2005 database technology. The testing for main function modules of the system was be done and the results meet users’ expectations.The system can perform the network’s hardware management and generate the software script and load it. This work will promote the development of network’s disaster recovery.
