The Inplement And Application Of MSC IN POOL Dynamic Redundancy System

With the development of communication market and communication network scalecontinues to expand, the traditional TDM exchange has been unable to meet the developmentof network services, soft switching high capacity bureau is an inevitable trend. Large capacitycore network equipment is in improving the network processing rate of equipment utilizationability of supporting resource, at the same time, also to the safe operation of the network hasbrought more serious risk. once the large capacity equipment break down,it will make thehundreds of thousands or even millions of users covered by the network unable user thenetwork. Therefore, the stable operation of the core network equipment is necessary to ensurethat the safe network. therefore, all kinds of emergency measure of core network is growing.This article will study the current softswitch core network equipment of msc in pooldynamic disaster backup plan and the actual application.Namely,the msc gathered together,realizing the resource sharing of each msc, complement each other, to greater than a singlemsc service area of the function of the centralized control. It can achieve the same servicearea within the pool of msc server shared capacity, traffic equilibrium, make full use ofnetwork resources, and more important is the function of redundant protection mechanismcan realize network level, namely when the user’s msc stop service,it can be made the othermsc in the same pool take over all the business users, after the failure of minimizing the userside of the fault.The paper based on the sg mobile network of msc in reforming as the research objectof the pool. The paper compares the pros and cons of the core network of shaoguan mobiledisaster in recent years,and puts forward the existing disadvantages of current means ofdisaster.It compared and analyzed the present situation at home and abroad, put forward thecore of the innovation network emergency technology: core network equipment disaster intothe pool. The biggest bright difference of SG mobile msc pool and traditional pool scheme isthat, after a fault,the pool disaster recovery can be realized, the user can immediately resumecalled business instead of waiting for a user to restore the periodic location update of thecalled function. In calling service recovery, it can realize the first service call success,minimizing the user perception of business failures. Through the implementation of the poolreform and the operation of the business, the validation of disaster effect after the innovation,proved the validity of the scheme.
