Design And Achieve Of The Softswitch Network For Liaoning Unicom

The function of The Switch Network is self-evident and The Switch Network's installing and maintenance are very important in the whole mobile communication network, along with the development of the mobile communication network, the development of 3G is more and more evident. But the current Switch Network of Liaoning Unicom is not satisfying because of the growing of Unicom's operation, and the workload of maintenance is changed to very heavy because of the facility's aging. Although the Unicom increase the maintenance engineer continually, but system often happen accident, so the feasibility is very low to switch to 3G smoothly. The Softswitch is as the core in the next generation Packet Switch Network, its function is that itself's load and control is detached, this function of Softswitch make the centralized maintenance to be possible, and the Softswitch is base on R4 protocol of WCDMA, so the system can translate to 3G smoothly base on the current network. The Liaoning Unicom present network uses the MSC is Lucent 5ESS,Because Lucent's Corporation's 5ESS already suspended production, Causes the Liaoning Unicom to be very many the new service to be unable to realize or the realization cycle is very long. In order to adapt the correspondence profession competition day by day intense situation,The Liaoning Uincom must replace the existing MSC, Exchanges above merit to cause Softswitch to exchange into the replace Softswitch the first choiceThe pivotal technology of Softswitch is the itself's load and control is detached. This treatise detailedly introduce a method of the load and control's abruption and the Mc interface's design and realization through M2UA link. In order to assure system's safety and stabilization, the author use a solution of the double location, to validate these two methods is feasible and get a good society benefit via system running.
