Msc Pool Design And Its Implementation

China Mobile has the world's largest core network in circuit domain, the network's main feature is the large, device types. With the 3G business development, has now completed the tandem network and local network IP transformation, introducing softswitch architecture, IP voice-Board/gateway, in addition to the MAP/CAP signalling is still based on TDM signaling network, Nc, Mc, Nb interface is all based on IP, primary realization 2G/TD core network integration.This paper is mainly conducted research on the principle of MSC POOL and Huawei softswitch device implementation. In the core network circuit domain introduce MSC POOL networking technology, not only to achieve network disaster recovery, and real-time dynamic so that traffic in all nodes in the average allocation, comprehensive utilization of network resources, in the current implementation cannot be accelerated scale 2G/TD fusion network, MSC POOL will more BSC/MSC and a POOL, the RNC will physically changing environment becomes logical single Bureau environment, resolve 2G/TD integration in many node scale deployment of the implementation difficulties, the 2G/TD between interoperability becomes this interoperability, promote TD users voice connectivity.On the MSC POOL implementation, I primarily responsible for the implementation of the network design, include:network architecture design; MSC Pool resource planning; signaling network design; speech channel network design; implementation of programme development, as well as the modification of the system performance analysis and system operation and maintenance work.
