With the continuous development of the mobile network

the size of the network continues to expand

the security of the communication system and network capacity is facing enormous challenges.How to improve the utilization of network resources and disaster recovery capabilities

the manufacturers of common concern.MSC pool technology

breaking the traditional network BSC / RNC can only be connected to one MSC limit the number of MSC together to form a Pool of resources to provide services for the connected BSC / RNC.The MSC Pool enhance the core network system resource utilization

reduce signaling overhead

and enhance the efficiency of the system.3GPP standard protocols based on the technical principles of the MSC pool from the start

combined with the current development of the MSC pool

were analyzed on the the MSC pool key technologies and networking principles.
