Research And Design On Msc Pool Disaster Recovery Technology

With the rapid development of mobile communication technology, mobile softswitch technology is used by more and more operators. The "control and bearer separated" technical architecture makes the mobile communication core network evolve toward system with large capacity and low bureau. As the single node capability of core network equipment has been multiplied, the need of network disaster recovery is more and more urgent. Therefore, how to improve the reliability and robustness of the network for large-capacity equipments has become the focus of attention for operators.In this thesis, the dual homing and MSC Pool technology are analysed and compared first, and advantages and application scenarios of MSC Pool technology is pointed out. Then, from a technical point of view, the key technologies and the basic principles are explored. The strategies, planning principles and the impact on the existing network after the implementation of the MSC Pool are proposed. At last, based on the above resuts, a scheme on MSC Pool networking of Qingdao Unicom mobile core network is put forward.
