The Design And Implementation Of Soft-Switch Tandem Network Expansion For Henan Mobile

With the rapid expansion of mobile network scale and the gradual progress of the mobile technology, the number of mobile users in China has increased dramatically. Simultaneously, the competition in the telecom market has become more and more intensive. The existing Mobile telecom technology based on TDM can't satisfy the needs of technological development and can't meet the new market requirements. Therefore, the new telecom technology represented by Soft-Switch is gradually becoming the Mobile telecom operator's target.Based on the analysis of the background of Soft-Switch network and the operating experience of Henan Mobile communication soft-switch tandem network, this thesis introduces a detailed design scheme and the implementation of the improved network capacity to meet long distance call requirement. With the implementation of project,we have the testing of the hardware,operation and maintenance,serving and the important of capability,which including statistical of call and voice tone testing and the consummate capacity of tandem network. According to Heman mobile communications network development plan it is necessary that IP technology could be used to all network. At the same time , the tandem systems should also be changed to the network using IP to meet Henan mobile communication's network requirement. It will establish a solid foundation for the development of the future network.Currently, the system is running stably and reliably in Henan Mobile communication, which brings both profit and social benefit to Henan Mobile communication.
