Abstract


As communications technology continues to update the increasingly fierce market competition , the traditional network situation facing increasingly severe , how to protect existing investments on the basis of sustainable development , how to network construction and maintenance cost savings obtained on the basis new business growth point , as major carriers need to solve a problem . Mobile Softswitch Softswitch technology is the introduction of mobile networks , in order to adapt to future softswitch layered architecture as the leading next-generation mobile network construction trends . Mobile Softswitch is through the mobile network bearer and control circuit domain separation , centralized control, decentralized access, hierarchical networking to form a clear idea of ??the core network planning , in line with the direction of network development : the introduction of Voice over IP , using IP end side between the media gateway addressing ability to form a flat network architecture will help simplify network topology : the use of IP bearer mobile softswitch enables flexible networking , reduce network construction costs and operation and maintenance costs , provide rich business and functional and mobile network can achieve smooth evolution to next-generation networks . This paper first introduces the next generation network softswitch and the basic concepts and Softswitch-based Next Generation Network architecture ; introduces the basic NGN networking , interface protocol and backup ; then introduced Anhui Telecom mobile NGN project background , networking , backup and design parameters , and then according to the design parameters given in Anhui Telecom mobile NGN final design. Finally, the future after the arrival in the WCDMA mobile NGN development.
