The Evolution On Intelligent Network Of Local Telephone Network Based On NGN Soft-switch

With the development of communications market, fixed-network operators are increasingly facing serious challenges. The inadequate capacity of its network business support and deployment of new services difficult defects have been changed after the Intelligence transformation through the fixed network, It's have taken the initiative part in market competition for its quickly and easily offer new services and applications to meet the consumer demand.In Weihai, China Unicom,Network resource utilization and operational efficiency is relatively low for local networks present quantity, small capacity. Not full mesh connection, part of the client. Unclear network hierarchy and routing complexity between the end offices are making maintenance management more difficult. To optimize the exchange of network structure. Weihai, China Unicom reformed network intelligence based on the first two new local network ZTE soft-witch SS. two sets of relay gateway TG, two sets of signaling gateway SG device, consisting of two ZTE Soft Exchange of SS as a smart tandem to achieve tandem office functions. New sets of ZTE HLR equipment to achieve business attributes for the centralized storage of user's business data user features such as trigger and number portability. Bureau is responsible for all local network clients will follow all the calls (including the Council calls) routed to the soft-witch, HLR inquiries received by the soft-witch calling or called party number information or the intelligent network service access code, and then connecting the end office or trigger Other intelligent network services, to enhance the existing network capacity, flexibility and rapid development of rich, distinctive smart business.After implementation of the intelligent network, the traditional PSTN of the original "network-oriented" type gradually turn into a "user-oriented" type of network. Improve network capacity and access capabilities, enhanced user information management can easily achieve more Multi-agent business.
