The Research On The Services Interworking Of Different Carriers Based On NGN

Next-generation network using IP technology to carry voice, data, multimedia and so on multi-type service, realizes the Internet, Telecom Network, the broadcast television network three kind of network fusions. In the next generation network, each AAA not only need improve the network performance to improve the network transmission quality, provides the type rich service, so that users can easily enjoy the network of other special services provided by other carrier. At present, Interconnection and Interworking existence communication protocol between carrier's causes not identically the service exchanges, between the net to settle accounts causes the human for not to pass, the supervision system not perfectly is unreasonable with difficulty the speculator has an opportunity, "unites does not pass", "passes, but impeded" the event has not seen withering away. if not timely, scientific solution to the problem of service interworking between carriers, users will only be in the range of the operator's network provided the use of their services, Interconnection and Interworking between operators is not only the next-generation networks can No healthy, sustainable and stable development, is able to lead the next generation network to the information society worldwide, bridging the digital divide on major issues.This paper was around the characteristics of the next generation of network integration。First, the explanation to the Interconnection and Interworking's concept, The key technology of Internet POI and the Gateway of Interconnection is introduced, Unifies overseas realizes the way to give in our country next generation network chooses the establishment POI and the Gateway of Interconnection the plan. Profits from the China UnionPay to achieve cross CUP service interworking model, Analysis next generation network service characteristic, Proposed also establishes in our country specially is responsible for between the carrier the service Interworking third party organization is the China Union Service, the China Union Service formulates Inter-Carrier the communication protocol, to unify between the Inter-Carrier the making-up prices, establishes the perfect supervision system and shoulders the supervision responsibility. China Union Service key is to build Business Exchange Network, is responsible for the Inter-Carrier service forwarding business, traffic statistics and the cost of clearing,, the effective realization of Inter-Carrier services interworking. In this paper gives take Net joint center as the core Union Service Business Exchange Network structure drawing. Introduced the same service different Inter-Carrier services interworking and the different service different Inter-Carrier services interworking network structures and business processes and settlement system of operation flow. Finally the simulation of the proposed Union Service Business Exchange Network performance analysis and verification of the Union Service Business Exchange Network operations technical feasibility and the effectiveness of exchange.
