The Design And Implementation Of Integerate Service Access Gateway Based On IMS

In the increasingly telecommunications business market competition, the whole business operation is becoming the mainstream trend of the development of global operators. Operators provide rich, flexible business through the integrated network platform. IMS is now considered as the network system structure that can meet the demand of multimedia communication. IMS has become the foundation of organizations to research network integration and business integration.Many operators have upgrade the network to support IMS ability.With the open of network ability, all kinds of third party platform are expanding the business areas, but the expansion of the platform is based on the operators. Network operators and the third party platform connect through the gateway which can help operators open telecommunication network resources and control the use of the resources.For CP/SP, the gateway shields the technology complexity and provides a unified business development environment. The gateway also provides various business abilities.However, as the constantly open of the network ability, especially IMS ability, the existing gateway can’t meet the needs.This paper introduced the integrated service access gateway based on IMS,which is upgraded from the existing gateway. It realizes the Parlay X interface which supports IMS. This gateway upgrades corresponding management module and adds the module to support IMS service capability.Finally, the gateway can support IMS service capability. With this, the gateway opens ParlayX interface to third parties, which realizes the whole business operation. Operators can support more diversified value-added services, the third parties can use more professional service capability, the users can have more substantial business experience.Finally, it can achieve win-win. This paper analyzes the design and implementation scheme of the integrated service access gateway. The main content includes:SOA system, Paraly X gateway, IMS technology and CIN-SCF platform introduction. Then it carries on the demand analysis from the view of system function. The core part of the paper states the overall design and implementation ofthe integrated service access gateway. Then it introduces the test. At the end of the article, the author summarizes the project experience during the period of master and look into the distance of the integrated service access gateway.
