Design and development of Middleware Gateway IP Multimedia System and Web Services

Rapid growth in Internet (Web) applications and usage of mobile in telecommunication is present trends in communication. In Web 2.0 web services architecture is become versatile tool for enterprise solutions in distributed environment systems. To provide an enterprise solution it is not possible to get professional solution at one place. Hence we need to integrate different web services to provide an enterprise solution to meet the requirements. To integrate different web services Service Oriented Architecture is developed which uses SOAP Protocol.Web services provide a standard means of interoperating between different software applications, running on a variety of platforms and/or frameworks .A Web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machineprocessable format (specifically WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards. In mobile multimedia applications are used to transfer audio and video information using internet. To access internet on mobile signaling protocols are developed. Among those protocol stack session initiation protocol (SIP) is commonly used. To combine modern web features (Web Services) on to mobile phone interoperability problem is occurred, because mobile uses SIP messages and web services uses SOAP (Simple Object Access Protocol) messages to perform communication. It means a web service does not understand SIP messages and vice-versa. In this regard a necessity is identified to develop application level gateway to exchange the SIP/SOAP message interface.
