SHIP - SIP HTTP INTERACTION PROTOCOL Proposing a Thin-client Architecture for IMS Applications

IMS is capable of providing a wide range of services. As a result, terminal software becomes more and more complex to deliver network intelligence to user applications. Currently mobile terminal software needs to be permanently updated so that the latest network services and functionality can be delivered to the user. In the Internet, browser based user interfaces assure that an interface is made available to the user which offers the latest services in the net immediately. Client software is virtualized using script and widget technologies, which allow user interfaces to run on different hardware platforms and operating systems. Our approach, called SHIP, combines the benefits of the Session Initiation Protocol (SIP) and those of the HTTP protocol to bring the same type of user interfacing to IMS. SIP (IMS) realizes authentication, session management, charging and Quality of Service (QoS), HTTP provides access to Internet services and allows the user interface of an application to run on a mobile terminal while processing and orchestration is done on the server. A SHIP enabled IMS client only needs to handle data transport and session management via SIP, HTTP and RTP and render streaming media, HTML and Javascript.. Furthermore, the SHIP architecture allows new kinds of applications, which combine audio, video and data within a single multimedia session.
