Abstract
The IP Multimedia Subsystem (IMS) is considered as a valid possibility to tackle the seamless provision of multimedia services in both packet switched and circuit switched networks. The Session Initiation Protocol (SIP) is applied as a protocol for signaling, but is not yet used to fully exploit the potential of dynamic and context-aware service provision. In this paper we present a method to semantically enhance SIP. Tailored to this method, a novel kind of proxy is introduced to enable the automatic interpretation of user requests in a context-aware manner. The decoupling of service request and response in terms of semantic addressing facilitates the immediate publication of new services in IMS and eases the creation of user requests.
