ABSTRACT:
A context-aware service providing system according to an exemplary embodiment of the present invention includes a plurality of context-aware service providers and a Session Initiation Protocol (SIP) server. The context-aware service provider subscribes an SIP event for user context information based on subscriber information in the context-aware service. The SIP server manages information on the context-aware service provider (i.e., subscription requestor) and the context information obtained from the SIP event subscription request, obtains service terminal capabilities and context information of the user from SIP registration and SIP event publication of the user, and transmits SIP event notification including the context information of the user by selecting a context-aware service provider subscribing the SIP event corresponding to the context information obtained from the SIP registration and the SIP event publication.
