A method for supporting session mobility, more particularly, a method for supporting session mobility that can move various sessions between two or more devices by using session initiation protocol (SIP). Various sessions can be simultaneously moved by utilizing a SIP PUBLISH message. Accordingly, a user can utilize various services as they are regardless of changing of service receiving device while the user utilizes various services. Also, the session mobility can be effectively supported whether the target of the session movement is known or not.

Method for supporting session mobility

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.

System for providing context-aware service and method thereof

The present invention relates to a personalized service providing system and a profile information classifying and processing method thereof. The system, linked to a plurality of subscriber stations to provide a personalized service to a subscriber station, classifies and processes profile information for the service. In the profile information classifying and processing method, a) subscriber profile information is generated, b) the subscriber profile information is classified into static profile information and dynamic profile information, and c) the dynamic profile information is selected from the subscriber station to manage the selected dynamic profile information and the static profile information is selected from the system to manage the selected static profile information. The the static and dynamic profile information is classified into public and private profile information to manage the classified static and dynamic profile information.
