The present invention relates to a system and method for providing personalized service.

Due to the rapid increase in the number of Internet users, various popular services using the Internet have been created due to the popularization of Internet services. Session initiation protocol (SIP), which is widely used in multimedia session control and Internet telephony service, is an application layer control protocol for controlling the establishment, modification, and termination of sessions for multimedia communication.

In addition to services provided by existing telephone networks using SIP, conferencing services (multimedia conferences, multipoint conferences), mobility support services (terminal mobility, user mobility, service mobility), instant messaging services, user preference preference services, and Internet information appliances control services can be provided.

With this SIP-related technology, IEEE Communications Magazine has published a SIP-based system for ubiquitous computing in home networks. For ubiquitous computing in a home network, this allows a user to search for a service device resource in an arbitrary region by using location information of the user and to provide a service by utilizing the capabilities of devices existing in the corresponding region. According to this technology, although there is an effect that the user can utilize the resources existing in the area when moving, the call control itself is performed by the terminal, so it is necessary to have its own terminal capable of SIP service in the corresponding area. Can be used to perform services.

On the other hand, as the technology using SIP has shifted its focus from Internet telephony service to user-oriented service, technologies such as reflecting user preferences, preempting resources for emergency calls, and information filtering have been actively discussed.

In order to provide a service according to a user's preference in a conventional SIP-based service, each user terminal manages user preference information, and by using this, each user terminal intentionally needs to perform SIP location registration. The terminal is selected based on the user's preference among the location information. However, if a user does not exist near the terminal selected when providing a service, a call connection is not established and an unnecessary message flow occurs.

An object of the present invention is to provide a personalized service providing system and method for performing a service to an optimal terminal having a high priority according to user preference among a plurality of service terminals existing around a mobile user.
