METHOD AND APPARATUS FOR PROVIDING NON-SUBSCRIPTION BASED SERVICE IN THE IMS NETWORK REGARDING THE CAPABILITIES OF THE MOBILE TERMINAL

摘要

A method and an apparatus for providing a non-subscription based service according to performance of UE(User Equipment) in an IMS(Internet Multimedia Subsystem) are provided to supply the non-subscription based service needing no special user profile in the IMS, supply services according to performance of the UE, and more efficiently and elastically using an iFC(initial Filter Criteria) by using the iFC included to the user profile of the UE. When registering UE(User Equipment) in an IMS(Internet Multimedia Subsystem) domain, performance information of the UE is received from the UE. A service profile(301) including at least one iFC(initial Filter Criteria)(303) for designating an application service for processing services for the UE is obtained and stored. A temporal iFC(304) for designating an application server of a non-subscription based service is generated according to the performance information and added to the service profile. When a call signal(310) related to the UE is received, the call signal is processed by applying at least one iFC and temporal iFC of the service profile.
