<p>A method for forwarding information in a wireless communication system and a wireless communication terminal supporting the same are provided to increase the satisfaction index of multimedia communication and support efficient communication by delivering the wireless environment information of a CSI(Combination of CS and IMS services) UE(User Equipment) to an IMS UE and providing information about a service which can be added between the two UEs. An IMS UE transmits an INVITE message and makes a request to establish a session to connect a SIP-based voice service with a CSI UE(S40). The second S-CSCF of an IMS core, to which the IMS UE belongs, forwards the INVITE message to the first S-CSCF of an IMS core, to which the CSI UE belongs, according to IMS session setup procedures(S41). The first S-CSCF, receiving the INVITE message, executes a service logic, authenticates the CSI UE, and forwards the INVITE message to a CSI AS(Application Server), based on routing information read from an HSS(S42,S43). The CSI AS confirms which media type the INVITE message contains. In case that the INVITE message contains a voice component and a non-voice multimedia component, the CSI AS executes session splitting and transmits the voice component and the non-voice multimedia component respectively to the CS domain of the CSI UE and the IMS domain of the IMS UE.</p> |
