Wireless communication system for performing combined service between terminals having different communication environments
First Claim
1. A method by a Combined Circuit-Switched and Internet protocol Multimedia Subsystem (CSI) Application Server (AS) for supporting a CSI session between an Internet protocol Multimedia Subsystem (IMS) User Equipment (UE) and a CSI UE, the method comprising:
- generating, by the CSI AS, a first message including information about IMS registration status of the IMS UE and information about radio environment capability of the IMS UE,wherein the radio environment capability indicates whether circuit-switched and packet-switched services are simultaneously supported;
sending, by the CSI AS, the first message to the CSI UE in a Circuit-Switched (CS) domain; and
sending, by the CSI AS, a response message to the IMS UE.

Abstract
A method for transmitting information in a wireless communication system and a wireless communication terminal supporting the method, are discussed. In one embodiment, when an application server sends to a receiving terminal a specific message for checking radio environment information or a message including a radio environment capability, the receiving terminal having received the message may send a response message with its own radio environment information to the application server, such that the radio environment information related to the receiving terminal can be sent to the sending terminal after analyzed by the application server.

13. A method by a Combined Circuit-Switched and Internet protocol Multimedia Subsystem (CSI) User Equipment (UE) for communicating over a CSI session between an Internet protocol Multimedia Subsystem (IMS) UE and the CSI UE, the method comprising:
-
receiving, by the CSI UE from a CSI Application Server (AS), a first message in a Circuit-Switched (CS) domain, wherein the first message including information about IMS registration status of the IMS UE and information about radio environment capability of the IMS UE is generated by the CSI AS when the CSI AS receives a request message from the IMS UE, wherein capability information of the IMS UE is added to the first message by the CSI AS, and wherein the radio environment capability indicates whether circuit-switched and packet-switched services are simultaneously supported; and sending, by the CSI UE to the CSI AS, a second message including capability information of the CSI UE in response to the first message. - View Dependent Claims (14)

15. A Combined Circuit-Switched and Internet protocol Multimedia Subsystem (CSI) Application Server (AS) for supporting a CSI session between an Internet protocol Multimedia Subsystem (IMS) User Equipment (UE) and a CSI UE, the CSI AS comprising:
-
a transceiver; and a processor configured to; generate a first message including information about IMS registration status of the IMS UE and information about radio environment capability of the IMS UE, wherein the radio environment capability indicates whether circuit-switched and packet-switched services are simultaneously supported, control the transceiver to send the first message to the CSI UE in a Circuit-Switched (CS) domain, and control the transceiver to send a response message to the IMS UE. - View Dependent Claims (16)
