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.

Claims

1. A method for transmitting information in a wireless communication system between terminals having different communication environments, the method comprising:

sending, by an application server, a request message including a radio environment capability to a second terminal when receiving the corresponding request message for a session setup from a first terminal;

checking, by the second terminal, whether the message sent by the application server includes the radio environment capability; and

sending, by the second terminal, a response message including its own radio environment information to the application server if the message from the application server includes the radio environment capability depending on the checked result.
