Method for transmitting/receiving picture caller identification in mobile communication system

PURPOSE: A method for transmitting and receiving picture caller information in a mobile communication system is provided to display caller information using picture data. CONSTITUTION: A voice data channel is set up between an origination-side UE(User Equipment) which generates an origination call and a termination-side UE which receives the origination call(411-429). A data path is generated so that the origination-side UE transmits picture caller information to the termination-side UE(431-441). The origination-side UE transmits picture caller information to the termination-side UE through the data path(449).
