Abstract
Disclosed is a method for controlling a terminal for a multimedia Ring Back Tone (RBT) service, which allows RBT sound sources previously set in a sound source-providing server by a called subscriber to be reproduced to an originating terminal by means of a Home Location Register (HLR) and the sound source-providing server for storing the RBT sound sources when a calling subscriber telephones the called subscriber, the HLR storing profile information including whether the subscriber has joined the RBT service. The method includes the steps of: (a) receiving a codec setup message including information (multimedia codec information) regarding a multimedia codec from a switching center; (b) deactivating a decoding function of a voice codec; (c) activating a decoding function of the multimedia codec; (d) receiving the RBT sound sources; and (e) decoding the RBT sound sources through the multimedia codec and reproducing the decoded RBT sound sources.
