    摘要： Disclosed is a method for providing a multimedia Ring Back Tone (RBT) service by using a receiver-side switching center, 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, which comprising the steps of: (a) receiving an ISDN User Part (ISUP) call connection request message including information (multimedia codec information) regarding a multimedia codec from a caller-side switching center when the originating terminal attempts a call connection to a terminating terminal; (b) transmitting the ISUP call connection request message including the multimedia codec information to the sound source-providing server; (c) requesting the caller-side switching center to set the multimedia codec, thereby activating a routing path for the RBT service;' and (d) receiving a RBT sound source selected using the multimedia codec information from the sound source-providing server and transmitting the RBT sound source to the caller-side switching center.

    摘要： Disclosed is a method for terminal codec setup 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 first codec setup message including information (multimedia codec information) regarding a multimedia codec from the called subscriber, after transmitting an ISDN User Part (ISUP) call connection request message including the multimedia codec information to the called subscriber; (b) when the first codec setup message is received, transmitting a second codec setup message for requesting setup of the multimedia codec to a call-side Base Transceiver Station (BTS) , thereby controlling a call-side vocoder located in a call-side Base Station Controller (BSC) to set the multimedia codec; (c) when the first codec setup message is received, transmitting a third codec setup message for requesting setup of the multimedia codec to the originating terminal, thereby controlling the originating terminal to set the multimedia codec; and (d) receiving an RBT sound source selected using the multimedia codec information from the sound source- providing server and transmitting the RBT sound source to the originating terminal.
