    摘要： Disclosed is a method and a system for providing a terminal-based ringback tone substitute service, as well as a mobile communication terminal for the same. The method includes the steps of (a) receiving a request for an originating call for voice communication with a called terminal from a calling terminal; (b) transmitting a ringback tone start message to the calling terminal, the ringback tone start message being a control message informative of beginning of a ringback tone section; (c) paging the called terminal; (d) transmitting a ringback tone termination message to the calling terminal, the ringback tone termination message being a control message informative of ending of the ringback tone section, and connecting the voice communication between the calling terminal and the called terminal when a response to paging is received from the called terminal; and (e) transmitting the ringback tone termination message to the calling terminal and transmitting unanswered messages to the calling terminal when no response to the paging is received from the called terminal. The mobile communication terminal can play a high-quality ringback tone substitute without being affected by the voice channel environment.

    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.
