Method and System for Providing Multimedia Ring Back Tone Service by Using Call-Side Switching Center
First Claim
1. A method for providing a multimedia Ring Back Tone (RBT) service by using a caller-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, the method comprising the steps of:
- (a) receiving location information of a terminating terminal, information regarding whether the terminating terminal has joined the RBT service, and information (multimedia codec information) regarding a multimedia codec supported by the originating terminal from the HLR, when the originating terminal attempts a call connection to the terminating terminal;
(b) transmitting an ISDN User Part (ISUP) call connection request message including the multimedia codec information to the sound source-providing server, when the terminating terminal has joined the RBT service;
(c) requesting a caller-side Base Transceiver Station (BTS) and the originating terminal 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 originating terminal.

23. A system for providing a multimedia Ring Back Tone (RBT) service by using a caller-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 when a calling subscriber telephones the called subscriber, the system comprising:
-
a Home Location Register (HLR) for storing profile information including whether the subscriber has joined the RBT service and information (multimedia codec information) regarding a multimedia codec supported by a subscriber terminal;
the caller-side switching center for receiving information regarding whether a terminating terminal has joined the RBT service, and information (multimedia codec information) regarding a multimedia codec supported by the originating terminal from the HLR when the originating terminal attempts a call connection to the terminating terminal, transmitting an ISDN User Part (ISUP) call connection request message including the multimedia codec information to a sound source-providing server when the terminating terminal has joined the RBT service, receiving the RBT sound sources from the sound source-providing server, and transmitting the RBT sound sources to the originating terminal; and
the sound source-providing server for storing the RBT sound sources and transmitting the RBT sound sources selected using the multimedia codec information to the caller-side switching center when the ISUP call connection request message is received from the caller-side switching center. - View Dependent Claims (24, 25, 26)
