Patent Images
1. A method of generating a ring back tone in a first terminal communicating based on an internet protocol, the method comprising:
- identifying type of a network to which a second terminal requesting a call setup belongs;
generating ring back tone data to be transmitted to the second terminal according to the type of the network;
inserting the ring back tone data into a response message to the call setup; and
transmitting the inserted response message to the second terminal.

17. A method for generating a ring back tone for terminals which are operated based on different communication protocols, comprising:
-
receiving a call setup message from an access point of a first network connected to a first terminal;
inserting ring back tone data into a response message to the call setup message; and
transmitting the inserted response message to the access point;
wherein the ring back tone is reproduced from the response message at the access point. - View Dependent Claims (18, 19)

20. A system for generating a ring back tone for terminals which are operated based on different communication protocols, comprising:
-
a first terminal in a first network;
a second terminal in a second network, the second terminal generating ring back tone data in response to a request of call setup from the first terminal and inserting the ring back tone data into a response message based on real time transport protocol; and
a connecting mechanism for transmitting a call setup message to the second terminal and re-producing a ring back tone from the response message, wherein the first terminal belongs to a public switched telephone network and the second terminal belongs to an Internet protocol network.
