Voice over internet protocol (VoIP) terminal and information management method thereof
First Claim
1. A Voice-over Internet Protocol (VoIP) terminal comprising:
- a controller adapted to transmit a request message for receiving terminal information to at least one terminal in a multicast group in response to a request for receiving terminal information from a receiving terminal with which the VoIP terminal is attempting to communicate and to communicate with the receiving terminal based on the receiving terminal information received from a certain terminal in the multicast group.

Abstract
A Voice over Internet Protocol (VoIP) terminal and an information management method thereof, in which when any terminal requests receiving terminal information from any receiving terminal in order to communicate with the receiving terminal, a request message for receiving terminal information is transmitted to at least one terminal of a multicast group to which the receiving terminal belongs, and communication is conducted based upon the receiving terminal information received from the terminal of the multicast group. As a result thereof, when the telephone number of the receiving terminal is not known to a user or stored, the user can obtain the telephone number of the receiving terminal without having to inquire of a server or call center that has stored the telephone number of the receiving terminal.

7. A Voice-over Internet Protocol (VoIP) terminal comprising:
-
an information requesting portion adapted to generate a location registration message for VoIP communication, to transmit the location registration message to a server, to join a multicast group identified by a location registration complete message received from the server, and to transmit a request message for receiving terminal information to at least one terminal in the multicast group in response to a request for receiving terminal information from a receiving terminal with which the VoIP terminal is attempting to communicate; and
a communicating portion adapted to communicate with the receiving terminal based on the receiving terminal information received from a certain terminal in the multicast group. - View Dependent Claims (8, 9, 10, 11, 12)

13. A Voice-over Internet Protocol (VoIP) system comprising:
-
a VoIP terminal and a server;
wherein the VoIP terminal is adapted to generate a location registration message for VoIP communication, to transmit the location registration message to the server, to join a multicast group identified by a location registration complete message received from the server, and to transmit a request message for receiving terminal information to at least one terminal in the multicast group in response to the request for receiving terminal information from a receiving terminal with which the VoIP terminal is attempting to communicate, and to communicate with the receiving terminal based on the receiving terminal information received from a certain terminal in the multicast group; and
wherein the server is adapted to register the location of the VoIP terminal based on VoIP terminal information included in the location registration message upon receiving the location registration message, to identify the multicast group of the VoIP terminal based on the VoIP terminal information, and to transmit multicast group information of the VoIP terminal on the location registration complete message to the VoIP terminal.

19. An information management method of a Voice over Internet Protocol (VoIP) system including at least one terminal and a server, the method comprising:
-
transmitting terminal information on a location registration message for VoIP communication to the server from a terminal;
location-registering the terminal based upon the terminal information in the location registration message upon receiving the location registration message, identifying a multicast group of the terminal based upon the terminal information, and transmitting multicast group information of the terminal on a location-registration complete message to the terminal from the server; and
joining the multicast group of the terminal included in the location-registration message received from the server at the terminal, and transmitting a request message for the receiving terminal information to at least one terminal of the multicast group from the terminal in response to a request for receiving terminal information from a receiving terminal with which the terminal is attempting to communicate. - View Dependent Claims (20)
