First Claim
Patent Images
1. A communication method of a hub, the method comprising:
- receiving, from at least one receiving terminal of a receiving virtual group, a data request message including interface information about at least one interface available for use by the at least one receiving terminal;
receiving, from at least one transmitting terminal of a transmitting virtual group and including data corresponding to the data request message, a data transmission message including interface information about at least one interface available for use by the at least one transmitting terminal;
selecting a transmission route from a hub of the transmitting virtual group to the at least one receiving terminal based on the interface information of the at least one receiving terminal and the interface information of the at least one transmitting terminal; and
transmitting the data transmission message via the selected transmission route.

7. A communication method of a receiving terminal of a receiving virtual group, the method comprising:
-
transmitting a data request message including interface information about at least one interface available for use by the receiving terminal to request data of a transmitting terminal of a transmitting virtual group; receiving, from the transmitting virtual group, a data transmission message including interface information about the at least one interface available for use by the transmitting terminal; and updating a mapping table using the interface information of the receiving terminal and the interface information of the transmitting terminal, so that the mapping table indicates that the interface information of the receiving terminal and the interface information of the transmitting terminal are mapped to each other. - View Dependent Claims (8, 9, 10)
