Abstract
In a broadcast/multicast service based on user location information, when a terminal sets contents desired to be received in a specific area, a broadcast/multicast server checks current location information of the terminal transmitted from a location server or from the corresponding terminal, selects contents provided in the corresponding area, and transmits it to the terminal. Thus, a waste of a communication channel can be prevented, and since a user can selectively receive contents or information according to his/her location, user's satisfaction and convenience can be enhanced.
