WIRELESS BASE STATION, METHOD OF SELECTING WIRELESS BASE STATION, METHOD OF MULTICASTING, AND WIRELESS TERMINAL

摘要

The invention provides a wireless base station for providing a multicasting service that transmits the same information to a plurality of wireless terminals simultaneously. A wireless base station is connected with a plurality of wireless terminals and provides a multicasting service for a plurality of wireless terminals. The wireless base station determines autonomously whether to multicast. The invention also provides a method in which a wireless terminal selects a wireless base station that multicasts. When a wireless terminal can receive the same multicast information from a plurality of wireless base stations, the wireless terminal selects fewer wireless base stations that provide the same information.
