ABSTRACT:
A method and apparatus for establishing feedback channels in an MBMS (multimedia broadcast/multicast service) for UMTS (Universal Mobile Telecommunication System) by selectively establishing RRC connections with terminals that are capable of transmitting uplink feedback information regarding the particular MBMS service. When requesting an RRC connection, a terminal sends an RRC connection message including information related to MBMS and the UTRAN selectively establishes an RRC connection with the terminal based on the information related to MBMS. The terminal indicates whether both a point-to-multipoint radio bearer and a point-to-point radio bearer can be received and, optionally, provides terminal class information in the RRC connection request message. The UTRAN gives higher priority to those terminals that indicate the capability to receive both a point-to-multipoint radio bearer and a point-to-point radio bearer when selecting terminals with which to establish an RRC connection, thereby maximizing feedback information regarding a particular MBMS service.
