Abstract

A method for transmitting a control signal for multimedia service data of UMTS (Universal Mobile Telecommunications System) includes MBMS service data that can be transmitted in a wireless system providing various types of MBMS service. An MBMS scheduling block including an MBMS service identifier list and scheduling information of MBMS RB set information and an MBMS service information block including one MBMS service identifier and MBMS RB set information for a corresponding service are transmitted to a terminal group.

15. A method according to claim 14, further comprising sending a multicast/broadcast service control information to the user equipment through the multicast/broadcast control channel and sending multicast/broadcast service to the user equipment through a dedicated traffic channel.

16. A method according to claim 14, wherein the transition indication includes information on point-to-point traffic channel configuration.

17. A method according to claim 14, wherein the radio access network sends the transition indication to other user equipments through a dedicated control channel.

18. A method according to claim 17, wherein the radio access network sends the transition indication to other user equipments through a dedicated control channel simultaneously with the sending of the transition indication to the user equipment through the multicast/broadcast control channel.

19. A method of receiving by a wireless user equipment a multicast/broadcast service comprising:

receiving a first configuration information through a first channel;

receiving a second configuration information through a second channel after receiving the first configuration information, wherein the first configuration information contains information for receiving the second configuration information; and

receiving the multicast/broadcast service through a third channel after receiving the second configuration information, wherein the second configuration information contains information for receiving the multicast/broadcast service.

20. The method of claim 19, wherein the first channel is a broadcast channel.
