Abstract

A communication system providing a multimedia broadcast/multicast service (MBMS). Control message to be transmitted to user equipments (UEs) desiring to receive the MBMS service, paging message including information indicating an operation of transmitting a response to the paging message received, is transmitted to the UEs, and thereafter, the control information corresponding to the paging information is transmitted, thereby minimizing interference and use of uplink resource.

Claims

1. A method for transmitting control information for a multimedia broadcast/multicast service (MBMS) by a radio network controller (RNC) in a mobile communication system including a user equipment (UE) and the RNC for providing the MBMS to the UE, the method comprising the steps of:

if a control message for the MBMS to be transmitted to the UE is generated, generating operation instruction information for the UE instructing whether to respond to a paging message; and

transmitting the paging message including the operation instruction information to the UE before transmission of the control message.

2. The method of claim 1, wherein the operation instruction information includes state transition instruction information representing whether to respond to the paging message for the UE.

3. The method of claim 1, wherein the operation instruction information includes a generation cause of the paging message.

4. The method of claim 1 wherein the control message is transmitted on a common channel.

5. The method of claim 4, wherein the control message is repeatedly transmitted a predetermined number of times using the identical identifier.

6. A method of receiving control information for a multimedia broadcast/multicast service (MBMS) by a user equipment (UE) in a mobile communication system including the UE and a radio network controller (RNC) for providing the MBMS to the UE, the method comprising the steps of:

determining whether to respond to a paging message by using operation instruction information for instructing whether to respond to the paging message; and

transmitting response information to the RNC according to the operation instruction information included in the paging message.

7. The method of claim 6, wherein the operation instruction information includes state transition instruction information representing whether to respond to the paging message for the UE.

8. The method of claim 6, wherein the operation instruction information includes a generation cause of the paging message.

9. A method for transmitting control information for a multimedia broadcast/multicast service (MBMS) by a radio network controller (RNC) in a mobile communication system including a user equipment (UE) and the RNC providing the MBMS to the UE, the method comprising the steps of:

if a control message to be transmitted to UEs requesting the MBMS service is generated, transmitting to the UEs a paging message including operation instruction information instructing operation of the UEs according to a characteristic of an area where the UEs receive the MBMS service; and

transmitting the control message to the UE after transmission of the paging message including operation instruction information.

10. The method of claim 9, wherein the operation instruction information includes information instructing whether to perform state transition of the UEs when the paging message is received.

11. The method of claim 9, wherein the characteristic of the area where the MBMS service is provided is a non-tracking area where one of a cell update and a radio resource control (RRC) connection setup of the UEs is not performed, and is a tracking area where one of a cell update and an RRC connection setup of the UEs is performed.

12. The method of claim 9, wherein the characteristic of the area where the MBMS service is provided is determined according to MBMS service type.

13. The method of claim 9, wherein the characteristic of the area where the MBMS service is provided is determined according to a number of the UEs requesting the MBMS service.

14. The method of claim 9, wherein each of the UEs receives the paging message, and determines whether to perform one of a cell update and an RRC connection setup according to the operation instruction information included in the received paging information.
