Method of transmitting/receiving control message in a mobile communication system providing multimedia broadcast/ multicast service
First Claim
1. A method for receiving a broadcasting service in a user equipment (UE) in a mobile communication system where requested broadcasting services are provided to a plurality of UEs within a cell through a radio network controller (RNC), the method comprising the steps of:
- determining whether the broadcasting service is included in a broadcasting status message containing information about the types of ongoing broadcasting services for the cell, if the UE fails to receive control information about the broadcasting service from the RNC;
requesting the broadcasting service control information from the RNC if the broadcasting service is included in the broadcasting status message;
receiving the broadcasting service control information from the RNC; and
receiving the broadcasting service according to the broadcasting service control information.

Abstract
A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.

9. A method for providing a broadcasting service to a user equipment (UE) in a radio network controller (RNC) in a mobile communication system where requested broadcasting services are provided to a plurality of UEs within a cell through the RNC, the method comprising the steps of:
-
transmitting to the UE a broadcasting status message containing information about the types of ongoing broadcasting services for the cell;
receiving a request for control information about the broadcasting service from the UE, if the UE finds the broadcasting service in the broadcasting status message and recognizes that the UE failed to receive the broadcasting service control information;
transmitting the broadcasting service control information to the UE; and
confirming that the UE received the broadcasting service control information. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method for providing a packet data service to at least one user equipment (UE) in a radio network controller (RNC) in a mobile communication system where the packet data service is provided to the at least one UE upon request from the at least one UE, the method comprising the steps of:
-
transmitting to the at least one UE a paging indicator indicating that the at least one UE will be paged, paging information paging the at least one UE in correspondence with the paging indicator, and radio bear information for the packet data service; and
retransmitting the paging indicator, the paging information, and the radio bearer information in every predetermined period until the packet data service is terminated. - View Dependent Claims (18, 19, 20, 21)

22. A method for receiving a packet data service in a user equipment (UE) in a mobile communication system where requested packet data services are provided to a plurality of UEs within a cell through a radio network controller (RNC), the method comprising the steps of:
-
receiving from the RNC a paging indicator that the UE will be paged in connection with the packet data service, paging information according to the paging indicator, and radio bear information for the packet data service; and
receiving packet data for the packet data service from the RNC without transmitting a response control message for the radio bearer information to the RNC. - View Dependent Claims (23)
