ABSTRACT:
A method for enabling a user equipment (UE) to recover from a multimedia broadcast/multicast service (MBMS) data error in a mobile communication system. The mobile communication system includes a radio network controller (RNC) and at least one cell for transmitting MBMS data to at least one UE according to a control operation of the RNC. The RNC transmits first control information to UEs located in each cell. Each of the UEs receives the first control information and the MBMS data. When an error in the received MBMS data is detected, the RNC is notified that an MBMS data reception error has occurred. Response information associated with the MBMS data reception error is transmitted from the UE to the RNC. The UE determines whether control information contained in the response information matches the first control information. The MBMS data reception error is recovered from, according to a result of the determination.
