Abstract:
A file repair method for Multimedia Broadcast Multicast Service (MBMS) and a UMTS network are disclosed. According to the method, a data structure is established according to a repair request message sent from a user equipment. Each repair block is multicast to the user equipment that requested it by using the original MBMS Bearer Service for file downloading according to the data structure. The present invention does not need any extra traffic and additional control signaling to allow each user equipment to receive required repair blocks.
