The 3rd Generation Partnership Project (3GPP) Technical Specification 23.246 proposed the Multimedia Broadcast Multicast Service (MBMS) that efficiently multicasts multimedia content. During MBMS content transmission, data may be lost. Three file repair schemes were proposed to retransmit the corrupted MBMS data. However, these schemes may introduce extra data traffic or signaling overheads. This paper proposes the Reuse Bearer Service (RBS) file repair scheme to resolve this issue. We analyze the four file repair schemes by analytical models and simulation experiments. This paper shows that the proposed RBS scheme may significantly outperform the previously proposed schemes.
