Problems solved by technology

[0004] However, in the existing 3GPP protocol architecture, since the DeNB cannot transmit Multimedia Broadcast Multicast Service (MBMS) data to the relay node RN, the existing 3GPP protocol architecture cannot realize the transfer of MBMS data between the DeNB and the DeNB. Transfer between RNs

Abstract

The invention provides an MBMS data transmission method and system, a donor base station and a relay node, and belongs to the technical field of communication. The MBMS data transmission method comprises the following steps: establishing a first M1 interface with a multimedia broadcast multicast service gateway MBMS GW; establishing a second M1 interface with the relay node RN; receiving MBMS datasent by the MBMS GW via the first M1 interface; and sending the MBMS data to the RN via the second M1 interface. By adoption of the MBMS data transmission method and system, donor base station and relay node, the transmission of the MBMS data between the DeNB and the RN is achieved in 3GPP protocol architecture.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an MBMS data transmission method, a donor base station, a relay node and a system. Background technique [0002] In order to solve network deployment costs and coverage issues, standardization organizations have begun to study introducing relay nodes (Relay Node, RN for short) into cellular systems, thereby increasing network coverage. In the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) protocol framework, including mobile management node (Mobility ManagementEntity, referred to as MME), serving gateway (Serving-GateWay, referred to as S-GW), evolved base station (evolved Node B, referred to as eNB) and a relay node (Relay Node, referred to as RN). [0003] Specifically, after the RN accesses the cell controlled by the donor eNB (DeNB for short), the DeNB acts as the S1 / X2 proxy of the RN, and can realize the forwarding of th...
