Abstract
A method, system and device for supporting enhanced Multimedia Broadcast Multicast Service (eMBMS) in a relay network are disclosed. The method includes that: a network side sends a message to a relay node used to indicate a position of a Multicast Broadcast over Single Frequency Network (MBSFN) subframe relates to the eMBMS in a transmission frame; the relay node determines the position of the MBSFN subframe in the transmission frame according to the message, and makes the MBSFN subframe silent according to the determinate position; when a user terminal determines the existence of the MBSFN subframe made silent by the relay node in the transmission frame sent from the relay node, the user terminal receives the eMBMS sent by device except the relay node according to control information of the received eMBMS, thereby avoids the influence of the relay node to the user terminal supporting eMBMS.
