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.

A method for supporting an enhanced multimedia broadcast multicast service, eMBMS, in a relay network, comprising:

receiving, by a relay node, a message for indicating a position of an Multicast/Broadcast over Single Frequency Network, MBSFN, sub-frame related to the eMBMS in a transmission frame, which is sent from a network-side device;
acquiring, by the relay node, the position of the MBSFN sub-frame in the transmission frame according to the received message;
and muting, by the relay node, the MBSFN sub-frame according to the determined position of the MBSFN sub-frame in the transmission frame;
determining, by a user equipment, whether there is the MBSFN sub-frame muted by the relay node in the transmission frame sent from the relay node;
and
receiving, by the user equipment, an eMBMS sent from a device other than the relay node according to a received control information of the eMBMS in the case that the user equipment determines that there is the muted MBSFN sub-frame.

A system for supporting an enhanced multimedia broadcast multicast service, eMBMS, in a relay network, comprising a network-side device, a relay node and a user equipment, wherein

the network-side device is configured to send to the relay node a message for indicating a position of an MBSFN sub-frame related to the eMBMS in a transmission frame;
the relay node is configured to acquire the position of the MBSFN sub-frame in the transmission frame according to the message sent from the network-side device, and mute the MBSFN sub-frame according to the determined position;
and
the user equipment is configured to determine whether there is the MBSFN sub-frame muted by the relay node in the transmission frame sent from the relay node, and receive the eMBMS sent from a device other than the relay node according to the received control information of the eMBMS.
