Multimedia broadcast multicast service scheduling and transmission method and system

A system for scheduling and transmitting a Multimedia Broadcast Multicast Service (MBMS), comprising a lower layer network element and a user equipment, wherein:

• said lower layer network element is configured to:
• for each multicast radio interface channel, schedule data of the MBMS and generate scheduling information on multiple Multicast/Broadcast over Single Frequency Network (MBSFN) subframes occupied by the multicast radio interface channel in multiple resource allocation periods corresponding to a scheduling period of the multicast radio interface channel, wherein the scheduling period is used for dynamical multiplexing of the MBMS and one scheduling period corresponds to multiple resource allocation periods in a same time period, location information of the data of each MBMS in said scheduling information is represented by a number of a first or a last MBSFN subframe occupied by the data of the MBMS in the scheduling period, or by a number of occupied MBSFN subframes in the scheduling period, wherein numbers of the MBSFN subframes are obtained by sequentially numbering with consecutive integers all the MBSFN subframes of the multiple resource allocation periods occupied by the multicast radio interface channel in each scheduling period independently;
• indicate resource allocation information and scheduling period information of each multicast radio interface channel in signaling sent to the user equipment, and send the data of the MBMS and said scheduling information to the user equipment;
• said user equipment is configured to:
• acquire a MBSFN subframe occupied by the multicast radio interface channel where the MBMS to be received is located in the scheduling period according to the scheduling information and the resource allocation information of the multicast radio interface channel in a received signaling, receive said scheduling information on a sending location of the scheduling information of the located multicast radio interface channel, and further receive the data of said MBMS to be received according to an indication of said scheduling information.

A lower layer network element for supporting scheduling and transmitting a Multimedia Broadcast Multicast Service (MBMS), configured to:

• for each multicast radio interface channel, schedule data of the MBMS and generate scheduling information on multiple Multicast/Broadcast over Single Frequency Network (MBSFN) subframes occupied by the multicast radio interface channel in multiple resource allocation periods corresponding to a scheduling period of the multicast radio interface channel, wherein the scheduling period is used for dynamical multiplexing of the MBMS and one scheduling period corresponds to multiple resource allocation periods in a same time period, location information of the data of each MBMS in said scheduling information is represented by a number of a first or a last MBSFN subframe occupied by the data of the MBMS in the scheduling period, or by a number of occupied MBSFN subframes in the scheduling period, wherein numbers of the MBSFN subframes are obtained by sequentially numbering with consecutive integers all the MBSFN subframes of the multiple resource allocation periods occupied by the multicast radio interface channel in each scheduling period independently;
• indicate resource allocation information and scheduling period information of each multicast radio interface channel in a signaling sent to a user equipment, and send the data of the MBMS and said scheduling information to the user equipment, so that said user equipment acquires a MBSFN subframe occupied by the multicast radio interface channel where the MBMS to be received is located in the scheduling period according to the scheduling information and the resource allocation information of the multicast radio interface channel in a received signaling, receives said scheduling information on a sending location of the scheduling information of the located multicast radio interface channel, and further receives the data of said MBMS to be received according to an indication of said scheduling information.
