202, base station assigns multicast and broadcast subframe (Broadcast/Multicast Subframe, BMS) as service subframe, BMS comprises control channel and data channel, the business datum that data channel comprises eMBMS business, control channel comprises the user terminal of instruction in MBSFN region and receives from data channel the indication information of business datum.
204, base station assigns clean culture subframe, as service subframe, is carried eMBMS business datum.
203, service subframe is inserted downlink data frame sequence by base station, in MBSFN region, sends downlink data frame sequence to user terminal.
BMS comprises control channel and data channel, control channel can be Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH), data channel can be Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH).User terminal in MBSFN region can, monitoring and receive BMS, according to the indication information of control channel, go corresponding frequency to receive the business datum of eMBMS business.
User terminal obtains the embodiment of corresponding business datum by clean culture subframe, can realize according to the execution mode known to those skilled in the art.
The method providing based on above-described embodiment, by introducing multicast and broadcast subframe BMS as the service bearer unit under multicast and broadcast mode in scheduling of resource, base station is according to the number of users of subscribing to eMBMS business in MBSFN region, in the time that number of users meets the first broadcast threshold condition, distribute BMS as service subframe carrying eMBMS business datum, adopt multicast and broadcast mode, in the time not meeting the first broadcast threshold condition, use clean culture subframe as service subframe carrying eMBMS business datum, adopt mode of unicast, thereby the scheduling mode of base station can be switched neatly between multicast and broadcast mode and mode of unicast.

Shown in Figure 4, this illustrates the schematic flow sheet of a kind of embodiment of resource regulating method of long evolving system Multimedia Broadcast Multicast Service provided by the present invention.Compared with embodiment illustrated in fig. 2, in the operation 202 of Fig. 2, do not meet the first broadcast threshold condition in response to number of users, the method also comprises: 401, whether the service quality QoS of identification of base stations eMBMS business meets the second predetermined broadcast threshold condition;
Meet the second predetermined broadcast threshold condition in response to QoS, 202 operation is carried out in base station, distributes the operation of BMS as service subframe; Otherwise, carry out 204 operation, distribute the operation of clean culture subframe as service subframe.
The service quality QoS of different e MBMS business is conventionally corresponding to different service priority, and the business of high QoS has high priority.For the QoS of different e MBMS business, can adopt multicast and broadcast mode or mode of unicast that the business service of different quality is provided.For the eMBMS business of higher QoS, can adopt multicast and broadcast mode, distribute the user terminal of BMS to all these business of subscription under this base station, because base station in MBSFN region is all used multicast and broadcast mode, use BMS multicast and broadcast to send eMBMS business datum, increased the correct probability receiving of user terminal.Anyway, base station adopts mode of unicast, because business has lower qos requirement, even if single subframe receives wrong or loses, also still can accept.Thus, the QoS having for different e MBMS business, makes different eMBMS business obtain the business service of different quality.
For example, the number of users of current subscription eMBMS business is few, and the QoS of this business is lower, be that service priority is not high, do not meet the second predetermined broadcast threshold condition, base station is carried out and is distributed the operation of clean culture subframe as service subframe, by unicast schedule scheme, sends this eMBMS business datum.But even if it is few to subscribe to the number of users of eMBMS business, but the QoS of business is higher, meet the second predetermined broadcast threshold condition, base station also starts multicast and broadcast mode, distributes the user terminal of BMS subframe to all these business of subscription under this base station, so that the business service of multicast and broadcast mode to be provided.
According to a kind of concrete example of the inventive method embodiment, in Fig. 4 embodiment method, can also comprise that following operation obtains the QoS of eMBMS business:
Base station receives the notification message of the QoS that comprises eMBMS business of core network element propelling movement; Or base station is to the QoS of core network element inquiry eMBMS business, the Query Result message of returning according to core network element, obtains the QoS of eMBMS business.
Shown in Figure 5, this illustrates the schematic flow sheet of a kind of embodiment of resource regulating method of long evolving system Multimedia Broadcast Multicast Service provided by the present invention.Compared with embodiment illustrated in fig. 4, do not meet the second broadcast threshold condition in response to number of users, the method also comprises: 501, and between identification of base stations user terminal and base station, whether the channel quality indicator CQI of communication channel meets the 3rd predetermined broadcast threshold condition.
Meet the 3rd predetermined broadcast threshold condition in response to CQI, 202 operation is carried out in base station, distributes the operation of BMS as service subframe; Otherwise, carry out 204 operation, distribute the operation of clean culture subframe as service subframe.
CQI is as the measurement standard of quality of wireless channel, and the CQI that numerical value is high represents that channel has high quality.Under different channel qualities, adopt multicast and broadcast mode, mode of unicast in conjunction with channel quality, even in the situation that the quality of realization communication channel there are differences, also still can provide to user terminal the service quality of good eMBMS business.For example, in the situation that channel quality is low, can adopt to multicast and broadcast mode, avoid because clean culture subframe is lost or failed after correct reception, user terminal cannot obtain correct eMBMS business datum, increase the correct probability receiving of user terminal, guarantee to provide to user terminal the service quality of eMBMS business.Anyway,, in the situation that channel quality is high, can adopts to mode of unicast and use clean culture subframe.Therefore, can preset the 3rd corresponding broadcast threshold condition according to different CQI, when meeting the 3rd predetermined broadcast threshold condition, base station is carried out and is distributed the operation of BMS as service subframe; Otherwise execution step is distributed the operation of clean culture subframe as service subframe.
