Description
Technical field
The present invention relates to multimedia broadcast multi-broadcasting business (MBMS, Multimedia Broadcast MulticastService) technology, refer to a kind of method and system of the MBMS of realization service dispatching especially.
Background technology
Along with the fast development of the Internet and popularizing of large-screen multi-functional mobile phone, a large amount of mobile data multimedia services and various high bandwidth multimedia service have appearred, for example: video conference, television broadcasting, video request program, video ads, online education, interactive game etc.These mobile data multimedia services and high bandwidth multimedia service have not only satisfied the business demand that the mobile subscriber constantly rises, and have also brought new business growth point for mobile operator simultaneously.
Mobile data multimedia service and various high bandwidth multimedia service require a plurality of users can receive identical data simultaneously, compare with general data service, have characteristics such as data volume is big, longer duration, delay sensitive.In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rdGeneration Partnership Project) multimedia broadcast multi-broadcasting business (MBMS has been proposed, MultimediaBroadcast Multicast Service), the MBMS business is a kind of technology that transmits data from a data source to a plurality of targets, realize sharing of network (comprising core net and Access Network) resource, improved the utilance of Internet resources (especially air interface resource).The MBMS business of 3GPP definition not only can realize the classes of messages multicast and the broadcasting of plain text low rate, can also realize the broadcasting and the multicast of high-speed multimedia business, multiple rich video, audio frequency and multimedia service are provided, this has complied with the trend of following mobile data development undoubtedly, for the development of third generation digital communication (3G, 3rd Generation) provides better professional prospect.
At present, in Long Term Evolution version 9 (LTE R9) system, introduced the MBMS business.The MBMS business is carried in system needs the common transmission of control signaling and user data to realize.Wherein, the control signaling will be informed receiving terminal (or terminal, subscriber equipment (UE, User Equipment)) control corresponding parameter, guides UE to go to receive its interested MBMS business (being corresponding user data) to corresponding position.This control signaling is by multicast control channel (MCCH in LTE R9 system, Multicast Control Channel) transmits, the MBMS business is to transmit by multicast service channel (MTCH, Multicast Traffic Channel).MBMS control signaling and MBMS business are to carry out area dividing with multicast single frequency network (MBSFN, MBMS over a Single Frequency Network) zone (MBSFN Area), and wherein MBSFN Area is made up of a series of sub-district.
Specifically, a MBSFN zone comprises that one or more are by the sub-district under evolution base station (eNB) control.Fig. 1 is existing MBSFN zone logical schematic, and as shown in Figure 1, a MBSFN zone (in circle) comprises 19 sub-districts, and wherein, adopting the left tiltedly sub-district of shadow representation is the sub-district 1,2 of eNB1 control ..., 6; Adopting the right tiltedly sub-district of shadow representation is the sub-district 7,8 of eNB2 control ..., 13; The sub-district of adopting the lattice shadow representation is the sub-district 14,15 of eNB3 control ... 19.
Because in the prior art, in MBSFN Area (19 sub-districts in the circle have constituted a MBSFN zone), send control signaling and user data is to be unit with sub-district or eNB, use the MBSFN technology to carry out synchronized transmission (purpose makes UE can obtain the corresponding gain that merges when receiving), therefore, each sub-district sends identical data content in the MBSFN specification requirement MBSFN area on identical running time-frequency resource, so just need carry out unified scheduling and planning to the resource of each sub-district.What use in the prior art is unified scheduling and the planning that many sub-districts/multicast coordination entity (MCE, Multi-cell/multicast Coordination Entity) network element carries out Radio Resource, and specific implementation can be with reference to international standard 3GPP 36.300v910.Specifically, the transmission of the MBMS business in MCE control whole M BSFN zone, that is: MCE determines the MBMS business that sends on the MBSFN subframe in this MBSFN zone, and is controlled the emission of the MBMS business of each sub-district under its control by eNB.
The MBMS business (MTCH) that MBSFN zone of MCE configuration is carried and the multicast resource of control signaling (MCCH) are MBSFN subframe (subframe) and MBSFN frame (frame).A plurality of eNB under MCE covers are (as the eNB1 among Fig. 1, eNB2, eNB3) by system broadcast message, with these multicast resource distributions in all sub-districts (as the sub-district among Fig. 11,2, ..., 19), simultaneously, broadcast multicast service center (BM-SC, Broadcast Multicast Service Centre) with the MBMS business datum also by MBMS gateway (MBMS-GW) send among a plurality of eNB in this MBSFN zone (as the eNB1 among Fig. 1, eNB2, eNB3).Herein, with transmission path BM-SC-＞MBMS-GW-＞eNB, be called user plane data transfer (being used for transferring MBMS service data), with transmission path BM-SC-＞MBMS-GW-＞MCE-＞eNB, be called chain of command signaling transmission (being used to dispose Control Parameter such as multicast resource), specifically as shown in Figure 2, Fig. 2 is the logical schematic of MBMS service bearer framework in the prior art, wherein M1 is interface in the user plane (user plane interface), and M2 is E-UTRAN chain of command interface (E-UTRAN internal control plane interface), M3 is the chain of command interface (control plane interface between E-UTRAN andEPC) between E-UTRAN and EPC.
A certain specific cell may be covered the usually said overlapping covering of MBSFN Area (overlapping) that Here it is simultaneously by a plurality of MBSFN Area.At present, the overlapping covering of 1 to 8 MBSFN Area is supported in the sub-district.Wherein, the sub-district is the least unit that MBSFN Area covers, and an eNB may corresponding a plurality of sub-districts.
When there was overlapping coverage condition in a certain sub-district, this sub-district just may have a plurality of MCCH (because each MBSFN Area is corresponding MCCH) simultaneously.For each specific MCCH, all have MCCH and revise the cycle (MP, Modification Period), and in MCCH MP, the content that MCCH carried does not allow to change; In MCCH MP, what MCCH information also will repeat sends, and wherein the time interval of Fa Songing is referred to as the MCCH repetition period (RP, Repeat Period), and repeating to send with the repetition period mainly is in order to improve the reliability that UE receives MCCH information; The relation of MCCH MP and MCCH RP as shown in Figure 3, Fig. 3 be in the prior art MCCH MP and MCCH RP concern schematic diagram, in MCCH MP (n), the content that MCCH sends can not change, can only arrive next MCCH MP place and just may change, MCCH RP represented in MCCHMP MCCH content repeat send.UE is by Broadcast Control Channel (BCCH, Broadcast ControlChannel) system information block 13 (SIB13, System Information Block) can know MCCH all in this sub-district with and corresponding configuration information, such as how many bar MCCH, relevant parameters such as the MP of every MCCH, RP are arranged in this sub-district.
MCCH and MBSFN Area are one to one.UE just can be known the control information of the MBSFN Area corresponding with it by reading MCCH message, such as the multicast subframe configuration information of resource of this MBSFN Area, the all-network side has begun to send Control Parameter such as parameter MBMS-SessionInfo-r9, sessionId-r9, the serviceId-r9 etc. of the MBMS service of the MBMS business of (ongoing) and ongoing among this MBSFN Area.
Multicast Channel (MCH) is a transmission channel, the transmission of putting multiple spot, and the corresponding physical resource is that system is the multicast resource that the MBMS transmission business is distributed.A carrier frequency can carry a plurality of MCH, the physical channel that carries specific MCH is that the subframe by a picture group sample is determined, these subframes may not be the time continuous dispensing, this pattern is called as the sub-frame allocation pattern (MSAP of Multicast Channel, MCH subframeallocation pattern), a MSAP describes the physical resource of a MCH channel.In the LTE system, the multicast resource in each MBSFN zone can be that unit divides according to certain pattern with the subframe, and the indicated resource of each pattern constitutes a MCH.
Multicast service channel (MTCH, Multicast Traffic Channel) be logic channel, a MTCH carries one or more business data of (being called a business such as a TV program), a business only is carried among the MTCH, MTCH is mapped on the MCH and transmits, one or more MTCH can be mapped on one or more MCH, and promptly a plurality of MBMS business can be mapped on the MCH.
The feature that adopts many sub-districts sending mode to carry out the MBMS transmission comprises, in the inter-sync transmission of MBSFN zone; Support the merging of many cell MBMS transmission data; MTCH and MCCH are mapped to the MCH transmission channel under the p-T-m pattern first-class.
By MSAP information, UE can be known the pairing concrete multicast resource of a certain concrete MCH, but, owing to comprised one or more MBMS business datums (such as one or more MTCH) among the MCH, so, need specifically indicate the professional pairing concrete physical resource of a certain MBMS by the MBMS dynamic scheduling information.Like this, UE is receiving a certain specific MBMS when professional (such as the professional MTCH1 of the interested MBMS of this UE), just can know the definite resource of this MBMS business by the indication of MBMS dynamic scheduling information, thereby realize the accurate reception of MBMS business, and for other multicast subframe among the MCH (such as the multicast subframe of the non-MTCH1 of carrying), UE keeps silent status, does not receive its sub-frame information, thereby has realized that UE saves the purpose of energy consumption.
In the existing disclosed technology, the resource that the MBMS dynamic scheduling information is dispatched or administered is defined as the dynamic dispatching cycle (Schedule period) on time span, such as 320ms, 640ms etc.Fig. 4 is the setting of Scheduling Block in the dynamic dispatching cycle and the logical relation schematic diagram of MBMS business in the prior art, as shown in Figure 4, the horizontal line shadow representation Scheduling Block of overstriking wherein, the MBMS that other shadow representation is different is professional as MBMS service A, MBMS service B among the figure and MBMS service C, and blank parts represents not have data or filler.
In the transmission course of MBMS business, the application of up feedback also is important techniques means in the prior art; Up feedback is meant, by network side trigger or UE voluntarily by uplink feedback channel, with/some status attribute of preparing to receive the UE of MBMS business reports network side, receive/the MBMS service identification of reception interested such as UE); By the information that UE reports, the UE that network side can be known its subordinate is comparatively detailed information at present, such as receiving in certain sub-district among the MBSFN area/number of users of a certain MBMS business of reception interested; Network side can carry out some by the information that obtains adjustment or scheduling of resource are set, such as the transmission of a certain MBMS business of On/Off.The typical application example is: among the MBSFN area each eNB require respectively its subordinate UE feed back its/the MBMS Business Name (triggering up process of feedback) that prepare to receive by eNB, / prepare to receive the MBMS business UE can uplink feedback channel with its/prepare to receive the MBMS service identification, such as the MBMS traffic ID etc., feed back to the eNB under it.Each eNB is according to the information that obtains, such as receiving/number of users of a certain MBMS business of reception interested, be not lower than threshold value etc. as may having the user among the eNB in MBSFN area receiving this MBMS number of users professional or that receive this MBMS business in conjunction with criterion again, decide unlatching or the shutoff of this MBMS business datum on eNB.
In the professional transmission course of existing MBMS, during to the MBMS service dispatching, the MBMS Service coverage is that transmit on the basis with its pairing MBSFN area, and promptly the professional pairing MBSFN area of this MBMS comprises several sub-districts, and this MBMS business will be transmitted in these sub-districts.Consider that the MBMS business carries the complexity of transmission (for example: need unified scheduling of resource, user face data synchronous transmission, scheduling of resource for the influence of system information etc.) in MBSFN area, at present, the professional pairing MBSFN area of MBMS is in case by operation management maintain (OAM, Operation, Administration and Maintenance) configure after, will can not change again or seldom change.
As can be seen, for a certain concrete MBMS business among the MBSFN area, will in whole M BSFN area, transmit; And in actual applications, it is also unwanted sometimes that a certain MBMS business sends in whole M BSFNarea, for example, may not have the user in this MBMS business of reception in MBSFN area certain/a little sub-districts, or the number of users that receives this MBMS business is when being lower than threshold value, if this MBMS is professional to be continued at this/send in a little sub-districts, and reduce utilization ratio of wireless resources undoubtedly, and caused the waste of transmitting power.
