Description
Technical field
The present invention relates to Long Term Evolution (Long Term Evolution, be called for short LTE) field, in particular to transmission method and the system of a kind of MBMS (Multimedia Broadcast Multicast Service, multimedia broadcasting and multicast service) business.
Background technology
Along with the fast development of Internet and the universal of large-screen multi-functional mobile phone, a large amount of Mobile data multimedia service and various high bandwidth multimedia service are there is, such as, video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., this meets the business demand that mobile subscriber constantly rises on the one hand, on the other hand also for mobile operator brings new business growth point.The multiple user of these Mobile data multimedia service requirements can receive identical data simultaneously, compared with general data service, has the features such as data volume is large, duration length, delay sensitive.In order to effectively utilize mobile network resource, third generation partner program 3GPP proposes MBMS, this business is a kind of technology transmitting data from a data source to multiple target, achieve sharing of network (comprising core net and Access Network) resource, improve the utilance of Internet resources (especially air interface resource).The MBMS of 3GPP definition can not only realize classes of messages multicast and the broadcast of plain text low rate, but also broadcast and the multicast of high-speed multimedia service can be realized, multiple abundant video, audio frequency and multimedia service are provided, this has complied with the trend of following Mobile data development undoubtedly, and the development for 3G provides better business prospect.
At present, in Long Term Evolution version 9 (LTE R9) system, MBMS is introduced.MBMS carries in systems in which and needs the common transport of control signal and user data to realize.Wherein, control signal will inform receiving terminal (or terminal, subscriber equipment (UE, User Equipment)) corresponding controling parameters, guides UE to receive its interested MBMS (i.e. corresponding user data) in corresponding position.(the control information of this MBMS control signal, comprise: the configuration information etc. of MBMS) be by multicast control channel (MCCH in LTE R9 system, Multicast Control Channel) carry out transmitting, MBMS (or being referred to as MBMS data) is undertaken transmitting by Logical Traffic Channels (MTCH, Multicast Traffic Channel).Particularly, the MBMS control signal (i.e. MCCH information) that logic channel MCCH transmits mainly comprises: the multicast single frequency network (MBSFN corresponding to MCCH information, MBMS overa Single Frequency Network) multicast resource in region, in this MBSFN region, all (ongoing) MBMS sent (or are referred to as the MBMS that started, or be referred to as the MBMS of session start), and the configuration of ongoing MBMS and attribute information; In logic channel MTCH carrying is MBMS data, generally MBMS and MTCH are carried out corresponding (such as: MBMS 1 is corresponding with MTCH1, MBMS 2 is corresponding with MTCH2), that is, what UE read that MBMS and UE read that MTCH expresses is identical implication.
MBMS control signal (MCCH information) and MBMS data with MBSFN region for scope sends; MCCH and MBSFN region is one to one, and that is the corresponding MCCH information content sent in different MBS FN region is not identical; Wherein, MBSFN region is made up of a series of community.Specifically, a MBSFN region comprises one or more by the community under evolution base station (eNB) control.Fig. 1 is existing MBSFN region logical schematic, and as shown in the figure, this MBSFN region comprises 19 communities, wherein, and the community that community 1 to 6 controls for eNB1; The community that community 7 to 13 controls for eNB2; The community that community 14 to 19 controls for eNB3.Community is the basic concept of field of wireless communication, indicates the coverage of wireless signal in logic; Community is that operator plans when carrying out network design, the mark Cell ID that each community has it unique, its Cell ID will pass through Broadcast Control Channel (BCCH, Broadcast ControlChannel) information and send in community.
According to prior art, important network element involved by the transmission of MBMS comprises: BM-SC (Broadcast MulticastService Centre, broadcast multicast service center), MME (Mobility Management Entity, mobile management entity), MCE (Multi-cell/multicast Coordination Entity, multiple cell/multicast coordinated entity), eNB, MBMS GW; Wherein, BM-SC, as core network element, will trigger the transmission of MBMS.In addition, when BM-SC initiates a MBMS transmission, the MBMS Service Area scope of this business will be provided, this scope specifies (Uu mouth on eating dishes without rice or wine, or be referred to as wireless side) range of transmission of this MBMS, BM-SC is by using the MBMS Service Area (wherein being forwarded by MME) of MBMS Session Start Request message instruction MCE business.After MCE receives the MBMS Session Start Request message comprising MBMSService Area, the content of MBMS Service Area can be corresponded to corresponding MBSFN area to get on, and corresponding MCCH information and MBMS data are sent on corresponding MBSFN area.
In current techniques is discussed, introduce the concept of MBMS effective coverage; MBMS effective coverage (being also called local information, local information) refers to coming into force or useful region of MBMS; Consider that prior art MBMS can send in whole MBSFN area, and the scope of MBMS effective coverage is generally little compared with MBSFN area.The feature of MBMS effective coverage can change flexibly (MBSFN area is static configuration), and instruction MBMS is effective for UE in those regions; That is, although MBMS all sends in whole MBSFN area, for UE, by the information of MBMS effective coverage, concrete business effective coverage can be known, the power consumption that UE blindness reception MBMS is brought can be reduced.That is in effective coverage, this MBMS just comes into force, and can be received by UE; Outside effective district and in MBSFN area, although UE equally also can receive this MBMS, the MBMS received, for being a kind of hash UE or bothering, adds the power consumption of UE.
The logical schematic of concrete MBMS ServiceArea (MBMS region), MBSFNArea (MBSFN region) and MBMS effective coverage as shown in Figure 2.Wherein BM-SC indicates the area size (as shown in phantom in Figure 2) of MBMS Service 1 Area (MBMS 1 region) of MBMS Service 1 (MBMS 1); MBMS Service 1 Area is corresponded to corresponding MBSFN Area (as shown in MBSFN Area in Fig. 21,2,3) by MCE; In addition, Fig. 2 gives the effective coverage of MBMS Service 1.
Current Problems existing is: under existing MBMS transmit mechanism or framework, how effectively to introduce the related content of MBMS effective coverage, provide a kind of method for expressing of rationally efficient MBMS effective coverage, realize the object introducing MBMS effective coverage.
