Technical field
The present invention relates to multimedia broadcasting and multicast service (MBMS, Multimedia Broadcast MulticastService), espespecially a kind of method and subscriber equipment that obtains MBMS dynamic scheduling information.
Background technology
Along with the fast development of 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 been there is, such as video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., met on the one hand the business demand that mobile subscriber constantly rises, simultaneously also for mobile operator brings new business growth point.These Mobile data multimedia services require a plurality of users can receive identical data simultaneously, and Mobile data multimedia service is compared with general data service, have 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, 3rd GenerationPartnership Project) has proposed MBMS business.MBMS business provides a data source to a plurality of users, to send the point-to-multipoint service of data in mobile network, has realized Internet resources and has shared, and has improved the utilance of Internet resources.The MBMS of 3GPP definition not only can realize classes of messages multicast and the broadcast of plain text low rate, but also can realize broadcast and the multicast of high-speed multimedia business, and multiple abundant video, audio frequency and multimedia service are provided.
In Long Term Evolution (LTE, Long Term Evolution) system, the data channel of MBMS business and control channel can adopt sending mode He Duo community, single community sending mode.Wherein, single community sending mode refers to that the data channel of MBMS business and control channel Jin Zhe community send, and do not have the function of the grand diversity of Multicast Broadcast Single Frequency Network (MBSFN, Multicast Broadcast Single Frequency Network); Er Duo community sending mode refers to that a plurality of communities send identical data on identical running time-frequency resource, i.e. MBMS business or control information adopted the mode of content synchronization, namely adopted the grand diversity of MBSFN.By many communities sending mode, a plurality of communities are sending data or the control signal of the MBMS business of identical content mutually in the same time, can improve the receiving gain of subscriber equipment (UE, user equipment).
Multicast Channel (MCH) is transmission channel, carries out point-to-multipoint transmission, and corresponding physical resource is that system is the multicast resource that 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 determines, these frames may not be that Time Continuous distributes, 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 LTE system, the multicast resource in each MBSFN region can be take subframe and according to certain pattern, divided as unit, and the indicated resource of each pattern forms a MCH.
Multicast transmission channel (MTCH, Multicast Traffic Channel) be logic channel, a MTCH carries the data of one or more business (such as a TV program is called a business), a business is only carried in a MTCH, MTCH is mapped on MCH and transmits, it is upper that one or more MTCH can be mapped to one or more MCH, and a plurality of MBMS business can be mapped on a MCH.
The feature that adopts many communities sending mode to carry out MBMS transmission comprises, in the inter-sync of MBSFN region, transmits; Support the merging of many cell MBMS transmission data; It is first-class that MTCH and MCCH are mapped to MCH transmission channel under p-T-m pattern.
By MSAP information, UE can be known the corresponding concrete multicast resource of a certain concrete MCH, but, owing to having comprised one or more MBMS business datums (such as one or more MTCH) in MCH, need to specifically indicate the corresponding concrete physical resource of a certain MBMS business by MBMS dynamic scheduling information.Like this, UE is (such as the interested MBMS business of this UE MTCH1) when receiving a certain specific MBMS business, just can know by the indication of MBMS dynamic scheduling information the definite resource of this MBMS business, thereby realize accurately, receive, and for other multicast subframe in 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 the object of UE saving energy consumption.
In existing public technology, MBMS dynamically transfers the resource that information dispatches/administer and in time span, is defined as dispatching cycle (Schedule period), such as 320ms, 640ms etc.Fig. 1 a is the setting of existing Scheduling Block in dispatching cycle and the logical relation schematic diagram of MBMS business, Fig. 1 b is the schematic diagram that is related to of the setting of existing Scheduling Block in dispatching cycle and MBMS business, the horizontal line shadow representation Scheduling Block of overstriking in Fig. 1 a and Fig. 1 b, the different MBMS business of other shadow representation is as the MBMS business 1 in figure, MBMS business 2 and MBMS business 3, and blank parts represents not have data or filler.What agreement regulation had been shown in Fig. 1 b can not be for the subframe of bearing MBMS service as subframe 0, subframe 4, subframe 5 and subframe 9.
As shown in Fig. 1 a and Fig. 1 b, the assignment information of network side configuration multicast subframe, the schedule information that comprises all business in this dispatching cycle in Scheduling Block wherein (schedule block), and Scheduling Block sends at the initial position of whole dispatching cycle, the scope of scheduling resource be this dispatching cycle of interior all MBMS business.Initial position can be first multicast subframe of this dispatching cycle or corresponding physical resource.
