Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of method and system of schedule information of transmitting multimedia broadcast multicast service.
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 appearred, for example, video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., this has satisfied the business demand that the mobile subscriber constantly rises on the one hand, also brings new business growth point for mobile operator simultaneously.These mobile data multimedia services 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 (3rd Generation Partnership Project, abbreviate 3GPP as) the MBMS business proposed, this 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 of 3GPP definition not only can realize the classes of messages multicast and the broadcasting of plain text low rate, but also can 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 3G provides better professional prospect.
In LTE, the MBMS business can adopt multicast pattern mode, be called MBSFN (Multicast/Broadcast over Single Frequency Network, single frequency network multicast broadcast) sending mode, the MBMS business that adopts the multicast pattern to take place, be also referred to as the MBSFN business, can be after identical modulation be adopted in a plurality of sub-districts coded format, adopt identical physical resource generation identical content.
The feature of MBMS cell transmission: 1) in the inter-sync transmission of MBSFN zone; 2) support many cell MBMS transmission to merge; 3) MTCH (Multicast traffic Channel, multicast service channel) and MCCH (Multicast Control Channel, multicast control channel) are mapped on the MCH transmission channel under p-T-m (putting multiple spot) pattern; 4) MBSFN retaining zone, the MBSNF zone, the MBSFN transmission, advertisement keeps the sub-district, by the semi-static configuration of Operation and Maintenance.The UE of a plurality of like this sub-districts (User equipment, subscriber equipment) can receive the identical MBMS data of a plurality of contents and carry out SFN and merge, thus the gain that can improve received signal.A plurality of sub-districts of adopting identical physical resource and adopting the MBSFN sending mode to send the same MBMS business have constituted a MBSFN zone.
In the LTE of reality networking, several MBSFN business are arranged on the MBSFN zone, these all MBSFN business that belong to same MBSFN zone are called a MBSFN service groups, that is to say that a MBSFN service groups only belongs to a MBSFN zone.A MBSFN zone comprises a plurality of sub-districts, and each sub-district has all disposed an identical MBSFN service groups.The data channel MTCH that possesses a plurality of MBSFN business in identical MBSFN zone, and the control channel MCCH of MBSFN business can be multiplexed into a MCH (Multicast Chnanel, Multicast Channel), promptly many logic channels can be mapped on the same transmission channel MCH.
As shown in Figure 1, in order to improve the transmitting efficiency of MTCH, each MTH goes up the method that a plurality of MTCH that carry can adopt dynamic dispatching, can the MTCH more than 2 or 2 is multiplexing on same MBSFN subframe and take the part resource of this subframe by dynamic dispatching, Fig. 1 (a), Fig. 1 (b) and Fig. 1 (c) are respectively the resource allocation schematic diagram of Scheduling Period 1, Scheduling Period 2, Scheduling Period 3.In the existing public technology, introduce MSAP occasion (MSAP opportunity) simultaneously in the MSAP notion, it has indicated the interior included whole multicast resources of the pairing MCH of certain MSAP of time period in a dynamic dispatching cycle.In a MSAPoccasion, can send a plurality of MTCH and dynamic scheduling information, can also comprise MCCH, dynamic scheduling information can carry and be used in MAC control section (MAC control element), perhaps be carried on independent logic channel MSCH (Multicast scheduling channel, the multicast scheduling channel), MSAP occasion length generally is fixed as 320ms, similarly, generally being fixed as 320ms a dispatching cycle, also can be 2
n* 320ms (n=-3 ,-2 ,-1,0,1,2,3,4.....N), correspondingly, MSAP occasion time span is 40ms, 80ms, 160ms, 320ms, 640ms, 1280ms or the like, a MSAP occasion time span is exactly a dispatching cycle, is also referred to as a dynamic dispatching cycle.Article one, MCH has distributed one or more MBSFN subframes in one or more MBSFN frames by MSAP, and the subframe that wherein adopts the multicast pattern to send is called the MBSFN subframe, and the frame that contains the MBSFN subframe is called the MBSFN frame.
On each MSAP occasion that MCH disposed, carried schedule information, it carries the map information of MTCH to auxiliary MSAP subframe, this map information is to determine by means of the relation of the MBSFN subframe numeral index in a dispatching cycle, UE reads schedule information can know which MBSFN subframe each MTCH is dispensed on, UE can read its interested MTCH on corresponding M BSFN subframe, do not need the MBSFN subframe that reads and ignore it, thereby the professional receiving efficiency of the MBMS that improves UE, the power consumption of saving UE.MBSFN subframe numbering described herein is to determine like this: all MBSFN subframes that a MCH was distributed in a dispatching cycle are arranged number consecutively in order.For example the MCH channel MBSFN number of subframes total amount of distributing in one-period is 100, and then the subframe numbering from 0 to 99, perhaps 1 to 100.
In existing LTE technology, a plurality of logic channels are by the multiplexing MCH channel of following mode: the corresponding TTI (Transmission Time Interval) of subframe, in a TTI, can send one or more transmission data blocks, the corresponding MAC PDU (medium access control layer protocol data cell) of each transmission data block.In a MAC PDU, can comprise a plurality of MAC SDU (service data unit), these MAC SDU can be from different logic channels, and different logic channels may comprise MTCH, MCCH, MSCH etc.After being serially connected in MAC PDU, these data from the Different Logic channel on physical channel, send together.In order to distinguish MACSDU from the Different Logic channel, carried identification information among the MAC PDU, concrete, the sign of logic channel is arranged, the positional informations of the data block of this logic channel in MAC PDU etc. are used for the data block of receiving terminal difference Different Logic channel.
To the dynamic multiplexing of MBMS business, a lot of different dispatching methods are arranged, as dispatching according to conditions such as QoS of survice characteristic, service priority, professional buffer data volumes.
For example: in a dispatching cycle, the MTCH continuous transmission of data of a MBMS business in other words, that is to say, the MBSFN sub-frame resources that takies the MCH channel that the data of a business are continuous, the whole transmission of business datum that needs to send in this dispatching cycle up to this business finishes, the more next professional data of transmission.
Simultaneously, the data of different business can send in same MBSFN subframe.That is to say that the transmission that is serially connected of business datum from different business can be arranged among the same MAC PDU.Wherein, professional sending order need be given receiving terminal by MCCH channel or other signaling.
At present, the send mode of schedule information has two kinds, a kind of method is to send by logic channel, carry as MSCH, the subframe number of configuration different business correspondence, the subframe numbers in the time of can being the subframe numbers that begins of data or ED or the subframe lengths of whole service data occupancy, or the combination of these information; Another kind method is control element territory of configuration in first MAC bag that begins each dispatching cycle, and this control element territory loaded information and MSCH go up the similar of carrying.
This dual mode all be with MCCH in service lists corresponding.In MCCH, comprise the current business information of transmitting, as ID, the session id of business; In MSCH or MAC dispatching zone, will adopt the corresponding order of acquiescence, dispose the transmission frame number of different business respectively; As the corresponding frame number of the corresponding frame number of first professional corresponding frame number 1, second business 2, the 3rd business 2, the 4th the corresponding frame number 3 of business, or the like.If certain business does not have data to dispatch, then can fill a particular value in this dispatching cycle.
But, do not consider in the prior art that because some business may repeatedly be dispatched, and this scene is not supported in the configuration of present schedule information owing to different traffic performance requirements in a dispatching cycle; Perhaps, will cause signaling traffic load heavier according to existing method configuration.
In addition, for the MCCH channel, think that at present it repeats the transmission cycle more than or equal to dispatching cycle, if in certain dispatching cycle, need to transmit MCCH, just when begin this dispatching cycle, transmission MCCH (being arranged in MAC SDU bag) information is transmitted MSCH (being arranged in MAC SDU bag) and MTCH (being arranged in MAC SDU bag) afterwards more earlier; Another kind of mode is transmission MCCH (being arranged in a MAC SDU bag) information earlier, afterwards transmitting scheduling information (being arranged in the MAC Control Element of MAC bag) and MTCH (being arranged in MAC SDU wraps) again.
Present way can not be supported the repeat its transmission cycle of MCCH is arranged to situation less than dispatching cycle.
