Description
Technical field
The present invention relates to the communications field, specifically, relate to a kind of multimedia broadcast-multicast service (Multimedia Broadcast Multicast Services, referred to as MBMS) the shaping preprocess method of Business Stream and broadcast multicast service center (Broadcast MulticastService Center, referred to as BM-SC).
Background technology
In order to effectively utilize mobile network resource, third generation partner program (3rdGeneration Partnership Project, referred to as 3GPP) propose MBMS, this business transmits 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, therefore, multiple abundant video, audio frequency and multimedia service can be provided, complied with the trend of following Mobile data development, the development for 3G provides better business prospect.
In Long Term Evolution (Long-Term Evolution, referred to as LTE), introduce Business Stream shaping (flow shaping) function.This function is used for the smoothing process of data burst to too concentrating, and to ensure that the business datum sent from BM-SC meets the requirement eating dishes without rice or wine to process, prevents because data volume too much causes the problem eating dishes without rice or wine to send.This function carries out work according to one or several conditions following: data volume, the multiplexing relation of the allocation of radio resources situation of Access Network side, the Radio Resource behaviour in service of Access Network side, arrival, whether be in same MBSFN district.
In LTE, MBMS can adopt multicasting mode work, be called single frequency network multicast broadcast (Multicast/Broadcast over Single Frequency Network, referred to as MBSFN) sending mode, adopt the MBMS that multicasting mode occurs, also referred to as MBSFN business, identical modulating-coding form can be adopted in multiple community, and adopting identical physical resource to send identical content, the feature of MBSFN multiple cell transmission comprises: transmit in the inter-sync of MBSFN region; Support that multiple cell MBMS transmission merges; Logical Traffic Channels (Multicast traffic Channel, referred to as MTCH) and multicast control channel (Multicast Control Channel, referred to as MCCH) be mapped on MCH transmission channel under point-to-multipoint (p-T-m) pattern; MBSFN retaining zone, MBSNF region is by the semi-static configuration of Operation and Maintenance.
At present, 3GPP specifies that a MBMS only has a synchronous protocol entity (SYNC Entity), even if BM-SC is connected to multiple RAN, for some MBMS, BM-SC still carries out unifying process.Such as, as shown in Figure 1, business A exists in RAN1, RAN2, RAN3 tri-wireless networks, a MBMS only has a synchronous protocol entity, that is, the packet of a MBMS only may stamp a timestamp, can not stamp different timestamps to same business data packet.
In fact, the situations such as the Radio Resource situation in RAN1, RAN2, RAN3 tri-wireless networks, the business datum amount of arrival and multiplexing relation may be all different, such as, that in RAN1, possibility is multiplexing is business A and business C, multiplexing in RAN2 is business A, business B and business C, and multiplexing in RAN3 is business A, business B and business D, this just requires that BM-SC should carry out different flow shaping process according to the respective situation of three wireless networks.And in existing 3GPP, because a business only has a synchronous protocol entity, unified flow shaping process can only be carried out on BM-SC, above-mentioned situation cannot be met.
Therefore, a synchronous protocol entity is only had to cause at multiple service area (such as a business in correlation technique, when RAN) using this business, the problem of flowshaping process cannot be carried out respectively, not yet propose effective solution at present.
