Abstract
The invention discloses a method for realizing synchronous resource allocation of a multimedia broadcast and multicast service, wherein, a plurality of radio network controllers which need to transmit data of the multimedia broadcast and multicast service synchronously are allocated with the same allocation information of the multimedia broadcast and multicast service; and a plurality of radio network controllers allocate physical channel resources and transmission channel resources according to the allocation information of the multimedia broadcast and multicast service. By using the method, a plurality of RNCs which need to transmit MBMS synchronously can allocate the same physical channel resource for a same MBMS to carry out the allocation in various protocol layers of the same RLC, PDCP, and the like, thus being capable of ensuring synchronous transmission of MBMS among RNCs.
Description
Technical field
The present invention relates to wireless communication technology field, particularly, relate to multimedia broadcast-multicast service (Multimedia Broadcast/Multicast Service abbreviates MBMS as) the synchronous implementation method of resource allocation.
Background technology
Along with the Internet rapid network development, people no longer content just to phone and messaging service to the demand of mobile communication, meanwhile, a large amount of multimedia services also occurred.For some applied business wherein, a plurality of users can receive identical data simultaneously, as video request program, television broadcasting, video conference, online education, interactive game etc.
In order to realize utilizing most effectively mobile network resource, MBMS (Multimedia Broadcast/Multicast Service, multimedia broadcast/multi broadcast service) technology has appearred.MBMS is meant that a data source sends the point-to-multipoint service of data to a plurality of users, and it has realized that Internet resources share, and comprises especially sharing of interface-free resources of mobile core network and access network resource.
3GPP (3rd Generation Partnership Project, third generation partner program) Ding Yi MBMS can not only realize the classes of messages multicast and the broadcasting of plain text low rate, and can also realize the multimedia service multicast and the broadcasting of two-forty, this has complied with the trend of following mobile data development undoubtedly.
As the technology that improves the professional availability of frequency spectrum of MBMS, single frequency network (SingleFrequency Network abbreviates SFN as) or Chip merge (chip-level merging) wireless signal that all adjacent base station synchronized transmissions of specification requirement are identical.
Under the SFN pattern, subscriber equipment (User Equipment, abbreviate UE as) signal from different base station can be considered as multipath signal, make public physic channel transmit broadcasting service and obtain bigger signal gain, thereby improved QoS (Quality of Service, the service quality) performance of MBMS business.But the introducing of this technology has also brought new problem, that is, if be considered as multipath from the signal of different base station by UE, then require each footpath data must keep synchronized transmission.Under the Chip merging patterns, UE receives the service signal that different base station sends simultaneously, and realizes merging at chip-level by the multi-plot joint detection technique.The MBMS service signal that this different districts that all requires UE to receive sends all is the same at same time slot.
After 3GPP introduces MBMS, variation has taken place in the protocol stack of user's face, radio network controller (Radio Network Controller, abbreviate RNC as) can be when the MBMS service carrier is set up according to core net coverage (Service Area, abbreviate SA as) tabulation, be made into the cell set mode with affiliated cell set and set up shared PDCP (the Packet Data Convergence Protocol in a plurality of sub-districts, PDCP) and RLC (Radio Link Control, Radio Link control) entity, MAC-m (Medium Access Control for MBMS is separately used in each sub-district, the medium access control of MBMS) and FP separately (Frame Protocol, Frame Protocol).
The MBMS business is the service towards the whole network, and same MBMS business may be based upon on the different RNCs.Like this, the UE receiving gain is improved in order to utilize SFN or Chip folding in sub-district between different RNCs, need the MBMS business identical signal of eating dishes without rice or wine with the sub-district synchronized transmission of adjacent R NC, otherwise, belong to that signal can cause co-channel interference between the neighbor cell of different RNCs, perhaps UE can not get receiving gain.
Because the mode of different RNCs processing service data and parameter is different, and consider that network congestion causes the delay of the business datum that RNC receives even the possibility of losing, the minizone that guarantees to belong to different RNCs can the identical signal of eating dishes without rice or wine of synchronized transmission, just needs harmonious assurance the between RNC.
As shown in Figure 1, in a kind of method that realizes MBMS service synchronization between RNC by the Iur interface between RNC, the RNC that needs synchronized transmission MBMS business is divided into main RNC and from RNC, wherein, main RNC handles the MBMS business datum from function.In addition, as shown in Figure 1, be connected by the Iu interface between core net and SRNC or the DRNC, a SRNC can be connected with a plurality of DRCN, and also connects by the Iur interface between the DRNC.
But for how realizing making that different RNC keeps resource allocation synchronous to same MBMS is professional in the retaining zone, above-mentioned method does not provide solution.Above-mentioned resource allocation specifically comprises: physical channel distributes, TFS Transport Format Set (Transportformat Set, abbreviate TFS as) business configuration, transport format combination set (TransportFormat Combination Set, abbreviate TFCS as) business configuration, MBMS service identification (MBMS-ID) configuration, TDM (Time Division Multiplexing, time division multiplexing) business configuration etc.
Yet, if can not guarantee the synchronous configuration of above-mentioned each RNC, can cause the channel allocation difference between the synchronous RNC of needs, thereby can not guarantee that the MBMS business realizes synchronously between RNC.
