Description
Technical field
The present invention relates to the communications field, and especially, relate to the wireless resource coordination method of multimedia broadcast multi-broadcasting business in the communication system (MBMS).
Background technology
The MBMS business is the 3rd generation partner project (Third Generation PartnershipProject, 3GPP) a kind of point-to-multipoint service that is sent data in the mobile network by a data source to a plurality of users of Ti Chuing.By utilizing the MBMS technology, a plurality of users can receive identical business information simultaneously, for example, and weather forecast, news, advertisement, information etc.Therefore, the proposition of MBMS can realize that mobile core network and access network resources share, and improves utilization rate of network resource, has especially improved the utilance of valuable interface-free resources.
Show long evolving system (Long TermEvolution, the block diagram of MBMS operation system logical construction example LTE) of mobile communication system as Fig. 1.
As shown in Figure 1, broadcast multicast service center (BM-SC) is the mobile network functional entity, and it is content provider's a inlet, be used for authorizing and initiating the MBMS bearer service at mobile network, and plan transmits the MBMS content to schedule; (Node B of evolution (Evolved Node B, eNB)) and (subscriber equipment (UserEquipment is called for short UE)), also need to increase MBMS correlation function and process for existing network functional entity;
The function of broadcasting multicast service gateway entity (MBMS-GW) comprises the user face data processing, and the transmission and the processing of possible signaling plane data; MBMS-GW is the anchor point between broadcast multicast service center (BM-SC) and the eNodeB;
Multimedia broadcasting and multicast coordination entity (MBMS Coordination Entity, abbreviation MCE) major function is that the resource of coordinating the involved different MBMS business of this MCE is used, so that form unifrequency network (the MBMS Single Frequency Network of suitable multimedia broadcast multicast services, be called for short MBSFN), reach the purpose that reduces to disturb, improve resource utilization;
(Evolved NodeB eNB) is follow-on base station to the Node B of evolution, and higher up-downgoing speed, lower transmission delay and reliable more wireless transmission can be provided.
In the Long Term Evolution of mobile communication system, introduced the unifrequency network concept of multimedia broadcast multicast services.Unifrequency network (MBSFN) notion according to multimedia broadcast multicast services, MBSFN may comprise a plurality of continuous sub-districts, if the professional MBSFN mode that adopts of MBMS sends, then on all sub-districts that MBSFN comprises, adopt identical resource (promptly, adopt parameters such as identical frequency and time) send this MBMS business, make UE to merge to received signal, thereby improve reception.Simultaneously, if there are a plurality of MBMS business on same sub-district, then they can not use identical MBSFN, in order to avoid signal disturbs each other.
According to present MBSFN definition, MBSFN can be a fixing zone, this zone is pre-set before its corresponding M BMS begins to send, its zone is a plurality of continuous sub-districts, although and user that after this should business may change to some extent, but this MBSFN zone does not change with number of users, and this zone is fixed on the geographic area.In addition, MBSFN also can be a dynamic zone.In this case, this zone may change along with the variation of number of users, for example, in case there is not the user to receive corresponding M BMS business in the sub-district that certain MBSFN comprises, then this sub-district can no longer belong to this MBSFN, corresponding resource is released in this sub-district, so change has taken place in the MBSFN zone.
According to the network standard of existing 3GPP, when needs are set up a MBSFN, need to distribute corresponding adequate resources.But the present method that does not also have corresponding M BMS resource coordination in the 3GPP agreement promptly, does not also have to allow MCE judge the operable method of which resource according to current resource operating position.
On the ordinary meaning, all eNB that the MCE linchpin belongs to need to report its resource behaviour in service, in this case, if the eNB quantity that MCE connects is too many, will directly cause the uplink congestion of MCE, the processing time is long, influence user's susceptibility, and workload is huge for MCE.
Therefore, it is necessary can carrying out coordination technical scheme to the MBMS resource.
