Description
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of at Long Term Evolution (LTE, LongTermEvolution) in system, the conversion method of multimedia broadcast multi-broadcasting business (MBMS, MultimediaBroadcastMulticastService) transmission means and system.
Background technology
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rdGenerationPartnershipProject) propose MBMS, namely a data source is provided to send the point-to-multipoint service of data to multiple user in a mobile network, MBMS achieves network resources locating, improve the utilance of Internet resources, especially valuable air interface resource.The MBMS technology studied in the lte networks, is called the multimedia broadcast multi-broadcasting business (E-MBMS, EvolvedMBMS) of evolution.
In existing LTE technology, the logic channel of MBMS is Logical Traffic Channels (MTCH, MulticastTrafficChannel), and the session of the corresponding MBMS of each MTCH.Multiple MTCH channel can be mapped to same transmission channel, namely on Multicast Channel (MCH, MulticastChannel); One or more MCH is mapped to same Physical Multicast Channel (PMCH, PhysicalMulticastChannel), a PMCH is made up of one group of multimedia broadcasting Single Frequency Network (MBSFN, MultimediaBroadcastSingleFrequencyNetwork) subframe.
In existing LTE technology, introduce the concept of MBSFN region (MBSFNarea), in a MBSFN region, MBMS adopts MBSFN mode to send; In same MBSFN region, different communities adopts identical resource and content, and the duplicate physical signalling of the transmission of time synchronized, to realize the diversity reception gain of receiving terminal.Can configure one or more PMCH in a MBSFN region, a PMCH can carry one or more MCH; Preferably, a PMCH carries a MCH.In LTE system, if need notifying user equipment (UE, UserEquipment) certain MBMS will change, these changes can be session start (sessionstart), service bearer upgrades or session stops (sessionstop) etc., can first at Physical Downlink Control Channel (PDCCH, PhysicalDownlinkControlChannel) Downlink Control Information (DCI is sent on, DownlinkControlInformation) and MBMS wireless network temporary sign symbol (M-RNTI, MBMS-RadioNetworkTemporaryIdentifier), UE reads concrete MBMS Control Channel (MCCH, MulticastControlChannel) message further according to the relevant information in DCI, and this is called MCCH notice (notification) mechanism.
MCCH is multicast control channel, and MCCH carries the configuration information of each MCH/PMCH in a MBSFN region, comprises MBSFN sub-frame configuration, Modulation and Coding Scheme etc. that each PMCH configures.In prior art, MCCH and MBSFN region is one to one.
The configuration information of MCCH also bearer service, comprises the information such as the mark of business in MBSFN region, session identification, state, Logic Channel Identifier (LCID, LogicalChannelID).UE starts the data receiving this business after obtaining the specific configuration information of a business by reception MCCH on MTCH channel.The configuration information of MCCH is sent by the form of system message in Broadcast Control Channel (BCCH, BroadcastControlChannel); If there is multiple MCCH, then each MCCH corresponding group configuration information in broadcast.
After UE enters MBSFN community, UE, by reading the message of BCCH, MCCH, to obtain the configuration information of MBMS in Target cell, then receives the data of required business on MTCH.
LTE/ System Architecture Evolution (SAE, SystemArchitectureEvolution) the MBMS framework under as shown in Figure 1, comprise following network element: BroadCast MultiCast Service center (BM-SC, BroadcastandmulticastServiceCenter), MBMS gateway (MBMS-GW, MBMSGateway), multimedia broadcast multi-broadcasting business coordination function entity (MCE, MBMSCoordinationEntity), the Node B (eNB, EvolvedNodeB) of evolution.
Wherein, BM-SC belongs to operation layer network element, is the entrance of content provider, there is provided convergence and the transmission of business, the mandate (generation of key and transmission) of user, the foundation of MBMS carrying and initiation, the initiation etc. of session control, what can also realize between BM-SC and eNB is synchronous simultaneously.MBMS-GW, as the node of between BM-SC and eNB, is the IAD of network, the signaling that the responsible processes user data message of being correlated with is relevant with session.
For single MBMS, MCE is mainly used in the scheduling of business, namely selects suitable resource (comprising the parameter such as frequency, time), carries out MBSFN transmission; For multiple MBMS, MCE needs to coordinate its corresponding multiple MBSFN transmission, comprises the size in MBSFN region, the use etc. of Radio Resource, reasonably, efficiently can use resource.
As shown in Figure 1, the interface of above-mentioned logic entity is as follows:
M1: be the interface between MBMS-GW and eNB, belong to user face (UP, UserPlane) interface, adopts Internet protocol (IP, InternetProtocol) multicast transmission mode, transmits MBMS data.
M2: be the interface between MCE and eNB, belong to chain of command (CP, ControlPlane) interface, adopts point-to-point (PTP, PointToPoint) transmission means.
M3: be the interface between mobile management entity (MME, MobilityManagementEntity) and MCE, belong to CP interface, transmission session control signal, adopts point-to-point transmission means.
MBMS comprises multicasting mode and broadcast mode, because multicast and broadcast mode exist different in business demand, causes its operation flow also different.
Under MBMS broadcast mode, because broadcasting service sends information to all users in wireless network, therefore, each network node does not need to perform MBMS registration process.MBMS session start process is triggered when BM-SC is ready to send data; For the bearing resource in need of MBMS transmission data in session start procedure activation network.By this process, BM-SC is by the fast mobile terminal group of this MBMS bearer service mark (TMGI, TerminalMobileGroupIdentify), service quality (QoS, QualityofService), MBMS territory, estimate that the session attributes such as length of session parameter are supplied to relevant network node.After downstream node completes relevant work, BM-SC goes on the air transfer of data.Each node transmits broadcast data to UE by the carrying of setting up in session start process.
MBMS multicasting mode is more similar with the main business workflow of broadcast mode, all needs to carry out successively the process of service statement, session start, MBMS notice, data transmission and conversation end; The difference of the two is, multicasting mode also needs user to contract corresponding multicast group, carries out activation of service, and adds the moment of exiting with user according to user and produce corresponding charge information.
In LTE, MBMS has two kinds of bearing modes: broadcast mode and enhancement mode broadcast mode.Owing to there is no multicasting mode, therefore, eNB can not be known UE reception/or prepare to receive which MBMS.Strengthen broadcast between broadcast and multicast, cover the advantage of resource optimization in the simple and multicast of flow process in broadcast.When using MBMS to strengthen broadcast bearer, only need on the application layer by adding/departure process just can realize from UE to BM-SC registration/cancellation, without the need to carrying out Signalling exchange and information storage in bearer network network layers.Strengthen broadcast be to broadcast one optimization and expansion, such as: at Access Network, strengthen broadcast can not to do not receive user community send data.For the MBMS of enhancement mode, at configuration-system frame number (SFN, SystemFrameNumber) and Resources allocation time need to consider to receive the UE state of MBMS and quantity, so just need to receive/or the UE information for preparing to receive MBMS feed back.
Obtain the number of users having MBMS demand in each community to enable eNB, MBMS system introduces counting process (counting).Counting process, when referring to a MBMS session start, or carry out in process in session, eNB adds up the process of reception and reception MBMS number of users interested in community, and UE feedback information is reported network side, in order to be confirmed whether to adopt MBSFN transmission means.
If count results reaches default thresholding, then eNB uses MBSFN transmission mode, otherwise the different access probability value of use is repeated counting process by eNB, if the count results several times in counting process does not all reach default thresholding, then eNB needs to stop MBSFN transmission mode, can change PTP unicast transmission mode into.
In 3GPP version 10 (Release10), propose the demand of the MBSFN transmission realizing activation or the given MBMS of deexcitation according to UE accepting state.For certain MBMS, network side can adopt point-to-multipoint (PTM, PointToMultipoint) to transmit (as MBSFN), and PTP also can be adopted to transmit (as clean culture).When adopting PTP transmission means, when reception UE quantity exceedes certain thresholding, PTM transmission means can be adopted, to save Internet resources; Equally, when adopting PTM transmission, when receiving UE quantity lower than certain thresholding, PTP can be adopted to transmit.This is referred to as the MBSFN transmission of activation/deactivation MBMS.
To in the research and practice process of prior art, inventor finds that prior art exists following problem: the MBSFN transmission mode needing activation or the given MBMS of deexcitation according to UE feedback result, this MBMS can continue transmission by PTM or PTP transmission means, but how to select corresponding transmission path, do you how to determine bearing resource? these problems, all do not provide relevant solution in the prior art.
