Description
Technical field
The present invention relates to mobile communication technology field, particularly relate to receiving/transmission method, device and the system of a kind of MCCH.
Background technology
In 3G (Third Generation) Moblie technical field, LTE (Long Term Evolution, Long Term Evolution) R9 (Release 9, the 9th version) system introduced MBMS (Multimedia Broadcast MulticastService, multimedia broadcast multi-broadcasting business) mechanism, by MCCH (Multicast Control Channel, multicast control channel) control information of MBMS transmission, and by BCCH (Broadcast ControlChannel, Broadcast Control Channel) transmission MCCH MCS (Modulation and Coding Scheme, modulating-coding form) information.If UE is (User Equipment, subscriber equipment) to transmit the MCS using not identical for MCS and the current MCCH of the MCCH that receives by BCCH, will cause MCCH to receive mistake, further cause UE cannot normally receive MBMS business, affect user and experience.
As shown in Figure 1, for the MBMS configuration diagram in LTE R9 system, wherein, M3 interface is MCE (MBMS Coordination Entity, MBMS is coordinated) and MME (Mobility Management Entity, Mobility Management Entity) between interface, for this interface definition corresponding application function, to carry out EPS (Evolved Packet System, Evolved Packet System) MBMS session control signaling mutual of carrying grade, relevant session control process comprises MBMSSession Start (session starts) and MBMS Session Stop (session stops), the signalling of this interface uses SCTP (Stream Control Transmission Protocol, SCTP), the signalling of this interface is point-to-point carrying out.M2 interface is MCE and eNB (Evolved Node B, evolved Node B) between logic interfacing, for this interface definition corresponding application function, to transmit many cell transmission pattern eNB required radio configuration parameters and session control signaling, the signalling of this interface also uses SCTP, the signalling of this interface is also point-to-point mode, the transmission path of chain of command information is from BM-SC (Broadcast Multicast Service Center, BroadCast MultiCast Service center) to MME, arrive again MCE, then to eNB.M1 interface is MBMS GW (Gate Way, gateway) and eNB between logic interfacing, this interface is a pure interface in the user plane, on interface, do not define chain of command application function, the transmission of pointing to the user grouping of He Duo community, single community is based on IP (InternetProtocol, Internet protocol) PTM (the Point To Multi-Point of multicast, point-to-multipoint) transmission, the bang path of user face data is: from BM-SC to MBMS GW, then to eNB.
The interrelated logic channel of MBMS comprises BCCH, MCCH and MTCH, and wherein, BCCH is used for network to UE broadcast system information; MCCH is the down channel of a PTM, be used for network to the relevant control information of UE MBMS transmission, a MCCH can be corresponding to one or more MTCH (Multicast Traffic Channel, multicast service channel), only have the UE that can receive MBMS business just can use MCCH, UE can be notified by system broadcasts by the MCS of MCCH, amendment cycle and repetition period in base station, the amendment cycle is generally N times of repetition period, within an amendment cycle, the MCCH information that all repetition periods send is the same, to ensure the reliable reception of MCCH.MTCH is a point-to-multipoint down channel, be used for network to UE transferring MBMS service data, only have the UE that can receive MBMS business just can use MTCH, the information of MTCH is to be indicated by its corresponding MCCH, network utilisation BCCH indicates MCCH to UE, recycling MCCH indicates MTCH to UE, thereby reaches the object that makes UE be received in the MBMS business of the upper carrying of MTCH.
In current LTE system, except ETWS (Earthquake and Tsunami Warning System, earthquake and tsunami warning system) outside information, the change of system information can only occur in specific radio frames, definite by the amendment cycle (modification period), wherein, the amendment periodic regime of BCCH is 640ms～40.96s.Within an amendment cycle, system information may send repeatedly, and the system information content repeatedly sending is identical.System information can only change after the border in amendment cycle, and the boundary definition of amendment period m is SFN mod m=0; Wherein, SFN is System Frame Number, and m is amendment cycle (unit is radio frames).In the time that network needs altering system information (all or part of system information), first need to the instruction of terminal transmitting system information-change, notification terminal changes the system information occurring, and notification procedure may need to continue an amendment cycle.In the next one amendment cycle, network sends the system information after upgrading, and as shown in Figure 2, wherein, different colors represent the system information of different cycles.
Receiving that system information changes after instruction, terminal reads the system information after renewal in the beginning in next one amendment cycle immediately.Before terminal is obtained new system, terminal continues to use old system information.Network uses paging information to the terminal transmitting system information-change instruction in RRC_IDLE and RRC_CONNECTED state.If terminal has been received the paging information that comprises " systemInfoModification ", can know that system information can revise the boundary in cycle at the next one and change.System information changes instruction and only can notification terminal system information will change, and can not indicate the system information changing to terminal.In addition, if variation has occurred system information, the ValueTag in SIB (System Information Block, system information block) 1 also can change, and UE also can judge whether system information renewal by reading ValueTag.
Terminal can determine that whether the system information of depositing is effective by the following method: in the situation that not receiving systemInfoModification instruction, terminal need to be within an amendment cycle, at least read paging information modificationPeriodCoeff time, to finding systemInfoModification instruction.If do not read paging information, terminal thinks that system information will can not change within the next one amendment cycle.If terminal reads the paging information that comprises systemInfoModification instruction, just think that system information will change in the next one is revised the cycle.
In LTE R9, specify at present, if MBMS is special SIB, the SIB (SIB13) that carries MBMS information changes, and can cause system information to change, and affects the ValueTag in systemInfoModification instruction and the SIB1 in beep-page message.Because the MCS of MCCH carries by SIB13, therefore, in the time that the MCS of MCCH changes, can cause SIB13 to change, and then cause system information to change, the UE next BCCH amendment cycle after system information Notification of Changes of need to receiving is read SIB13 again, then according to the MCS of the MCCH in SIB13, MCCH is received.
LTE R9 is divided into two kinds of situations for the reception of MCCH: for the UE that does not receive MBMS business, carry out the reception of MCCH by monitoring MBMS Notification (notice) information; For the UE that receives MBMS business, periodically monitor MCCH.In the time having the SessionStart (session starts) of MBMS business, network can send Notification information to UE, notify UE to have new MBMS service conversation to start, UE, after receiving Notification information, reads MCCH by the amendment cycle at next MCCH, obtain the specifying information of Session, if UE is interested in this MBMS business, according to the content of MCCH, read corresponding MTCH, receive this MBMS business, as shown in Figure 3.
For the UE that does not receive MBMS, if this UE receives Notification information, will read MCCH in the next one amendment cycle; If this UE does not receive Notification information, will continue to monitor Notification subframe, and can not read MCCH.For the UE that receives MBMS business, each MCCH amendment cycle needs to read MCCH information, does not need to monitor Notification subframe.
There is amendment cycle and repetition period in MCCH, MCCH Information invariability within the amendment cycle, and carry out repetition with the repetition period.UE can receive repeatedly identical MCCH information within the amendment cycle, just receives once correctly solution and reads the information that MCCH carries, as shown in Figure 4 as long as correct.The amendment cycle of MCCH is consistent in MBSFN (Multicast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) region, and the amendment cycle of BCCH is community independent maintenance.The information such as MCS, amendment cycle and the repetition period of MCCH, be all to be generated by MCE, then sends to eNB, and eNB, using a part for above-mentioned information content in SIB13, carries out system information broadcast in Zhe community.And MCCH generates and sends eNB by MCE, this partial information is sent to the UE in community by eNB.In addition, in LTE agreement, also specify, before UE receives the system information of renewal, the system information before still using; After UE receives the system information of renewal, can apply immediately, and needn't by the time receive all system informations.
Inventor is realizing in process of the present invention, and at least there are the following problems to find prior art:
Because the relation in BCCH amendment cycle and MCCH amendment cycle is not yet definite, the problem that uses prior art can exist MCCH mistake to receive.Taking the scene shown in Fig. 5 as example, wherein, the amendment cycle of BCCH is 20.48s, and the amendment cycle of MCCH is 10.24s.In the time that the MCS of MCCH changes, UE can upgrade system information, suppose that UE obtains the new MCS of the MCCH in new system information in the T1 moment, UE will utilize new MCS to receive MCCH in the T2 moment, because the MCS of MCCH will change in the T3 moment, therefore in the T2 moment, what MCCH used remains old MCS, and UE receives MCCH in the T2 moment according to new MCS, can cause UE cannot correctly receive the situation of MCCH, and then cause receiving MBMS business, affect user and experience.
