Embodiment
For making purpose of the present invention, technical scheme and advantage clearer, referring to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Little three classes that have been distinguished on the base station, as shown in Figure 3.One class is the residential quarter that will carry out the MBMS transfer of data, first kind residential quarter as shown in Figure 3, and this class residential quarter belongs to the MBSFN zone, and frequency of utilization is identical.If UE is under this class residential quarter, UE can receive the system information block (SIB of this residential quarter, System Information Block) the point-to-multipoint control channel (MCCH of information and MBMS, MBMSpoint-to-multipoint Control Channel) information, this process is the same with the process of at present definition.One class residential quarter is the residential quarter that does not participate in the MBMS transfer of data, Equations of The Second Kind residential quarter as shown in Figure 3, this class residential quarter may be in the geographical position with first kind residential quarter fully/overlap, but use different frequencies, perhaps this class residential quarter is identical with the frequency of MBSFN zone use, but be configured to " reservation residential quarter ", perhaps this class residential quarter is identical with the frequency of MBSFN zone use, be not configured to the MBSFN zone, the UE that is in the Equations of The Second Kind residential quarter can receive the signal of first kind residential quarter, and UE can switch/and gravity treatment is on the frequency of MBMS transfer of data.On this class residential quarter, can switch on the frequency of MBMS transfer of data in order to guarantee UE, some information of UE need to be notified in the base station, and these information help UE to choose the residential quarter of MBMS transmission, and the information of notice comprises the frequency of MBMS transmission at least.Also has a class residential quarter, this class residential quarter does not participate in the MBMS transfer of data, also overlapping with not having on the geographical position, residential quarter of MBMS transmission data, the 3rd class residential quarter as shown in Figure 3, this class residential quarter does not need to provide information, UE can not switch/and gravity treatment is to the residential quarter that MBMS will transmit, because this class residential quarter is non-conterminous with the residential quarter that MBMS will transmit.
A kind of scheme provided by the invention is: MCE determines at which/which frequency on broadcasting MBMS professional, the base station determine which Cell Broadcast CB this/these frequencies.The flow chart of this scheme comprises as shown in Figure 4:
Step 401:MCE is according to the MBSFN retaining zone sign of the residential quarter of collecting, perhaps according to the configuration of OAM, determine MBMS which/which frequency is transmitted, and the frequency of informing base station MBMS transmission.
Step 402: message is received in the base station, and the base station determines the frequency in which Cell Broadcast CB MBMS transmission, and broadcasts these information to UE.The base station can determine the frequency of broadcasting MBMS transmission on all residential quarters, also can be at the part Cell Broadcast CB, such as only having the residential quarter of overlapping covering to transmit (that is: Equations of The Second Kind residential quarter) with the residential quarter of wanting the MBMS transmission data, perhaps both wanting the residential quarter broadcasting (that is: first kind residential quarter) of MBMS transmission data, also do not participating in the MBMS transfer of data, and with the residential quarter of wanting the MBMS transmission data broadcasting (that is: Equations of The Second Kind residential quarter) on the residential quarter of overlapping covering is being arranged.The interested UE of MBMS is known the frequency of MBMS transmission, can listen to the control information of the MBMS on these frequencies, obtain the control information of MBMS in these frequencies, and when the interested business of UE at first, UE can switch and listens to the MBMS business on this frequency.
Embodiment one has described when base station and MCE set up the M2 interface, and which frequency MCE informing base station MBMS will broadcast in, the frequency that will transmit of base station broadcast MBMS business then, as shown in Figure 5.Fig. 5 realizes the continuously schematic flow sheet of the method for transmission of MBMS among the embodiment of the invention one and three.In embodiment one, method shown in Figure 5 can may further comprise the steps:
Step 501: " M2 sets up request information to MCE in the base station transmission.Message comprises the information of residential quarter on the sign of base station and the base station, and the information of residential quarter comprises: the MBSFN area identification of the sign of residential quarter, residential quarter and the service area identification list of residential quarter.
Step 502:MCE sends " M2 sets up response " message to the base station.MCE receives that the M2 from a plurality of base stations sets up request message, and according to the MBSFN retaining zone that the residential quarter is supported, MCE determines MBMS will in which frequency, and the principle of selection can be large according to the scope which frequency is disposed, and perhaps configured by OAM.The MCE informing base station will on which frequency broadcasting MBMS professional.
" M2 sets up response " message comprises the configuration information of the MCE sign Broadcast Control Channel (BCCH, Broadcast Control Channel) relevant with MCCH.This configuration information is for a MBSFN zone.The particular content of this configuration information comprises: MBSFN area identification, Physical Downlink Control Channel (PDCCH, Physical Downlink Control Channel) length, repetition period, side-play amount, modulation period, sub-frame allocation information and cell information tabulation.Cell information comprises: cell ID and residential quarter are that the reservation residential quarter also is the mark of non-reservation residential quarter.
As mentioned above, MCE also will by " M2 sets up response " informing base station will which/which frequency on broadcasting MBMS professional.The form of notice can have several different methods.
First method, " M2 sets up response " comprise the frequency information of MBMS transmission.For example, message comprises F1, and F2 illustrates that MBMS will broadcast at F1 and F2, not it may be noted that specifically which business is broadcasted at F1.
Second method, " M2 sets up response " comprise the MBSFN area identification of MBMS transmission.The MBSFN area identification has been known the MBSFN area identification with frequency dependence, the base station just known will on which frequency the MBMS transmission data.For example, message comprises MBSFN Area-1, illustrates that MBMS will transmit on MBSFN Area-1.In " M2 sets up response " message, be configured MBMS area identification and cell identification list, be exactly the MBMS area identification of having given each cell allocation." M2 sets up response " if the MBSFN area identification of having indicated MBMS to transmit, the residential quarter just knows whether oneself to participate in the MBSFN transmission by oneself MBMS area identification and the MBMS MBSFN area identification that will transmit relatively.
