Embodiment 4
The embodiment of the present invention additionally provides a kind of multimedia broadcast multi-broadcasting business acquisition methods, and this method is the processing of UE sides corresponding with the method for embodiment 1, wherein explanation is not repeated in content same as Example 1.Fig. 7 is the flow chart of this method, refer to Fig. 7, and this method includes：
Step 701:User equipment receives the transmission means configured information that base station is sent；
Wherein, base station can be by way of broadcast or multicast to the above-mentioned transmission means configured information of UE transmissions, to indicate the transmission means of MBMS used in UE current areas.The content and bearing mode that the transmission means configured information is included are elaborated in embodiment 1, and its content is incorporated in this, will not be repeated here.
Step 702:The user equipment determines MBMS transmission means according to the transmission means configured information；Wherein, by the transmission means configured information, UE can determine the MBMS of current area transmission means.For example, if the transmission means configured information is included in system message or included in the message of multimedia control channel (MCCH) signaling, and the transmission means configured information is comprising MBMS service identifier or comprising MBMS task identifiers and transmission means designator and the transmission means designator is designated as mixed transport mode, then the user equipment determines that MBMS transmission means is mixed transport mode；If on the contrary, the transmission means configured information is included in system message or included in multimedia control channel（MCCH) in the message of signaling, but the transmission means configured information is not comprising MBMS service identifier or comprising MBMS service identifier and transmission means designator but the transmission means designator is designated as unicast transmission mode, then the user equipment determines that MBMS transmission means is unicast transmission mode.
Again for example, if the transmission means configured information is included in the PMCH configuration information elements of multimedia control channel (MCCH) signaling, and the transmission means configured information includes MBMS service identifier, and do not include the corresponding schedule information of MBMS business, then the user equipment determines that MBMS transmission means is mixed transport mode；If on the contrary, the transmission means configured information is included in multimedia control channel（MCCH) the PMCH configuration informations of signaling
In member, but the transmission means configured information not only comprising MBMS service identifier but also includes the corresponding schedule information of MBMS, then the user equipment determines that MBMS transmission means is broadcast multi-broadcasting transmission means.
Step 703:The user equipment obtains multimedia broadcast multi-broadcasting business according to the MBMS of determination transmission means.
Wherein, after MBMS transmission means is determined, UE can initiate corresponding MBMS request flows to obtain MBMS.
For example, if it is confirmed that MBMS transmission means is hybrid mode, then UE can initiate MBMS transmission requests to eNB, and eNB knows that UE is interested in the MBMS according to UE request, then eNB issues relevant configuration information to UE and starts to send MBMS data to the UE.In addition, if UE is in idle condition before MBMS request is initiated to eNB, then also connection status is gone to from idle condition including UE before this procedure.
For another example if it is confirmed that MBMS transmission means is mode of unicast, then UE can send MBMS transmission request message to core-network side entity, corresponding EPS carryings are set up, and MBMS data is received from EPS carryings.Similar, if UE is in idle condition before MBMS requests are initiated to core net, also go to connection status from idle condition including UE before this procedure.
For another example if it is confirmed that the transmission means of MBMS is broadcast multi-broadcasting mode, then UE receives MTCH configuration information, and receives MBMS data in the MBSFN sub-frame of distribution by MTCH.
Fig. 8 is the interaction schematic diagram of UE and network side entity, as shown in figure 8, the interaction comprises the following steps：
Step 801:ENB sends transmission means configured information by way of broadcast or multicast to UE, to indicate MBMS service transmission mode used in current area.
Wherein, the content and bearing mode of transmission means configured information are as it was previously stated, will not be repeated here.
