For making purpose of the present invention, technical scheme and advantage clearer, the embodiment that develops simultaneously with reference to the accompanying drawings is described in further detail the present invention.
Referring to shown in Figure 1, the MBMS implementation method in the multi-carrier district provided by the invention mainly may further comprise the steps:
Step 101: in the adjacent multi-carrier district of MBMS network, to be carried on same MBMS business configuration on the SCCPCH on the identical time slot of same carrier, and be identical basic midamble code of all MBMS time slot configuration (basic midamble code) and scrambler (scrambling code);
Step 102: base station and terminal utilize the basic midamble code of configuration and scrambler to carry out the transmission and the reception of MBMS business respectively on the time slot of described carrier frequency.
That is to say that for some specific MBMS business, the position that it is carried is consistent in the adjacent multi-carrier district of MBMS network.Such as, referring to shown in Figure 2, be that the system that disposes at 1: 5 is an example with the configuration of time slot transfer point, all there are three carrier frequency F1, F2 and F3 in each sub-district, and the main carrier frequency of each neighbor cell is different, and wherein, the difference on each carrier time slot is filled the different MBMS business of expression.As seen from Figure 2, for a certain specific MBMS business, the carrier frequency that it is positioned in each sub-district is all identical with time slot, can be carried on the some of same carrier or certain the several time slot; For different MBMS business, they both can be carried on the different carrier frequency, also can be carried on the different time-gap of same carrier.
