<p>A method for transmitting MBMS data, comprising: content provider sending Session Start Request with information of MBMS service area to BM-SC; upon receiving the request, BM-SC sending the request with the information of MBMS service area to BSC/RNC via GGSN and SGSN ; upon receiving the request, BSC/RNC judging whether there is overlap between BSC/RNC own covering area and MBMS service area in the request; if not, rejecting the current request and terminating current procedure; otherwise, building corresponding Iu bearer plane, Iub bearer, radio bearer with base station corresponding to overlap area, and allocating corresponding transmission resources; then content provider transmitting MBMS service data of MBMS session through built bearer along bearer plane and using allocated resources. This method can improve efficiency of MBMS service data transmission, transmit different MBMS service data in different MBMS service areas, and make full use of bearer capabilities of the cells.</p> |
