Problems solved by technology

[0004] In the process of realizing the embodiment of the present invention, the inventor found that in the prior art, the differential control of the transmission of MBMS in each cell in the SFA is carried out by grading the MCCH. Multi-level operation, such as multi-level operation of channel mapping from logical channel to transport channel and from transport channel to physical channel for primary MCCH message and secondary MCCH message, so the implementation method is more complicated

Abstract

A method and apparatus for transferring and acquiring multimedia broadcast multicast service (MBMS) control information are provided, wherein a method for transferring MBMS control information includes: a plurality of cells in a single frequency network area (SFA) transmit, using the single frequency network (SFN) mode, the service index of each service supported by said SFA and the MBMS control information corresponding to the service index; within each cell of the SFA, the MBMS service index that a cell supports is unicast or cell broadcast, so that an User Equipment (UE) can acquire the index of services supported by the cell that the UE is currently in, and the UE can acquire, from the MBMS control information, the MBMS control information corresponding to the index of services supported by the cell that the UE is currently in. Embodiments of the invention not only ensure the diversity gain when an UE receives MBMS control information, but also enable, in a simple manner, differentiated control for MBMS transferring by a plurality of cells within a SFA.

Description

Technical field [0001] The invention relates to communication technology, in particular to a method and device for transmitting and acquiring control information of a multicast multicast service. Background technique [0002] Enhanced Multicast Multicast Service (Envolved Multimedia Broadcast Multicast Service, EMBMS for short) is a multicast multicast in the mobile communication network proposed by the 3rd Generation Mobile Communications Global Standardization Organization (3rd Generation Partnership Project, 3GPP) The evolution service of Multimedia Broadcast Mul ticas t Service (MBMS for short) supports the transmission of MBMS data on the air interface in a single frequency network (SFN) mode, that is, the SF N coverage area (Single Frequency Network). Multiple cells in the Area (SFA for short) simultaneously use the same time-frequency resource to transmit the same MBMS. User equipment (User Equipment, UE for short) performs air interface combination on the received MBMS d...
