Abstract: Embodiments of the present disclosure provide a multicast service transmission method, including: a terminal receives from a first cell, configuration information corresponding to an MBMS, where the configuration information corresponding to the MBMS includes: a cell identity of at least one second cell; the terminal obtains configuration information of the second cell based on the cell identity of the second cell; and receives from the second cell, an MTCH based on the configuration information of the second cell. This resolves a problem that the terminal can receive in one cell, an MCCH and the MTCH corresponding to the MBMS, and achieves an effect that the terminal device can receive, from the first cell and the at least one second cell, a same multicast service by using a carrier aggregation technology.
