Abstract
Abstract The present invention provides a service transmission method for MBMS, comprising: a core network initiates an MBMS service; having received a session start instruction of the MBMS service, the RNC selects the PTM mode or the PTP mode as a service bearer mode to bear the MBMS service for each cell that belongs to the RNC. The method of the invention makes it possible to directly adopt the PTM mode or the PTP mode to bear an MBMS service, skipping the complicated Counting process adopted by the prior art, reducing the complexity of the system, decreasing interaction of signaling of the air interface, and lowering power consumption of the UE.
