Abstract: The present disclosure provides a method, a system, and an apparatus for transmitting group communication service data. In the present disclosure, the LTE uses a multimedia broadcast and multicast service (MBMS) to transmit group communication system enabler (GCSE) service data, a multi-cell/multicast coordination entity (MCE) knows whether a multimedia broadcast single frequency network (MBSFN) transmission mode or a single cell multicast transmission mode is used to transmit the GCSE service data. Whether the MBSFN transmission mode or the single cell multicast transmission mode is used to transmit the GCSE service data is determined based on UE capability information and UE location information. When the single cell multicast transmission mode is used, the MCE instructs an eNodeB (eNB) to use the single cell multicast transmission mode to transmit the GCSE service data. The present disclosure saves LTE air interface resources.
