    • The present invention provides a method of receiving a multimedia broadcast/multicast service in a user equipment of a wireless communication system based on MBSFN transmission and a method of assisting the user equipment to receive the service in the corresponding base station; wherein the user equipment receives a transport block from the base station in a predefined period; and then judges whether a notification indicator in the transport block is activated, if so, then judges whether a service identification of a multimedia broadcast/multicast service subscribed to by the user equipment is included in a transport block including a control signaling in the transport block, if so, then receives the multimedia broadcast/multicast service. By implementing the present invention, a user terminal in IDLE mode only needs a predefined period such as a DRX period to wake up to receive the notification indicator to judge whether a new service will start without waking up at extra time.
