20110305186 | Method and system for transmitting a multimedia broadcast multicast service control signaling - The present invention discloses a method for transmitting a Multimedia Broadcast Multicast Service (MBMS) control signaling, comprising: a network side sends the indication information of a radio frame and/or a sub-frame carrying an MBMS control channel to a terminal via a high-level signaling and sends an MBMS control signaling to the terminal via the radio frame and/or the sub-frame carrying an MBMS control channel; and the terminal acquires the radio frame and/or the sub-frame carrying an MBMS control channel through analysis according to the acquired indication information of the radio frame and/or the sub-frame and reads the MBMS control signaling from the radio frame and/or the sub-frame. The present invention further discloses a system for transmitting an MBMS control signaling, which realizes the configuration of an MBMS control channel at a system side, provides a method for the transmission of an MBMS control signaling, and eliminates the randomness in the transmission of an MBMS control signaling at a system side signaling and the reception of an MBMS control is signaling at a terminal at a low signaling overhead. | 2011-12-15 |
