Problems solved by technology

[0010] Regardless of the above situations, since the prior art does not give a unified transmission specification for P-MCCH, S-MCCH or MCCH, the transmission on the system side will be very random
That is to say, the terminal needs to try to receive the above-mentioned MBMS control channel (including: P-MCCH, S-MCCH, MCCH) very frequently, which will also bring randomness to the reception of the terminal, resulting in a large signaling overhead, and also Not convenient for terminal power saving

Embodiment Construction

[0074] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0075] A transmission method of MBMS control signaling provided by the present invention, such as figure 2 As shown, it mainly includes the following steps:

[0076]Step 201, the network side sends the indication information of the radio frame and / or subframe carrying the MBMS control channel to the terminal through high-layer signaling, and sends the MBMS control signaling to the terminal through the radio frame and / or subframe carrying the MBMS control channel .

[0077] The network side of the present invention may be a base station (eNB), or a mobility management entity (MME, MobilityManagement Entity), or a gateway (Get-way), or an evolved packet system (EPS, EvolvedPacket System), or a coordinated multipoint entity (MCE, Multi-cell / Multicast CoordinationEntity), etc. The base station eNB is taken as an exam...

Abstract

The invention discloses a method for transmitting a multimedia broadcast multicast service (MBMS) control signaling. In the method, a network side transmits the indicating information of a wireless frame and / or subframe carrying an MBMS control channel to a terminal by a high-level signaling and transmits an MBMS control signaling to the terminal by the wireless frame and / or subframe carrying the MBMS control channel; and the terminal analyzes the wireless frame and / or subframe carrying the MBMS control channel according to the indicating information of the obtained wireless frame and / or subframe and reads the MBMS control signaling from the wireless frame and / or subframe. The invention also discloses a system for transmitting the MBMS control signaling. The invention solves the problem that a system side is configured with the MBMS control channel, provides the method for the transmission of the MBMS control signaling and eliminates the randomness for transmitting the MBMS control signaling at the system side and receiving the MBMS control signaling at the terminal with less signalingexpense.

Description

technical field [0001] The present invention relates to a broadcast transmission technology in a long-term evolution (LTE) system, in particular to a transmission method and system for multimedia broadcast multicast service (MBMS) control signaling. Background technique [0002] With the rapid development of the Internet, a large number of mobile data multimedia services and various high-bandwidth multimedia services have emerged, such as: video conferencing, TV broadcasting, video on demand, advertisements, online education, interactive games, etc., which meet the rising demands of mobile users. Business requirements also bring new business growth points for mobile operators. These mobile data multimedia services require multiple users to receive the same data at the same time. Compared with ordinary data services, they have the characteristics of large data volume, long duration, and delay sensitivity. [0003] In order to effectively utilize mobile network resources, the...
