Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MBMS control signaling is transmitted without a uniform standard, then transmission flexibility is maintained, but terminal signaling overhead increases and power saving is hampered
Solution Approach 1:
The patent introduces specific parameters (radioFrameAllocationPeriod and radioFrameAllocationOffset) to control the transmission timing of MBMS control signaling. By changing these parameters, the system can standardize when control signaling is transmitted, allowing terminals to predict and efficiently receive signaling without excessive overhead, while still maintaining flexibility through different parameter values.
2Device complexity
If MBMS control signaling is transmitted randomly, then network resource sharing is simplified, but terminal power consumption increases due to frequent monitoring
Solution Approach 1:
The patent implements periodic transmission of MBMS control signaling at fixed intervals determined by radioFrameAllocationPeriod. This periodic action allows terminals to enter sleep modes between transmissions and only wake up at expected signaling times, dramatically reducing power consumption while maintaining simple network resource management through regular scheduling.
3Ease of manufacture
If MBMS control signaling timing is not standardized, then configuration simplicity is maintained, but resource utilization efficiency decreases
Solution Approach 1:
The patent performs preliminary configuration of transmission timing parameters (radioFrameAllocationPeriod and radioFrameAllocationOffset) before actual MBMS control signaling transmission. This preliminary action establishes a standardized timing framework that improves resource utilization efficiency while maintaining configuration simplicity, as the parameters are set once and then enable efficient, predictable signaling transmission.

AI summary
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 signaling at a terminal at a low signaling overhead.
