Each data payload has different requirements for transmission real-time performance and urgency; in practical applications, there is such a problem: the transmission rate and bandwidth of long-distance wireless transmission are limited. Which transmission method should be selected for transmitting a certain type of data, or which data should be given priority for transmission? How to ensure the best real-time performance and transmit as much valid data as possible better and faster under the effective rate and bandwidth? Currently, there is no particularly suitable solution. For this reason, the present application proposes a method for intelligent allocation of data payloads in a long-distance wireless communication system. Summary of the Invention

[0003] Based on the technical problems existing in the background art, the present invention proposes a method for intelligent allocation of data payloads in a long-distance wireless communication system.
