Abstract: Aiming at the problem of long delay response of online mobile teaching platform, a design method of online mobile teaching platform based on Android 5G environment is proposed. Firstly, the hardware of the online learning platform is designed, and the Android mobile terminal is taken as the hardware core. In the software part of the system, AIMD algorithm is used to reduce the transmission volume. By controlling the speed of multimedia data flow on the platform, the network congestion of the platform is alleviated. DB-KAD algorithm is used to select the optimised network delay parameters to meet the requirements of multimedia data transmission. The performance test results show that the maximum response delay of this method is 0.07 s, the maximum buffer delay of video is 1.4 s, the number of video pauses varies in the range of 0-1.0, and the response delay requirement of online mobile teaching platform.

Keywords: 5G environment; Android system; online mobile teaching.
