Abstract

With the launch of Huawei's mobile phone terminal supporting mobile phone direct connection satellite, mobile phone direct connection satellite has become an important hotspot and attention direction of satellite mobile communication. The essence of mobile phone direct connection satellite is a satellite communication system that communicates business between mobile phones through satellite relay. This paper expounds on the connotation of the mobile phone direct connection satellite, the three directions of the technical development route and their respective characteristics. Aiming at the dedicated chip integration mode, it designs the system architecture of the mobile phone directly connecting satellite in detail, and designs the hardware and software of different processing units in detail. The scheme is applied to a variety of mobile phones.

Keywords
