Abstract: The emergence of eSIM card is another evolution of SIM card, and it is also in line with the technical development direction and market demand of SIM card from large to small and from real to virtual. This paper aims to combine 5G communication technology to study the over-the-air programming and real-name authentication technology of eSIM, and proposes a new random access design for the long delay and rapid timing advance (TA) change characteristics of low-orbit satellite communication system. Moreover, this paper proposes a random access preamble structure based on polarity expansion and a new TA adjustment strategy based on downlink tracking. In addition, this paper designs a random access response data structure suitable for LEO satellite environment at the protocol layer, and builds a blockchain eSIM solution architecture design system based on 5G communication. Finally, this paper verifies the effectiveness of the technology proposed in this paper combined with experimental tests, thus providing a theoretical reference for subsequent related research on the popularisation of eSIM to user groups.
