Abstract

Abstract:

Aiming at the problems of single means, insufficient bandwidth and poor security of information transmission in emergency communication practice, this paper adopted the key technologies of 4G public network multi-channel aggregation transmission and multi-path transmission wireless communication based on IPSec VPN, and proposed multi-SIM cards wireless public network networking using security aggregation gateway to realize multi-path real-time transmission of data flow. The technology of low delay aggregation and security encryption is integrated, and the TCP acceleration program in the modem is transplanted to the satellite security module, which realizes the combination of satellite communication TCP acceleration and encryption technology, and completes the multi-path transmission of security satellite networking. This research adopts the layered design idea to provide a safe and reliable multi-path wireless channel for the new generation of emergency communication.

Key words: IPSec VPN, multi-channel aggregation, satellite communication, emergency communication
