摘要：

针对应急通信中信息传输手段单一、带宽不足和安全性差等问题,文章采用基于IPSec VPN的4G公网多路聚合传输和多路径传输无线通信关键技术,利用安全聚合网关的多SIM卡无线公网组网,实现了数据流多路径实时传输、低延时聚合和安全加密的技术融合。将调制解调器中的TCP加速程序移植到卫星安全模块中,实现了卫星通信TCP加速和加密技术的结合,完成安全卫星组网多路径传输。文章采用分层设计思想,可以为新一代应急通信提供安全可靠的多路径无线信道。

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
