Abstract

The invention provides an emergency communication method and system based on Beidou satellite communication, and the method comprises the steps: receiving a text message sent by a user side, sending an ID of the user side, carrying out caching, compressing the text message and an ID of a user side of a receiver to generate Beidou message information, and sending the Beidou message information to multiple paths of Beidou message communication terminals; forwarding the Beidou message information to a Beidou message emergency forwarding server through a Beidou satellite; and receiving the Beidoumessage information, decompressing the Beidou message information to obtain a text message and a receiver user side ID, and sending the text message to a corresponding target receiver user side according to the receiver user side ID. According to the invention, based on the Beidou message as an information carrier, communication between the Beidou message and the short message is realized withoutrelying on mobile communication and Internet communication, an emergency communication means is provided for vast vast disaster victims, and the transmission of an emergency communication scheduling instruction, a rescue message and alarm information is further satisfied.

Description

Technical field [0001] This application relates to the field of satellite communication technology, and in particular to an emergency communication method and system based on Beidou satellite communication. Background technique [0002] The Beidou satellite navigation system is a global satellite positioning and communication system (BDS) developed by China. It is the third mature satellite navigation system after the US Global Positioning System (GPS) and Russia's GLONASS. It can provide high-precision, high-reliability positioning, navigation, and timing services for all kinds of users around the world, all weather and all day, and it has short message communication (Beidou communication) capabilities. [0003] When geological disasters and climate disasters occur, mobile communication networks and power supply networks are interrupted, or in areas without communication network coverage, the victims cannot get in touch with external parties and cannot pass on information for help...
