Problems solved by technology

Adaptive emergency radio equipment is small in size, easy to transport and install, and simple to operate. It is more suitable for mobile communication. The disadvantage is that the frequency resources are limited, and it is greatly affected by terrain, landforms, and weather. At the same time, it is difficult to guarantee the communication quality.
[0011] At present, we have not established a complete emergency communication system, the development of rescue technology is relatively slow, and the rescue communication equipment is still relatively backward. For example, during the Sichuan earthquake rescue operation on

Abstract

The invention provides an emergency communication system based on a wireless cellular network and an Ad-hoc network. The emergency communication system comprises a network control terminal and a communication terminal which communicate with each other through an Ad-hoc network. The invention also provides an emergency communication method based on the wireless cellular network and the Ad-hoc network. The method comprises a conventional communication mode and an emergency communication mode. In the conventional communication mode, data is exchanged through a mobile cellular telephone network; and in the emergency communication mode, data is exchanged through the Ad-hoc network. The system is used flexibly and conveniently, communication of the Ad-hoc network with the outside can be kept in various sudden events, a complete wireless communication network is established quickly, dead zone is prevented and rescue effect is optimized.

Description

technical field [0001] The invention relates to an emergency communication method and a communication device, in particular to an emergency communication system and method based on a wireless cellular network and an Ad-hoc network. Background technique [0002] my country is a country prone to natural disasters, and natural disasters such as earthquakes, floods, and transit typhoons occur from time to time. Especially in recent years, major catastrophic events such as ice and snowstorms, severe earthquakes, severe floods, mudslides, and mining disasters have occurred frequently, causing huge losses to human life and property. At present, in response to similar emergencies in my country, emergency communication technologies mainly include the following types: [0003] Emergency communication by means of landline telephones [0004] Fixed telephone has the advantages of wide coverage and large audience. In general, fixed telephone networks are the network of choice for emer...
