Implementation method of emergency communication network based on 4G-LTE

Abstract

The invention discloses an implementation method of an emergency communication network based on 4G-LTE. The implementation method comprises the steps: a wireless local area network covering the emergency communication area is constructed, an intelligent terminal is connected with a command and control center through the wireless local area network, and the intelligent terminal is connected with the command and control center through the 4G network. The emergency network constructed by the method has better robustness when disasters occur, the network can maximize the contact between the affected region and the outside when other networks are down, and the user can connect directly to the Internet through Sim card traffic of the 4G network and can also access to the internet via the sink node router through the omnibearing WIFI network which is composed of multiple intelligent routers and covers the area of the community so as to realize the communication between the command center server client and the user of the emergency area APP and further reduce the loss of life and property caused by the disaster.

Description

technical field [0001] The invention relates to the technical field of emergency communication network applied to disaster prevention and mitigation, in particular to an implementation method of an emergency communication network based on 4G-LTE. Background technique [0002] In recent years, domestic earthquakes, fires, floods and other disasters have brought serious loss of life and property to people. Especially after the disaster, the fixed and mobile communication networks in the region have been greatly damaged, the communication between the outside world and the disaster area is interrupted, the information on the disaster situation is insufficient, and it is impossible to know the situation of some of the hardest-hit areas, which directly affects the rescue and relief work. carried out, resulting in significant loss of life and property. [0003] With the development of modern communication technology, how to apply remote sensing, geographic information system, navi...
