Embodiment Construction

[0038] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0039] The wireless cellular phone and wireless local area network emergency communication method comprises the following steps:

[0040](1) Under normal circumstances, the communication system is in the normal communication mode (such as communication through optical cables, copper cables, microwaves, etc.). communication mode; if it is detected that the normal communication link failure is eliminated, the communication system will be switched back to the normal communication mode.

[0041] The fault detection method of the conventional communication uplink is as follows: the fault of the uplink communication link includes various situations such as communication information integrity, communication interruption, etc., if the communication system finds that the relevant signaling in the operation and maintenance link has a broken link alarm, Then it is judged th...

Abstract

The invention relates to an emergency communication method of a wireless cell phone and a wireless local area network and a communication device. The communication method comprises the following steps: (1) under normal condition, a communication system is in general communication mode, if the communication system detects that a general communication link fails, the communication system is switched into an emergency communication mode; if the communication system detects that the failures of the general communication link are eliminated, the communication system is switched back to the general communication mode; (2) under normal condition, the communication system is in general communication mode, if an authorized user starts the emergency communication mode, the communication system is switched into the emergency communication mode; if the authorized user closes the emergency communication mode, the communication system is switched back to the general communication mode; and (3) under normal condition, the communication system is powered by an external power supply, if the external power supply fails, the communication system is switched into a standby power supply; if the failures of the external power supply are eliminated, the communication system is switched back to the external power supply. The emergency communication method and the communication device solve the problem of communication between wireless users under emergency conditions.

Description

technical field [0001] The invention relates to a wireless communication method and a communication device, in particular to a wireless emergency communication method and a communication device. Background technique [0002] Earthquake is one of the most harmful natural disasters to human safety, and China is located between the circum-Pacific seismic belt and the Eurasian seismic belt, and is one of the countries with the strongest seismic activity and the most serious earthquake disasters in the world. China accounts for 7% of the world's land area. In the 20th century, 35% of the global continent's earthquakes with a magnitude of 7.0 or more occurred in China. Among the 1.2 million earthquake deaths in the 20th century, China accounted for 590,000, ranking first among all countries. According to the "National Earthquake Prevention and Disaster Reduction Plan (2006-2020)", most of mainland China is located in areas with earthquake intensity above VI; 50% of the country's l...
