Vehicle-mounted communication system

Abstract

The invention discloses a vehicle-mounted communication system which comprises a satellite, a satellite main station, a signal receiving device of a communication vehicle, an MSC (Mobile Switching Center) and a BSC (Base Station Controller), wherein the satellite main station receives a satellite signal; the MSC and BSC are connected with the satellite main station through ground optical cables; the communication vehicle is connected with a ground receiving device through a microwave wireless Ethernet bridge; a vehicle-mounted satellite antenna at the ku frequency band of the communication vehicle receives the satellite signal. The vehicle-mounted communication system has the advantages of high arrangement speed and capacity of improving the emergency processing property; an effect that can not be underestimated is achieved on quick, efficient and ordered operation of emergency communication commanding and dispatching.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to the field of communication technology. Background technique [0002] When sudden public events (such as rain and snow, earthquakes, floods, etc.) occur, the public communication network may be damaged, and there may be excessive traffic locally on the network, which will cause the communication network's carrying capacity to decrease, thereby resulting in a decrease in emergency response capabilities. The vehicle emergency communication system is an important part of the emergency communication system. It can quickly provide effective emergency communication support after the mobile communication base station is paralyzed or the network is congested, and strengthen the party, government, military and other important departments when public emergencies occur. Communication capabilities to ensure emergency communication command and dispatch for sudden disast...
