Distributed transmission method for ubiquitous-mobile-network-based emergency communication system

Abstract

The invention relates to a distributed transmission method for a ubiquitous-mobile-network-based emergency communication system. In the method, a local emergency command center performs scheduling according to resource sensing information transmitted back by a plurality of emergency communication terminals accessing a ubiquitous network on an emergency communication scene, and the emergency communication terminals are aggregated at the remote emergency command center after transmitting own data packets according to scheduling information to realize the distributed transmission of an emergency communication scene video stream. By the method, the high-speed and real-time information transmission of the emergency communication scene can be ensured under the conditions of large commercial network user number and heavy load on the emergency communication scene.

Description

technical field [0001] The present invention mainly relates to the field of resource management and scheduling in the ubiquitous mobile communication network, and specifically relates to a distributed transmission method of the ubiquitous mobile communication system based on the existing 3G and Wi-Fi technologies. Background technique [0002] Emergency communication is a special communication mechanism to deal with sudden large-scale natural disasters and public emergencies. Emergency communication usually adopts unconventional, multiple Combination of communication means to restore communication capabilities. At present, communication operators usually adopt a dedicated emergency communication system with emergency communication vehicles as the main body, combined with satellite channels and microwave transmission. The dedicated communication system can provide stable, timely and reliable communication network services, but the deployment of the dedicated emergency communi...
