Heterogeneous network converged communication device and communication method for emergency logistics

Abstract

The present invention provides a heterogeneous network converged communication device and a communication method for emergency logistics. The device comprises a converged service management system anda heterogeneous network communication module. The integrated service management system comprises: a multi-source information access system, which completes the communication network access of different protocols through a communication transceiver module, and adds packet header information to the received data of different communication networks according to the prescribed definitions and identifiers to form a new data frame format for transmission; The protocol extraction conversion system extracts the communication protocol mapped in the protocol pool according to the packet header identification of the received data stream, parses the data stream, and converts the parsed data into IP data packets for interactive transmission. The network management system completes the resource allocation, QoS service, access network management and alarm of the converged network. The business service system provides one or more service communication services of audio, video and data. It can make the most of communication resources in complex network environment and solve the problem of single data source and each communication network independent of each other.

Description

technical field [0001] The invention relates to the communication field, in particular to a heterogeneous network fusion communication device for emergency logistics. Background technique [0002] All kinds of large-scale extreme and sudden events, natural disasters, and industrial accidents have brought huge challenges to the logistics and disaster relief of the emergency system. [0003] All kinds of information and data are the basic elements and important basis for the operation of the emergency logistics system. The current main emergency communication methods include wireless trunking communication, Beidou communication and satellite communication. The communication methods and technologies are relatively perfect, but all communication methods are based on The respective networking methods are applied to form independent networks and systems. Therefore, there are drawbacks such as complex overall system construction, insufficient data acquisition, scattered informatio...
