Heterogeneous network fusion communication device and communication method for emergency logistics

Abstract

The invention provides a heterogeneous network fusion communication device and communication method for emergency logistics. The device includes a fusion service management system and a heterogeneous network communication module; the fusion service management system includes: a multi-source information access system, which completes communication network access of different protocols through the communication transceiver module, and transfers the received data of different communication networks Add packet header information according to the defined identifier to form a new data frame format for transmission; the protocol extraction and conversion system extracts the communication protocol mapped in the protocol pool according to the packet header identifier of the received data flow, analyzes the data flow, and converts the analyzed data 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 business communication services of audio, video and data. It can maximize the use of communication resources in complex network environments, and solve the problems of single data source and independent communication networks.

Description

technical field [0001] The invention relates to the field of communication, in particular to a heterogeneous network fusion communication device used for emergency logistics. Background technique [0002] Various large-scale extreme and sudden events, natural disasters and industrial accidents have brought great challenges to the logistics 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 complete, but various communication methods are based on The respective networking methods are applied to form independent networks and systems. Therefore, there are disadvantages of complex system construction, insufficient data acquisition, scattered information, an...
