Railway station comprehensive bearing system based on LTE + DMR broadband and narrowband fusion technology

Abstract

The invention discloses a railway station integrated bearing system based on an LTE + DMR broadband and narrow band fusion technology, and the system comprises: an LTE broadband wireless communication system which covers a broadband demand operation area of an integrated station; a DMR narrow-band wireless communication system which covers all areas of the comprehensive station; a dual-network fusion device which is provided with a unified interface, wherein the LTE broadband wireless communication system and the DMR narrow-band wireless communication system are registered to the dual-network fusion device through the unified interface, and then fusion communication and intercommunication of systems of different voice formats are achieved through the dual-network fusion device; and a service application system which realizes IP-based packet data transmission service based on the dual-network fusion device, and achieves interconnection and intercommunication between the LTE cluster service and the DMR service. According to the system, the respective technical advantages of LTE and DMR and functions which can be applied in the future are fully utilized, the increasing railway station communication service requirement is met, interconnection with a railway station information system is achieved, and the operation safety of all the systems is guaranteed.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to an integrated bearing system for railway stations based on LTE+DMR broadband and narrowband integration technology. Background technique [0002] With the development of railway informatization construction, currently railway station users not only require reliable voice services, but also gradually have more demands for big data services such as video surveillance and multimedia broadcasting. Driven by the rapid development of 4G technology, it is the general trend to evolve to LTE-based technology. However, for a long period of time in the future, the LTE private network broadband system will face the influence and restrictions of many factors such as spectrum policy, technical standard maturity, network security and reliability, and user cost. Therefore, the promotion and popularization of LTE broadband trunking technology cannot be accomplished overnight. It is necessar...

Problems solved by technology

At present, there is no precedent for the high integration of the two technologies (LTE+DMR). Even if the two technologies are adopted at the same time, they are independent of each other. The true one-network coverage has not been achieved, and the service data cannot be shared and unified smoothly. dispatch command
