Integrated Bearing System of Railway Station Based on LTE+DMR Broadband and Narrowband Fusion Technology

Abstract

The invention discloses an integrated bearing system of a railway station based on LTE+DMR wide-narrowband fusion technology, which includes: an LTE broadband wireless communication system covering the broadband demand operation area of ​​the integrated station; a DMR narrowband wireless communication system covering the integrated station There are all areas in the site; the dual-network fusion equipment has a unified interface. The LTE broadband wireless communication system and the DMR narrowband wireless communication system register with the dual-network fusion equipment through a unified interface, and then realize the fusion communication and different voice format systems through the dual-network fusion equipment. Intercommunication; business application system, based on dual-network fusion equipment to realize IP-based packet data transmission services, and interconnection and intercommunication between LTE cluster services and DMR services. The above-mentioned systems make full use of the respective technical advantages of LTE and DMR and the functions that may be applied in the future to meet the growing needs of railway station communication services, realize the interconnection with the railway station information system, and ensure the operation safety of each system.

Description

technical field [0001] The invention relates to the technical field of rail transit, and in particular to a railway station and yard comprehensive bearing system based on the LTE+DMR wide-narrowband fusion technology. Background technique [0002] With the development of railway informatization construction, railway station users are not only required to provide 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, the evolution to LTE-based technology has become the general trend. 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 popularization of LTE broadband trunking technology cannot be achieved overnight. It is necessary t...

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
