Problems solved by technology

[0003] TETRA digital trunking communication system is a professional mobile communication system based on digital time division multiple access technology. It is a traditional and relatively mature narrowband trunking communication system. Error and anti-interference ability, the advantages of wide coverage, but the disadvantage is that the transmission bandwidth is narrow, only voice services can be provided, broadband transmission and video applications cannot be provided

Abstract

The invention discloses a TETRA and LTE-based adaptive rail transit communication system and a communication method. The system comprises an onboard platform and a dispatching platform, wherein the onboard platform comprises a terminal, a TETRA system channel machine and an LTE system channel machine; the dispatching platform comprises a dispatching client and a dispatching server; and the onboardplatform and the dispatching platform realize communication through an antenna and a base station. An LTE broadband cluster is adaptively combined with a TETRA system, the rail transit communicationsystem can provide not only good voice services, but also broadband transmission and video services, and while the high communication rate is ensured, the service function of the railway private network is expanded, the demand of a passenger for Internet access is met, and the travel satisfaction of the passenger is improved.

Description

technical field [0001] The invention relates to a rail transit cluster communication system and a communication method, in particular to an adaptive rail transit communication system based on TETRA and LTE, and also to a rail transit communication method for the adaptive rail transit communication system. Background technique [0002] The network is becoming more and more important in modern people's life, and the network and life are inseparable. The railway private network must not only meet the development of railway business and the customization needs of the industry, but also improve the travel satisfaction of passengers, that is, the Internet demand of passengers. The limitations of the narrow-band digital cluster TETRA valve stem widely used in the current railway private network are becoming increasingly prominent, and the new generation of LTE subway wireless private network is the trend of the subway wireless network. [0003] TETRA digital trunking communication...
