Mobile communication system in traffic field

Abstract

The invention discloses a mobile communication system in the traffic field, which comprises a user network, an access network and an internet, the user network is connected with the access network through an antenna, and the access network is connected with the internet in a wireless communication mode. The user network comprises a central compartment local area network and a plurality of compartment local area networks connected with the central compartment local area network, and the central compartment local area network comprises a vehicle-mounted antenna VMA, a central server CVS connected with the vehicle-mounted antenna VMA, a vehicle-mounted switch VSW connected with the central server CVS, a bicycle server LVS connected with the vehicle-mounted switch VSW, a 4G / 5G small base station connected with the bicycle server LVS and an AP. The difference between the compartment local area network and the central compartment local area network is that no vehicle-mounted antenna VMA and no central server CVS exist, adjacent vehicle-mounted switches VSW are interconnected, the access network comprises a satellite, and the satellite is in communication connection with the vehicle-mounted antenna VMA and the Internet. The problem of wireless network coverage of three public transport means of trains, steamships and airplanes is solved, and passengers can access the Internet when taking the train.

Description

technical field [0001] The invention relates to the technical field of traffic communication, in particular to a mobile communication system in the traffic field. Background technique [0002] At present, mobile communication base stations are mainly deployed in densely populated areas on land. In addition, the optical fiber backhaul method is used to realize the connection with the core network. [0003] Vehicles such as sea ferries and airplanes operate far away from the land, so land base stations cannot cover them, which also makes it difficult to achieve wireless communication coverage on such vehicles. [0004] At present, my country's high-speed rail covers a wide range. To achieve full mobile communication coverage along the high-speed rail, it is necessary to cover a large number of communication base stations along the high-speed rail. At present, 4G wireless communication signal coverage is roughly realized along the high-speed rail in my country. 5G mobile sig...
