Mobile communication system catering to sea ships

Abstract

The invention discloses a mobile communication system capable of providing wireless communication support to mobile users on sea ships. The system is combined by a honeycomb mobile communication network, a sea mobile self-organization network and a satellite mobile communication network through a sea satellite gateway, a ship honeycomb gateway and a land gateway. The system provides a plurality of communication methods to sea mobile users and land users. The sea mobile users and the land users can choose proper wireless communication network to build communication connection through a wireless network choosing method which is disclosed by the invention. The device and the method can reduce the deploying cost of the communication network and the communication cost of the mobile users, can expand the supported mobile terminal types, and can provide richer services to the sea mobile users.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a construction method, a communication method and a related device of a mobile communication system oriented to ships at sea. Background technique [0002] With the development of ocean-going fishing and ocean-going transportation in our country, marine ship mobile users need convenient and effective communication and business support in any sea area. At present, the communication equipment used by ships at sea (such as fishing boats, cargo ships, etc.) includes SSB radio stations, VHF wireless phones, ultrashort wave walkie-talkies, cellular phones and satellite phones. Single sideband short-wave radio transmits short-wave in the atmospheric ionosphere to realize the transmission of calls. It has a long distance, a lower cost than satellite phones, and convenient maintenance of terminal equipment. Its disadvantages are that there are coverage blind spots in short...

AI Technical Summary

Problems solved by technology

Cellular mobile phones (such as CDMA mobile phones with global positioning system GPS) are relatively cheap, and the communication charges are cheap; the disadvantage is that the signal coverage distance of cellular base stations is limited, usually within dozens of nautical miles in the offshore

Satellite mobile communication (such as Inmarsat Maritime Satellite System) can be suitable for ocean-going high-sea ships, but terminal equipment purchase costs, maintenance and update costs, and communication fees are relatively high
