Maritime wireless communication system and communication networking method

Abstract

The invention relates to a maritime wireless communication system and communication networking method, comprising a communication-in-moving system and a shore-based mobile communication base station. The communication-in-moving system is distributed on a ship, the ship is a link node, and the communication-in-moving system is composed of a terminal system, a control and routing module, a relay system, a WIFI module and a global positioning system. The communication-in-moving system distributed close to the shore achieves a communication ad-hoc network with the shore-based mobile communication base station, and via the control and routing module, links a terminal base-band module of the terminal system to a relay base-band module of the relay system, and the relay system continues to cover areas with no signals. Via a multi-node link mode, a maritime ad-hoc network is finally achieved, and a communication channel between the shore and the sea is built. The maritime wireless communication system and communication networking method are advantageous in that, though the ad-hoc network mode, and combination of the shore-based mobile communication base station, sea-shore communication for a maritime operator is achieved.

Description

technical field [0001] The invention belongs to the technical field of marine communication, and in particular relates to a marine wireless communication system and a communication networking method for data and voice communication of offshore operators. Background technique [0002] Maritime communication is related to the safety, communication and supervision of marine operators, and is also conducive to the healthy and sustainable development of the marine economy. [0003] At present, there are two ways for maritime communication at home and abroad: one is satellite communication system, and the other is digital walkie-talkie communication. Satellite communication occupies a dominant position in maritime communication due to its advantages of large coverage area, large communication capacity and flexible maneuvering, and is also the focus of current maritime communication applications. However, the high cost of satellite communication is the main difficulty in its promo...

AI Technical Summary

Problems solved by technology

Digital walkie-talkies can only perform point-to-point or point-to-multipoint maritime voice communication, and cannot access the public network, and cannot realize free shore-sea communication

[0004] According to the 3GPP agreement, the furthest coverage distance of mobile communication is 110 kilometers. Beyond this distance, due to delay, the signaling channel and data channel will interfere. Even if the signal can be received, the data cannot be parsed for communication.
