A ship-wide mobile phone communication system that supports multi-operator signal integration of public network mobile phones

Abstract

The invention discloses a ship-wide mobile phone communication system that supports multi-operator signal fusion of public network mobile phones, and belongs to the technical field of ship electronic information. The invention uses a multi-operator digital wireless distribution system to realize fusion access with room division equipment so that Reduce the cost of equipment deployment. In the case where the mobile phone base station signal of the public network in the open sea is not covered, the ship-borne cellular mobile communication base station will transfer the signal of the public network mobile phone to the network through the ship-borne satellite communication channel. Mobile phone base stations and ship outdoor antennas enable public network mobile phone signals to enter the network, and expand the supported types of public network mobile phone terminals to provide more abundant application capabilities for maritime ship public network mobile phone users.

Description

technical field [0001] The invention belongs to the technical field of ship electronic information, and more specifically relates to a ship-wide mobile phone communication system supporting multi-operator signal fusion of public network mobile phones, mainly aimed at the mobile communication functions of mobile phone users of the whole ship's public network in the case of near and far seas. The realization of the system provides convenient public network mobile communication services for the daily life and work of the crew. Background technique [0002] At present, marine ship mobile communication generally relies on public network cellular mobile communication signals in offshore conditions and satellite communication in remote sea conditions. The former has weak coverage of signals inside metal cabins of ships, and the latter is difficult to support public network mobile phone users. , the lack of instant mobile communication methods between seafarers and shore-based publi...
