Whole-ship mobile phone communication system supporting public network mobile phone multi-operator signal fusion

Abstract

The invention discloses a whole-ship mobile phone communication system supporting public network mobile phone multi-operator signal fusion. The invention belongs to the technical field of ship electronic information. According to the invention, a multi-operator digital wireless distribution system is adopted to realize fusion access with indoor distribution equipment, so that the equipment deployment cost is reduced; under the condition that signals of the open sea public network mobile phone base station are not covered, the shipborne cellular mobile communication base station achieves publicnetwork mobile phone signal network access through shipborne satellite communication channel transfer. Public network mobile phone signal network access is realized by the public network mobile phonebase station and the ship outdoor antenna within the signal coverage range of the offshore public network mobile phone base station, the supported public network mobile phone terminal types are expanded, and richer application capability is provided for offshore 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...
