Ocean ultra-short wave remote wireless communication and integrated information service system

Abstract

The invention discloses a service system of ocean ultra-short wave wireless telecommunications and comprehensive information, which comprises an integrated service controlling and switching center, a base station with special frequency band on the ocean, and a shipborne mobile terminal with built-in GPS; the system adopts a mode of MPT-1327 signaling fast frequency-shift key modulation, a duplex mode or a half duplex mode; the base station uses a 2M digital circuit or a satellite to connect with the integrated service controlling and switching center, the latter is connected with an LBS location service platform, a management platform, a distress alerting platform, a value added service platform and PSTN or PLMN. The LBS location service platform is connected to monitoring centers at different levels through DDN or WAN. The service system of the invention solves the mobile communication problem of ships which locate within 300 nautical miles off the shore and realizes auto roaming anda plurality of communication services of users in an ocean network. Numbers of users on the ocean can be realized to be bundled with phone numbers, and real-time monitoring as well as centralized command and management of the ships on the ocean by the monitoring centers at different levels can be realized.

Description

technical field [0001] The invention relates to ultrashort wave long-distance wireless communication, in particular to a marine ultrashort wave long-distance wireless communication and integrated information service system. Background technique [0002] Maritime wireless communication has always been a major problem in the global wireless communication field, and maritime wireless communication is very important because it is an important means of guaranteeing maritime safety. At present, the vast majority of fishing boats in our country are small and medium-sized fishing boats, and their working areas are mostly within 100 nautical miles offshore. The main means of communication are 90C series ultrashort wave radios and short wave SSB radios, which have relatively single functions and are very inconvenient to use. In developed countries, the communication with the land beyond 20 nautical miles offshore is mainly resolved by satellites, but due to the high cost, it cannot me...

AI Technical Summary

Problems solved by technology

At present, the vast majority of fishing boats in our country are small and medium-sized fishing boats, and their working areas are mostly within 100 nautical miles offshore. The main means of communication are 90C series ultrashort wave radios and short wave single sideband radios. The functions are relatively simple and it is very inconvenient to use.

In developed countries, the communication with the land beyond 20 nautical miles is mainly resolved by satellites, but due to the high cost, it cannot meet the large communication traffic business needs of the vast number of small and medium-sized offshore fishing vessels in my country
