Maritime wireless communication method and apparatus
First Claim
1. A maritime communication apparatus, comprising:
- a land-based network communication unit configured to communicate with a land-based communication network;
a maritime network communication unit configured to communicate with a maritime communication network; and
a communication control unit configured to link communication of the land-based network communication unit with communication of the maritime network communication unit in accordance with a destination address of data received from one of the land-based network communication unit and the maritime network communication unit, the communication control unit being configured to, upon determining that the destination address of the received data is not the maritime communication apparatus,send the received data to the maritime communication network when the data is received from the land-based communication network, andsend the received data to the land-based communication network, or relay the data to another maritime communication apparatus in accordance with the determined destination address, when the data is received from the maritime communication network,wherein the land-based network communication unit includes a plurality of wireless network connection means corresponding to a plurality of land-based communication network connection systems,wherein the communication control unit causes communication with the land-based communication network to be performed via the other maritime communication apparatus when communication with the land-based communication network via the other maritime communication apparatus is possible when communication with the land-based communication network via the land-based network communication unit is impossible,wherein the communication control unit causes the data to be sent via International Maritime Satellite Organization (INMARSAT) or Very Small Aperture Terminal (VSAT) satellite communication when communication with the land-based communication network via the other maritime communication apparatus is impossible and required bandwidth is equal to or higher than a first level, andwherein the communication control unit causes the data to be sent via Automatic Identification System (AIS) communication when communication with the land-based communication network via the other maritime communication apparatus is impossible and required bandwidth is lower than the first level and equal to or higher than a second level.

7. A maritime communication method of a maritime communication apparatus, the method comprising:
-
receiving data from one of a maritime communication network and a land-based communication network; determining a destination address of the received data; and upon determining that the destination address of the received data is not the maritime communication apparatus, sending the received data to the maritime communication network when the data is received from the land-based communication network, and sending the received data to the land-based communication network, or relaying the received data to another maritime communication apparatus in accordance with the determined destination address, when the data is received from the maritime communication network, when direct communication with the land-based communication network is impossible, communicating with the land-based communication network via another maritime communication apparatus, when communication with the land-based communication network via the other maritime communication apparatus is impossible and required bandwidth is equal to or higher than a first level, sending the data via International Maritime Satellite Organization (INMARSAT) or Very Small Aperture Terminal (VSAT) satellite communication, and when communication with the land-based communication network via the other maritime communication apparatus is impossible and required bandwidth is lower than the first level and equal to or higher than a second level, sending the data via Automatic Identification System (AIS) communication. - View Dependent Claims (8, 9, 11)
