Problems solved by technology

However, in the case of using this method, communication charges will be incurred if the main line is based on a specific rate system.
[0010] In addition, this problem is not limited to Ping, and it is a common problem in other methods as long as the method of actually using satellite communication to confirm whether communication is possible or the communication environment, etc.

Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1It is a block diagram of a satellite communication system 1 for performing satellite communication between ships and land bases.

[0041] like figure 1 As shown, communication via artificial satellite 30 (satellite communication) may be used when a ship communicates with a land base (building, etc.). In addition, in figure 1 Although only one artificial satellite 30 is shown in the figure, there are actually a plurality of artificial satellites, and an appropriate artificial satellite can be selected according to the position of the ship, the communication service used, and the like.

[0042] In addition, in the present embodiment, two satellite communication devices are installed on the ship, and communication is performed using one of the satellite communication devices depending on the situation. The satellite communication used in each satellite communicati...

Abstract

A satellite communication device (12, 14) is provided. The satellite communication device (12, 14) includes a determiner (24) for determining availability of communication from a terminal (15, 16, 17, 18) to a WAN based on determination information acquirable from either one of communication via a LAN and the device (12, 14) itself without performing communication via the WAN, and for generating, when the communication from the terminal (15, 16, 17, 18) to the WAN is available, a communicable signal indicating the communication to the WAN being available. The satellite communication device (12, 14) also includes a notifier (25) for receiving, from the terminal (15, 16, 17, 18), a communication checking signal for requesting to check the availability of the communication to the WAN, and transmitting, when the communication from the terminal (15, 16, 17, 18) to the WAN is available, the communicable signal to the terminal (15, 16, 17, 18).

Description

technical field [0001] The present invention mainly relates to a satellite communication device for communicating via an artificial satellite. Background technique [0002] Conventionally, there are known techniques for performing communications such as telephone, facsimile, and the Internet via artificial satellites. Communication via artificial satellites (hereinafter referred to as satellite communication) is used, for example, in areas (seas, isolated islands, etc.) where wired and wireless communication facilities are not installed. Patent Document 1 discloses a technique employed when satellite communication is used in an aircraft or the like. [0003] Patent Document 1 discloses a technology enabling calls and communications using a mobile phone in an aircraft. Specifically, an aircraft includes an antenna for satellite communication, and the like. The network of mobile phones in the aircraft and the network of base stations on land are connected by this satellite ...
