Satellite communication device and satellite communication system

摘要

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

1. A satellite communication device for transceiving information with a terminal connected to a LAN, transmitting the information received from the terminal to a WAN, via a satellite by a wireless signal, and receiving information from the WAN via the satellite by a wireless signal, comprising a processor, the processor comprising:
a determiner configured to determine availability of communication via satellite by wireless signal from the terminal to the WAN based on determination information that is acquirable from either one of communication via the LAN and the device itself without performing communication via the WAN via satellite by wireless signal, and for generating, when the communication from the terminal to the WAN is available via satellite by wireless signal, a communicable signal indicating that the communication to the WAN is available; and a notifier configured to receive, from the terminal, a communication checking signal for requesting to check the availability of the communication to the WAN via satellite by wireless signal, and transmitting without performing communication via the WAN via satellite by wireless signal, only when the communication from the terminal to the WAN is available via satellite by wireless signal, the communicable signal to the terminal in response to the communication checking signal.
