    • 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).
    • 提供了一种卫星通信设备(12,14)。 卫星通信设备(12,14)包括一个确定器(24),用于根据从LAN中的任一个通信中可以获得的确定信息确定从终端(15,16,17,18)到WAN的通信的可用性, 设备(12,14)本身,而不经由WAN进行通信,并且当从终端(15,16,17,18)到WAN的通信可用时,生成指示与WAN通信的可通信信号是可用的 。 卫星通信设备(12,14)还包括用于从终端(15,16,17,18)接收用于请求检查到WAN的通信的可用性的通信检查信号的通知器(25),以及 当从终端(15,16,17,18)到WAN的通信可用时,发送到终端(15,16,17,18)的可通信信号。
