    • A mobile communication terminal equipment is mounted in a vehicle and can utilize both the satellite and terrestrial communication systems. The mobile communication terminal equipment includes a satellite transceiver and a portable set. The satellite transceiver has a satellite transmission/reception circuit. As required, the portable set is disconnected from the satellite transceiver to be carried by the user. The portable set includes a terrestrial transmission/reception circuit, a signal input/output circuit and a connection selecting switch. The connection selecting switch is automatically controlled to connect the signal input/output circuit selectively to one of the satellite and terrestrial transmission/reception circuits. When the satellite transmission/reception circuit is in connection with the signal input/output circuit, the communication through the satellite wireless communication system can be carried out. When the terrestrial transmission/reception circuit is connected to the signal input/output circuit, the communication through the terrestrial wireless communication system can be carried out.
    • 移动通信终端设备安装在车辆中并且可以利用卫星和地面通信系统。 移动通信终端设备包括卫星收发机和便携式设备。 卫星收发器具有卫星发射/接收电路。 根据需要,便携式设备与用户携带的卫星收发器断开连接。 便携式设备包括地面发射/接收电路,信号输入/输出电路和连接选择开关。 连接选择开关被自动控制以将信号输入/输出电路选择性地连接到卫星和地面发射/接收电路之一。 当卫星发送/接收电路与信号输入/输出电路连接时,可以进行通过卫星无线通信系统的通信。 当地面发射/接收电路连接到信号输入/输出电路时,可以进行通过地面无线通信系统的通信。
