Mobile communication terminal equipment usable for both satellite and terrestrial communications
First Claim
1. A mobile communication terminal equipment mountable in a vehicle comprising:
- a satellite transceiver mountable in said vehicle and including a satellite transmission/reception circuit for transmitting and receiving signals through a satellite wireless communication system; and
a portable set disconnectable from the satellite transceiver so that the set can be carried by a user, said portable set comprising;
a terrestrial transmission/reception circuit for transmitting and receiving signals through a terrestrial wireless communication system;
a signal input/output circuit for inputting signals from the user and for outputting signals to the user; and
a connection controller and switching means for selectively connecting the signal input/output circuit to one of the satellite transceiver and terrestrial transmission/reception circuits when said portable set is connected to said satellite transceiver and for connecting said signal input/output circuit to said terrestrial transmission/reception circuit when said portable set is disconnected from said satellite transceiver, wherein when said portable set is disconnected from said satellite transceiver, a user of said portable set may carry out terrestrial wireless communication immediately without the necessity of making any further reconnections of communication equipment components, and further wherein a size of said satellite transceiver is reduced by eliminating therefrom the need for any input/output device by virtue of said signal input/output circuit being provided in said portable set.

Abstract
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.
