Patent ID: RE40910

Claim:
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 .
