PROBLEM TO BE SOLVED: To avoid inconvenience that the user always has to carry a large sized terminal by mechanically coupling a mobile satellite communication terminal and a ground wave portable terminal and connecting electrically a voice conversion section at a terminal side of the ground wave portable terminal and a mobile satellite communication terminal function of a main body terminal side when they are coupled. SOLUTION: An iridium main body terminal A and a ground wave portable terminal B are mechanically coupled to connect electrically a connector section 3 of the terminal B and a connector container section 12 of the terminal A. PCM data from a CODEC 37 at the side of the portable terminal B are sent to a VOCODER 39 of a side of the main body terminal A via the connector section 3, and data of an MMI 38 at a side of the ground wave portable terminal B are sent to a link layer 40 at a side of the main body terminal A. Electric coupling of the connector section 3 is detected by a detection circuit at the side of the portable terminal B, a selection key 17F is depressed to light a selection key LED 17f, and a permission circuit 45 at an output side of the CODEC 37 sends the PCM data from the CODEC 37 to the main body terminal A via the connector section 3. |
