MOBILE COMMUNICATION TERMINAL AND CAR MOUNTED ELECTRONIC DEVICE

摘要

BT wiring sections 40 and 6 are provided respectively at a mobile telephone set MS and a car audio device AS. When a user of the mobile telephone set MS gets on a car CR, a BT radio link is established between the mobile telephone set MS and the car audio device AS, and a hands-free communication mode is set to the mobile telephone set MS and car audio device AS. Then, the communication speech data received from/transmitted to a mobile communication network via a W-CDMA radio link is transferred between the mobile telephone set MS and the car audio device AS, thereby enabling hands-free communication.
