A radio control section in a mobile station determines the type of communication either based on the contents of a control signal demodulated by a voice modulator/demodulator and a high-speed data modulator/demodulator or based on the state of connection of an external device (not shown) to I/O terminals. The radio control section controls a switch so that modulation and demodulation may take place selectively in the modulator/demodulator for voice communications or in modulator/demodulator for high-speed data communications. The mobile station thus selectively uses a radio line for voice communications or a radio line for high-speed data communications.

Une partie de commande radio dans une station mobile détermine le type de communication soit sur la base du contenu d'un signal de commande démodulé par un modulateur/démodulateur de voix et un modulateur/démodulateur de données à haut débit, soit sur la base de l'état de la connexion d'un dispositif extérieur (non illustré) à des bornes ES. La partie de commande radio commande un commutateur de manière que la modulation et la démodulation puissent avoir lieu sélectivement dans le modulateur/démodulateur pour les communications vocales ou le modulateur/démodulateur pour les communications de données à haut débit. La station mobile utilise ainsi sélectivement une ligne radio pour les communications vocales ou une ligne radio pour les communications de données à haut débit.
