Abstract
The invention discloses a separated mobile phone comprises a host-phone and a handset. The host-phone includes a wireless modem module, a main controller, a control signal interface, a digital audio interface, a low-power wireless transceiver module and a PDA device. The handset comprises a main controller, a display, a microphone, a speaker, a keyboard and a low-power wireless transceiver module. The low-power wireless transceiver module in host-phone can be set inside or outside. Communication modules between the host-phone and handset use Bluetooth protocol or Home Radio Frequency protocol. The host-phone and handset can access to public switched telephone network through a home cordless telephone.

9. A communication method of a separated mobile phone with PDA function, comprising a sending method and a receiving method:
-
the sending method including;
an audio signal coming from a microphone of a handset, after having been processed by a main controller of the handset, being sent to a low-power wireless transceiver module for transmitting;
the transmitted signal being received by a low-power wireless transceiver module in a host-phone, and being transferred to a wireless modem module through a digital audio interface;
after having been processed and modulated in the wireless modem module, the signal being emitted in air;
the receiving method including;
a signal coming from air, being demodulated by the wireless modem module in the host-phone and being recovered to an audio signal, which then being transferred to the low-power wireless transceiver through the digital audio interface;
the recovered audio signal being modulated by the low-power wireless transceiver and being transmitted to the handset in a short distance;
in the handset, the modulated audio signal being received and demodulated to an audio signal by the low-power wireless transceiver module;
the audio signal being sent to the speaker in the handset to output, under control of the main controller of the handset;
further including;
a control command, sent out by a keyboard in the handset, being first modulated by the low-power wireless transceiver module, and then transmitted to the low-power wireless transceiver module in the host-phone;
in the host-phone, the control command being solved by a control signal interface and the main controller, then being modulated and emitted to air by the wireless modem module;
a control command coming from air, being received and demodulated by the wireless modem module in the host-phone;
after having been passed through the main controller and the control signal interface, the control command being modulated and transmitted to the handset by the low-power wireless transceiver module in the host-phone;
in the handset, the control command being received by the low-power wireless transceiver module, and shown on a display after having been processed by the main controller. - View Dependent Claims (10)
