Abstract

The present invention includes a method and apparatus for a handheld personal communications device capable of simultaneous wireless voice communications service and wireless data communications service. The invention includes providing wireless voice communications service to a first line of a handheld personal communications device and simultaneously providing wireless data communications service to a second line of the handheld personal communications device.

Claims

1. A handheld personal communications device capable of simultaneous wireless voice communications and wireless data communications comprising:

a housing;

a first wireless radio transceiver disposed within the housing for operative voice communication across a first communications channel;

a second wireless ratio transceiver disposed within the housing for operative data communication across a second communications channel;

a sensor operatively connected to the first wireless radio transceiver for transducing voice sound information;

a speaker operatively connected to the first wireless radio transceiver for producing voice sound information;

an intelligent control operatively connected to the second wireless ratio transceiver for sending and receiving data; and

a display operatively connected to the processor capable of displaying a visual representation of data received over the second wireless transceiver.

2. A method for providing wireless voice communication service and wireless data communications service to a handheld personal communications device comprising:

providing wireless voice communications service to a first line of the handheld personal communications device;

simultaneously providing wireless data communications service to a second line of the handheld personal communications device;

charging for the voice communications service; and

charging for the data communications service.

3. The method of claim 2 wherein the wireless voice communications service is selected from the set comprising PCS, CDPD, AMPS, and GSM.

4. The method of claim 2 wherein the wireless data communications service is selected from the set comprising TCP/IP and WAP.

5. The method of claim 2 wherein the first line is provided by a first wireless transceiver and the second line is provided by a second wireless transceiver.

6. The method of claim 2 wherein the first line is provided by a first channel and the second line is provided by a second channel.
