1. A system comprising:
- communication device adapted to transmit and receive information over a radio frequency communication link; and
one or more base stations adapted to transmit voice communications between said communication device and a public switched telephone network (PSTN), wherein said communication device comprises;
a first power supply;
a computing unit, coupled to the first power supply;
a second power supply;
a radio communication unit coupled to the second power supply; and
a switch adapted to selectively couple the radio communication unit to the second power supply, to provide first and second modes of operation, wherein the first mode of operation enables the computing unit and the radio communication unit, and the second mode of operation disables the radio communication unit and enables the computing unit.

Abstract
A method and apparatus for disabling the communication functionality (i.e., disabling the transmission and/or reception of RF signals) of an integrated device, while still providing access to the local functionality of such device. A control and select function, such as a switch that is implemented by hardware or software or a combination thereof, is provided in an integrated device to allow the end user of the device to access the local data processing functionality of the device, even while the wireless communication functionality of such device is disabled.

6. A method comprising:
-
transmitting voice communications between a public switched telephone network (PSTN) and portable communication device over a radio frequency communication link; providing a subscriber with access to user-operated computing functionality of said portable communication device and access to transmitting signals to and receiving signals from one or more base stations through said radio frequency communication link; and subsequently disabling said access to transmitting said signals while maintaining said access to the user-operated computing functionality and the access to receiving signals. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method comprising:
-
transmitting voice communications between a public switched telephone network (PSTN) and portable communication device over a radio frequency communication link, said portable communication device having interactive data processing functionality and a wireless signal communication functionality; simultaneously enabling access to the interactive data processing functionality and the wireless signal communication functionality; and in response to detecting an event, providing notification to disable the wireless signal communication functionality while simultaneously maintaining the access to the interactive data processing functionality by use of a selection mechanism. - View Dependent Claims (19, 20)
