Abstract:
1. A method of identifying a caller at a device in signal communication with a cellular telephone system, comprising: receiving a page at the device from the cellular telephone system, the device having an identification tag; replying to the page with the location of the device; receiving a call having at least one of a data signal and a voice signal at the device in response to the reply to the page; registering a caller identification tag, activating an alert mechanism, and displaying the caller identification tag at the device in response to the received data signal; denying access to the voice services of a voice channel adapted to contain the voice signal to prevent establishment of a voice call; receiving at the device a voice channel assignment in response to the reply to the page and before receiving the call; returning at least one of receiver and a transmitter to the assigned voice channel; and acknowledging to the cellular telephone system the presence of the device on the voice channel; wherein a received cellular call is processed at the device for data signal content but not for voice services, thereby enabling identification of the caller absent voice communication with the caller.
