ABSTRACT:
A portable telephone capable of background location transmission response, and methods which can be executed by such a telephone or a system using such a telephone. In one such portable telephone, a position locator which, in response to a location request signal, can determine the location of the portable telephone and generate a corresponding location signal. A receiver receives an incoming call signal and an incoming location request signal. A user interface has: an audio or visual user output device which can reproduce audio or visual information in an incoming call signal as a corresponding audio or visual display; and an audio user input device which generates an audio output signal corresponding to a user's voice. An alert generator which, in response to a received incoming call signal, generates a first physical characteristic to indicate an incoming call to a user of the portable telephone. A location request detector which, in response to a received location request signal, can direct the location request signal to the position locator without activating the alert generator. A transmitter to transmit a location signal generated by the position locator in response to a received location request signal, and to transmit the audio output signal.
