ABSTRACT:
An alert signal is generated based on the geographical position of a device and/or based on time or date. The alert signal is generated when the device is within a certain distance from a predefined location. An actual position of the device, the location of a place of interest, and a request for an alert signal associated with the location of the place of interest are stored. The actual position of the device is compared with the location of the place of interest. The alert signal is generated when the distance between the actual position of the device and the location of a place of interest is less than a predetermined value.
