Abstract
Apparatuses, methods, and systems for signaling proximity of mobile devices. First activity information of a first mobile device and second activity information of a second mobile device are accumulated. A proximity boundary is established for the first mobile device. A location of the first mobile device is determined from the first activity information and a location of the second mobile device is determined from the second activity information. A determination is made whether the second mobile device is on or within the proximity boundary of the first mobile device. An alert is sent to at least the first mobile device that the proximity boundary has been breached when the second mobile device is on or within the proximity boundary of the first mobile device.
