Abstract
A distance between a host communication device and a mobile target communication device at multiple times over a time period based on a received signal emitted by the mobile target communication device. An amount of time that the distance between the host communication device and the mobile target communication device is within a distance threshold is also determined. A determination is further made whether the amount of time the distance between the host communication device and the mobile target communication device is within the distance threshold is less than a predetermined amount of time. If the amount of time that the distance between the host communication device and the mobile target communication device is within the distance threshold is less than the predetermined amount of time, transmission of a notification to a third party is initiated via a gateway.
