Methods, Devices, and Computer Readable Storage Devices for Tracking the Locations of Mobile Target Communication Devices with Respect to the Location of a Host Communication Device over Time

摘要

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.

主权项

1. A method, comprising:
determining, by a processor within a host communication device, a distance between the host communication device and a mobile target communication device at each of multiple times over a time period based on a received signal emitted by the mobile target communication device at each of the multiple times; determining, by the processor, an amount of time within the time period that the distance between the host communication device and the mobile target communication device is within a distance threshold based on the distance determined for each of the multiple times; determining, by the processor, 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 within the time period; and initiating transmission of a notification to a third party via a gateway responsive to determining that 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.
