摘要

A location tracking system is provided for tracking the location of a child or other individual. The location tracking system includes a location server and one or more location tracking devices. Communication protocols are provided for sending location data and network 5 data to the location server in an efficient manner during a single communication session. The network data can be stored in a geolocation database and used to estimate the location of the location tracking device when GPS positioning is not available.
