Efficient prisoner tracking

摘要

A network tracking server-based service that implements an efficient network management of location requests associated with tracking a prisoner's wireless tracking device. The tracking server initiates location requests associated with a given prisoner (or the like) tracking device in a trustworthy, but much more efficient and manageable technique, from the perspective of the network. Network management of prisoner device tracking is made efficient when inside a given geofence, but once outside the prescribed geofence a more detailed inquisition is immediately launched—even before the top of the hour (or whenever the typical periodic location request occur). From a management perspective, once detected to no longer be inside (and thus is outside) an expected or assigned geofence, the prisoner tracking device is presumed less trustworthy, and thus then periodic location requests to the tracking device are initiated.

主权项

1. A method of tracking a wireless prisoner tracking device, comprising:
maintaining, at a tracking service server, a map of a plurality of prisoner tracking devices to a respective plurality of femto-cell IDs respectively assigned to serve each of said plurality of prisoner tracking devices, wherein the tracking service server comprises one or more computing devices; receiving, at said tracking service server, before a scheduled location check, an indication that one of said plurality of prisoner tracking devices is reported as being in communication with a femto-cell other than a respectively assigned femto-cell; prematurely initiating a network initiated location request, by said tracking service server, for said one of said plurality of prisoner tracking devices when reported as being in communication with said femto-cell other than said respectively assigned femto-cell; and ceasing, by said tracking service server, said network-initiated location requests for said one of said plurality of prisoner tracking devices when in communication with said respectively assigned femto-cell.
