Unique global identifier header for minimizing prank emergency 911 calls

摘要

A prank call server that performs 911 prank call filtering over a 911 emergency call system, prior to routing a 911 call to a PSAP. The inventive prank call server identifies prank calling devices, regardless of current service subscription, by retrieving and analyzing emergency call data pertaining to detected prank 911 calls. The prank call server assigns a unique global identifier to each 911 call detected on the 911 emergency call system. Unique global identifiers enable a PSAP to uniquely identify prank 911 calls that are identified thereon. A PSAP transmits a prank call signal and a relevant unique global identifier to the prank call server, for each prank 911 call that is detected. A prank call signal/unique global identifier combination triggers the prank call server to store all available call data for a referenced prank 911 call in to a prank call database, for subsequent prank call filtering analysis.

主权项

1. A method of providing 911 prank call filtering over a 911 emergency call system, comprising:
receiving at a physical prank call server, a prank call signal associated with a unique global identifier assigned to a given 911 call, when said given 911 call is detected at a PSAP to be a prank 911 calling device; obtaining a location of said detected prank 911 calling device; querying a prank call database for correlation between a location and unique global identifier of a calling device of said given 911 call with a pre-identified prank calling device; and dropping said detected prank 911 call from said prank 911 calling device when information maintained within said prank call database correlates said given 911 call with an identified prank calling device.
