Abstract

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.
