Index of suspicion determination for communications request

摘要

The risk that an incoming emergency call is a prank call is presented in real-time to the called party, in the form of, e.g., an index of suspicion. An index of suspicion aggregation server quantifies, qualifies, and aggregates risks, suspicions, and/or threats relevant to a call center to formulate a scale of suspicion. Metrics are acquired (e.g., calling device location information, device configuration information, caller information, etc.) relevant to each communications request made to a call center and uses acquired metrics to rate communications requests based on a known scale of suspicion. Once a suspicion rating is determined for a communications request, the communications request is routed to a relevant call-taker terminal, as is the index of suspicion for that incoming call. Real time presentation of the index of suspicion enables call-takers to make better call-handling decisions based on risk analysis and historical call data associated with a given caller.

主权项

1. A method of providing a real-time index rating of suspicion that an incoming call may be a prank call, comprising:
requesting a current location of a wireless calling device to an incoming call, from a network positioning server; comparing said obtained current location of said wireless calling device to locations of known active emergency events; determining a first level of confidence that said incoming call relates to a known emergency event based on said comparison of said current location of said wireless calling device to locations of known active emergency events; accessing a call history database to determine a second level of confidence from a call history relating to said wireless calling device; accessing a call forensic database to determine a third level of confidence relating to a pattern of known prank calls; aggregating said first level of confidence, said second level of confidence, and said third level of confidence, into an index of suspicion; and providing said index of suspicion rating in real-time to a called device during said incoming call.
