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.

摘要:
A timing management node that assigns and adjusts timeout values for a time-constrained complex distributed system based on the nature of a system request, preferences of a customer furnishing a system request, and/or a current state of a complex distributed system. A timing management node evaluates information regarding a system request and information regarding a current state of a complex distributed system to generate timing requirements for the system request. Timing requirements are compiled in a timing policy messager and passed amongst nodes of a complex distributed system with process flow. Timing requirements may be revised during request processing to reflect events that have occurred within the distributed system. A timing policy message contains a timeout value and a total time elapsed parameter for a system request, to permit a complex distributed system to make smarter processing decisions based on a known time remaining to process the given system request.

An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool. A plurality of ESQKs are grouped into a pool of emergency service keys “ESQK Pool ID”, each including anywhere from 1 to N number of ESQKs. Each ESQK preferably has a “Timestamp”, information relating to the specific emergency E911 call (“Call Data ID”), a guard timer, and an optional hold timer. The ESQK having a Call Data ID=“NULL”, and having the oldest Timestamp, is chosen for selection. If no such ESQK has both Call Data ID=NULL and the oldest Timestamp is found, then the ESQK with merely the oldest Timestamp is selected. The timestamp is reset to a current time plus a guard timer, or hold timer if desired.

摘要:
A technique and apparatus to allow a determination of an MSAG-valid address by use of normalized house numbers included in address entries in an MSAG Address data store, to facilitate the simple match of an input civic/postal address against entries in a MSAG data store based on the use of a normalization of the house numbers. The house number normalization allows for an easy lexicographical determination as to whether or not the input civic/postal house number falls with the range of house numbers in the MSAG data store. The inventive process and apparatus pre-stores normalized house number fields in an MSAG address data store, and then normalizes house numbers in a civic/postal address associated with an emergency call. The normalized numbers in the input civic/postal address associated with the emergency call are then lexicographically matched with normalized entries in an MSAG address data store.
摘要:
The present invention is used in an emergency network to identify and provide the correct public safety access point (PSAP) to service an emergency call originating from a Voice Over Internet Protocol (VoIP) subscriber. Data stores in an emergency services network associate PSAPs to an input ZIP code obtained from a street address returned from an MSAG relating to a VoIP call, and PSAPs to an input ESN. An emergency caller's civic street address is matched against a nationwide MSAG data store to result in a MSAG ESN. From the street address, the emergency caller's ZIP code is matched to a PSAP in an appropriate ZIP/PSAP data store. A matching PSAP from both the ZIP/PSAP and PSAP/ESN data stores determines with great reliability the identity of the proper PSAP for that emergency caller.
摘要:
The correct PSAP that can service an emergency call originating from a VoIP terminal with the caller's geographic information embedded in the call signaling is determined. A latitude and longitude is extracted from geographic information that is embedded in the call signaling. In some cases only the civic address is available. Then a database is accessed to associate spatial polygons that represent the geographic boundaries of the 6000+ PSAPs in the nation to given latitude and longitude information extracted from the emergency call. The combination of these two important features together result in an accurate and precise “just-in-time” PSAP selection for the caller.
