摘要:
A logic history can be provided for every request or call instance through a distributed computing system that uniquely traces its entire path, end-to-end, in-band within the messaging for the system. The end result is a single true representation of what occurred with no post computational inference. Accordingly, unique logic history codes are not forced across the system. Rather sub-components that are logic history enabled can use codes that have meaning and applicability to itself. Unique logic history codes are not forced across the system, which in practice would be brittle. Rather each sub-component that is logic history enabled can use codes that have meaning and applicability only to itself. This allows the system to be flexible and lets sub-components change and redefine their logic and logic history traces without impacting the rest of the system.

An emergency services key (e.g., ESQK or ESRK) is guaranteed to be available from a limited size ESQK pool, such that an available ESQK is always selected and associated with an ongoing emergency call with no measurable impact to existing calls, even if all ESQK pool members are marked as unavailable. 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”, and information relating to the specific emergency E911 call (“Call Data ID”). 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 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:
A simplified method of encoding information needed to set the NENA 08-001 v2 Result code based on two essential factors that are stored in a data store at runtime. An ESRResponse header is built with two fields created as simple enumerated types: LocationSrc and RoutedOnAlgo. For each emergency call there is one entry in this data store. The first field of the ESRResponse header comprises one of five possible unique values, as does the second field.
摘要:
A technique and apparatus to find an optimal MSAG-valid address in real time given an E9-1-1 caller's civic/postal address. Arrival at an accurate MSAG-valid address selection moves through as many as three well defined MSAG matching steps which may be performed sequentially, or in tandem. The three disclosed MSAG matching techniques include a Simple Match of an MSAG address, a historical data match for an MSAG address, and a pinned MSAG match performed using a commercial location engine.
