Abstract

Master Street Address Guide (MSAG)-validated street address data is correlated with real-world geographic (e.g., latitude/longitude) data. Conventional MSAG-validated street address data is processed, or geocoded, into an additional (or integrated) database that associates latitude/longitude information with a particular entry in the existing MSAG-validated database. The association of the lat/lon data may be direct, or indirect using link ID or other unique tags indicating a particular entry in the MSAG-validated database. The geocoding need be performed only once by a service provider, e.g., as part of the deployment of an emergency service system. In this way, the closest public service answering point (PSAP) to a given latitude/longitude position of a wireless or VoIP device may be determined quickly, providing emergency services with the smallest possible reliable response time.

Claims

1. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude location of a wireless device;

determining a unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID; and

wherein said unique road link ID is associated with a two-dimensional area of road including a range of latitude coordinates and a range of longitudinal coordinates, said current lat/lon location falling within said range of latitude coordinates and within said range of longitudinal coordinates.

2. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude location of a wireless device;

determining a unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID; and

wherein said given length of road is divided at crossroads.

3. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude location of a wireless device;

determining a unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID; and

wherein said given length of road is divided at driveways.

4. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude location of a wireless device;

determining a unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID; and

wherein said given length of road is divided at locations where street address numbers change.

5. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude location of a wireless device;

determining a unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID; and

associating an emergency services number with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID.

6. A method of mapping a current lat/lon location of a wireless device into a street address, comprising:

obtaining a current latitude/longitude (lat/lon) location of a wireless device;

determining a closest unique road link ID associated with said obtained current lat/lon location; and

returning a street address associated with said unique road link ID;

wherein a given length of road is divided into a plurality of road links each associated with its own unique road link ID.
