Abstract

A system and method for determining the historical density of 911 calls from wireless devices. This determination is made over a certain geographical area for a statistically significant amount of time. Once the historical density of these wireless 911 calls has been determined, further determining the most efficient routing of future 911 calls in order to improve the delivery of the wireless 911 call to the responding emergency service provider. The system and the method further provides a method for use by public safety officials, communication providers and other governmental or private entities to manage and control approval and actual changes to the routing of wireless 911 calls.

Claims

1. A method for determining routing of telephone calls from wireless devices to a 911 system, the method operable on a computer system, the method comprising:

receiving 911 wireless call data, the 911 wireless call data comprising location information related to the geographic location of an origin of a telephone call, and comprising sector information related to an antenna sector which processed the telephone call;

determining a jurisdiction corresponding to the geographic location of the origin of the telephone call;

determining a number of telephone calls that originate in different jurisdictions over a predetermined period of time; and

for at least one antenna sector, determining a routing of future telephone calls received by the at least one antenna sector by determining if the number of telephone calls originating in a particular jurisdiction exceeds a predetermined threshold.

2. The method according to claim 1, further comprising:

generating a representation of the geographic location of the origin of a plurality of telephone calls; and

displaying the representation to a user.

3. The method according to claim 2, wherein the representation is a geographic map with the location of the origin of the plurality of telephone calls plotted thereon.

4. The method according to claim 3, wherein boundaries different jurisdictions are displayed on the geographic map.

5. The method according to claim 2, wherein the representation includes at least one table describing at least one of the determinations.

6. The method according to claim 1, wherein the 911 wireless call data further comprises a length of time of the telephone call.

7. The method according to claim 1, wherein telephone calls were originally routed to an original Public Safety Answering Point (PSAP) and it is determined that more than the predetermined threshold number of telephone calls originated in a jurisdiction of a new PSAP.

8. The method according to claim 7, further comprising instructing the operator of the at least one antenna sector to route all future telephone calls to the new PSAP.

9. The method according to claim 7, further comprising determining a number of telephone calls transferred by the original PSAP to the new PSAP.

10. The method according to claim 7, further comprising determining a projected number of new telephone calls expected to be routed to the new PSAP.

11. The method according to claim 1, further comprising determining if the antenna sector is in a buffer zone of a highway.

12. The method according to claim 1, further comprising determining if a coverage area of the antenna sector includes a highway.

13. The method according to claim 12, further comprising determining a number of telephone calls originating in a buffer zone of the highway and determining a number of telephone calls originating out of the buffer zone.

14. The method according to claim 1, wherein the predetermined threshold is 51% of all the telephone calls in the predetermined period of time.

15. A method for tracking decisions for routing of telephone calls from wireless devices to a 911 system, the method operable on a computer system, the method comprising:

receiving 911 wireless call data, the 911 wireless call data comprising location information related to the geographical location of the origin of the telephone call, and comprising sector information related to an antenna sector which processed the telephone call;

determining a jurisdiction corresponding to the geographic location of the origin of the telephone call;

determining a number of telephone calls that originate in different jurisdictions over a predetermined period of time;

for at least one antenna sector, determining if the number of telephone calls originating in a particular jurisdiction exceeds a predetermined threshold,

providing a interface for use by at least one decision maker;

displaying at least one of the determinations to the decision maker; and

receiving a decision from the at least one decision maker regarding the routing of telephone calls in the at least one sector.

16. The method according to claim 15, further comprising executing additional determinations at the request of the at least one decision maker.

17. The method according to claim 15, wherein there a plurality of decision makers, each one representing a different jurisdiction in which a telephone call originated, the method further comprising receiving a decision from each of the decision makers.

18. The method according to claim 15, further comprising determining if the number of telephone calls originating in a particular jurisdiction exceeds the predetermined threshold for a plurality of antenna sectors.

19. A computer readable medium having program code stored thereon which, when run on a computer, causes the computer to determining routing of telephone calls from wireless devices to a 911 system comprising:

receiving 911 wireless call data, the 911 wireless call data comprising location information related to the geographical location of an origin of a telephone call, and comprising sector information related to an antenna sector which processed the telephone call;

determining a jurisdiction corresponding to the geographic location of the origin of the telephone call;

determining a number of telephone calls that originate in different jurisdictions over a predetermined period of time; and

for at least one antenna sector, determining the routing of future telephone calls received by the at least one antenna sector by determining if the number of telephone calls originating in a particular jurisdiction exceeds a predetermined threshold.

20. A system for determining routing of telephone calls from wireless devices to a 911 system, the system comprising

an input/receiving section that receives 911 wireless call data, the 911 wireless call data comprising location information related to the geographical location of the origin of the telephone call, and comprising sector information related to an antenna sector which processed the telephone call;

a data processing and analysis section coupled to the input/receiving section, the data processing and analysis section;

determining a jurisdiction corresponding to the geographic location of the origin of the telephone call,

determining a number of telephone calls that originate in different jurisdictions over a predetermined period of time, and

for at least one antenna sector, determining the routing of future telephone calls by determining if the number of telephone calls originating in a particular jurisdiction exceeds a predetermined threshold; and

an output section coupled to the data processing and analysis section, the output section outputting a graphical representation of at least one of the determinations of the data processing and analysis section.
