Identification of static position witnesses to a PSAP emergency
When a PSAP receives a call from a cellular telephone in reference to an emergent event, the speed and quality of the response may be improved by the cellular service provider's provision to the PSAP of information that includes the geographic location of the caller's phone. In a typical scenario, in which the call is from a GPS-equipped phone, the GPS coordinates of the phone may be echoed back to the PSAP in response to a specialized open “ping” request from the service provider. Of particular advantage to this approach is that GPS ping requests typically work regardless of whether a call is in progress, as long as the phone is turned on.
1. A method to prioritize telephone calls comprising:
determining, by a computer processor, a location of an emergent event;
receiving two or more telephone calls by the computer processor at a PSAP (Public Safety Answering Point), and for each call, and before at least one call is answered;
determining for each call, by the computer processor, whether or not a caller is proximate to a determined location of the emergent event and moving; and
based on the determined caller proximity and movement,
resequencing, by the computer processor, a call wait queue prioritizing at least one of the two or more calls that is proximate to a determined location of the emergent event and stationary relative to the determined location of the emergent event over at least one other call that is moving relative to a determined location of the emergent event; and
obtaining, by the computer processor, one or more of history information, cell tower registration information and triangulation information.
2. The method of claim 1 , further comprising performing a ping request for each received call.
3. The method of claim 1 , further comprising determining, by the computer processor, if the calls are originating from approximately a same location as the determined location of the emergent event.
4. The method of claim 1 , further comprising determining, by the computer processor, if there are more PSAP agents than calls.
5. The method of claim 1 , further comprising the computer processor presenting all of the two or more calls for answering by an agent.
6. The method of claim 1 , further comprising establishing, by the computer processor, a new location for a new emergent event.
7. The method of claim 1 , wherein one or more components of a computer system perform the determining, receiving, and resequencing steps.
8. The system of claim 1 , wherein statistical information is considered to determine if a cluster of received calls are for an emergent event.
9. A non-transitory computer-readable information storage media having stored thereon instructions, that when executed by a processor, cause to be performed the steps of claim 1 .
10. A system that prioritizes calls comprising:
a PSAP (Public Safety Answering Point) server, wherein the PSAP server is configured to:
determine a location of an emergent event;
receive two or more telephone calls, and for each call, and before at least one call is answered, determine whether or not a caller is proximate to a determined location of the emergent event and moving; and
based on the determined caller proximity and movement, resequence a call wait queue prioritizing at least one of the two or more telephone calls that is proximate to the emergent event and stationary relative to the determined location of the emergent event over at least one other telephone call that is moving relative to a determined location of the emergent event; and
obtain, one or more of history information, cell tower registration information, and triangulation information.
11. The system of claim 10 , further comprising a ping module that performs a ping request for each received call.
12. The system of claim 10 , wherein two or more of history information, cell tower registration information and triangulation information are used for the determining of whether a caller is moving.
13. The system of claim 10 , further comprising an event proximity determination module that determines if the two or more calls are originating from approximately a same location as a determined location of the emergent event.
14. The system of claim 10 , wherein the call priority module further determines if there are more PSAP agents than calls.
15. The system of claim 10 , wherein PSAP agents answer all of the two or more calls.
16. The system of claim 10 , wherein a new location is established for a new emergent event.
