Abstract

A system and method for providing information associated with public safety answering points may include storing a set of records including information associated with a plurality of PSAPs, each record may include (i) an identifier indicative of a PSAP available to service emergency communications, (ii) at least one cell code identifier indicative of cell sites in which the associated PSAP services, and (iii) at least one network address capable of receiving certain emergency data message types. In response to receiving a request, a PSAP local to a wireless communications device of a user who sent an emergency data message may be identified, and a network address associated with the identified local PSAP may be provided.

Claims

1. A method for routing a call from a communications device to a public safety answering point (PSAP), the method comprising:

receiving the call at an emergency data message router;

determining a location of the communications device;

determining an emergency data message type associated with the call;

determining, using a processor, a plurality of public safety answering points (PSAPs) capable of receiving the emergency data message type associated with the call;

selecting a closest public safety answering point from the plurality of public safety answering points capable of receiving the emergency data message type associated with the call; and

routing the call to the selected public safety answering point.

2. The method of claim 1, wherein determining the plurality of public safety answering points capable of receiving the emergency data message type associated with the call comprises accessing a database containing a set of records including information associated with the plurality of PSAPs, each record including:

an identifier indicative of a PSAP available to service emergency communications;

at least one cell code identifier indicative of cell sites in which the PSAP services; and

at least one network address capable of receiving certain emergency data message types.

3. The method of claim 1, wherein receiving the call includes receiving a cell code identifier identifying a cell tower in communication with the communications device.

4. The method of claim 1, wherein receiving the call includes receiving an identifier indicative of the emergency data message type being a text message.

5. The method of claim 1, wherein determining the plurality of public safety answering points capable of receiving the emergency data message type associated with the call includes identifying at least one PSAP having a matching exchange code with an exchange code of the mobile directory number of the communications device.

6. The method of claim 1, wherein selecting a closest public safety answering point from the plurality of public safety answering points capable of receiving the emergency data message type associated with the call includes using at least one cell code identifier to identify a PSAP local to the communications device.

7. The method of claim 1, wherein the emergency data message type is an email.

8. The method of claim 1, wherein the emergency data message type is an instant message.

9. The method of claim 1, wherein the emergency data message type is an image file.

10. The method of claim 1, wherein the emergency data message type is a video file.

11. A system for routing a call from a communications device to a public safety answering point (PSAP), the system comprising:

a network communication interface for receiving the call; and

a processor configured to;

determine a location of the communications device;

determine an emergency data message type associated with the call;

determine a plurality of public safety answering points (PSAPs) capable of receiving the emergency data message type associated with the call;

select a closest public safety answering point from the plurality of public safety answering points capable of receiving the emergency data message type associated with the call; and

route the call to the selected public safety answering point.

12. The system of claim 11, wherein determining the plurality of public safety answering points capable of receiving the emergency data message type associated with the call comprises accessing a database containing a set of records including information associated with the plurality of PSAPs, each record including:

an identifier indicative of a PSAP available to service emergency communications;

at least one cell code identifier indicative of cell sites in which the PSAP services; and

at least one network address capable of receiving certain emergency data message types.

13. The system of claim 11, wherein receiving the call includes receiving a cell code identifier identifying a cell tower in communication with the communications device.

14. The system of claim 11, wherein receiving the call includes receiving an identifier indicative of the emergency data message type being a text message.

15. The system of claim 11, wherein determining the plurality of public safety answering points capable of receiving the emergency data message type associated with the call includes identifying at least one PSAP having a matching exchange code with an exchange code of the mobile directory number of the communications device.

16. The system of claim 11, wherein selecting a closest public safety answering point from the plurality of public safety answering points capable of receiving the emergency data message type associated with the call includes using at least one cell code identifier to identify a PSAP local to the communications device.

17. The system of claim 11, wherein the emergency data message type is an email.

18. The system of claim 11, wherein the emergency data message type is an instant message.

19. The system of claim 11, wherein the emergency data message type is an image file or a video file.

20. A machine-readable tangible and non-transitory medium having information for routing a call from a communications device to a public safety answering point (PSAP), wherein the information, when read by the machine, causes the machine to perform the following:

determine a location of the communications device;

determine an emergency data message type associated with the call;

determine a plurality of public safety answering points (PSAPs) capable of receiving the

emergency data message type associated with the call;

select a closest public safety answering point from the plurality of public safety answering

points capable of receiving the emergency data message type associated with the call;

and

route the call to the selected public safety answering point.
