Abstract

Determining if non-voice emergency services (NOVES) are available is accomplished via an indicator provided via a control channel and/or via a query to a network entity. For example, a NOVES indicator can be provided, via a control channel message, to a communications device, indicating whether non-voice emergency services (NOVES) are available or not available. Additionally, capabilities of public safety answering points (PSAPs) providing NOVES can be included. For example, the indicator can include information as to whether an identified PSAP can receive a text based emergency message, an emergency message comprising a image, and emergency message comprising audio, and/or an emergency message comprising video. In another example configuration, a communications device can query a communications network to determine the availability of NOVES and PSAP capabilities. A response to the query can include an indication as to whether non-voice services are available, and, if appropriate, the types of NOVES services available.

Claims

1. An apparatus comprising:

a processor; and

memory coupled to the processor, the memory comprising at least one executable instruction that when executed by the processor causes the processor to effectuate operations comprising;

receiving a query to determine an availability of non-voice based emergency messaging;

determining if the query comprises at least one;

of an indication of a cellular site that received the query;

or

an indication of a location from which the query was provided; and

when it is determined that the query comprises an indication of a cellular site that received the query;

determining a region covered by the cellular site;

identifying a public safety answering point (PSAP) that is assigned to handle the region; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the region; and

when it is determined that the query comprises an indication of a location from which the query was provided;

identifying a PSAP that is assigned to handle the location; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the location; and

providing a response to the query, the response comprising an indication of availability of non-voice based emergency messaging.

2. The apparatus of claim 1, wherein the apparatus comprises an entity in a wireless communications network.

3. The apparatus of claim 1, the operations further comprising:

when the query comprises an indication of a cellular site that received the query;

providing a query to a first network entity to determine a region covered by the cellular site; and

providing a query to a second network entity to identify the PSAP assigned to handle the region.

4. The apparatus of claim 1, the operations further comprising:

when the query comprises an indication of a location from which the query was provided, providing a query to a network entity to identify the PSAP assigned to handle the location.

5. The apparatus of claim 1, the operations further comprising:

determining non-voice message capabilities of the identified PSAP.

6. The apparatus of claim 5, wherein:

the capabilities comprise at least one of;

the identified PSAP being able to receive at least one of a text based emergency message;

an emergency message comprising an image;

or

an emergency message comprising video.

7. A method comprising:

receiving a query to determine an availability of non-voice based emergency messaging;

determining if the query comprises at least one;

of an indication of a cellular site that received the query;

or

an indication of a location from which the query was provided;

when the query comprises an indication of a cellular site that received the query;

determining a region covered by the cellular site;

identifying a public safety answering point (PSAP) that is assigned to handle the region; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the region; and

when the query comprises an indication of a location from which the query was provided;

identifying a PSAP that is assigned to handle the location; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the location; and

providing a response to the query, the response comprising an indication of availability of non-voice based emergency messaging.

8. The method of claim 7, wherein the method is performed via an entity in a wireless communications network.

9. The method of claim 7, further comprising:

when the query comprises an indication of a cellular site that received the query;

providing a query to a first network entity to determine a region covered by the cellular site; and

providing a query to a second network entity to identify the PSAP assigned to handle the region.

10. The method of claim 7, further comprising:

when the query comprises an indication of a location from which the query was provided, providing a query to a network entity to identify the PSAP assigned to handle the location.

11. The method of claim 7, further comprising:

determining non-voice message capabilities of the identified PSAP.

12. The method of claim 11, wherein the capabilities comprise the identified PSAP being able to receive at least one of a text based emergency message, an emergency message comprising an image, or an emergency message comprising video.

13. A computer-readable storage medium comprising at least one executable instruction that when executed by a processor cause the processor to effectuate operation comprising:

receiving a query to determine an availability of non-voice based emergency messaging;

determining if the query comprises at least one;

of an indication of a cellular site that received the query;

or

an indication of a location from which the query was provided;

when the query comprises an indication of a cellular site that received the query;

determining a region covered by the cellular site;

identifying a public safety answering point (PSAP) that is assigned to handle the region; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the region; and

when the query comprises an indication of a location from which the query was provided;

identifying a PSAP that is assigned to handle the location; and

determining availability of non-voice based emergency messaging of the identified PSAP assigned to handle the location; and

providing a response to the query, the response comprising an indication of availability of non-voice based emergency messaging.

14. The computer-readable storage medium of claim 13, the operations further comprising:

when the query comprises an indication of a cellular site that received the query;

providing a query to a first network entity to determine a region covered by the cellular site; and

providing a query to a second network entity to identify the PSAP assigned to handle the region.

15. The computer-readable storage medium of claim 13, the operations further comprising:

when the query comprises an indication of a location from which the query was provided, providing a query to a network entity to identify the PSAP assigned to handle the location.

16. The computer-readable storage medium of claim 13, the operations further comprising:

determining non-voice message capabilities of the identified PSAP.

17. The computer-readable storage medium of claim 16, wherein:

the capabilities comprise at least one of;

the identified PSAP being able to receive at least one of a text based emergency message;

an emergency message comprising an image;

or

an emergency message comprising video.
