Abstract

Enhanced services, such as call restriction, call forwarding, anonymous call rejection, and proprietary services, may interfere with an emergency callback potentially preventing the callback from reaching the intended destination. Systems and methods for processing emergency calls to eliminate emergency callback failure in response to an emergency call being disconnected are provided herein.

Claims

1. A method, comprising:

receiving, from an application executed on a mobile communication device, information relating to an emergency call to a public safety answering point;

determining, by a system, based on a query of a database, whether a call-blocking service is activated in association with the mobile communication device;

generating a request for overriding the call-blocking service for a pre-determined time period responsive to the determining that the call-blocking service is activated in association with the mobile communication device; and

initiating transmission of the request for overriding the call-blocking service to allow connection of an emergency callback between the public safety answering point and the mobile communication device during the pre-determined time period,

wherein the pre-determined time period is based upon an average time for wireless emergency calls calculated by the system.

2. The method of claim 1, wherein the information received from the application executed on the mobile communication device comprises a first information of the mobile communication device that made the emergency call.

3. The method of claim 2, wherein:

the first information comprises a customer account information; and

the method further comprises querying the database based on the customer account information.

4. The method of claim 1, wherein the transmission of the request for overriding the call-blocking service is initiated to allow the connection for the pre-determined time period being associated with a temporary override.

5. The method of claim 1, wherein initiating transmission of the request comprises initiating transmission of the request to a remote device that controls the call-blocking service.

6. The method of claim 1, further comprising:

receiving, from the public safety answering point, periodic reports on wireless call logs to the public safety answering point; and

calculating, by the processor, the average time based upon the periodic reports on the wireless call logs.

7. A system, comprising:

a processor; and

a memory having stored thereon instructions that, when executed by the processor, cause the system to;

receive, from an application executed on a mobile communication device, information relating to an emergency call to a public safety answering point;

determine, based on a query of a database, whether a call-blocking service is activated in association with the mobile communication device;

generate a request for overriding the call-blocking service for a pre-determined time period responsive to determining that the call-blocking service is activated in association with the mobile communication device; and

initiate transmission of the request for overriding the call-blocking service to allow connection of an emergency callback between the public safety answering point and the mobile communication device during the pre-determined time period,

wherein the pre-determined time period is based upon an average time for wireless emergency calls calculated by the processor.

8. The system of claim 7, wherein the information received from the application executed on the mobile communication device comprises a first information of the mobile communication device that made the emergency call.

9. The system of claim 8, wherein:

the first information comprises a user account information; and

the memory further has stored thereon instructions which, when executed by the processor, cause the processor to query the database based on the customer account information.

10. The system of claim 7, wherein the transmission of the request for overriding the call-blocking service is initiated to allow the connection for the pre-determined time period being associated with a temporary override.

11. The system of claim 7, wherein initiating transmission of the request comprises initiating transmission of the request to a remote device that controls the call-blocking feature.

12. The system of claim 7, wherein the first information comprises a mobile station international ISDN number.

13. The system of claim 7, wherein the instructions further cause the processor to:

receive, from the public safety answering point, periodic reports on wireless call logs to the public safety answering point; and

calculate the average time based upon the periodic reports on the wireless call logs.

14. The system of claim 8, wherein the first information comprises a mobile station international ISDN number.

15. A computer-readable storage device comprising non-transitory computer-readable instructions that, when executed by a processor, cause the processor to:

receive, from an application executed on a mobile communication device, information relating to an emergency call to a public safety answering point;

determine, based on a query of a database, whether a call-blocking service is activated in association with the mobile communication device;

generate, responsive to determining that the call-blocking service is activated in association with the mobile communication device, a request for overriding the call-blocking service for a pre-determined time period; and

initiate transmission of the request for overriding the call-blocking service to allow connection of an emergency callback between the public safety answering point and the mobile communication device during the pre-determined time period,

wherein the pre-determined time period is based upon an average time for wireless emergency calls calculated by the processor.

16. The computer-readable storage device of claim 15, wherein the information received from the application executed on the mobile communication device comprises a first information of the mobile communication device that made the emergency call.

17. The computer-readable storage device of claim 15, wherein the transmission of the request for overriding the call-blocking service is initiated to allow the connection for the pre-determined time period being associated with a temporary override.

18. The computer-readable storage device of claim 15, wherein initiating transmission of the request comprises initiating transmission of the request to a remote device that controls the call-blocking feature.

19. The computer-readable storage device of claim 15, wherein the instructions further cause the processor to:

receive, from the public safety answering point, periodic reports on wireless call logs to the public safety answering point; and

calculate the average time based upon the periodic reports on the wireless call logs.

20. The computer-readable storage device of claim 16, wherein the first information comprises a mobile station international ISDN number.
