Abstract

A system receives an emergency call, a local exchange carrier (LEC) charge number, and Calling Party Number (CPN) from a user device, and overrides the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes. The system also determines the ANI of the user device based on the CPN, receives an address associated with the user device based on the ANI, and provides the emergency call and the address to a Public Safety Answering Point (PSAP).

Claims

1. A method implemented by a computing device, the method comprising:

receiving, by the computing device, an emergency call, a local exchange carrier (LEC) charge number, and a Calling Party Number (CPN) from a user device;

providing, in a switch table, a customer configuration option;

implementing, by the computing device, the customer configuration option to override the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes;

determining, by the computing device, the ANI of the user device based on the CPN;

receiving, by the computing device, an address associated with the user device based on the ANI; and

providing, by the computing device, the emergency call and the address to a Public Safety Answering Point (PSAP).

2. The method of claim 1, further comprising:

providing the ANI to an Automatic Location Identification (ALI) database that determines the address associated with the user device based on the ANI.

3. The method of claim 1, further comprising:

determining the PSAP based on the address associated with the user device.

4. The method of claim 1, further comprising:

providing the LEC charge number to a billing system that bills a LEC associated with the LEC charge number.

5. A method implemented by a computing device, the method comprising:

receiving, by the computing device, a call, a local exchange carrier (LEC) charge number, and a Calling Party Number (CPN) from a first user device;

determining, by the computing device, whether the call is an emergency call or a call destined for a second user device;

providing, by the computing device, the call to the second user device when the call is determined to be a call destined for the second user device; and

when the call is determined to be an emergency call;

providing, in a switch table, a customer configuration option,

executing, by the computing device, the customer configuration option to override the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes,

determining, by the computing device, the ANI of the first user device based on the CPN,

receiving, by the computing device, an address associated with the first user device based on the ANI, and

providing, by the computing device, the emergency call and the address to a Public Safety Answering Point (PSAP).

6. The method of claim 5, where providing, by the computing device, the call to the second user device comprises one of:

providing the call and the CPN to the second user device when CPN screening is unassociated with the first user device;

or

providing the call to the second user device when CPN screening is associated with the first user device.

7. The method of claim 5, where, when the call is determined to be an emergency call, the method further comprises:

providing the ANI to an Automatic Location Identification (ALI) database that determines the address associated with the first user device based on the ANI.

8. The method of claim 5, where, when the call is determined to be an emergency call, the method further comprises:

determining the PSAP based on the address associated with the first user device.

9. The method of claim 5, further comprising:

providing the LEC charge number to a billing system that bills a LEC associated with the LEC charge number.

10. A device, comprising:

a memory to store;

a plurality of instructions, and

a switch table that includes a customer configuration option; and

a processor to execute instructions in the memory to;

receive an emergency call, a local exchange carrier (LEC) charge number, and a Calling Party Number (CPN) associated with a user device,

execute the customer configuration option to override the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes,

determine the ANI of the user device based on the CPN,

receive a physical address associated with the user device based on the ANI, and

provide the emergency call and the physical address to a Public Safety Answering Point (PSAP).

11. The device of claim 10, where the processor is further to execute instructions in the memory to:

provide the ANI to an Automatic Location Identification (ALI) database that determines the physical address associated with the user device based on the ANI.

12. The device of claim 10, wherein where the processor is further executes to execute instructions in the memory to:

determine the PSAP located a closest distance from the physical address associated with the user device.

13. The device of claim 10, where the processor is further to execute instructions in the memory to:

provide the LEC charge number to a billing system that bills a LEC associated with the LEC charge number.

14. A device, comprising:

a memory to store;

a plurality of instructions, and

a switch table that includes a customer configuration option; and

a processor to execute instructions in the memory to;

receive a call, a local exchange carrier (LEC) charge number, and a Calling Party Number (CPN) associated with a first user device,

determine whether the call is an emergency call or a call destined for a second user device,

provide the call to the second user device when the call is determined to be a call destined for the second user device, and

when the call is determined to be an emergency call;

execute the customer configuration option to override the LEC charge number with the CPN for Automatic Number Identification (ANI) determination purposes,

determine the ANI of the first user device based on the CPN,

receive a physical address associated with the first user device based on the ANI, and

provide the emergency call and the physical address to a Public Safety Answering Point (PSAP).

15. The device of claim 14, where the processor is further to execute instructions in the memory to one of:

provide, when the call is determined to be a call destined for the second user device, the call and the CPN to the second user device when CPN screening is unassociated with the first user device;

or

provide, when the call is determined to be a call destined for the second user device, the call to the second user device when CPN screening is associated with the first user device.

16. The device of claim 14, where the processor is further to execute instructions in the memory to:

provide the ANI to an Automatic Location Identification (ALI) database that determines the physical address associated with the first user device based on the ANI.

17. The device of claim 14, where the processor is further to execute instructions in the memory to:

determine the PSAP located a closest distance from the physical address associated with the first user device.

18. The device of claim 14, where the processor is further to execute instructions in the memory to:

provide the LEC charge number to a billing system that bills a LEC associated with the LEC charge number.
