Abstract

Efficient telephone number mapping (ENUM) based call routing during area code splits is described. An ENUM domain management component can associate an ENUM domain name with multiple records when a numbering plan area code split links an old area code of a telephone number corresponding to the ENUM domain name with a new area code. An ENUM provisioning component can perform permissive dialing of the old and new area code during ENUM based call routing by utilizing the multiple records.

Claims

1. A system, comprising:

a memory to store computer-executable instructions; and

a processor, communicatively coupled to the memory, that facilitates execution of the computer-executable instructions to perform operations, comprising;

associating first data representing a telephone number mapping domain name with records representing area codes that are assigned to a telephone number corresponding to the telephone number mapping domain name in response to a determination that second data representing a numbering plan area code split relates an old area code of the area codes to a new area code of the area codes;

facilitating, based on the records, use of the old area code and the new area code associated with call routing utilizing the first data representing the telephone number mapping domain name;

permitting, for a predetermined period of time, dialing of the old area code and the new area code to facilitate connection to a telephone number mapping communication termination point device;

relating the first data representing the telephone number mapping domain name to a record of the records based on the predetermined period of time; and

preventing a modification of the first data representing the telephone number mapping domain name during the predetermined period of time.

2. The system of claim 1, wherein the operations further comprise:

creating a first telephone number mapping domain name record of the records that is associated with the old area code; and

creating a second telephone number mapping domain name record of the records that is associated with the new area code, wherein the second telephone number mapping domain name record is different than the first telephone number mapping domain name record.

3. The system of claim 1, wherein the operations further comprise:

relating the new area code to the old area code using the second data after the first data is associated with the records.

4. The system of claim 1, wherein the operations further comprise:

disassociating the first data representing the telephone number mapping domain name from one of the records that is associated with the old area code in response to a determination that a permissive dialing period representing the predetermined period of time has ended.

5. The system of claim 1, wherein the operations further comprise:

disassociating the first data representing the telephone number mapping domain name from one of the records that is associated with the old area code in response to a determination that the one of the records has been removed from a data store.

6. The system of claim 1, wherein the operations further comprise:

preventing storage of one of the records related to the new area code before a permissive dialing period representing the predetermined period of time begins.

7. The system of claim 1, wherein the operations further comprise:

preventing storage of one of the records related to the old area code after a permissive dialing period representing the predetermined period of time begins.

8. The system of claim 1, wherein the operations further comprise:

deleting one of the records from a data store that is associated with the old area code.

9. The system of claim 1, wherein the operations further comprise:

preventing storage of one of the records before a permissive dialing period representing the predetermined period of time in response to a determination that the telephone number comprises the new area code; and

preventing storage of the one of the records within the permissive dialing period in response to a determination that the telephone number comprises the old area code.

10. The system of claim 1, wherein the operations further comprise:

preventing a change of the first data representing the telephone number mapping domain name during a permissive dialing period representing the predetermined period of time.

11. The system of claim 1, wherein the operations further comprise:

eliminating one of the records after a permissive dialing period representing the predetermined period of time in response to a determination that the telephone number comprises the old area code.

12. The system of claim 1, wherein the operations further comprise:

routing a telephone number mapping based call to a cellular based endpoint.

13. The system of claim 1, wherein the operations further comprise:

storing the first data representing the telephone number mapping domain name in a domain name system data store.

14. A method, comprising:

creating, by a system comprising a processor, a first record and a second record, wherein the first record represents a first area code that is assigned to a telephone number associated with a telephone number mapping domain name, and wherein the second record represents a second area code that is assigned to the telephone number;

linking, by the system utilizing the first record and the second record, the first area code and the second area code to a telephone number mapping communication termination point device;

in response to permitting, for a predetermined period of time, dialing of the first area code and the second area code, facilitating, by the system based on the first area code and the second area code, directing a call to the telephone number mapping communication termination point device;

relating, by the system, the first record to the second record based on the predetermined period of time; and

preventing, by the system, a change of data representing the telephone number mapping domain name during a permissive dialing period representing the predetermined period of time.

15. The method of claim 14, further comprising:

disassociating, by the system, the data representing the telephone number mapping domain name from the first record in response to a determination that the permissive dialing period has ended.

16. The method of claim 14, further comprising:

preventing, by the system, storage of the first record before the permissive dialing period begins.

17. A tangible computer readable storage medium comprising computer executable instructions that, in response to execution, cause a computing system comprising a processor to perform operations, comprising:

creating different records referencing data representing a telephone number mapping domain name that is associated with a telephone number and different area codes that are associated with the telephone number;

in response to permitting, for a predetermined period of time, dialing of the call using a first area code of the different area codes and a second area code of the different area codes, facilitating routing, based on the first area code and the second area code, a call to a telephone communication mapping device utilizing the different records;

relating, based on the predetermined period of time, a first record of the different records associated with the first area code and a second record of the different records associated with the second area code; and

preventing a modification of the data representing the telephone number mapping domain name during the predetermined period of time.

18. The tangible computer readable storage medium of claim 17, wherein the operations further comprise:

disassociating the data from the first record in response to a determination that a permissive dialing period representing the predetermined period of time has ended.

19. The tangible computer readable storage medium of claim 17, wherein the operations further comprise:

preventing storage of the first record before a permissive dialing period representing the predetermined period of time begins.

20. The tangible computer readable storage medium of claim 17, wherein the operations further comprise:

eliminating the first record after a permissive dialing period representing the predetermined period of time, wherein the first area code is older than the second area code.
