Abstract

A system and method for numbering plan area (NPA) split processing is disclosed. In one implementation, a query is received during a permissive dialing period. The query comprises a destination location that is associated with a first NPA. It is determined whether a first call processing record identifies a service that is NPA sensitive. The first call processing record is associated with a destination location that is undergoing a NPA split. The first call processing record is identified by the destination location and the destination location is associated with a first NPA. A second call processing record is then used for processing in place of the first call processing record when the first call processing record identifies a service that is NPA sensitive. The second call processing record is associated with the destination location that is undergoing an NPA split. The second call processing record is identified by the destination location and the destination location is associated with a second NPA.

Claims

1. A method for numbering plan area (NPA) split processing, the method comprising:

receiving a query during a permissive dialing period, the query comprising a destination location, the destination location associated with a first NPA;

determining whether a first call processing record identifies a service that is NPA sensitive, the first call processing record associated with a destination location undergoing an NPA split and identified by the destination location, the destination location associated with the first NPA; and

using a second call processing record in place of the first call processing record when the first call processing record identifies a service that is NPA sensitive, the second call processing record associated with the destination location undergoing an NPA split and identified by the destination location, the destination location associated with a second NPA.

2. The method of claim 1 further comprising:

using the first call processing record when the first call processing record does not identify a service that is NPA sensitive.

3. The method of claim 1, wherein a service is NPA sensitive if a change made to either but not both of the first and second call processing records during the permissive dialing period will result in improper service execution.

4. A method for numbering plan area (NPA) split processing, the method comprising:

receiving a query during a permissive dialing period, the query comprising a destination location comprising an NPA undergoing an NPA split;

assigning the destination location to a call variable;

retrieving a call processing record identified by the call variable, wherein the call processing record identifies a service;

determining whether the service is NPA sensitive; and

changing the NPA in the call variable to a new NPA when the service is NPA sensitive.

5. The method of claim 4, further comprising:

retrieving a second call processing record identified by the call variable with the new NPA; and

using the second call processing record instead of the first-mentioned call processing record.

6. The method of claim 4 further comprising:

determining whether the destination location assigned to the call variable is stored in a storage location; and

determining whether the destination location with the new NPA is stored in the storage location when the destination location assigned to the call variable is not stored in the storage location.

7. The method of claim 4, wherein the service is NPA sensitive if a duplicate copy of the call processing record exists during the permissive dialing period and a change made to either but not both of the call processing record and the duplicate copy of the call processing record during the permissive dialing period will result in improper service execution.

8. The method of claim 4, wherein the service is NPA sensitive if the service checks a storage location storing one but not both of the following:

the destination location comprising the NPA undergoing the NPA split and the destination location comprising the new NPA.

9. The method of claim 4, further comprising:

identifying the new NPA from a table correlating the NPA undergoing the NPA split with the new NPA.

10. The method of claim 4, further comprising:

determining that the query was sent during the permissive dialing period.

11. The method of claim 10, wherein the determination that the query was sent to the service control point during the permissive dialing period is made by consulting a table correlating the NPA undergoing the NPA split, the new NPA, and a date range for the permissive dialing period.

12. A method for numbering plan area (NPA) split processing, the method comprising:

receiving a query during a permissive dialing period, the query comprising a destination location undergoing an NPA split;

changing data in a subscriber'"'"'s call processing record identified by a destination location that is associated with a first NPA when the query is received to change a first profile management call processing record;

changing data in a subscriber'"'"'s call processing record identified by the destination location that is associated with a second NPA when the query is received to change a second profile management call processing record;

wherein the first profile management call processing record is associated with a service that is NPA sensitive and the second profile management call processing record is associated with a service that is not NPA sensitive.

13. The method of claim 12, wherein the service is NPA sensitive if a duplicate copy of the first call processing record exists during the permissive dialing period and a change made to either but not both of the first call processing record and the duplicate copy of the first call processing record during the permissive dialing period will result in improper service execution.

14. The method of claim 12, wherein the service is NPA sensitive if the service checks a storage location storing one but not both of the following:

a destination location that is associated with the first NPA and the destination location that is associated with the second NPA.

15. The method of claim 12, further comprising:

identifying the second NPA from a table correlating the first NPA with the second NPA.

16. The method of claim 12 further comprising:

determining that the query was sent during the permissive dialing period.

17. The method of claim 16, wherein the determination that the query was sent during the permissive dialing period is made by consulting a table correlating the first NPA, the second NPA, and a date range for the permissive dialing period.

18. A computer-readable storage medium comprising a set of instructions for numbering plan area (NPA) split processing, the set of instructions to direct a processor to perform acts of:

receiving a query during a permissive dialing period, the query comprising a destination location, the destination location associated with a first NPA;

determining whether a first call processing record identifies a service that is NPA sensitive, the first call processing record associated with a destination location undergoing an NPA split and identified by the destination location, the destination location associated with the first NPA; and

using a second call processing record in place of the first call processing record when the first call processing record identifies a service that is NPA sensitive, the second call processing record associated with the destination location undergoing an NPA split and identified by the destination location, the destination location associated with a second NPA.

19. A system for numbering plan area (NPA) split processing, the system comprising:

a network element in communication with at least a second network element, the network element operative to receive a query comprising a destination location from at least the second network element, to access at least a first and second call processing record, and to NPA split processing;

wherein the first and second call processing records are associated with a destination location undergoing an NPA split, the first call processing record identified by a destination location that is associated with a first NPA and the second call processing record identified by the destination location that is associated with the second NPA;

wherein the network element accesses the first call processing record to determine whether the first call processing record identifies a service that is NPA sensitive and uses the second call processing record in place of the first call processing record when the first cal processing record identifies a service that is NPA sensitive.

20. The system of claim 19, wherein a service is NPA sensitive if a change made to either but not both of the first and second call processing records during the permissive dialing period will result in improper service execution.
