Abstract

A method of porting a wireless terminal'"'"'s directory number from one wireless service provider to another is disclosed. One illustrative embodiment involves creating a temporary pointer in the recipient wireless service provider'"'"'s Home Location Register that, during the inchoate porting process, directs a call for the directory number to the donor wireless service provider for completion in well-known fashion. When the porting process is complete, the temporary pointer is deactivated and call processing is completed by the recipient wireless service provider in well-known fashion.

Claims

1. A method of porting a directory number from a donor system to a recipient system, said method comprising:

creating a home location register record in a home location register associated with said recipient system for said directory number, which home location register record comprises a status field and a location routing number field;

populating said status field as inactive and said location routing number field with a first location routing number that is associated with said donor system; and

routine an incoming call that is associated with said directory number based on said first location routing number when said status field is populated as inactive.

2. The method of claim 1 further comprising the step of changing a mobile station identification of a wireless terminal associated with said directory number.

3. The method of claim 1 further comprising the step of transmitting an update request to a number portability administrative center, which update associates a directory number with a second location routing number that is associated with said recipient system.

4. The method of claim 3 further comprising the step of receiving from said number portability administrative center an update that associates said directory number with said second location routing number.

5. The method of claim 1 further comprising the step of transmitting a message to said donor system that indicates that said directory number is being ported to said recipient system.

6. The method of claim 1 further comprising the step of transmitting a message to said donor system that requests that said donor system delete a record in a second home location register associated with said directory number.

7. The method of claim 1 further comprising the step of populating said status field to indicate that said first home location register record is active.

8. A method of porting a directory number from a donor system to a recipient system, said method comprising:

transmitting an update request to a number portability administrative center, which update associates a directory number with a location routing number that is associated with said recipient system;

creating a home location register record in a home location register associated with said recipient system for said directory number, which home location register record comprises a status field and a location routing number field; and

routing an incoming call that is associated with said directory number based on a datum in said location routing number field when said status field is populated as inactive.

9. The method of claim 8 further comprising the step of populating said status field to indicate that said first home location register record is active.

10. The method of claim 8 further comprising the step of changing a mobile station identification of a wireless terminal associated with said directory number.

11. The method of claim 8 further comprising the step of receiving from said number portability administrative center an update that associates said directory number with said second location routing number.

12. The method of claim 8 further comprising the step of transmitting a message to said donor system that indicates that said directory number is being ported to said recipient system.

13. The method of claim 8 further comprising the step of transmitting a message to said donor system that requests that said donor system delete a record in a second home location register associated with said directory number.

14. A method of porting a directory number from a donor system to a recipient system, said method comprising:

creating a home location register record in a home location register associated with said recipient system for said directory number, which home location register record comprises a status field and a location routing number field;

routine an incoming call that is associated with said directory number based on a datum in said location routing number field when said status field is populated as inactive; and

transmitting a message to said donor system that requests that said donor system delete a record in a second home location register associated with said directory number.

15. The method of claim 14 further comprising the step of populating said status field to indicate that said first home location register record is active.

16. The method of claim 14 further comprising the step of changing a mobile station identification of a wireless terminal associated with said directory number.

17. The method of claim 14 further comprising the step of receiving from said number portability administrative center an update that associates said directory number with said second location routing number.

18. The method of claim 14 further comprising the step of transmitting a message to said donor system that indicates that said directory number is being ported to said recipient system.
