Abstract

A system for correcting or updating a mobile identification number in a cellular telephone portion of a telematics unit installed in a vehicle allows service providers to resolve duplicate entries. A wireless service provider stores a triplicate entry in their HLR for cellular telephones associated with a number of telematics unit. The triplicate entry includes a MDN, a MIN, and an ESN. If a telematics unit'"'"'s triplicate entry is an invalid combination, resulting, e.g., in call failure, the system provides an efficient mechanism whereby the service provider can update the MIN of each cellular telephone in one or more telematics units to eliminate duplicate entries.

Claims

1. A method for updating a mobile identification number in a cellular telephone in each of two or more telematics units, the method comprising:

receiving an erroneous registry entry having a first mobile identification number that is not unique in that two or more cellular telephones associated with respective ones of the two or more telematics units share the first mobile identification number such that a first one of the telematics units cannot send and receive calls;

sending a request to a wireless service provider to select a first cellular telephone in the first telematics unit of the two or more telematics units, the first cellular telephone being associated with a first triplicate entry stored in a home location registry for the first cellular telephone, the first triplicate entry including a first mobile directory number, an erroneous mobile identification number, and a first electronic serial number;

sending a request to the wireless service provider to assign a second mobile identification number to the first cellular telephone;

updating the first cellular telephone in the first telematics unit with the second mobile identification number; and

notifying the wireless service provider of the update and requesting the wireless service provider to store the second mobile identification number in the first triplicate entry in the home location registry for the first cellular telephone.

2. The method according to claim 1, the method further comprising requesting the wireless service provider to store a second triplicate entry that includes the first mobile identification number in a second triplicate entry in the home location registry for a second cellular telephone in a second telematics unit.

3. The method according to claim 2, the method further comprising receiving a notification from the wireless service provider of activation of the first cellular phone in the first telematics unit and activation of the second cellular telephone in the second telematics unit.

4. The method according to claim 3, the method further comprising connecting to the first cellular phone in the first telematics unit and the second cellular telephone in the second telematics unit.

5. The method of claim 1 further comprising:

prioritizing updating mobile identification of the two or more cellular telephones of the two or more telematics units based on account status and account type.

6. The method according to claim 5 further comprising prioritizing updating the first mobile identification number of each of the two or more cellular telephones of the two or more telematics units based on a switch activation time stamp.

7. The method according to claim 1 further comprising:

sending a request to the wireless provider to select a second cellular telephone in a second telematics unit of the plurality of telematics units, the second cellular telephone having a second triplicate entry stored in a home location registry for the second cellular telephone, the second triplicate entry including a second mobile directory number, first mobile identification number, and a second electronic serial number;

updating the second cellular phone in the second telematics unit with a second mobile identification number; and

requesting the wireless service provider to store the second mobile identification number in the second triplicate entry in the home location registry for the second cellular telephone for the second telematics unit and to activate the second cellular telephone.

8. The method according to claim 7, the method further comprising:

sending a request to the wireless provider to select a third cellular telephone in a third telematics unit of the plurality of telematics units having a third triplicate entry stored in a home location registry for the third cellular telephone, the third triplicate entry including a third mobile directory number, the first mobile identification number, and a third electronic serial number;

updating the third cellular phone in the third telematics unit with a third mobile identification number; and

requesting the wireless service provider to store the third mobile identification number in the third triplicate entry in the home location registry for the third cellular telephone in the third telematics unit and to activate the third cellular telephone.

9. The method according to claim 8, the method further comprising:

sending a request to the wireless service provider to select a fourth cellular telephone in a fourth telematics unit of the plurality of telematics units having a fourth triplicate entry stored in a home location registry for the fourth cellular telephone, the fourth triplicate entry including a fourth mobile directory number, the first mobile identification number, and a fourth electronic serial number; and

requesting the wireless service provider to store the fourth mobile identification number in the fourth triplicate entry in the home location registry for the fourth cellular telephone in the fourth telematics unit and to activate the fourth cellular telephone.

10. The method according to claim 9, the method further comprising receiving a notification from the wireless service provider of activation of the first cellular phone in the first telematics unit, activation of the second cellular telephone in the second telematics unit, activation of the third cellular telephone in the third telematics unit, and activation of the fourth cellular telephone in the fourth telematics unit.

11. The method according to claim 10, the method further comprising connecting to the first cellular phone in the first telematics unit, the second cellular telephone in the second telematics unit, the third cellular phone in the third telematics unit, and the fourth cellular phone in the fourth telematics unit.

12. The method according to claim 5, wherein the account status is selected from the group consisting of active and inactive.

13. The method according to claim 5, wherein the account type is selected from the group consisting of personal, business, fleet, rental, and company vehicle.

14. A nontransitory computer-readable medium comprising computer-executable instructions for:

receiving an erroneous registry entry having a first mobile identification number that is not unique in that two or more cellular telephones associated with respective ones of two or more telematics units share the first mobile identification number such that a first one of the telematics units cannot send and receive calls;

sending a request to a wireless provider to select a first cellular telephone in the first telematics unit of the two or more telematics units, the first cellular telephone being associated with a first triplicate entry stored in a home location registry for the first cellular telephone, the first triplicate entry including a first mobile directory number, an erroneous mobile identification number, and a first electronic serial number;

sending a request to the wireless service provider to assign a second mobile identification number to the first cellular telephone;

updating the first cellular phone in the first telematics unit with the second mobile identification number;

notifying the wireless service provider of the updated status of the first cellular phone; and

requesting the wireless service provider to store the second mobile identification number in the first triplicate entry in the home location registry for the first cellular telephone.

15. The nontransitory computer-readable medium of claim 14 further comprising computer-executable instructions for:
