Abstract

The present invention provides a method for managing mobile handset portability within a telematics equipped mobile vehicle. The method includes assigning a primary telematics unit identifier to a user account, assigning the primary telematics unit identifier to a mobile handset, associating the mobile handset with any one of a plurality of telematics units operating within the mobile vehicle communication system, and operating the associated telematics unit. The step of associating the mobile handset may include coupling the mobile handset to the telematics unit, communicating the assigned telematics unit identifier of the mobile handset to a service provider, and downloading user preferences from the service provider wherein the user preferences are based on the user account associated with the communicated telematics unit identifier. The step of downloading the user preferences may include determining the user preferences at the service provider and receiving the user preferences from the service provider.

Claims

1. A method for operating a telematics unit within a mobile vehicle communication system, the method comprising:

assigning a primary telematics unit identifier to a user account;

assigning the primary telematics unit identifier to a mobile handset;

associating the mobile handset with any one of a plurality of telematics units operating within the mobile vehicle communication system; and

operating the associated telematics unit;

wherein the step of associating the mobile handset with any one of a plurality of telematics units operating within the mobile vehicle communication system comprises;

coupling the mobile handset to the telematics unit;

determining if the telematics unit coupled to the mobile handset is a primary telematics unit, the primary telematics unit including the primary telematics unit identifier;

determining if the telematics unit coupled to the mobile handset is a secondary telematics unit, the secondary telematics unit not including the primary telematics unit identifier; and

routing calls to the determined telematics unit.

2. The method of claim 1, wherein the step of routing calls to the determined telematics unit comprises:

sending the call to the secondary telematics unit when the mobile handset is coupled to the secondary telematics unit;

determining if the call is answered at the secondary telematics unit; and

forwarding the call to the primary telematics unit when the call is not answered.

3. The method of claim 2, further comprising:

determining if the call is answered at the primary telematics unit; and

forwarding the call to voice mail when the call is not answered.

4. A computer readable medium for operating a telematics unit within a mobile vehicle, comprising:

computer readable code for assigning a primary telematics unit identifier to a user account;

computer readable code for assigning the primary telematics unit identifier to a mobile handset;

computer readable code for associating the mobile handset with any one of a plurality of telematics units operating within the mobile vehicle communication system; and

computer readable code for operating the associated telematics unit

wherein the computer readable code for associating the mobile handset with any one of a plurality of telematics units operating within the mobile vehicle communication system comprises;

computer readable code for determining that the mobile handset is coupled to the telematics unit;

computer readable code for determining if the telematics unit coupled to the mobile handset is a primary telematics unit, the primary telematics unit including the primary telematics unit identifier;

computer readable code for determining if the telematics unit coupled to the mobile handset is a secondary telematics unit, the secondary telematics unit not including the primary telematics unit identifier; and

computer readable code for routing calls to the determined telematics unit.

5. The computer readable medium of claim 4, wherein the computer readable code for routing calls to the determined telematics unit comprises:

computer readable code for sending the call to the secondary telematics unit when the mobile handset is coupled to the secondary telematics unit;

computer readable code for determining if the call is answered at the secondary telematics unit; and

computer readable code for forwarding the call to the primary telematics unit when the call is not answered.

6. The computer readable medium of claim 5, further comprising:

computer readable code for determining if the call is answered at the primary telematics unit; and

computer readable code for forwarding the call to voice mail when the call is not answered.

7. A method for operating a telematics unit on a vehicle and within a mobile vehicle communication system, the method comprising:

associating a primary telematics unit identifier with a user account;

associating the primary telematics unit identifier with a mobile handset;

associating the mobile handset with a selected telematics unit operating within the mobile vehicle communication system;

determining if the selected telematics unit is a primary telematics unit or a secondary telematics unit, wherein the primary telematics unit includes the primary telematics unit identifier and the secondary telematics unit does not include the primary telematics unit identifier; and

operating the selected telematics unit.

8. The method of claim 7, wherein the step of operating the selected telematics unit comprises routing calls to the selected telematics unit.

9. The method of claim 8, wherein routing calls to the selected telematics unit further comprises establishing voice communication if the call is answered.

10. The method of claim 8, wherein routing calls to the selected telematics unit comprises:

sending a call to the mobile handset;

determining if the call is answered at the mobile handset; and

forwarding the call to the selected telematics unit if the call is not answered at the mobile handset.

11. The method of claim 10, wherein routing calls to the selected telematics unit further comprises:

determining if the call is answered at the selected telematics unit; and

forwarding the call to an answering system if the call is not answered at the selected telematics unit.

12. The method of claim 8, wherein routing calls to the selected telematics unit comprises:

sending a call to the secondary telematics unit when the mobile handset is associated with the secondary telematics unit;

determining if the call is answered at the secondary telematics unit; and

forwarding the call to the primary telematics unit if the call is not answered at the secondary telematics unit.

13. The method of claim 7, further comprising the step of communicating the telematics unit identifier to a service provider.

14. The method of claim 7, further comprising the step of downloading user preferences from a service provider using the selected telematics unit.

15. The method of claim 14, wherein the user preferences are based on the user account associated with the primary telematics unit identifier.

16. The method of claim 14, wherein the user preferences are based on a mobile vehicle type.

17. The method of claim 7, wherein the primary telematics unit identifier is a mobile identification number.

18. A method for operating a telematics unit on a vehicle and within a mobile vehicle communication system, the method comprising:

associating a telematics unit identifier with a user account;

associating the telematics unit identifier with a mobile handset;

associating the mobile handset with a selected telematics unit operating within the mobile vehicle communication system;

routing calls to the mobile handset;

determining if the call is answered at the mobile handset; and

forwarding the call to the selected telematics unit if the call is not answered at the mobile handset.

19. The method of claim 18, wherein the step of routing calls to the selected telematics unit further comprises establishing voice communication if the call is answered.

20. The method of claim 18, wherein the step of routing calls to the selected telematics unit further comprises:

determining if the call is answered at the selected telematics unit; and

forwarding the call to an answering system if the call is not answered at the selected telematics unit.

21. The method of claim 18, further comprising the step of downloading user preferences from a service provider to the selected telematics unit.
