Abstract

A mobile station is used by one of a plurality of subscribers of a home area wireless service provider. The mobile station includes a memory that stores a list of preferred wireless carrier identities for use by the mobile station when roaming. The list of preferred wireless carrier identities is stored based upon a national account assigned to the mobile station for a plurality of market areas. The mobile station also includes a selector that automatically selects a preferred wireless carrier from the list stored in the memory when the mobile station is roaming and enters one of the market areas of the plurality of market areas.

Claims

1. A mobile station used by one of a plurality of subscribers of a home area wireless service provider, comprising:

a memory that stores a list of preferred wireless carrier identities for use by the mobile station when roaming, said list of preferred wireless carrier identities being stored based upon a national account assigned to the mobile station for a plurality of market areas; and

a selector that automatically selects a preferred wireless carrier from the list stored in said memory when the mobile station is roaming and enters one of the plurality of market areas.

2. The mobile station of claim 1, wherein the mobile station switches to a preferred wireless carrier, selected from the list of preferred wireless carrier identities, to use for communication in response to the mobile station roaming to one of the plurality of market areas.

3. The mobile station of claim 1, wherein the list of preferred wireless carrier identities is downloaded to the memory of the mobile station from a message center.

4. The mobile station of claim 3, wherein the list of preferred wireless carrier identities is downloaded to the memory via a communications link established between the message center and the memory of the mobile station.

5. The mobile station of claim 4, wherein the communications link comprises a wireless communications link.

6. The mobile station of claim 4, wherein the communications link comprises a wired communications link.

7. The mobile station according to claim 1, wherein the list comprises a preferred wireless carrier and an alternative wireless carrier for at least one of the plurality of market areas.

11. The mobile station as set forth in claim 1, wherein said national account comprises a first agreement between the home area wireless service provider and a customer.

12. The mobile station as set forth in claim 11, wherein, as a result of said agreement, said customer receives at least one of a different rate and a different selected service than are provided to a mass market.

13. The mobile station as set forth in claim 12, wherein said home area wireless service provider provides said different rates and different selected services, and wherein said different rates and selected services are provided to said customer through at least one second agreement between said home area wireless service provider and at least one third party wireless service provider.

15. The mobile station as set forth in claim 1, wherein the mobile station receives at least one of a different rate and a different selected service than are provided to a mass market subscriber, the mass market subscriber being assigned by default to a mass market national account.

8. A method for selecting a preferred wireless carrier for a mobile station to enable wireless communication when the mobile station is roaming outside of a home market area of the mobile station, a database of preferred wireless carriers for a plurality of market areas based upon predetermined national accounts being provided at a predetermined location remote from the mobile station, a list of preferred wireless carriers being generated based upon a national account assigned to the mobile station, the list being stored in a storage device associated with the mobile station designated with the national account to enable a selection of a preferred wireless carrier band, the method comprising:

receiving, at the mobile station, a signal transmitted by a wireless carrier;

determining whether the received signal is transmitted by a wireless carrier in a home market area of the mobile station; and

switching, based on the list in the storage device of the mobile station, a communications band of the mobile station to a preferred wireless carrier band related to the roaming market area when it is determined that the received signal is not transmitted by a wireless carrier in the home market area of the mobile station.

9. A method for downloading a list of preferred wireless communication bands stored in a database to a memory device of each of a plurality of mobile stations, the database containing the list of preferred wireless communication bands from which each mobile station may select a preferred wireless communication band when the mobile station is roaming outside of a home market area of the mobile station, the database having a plurality of national account fields, and a plurality of home market area fields, each mobile station being assigned to a national account and a home market area, the method comprising:

determining when the list of preferred wireless communication bands stored in the memory of each mobile stations is outdated;

determining, when the list is outdated, if each mobile station is registered with a home location register;

locating each mobile station and downloading an updated list to each mobile station when it is determined the mobile station is registered with the home location register; and

notifying a message center when the mobile station is not registered with the home location register and, thereafter, downloading a new preferred wireless communication band list to each mobile station when it is determined that the mobile station later registers with the home location register.

10. The method of claim 9, wherein the downloading further comprises a throttling scheme which controls the number of mobile stations to which the downloading occurs during a predetermined period of time.

14. A mobile station used by one of a plurality of subscribers of a home area wireless service provider, comprising:

a memory that stores a list of preferred wireless carrier identities for use by the mobile station when roaming, said list of preferred wireless carrier identities being stored based upon a national account assigned to the mobile station for a plurality of market areas, each of the plurality of subscribers of the home area wireless service provider being assigned to a national account, the national account comprising one of a default mass market national account and at least one other national account; and

a selector that automatically selects a preferred wireless carrier from the list stored in said memory when the mobile station is roaming and enters one of the market areas of the plurality of market areas.
