Abstract

A communications network administers intelligent roaming capabilities and features in a mobile station. The network includes a central database to store intelligent roaming information corresponding to respective service providers; and a service database to store and forward information corresponding to the intelligent roaming information to be programmed into the mobile station, which information is updated periodically by the central database. The mobile station is connected to a mobile coverage area based on the forwarded information.

Claims

1. A communications network for administering intelligent roaming capabilities and features in a mobile station, comprising:

a central database to store intelligent roaming information corresponding to respective service providers; and

a service database to store and forward information corresponding to the intelligent roaming information to be programmed into the mobile station, which information is updated periodically by the central database,

wherein the mobile station is connected to a mobile coverage area based on the forwarded information.

2. The communications network of claim 1, wherein the central database stores a list of mobile stations supporting the intelligent roaming capabilities.

3. The communications network of claim 1, wherein the service database receives updated information corresponding to a list of mobile stations requiring updates from the central database, formats the updated information to be compatible with the mobile stations and sends the updated information to the mobile stations.

4. The communications network of claim 3, wherein each of the mobile stations in the list are identified by one of a mobile identification number, international mobile station identity or home location register.

5. The communications network of claim 2, wherein

a code is broadcast to indicate when the central database list has been updated, and

when a respective mobile station determines an update is required based on the broadcasted code, a request message for reprogramming is sent to the central database.

6. The communications network of claim 1, wherein

the central database includes a computer with a memory and a database application to store the intelligent roaming information, and

the service database includes a computer with an application to store and forward the information to be programmed into the mobile station.

7. A method of administering intelligent roaming capabilities and features in a mobile station of a communications network, comprising:

storing intelligent roaming information corresponding to respective service providers in a central database;

forwarding information corresponding to the intelligent roaming information to be programmed into the mobile station from a service database, which information is updated periodically by the central database; and

connecting the mobile station to a mobile coverage area based on the forwarded information.

8. The method of claim 7, wherein the central database stores a list of mobile stations supporting the intelligent roaming capabilities.

9. The method of claim 7, wherein the service database receives updated information corresponding to a list of mobile stations requiring updates from the central database, formats the updated information to be compatible with the mobile stations and sends the updated information to the mobile stations.

10. The method of claim 9, wherein each of the mobile stations in the list are identified by one of a mobile identification number, international mobile station identity or home location register.

11. The method of claim 8, further comprising:

broadcasting a code to indicate when the central database list has been updated; and

sending a request message for reprogramming to the central database when a respective mobile station determines an update is required based on the broadcasted code.

12. The method of claim 7, wherein

the central database includes a computer with a memory and a database application to store the intelligent roaming information, and

the service database includes a computer with an application to store and forward the information to be programmed into the mobile station.

13. A non-transitory computer readable medium that stores a program for administering intelligent roaming capabilities and features in a mobile station of a communications network, the program when executed by a processor comprising:

stores intelligent roaming information corresponding to respective service providers in a central database;

forwards information corresponding to the intelligent roaming information to be programmed into the mobile station from a service database, which information is updated periodically by the central database; and

connects the mobile station to a mobile coverage area based on the forwarded information.

14. The non-transitory computer readable medium of claim 13, wherein the central database stores a list of mobile stations supporting the intelligent roaming capabilities.

15. The non-transitory computer readable medium of claim 13, wherein the service database receives updated information corresponding to a list of mobile stations requiring updates from the central database, formats the updated information to be compatible with the mobile stations and sends the updated information to the mobile stations.

16. The non-transitory computer readable medium claim 15, wherein each of the mobile stations in the list are identified by one of a mobile identification number, international mobile station identity or home location register.

17. The non-transitory computer readable medium claim 14, the program when executed by a processor further comprising:

broadcasts a code to indicate when the central database list has been updated; and

sends a request message for reprogramming to the central database when a respective mobile station determines an update is required based on the broadcasted code.

18. The non-transitory computer readable medium claim 13, wherein

the central database includes a computer with a memory and a database application to store the intelligent roaming information, and

the service database includes a computer with an application to store and forward the information to be programmed into the mobile station.
