Abstract

Techniques for filtering broadcast SMS messages at a mobile station based on network configuration, user configuration, and/or user preferences. In one method, a broadcast message is initially received, and one or more filtering criteria are applied to the received broadcast message. The filtering criteria are defined by settings stored in a removable module (e.g., the R-UIM) coupled to the receiver. The received broadcast message is then processed if it is not filtered out by the one or more filtering criteria. The one or more filtering criteria may include (1) those imposed by a service provider and defined in a network configuration setting, (2) those determined by the mobile user and defined in a user configuration setting, (3) those selected by the mobile user based on user preferences, which allow for filtering of broadcast messages based on service category, language, and priority, or (4) any combination of the above.

Claims

1. A method of filtering broadcast messages at a receiver in a wireless communication network, comprising:

receiving a broadcast message;

applying one or more filtering criteria to the received broadcast message, wherein the filtering criteria are defined by settings stored in a removable module coupled to the receiver; and

processing the received broadcast message if it is not filtered out by the one or more filtering criteria.

2. The method of claim 1, wherein the one or more filtering criteria include those imposed by a service provider.

3. The method of claim 2, wherein the filtering criteria imposed by the service provider are defined by a network configuration setting that indicates all broadcast messages are allowed to be received, no broadcast messages are allowed to be received, or only broadcast messages for entries programmed in a service table are allowed to be received.

4. The method of claim 3, wherein the network configuration setting is stored in a first elementary file in the removable module.

5. The method of claim 1, wherein the one or more filtering criteria include user-determined filtering criteria.

6. The method of claim 5, wherein the user-determined filtering criteria are defined by a user configuration setting that indicates all broadcast messages are to be received, no broadcast messages are to be received, or only broadcast messages for entries programmed in a service table are to be received.

7. The method of claim 6, wherein the user configuration setting is stored in a second elementary file in the removable module.

8. The method of claim 1, wherein the one or more filtering criteria include user-selected criteria for user preferences.

9. The method of claim 8, wherein the user-selected filtering criteria allow for filtering of broadcast messages based on service category, language, priority, or any combination thereof.

10. The method of claim 8, wherein the user-selected filtering criteria apply to entries programmed in a service table.

11. The method of claim 10, wherein each entry in the service table corresponds to a unique combination of service category and language.

12. The method of claim 10, wherein each entry in the service table can be selected or unselected, and wherein only broadcast messages for selected entries may be processed if the service table is enabled for use.

13. The method of claim 10, wherein the service table and user-selected filtering criteria are stored in a third elementary file in the removable module.

14. The method of claim 1, further comprising:

detecting for a duplicate of the received broadcast message, and wherein the received broadcast message is only processed if a duplicate is not detected.

15. The method of claim 1, wherein the wireless communication network is a cdma2000 network that implements ANSI-41.

16. A method of filtering broadcast messages at a mobile station in a CDMA communication network, comprising:

receiving a broadcast message;

applying filtering criteria imposed by a service provider to the received broadcast message;

applying user-determined filtering criteria to the received broadcast message;

applying user-selected filtering criteria to the received broadcast message, wherein the filtering criteria are stored in a removable module coupled to the mobile station; and

processing the received broadcast message if it is not filtered out by the filtering criteria.

17. The method of claim 16, wherein the service provider imposed filtering criteria are defined by a network configuration setting, the user-determined filtering criteria are defined by a user configuration setting, and the user-selected filtering criteria are defined for entries programmed in a service table.

18. The method of claim 17, wherein the network configuration setting, user configuration setting, and service table are stored in one or more elementary files in the removable module.

19. A method of programming a network configuration setting used to filter broadcast messages at a receiver in a wireless communication network, comprising:

exchanging over the air a message carrying the network configuration setting to be programmed into the receiver, wherein the network configuration setting determines the capability of the mobile station for receiving broadcast messages.

20. The method of claim 19, wherein the network configuration setting for the mobile station indicates that all broadcast messages are allowed to be received, no broadcast messages are allowed to be received, or only broadcast messages for entries programmed in a service table are allowed to be received.

21. A memory communicatively coupled to a digital signal processing device (DSPD) capable of interpreting digital information to:

receive a broadcast message;

apply one or more filtering criteria to the received broadcast message, wherein the filtering criteria are defined by settings stored in a removable module coupled to the receiver; and

process the received broadcast message if it is not filtered out by the one or more filtering criteria.

22. An apparatus in a wireless communication network and operable to filter incoming broadcast messages, comprising:

means for receiving a broadcast message;

means for applying one or more filtering criteria to the received broadcast message;

a removable module for storing settings indicative of the filtering criteria; and

means for processing the received broadcast message if it is not filtered out by the one or more filtering criteria.

23. The apparatus of claim 22, wherein the one or more filtering criteria include filtering criteria imposed by the service provider and defined by a network configuration setting.

24. The apparatus of claim 22, wherein the one or more filtering criteria include user-determined filtering criteria defined by a user configuration setting.

25. The apparatus of claim 22, wherein the one or more filtering criteria include user-selected filtering criteria that allow for filtering of broadcast messages based on service category, language, priority, or any combination thereof.

26. The apparatus of claim 22, wherein the removable module stores the settings in one or more elementary files.
