Abstract

To provide “transparent” broadcast services for a multi-mode wireless device capable of communicating with multiple wireless communication networks, a composite set of pertinent parameters for broadcast messages used by the multiple networks is defined. The parameters of the broadcast message for each network are mapped to corresponding parameters in the composite set. The composite set of parameters is used for processing and displaying broadcast messages received from the multiple networks. A broadcast message for each network (e.g., a CBS message in GSM or a broadcast SMS message in CDMA) is received and processed in accordance with the parameters of the message and filtering configurations applicable for the network. The parameters of the broadcast message are mapped to corresponding parameters in the composite set. The broadcast message is further processed and displayed based on the parameters in the composite set.

Claims

1. A wireless device comprising:

a first module operable to process a first broadcast message for a first wireless communication system in accordance with parameters of the first broadcast message;

a second module operable to process a second broadcast message for a second wireless communication system in accordance with parameters of the second broadcast message; and

a third module operable to map the parameters of the first and second broadcast messages to corresponding parameters in a set of parameters defined for broadcast services.

2. The wireless device of claim 1, wherein the first broadcast message is a Cell Broadcast Service (CBS) message for Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications System (UMTS) systems, and wherein the second broadcast message is a broadcast Short Message Service (SMS) message used for a Code Division Multiple Access (CDMA) system.

3. The wireless device of claim 1, further comprising:

a fourth module operable to process a third broadcast message for a third wireless communication system in accordance with parameters of the third broadcast message, and wherein the third module is further operable to map the parameters of the third broadcast message to corresponding parameters in the set of parameters defined for broadcast services.

4. The wireless device of claim 1, further comprising:

a fourth module operable to display the first and second broadcast messages based on the parameters in the set.

5. The wireless device of claim 4, wherein the fourth module is further operative to provide the parameters in the set for user review and selection instead of the parameters of the first and second broadcast messages.

6. The wireless device of claim 1, wherein each of the parameters in the set is associated with a mapped parameter for the first broadcast message, a mapped parameter for the second broadcast message, or a mapped parameter for both the first and second broadcast messages.

7. The wireless device of claim 6, wherein each parameter in the set associated with a mapped parameter for both the first and second broadcast messages can take on all values possible for the mapped parameter for the first and second broadcast messages.

8. The wireless device of claim 6, wherein each parameter in the set associated with a mapped parameter for the first broadcast message can take on all values possible for the mapped parameter of the first broadcast message and a default value for the second broadcast message.

9. The wireless device of claim 1, wherein the set includes a service identifier parameter indicative of broadcast services provided by the first and second systems.

10. The wireless device of claim 1, wherein the set includes an encoding parameter indicative of character sets used for broadcast messages received from the first and second networks and a language parameter indicative of languages used for the broadcast messages.

11. The wireless device of claim 1, wherein the set includes a display mode parameter indicative of display options for broadcast messages received from the first and second networks and a message replacement parameter used to replace old broadcast messages with new broadcast messages.

12. The wireless device of claim 1, wherein the first module is further operable to filter broadcast messages for the first system based on first filtering configurations, and wherein the second module is further operable to filter broadcast messages for the second system based on second filtering configurations.

13. The wireless device of claim 12, wherein the third module is operable to maintain the first and second filtering configurations for the first and second systems and to provide the first filtering configurations to the first module and the second filtering configurations to the second module.
