Abstract

Techniques for performing system selection based on requirements and preferences of applications are described. A terminal maintains a policy table containing applications supported by the terminal, priorities of the applications, radio technologies that can be used for each application, and priorities of the radio technologies for each application. The terminal manages policies associated with the supported applications and radio technologies, determines the most suitable radio technology for each application, and activates and deactivates radio technologies in response to events, e.g., the terminal being turned on, a call being placed, the terminal leaving the coverage of a radio technology, etc.

7. The apparatus of claim 1, wherein the at least one processor is configured to receive a request for communication from an application of lower priority than the at least one application, to activate a radio technology for the lower priority application if supportable concurrently with the at least one radio technology, and to reject the request if the radio technology for the lower priority application is not supportable concurrently with the at least one radio technology.

8. The apparatus of claim 1, wherein the at least one processor is configured to receive a request for communication from an application of higher priority than the at least one application, to activate a radio technology for the higher priority application, and to deactivate each of the at least one radio technology not supportable concurrently with the radio technology for the higher priority application.

9. The apparatus of claim 8, wherein the at least one processor is configured to move an application with a deactivated radio technology over to the radio technology for the higher priority application.

10. The apparatus of claim 1, wherein the at least one processor is configured to select a group of radio technologies from among a plurality of groups of radio technologies, the selected group comprising the at least one radio technology.

11. The apparatus of claim 10, wherein the at least one processor is configured to select a group comprising a most preferred radio technology for each of the at least one application.

12. The apparatus of claim 10, wherein the plurality of groups are associated with different priorities, and wherein the at least one processor is configured to select a highest priority group comprising the at least one radio technology.

13. The apparatus of claim 1, wherein the at least one processor is configured to activate a radio technology for an application in a minimum application set when the application is launched.

14. The apparatus of claim 13, wherein the at least one processor is configured to deactivate each of the at least one radio technology not supportable concurrently with the radio technology for the application in the minimum application set.

15. The apparatus of claim 1, wherein the memory is configured to store a table of applications and a set of radio technologies usable by each application.

16. The apparatus of claim 15, wherein the memory is further configured to store priorities of the applications in the table.

17. The apparatus of claim 15, wherein the memory is further configured to store preferences of the radio technologies usable by each application.

18. A method for wireless communication, comprising:
