Abstract

A method for selecting an air interface on a multi-mode wireless device capable of communicating over a plurality of air interfaces. The method comprising starting a first application and selecting a first application specific access list of a set of application specific access lists, the first application specific access list corresponding to the first application. The method also comprising selecting a first active network from the first application access specific list, the first network representing an available and most desirable network for the first application in the first application specific access list. The method further activating the first active network for use by the first application and switching from the first active network to a second active network if a user switches from the first application to a second application, wherein the first active network and the second active network are ascertained based on the set of application specific access lists.

Claims

1. A method for selecting an air interface on a multi-mode wireless device capable of communicating over a plurality of air interfaces, the method comprising:

accessing a plurality of technology specific access lists for a plurality of wireless technologies, each technology specific access list defining networks for a respective wireless technology;

ranking the networks in descending desirability according at least to application specific criteria of individual applications of a set of applications expected to be executed in the multi-mode wireless device and operational features of the plurality of wireless technologies; and

generating the set of application specific access lists based on the ranking, each application specific access list corresponding to a respective application of the set of applications expected to be executed in the multi-mode wireless device and including at least one of the networks associated with the plurality of technology specific access lists;

starting a first application;

selecting a first application specific access list of the set of application specific access lists, the first application specific access list corresponding to the first application;

selecting a first active network from the first application access specific list, the first active network representing an available and most desirable network for the first application in the first application specific access list;

activating the first active network for use by the first application; and

switching from the first active network to a second active network if a user switches from the first application to a second application, the second active network representing an available and most desirable network for the second application in a second application specific access list of said set of application specific access lists, wherein the first active network and the second active network are ascertained based on the set of application specific access lists, wherein the switching from the first active network to the second active network is performed even if the first active network is still available when switching to the second application.

2. The method of claim 1 further comprising:

determining a geographic region of the multi-mode wireless device; and

selecting networks according to the determined graphic region.

3. The method of claim 1 wherein the set of application specific access lists include at least one of a voice list, a data list, a high-speed data list, a low speed data list, a security list, a mobility list, and a voice-over-IP list.

4. The method of claim 1 further comprising storing the set of application specific access lists on the multi-mode wireless device.

5. The method of claim 4 wherein the storing the set of application specific access lists further comprises downloading the set of application specific access lists using an over an air interface.

6. The method of claim 1 further comprising storing the plurality of technology specific access lists on a remote server.

7. The method of claim 1 wherein the ranking the networks comprises:

assigning each of the networks a priority based on its suitability for a particular application; and

storing the priority in a data structure.

8. The method of claim 1 wherein the plurality of technology specific access lists include at least one of cdma2000 Ix, IxEV-DO, GPRS, GSM, GPRS, PHS, WiMax, and WLAN.

9. The method of claim 2 further comprising selecting the networks based on suitability for a particular application.

10. The method of claim 2 wherein the determining the geographic region comprises utilizing GPS.

11. The method of claim 2, further comprising acquiring a network.

12. A method for selecting an air interface on a multi-mode wireless device capable of communicating over a plurality of air interfaces, the method comprising:

accessing a plurality of technology specific access lists for a plurality of wireless technologies, each technology specific access list defining networks for a respective wireless technology;

ranking the networks in descending desirability according at least to application specific criteria pertaining to a combination of at least two different applications expected to be executed in the multi-mode wireless device and operational features of the plurality of wireless technologies; and

generating a set of application specific access lists based on the ranking, a first application specific access list corresponding to a respective combination of at least two different applications expected to be executed in the multi-mode wireless device and including at least one of the networks associated with the plurality of technology specific access lists;

selecting a first active network from the first application access specific list, the first active network representing an available and most desirable network for a first combination of at least two different applications in the first application specific access list;

activating the first active network for use by the first combination of at least two different applications; and

switching from the first active network to a second active network if a user switches from the first combination of at least two different applications to a second combination of at least two different applications, the second active network representing an available and most desirable network for the second combination of at least two different applications, wherein the first active network and the second active network are ascertained based on the set of application specific access lists, wherein the switching from the first active network to the second active network is performed even if the first active network is still available when switching to the second combination of at least two different applications.

13. The method of claim 12 further comprising storing the set of application specific access lists on the multi-mode wireless device.

14. The method of claim 13 wherein the storing the set of application specific access lists further comprises downloading the set of application specific access lists using an over an air interface.

15. The method of claim 12 further comprising storing the set of application specific access lists on a remote server.

16. The method of claim 12 further comprising storing the plurality of technology specific access lists on a remote server.

17. The method of claim 12 wherein the set of application specific access lists include at least one of a voice list, a data list, a high-speed data list, a low speed data list, a security list, a mobility list, and a voice-over-IP list.

18. The method of claim 12 further comprising:

determining a geographic region of the multi-mode wireless device; and

selecting the networks according to the determined geographic region.

19. The method of claim 18 wherein the determining the geographic region comprises utilizing GPS.
