Abstract

A method and apparatus that enable a mobile electronic device to automatically and seamlessly maintain optimal network connectivity by selectively connecting to the most appropriate, currently available data or communications network. Guidelines for what constitutes optimal network connectivity are provided by pre-selected user preferences or objectives. These are combined into one or more rules that can be interpreted by a software module operating on the mobile electronics device, and used to switch between the available networks in a way that makes intelligent use of the mobile device resources, and provides seamless support for any applications running on the device while roaming through regions of changing network availability, or as the service quality of available networks varies.

providing a first and a second network connection capability operational on said mobile electronic device;

providing a rule comprising at least one pre-selected user preference and at least one quality of connection parameter; and

selecting one of said first and second network connection capabilities responsive to said rule.

10. The method of claim 9 wherein said first and second network connection capability comprise a wireless communications link.

11. The method of claim 10, wherein said pre-selected user preference is one or more of a network identifier, an application'"'"'s connection-driving parameter, a detection mode, an accesses mode, a network priority, and a mode of operation.

12. The method of claim 11, wherein said mode of operation is selected from an always-on mode and a connect-on-demand mode.

13. The method of claim 12, wherein said connect-on-demand mode comprises only connecting to one of said networks when an application requiring network access is detected.

14. The method of claim 9, wherein said quality of connection parameter is one or more of a ping off-set, a ping interval and a ping timeout.

16. A computer-readable medium, operable in conjunction with a mobile electronic device having a first and a second network connection capability, said computer-readable medium comprising instructions for:

parsing a rule comprising at least one pre-selected user preference and at least one quality of connection parameter for said networks; and

selecting one of said first and second network connection capabilities responsive to said rule.

17. A computing device comprising:

a computer-readable medium operable in conjunction with a mobile electronic device having a first and a second network connection capability, said computer-readable medium comprising instructions for;

parsing a rule comprising at least one pre-selected user preference and at least one quality of connection parameter for said networks; and
