System and method for resolving contention among applications requiring data connections between a mobile communications device and a wireless network

1. A method for resolving contention among applications operable on a mobile communications device that require data connections to a wireless network, the method comprising:

conducting at least two data connections between the mobile communications device and the wireless network, each of the data connections associated with a connected application operating on the mobile communications device;

requesting a data connection for an unconnected application operable on the mobile communications device;

releasing one of the data connections responsive to the request, the releasing including selecting one of the connected applications by a contention manager based upon a comparison of first and second contention parameters associated with each of the connected applications and releasing the data connection associated with the selected connected application; and

establishing the data connection between the mobile communications device and the wireless network for the unconnected application.

2. The method as recited in claim 1 wherein the step of conducting at least two data connections between the mobile communications device and the wireless network further comprises conducting the maximum number of data connections allowed by the mobile communications device.

3. The method as recited in claim 1 wherein the step of conducting at least two data connections between the mobile communications device and the wireless network further comprises conducting the maximum number of data connections allowed between the mobile communications device and the wireless network.

4. The method as recited in claim 1 wherein each of the applications further comprises an application requiring constant connectivity.

5. The method as recited in claim 1 wherein the step of releasing one of the data connections responsive to the request further comprises comparing the first contention parameters prior to comparing the second contention parameters.

6. The method as recited in claim 1 wherein the step of releasing one of the data connections responsive to the request further comprises comparing data traffic associated with the data connections of the connected applications to determine the selected connected application.

7. The method as recited in claim 1 wherein the step of releasing one of the data connections responsive to the request further comprises comparing a duration of connection associated with the data connections of the connected applications to determine the selected connected application.

8. A mobile communications device comprising:

a wireless transceiver operable to conduct at least two data connections between the mobile communications device and a wireless network, each of the data connections associated with a connected application operating on the mobile communications device;

a processor coupled to the wireless transceiver and operable to process a request for a data connection for an unconnected application operable on the mobile communications device, to release one of the data connections associated with one of the connected applications and to establish a data connection between the mobile communications device and the wireless network for the unconnected application; and

a contention manager operable to select the connected application to be released based upon a comparison of first and second contention parameters associated with each of the connected applications.

9. The mobile communications device as recited in claim 8 wherein the data connections between the mobile communications device and the wireless network further comprise a maximum number of data connections allowed by the mobile communications device.

10. The mobile communications device as recited in claim 8 wherein the data connections between the mobile communications device and the wireless network further comprise a maximum number of data connections allowed between the mobile communications device and the wireless network.

11. The mobile communications device as recited in claim 8 wherein each of the applications further comprises an application requiring constant connectivity.

12. The mobile communications device as recited in claim 8 wherein the contention parameter associated with each of the connected applications further comprises an application priority associated with each of the connected applications.

13. The mobile communications device as recited in claim 8 wherein the second contention parameters are compared only if the conflict cannot be resolved by comparison of the first contention parameters.

14. The mobile communications device as recited in claim 8 wherein the contention parameter associated with each of the connected applications further comprises a duration of the data connection associated with each of the connected application.

15. A computer readable medium encoded with computer instructions, comprising:

computer instructions executable by a processor of a mobile communications device operable to conduct at least two data connections with a wireless network, each of the data connections associated with a connected application operating on the mobile communications device, the computer instructions for resolving contention among applications operable on the mobile communications device by:

receiving a request for a data connection for an unconnected application operable on the mobile communications device;

selecting one of the connected applications based upon a comparison of first and second contention parameters associated with each of the connected applications;

releasing the data connection associated with the selected connected application; and

establishing the data connection between the mobile communications device and the wireless network for the unconnected application.

16. The computer readable medium as recited in claim 15 wherein the data connections between the mobile communications device and the wireless network further comprise a maximum number of data connections allowed by the mobile communications device.

17. The computer readable medium as recited in claim 15 wherein the data connections between the mobile communications device and the wireless network further comprise a maximum number of data connections allowed between the mobile communications device and the wireless network.

18. The computer readable medium as recited in claim 15 wherein each of the applications further comprises an application requiring constant connectivity.

19. The computer readable medium as recited in claim 15 wherein selecting one of the connected applications further comprises comparing the application priority associated with the connected applications to determine the selected connected application.

20. The computer readable medium as recited in claim 15 wherein selecting one of the connected applications further comprises comparing data traffic associated with the data connections of the connected applications to determine the selected connected application.
