Abstract

A method of selecting a network from a plurality of available access networks is provided. The method includes identifying, by using a wireless user equipment, the plurality of access networks and identifying, by using a wireless user equipment, an invoked application. The method includes selecting, by using a wireless user equipment, a first access network from the plurality of access networks based, at least in part, on the application. A connection is established to the first access network in response to an application requirement. A handover procedure is invoked from the first access network to a second access network of the plurality of access networks in response to application requirements.

Claims

1. A method of operating a mobile device comprising:

connecting to a WIFI network and a cellular network;

displaying an indication of availability of the WIFI network and the cellular network;

accessing data through the WIFI network in response to an application request from an application executing on the mobile device;

detecting a first condition indicative of a quality of the WIFI network;

detecting, in response to a subsequent application request and before or at a time of receiving a response to the subsequent application request, a second condition indicative of a time responsiveness of the WIFI network;

evaluating user settings, wherein the user settings include a roaming rule, a connectivity rule, and an application profile of the application;

in response to detecting the first condition and the second condition and evaluating the user settings, determining a time responsiveness of the cellular network; and

based on the detected first condition and detected second condition, the evaluated user settings, the time responsiveness of the cellular network, and the application executing on the mobile device, sending the subsequent application request through the cellular network in response to the application request executing on the mobile device, wherein requests from another application executing on the mobile device continue to access data through the WIFI network.

2. The method of claim 1, wherein sending requests to the cellular network is performed on an application-by-application basis such that the requests are evaluated for sending to the cellular network for each application making requests.

3. The method of claim 1 wherein detecting the first condition further comprises:

evaluating a network preference.

4. The method of claim 1 wherein the quality of the WIFI network is based on signal strength.

5. The method of claim 1 wherein the quality of the WIFI network is based on network throughput.

6. The method of claim 1, wherein each of the WIFI network and the cellular network are operating in a respective TCP session.

7. The method of claim 1, wherein detecting the first condition or the second condition is performed in response to a socket open request.

8. The method of claim 1, further including registering the mobile device with the cellular network.

9. The method of claim 8, wherein sending requests to the cellular network is further based on registration of the mobile device with the cellular network.

10. The method of claim 1, wherein sending requests to the cellular network occurs while the mobile device remains connected to the WIFI network.

11. The method of claim 1, wherein sending requests to the cellular network is further based on an application programming interface (API).

12. The method of claim 1, further including sending requests of the mobile device to the WIFI network at a subsequent time based on the time responsiveness of the WIFI network and the cellular network at that subsequent time and the application executing on the mobile device.

13. The method of claim 1, wherein requests from another application executing on the mobile device are not sent to the cellular network.

14. A mobile device comprising:

a memory and a processor;

a network interface operable to;

connecting to a WIFI network and a cellular network;

displaying an indication of availability of the WIFI network and the cellular network;

accessing data through the WIFI network in response to an application request from an application executing on a mobile device;

detecting a first condition indicative of a quality of the WIFI network;

detecting, in response to a subsequent application request and before or at a time of receiving a response to the subsequent application request, a second condition indicative of a time responsiveness of the WIFI network;

evaluating user settings, wherein the user settings include a roaming rule, a connectivity rule, and an application profile of the application;

in response to detecting the first condition and the second condition and evaluating the user settings, determining a time responsiveness of the cellular network; and

based on the detected first condition and detected second condition, the evaluated user settings, the time responsiveness of the cellular network, and the application executing on the mobile device, sending the subsequent application request through the cellular network in response to the application request executing on the mobile device,

wherein requests from another application executing on the mobile device continue to access data through the WIFI network.

15. The mobile device of claim 14, wherein the network interface is further operable to send requests to the cellular network on an application-by-application basis such that the requests are evaluated for sending to the cellular network for each application making requests.

16. The mobile device of claim 14, wherein the first condition is detected by evaluating a network preference.

17. The mobile device of claim 14, wherein the quality of the WIFI network is based on signal strength.

18. The mobile device of claim 14, wherein the quality of the WIFI network is based on network throughput.

19. The mobile device of claim 14, wherein each of the WIFI network and the cellular network are operating in a respective TCP session.

20. The mobile device of claim 14, wherein the network interface is further operable to detect the first condition or the second condition in response to a socket open request.

21. The mobile device of claim 14, wherein the network interface is further operable to register the mobile device with the cellular network.

22. The mobile device of claim 21, wherein the network interface is further operable to send requests to the cellular network based on registration of the mobile device with the cellular network.

23. The mobile device of claim 14, wherein the network interface is further operable to send requests to the cellular network while the mobile device remains connected to the WIFI network.

24. The mobile device of claim 14, wherein the network interface is further operable to send requests to the cellular network based on an application programming interface (API).

25. The mobile device of claim 14, wherein the network interface is further operable to send requests to the cellular network based on a user preferences.

26. The mobile device of claim 14, wherein the network interface is further operable to send requests from the mobile device to the WIFI network at a subsequent time based on the time responsiveness of the WIFI network and the cellular network at that subsequent time and the application executing on the mobile device.

27. The mobile device of claim 14, wherein requests from the another application executing on the mobile device are not sent to the cellular network.

28. The mobile device of claim 14, wherein a functionality to send a request through the cellular network is enabled or disabled by a user of the mobile device.
