Blocking application traffic for resource conservation in a mobile device

1. A mobile device comprising:

a memory;

a processor configured to control the mobile device for:

communicating over a shared channel and an application specific channel, wherein the application specific channel is a channel for an application on the mobile device to communicate with an application server;

blocking the application specific channel to offload traffic therefrom to the shared channel, wherein the blocking occurs in response to a screen of the mobile device being off and the blocking includes blocking the application from accessing the application server over the application specific channel;

wherein blocking the application from accessing the application server includes suspending the application;

receiving a message directed to the application over the shared channel from a messaging server;

allowing the application to access the application server over the application specific channel in response to receipt of the message;

wherein allowing the application to access the application server includes resuming the application for a period of time; and

re-blocking the application specific channel after allowing the application to access the application server over the application specific channel for the period of time.

2. The mobile device of claim 1 , wherein suspending the application includes killing the application.

3. The mobile device of claim 1 , wherein blocking the application specific channel includes blocking keepalive traffic.

4. The mobile device of claim 3 , wherein the blocked keepalive traffic is offloaded to the shared channel.

5. The mobile device of claim 1 , wherein the application specific channel is a TCP connection.

6. The mobile device of claim 1 , further comprising unblocking the application specific channel when user activity is detected, wherein the user activity includes whether the mobile device is being interacted with.

7. The mobile device of claim 6 , wherein the application specific channel that is unblocked is a subsequent TCP connection.

8. The mobile device of claim 1 , wherein the screen of the mobile device is off as a result of the mobile device not being interacted with by a user.

9. A non-transient computer readable storage medium containing computer readable program code configured for:

communicating over a shared channel and an application specific channel, wherein the application specific channel is a channel for an application on a mobile device to communicate with an application server;

blocking the application specific channel to offload traffic therefrom to the shared channel, wherein the blocking occurs in response to a screen of the mobile device being off and the blocking includes blocking the application from accessing the application server over the application specific channel;

wherein blocking the application from accessing the application server includes suspending the application;

receiving a message directed to the application over the shared channel from a messaging server;

allowing the application to access the application server over the application specific channel in response to receipt of the message;

wherein allowing the application to access the application server includes resuming the application for a period of time; and

re-blocking the application specific channel after allowing the application to access the application server over the application specific channel for the period of time.

10. The computer readable storage medium of claim 9 , wherein suspending the application includes killing the application.

11. The computer readable storage medium of claim 9 , wherein blocking the application specific channel includes blocking keepalive traffic.

12. The computer readable storage medium of claim 11 , wherein the blocked keepalive traffic is offloaded to the shared channel.

13. The computer readable storage medium of claim 9 , wherein the application specific channel is a TCP connection.

14. The computer readable storage medium of claim 9 , further comprising unblocking the application specific channel when user activity is detected, wherein the user activity includes whether the mobile device is being interacted with.

15. The computer readable storage medium of claim 14 , wherein the application specific channel that is unblocked is a subsequent TCP connection.

16. The computer readable storage medium of claim 9 , wherein the screen of the mobile device is off as a result of the mobile device not being interacted with by a user.

17. A method comprising:

communicating over a shared channel and an application specific channel, wherein the application specific channel is a channel for an application on a mobile device to communicate with an application server;

blocking the application specific channel to offload traffic therefrom to the shared channel, wherein the blocking occurs in response to a screen of the mobile device being off and the blocking includes blocking the application from accessing the application server over the application specific channel;

wherein blocking the application from accessing the application server includes suspending the application;

receiving a message directed to the application over the shared channel from a messaging server;

allowing the application to access the application server over the application specific channel in response to receipt of the message;

wherein allowing the application to access the application server includes resuming the application for a period of time; and

re-blocking the application specific channel after allowing the application to access the application server over the application specific channel for the period of time.
