System and method for mobile device application pre-emption

1. A mobile device, comprising:

a wireless transceiver to provide a wireless communication link to a communication network;

an initially active application;

a pre-empting application to provide communication based on the wireless communication link; and

an interface to present an indication of a communication directed to the pre-empting application being received via the wireless communication link for less than 2 seconds before the pre-empting application pre-empts the initially active application, wherein the pre-empting application automatically pre-empts the initially active application without user action when no rejection user input is received before expiration of a predetermined time period after the indication, and wherein when the rejection user input is received after the communication and before the predetermined time period expires, the mobile device transmits a message to the communication network rejecting the communication.

2. The mobile device of claim 1 , wherein the communication network is one of a code division multiple access (CDMA) network, a global system for mobile communications (GSM) network, a long-term evolution (LTE) network, and a worldwide interoperability for microwave access (WiMAX) network.

3. The mobile device of claim 1 , wherein the initially active application is one of an email application, a short message service (SMS) application, a multimedia message service (MMS) application, a game application, a media player application, and a browser application.

4. The mobile device of claim 1 , wherein the indication is at least one of a screen dim, a keyboard backlight dim, an audio tone, a light emitting diode (LED) illumination, and an icon display.

5. The mobile device of claim 4 , wherein the indication comprises a screen dim and a keyboard backlight dim.

6. The mobile device of claim 5 , wherein the screen dim and the keyboard backlight dim are presented for less than one second.

7. The mobile device of claim 5 , wherein the screen dim and the keyboard backlight dim are presented for less than 200 milliseconds.

8. The mobile device of claim 7 , wherein the pre-empting application pre-empts the initially active application no more than about 600 milliseconds after an initiation of the screen dim.

9. A mobile device interface application pre-emption indication method, the method comprising:

initially activating, by a mobile device, an application;

subsequently receiving, by a wireless transceiver of the mobile device, a communication directed to a pre-empting application, wherein the wireless transceiver provides a wireless communication link to a mobile communication network;

in response to the wireless transceiver receiving the communication, presenting, by an interface of the mobile device, an indication of the communication before redirecting inputs from the initially active application to the pre-empting application, wherein the indication is at least one of a transient display dim and a transient vibration;

automatically pre-empting the initially active application by the pre-empting application without user action when no rejection user input is received before expiration of a predetermined time period after the indication, wherein when the rejection user input is received by the interface after the communication and before expiration of the predetermined time period, the inputs to the interface are not redirected from the initially active application to the pre-empting application in response to receiving the communication; and

the wireless transceiver transmitting a message to the mobile communication network cancelling the wireless communication link when the rejection user input is received by the interface.

10. The method of claim 9 , wherein inputs are redirected from the initially active application to the pre-empting application a predetermined time after the communication is received, where the predetermined time is longer than an average time of human stimulus-response and less than four times the average time of human stimulus-response.

11. The method of claim 10 , where the predetermined time is more than 300 milliseconds and less than 1200 milliseconds.

12. The method of claim 9 , wherein the transient display dim and the transient vibration occur for less than about 200 milliseconds.

13. A method of providing notification of application pre-emption to a mobile device, the method comprising:

receiving, by a mobile device that comprises an initially active application, a communication from a mobile communication network directed to a pre-empting application on the mobile device;

subsequently presenting, by the mobile device, a transient indication of the communication;

automatically pre-empting the initially active application by the pre-empting application without user action when no rejection user input is received before expiration of a first predefined time duration after the transient indication; and

in response to the automatic pre-emption, blocking, by the mobile device, some but not all input to the mobile device for a second predefined time duration after the pre-empting application becomes active to promote avoidance of input into the pre-empting application that is intended for the initially active application.

14. The method of claim 13 , further comprising

receiving, by the mobile device, a rejection user input after the communication and before the first predefined time duration passes; and

in response to the rejection user input, transmitting, by the mobile device, a message to the mobile communication network rejecting the communication.

15. The method of claim 13 , wherein the second predefined time duration is less than 1 second.

16. The method of claim 15 , wherein the second predefined time duration is less than 200 milliseconds.

17. The method of claim 13 , wherein the transient indication comprises dimming a display of the mobile device and dimming a keyboard of the mobile device for less than about 200 milliseconds and wherein the first predefined time period is about 600 milliseconds.
