Systems and methods for timer continuation in a power reset scenario

1. A method for timer continuation in a power reset scenario by an in-vehicle system, comprising:

beginning a power reset;

determining whether a timer associated with an emergency call was running before the power reset, wherein the emergency call is an eCall or a test-or-reconfiguration eCall, and wherein the timer is a T3242 timer or a T3243 timer;

continuing timer use if the timer was running before the power reset; and

registering the in-vehicle system on a network if the timer was running before the power reset.

2. The method of claim 1 , further comprising initiating a location area update procedure if the timer was running before the power reset.

3. The method of claim 1 , further comprising entering an idle state if the timer was running before the power reset.

4. The method of claim 1 , wherein continuing timer use comprises resuming the timer based on a previously stored timer value.

5. The method of claim 1 , wherein continuing timer use comprises restarting the timer.

6. An in-vehicle system, comprising:

timer control circuitry that determines whether a timer associated with an emergency call was running before a power reset, wherein the emergency call is an eCall or a test-or-reconfiguration eCall, and wherein the timer is a T3242 timer or a T3243 timer;

wherein the timer control circuitry continues timer use if the timer was running before the power reset; and

communication control circuitry coupled to the timer control circuitry, wherein the communication control circuitry registers the in-vehicle system on a network if the timer was running before the power reset.

7. The in-vehicle system of claim 6 , wherein the communication control circuitry initiates a location area update procedure if the timer was running before the power reset.

8. The in-vehicle system of claim 6 , wherein the communication control circuitry causes the in-vehicle system to enter an idle state if the timer was running before the power reset.

9. The in-vehicle system of claim 6 , wherein continuing timer use comprises resuming the timer based on a previously stored timer value.

10. The in-vehicle system of claim 6 , wherein continuing timer use comprises restarting the timer.

11. A non-transitory tangible computer-readable medium having instructions thereon, the instructions comprising:

code for causing an in-vehicle system to begin a power reset;

code for causing the in-vehicle system to determine whether a timer associated with an emergency call was running before the power reset, wherein the emergency call is an eCall or a test-or-reconfiguration eCall, and wherein the timer is a T3242 timer or a T3243 timer;

code for causing the in-vehicle system to continue timer use if the timer was running before the power reset; and

code for causing the in-vehicle system to register the in-vehicle system on a network if the timer was running before the power reset.

12. The non-transitory tangible computer-readable medium of claim 11 , the instructions further comprising code for causing the in-vehicle system to initiate a location area update procedure if the timer was running before the power reset.

13. The non-transitory tangible computer-readable medium of claim 11 , the instructions further comprising code for causing the in-vehicle system to enter an idle state if the timer was running before the power reset.

14. The non-transitory tangible computer-readable medium of claim 11 , wherein continuing timer use comprises resuming the timer based on a previously stored timer value.

15. The non-transitory tangible computer-readable medium of claim 11 , wherein continuing timer use comprises restarting the timer.

16. An apparatus for timer continuation in a power reset scenario, comprising:

means for beginning a power reset;

means for determining whether a timer associated with an emergency call was running before the power reset, wherein the emergency call is an eCall or a test-or-reconfiguration eCall, and wherein the timer is a T3242 timer or a T3243 timer;

means for continuing timer use if the timer was running before the power reset; and

means for registering the apparatus on a network if the timer was running before the power reset.

17. The apparatus of claim 16 , further comprising means for initiating a location area update procedure if the timer was running before the power reset.

18. The apparatus of claim 16 , further comprising means for entering an idle state if the timer was running before the power reset.

19. The apparatus of claim 16 , wherein continuing timer use comprises resuming the timer based on a previously stored timer value.

20. The apparatus of claim 16 , wherein continuing timer use comprises restarting the timer.
