1. A method for processing calls at a telematics unit on a telematics-equipped vehicle, the method comprising:
- determining, at the telematics unit, that an ongoing call is active when vehicle ignition is switched to an off state;
determining that the ongoing call is not a call that is excepted from a call timer;
activating the call timer in response to determining that the ongoing call is not excepted;
operating the call timer to measure an elapsed time during the ongoing call and while the vehicle ignition is in the off state; and
determining, based upon the elapsed time measured by the call timer, that the call timer has reached an expiration and, in response to the expiration, the telematics unit terminating the ongoing call and transitioning into a discontinuous receive (DRx) mode.

Abstract
The described method and system provide for processing telematics service-related calls on a telematics-equipped vehicle when the vehicle ignition is off. By utilizing one or more call timers, the described invention is able to prevent excessive drain to the vehicle battery while still providing broad access to telematics services when the vehicle ignition is off. Certain types of calls may be excepted from the call timers, and different types of calls may use different call timers. A call center may also intervene and modify the process by changing the values of the timers.

7. A non-transitory computer-readable medium having processor-executable instructions stored thereon for processing calls at a telematics unit on a telematics-equipped vehicle, the processor-executable instructions, when executed by a processor, causing the following to be performed:
-
determining that an ongoing call is active when vehicle ignition is switched to an off state; determining that the ongoing call is not a call that is excepted from a call timer; activating the call timer in response to determining that the ongoing call is not excepted; operating the call timer to measure an elapsed time during the ongoing call and while the vehicle ignition is in the off state; and determining, based upon the elapsed time measured by the call timer, that the call timer has reached an expiration and, in response to the expiration, the telematics unit terminating the ongoing call and transitioning into a discontinuous receive (DRx) mode. - View Dependent Claims (8, 9, 10, 11, 12)

13. A method for processing calls at a telematics unit on a telematics-equipped vehicle, the method comprising:
-
facilitating, at the telematics unit, a first call while vehicle ignition is in an off state; determining that the first call is of a first call type; operating a first call timer associated with the first call type to measure a first elapsed time while the first call is ongoing; facilitating, at the telematics unit, a second call while the vehicle ignition is in the off state; determining that the second call is of a second call type, wherein the second call type has a calling protocol that consumes more power than a calling protocol of the first call type; operating a second call timer associated with the second call type to measure a second elapsed time while the second call is ongoing; and determining, based upon the elapsed time measured by the second call timer, that the second call timer has reached an expiration and, in response to the expiration, the telematics unit terminating the second call and transitioning into a discontinuous receive (DRx) mode. - View Dependent Claims (14, 15, 16, 17, 18)
