The described method and system provide for synchronizing a mobile application on a mobile device with a DRx (discontinuous receive) schedule of a vehicle. When the vehicle ignition is turned off, a telecommunications unit on the vehicle sends a synchronization message to the mobile device, which allows the mobile application to synchronize with the DRx schedule of the vehicle. The DRx schedule includes a standby mode, a cyclic mode, and a powered down mode for the vehicle, and user requests inputted into the mobile application will be processed according to the mobile application's determination of vehicle availability during those modes. The mobile application is thus able to inform the user of the vehicle status at any point during the vehicle's DRx schedule without requiring any further information from the vehicle after the synchronization message. |

1. A method for synchronizing a mobile application on a mobile device with a discontinuous receive (DRx) schedule of a telematics-equipped vehicle, the method comprising:
determining, by a telematics unit of the telematics-equipped vehicle, that a vehicle ignition has been turned off; determining, by the telematics unit, whether cellular communications services are available for communications with the mobile device; adjusting, by the telematics unit, based on cellular communications services being unavailable, the DRx schedule of the telematics-equipped vehicle based on an amount of power consumed by the telematics unit when searching for the cellular communications services; sending, by the telematics unit, in response to determining that the vehicle ignition has been turned off and in response to determining that cellular communications services are available, a synchronization message to the mobile device for coordinating communications between the mobile device and the telematics unit, the synchronization message including information regarding the DRx schedule of the telematics-equipped vehicle, wherein the information regarding the DRx schedule of the telematics-equipped vehicle indicates multiple time periods at which the telematics unit is available during a cyclic mode of a fixed duration of the telematics unit; while the telematics unit is available in the cyclic mode, receiving, by the telematics unit, after the sending, a request from the mobile device, wherein the time at which the request was sent by the mobile device is based on the information regarding the DRx schedule of the telematics-equipped vehicle; and carrying out, by the telematics unit, the received request; wherein the mobile device is a user's mobile computing device, and the method further comprises: determining, by the mobile device, whether the telematics unit is available for carrying out requests and whether the telematics unit is in the cyclic mode based on the information regarding the DRx schedule of the telematics-equipped vehicle; and notifying, in response to determining that the telematics unit is not available for carrying out requests and the telematics unit is in the cyclic mode, the user of a next time the telematics unit will become available via a mobile application of the mobile device. |
