Method and apparatus for cellular network backup connectivity

1. A system comprising:

a processor configured to:

detect a presence of a wireless network access point usable for vehicular communication;

connect to the wireless access point; and

report connection information relating to the connected access point to an entity capable of establishing direct cellular connection with a vehicle, identifying the connected access point as an alternative communication method when cellular communication is unavailable and responsive to a determination that a cellular signal provided to a telematics control unit has fallen below predetermined usable threshold, searching, using a vehicle computer, for a usable dedicated short range communication (DSRC) access point in communicable proximity to a vehicle and reporting connection information for the DSRC access point to a remote entity along with instructions to utilize the DSRC access point for vehicle communication.

2. The system of claim 1 , wherein the access point is a Wi-Fi access point.

3. The system of claim 1 , wherein the access point is a dedicated short range communication access point.

4. The system of claim 1 , wherein the processor is configured to search for the access point responsive to a determination that a cellular signal has fallen below a predefined usability threshold.

5. The system of claim 1 , wherein the processor is configured to report the connection information responsive to a determination that a cellular signal has fallen below a predefined usability threshold.

6. The system of claim 1 , wherein the processor is configured to utilize the access point for communication with the entity, responsive to a determination that a cellular signal has fallen below a predefined usability threshold, until the processor determines that the cellular signal has risen above the predefined usability threshold.

7. The system of claim 1 , wherein the processor is configured to determine if the access point will remain in communicable proximity to the vehicle for more than a predetermined threshold period of time.

8. The system of claim 7 , wherein the processor is configured to report the connection information in response to a determination that the access point will remain in communicable proximity to the vehicle for more than the predetermined threshold period of time.

9. The system of claim 7 , wherein the processor is configured to determine if the access point will remain in communicable proximity to the vehicle for more than the predetermined threshold period of time based on vehicle speed.

10. The system of claim 7 , wherein the processor is configured to determine if the access point will remain in communicable proximity to the vehicle for more than the predetermined threshold period of time based on a vehicle route.

11. The system of claim 7 , wherein the processor is configured to determine if the access point will remain in communicable proximity to the vehicle for more than the predetermined threshold period of time based on a vehicle park-state.

12. The system of claim 1 , wherein the processor is configured to:

determine that a vehicle has been parked;

set a timer for periodically waking the vehicle if the vehicle is powered-down;

periodically wake the vehicle in accordance with the timer; and

responsive to waking the vehicle, compare a cellular signal to a predetermined usability threshold, wherein the processor is configured to:

report a usable cellular connection when the cellular signal is above the predetermined usability threshold and instruct the entity to use the wireless access point when the cellular signal is below the predetermined usability threshold.
