Abstract

Apparatus, device, methods and system relating to a vehicular telemetry environment for identifying in real time unpredictable network communication faults in network zones based upon pre-processed raw telematics big data logs that may include GPS data and an indication of vehicle status data, and supplemental data that may further include location data and network data.

Claims (41)

1. A system comprising:

a mobile device associated with a vehicle; and

a remote device,

said mobile device configured to:

determine a device expected communication rate for the mobile device, and

communicate the device expected communication rate for the mobile device to the remote device; and

said remote device is configured to:

determine an expected communication rate for a network zone based on at least the device expected communication rate for the mobile device, and

determine whether the network zone is experiencing a communication fault based on the expected communication rate for the network zone and an actual communication rate for the network zone.

2. The system of claim 1 , wherein determining the device expected communication rate for the mobile device comprises detecting a vehicle status of the vehicle.

3. The system of claim 2 , wherein the vehicle status is an ignition status indication for the vehicle.

4. The system of claim 1 , wherein the mobile device is further configured to:

in response to determining that the mobile device is in an active state, set the device expected communication rate for the mobile device to a first rate, and

in response to determining that the mobile device is in an inactive state, set the device expected communication rate for the mobile device to one of at least one lower rate lower than the first rate.

5. The system of claim 4 , wherein the first rate is at least one communication with the remote device in each of at least one period of 100 seconds.

6. The system of claim 5 , wherein said inactive state includes a sleep state associated with a second rate of the at least one lower rate, and the second rate is at least one communication with the remote device in each of at least one period of 1800 seconds.

7. The system of claim 6 , wherein said inactive state includes a deep sleep state associated with a third rate of the at least one lower rate, the third rate is lower than the second rate, and the third rate is at least one communication with the remote device in each of at least one period of 86,400 seconds.

8. The system of claim 4 , wherein the mobile device is further configured to:

in response to determining that the mobile device is in the inactive state, determine whether the mobile device is in a first power saving mode or a second power saving mode.

9. The system of claim 8 , wherein:

setting the device expected communication rate to the one of the at least one lower rate comprises:

setting the device expected communication rate to a second rate, of the at least one lower rate, in response to a determination that the mobile device is the first power saving mode; and

setting the device expected communication rate to a third rate, of the at least one lower rate, that is lower than the second rate, in response to determining that the mobile device is in the second power saving mode.

10. The system of claim 8 , wherein determining whether the mobile device is in the first power saving mode or the second power saving mode comprises:

determining that the mobile device is in the first power saving mode in response to determining that the mobile device is in the inactive state; and

determining that the mobile device is in the second power saving mode in response to determining that more than a threshold period of time has elapsed since the mobile device was determined to be in the inactive state.

11. The system of claim 1 , further comprising:

one or more of the mobile device of claim 1 , disposed in the network zone,

wherein the remote device is configured to determine the expected communication rate for the network zone based on the device expected communication rate determined for each mobile device of the one or more mobile devices disposed in the network zone.

12. The system of claim 11 , wherein determining whether the network zone is experiencing the communication fault further comprises:

comparing for at least one time frame the actual communication rate for the network zone, reflecting communications from each mobile device disposed in the network zone, to said expected communication rate; and

indicating the communication fault in the network zone when said actual communication rate is not equal to said expected communication rate within said at least one time frame.

13. The system of claim 12 , wherein:

the expected communication rate relates to a total number of network connections expected to be established by the one or more mobile devices disposed within the network zone within a period of time;

the device expected communication rate relates to a total number of network connections expected to be established by the mobile device disposed within the network zone within the period of time; and

the actual communication rate relates to a total number of network connections established by the one or more mobile devices within the period of time.

14. The system of claim 1 , wherein:

the mobile device includes a positional device, said positional device configured to provide position information of the mobile device, and

the remote device is configured to determine a location of the communication fault in the network zone based at least in part on the position information of the mobile device.

15. The system of claim 14 , wherein:

the remote device is configured to provide a fault indication in response to determining that the network zone is experiencing the communication fault, the fault indication identifying the location of the communication fault in the network zone.
