Abstract

Mobile device user notifications of highly likely call drops or service losses are provided. A wireless network can determine from the location history of a mobile device if that mobile device is likely to lose connectivity to the wireless network or to a particular wireless service and issue an alert to the user. The form of the alert can be through one of various types of mobile device messages, or through an application on the mobile device. The mobile device'"'"'s location can be determined using the global positioning system. Alternative directions can be provided to the user so that the user can travel without losing connectivity. The user may provide a destination before beginning travel, and receive a suggested course of travel that keeps the user within a higher quality coverage area.

Claims

1. A method comprising:

predicting a course of a mobile device;

collecting course network statistics on network coverage areas surrounding the course;

predicting that the course will traverse an area with an unacceptable rate of dropped calls by determining that a rate of dropped calls in the network coverage areas surrounding the course exceeds a predetermined threshold; and

in response to predicting that the course will traverse an area with the unacceptable rate of dropped calls, providing, to the mobile device, an indication of a predicted loss of network connectivity.

2. The method of claim 1, wherein predicting the course comprises:

accessing a history of global positioning system (GPS) coordinates of the mobile device;

obtaining current GPS coordinates of the mobile device; and

predicting the course of the mobile device in accordance with the accessed and obtained GPS coordinates.

3. The method of claim 1, wherein predicting the course comprises:

maintaining a history of the mobile device'"'"'s location, determined based on network measurements, over a period of time;

obtaining a current location of the mobile device, determined based on network measurements, and

predicting the course based on the history and the current location.

4. The method of claim 1, further comprising:

determining at least one alternate course, the at least one alternate course predicted to traverse an area not having the unacceptable rate of dropped calls; and

providing the at least one alternate course to the mobile device.

5. The method of claim 4, wherein the at least one alternate course is provided to the mobile device as turn-by-turn driving directions.

6. The method of claim 4, wherein the at least one alternate course is provided to the mobile device in the form of at least one of a cardinal and an ordinal direction.

7. The method of claim 1, further comprising providing to the mobile device a time estimate of an occurrence of the predicted loss of network connectivity.

8. The method of claim 1, wherein the course network statistics comprise a ratio of dropped calls to total calls.

9. A system comprising:

at least one memory; and

at least one processor in communication with the at least one memory, wherein the at least one processor is configured to;

predict a course of a mobile device;

collect course network statistics on network coverage areas surrounding the course;

predict that the course will traverse an area with an unacceptable rate of dropped calls by determining that a rate of dropped calls in the network coverage areas surrounding the course exceeds a predetermined threshold;

in response to predicting that the course will traverse the area with the unacceptable rate of dropped calls, provide, to the mobile device, an indication of a predicted loss of network connectivity.

10. The system of claim 9, wherein the at least one processor is further configured to provide a time estimate of the predicted loss of network connectivity.

11. The system of claim 9, wherein the course network statistics comprise a ratio of dropped calls to total calls.

12. The system of claim 9, wherein the at least one processor is further configured to provide a current probability of a dropped call to the mobile device.

13. The system of claim 9, wherein the at least one processor is further configured to:

determine at least one alternate course, the at least one alternate course predicted to traverse an area without the unacceptable rate of dropped calls; and

provide the at least one alternate course to the mobile device.

14. The system of claim 13, wherein the at least one processor configured to determine the at least one alternate course further comprises the at least one processor configured to:

collect potential course network statistics on network coverage areas surrounding a plurality of potential courses; and

determine if the potential course network statistics indicate the unacceptable rate of dropped calls for each of the plurality of potential courses; and

select the at least one potential course from among the plurality of potential courses that does not correspond to potential course network statistics that indicate the unacceptable rate of dropped calls.

15. The system of claim 13, wherein the at least one processor configured to provide the at least one alternate course to the mobile device comprises the at least one processor configured to display on the mobile device an option to request the at least one alternate course.

16. A non-transitory computer-readable medium, the non-transitory computer-readable medium having stored thereon computer-executable instructions for:

predicting a course of a mobile device;

collecting network statistics on network coverage areas surrounding the course;

predicting that the course will traverse an area with an unacceptable rate of dropped calls by determining that a rate of dropped calls in the network coverage areas surrounding the course exceeds a predetermined threshold; and

in response to predicting that the course will traverse an area with the unacceptable rate of dropped calls, providing to the mobile an indication of a predicted loss of network connectivity.

17. The non-transitory computer-readable medium of claim 16, wherein the non-transitory computer-readable medium is configured on a navigation system.
