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 using a service of a service type based on at least a location of the mobile device;

obtaining course network statistics for the service type on network coverage areas surrounding the course;

predicting that the course will traverse an area in which a rate of loss of the service type exceeds a predetermined threshold; and

before the mobile device arrives at a portion of the course in the area, providing an indication of a predicted loss of the service, based on the course traversing the area and changing an operating setting of the mobile device.

2. The method of claim 1, further comprising determining that the mobile device is using the service.

3. The method of claim 1, wherein the service type comprises a voice service type, a data service type, a paging service type, or a network connectivity type.

4. The method of claim 1, further comprising:

determining an alternate course traversing a second area in which a second rate of loss of the service type is less than the rate of loss; and

causing a user of the mobile device to receive an indication of the alternate course.

5. The method of claim 4, wherein the indication of the alternate course comprises at least one of turn-by-turn directions, a cardinal direction, or an ordinal direction.

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

maintaining a location history of the mobile device;

obtaining a current location of the mobile device; and

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

7. The method of claim 1, wherein the indication comprises a time estimate of an occurrence of the predicted loss.

13. The method of claim 1, further comprising:

determining an alternate course traversing a second area having a second probability of loss that is less than the probability of loss; and

wherein the alert comprises an indication of the alternate course.

8. A method comprising:

predicting a course of a mobile device based on at least a location of the mobile device;

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

predicting that the course will traverse an area in which a probability of loss exceeds a predetermined threshold based on the course network statistics; and

before the mobile device arrives at a portion of the course in the area, in response to the predicting that the course will traverse the area, performing at least one of;

changing an operating setting of the mobile device.

9. The method of claim 8, wherein the probability of loss comprises a probability of connectivity loss.

10. The method of claim 9, wherein the probability of loss comprises a probability of loss of a service.

11. The method of claim 10, wherein the service comprises at least one of a voice service, a data service, or a paging service.

12. The method of claim 8, wherein the probability of loss is based on a loss rate.

14. A mobile device comprising:

a processor; and

memory coupled to the processor, the memory comprising executable instructions that cause the processor to effectuate operations comprising;

predicting a course of the mobile device based on at least a location of the mobile device;

determining a likelihood that the mobile device will lose a service based on a rate of loss along a future portion of the course;

providing, to a user of the mobile device, before the mobile device arrives at the future portion, a warning that the mobile device is likely to lose the service if the mobile device does adopt an alternative course and changing an operating setting of the mobile device.

15. The mobile device of claim 14, wherein the warning identifies the alternate course.

16. The mobile device of claim 14, further comprising a display in communication with the processor, wherein providing the warning comprises causing the display to display the warning.

17. The mobile device of claim 14, the operations further comprising determining a destination location, wherein predicting the course is further based on the destination location.

18. The mobile device of claim 14, wherein the service is one of a voice service, a data service, or a paging service.

19. The mobile device of claim 14, wherein changing the operating setting causes a reduction in power consumption of the mobile device responsive to the likelihood.
