Abstract

A method, apparatus, and computer program product for reducing battery consumption while tracking a location of a mobile device. A location tracking application at the mobile device registers to receive location updates from the mobile device. The application receives a location update from the mobile device and determines whether to transmit location information from the received location update to a remote web server.

Claims

1. A method of reducing battery consumption while tracking a location of a mobile device, comprising:

registering at a location tracking application to receive location updates from the mobile device;

receiving a location update from the mobile device; and

determining at the mobile device whether to transmit location information from the received location update to a remote web server, including;

determining whether an accuracy level of the received location update is at least an acceptable accuracy level, wherein if the accuracy of the received location update is at least the acceptable accuracy level, updated location information is sent to the remote web server,

determining whether the received location update indicates that the mobile device has travelled at least a minimum distance when the accuracy of the received location update is below the acceptable accuracy level, wherein when the received location update indicates that the mobile device has travelled at least a minimum distance updated location information is sent to the remote web server.

2. The method of claim 1, wherein determining whether to transmit location information to the remote web server comprises:

determining a level of location monitoring to be applied.

3. The method of claim 1, wherein determining whether to transmit location information to the remote web server comprises:

determining whether the received location update indicates that the mobile device has traveled more than a maximum speed since a previous location update,

wherein when the received location update indicates that the mobile device has travelled more than a maximum speed since a previous location update, updated location information is not sent to the remote web server.

4. The method of claim 1, wherein when the received location update indicates that the mobile device has not travelled at least the minimum distance a determination is made as to whether a number of received location updates that have not been forwarded to the remote web server is at least a predetermined number N,

when the number of received location updates that have not been forwarded to the remote web server is at least N, updated location information is sent to the remote web server, and

when the number of received location updates that have not been forwarded to the remote web server is less than N, updated location information is not sent to the remote web server.

5. The method of claim 1, wherein when the accuracy of the received location update is below the acceptable accuracy level, determining whether to transmit location information to the remote web server further comprises:

determining a source of the location in the received location update, wherein if the source of the location is a Global Positioning System (GPS) module of the mobile device, updated location information is sent to the remote web server.

6. The method of claim 5, wherein when the source of the location is not the GPS module of the mobile device, determining whether to transmit location information to the remote web server further comprises:

determining whether the received location update indicates that the mobile device has travelled at least a second minimum distance since a previous location update,

wherein when the received location update does not indicate that the mobile device has travelled at least the second minimum distance since the previous location update, updated location information is not sent to the remote web server.

7. The method of claim 6, wherein when the received location update indicates that the mobile device has travelled at least the second minimum distance since the previous location update, determining whether to transmit location information to the remote web server further comprises:

determining whether the accuracy of the received location update is greater than that of the location information last reported to the remote web server,

wherein if the accuracy of the received location update is greater than that of the location information last reported to the remote web server, updated location information is sent to the remote web server.

8. The method of claim 7, wherein if the accuracy of the received location update is not greater than that of the location information last reported to the remote web server, determining whether to transmit location information to the remote web server further comprises:

determining whether an amount of time since the location information was last reported to the web server is at least a predetermined amount of time,

wherein if the amount of time since the location information was last reported to the web server is at least the predetermined amount of time, updated location information is sent to the remote web server; and

wherein if the amount of time since the location information was last reported to the web server is not at least the predetermined amount of time, updated location information is not sent to the remote web server.
