Abstract

Architecture that facilitates power conservation in mobile devices such as cell phones using prediction. The architecture is an algorithmic-based solution that transforms infrequently-captured geolocation data of an entity into a continuous probable location approximation. Given the location history and additional data about the recent location of the mobile device, the current location of the device can be estimated with some probability. Additionally, given the location history and additional data about the recent location of the device, the probability of the device actually being at a given point on a map is computed.

First claim

What is claimed is:

1 . A mobile device comprising:
a processor; and computer storage memory having computer-executable instructions stored thereon which, when executed by the processor, configure the mobile device to: wherein the mobile device is associated with a first user; access, at the mobile device, location updates of a second user, the location updates of the second user periodically stored on a network for access by the mobile device; and predict a realtime geographical location of the second user based on processing of a location update and facilitate power conservation in the mobile device by waiving access to the network for new location updates of the second user.

2 . The mobile device of claim Error! Reference source not found., wherein the location updates include at least one of geographical coordinates of the location of the second user, or metadata comprised of speed information and navigation vector of the second user.

3 . The mobile device of claim Error! Reference source not found., wherein the geographical point of the second user is predicted based on a destination of the second user.

4 . The mobile device of claim Error! Reference source not found., wherein the geographical point of the second user is predicted based on some or all of historical location updates of the second user.

5 . The mobile device of claim Error! Reference source not found., wherein the geographical point of the second user is predicted based on location updates of other users.

6 . The mobile device of claim Error! Reference source not found., wherein the geographical point of the second user based on location updates and information from a navigation application of the second user.

7 . The mobile device of claim Error! Reference source not found., further configured to a data obtain traffic data and road topology vector data for processing to predict the geographical point.

8 . The mobile device of claim Error! Reference source not found., wherein a location update of the second user to the network is not performed when the second user travels along a same vector and at an approximately constant speed.

9 . One or more computer-storage media having computer executable instructions embodied thereon, which when executed, cause a computing device to perform a method, comprising acts of:
monitoring power consumption of a mobile device of a user during user navigation along geographical routes using a map application; sending location updates from the mobile device to a network as metadata that includes speed information and location vector information, based on location update criteria, the location updates for access by other users; accessing, via the mobile device, metadata of a second user stored on the network as location updates of the second user, the metadata stored on the network as the second user navigates using a map application; estimating a realtime geographical location of the second user based on the accessed metadata, the estimating performed at the mobile device to conserve power in the mobile device rather than expending power accessing the network for additional location updates of the second user; and utilizing a microprocessor that executes instructions stored in a memory.

10 . The media of claim 15 , further comprising sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is approaching an intersection.

11 . The media of claim 9 , further comprising refraining from sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is maintaining speed along a vector.

12 . The media of claim 9 , further comprising refraining from sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is maintaining travel along a same road of a map.

13 . The media of claim 9 , further comprising estimating the realtime geographical location of the second user based in part on consideration of live traffic data.

14 . The media of claim 9 , further comprising overriding the sending of a location update based solely on the update criteria in view of a type of power source of the mobile device.

15 . A method, comprising acts of:
monitoring power consumption of a mobile device of a user during user navigation along geographical routes using a map application; sending location updates from the mobile device to a network as metadata that includes speed information and location vector information, based on location update criteria, the location updates for access by other users; accessing, via the mobile device, metadata of a second user stored on the network as location updates of the second user, the metadata stored on the network as the second user navigates using a map application; estimating a realtime geographical location of the second user based on the accessed metadata, the estimating performed at the mobile device to conserve power in the mobile device rather than expending power accessing the network for additional location updates of the second user; and utilizing a microprocessor that executes instructions stored in a memory.

16 . The method of claim 15 , further comprising sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is approaching an intersection.

17 . The method of claim 15 , further comprising refraining from sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is maintaining speed along a vector.

18 . The method of claim 15 , further comprising refraining from sending a location update from the mobile device to the network for access by the other users when the location update criteria indicates the user is maintaining travel along a same road of a map.

19 . The method of claim 15 , further comprising estimating the realtime geographical location of the second user based in part on consideration of live traffic data.

20 . The method of claim 15 , further comprising overriding the sending of a location update based solely on the update criteria in view of a type of power source of the mobile device.
