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 method, comprising acts of:
monitoring power consumption of a mobile device of a first user during user navigation along geographical routes using a map application;
accessing, via the mobile device of the first user, metadata of a second user stored on a network as location updates, the metadata comprising speed data and vector data, and stored on the network as the second user navigates along geographical routes using a map application;
estimating according to a probable location approximation via the mobile device of the first user, 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 based on location update importance, the power conserved by periodically accessing the network for additional location updates of the second user rather than expending power by continuously accessing the network for the additional location updates of the second user; and
configuring a microprocessor to execute instructions stored in a memory, the instructions related to the acts of monitoring, accessing, and estimating.

2. The method of claim 1 , further comprising performing the monitoring, accessing, and estimating as operations transparent to the user.

3. The method of claim 1 , further comprising estimating the geographical location based on samples of geolocation data of other users or based on previous geolocation data of the second user.

4. The method of claim 1 , further comprising estimating the geographical location of the second user based on location and map information of the second user, or based on a destination of the second user.
