Abstract

A system that uses historical position information accumulated in an apparatus to determine whether locations and/or routes may be classified as significant. A classification of a location or route as significant may be utilized in configuring localization in the apparatus. Localization configuration may include, for example, setting a type technology utilized in determining apparatus position.

Claims

1. A method, comprising:

selecting, by an apparatus, a localization configuration from a plurality of localization configurations, the selected localization configuration for use by the apparatus to determine positioning whenever the apparatus is at a particular location that is also classified as a significant place or route for the apparatus,

wherein a localization configuration that provides positioning information at the particular location that is less accurate than positioning information provided by other localization configurations at the particular location is selected if it is determined that the less accurate positioning information provided by the selected localization configuration distinguishes the particular location from any another location that is also classified as a significant place or route for the apparatus; and

wherein a localization configuration that provides positioning information at the particular location that is more accurate than positioning information provided by other localization configurations at the particular location is selected if it is determined that the less accurate positioning information provided by the other localization configurations does not distinguish the particular location from any other location that is also classified as a significant place or route for the apparatus;

receiving position information in the apparatus;

determining whether the current location of the apparatus was previously classified as a significant place or route based on the position information;

if the current location of the apparatus was previously classified, applying a localization configuration in the apparatus based on the previous classification; and

wherein the other localization configurations comprise at least one of a satellite-based system, a cellular network-based system and a short-range wireless network.

2. The method of claim 1, wherein at least one of the determining and applying steps are performed by another apparatus in communication with the apparatus.

3. The method of claim 1, wherein evaluating location information comprises considering at least one of user factors including number of visits to a location, duration of visits to the location, total number of different stops made within the boundaries of the location and distance between each of the stops, and location factors including what localization technologies are available in the location, reliability for each of the localization technologies and route types in the location.

4. The method of claim 1, wherein if the current location of the apparatus can be considered a significant place or route, generating new classification criteria for the significant place or route.

5. The method of claim 4, further comprising reconciling or merging the existing classification criteria with the new classification criteria.

6. The method of claim 1, wherein the classification criteria is based on at least one of position resolution criteria and energy consumption criteria.

7. The method of claim 1, wherein applying the localization configuration comprises setting at least one of Global Positioning System (GPS), local-area networking or cellular membership for use in localization in the apparatus.

22. The method of claim 1, wherein the selecting of a localization configuration for use by the apparatus is based on a distance between the particular location and another location that is also classified as a significant place or route for the apparatus.

code configured to cause an apparatus to select a localization configuration from a plurality of localization configurations, the selected localization configuration for use by the apparatus to determine positioning whenever the apparatus is at a particular location that is also classified as a significant place or route for the apparatus,

wherein a localization configuration that provides positioning information at the particular location that is less accurate than positioning information provided by other localization configurations at the particular location is selected if it is determined that the less accurate positioning information provided by the selected localization configuration distinguishes the particular location from any another location that is also classified as a significant place or route for the apparatus; and

wherein a localization configuration that provides positioning information at the particular location that is more accurate than positioning information provided by other localization configurations at the particular location is selected if it is determined that the less accurate positioning information provided by the other localization configurations does not distinguish the particular location from any other location that is also classified as a significant place or route for the apparatus;

code configured to cause an apparatus to receive position information;

code configured to cause an apparatus to determine whether the current location of the apparatus was previously classified as a significant place or route based on the position information;

code configured to cause an apparatus to, if the current location of the apparatus was previously classified, apply a localization configuration in the apparatus based on the previous classification; and

code configured to cause an apparatus to, if the current location of the apparatus was not previously classified, determine if the current location of the apparatus is considered a significant place or route by evaluating location information accumulated in the apparatus over time to determine whether the apparatus has frequently visited the current location,
