Method and apparatus for location notification using location context information
Provided is a method and apparatus for location notification using location context information. In accordance with an embodiment of the disclosure, a mobile device automatically generates location context information that indicates a point of interest in a vicinity of the mobile device. For example, if the user of the mobile device is at home, then the location context information indicates that the user is at home instead of merely indicating latitude/longitude information corresponding to the location of the home. The mobile device displays the location context information in order to convey the location of the mobile device in a manner that is meaningful without the need for a map. Alternatively, or additionally, the mobile device provides the location context information to at least one other device. This serves to inform other users of the location of the mobile device in a manner that is meaningful without the need for a map.

11. The method of claim 1 , wherein the communal database of public points of interest comprises a database of public landmarks including buildings and businesses.
12. The method of claim 1 , wherein the communal database of public points of interest is located at a server.
13. A mobile device comprising:
a wireless access radio;
a processor; and
a location context notifier configured for:
determining a current location of the mobile device;
based on the current location of the mobile device, determining a point of interest in a vicinity of the current location of the mobile device by automatically selecting one of a plurality of points of interest according to at least one criterion such that the selected point of interest conveys the current location of the mobile device;
generating location context information indicating the point of interest; and
executing a location notification using the location context information in order to indicate the current location of the mobile device, wherein the location context information is not displayed on a map;
wherein:
the plurality of points of interest comprise public points of interest; and
determining a point of interest in a vicinity of the current location of the mobile device comprises querying a communal database for a public point of interest in the vicinity of the current location of the mobile device.
14. The mobile device of claim 13 , wherein the location context notifier is configured for generating location context information indicating the point of interest by:
generating the location context information based on both the current location and movement of the mobile device.
15. The mobile device of claim 13 , wherein determining the point of interest and generating the location context information are executed automatically.
16. The mobile device of claim 13 , wherein the location context notifier is configured for selecting one of a plurality of points of interest according to at least one criterion by:
selecting one of the plurality of points of interest that is nearest to the current location of the mobile device.
