Position-based context awareness for mobile terminal device

摘要

The present invention relates to location/position-based context awareness for devices and mobile terminal devices, respectively. In particularly, the present invention relates to an infrastructure entity performing the location/position-based context awareness for a portable terminal device. According to the present invention an infrastructure entity and a method operable therewith for serving distance-dependent context information relating to a defined environment is provided. For instance, terminal/object distances are determined in accordance with a position of a portable terminal, each position of a plurality of objects and a position of an infrastructure entity, which is adapted to serve the aforementioned distance-dependent context information. Context information, which is associated with each of the plurality of object, is provided for being selected. Context information is selected from provided context information on the basis of the determined terminal/object distances. The selected context information is finally transmitted to the portable terminal for being processed thereon.

主权项

1. A method comprising:
causing, at least in part, on an apparatus, storage of context information associated with a predefined environment that is associated with the apparatus, wherein said apparatus handles said context information, and said context information is centrally administered by a central server: determining a position of a mobile terminal device when said mobile terminal is located within a coverage area of said apparatus; selecting said context information in accordance with said determined position and said predefined environment associated with the apparatus; causing, at least in part, a transmission of said selected context information to said mobile terminal for being processed thereon; and providing a plurality of objects, wherein each object is associated with said context information, wherein each object has a position, which is defined with reference to said defined environment, wherein each of said terminal to object distances comprises one out of a group of distance quantities including:
(a) a distance between said position of said mobile terminal and each position of said plurality of objects; and(b) a distance between said position of said mobile terminal and said position of said apparatus.
