METHOD AND SYSTEM FOR PROVIDING SPATIAL-BASED CONTEXT-AWARE SERVICE
First Claim
1. An apparatus for creating a geocontext for a context-aware service, the apparatus comprising:
- a spatial region setting unit configured to set information regarding a space, in which the context-aware service is provided;
a diagram editor configured to provide interfaces defining input/out adapters needed to the geocontext for a context-aware service; and
a geocontext creation unit configured to create the geocontext including sensor data from sensors and a context catalog server, one or more contexts, spatial information set by the spatial region setting unit and input/output adapter.

Abstract
A system for providing spatial-based context-aware service includes a database configured to store a geocontext including spatial information, one or more contexts, and sensor data; a sensor/context catalog server configured to manage meta data of the contexts and the sensor data; a context processing server configured to generate a list of contexts applicable to the mobile device based on the sensor data and the meta data upon a receipt of the sensor data from the mobile device; a geocontext search server configured to search the database for candidate geocontexts appropriate for the user of the mobile device by using the location information of the mobile device and the list of contexts; and a context-aware management server configured to generate a list of recommended services by executing the searched candidate geocontexts.

14. A method for providing spatial-based context-aware service, the method comprising:
-
generating a list of contexts appropriate for a user by using meta data regarding sensors and contexts in accordance with a list of the sensors; generating a list of candidate geocontexts based on a current location of the user; executing the respective candidate geocontexts to generate a list of recommended services; and providing the list of recommended services to the user. - View Dependent Claims (15, 16, 17, 18, 19, 20)
