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.
