• a sensing means for collecting context information of each user;
• an intermediating means for changing the user context information transmitted from the sensing means into a request to store the request in a context recognizing means, transmitting the request to the context recognizing means, and transmitting a service request transmitted from the user to the context recognizing means;
• and
• a context recognizing means for storing context information of each user according to a context information storing request transmitted from the intermediating means, and providing a relevant service by using the user context information that the context recognizing means stores according to the service request transmitted from the intermediating means.
