Composite context information management apparatus and method of providing composite context information using the same

A composite context information management system comprising:

• a user terminal configured to, in response to an application being executed, detect occurrence of pieces of unit context information and perform a particular operation corresponding to a composite context which is generated by performing an operation on the pieces of unit context information;
• a composite context information management apparatus configured to receive is information about the application from the user terminal and provide information about the composite context to the application;
• an application control unit configured to receive information about an application to be executed in the user terminal and transmit a name of composite context information required for executing the application and operation information regarding an operation of the application;
• a function providing unit configured to provide a composite context information function corresponding to the operation information from the application control unit;
• a composite context information processing unit configured to extract and process pieces of unit contexts and an operation rule which are included in the composite context information based on the name of the composite context information and the composite context information function which are received from the application control unit;
• and
• a composite context information presence unit configured to store the pieces of unit contexts corresponding to the name of the composite context information and an instance value for identification of the application and, in response to the application being executed in the user terminal, transmit composite context information generated based on the pieces of unit contexts and the operation rule to the user terminal.

A method of providing composite context information corresponding to a result of performing an operation on pieces of unit context information using logical operators in a user terminal, the method comprising:

• receiving an application from the user terminal;
• receiving a function corresponding to the application and acquiring at least one of pieces of unit context information required for the composite context information by using a name of the composite context information required for a function requested by the application;
• and
• transmitting the acquired information from the application corresponding to an instance value for identification of the application.
