Apparatus and method for providing context-aware service

Abstract

An apparatus and method for providing a context-aware service are provided. The apparatus includes a context-aware service object (CAS) management module managing information on a CAS and a context defined by the CAS, a sensor management module managing information on a sensor and requesting the sensor to observe knowledge, and a context management module informing the CAS management module of a CAS defining a context provided by the CAS management module when observed knowledge satisfies the context defined by the CAS, wherein upon being informed of the CAS by the context management module, the CAS management module requests the CAS to provide a service.

Description

technical field [0001] The present invention relates to a device and method for providing context-aware services, and more specifically, to a device and method for providing adaptive services by providing a context-aware service framework (framework) according to dynamically changing contexts. The content of services in the service framework is determined by knowledge. Background technique [0002] The main middleware supporting application software is object-oriented middleware. In conventional object-oriented middleware, a client object obtains an interface to use a service from a server object and uses the server object through the obtained interface. [0003] Figure 1 shows the concept of a conventional and representative object-oriented middleware, that is, Common Object Request Broker Architecture (CORBA). [0004] CORBA is a structure and standard for generating, distributing and managing distributed program objects in a network, and CORBA a...
