SYSTEM AND METHOD FOR PROVIDING FLEXIBLE CONTEXT-AWARE SERVICE
First Claim
1. A method for providing flexible context-aware service (CAS), the method comprising the steps of:
- (a) registering at least one context-aware service (CAS);
(b) determining whether sensors associated with the CAS are registered;
(c) when all the sensors are registered, checking all contexts associated with the CAS;
(d) upon receipt of a CAS request, receiving context information from the sensors and determining whether the context information satisfies the contexts; and
(e) providing the CAS if the context information satisfies at least one of the contexts.

Abstract
Provided are a system and method for determining whether to provide service and a content of the service based on ubiquitous-based context information. The method includes the steps of registering at least one context-aware service (CAS); determining whether sensors associated with the CAS are registered; when all the sensors are registered, checking all contexts associated with the CAS; upon receipt of a CAS request, receiving context information from the sensors and determining whether the context information satisfies the contexts; and providing the CAS if the context information satisfies at least one of the contexts. With the flexible engine determining whether to provide service corresponding to a current context even though all context information constituting the CAS is not collected, information is quickly provided upon receipt of a service request from a user.

8. A system for providing flexible context-aware service (CAS), the system comprising:
-
a flexible CAS estimation engine for determining that a client-requested CAS is to be provided if context information from sensors satisfies at least one of the contexts; and a context-aware server for allowing the flexible CAS estimation engine to determine whether to provide the CAS upon receipt of a CAS request from the client, and providing the CAS to the client depending on the determination. - View Dependent Claims (9, 10)
