The present invention relates to an apparatus and method for dynamic session management of a knowledge-based home network service in a ubiquitous environment, and more particularly, to select a service suitable for a user according to a sensor value (user identification information) according to a user's movement. In addition, it extracts collision information and error information by performing policy situation verification on the selected service, and obtains service provision information directly from the inference engine through a query generation engine and provides the corresponding service bundle to dynamically manage each service. The present invention relates to an apparatus and method for dynamic session management of a knowledge-based home network service in a ubiquitous environment for resolving contention, collision, and policy issues, and to improve scalability and management efficiency for multiple services.

Ubiquitous environment refers to an environment in which a user can freely access a network and receive various services regardless of a place without a computer or a network.
