ADAPTATION QOS MIDDLEWARE SYSTEM AND METHOD SUPPORTING SERVICE IN ADAPTATION QOS MIDDLEWARE SYSTEM

An adaptive QoS(Quality of Service) middleware system and a service supporting method in the system are provided to realize adaptive QoS middleware to support multimedia applications in ubiquitous environment, thereby adaptively ensuring QoS by considering a user's mobility as more effectively expressing/processing a lot of context information around the user. A context service module(110) collects contexts from various sensors(10) to analyze the contexts, notifies random applications(20) of the analyzed results, and confirms a user's mobility through the analyzed results. A QoS management service module(120) sets new QoS setup information using information of a host used by the user and initial QoS setup information, and executes QoS for the current session. A user mobility service module(140) receives information on the user's mobility, perceives the information of the host to which the user moves to send the perceived information to the service module(120), and performs session handoff with a client of the host. A multimedia service application interface module(150) receives context changes and controlled QoS information and session information to notify the applications(20) of the received information.
