This paper identified some problems of original UCON model: it lacked the ability to handle actions after the usage of the resources in a specific session,oversimplified the concept of usage session and there was not a comprehensive enforcement mechanism considering its decision continuity and attribute mutability properties.For these problems,extended the original UCON,presented a comprehensive obligation model and finally proposed a general usage control enforcement model.
