Standardization activity on user centric space

User-Centric work Space (UCS) service provides a user with a personalized (user-centric) work space by orchestrating local and/or remote IT resources (such as file, printer, monitor, keyboard and more). With UCS service, various mobile devices such as smart phone can create personalized and secure work environment for user, because it can store and process user data in secure manner without the interference from the external environment. During the Nov. 2013 ITU-T SG13 meeting, a new standardization activity on UCS has started. With this paper, we describe the conceptual model of UCS, related standardization activity, and some of use cases to present User-Centric work Space (UCS) services.
