Abstract

Many context-aware systems have been demonstrated in lab environments; however, due to some difficulties such as the scalability and privacy issues, they are not yet practical for deployment on a large scale. This paper addresses these two issues with particular interest in user's privacy protection and spontaneous system association. A person-centric service infrastructure is proposed together with a context-aware call forwarding system constructed as a proof-of-concept prototype based on the Session Initiation Protocol (SIP).
