Various wireless and wired terminals have been well developed, but there are big differences between a compact mobile phone and a desktop PC connecting to the high-speed Internet, on their performances and qualities. If we could switch among those different terminals adaptively according to availability, quality, cost and usability, the most appropriate terminal can be always used. In the ubiquitous network environment, various sensors and actuators will be connected to the networks and new communication services are expected to come out. As a new communication service candidate, in this paper, we show cross-device handover technology which switches an on-going multimedia communication session from an actuator to another actuator. We also show a context sensing platform for providing context-aware services to the mobile users. We realize a ubiquitous network application that the sensors collect the user's current information, a server in the network estimates the user's context, and appropriate information is provided to the user by the optimum way according to the contextual information.
