Development of real-time enterprise communication service for ubiquitous age

Smart terminals such as cellular phones and PCs and sophisticated network technologies such as cellular communications and Internet Protocol (IP) can be used to build network service platforms that can change the style of everyday work and create new value for customers. One of the new services to come from such a platform is a high-mobility service that enables people to continue working over a network while traveling. Another is a collaboration service that exchanges voice, video, and other information between different locations. In addition, a ubiquitous service that enhances connections over a network will be provided in the near future. This paper introduces three new network services that enable business to be done more efficiently: a service that connects cellular phones to an enterprise network, a Web-based multimedia videoconference system, and an experimental ubiquitous service that associates Quick Response (OR) codes with cellular phones.
