In this paper, we present the ubiquitous services system that provides multimedia services, surveillance services and remote control services. This ubiquitous services system keeps the service session based on session initiation protocol (SIP) and supports the uniform interface for connecting the selected service to a suitable device by the operation of a general touch event. The service session of the ubiquitous services system is preserved even though an end-user moves from one computing environment to others. For getting the connected ubiquitous services, all that he has to do is to carry a small mobile pad, such as PDA or Cellular phone, which shows a list of devices that he can use as I/O devices of the on-going service session. He does not have to re-setup the session. When he clicks and selects the proper device among the devices listed on the pad, the session is immediately migrated to the selected device. In this paper, we describe the design of ubiquitous services system based on SIP and X.10 that supports both the user mobility and service session preservation in the ubiquitous wired/wireless network environment.
