Follow-Me Services Framework using the Session Initiation Protocol

摘要

In this paper, we present the follow-me services framework that provides connected ubiquitous services. This follow-me services framework keeps the service session based on Session Initiation Protocol (SIP). The service session of the follow-me services framework is preserved even though an end-user moves from one computing environment to others. For getting the follow-me 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 follow-me services framework based on SIP and X.10 that supports both the user mobility and service session preservation in the ubiquitous wired/wireless network environment.
