Development of portable intelligent gateway system for ubiquitous entertainment and context-aware services

In this paper, we propose a Portable Intelligent Gateway System (PIGS) which allows seamless network access through heterogeneous network interworking for the seamless device-independent multimedia services for multi users. In addition, it provides ubiquitous multimedia push services and entertainment services according to the autonomous reconfiguration of devices. Furthermore, our system manages the dynamic events and various embedded sensors by interworking with ubiquitous service domains.
