Intelligent gateway systems have evolved to seamlessly offer location-aware and multimedia services, allowing multi users to roam among multi service domains. In the past decade intelligent gateways have been implemented to support context-aware multimedia services with network convergence and service reasoning mechanisms in multi domains. However, recent researches have to consider multiple events and service management according to the user's movements and requirements. Therefore, we propose a Portable Intelligent Gateway System (PIGS) to offer seamless device-independent multimedia services and location-aware push services. Using heterogeneous network convergence and utilizing cooperation between other gateways, the PIGS interconnects users (user devices) who want to be offered multimedia services and Service Providers (SPs). Furthermore, our system dynamically offers differential services to multiple users with respect to the user, device and location characteristics. The PIGS also collects events using embedded sensors and generates events used for service configuration along with service predictions by using light-weight middleware. In this paper we implement real testbed, a house and a car, and verify the effectiveness of the service reconfiguration. The portable gateway structure using the PIGS achieves a 22% faster service response time in comparison to a fixed gateway-based structure.
