WPAN Platform Design in Handset Integrating Cellular Network and Its Application to Mobile Games

Various network technologies have been developed towards ubiquitous computing. Actually, the specific network technology has its own protocol layer, characteristics and objectives. Due to these limitations, though cellular network and WPAN are being used in handset together, the services using both networks are not so popular until now. This paper presents a platform design integrating cellular network and WPAN and its application to the mobile game service. To develop services and applications which utilize cellular network and WPAN, we discuss the WPAN platform for handset. Various aspects are considered on the connection, which can expand the area of mobile services and applications. An illustrative application of this platform is introduced as a mobile game service. In the proposed game service, downloading games or game items, managing players, etc. are provided using cellular network. The actual game traffic between players utilizes WPAN. As shown in the proposed game service design, various applications are being expected through the WPAN platform.
