Service Creation Trial based on Wireless Ubiquitous Network

The wireless ubiquitous network and various services are expected to be realized widely. In this paper, the wireless ubiquitous network is defined as the converged network to integrate the mobile wireless network with the fixed IP based network including various access technologies like WLAN/WPAN. First, the wireless ubiquitous network architecture is shown which is based on IMS (IP multimedia subsystem) standardized by 3GPP. IMS provides a mean that integrates heterogeneous network into an IP based network enabling wireless ubiquitous network. Next, Parlay which is also standardized by 3GPP is described to create the various services. Then the service creation trail is shown including the trail system configuration and vehicle dispatcher service as an example
