Trial of communication services based on wireless ubiquitous network

The wireless ubiquitous network and various communication services are expected to be realized. The wireless ubiquitous network is defined as the converged network to integrate the mobile network with the fixed IP based network. First, the concept of wireless ubiquitous network architecture is shown which is based on IMS standardized by 3GPP. Next, Parlay is described as the solution of Open API approach to implement the communication services. Then the field data collection service is described as an example of communication service based on the sensor network in the field.
