In this paper, we present a perspective of the next generation mobile communication service and its characteristics. As a preliminary research work on the next generation mobile communications and services, we exploit the next generation mobile services. We define the next generation mobile services as strata of services consisting of three different service levels, the service areas, the service functionalities, and the service technologies. We derive these service levels by means of the scenario based analysis. Finally, we propose a conceptual network architecture that can support the next generation mobile services by placing network functions and service elements within the network.
