IMPLEMENTATION AND EVALUATION OF MOBILE NETWORK PLATFORM FOR HIGHLY RELIABLE COMMUNICATIONS ON SMART GATEWAY

As ITS services, the Vehicle Information Control System (VICS) and Electronic Toll Collection system (ETC) have already been put into service and their application services are being deployed in various fields. At the same time there has been a rapid proliferation of the Internet, which is promoting global development of network services. One of the features of the development of our vehicular society is that on-board vehicle terminals are becoming a successor to regular cellular phones carried by people. Technological development is being carried on as a national project in Japan to establish information and communication network technology that supports user mobility (called the "Smart Gateway" for the future vehicle/road communication system) to implement a variety of information services aimed at safe driving. The authors have proposed a mobile network platform to implement highly reliable communications on the Smart Gateway. This paper reports on the study of the implementation method and scope of the ITS mobile network based on its network requirements. To access the mobile network, this paper proposes roadside network control based on autonomous decentralized control using Dedicated Short Range Communication (DSRC) as well as gateway control to provide on-board vehicle terminals with IP service through inter-working with wide-area IP networks. As the implementation method of the roadside network control, the paper reports on the "microcell mobility management system" for continuous communication in mobile environment. This function provides high-speed and high-response transfer of packet data within the network to provide uninterrupted continuous communications across radio links and the high-speed data transfer function in mobile environment by guaranteeing transferred packet data. The paper also reports on the implementation method of the "protocol to provide IP and non-IP applications" for gateway control. This method refers to provisioning of unified and efficient API (Applications Program Interface) that is independent of individual specifications for each application. This paper also reports on the "evaluation of the applicability of DSRC specifications" which define the access infrastructure of the ITS mobile network platform.
