These days, vehicle is evolving from the isolated space of transportation to the third digital life space connected to the information world via wired and wireless internet and in which the various activities are possible. According to this trend, the speed of growth in the development of Telematics technology and standard is being accelerated due to the government's IT839 strategy and market needs in Korea. ETRI, TTA, and the Telematics Standardization Forum play key role in developing domestic Telematics standard of core technology needed by industry in relation with each other. The international standards are mainly developed by de-facto standardization organizations such as OSGi, OMA, ERTICO, etc. currently. In this paper, we discuss the trends and issues in Telematics standardization and future strategy.

Telematics is a kind of the convergence of industries such as an automobile, communication, contents, and so on. Jeju-Do has been selected as a model city for telematics and has carried out the telematics service project. Jeju Telematics contains six service areas including navigation, traffic information, emergency assistance, leisure information, tour destination information, and cultural life information. Jeju telematics project has been planned to be dealt with the aspects of technological skills and content development. In fact, because of the nature of model project for testing information technologies, Jeju telematics has been strongly approached by technical aspects. However, telematics is composed of services for users. Then, the success or fail of telematics project can be dependent upon the demand of users, and, in general, users are influenced by the contents of services. Thus, the contents of services should be also dealt as a major concern in the telematics project. In this sense, the purpose of this study is to examine the degree of recognition and preference of contents by users about telematics service. Examination is proceeded by a survey method. Based on the result of the survey, this paper proposes the alternatives for the future directions of Jeju Telematics project regarding contents.

The telematics positioning testbed is an infrastructure to test and verify positioning technology, the sub-component of telernatics system. The positioning testbed provides the environment of performance analysis for acquisition of static and dynamic positioning information using telematics vehicle. This testbed consists of onboard positioning system, positioning reference station and lab positioning server. The onboard positioning system equipped in telematics vehicle, consists of target positioning system, reference positioning system, and analysis tool. A equipment acquiring high precision positioning data obtained from GPS combined with IMU was set as a reference positioning system. Analysis tool compares observed positioning data with high precision positioning information from a reference positioning system, and processes positioning information. Positioning reference station is RTK system used for reducing atmosphere error, and it transmits corrected information to reference positioning system. Positioning server which is located at laboratory manages positioning database and provides monitoring data to integrated testbed operating system. It is expected that the testbed supports commercialization of telernatics technology and services, integrated testing among component technology and verification.

It is evident that advancement of ubiquitous technologies in the near future guarantees more convenient and plentiful living. With regarding to car life, we dream of an automatic driving without any effort of operation. This paper touches the realization issue, a convergence of wireless sensor network and Telematics specializing on an information routing mechanism between participating components in Telematics sensor communication network. We list up new requirements of wireless sensor network deployed for Telematics services. Then context-aware routing architecture is proposed in order to solve these constraints, in which a network topology for routing can be dynamically configured according to the combination of context models of network components.

Recently, automobile industry expands from mechatronics area through intelligent information area, and the telematics technology is one of the greatest developing points. The telematics is utilizing the on-board-unit of vehicle's communication system, and it provides necessary information and value-added service to vehicles as well as drivers. Most of the telematics offers the solution of searching a route or generates an optimal path. This paper investigates telematics with the logistics point of view, such as freight location tracking, vehicle emergency information, etc. The telematics is a core technology of automobile industry, and it becomes new business paradigm of IP(information provider). Especially, ETA(estimated arrival time) of freight and distribution tracing information are critical issues in the logistics industry. The successful integration with telematics is introduced in the paper.

Recently, as technology for obtaining locational awareness and wireless telecommunications improve, technologies and services involving Telematics has grown rapidly. However, the services are currently available on certain terminals selected by the telematics service provider (TSP). This means in order to access services provided by other TSPs, it is necessary to purchase related terminals. To solve this problem, it is essential to achieve service interoperability between TSPs, or between TSPs and the contents provider (CP). Under this backdrop, the aim of this paper is to design and implement a telematics service framework for openning services in a heterogeneous network environment. Futhermore, the paper presents open telematics protocols required for communication in the telematics service framework, and develop technologies to deal with this in different network environments.

In this letter, we analyze the problems with the existing telematics service systems that have been dependently developed and provided on a specific mobile network infrastructure. Then, we suggest methods to solve the problems and propose an architecture of the gateway and framework to implement our methods. We also verify the effectiveness of the suggested architecture through a comparison with an existing telematics system. With this architecture, it is possible to develop service applications without knowledge of the underlying mobile network technology and the system integration methods.
