The advance of mobile and telematics technologies has produced vehicles with various convenient services for drivers. Specifically lots of researches and several technologies have been developed to provide services of a remote vehicle diagnosis and control. The existing and representative product for a vehicle control is a RCS (remote control system), but it has a problem of short control distance and fragile security. In this paper, a telematics terminal embedded with CDMA and GPS is designed, which can be connected to the Internet. It allows a driver with a cellular phone to remotely diagnosis and control a vehicle via wireless network and SMS.

In this paper, for supporting more variable services than typical DSRC, brand call service, truck and an official vehicle services, etc. using location information and mobile communication network could be adapted. emergence helping information providing, multimedia service that are wireless internet, movies and games, are increasingly needed for competible wireless car mobile terminal. Those needs would make a development a wireless telemetries system based on WiBro interface in ubiquitous vehicle environment. We analysis the proposed telematics mobile terminal using simulation which is concerned about fixed bandwidth and dynamic bandwidth.

The advanced technology called Telematics appeared with the development of automobile industries and IT technologies. In Telematics it is important to offer good quality information to the car which loads the terminal, so in this paper, for this, we propose the intelligent information service method using artificial intelligence(A. I.). In this paper, through the concept of multi-agent, we represent Telematics system and show the interaction between information service center and a terminal for smooth information service. Finally, we mention the way that Telematics should persue for the enhancement of information service.

This paper attempts to conceptually examine the factors affecting the growth potential of WiBro in the Korean communication market. The results of the paper implies that the WiBro service operators' business intentions mainly affect the its diffusion negatively and the convergence service combining WiBro with other heterogeneous service including Telematics services might enable WiBro to successfully grow compensating the current limitation of WiBro.

As the need for telematics contents services due to the frequent traveling of people is increasing, it is necessary to provide various telematics contents by connecting and integrating current telematics contents which are collected and provided by each individual data provider. However, it is difficult to integrate or exchange the current telematics contents, because the data providers use different telematics contents models. Therefore, we propose a 'telematics contents gateway(TCG); system, which enables to integrate different telematics contents, so that the contents can be interoperable. The TCG can be a solution for several problems in the current telematics contents providing system. First of all, it has been impossible to search the contents without any information about data providers, because of the absence of metadata in the current systems. For this problem, TCG supports a search function based on a web-service technology. Second, TCG provides a common road network model for interoperability, and the model can be a solution to integrate different road network models into the common model. Moreover, integration algorithm for enhancing the correctness of integration will be proposed. In addition, it is designed by multi threads and multi queue structure. The TCG developed with C# on a windows system has been running and we verified that there was no information loss in the integration process. In addition, the speed of content integration and transfer satisfied the requirement of telematics services providers.

In this paper, we implement the Digital Signal Processing System based on Human Machine Interface technology for the telematics with embedded noise-robust speech recognition engine and develop the communication system which can be applied to the automobile information center through the human-machine interface technology. Through the embedded speech recognition engine, we can develop the total DSP system based on Human Machine Interface for the telematics in order to test the total system and also the total telematics services.

텔레매틱스는 차량내의 무선 통신을 이용하여 텔레매틱스 서비스 센터(TSP)로부터 차량 단말를 통해 차량과 운전자에게 유용한 다양한 정보 및 서비스를 제공한다. 하지만 텔레매틱스 단말 장치는 온도, 잡음 등 열악한 차량 환경에서도 운용할 수 있는 특수한 임베디드 시스템으로 구성되어 있다. 또한 그 시스템에 맞는 전용S/W플랫폼으로 구성됨으로써 텔레매틱스 컨텐츠간의 상호 운용성이 보장되지 못하는 실정이다. 본 논문에서는 텔레매틱스 기술 개발 과제의 일환으로 개발된 텔레매틱스 단말 응용 미들웨어를 소개한다. 이 미들웨어는 개방형 기술인 자바를 기반으로 하여 컨텐츠간 상호 운용성을 보장하고, 컨텐츠 개발을 용이하게 하기 위해 표준화된 인터페이스를 제공한다.

In the ubiquitous computing environment, a ubiquitous vehicle will be a communication node in the vehicular network as well as the means of ground transportation. It will make humans and vehicles seamlessly and remotely connected. Especially, one of the prominent services in the ubiquitous vehicle is the vehicle remote operation. However, mutual-collaboration with the in-vehicle communication network, the vehicle-to-vehicle communication network and the vehicle-to-roadside communication network is required to provide vehicle remote operation services. In this paper, an Internet-based human-vehicle interfaces and a network architecture is presented to provide remote vehicle control and diagnosis services. The performance of the proposed system is evaluated through a design and implementation in terms of the round trip time taken to get a vehicle remote operation service.

In location-based services, most trigger technologies have been implemented on the server side by periodically requesting the locations of mobile phones from mobile network servers. However, bottlenecks and communication interruptions occur when the servers are overloaded by trigger requests. In this letter, we propose a new multilevel location trigger specification which distributes the event detecting role to mobile phones and redesigns the location triggering into a multilevel step. Our suggested location trigger specification can reduce bottlenecks caused by triggers in a mobile core network and reduce power consumption caused by embedded GPS devices in mobile phones.
