Abstract:
Provided are a vehicle terminal apparatus and a method for controlling the apparatus, which receives vehicle location information, registers a service based on service notification information after receiving the service notification information from a traffic signal controlling apparatus, and extracts traffic information based on the vehicle location information.
Abstract:
PURPOSE: A vehicle information transmitting method, a vehicle information receiving method thereof, and a system performing the same are provided to effectively transmit vehicle information between a vehicle gate way and an information terminal. CONSTITUTION: An authentication server(300) performs an authentication process about an information terminal(200). When authentication succeeds, the authentication server transmits authentication code information including an authentication code, an access level and validity period information to the information terminal. A vehicle gateway(130) authenticates the information terminal based on the authentication code and the validity period information.
Abstract:
PURPOSE: A method and an apparatus for storing black-box data based on a flash memory are provided to store user information and vehicle information except driving information, thereby easily examining a cause of an accident. CONSTITUTION: A telematics terminal(150) receives vehicle information from one or more detecting devices. An information classifying device receives the vehicle information from the telematics terminal. The classified information identifies the kind of the received vehicle information. A volatile memory stores the vehicle information in an information storage area allocated to the identified kind. A nonvolatile memory stores the vehicle information saved in the information storage area.
Abstract:
An alarm apparatus and a method for prevention of car accidents are provided to prevent a car accident effectively by classifying a danger into a grade and alarming it by the grade. Information collecting units(110,120,130) collect an internal state of a traveling vehicle, an environment condition, and a traffic condition in real time. A danger determination unit(170) compares the internal state and the environment condition with reference information and determines the danger. If the danger grade is higher than the reference grade, an urgent situation alarm unit(190) transmits urgent alarm to surrounding vehicles and a display unit(180) outputs a warning message corresponding to the danger grade.
Abstract:
차내망 게이트웨이가 설치된 차량의 정보를 수집하는 차량 정보 수집 장치는 인식부, 에이전트 엔진 및 전송부를 포함한다. 인식부는 차량의 진입을 인식한다. 에이전트 엔진은 차내망 게이트웨이로부터 차량의 정보를 수집하고, 차량의 정보를 공통의 형식으로 변환하여 변환된 차량 정보를 생성한다. 또한, 전송부는 변환된 차량 정보를 서버로 전송한다. 이로써, 차량 정보 수집 장치는 서비스 제공자들이 차량정보를 보다 용이하게 수집하여, 지능화된 차량 정보 제공을 통해 운전자 편의 증진 서비스를 제공할 수 있다. SNMP, VIGD, MIB

Abstract:
PURPOSE: A method of setting an expanded label switching path in an MPLS(Multi Protocol Label Switching) system is provided to set an expanded label switching path up to an MPLS area from a forwarding engine mounted in a specific port of an ATM exchange, thereby improving a system performance. CONSTITUTION: An MPLS LER(Label Edge Router) sets a label switched path(401). In an MPLS area, a label switched path setup is performed by a label distribution protocol. When the label switched path is set, the MPLS LER decides an operation mode of the set path(402). If the operation mode operates in an ingress mode, the MPLS LER confirms whether a preset subscriber PVC is connected(406). If so, the MPLS LER registers a forwarding entry for an ingress connection(407), and transmits the registered forwarding entry to a forwarding engine(408).
Abstract:
PURPOSE: A method for setting an expansion label switched path in a multi-protocol label switching system that includes Internet protocol packet forwarding engines is provided to set a label switch path and the expansion label switched path in a switching center. CONSTITUTION: The expansion label switched path generated in each Internet protocol packet forwarding engine is connected to multi-protocol label switching areas(LC-ATM_1 - LC-ATM_n) in one of label switched switching centers. The expansion label switched path, which is connected to the multi-protocol label switching areas(LC-ATM_1 - LC-ATM_n) in a certain label switched switching center, is connected a label switched path that is coupled with the certain label switched switching center.
