PROPAGATION METHOD OF EMERGENCY MESSAGES BY HETEROGENEOUS NETWORK ROAD-SIDE WQUIPMENT IN INTELLIGENT TRANSPORT SYSTEM

摘要

In an intelligent transportation system, an emergency message delivery method is provided. In the intelligent transportation system according to the present invention, an emergency message delivery method of a multi-base station transmits an emergency message of a first WAVE OBE to a roadside equipment providing a WAVE service, and transmits the emergency message to a service area of a first roadside station. The emergency message of the first WAVE OBE is transmitted to a heterogeneous OBE that is different from the WAVE and uses heterogeneous communication, and the emergency message of the first WAVE OBE is transmitted to the second roadside base station adjacent to the first roadside base station. The process of transmitting. According to the present invention, an emergency message transmitted by a WAVE-based terminal can be transmitted to a heterogeneous terminal other than the WAVE.;Car black box, WAVE (Wireless Access for Vehicular Environment)
