摘要
车载紧急救援呼叫系统在车辆遇到碰撞事故、严重故障时可以自动或手动通过蜂窝网络建立与接警指挥中心的话音连接并传送车辆位置信息。这一系统的推行将有利于节省救援时间,保障公民安全。本文介绍了一种通过带内调制的方式在语音业务信道传输位置信息的车载紧急救援呼叫系统结构。随着Vo LTE技术的发展,车载紧急救援呼叫系统未来也将拥有更好的性能。
The e-Call system can automatically or manually establish a connection with public safety access point via the traffic channel of cellular network as well as uploading the location information, when encountering a collision or a serious breakdown. The implementation of this system will be of great help to save time for rescuing and protect the security of citizens. This paper introduces a structure of in-band modulation e-Call system which transmitting location information in a traffic channel. With the development of Vo LTE, e-Call system will have a better future performance.
