本文件定义了通过P-ITS-S支持应急服务的用例和一般要求。任何与汽车相关的服务提供商都可以参考本文件，将eCall服务系统开发为eCall非支持性车辆。 P-ITS-S作为监控和数据传输设备，收集车速、碰撞和安全气囊展开信号，以评估事故发生和事故类型。一旦收集到的数据被确定为事故，事故相关信息将被发送到应急服务中心。 只有值得注意的事件，例如安全气囊- 本文件涉及已部署事件、翻车和静止事故。此外，应急服务的车辆数据采集设备要求和实施方法不适用于本文件。

This document defines the use cases and general requirements for supporting emergency services via P-ITS-S. Any automotive-related service providers can refer to this document for developing eCall service systems into eCall non-supportive vehicles. The P-ITS-S acts as a monitoring and data transmitting device which gathers a vehicle's speed, impact and airbag deployment signal to assess the accident occurrence and type of accident. Once gathered data has been determined as an accident, accident related information is sent to an emergency service centre. Only notable events, such as an airbag-deployed event, rollover and stationary accident, are concerned by this document. In addition, the vehicle data gathering device requirement and implementation methodology for the emergency service are not applicable to this document.
