导航数据传送结构与协议

[中文适用范围]： 该国际标准定义了智能交通系统（ITS）应用程序中使用的数据结构和协议，用于从服务中心（SC）向用户[（车载系统（IVS）]交付和更新地图相关数据。 本国际标准还规定了服务中心的消息生成协议和车载系统的消息接收协议，本国际标准规定的地图中心代表地图数据的提供方，服务中心向用户设备提供数据和服务本国际标准中使用的术语“协议”是实现地图相关数据传递和更新的系统组件之间地图相关数据交互的时间序列。 地图相关数据的传递和更新依赖于现有的通信技术。 与通信技术相关的其他应用控制协议和非地图相关数据（例如独立于地图数据库显示的图像（如 HTML 图像））不属于本国际标准的范围。 安全机制和业务事务机制的定义也不属于本国际标准的范围。 下图 1 说明了本国际标准的范围。 [外文原描述]： ISO 24099:2011 defines the data structures and protocol(s) used in intelligent transport system (ITS) applications for the delivery and update of map-related data from Service Centre (SC) to users [(In-vehicle Systems (IVS)]. ISO 24099:2011 also specifies the message generation protocols in the Service Centre and the message receiving protocols in the In‑vehicle Systems. The map centre specified in ISO 24099:2011 represents the supplier of map data and the Service Centre provides data and services to user devices. The term protocol as used in ISO 24099:2011 is a temporal sequence of map-related data interactions between system components that implement map-related data delivery and update. The delivery and update of map-related data rely on existing communication technology. The protocols associated with communication technology, and the other application control protocols and non-map-related data, for example images to display independent of the map database such as HTML images, are outside the scope of ISO 24099:2011. Definitions of security mechanisms and business transaction mechanisms are also outside the scope of ISO 24099:2011.
