智能交通系统 - 用于配置和支持ITS服务的车辆接口 - 第3部分:统一的车辆接口协议(UVIP)服务器和客户端API规范
This document specifies the server and client APIs of the Unified Gateway Protocol (UGP). Figure 1 shows an overview of the UGP client and server API. A UGP client application on a P-ITS-S communicates with a UGP server application on a V-ITS-S. The UGP client application implements the UGP client API using ISO 13185-2. The UGP server application implements the UGP server API using ISO 13185-2.
