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.
NOTE This document does not define the UGP client and server API in other languages than Java.
