Intelligent transport systems. Vehicle interface for provisioning and support of ITS services. Unified gateway protocol (UGP) requirements and specification for vehicle ITS station gateway (V-ITSSG) interface | Status: Current, Under review

1 Scope This part of ISO 13185 specifies the requirements of an ASN.1-based protocol between a vehicle-ITS-Station Gateway (V-ITS-SG) and a nomadic and/or mobile device (ND) to easily exchange vehicle information data. The ASN.1-based protocol has been specified to support a wired or wireless connection between the ND and V-ITS-SG. The Unified Gateway Protocol (UGP) is used between the V-ITS-SG and the ND. UGP supports several features in order to provide

• — authorization (data privacy),
• — secured access,
• — V-ITS-SG and in-vehicle ECUs identification,
• — real-time vehicle data parameters with identifier and type information in ASN.1 format, and
• — enhanced vehicle data parameters with identifier and type information in ASN.1 format.
