Summary

A vehicle gateway (VG) is a device in a vehicle that enables communications between a device in the vehicle and another device which may be physically located either inside the vehicle or outside the vehicle.

Recommendation ITU-T F.749.1 describes functional requirements for vehicle gateways, including transport functional requirements, networking functional requirements, network access functional requirements, communication with in-vehicle devices functional requirements and network access management and security functional requirements. This Recommendation also describes the network protocols and communications interfaces to support seamless wired and wireless connectivity in heterogeneous access network environments.

This Recommendation specifies functional requirements for a VG supporting a variety of existing and new access technologies. The VG is to a large extent independent from specific communication technologies and specific intelligent transport system (ITS) applications. The VG architecture is intended to be an open architecture, which will make it easy for a manufacturer to implement, test and select an appropriate communications type according to the manufacturer's own requirements and network conditions.
