¿µ¹®³»¿ë¿ä¾à 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.
