bounded secured managed domain that is able to meet requirements of the ITS trust domainwithin which it wishes to participate
NOTE 1 to entry: The ITS station reference architecture is defined in ISO 21217.
functional entity comprised of an ITS-S facilities layer, ITS-S networking & transport layer, ITS-S access layer, ITS-S management entity, ITS-S security entity and ITS-S applications entity providing ITS services
NOTE 1 to entry: From an abstract point of view, the term “ITS station” refers to a set of functionalities. The term is often used to refer to an instantiation of these functionalities in a physical unit. Often the appropriate interpretation is obvious from the context. The proper name of physical instantiation of an ITS-S is ITS station unit (ITS-SU).
