Set of rules
Communication interfaces and applications are decoupled!
Based on rules and policies, functional requirements from ITS-S applications, and static and dynamic properties of communication interfaces, i.e. implementations of access technologies, ITS communication channels are assigned to ITS-S applications.

assigned to ITS-S applications.
Abstractions have to be used!
An ITS communication channel is defined by a mapping of an ITS-S application via a selected networking & transport layer protocol to the best suited communication interface. Some of these mappings may be static in a given regulatory domain, others will be highly dynamic, making best use of redundant and complementary access technologies by means of horizontal and vertical handover procedures.

• ...
→ Developers of base standards need a feed-back from experts on testing.
→ General approach for testing of SCITS and ITS needs to be developed.
→ General decision to use TTCN-3.
