Is there a definition (a standard) of an URN scheme for tetra devices? (TETRA as Terrestrial Trunked Radio)
I found many pages about the SSI and ITSI (individual Tetra subscriber identity) but nowhere a URN scheme for that. Would be nice if there is already some standard for it so i dont have to define one myself.
No.
All URN namespaces are registered on http://www.iana.org/assignments/urn-namespaces. There doesn’t seem to be one for TETRA.
