Описание
The present document defines the stage 2 specifications of the Supplementary Service Call Authorized by Dispatcher
(SS-CAD) for the Terrestrial Trunked Radio (TETRA) as provided by European operators. Stage 2 identifies the
functional entities involved in the supplementary service and the information flows between them. Stage 2 is part of
three stage definition where stage 1 (EN 300 392-10-6 [1]) specifies the service description and the procedures of the
supplementary service and stage 3 specifies the service primitives, PDUs and protocols for functional entities.
NOTE: The stage 2 description is followed by the stage 3 description EN 300 392-12-6 [2], which specifies
the encoding rules for the information flows and process behaviour for the different entities in the SwMI,
in the MS and in the LS.
Aspects relating to all supplementary services are detailed in EN 300 392-9 [7].
Man-Machine Interface (MMI) and charging principles are outside the scope of the present document.
The SS-CAD ensures that predefined TETRA calls do not proceed without first being authorized by a dispatcher.
