31、Terrestrial Trunked RAdio (TETRA) as provided by European operators. Stage 3 defines the signalling system protocols needed to implement the service described in stage 1 and stage 2. The stage 1 and stage 2 aspects are detailed in EN 300 392-10-6 2 and EN 300 392-11-6 3 respectively. Aspects relatin
32、g to all supplementary services are detailed in EN 300 392-9 6. Charging principles and the Man Machine Interface (MMI) 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. 2 References The follow

40、OTE: This user is also able to activate/deactivate SS-CAD for other users (individuals and groups) within his responsibility area and interrogate the activation status for these users. restricted user: user whose calls are forced to be authorized by a dispatcher before the call can proceed NOTE: The
41、 restricted user can be either the calling user (A) or the called user (B) or both. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: ANF-ISIGC Additional Network Feature - Inter-System Interface Group Call ANF-ISISS Additional Network Feature - Inter-Sys

45、ned in EN 300 392-11-6 3, clause 4.1. These functional entities can, for one call, be located in different TETRA systems, refer to EN 300 392-11-6 3, clause 4. ETSI ETSI EN 300 392-12-6 V1.3.1 (2006-02) 9 4.2 Protocol structure and protocol stack SS-CAD PDUs shall be routed as specified in EN 300 39
46、2-9 6 (e.g. at the air interface in facility information elements for the call related SS-CAD PDUs and in U/D-FACILITY PDUs for the call unrelated SS-CAD PDUs, and using ANF-ISISS for conveying SS-CAD PDUs over the ISI). In addition some specific SS-CAD information elements have been included in the
47、 definition of some ANF-ISIIC and ANF-ISIGC PDUs. The present document is normative for the protocol architecture and user application Service Access Points (SAPs) within the MS/LS, but gives an informative description of the protocol within the SwMI. 5 SS-CAD service description 5.1 General This cl
48、ause describes the CAD specific services offered by the Circuit Mode Control Entity (CMCE) at the Supplementary Services Service Access Point (TNSS-SAP) of the TETRA Voice plus Data (V+D) layer 3 service boundary. The SS-CAD service access point may be used in conformance testing as a normative boun
49、dary in TETRA Mobile Stations (MSs) and TETRA Line Stations (LSs). NOTE 1: As the present document only deals with the SS-CAD all service primitives has been shown without a TNSS-CAD-prefix e.g. TNSS-CAD-ACTIVATE request is shortened to ACTIVATE request. NOTE 2: User application is the user of the supplementary service. 5.2 SS-CAD services offered over the TNSS-SAP The SS-CAD service primitives at the restricted user MS/LS (FE1) TNSS-SAP shall be: a) ACCEPTED indication; b) DIVERTED indication; c) REJECTED indication; d) INTERCEPTED indication.
