Terrestrial Trunked Radio (TETRA); Voice plus Data (V+D); Part 12: Supplementary services stage 3; Sub-part 6: Call Authorized by Dispatcher (CAD)
The present document defines the stage 3 specifications of the Supplementary Service Call Authorized by Dispatcher (SS-CAD) for the 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 relating 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.

1 Scope
The present document defines the stage 3 specifications of the Supplementary Service Call Authorized by Dispatcher
(SS-CAD) for the 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 relating 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.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
authorized user: user who can make service definition
NOTE: The authorized user can also activate/deactivate and interrogate the service.
dispatcher: user to whom the request for authorization shall be directed to. 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. The restricted
user can be either the calling user (A) or the called user (B) or both.

4.1 Functional entities and communication routes
The functional model for SS-CAD consists of Functional Entities FE1 to FE5 as defined 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.

4.2 Protocol structure and protocol stack
SS-CAD PDUs shall be routed as specified in EN 300 392-9 [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 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 clause 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 boundary 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.
The SS-CAD service primitives specific at the authorized user MS/LS (FE3) TNSS-SAP shall be:
a) DEFINE request;
b) DEFINE indication.
The SS-CAD service primitives at the authorized user MS/LS (FE3) and dispatcher (FE7) TNSS-SAP shall be:
a) ACTIVATE request;
b) ACTIVATE indication;
c) DEACTIVATE request;
d) DEACTIVATE indication;
e) INTERROGATE request;
f) INTERROGATE indication.

The SS-CAD service primitives specific at the dispatcher (FE7) TNSS-SAP shall be:
a) ACCEPT response;
b) CANCEL indication;
c) DIVERT response;
d) REJECT response;
e) REQUEST indication.
NOTE: Following service primitives assume that a call identifier or equivalent information is exchanged
implicitly or explicitly with the primitive, when the primitive is related to a call.
5.2.1 ACCEPT response
The user application shall offer an ACCEPT response to the dispatching user MS/LS (FE7) to indicate that the call has
been authorized. The only parameter for this primitive is an optional Access priority.
5.2.2 ACCEPTED indication
The calling user MS/LS (FE1) shall offer an ACCEPTED indication to the user application to inform that the call
authorization is successfully completed. There are no parameters for this primitive.
5.2.3 ACTIVATE
