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 300392-9 [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. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. • References are either specific (identified by date of publication and/or edition number or version number) or non-specific. • For a specific reference, subsequent revisions do not apply. • For a non-specific reference, the latest version applies.

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 NOTE: 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 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-System Interface Supplementary Service CAD Call Authorized by Dispatcher CC Call Control CMCE Circuit Mode Control Entity FE Functional Entity ISI Inter-System Interface LS Line Station MMI Man Machine Interface MS Mobile Station PDU Protocol Data Unit SAP Service Access Point SDL Specification and Description Language SNA Short Number Address SS Supplementary Service NOTE: The abbreviation SS is only used when referring to a specific supplementary service.

These functional entities can, for one call, be located in different TETRA systems, refer to EN 300 392-11-6 [3], clause 4. SIST EN 300 392-12-6 V1.3.1:2006

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; SIST EN 300 392-12-6 V1.3.1:2006

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 indication The authorized or dispatching user MS/LS (FE3 or FE7) shall offer an ACTIVATE indication to the user application to inform an activation of call authorization. Parameters for the primitive ACTIVATE indication shall be as defined in table 1. Table 1: Parameters for the primitive ACTIVATE indication Parameter Indication Activation result M Restricted user TETRA identity (ies) M (see note) NOTE: It is optional to support more than one identity.
