1 Scope
This European Telecommunication Standard (ETS) specifies the stage 2 description of the
Supplementary Service Call Report (SS-CR) for the Terrestrial Trunked RAdio (TETRA).
SS-CR is a supplementary service which allows the call originator of an individual call to leave his/her
identity for the called party.
Man-Machine Interface and charging principles are outside the scope of this ETS.
Supplementary service specifications are produced in three stages according to the method defined in
CCITT Recommendation I.130 [1]. The stage 2 description identifies the functional capabilities and the
information flows needed to support the supplementary service as specified in its stage 1 description (see
ETS 300 392-10-2 [3]). The stage 2 description is followed by the stage 3 description, which specifies the
protocols at the air interface and at the various Inter-System Interfaces (ISI) to support the service.
This ETS is applicable to MS/LS and SwMIs involved in the operation of those supplementary services.
Specifications of inter-working gateways to non-TETRA networks (mainly PSTN and ISDN) while affected
by that ETS are outside the scope of this ETS.
Use of SDS-TL for call report is outside the scope of this ETS.
NOTE: The stage 2 description is followed by the stage 3 description, which specifies the
encoding rules for the information flows and process behavior for the different entities
in SwMI, MS and LS.
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references the
latest edition of the publication referred to applies.

telecommunication services supported by an ISDN and network capabilities of
an ISDN".

language (SDL) ".

3 Definitions, symbols and abbreviations
3.1 Definitions
For the purposes of this ETS, the following terms and definitions apply:
bearer service: type of telecommunication service that provides the capability for the transmission of
signals between user-network interfaces.
busy: property of a user for whom either a network determined user busy or a user determined user busy
condition applies (see ITU-T Recommendation I.221 [6]).
identity presentation: stored/displayed identification provided to the called party for subsequent call
back.
Mobile Station (MS): physical grouping that contains all of the mobile equipment that is used to obtain
TETRA services. By definition, a mobile station contains at least one Mobile Radio Stack (MRS).
CC-SS retention timer: timer started by the infrastructure upon disconnection of the call, which allows
the user to use the call Identification in order to invoke/activate/interrogate a supplementary service
related to that call. After expiry of the timer, the user is no longer able to use the call Identification in order
to carry out supplementary service procedures.
SS-CR message validity timer: timer controlled by the infrastructure but defined by the served user,
which determines how long a message can be stored in the infrastructure. After expiry of the timer the
message is deleted.
supplementary service: supplementary service modifies or supplements a bearer service or a
teleservice. A supplementary service cannot be offered to a customer as a stand alone service. It should
be offered in combination with a bearer service or a teleservice.
Switching and Management Infrastructure (SwMI): all of the TETRA equipment for a Voice plus Data
(V+D) network except for subscriber terminals. The SwMI enables subscriber terminals to communicate
with each other via the SwMI.
teleservice: type of telecommunications service that provides the complete capability, including terminal
equipment functions, for communication between users according to agreed protocols.
user A: specific user that originated the call and requested the supplementary service.
user B: user that was initially addressed in the original call set up.
user C: user who is the diverted-to user.
3.2 Symbols
There are no other symbols in this ETS besides those symbols used in SDL diagrams according to
ITU-T Recommendation Z.100 [2].

4 SS-CR Stage 2 Specifications
4.1 Functional model
4.1.1 Functional model description
The functional model shall comprise the following functional entities (FEs) for Individual Calls:
- FE1 Originating SS-CR Served user FE;
- FE21 Originating SS-CR Controlling FE;
- FE25 Terminating SS-CR Controlling FE;
- FE25`New Terminating SS-CR Controlling FE;
- FE5 Terminating SS-CR Affected user FE.
NOTE 1: FE25' exists only in case of call restoration.
NOTE 2: FE25' has the same functions as FE25; it acts as the Terminating SS-CR Controlling
FE in the case where FE5 has migrated to another location.
The following functional relationships shall exist between these FEs for Individual Calls:
- ra between FE1 and FE21;
- rb between either between FE21 and FE25 or FE21 and FE25';
- rc between FE25 and FE5.
Figure 1 shows these FEs and relationships.
