SIST ETS 300 392-10-2 E2:2003 is the Slovenian adoption of ETS 300 392-10-2 for Terrestrial Trunked Radio (TETRA) Voice plus Data (V+D), Part 10, Sub-part 2. It specifies the Stage 1 service description of Call Report (CR): how the service behaves when a called user is busy, does not answer, or is not reachable, and how the identity presentation information is handled for the called party.

What does SIST ETS 300 392-10-2 E2:2003 specify?

SIST ETS 300 392-10-2 E2:2003 specifies the Stage 1 requirements for the Call Report (CR) supplementary service in TETRA. Stage 1 is the user-level service description, so the document focuses on what the service should do in operation, not on the detailed protocol or human-machine interface.

The standard covers service procedures, successful and unsuccessful outcomes, interactions with other TETRA supplementary services, and inter-working considerations. It also states that charging principles and Man Machine Interface are outside its scope, and that use of SDS-TL to provide Call Report is outside its scope.

The document is organized into Scope, Normative references, Definitions, symbols and abbreviations, the SS-CR Stage 1 specification, inter-working considerations, and an overall SDL description.

What are the key requirements of SIST ETS 300 392-10-2 E2:2003?

Service behavior and applicability

SIST ETS 300 392-10-2 E2:2003 defines Call Report as a supplementary service that lets calling user A leave identity presentation information for called user B after a failed call. In practice, this means the service is meant to support callback-type situations after busy, no reply, or not reachable outcomes.

The service applies to TETRA individual data and speech teleservices and to TETRA individual circuit mode bearer services, including data services. It does not apply to group calls or to SDS short data system, so implementers should not plan CR for those cases.

Provisioning and subscription

SIST ETS 300 392-10-2 E2:2003 allows CR to be made available either to subscribed users or to all users in a system. User B cannot block the presentation of CR information, and the identity presentation contains the subscriber’s Individual TETRA Subscriber Identity (ITSI).

The only subscription options listed are priority of the reported call and time information for the CR invocation. This matters because operators and vendors must decide what subscription data they support in the SwMI.

Invocation, timers, and cancellation

SIST ETS 300 392-10-2 E2:2003 distinguishes between busy, no reply, and not reachable cases. For busy and no reply cases, user A may request CR around call disconnection, while the SwMI retains call information for a period governed by the CC-SS retention timer.

For not reachable calls, the SwMI monitors user B until reachability changes and uses the SS-CR message validity timer to control how long the message is kept. The served user defines that timer value at invocation, so system behavior depends on user-defined timing and infrastructure handling.

Rejection and exceptional handling

SIST ETS 300 392-10-2 E2:2003 requires the SwMI to reject CR requests when user A is not permitted or when the service cannot be applied. Examples given include withdrawal, no subscription, completion failure, request limits, unsupported inter-working, and expiry of the CC-SS retention timer.

The standard also rejects invocation when user A is already connected in a call. In practice, this tells implementers when the service must fail cleanly rather than proceed.

Interactions with other services

SIST ETS 300 392-10-2 E2:2003 says CR has no interaction with most listed supplementary services, including calling line identification presentation, call waiting, call hold, access priority, priority call, and others. It gives specific rules for forwarding cases such as CFU, CFB, CFNRy, and CFNRc.

That matters because forwarding can change whether CR applies to user B or diverted-to user C, and area selection and BIC can prevent call setup and therefore prevent CR invocation.

Inter-working

SIST ETS 300 392-10-2 E2:2003 limits CR availability across networks to the capabilities of both networks and the inter-working functions between them. For multi-network deployments, that means CR support depends on both sides of the connection.

What terms does SIST ETS 300 392-10-2 E2:2003 define?

• Call Report (CR) - A supplementary service that sends identity presentation information after a failed call to busy, no reply, or not reachable user B.
• Mobile Station (MS) - The mobile equipment grouping used to obtain TETRA services, containing at least one Mobile Radio Stack (MRS).
• Switching and Management Infrastructure (SwMI) - The TETRA network equipment that lets subscriber terminals communicate with each other.
• TETRA subscriber identity - The document uses ITSI for Individual TETRA Subscriber Identity and GTSI for Group TETRA Subscriber Identity.
• CC-SS retention timer - The timer that keeps call information available after disconnection so CR can still be requested.
• SS-CR message validity timer - The timer that controls how long the CR message remains stored before it is deleted.
• Busy - Either network determined user busy (NDUB) or user determined user busy (UDUB).
• Supplementary service - A service that modifies or supplements a bearer service or teleservice and is not offered on its own.

Who uses SIST ETS 300 392-10-2 E2:2003?

SIST ETS 300 392-10-2 E2:2003 is used by TETRA network operators, SwMI vendors, system integrators, and test engineers who need to define or verify CR behavior. It is also relevant to buyers and technical specifiers who want to know how a network handles identity presentation after failed calls.

The standard is especially useful when planning service provisioning, inter-working between networks, and validation of supplementary service behavior in Voice plus Data TETRA systems.

What changed in SIST ETS 300 392-10-2 E2:2003 from the previous edition?

SIST ETS 300 392-10-2 E2:2003 is identified as the second edition of ETS 300 392-10-2. The document history lists a first edition in April 1996 and a second edition in August 2000.

Which standards are used with SIST ETS 300 392-10-2 E2:2003?

Standard	What it contributes
CCITT Recommendation I.130	Method for characterizing telecommunication services.
ITU-T Recommendation I.221	Common specific characteristics of services.
ITU-T Recommendation Z.100	Specification and Description Language (SDL) used for the overall process model.
ETS 300 392-2	TETRA Voice plus Data Air Interface, including the referenced CC-SS retention timer context.

The foreword also places this ETS within the 14-part TETRA V+D series, alongside parts for general network design, interworking, gateways, security, network management services, supplementary services stages 2 and 3, the SDL model, and the PICS proforma.

What does the SIST ETS 300 392-10-2 E2:2003 document contain?

SIST ETS 300 392-10-2 E2:2003 contains a formal Stage 1 service description, the applicable definitions and abbreviations, and a structured procedure section for normal and exceptional operation. It also includes a long interaction list showing how CR behaves with other supplementary services.

The document includes a table of subscription parameters and an overall SDL diagram for the CR process. Those elements are used for service design, implementation, and conformance checking.

1 Scope
This European Telecommunication Standard (ETS) defines the Stage 1 specifications of the Call Report
(CR) supplementary service for the Terrestrial Trunked RAdio as provided by European operators.
Stage 1 is an overall service description from the users point of view but does not deal with the details of
the human interface itself.
This ETS specifies the service description of the supplementary service and the procedures to be
expected with successful and unsuccessful outcomes. In addition the ETS specifies the interactions with
other TETRA supplementary services and inter-working considerations.
Supplementary service specifications are produced in three stages according to the method defined in
CCITT Recommendation I.130 [1]. The Stage 1 description given in this ETS gives the supplementary
service requirements seen from the user point of view. 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. 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.
Charging principles and Man Machine Interface are outside the scope of this ETS.
The CR supplementary service enables the call originator to leave his/her identity for the called party.
Use of SDS-TL to provide Call Report is outside the scope of this ETS.
