SIST EN 302 091-3 V1.1.1:2005 is the Slovenian adoption of an ETSI telecommunications standard for prenegotiation in Broadband Integrated Services Digital Network (B-ISDN) and Broadband Private Integrated Services Network (B-PISN). It specifies the Test Suite Structure and Test Purposes (TSS&TP) for DSS2, B-QSIG and SS7 implementations, so that conformance testing can be designed for user equipment claiming conformance to EN 302 091-1.

What does SIST EN 302 091-3 V1.1.1:2005 specify?

SIST EN 302 091-3 V1.1.1:2005 specifies the TSS&TP for prenegotiation on the QB, SB, TB and co-incident SB/TB reference points defined in ITU-T Recommendation I.413. It is the testing-oriented part of the prenegotiation series, and it feeds the later ATS and PIXIT proforma part.

The document is organized into scope, references, definitions and abbreviations, TSS, TP, compliance, and requirements for a comprehensive testing service. In practice, that structure shows where the test groups are defined, where the individual test purposes are described, and what a compliant abstract test suite has to follow.

What are the key requirements of SIST EN 302 091-3 V1.1.1:2005?

Clause 4 sets the Test Suite Structure (TSS) around signalling procedures at originating or terminating Call Control (CC) entities. The four groups are for an originating CC entity, a terminating CC entity, an originating or terminating CC entity acting as initiator, and an originating or terminating CC entity acting as responder. This matters because test selection depends on the role the implementation plays in the call.

Clause 5.1 requires each Test Purpose (TP) to be identified in a defined naming scheme and numbered from 01 within each group. The suite identifier uses the layer and the type of Implementation Under Test (IUT), with L3PR used for Layer 3 prenegotiation. This gives traceability between a requirement, the TP, and the implemented test case.

Clause 5.1.2 and 5.1.3 make the TP set depend on EN 302 091-1 and on the Protocol Implementation Conformance Statement (PICS) information from EN 302 091-2. The TPs are derived from analysis of the base protocol and the PICS, and they cover only externally observable behaviour and realistic situations. For testing teams, that means the cases are aimed at what equipment actually sends and receives, not internal design choices.

Clause 5.2 defines the main behaviour checks for the originating and terminating CC entities. The TP set checks when an IUT sends a preNegotiate invoke APDU together with call establishment, after the first end-to-end message, or after call establishment, depending on state. This is the core of the suite, because it verifies when prenegotiation may start in the call flow.

Clause 5.2 also checks how an initiator and a responder handle bearer proposals. The TP set covers bearerEstDirection, connectionCallRelation, modificationPossible, Alternative, and the acceptance or rejection of a proposal, including counterproposal and error return cases. In practice, these TPs show whether both sides encode and react to prenegotiation options in a compatible way.

Clause 6 gives the rules for a compliant Abstract Test Suite (ATS). A compliant ATS has to match the TPs, use an appropriate subset of the TSS, keep the same naming convention, preserve the link with the PICS proforma, and comply with ISO/IEC 9646-2. All testable TPs from clause 5 have to be included unless a chosen Abstract Test Method makes some of them untestable.

Clause 7 states that any organization claiming to provide a comprehensive testing service for user equipment claiming conformance to EN 302 091-1 shall use the Remote test method from ISO/IEC 9646-2 as a minimum. This is the practical rule for test labs and service providers.

What terms does SIST EN 302 091-3 V1.1.1:2005 define?

• Abstract Test Case - a test case defined in the OSI conformance testing framework, used to specify behaviour to be exercised against an IUT.
• Abstract Test Method (ATM) - the testing method defined by ISO/IEC 9646-1 that determines how the abstract tests are applied.
• Abstract Test Suite (ATS) - the complete set of abstract test cases used for conformance testing.
• Implementation Under Test (IUT) - the implementation being evaluated for conformance.
• Protocol Implementation Conformance Statement (PICS) - the statement of which options and capabilities an implementation supports.
• Protocol Implementation eXtra Information for Testing (PIXIT) - the extra implementation information needed to select and run tests.
• Test Purpose (TP) - a statement of the objective for one test, written so that a test case can be derived from it.

Who uses SIST EN 302 091-3 V1.1.1:2005?

This standard is used by protocol test developers, conformance laboratories, equipment vendors, and quality teams working on B-ISDN and B-PISN call control. It is also relevant to buyers and assessors who need to check whether an implementation can be tested against EN 302 091-1 in a structured way.

The main tasks are designing ATSs, selecting test cases from PICS information, and checking prenegotiation behaviour at the originating and terminating call control sides. It also supports organizations that provide remote conformance testing services.

Standard	What it contributes
ETSI EN 302 091-1	The prenegotiation protocol specification that the test purposes are based on.
ETSI EN 302 091-2	The PICS proformas used for test case selection.
ISO/IEC 9646-1	The conformance testing framework and the definitions used for ATS, IUT, TP and related terms.
ISO/IEC 9646-2	The abstract test suite specification and the testing methodology used for compliance.
ITU-T Recommendation I.413	The B-ISDN user-network interface reference points used in the scope.
ETSI ETS 300 406	The testing and specification methodology used when generating realistic conformance tests.
ETSI EN 302 091-4	The companion part that specifies the ATS and PIXIT proformas based on this part.

What does the SIST EN 302 091-3 V1.1.1:2005 document contain?

The document contains a TSS figure that groups tests by CC entity role, and a table that defines the TP identifier naming convention. It also contains a set of TP statements for originating, terminating, initiator and responder behaviour, written around APDU exchanges and call-state conditions.

Clause 6 gives the ATS compliance rules, and clause 7 states the minimum remote testing method for a comprehensive testing service. The bibliography points to supporting material on TTCN and the related call-control specification in a separated call and bearer control environment.
