Page 9ETS 300 394-4-9: June 19991ScopeThis ETS contains the Abstract Test Suites (ATS) to test the TETRA Direct Mode Operation (DMO) MSGateway protocol at layer 3, called Direct Mode Call Control (DMCC) and the MS-Gateway protocol atlayer 2, the Medium Access Control (MAC) protocol. The DMCC and MAC protocols are specified inETS 300 396-1 [1]and in ETS 300 396-5 [2]. The Test Suite Structure (TSS) and Test Purposes (TPs) forthese ATSs are defined in ETS 300 394-4-7 [4].The objective of these test specifications are to provide a basis for approval tests for TETRA equipmentgiving a high probability of air interface inter-operability between different manufacturer's TETRAequipment.The ISO standard for the methodology of conformance testing, ISO/IEC 9646-1 [5], ISO/IEC 9646-2 [6],ISO/IEC 9646-3 [7] and ISO/IEC 9646-5 [8], as well as the ETSI rules for conformance testing,ETS 300 406 [9] and ETR 141 [10] are used as a basis for the test methodology.Annex A provides the Tree and Tabular Combined Notation (TTCN) part of these two ATSs.Annex B provides the Partial Protocol Implementation eXtra Information for Testing (PIXIT) Proforma ofthis ATS.Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of this ATS.2ReferencesThis ETS incorporates by dated and undated reference, provisions from other publications.

It is theembedded variant of the remote test method used in Single Party Testing (SPyT) context, as defined inISO/IEC 9646-2 [6], clause 11. This test method has been selected, because:-this test method implies no specific requirements from the Implementation Under Test (IUT);-the upper Service Access Point (SAP) of the IUT cannot be directly observed;-the variety of the possible TETRA implementations is a serious technical obstacle for the adoptionof a different ATM;-this test method places minimum limitations in the realization of conformance testing.SIST ETS 300 394-4-9 E1:2003

Page 13ETS 300 394-4-9: June 19994.2ATM for the layer 3 ATSThis subclause describes the different ATMs used for testing the Network Layer protocol. The selectedmethod is the remote method, as defined in ISO/IEC 9646-2 [6], clause 11.The remote test method has been selected, because:-this test method implies no specific requirements from the Implementation Under Test (IUT);-the upper Service Access Point (SAP) of the IUT cannot be directly observed;-the variety of the possible TETRA implementations is a serious technical obstacle for the adoptionof a different ATM;-this test method places minimum limitations in the realization of conformance testing.Since the protocol defines the operation of a MS-GW via gateway, only one interface is used. The protocolalso defines cases where the MS-GW is pre-empting an other DM-MS which is master of a call viaGateway; in these cases two interfaces need to be tested simultaneously. This implies that two testingmethods shall be used: the remote single-party test method (with one PCO) and the remote multi-partytest method with two PCOs.4.2.1Single PCO testingThe selected test method is illustrated in figure 2.Test systemSUTUpperlayersIUTNWK- PDUsTETRA physical layer and radio communicationUTPCOASPsNetworkDM-MAC layerDM-MAC layerTCP LT

Page 15ETS 300 394-4-9: June 19994.2.3 Test configurations and use of concurrent TTCNAs this ATS covers both single-party testing using non-concurrent TTCN, and multi-party testing usingconcurrent TTCN, the notation chosen for the complete ATS is concurrent TTCN syntax. Therefore, testscomponents are defined to describe the two configurations: the "single_party" configuration and the"multi_party" configuration, as shown in figures 4 and 5.The single_party configuration is used in case of single-party testing, i.e. for the protocol between theMS-GW and the gateway. Only one test component, which is the Main Test Component (MTC)MTC_SINGLE, connected to the IUT via the PCO LNWK, is needed is this case.MTC_SINGLEIUTLNWKFigure 4: Single_party configurationThe Multi_party configuration is used when an other DM-MS is needed to check the protocol, i.e. to testpre-emption when an other DM-MS is master. In this case, three components are needed, these are theMTC MTC_GATE_MS, and two parallel Test Components (PTCs) PTC_GATE and PTC_MS, which areconnected to the MTC via the two co-ordination points CP_GATE and CP_MS. PTC_GATE and PTC_MSare further connected to the IUT via the two PCOs LNWK and LNWK_MS.MTC_GATE_MSIUTLNWKCP_GATECP_MSPTC_GATEPTC_MSLNWK_MSFigure 5: Multi_party configurationSIST ETS 300 394-4-9 E1:2003



Page 16ETS 300 394-4-9: June 19995ATS conventionsThis clause describes the conventions applied to define the two ATSs and gives the naming conventionschosen for the different elements of the ATSs.The ATS conventions are intended to give a better understanding of the ATS but they describe also theconventions made for the development of the ATS, thus for any later maintenance purposes or furtherdevelopment of the ATS, the conventions described in this clause shall be considered.5.1Naming conventions5.1.1Declarations partThis subclause describes the naming conventions chosen for the elements of the ATS declarations part.5.1.1.1Test suite type and structured type definitionsThe test suite type and test suite structured type identifiers describe the information elements, and eachwhole word included in the name is written in lowercase starting by an uppercase letter:EXAMPLE:Priority_Level_Typesimple type;SSI_Typesimple type;ITSI_Typestructured type.In the case an abbreviation is included in the declaration name, there is an underscore ("_") before and/orafter it, separating it from the rest of the identifier. This rule with abbreviations apply to all the namingconventions in the whole test suite.5.1.1.2Test suite operations definitionsThe test suite operation identifiers are composed of strings in uppercase letters starting by the uppercasestring "TSO_". The different strings in the definition are separated with underscores.EXAMPLE:TSO_ACTIVE_IND_CALL_OCCUPATION_GATE_MS.5.1.1.3Test suite parameter declarationsThe test suite parameter identifiers are composed of strings in uppercase letters starting by the uppercasestring "PIC_" or "PIX_" and separated by underscores.If the test suite parameter references a PICS item, the prefix "PIC_" is used.EXAMPLE 1:PIC_CIRCUIT_MODE_CALL.If the test suite parameter references a PIXIT item, the prefix "PIX_" is used.E
