ETSIETSI EN 300 497-2 V0.3.1 (1999-10)9A single-party testing concept is used, which consists of the following abstract testing functions:PCO:the Point of Control and Observation (PCO) for MAC Layer testing is located at the D-ServiceAccess Point (D-SAP) between the MAC layer and the Physical layer. All test events at the PCOare specified in terms of Physical Layer - Abstract Service Primitives (PHL-ASPs) (frame numberparameter added);CP_TC:Co-ordination Point Test Case (CP_TC) is located between the Main Test Component (MTC) andParallel Test Component (PTC) LT_TC in the test system. It is used for passing co-ordinationmessages between these two testing functions;CP_MAC:Co-ordination Point MAC (CP_MAC) is located between the MTC and PTC LT_MAC in the testsystem. It is equivalent to the PCO used for Data Link Control (DLC) layer testing in part 6 of thepresent document. All co-ordination messages at this CP are specified in terms of MAC-ASPs andDLC Protocol Data Units (DLC-PDUs);PTC LT_TC:the Lower Tester Parallel Test Component LT_TC (PTC LT_TC) is located in the test system. Itmakes restricted use of the PCO by only observing the test events in both directions. It assignspreliminary verdicts (the MTC assigns the final verdict);NOTE:This restricted use of the PCO is a non-ISO/IEC 9646-2 [14] application of the PCO.PTC LT_MAC:the Lower Tester Parallel Test Component LT_MAC (PTC LT_MAC) is located in the test system.It provides indirect control and observation of the Implementation Under Test (IUT) during testexecution, via the underlying service-provider. It does not assign any verdict;MTC:the Main Test Component (MTC) is located in the test system. It is responsible for creating andterminating the PTCs, managing the co-ordination points CP_TC and CP_MAC, and computationof the final test case verdict;Upper layers:no explicit Upper Tester (UT) exists in the test system. However, the System Under Test (SUT)(upper layers) needs to carry out some functions to achieve some effects of test co-ordinationprocedures.The primitives used at the PCO (physical SAP) are defined according to EN 300 175-2 [2] clause 7 and associatedsubclauses.The co-ordination messages used at CP_MAC co-ordination point are abstract primitives including protocol data unitsand frames. The abstract primitives (MAC ASPs) are defined according to EN 300 175-3 [3] clause 8 and associatedsubclauses. Two abstract primitives for starting and stopping the synchronization between the main test component andthe parallel test component LT_MAC are added for the needs of the tester. The protocol data units (DLC C-plane PDUs)are defined according to EN 300 175-4 [4] clause 7 and associated subclauses. The frames (DLC U-plane frames) aredefined according to EN 300 175-4 [4] clause 12 and associated subclauses.4.2Test strategyThe ATM defined in subclause 4.1 requires the use of concurrent TTCN, which is specified in Amendment 1 ofISO/IEC 9646-3 [15]. The parallel test components PTC_TC and PTC_MAC are, however, seen as two independententities. This means that there is no communication or synchronization between the two PTCs during the test.PTC_TC is specified in TTCN (see annex A). Since PTC_TC is only observing at the PCO, this ATS does not containany send statements. Once the Test Purposes (TP) are fulfilled, the PTC_TC terminates, i.e. there are no post ambles,unless required by the TP. No explicit co-ordination messages is exchanged at CP_TC. To simplify the TTCN test cases,the underlying service provider has been assigned the task of frame numbering. Consequently, a frame parameter hasbeen added to some of the PHL-ASPs.The requirements for PTC_MAC (see annex B) are specified using ETS 300 474 [9].SIST EN 300 497-2 V0.3.1:2003



ETSIETSI EN 300 497-2 V0.3.1 (1999-10)10The Main Test Component (MTC) creates the two PTCs (using CREATE operation), stimulates the PTC_MAC (usingMAC ASPs at CP_MAC) and then waits for the two PTCs to terminate (using the DONE event). The final verdict iscomputed as follows:-a PASS is assigned if PTC_TC returns a PASS verdict and the expected event is received from PTC_MAC atCP_MAC;-a FAIL verdict is assigned if PTC_TC returns a FAIL verdict independently of what is received from PTC_MACat CP_MAC;-an INCONC verdict is assigned if: PTC_TC returns an INCONC verdict and the expected event is received fromPTC_MAC at CP_MAC, or returns a PASS verdict and an unexpected event is received from PTC_MAC atCP_MAC.5Untestable Test Purposes (TP)This clause gives a list of TP which are not implemented in the ATS for PTC LT_TC (see annex A) due to the chosenATM or other restrictions.Table 1: Untestable TPTest purposeReasonTP/DB/BV-00It is not possible to distinguish, without confusion, if the PT is unlocked or crashed.TP/PG/BV-00No procedure can be defined to verify that the Fixed radio Termination (FT) manages correctlythe paging Extended Flag when it transmit pages.6ATS conventions (only applicable for PTC LT_TC)The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventionsmade for the development of the ATS. These conventions shall be considered during any later maintenance or furtherdevelopment of the ATS.The ATS conventions contain two clauses, the naming conventions and the implementation conventions. The namingconventions describe the structure of the naming of all ATS elements. The implementation conventions describe thefunctional structure of the ATS.To define the ATS, the guidelines of the documents ETS 300 406 [8] and ETR 141 [12] were considered.6.1Naming conventions6.1.1Declarations partThis subclause describes the naming conventions chosen for the elements of the ATS declarations part.6.1.1.1GeneralThe following general rules apply for the name giving in the declarations part. All type definitions (simple typedefinitions, structured type definitions, ASP type definitions and PDU type definitions) shall be written in uppercase.All element names (structured type definition), parameter names (ASP type definition) and field names (PDU typedefinition) shall be written in lowercase.Predefined types (e.g. BITSTRING [8]) are never used in structured type definitions, ASP type definitions or PDU typedefinitions. Simple types are used instead.SIST EN 300 497-2 V0.3.1:2003
