22、 Notation WT Wireless Terminal 4 Abstract Test Method (ATM) This clause describes the ATM used to test the HIPERLAN 2 Data Link Control (DLC) Protocol - Extension for Home Environment at the AP side and at the MT side. 4.1 Test architecture RCP PCOPHYDLC/MACDLC/MACLower TesterPHYSUTARQRLC(IUT)RLC(AT
23、S)Notional UTFigure 1: Test architecture for DLC Extension for Home Environment A single-party testing concept is used, which consists of the following abstract testing functions: Lower Tester: A Lower Tester (LT) is located in the remote BRAN H/2 test system. It controls and observes the behaviour
24、of the IUT. RLC ATS: A RLC Abstract Test Suite (ATS) is located in the remote BRAN H/2 test system. RCP PCO: the Point of Control and Observation (PCO) for RLC testing is located at a SAP between the RLC layer and the MAC layer. All test events at the PCO are specified in terms of Abstract testing S
25、ervice Primitives (ATSP defined in clause 7) containing complete PDU. To avoid the complexity of data fragmentation and recombination testing, the SAP is defined below these functions. Notional UT: No explicit upper tester (UT) exists in the system under test. Nevertheless, some specific actions to
26、cover implicit send events and to obtain feedback information are necessary for the need of the test procedures. A black box covering these requirements is used in the SUT as a notional UT as defined in ISO 9646. This notional UT is part of the test system. ETSI ETSI TS 101 823-4-3 V1.3.1 (2004-08)
27、104.2 Test Configurations 4.2.1 Test Configurations for MT Four configurations are defined for MT testing. AP(T ester)MT(IU T )Figure 2: Normal configuration for MT The normal configuration is defined and used for functionality that requires only interaction between the tested MT and one AP. AP1MT(I
28、U T )AP2TesterFigure 3: Handover configuration for MT The handover configuration is used when the MT has to interact with two AP. In that case, the two simulated AP are configurable to be either a multi-sector AP or two separate AP. The concurrent TTCN facilities are used in this configuration. MT1M
29、T2(IU T )APTesterFigure 4: Direct mode configuration for MT The direct mode configuration is used for direct mode testing. The test system simulates one AP and one MT. The AP part of the test system is used to initialize the direct mode with the tested MT. The MT part of the system is used to verify
30、 the communication of the tested MT when the direct mode is active. The concurrent TTCN facilities are used in this configuration. ETSI ETSI TS 101 823-4-3 V1.3.1 (2004-08) 11WT2 WT1 Sender (IU T ) AP/CC T ester WT3 Figure 5: Direct mode Multicast with QoS configuration for MT The direct mode Multic
31、ast with QoS configuration is used for multicast connection with required QoS testing. The test system simulates one AP/CC and two WT. The AP/CC part of the test system is used to initialize the direct mode with the tested WTs. The WTs part of the test system is used to verify the communication of t
32、he tested MT when a multicast connection with QoS is active. The concurrent TTCN facilities are used in this configuration. 4.2.2 Test Configurations for AP Two configurations are defined for AP testing.

ETSI ETSI TS 101 823-4-3 V1.3.1 (2004-08) 125 Untestable Test Purposes (TP) This clause gives a list of TP, which are not implemented in the ATS due to the chosen ATM or oth
35、er restrictions. Table 1: Untestable TP Test purpose Reason 6 ATS conventions The ATS conventions are intended to give a better understanding of the ATS but they also describe the conventions made for the development of the ATS. These conventions shall be considered during any later maintenance or f
36、urther development of the ATS. The ATS conventions contain two clauses, the naming conventions and the implementation conventions. The naming conventions describe the structure of the naming of all ATS elements. The implementation conventions describe the functional structure of the ATS. To define t
37、he ATS, the guidelines of the document ETS 300 406 7 was considered. 6.1 Naming conventions 6.1.1 Declarations part This clause describes the naming conventions chosen for the elements of the ATS declarations part. 6.1.1.1 General The following general rules apply for the name giving in the declarat
38、ions part. All type definitions (simple type definitions, 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 type definition) shall be wr
39、itten in lowercase. Predefined types (e.g. BITSTRING8) are never used in structured type definitions, ASP type definitions or PDU type definitions. Simple types are used instead. 6.1.1.2 Test suite operations definition The test suite operation identifiers are composed of substrings in lowercase let
40、ters, except for standard prefix “TSO_“. An underscore character (“_“) separates each substring. EXAMPLE: TSO_substring 6.1.1.3 Test suite parameter declarations The test suite parameter identifiers are composed of substrings in lowercase letters, except for the standard prefix “TSP_“. An underscore
41、 character (“_“) separates each substring. EXAMPLE 1: TSP_t_wait If the test suite parameter references a Protocol Implementation Conformance Statement (PICS) item, the letter “C“ is added to the standard prefix. EXAMPLE 2: TSPC_encryption_support ETSI ETSI TS 101 823-4-3 V1.3.1 (2004-08) 13If the t
42、est suite parameter references a PIXIT item, the letter “X“ is added to the standard prefix. EXAMPLE 3: TSPX_pid 6.1.1.4 Test case selection expression definition The test case selection expression identifiers are composed of substrings in lowercase letters, beginning with the prefix “TCS_“. An unde
43、rscore character (“_“) separates each substring. 6.1.1.5 Test suite constant declarations The test suite constant identifiers are composed of substrings in lowercase letters, except for the prefix “TSC_“. An underscore character (“_“) separates each substring. If the test suite constant represents a
44、 system parameter, the complete name defined in the protocol standard is used. 6.1.1.6 Test suite variable declarations The test suite variable identifiers are composed of substrings in lowercase letters, except for the prefix “TSV_“. An underscore character (“_“) separates each substring. Complete
45、names as defined in the protocol standard are used. 6.1.1.7 Test case variable declarations The test case variable identifiers are composed of substrings in lowercase letters, except for the prefix “TCV_“. An underscore character (“_“) separates each substring. Complete names as defined in the proto
46、col standard are used. 6.1.1.8 Timer declarations Two types of timers can be identified: 1) Standardized: - Those defined in the protocol standard, e.g. T201. They use exactly the same name as in the standard. As there is a tolerance margin accepted for these timers, three values are needed: - The m
47、aximum value allowed, which will use the suffix “_max“; - The minimum value allowed, which will use the suffix “_min“; - The value actually implemented, with no suffix; EXAMPLE 1: T201_max, T201_min, and T201. 2) Not standardized: - Those not defined in the protocol standard, i.e. for execution use,
48、 e.g. a timer waiting for a response. These timers begin with the prefix “T_“, followed by a string in lowercase letters. EXAMPLE 2: T_resp represents a timer for controlling the response time of the IUT. 6.1.1.9 ASP type definitions The general conventions in clause 6.1.1.1 apply. The identifier of
49、 an ASP type uses the same name as the name defined in the protocol standard. ETSI ETSI TS 101 823-4-3 V1.3.1 (2004-08) 146.1.1.10 PDU type definitions The general conventions in clause 6.1.1.1 apply. The PDU type identifier shall identify the related structure or type as defined in the protocol standard. 6.1.1.11 CM type definitions The CM types are defined as the ASP types without sub-fields. 6.1.1.12 Alias definitions Alias definitions are not used. 6.1.2 Constraints part This clause describes the naming conventions chosen for
