24、ope The present document contains the Abstract Test Suite (ATS) to test the BRAN HIPERLAN Type 2; Data Link Control (DLC) protocol; Part 1: Basic data transport functions i. The objective of the present document is to provide a basis for conformance tests for HIPERLAN Type 2 equipment giving a high
25、probability of air interface inter-operability between different manufacturers HIPERLAN Type 2 equipmen t. The IS0 standard for the methodology of conformance testing (ISO/IEC 9646-1 3 and ISO/IEC 9646-2 4) as well as the ETSI rules for conformance testing (ETS 300 406 2) are used as a basis for the
26、 test methodology. Annex A provides the Tree and Tabular Combined Notation (TTCN) part of the ATS. Annex B provides the Partial Protocol Implementation Extra Information for Testing (PIXIT) Proforma of the MT side ATS. Annex C provides the Partial Protocol Implementation Extra Information for Testin
27、g (PIXIT) Proforma of the AP side ATS. Annex D provides the Protocol Conformance Test Report (PCTR) Proforma of the MT side ATS. Annex E provides the Protocol Conformance Test Report (PCTR) Proforma of the AP side ATS. 2 References The following documents contain provisions which, through reference

SUT DLC/MAC PHY Figure 1 : Test architecture for Error Control (RLC needed for association, etc.) A single-party te
40、sting concept is used, which consists of the following abstract testing functions: Lower Tester: ARQ ATS: ARQ PCO: RCP PCO: Notional UT: A Lower Tester (LT) is located in the remote BRAN W2 test system. It controls and observes the behaviour of the IUT. An ARQ Abstract Test Suite (ATS) is located in
41、 the remote BRAN W2 test system. The Point of Control and Observation (PCO) for ARQ testing is located at a SAP between the Error Control layer and the MAC layer. All test events at the PCO are specified in terms of Abstract Testing Service Primitives defined in Clause 7 and containing complete PDU.
42、 To avoid the complexity of data fragmentation and recombination testing, the SAP is defined below these functions. 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 Te
43、sting Service Primitives defined in Clause 7 and containing complete PDU. To avoid the complexity of data fragmentation and recombination testing, the SAP is defined below these functions. No explicit upper tester (UT) exists in the system under test. Nevertheless, some specific actions to cover imp
44、licit 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 IS0 9646 (3 to 7). This notional UT is part of the test system. ETSI 10 ETSI EN 301 823-1 -3 V1.l.l (2001-

46、PDU to or from MAC and Convergence Layers controlled by the Control Entity. Provide management of receive and transmit buffer. Provide traffic generation and absorption capabilities. Transmission: Handle the transmit window on a basis of sequence number; Evaluate ARQ feedback messages (integrity che

Reception: Handle the receive window including the knowledge of the buffer status; Generate ARQ feedback messages; Trigger the message handler to pass correct in-sequence PDU to t

In that case, the two simulated APs are configurable to be either a multi-sector AP or two separate APs. The concurrent TTCN facilities are used in this configuration.
