6、 Suite Structure (TSS) and Test Purposes (TP) to test the BRAN HIPERACCESS; Packet based Convergence Layer; Part 2: Ethernet Service Specific Convergence Sublayer (SSCS). The objective of the present document is to provide a basis for conformance tests for BRAN HIPERACCESS equipment giving a high pr
7、obability of air interface inter-operability between different manufacturers BRAN HIPERACCESS equipment. The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 4 and ISO/IEC 9646-2 5) as well as the ETSI rules for conformance testing (ETS 300 406 3) are used as a basis for the t
8、est methodology. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

17、for the conformance testing. Test Suite Protocol group Protocol subgroup Test group CA BV BI BO ESS-AP/ ESS-AT Ethernet SSCS procedures RFC 2684 x Figure 1: TSS for HIPERACCESS Ethernet SSCS The test suite is structured as a tree with a first level defined as ESS-AP or ESS-AT representing the protoc
18、ol group “Ethernet SSCS for AP and Ethernet SSCS for AT“. 4.2 Test groups The test groups are organized in three levels. The first level creates one protocol group representing the protocol services. The second level separates the protocol services in functional modules. The last level in each branc
19、h contains one or more of the standard ISO subgroups CA, BV, BI and BO. 4.2.1 Protocol groups The protocol groups identify the Ethernet Service Specific PBCL procedures as defined in TS 102 117-2 2. 4.2.1.1 Ethernet SSCS procedures The Ethernet SSCS procedures group is divided in one functional modu
20、le. The functional module identifies the RFC 2684 procedures. ETSI ETSI TS 102 148-2-2 V1.2.1 (2004-04) 7 4.2.2 Main test groups The main test groups are the capability group, the valid behaviour group, the invalid behaviour group and the inopportune behaviour group. 4.2.2.1 Capability (CA) tests Th
21、is test sub group shall provide limited testing of the major IUT capabilities aiming to insure that the claimed capabilities are correctly supported, according to the PICS. 4.2.2.2 Valid Behaviour (BV) tests This test sub group shall verify that the IUT reacts in conformity with the TS, after receip
22、t or exchange of valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged messages are considered as valid. 4.2.2.3 Invalid Behaviour (BI) tests This test sub group shall verify that the IUT reacts in conformity with the TS, after receipt of a
23、 syntactically invalid PDU. 4.2.2.4 Inopportune Behaviour (BO) tests This test sub group shall verify that the IUT reacts in conformity with the TS, after receipt of a syntactically correct PDU not expected in the actual message exchange. 5 Test Purposes (TP) 5.1 Introduction 5.1.1 TP definition con
24、ventions The TPs are defined following particular rules as shown in table 1. Table 1: TP definition rules TP Id according to the TP naming conventions Reference. Initial condition. Stimulus. Expected behaviour. TP Id The TP Id is a unique identifier it shall be specified according to the TP naming c
25、onventions defined in clause 5.1.2. Reference The reference should contain the references of the subject to be validated by the actual TP (specification reference, clause, and paragraph). Condition The condition defines in which initial state the IUT has to be to apply the actual TP. Stimulus The st
26、imulus defines the test event to which the TP is related. Expected behaviour Definition of the events that are expected from the IUT to conform to the base specification.
