6、1 1. The objective of this test specification is to provide a basis for conformance tests for BRAN HIPERACCESS equipment giving a high probability of air interface inter-operability between different manufacturers BRAN HIPERACCESS equipment. The ISO standard for the methodology of conformance testin
7、g (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 test methodology. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

17、ite is structured as a tree with a first level defined as PCL-AP or PCL-AT representing the protocol group “Common part PBCL for AP and Common part PBCL for AT“. 4.2 Test groups The test groups are organized in three levels. The first level creates one protocol group representing the protocol servic
18、es. The second level separates the protocol services in functional modules. The last level in each branch contains one or more of the standard ISO subgroups CA, BV, BI and BO. 4.2.1 Protocol groups The protocol groups identify the common part procedures as defined in TS 102 117-1 1.

19、 148-1-2 V1.2.1 (2004-04) 7 4.2.1.1 Common procedures The common part procedures group is divided in two functional modules. The first functional module identifies the procedures at the sender side. The last functional module identifies the procedures at the receiver side. 4.2.2 Main test groups The
20、 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 This test sub group shall provide limited testing of the major IUT capabilities aiming to insure that the claimed capabilities are cor
21、rectly 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 receipt or exchange of valid Protocol Data Units (PDUs). Valid PDUs means that the exchange of messages and the content of the exchanged m
22、essages 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 syntactically invalid PDU. 4.2.2.4 Inopportune Behaviour (BO) tests This test sub group shall verify that the IUT reacts in conform
23、ity 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 conventions The TPs are defined following particular rules as shown in table 1. Table 1: TP definition rules TP Id according to the TP
24、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 conventions defined in the subclause below. Reference The reference should contain the references of the subject to be validated by t
25、he 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 stimulus defines the test event to which the TP is related. Expected behaviour Definition of the events that are expected from
26、the IUT to conform to the base specification. ETSI ETSI TS 102 148-1-2 V1.2.1 (2004-04) 8 5.1.2 TP naming conventions The identifier of the TP is built according to table 2.
