17、ion x Figure 1: TSS for HIPERACCESS UNI SSCS The test suite is structured as a tree with a first level defined as UNI-AP or UNI-AT representing the protocol group “UNI SSCS part of CBCL for AP and UNI SSCS part of CBCL for AT“. 4.2 Test groups The test groups are organized in three levels. The first

18、 level creates one protocol group representing the protocol services. 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 UNI

19、 SSCS part procedures as defined in TS 102 115-2 2. 4.2.1.1 UNI SSCS procedures The UNI SSCS procedures group is divided in two functional modules. The first functional module identifies the convergence layer functions. The second functional module identifies the DLC connection functions. ETSI ETSI

21、ities 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 receipt or exchange of valid Protocol Data Units (PDUs). Valid PDUs means that

22、 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 syntactically invalid PDU. 4.2.2.4 Inopportune Behaviour (BO) tests Thi

23、s 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 conventions The TPs are defined following particular rules as shown in tabl
