The tree is of rank 2 with the first rank a functional area and the second rank is the standard ISO conformance test categories. 4.2 Test groups 4.2.1 Introduction The test suite has a total of three levels. The first level is the root.
20、The second level separates the root into various functional areas. The third level is the standard ISO conformance test categories. 4.2.2 Root The root identifies the Decentralized Environmental Notification Basic Service (DEN) given in ETSI EN 302 637-3 1. 4.2.3 Groups This level contains height fu

25、n The description of the TP is built according to ETSI EG 202 798 i.1. ETSI EN 302 637-3 1 does not use the finite state machine concept. As consequence, the test purposes use a generic “Initial State“ that corresponds to a state where the IUT is ready for starting the test execution. Furthermore, t
26、he IUT shall be left in this “Initial State“, when the test is completed. Being in the “Initial State“ refers to the starting point of the initial device configuration. There are no pending actions, no instantiated buffers or variables, which could disturb the execution of a test. 5.1.4 Sources of T
27、P definitions All TPs have been specified according to ETSI EN 302 637-3 1. 5.1.5 Mnemonics for PICS reference To avoid an update of all TPs when the PICS document is changed, table 3 introduce mnemonics name and the correspondence with the real PICS item number. The PICS item column refers to table
28、s and items of ETSI TS 102 869-1 2. The PICS item as defined in ETSI TS 102 869-1 2 shall be used to determine the test applicability.
