The test suites given in subclause 4.1 are based on the mapping of Functional Entities (FE) to Physical
Entities (PE) as shown in table 3.

different example physical scenarios.
The following figures illustrate mainly the SRF configurations. The SDP is included for better

AssistRequestInstructions
Cancel
PlayAnnouncement

SpecializedResourceReport
4.3.2 Main test groups
4.3.2.1 Capability tests (CA)
Capability testing provides a limited testing to ascertain the capabilities stated in the PICS can be
observed.
4.3.2.2 Valid Behaviour tests (BV)
Predefined state transitions are considered as valid. The test purposes in the valid behaviour test sub
group cover as far as reasonable the verification of the normal and exceptional procedures of the various
Finite State Machines (FSMs), i.e. a valid behaviour test is a test where the message sequence and the
message contents is considered as valid.
4.3.2.3 Invalid Behaviour tests (BI)
This test sub group is intended to verify that the IUT is able to react properly having received an invalid
Protocol Data Unit (PDU). An invalid PDU is defined as a syntactically incorrect message.
4.3.2.4 Inopportune Behaviour tests (BO)
This test group is intended to verify that the IUT is able to react properly in the case an inopportune
protocol event occurring. Such an event is syntactically correct but occurs when it is not expected, e.g. a
correctly coded operation is received in a wrong state (the IUT may respond by sending error
UnexpectedComponentSequence).
4.4 Test step structure
4.4.1 Preambles
The preamble test group contains the preamble test steps needed for initialization of the IUT before
testing the particular test purpose. Each preamble shall start from the IUT initial state as defined in
subclause 5.1.4.
4.4.2 Postambles
After each test case the IUT shall be brought back to the initial state as defined in subclause 5.1.4.

4.5 Timers of the Abstract Test Suite (ATS)
This subclause describes the timers and counters used in the ATS. The "min" and "max" indications
define if the timer value represents the minimum or maximum limit of a timer. The timer values contain
some additional tolerances for delays caused by test simulators. Therefore, a bigger timer tolerance is
given than defined in ETS 300 374-1 [1]:
Minimum value of ATS timer = minimum ETS timer;
Maximum value of ATS timer = maximum ETS timer × 1,2.
Table 4 shows the identified timers used in the ATS and the references to ETS 300 374-1 [1].

5 Test Purposes (TP)
5.1 Introduction
For each test requirement a TP is defined.
At the start of each test sub group the preambles and the postambles are listed.
5.1.1 Test purpose naming convention
The identifier of the TP is built according to the scheme in table 5.
