1 Scope
This ETS contains the test specifications: Test Suite Structure and Test Purposes (TSS&TPs) and the
Abstract Test Suites (ATSs) to test conformity of products to the TETRA Direct Mode Operation (DMO)
protocols. This ETS is divided into several parts, each one dealing with one TSS&TP or one ATS for the
test of a layer 2 or layer 3 protocol for DMO.
This present sub-part 7 deals with TSS&TP for a Mobile Station (MS) connected to a Gateway (MS-GW).
NOTE: Sub-part 8 deals with TSS&TP for the other part of the DMO Gateway, which is a
GateWay (GW) connecting the MS-GW to the Switching and Management
Infrastructure (SwMI) of a Voice plus Data (V+D) system.
Testing of security features is outside the scope of this ETS.
The objective of this test specification is to provide a basis for approval tests for TETRA equipment giving
a high probability of air interface inter-operability between different manufacturer's TETRA equipment.
The ISO standard for the methodology of conformance testing, ISO/IEC 9646-1 [5] and
ISO/IEC 9646-2 [6], as well as the ETSI methodology for conformance testing, ETS 300 406 [7], are used
as the basis for the test methodology.

normative references are cited at the appropriate places in the text and the publications are listed

4.1 NWK layer or Layer 3 test groups
The first level separates the NWK layer (or layer 3) in different protocols (Circuit mode, Short Data
Service). Next level splits protocol testing into functional test groups according to the type of testing:
Capability test (CA), Valid Behaviour (BV) and Timer tests (TI). Further level classifies the possible
operations in each protocol condition or state.
The following list defines the NWK layer test group names and identifiers used for those:
MS connected to a gateway GW (DMO_MSGW_NWK):
Direct Mode Call Control (DMCC):
Circuit mode (CM):
Capability tests (CA);
Valid Behaviour tests (BV):
from Idle state(ID);
from Idle state, channel busy (IB);
from TX occupation State (TXO);
from RX occupation State (RO);
from TX Reservation (TR);
from RX Reservation State (RR).
Timer Tests (TI).
Short Data Service (SDS):
Capability tests (CA);
Valid Behaviour tests (BV):
from Idle state(ID);
from Idle state, channel busy (IB);
from RX Occupation State (RO);
from TX Reservation State (TR);
from RX Reservation State (RR).
Timer Tests (TI).
Direct Mode Mobility Management (DMMM).
4.2 Layer 2 test groups
The first level of the Layer 2 test groups separates the test suite in functional test groups: CA, BV and TI.
The second level of the test subgroups is used to form a division of protocol requirements.
In the case of an MS connected to a gateway, layer 2 contains the MAC only and is structured as follows:
MS connected to a gateway MAC layer (DMO_DMO_MSGW_MAC):
Capability tests (CA);
Valid behaviour tests (BV):
Channel usage (CU);
Signalling messages (SM);
Traffic mode (TM).
Timer tests (TI).
4.3 Test group description
Capability (CA) tests provide limited testing that the observable capabilities of the IUT are in accordance
with the conformance requirements and the additional capabilities claimed in the PICS/PIXIT.
The Valid Behaviour (BV) group tests an IUT in response to valid behaviour of the test system. "Valid"
means that a test event is syntactically and contextually correct. All test cases in the valid behaviour group
are intended to verify as thoroughly as possible the various functions of the protocol.
Different timers are defined to supervise the various state transitions. The Timer (TI) test group is
intended to verify that the IUT is reacting properly to an expiry of one of the timers or to a counter
mismatch.

5 Introduction to Test Purposes (TPs)
The test purposes for each test suite are defined in clause 6 of this ETS for NWK layer and MAC layer.
5.1 Test purpose definition conventions
5.1.1 Text and MSCs
Each TP is described in a table that contains the following information:
Table 0
TP-Name Reference: reference to the paragraph number of
The TP name is a unique identifier, specification ETS 300 396-5 [2] stating this conformance

below. (it is also the name of the
corresponding test case)
Purpose purpose of the test itself, indicating for example the test performed against a
requirement of the protocol, described by this test purpose.
Example: test of changeover initiated from RX reservation state.
Test description body of the test
Pass criteria visible action to be observed at PCO to declare that the IUT passes the test and
conforms to the specifications
Selection expression based on ETS 300 396-8-3 [3] PICS statements, used to select or
deselect the corresponding test case according to the options of the
implementation.
Preamble "None" or name of the preamble procedure bringing the IUT from idle state to
the state required to run the test.
For example: idle_to_RX_reservation.
"None" or name of the postamble to bring the IUT back to idle state,
Postamble
for example: RX_occupation_to_idle.
The preambles and postambles are described using MSCs and are shown in the following paragraphs.
5.1.2 Preamble descriptions
Preambles are used to bring the IUT from the idle state to the state where the test takes place. As the
protocol has different options, as for instance the use of presence check or the absence of presence
check, there are several ways to reach a given state. The preamble has to be chosen according to the IUT
capabilities and the implemented options.
