1 Scope

This ETS contains the Abstract Test Suites (ATS) to test the Terrestrial Trunked Radio (TETRA) Direct

Mode Operation (DMO) Gateway V+D interface at layer 3, i.e. the GateWay Call Control (GWCC) and the

GateWay Mobility Management (GWMM) protocol. The GWCC and GWMM protocols are specified in

ETS 300 396-1 [1] and in ETS 300 396-5 [2]. The Test Suite Structure and Test Purposes (TSS&TPs) for

these ATSs are defined in ETS 300 394-4-8 [4].

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 [6], ISO/IEC 9646-2 [7],

ISO/IEC 9646-3 [8] and ISO/IEC 9646-5 [9], as well as the ETSI rules for conformance testing,

ETS 300 406 [5] and ETR 141 [10] are used as a basis for the test methodology.

Annex A provides the Tree and Tabular Combined Notation (TTCN) part of this ATS in an electronic file.

Annex B provides the partial Protocol Implementation eXtra Information for Testing (PIXIT) Proforma of

this ATS.

Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of this ATS.

4 Abstract Test Method (ATM)

This clause describes the ATM used for testing the GWCC and GWMM. The test method selected is the

embedded variant of the remote test method used in Single Party Testing (SPyT) context, as defined in

ISO/IEC 9646-2 [7], clause 11. This test method has been selected, because:

- it does not imply specific requirements to the Implementation Under Test (IUT);

- the upper Service Access Point (SAP) of the IUT cannot be directly observed;

- the variety of the possible TETRA implementations is a serious technical obstacle for the adoption

of a different ATM;

- this test method places minimum limitations in the realization of conformance testing.

4.1 Lower Tester (LT)

A LT is located in a remote TETRA test system. It controls and observes the behaviour of the IUT.

4.2 Upper Tester (UT)

There is no explicit UT in the remote test method, but the layers above inside the System Under Test

(SUT) are used implicitly for testing the GWMM and GWCC.
4.3 Test Co-ordination Procedures (TCP)

The implicit send events defined by the provider of an implementation in annex B serve the purpose of the

TCP. They are used as an input to the IUT communicating with the UT to initiate test events at the V+D

MLE layer.
4.4 Point of Control and Observation (PCO)

All test events at the PCO carrying service user data are specified in terms of GWCC and GWMM layer

PDUs. Only few Abstract Service Primitives (ASPs) are used for control or observation purposes.

4.5 Non-testable test purposes and implementation matters

The purpose of this ATS is to test the V+D interface of the gateway. The observable behaviour on the V+D

Air Interface (AI) in some cases is dependent on the behaviour on the DMO AI of the gateway. This

interface is not controlled by the test system, so it is assumed that the behaviour on the DMO AI is always

consistent with the requirement for this interface. However it also means that some of the test purposes

he following test purposes have been identified as being non-testable in the
become non-testable. T

selected test configuration, and therefore no abstract test cases are specified for the test purposes:

DMO_GATE_GWCC_CM_BV_TI_03 and DMO_GATE_GWCC_CM_BV_TI_06.

For test suite implementation, the upper layer may be realized as a MS-GW or as a simulation of its valid

behaviour, in order to test the dynamic behaviour of the gateway on the V+D AI.

5 ATS conventions

This clause describes the conventions applied to define the two ATSs and gives the naming conventions

chosen for the different elements of the ATSs.

The ATS conventions are intended to give a better understanding of the ATS but they describe also the

conventions made for the development of the ATS, thus for any later maintenance purposes or further

development of the ATS, the conventions described in this clause shall be considered.

5.1 Naming conventions
5.1.1 Declarations part

This subclause describes the naming conventions chosen for the elements of the ATS declarations part.

5.1.1.1 Test suite type and structured type definitions

The test suite type and test suite structured type identifiers describe the information elements, and each

whole word included in the name is written in lowercase starting by an uppercase letter:

EXAMPLE: Priority_Level_Type simple type;
SSI_Type simple type;
ITSI_Type structured type.

In the case an abbreviation is included in the declaration name, there is an underscore ("_") before and/or

after it, separating it from the rest of the identifier. This rule with abbreviations apply to all the naming

conventions in the whole test suite.
5.1.1.2 Test suite operations definitions

The test suite operation identifiers are composed of strings in uppercase letters starting by the uppercase

string "TSO_". The different strings in the definition are separated with underscores.

EXAMPLE: TSO_UPLANE_IS_TRANSMITTING.
5.1.1.3 Test suite parameter declarations

The test suite parameter identifiers are composed of strings in uppercase letters starting by the uppercase

string "PIC_" or "PIX_" and separated by underscores.
If the test suite parameter references a PICS item, the prefix "PIC_" is used.
EXAMPLE 1: PIC_CIRCUIT_MODE_CALL.
If the test suite parameter references a PIXIT item, the prefix "PIX_" is used.
EXAMPLE 2: PIX_DM_MS_ITSI.
Complete names as defined in the specifications are used.
5.1.1.4 Test case selection expression definitions

The naming conventions for the test case selection expression definitions use free text starting with an

uppercase letter. The name of the expression shall explain clearly the selection rule. The test case

selection expressions are generally logical combinations of the PICS element definitions.

SIST ETS 300 394-4-10 E1:2003
Page 12
ETS 300 394-4-10: June 1999
5.1.1.5 Test suite constant declarations

The test suite constant identifiers are composed of strings in uppercase letters starting by the uppercase

string "TSC_".
EXAMPLE: TSC_MS_VITSI.

Complete names as defined in the specifications are used. However, in the parameters including a dot

character, the dot is replaced by an underscore.
5.1.1.6 Test suite variable declarations

The test suite variable identifiers are composed of string in lowercase letters starting by the lowercase

string "tsv_".

If the test suite variable represents a system parameter or value, the name defined in the specifications is

used. However, in the variables including a dot character, the dot is replaced by an underscore.

5.1.1.7 Test case variable declarations

The test case variable identifiers are composed of strings in lowercase letters starting by the lowercase

string "tcv_".
EXAMPLE: tcv_result.
5.1.1.8 PCO declarations

The point of control and observation identifiers are composed of three to six capital letters, beginning with

an "L", as there are only LTs.
EXAMPLE: LGWCC Represents a PCO on GWCC module for PDUs.
5.1.1.9 Timer declarations
Two kinds of timers can be distinguished:
1) standardized:

Those defined in the standard, e.g. T303, use the same name as in the standard, beginning with

capital "T".
As there is a tolerance margin accepted for these timers, two values are needed:
- the minimum value allowed, which will use the suffix "_Min";
- the maximum value allowed, which will use the suffix "_Max".
EXAMPLE 1: T303_Min, T303_Max.
2) non-standardized:

Those not defined in the standard, i.e. for execution use, e.g. a timer waiting for a response. These

timers begin with the prefix "T_", followed by a string in lowercase letters with each word in the

following string starting with an uppercase letter.
EXAMPLE 2: T_IUT_Response;
T_NoResponse.
5.1.1.10 ASP type definitions

ASP definitions follow the specification in the ETS 300 396-5 [2] when a corresponding definition exists. If

not, a free name is used.

SIST ETS 300 394-4-10 E1:2003
Page 13
ETS 300 394-4-10: June 1999
5.1.1.11 PDU type definitions

The identifier of a PDU is given in a string in uppercase letters, which represents the layer message.

EXAMPLE: U_SETUP_Type for the U-SETUP layer 3 PDU;
D_DISCONNECT_Type for the D-DISCONNECT layer 3 PDU.
5.1.1.12 Alias definitions
No alias definitions are used in the test suite.
5.1.2 Constraints part

This subclause describes the naming conventions chosen for the elements of the ATS constraints part.

Constraint identifiers commence with uppercase. The remaining part of the name is separated from the

beginning with an underscore and is written in lowercase with each word starting with an uppercase letter.

Identifier names of elements concerning the same subject have equivalent names in the declaration and

the constraint part.
- Declaration part: D_CONNECT_Type;
- Constraint part: D_CONNECT_Direct.

The name of the modified constraint describes the particularity of the modified constraint:

EXAMPLE 1: - Declaration part: U_SETUP_Type;
- Constraint part: U_SETUP_GC_Direct.

If formal parameter lists are used, the variable names are written in lowercase. The variable name is the

same as the name of the element it is representing starting with prefix "cpa_".
EXAMPLE 2: cpa_location_update_type.

ETS 300 394-4-10: June 1999
5.1.3 Dynamic part

This subclause describes the naming conventions chosen for the elements of the ATS dynamic part.

5.1.3.1 Test case identifier

The identifier of a TC is built according to the test purpose name, as in table 1.

Table 1: TC naming convention

tt = Type of testing CA Capability Tests
BV Valid Behaviour Tests
BI Invalid Behaviour Tests
TI Timer expiry and counter mismatch tests
= test subgroup letters abbreviation of the subgroup name
(optional)
= sequential number 01-99 Test Purpose Number
5.1.3.2 Test step identifier

The test step identifier is built with a string of lowercase letters leaded by a string of capital letter and

joined by an underscore character. The first string indicates the main function of the test step; e.g. PRE

for preamble, PST for postamble, CS for check state steps, LTS for local tree name and STP for general

step. The second string indicates the meaning of the step.
EXAMPLES: PRE_Idle_To_Active;
PST_DisconnectCall;
CS_Check_Idle.
5.1.3.3 Default identifier
Two default identifiers are used, namely OtherwiseFail.
5.2 TC and TP naming
There is a single name for both the TC identifiers and the TP identifiers.
