Foreword
This Technical Specification has been produced by the 3rd Generation Partnership Project (3GPP).
The contents of the present document are subject to continuing work within the TSG and may change following formal
TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.
y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,
updates, etc.
z the third digit is incremented when editorial only changes have been incorporated in the document.
The present document is part 1 of a multi-part deliverable covering conformance test specification for Mission Critical
Services consisting of:
3GPP TS 37.579-1 [2]: "Mission Critical (MC) services; Part 1: Common test environment" (the present
document)
3GPP TS 37.579-2 [24]: "Mission Critical (MC) services; Part 2: Mission Critical Push To Talk (MCPTT) User
Equipment (UE) Protocol conformance specification"
3GPP TS 37.579-4 [4]: "Mission Critical (MC) services; Part 4: Test Applicability and Implementation
Conformance Statement (ICS)"

Equipment (UE) Protocol conformance specification"
In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
ETSI
3GPP TS 37.579-7 version 17.5.0 Release 17 8 ETSI TS 137 579-7 V17.5.0 (2026-04)
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an agency
the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document
might not indicates a likelihood that something will not happen as a result of action taken by some agency
the behaviour of which is outside the scope of the present document
In addition:
is (or any other verb in the indicative mood) indicates a statement of fact
is not (or any other negative verb in the indicative mood) indicates a statement of fact
The constructions "is" and "is not" do not indicate requirements.

1 Scope
The present document specifies the protocol conformance testing for testing a MCData Client for compliance to the
Mission Critical Data (MCData) protocol requirements defined by 3GPP.
In particular the present document contains:
- the overall test structure;
- the test configurations;
- the conformance requirement and reference to the core specifications;
- the test purposes; and
- a brief description of the test procedure, the specific test requirements and short message exchange table.
The present document is valid for MCData Clients implemented according to 3GPP releases starting from Release 13
up to the Release indicated on the cover page of the present document.
The following information relevant to testing specified in the present document could be found in accompanying
specifications:
- default setting of the test parameters TS 37.579-1 [2];
- Implementation Conformance Statement (ICS) TS 37.579-4 [4] and Implementation eXtra Information for
Testing (IXIT) TS 37.579-5 [5];
- the applicability of each test case TS 37.579-4 [4].
The test cases are expected to be executed through the 3GPP radio interface. The present document does not specify the
protocol conformance testing for the 3GPP bearers which carry the MCData data sent or received by the MCData Client
and which are required to be supported by the UE in which the MCData Client is installed. This is defined in
TS 36.523-1 [6] for EPS (LTE) or TS 38.523-1 [45] for NR/5GC.
According to 3GPP drafting rules, the references clause shall list only documents that are explicitly mentioned in the
deliverable. This reference is not used within the document and thus shall be removed from references clause.
2 References
The following documents contain provisions which, through reference in this text, constitute provisions of the present
document.
- References are either specific (identified by date of publication, edition number, version number, etc.) or
non-specific.
- For a specific reference, subsequent revisions do not apply.
- For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including
a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same
Release as the present document.
