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 2 of a multi-part deliverable covering conformance test specification for Mission Critical

Services over LTE consisting of:

3GPP TS 36.579-1 [2]: "Mission Critical (MC) services over LTE; Part 1: Common test environment"

3GPP TS 36.579-2: "Mission Critical (MC) services over LTE; Part 2: Mission Critical Push To Talk

(MCPTT) User Equipment (UE) Protocol conformance specification" (the present document);

3GPP TS 36.579-3 [3]: " Mission Critical (MC) services over LTE; Part 3: Mission Critical Push To Talk

(MCPTT) Server Application conformance specification";

3GPP TS 36.579-4 [4]: "Mission Critical (MC) services over LTE; Part 4: Test Applicability and

Implementation Conformance Statement (ICS) proforma specification";

3GPP TS 36.579-2 version 14.9.1 Release 14 7 ETSI TS 136 579-2 V14.9.1 (2021-01)
1 Scope

The present document specifies the protocol conformance testing for testing a MCPTT Client for compliance to the

Mission Critical Push To Talk (MCPTT) over LTE 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 MCPTT 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 36.579-1 [2];

- Implementation Conformance Statement (ICS) TS 36.579-4 [4] and Implementation eXtra Information for

Testing (IXIT) TS 36.579-5 [5];
- the applicability of each test case TS 36.579-4 [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 EPS (LTE) bearers which carry the MCPTT data sent or received by the MCPTT

Client and which are required to be supported by the UE in which the MCPTT Client is installed. This is defined in

TS 36.523-1 [6].
