1 Scope
The present document specifies the protocol and signalling conformance testing in TTCN-3 for the Mission Critical
services over LTE signalling and protocol requirements defined by 3GPP.
The following TTCN test specification and design considerations can be found in the present document:
- the test system architecture;
- the overall test suite structure;
- the test models and ASP definitions;
- the test methods and usage of communication ports definitions;
- the test configurations;
- the design principles and assumptions;
- TTCN styles and conventions;
- the partial Implementation eXtra Information for Testing (IXIT) proforma;
- the test suites.
The Abstract Test Suites designed in the document are based on the test cases specified in 3GPP TS 36.579-2 [3]. The
test cases specified in 3GPP TS 36.579-3 [4] are out of scope of the present document.
The applicability of the individual test cases is specified in the test ICS proforma specification in 3GPP TS 36.579-4
[5]). Where appropriate the Abstract Test Suites belonging to the present specification may refer to other Abstract Test
Suites e.g. 3GPP TS 36.523-3 [27] for test requirements related to the EPS (LTE) bearers which carry the Mission
Critical services data.
The present document is valid for TTCN development for Mission Critical services clients' conformance tests according
to 3GPP Releases starting from Release 13 up to the Release indicated on the cover page of the present document.

5 Test models
5.1 MCPTT over LTE
5.1.1 MCPTT Client on-network test model
The MCPTT Client on-network test model is depicted in figure 5.1.1-1. The test model consists of an IMS component
and an HTTP component, on top of the multi-testers test model (E-UTRA) specified in TS 34.229-3 [28]. These parallel
test components (PTCs) handle the IMS and HTTP signalling asynchronously.
The IMS PTC controls the IPCanEmu and the IP PTC. IPCanEmu is responsible for handling the E-UTRA cell(s)
configuration in the SS as well as the E-UTRA/EPC level signalling and related procedures. The IP PTC controls the IP
related configurations. IPCanEmu and IP PTC interface to the SS according to TS 36.523-3[27]. In addition, the IMS
PTC interfaces to the SS via a new port, SRTP, to support configuration of SRTP/SRTCP security in the SS and
transport of Floor Control messages, specified in TS 24.380 [10], from / to TTCN.
Figure 5.1.1-1: MCPTT Client on-network test model over LTE
5.1.2 MCPTT Client off-network test model
This test model is not supported by the present version of the specification.

3GPP TS 36.579-5 version 13.5.0 Release 13 11 ETSI TS 136 579-5 V13.5.0 (2020-04)
5.2 MCPTT over IP
5.2.1 MCPTT Client on-network test model
In order to facilitate testing of MCPTT signalling at the IMS and HTTP level and execute the test cases in an
environment without E-UTRA components and associated hardware, a test model over IP may be used as shown below
in Figure 5.2.1-1.
It consists of the same components, ports and ASPs as in the test model in subclause 5.1.1 except for the IPCanEmu
EUTRA component which is replaced by a dummy one. The ASPs defined for the system ports IP_SOCK,
IPsec_CTRL, IP_CTRL and SRTP are identical to those defined in subclause 5.1.1.
This test model may be considered RAT agnostic. It will setup the simulated MCPTT servers, configure the
corresponding UDP, TCP, IPsec, TLS and RTP/SRTP ports and run the IMS and HTTP signalling as required by the
test cases.
