Release 12 7 ETSI TS 101 595-2 V6.1.1 (2019-01)
4.1 Configuration
4.1.0 Introduction
The scope of the present document is to test the signalling and procedural aspects of the stage 3 requirements as
described in ETSI TS 124 616 [1]. The stage 3 description describes the requirements for several network entities and
also the requirements regarding for terminal devices. Therefore several interfaces (reference points) are addressed to
satisfy the test of the different entities.
Therefore to test the appropriate entities the configurations below are applicable.
4.1.1 Testing of the AS
The AS entity is responsible for performing and managing services. The ISC interface is the appropriate access point for
testing.

Figure 4.1.1-1: Applicable interface to test AS functionalities
If the ISC interface is not accessible it is also possible to perform the tests of the AS using any NNI (Mw, Mg, Mx)
interface (see figure 4.1.1-2). In case only the Gm interface is accessible this interface can be used instead for testing,
but the verification of all requirements may not be possible.

Figure 4.1.1-2: Applicable interfaces for tests using a (generic) NNI interface

Release 12 8 ETSI TS 101 595-2 V6.1.1 (2019-01)
4.1.2 Testing of the UE
There are special clauses in the protocol standard describing the procedures that apply at the originating and terminating
user equipment. Therefore the test configuration below has been chosen.

Figure 4.1.2-1: Applicable configuration to test UE functionalities
5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP naming convention
TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references
are added to identify the actual test suite and whether it applies to the network or the user (see table 5.1.1-1).
Table 5.1.1-1: TP identifier naming convention scheme
Identifier: __
= supplementary service: e.g. "MCID"
= type of IUT: U User equipment
N Network entity
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)

5.1.2 Test strategy
As the base standard ETSI TS 124 616 [1] contains no explicit requirements for testing, the TPs were generated as a
result of an analysis of the base standard and the PICS specification ETSI TS 101 595-1 [2]. The criteria applied include
the following:
• whether or not a test case can be built from the TP is not considered.
