4.1 Configuration
The scope of the present document is to test the signalling and procedural aspects of the stage 3 requirements as
described in ETSI TS 124 610 [1]. The stage 3 description respects the requirements to several network entities and also
to requirements regarding to end 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:
Testing of the Network: This entity is responsible to perform the service. In case only the Gm interface is accessible
this shall be used instead. In this case, be aware that the verification of several requirements is impeded.

5 Test Purposes (TP)
5.1 Introduction
5.1.1 TP naming convention
Table 5-1: TP identifier naming convention scheme
Identifier: __
= supplementary service: e.g. "CH"
= type of IUT: U User
N Network
= 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 124 610 [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 186 007-1 [2].
5.2 User TPs for HOLD
5.2.0 Introduction
All PICS items referred to in this clause are as specified in ETSI TS 186 007-1 [2] unless indicated otherwise by
another numbered reference.
