4.1 Configuration
The scope of the current specification is to test the signalling and procedural aspects of the stage 3 requirements as
described in TS 183 008 [3]. 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 2: Applicable interface to test AS functionalities
If the ISC interface is not accessible it is also possible to perform the test of the AS using any NNI (Mw, Mg, Mx)
interface (see figure 3). 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.

4.1.3 Testing of the IBCF
The IBCF is the separation point between trusted and entrusted IMS networks and can be tested with the test
configuration in figure 5.

If the ISC interface is not accessible it is also possible to perform the test of the AS using any NNI (Mw, Mg, Mx)
interface (see figure 3). 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.

5 Test Purposes (TP)
5.1 Introduction
For each test requirement a TP is defined.
All PICS items referred to in this clause are as specified in TS 186 005-1 [8] unless indicated otherwise by another
numbered reference.
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 1).
Table 1: TP identifier naming convention scheme
Identifier: __
= supplementary service: e.g. "TIP"
= type of IUT: U User
N Network entity, e.g. P-CSCF
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)

TSS TP TIP/TIR reference Selection expression
User/TermUserE TIP_U01_001 4.5.2.12 PICS 2/6, 1/2
Test purpose:
The Terminating UE supports the "from-change" tag in the Supported header.
Ensure that the Terminating UE supports the "from-change" tag in the Supported header. If the UE receives a
"from-change" tag in a Supported header in an initial INVITE, the UE sends the "from-change" tag in the Supported
header in any provisional or final response message (e.g. 180, 183, 200).
SIP messages: INVITE: Supported: from-change
   18x/200: Supported: from-change
Comments:

Test purpose:
The Terminating UE sends an UPDATE request with an updated From and To header.
Ensure that the Terminating UE supports the "from-change" tag in the Supported header. If the UE receives a "from-
change" tag in a Supported header in an initial INVITE, the user equipment sends an UPDATE request after the ACK
for the 200 OK INVITE was received containing a connected identity in the From header.
SIP messages: INVITE: Supported: from-change

Ensure that the Terminating UE having subscribed to TIR temporary mode, default value "presentation not restricted",
to override the default TIR setting, sends a Privacy header with value "id" in any non 100 response message (e.g. 180,
183, 200).

The Terminating UE overrides a default "Presentation restricted" by sending Privacy "none".
Ensure that the Terminating UE having subscribed to TIR temporary mode, default value "presentation restricted", to
override the default TIR setting, sends a Privacy header with value "none" in any non 100 response message (e.g. 180,
183, 200).
