5 Test Purposes (TP)
5.1 Introduction
For each test requirement a TP is defined.
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 figure 1).
Identifier: __
= supplementary service: e.g. "CDIV"
= type of IUT: U User
N Network
yyy service
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)
Figure 1: TP identifier naming convention scheme
5.1.2 Test strategy
As the base standard TS 183 004 [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 TS 186 014-1 [10].
5.1.3 Configuration
For Application Server procedure testing, the ISC interface should be used. In case when the ISC interface is not
explicitly available it is also applicable to use any NNI interface such as the Mw, Mg or the Mx interface. The use of
the Gm interface is explicitly stated.
5.2 Signalling requirements
5.2.1 Actions at the diverting S-CSCF
TSS TP Reference Selection expression
Netw/DivertigS-CSCF CDIV_N01_001
Test purpose
The S-CSCF forwards the request to the AS based on the initial filter criteria roles indicating the UE B is
subscribed to CFU simulation service.

Ensure that the S-CSCF is able to forward a request to the AS based on the initial filter criteria for the CDIV service
if the called user is subscribed to the communication diversion service.
