1 Scope
The present document specifies the test suite structure and test purposes of the Closed User Group (CUG) service, based
on stage three of the IMS closed user group (CUG) simulation services. Within the Next Generation Network (NGN)
the stage 3 description is specified using the IP-Multimedia Call Control Protocol based on Session Initiation Protocol
(SIP) and Session Description Protocol (SDP).

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 table 1).
Table 1: TP identifier naming convention scheme
Identifier: __
= supplementary service: e.g. "CUG"
= type of IUT: U User – equipment
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 TS 183 054 [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 186 016-1 [2]. The criteria applied include the following:
• Whether or not a test case can be built from the TP is not considered.
