Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
The present document is part 2 of a multi-part deliverable covering the Subaddressing (SUB) service, as identified
below:
Part 1: "Protocol Implementation Conformance Statement (PICS)";
Part 2: "Test Suite Structure and Test Purposes (TSS&TP)".

1 Scope
The present document specifies the test suite structure and test purposes of the Subaddressing (SUB) service, based on
IP Multimedia Call Control Protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP)
Stage 3. Within the Next Generation Network (NGN) the stage 3 description is specified using the IP Multimedia
Communication 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. "SUB"
= 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 ES 283 003 [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 186 012-1 [2]. The criteria applied include the following:
• whether or not a test case can be built from the TP is not considered.
