The present document is part 2 of a multi-part deliverable covering the Anonymous Communication Rejection (ACR)
and Communication Barring (CB) simulation services, as identified below:

1 Scope
The present document specifies the test suite structure and test purposes of the Anonymous Communication Rejection
(ACR) and Communication Barring (CB) simulation service, based on stage three of the IMS simulation service
Anonymous Call Rejection (ACR), Incoming Communication Barring (ICB) and Outgoing Communication Barring
(OCB). 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. "ACR-CB"
= 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 183 011 [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 186 017-1 [i.1]. The criteria applied include the
following:
• whether or not a test case can be built from the TP is not considered.

Test purpose
ACR service rejects an anonymous communication, Privacy value is id.
Ensure that the ACR service rejects the incoming communication where the request includes the P-Asserted-Identity
header AND the Privacy header indicating “id”.
Ensure that the ACR is sending a 433 (Anonymity Disallowed) response when the communication is rejected.
Preconditions:
incoming-communication-barring active=true
conditions: sub element anonymous is evaluate to “true”
actions: sub element allow is evaluate to “false”

Test purpose
ACR service rejects an anonymous communication, Privacy value is id. An announcement is provided.
Ensure that the ACR service rejects the incoming communication where the request includes the P-Asserted-Identity
header AND the Privacy header indicating “id”.
Ensure that the ACR service provides an announcement to the originating user before sending a 433 (Anonymity
Disallowed) response when the communication is rejected.

Ensure that the communication is forwarded to voice message service instead of rejecting the communication with
a 433 (Anonymity Disallowed) final response.
