4.1 Introduction
Test purposes of the present document address the IMS functional entities that are accessible via the following
standardized DIAMETER interfaces: Ro and Rf.
NOTE: In a real operating network the different Diameter nodes would not connect directly to each other. The
connection is usually proxied through one or more Diameter Agents. In the following test architecture
figures the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for
conformance testing purposes.

5 Test Suite Structure (TSS) and Test Purposes (TP)
5.1 Test Suite Structure
5.1.1 TP naming convention
TPs are numbered, starting at 01, within each group. Groups are organized according to the TSS.
Table 1: TP identifier naming convention scheme
Identifier: ___
= Test Purpose: fixed to "TP"
Interface: RF or RO
= type of IUT: CDF, OCF or CTF
= group MS Message syntax
TC Type of Charging
EC Error Cases
CH Tariff Changes
RE Re-authorization
FH Failure Handling
FA Failover
CP Credit Pooling
OP Other procedures ([2], clause 6.5)
= sequential number (01 to 99)

5.1.2 Test strategy
As the base standards in ETSI TS 132 260 [1] and ETSI TS 132 299 [2] contain no explicit requirements for testing, the
TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 103 374-1 [4].
5.1.3 TP structure
Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs
more readable and checkable. A particular structure has been used which is illustrated in table 2. Table 2 should be read
in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehension of table 2.

TP to the next.
NOTE 2: All messages are considered as "valid and compatible" unless otherwise specified in the test purpose.
This includes the presence of all mandatory AVPs as specified in IETF RFC 3588 [8] and in
ETSI TS 132 299 [2], clauses 6.2.2, 6.2.3, 6.4.2 and 6.4.3.
NOTE 3: An AVP can be embedded into another AVP. This is expressed by indentations, e.g. if Message1 contains
AVP1 and AVP2 where AVP1 has AVP3 embedded this will be expressed like this:
sends/receives Message 1
 containing AVP1
  containing AVP3
  indicating .
 containing AVP2

5.2 Test Purposes
5.2.1 PICS references
All PICS items referred to in this clause are as specified in ETSI TS 103 374-1 [4] unless indicated otherwise by
another numbered reference. PICS items are only meant for test selection, therefore only PICS items with status
optional or conditional are explicitly mentioned.
