5 Test Purposes (TP)
5.1 Naming convention and strategy
5.1.0 Introduction
For each requirement in ETSI TS 124 229 [1] 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 5.1.1-1).
Table 5.1.1-1: TP identifier naming convention scheme
Identifier: IBCF__
= group 3 digit field representing group reference according to TSS
= TP number 3 digit sequential number (001-999)

5.1.2 Test strategy
As the base standard ETSI TS 124 229 [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 ETSI TS 101 553-1 [3]. The criteria applied include
the following:
 whether or not a test case can be built from the TP is not considered.
6 Test purposes IBCF test
