The Test Suite Structure is in close alignment with TS 129 235 [1] and TS 129 163 [2].

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).

As the base standard TS 129 235 [1] and TS 129 163 [2] 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 101 572-1 [6]. The criteria
