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 01, within each group. Groups are organized according to the TSS. Additional references
are added to identify the actual test suite (see table 1).
Table 1: TP identifier naming convention scheme
Identifier: __
= layer + type of IUT: "L3BN" for Layer 3Basic call/bearer control,
IUT = Network
= group number: two character field representing the group reference
according to TSS
= sequential number: (01-99)
5.1.2 Source of TP definition
The TPs are based on EN 300 443-1 [1].
5.1.3 Test strategy
As the base standard EN 300 443-1 [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 EN 300 443-2 [2].
The TPs are only based on conformance requirements related to the externally observable behaviour of the IUT, and are
limited to conceivable situations to which a real implementation is likely to be faced (ETS 300 406 [6]).
5.1.4 Test of call states
Many TPs include a reference to the IUT's final call state after the realization of the TP. In these cases the TP includes
the requirement to ensure that the IUT has entered this particular final call state. Ensuring that the IUT is in a particular
call state shall be realized by following the procedures described in subclause 5.6.11 of EN 300 443-1 [1]. According to
these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message
indicating, in the fifth octet of the Call state information element, the current call state of the IUT. This exchange of
messages is not mentioned explicitly in each TP but is considered to be implicit in the reference to the final call state.
This way of phrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and to improve
the readability.

All PICS items referred to in this subclause are as specified in EN 300 443-2 [2] unless indicated otherwise by another
numbered reference.
Unless specified:
- the messages indicated are valid and contain at least the mandatory information elements and possibly optional
information elements;
