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 supplementary service 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. "CCBS"
= type of IUT: U User
NNetwork
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)
5.1.2 Source of TP definition
The TPs are based on EN 300 359-1 [1].

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 and this is illustrated in table 2. This table should be
read in conjunction with any TP, i.e. use a TP as an example to fully understand the table.

NOTE: Text in italics will not appear in TPs and text between <> is filled in for each TP and may differ from one
TP to the next.
5.1.4 Test strategy
As the base standard EN 300 359-1 [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 300 359-2 [2]. The criteria applied include the
following:
- only the requirements from the point of view of the T or coincident S and T reference point are considered;
- whether or not a test case can be built from the TP is not considered.
5.2 Network TPs for CCBS
5.2.1 Network (S/T)
NOTE 1: All FACILITY messages in TPs associated with clause 9, use the dummy call reference as specified in
subclauses 8.3.2.2 and 8.3.2.4 of EN 300 196-1 [6] (bearer independent connectionless transport
mechanism). Unless stated otherwise, FACILITY messages are sent/received using point-to-point data
link (I frame) and the IUT is configured so that it "knows" that a point-to-point configuration exists at the
user's access.
NOTE 2: Although the sending or receiving of a message using the dummy call reference is independent of any
particular call state, in the following TPs call state N12 is used to show that the IUT has just begun
clearing of a call and call state N00 is used to indicate that Layer 2 is active and capable of carrying
bearer independent messages.
