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: __
= service + type of IUT: "MODN" for modification, 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 301 003-1 [3].
5.1.3 Test strategy
As the base standard EN 301 003-1 [3] 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 301 003-2 [4].
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 [1]).
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 [2]. 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.
5.2 TPs for the Peak cell rate modification, network
All PICS items referred to in this subclause are as specified in EN 301 003-2 [4] unless indicated otherwise by another
numbered reference.

information element,
- sends no message and enters N10.

type information element,
- sends no message and enters N10.
MODN_01_05
Ensure that the IUT in N10, having received a MODIFY ACKNOWLEDGE message, including a broadband report
type information element requesting confirmation, to indicate that the modification of the connection has been
confirmed by the remote user,
- sends a CONNECTION AVAILABLE message and remains in N10.
MODN_01_06
Ensure that the IUT in N13, on receipt of a MODIFY REJECT message,
- sends no message and enters N10.
MODN_01_07
Ensure that the IUT in N13, on receipt of a STATUS message (call state: 10, cause value: 97 or 101) with diagnostic
identifying of the MODIFY REQUEST message,
- sends no message and enters N10.
MODN_01_08
Ensure that the IUT in N13, on receipt of a STATUS message (call state: 10, cause value: 97 or 101) without diagnostic
identifying of the MODIFY REQUEST message,
