bearer-related transport mechanism: procedure tied to the procedures for basic call control and tied to a connection
in progress, active or in the clearing phase
NOTE: The call reference used by the basic call control procedure is adopted by the bearer-related service
invocations to correlate with the appropriate basic call control transaction.
bearer-independent transport mechanism: procedure independent of the procedures for basic call control and not
correlated to a connection
connection-oriented transport mechanism: mechanism requiring the establishment of a data link and a transport
association between the service requesting entity and the service provider
NOTE: It provides a facility to access common information element category operations where success and/or
failure reporting is required. It provides a call reference within the transport association as a means to
associate uniquely among the related transport messages.

6.1 Introduction
For each test requirement a TP is defined.
6.1.1 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 1).
Table 1: TP identifier naming convention scheme
Identifier: ___
= supplementary service: e.g. "GFP"
= type of IUT: U User
N Network
= clause 1 or 2 character field representing a clause number from
EN 300 196-1 [1]
= group 2 digit field representing group reference according to TSS
= sequential number (001-999)

6.1.2 Source of TP definition
The TPs are based on EN 300 196-1 [1].

 10 ETSI EN 300 196-3 V1.2.1 (2001-11)
6.1.3 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.

6.1.4 Test strategy
As the base standard EN 300 196-1 [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 300 196-2 [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.
6.1.5 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 clause 5.8.10 of EN 300 403-1 [6]. According to
these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message
indicating, in the third 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.
NOTE: Timer T322 is associated with that STATUS ENQUIRY/STATUS procedure.
