Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Mobile Standards Group (MSG).
The present document is a single-part deliverable covering the "Abstract Test Suite (ATS) and Protocol Implementation
eXtra Information for Testing (PIXIT)".
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of

1 Scope
The present document contains the Abstract Test Suite (ATS) for eCall (Higher Layer Application Protocols) HLAP for
the test purposes (TPs) as defined in CEN EN 16454 [i.1] in compliance with the relevant requirements and in
accordance with the relevant guidance given in ISO/IEC 9646-7 [i.11].
The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [i.8] and ISO/IEC 9646-2 [i.9]) as well
as the ETSI rules for conformance testing (ETSI ETS 300 406 [i.12]) are used as a basis for the test methodology.
The TPs defined in CEN EN 16454 [i.1] are implemented by different ATSs. The eCall HLAP ATS is defined in the
present document. The relevant eCall tests related to GSM and UMTS technologies are identified in
ETSI TS 102 936-1 [i.4] and ETSI TS 102 936-2 [i.5].
The eCall HLAP ATS of this present document contains only tests which do not require the MNO test point and hence
the ATS implements only a subset of all available TPs. The detailed ATS coverage is defined in clause 5.
The support of optional features is defined by the Protocol Implementation Conformance Statement (PICS) in clause 7.

The UIPort handles the interaction with the operator by providing a means to display information about required
operator actions as well as a way of capturing input from the operator.

The LogMessagePort is intended for debugging information from the adaptation. Debug messages are processed by the
log component to separate them from the main body of the test case and also to provide an efficient means of filtering
them out.
