To evaluate protocol conformance of a particular implementation, it is necessary to have a statement of which
capabilities and options have been implemented for a telecommunication specification. Such a statement is called a
Protocol Implementation Conformance Statement (PICS).

1 Scope
The present document provides the Protocol Implementation Conformance Statement (PICS) pro forma for the test
specification for the NAS protocol on the S1-MME interface as specified in ETSI TS 124 301 [1] in compliance with
the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 [3] and ETSI
ETS 300 406 [4].
The supplier of a protocol implementation which is claimed to conform to ETSI TS 124 301 [1] is required to complete
a copy of the PICS pro forma provided in annex A of the present document and is required to provide the information
necessary to identify both the supplier and the implementation.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in ETSI TS 124 301 [1] and the following
apply:
PICS pro forma: document, in the form of a questionnaire, designed by the protocol specifier or conformance test suite
specifier, which, when completed for an OSI implementation or system, becomes the PICS
NOTE: See ISO/IEC 9646-1 [2].
Protocol Implementation Conformance Statement (PICS): statement made by the supplier of an Open Systems
Interconnection (OSI) implementation or system, stating which capabilities have been implemented for a given OSI
protocol
NOTE: See ISO/IEC 9646-1 [2].
static conformance review: review of the extent to which the static conformance requirements are met by the IUT,
accomplished by comparing the PICS with the static conformance requirements expressed in the relevant standard(s)
NOTE: See ISO/IEC 9646-1 [2].
3.2 Abbreviations
For the purposes of the present document, the abbreviations given in ETSI TS 124 301 [1] apply.
4 Conformance
A PICS pro forma which conforms to this PICS pro forma specification shall be technically equivalent to annex A, and
shall preserve the numbering and ordering of the items in annex A.
A PICS which conforms to this PICS pro forma specification shall:
a) describe an implementation which claims to conform to ETSI TS 124 301 [1];
b) be a conforming ICS pro forma which has been completed in accordance with the instructions for completion
given in clause A.1;
c) include the information necessary to uniquely identify both the supplier and the implementation.

Annex A (normative):
PICS pro forma
A.1 The right to copy
Notwithstanding the provisions of the copyright clause related to the text of the present document, ETSI grants that
users of the present document may freely reproduce the PICS pro forma in this annex so that it can be used for its
intended purposes and may further publish the completed PICS pro forma.
A.2 Guidance for completing the ICS pro forma
A.2.1 Purposes and structure
The purpose of this PICS pro forma is to provide a mechanism whereby a supplier of an implementation of the
requirements defined in relevant specifications may provide information about the implementation in a standardized
manner.
The PICS pro forma is subdivided into clauses for the following categories of information:
- instructions for completing the PICS pro forma;
- identification of the implementation;
- identification of the protocol;
- PICS pro forma tables (for example: Major capabilities, etc.).
A.2.2 Abbreviations and conventions
This annex does not reflect dynamic conformance requirements but static ones. In particular, a condition for support of
a PDU parameter does not reflect requirements about the syntax of the PDU (i.e. the presence of a parameter) but the
capability of the implementation to support the parameter.
In the sending direction, the support of a parameter means that the implementation is able to send this parameter (but it
does not mean that the implementation always sends it).
In the receiving direction, it means that the implementation supports the whole semantic of the parameter that is
described in the related protocol specification.
As a consequence, PDU parameter tables in this annex are not the same as the tables describing the syntax of a PDU in
the reference specification.
The PICS pro forma contained in this annex is comprised of information in tabular form in accordance with the
guidelines presented in ISO/IEC 9646-7 [3].
Item column
The item column contains a number which identifies the item in the table.
Item description column
The item description column describes in free text each respective item (e.g. parameters, timers, etc.). It implicitly
means "is supported by the implementation?".
ETSI

8 ETSI TS 103 530-1 V1.1.1 (2018-01)
Reference column
The reference column gives reference to the relevant sections in core specifications.
Status column
The various status used in this annex are in accordance with the rules in table A.1.
Table A.1: Key to status codes
Status code Status name Meaning
m mandatory The capability shall be supported. It is a static view of the fact that the
conformance requirements related to the capability in the reference
specification are mandatory requirements. This does not mean that a given
behaviour shall always be observed (this would be a dynamic view), but that it
shall be observed when the implementation is placed in conditions where the
conformance requirements from the reference specification compel it to do so.
For instance, if the support for a parameter in a sent PDU is mandatory, it does
not mean that it shall always be present, but that it shall be present according
to the description of the behaviour in the reference specification (dynamic
conformance requirement).
o optional The capability may or may not be supported. It is an implementation choice.
n/a not applicable It is impossible to use the capability. No answer in the support column is
required.
c. conditional The requirement on the capability ("m", "o", "n/a") depends on the support of
other optional or conditional items. is the identifier of the conditional
expression.
o. qualified optional For mutually exclusive or selectable options from a set. is the
identifier of the group of options, and the logic of selection of the options.

Mnemonic column
The Mnemonic column contains mnemonic identifiers for each item.
Support column
The support column shall be filled in by the supplier of the implementation. The following common notations, defined
in ISO/IEC 9646-7 [3], are used for the support column:
Y or y supported by the implementation
N or n not supported by the implementation
N/A, n/a or - no answer required (allowed only if the status is N/A, directly or after evaluation of a conditional
status)
References to items
For each possible item answer (answer in the support column) within the PICS pro forma there exists a unique
reference, used, for example, in the conditional expressions. It is defined as the table identifier, followed by a solidus
character "/", followed by the item number in the table.
EXAMPLE: A.5/4 is the reference to the answer of item 4 in table A.5.
A.2.3 Instructions for completing the PICS pro forma
The supplier of the implementation may complete the PICS pro forma in each of the spaces provided. More detailed
instructions are given at the beginning of the different clauses of the PICS pro forma.
