Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No

Foreword This ETSI Guide (EG) has been produced by ETSI Technical Committee Methods for Testing a
23、nd Specification (MTS). Introduction In the context of the present document, an Implementation Conformance Statement (ICS) proforma is a document in the form of a questionnaire, part of a telecommunication specification (e.g. protocol, interface, telecommunication service). It needs to be filled in
24、by the supplier of an implementation, and when completed, becomes an ICS. The objective of the ICS is to provide a statement of which capabilities and options of the telecommunication specification have been implemented. The ICS is used in two contexts: - for conformance testing purposes: it is main
25、ly used to check the static conformance of the implementation, and to select and parameterize the tests; - outside the conformance testing context: it is used to provide information on the capabilities supported by the implementation - as an identity card, in order for example, to have an idea of th
26、e chances of interoperability of two implementations. The questions in an ICS proforma are presented in the form of tables. EXAMPLE: Table A.1: Call directions Item Call direction Reference Status Support 1 Incoming call 1.1, 5.4.3 m 2 Outgoing call 1.2, 7.1.2.1 o With the following conventions: - “
27、Incoming call“ stands for “Is incoming call supported?“; - “Outgoing call“ stands for “Is outgoing call supported?“; - “m“ in the status column stands for “it is mandatory to support it“; - “o“ in the status column stands for “it is optional to support it“; - the supplier of the implementation needs
28、 to answer “Yes“ or “No“ in the support column. END of EXAMPLE ETSI ETSI EG 201 058 V1.2.4 (2003-09) 7 ISO/IEC 9646-7 3 specifies requirements for the development of ICS proforma. The present document has been developed to harmonize the ICS proforma produced by the different groups in ETSI. The need
29、 for harmonizing the styles in ETSI comes from the fact that: - different styles may confuse the users of standards; - in order to meet quality criteria such as readability, it is necessary to select notations from those allowed by ISO/IEC 9646-7 3; - the ETSI groups developing ICS proforma are gene
30、rally not very familiar with conformance testing and ICS. A very open standard like ISO/IEC 9646-7 3 leaves enough options to be confusing. Consequently, the development groups encounter difficulties when trying to decide which notations should be adopted; - a given ICS proforma, and subsequent vers
31、ions of it, are generally not produced by the same group of specifiers. Unusual notations may confuse the new specifiers; - a style harmonization will foster the development of ICS editors and interpreters (tools able to automatically interpret an ICS when parameterizing or selecting test cases, or
32、performing a static conformance review). The criteria retained for defining a style were the readability for the users, the facility of production and maintenance for the specifiers. Some comments from toolmakers (i.e. tools for editing and interpreting ICS proforma) have also been taken into accoun
33、t. ETSI ETSI EG 201 058 V1.2.4 (2003-09) 8 1 Scope The present document is intended to be used by specifiers of Implementation Conformance Statement (ICS) proforma. It provides recommendations and practical guidance in order to produce ICS proforma and profile requirement lists. It contains also a t
34、emplate of an ICS proforma specification for a base standard and an example of requirement list for a profile. The present document does not cover Managed Object Conformance Statement (MOCS) proforma. Within ETSI, ICS proforma are generally produced using MicrosoftWord for Windows. The present docum
35、ent gives specific guidance on its use, in this particular context. The electronic version of the template of a base specification ICS proforma, and the example of a requirement list are available. The electronic version of the template should be used as the physical basis of an actual ICS proforma,
36、 with minimum modifications. The present document should be applied in ETSI for the development of new ICS proforma. Existing ICS proforma do not have to be modified in order to comply with the present document. Moreover, when work is being performed in collaboration with other standardization insta
37、nces (e.g. at an international level, either in the form of an ETSI profiling activity on a base ICS proforma specification provided by ITU-T or ISO, or in the form of a planned contribution) the present document should be used to the extent necessary to allow compatibility with any practice in use
38、in the concerned group. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For a spec
39、ific reference, subsequent revisions do not apply. For a non-specific reference, the latest version applies.

43、r information object (see ETS 300 406) NOTE 1: A base specification is defined differently to a profile, which constrains optionalities in one or several base specifications. NOTE 2: The present document does not deal with information objects. reference specification: a reference specification is a
44、standard which specifies a base specification, or a set of base specifications, or a profile, or a set of profiles, and for conformance against which the ICS proforma and test specifications are written NOTE: This definition extends the definition in ETS 300 406 1, to the specification for which the
45、 ICS proforma is written. implementation: the implementation of the reference specification, which claims to conform to the reference specification NOTE: See ISO/IEC 9646-1 2. Implementation Conformance Statement (ICS) proforma: a document, in the form of a questionnaire, designed by the specifier,
46、which when completed for an implementation or system becomes the ICS NOTE: See ISO/IEC 9646-1 2. Implementation Conformance Statement (ICS): a statement made by the supplier of an implementation or system claimed to conform to a given specification, stating which capabilities have been implemented.
47、It is a completed ICS proforma. The ICS can take several forms: protocol ICS (PICS), profile ICS, information object ICS NOTE: See ISO/IEC 9646-1 2. base specification ICS: an ICS related to a base specification. A Protocol Implementation Conformance Statement (PICS) is a particular case of base spe
48、cification ICS, applied to base specifications of protocols ICS template: a template which can be used as the basis for developing an ICS proforma NOTE: Annex A of the present document contains an ICS template. 3.2 Abbreviations For the purposes of the present document, the following abbreviations a
