Introduction 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
20、is called a Protocol Implementation Conformance Statement (PICS). ETSI ETSI TS 102 790-1 V3.1.1 (2014-07)51 Scope The present document provides the Protocol Implementation Conformance Statement (PICS) proforma for the IP Multimedia core network Subsystem (IMS) equipment supporting the Internet Proto
21、col (IP) multimedia call control protocol based on Session Initiation Protocol (SIP) and Session Description Protocol (SDP) as specified in TS 124 229 1 in compliance with the relevant requirements and in accordance with the relevant guidance given in ISO/IEC 9646-7 4 and ETS 300 406 5. The supplier
22、 of a protocol implementation which is claimed to conform to TS 124 229 1 is required to complete a copy of the PICS proforma provided in annex A of the present document and is required to provide the information necessary to identify both the supplier and the implementation. 2 References References
23、 are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced document

31、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 i.1. Protocol Implementation Conformance Statement (PICS): statement made by the supplier of an Open Systems I
32、nterconnection (OSI) implementation or system, stating which capabilities have been implemented for a given OSI protocol NOTE: See ISO/IEC 9646-1 i.1. static conformance review: review of the extent to which the static conformance requirements are met by the IUT, accomplished by comparing the PICS w
33、ith the static conformance requirements expressed in the relevant standard(s) NOTE: See ISO/IEC 9646-1 i.1. 3.2 Abbreviations For the purposes of the present document, the abbreviations given in TS 124 229 1 apply. 4 Conformance A PICS proforma which conforms to this PICS proforma specification shal
34、l 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 proforma specification shall: a) describe an implementation which claims to conform to TS 124 229 1; b) be a conforming ICS proforma which has been comple
35、ted 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. ETSI ETSI TS 102 790-1 V3.1.1 (2014-07)7Annex A (normative): PICS proforma Notwithstanding the provisions of the copyright c
36、lause related to the text of the present document, ETSI grants that users of the present document may freely reproduce the PICS proforma in this annex so that it can be used for its intended purposes and may further publish the completed PICS. A.1 Guidance for completing the ICS proforma A.1.1 Purpo
37、ses and structure The purpose of this PICS proforma 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 proforma is subdivided into clauses for the
38、 following categories of information: - instructions for completing the PICS proforma; - identification of the implementation; - identification of the protocol; - PICS proforma tables (for example: Major capabilities, etc.). A.1.2 Abbreviations and conventions This annex does not reflect dynamic con
39、formance 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
40、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 main part of the present document.
41、 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 proforma contained in this annex is comprised of information in tabular form in accordance with the guidelines presented in ISO/IEC 9646-7 4. I
42、tem 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?“. Reference column The refere
43、nce column gives reference to the relevant sections in core specifications. ETSI ETSI TS 102 790-1 V3.1.1 (2014-07)8Status 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 capabi
44、lity 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 obse
45、rved 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 accordi
46、ng 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. c
47、onditional The requirement on the capability (“m“, “o“ and “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,
48、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 4, are used for the suppor
49、t 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 proforma 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 i
