Foreword This Technical Specification (TS) has been produced by ETSI Technical Committee Methods for Testing and Specification (MTS). The present document is part 3 of a multi-part deliverable covering Conformance

19、Test Specification for SIP (IETF RFC 3261 1), as identified below: Part 1: “Protocol Implementation Conformance Statement (PICS) proforma“; Part 2: “Test Suite Structure and Test Purposes (TSS Part 3: “Abstract Test Suite (ATS) and partial Protocol Implementation eXtra Information for Testing (PIXIT

20、) proforma“. ETSI ETSI TS 102 027-3 V4.2.5 (2008-01) 6 1 Scope The present document specifies the Abstract Test Suite (ATS) for the Session Initiation Protocol (SIP) as defined in RFC 3261 1. The objective of the present document is to provide a basis for conformance tests for SIP equipment giving a

21、 high probability of inter-operability between different manufacturers SIP equipments. Annex A provides the TTCN-3 part of the ATS. Annex B provides the Partial Protocol Implementation Extra Information for Testing (PIXIT) Proforma of the ATS. Annex C provides the Protocol Conformance Test Report (P

22、CTR) Proforma of the ATS. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

ETSI ETSI TS 102 027-3 V4.2.5 (2008-01) 10Parameter value the value of a parameter as defined in RFC 3261 1. Undef

32、ined method an undefined method is a method other than: “INVITE“, “ACK“, “OPTIONS“, “BYE“, “CANCEL“ and “REGISTER“. Undefined header an undefined header is a header other than general-header, entity-header, request-header and response header as defined in RFC 3261 1. Unexpected header an unexpected

33、header is a header, which shall not be present in a specific request message. This definition complies to the definition of NOT APPLICABLE in RFC 3261 1, section 20 for request messages. 4.3.2.1 Decoding requirements TTCN-3 fields should not contain syntactic delimiters like white space, semicolon,

34、equal characters etc. in fully decoded fields. Instead the information provided by a parser shall be used to build the decoded message in TTCN-3. Decoded messages shall use the TTCN-3 enumeration types where ever appropriate, e.g. for the method and the header field name. For charstring fields the f

35、ollowing decoding rules shall be applied by the EDS: 1) Subsequent LWS shall compress to a single space character “ “. 2) Decoded parameter names shall use only lower case letters. 3) Parameter values containing an integer value shall be decoded to a TTCN-3 integer value where a TTCN-3 integer type

36、is used for a SIP parameter value. The following decoding rules shall be applied by the EDS to each received message in the following order: 1) In case a request message indicating an undefined method is received by the test system, the message shall not be passed in the TE to the ETS. However the m

37、essage is subject to logging as defined in clause 4.3.3 (“Logging conventions“). 2) In case an undefined header has been received the header field shall be decoded as UndefinedHeader field. RFC 3261 1 allows for multiple header field values of the same kind to either arrive in one or multiple occurr

38、ences of the corresponding header field. The SIP ATS has been written assuming only the first format. Therefore, should the EDS receive multiple header fields of the same kind in a SIP message, e.g. of a Via header field, it shall convert them into the equivalent single header field with multiple va

39、lues. This can be achieved by adding the value of, e.g. the second received Via header field as the last value to the value(s) of the first Via header field. 4.3.2.2 Encoding requirements Encoders shall follow all encoding rules that are defined in RFC 3261 1 when encoding structured values received

40、 from templates. This applies in particular to but it is not restricted to section 7.3.1 of RFC 3261 1. Values of type Raw shall be send to the SUT without any modification. 4.3.3 Logging conventions As the ATS defines on an abstract level the message exchange between TS and SUT the messages encoded

41、 messages send and received shall be logged. The TM entity in the TS shall provide access to this log. 5 Untestable Test Purposes (TP) This clause gives a list of TP, which are not implemented in the ATS due to the chosen ATM or other restrictions: None.

42、TS conventions The ATS conventions are intended to give a better understanding of the ATS, but they also describe the conventions made for the development of the ATS. These conventions shall be considered during any later maintenance or further development of the ATS. The ATS conventions contain two

43、 clauses, the naming conventions and the implementation conventions. The naming conventions describe the structure of the naming of all ATS elements. The implementation conventions describe the functional structure of the ATS. 6.1 Naming conventions 6.1.1 Type definitions This clause describes the n

44、aming conventions used for structured and unstructured types as well as for the field names of structured types. 6.1.1.1 General Type identifiers use mixed cased with the first letter of each internal word capitalized. EXAMPLE 1: RequestLine Field identifiers use mixed cased with a lowercase first l

45、etter. Internal words start with a capital letter. EXAMPLE 2: requestLine Names of type as well as field identifiers attempt to follow the naming chosen of ABNF elements (if a counterpart exists) as closely as possible. EXAMPLE 3: NameAddr hostName In case type and identifier names should give a hin

46、t on their structure the term describing the structure should be separated with an underscore (“_“) at the end of the name. EXAMPLE 4: CommaParam_List ContactBody_Union 6.1.1.2 PDU Type Definition Names of types used as PDUs follow the general conventions as defined in clause 6.1.1.1. EXAMPLE: Reque

47、st 6.1.2 Template definition Template identifiers consist of the type name, an identifier denoting whether the template is for sending or receiving and a sequential number. EXAMPLE: Request_r_1 denotes a template from type Request that is intended for reception. CommaParam_List_s_25 denotes a templa

48、te from type CommaParam_List that is intended for sending. The sequential number is used only to distinguish between templates for the same type and direction and includes no other information. ETSI ETSI TS 102 027-3 V4.2.5 (2008-01) 126.1.3 Constant declarations Identifiers for either internal or e

49、xternal constants, use only uppercase letters. Internal words are separated by an underscore (“_“). EXAMPLE: SIP_VERSION 6.1.4 Enumeration declarations While identifiers for the enumeration type follow the conventions as defined in clause 6.1.1. “Type definitions“, enumerations elements use only uppercase letters, which are suffixed by “_E“ to distinguish them from constants. Internal words are separated by an underscore character (“_“). EXAMPLE: Enumeration type FieldName Enumeration value FROM_E 6.1.5 Module parameter declarations
