35、 In order to execute this test suite the SA should support: communication channel handling (at least UDP and possibly also TCP); IPv4 transport. 4.3.2.4 Encoding/Decoding requirements 4.3.2.4.1 Encoding/Decoding System requirements for basic SIP messages/headers SIP is a text-based protocol that all
36、ows different syntactical presentations of the same information. In general, an implementation of this ATS should use an EDS to parse received encoded messages into TTCN-3 type structures and values, and encode structured TTCN-3 type structures and values into encoded messages. This EDS is not part
37、of the ATS. Still all encoded messages, i.e. the messages as they are transmitted by the SA to or received by the SA from the SUT, shall be logged. The following terms shall be used for the conventions defined below: Syntactic delimiter syntactic delimiters are characters like “=“ or “;“ that are us
38、ed to separate encoded values. LWS Linear White Spaces as defined in RFC 3261 4. Parameter name name of header parameters as defined in RFC 3261 4. ETSI ETSI TS 186 018-3 V2.2.1 (2010-11)14Parameter value the value of a parameter as defined in RFC 3261 4. Undefined method an undefined method is a me
39、thod 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 4. Unexpected header an unexpected header is a header, which shall not be
40、present in a specific request message. This definition complies with the definition of NOT APPLICABLE in RFC 3261 4, clause 20 for request messages. Decoder requirements TTCN-3 fields should not contain syntactic delimiters like white space, semicolon, equal characters etc. in fully decoded fields.
41、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 following decoding rules shall be applied by the
42、 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 is used for a SIP parameter value. The followin
43、g 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 message is subject to logging as defined in clau
44、se 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 4 allows for multiple header field values of the same kind to either arrive in one or multiple occurrences of the corresponding header field. The SI
45、P 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 values. This can be achieved by adding the value
46、of, e.g. the second received Via header field as the last value to the value(s) of the first Via header field. Encoder requirements Encoders shall follow all encoding rules that are defined in RFC 3261 4 when encoding structured values received from templates. This applies in particular to but it is
47、 not restricted to clause 7.3.1 of RFC 3261 4. Values of type Raw shall be sent to the SUT without any modification. 4.3.2.5 Platform adaptation requirements For the execution of this test suite implementations of the following external functions have to be provided (cp. module LibSip_Steps): 1) rnd
48、Str() return charstring; returns a random charstring; 2) putInLowercase(charstring par_string) return charstring; returns the equivalent string in lower case; 3) getIpAddr(charstring host_name) return charstring; resolves a domain name to its equivalent IPv4 address.
