This clause i

21、ntroduces the test configurations that have been used for the definition of test purposes. Depending on the specific configuration the test system (TS) simulates the behaviour of one or more CSCFs, HSS or SLF communicating with the system under test (SUT). NOTE: In a real operating network the diffe

In the following test architecture figures the Diameter Agent is not explicitly depicted as it is seen as a transparent message handler for conformance testing purpose

28、re (TSS) and Test Purposes (TP) 5.1 Test Suite Structure 5.1.1 TP naming convention TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Table 1: TP identifier naming convention scheme Identifier: _ = Test Purpose: fixed to “TP“ = Interface: CX or DX = typ

30、2 Test strategy As the base standards ETSI TS 129 228 1 and ETSI TS 129 229 2 contain no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 103 289-1 3. 5.1.3 TP structure Each TP has been written in a manner w

31、hich is consistent with all other TPs. The intention of this is to make the TPs more readable and checkable. A particular structure has been used which is illustrated in table 2. This table should be read in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehen

32、sion of table 2.

NOTE 2: All messages are considered as “valid and compatible“ unless otherwise specifie

37、d in the test purpose. This includes the presence of all mandatory AVPs as specified in IETF RFC 3588 7 and in ETSI TS 129 229 2. NOTE 3: An AVP can be embedded into another AVP. This is expressed by indentations, e.g. if Message1 contains AVP1 and AVP2 where AVP1 has AVP3 embedded this will be expr

38、essed like this: sends/receives Message 1 containing AVP1 containing AVP3indicating . containing AVP2indicating . NOTE 4: In addition to the clause number there could be specified also following syntaxes: a) Paragraph symbol can appear after clause number to make reference more precise. A paragraph

39、consists of one or more sentences and paragraph ends with newline. b) Syntax like “item X-Y-Z-.“ could be also part of reference and it can stand beside clause where X specifies item number and Y and Z are standing to represent number of dashed line. (ex. “item 3-4-1“ points to the item 3 and 4thdas

40、hed line and 1stdashed line present within previously mentioned 4thdashed line) above syntax can be present within parenthesis or separated with/symbol. 5.2 Test Purposes 5.2.0 PICS references All PICS items referred to in this clause are as specified in ETSI TS 103 289-1 3 unless indicated otherwis
