Groups are organized according to the TSS. Table 1: TP identifier naming convention scheme
27、 Identifier: _ = Test Purpose: fixed to “TP“ Interface: RF or RO = type of IUT: CDF, OCF or CTF = group MS Message syntax TC Type of Charging EC Error Cases CH Tariff Changes RE Re-authorization FH Failure Handling FA Failover CP Credit Pooling OP Other procedures (2, clause 6.5) = sequential number
28、 (01 to 99) 5.1.2 Test strategy As the base standards in ETSI TS 132 260 1 and ETSI TS 132 299 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 103 374-1 4. 5.1.3 TP structure Each TP has been wr
29、itten in a manner which 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. Table 2 should be read in conjunction with any TP, i.e. please use a TP as an example to facilitate th

35、This includes the presence of all mandatory AVPs as specified in IETF RFC 3588 8 and in ETSI TS 132 299 2, clauses 6.2.2, 6.2.3, 6.4.2 and 6.4.3. 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 t
