ETSI ETSI TS 186 009-2 V2.2.1 (2011-03)126.1.1 Test purpose (TP) naming convention For each test requirement a Test Purpose (TP) is defined. All test purposes belong to the main group ISUP_S

44、IP_Interworking. Groups are organized according to the test suite structure (TSS). Each test purpose is presented in a separate table. The first row of the table contains the following items: TP Identifier of the test purpose; SIP reference the reference to the requirement in the DSS1 layer 3 Recomm
