The stage 3 descript

Therefore several interfaces (reference points) are addressed to satisfy the test of the different entities. Therefore, to test the appropriate entities, the configurations below are applicab
19、le: Testing of the Application Server: This entity is responsible to perform the service. Hence the ISC interface is the appropriate access point. Figure 1 points to this. Figure 1: Applicable interface to test AS functionalities If the ISC interface is not accessible it is also applicable to perfor

In this case, be aware that the verification of several requirements is impeded. ETSI ETSI TS 186 014-2 V3.2.1 (2015-06)8 Figure 2: Applicable interf

22、 Purposes (TP) 5.1 Introduction 5.1.1 TP naming convention TPs are numbered, starting at 001, within each group. Groups are organized according to the TSS. Additional references are added to identify the actual test suite and whether it applies to the network or the user (see figure 4). Identifier:
23、_ = supplementary service: e.g. “CDIV“ = type of IUT: U User N Networkyyy service = group 2 digit field representing group reference according to TSS = sequential number (001-999) Figure 4: TP identifier naming convention scheme 5.1.2 Test strategy As the base standard ETSI TS 124 604 1 contains no
24、explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 186 014-1 2.
