15、st suite structure 4.2 Configuration The scope of the present document is to test the signalling and procedural aspects of the stage 3 requirements as described in ETSI TS 124 629 1. The stage 3 description respects the requirements to several network entities and also to requirements regarding to e

16、nd devices. 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 applicable: Testing of the Application Server: This entity is responsible to perform the service. Hence the

17、 ISC interface is the appropriate access point. Figure 4.2.1 points to this. ETSI ETSI TS 101 594-2 V6.1.1 (2018-06)7Figure 4.2.1: Applicable interface to test AS functionalities If the ISC interface is not accessible it is also applicable to perform the test of the AS using any NNI (Mw, Mg, Mx) int

18、erface (consider figure 4.2.2). In case only the Gm interface is accessible this shall be used instead. In this case, be aware that the verification of several requirements is impeded. Figure 4.2.2: Applicable interfaces to test using the (generic) NNI interface Figure 4.2.2 illustrates the usage of

19、 any NNI interface. Testing of User Equipment: There are several requirements regarding to the end devices. Therefore a special configuration appears.

20、 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 table 5.1.1). Table 5.1.1: TP identifier naming convention s

21、cheme Identifier: _ = supplementary service: e.g. “ECT“ = type of IUT: U User N Network = group 2 digit field representing group reference according to TSS = sequential number (001-999) 5.1.2 Test strategy As the base standard ETSI TS 124 629 1 contains no explicit requirements for testing, the TPs

22、were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 101 594-1 2.
