14、e present document is to test the signalling and procedural aspects of the stage 3 requirements as described in 1. The stage 3 description respects the requirements to several network entities and to requirements regarding to end devices. Therefore, several interfaces (reference points) are addresse
15、d 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 ISC interface is the appropriate access point. Figure 4-1 points to th
16、is. Figure 4-1: 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) interface (consider figure 4-2). In case only the Gm interface is accessible this shall be used instead. In this case,
17、 be aware that the verification of several requirements is impeded. ETSI ETSI TS 101 588-2 V6.1.1 (2018-07)7 Figure 4-2: Applicable interfaces to test using the (generic) NNI interface Testing of User Equipment: There are several requirements regarding to the end devices. Therefore, a special config

Groups are organized according to
19、 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).
