The stage 3 description respects the requirements to several network entities and also to requirements regarding to e

20、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 t

21、he 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 perform the test of the AS using any NNI (Mw, Mg, Mx) interface (consider figure 2). In case only the G

22、m interface is accessible this shall be used instead. In this case, be aware that the verification of several requirements is impeded.
