16、d procedural aspects of the stage 3 requirements as described in ITU-T Q.3623 v.1. The stage 3 description respects the requirements of several network entities and also requirements regarding end devices. Therefore several interfaces (reference points) are addressed to satisfy the test of the diffe

17、rent entities. To test the appropriate entities the configurations below are applicable: Testing of the application server (AS): The application server performs the service. Hence the IM-CN service control (ISC) interface is the appropriate access point as shown in Figure 5.1-1. Figure 5.1-1 Applica

The Gm interface shall be used instead, if it is the only interface available. In this case, be aware that verification

19、of several requirements is impeded. Figure 5.1-2 Interfaces applicable to testing using the (generic) NNI Figure 5.1-2 illustrates the usage of any NNI. 6 Test purposes 6.1 Introduction For each test requirement a test purpose (TP) is defined. 6.1.1 TP naming convention Test purposes (TPs) are numbe
