15、is Recommendation is to test the signalling and 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 the requirements regarding end devices. Consequently several interfaces (reference p

16、oints) are addressed to satisfy the test of the different entities. In order to test the appropriate entities the configurations below are applicable: Testing of user equipment: There are several requirements regarding end devices. Therefore a special configuration is applicable (see Figure 5-1.1).

17、Figure 5-1.1 Applicable configuration to test the user equipment 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 numbered, starting at 001, within each group. Groups are organized according to the test suit
