17、 Test suite structure 5.1 Configuration This Recommendation is to test the signalling and procedural aspects of the stage 3 requirements as described in ETSI TS 124 607. The stage 3 description describes the requirements for several network entities and also the requirements regarding for terminal d
18、evices. Therefore, several interfaces (reference points) are addressed to satisfy the test of the different entities. Rec. ITU-T Q.3943.2 (04/2013) 3 Therefore, to test the appropriate entities, the configurations below are applicable: 5.1.1 Testing of the AS The AS entity is responsible for perform
19、ing and managing services. The ISC interface is the appropriate access point for testing (see Figure 2). ApplicationserverImplementation under testTestsystemISCQ.3943.2(13)_F02TestsystemISCFigure 2 Applicable interface to test AS functionalities If the ISC interface is not accessible, it is also pos
20、sible to perform the test of the AS using any NNI (Mw, Mg, Mx) interface (see Figure 3). In case only the Gm interface is accessible, this interface can be used instead for testing, but the verification of all requirements may not be possible.

Groups are organized ac
22、cording 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 1).

23、esenting group reference according to TSS = sequential number (001 to 999) 6.1.2 Test strategy As the base standard ETSI TS 124 607 contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ITU-T Q.3943.1. 4 Rec.
24、ITU-T Q.3943.2 (04/2013) The criteria applied include the following: only the requirements from the point of view of the T or coincident S and T reference point are considered; whether or not a test case can be built from the TP is not considered. 6.2 Network TPs for OIP and OIR 6.2.1 Requirements o
