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

17、equirements regarding to end 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 perf

18、orm the service. Hence the 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 figur

19、e 2). In case only the Gm interface is accessible this shall be used instead. In this case, be aware that the verification of several requirements is impeded.

23、ch test requirement a TP is defined. 5.1.1 TP naming convention TPs are numbered, starting at 001, within each group. Groups are organized according 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). Table 1:

24、 TP identifier naming convention scheme Identifier: _ = supplementary service: e.g. “CC“ = type of IUT: U User - equipment N Network = group 2 digit field representing group reference according to TSS = sequential number (001 to 999) 5.1.2 Test strategy As the base standard TS 183 042 1 contains no

25、explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification TS 186 021-1 2. The criteria applied include the following: whether or not a test case can be built from the TP is not considered. ETSI ETSI TS 186 021-2 V2.1.1 (2009-
