As illustrated in the following figu

37、re the PCOs for the communication between the systems are Gm, Mw, Ic and Isc. Each component can play role of SUT.

39、re The target SUT to be covered by the test purposes of TS 186 016-2 3 address the IMS functional entities that are accessible via the following interfaces: Gm, Mw, Ic and ISC. This clause introduces the test configurations that have been used for the test purpose definitions. Depending on the speci

40、fic configuration the test system (TS) simulates the behaviour of the UE or another IMS communicating with the SUT. Figures 3 to 7 provide the different configurations in detail. The test configuration is specified in the context of TTCN-3 functions (e.g. f_cf_1UeUp). The letters “P“, “S“, “I“ and “

41、B“ etc. indicate the CSCFs within the SUT or TS. If applicable used identifiers on user profiles (see clause 5.3.2.4) have also been added in the figures (e.g. “PCSCFwithHomeUE“ corresponds to TTCN-3 constant c_userProfile_PCSCFwithHomeUE). 4.3.1 Test configuration 4.3.1.1 Configuration using Gm int

47、ce (TCI) and the TTCN-3 Runtime Interface (TRI), which specify the interface between Test Management (TM) and TTCN-3 Executable (TE) entities, and TE, SUT Adapter (SA) and Platform Adapter (PA) entities, respectively. Out of these two interfaces the TRI has been standardized in ES 201 873-5 9, where

48、as the specification and implementation of the TCI is in ES 201 873-6 10. The part of TS that deals with interpretation and execution of TTCN-3 modules, i.e. the Executable Test Suite (ETS), is shown as part of the TTCN-3 Executable (TE). This ETS corresponds either to the executable code produced b

49、y a TTCN-3 compiler or a TTCN-3 interpreter from the TTCN-3 ATS in a TS implementation. The remaining part of the TS, which deals with any aspects that cannot be concluded from information being present in the TTCN-3 ATS alone, can be decomposed into Test Management (TM), SUT Adapter (SA) and Platform Adapter (PA) entities. In general, these entities cover a TS user interface, test execution control, test event logging, communication of test data with the SUT and timer implementation. The part of SA used for SIP message tr
