6.1 Test method

34.123-33GPPPart 3: Abstract test suite (ATS)TSUser Equipment (UE) conformance specification

The distributed single party test method is used for the UE testing. The lower tester configures the emulator and communicates with the UE under test via the emulator. An upper tester interfaces UE as (E)MMI.

All common parts in 3GPP TS 34.108 [3], 3GPP TS 34.109 [4] and 3GPP TS 34.123-2 [2] are developed in a TTCN library including the declarations, default constraints, preambles and postambles. They have the following characteristics:

– Very complex;

– Worked in different layers;

– Including data representing the radio parameters for SS setting and the data representing the UE capabilities (PICS parameters);

– Including the generic procedures to bring the UE into certain test states or a test mode (C-plane);

– Setting RABs at U-plane and SRBs in C-plane;

– Being used by every test cases no matter which layer the test case belongs to;

– No affect on the test verdict of PASS or FAIL.

The layer-specific test cases have the characteristics:

– relatively simple and straight forward;

– having narrow test scope and test purposes;

– test scenarios in a single layer (one PCO);

– assigning the test verdict.
