6.16 Supplementary Service test method and architecture

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

6.16.1 Test configuration

The SS test method is shown in Figure 6A.2.

The upper tester triggers the UE to perform the supplementary service task required by the test case.

The supplementary services are encoded in a TCAP [52] ROSE component [53] of the facility information element [51] conveyed in the NAS messages. The facility information element is encoded in BER in TTCN referred to 3GPP TS 24.080 [50], clause 3.6.1 and 3GPP TS 29.002 [51], clause 17.1.1.
