Specialist Task Force 368:
Tests on Supplementary Services ACR and CB, MCID, CUG, TIP and TIR

Who we are:

Team Leader: Bostjan Pintar
Team Members: Peter Schmitting
Johan Petersen

What we do:

The STF will produce the following deliverables, for TB approval:

  • DTS/INT-00003-3 ACR/CB; Anonymous Communication Rejection and Communication Barring conformance   testing; Part 3: ATS Conformance Testing; Part 3: ATS 
  • DTS/INT-00004-3 Malicious Communication Identification (MCID); Conformance Testing; Part 3: ATS DTS/INT-00006-3           User Group (CUG); Conformance Testing; Part 3: ATS 
  • DTS/INT-00007-3 Terminating Identification Presentation (TIP) and Terminating Identification Restriction (TIR) conformance testing; Part 3: ATS

The Abstract Test Suites (ATS) that will be included in the deliverables implement a standardized set of test purposes on the related protocol specifications using the Testing and Test Control Notation TTCN-3. After developing the TTCN-3 specification the test suites will be executed against some protocol implementation for the purpose of ATS validation.

For more details, see our Terms of Reference

Why we do it:

Experience with the development of other standards has shown that involvement of experts on conformance testing of protocols requires highly specialised knowledge in testing methodology, TTCN language and dedicated tools. There is an advantage if testing experts are disjoint from experts developing the protocol specifications. In addition, the development of this kind of specifications requires significant effort and it cannot be expected that this effort can be provided on a voluntary basis. Hence the involvement of testing experts is needed in order to assure timely completion and high quality of the Test Specifications. These testing experts are not available on TC TISPAN level and need to be recruited on a funded basis. The experts will use dedicated software tools available at ETSI.

Time plan for the work:

We intend to complete Phase 1: Developing the test specifications by May 2009.
