1 Maximilian Frey P1016 MINIT Mobile IP-Network Integration Testing

2 Maximilian Frey CONTENT History of testing at Eurescom Scope of the Project Participants Concepts for Testing UMTS Test Architectures PCOs State of the Project ETSI Workitems Conclusion

3 Maximilian Frey History of testing at EURESCOM P104: ISDN End-to-End Testing P412: Methodology and Tools for ISDN Network Integration and Traffic Route Testing P613: Methods and tools for B-ISDN and N-ISDN Network Integration Testing ATS for end-to-end interworking tests between GSM, ISDN, PSTN P919: Evolution of integrated fixed and mobile networks ATS for end-to-end tests for GSM and GPRS P1016: Mobile IP Network Integration Testing ATS for end-to-end tests between UMTS, GPRS, GSM, ISDN, PSTN

4 Maximilian Frey Scope of the Project End-to-End: – UMTS-CS and GSM, ISDN, PSTN including use channel tests – UMTS-PS and IP IP-Network-Integration Tests: –Application Tests between UMTS-PS and Application-Servers –Performance Tests between UMTS-PS and IP-Network: Generation and Comparison of IP-Packets (different Phases: duration, number of IP-packets) Core-Network-Interfaces: –ISUP, INAP CS-1/CS-2, CAP Ph.1-Ph.3

5 Maximilian Frey Participating Companies CSELT, Italy (left 1/2001) OTE, Greece SWISSCOM, Switzerland Telecom Austria, Austria VIAG Interkom (O2), Germany

6 Maximilian Frey Concepts for Testing UMTS Network Integration Testing –End-to-end tests: tests at layer 3: Call Control, Session Management, IP –Customer view: application tests, use channel tests –Service tests: IP, application tests Core Network Testing –ISUP/INAP/CAP tests –Service tests Testing –Use of TTCN-2: Converting to TTCN-3 planned –Use of PCOs for active testing at the user interfaces –Use of POs for passive testing at the core-network interfaces –Using different test architectures in the same test case

13 Maximilian Frey INAP/CAP PCO Use as PO and PCO at the same time –the standard PCO with TCAP-Primitives can not be used –a PCO on top of MTP-3 is used Not the complete SCCP and TCAP message is specified in the ATS -SCCP: cdpa and cgpa as well as the protocol class -TCAP:Message Type, Component Portion, Dialogue Portion, Dialogue Id

14 Maximilian Frey State of the Project TC for CS- and PS-services implemented Only API for application scripting on top of IP ATS completed for CS and PS services including SS, SMS and different application profiles Use channel tests and core network tests are completed Dynamic validation not possible, because of lack of a testsystem Project will be finished in may

15 Maximilian Frey ETSI-Workitems WI: DTS/SPAN : Network Integration Testing between GSM Phase 2+, ISDN and PSTN; Part1 TSS&TP/ Part2: ATS and PIXIT WI: DTS/SPAN : Network Integration Testing between UMTS, ISDN and PSTN; Part1 TSS&TP/ Part2: ATS and PIXIT WI: DTS/SPAN : Network Integration Testing between GPRS, and IP networks; Part1 TSS&TP/ Part2: ATS and PIXIT WI: DTS/SPAN : Network Integration Testing between IN, PLMN and ISDN; Part1 TSS&TP/ Part2: ATS and PIXIT Open point: Liaison with SGM

16 Maximilian Frey Conclusions TSS & TP and ATS for Network Integration Testing of –UMTS –GSM/GPRS –PSTN –ISDN –IP Testing at Layer3 –Testing at the appropriate interface for Network End-to-End Tests –Testcases for Core Network-Access Network interface as well as for Um Core Network Interfaces ISUP/IN: –Use of PO or PCO –different architectures in one testcase: Use of PO or PCO A contribution to ETSI Workitem for UMTS Testing Methodology??
