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

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

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

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

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
