1 A Firm Step of 3GPP for UE Conformance & Interoperability Shicheng Hu ETSI PTCC 22 May 2003
2 3GPP UE Conformance 3GPP W-CDMA User Equipment (mobiles) conformance test specifications are under high responsibility of 3GPP TSG T1 T1 specified protocol and signalling tests to ensure the UE interoperability TS 34.108, Common test conditions TS 34.123 – 1, Prose test specification TS 34.123 – 2, PICS & Applicability Statement TS 34.123 – 3, TTCN Test Specification 3GPP recognise that the UE interoperability is one of key issues to ensure 3G success Standardised rigorous conformance is the decisive way for UE interoperability 3GPP with the marketing partners funded a task force (ETSI MCC task 160) to develop TS 34.123-3. 3GPP management commitment to this project in a long term
3 3GPP UE ATS 3GPP UE ATS Project Started June 2000 3 Mio € fund till 2003 6- 10 experts from ARIB, CWTS, ETSI and T1 members ETSI provide leadership and management Task force works closely with 3GPP TSG-T1 and test industry ATS written in TTCN-2+ Test procedure, method and contents follow the prose 800 TC in 8 ATS over Uu radio interface All ATS share the common modular test library Access stratum test Non access stratum test Radio access bearer test 3G – 2G test
4 ATS Approval, Prioritisation & Maintenance Quality criteria for approval TC approval one-by-one TC run on two different tester platforms against commercial UE Test log files and parameter setting published 400 TC prioritised in 4 test packages A test package contains 100 TC P1 completed TC deployment package-wise Whole deployment in 2004 4 Maintenances per year Delivery every two weeks Three streams Move baseline Once per year Synchronised moving For all 3G vendors Backwards compatible
5 TTCN-2 / TTCN 3 TTCN-3 is the language for 3GPP further test specs Rel-5 and above, e.g. SIP test Mobile Application Enabler test 3GPP test industry invested largely in TTCN-2 Further demands on TTCN-2 tools with deployment of approved TC No plan to convert 3GPP ATS from TTCN-2 to TTCN-3 Tool makers should pay attention to TTCN-2 tool maintenance
