  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
