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

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

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

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
