Presents 2005 IMTC Forum

1. Presents 2005 IMTC Forum

2. The Global Certification Forumincorporating aspects of Video Telephony Testing and Liaison with the IMTC 3G 324M WG Presented by Phil Brown NTT DoCoMo

3. What is the GCF? • The GCF is the Global Certification Forum • Voluntary scheme for MS/UE certification • Aims to reduce interoperability problems • Consensus driven organisation • Members: • Operators – 147 companies • UE Manufacturers – 43 companies • Observer members: • Test industry – 67 companies • Chairmanship is alternated between the operators and Manufacturers on an annual basis • Current Chair provided by Nokia • Current Vice Chair provided by Vodafone Europe • Change-over in Jan 06 IMTC Forum – May 2005 – Eibsee, Germany

4. What does the GCF provide? • Common UE certification scheme based on: • Agreed set of conformance tests • Agreed set of field tests/ IOT • Experience of typical interoperability issues • Therefore increased level of confidence in the basis functionality and inter-working of UEs on different mobile networks • Can be applied to UEs with: • GSM • GPRS/EGPRS • WCDMA Dual Mode & Single Mode • Scheme based on self declaration basis IMTC Forum – May 2005 – Eibsee, Germany

5. Certification Coverage • Typically the certification/test coverage will include basic functionality such as: • RF behaviour • Signalling protocols • Audio and USIM interfaces • Currently R99 for WCDMA but still evolving • New functionality to be covered/being covered: • MMS • HSDPA • A-GPS • IMPS 1.1 IMTC Forum – May 2005 – Eibsee, Germany

6. Benefits of GCF to Members • Single benchmarking scheme • Manufacturers only need to concentrate on one set of tests for GCF operator requirements • Test selection is a joint effort by all members • Certification can be used as a condition of purchase by operators (plus any other specific requirements) • Integrated test development process with the test industry to deliver requirements • Scheme adaptable to changing requirements and new UE functionalities • New tests introduced via Work Item oriented method • Selection of tests reviewed and can be removed • Modular certification approach being considered to reduce test time (methodology still being developed) IMTC Forum – May 2005 – Eibsee, Germany

7. Global Relationships • Majority of activity comes from Eurocentric members but an increasing amount of interest is coming from Asia • Close relationship with Standardisation bodies, for instance: • 3GPP TSG RAN WG5 (RAN5) for conformance test development (RF & signalling) • 3GPP TSG CT WG6 (CT6) USIM testing • Open Mobile Alliance • Developing joint strategy with the PCS Type Certification Review Board (PTCRB) • US equivalent certification scheme • Adopting common procedures • Test once certify twice principle • Looking to develop a closer relationship with the IMTC • Adoption of IMTC specifications • Create mutually beneficial situation • First contact via the 3G 324M Working Group IMTC Forum – May 2005 – Eibsee, Germany

8. GCF Structure IMTC Forum – May 2005 – Eibsee, Germany

9. Meeting Schedule • Steering Group • Quarterly • Duration: 2 days • Preceded by separate operator & Manufacturer one day meetings • GCF Management Group • Quarterly • Duration: 1 day • Agreement Groups • Quarterly • CAG duration 2 days • AEAG duration 1.5 days • Ad hocs/Workshops • As required basis • Normally no longer than 1 day IMTC Forum – May 2005 – Eibsee, Germany

10. Resourcing • Annual budget resourced: • Equally between operators and manufacturers • Contribution from observer members to assist with meeting costs • Pays for (in general terms): • Secretariat • Meeting expenses • IT support including web site • Third party contracts usually very short term IMTC Forum – May 2005 – Eibsee, Germany

11. Testing Regimes • Various options for UE manufacturers: • In house testing using quality certified facilities • Third party test houses • Field trials conducted on up to 5 Field Trials Qualified (FTQ) mobile networks • Requires details of operators’ networks • Requires some cooperation with hosting operator • Typically 10 man days per network used • Field trials tend to be late in the UE’s development (within 3 months of commercial launch) • Declarations sent to the secretariat and made available to the operator members on the GCF web site IMTC Forum – May 2005 – Eibsee, Germany

12. Standards Development Organisations • References made to recognised standards development organisations (SDO) for core and test specifications such as: • 3GPP • OMA • IMTC • Condition that standards are publicly available • Note that GCF does not develop standards but only uses them as a reference IMTC Forum – May 2005 – Eibsee, Germany

13. Certification Entry Criteria (CEC) • Each work item has a pre-determined criteria such that: • When the quantity of tests within the WI reaches a threshold, the CEC conditions are considered met • Normally this is 80% of the tests • Can also be dependent on previous work items • Commercial test equipment must be available at this time • In general terms, any UE being certified must use the relevant tests in the work item thereafter • UEs not supporting certain functionalities are not required to pass non-relevant tests • The process is subject to the 110 day period in order that manufacturers can obtain the necessary equipment to conduct the additional tests IMTC Forum – May 2005 – Eibsee, Germany

14. Outline Process…1 • Requirements for test coverage for existing or new UE functionalities proposed via a work item • Normally raised at the AG level and should include: • Rapporteur & supporting companies (minimum of four) • Business justification • Technical specifications to be used • Quantity, nature and duration of testing • Pre-conditions and target completion dates • Needs Steering Group approval (in principle at least) to allow the work to start in earnest • GCF work plan updated accordingly IMTC Forum – May 2005 – Eibsee, Germany

15. Outline Process…2 • Once the SG ‘green light’ is given: • Off line discussions or ad hocs • Selection of test requirements • Selection of test specifications • Appropriate action by the SDOs • At Agreement Group Meetings: • Technical queries answered • Test platforms presented for approved • Test validation reports presented for approval • Way ahead agreed or further guidance provided IMTC Forum – May 2005 – Eibsee, Germany

16. Validation Tracking • Validated tests recorded onto an online certification criteria (CC) database • Status of individual test cases can be changed dynamically based on 5 and 10 day rule notification system • Most changes occur during the agreement group meetings when validation reports are accepted • Manufacturers must certify using the most recent version of the database subject to a 110 day overlap rule IMTC Forum – May 2005 – Eibsee, Germany

17. CS Video Telephony • The GCF SG has approved in principle WI-018 • Proposed by NTT DoCoMo • Introduces CS VT tests into the certification scheme • Currently 17 supporting companies • Technical work undertaken by supporting companies in an ad hoc meeting including members of the IMTC 3G 324M working group • Test selection and test methodology to be defined but common issues to be tackled have been agreed • The completed work item needs final approval at the next Steering Group meeting in Jun 05 • All the necessary CRs to PRDs need to be in place by the next Agreement Group meeting to enable the CEC to be met • Process is simplified as work item only intended to cover pure client to client testing (IOT) not conformance testing at this stage IMTC Forum – May 2005 – Eibsee, Germany

18. CS Video Telephony Summary • Status: • First ad hoc was held 13 Apr 05 • Issues selected for review by IMTC 3G 324M WG • Next ad hoc scheduled for 24 May 05 • Final approval of WI planned for SG#23 (Jun 05) • Target completion date after AEAG#5 in Jul 05 • Initially: • To start with IOT (client to client) only • Assess the potential coverage and/or effectiveness of the IMTC solution or whatever is in place • Longer Term: • consider the way forward which may be a proposal to launch a follow up WI which will be more conformance test based to cover any perceived outstanding issues (although this aspect is still under discussion) IMTC Forum – May 2005 – Eibsee, Germany

19. Looking to the Future • Application enabler testing becoming more critical to keep up with increased UE functionality • Rationalisation of the CC content will be needed to ensure the time spent in testing does not dis-advantage members due to: • Delays and time to market • Increased testing costs • Looking to integrate with more organisations around the world to offer a more global service without un-necessary duplication of effort because: • Customers expect interoperability everywhere • Testing is expensive in time and cost therefore a coordinated approach will reduce the overheads for operators and manufacturers • UEs functionality is increasing as do the risks of interoperability • Number of mobile networks with different access technologies on different release of standards is increasing, creating a moving target for UE manufacturers IMTC Forum – May 2005 – Eibsee, Germany
