  • 1. 1 Delivering a “Test Once, Use Anywhere” Certification Scheme for LTE Devices LTE World Summit, Amsterdam, 18 May 2010 Adriana Nugter GCF Operations Manager Unrestricted – Non Confidential Information This is document is subject to copyright protection
  • 2. ©GCF 2010 2 Global Certification Forum – Why? GCF Certification = tested once, accepted by all • The industry’s de-facto certification scheme Testing cost – Includes conformance, interoperability and field testing • Delivers tangible value to all industry stakeholders – Increases assurance that terminals will perform correctly on networks – Saves costs on operators’ internal testing & field trials • One operator quotes costs of €50k-€200k per handset Testing time – Enables manufacturers to offer handsets to mulitple markets so improving economies of scale • Mature, stable regime but capable of evolving GSM GPRS 3G HSPA LTE
  • 3. ©GCF 2010 3 How does GCF work? • Definition – Process initiated by a formal proposal from member(s) • confirms real market need – Step 1: Industry (3GPP, OMA etc) develops test specifications – Step 2: GCF selects and prioritises tests to be executed – Step 3: Test industry develops the test platforms/test tools and implements the test cases – Step 4: GCF validates test cases (via test houses) • Implementation – Manufacturers perform agreed tests and certify through a GCF Declaration Keywords • PRIORITISATION, VALIDATION AND CERTIFICATION GCF focuses the efforts of operators, manufacturers and members of the test industry who are committed to global inter-operability Above reflects GCF process for conformance testing; a similar process exists for field trials
  • 4. ©GCF 2010 4 Membership structure for 2010 • Manufacturer Members (~50) • Observer Members (~70) • Operator Members – Full & Associate (>100) – Strong commitments from operators representing key markets: AT&T, China Mobile, Jasper Wireless, NTT DOCOMO, Orange, SFR, Telecom Italia, Telefonica, TeliaSonera, Verizon Communications, Vodafone
  • 5. ©GCF 2010 5 Important market trends • Mobile broadband becoming a native capability in: – Laptops/Netbooks/Smartbooks/Tablets – E-Readers – M2M/industrial/commercial devices – Connected consumer devices • Mobile broadband increasingly being integrated on device motherboards Certification is highly applicable to all 3GPP-connected devices • In 2009, 20% of devices certified through GCF were NOT “traditional” handsets Handsets 297 80% Data Connectivity Products 57 15% • USB modem • Data card • Mobile gateway / hotspot Embedded platforms / products 20 5% • Embedded modules • Netbook / Notebook PCs Total Devices Certified in 2009 374 100%
  • 6. ©GCF 2010 6 Future certification frameworks Key objective for 2010 • Provide framework for certification of all devices with embedded 3GPP connectivity – Actively reviewing certification issues for different classes of “non- traditional” devices in order to streamline processes – 1st deliverable: rationalised laptop certification process – Developing relationships with automotive, ticket & metering and health sectors Though the certification of 3GPP-connected devices, GCF can help operators and manufacturers develop new markets
  • 7. ©GCF 2010 7 Performance Data Packages • Conceived as optional complement to GCF Certification • Allows manufacturers to provide qualitative data in response to operator needs – on agreed performance criteria – using standardised methodology • Battery life measurement & Acoustics now in place – available for use by operators and manufacturers • Future metrics will be driven by operator demand
  • 8. ©GCF 2010 8 LTE device certification – GCF targets • Certification of LTE devices to be available from Q4 2010 – To include Conformance, Interoperability & Field Testing – Target consistent with general NGMN requirement • Initial work priorities – requested by GCF members & agreed collectively – 3x FDD bands – 2x TDD bands • 13 / 700 MHz (USA) • 38 / 2570-2620 MHz (China) • 1 / 2100 MHz (Japan) • 40 / 2300-2400 MHz (China) • 7 / 2600 MHz (Europe) • Flexibility – Scheme deliberately structured to accommodate proliferation of LTE bands – as driven by the needs of markets worldwide • FDD Band 3 / 1800 MHz added in April 2010. Availability expected in 2010 • FDD band 20 / 800 MHz (European digital dividend) to be fast-tracked once standardised for mobile by 3GPP GCF ready to transform members’ aspirations into reality
  • 9. ©GCF 2010 9 LTE Work Item Structure • Work items defined for: – RF – E-UTRA for both FDD and TDD – EPC • 4 priority groups identified for signalling tests – First Certifications will be based on priority groups 1 & 2 lists are currently 99% stable • 2 priority groups identified for RF tests • Individual work items covering each selected E-UTRA band – organised so that delays in any one band will not delay other bands • DOCOMO and China Mobile are heading up the FDD & TDD effort respectively • Excellent support is being provided by rapporteurs from Ericsson, Samsung, NEC, Nokia, Qualcomm, Motorola & TeliaSonera.
  • 10. ©GCF 2010 10 LTE Certification: Working Assumptions • Stable core specifications from 3GPP • Readiness of test specifications (mainly from 3GPP RAN5) • Availability of LTE Reference Terminals for test verification • Adequate investment by test industry in development of test implementations and platforms – LTE test platforms have been presented to GCF by: Agilent, Anite, Anritsu, AT-4 Wireless, Cetecom, Innowireless, Rohde & Schwarz, Setcom Wireless Products, w2bi • Ongoing feedback on operators’ expectations in terms of service/feature requirements and timelines – Apart from “first movers”, significant wave of commercial LTE networks & devices anticipated towards end 2010 Assumptions are under continuous review to ensure effort matches reality
  • 11. ©GCF 2010 11 LTE Conformance Testing - Status • Around 210 Protocol and 90 RF test cases needed for early certification – 9 RF test cases validated Momentum building – 97 protocol test cases validated – Further validations expected at July & October meetings – USIM / LTE interworking test cases recently added • GCF moved baseline to Dec 09 to reflect updates to Rel 8 related to SMS and Security – No impact for LTE-only networks – Accommodates SMS over LTE and security of WCDMA LTE handover – Taking flexible approach to early validation work (using pre-Dec 09 devices) to avoid obstructing validation process – Baseline change now endorsed by 3GPP RAN5 (responsible for TC specifications) • NB: ongoing close co-operation between GCF and RAN5 • Band-independent approach employed – Facilitated rapid response to changing needs of specific markets – RAN5 is expanding test specs in response to GCF requests
  • 12. ©GCF 2010 12 Status of TC validations after April CAG meeting • FDD Band 1 (Japan): RF: ~15% validated RRM: awaiting start of RRM validations Protocol: awaiting start of Band 1 protocol validations • FDD Band 7 (Europe): RF: ~13% validated RRM: awaiting start of RRM validations Protocol: ~48% validated • FDD Band 13 (USA): RF: awaiting start of Band 13 RF validations RRM: awaiting start of RRM validations Protocol: ~23% validated • Rate of validations is accelerating –RF validations accepted from Anritsu, Rohde & Schwarz –Protocol validations accepted from Anite, Innowireless, Rohde & Schwarz • TDD Bands 38 & 40 (China) & FDD Band 3 (Europe): TC validations expected from July mtg onwards Certification can start when 80% of test cases in each area are validated
