  1. 1. LSTI – Boosting LTE for Mobile Broadband Deployment Christian Kuhlins, Ericsson AB Remi Thomas, FT Orange Chairman LSTI IOT Activity Group Director of the LTE EPC Programme at France Telecom christian.kuhlins@ericsson.com remi.thomas@orange-ftgroup.com www.lstiforum.org
  2. 2. 42 Members Boosting The LTE/SAE Ecosystem 2007 2008 2009 2010
  3. 3. The Journey From Testing Prototypes To Testing Real Products Interoperability Testing IOT Interoperability Development EPC Testing - IODT EPC S1 S1 eNB eNB eNB Uu X2 Uu Standard compatible Standard compatible product prototypes platforms to reach the market
  4. 4. First LTE Devices And Networks Interoperating IOT Uu ”Vendor A to report: EPC successful test eNB S1 S1 eNB with two Vendor A Vendor A different Ue vendors B&C!” X2 Uu Ue Vendor B & C
  5. 5. Multi-Vendor Network Configurations Interoperating ”Vendor A ”Vendor A to report: to report: successful test successful test with another EPC with another eNB vendor B!” vendor B!” IOT S1 IOT X2 EPC EPC Vendor B eNB eNB eNB eNB Vendor A S1 S1 Vendor A Vendor A S1 S1 Vendor B X2 X2 Uu Uu
  6. 6. LTE/SAE - Becoming A Mature Technology For Mobile Broadband …to Commercial Rollout From Standardisation… Proof of Concept Proof of Concept completed IODT: Close to completion Interoperability IOT: First results for Air Interface and S1&X2 interface delivered Active Trials Friendly Customer Trials delivering first results
  7. 7. LSTI Friendly Customer Trials (FCT) Consolidated Test Methods For LTE • Common recommendations for set-up of Trial Networks • Common definition of Key Performance Indicators • Common generic procedures for Trial Configuration • 42 test specifications grouped in 13 testing domains • Set of methodologies according to NGMN Field Trial Requirements • LSTI FCT split in 2 Trial Phases: • Radio Access testing allowing non-commercial or simulated EPC solutions • Integration with EPC & E2E using fully “commercial” network platform
  8. 8. LSTI Trials started: 10 Operators perform LSTI Trials
  9. 9. Architecture Of A Typical Trial Network EPC MME HSS PCRF S1-MME Serving PDN Gateway Gateway S1-U Application Servers Fiber Video WEB FTP/UDP Streaming SGi UE Protocol eNB Performance OAM Analyzer traces Monitoring Mobile trace tool
  10. 10. 7 Operators Already Delivering Trial Results Test cases: • Latency • StateTransitions • Throughput • Cell Capacity / Cell Load
  11. 11. First Results Meet Expected Performance Levels Latency First LSTI FCT Trials U-Plane: Measured Round Trip Times (32Byte) demonstrate that LTE can deliver a very low latency experience; this enables PoC Results even the most demanding Trial Results applications such as online 0 5 10 15 20 25 30 ms Non-scheduled gaming. EPC Application Server eNB UE End – End ping Measured Round Trip Times
  12. 12. First Results Meet Expected Performance Levels Throughputs • The measured peak rates for FDD & TDD normalized to 20 MHz meet or exceed the NGMN Field Trial expectations of at least 100 Mbps for downlink & 30-50 Mbps on uplink. • The throughput depending on radio link quality (single UE testing) indicates a good alignment between 6 different trials.
  13. 13. Plans Are Defined For E2E Performance Testing • Both Radio Access testing and End to End testing phases are planned throughout 2010 for most of LSTI Operators. • On a test domain per test domain basis, the LSTI FCT group will analyse detailed results and elaborate an explicit message to the industry. • Performance levels and main relating testing conditions will then be displayed for sustaining the LTE-EPC ecosystem.
