  1. Application Key Performance Indicatorsfor Mobile WiMAX Raj JainWashington University in Saint Louisjain@cse.wustl.edu Presentation to WiMAX Forum Application Working Group Meeting, Orlando, FL, February 4-9, 2009 These slides are also available at:http://www.cse.wustl.edu/~jain/wimax/kpi.htm

  2. Overview • What is a Key Performance Indicator • KPIs for Telecom Applications • Steps in KPI Study

  3. What is a Key Performance Indicator • Gives a good indication of performance • Commonly used in business • Metrics to define and measure business goals • Examples: • GNP (Gross National Product) • ARPU (Average Revenue Per User) • Dow Jones Index

  4. KPIs for Telecom Applications • Connection Establishment Success Rate • Connection Drop Rate • Handover Success Rate • Throughput • Block Error Rate Ref: UTRAN and GERAN KPI (3GPP TR32.814, March 2007)

  5. 3GPP KPIs Categories • Retainability: Call drop rate • Availability: Cell unavailability • Integrity: Block error rate

  6. KPIs – Complete Set

  7. Selecting KPIs • Include: • Performance Time, Rate, Resource • Integrity: Error rate, probability • Availability: Time to failure and duration • Consider including: • Mean and variance • Individual and Global • Selection Criteria: • Low-variability • Non-redundancy • Completeness

  8. Steps in KPI Study • Key Applications • For each application: • User perceived performance • Relationship to measurable quantities • Precise definition and formula for computation

  9. KPIs in 3 Planes • Data Plane: User throughput • Control Plane: Scheduling overhead • Management Plane: Faults Control Application Mgmt TCP/IP Data MAC PHY

  10. KPIs for All Parts of Networks • Mobile/stationary Subscriber • Base Stations • Base Station to Mobile Subscriber Link • Cell • Backbone network Uplink (UL) Backhaul Base Stations Downlink (DL) Mobile Station

  11. Summary • Application KPIs can be used by service providers to set their business goals • User level KPIs can also be used by major customers to compare services • Need to define KPIs that include key systems and subsystems and include operations and data transfer
