  1. Testing & Monitoring Challenges of Next Generation Mobile Broadband LTE Network Chief Technology Officer Vikas Arora

  2. LTE Deployments Taking Off… 15 commercial networks were launched in 2010 ; 128 LTE commitments worldwide 10X increase in throughput per subscriber (2008-14) Mobile broadband services revenues to go to $186.7Bby 2014 (09-14 CAGR 25%) End user quality expectations going up!! >164.4M in 2014 Infonetics 2010

  3. Delivering and Managing Network & Service Quality:Key Pieces of the Puzzle Network (IMS, EPC, Ethernet, Optical) Device Applications & Services Data Centre Complex Device Deliver rapid trouble identification, segmentation, isolation and SLA assurance

  4. Example: LTE Network Monitoring & Troubleshooting • LTE Signaling • IMS sessions – RCS, Presence, Authentication, Call KPI’s • Session quality, Video quality, Content quality etc. Separated transfer paths for user plane and control plane

  5. Example: Ethernet Mobile Backhaul Turn-up through Operational Monitoring • EtherSAM Y.1564 for Turn-up Frame loss, delay, throughput, burstability, frame delay variation • Ethernet OAM standards (802.1ag, and Y.1731)

  6. In/Out-Service Troubleshoot • Locate problems • Find the cause of the problems quickly • Access to the details required • From mass data to the root cause Conformance/Load Testing • Test the functionality, interfaces • IMS Core performance, scalability • Interoperability MME/eNB, UEs • Test the load behavior before the real load 24/7 Monitoring Install/Burn-in/Troubleshoot • Physical layer characterization • Ethernet Testing & Troubleshooting • IP transmission tests • Connectivity to eNB • Delays/jitters in installation phases • End-user experience • SLA screening • Service usage, RCS, IMS monitoring • Network element/UE problems • Fraud detection, billing verifications LTE Testing & Service Assurance Lifecycle RCS EPC IMS VoIP Video Data Optical Ethernet

  7. Summary • LTE networks are gaining momentum, they require • A highly efficient turn-up testing, troubleshooting, performance monitoring & interoperability testing • In order to ensure performance, service delivery and quality of experience (QoE), complete visibility and access to key interfaces is essential
