6 ©Omnitele Ltd Monitoring End-User QoS in… …pre-HSPA networks General user experience depends on two basic services Voice Services Data Services MOS, Success Rates, Drop Rates, Setup Time Throughput Generally available bitrates are not sufficient for data services. As throughput is the bottleneck, it becomes the measure to define the QoS

14 ©Omnitele Ltd pasive monitoring PMS/Network Counters CDR Crowdsourcing Monitoring Methodologies in mobile networks Vast amount of data 24/7 live monitoring Big picture of network utilisation trends Not available KPIs on End-User level Challenging implementation (Crowdsourcing) Average results do not tell much

15 ©Omnitele Ltd active monitoring Probes (static/mobile) Drive Testing Monitoring Methodologies in mobile networks Controlled environment Reproduces End-User cases Collects essential data for troubleshooting Amount of samples is limited Limited coverage information Expensive exercise (Drive Testing)

16 ©Omnitele Ltd Monitoring Methodologies best methodology? End-User Monitoring PMS/Network CountersProbes CDR Drive Testing Crowdsourcing a combination of all of them

17 ©Omnitele Ltd Monitoring Methodologies 1. What do I want to Monitor? 2. How my subscribers use the service? 3. What tools do I have available? 4. Correlate data from different sources set up a process
