and accurately identify and diagnose service problems.
Maintaining focus Given LTE’s complexity and high traffic volume, operators can maxi- mize the efficiency of network as- surance and minimize operating expenses by focusing on the right KPIs and the essential data.
Hundreds of KPIs will over-
whelm operations teams, so carri- ers should look to monitor just the service-focused KPIs that are important to their business. Composite KPIs can
reduce the number of KPIs without losing detail while providing flexibility about what sequence of messages a KPI relates to. LTE, therefore, will deliver much to op-
LTE on the move: an engineer’s toolkit Te new generation of service assurance
solutions enables mobile operators to track an extensive set of KPIs, including network performance and data service quality, to man- age network infrastructure and deliver an outstanding customer experience. Easily con- figured KPIs and thresholds pinpoint critical
service and network problems. Tat means complex network-wide service information is automatically interpreted and correlated. Tis information is then presented in a simplified way with guided analysis to assist in problem resolution. Tese capabilities empower instal- lation and maintenance teams to effectively
erators, but not without increasing the com- plexity of monitoring and troubleshooting. Trials will be vital for ironing out any of the problems that inevitably occur with large-scale deployments and the latest generation of test equipment will play a major role in ensuring this process runs smoothly. With the right test and measurement strat-
egy in place, operators can be sure that their LTE deployments will meet with success and deliver on the promise of the new standard.
