The race is on. Mobile service providers around the world are competing to execute successful 4G/LTE trials, deploy networks quickly, and maintain a high quality of service for subscribers. But several factors make the migration from 4G/LTE trials a complex process. Advanced testing tools for monitoring network performance and troubleshooting service issues can help service providers to launch LTE networks more quickly and reliably and ensure the quality of service. By understanding key performance indicators of their network, carriers can enhance their customer service and minimize capital expenditures and operating costs.
Service providers are increasingly transitioning from 3G to 4G/LTE networks:
• Analysts estimate that LTE will be commercially available in over 54 countries by 2015. (Research and Markets study)
• Global LTE subscriber levels are projected to reach 428 million by 2016. (Juniper Research study)
Factors that make LTE network trials and deployments complex include:
• First adopters tend to have exacting quality of service demands, which require more troubleshooting and issue management.
• There are more test points requiring monitoring, and huge volumes of data need to be correlated across the network.
• More interfaces must be tapped, and the signaling that goes with service delivery is much more complex.
Service providers can help to ensure the quality of LTE services with advanced testing by:
• Tracking an extensive set of key performance indicators (KPIs), including network performance and data service quality, enables fast root-cause diagnosis to help resolve problems before they affect customers.
• Monitoring just the service-focused KPIs that are important to their business rather than hundreds of available KPIs that will overwhelm operations teams. They should be attentive to KPIs such as network functionality and data service quality to evaluate how to resolve service-affecting issues.
• Analyzing subscribers' networks and service interactions, correlating these transactions into a single context and tracing them from real time to several weeks in the past. Effective troubleshooting demands that this series of inter-related transactions be presented in a single end-to-end view of the complete LTE network. With this comprehensive view, an operations team can diagnose complex issues quickly and reliably.
