"As mobile and IP technologies converge, network management has become increasingly complex. This transformation poses significant operational challenges to mobile service providers. Traditional element and network management solutions do not allow service providers to keep pace with the volume and complexity of today’s mobile services. Manual processes are too slow and error prone. Reactive problem detection leads to longer outages and dissatisfied customers. And integration with existing systems and processes is expensive and time-consuming.Maintaining a high-quality subscriber experience within an LTE network requires operators to respond quickly to the dynamic nature of today’s mobile services and demands a new approach to network management.This application note details how advanced assurance and provisioning capabilities help wireless service providers to efficiently manage the complexities of LTE, from the RAN, across backhaul, to the packet core. Offering rapid provisioning and proactive troubleshooting that spans physical, routing, and service topologies, the Alcatel-Lucent 5620 Service Aware Manager (SAM) portfolio also provides fast and simple integration into existing operational environments and processes resulting in unmatched operational flexibility."
