NSA is a suite of fully-automated software applications for troubleshooting and optimization of mobile networks and services. NSA allows multiple users to trace subscribers’ calls both in real time and offline as they travel across the network over multiple interfaces and over several network elements, such as control plane and user plane analysis. Identification of network problems and service quality degradation, from the symptom down to the root cause, becomes tremendously fast and easy. Its capabilities and benefits can be realized across UMTS (including HSPA), WiMAX and 2.5G/2G (Core, GERAN) networks. It is designed to support the K18 and K15 platforms. As a result, time required to obtain and analyze data from across all wireless mobile networks is greatly reduced, and carriers can realize improved network efficiency and effective optimization of infrastructure.
