The solution gives operators an end-to-end view of mobile networks from individual subscribers, applications, devices and operating systems, network elements, cells and calls.
The analytics links the performance of applications and devices to network issues in real-time, effectively making every mobile device part of a network test bed. This enables operators to pin point potential causes of service degradation much more rapidly than they can today since they no longer need to consult a myriad of tools and correlate the data from them manually, Nokia said.
Further, the solution also offers engineering teams a proactive way to understand Over The Top (OTT) application impacts on the network and optimize opportunities.
The Real-Time Mobile Network Analytics solution integrates three network analytics tools: Nokia Wireless Network Guardian that provides engineering teams with analytics on applications, network and devices; Nokia Traffica that supports Network Operations Centers by linking application-level analytics to real-time troubleshooting and root-cause analysis in radio and core networks; and Nokia Network Performance Optimizer that provides deeper, call-level analytics
These tools are widely deployed by more than 200 operators, Nokia said.
The combination of tools, sources data directly from radio access and core networks with fewer tapping points than standard solutions. This reduces the need to expand interfaces for legacy network probes. It also offers open Application Programming Interfaces (APIs) that enable operators to use the collected data for their big data strategies.
Real-Time Mobile Network Analytics use-cases include IoT device and service insight, real time input for automated congestion/traffic management, identifying problems with OTT applications, providing real-time marketing insight, precise scaling of virtualized functions, and assuring high quality, interruption-free VoLTE.
Bhaskar Gorti, president of Nokia’s Applications and Analytics business group, said, “Currently, operators are forced to take important operational and engineering decisions based on disconnected sets of data from separate tools for radio, core and transport networks. This makes it very hard to perform network-wide engineering and optimization or identify if a problem originates in the network, device, device OS, radio link, cell core network, transport network or at some other point.”
The new approach introduced by Nokia helps meet the needs of modern-day operators by providing on-the-fly correlation of network-wide data and its analysis per application, per cell, per subscriber, per device and even per call. In the future we will extend this capability to support fixed networks and Wi-Fi, Gorti said.
