5G networks and network fragmentation are designed to support enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and mobile internet of things (mloT) services. Some services have ultra-low latency, high data capacity, and stringent reliability requirements, where failures or performance issues in the network may cause the service to fail. Thus, the collection of real-time performance data or performance measurements may be used by analysis applications (e.g., network optimization, self-organizing networks (SON), etc.) to detect potential problems ahead of time and take appropriate action to prevent or mitigate these problems. In addition, the performance data may be able to be consumed by multiple analytics applications with specific purposes.
