Core Network Signaling and Session Management KPIs

This dataset provides granular KPIs for core mobile network signaling and session management, covering MME, AMF, and SMF functions. It includes attach rates, session establishment success, interface load, and GTP tunnel metrics, enabling operators to monitor, optimize, and troubleshoot network performance across regions and time periods.

Behind this dataset

Same schema. As many rows as you need.

These 250 rows came out of a blueprint — 23 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.

Rules it was built with
  • Network element ID: MME (4G) or AMF (5G) instance identifier
  • Attach/registration success rate percentage and failure causes
  • TAU (Tracking Area Update) or RAU (Routing Area Update) success rate
  • PDN connection (4G) or PDU session (5G) establishment success
  • Average number of attached/registered subscribers per NE
  • S1/N2 interface load: messages per second and bandwidth utilization
  • GTP (GPRS Tunneling Protocol) tunnel setup time in milliseconds
  • Paging success rate and paging response time
