Key Performance Indicators (KPIs) can vary widely, depending on what information is available from the equipment and on what is important to the operator. Nonetheless, they tend to fall into a few broad categories.

For LTE performance, the most commonly used KPIs are:

  1. Accessibility: The ability of a subscriber to get access to the network to establish a default bearer. Setup failures track how often a user tried to set up a session, but was unable to do so, while paging success indicates how often a subscriber in the area could be reached.
  2. Retainability: The ability of a subscriber involved in a session to stay up and running. The intent of the retainability metric is to track the number of abnormal E-RAB releases. These abnormal releases may be eNodeB generated or MME generated.
  3. Integrity: This metric tracks the network’s ability to deliver IP packets to & from the end user. Integrity can be subdivided into two quality-based KPIs, which include throughput and latency.
  4. Mobility: It simply measures the success rate of the handover preparation and execution phases. This includes intra-frequency handover, and inter-RAT handover.
  5. Availability: It is a KPI that measures the percentage of time that a cell can provide service to end users. Typically, both scheduled and unscheduled outages are included in the derivation of the metric.
