Abstract

Handover (HO) statistics and handover issue events which are due to non-mobility causes are not included in the statistics fed into mobility robustness optimization (MRO). The non-mobility causes may include, e.g., load balancing, retracting users to prepare for cell maintenance or restart/reconfiguration and cell outage including compensation means. Radio link failure (RLF), handover failure (HOF), and handover oscillations (HOosc) that are due to non-mobility cause are excluded from the statistics upon which mobility robustness optimization is based. Non-mobility causes are also differentiated from mobility causes when reporting key performance indicators to an operator.
