Systems and techniques for improved mobility robustness optimization. A user device experiencing a radio link failure sends a radio link failure report upon successfully connecting to a cell. The radio link failure report is routed to an appropriate cell, such as the cell where the radio link failure occurred. Radio conditions measurement information appearing in the radio link failure report is compared against each possible applicable threshold that might have been used by the user device, and a failure event is recorded for each comparison that indicates a failure, such as a radio link failure or handover failure. The failure event information is forwarded to suitable network elements for analysis and improvement of mobility robustness optimization operations.
