Methods and Apparatus for Radio Link Failure Reporting

摘要

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.

1. An apparatus comprising:
at least one processor; memory storing a program of instructions; wherein the memory storing the program of instructions is configured to, with the at least one processor, configure the apparatus to at least: examine one or more measurements of radio conditions experienced by a user device operating in a wireless communication network; compare each of the one or more measurements of radio conditions against every handover threshold applicable to that measurement, that could have been the handover threshold configured for use at the user device at the time of the measurement; and record a failure event for each comparison that indicates that a failure could have occurred.
