1. A method, comprising:
identifying a user equipment (UE) performing a handover from a first node to a second node;
applying a first mobility robustness optimization (MRO) function to identify a target parameter corresponding to the handover, wherein the target parameter includes a message exchange timing corresponding to messages exchanged between the UE and the second node to execute the handover;
monitoring one or more connection measurements and one or more radio link failure reports corresponding to the handover;
identifying the handover as failing to meet the target parameter based on an analysis of the one or more connection measurements or the one or more radio link failure reports;
in response to the identifying, disabling a second MRO function corresponding to the second node to enable modification of handover parameters at the second node; and
in response to the disabling, modifying the target parameter to facilitate the handover to the second node by modifying the message exchange timing at the second node to execute the handover.
