Abstract
Systems and methods for user equipment handover preparation efficiency optimization are provided. In some embodiments, a base station may learn from prior UE handover operation attempts which neighboring base stations are operating in a barred access mode, and apply that information to subsequent handover operation attempts for other UE. In some embodiments, a handover preparation optimizer function maintains barred neighbor data that indicates when a UE handover operation attempt fails due to the target base station operating in a barred access mode. The source base station may then reference that barred neighbor data prior to sending subsequent handover request messages. In some embodiments, the handover preparation optimizer function may periodically refresh the barred neighbor data, for example by removing entries for target base stations listed in the barred neighbor data after a configurable period of time.
