  • Method and apparatus for managing handovers in wireless communication system
    Patent number: 11617113
    Abstract: A method for controlling and managing handovers between base stations in adjoining cells in wireless communications enables a user equipment (UE) to report a bit error rate (BER) to a base station having current conduct of communication with the UE. If the BER is greater than a predetermined value, the base station having conduct further determines whether the UE satisfies a handover condition over a period of time and hands conduct over to another base station if the UE satisfies the handover condition for the period of time and if the other base station is not already operating at capacity. An apparatus for controlling and managing handovers is also disclosed.
