Disclosed herein is related to dual connectivity configuration, that discloses methods and systems for managing a handover, which may include managing throughput loss occurring before/after/during handovers in a dual connectivity configuration. One solution performed before handover includes managing throughput loss by temporarily boosting Buffer Status Report (BSR) of a stack not undergoing handover and transmitting all data packets using the Uplink resource grant received for the boosted BSR. Another solution performed after handover includes determining split ratio before handover itself based on nature and bandwidth information of target cell, and applying it after the handover, to mitigate throughput loss that occurs after handover. Another solution performed during handover is a combination of first solution of boosting BSR and second solution of determining split ratio. Another solution enables prediction of split ratio of potential target cells for an estimated handover using an artificial intelligence model.
