Abstract
Some of the present implementations provide a method for a user equipment (UE) for performing a handover procedure with minimum mobility interruption. The method receives, at the UE, a reconfiguration message that has an indicator for performing a dual-connectivity based (DC-based) handover procedure. The method then performs the DC-based handover procedure without reestablishing a packet data convergence protocol (PDCP) entity of the UE during the DC-based handover procedure. The PDCP entity maintains a plurality of security keys to decipher PDCP packets received from at least one of a source base station and a target base station during the handover procedure and while the UE is transitioning from the source base station to the target base station.
