Cell handover with minimum mobility interruption

A user equipment (UE) comprising:

• one or more non-transitory computer-readable media having computer-executable instructions for performing a handover procedure with minimum mobility interruption embodied thereon;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
• receive, at the UE, a reconfiguration message having an indicator for performing a dual-connectivity based (DC-based) handover procedure;
• and
• perform the DC-based handover procedure, wherein a packet data convergence protocol (PDCP) entity at the UE maintains different security keys to decipher PDCP packets received from at least one of a source base station and a target base station while the UE is transitioning from the source base station to the target base station, wherein a first security key is associated with the source base station and a second security key is associated with the target base station.
