Abstract
According to certain embodiments, disclosed is a method in a master node (MN) for minimizing user plane interruption delay. The method includes transmitting a handover request message to a secondary node (SN), receiving a handover request acknowledge message from the SN, and transmitting a reconfiguration instruction to a wireless device operating in dual connectivity with the MN and the SN. The reconfiguration instruction may include a new configuration wherein the SN is a target SN and an indication of a trigger used to switch to the new configuration.
