Claim 0:
1. A method performed by a master node (MN), the method comprising:
transmitting, to a first Secondary Node (SN), a first base station control message, wherein the first base station control message includes first information in response to a preparation procedure for a first reconfiguration procedure being performed;
receiving, from the first SN, a second base station control message, wherein the second base station control message includes second information, and wherein the second information includes a cell global identifier of a specific cell for the first reconfiguration procedure;
transmitting, to a terminal, a first Long Term Evolution (LTE) downlink (DL) message, wherein the first LTE DL message includes a first identifier and one or more CondReconfigToAddMod, and wherein each of the one or more CondReconfigToAddMod includes an execution condition, a second identifier, and a New Radio (NR) DL message;
receiving, from the terminal, a first LTE uplink (UL) message, wherein the first LTE UL message includes the first identifier, and wherein the first identifier corresponds to the first LTE DL message;
receiving, from the terminal, a second LTE UL message, wherein the second LTE UL message includes a second identifier, and wherein the second identifier corresponds to the NR DL message;
transmitting, to a second SN, a third base station control message, wherein the third base station control message includes tunnel information for data forwarding; and
transmitting, to the first SN, a fourth base station control message, wherein the fourth base station message includes a NR UL message received from the terminal.
