摘要：A secondary base station () is configured to receive an SeNB addition requestmessage from a second master base station () while providing a radio terminal () with asecondary cell group (SCG) for DC in cooperation with a first master base station. TheSeNB addition request message indicates whether each of at least one bearer that has

already been configured in the secondary base station () for DC with the first master basestation () is to be kept at the secondary base station (). It is thus, for example, possible tocontribute to performing a procedure for changing a master base station in Dual

Connectivity (DC) by using existing inter-base station interface procedures and inter-basestation signaling messages.
