Abstract
A radio communication system includes a first base station that manages a first cell (), a second base station () that manages a second cell (), and a radio terminal (). The radio terminal () supports dual connectivity involving a bearer split in which a first network bearer between the radio terminal () and a core network () is split over the first base station () and the second base station (). The first base station () receives, from the second base station (), bearer split status information about communication of the first network bearer in the second base station (), and performs control of an access stratum related to the first network bearer. It is thus possible to contribute, for example, to an improvement in control of an access stratum when dual connectivity involving a bearer split is performed.
