Abstract
A radio network () and a radio terminal () are configured to, when the radio terminal () is using a first cell () served by a first radio station () as a primary cell and a second cell () served by a second radio station () as a secondary cell, change the secondary cell form the second cell () to a third cell () while keeping communication status information regarding the radio terminal () on the second cell (). It is thus, for example, possible to enable a communication service in the secondary cell to be continued after the secondary cell is changed when the radio terminal which is simultaneously using a plurality of cells served by different radio stations changes the secondary cell from a cell of one radio station to a cell of another radio station.
