    Abstract: A radio network (6) and a radio terminal (4) are configured to, when the radio terminal (4) is using a first cell (10) served by a first radio station (1) as a primary cell and a second cell (20) served by a second radio station (2) as a secondary cell, change the secondary cell form the second cell (20) to a third cell (30) while keeping communication status information regarding the radio terminal (4) on the second cell (20). 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.

It is thus, for example, possible to enable a communication service in the secondary cell to be continued even after the primary cell is changed when the primary cell is changed during execution of carrier aggregation (e.g., Inter-eNB CA) on a plurality of cells served by different radio stations.

    Abstract: The present disclosure relates to user equipment, access network node, and a method performed by them. A method performed by a user equipment (UE) for communicating via a non-terrestrial network is disclosed. The method comprises receive configuration information identifying preconfigured uplink resources for use by the UE in a Radio Resource Control (RRC) idle state; verify whether or not the configuration information is still valid; and determine whether to transmit data using the preconfigured uplink resources in accordance with the verifying.

    Abstract: A radio terminal can perform carrier aggregation using a first cell of a first radio station and a second cell of a second radio station. The first radio station performs, with the radio terminal, radio resource control for the first cell and the second cell in order to perform the carrier aggregation. Further, the first radio station transmits, to the second radio station, update information regarding an update to a configuration related to the radio resource control for the second cell. It is thus, for example, possible to prevent or reduce data transmission/reception failures which would otherwise occur while a configuration of radio parameters or the like is being changed by a radio terminal in carrier aggregation of a plurality of cells served by different radio stations.

    Abstract: A target RAN node (3) receives, from a core network (5), a message requesting a handover of a radio terminal (1) from a bearer-based network to a bearer-less network. This handover request message includes flow information related to at least one session to be established in the bearer-less network in order to transfer at least one packet flow of the radio terminal (1). The target RAN node (3) transmits, to the core network (5), a handover acknowledge response message containing a transparent container that includes a radio resource configuration information derived from the flow information and is to be forwarded to a source RAN node associated (2) through the core network (5). It is thus, for example, possible to appropriately configuring an AS layer of a target RAT in an inter-RAT handover.
