Japanese Patent JP7218835

B2

During a mobility procedure for moving a radio terminal (3) from a source cell (11) to one of candidate target cells (21-23), a target RAN node(2) transmits to the radio terminal (3), via a source RAN node (1), a first configuration common to the candidate target cells and a plurality of second configurations each associated with a respective one of the candidate target cells. The first configuration includes at least one configuration parameter for enabling the radio terminal (3) to access to one of the candidate target cells or to communicate therein. Each second configuration includes at least one configuration parameter for enabling the radio terminal (3) to access to the corresponding candidate target cell or to communicate therein. This contributes to, for example, reducing signaling overhead of an inter-RAN node interface (and an air interface) during various mobility procedures including handovers.
