Abstract
A master node (MN) () controls the MN () to enable, for a radio terminal (), dual connectivity using a Master Cell Group (MCG) provided by the MN () and a Secondary Cell Group (SCG) provided by a secondary node (SN) (). The MN () sends to the SN () a first message related to a modification or release of a configuration or resource in the SN () regarding the dual connectivity. The first message explicitly or implicitly indicates that the modification or release is related to a failure of the MCG or recovery from the failure of the MCG. This, for example, allows the SN to distinguish a message regarding modification or release of an SN configuration (or resource) sent from an MN to the SN for recovery from an MCG failure from other messages.
