Title:
マスターノード、セカンダリノード、及びこれらの方法
Document Type and Number:
Japanese Patent JP7392722
Kind Code:
B2
Abstract:
A master node (MN) (1) controls the MN (1) to enable, for a radio terminal (3), dual connectivity using a Master Cell Group (MCG) provided by the MN (1) and a Secondary Cell Group (SCG) provided by a secondary node (SN) (2). The MN (1) sends to the SN (2) a first message related to a modification or release of a configuration or resource in the SN (2) 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.
