NETWORK NODE, MOBILE TERMINAL, AND BASE STATION, AND METHOD CARRIED OUT USING THESE

摘要

According to the present invention, a first network node (121S) is configured to carry out mobility management and bearer management for a plurality of mobile terminals (111) that have been attached to a core network (120). Furthermore, the first network node (121S) is configured to perform, in accordance with a relocation instruction from a control node (142) which is connected to the core network (120), a relocation procedure for relocating mobility management and bearer management of the mobile terminals (111) to a second network node (121T) within the core network (120). Due to this, the present invention contributes, for example, to making it possible to relocate mobility management and bearer management of a plurality of mobile terminals between network nodes regardless of the movement of the mobile terminals.
