A method for operating a terminal in a mobile network arrangement of mobile network nodes, network node of a cellular network and terminal

The invention relates to a method for operating a terminal (e.g., UE1.) In a mobile radio network (N1, N2) with the following steps: - attaching of the terminal (UE1) to a mobile network node (MR) of a radio interface to the mobile radio network (N1, N2) coupled to the mobile access network (ZN), - sending a connection message from the terminal (UE1) on the mobile network node (MR) to the mobile radio network (N1, N2), - registering in the mobile radio network (N1, N2), that the mobile network node (MR) is representative of the terminal (UE1), the mobility control over the mobile radio network (N1, N2) takes over, and - performing the mobility control for the registered terminal (UE1) over the mobile radio network (N1, N2) by the mobile network node (MR). Moreover, the invention relates to an arrangement, a mobile network node (MR), a network node (ZN2) of a mobile radio network (N1, N2) and a terminal (UE1, UE2).
