a memory that stores, for a network function of the second mobile communication network, an indication comprising an indication that the network function is a network function that takes over serving mobile terminals served by a network function of a first mobile communication network included in one of one or more other mobile communication networks;
a receiver that receives, from the first mobile communication network, a request for selecting a network function to take over serving a mobile terminal served by the network function of the first mobile communication network; and
a selector that selects a network function stored in the memory, based on the request, for taking over serving the mobile terminal,
wherein the selector searches the memory for a network function that is indicated as being configured to take over serving the mobile terminals served by the first mobile communication network, and selects the network function found as the network function to take over serving the mobile terminal.
