摘要： A mobile communication system includes a base station and a mobility management device and controls a connection between a mobile terminal and a plurality of networks. The mobility management device is connected to the base station and manages mobility of the mobile terminal in a cell of the base station. The mobility management device acquires, from the mobile terminal, network identification information that identifies a first network when the mobile terminal connects to the base station. The base station receives, from the mobile terminal, quality information that indicates communication quality between a base station of the first network identified by the network identification information and the mobile terminal. The mobility management device instructs the mobile terminal, based on the quality information, to connect to the first network identified by the network identification information.
