Abstract
A mobile communication system provides different types of radio communications using a same mobile terminal service. One service area is provided by conventional base stations by which the mobile communication network is carried out, and another service area is provided by a fixed network terminal device, such as a cordless home phone connected in a public fixed communication network, and the mobile terminal device can be used in both service areas by switching over internal call circuit appropriately. On the other hand, a call directed to the mobile terminal device is suitably routed to the mobile terminal device in either of the service areas by a terminal device switching circuit in the mobile communication systems having a database on which location information of the mobile terminal device are registered.
