  • Method of controlling call routing and a communication terminal
    Patent number: 6321096
    Abstract: A communication terminal (MT) is equipped with a first communication unit (KOM1) for communicating with radio network base stations (DECTS) via a first radio interface (RI1), and with a second communication unit (KOM2) for communicating with a mobile radio network (MN) via a second radio interface (RI2). The terminal (MT) determines whether it has moved into the range covered by the radio network base stations. If it has moved into the range (RADECT) covered by a selected radio network base station (DECTS), it initiates a switch-over of the network-side routing of connection requests which are directed to the terminal (MT), and routes them via the selected radio network base station (DECTS). The initiation of the switch-over takes place by signalling the mobile radio network (MN).
