Communication system for mobile terminals

摘要

The system (1) has a cellular mobile radio network with a hierarchical cell structure on devices (2, 3, 4) providing switching nodes for communication connections (9, 10) and forming cellular levels. The switching nodes of the devices (2, 3) on the cellular level of the radio network under utilization of a transmission medium are connected with the switching nodes of the device (4) on another cellular level of the radio network under utilization of another medium. A transition device connects the radio network with a public telephone network (6) via the switching nodes.
