Abstract
A mobile radiotelephone system has a service station in radio contact with, and exchanges digital data with, at least one mobile broadcast station via intermediately connected switching units. For controlling data communication, the mobile broadcast station contains a microprocessor that accesses a first memory area in which is stored a control program to be processed by the microprocessor. In a second memory area, a loading control program is stored, which is accessed by the microprocessor in dependence on a loading command. During processing, data of a new control program are transmitted from the service station and are stored in a third memory area. After the storing of the new control program, for the controlling of the data communication between the service station and the broadcast station the new control program is processed in place of the previous control program. With the system, it becomes possible to modify or exchange the control program of a broadcast station.
