In a mobile radio system, which comprises densely positioned base stations working with a short range between the affected base stations and mobile units, repeating functions are carried out by means of a simplified variant of a base station. This simplified variant of a base station is positioned between the ordinary base station and the mobile unit, which simplified variant of a base station receives a respective message and forwards the message to the affected mobile unit.
