Combined mobile radio communication system

Abstract

A combined mobile radio communication system comprises a first mobile radio communication system with a first geographic coverage area and with first base and mobile stations and allocated a first set of radio channels within a first frequency band for transmission from the first mobile stations to the first base stations and a second set of radio channels within a second frequency band for transmission from the first base stations to the first mobile stations. Included is also a second mobile radio communication system with a second geographic coverage area, which at least partially coincide with the first geographic coverage area, and with second base and mobile stations and allocated a third set of radio channels within a third frequency band, which at least partially coincides with the first frequency band, but is different from the second frequency band, for transmission both from the second mobile station to the second base stations and vice versa. A detector within the second geographic coverage area detects radio signals within the second frequency band and an estimator estimates the disturbance risk from the second mobile radio communication system at said first base stations with the aid of the signal strengths of the detected radio signals.
