The invention relates to a combined mobile radio communication system. This combined system comprises a first mobile radio communication system (R) with a first geographic coverage area and with first base and mobile stations (BSR; MSR) and allocated a first set of radio channels within a first frequency band for transmission from the first mobile stations (MSR) to the first base stations (BSR) and a second set of radio channels within a second frequency band for transmission from the first base stations (BSR) to the first mobile stations (MSR). Included is also a second mobile radio communication system (L) with a second geographic coverage area, which at least partially coincide with the first geographic coverage area, and with second base and mobile stations (BSL; MSL) and allocated a third set of radio channels within a third frequency band, which at least partially coincides with the first/second frequency band, but is different from the second/first frequency band, for transmission both from the second mobile station (MSL) to the second base stations (BSL) and vice versa. Means (10, 12) within the second geographic coverage area detect radio signals within the second/first frequency band and further means (BSC) estimate the disturbance risk from the second mobile radio communication system (L) at said first base stations (BSR) with the aid of the signal strength of the detected radio signals. |
