A method for determining preset configurations for a set of first radio transmitters of a set of first radio cells being adjacent to a second radio cell with a respective second radio transmitter, wherein each first radio transmitter is assigned to a first radio cell, the preset configurations being designed to enable radio signals emitted from the first set of radio transmitters to serve as a substitute for radio signals emitted by the second radio transmitter within the original coverage area of the second radio transmitter once the second radio transmitter is in outage, the method comprising: - determining signal-data characterizing the coverage and capacity of the first radio cells by radio signals provided by the first and second radio transmitters; - determining signal-data characterizing the coverage and capacity of the second radio cell by radio signals provided by the first and second radio transmitters; - determining performance values characterizing the coverage and capacity of the first and second radio cells using the signal-data of radio signals provided by the first radio transmitters, - determining the signal emission and reception settings of the set of first radio transmitters; - determining a set of modified signal emission and reception settings for the set of first radio transmitters in order to enhance performance values of the original coverage area of the second radio transmitter, such that the set of modified signal emission and reception settings enables the set of first radio transmitters to serve as a substitute for the second radio transmitter in regard to coverage and capacity of the original coverage area of the second radio transmitter, while maintaining at least a minimum quality of service for radio signals within the first radio cells; and - storing the modified set of signal emission and reception settings as preset configurations for the subset of first radio transmitters. - determining signal-data characterizing the coverage and capacity of the first radio cells by radio signals provided by the first and second radio transmitters; - determining signal-data characterizing the coverage and capacity of the second radio cell by radio signals provided by the first and second radio transmitters; - determining performance values characterizing the coverage and capacity of the first and second radio cells using the signal-data of radio signals provided by the first radio transmitters, - determining the signal emission and reception settings of the set of first radio transmitters; - determining a set of modified signal emission and reception settings for the set of first radio transmitters in order to enhance performance values of the original coverage area of the second radio transmitter, such that the set of modified signal emission and reception settings enables the set of first radio transmitters to serve as a substitute for the second radio transmitter in regard to coverage and capacity of the original coverage area of the second radio transmitter, while maintaining at least a minimum quality of service for radio signals within the first radio cells; and - storing the modified set of signal emission and reception settings as preset configurations for the subset of first radio transmitters.
