1. A method by a Cognitive Manager, CM, for controlling a radio access network, RAN, among a plurality of RANs of a radio communications system, the method comprising:
obtaining a set of local needs from the RAN, wherein each of the local needs identifies a radio communication performance criterion that is to be satisfied for the RAN;
obtaining from at least one neighbor CM configured to control at least one neighbor RAN a set of the neighbor needs for the at least one neighbor RAN;
receiving an event message from the RAN containing a radio communication performance metric that does not presently satisfy at least one of the set of local needs from the RAN;
obtaining from the at least one neighbor CM a set of present neighbor improvement action drives that are being performed or will be performed to satisfy the set of the neighbor needs for the at least one neighbor RAN;
combining the set of local needs from the RAN, the set of the neighbor needs obtained for the at least one neighbor CM, the set of present neighbor improvement action drives from the at least one neighbor CM, and the radio communication performance metric received in the event message from the RAN, wherein the combining includes using information received from the at least one neighbor CM to identify blind spots in communication service areas that are provided by the RAN and the at least one neighbor RAN and/or to identify target areas for communication services that are provided by the RAN and the at least one neighbor RAN;
determining, based on the combining, a local improvement action drive that is to be performed by the RAN to satisfy the at least one of the set of local needs from the RAN; and
providing an adjustment report to the RAN, the adjustment report identifying the local improvement action drive that is to be performed.
