Abstract: A mobile communication system that establishes a link between a plurality of base stations in which an adjacency condition is satisfied. The mobile communication system including a first base station that transmits a broadcast packet including its own location information and radius information of a wireless service area. Also included is a second base station that determines the adjacency condition between the wireless service areas based on the location information of the first base station and the radius information of the wireless service area, included in the packet received from the first base station, and the second base station's location information and the radius information of the wireless service area. The link is preferably established between the first and second base stations in which the adjacency condition is satisfied.

Abstract: A mobile communication system enable the higher-level devices of a wireless base station to comprehend the trends (prediction) of adaptive modulation control performed by the wireless base station, which is a lower-level device. A mobile communication system wherein adaptive modulation control is executed between a mobile station and a wireless base station comprises a transmission processor operable to transmit information relating to parameters used in the adaptive modulation control to a higher-level device of the wireless base station.
