A master monitor/control (“M/C”) unit selects a base station controller (“BSC”) to serve a mobile radio base station (“RBS”). In one embodiment, the master M/C unit is configured to monitor and assess performance parameters of a communications link between the mobile RBS and a serving BSC and alternative communications links between the mobile RBS and a plurality of other BSCs. The master M/C unit is also configured to determine if the performance parameter of an alternative communications link between the mobile RBS and one of the plurality of other BSCs is better than the performance parameter of the communications link between the mobile RBS and the serving BSC, and select the one of the plurality of other BSCs as an alternative BSC accordingly. The master M/C unit is also configured to provide a new configuration for the mobile RBS and the alternative BSC to enable the alternative communications link therebetween.
