Abstract
In a trunked communication system with a number of repeaters (101, 103, 105, 107), allocation of communication resources within each coverage area is controlled by one of the repeaters, which acts as an active resource controller. Communication resource control information is distributed between the repeaters via a data network (109). When a break (113) is detected (403) in the data network (109), a secondary communication unit (117) sends a notice of the break (405) to the plurality of repeaters located on each side of the break. The active resource controller determines which side of the break provides desired usage of the communication resources, and communications are maintained by that side (505, 509).
