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).
Claims8
A method of distributing control in a trunked communication system with distributed control of allocation of communication resources amongst a plurality of repeaters in a coverage area via a data network between at least two of the plurality of repeaters, comprising the steps of:
- detecting a break in the data network;
- sending by a radio a notice of the break to the plurality of repeaters located on each side of the break;
- determining which side of the break provides desired usage of the communication resources;
- maintaining the side of the break with said desired usage.
A trunked communication system with distributed control of allocation of communication resources amongst a plurality of repeaters in a coverage area via a data network, the trunked communication system comprising:
- means for detecting a break in the data network;
- means, coupled to said means for detecting, for sending via a communication resource a notice of the break to the plurality of repeaters located on each side of the break;
- means, coupled to said means for detecting, for determining which side of the break provides desired usage of the communication resources;
- means, coupled to said means for determining, for maintaining the side of the break with said desired usage.
