Cognitive Radio (CR) can optimize system objects by dynamically assigning network resource and adjusting network operations in terms of network environments and conditions. So CR technology is very suitable for building emergency communication system to improve resource utilization ratio and enhancing dependability and availability of communication services apparently. In this paper, background requirements of constructing cognitive radio based emergency communication systems are expatiated and technical traits of CR are introduced. Then, network architecture and model of cognitive emergency communication system are proposed.
