摘要：In cellular networks the continuity of communication has high significance in real-time services, therefore, the Handover (HO), transferring communication from one base station to another one, always has been the main concept of all mobiles generations. In cellular networks for avoidance of frequency interference, different channel allocation scheme are proposed; static, semi-static and dynamic schemes. Dynamic scheme allocates frequency band more efficient. However, dynamic schemes usually are not used by operators because of the too much signaling overhead. We propose a new scheme for resource allocation based on Cognitive Radio (CR) technology to use provide frequency bands for HO. While the frequency bandwidth allocated to an operator is specified this opportunity exist with CR technology the frequency of the same network, which is employed for the farther distances, recognize and get used, to supply the required resources for HO. We named our proposed HO schemes Cognitive Radio Handover (CRHO).
