<p>A dynamic channel selecting method of a CR-based wireless communication system is provided to stably maintain communication, and maintain channel information according to the standards for selecting channels as selecting dynamically an idle channel. A terminal node senses information of a channel and transmits the sensed result to a base station(S11,S13). The base station stores/updates the transmitted channel information in a channel condition table(S15), and then determines whether a dynamic channel is selected to change the channel of the terminal node(S17). In case the dynamic channel selection is performed, the channel of the terminal node is selected through one of a sequential selection method, which sequentially applies each standard for channel selection according to the selection of a network user, a weight value selection method, which applies weight values to each standard for channel selection, and a mixed method in which the sequential selection method and weight value selection method are mixed.</p> |
