Method for fast and reliable dynamic common channel setup and reconstruction in point-to-point dynamic spectrum allocation networks

Embodiments of the present invention relate to common channel setting and, more specifically, to a fast and reliable dynamic common channel setting method between two nodes in a DSA network environment. According to an embodiment of the present invention, provided is a new method for configuring a channel change mechanism of a callee who responds to a channel setting request to communicate by using a common channel in the process of setting a channel between the nodes, thereby enabling the communication by setting the communication channel efficiently in a short time.
