Method and system for dynamic spectrum allocation, and computer program product therefor

摘要

A communication network such as a cellular network or a WLAN includes a set of user terminals. Within the communication network, a system dynamically controls spectrum usage. The system includes a functionality sensor for sensing spectrum usage within the area covered by the communication network, and a policy server for producing, as a function of the sensed spectrum usage, spectrum usage policies for the communication network. A broadcasting arrangement broadcasts the spectrum usage policies to the user terminals. The system is applicable to cognitive radio systems.
