Claim Text:
1. A dynamic spectrum allocation method based on channel management, comprising: generating, by a network node, a channel set according to an available channel list and channel classification information, and maintaining and updating the channel set; and selecting, by the network node, a spectrum from the channel set and allocating the spectrum; wherein the channel classification information includes one or more of the following items: a channel quality status, a channel idle time, limitations on channel transmitting parameters, the geographical isolation of a channel and a channel spectrum frequency; wherein the channel quality status is a quantity capable of reflecting the quality of a useful signal received by a receiver when a secondary system uses the idle spectrum of a primary system; the channel idle time refers to the time span from a specific moment to the moment of the reuse of a channel by the primary system; the limitations on channel transmitting parameters include one or more of the following items: a limitation on the maximum transmitting power, a limitation on an adjacent channel leakage power ratio, a limitation on stray radiation and a limitation on the maximum channel-allowed interference level; the geographical isolation of a channel refers to the natural isolator existing in a radio environment and/or the distance between the transmitter of the secondary system and the coverage edge of the primary system; and the channel spectrum frequency refers to the start frequency, the stop frequency or the center frequency of a channel spectrum.
