Claim of US Patent No. 9,900,899

1. A dynamic spectrum allocation method, comprising steps of:
allocating, by a centralized node, a spectrum, and transmitting a spectrum allocation result to a communication node, so that
the communication node operates on a spectrum resource corresponding to the communication node in accordance with the spectrum
allocation result and performs statistics of communication quality measurement information;

receiving, by the centralized node, the communication quality measurement information reported by the communication node;
and

determining, by the centralized node, whether or not it is required to trigger the spectrum re-allocation for the communication
node in accordance with the communication quality measurement information about the communication node, and when it is required
to trigger the spectrum re-allocation for the communication node, re-allocating the spectrum for the communication node,

wherein the step of determining, by the centralized node, whether or not it is required to trigger the spectrum re-allocation
for the communication node in accordance with the communication quality measurement information about the communication node
comprises:

judging, by the centralized node, whether or not the communication quality measurement information about the communication
node exceeds a predetermined quality threshold, and when the communication quality measurement information about the communication
node does not exceed the predetermined quality threshold, determining that it is required to trigger the spectrum re-allocation
for the communication node.
