Abstract
The present invention provides a method for updating a white space spectrum, an access device and a communication system, where the method performed by the access device includes: acquiring feature information of a white space spectrum, wherein the white space spectrum is currently used by the access device for communicating with a terminal, and the feature information comprises information about a bandwidth and a central frequency of the white space spectrum; sending an update request that comprises the feature information to a spectrum database device; and communicating with the terminal by using the white space spectrum identified by the feature information when a response for the update request from the spectrum database device indicates that the white space spectrum is available. The present invention optimizes a process of updating a white space spectrum.
