CHANNEL FREQUENCY SPECTRUM RESOURCE SELECTION METHOD, DEVICE AND CHANNEL FREQUENCY SPECTRUM RESOURCE SELECTION SYSTEM

摘要

Disclosed in embodiments of the present invention is a method for selecting channel frequency spectrum resources, which is used for selecting a target channel according to channel needs, so as to meet the needs of operators. The method of the embodiments of the present invention comprises: a first device sending a frequency spectrum query request to a second device, the frequency spectrum query request comprising channel feedback information for instructing the second device to feed back information of a currently available channel to the first device; the first device receiving a frequency spectrum query response sent by the second device, the frequency spectrum query response comprising the information of the currently available channel; the first device selecting a target channel from the information of the currently available channel, wherein the target channel corresponds to a channel demand of the first device.
