Method and apparatus for acquirement of available spectrum

An apparatus for providing an available spectrum, the apparatus comprising a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions including a plurality of modules, the modules comprising:

• a receiving module, configured to receive an inquiring request from a master device, wherein the inquiring request carries location information of the master device and coverage range information of the master device;
• a determining module, configured to determine a covetable geographical range of the master device according to the location information of the master device and the coverage range information of the master device, and to determine information about the available spectrum within the covetable geographical range of the master device according to the covetable geographical range of the master device, a set of available spectra within a preset geographical range and a covetable geographical range of each available spectrum in the set of available spectra;
• and
• a sending module, configured to send the information about the available spectrum to the master device,
• wherein the inquiring request further carries capacity of the master device;
• wherein the determining module is further configured to determine whether the master device supports the available spectrum within the coverable geographical range of the master device according to the capacity of the master device received by the receive module;
• and
• wherein sending the information about the available spectrum to the master device is based on the determination that the master device supports the available spectrum within the coverable geographical range of the master device.
