The present invention relates to the field of wireless communications technologies, and is mainly used in a broadcast multicast service, so as to coordinate multiple access devices to apply for a same band of white frequency spectrum. The method includes: a controller sending first application information to a database (201), the first application information being used for applying for a frequency band of frequency spectrum for at least one access device; the controller receiving the frequency band of the frequency spectrum sent by the database (202); and the controller sending the frequency band of the frequency spectrum to the access device (203)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, device, and system for applying for frequency spectrum","description":"A method, a device, and a system for applying for frequency spectrum are provided.
