METHOD FOR OBTAINING WHITE FREQUENCY SPECTRUM RESOURCE, DEVICE AND SYSTEM FOR REQUESTING WHITE FREQUENCY SPECTRUM

摘要

Embodiments of the present invention provide a white space resource acquisition method, a white space resource request device, and a system. The white space resource acquisition method provided in the embodiments of the present invention includes: receiving, by the white space resource request device, a white space resource request message sent by a white space device; and sending, by the white space resource request device, a white space resource response message to the white space device, where the white space resource response message includes white space resource information that is requested from a white space database and corresponding to first white space requirement information of the white space device. According to the white space resource acquisition method provided in the embodiments of the present invention, a white space resource request device requests white space resource information from a white space database based on the PAWS protocol, and interaction between a white space device and the white space resource request device may be established by using an existing protocol, so that the white space device does not need to establish a connection to the white space database so as to acquire a white space resource, and no new interface needs to be defined to support the PAWS protocol.
