For the geographic range that each is determined, described frequency management equipment determine exist use operating frequency identical with the frequency shared by corresponding frequency configuration region lease the base station of network time, the operating frequency that the base station determined should use is adjusted to the corresponding unappropriated idle frequence in frequency configuration region, and sends the frequency error factor instruction being switched to described idle frequence to the base station determined.
16. methods as described in claim 11 or 12, is characterized in that, also comprise:
Described spectrum detection device sends configuration order to described spectrum detection device, and described configuration order comprises time started of frequency spectrum detection, sense cycle and detection range;
The configuration order that described spectrum detection device sends according to described frequency management equipment, when the time started of frequency spectrum detection arrives, in described detection range to its for the frequency configuration region of authorisation network carry out periodic spectral detection.
