Abstract: For a terminal located in any area of a first cell in a first system, a sum of actual interference of all second cells to any spectrum resource to be used by the terminal can be determined according to a pre-established interference matrix for representing historical reference interference of each second cell in a second system to each area in the first cell and a spectrum resource real-time occupation status of each second cell; when it is determined that the sum does not exceed a preset interference threshold value range, it is determined that the terminal can use the any spectrum resource; or when it is determined that the sum exceeds a preset interference threshold value range, it is determined that the terminal cannot use the any spectrum resource.
