Abstract
The present invention discloses a method which is used by a service wireless network controller to acquire nonsupport combined serviceability. The combined serviceability combines a plurality of inputs, a plurality of outputs, and the modulation of integral amplitude of 64 times of the downlink. After the service wireless network controller sends a request message to a drift wireless network controller, the service wireless network controller acquires the information that the district under the control of the drift wireless network controller does not support the combination of the inputs, the outputs, and the modulation of integral amplitude of 64 times of the downlink through the response information of the drift wireless network controller. In the method, the service wireless network controller adopts the drift wireless network controller to acquire the information that the related district does not the combination of the MIMO and the downlink 64QAM, so as to judge whether the user equipment uses the combination of the MIMO and the downlink 64QAM and whether the link of the district should be deleted.
