Embodiments of this specification provide a communication channel management method and apparatus. A specific embodiment of the method is performed by a wireless access point (AP) device, including the following steps: At the wireless access point (AP) device end, an original management frame that carries a target information element is constructed, where the target information element includes an information element related to communication channel management. When it is determined that one or more clients are connected to the AP device, for each client connected to the AP device, a target address of the constructed management frame is set to a MAC address of the client, and information in the target information element is encrypted by using a key corresponding to the client. Then, the management frame obtained after address setting and encryption is sent in a WiFi network.
