A network access permission management method, applied to a wireless fidelity Wi-Fi network, and comprising: • receiving, by a first station device in the Wi-Fi network, a network access permission update instruction generated by a configuration device in the Wi-Fi network, wherein the network access permission update instruction is used to instruct to update network access permission of a target device in the Wi-Fi network, and the network access permission update instruction comprises identification information of the target device and signature information of the configuration device, wherein the network access permission update instruction further comprises a network identifier of a network in which the target device is located (step 201); • verifying, by the first station device, the signature information (step 202); • updating, by the first station device, the network access permission of the target device according to the network access permission update instruction when the verification of the signature information succeeds (step 203); • receiving, by the first station device, a connection request message sent by a second station device, wherein the second station device is any device other than the first station device in the Wi-Fi network (step 204); and • accepting or rejecting, by the first station device, a connection request of the second station device according to the updated network access permission of the target device when: ∘ identification information of the second station device matches the identification information of the target device, and ∘ the network identifier is consistent with a network identifier of a network in which the second station device is located (step 205). • receiving, by a first station device in the Wi-Fi network, a network access permission update instruction generated by a configuration device in the Wi-Fi network, wherein the network access permission update instruction is used to instruct to update network access permission of a target device in the Wi-Fi network, and the network access permission update instruction comprises identification information of the target device and signature information of the configuration device, wherein the network access permission update instruction further comprises a network identifier of a network in which the target device is located (step 201); • verifying, by the first station device, the signature information (step 202); • updating, by the first station device, the network access permission of the target device according to the network access permission update instruction when the verification of the signature information succeeds (step 203); • receiving, by the first station device, a connection request message sent by a second station device, wherein the second station device is any device other than the first station device in the Wi-Fi network (step 204); and • accepting or rejecting, by the first station device, a connection request of the second station device according to the updated network access permission of the target device when: ∘ identification information of the second station device matches the identification information of the target device, and ∘ the network identifier is consistent with a network identifier of a network in which the second station device is located (step 205). ∘ identification information of the second station device matches the identification information of the target device, and ∘ the network identifier is consistent with a network identifier of a network in which the second station device is located (step 205).
