A method for accessing a network, said method being implemented by a network access device, the method comprising steps of: receiving (201, 502) a request message requesting for accessing the network, wherein the request message is broadcast by a first communication device, wherein the request message contains a device identification of the first communication device; detecting (202, 503) a current state of the network access device; if the network access device is currently in a device access forbidding state, sending (203, 504) a state switching request to a terminal for which a binding relationship is established with the network access device in advance, wherein the state switching request contains the device identification of the first communication device; receiving (204, 508) a reply message sent by the terminal, the reply message being generated by the terminal based on the state switching request and containing a target device identification, the target device identification being a device identification selected from the device identification list by a user of the terminal; and if the reply message instructs switching the state of the network access device to a device access permitting state, switching (205, 509) the state of the network access device to a device access permitting state; characterized in that the step (203, 504) of sending a state switching request to a terminal for which a binding relationship is established with the network access device in advance comprises steps of: generating a device identification list, the device identification list recording a device identification of each communication device which sends a request message during a preset time period since a moment when the request message sent by the first communication device is received by the network access device; and sending, to the terminal for which a binding relationship is established with the network access device in advance, the state switching request containing the device identification list. receiving (201, 502) a request message requesting for accessing the network, wherein the request message is broadcast by a first communication device, wherein the request message contains a device identification of the first communication device; detecting (202, 503) a current state of the network access device; if the network access device is currently in a device access forbidding state, sending (203, 504) a state switching request to a terminal for which a binding relationship is established with the network access device in advance, wherein the state switching request contains the device identification of the first communication device; receiving (204, 508) a reply message sent by the terminal, the reply message being generated by the terminal based on the state switching request and containing a target device identification, the target device identification being a device identification selected from the device identification list by a user of the terminal; and if the reply message instructs switching the state of the network access device to a device access permitting state, switching (205, 509) the state of the network access device to a device access permitting state; characterized in that the step (203, 504) of sending a state switching request to a terminal for which a binding relationship is established with the network access device in advance comprises steps of: generating a device identification list, the device identification list recording a device identification of each communication device which sends a request message during a preset time period since a moment when the request message sent by the first communication device is received by the network access device; and sending, to the terminal for which a binding relationship is established with the network access device in advance, the state switching request containing the device identification list. generating a device identification list, the device identification list recording a device identification of each communication device which sends a request message during a preset time period since a moment when the request message sent by the first communication device is received by the network access device; and sending, to the terminal for which a binding relationship is established with the network access device in advance, the state switching request containing the device identification list.
