Method for device to access network, access point, network access device, and system

A method for a device to access a network, comprising:

• receiving, by a first network access device, a broadcast frame broadcast by an access point, wherein the broadcast frame comprises feature information of a network access device;
• and the feature information is used for indicating a feature of the network access device;
• and
• determining, by the first network access device, whether the first network access device has the feature indicated by the feature information, and if the first network access device has the feature indicated by the feature information, initiating a network access procedure to the access point.

An access point, comprising:

• a generating module, configured to generate a broadcast frame, wherein the broadcast frame comprises feature information of a network access device;
• and the feature information is used for indicating a feature of the network access device;
• and
• a broadcasting module, configured to broadcast the broadcast frame, so that a specific network access device initiates a network access procedure to the access point, wherein the specific network access device is a network access device which receives the broadcast frame and has the feature indicated by the feature information.

A network access device, comprising:

• an obtaining module, configured to receive a broadcast frame broadcast by an access point, wherein the broadcast frame comprises feature information of the network access device;
• and the feature information is used for indicating a feature of the network access device;
• a determining module, configured to determine whether the network access device has the feature indicated by the feature information;
• and
• an accessing module, configured to initiate a network access procedure to the access point, when a determination result of the determining module is yes.
