Taking as an example that when the frame is a Beacon frame, the first cell is an Advertisement Protocol, the second cell is a Vendor Specific, and the information carrying sub-cell is a Vendor Specific Content sub-cell, the following description is made to the embodiments of the present invention:
the WLAN herein refers to a Wireless Local Area Network, and is an abbreviation of Wireless Local Area Network. At present, almost all terminals are equipped with WLAN modules, and terminals with WLAN functions are divided into two categories, 1) the first category is terminals providing internet access service, called Access Points (AP), and an AP, that is, a wireless access point, is a creator of a wireless network, and is a central node of the network. For example, a wireless router used in a general home or office is an AP; 2) the second type is terminals using this access service, called STAs, to which terminals, such as laptops, PDAs and other network-enabled user equipments, each connected to the wireless network belong. After the AP is started, Beacon frames are regularly broadcasted on a set wireless channel, the Beacon frames contain basic information of the AP, and after the STA starts a WLAN function, the STA can scan the Beacon frames of all channels through a background to know which APs can be accessed currently. After establishing connection with the AP, the STA can access the Internet through the AP. Even if the STA is in the connected state, the STA still scans other APs nearby in the background. Since the propagation range of the WLAN signal is about 100m to 300m, the WLAN is a natural multimedia information providing scheme based on the location, so that after the user starts the WIFI function in the coverage range of the WLAN in the location, the user can access the WLAN to surf the internet and can also obtain the service information related to the location, such as the service information of airports and shopping malls and the like, as described above. Here, the multimedia information may be advertisement information, and the STA may provide a location-based advertisement service for the user by publishing the advertisement information in the Beacon frame issued by the AP and receiving the advertisement information in the Beacon frame.
At present, basic text advertisement information can be provided by setting a Service Set Identifier (SSID) of the AP. However, the SSID for advertising has a drawback that at most 32 bytes can carry very limited content, and for non-ASCII characters, less information can be carried by using UTF-8 encoding.
If Advertisement information is issued through the Beacon frame Advertisement Protocol cell, the cell can only carry 255 bytes at most, although simple text information can be carried, the data volume is not large enough, and multimedia information with larger data volume such as Logo cannot be carried. Although there may be a plurality of Vendor Specific cells, which can carry more information, it cannot be determined whether the cells are advertisement information. Because the current setting is that Advertisement information is issued by Advertisement Protocol cells, although there are a plurality of vector Specific cells, the vector Specific cells can bear more information but cannot determine whether the cells are Advertisement information, and the vector Specific cells need to be used in combination, so that the multimedia information with large data volume can be sent, and the multimedia information can also be determined to be Advertisement information, and a user can receive the Advertisement information service based on the position provided for the user.
The embodiment of the invention can send the advertisement information in the multimedia format at the access point terminal AP and receive the advertisement information in the multimedia format at the non-access point terminal based on the WLAN protocol, and data encapsulation and corresponding decapsulation are carried out through preset configuration, so that the sending and receiving of the advertisement information in the multimedia format by the WLAN are possible.
