Method for searching resources in radio LAN

Abstract

The method comprises: user sends the description message of the resources to be looked up to the coprocessor; the coprocessor expands the management frame of the Probe Request, and encapsulating the description message of the resource to be looked up into the Probe Request to broadcast; the processor in the radio network terminal receiving the Probe Request resolves the description message in the Probe Request management frame and sends the description message to user; if user determines to give a response, and sends the response content to the processor of the terminal, the processor encapsulating the response content in an expanded Probe Response frame to send out; the processor in device receiving the Probe Response management frame Resolves the content of the Probe Response frame and sends it to user.

Description

technical field [0001] The invention relates to a method for searching resources, in particular to a method for searching resources in a wireless local area network of 802.11 standard. Background technique [0002] At present, 802.11-related technologies have become a series of IEEE standards, such as 802.11a / b / g / n / i / e and so on. Wireless local area network products mainly adopt the IEEE (Institute of Electrical and Electronics Engineers) 802.11b international standard, and most of them use DSSS (Direct Sequence Spread Spectrum) communication technology for data transmission, which can effectively prevent data from being transmitted wirelessly. Problems such as loss, interference, information blocking and destruction during transmission. Related products such as network card, wireless access point AP (Access Point) and wireless router have been sold in large quantities on the market. [0003] In the field of wireless communication, compared with other wireless local area n...

Problems solved by technology

[0004] In the prior art, a special application is represented by a fixed SSID, so that the corresponding application can be known only by scanning the SSID, and then accessed and used; but in this case, other applications that do not provide this type of application Once a device is connected to a network with such an SSID, after the original device that provides this type of application goes offline, the SSID will still be sent by other devices that are connected to the network but do not provide application support, making other devices that need to use the application mistakenly believe that there is an SSID. The corresponding application exists

[0005] In the above-mentioned existing solutions, how to know what applications and resources are on the unconnected network cannot be realized through the existing 802.11; and when accessing the network, the user needs to configure it, but this configuration is difficult for ordinary users even those with technical skills. background users are confusing, inconvenient and impossible
