Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0023] A WLAN network includes at least one AP and one STA, and generally includes multiple APs and multiple STAs. The association process for any AP to receive any STA is consistent, and the association process for any STA to associate with an AP or with other STAs is also consistent. Therefore, in the present invention, the entire association is described in detail by associating any STA with any AP process and message sending process.

[0024] see figure 1 , figure 1 It is a flow chart of the data compression transmission method in the embodiment of the present invention. The specific steps are:

[0025] In step 101, any STA obtains the data compression algorithm supported by each AP.

[0026] Step 102, the STA sends an associat...

Abstract

The invention discloses a data compressing and transmitting method based on a WLAN (wireless local area network), and the method comprises the following steps of: obtaining data compression algorithms supported by all APs (access points) by virtue of any one STA (static timing analyzer); sending an association or reassociation message of adding a data compression supporting label and a selected self-supporting data compression algorithm, and notifying the data compression algorithm to be associated and to be negotiated by the APs, wherein the selected data compression algorithm is one of the data compression algorithms supported by the APs; receiving an association response message carrying the data compression supporting label and the corresponding data compression algorithm and sent by the APs; and if the message is necessary to be sent to the APs at present, adding the label of carrying out data compression into the message, compressing a load by adopting the negotiated compression algorithm, and sending the load. Based on the same inventive concept, the invention further provides the AP and the STA both of which can adequately utilize the limited bandwidth of the WLAN.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a WLAN network-based data compression transmission method, STA and AP. Background technique [0002] The access service provided by the WLAN network is based on the CDMA / CA access mode, and each wireless terminal shares the access medium, that is, the air interface. This determines that the bandwidth that each terminal can obtain is limited after all. In order to transmit more traffic on a link with limited bandwidth, data compression is a commonly used technique. There is no standard to provide this technology at present, and the limited bandwidth of WLAN cannot be fully utilized. Contents of the invention [0003] In view of this, the present invention provides a WLAN network-based data compression transmission method and device. Can make full use of the limited bandwidth of WLAN. [0004] In order to solve the problems of the technologies described above, the tech...
