Description
Technical field
The present invention relates to communication technical field, in particular to the communicator of a kind of communication means of WLAN (wireless local area network), a kind of WLAN (wireless local area network), a kind of website and a kind of access point.
Background technology
In May, 2013,802.11 have set up the seminar HEW (HighefficiencyWLAN of Wi-Fi technology of future generation, efficient WLAN (wireless local area network)), i.e. 802.11ax, main research point improves the throughput of existing Wi-Fi technology, the effective utilization ratio improving frequency spectrum, raising Consumer's Experience and service quality Q oE (QualityofExperience), and realize the communication environment adapting to more crypto set than existing Wi-Fi technology.
More the communication environment of crypto set refer to communication process in there is more OBSS (OverlappingBasisServiceSet, the Basic Service Set intersected), if there is more OBSS, then mean that in the process of communication, have more communication contention aware occurs, in order to reduce the generation of communication contention aware, mainly contain the following two kinds solution at present:
1, in standard formulation process, adopt the Color mechanism defined in 802.11ah standard, i.e. AP (AccessPoint, access point) in communication process, BSS (BasisServiceSet is set, Basic Service Set) Color value, represent the duration existing for this BSS, as AP sets up multiple BSS, its value is identical;
2, CCA (ClearChannelAssessment is changed, channel idle detect) value, the value of CCA is used for STA (Station, website) NAV (NetworkAccessVector is set, network allocation vector), NAV is used for the standard of the judge accessing channel as STA.
Quantity due to OBSS directly has influence on the quality of communication, and that is the quantity of communication contention aware can increase along with the increase of the quantity of OBSS.Due to certain AP may cover by other AP, as shown in Figure 1, suppose that A, B, C represent different AP respectively, A may can not be covered by B and C, same, B may can not be covered by A and C, and C may can not be covered by A and B, so AP may arrange wrong to the Color value of itself and CCA value, and then may cause the increase of communication contention aware.

AP is after receiving the information that STA reports, and the Color value reported according to STA and CCA value, adjust Color value and the CCA value of himself BSS dynamically.
Wherein, the Color value that AP arranges himself BSS comprises AP and arranges the duration that the number of its Basic Service Set and/or Basic Service Set exist.
In addition, HESTA can carry the ability information that it can support to report Color value and CCA value in the process of proberequest (probe requests thereby) or associationrequest (association request); Accordingly, AP can broadcast in Beacon (beacon) frame or proberesponse (probe response) frame its arrange after the Color value information of BSS and CCA value information.
As shown in Figure 8, according to the communication means of the WLAN (wireless local area network) of the 3rd embodiment of the present invention, comprising:
Step 801, website 1 adds up the quantity of BSS and CCA value corresponding to BSS.
Step 802, website 1 generates the first message frame, comprises the number information of BSS that website 1 adds up and CCA value corresponding to BSS in the first message frame.
Step 803, website 1 sends the first message frame.
Step 804, access point 2 receives the first message frame.
Step 805, access point 2 arranges the CCA value of access point 2 and the quantity of BSS according to the first message frame, also can arrange the duration that BSS exists.
Step 806, generates the second message frame, comprises the number information of Basic Service Set and the CCA value of access point 2 of access point 2 setting, also can comprise the duration that access point 2 arranges BSS existence in the second message frame.
Step 807, access point 2 sends the second message frame.
Step 808, website 1 receives the second message frame.
Step 809, website 1 obtains the CCA value of access point 2 setting and the quantity of BSS from the second message frame, also can get the duration that access point 2 arranges BSS existence.
More than be described with reference to the accompanying drawings technical scheme of the present invention, the present invention proposes a kind of communication plan of new WLAN (wireless local area network), make access point can set out the number of CCA value and Basic Service Set comparatively accurately, with the generation of contention-free as far as possible, indirectly improve the throughput of system.
