Abstract
The invention discloses a kind of low-rate users connection control method, comprise the following steps: access point AP detects a transmission rate that sends successful Frame to user, if when the transmission rate of this Frame is less than first threshold, this Frame is low rate frame; If sent after the low rate frame of predetermined number N to described user continuously, judge that this user is for low-rate users; In the time that AP detects that the number of Frame in the transmit queue of described low-rate users is greater than Second Threshold, lose the Frame that mails to described low-rate users. The technical scheme that adopts the present invention to propose, can solve that low-rate users takies hardware resource and the problem that causes the performance of network entirety to reduce effectively.
Description
Technical field
The present invention relates to field of wireless communication, especially promote WLAN low-rate users control application.
Background technology
Compared with cable network, WLAN has broken away from the constraint of cable, user use can feel freer,More convenient. Therefore,, along with popularizing of the portable terminal devices such as notebook, WLAN becomes common network insertion day by dayMode.
The 802.11b of IEEE802.11 working group design is at first operated in 2.4Ghz, and speed is 2Mbps. ArriveConstantly upgrading of IEEE design afterwards, to 802.11a, is operated in 5Ghz, and speed is up to 54Mbps; To 802.11g,Speed or 54Mbps, design frequency is operated in 2.4Ghz, compatible 802.11b; The 802.11n of up-to-date releaseCan be operated in 2.4Ghz, also can be operated in 5Ghz, use MIMO technology speed up to 600Mpbs. IEEE802.11 working groups still, continuing, design higher traffic rate, and WLAN technology also becomes in LTE technologyOne, with WINMAX, WCDMA, CDMA technology forms competitive complement relation.
WLAN is mainly by station (Station, STA), access point (AccessPoint, AP), wireless medium(WirelessMedium, WM) and distributed system (Dis-tributionSystem, DS) composition. (STA) stands.STA is generally client in WLAN, can be the computer that wireless network card is housed, and can be also to have WiFiThe smart mobile phone of module. STA can be mobile, also can fix, and is the most basic of WLANComponent units. In WLAN, STA is by associated message, and access access point AP, then carries out data communication,As shown in Figure 1.
Because the propagation medium of WLAN is air, the consensus standard of following is 802.11, brings to user at itSimultaneously easily, also there are some particularity of self. Such as, the wireless device of cochannel is shared the transmission of eating dishes without rice or wine and is situated betweenMatter, easily interacts between equipment. Dispose well the place that user is less, wireless user's experience at signalMay be similar with wire user. But in the more highly dense place of user, using section in rush hour, usually can go outThe phenomenon that existing speed slowly, easily goes offline.
In prior art, in WLAN, when having low-rate users to access and downloading, weak user can take moreAP device hardware resource, if low-rate users is not controlled in wireless driving, cause two-fortyUser's networking speed can be very slow,
Summary of the invention
In order to solve the problems of the technologies described above, the present invention proposes a kind of low-rate users connection control method, pass throughWhen the user of low rate downloads in restriction WLAN, occupy too much hardware resource, realize low rate is usedThe communication process at family limits.
Particularly, the present invention proposes a kind of low-rate users connection control method, comprise the following steps:
S101, access point AP detects a transmission rate that sends successful Frame to user, if shouldWhen the transmission rate of Frame is less than first threshold, this Frame is low rate frame;
S102, if sent after the low rate frame of predetermined number N to described user continuously, judges that this user isLow-rate users;
S103, detects that as AP the number of Frame in the transmit queue of described low-rate users is greater than the second thresholdWhen value, lose the Frame that mails to described low-rate users.
According to a further aspect of the invention, wherein first threshold described in step S101 according to AP transmitting power and letterRoad environment is determined.
According to a further aspect of the invention, wherein in step S102, described N can get 5,10,15,20 or25。
According to a further aspect of the invention, wherein in step S103, described Second Threshold can be 5,10,15,20 or 25.
The low-rate users connection control method that the present invention proposes, in the time ensureing that low-rate users accesses and downloads,Do not affect the networking speed of other normal users in WLAN, effectively improved network performance.
Brief description of the drawings
Below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
Fig. 1 is STA and the AP communication scheme in WLAN;
Fig. 2 is the flow chart that judges low-rate users in technical solution of the present invention;
Fig. 3 is the flow chart of in technical solution of the present invention, low-rate users being controlled restriction;
Fig. 4 is the flow chart of low-rate users connection control method in technical solution of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcementExample, is further elaborated to the present invention. Should be appreciated that specific embodiment described herein only usesTo explain the present invention, be not intended to limit the present invention.
Referring to Fig. 2, it is the flow chart that judges low-rate users, wherein, and access point AP (AccessPoint)Detect a transmission rate that sends successful Frame, if the transmission rate of this Frame is less than the first thresholdValue, this Frame is low rate frame, if sent after the low rate frame of predetermined number N to certain user continuously,Judge that this user is for low-rate users.
Referring to Fig. 3, it is for controlling the flow chart limiting to low-rate users, wherein to low-rate usersCan control is mainly that the number of Frame by this user in restriction transmit queue realizes. When AP detectsWhile being greater than Second Threshold to the number of the middle Frame of low-rate users transmit queue, just starting to lose and mail to low speedRate user's Frame, thus the hardware resource that the Frame of low-rate users occupies controlled.
Specifically the low-rate users connection control method that, the present invention proposes comprises 2 parts, Part IFor the determination step of low-rate users, the control section that Part II is low-rate users, referring to Fig. 4, thisMethod in bright comprises the following steps:
S101, access point AP (AccessPoint) detects a transmission rate that sends successful Frame,If when the transmission rate of this Frame is less than first threshold, this Frame is low rate frame;
S102, if sent after the low rate frame of predetermined number N to certain user continuously, judges that this user isLow-rate users;
S103, detects that as AP the number of the middle Frame of the transmit queue of described low-rate users is greater than secondWhen threshold value, lose the Frame that mails to described low-rate users.
Wherein, first threshold described in S101 is determined according to AP transmitting power and channel circumstance.
Wherein, in S102, described N can get the integer values such as 5,10,20 or 30.
Wherein, in S103, described Second Threshold can be the integer values such as 5,10,15,20 or 25.
The present invention determines low-rate users by AP to the transmission rate of user terminal, then low by restrictionThe number of the transmit queue Frame of rate users realizes the Access Control to low-rate users. Adopt the present invention,Effectively solve that low-rate users takies hardware resource and the problem that causes the performance of network entirety to reduce.
In sum, although the present invention discloses as above with preferred embodiment, but it is not in order to limit thisBright. General technical staff of the technical field of the invention, without departing from the spirit and scope of the present invention, canDo various variations and modification. Therefore, protection scope of the present invention is when the scope defining depending on appended claimBe as the criterion.
