Abstract
The invention discloses a low rate user access control method. The low rate user access control method comprises the following steps: an access point (AP) detects the sending rate of a data frame which is previously sent to a user successively, if the sending rate of the data frame is smaller than a threshold value, the data frame is low-rate frame; if predetermined number N of low-rate frames are successively sent to the user, the user is judged to be a low-rate user; when AP detects that the number of data frames in a sending array of the low-rate user is bigger than a second threshold value, the data frames sent to the low-rate user are dropped. The low rate user access control method can effectively solve the problem that the internet integral performance is reduced due to the fact that the low-rate user occupies hardware resources.
Description
Technical field
The present invention relates to field of wireless communication, especially promote the WLAN (wireless local area network) low-rate users and control application.
Background technology
Compare with cable network, WLAN has broken away from the constraint of cable, and the user uses and can feel freer, more convenient.Therefore, along with popularizing of the portable terminal devices such as notebook, WLAN becomes common network access mode day by day.
The 802.11b of initial IEEE802.11 working group design is operated in 2.4Ghz, and speed is 2Mbps.Constantly upgrading of IEEE design finally 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 release can be operated in 2.4Ghz, also can be operated in 5Ghz, uses MIMO technology speed up to 600Mpbs.IEEE802.11 working group is still continuing, and design higher traffic rate, and the WLAN technology also becomes a kind of in the LTE technology, with WINMAX, WCDMA, and CDMA technology formation competitive complement relation.
WLAN mainly is comprised of station (Station, STA), access point (Access Point, AP), wireless medium (Wireless Medium, WM) and distributed system (Dis-tribution System, DS).(STA) stands.STA is generally client in WLAN, can be the computer that wireless network card is housed, and can be also the smart mobile phone that the WiFi module is arranged.STA can be mobile, also can fix, and is the basic composition unit of WLAN (wireless local area network).In WLAN, STA is by related message, and then access access point AP 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, when it brings convenience to the user, some particularity of self is arranged also.Such as, the wireless device of cochannel is shared the transmission medium of eating dishes without rice or wine, and easily interacts between equipment.Dispose well at signal, the place that the user is less, wireless user's experience may be similar with wire user.But in the more highly dense place of user, using the section in rush hour, usually can occur speed slowly, the phenomenon that easily goes offline.
In prior art, in WLAN (wireless local area network), when having low-rate users to access and download, weak user can take more AP device hardware resource, if low-rate users is not controlled in wireless driving, causes the networking speed of high rate user 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, occupy too much hardware resource when downloading by the user who limits low rate in WLAN (wireless local area network), realize the communication process of low-rate users is limited.
Particularly, the present invention proposes a kind of low-rate users connection control method, comprise the following steps:
S101, access point AP detects a upper transmission rate that sends successful Frame to the user, if the transmission rate of this Frame during less than first threshold, this Frame is low rate frame;
If S102 after sending the low rate frame of predetermined number N to described user continuously, judges that this user is low-rate users;
S103, the number that Frame in the transmit queue of described low-rate users detected as AP is lost the Frame that mails to described low-rate users during greater than Second Threshold.
According to a further aspect of the invention, wherein first threshold described in step S101 is determined according to AP transmitting power and channel circumstance.
According to a further aspect of the invention, wherein in step S102, described N can get 5,10,15,20 or 25.
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 when guaranteeing that low-rate users accesses and downloads, does not affect the networking speed of other normal users in WLAN, has effectively improved network performance.
Description of drawings
The present invention is further described in more detail below in conjunction with drawings and the specific embodiments.
Fig. 1 is STA and the AP communication scheme in WLAN;
Fig. 2 is the flow chart of judgement low-rate users in technical solution of the present invention;
Fig. 3 controls the flow chart of restriction to low-rate users in technical solution of the present invention;
Fig. 4 is the flow chart of low-rate users connection control method in technical solution of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Referring to Fig. 2, it is the flow chart of judgement low-rate users, wherein, access point AP (Access Point) detects a upper transmission rate that sends successful Frame, if the transmission rate of this Frame is less than first threshold, this Frame is low rate frame, if after sending the low rate frame of predetermined number N to certain user continuously, judges that this user is low-rate users.
Referring to Fig. 3, it is wherein mainly to realize by the number that limits this user's Frame in transmit queue to controlling of low-rate users for low-rate users being controlled the flow chart of restriction.The number of middle Frame that the low-rate users transmit queue detected as AP just begins to lose the Frame that mails to low-rate users during greater than Second Threshold, thereby has controlled the hardware resource that the Frame of low-rate users occupies.
Specifically, the low-rate users connection control method that the present invention proposes comprises 2 parts, and first is the determination step of low-rate users, and second portion is the control section of low-rate users, and referring to Fig. 4, the method in the present invention comprises the following steps:
S101, access point AP (Access Point) detect a upper transmission rate that sends successful Frame, if the transmission rate of this Frame during less than first threshold, this Frame is low rate frame;
If S102 after sending the low rate frame of predetermined number N to certain user continuously, judges that this user is low-rate users;
S103, the number of middle Frame of transmit queue that described low-rate users detected as AP is lost the Frame that mails to described low-rate users during greater than Second Threshold.
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, and then the number of transmit queue Frame by the restriction low-rate users realizes the access control to low-rate users.Adopt the present invention, solved effectively that low-rate users takies hardware resource and the problem that causes the performance of network integral body to reduce.
In sum, although the present invention with the preferred embodiment disclosure as above, yet it is not to limit the present invention.The general technical staff of the technical field of the invention without departing from the spirit and scope of the present invention, can do various changes and modification.Therefore, protection scope of the present invention is as the criterion when looking appended the scope that claim defines.
