Embodiment Construction

[0020] As shown in the figure, the present invention is a network rate adaptive adjustment method in a wireless broadband access network, the steps of which include:

[0021] 1. Associate the relevant devices. If the association fails, you need to adjust the physical distance between the terminal and the access point. If the association is successful, start setting the initial rate of both devices;

[0022] The setting of the initial rate is related to the conditions of the rate adjustment. The rate adjustment uses a timer. The longer the rate adjustment interval, the higher the initial rate, and the shorter the rate adjustment interval, the lower the initial rate. relatively balanced effect.

[0023] 2. After the timer completes a time period, it detects the sending of data packets within this time period. When the sent data packets meet the threshold H, the number of rate increase requests is increased by 1. When it does not meet the threshold H, it detects whether the thres...

Abstract

The invention relates to a self-adapting method for adjusting network transmission rate in wireless broadband access networks, which includes the following steps: the transmission state of data packets is detected in a given time period by a timer; transmission rate is up-regulated when transmitting data packets meet threshold H; the transmission rate is down-regulated when transmitting data packets meet threshold L instead of threshold H; transmission rate is not regulated when transmitting data packets meet neither threshold H nor threshold L; in which, threshold H is equal to (FER is less than A) and amp; and amp; (10 multiplied by the number of data packets retransmitted is less than the number of data packets which are not retransmitted); L is equal to (FER is more than B) and amp; and amp; (3 multiplied by the number of data packets retransmitted is more than the number of data packets which are not retransmitted); the FER represents the error probability of a frame. The invention has the advantages by which the operation is simple and easy to implement, the network transmission rate can be controlled and monitored at any time, and the coverage of wireless networks can be enlarged effectively to ensure that users enjoy customized wireless broadband access services with high speed data transmission based on stable and reliable transmission rate.

Description

technical field [0001] The invention relates to a rate adjustment method of a wireless local area network, in particular to a network rate self-adaptive adjustment method in a wireless broadband access network. Background technique [0002] Wireless local area network has become one of the fastest-growing high-speed wireless access networks at present. It enables people to completely get rid of the shackles of wired cables and enjoy the fun brought by high-speed wireless Internet access. With the continuous development of wireless local area network technology, the price of wireless products continues to drop, more and more offices and families start to use wireless local area network, followed by some users began to have network congestion problems, resulting in network speed drop, dropped , the network is not working properly and so on. [0003] The wireless local area network specification is from the early IEEE802.11b to the current IEEE802.11a / g. In a wireless environm...
