Matching method and system for transmitting capability of STA (Station) and AP (Wireless Access Point)

Abstract

The invention provides a matching method and system for a transmitting capability of a STA (Station) and an AP (Wireless Access Point). The method and the system are applied to a WLAN network. The method comprises the steps of obtaining parameters of the STA and the parameters of each candidate AP which will be accessed by the STA; calculating a bandwidth utilization rate of each candidate AP which will be accessed by the STA according to the parameters of the STA and the parameters of the candidate APs; calculating a spectrum resource utilization rate of each candidate AP which will be accessed by the STA according to the parameters of the STA and the parameters of the candidate APs; calculating comprehensive transmission capability matching degree of each candidate AP which will be accessed by the STA according to the bandwidth utilization rates and the spectrum resource utilization rates; and selecting the candidate AP with the highest comprehensive transmission capability matching degree as the accessing AP of the STA. According to the method and the system, the matching degree of the STA and the AP is ensured, so that the resource utilization degree of the whole WLAN network is improved, and the throughput and the maximum accessing number of users of the network are improved.

Description

technical field [0001] The invention belongs to wireless network selection technology and multi-attribute decision-making technology, in particular to a WLAN (WirelessLocal Area Networks, wireless local area network) based STA (Station, site) and AP (wireless Access Point, wireless access point) transmission Capability matching method and system. Background technique [0002] In recent years, in order to meet the needs of the rapid development of data services, WLAN networks have been widely used in wireless network communications, especially in some hot spots of data services, such as Wifi campus networks, and the WLAN network is also dense , that is, the same terminal will be under the coverage of multiple Wifi AP bands at the same time. In order to prevent a large number of STAs from accessing the same AP band and cause the AP band to be overloaded or even interrupt services, the dynamic load balancing technology between AP bands has become a WLAN networking A hot spot o...

AI Technical Summary

Problems solved by technology

[0009] At present, the attribute indicators considered by the WLAN network decision-making algorithm are mainly concentrated on the network status indicators. These methods can guarantee the load balancing and service quality of STAs between AP bands to a certain extent, but it may be because the capabilities of STAs and APbands do not match. As a result, WLAN network resources cannot be utilized to the greatest extent.

For example: if figure 1 As shown, AP1 and STA2 support a bandwidth of 80M, while AP2 and STA1 only support a bandwidth of 20M. The two networks have similar attributes in other aspects, and the types of services performed by STA are also consistent. In this scenario, if the decision only considers the network status, the matching result shown in the above figure may appear, that is, STA1 is associated with AP1, and STA2 is associated with AP2, and finally only 20M of bandwidth can be used, resulting in a waste of bandwidth resources, resulting in a decrease in the maximum number of access users and throughput of the network. decline

[0010] In addition, Aruba Networks mentioned the ability to monitor STAs in the ClientMatch technology, but did not see how to establish a STA capability model to participate in decision-making
