Method and system for providing service quality guarantee in wireless network

Abstract

The invention discloses a method and a system for providing service quality guarantee in a wireless network. The method comprises the following steps of: dividing network coverage into a plurality of coverage types and setting a service quality parameter set corresponding to each coverage type; selecting a coverage type matched with the current wireless network access equipment from the plurality of coverage types and configuring the service quality parameters for the current wireless network access equipment according to the parameter set of the matched coverage type; and managing a service request of the user terminal by using the current wireless network access equipment according to the configured service quality parameters and a preset relationship between a user terminal and the wireless network. In the wireless network deployed in a large scale, the utilization rate of network resources can be increased and the service quality in the application coverage range can be improved integrally by the method and the system.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method and system for providing service quality assurance in a wireless network. Background technique [0002] First, define the acronyms that will be used in the specification below as follows: [0003] WLAN (Wireless Local Area Network), wireless local area network; [0004] AP (Access Point), an access point, provides network access services for the Station, which can be a wireless network access device; [0005] STA, that is, Station (station) is a user terminal in WLAN, and Station can access the network after association with AP; [0006] QoS, that is, Quality of Service, quality of service; [0007] TXOP, that is, Transmission Opportunity, transmission opportunity; [0008] TSPEC, Traffic Specification, transmission specification. [0009] With the development of technology, video and voice services have gradually become a hotspot in a WLAN (Wireless ...

Problems solved by technology

[0026] Therefore, there is nothing wrong with the existing implementation methods in ordinary, small-scale deployed WLAN networks, but in centralized control WLANs deployed by network access service providers on a large scale, there will be some unsolvable problems. problems, such as in figure 2 Shown in a large-scale deployed WLAN network:

[0027] ●In actual deployment, the distribution of services in different regions is different. In some hot spots, such as office buildings, etc., there are more low-priority data services, while in airports, there are more high-priority voice services. When deploying a large-scale network, it is impossible to set the parameters related to the access type differently AP by AP, and if the parameters related to the access type are set according to the same standard, the effective utilization rate of the bandwidth will be reduced-for example, if the voice service is also set as 20% of the total capacity, it may cause waste in areas such as conference rooms, and may not be enough in areas such as airports and office buildings, thus reducing the user experience in the area as a whole;

[0028] ●Because the AP does not have the ability to distinguish the actual type of data, the STA may artificially improve the QoS of some services. Impact on the QoS of real video service users
