Dynamic configuration method of intensive local area network environment broadband channel

Abstract

The invention discloses a dynamic configuration method of an intensive local area network environment broadband channel, which belongs to the technical field of mobile communication and mainly solves the problems of frequency spectrum waste and incapability of meeting users' requirements of broadband service caused by the fact that the existing channel broadband distribution method can not be adjusted dynamically. Achieving steps of the method include: (1) choosing different methods to conduct initial channel selection for an access point (AP); (2) collecting, classifying and checking environment parameter information; (3) judging whether the AP needs broadband expansion according to checked environment information parameters, conducting decision judgment according to the environment information parameters of the AP if the AP needs broadband expansion, and requesting the AP to configure the expansion channel again; (4) the AP conducts corresponding reconfiguration according to different decision judgment requests; and (5) access users of each AP conduct relevance with the AP again according to requests of each AP to finish a channel adjusting process. The dynamic configuration method can meet the users' requirements of broadband service, adapts to dynamic changes of a network, and improves use rate of frequency spectrum, throughput of a system and performance.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a method for dynamically adjusting channel and working channel bandwidth allocation among each access point AP and each workstation STA within the coverage range of the access point in a large-scale intensive wireless local area network. Background technique [0002] Wireless local area network (WLAN) provides a wireless connection service of local area network, which can provide high-speed data transmission in a small area. Because of its flexibility, high throughput, low cost and good integration with the Internet, WLAN's Development is no longer a simple application to play a role in shunting the cellular network indoors. With the emergence of hot spots such as coffee shops, airports, hotels, convention centers, business plazas, and civic leisure plazas, WLAN application areas have become more and more extensive; in recent years, the development of wireless elec...

Problems solved by technology

However, due to the lack of unified centralized management and scheduling in the current network channel configuration, it is often impossible to find an idle and independent channel that can be directly bundled to form a 40MHZ channel. The working bandwidth cannot meet the suddenly increased user business needs. If the working bandwidth cannot be dynamically expanded to adapt to network changes, user services will be interrupted or discarded, and even the entire network will be paralyzed in severe cases.
