Channel allocation method and channel allocation device used in wireless communication system

Abstract

The invention provides a channel allocation method and a channel allocation device used in a wireless communication system. The method comprises the steps of allocating a working channel for each application (AP) in the wireless communication system according to a principle of smallest conflict of the allocated working channels of adjacent APs; allocating an idle channel for the AP with the working channel in the wireless communication system; combining adjacent APs meeting following conditions in the wireless communication system so as to form a connected region, wherein the same number of identical idle channels and the allocated working channels are bonded and the bandwidth satisfies bandwidth rank of bonded channels permitted by the wireless communication system, and the connected region occupies the idle channels forming the connected region; and controlling the APs in the connected region to share the idle channels occupied by the connected region, and controlling each AP in the wireless communication system except the APs in the connected region to bond the allocated idle channel and working channel so as to form a broadband broad channel for use. Through adoption of the method, the APs can fully use left idle channels while not disturbing each other as far as possible.

Description

technical field [0001] The present application relates to network communication technology, in particular to a channel allocation method and device applied in a wireless communication system. Background technique [0002] In a wireless communication system, the number of available non-interfering channels is limited. For example, in the WLAN2.4G frequency band, the number of available non-interfering channels is 3, and in the WLAN5G frequency band, the number of available non-interfering channels is 3. It is also limited, generally only a maximum of 6 channels are available. When a certain number of access points (AP: Access Point) in the wireless communication system are covered, in order to optimize the system performance of the wireless communication system, when assigning working channels to APs from the available channels of the wireless communication system, it is generally necessary to Different working channels are allocated between APs to reduce channel interferenc...

Problems solved by technology

However, in the prior art, there is no method that can make full use of the remaining idle channels between APs without interfering as much as possible.
