Embodiment Construction

[0018] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] At the beginning of the wireless connection establishment, the AP first scans each channel, obtains the interference signal strength on the scanned channel, determines an optimal channel, and after establishing a connection with the optimal channel, transmits data through this channel. Due to the complexity of the existing wireless network environment, the same channel is often used by multiple different APs. Therefore, in the pro...

Abstract

The embodiment of the invention discloses a wireless channel switching method and an AP (Access Point). The wireless channel switching method comprises the following steps: detecting interference signal intensity and packet loss probability of the AP on a connection channel; detecting that the interference signal intensity is more than a first threshold value and the packet loss probability is more than a second threshold value, and sending a channel switching inquiring message to the access point; and determining a target switching channel and sending a channel switching command to the access point so that the access point is switched to the target switching channel. The interference signal intensity and the packet loss probability on the connection channel are judged and the condition of the connection channel is comprehensively considered; when the interference signal intensity and the packet loss probability do not meet setting requirements, the target switching channel is determined from each scanned channel and is switched, so that the connection channel is dynamically switched to a better channel when the connection channel is interfered and the possibility of problems of data retransmission, frame waiting, frame collision and the like, caused by channel seizing, in a transmission process of wireless data, is effectively reduced.

Description

technical field [0001] The invention relates to the field of real-time streaming media, in particular to a wireless channel switching method and an AP. Background technique [0002] AP (Access Point, wireless access point) is a wireless switching device for a wireless network, and is an access point for a mobile terminal user to enter a wired network. It is mainly used in broadband homes, inside buildings, and inside parks, with coverage ranging from tens of meters to thousands of meters. At present, it mainly supports the Wireless-Fidelity (Wi-Fi) technical standard, and its downlink can be connected to a Wi-Fi workstation as an access device for users to access WAN (Wide Area Network, WAN), such as: the user's The notebook is used as an access station to connect to the operator's AP; or, the AP is used as an access device for users to access the LAN (Local Area Network, local area network). For example, the AP is connected to the ADSL (Asymmetric Digital Subscriber Line, ...
