Embodiment 1

[0034] The embodiment of the present invention provides a method for dynamically switching channels, such as figure 1 As shown, the method includes:

[0035] Step 101: Detect the signal strength of the data sent by the interfering AP on the current working channel;

[0036] Wherein, the AP mentioned in step 101 refers to the interfering AP for the AP performing step 101, and the signal strength of the data sent by the AP mentioned in step 101 causes interference to the AP working on the current channel. For the convenience of understanding, the AP mentioned in step 101 may be referred to as an "interfering AP" subsequently.

[0037] The AP performing the detection in step 101 can receive the data sent by the interfering AP, or the data sent to the interfering AP. These data can be unencrypted data packets, or beacon (Beacon) frames sent by the interfering AP, or The Probe Response sent.

[0038] Step 102: judging whether the detected signal strength is greater than the swit...

Embodiment 2

[0055] The embodiment of the present invention provides a method for dynamically switching channels. The method is similar to the method provided in Embodiment 1. When the detected signal strength is greater than the switching threshold, the channel is switched to a channel with less interference. The difference is that the method provided in the second embodiment is based on the same inventive concept as the first embodiment, and provides a more complete and intelligent channel switching solution. specific reference figure 2 As shown, the method includes:

[0056] Step 201: start the timer, and trigger the execution of step 202 after a set time interval;

[0057] Step 202: Detect the signal strength of data sent by the interfering AP on the current working channel;

[0058] Among them, there are three common types of data sent by the AP (whether it is an executing AP or an interfering AP), but not limited to the following three types:

[0059] One is the data packet used ...

Embodiment 3

[0075] An embodiment of the present invention provides a device for dynamically switching channels, such as image 3 As shown, the device includes: a first detection unit 301 , a judgment unit 302 , a second detection unit 303 , and a switching unit 304 .

[0076] The first detection unit 301 is used to detect the signal strength of the data sent by the interfering AP on the current working channel;

[0077] Wherein, the AP mentioned in the first detection unit 301 refers to the interfering AP for the AP performing step 101, and the signal strength of the data sent by the AP mentioned in the first detection unit 301 interferes with the AP working on the current channel. For the convenience of understanding, the AP mentioned in the first detecting unit 301 may be referred to as an "interfering AP" subsequently.

[0078] The AP performing the detection can receive the data sent by the interfering AP, or the data sent to the interfering AP. These data can be unencrypted data pac...

Abstract

An embodiment of the invention discloses a method for dynamically switching channels. The method includes detecting signal intensity interfering data transmission of an access point on a current operating channel; judging whether the signal intensity detected is larger than switching threshold or not; detecting signal intensity interfering data transmission of the access point in an effective channel when the signal intensity detected is larger than the switching threshold; switching to one effective channel from the current operating channel, wherein signal intensity interfering data transmission of the access point in one effective channel is detected to be smaller than the switching threshold at least. By detecting the signal intensity interfering data transmission of the AP (access point) on the current operating channel, the signal intensity interfering data transmission of the AP in one effective channel is detected when the signal intensity detected is larger than the switching threshold, and a low-interfered channel in the effective channels is selected to be a new operating channel, so that the AP has higher signal transmission efficiency and provides higher-quality wireless networking experience for users.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for dynamically switching channels. Background technique [0002] Wireless access point (AP, Access Point) is a wireless switching device used for wireless networks. It is the access point for mobile terminal users to enter the wired network. It is mainly used in broadband homes, inside buildings, and inside campuses. It ranges from meters to thousands of meters. Currently, it mainly supports WiFi technical standards. Its downlink can be connected to a WiFi workstation (STA, Station) as an access device for users to access WAN. For example, a user's notebook is connected to the operator's AP as a STA. ; Or, the AP is used as the access device for the user to access the LAN, such as: the AP is connected to the Asymmetric Digital Subscriber Line (ADSL, Asymmetric Digital Subscriber Line) or other broadband methods to access the Internet through routing. ...
