Embodiment 1

[0027] see figure 1 The channel switching method of the wireless router provided by Embodiment 1 of the present invention includes the following steps:

[0028] S101, the wireless router monitors beacon frames (Beacon Frame) sent by other wireless routers;

[0029] S102. When receiving a beacon frame sent by another wireless router, the wireless router calculates a Received Signal Strength Indication (RSSI) corresponding to the beacon frame;

[0030] S103. The wireless router calculates and obtains a channel interference index according to the RSSI;

[0031] S104. The wireless router compares the channel interference index with a preset threshold;

[0032] S105. If the channel interference index reaches a preset threshold, the wireless router performs channel switching.

[0033] In Embodiment 1 of the present invention, since the subsequent processing is performed only when beacon frames sent by other wireless routers are received, the detection cycle will be dynamically ch...

Embodiment 2

[0035] see figure 2 The channel switching method of the wireless router provided by Embodiment 2 of the present invention includes the following steps:

[0036] S201. The wireless router monitors beacon frames sent by other wireless routers;

[0037] S202. When receiving a beacon frame sent by another wireless router, the wireless router calculates the RSSI corresponding to the beacon frame, and extracts the routing information for sending the beacon frame;

[0038] In Embodiment 2 of the present invention, the routing information for extracting and sending the beacon frame is specifically:

[0039] Extracting the SSID (Service Set Identifier, service set identifier, that is, the name of the wireless network) field of the beacon frame to obtain the SSID of the router sending the beacon frame.

[0040] S203. Determine whether the wireless router sending the beacon frame is in a bridging relationship with the wireless router according to the routing information, if yes, retur...

Embodiment 3

[0081] see Figure 4 , the wireless router provided by Embodiment 3 of the present invention includes: a first monitoring module 11, a first computing module 12, a second computing module 13, a comparing module 14 and a switching module 15, wherein,

[0082] The first monitoring module 11 is used to monitor beacon frames sent by other wireless routers;

[0083] The first calculation module 12 is used to calculate the received signal strength indicator RSSI corresponding to the beacon frame when receiving the beacon frame sent by other wireless routers;

[0084] The second calculation module 13 is used to calculate and obtain the channel interference index according to the RSSI;

[0085] A comparison module 14, configured to compare the channel interference index with a preset threshold;

[0086] The switching module 15 is configured to perform channel switching if the channel interference index reaches a preset threshold.

[0087] In Embodiment 3 of the present invention, t...

Abstract

The invention belongs to the field of wireless communication and provides a wireless router and a channel switching method thereof. The method comprises the steps that the wireless router monitors beacon frames sent by other wireless routers, the wireless router calculates received signal strength indicators (RSSI) corresponding to the beacon frames when the beacon frames sent by other wireless routers are received, a channel disturbance indicator is obtained through calculation according to the RSSI by the wireless router, the wireless router compares the channel disturbance indicator with a preset threshold value, and the wireless router conducts channel switch if the channel disturbance indicator reaches the preset threshold value. According to the wireless router and the channel switching method thereof, power consumption of the wireless router is reduced, the implementation platform is the wireless router, implementation does not rely on a third-party device, and therefore cost is low; furthermore, the problem that the network speed of the router becomes slow due to disturbance can be effectively solved, and the network speed is increased for users.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a wireless router and a channel switching method thereof. Background technique [0002] Wireless routers have gradually become popular in homes, and the problem of slow Internet access due to the interference of wireless routers between neighbors often occurs. The prior art provides a method and system for implementing channel switching in a wireless communication system. The realization of the technical solution mainly includes: firstly, detecting the interference parameter information of each channel in the wireless communication system; afterward, determining the channel meeting the predetermined channel switching condition according to the interference parameter information, and performing channel switching processing, and converting the The above-mentioned channel switching is used as the working channel. The technical solution effectively reduces the influence of int...
