Wireless router and method for switching frequency band of access terminal

Abstract

The invention discloses a wireless router and method for switching the frequency band of an access terminal. The wireless router comprises a monitoring module, a determining module, a switching indication module and a switching module; the monitoring module monitors an RSSI parameter of the terminal connected to the wireless router; according to the RSSI parameter and a dynamic switching threshold of a present frequency band, the determining module determines requirements that the terminal needs to satisfy for switching; the switching indication module stops sending a message to the terminal in the present frequency band so as to indicate the terminal to send a frequency band switching request; and after receiving the frequency band switching request from the terminal, the switching module reestablishes connection with the frequency band after switching of the terminal. According to the invention, the threshold is adjusted dynamically to adapt to different network environments, the switching speed is improved, and the network surfing speed of users is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer networks, in particular to a wireless router and a method for switching frequency bands for access terminals. Background technique [0002] In the era of smart devices blowout, wireless routers have become the most important electrical equipment in the family. 2.4G and 5G refer to the transmission frequency of the wireless router respectively. The 5GHz signal has the advantages of wide frequency band, low interference, and high throughput rate, but the 5GHz signal has poor ability to penetrate walls. In contrast, the 2.4GHz signal has a slightly narrower bandwidth, but It has the advantage of wide coverage, and the transmission of 5GHz signals requires higher channel quality than the transmission of 2.4GHz signals. At present, there are some wireless routers that support dual-band, that is, the two frequency bands of 2.4G and 5G are turned on at the same time, but only one freque...

Problems solved by technology

[0006] Since the handover trigger uses a fixed threshold, it cannot be well adapted to all network environments

[0007] For example, the actual wireless network environment will be different due to factors such as weather, surrounding wireless network, house structure, wall material, etc. The wireless network environment of each family is different, and it is impossible to cover all network environments by means of fixed thresholds

As a result, some users still cannot switch frequency bands normally during use, or the switching is not sensitive enough, and users access the Internet slowly.
