Wireless fidelity wi-fi connection method, device and communication system

Abstract

The present invention relates to a Wi-Fi connection method, device and communication system, the method comprising: obtaining information of the previous Wi-Fi WAN side channel; configuring the current Wi-Fi LAN according to the information of the previous Wi-Fi WAN side channel Side channel; receive the connection establishment request of the user equipment UE, and establish a connection with the UE through the current Wi-Fi LAN side channel; query the currently available Wi-Fi access point, and establish a connection with the Wi-Fi access point; where, with The Wi-Fi access point establishes a connection through the current Wi-Fi WAN side channel; when the current Wi-Fi WAN side channel is consistent with the current Wi-Fi LAN side channel, then store the information of the Wi-Fi WAN side channel. The embodiment of the present invention realizes the non-interrupted establishment of a communication connection between the UE and the Wi-Fi hotspot without changing the hotspot.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a Wi-Fi connection method, device and communication system. Background technique [0002] As the wireless fidelity (Wireless Fidelity, Wi-Fi) technology becomes increasingly mature, the coverage of Wi-Fi hotspots becomes larger and larger, and network communication devices supporting Wi-Fi uplink become more and more popular. At present, existing mobile network communication devices, such as mobile wireless routers, mostly adopt Wi-Fi single-chip solutions to realize Wi-Fi uplink and downlink functions, which require Wi-Fi wide area network (Wide Area Network, WAN) side and Wi-Fi local area network ( Local Area Network, LAN) side performs data services on the same channel. figure 1 It is a signaling diagram of the current method for realizing Wi-Fi connection. When the mobile network communication device is turned on or wakes up from standby, the network communica...

AI Technical Summary

Problems solved by technology

When the mobile network communication device is turned on or wakes up from standby, the network communication device will randomly and automatically assign a Wi-Fi channel to be used as a downlink channel to connect to user equipment UE, such as a computer, mobile phone, etc., and when the network communication After the device connects to a new Wi-Fi access point (access point, AP) through Wi-Fi uplink, the downlink channel in the device will switch with the Wi-Fi uplink channel to ensure that the uplink and downlink are on the same channel, so will cause the connection between the network communication device and its connected computer or mobile phone to be interrupted for a short period of time
