Monitor the wireless channel.

When the first wireless access component is disconnected and is in a disconnected state, the second wireless access component replaces the first wireless access component as a main physical link, and performs network connection through a second wireless channel. At this time, the first wireless access component can be determined to be in a monitoring state, and the first wireless channel can be monitored to ensure that when the network connection established by the second wireless access component is abnormal, the first wireless access Enter the component and switch back to the network connection established through the first wireless channel.

In a possible implementation manner, in response to the electronic device disconnecting the network connection between the first wireless access component and the wireless network, the electronic device uses the first wireless access component to connect to the second wireless channel except for Wireless sub-channels other than the first wireless sub-channel are monitored.

After the electronic device establishes a connection with the wireless network through the second wireless access component through the first wireless sub-channel, the first wireless access component is in a listening state, and the first wireless access component is in addition to the first wireless channel. In addition to monitoring, the second wireless channel can also be monitored on wireless sub-channels other than the first wireless sub-channel, and the signal strength can be found in other wireless channels except the first wireless sub-channel. Higher and more stable wireless channel.

In a possible implementation manner, when the first wireless access component is in a disconnected state for a third specified time period, the electronic device determines that the first wireless access component is in a listening state, so as to use the first wireless access component The component listens to the first wireless channel.

When the first wireless access component is in the disconnected state and reaches the third specified time period, the first wireless access component is determined to be in the listening state, which can avoid the electronic device being in the first wireless access component due to network instability. Frequent handover between the connected wireless network and the wireless network connected to the second wireless access component avoids unnecessary resource consumption.

The method proposed in this scheme can use idle Wi-Fi independent hardware devices to realize real-time detection of wireless air interface environment, and indirectly estimate the busy state (CCA detection) by listening to the busy state of the non-current working channel through the configured real-time channel traversal background scan. Monitor the interference of the channel, and report the RSSI, SSID, BSSID and other information of the 802.11 frame of the wireless air interface to the upper layer, and cooperate with the software algorithm to detect the interference strength, so as to lock and select the potential secondary working channel and provide it to the upper layer Software a better channel quality selection.

Once the current working network has unstable services or large jitter, and thus does not meet the current normal service requirements (such as real-time voice services, Gaming scenarios, etc.), the upper layer will cooperate with the previously idle Wi- The internal hardware of Fi establishes a new wireless network connection. Once the connection is completed, it notifies the upper layer of service switching, and the service layer can open two independent port communication at the same time. The link is disconnected, as a detection link, so as to realize the Ping-Pong operation on the physical connection.

The implementation steps can be as follows:

1) After the Wi-Fi module is started, and the upper-layer APP software counts only one main physical link working for a period of time, the state of the other auxiliary idle physical link is in the Ready state;

2) The upper layer can work in the listening state after the secondary link is issued by the configuration command (pay attention to avoid the current main working channel and working bandwidth at the same time, to prevent the false statistics of the interference state), then the secondary link periodic timing is in different non-interference states. Enable background scanning between working frequency points, record the busy status of the CCA monitoring channel, and mark the status of the idle physical link as the Monitor status. Parameters such as the dwell time of each channel, the list of monitoring channels, and the monitoring period of CCA can be modified through the configuration commands issued;

3) The upper-layer APP records the SSID, BSSID of each monitoring channel and the signal strength RSSI of the matching frame, and simultaneously utilizes the CCA busy state of the channel to sequentially calculate the amount of interference and the strength indication of each channel, and the statistical results are updated in real time;

4) When continuous service is not smooth or the jitter is large in the main working channel, it can be concluded that the current working main channel can no longer meet the current business needs. , according to the RTT delay or the physical layer rate of sending Tx and receiving Rx to indirectly evaluate the maximum throughput and effectiveness of the current network connection, to select the best auxiliary link working channel, while maintaining the physical network link;

5) Once the new physical network connection is established, the upper-layer APP is notified, the physical link migration of the main network can be realized, the network request for disconnecting the first wireless access component is sent, and the second wireless access component is marked as the main working link. For Working, the first wireless access component is marked as a secondary working link, and the state is Ready. The monitoring function may continue to be implemented by using the secondary physical link of the first radio access component as required.

In this solution, the idle secondary Wi-Fi physical link is used as the interference monitoring mode, which can dynamically monitor the amount and strength of the interference of the non-working channel in real time, and report the monitoring status to the upper-layer application, so as to realize the business capability of the main working channel. When the requirements are not met, alternative channels can be selected to realize seamless switching of network status. This solution keeps only one physical link working at the same time, so it has more advantages in power consumption compared to the physical links with multiple connections at the same time. This solution can continuously monitor the optimal working channel in the current working environment, thereby ensuring that the next network handover has a higher handover success rate and satisfies the fluency of services.

Please refer to FIG. 6 , which is a flow chart of a wireless network switching method according to an exemplary embodiment. As shown in Figure 6, the wireless network switching method includes the following steps:

S602, the electronic device detects whether the electronic device is connected to two channels simultaneously through two physical links, and when the electronic device is simultaneously connected to two channels through two physical links, it indicates that the two physical links ( That is, the two wireless access components) are in the connected state, and the working state of the two physical links continues to be detected. When the electronic device detects that the electronic device is not connected to the two channels, it can be considered that the The second wireless access component is in a disconnected state. S603, the electronic device determines the current connection (ie, the second wireless access component) as a ready state, and determines that the second wireless access component is not connected at this time, and the electronic device can perform the second wireless access component at any time. configuration. S604, the electronic device determines the current connection as a monitor state, uses the second wireless access component to monitor all channels except the channel corresponding to the main connection, and obtains monitoring results of the respective channels. S605, when the monitoring of each channel by the electronic device using the second wireless access component is not completed, continue to monitor each channel by using the second wireless access component, and when the second wireless access component monitors each channel After completion, upload the monitoring result to the upper-layer application. S606, when the upper-layer application detects that there is a problem with the network connection corresponding to the main connection, the first channel corresponding to the main connection (ie, the first wireless access component) is determined to be in an abnormal state, and according to the second wireless connection The monitoring result of the incoming component is used to determine the wireless channel to be accessed by the second wireless access component, and then the second wireless access component is used to access the wireless channel to implement the switching process between the primary connection and the secondary connection. S607, the electronic device can determine whether to configure the first wireless access component in the disconnected state after switching to the listening state, when the electronic device configures the first wireless access component in the disconnected state to the listening state, the first wireless access component in the disconnected state One wireless access component is the secondary connection, and the second wireless access component is the primary connection, and the above steps S601 to S606 are re-executed; when the electronic device does not continue to monitor, the process ends.

Through the above steps, the terminal can switch the idle wireless access component to the idle wireless access component when the network connection state of the working wireless access component is not good by configuring the idle wireless access component to the listening state, and The channel with the best channel condition monitored by the wireless access component can realize seamless handover of the wireless network only by configuring the idle wireless access component to be in the listening state, thereby reducing the resource consumption of the terminal.
