Such as predefined, may refer to what is defined in the protocol.
Before describing the various embodiments shown herein, several concepts related to the present application will be described:
1)Wi-Fi
Wi-Fi, also called "action hotspot" in Chinese, is a brand authentication of products by the brand of Wi-Fi alliance manufacturers, and is a wireless local area network technology established in IEEE 802.11 standard. Based on the close correlation of the two systems, wi-Fi is often considered as a synonymous term of the IEEE 802.11 standard.
2) Link (Link)
A link refers to a passive point-to-point physical connection. In wired communication, a link refers to a physical line, such as a cable or fiber, between two nodes. In radio communication, a link refers to a path space for propagating electromagnetic waves between a base station and a terminal. In underwater acoustic communication, the link refers to the path space between the transducer and the hydrophone through which the acoustic wave propagates.
Reference is made to fig. 1, which is a schematic illustration of a network architecture of a communication system, according to an example embodiment. The network architecture may include: a terminal 10 and a network side device 20.
The same network-side device 20 may generally access multiple terminals 10 simultaneously. The terminal 10 can include various handheld devices, vehicle mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem with wireless communication capability, as well as various forms of User Equipment (UE), mobile Station (MS), terminal Equipment (terminal device), and so forth. For convenience of description, in the embodiments of the present application, the above-mentioned devices are collectively referred to as a terminal.
The network-side device 20 is an apparatus deployed in an access network to provide a wireless communication function for the terminal 10. The network side device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, and the like. In systems using different Radio access technologies, names of devices having a base station function may be different, for example, in a 5G New Radio (NR) system, called a nodeb or a gNB. The name "base station" may change as communication technology evolves. For convenience of description, in the embodiment of the present application, the above-mentioned apparatuses providing the terminal 10 with the wireless communication function are collectively referred to as network side devices.
Optionally, not shown in fig. 1, the network architecture further includes other network devices, such as: a Central Network Control (CNC), an Access and Mobility Management Function (AMF) device, a Session Management Function (SMF) or User Plane Function (UPF) device, and so on.
With the more mature Wi-Fi hardware technology and the expansion of the used frequency bands (2.4 GHz, 5GHz and 6 GHz), more and more Wi-Fi terminals have a dual-connection or multi-connection simultaneous use scene. Fig. 2 shows a schematic diagram of a hardware structure of a dual-connection chip. As shown in fig. 2, the Wi-Fi terminal has two or more sets of wireless Access components independent from each other implemented on a chip structure thereof, and each wireless Access component includes a Media Access Control (MAC) Layer, a Physical Layer (PHY) Layer, and a radio frequency antenna hardware configuration, so that each wireless Access component can work independently without mutual interference.
In practical use, most of the usage scenarios are that only one set of independent hardware works, and the other set of hardware is in a standby idle state (such as a scenario of simply using a mobile phone to access the internet). When the electronic equipment needs to ensure the stability of network connection, a plurality of sets of wireless access assemblies which are independent of each other can be used at the same time to be connected with Wi-Fi through different channels respectively, so that when the network accessed by one wireless access assembly is unstable, the wireless access assembly can be switched to the network accessed by another wireless access assembly in real time to ensure that the network connection is not interrupted, but the wireless access assemblies which are independent of each other are connected with a plurality of Wi-Fi simultaneously, and the resource consumption of the terminal is higher. The application provides a wireless network switching method, which can reduce resource consumption of electronic equipment while realizing seamless switching of network connection. Please refer to fig. 3, which is a flowchart illustrating a wireless network handover method according to an exemplary embodiment. The method may be performed by an electronic device, which may be the terminal 10 in the embodiment shown in fig. 1 described above. As shown in fig. 3, when the electronic device establishes a connection with a wireless network through a first wireless access component in a first wireless channel, the second wireless access component is in a no-network-connection state, and the flow of the wireless network switching method may include the following steps:
When the electronic device establishes a connection with a wireless network through a first wireless access component by using a first wireless channel and the second wireless access component does not establish a connection with the wireless network (i.e. the second wireless access component is in a no-network-connection state), if the first wireless channel is in an abnormal state (for example, disconnection or unstable connection), the first wireless channel is not suitable for being used as a channel corresponding to the network connection, and at this time, the electronic device can establish a connection with the wireless network through the second wireless access component in the no-network-connection state by using a second wireless channel.
After the electronic device establishes a connection with the wireless network through the second wireless access component and the second wireless channel, the electronic device already realizes network connection through the second wireless access component, and the network connection between the first wireless access component and the wireless network can be disconnected at this time, so that the power consumption of the electronic device is reduced.
In summary, in the solution shown in the embodiment of the present application, when the first wireless access component and the second wireless access component exist in the electronic device, and the first wireless access component establishes a connection with the wireless network, and the second wireless network is in a no-network-connection state, when the first wireless channel corresponding to the first wireless access component is in an abnormal state, the electronic device may establish a connection with the wireless network through the second wireless access component by using the second wireless channel, and disconnect the network connection of the first wireless access component after the connection is successful, so that the electronic device may implement seamless handover of the network without accessing two wireless networks simultaneously, and reduce resource consumption of the electronic device while ensuring seamless handover of the network.
Please refer to fig. 4, which is a flowchart illustrating a method for handing over a wireless network according to an exemplary embodiment. The method may be performed by an electronic device, which may be a terminal, wherein the terminal may be the terminal 10 in the embodiment shown in fig. 1 described above. As shown in fig. 4, the wireless network switching method may include the steps of:
Wherein the first listening information is listening information of the second radio access component to the second radio channel.
In one possible implementation manner, when the electronic device establishes a connection with a wireless network through a first wireless channel by using a first wireless access component and a second wireless access component is in a no-connection state, the electronic device determines the second wireless access component as a monitoring state.

The first wireless access component and the second wireless access component may be two sets of wireless access components independent from each other as shown in fig. 2, and at this time, the electronic device may establish a connection with a wireless network through the first wireless access component by using a first wireless channel, so that the first wireless access component may also be referred to as a main physical link; the second wireless access component may be referred to as a secondary physical link that may assist the electronic device in making network connections when the primary physical link is abnormal.
In a possible implementation manner, the electronic device has a first network application program that controls the Wi-Fi access component, and monitors that the first wireless access component is in an operating state and the second wireless access component is in a non-connection state through the first network application program, and when it is detected that the first wireless access component is in the operating state and the second wireless access component is in the non-connection state and is maintained for a first specified time, the first network application program may send a configuration command to the second wireless access component to indicate that the second wireless access component is in a monitoring state.
In one possible implementation manner, the first wireless channel is any one of wireless channels corresponding to the electronic device.
In a possible implementation manner, the electronic device monitors each wireless channel through the first wireless access component, obtains channel quality corresponding to each wireless channel, and determines the first wireless channel according to the channel quality corresponding to each wireless channel; the electronic equipment establishes connection with a wireless network through the first wireless access component by the first wireless channel.
In a possible implementation manner, the electronic device monitors at least one wireless sub-channel through the second wireless access component to obtain the first monitoring information.
The second wireless channel comprises at least one wireless sub-channel; the first monitoring information includes monitoring information corresponding to the at least one wireless sub-channel.
In a possible implementation manner, the second wireless channel is a wireless channel other than the first wireless channel in the wireless channel corresponding to the electronic device.
In a possible implementation manner, after the electronic device implements network connection through the first wireless access component by using the first wireless channel, the second wireless access component may detect a wireless channel (i.e., a second wireless channel) other than the first wireless channel, so as to avoid interference of detection of the second wireless access component on the first wireless channel while monitoring other idle channels.
In a possible implementation manner, after the electronic device issues a configuration command through a first network application program and a second wireless access component can operate in a monitoring state, the second wireless access component can monitor each wireless sub-channel in the second wireless channel and upload monitoring information to the first network application program, so that the first network application program can count channel states of each channel.
In a possible implementation manner, the monitoring information corresponding to the wireless sub-Channel includes at least one of an SSID (Service Set Identifier) corresponding to the wireless sub-Channel, a BSSID (Basic Service Set Identifier) corresponding to the wireless sub-Channel, an RSSI (Received Signal Strength) corresponding to the wireless sub-Channel, a CCA (Clear Channel Assessment) corresponding to the wireless sub-Channel, an RTT (Round-trip time) corresponding to the wireless sub-Channel, a physical layer rate of a transmitted packet corresponding to the wireless sub-Channel, and a physical layer rate of a Received packet corresponding to the wireless sub-Channel.
In a possible implementation manner, the electronic device determines each wireless sub-channel in the second wireless channel, and performs background scanning on each wireless sub-channel at a frequency point of each wireless sub-channel to obtain a channel state of each wireless sub-channel.
In a possible implementation manner, the electronic device performs background scanning on each wireless sub-channel at the frequency point of each wireless sub-channel according to a specified period through the second wireless access component, so as to obtain the channel state of each wireless sub-channel.
Wherein each wireless sub-channel in the second wireless channel, the specified period, and the listening time of each channel may be configured by the first network application.
In one possible implementation manner, when the first wireless channel is in an abnormal state, the first wireless sub-channel is determined in the at least one wireless sub-channel according to the first listening information.
Wherein, the first wireless channel is in an abnormal state, which means that the communication connection established between the first wireless access component and the first wireless channel is abnormal.
In one possible implementation, the electronic device detects a first network connection established by the first radio access component and the first radio channel, and determines the first radio channel as an abnormal state when detecting that the network quality of the first network connection is lower than a quality threshold.
When the network quality of the first network connection is detected to be lower than the quality threshold, it indicates that the first network connection established by the first radio access component and the first radio channel is not stable enough, and therefore the first radio channel is determined to be in an abnormal state.
In another possible implementation manner, the electronic device detects a first network connection established between the first radio access component and the first radio channel, and determines the first radio channel as an abnormal state when detecting that an error rate of information received through the first network connection is greater than an error threshold.
In another possible implementation manner, the electronic device detects a first application program, where the first application program is an application program that performs data transmission through a first network connection established between the first radio access component and the first radio channel, and determines that the first radio channel is in an abnormal state when detecting that data transmission of the first application program is abnormal.
In one possible implementation, the first application may be the first web application. That is, after the electronic device establishes the first network connection with the first wireless channel through the first wireless access component, the first network application may detect a data transmission status of the first network connection, and mark the first wireless channel as an abnormal status when detecting that the data transmission status of the first network connection is abnormal, so that the electronic device reselects the wireless channel for network connection.
In a possible implementation manner, when the first wireless channel is in an abnormal state, the electronic device obtains, according to the monitoring information corresponding to the at least one wireless sub-channel, a channel quality value corresponding to each wireless sub-channel in the at least one wireless sub-channel; the electronic equipment determines the first wireless sub-channel in the at least one wireless sub-channel according to the channel quality value corresponding to each wireless sub-channel in the at least one wireless sub-channel.
When the first wireless channel is in an abnormal state, it may be determined that the first wireless channel cannot meet the requirement of normal operation, and therefore, the electronic device may select a most suitable wireless channel among the second wireless channels as the first wireless sub-channel, so that the electronic device implements network connection with the first wireless sub-channel through the second wireless access component.
In a possible implementation manner, the electronic device determines at least one alternative sub-channel in the at least one wireless sub-channel according to the channel quality value corresponding to each wireless sub-channel in the at least one wireless sub-channel; the channel quality value of the alternative sub-channel is greater than the quality threshold; the electronic device determines the first wireless sub-channel among the at least one alternative sub-channel.
After obtaining the channel quality values respectively corresponding to the wireless sub-channels in the at least one wireless sub-channel, the electronic device may compare the channel quality values respectively corresponding to the wireless sub-channels with a quality threshold value to determine alternative sub-channels, so that when the first wireless channel is in an abnormal state, the first wireless sub-channel may be selected from the alternative sub-channels to implement network connection.
In a possible implementation manner, the electronic device obtains, by the first network application, monitoring information corresponding to each wireless sub-channel in the second channel, determines at least one available sub-channel according to the channel information, and determines the first wireless sub-channel according to a channel quality value of the at least one available sub-channel.
After the monitoring information corresponding to each wireless sub-channel in the second channel is detected, determining whether an accessible wireless network exists in each wireless sub-channel of the electronic device according to the SSID and the BSSID in each channel, and determining the wireless sub-channel as an available sub-channel when the accessible wireless sub-channel exists; the electronic device determines the signal attenuation degree of the wireless network available in each channel through the RSSI in each channel to determine the channel quality value of the available sub-channel, and determines the available sub-channel with the highest channel quality value as the first wireless sub-channel.
The electronic equipment records the SSID, BSSID and RSSI of each monitored channel and the signal strength of a matched frame through an upper application program, simultaneously calculates the interference of each channel and the strength indication in sequence by utilizing the CCA busy state of the channel, updates the statistical result in real time, and determines a first wireless sub-channel to be accessed by a second wireless access component according to the statistical result.
In a possible implementation manner, the monitoring information corresponding to each radio sub-channel further includes Round-Trip Time (RTT) delay or physical layer rate for transmitting Tx (transmission data) and receiving Rx (reception data) in each radio sub-channel.
That is, when continuous service is not smooth or jitter is large in the main working channel, it can be determined that the current working main channel cannot meet the current service requirement, the upper layer APP triggers the network connection of the auxiliary link, and the maximum throughput and the effectiveness of the current network connection are indirectly evaluated according to RTT delay or the sending/receiving physical layer rate from the alternative network connection in sequence to select the optimal auxiliary link working channel, and meanwhile, the physical network connection is maintained.
Please refer to fig. 5, which illustrates a physical link diagram of an electronic device according to an embodiment of the present application. As shown in fig. 5, the electronic device includes an upper application 501 (APP) and a WI-FI module 502, where the upper application includes an arbitration module, and the arbitration module is configured to instruct network connection with a wireless channel through any one of the WI-FI modules 502 or instruct network disconnection with the wireless channel through any one of the WI-FI modules 502.
In one possible implementation, the electronic device establishes a connection with a wireless network through the second wireless access component in the first wireless sub-channel.
After determining the first wireless sub-channel to be accessed by the second wireless access component, the electronic device can establish a connection with the wireless network through the second wireless component in the first wireless sub-channel.
At this time, the electronic device establishes a connection with the wireless network through the first wireless access component by using the first wireless channel, and the second wireless access component establishes a connection with the wireless network by using the first wireless sub-channel. That is, before the electronic device switches the physical link of the access network from the first wireless access component to the second wireless access component, a short dual-access process is required, that is, while the electronic device establishes a connection with the wireless network through the first wireless access component in the first wireless channel, the electronic device establishes a connection with the wireless network through the second wireless access component in the first wireless sub-channel, thereby avoiding disconnection of the network due to the physical link switching, and realizing seamless switching of the network.
In step 403, in response to the electronic device establishing a connection with the wireless network through a second wireless access component in the second wireless channel, the electronic device disconnects the first wireless access component from the wireless network.
When the electronic device detects that the second wireless access component is successfully connected with the wireless network through the second wireless channel, the physical link of the electronic device accessing the network and the successful switching are indicated, and at this time, the electronic device can disconnect the first wireless access component from the first wireless channel, so as to reduce the resource consumption of the electronic device.
In a possible implementation manner, after the electronic device establishes a connection with the wireless network through the second wireless access component in the second wireless channel for a second specified time, the network connection of the first wireless access component is disconnected.
When the successful connection with the wireless network through the second wireless access component by the second wireless channel is detected, the dual-connection state can be maintained for a period of time, and after the network connection established by the second wireless access component is disconnected, each application program of the electronic equipment, which needs to perform data transmission through the network, is successfully switched to perform data transmission through the network connection established by the second wireless access component, so that network interruption of some application programs caused by too fast switching is avoided.
In a possible implementation manner, the electronic device obtains an application program list corresponding to the first wireless access component, and when it is detected that all application programs in the application program list perform data transmission through the network connection established by the second wireless access component, disconnects the network connection of the first wireless access component.
When the electronic device needs to disconnect the network connection established by the first wireless access component, it is necessary to ensure that the disconnection of the network connection does not affect each application program in the electronic device, so that an application program list corresponding to the first wireless access component can be obtained first, an application program for performing communication through the network connection established by the first wireless access component is determined, when the application program for performing communication through the network connection established by the first wireless access component performs data transmission through the second wireless access component, the network connection of the first wireless access component is disconnected at this time, the application program of the electronic device is not affected, and the network connection of the first wireless access component can be disconnected at this time.
In one possible implementation manner, when the first wireless access component is in a connectionless state, the electronic device determines the first wireless access component as a listening state so as to listen to the first wireless channel through the first wireless access component.
When the first wireless access component is disconnected and in a connectionless 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 radio access component may be determined to be in a monitoring state, and the first radio channel may be monitored to ensure that the network connection established by the second radio access component is abnormal, and the network connection established by the first radio channel may be switched back through the first radio access component.
In one 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 listens to the wireless sub-channels other than the first wireless sub-channel in the second wireless channel through the first wireless access component.
After the electronic device establishes a connection with a wireless network through the second wireless access component by using the first wireless sub-channel, the first wireless access component is in a monitoring state, the first wireless access component can monitor the first wireless channel and can also monitor wireless sub-channels except the first wireless sub-channel in the second wireless channel, and a wireless channel with higher signal strength and more stability can be found in other wireless channels except the first wireless sub-channel.
In one possible implementation manner, when the first radio access component is in the connectionless state for a third specified duration, the electronic device determines the first radio access component as the listening state, so as to use the first radio access component to listen to the first radio channel.
When the first wireless access component is in a non-connection state and reaches a third specified duration, the first wireless access component is determined to be in a monitoring state, so that frequent switching of the electronic equipment between a wireless network connected with the first wireless access component and a wireless network connected with the second wireless access component due to network instability can be avoided, and unnecessary resource consumption is avoided.
The method provided by the scheme can realize real-time detection of the wireless air interface environment by using idle Wi-Fi independent hardware equipment, indirectly estimates the interference of an interception channel by traversing background scanning through the configured real-time channel and intercepting the busy state (CCA detection) of a non-current working channel, simultaneously reports the intercepted information of the wireless air interface 802.11 frame RSSI, SSID, BSSID and the like to an upper layer, and realizes the detection of the interference strength by matching with a software algorithm, thereby locking and selecting a potential secondary working channel and providing a better channel quality selection for upper layer software.
Once the current working network is unstable or has large jitter, so that the current normal service requirement is not met (such as real-time voice service, a Gaming scene and the like), the upper layer establishes a new wireless network connection by matching with the previous idle Wi-Fi internal hardware according to the previously locked secondary working channel, and once the connection is completed, the upper layer is informed of service switching, the service layer can simultaneously open two independent port communication, and after the other service channel is determined to be completed, the previously deteriorated physical link can be disconnected and used as a detection link, so that the Ping-Pong operation is realized on the physical connection.
The implementation steps can be as follows:
1) After the Wi-Fi module is started, the upper-layer APP software counts that only one main physical link works for a continuous period of time, and the state of the other auxiliary idle physical link is in a Ready state;
2) The upper layer can work in a monitoring state after sending an auxiliary link through a configuration command (the current main working channel and the working bandwidth are avoided at the same time to prevent the error statistics of the interference state), periodically and regularly enable background scanning at different non-working frequency points by the auxiliary link, record the CCA busy state of the monitoring channel, and mark the state of the idle physical link as a Monitor state. The dwell time of each channel, the monitoring channel list, the monitoring period of the CCA and other parameters can be modified through the issued configuration command;
3) The upper APP records the SSID, BSSID and signal strength RSSI of the matched frame of each monitored channel, and simultaneously calculates the interference and strength indication of each channel in sequence by using the CCA busy state of the channel, and the statistical result is updated in real time;
4) When continuous service is not smooth or jitter is large in a main working channel, the fact that the current working main channel cannot meet the current service requirement can be judged, an upper-layer APP triggers network connection of an auxiliary link, the maximum throughput and the effectiveness of the current network connection are indirectly evaluated according to RTT time delay or the physical layer rates of Tx sending and Rx receiving in the alternative network connection in sequence, the best auxiliary link working channel is selected, and meanwhile physical network connection is kept;
5) Once the new physical network connection is established, the upper layer APP is notified, the main network physical link migration can be realized, a network request for disconnecting the first wireless access component is sent, meanwhile, the second wireless access component is marked to be a main Working link, the state is Working, the first wireless access component is marked to be an auxiliary Working link, and the state is Ready. The listening function may continue to be implemented with the first radio access component secondary physical link as needed.
In the scheme, an idle auxiliary Wi-Fi physical link is used as an interference monitoring mode, so that the interference of a non-working channel can be monitored dynamically in real time, the monitoring state is reported and provided for an upper application program, and therefore when the service capacity of a main working channel does not meet the requirement, an alternative channel can be selected to realize seamless switching of a network state. The scheme keeps only one physical link to work at the same time, so that the scheme has more advantages in power consumption compared with the physical link with multiple connections at the same time. The scheme can continuously monitor the optimal working channel in the current working environment, thereby ensuring that the next network switching has high switching power and the smoothness of meeting services.
In summary, in the solution shown in the embodiment of the present application, when the first wireless access component and the second wireless access component exist in the electronic device, and the first wireless access component establishes a connection with the wireless network, and the second wireless network is in a no-network-connection state, when the first wireless channel corresponding to the first wireless access component is in an abnormal state, the electronic device may establish a connection with the wireless network through the second wireless access component by using the second wireless channel, and disconnect the network connection of the first wireless access component after the connection is successful, so that the electronic device may implement seamless handover of the network without accessing two wireless networks simultaneously, and reduce resource consumption of the electronic device while ensuring seamless handover of the network.

S602, the electronic device detects whether the electronic device connects two channels through two physical links, when the electronic device connects two channels through two physical links, it indicates that both physical links (i.e. two wireless access components) of the electronic device are in a connected state, and at this time, the working states of the two physical links are continuously detected, and when the electronic device detects that the electronic device is not connected to two channels, it may be considered that the second wireless access component is in an unconnected state. S603, the electronic device determines that the connection (i.e., the second wireless access component) is in the standby state, determines that the second wireless access component is not connected at this time, and the electronic device may configure the second wireless access component at any time. S604, the electronic device determines the secondary connection as a monitor (monitor) state, monitors all channels except the channel corresponding to the primary connection using the second wireless access component, and obtains a monitoring result of each channel. And S605, when the electronic device uses the second wireless access component to monitor each channel is not completed, using the second wireless access component to continue monitoring each channel, and after the second wireless access component completes monitoring each channel, uploading a monitoring result to an upper application program. S606, when the upper application detects that the network connection corresponding to the primary connection is faulty, determining the first channel corresponding to the primary connection (i.e. the first radio access component) as an abnormal state, determining the radio channel to be accessed by the second radio access component according to the monitoring result of the second radio access component, and accessing the radio channel through the second radio access component to implement the switching process between the primary connection and the secondary connection. S607, the electronic device may determine whether to configure the first wireless access component in the connectionless state after the handover to the monitoring state, and when the electronic device configures the first wireless access component in the connectionless state to the monitoring state, the first wireless access component is a secondary connection, the second wireless access component is a primary connection, and the steps from S601 to S606 are executed again; and when the electronic equipment does not carry out continuous monitoring, ending the flow.
Through the steps, the terminal can switch to the idle wireless access component and the channel with the best channel condition monitored by the wireless access component under the condition that the network connection state of the wireless access component in work is not good by configuring the idle wireless access component into the monitoring state, and the seamless switching of a wireless network can be realized only by configuring the idle wireless access component into the monitoring state, so that the resource consumption of the terminal is reduced.
