[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The network switching method, device, electronic device, and storage medium of the embodiments of the present application are described below with reference to the accompanying drawings.

[0029] In the related art, network quality detection is based on signal strength, for example, the received signal strength indication (RSSI), which switches to a network with good network quality when the network quality is poor. However, network roaming also relies on RSSI signals to perform network roaming, which makes weak network switching conflict with roaming scenarios. Therefore, in roaming scenarios, RSSI-based weak network switching is not performed, that is, in network roaming scenarios, weak network switching detection is not performed, so that in the case of network roaming failure, the quality of the access network is poor, resulting in a situation where the Internet cannot be accessed. In order to avoid this situation, the present application proposes a network switching method. In the case of network roaming failure, the attenuation score of the first wireless network currently accessed is reported, so that weak network switching can be performed to ensure network quality.

[0030] Figure 1 A flowchart of a network switching method provided in an embodiment of the present application.

[0031] The executor of the network switching method in the embodiment of the present application is a network switching device, which can be set in an electronic device. The electronic device can be a terminal device or a server. The terminal device is, for example, a smart phone, etc., which is not limited in this embodiment.

[0032] like Figure 1 As shown, the method may include the following steps:

[0033] Step 101: Obtain an attenuation score of a first wireless network to which a terminal device is currently connected.

[0034] In the embodiment of the present application, the attenuation score is determined based on the transmission failure rate of the foreground application running on the terminal device for data transmission, and can represent the data transmission quality of the network transmission layer. Among them, the higher the transmission failure rate, the higher the attenuation score. As an implementation method, the attenuation score is used to update the network score of the current first wireless network of the terminal device, and determine whether to switch the first wireless network currently connected to the terminal device to the second wireless network based on the updated network score, so as to switch the network in the case of poor network signal quality and ensure the smoothness of the network.

[0035] Step 102: Determine whether there is a second wireless network in the environment where the terminal device is currently located.

[0036] The second wireless network and the first wireless network have the same service set identifier (SSID) and different basic service set identifiers (BSSID). BSSID is unique identification information used to identify a wireless base station device, and is used in this application to identify different wireless networks, namely, the first wireless network and the second wireless network. The second wireless network can be one or more.

[0037] In an embodiment of the present application, it is determined whether there is a second wireless network in the environment where the terminal device is currently located. The second wireless network refers to a service set identifier SSID that is the same as the first wireless network, and a basic service set identifier BSSID that is different. That is to say, the first wireless network and the second wireless network belong to a roaming network area, that is, when the terminal device roams between the first wireless network and the second wireless network, it can roam between the first wireless network and the second wireless network without re-entering information.

[0038] Step 103: In response to the existence of the second wireless network, monitoring a network roaming event in which the terminal device switches from the first wireless network to the second wireless network.

[0039] In an embodiment of the present application, when a first wireless network and a second wireless network exist in the environment where the terminal device is currently located, the terminal device may roam, that is, roam from the first wireless network to the second wireless network, and report a roaming event, wherein the network roaming event includes roaming failure and roaming success. Roaming success means that the terminal device roams from the first wireless network to the second wireless network, and when there are multiple second wireless networks, it roams to one of the multiple second wireless networks. Roaming failure means that the terminal device has not roamed from the first wireless network to the second wireless network and is still connected to the first wireless network.

[0040] Step 104, in response to the monitored network roaming event being a roaming failure and the signal strength of the first wireless network being less than a set threshold, within the effective duration corresponding to the network roaming event, reporting the attenuation score of the first wireless network to the connection service of the terminal device.

[0041] As an implementation method, the signal strength of the first wireless network is Received Signal Strength Indication (RSSI), where RSSI is a received signal strength indication, which measures the distance between the signal point and the receiving point by the strength of the received signal, and is used to determine the connection quality, that is, to indicate the signal quality of the currently accessed first wireless network.

[0042] The attenuation score can represent the data transmission quality of the network transmission layer, and is used by the Connectivity Service (CS) to switch the wireless network accessed by the terminal device, such as switching to a weak network in a weak network situation to ensure network quality and avoid the situation where the page cannot be displayed due to poor network quality, that is, the inability to access the Internet. A weak network situation refers to poor network quality, such as an RSSI value less than a set threshold, and the set threshold is, for example, 75dB.

[0043] In the embodiment of the present application, in response to the monitored network roaming event being a roaming failure, that is, the current terminal device fails to roam from the first wireless network to the second wireless network, a roaming failure event (NO AP FOUND) will be reported, and the roaming failure event includes the cause of the roaming failure and the network interface (wlan interace) information. When the terminal device monitors that the network roaming event is a roaming failure, it obtains the current signal strength of the first wireless network. If the signal strength is less than the set threshold, for example, the set threshold is -75db, that is, the RSSI value is less than -75db, it is considered that the current network environment is weak, and the attenuation score of the first wireless network is reported to the connection service of the terminal device within the effective duration of the reported roaming failure. Among them, the connection service obtains the network score of the first wireless network, and the network score is determined based on the signal strength RSSI value and RSSI change rate of the first wireless network. Then, the network score of the first wireless network is subtracted from the corresponding attenuation score to obtain an updated network score, and the wireless network to be accessed by the terminal device is updated according to the updated network score. Among them, in one scenario, there are multiple second wireless networks, and the network scores of multiple second wireless networks are obtained, and at least one third wireless network with a higher network score than the updated network score of the first wireless network is selected from the network scores of the multiple second wireless networks, and the terminal device is switched from the first wireless network to any third wireless network to achieve weak network switching. In another scenario, the signal strength of the first wireless network is less than the set threshold, indicating that the first wireless network is a weak network, that is, the network quality is poor, and there is only one second wireless network, and the updated network score of the first wireless network is lower than the network score of the second wireless network, then the terminal device switches to the second wireless network to achieve weak network switching.

[0044] It should be noted that the terminal device will periodically perform roaming switching in the roaming scenario, so the reported roaming events have an effective duration, for example, the effective duration is 10 seconds. After the effective duration, the roaming event may change. Therefore, it is necessary to report the attenuation score of the first wireless network within the effective duration, so as to determine whether it is a weak network scenario in the event of roaming failure, and perform network switching in a weak network scenario to ensure network quality.

[0045] In the network switching method of the embodiment of the present application, an attenuation score of a first wireless network currently accessed by a terminal device is obtained, and it is determined whether a second wireless network exists in the environment currently located by the terminal device, wherein the second wireless network and the first wireless network have the same service set identifier SSID and different basic service set identifiers BSSIDs. In response to the existence of a second wireless network, a network roaming event of the terminal device roaming from the first wireless network to the second wireless network is monitored. In response to the monitored network roaming event being a roaming failure and the signal strength of the first wireless network being less than a set threshold, within the effective duration corresponding to the network roaming event, the attenuation score of the first wireless network is reported to the connection service of the terminal device, wherein the attenuation score is used for the connection service to perform a weak network switching on the wireless network accessed by the terminal device, thereby achieving a weak network switching in the event of a roaming failure, thereby ensuring network quality.

[0046] Based on the above embodiments, Figure 2 A flowchart of another network switching method provided in an embodiment of the present application is shown as follows: Figure 2 As shown, the method comprises the following steps:

[0047] Step 201: Obtain an attenuation score of a first wireless network to which a terminal device is currently connected.

[0048] For details, please refer to the explanations in the aforementioned embodiments. The principles are the same and will not be repeated here.

[0049] Step 202: Detect the SSID and BSSID of the wireless network in the current environment.

[0050] Step 203: In response to detecting a target wireless network having the same SSID as the first wireless network but a different BSSID, it is determined that a second wireless network exists in the current environment.

[0051] In an embodiment of the present application, the SSID and BSSID of the wireless network in the current environment of the terminal device are detected, and the SSID and BSSID of the first wireless network are compared with other wireless networks respectively to determine whether there is a second wireless network with the same SSID and a different BSSID as the first wireless network.

[0052] Among them, the description of SSID and BSSID can refer to the explanation in the aforementioned embodiment, the principle is the same and will not be repeated here.

[0053] Step 204: In response to the existence of the second wireless network, monitor a network roaming event in which the terminal device roams from the first wireless network to the second wireless network.

[0054] Step 205, in response to the monitored network roaming event being a roaming failure and the signal strength of the first wireless network being less than a set threshold, within the effective duration corresponding to the network roaming event, reporting the attenuation score of the first wireless network to the connection service of the terminal device.

[0055] Among them, step 204 and step 205 can refer to the explanation in the above-mentioned embodiment, and the principles are the same, which will not be repeated here.

[0056] Step 206: In response to the monitored network roaming event being a roaming success, or the network roaming event being a roaming failure, and the signal strength of the first wireless network being greater than or equal to a set threshold, prohibiting reporting the attenuation score of the first wireless network to the connection service.

[0057] In one scenario of an embodiment of the present application, in response to a monitored network switching event being a successful switch, that is, the terminal device roams from a first wireless network to a second wireless network, the attenuation score of the first wireless network is not reported to the connection service, that is, it is prohibited to report the attenuation score of the first wireless network to the connection service.

[0058] In the second scenario of the embodiment of the present application, in response to the network roaming event being a roaming failure and the signal strength of the first wireless network being greater than or equal to a set threshold, it is prohibited to report the attenuation score of the first wireless network to the connection service. This is because although the roaming fails, the first wireless network is not a weak network environment and no network switching is required. The first wireless network can continue to be accessed, thereby avoiding unnecessary network switching and reducing power consumption losses caused by network switching.

[0059] In the network switching method of the embodiment of the present application, in response to the monitored network switching event being a successful roaming, or the network roaming event being a failed roaming, and the signal strength of the first wireless network being greater than or equal to a set threshold, it is prohibited to report the attenuation score of the first wireless network to the connection service. However, when the network roaming event is a successful roaming, and the signal strength of the first wireless network is less than the set threshold, the attenuation score of the first wireless network is reported to the connection service, thereby achieving weak network switching in a roaming scenario, ensuring connection to a wireless network with higher signal quality, and ensuring network quality.

[0060] Based on the above embodiments, the present application provides another network switching method. Figure 3 A flowchart of another network switching method provided in an embodiment of the present application is shown as follows: Figure 3 As shown, the method comprises the following steps:

[0061] Step 301: Obtain an attenuation score of a first wireless network to which a terminal device is currently connected.

[0062] Step 302: Detect the SSID and BSSID of the wireless network in the current environment.

[0063] Step 303: In response to detecting a target wireless network having the same SSID as the first wireless network but a different BSSID, it is determined that a second wireless network exists in the current environment.

[0064] Step 304: monitor a network roaming event in which the terminal device roams from the first wireless network to the second wireless network.

[0065] Step 305, in response to the monitored network roaming event being a roaming failure and the signal strength of the first wireless network being less than a set threshold, within the effective duration corresponding to the network roaming event, reporting the attenuation score of the first wireless network to the connection service of the terminal device.

[0066] Step 306: In response to the monitored network switching event being a roaming success, or the network roaming event being a roaming failure and the signal strength of the first wireless network being greater than or equal to a set threshold, prohibiting reporting of the attenuation score of the first wireless network to the connection service.

[0067] Among them, steps 301 to 306 can refer to the explanations in the aforementioned embodiments, and the principles are the same, so they will not be repeated here.

[0068] Step 307: In response to not detecting a target wireless network having the same SSID as the first wireless network and a different BSSID, determining that no second wireless network exists in the current environment.

[0069] Step 308: Report the attenuation score of the first wireless network to the connection service.

[0070] In an embodiment of the present application, in response to not detecting a target wireless network with the same SSID as the first wireless network and a different BSSID, it is determined that there is no second wireless network in the current environment, that is, the terminal device does not perform network roaming, then the attenuation score of the first wireless network is reported to the connection service, so that the connection service performs weak network switching of the terminal device according to the attenuation score to ensure network quality.

[0071] In the network switching method of the embodiment of the present application, in the scenario of network roaming, in the case of roaming failure, by reporting the attenuation score of the first network, the signal quality detection of the first wireless network accessed by the terminal device is realized, so as to perform weak network switching and ensure network quality. In response to not detecting a target wireless network with the same SSID as the first wireless network and a different BSSID, it is determined that there is no second wireless network in the current environment, that is, the terminal device does not perform network roaming, and then the attenuation score of the first wireless network is reported to the connection service, so that the connection service performs weak network switching of the terminal device according to the attenuation score to ensure network quality.

[0072] Based on the above embodiments, the present application provides another network switching method. Figure 4 A flowchart of another network switching method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the following steps are included before step 101:

[0073] Step 401, obtaining transmission control protocol connection information of a terminal device.

[0074] The transmission control protocol, for example, is Transmission Control Protocol (TCP), and the connection information is TCP parameter information.

[0075] Step 402: Determine the transmission failure rate of data transmission performed by the foreground application running on the terminal device according to the transmission control protocol connection information.

[0076] Among them, foreground applications include news applications, instant messaging applications, video live broadcast applications, etc., which are not listed here one by one.

[0077] An implementation method of an embodiment of the present application obtains parameter information of transmission control protocol connection information, wherein the parameter information includes the number of retransmitted data packets, the number of lost data packets, the number of unacknowledged data packets and the total number of transmitted data packets within a set time length, and determines the transmission failure rate based on the parameter information. Specifically, the transmission failure rate is determined by dividing the sum of the number of retransmitted data packets, the number of lost data packets, and the number of unacknowledged data packets within the set time length by the sum of the number of retransmitted data packets and the total number of transmitted data packets within the set time length.

[0078] Step 403: Determine the attenuation score of the first wireless network according to the transmission failure rate.

[0079] In the embodiment of the present application, the fading score of the first wireless network is determined according to the transmission failure rate, and the fading score can represent the data transmission quality of the network transmission layer. The transmission layer is the data transmission between the wireless access point and the wireless network. Through the transmission layer, it can directly reflect whether the foreground application running on the terminal is stuck.

[0080] In the network switching method of the embodiment of the present application, the attenuation score of the first wireless network can be determined according to the transmission failure rate, that is, the data packet transmission situation of the transmission layer is obtained, and then the actual network status of the foreground application running on the terminal device is perceived, so that in the event of network roaming failure, the network can be switched based on the attenuation score, thereby ensuring the network quality and improving the user experience of using the network. In the weak signal roaming scenario, the network switching sensitivity of the application using TCP connection is improved, and the network can be switched in time when roaming fails, thereby ensuring the network quality.

[0081] In order to implement the above embodiment, the embodiment of the present application also proposes a network switching device.

[0091] The reporting module 54 is further configured to report the attenuation score of the first wireless network to a connection service in response to the absence of the second wireless network.

[0092] In one implementation of the embodiment of the present application, the device further includes:

[0100] The transmission failure rate is determined according to the parameter information.

[0101] It should be noted that the above explanation of the method embodiment is also applicable to the device of this embodiment, and will not be repeated here.

[0102] In the network switching device of the embodiment of the present application, an attenuation score of a first wireless network currently accessed by a terminal device is obtained, and it is determined whether a second wireless network exists in the environment currently located by the terminal device, wherein the second wireless network and the first wireless network have the same service set identifier SSID and different basic service set identifiers BSSIDs. In response to the existence of a second wireless network, a network roaming event of the terminal device roaming from the first wireless network to the second wireless network is monitored. In response to the monitored network roaming event being a roaming failure and the signal strength of the first wireless network being less than a set threshold, within the effective duration corresponding to the network roaming event, the attenuation score of the first wireless network is reported to the connection service of the terminal device, wherein the attenuation score is used for the connection service to perform a weak network switching on the wireless network accessed by the terminal device, thereby achieving a weak network switching in the event of a roaming failure to ensure network quality.
