Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

The character "/" generally indicates that the contextual objects are an "or" relationship.

The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first target object, the second target object, etc. are used to distinguish different target objects, rather than describing a specific order of the target objects.

Reference to "one embodiment" or "some embodiments" or the like in the specification of the present application means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in other embodiments," etc. in various places in this specification are not necessarily All refer to the same embodiment, but mean "one or more but not all embodiments" unless specifically stated otherwise. The terms "including", "comprising", "having" and variations thereof mean "including but not limited to", unless specifically stated otherwise.

In the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

In the embodiment of the present application, the electronic device can establish a network channel with other electronic devices through a wireless network card, and at the same time, the electronic device can also establish a network channel with other electronic devices through a data service network card. Wherein, the network channel established between the wireless network card and other electronic devices may be called a Wi-Fi network, and the network channel established between the data service network card and other electronic devices may be called a cellular network. In practical applications, different applications (or different types of applications) have different requirements on the quality of the used network channels.

In addition, the electronic device may be configured with a network acceleration module, and the network acceleration module is used to perform a network switching operation if a network freeze occurs when the electronic device is running an application program. Specifically, switching between a Wi-Fi network and a cellular network can be realized through the network acceleration module in this embodiment of the present application, please refer to FIG. 1 for details. It can be seen from Figure 1 that during the running of the application program in the electronic device, if it is determined that the Wi-Fi network currently connected to the electronic device is stuck, the network of the electronic device can be switched from the Wi-Fi network to the cellular network .

Referring to FIG. 2 , the user uses application A in the mobile phone to watch video/live broadcast, wherein application A in the mobile phone establishes a network connection with server A of application A through the wireless network card in the mobile phone. The data stream A generated between the application A and the server A (for example, the data stream generated during the live broadcast) is transmitted through the Wi-Fi network between the wireless network card on the mobile phone and the wireless router. The user uses the application B (browsing application) in the mobile phone to chat, and the application B in the mobile phone establishes a network connection with the server B of the application B through the wireless network card of the mobile phone. In addition, the data flow B generated between the application B and the server B (for example, the data flow generated when browsing a website) is transmitted through the Wi-Fi network between the wireless network card on the mobile phone and the wireless router.

In the embodiment of the present application, the data sequence transmitted between two electronic devices is recorded as a data stream. In practical applications, the data stream may be a video stream, an audio stream, a download stream, a session stream, and the like.

If the user uses application A and application B in the mobile phone at the same location (the distance between the wireless network card and the wireless router is the same) and within the same time range (for example, within half an hour), the theoretical Wi-Fi communication quality Little difference. However, since the data flow A generates a larger amount of data per unit time than the data flow B, the data flow A has higher requirements on the quality of the Wi-Fi network than the data flow B. It is relatively smooth for the user to use application B. However, there may be a freeze phenomenon when the user uses application A, resulting in a poor user experience.

In addition, since different business scenarios of the same application process different services, different business scenarios of the same application may have different communication quality requirements. As shown in FIG. 3 , application A may include two scenarios, which may be a live broadcast service scenario and a video scenario respectively. The data stream generated by application A in the live broadcast service scenario may be live stream A1, and the data stream generated by application A in the video scene may be video stream A2. Both the live stream A1 and the video stream A2 can be transmitted through the Wi-Fi network between the wireless network card and the 2.4GHz wireless router.

If the user is at the same location (the distance between the wireless network card and the wireless router is the same) and within the same time range (for example, within half an hour), the user uses application A in the mobile phone to perform live broadcast and video respectively, in theory, the difference in network channel quality is not the same. big. However, since the live stream A1 generates a larger amount of data per unit time than the video stream A2, the live stream A1 has higher requirements on the quality of the network channel than the data stream B. The user uses App A to watch the video smoothly. However, the user may feel that the network speed is too slow when using App A for live broadcast, resulting in a poor user experience.

To sum up, it can be known that different application programs of the same electronic device have different requirements on the quality of the network channel, and different business scenarios of the same application may also have different requirements on the quality of the network channel. When it is determined that the network channel currently used by an application is not enough to carry the data flow generated by the application, the communication quality can be improved by switching the network.

Referring to FIG. 4 , when it is determined that the transmission quality of the data stream A of the application A is poor, the data stream A may be switched from the current Wi-Fi network to another network channel. As shown in FIG. 4 , the mobile phone can switch the data stream A to the cellular network between the data service network card of the mobile phone and the base station, so as to transmit the data stream A with the server A through the cellular network.

In the embodiment of the present application, whether the communication quality of a certain network channel is good (excellent) or bad (poor) or the transmission quality of a certain data stream on a certain network channel is good (good) or bad (poor) can be determined by some parameters judge. During specific implementation, some conditions may be set, for example, when the preset conditions are satisfied, the communication quality is considered good (excellent), and when the preset conditions are not satisfied, the communication quality is considered bad (poor).

From the above introduction, it can be seen that the premise of performing network switching is that the communication quality of the network channel cannot meet the normal communication of the application program, so how to determine whether the evaluation index of the current application program (business scenario) meets the switching conditions is very important.

At present, when determining whether to perform a network switching operation, it is mainly performed on the basis of key streams. However, in order to ensure data security, most of the data streams exchanged between electronic devices and servers are encrypted, such as encrypted by HTTPS. However, this will make it difficult to judge the communication quality of the network from the perspective of key flows when judging whether to perform the network switching operation.

Moreover, when existing electronic devices and servers perform data interaction, the transmitted data stream is not limited to a single stream, that is, there may be multiple streams during data transmission, and the existence of multiple data streams makes it impossible to The communication quality of the network is judged from the key flow. For example, the transmission between the short video application program and the server in the live broadcast business scenario includes both TCP ((Transmission Control Protocol, Transmission Control Protocol) flow and UDP (User Datagram Protocol, User Datagram Protocol) flow, and mixed with P2P (Peer-to-peer, peer-to-peer network) stream transmission.

In addition, when determining whether to perform the network switching operation, it can also be realized by judging the network channel. However, only the parameters of the physical layer or MAC (Medium Access Control) layer are generally used to judge the communication quality only through the network channel. Moreover, when judging whether to perform network switching operations through the channel, different evaluation indicators cannot be used for different scenarios, that is, different scenarios cannot be distinguished. Through the above introduction, we can know the requirements of different scenarios of the same application on the communication quality of the network may be different. For example, the live broadcast service scenario of application A has certain requirements on the rate, while the game scene has low requirements on the rate, but the live broadcast service scenario has higher requirements on delay and packet loss.

Therefore, the existing method for judging network handover cannot accurately judge different application programs and different service scenarios, which leads to a low accuracy rate of network handover.

In order to solve the above problem, an embodiment of the present application provides a network switching method. In the network switching method, developers can pre-configure different evaluation indicators and their corresponding thresholds for different application programs. In addition, different evaluation indicators and thresholds can also be set for different scenarios of the same application. In this way, the accuracy of network switching can be improved to a certain extent.

The network switching method in the embodiment of the present application can be applied to electronic equipment. The electronic device is suitable for mobile phones in the above scenarios. In addition, the electronic device may also be a tablet computer, a notebook, a wearable device, a notebook computer, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a netbook, a personal digital assistant (personal digital assistant, PDA), and the like. The embodiment of the present application does not limit the specific type of the electronic device.

The embodiment of the present application does not specifically limit the specific structure of the execution subject of a network switching method, as long as the code of a network switching method in the embodiment of the Just switch the method for processing.

As an example, application A is installed in the electronic device, and the application may be a short video application.

FIG. 6 is a block diagram of the software structure of the electronic device 100 according to the embodiment of the present application. It can be seen from Figure 6 that the technical architecture of electronic equipment divides the software into several layers, and each layer has a clear role and division of labor. Layers communicate through software interfaces.

The application layer may include various applications, for example, short video applications and browser applications as mentioned above. In addition, the application program can also include applications such as camera, gallery, calendar, call, map, navigation, WLAN, Bluetooth, music, and short message. In addition, the application layer may also be referred to as an application program layer.

The service layer may include environment detection components, network detection components, channel-level path management components, application-level policy management components, channel and application quality assessment components, and network connection management components.

Among them, the environment detection component is used to detect various events of the upper-layer application. As an example, it can detect the opening and exit of the application, the application that is currently switched to the foreground, and the installation and uninstallation of the application.

The network detection component is used to detect the status (on or off, etc.) of the Wi-Fi network supported by the electronic device, and can also detect the status of the data service network supported by the electronic device. As an example, a wireless network card 1 with a frequency band of 2.4 GHz and a wireless network card 2 with a frequency band of 5.0 GHz are set in the electronic device. The network detection component can detect whether the wireless network in the 2.4GHz frequency band is on or off; it can also detect whether the wireless network in the 5.0GHz frequency band is on or off. The electronic device is provided with a data service network card 1 of operator A and a data service network card 2 of operator B. The network detection component can detect whether the data service of operator A is on or off; it can also detect whether the data service of operator B is on or off.

Channel and application quality assessment components are used to assess the quality of network channels. As an example, the channel and application quality evaluation component can evaluate the quality of the Wi-Fi network in the 2.4GHz frequency band, and can also evaluate the quality of the Wi-Fi network in the 5.0GHz frequency band. The quality of operator A's cellular network can also be evaluated, and the quality of operator B's cellular network can also be evaluated.

The network connection management component is used to start a network channel, that is, to convert the network channel from a dormant state to an awakened state. Among them, the network channel in the wake-up state can be used directly.

The channel-level path management component stores the paths of multiple network channels, and is used to request or close any network channel, and can sense the status change of any network channel, and can also perceive the quality of any network channel.

The application-level policy management component is used to enable the network acceleration function and enable the monitoring function of data flow.

The policy layer may include a flow-level policy management component, a flow-level path management component, and a traffic awareness component.

Wherein, the traffic sensing component can be used to count the reported data streams, and can also judge the communication quality of each data stream when receiving the data streams transmitted by the traffic reporting component. The flow-level policy management component instructs the policy enforcement component to perform network switching operations. The flow-level path management component is used to update the selection of network channels according to the policy changes of the upper layer, trigger network channel quality detection, and dynamically select the optimal channel. It can also be used to store the paths of different network channels. For example, it can store the current The path of the used network channel (for example, the primary network channel) and the backup network channel. In addition, the flow-level path management component may also judge the communication quality of each data flow when receiving the data flow transmitted by the flow-level perception component.

The kernel layer includes policy enforcement components and traffic reporting components. Wherein, the traffic reporting component is used to collect data flow information and report the collected data flow information. The policy enforcement component is used to perform network channel switching.

As another embodiment of the present application, one component in the above embodiment may be split into two or more components, and two or more components at the same level may be merged into the same component.

As an example, the flow-level policy management component and the flow-level path management component of the policy layer can be combined into the same component; the application-level policy management component and the channel-level path management component can be combined into the same component. In addition, in the embodiment of the present application, judging whether the application program currently running on the electronic device meets the conditions for network switching can be run in the stream-level path management component, or in the traffic awareness component. The following embodiments will describe in detail under what circumstances to switch the network.

In the embodiment of the present application, when it is detected that the electronic device is running the target application program, multiple evaluation indicators corresponding to the target application program may be obtained, and then, based on these evaluation indicators, it is comprehensively determined whether to perform the network switching operation. Moreover, different application programs run by electronic devices have different corresponding evaluation indicators, so that the accuracy of network switching can be improved to a certain extent.

As shown in FIG. 7 , a network switching method provided by an embodiment of the present application may include the following steps S10 to S12.

Step S01: The flow-level path management component obtains the target data flow of the target application.

It should be noted that obtaining may refer to receiving the target data flow reported by the flow reporting component. As a manner, the flow reporting component may report the data flow related to application A to the flow-level path management component once every preset period, and the data flow may be used as the target data flow. For example, the flow reporting component may report the collected data flow to the flow-level path management component every 500 ms. That is to say, the above-mentioned target data flow may be the data flow of the current cycle.

In the embodiment of the present application, when the stream-level path management component detects that the electronic device is running the target application program, it can acquire the target data stream corresponding to the target application program. In addition, if the target application includes multiple business scenarios, the target data flow of the currently running business scenario can be obtained.

In addition, the target data stream may be composed of multiple consecutive data packets, wherein the multiple data packets may be data about the target application program collected by the traffic reporting component at different times, that is, the target data stream may be the Data generated by the server during network communication. Among them, each packet can be regarded as a window. Additionally, each data packet may include values for multiple evaluation metrics.

As an example, when the user starts application A or switches application A from the background to the foreground, the application-level policy management component can instruct the traffic reporting component to start monitoring application A, that is, instruct the traffic reporting component to report the data flow of application A to the flow level Path management component. Wherein, the application A may be any application program in the electronic device that can be connected to the network.

Step S02: The flow-level path management component selects values corresponding to multiple evaluation indicators from the target data stream, and performs window statistics on the value of each evaluation indicator.

In the embodiment of this application, each application program can store multiple corresponding evaluation indicators. After the stream-level path management component obtains the target data stream transmitted by the traffic reporting component, it can select multiple evaluation indicators from the target data stream. The evaluation value corresponding to the indicator.

An application can correspond to only one business scenario. For example, navigation and travel application A only corresponds to one business scenario of searching routes. In addition, an application can also correspond to multiple business scenarios. For example, short video application B corresponds to a live broadcast business scenario and a video viewing business scenario.

In order to implement network switching more accurately, the embodiment of the present application configures multiple evaluation indicators for each application program and each service scenario corresponding to each application program. In addition, this application also configures a corresponding threshold for each evaluation index. Therefore, the corresponding evaluation indicators may be different for different applications. Moreover, the thresholds of the same evaluation index corresponding to different application programs may also be different.

To sum up, there may be a certain correspondence between the application program, the business scenario corresponding to the application program, the evaluation index, and the threshold corresponding to the evaluation index. In order to better understand the relationship among applications, business scenarios, evaluation indicators, and thresholds corresponding to the evaluation indicators, the embodiment of the present application provides the following Table 1.

Wherein, Table 1 may be stored in the stream-level path management component. When detecting that the electronic device is running the target application, the stream-level path management component may use the Table 1 to obtain multiple evaluation indicators corresponding to the target application.

It can be seen from Table 1 that the same application (business scenario) can have multiple evaluation indicators, and the corresponding evaluation indicators may be different for different applications.

As an example, the evaluation indicators corresponding to the live broadcast business scenario in the "Huya" application can be TCPRTT (Round Trip Time, round-trip transmission time), TCP downlink rate, TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate.

As another example, the evaluation indicators corresponding to the business scenario of browsing websites in the "browser" application program may be TCP RTT, TCP uplink retransmission rate, TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate.

In addition, it is known from Table 1 that there may be one or more thresholds corresponding to the same evaluation indicator. For example, there is only one threshold for the evaluation indicators TCP RTT and TCP downlink retransmission rate of the application "Huya", that is, only threshold 1. For another example, there may be two thresholds corresponding to the evaluation index downlink rate (TCP+UDP) and the uplink retransmission rate of the WiFi MAC layer, that is, threshold 1 and threshold 2.

It should be noted that, when configuring evaluation indicators for each application program (business scenario), in the embodiment of the present application, one or more evaluation indicators such as TCP RTT, downlink rate, uplink rate, and retransmission rate may be selected. Wherein, the retransmission rate may include a TCP downlink retransmission rate, a TCP uplink retransmission rate, and a WiFi MAC layer uplink retransmission rate.

Table 1 Evaluation indicators and thresholds for multiple applications and multiple business scenarios

In addition, the rate may include an uplink rate and a downlink rate, and the downlink rate may include a TCP downlink rate, a UDP downlink rate, a TCP+UDP downlink rate, and the like. Optionally, delay, packet loss rate, and whether there is a response can also be configured as evaluation indicators. The specific evaluation indicators configured for the application or business scenario are not specifically limited here, and can be selected according to the actual situation.

The above Table 1 only lists some applications and the evaluation indicators and thresholds of the scenarios corresponding to the applications, and is only used as an example.

It is known from the above introduction that the target data stream may include multiple data packets, each data packet corresponds to a window, and each window may include values of multiple evaluation indicators, in order to better evaluate the application A. After obtaining multiple evaluation indicators, the flow-level path management component can perform window statistics on multiple values corresponding to each evaluation indicator, so as to obtain the target value corresponding to each evaluation indicator.

In the embodiment of the present application, the window statistics may be to perform statistics on multiple values corresponding to the same evaluation indicator. As an example, window statistics may be obtained by obtaining an average of multiple evaluation values corresponding to the same evaluation index, and using the obtained average value as a target value of the evaluation index.

As another example, the window statistics may also be to obtain the maximum value among multiple evaluation values corresponding to the same evaluation index, and use the maximum value as the target value of the evaluation index. There is no specific restriction on which statistical strategy to adopt here, and it can be selected according to the actual situation.

As a way, when performing window statistics on the evaluation index, the flow-level path management component may only perform one window statistics operation, or may also perform multiple window statistics operations. Moreover, when performing multiple window statistical operations, the number of windows may also be different.

As an example, two window statistics may be performed when performing statistics on the downlink rate (TCP+UDP) of the evaluation index. Wherein, performing window statistics for the first time may be to obtain the average value of 4 windows to obtain the first target value; performing window statistics for the second time is to obtain the average value of 7 windows to obtain the second target value.

From Table 1, we know that the evaluation indicators corresponding to the live broadcast business scenario of "Huya" include TCP RTT, downlink rate (TCP+UDP), TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate. In this application, the TCP RTT can be recorded as R, the downlink rate as V, the TCP downlink retransmission rate as P, and the WiFi MAC layer uplink retransmission rate as C.

After obtaining multiple evaluation indicators, the flow-level path management component can select the 4 data packets closest to the current moment from the target data flow for window statistics. These 4 data packets are data packet 1, data packet 2, data packet Packet 3 and Data Packet 4. In addition, the evaluation indicators included in data package 1 are R1, V1, P1 and C1; the evaluation indicators included in data package 2 are R2, V2, P2 and C2; the evaluation indicators included in data package 3 are R3, V3, P3 and C3; The evaluation indicators included in data package 4 are R4, V4, P4 and C4.

After obtaining 4 data packets, the flow-level path management component can perform window statistics on each evaluation indicator in these data packets. For example, calculate the average value of the TCP downlink retransmission rate in 4 data packets to obtain the target value of the TCP downlink retransmission rate. The specific calculation formula can be: (P1+P2+P3+P4)/4, the statistics of other evaluation indicators are similar to the statistics of the TCP downlink retransmission rate and will not be repeated here.

In addition, when performing window statistics on the value of each evaluation index, the same statistical method may be used, or different statistical methods may be used. For example, the average value is calculated when the value of each evaluation index is counted. For another example, when performing statistics on the values of some evaluation indicators, it may be to calculate the average value, and another part may be to obtain the maximum value/minimum value, etc.

To sum up, by performing window statistics on the values of multiple evaluation indicators, the target value corresponding to each evaluation indicator can be obtained, and then it can be determined whether to perform a network switching operation based on these target values. In addition, after obtaining the target value corresponding to each evaluation index, the flow-level path management component may select one of the evaluation indexes as the current index, that is, enter step S03.

It should be noted that the value of the evaluation indicator in the target data flow may be obtained by the flow-level path management component from the flow reporting component. For example, values such as TCP RTT, TCP downlink rate, and TCP downlink retransmission rate. Optionally, the value of the evaluation indicator may also be obtained by the flow-level path management component from the service layer. For example, the value of the uplink retransmission rate of the WiFi MAC layer. There is no specific restriction on which component transmits the flow to the stage path management component for each evaluation index, and it can be selected according to the actual situation of the application program and the scenario corresponding to the application program.

Step S03: The flow-level path management component selects one of multiple evaluation indicators as the current indicator.

In some implementation manners, the flow-level path management component may sequentially select a current indicator from multiple evaluation indicators, and then determine whether the current indicator satisfies the voting condition. Specifically, the stream-level path management component may determine whether the current index exceeds a corresponding threshold, that is, enter step S04.

Step S04: the flow-level path management component determines whether the target value of the current index exceeds the corresponding threshold.

As a manner, when the current index is acquired, the flow-level path management component can determine whether the target value of the current index exceeds the threshold. If it exceeds the threshold, set the voting mark of the current indicator, that is, enter step S05. Wherein, the threshold may be the maximum/minimum value corresponding to the current indicator.

In addition, when it is determined that the current index does not exceed the threshold, the flow-level path management component may determine whether the current index has voted, that is, enter step S10.

As an example, if the current index is the TCP downlink retransmission rate, it is determined whether the target value P0 of the TCP downlink retransmission rate is greater than the threshold (20%) corresponding to the TCP downlink retransmission rate. If the target value P0 of the TCP downlink retransmission rate is greater than the threshold, a voting mark for the current target TCP downlink retransmission rate may be set. Among them, the voting mark is used to indicate that the current indicator TCP downlink retransmission rate has exceeded the threshold.

Step S05: The flow-level path management component sets the voting mark of the current indicator.

In this embodiment of the application, when it is determined that the target value of the current index exceeds the threshold, the flow-level path management component may set the voting mark of the current index, wherein setting the voting mark of the current index may be setting the voting mark for the current evaluation index.

As an example, if it is determined that the current TCP downlink retransmission rate exceeds its corresponding threshold, the voting mark corresponding to the TCP downlink retransmission rate may be set to 1, where 1 is used to indicate that 1 vote has been cast.

It should be noted that, when the flow-level path management component determines whether the target value of the current index exceeds the corresponding threshold, it may first determine whether there is only one threshold for the current index. If there is only one threshold, it is determined whether the target value of the current indicator exceeds the threshold.

In addition, if it is determined that there are multiple thresholds for the current index, the flow-level path management component can first determine whether the first target value of the current index exceeds the threshold 1, and if it exceeds the threshold 1, set a voting mark for the current index, and the voting mark at this time is 1. On this basis, continue to determine whether the second target value of the current indicator exceeds the threshold 2, and if it exceeds the threshold 2, set the voting mark for the current indicator again, and the voting mark at this time is 2. In other words, if the same evaluation metric is marked twice, it means that there are two votes.

In this embodiment of the present application, the first target value and the second target value may be the same or different. In addition, the number of windows for obtaining the first target value and the number of windows for obtaining the second target value may be the same or different, and the specific selection is not specifically limited here and may be selected according to actual conditions.

As an example, if the first target value of the current index WiFi MAC layer uplink retransmission rate exceeds the threshold 1, the voting mark corresponding to the WiFi MAC layer uplink retransmission rate may be 1. Among them, 1 is used to indicate that 1 vote has been cast. In addition, if the target value of the current indicator WiFi MAC layer uplink retransmission rate is greater than the threshold 2, the ticket mark is set to 2. Among them, 2 is used to indicate that 2 votes have been cast.

Step S06: The flow-level path management component records the voting time of the current index.

In some implementations, after the flow-level path management component sets the voting mark of the current indicator, it can record the voting time of the current indicator. In other words, after the voting operation is performed, the flow-level path management component can record the voting time of the current indicator. For example, after the flow-level path management component sets a voting mark for the current indicator TCP RTT, it can record the time point of voting.

It should be noted that the flow-level path management component can also store the historical voting time of the current index. By comparing the current voting time with the historical voting time, the flow-level path management component can more accurately implement network switching.

Step S07: The flow-level path management component judges whether the votes with voting marks reach two votes.

As a way, after the stream-level path management component records the voting time, it can also determine whether the current number of votes has accumulated two votes, that is, determine whether the current number of votes has reached two votes. Wherein, the two votes may be the case where the same evaluation index casts two votes, or may be the case where two different evaluation indexes cast two votes respectively.

As an example, when the downlink rate (TCP+UDP) or the uplink retransmission rate of the WiFi MAC layer meets the threshold 2 corresponding to the respective evaluation indicators, it is determined that the current vote has accumulated two votes, that is, the downlink rate (TCP+UDP) vote is marked as 2, or the vote mark of the uplink retransmission rate of the WiFi MAC layer is 2, then it is determined that the current vote has accumulated two votes.

As another example, the vote for TCP RTT is marked as 1, the vote for the downlink rate (TCP+UDP) is marked as 1, and it is determined that the current vote has accumulated two votes; the vote for TCP RTT is marked as 1, and the vote for TCP downlink retransmission rate is marked as 1. Confirm that the current vote has accumulated two votes; the vote for TCP RTT is marked as 1, the vote for the uplink retransmission rate of the WiFi MAC layer is marked as 1, and the current vote has accumulated two votes; the vote for the downlink rate (TCP+UDP) is marked as 1, The vote for the TCP downlink retransmission rate is marked as 1, and the current vote has accumulated two votes; the vote for the downlink rate (TCP+UDP) is marked as 1, and the vote for the WiFi MAC layer uplink retransmission rate is marked as 1, and the current vote has accumulated two votes ; The vote for the TCP downlink retransmission rate is marked as 1, and the vote for the WiFi MAC layer uplink retransmission rate is marked as 1, and it is determined that the current vote has accumulated two votes.

From the above introduction, we can know that there can be multiple evaluation indicators corresponding to each application/business scenario, and the voting methods can also be different, so the above evaluation indicators and voting methods are only examples, and the actual situation shall prevail.

In some other implementation manners, when the flow-level path management component determines that the current voting has accumulated two votes, it may determine that the communication quality of the network is "stuck", that is, enter step S08. In addition, if the current number of votes does not reach two votes, it may be determined whether each evaluation index has been traversed, that is, enter step S09.

It should be noted that when determining whether to perform network switching operations, different applications (business scenarios) can have the same number of evaluation indicators or different numbers of evaluation indicators. There is no clear limit on how to set it here. You can choose according to the actual situation.

To sum up, different applications (business scenarios) have different requirements on the quality of network channels. The embodiment of the present application can be configured with different evaluation indicators for different applications (business scenarios), and based on these evaluation indicators, it is determined whether the communication quality of the current network is stuck, and if it is stuck, the network switching operation is performed, which to a certain extent It can improve the accuracy of network switching.

Step S08: The flow-level path management component determines that the network is stuck, and determines to switch the network.

As a way, when the stream-level path management component obtains two votes, it can determine that the network communication quality of application A is poor, that is, the network freezes, and at this time, the stream-level path management component determines to switch the network. On this basis, the flow-level path management component can request the backup network from the channel-level path management component, and after obtaining the backup network, transfer the backup network to the policy execution component through the flow-level policy management component, so that the electronic The device's network switches from a Wi-Fi network to a cellular network.

Step S09: the flow-level path management component determines whether each evaluation indicator has been traversed.

As a manner, when it is determined that the current number of votes does not reach two votes, the flow-level path management component may determine whether each evaluation index has been traversed. If it is determined that each evaluation index in the target data flow has been traversed, the flow-level path management component may obtain the data flow of the next cycle, and use the data flow of the next cycle as the target data flow. On this basis, step S02 to step S08 are repeatedly executed.

In addition, if there is an evaluation index that has not been traversed, the next evaluation index is obtained, and the next evaluation index is used as the current index, and continues to determine whether the target value of the current index exceeds the corresponding index threshold.

As an example, there are four evaluation indicators corresponding to the live broadcast business scenario of "Huya". These four evaluation indicators are TCP RTT, downlink rate (TCP+UDP), TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate. After traversing the TCP RTT, the downlink rate (TCP+UDP) and the TCP downlink retransmission rate respectively, the flow-level path management component determines that the uplink retransmission rate of the WiFi MAC layer has not been traversed. At this point, the flow-level path management component may take the uplink retransmission rate of the WiFi MAC layer as a current indicator, and then continue to determine whether the target value of the uplink retransmission rate of the WiFi MAC layer exceeds the corresponding indicator threshold.

As another example, if the flow-level path management component determines that the TCP RTT, downlink rate (TCP+UDP), TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate have all completed traversal, then obtain the data flow of the next cycle, And take it as the target data stream, and repeat the above-mentioned network communication quality judgment operation.

Step S10: The flow-level path management component judges whether the voting mark of the current indicator is empty.

In the embodiment of the present application, when the flow-level path management component determines that the target value of the current indicator does not exceed the corresponding indicator threshold, it may determine whether the voting mark of the current indicator is empty. Among them, the voting mark is empty means that there is no voting for the current indicator. If the voting mark of the current indicator is empty, it is determined whether each evaluation indicator has been traversed, that is, enter step S09. In addition, if the voting mark of the current indicator is not empty, that is, the current indicator has already voted, the flow-level path management component determines whether the voting time of the current indicator has exceeded the specified time, that is, enters step S11.

Step S11: The flow-level path management component determines whether the voting time of the current index has exceeded the specified time.

Through the above introduction, we know that after each vote, the flow-level path management component can record the time of the current index vote, and the flow-level path management component can also store the historical voting time. In order to ensure the accuracy of network switching, after determining that the current indicator has been voted, the flow-level path management component can determine whether the voting time of the indicator has exceeded the specified time. Wherein, the specified duration may be 3 seconds.

If the voting time of the current indicator has exceeded the specified time, the flow-level path management component may remove the voting mark of the current indicator, that is, enter step S12. In addition, if the voting time of the current indicator does not exceed the specified time, the flow-level path management component can determine whether each evaluation indicator has been traversed, that is, enter step S09.

As an example, the flow-level path management component determines that the target value of the current indicator TCP RTT does not exceed the threshold, and determines that the current indicator TCP RTT has voted before. At this point, the flow-level path management component can judge whether the time from the previous voting time to the current time exceeds 3 seconds, and if not, proceed to step S09. If it exceeds 3 seconds, the voting mark of the current indicator can be removed.

It should be noted that the specified duration can include multiple periods, and when different evaluation indicators in each period exceed the corresponding threshold, corresponding voting marks can be set. For example, the specified duration is 3s, including 6 cycles, and the duration of each cycle is 500ms.

Step S12: The flow-level path management component removes the voting mark of the current indicator.

In this embodiment of the present application, removing the voting mark of the current index may be to initialize the voting record of the current index to zero, that is, the flow-level path management component removes the voting mark set before the current index.

As a manner, through the above voting process, the flow-level path management component may obtain a voting result, and the voting result may include: zero votes, one vote, and two votes. After the flow-level path management component obtains the voting result, it can obtain the communication quality of the current network based on the voting result. Specifically, when the voting result is zero votes or one vote, the communication quality of the corresponding network is good (Good); when the voting result is two votes, the corresponding communication quality is bad.

In order to understand the voting process more clearly, the embodiment of this application provides an example diagram as shown in FIG. 8 . From Figure 8, it can be seen that there are four evaluation indicators corresponding to the live broadcast business scenario of "Huya", namely TCP RTT, downlink rate (TCP+UDP), TCP downlink retransmission rate, and WiFi MAC layer uplink retransmission rate.

As a method, the specified duration can include a plurality of cycles, and if different evaluation indicators are provided with voting marks in different cycles within the specified duration, and the number of voting marks exceeds the threshold value, then it is determined that the communication quality of the network is Bad (card pause). A as shown in FIG. 8 is a voting mark generated when the value of the TCP RTT in the first cycle of the first specified time exceeds its corresponding threshold value. B shown in FIG. 8 is a voting mark generated when the value of the downlink rate (TCP+UDP) in the second period of the first specified time exceeds its corresponding threshold value. It can be seen that the voting mark at this time reaches the threshold of two votes, and it is determined that the communication quality of the network is Bad (stuck).

As another way, if only one evaluation indicator is set with a voting mark within a specified time period, it is determined that the communication quality of the network is Good (excellent). C shown in FIG. 8 is a voting mark generated when the value of the downlink rate (TCP+UDP) in the first cycle of the second specified time exceeds its corresponding threshold. It can be seen that the voting mark at this time does not reach the quantity threshold of two votes, and it is determined that the communication quality of the network is Good (excellent).

As another way, if different evaluation indicators are set with voting marks in the same period within a specified period of time, and the number of voting marks exceeds a threshold, it is determined that the communication quality of the network is Bad (stuck). D as shown in FIG. 8 is a voting mark generated when the value of TCPRTT in the first cycle of the third designated time exceeds its corresponding threshold value. E shown in FIG. 8 is a voting mark generated when the value of the downlink rate (TCP+UDP) in the first cycle of the third specified time exceeds its corresponding threshold value. It can be seen that the voting mark at this time reaches the threshold of two votes, and it is determined that the communication quality of the network is Bad (stuck).

As another way, if the same evaluation indicator is set with multiple voting marks in the same period within a specified period of time, and the voting marks exceed the number threshold, it is determined that the communication quality of the network is Bad (stuck). F shown in FIG. 8 is a voting mark generated when the value of the uplink retransmission rate of the WiFi MAC layer in the first period of the fourth specified time exceeds both the corresponding first threshold and the corresponding second threshold. It can be seen that the voting mark at this time reaches the threshold of two votes, and it is determined that the communication quality of the network is Bad (stuck).

In other words, if the uplink retransmission rate of the WiFi MAC layer deteriorates seriously, two votes can be cast directly, and the network communication quality can be determined as Bad (stuck). Specifically, the flow-level path management component can determine whether the value of the uplink retransmission rate of the WiFi MAC layer exceeds its corresponding threshold 2. If it exceeds, it is determined that the uplink retransmission rate of the WiFi MAC layer is seriously deteriorated. At this time, the communication quality of the network is determined to be Bad (Carton).

In order to ensure user experience, when the communication quality of the network is determined to be Bad (stuck), the embodiment of the present application may switch the network of the electronic device from the Wi-Fi network to the cellular network, that is, perform a network switching operation.

It should be noted that, within a specified period of time, if only one of the multiple evaluation indicators casts 1 vote or 0 vote, it is determined that the communication quality of the network is Good. Wherein, the specified time period may be 3s. For example, within 3s, only the TCP downlink retransmission rate casts 1 vote, and at this time it is determined that the communication quality of the network is Good.

To sum up, the evaluation indicators of voting can belong to different periods, as shown in Figure 8 A and B. In addition, different evaluation indicators of voting may also belong to the same period, for example, D and E in Fig. 8 belong to the same period. Moreover, if the same evaluation indicator casts two votes in different periods within a specified time period, it can also be determined that the communication quality of the network is Bad (stuck).

It should be noted that the vote threshold in this embodiment of the application is configurable, and it may be two votes or more than two votes. For example, the vote threshold may also be 3 votes or more. There is no specific limit on how many votes the threshold is set to, and it can be selected according to the actual situation.

In the embodiment of the present application, when the stream-level path management component determines that the communication quality of the network is stuck, it determines to switch the network, that is, switches the current network of the electronic device from the Wi-Fi network to the cellular network.

When performing a network switching operation, the flow-level path management component can determine whether there is a backup network. If there is no backup network, the flow-level path management component can send a backup path request message to the channel-level path management component. Wherein, the standby network may be a cellular network.

As a method, after receiving the request message of the backup path, the channel-level path management component starts to search for other available and best-quality networks other than the currently used active network, and uses the found network as a backup when determining the backup path After the network, the channel-level path management component can send a request to enable the backup network to the network connection management component.

In addition, after receiving the activation request of the standby network, the network connection management component switches the standby network from a sleep state to a wake-up state. On this basis, the network connection management component may send a message that the standby network has been awakened to the channel-level path management component. On this basis, the channel-level path management component can send the backup network to the flow-level path management component.

As a method, after obtaining the standby network, the flow-level path management component can transmit the standby network to the policy enforcement component through the flow-level policy management component, so as to switch the network of the electronic device from the current network to the standby network through the policy enforcement component . Specifically, switch the network of the electronic device from the Wi-Fi network to the cellular network.

In some other implementations, if the flow-level management component determines that there is a backup network, it may no longer request to obtain the path of the backup network, but directly sends the stored backup network to the flow and policy execution component, so that The network of the electronic device is switched to the backup network.

In some other implementation manners, when it is determined to perform the network switching operation, the embodiment of the present application may also output prompt information, so as to remind the user that the current network has been switched from the Wi-Fi network to the cellular network through the prompt information. In order to understand the process of network switching and prompting more clearly, the embodiment of the present application provides example diagrams as shown in FIG. 9a to FIG. 9c. It can be seen from FIG. 9a that multiple application programs can be installed on the electronic device, and these application programs can include a clock, a calendar, a gallery, a browser, and "Huya".

Optionally, when the user clicks on the icon of the application "Huya", it can open the application, and then the display interface of the electronic device can jump from Figure 9a to Figure 9b, Figure 9b is the user's live video interface, The video interface may include controls such as the number of fans of the user, the number of popularity, the time of the live broadcast, and expressions. During this process, the application-level policy management component can instruct the traffic reporting component to start monitoring the data flow of "Huya". In addition, the traffic reporting component can periodically report the monitored data flow to the flow-level path management component in the process of monitoring "Huya".

After the stream-level path management component receives the target data stream related to "Huya" transmitted by the traffic reporting component, it can select the values of multiple evaluation indicators corresponding to "Huya" from the target data stream. On this basis, the flow-level path management component can comprehensively determine whether to perform a network switching operation based on the values of these evaluation indicators. Specifically, if it is determined that the communication quality of the network is stalled, a network switching operation is performed.

In addition, after executing the network switching operation, the policy execution component may output prompt information after switching the network of the electronic device from the Wi-Fi network to the cellular network in order to ensure user experience. Specifically, the policy execution component can return the result of successfully executing the switching operation to the flow-level path management component, and the flow-level path management component can send a display request for prompt information to the service layer, and the view system of the service layer can control the electronic system based on the request. The device displays an interface as shown in Figure 9c.

In other words, after the network switching operation is performed, the embodiment of the present application may output a network switching prompt box as shown in FIG. 9c, through which the user is notified that the electronic device has switched from the wireless network to the cellular network. The prompt information in the embodiment of the present application is only an example, and the electronic device may also output the prompt information through one or more ways of floating window, vibration, or voice.

In another embodiment of the present application, in order to ensure the accuracy of network switching, when the electronic device obtains the path of the backup network, it may also compare the current network with the backup network. When the flow-level path management component in this implementation receives the backup network transmitted by the channel-level path management component, it can determine whether the communication quality of the backup network is better than that of the current network, and if so, perform network switching operations.

In addition, if the communication quality of the current network is better than that of the standby network, it means that the communication quality of the standby network is worse, and even if the current network is relatively poor, there is no need to switch.

In some other implementation manners, the component performing network switching may also be a flow sensing component. Specifically, after the traffic sensing component receives the target data stream of the target application transmitted by the traffic reporting component, it can select the values of multiple evaluation indicators from the target data stream, and then comprehensively determine the Whether the communication network of the electronic device is stuck. If it is determined that the communication quality of the network is stalled, the traffic sensing component may instruct the policy enforcement component to perform a network switching operation.

If there are not multiple services corresponding to the target application, the target data flow may be data corresponding to the target application.
