Method for detecting network quality and related electronic equipment

technical field

The present application relates to the field of network quality detection, in particular to a network quality detection method and related electronic equipment.

Background technique

With the rapid development of electronic technology and Internet technology, mobile devices such as mobile phones are more and more widely used in people's daily life. For example, mobile payment and games can be performed through mobile phones. In order to ensure the normal operation of common services (such as games, calls, social software, etc.), usually the user's mobile phone will be connected to the wireless network. In the case of poor network quality, network acceleration is usually performed. However, in the process of users surfing the Internet, the network quality detection often has inaccurate problems. In the case of inaccurate network quality detection, the problem of network misconnection may occur, which may cause users to use a large amount of data traffic for network acceleration. , when the user's data traffic package is insufficient, the user's package limit may be exceeded, so that the user needs to pay additional phone charges, thereby reducing the user's online experience.

Contents of the invention

The embodiment of the present application provides a network quality detection method, which solves the problem of incorrectly switching network channels during the network acceleration process due to inaccurate network quality detection results.

In the first aspect, the embodiment of the present application provides a method, including: responding to the user's first operation, starting the first application; periodically receiving packet statistical information of the target flow; the packet statistical information is the first application and Statistical information of data flow between servers; when it is judged that the first application is in the state of suspending download/stop downloading based on the packet statistical information of the current period, the network quality of the current period is not recorded; based on the packet statistical information of the current period Determine whether the uplink message is an ACK message; if the uplink message is not an ACK message, record the network quality of the next period. In the above embodiment, it is determined whether the uplink message is an ACK message. If the uplink message is an ACK message, the electronic device detects the network quality according to the original state. For example, when the first application is in the download state, the electronic device The device detects the network quality based on the downlink network rate, and the electronic device does not record the network quality when the download of the first application is suspended/terminated. Through such a method, it can be solved that when the first application is in the state of suspending download/ending download, the electronic device misjudges the uplink message as a download request message, and continues to detect the network quality after the download is completed, resulting in the error of the network quality detection result. The inaccuracy makes the electronic device use the inaccurate network detection result as a reference factor for judging whether to switch the network channel, causing the problem that the electronic device wrongly switches the network channel of the first application.

In a possible implementation manner, the method further includes: if the uplink message is an ACK message, judging whether the uplink message of the next cycle is an ACK message.

In this way, the electronic device can distinguish the uplink message as an ACK message or a download request message, so as to prevent the electronic device from misjudging the uplink message as a download request message when the first application is in the state of suspending download/ending download. Continue to detect the network quality after the download is completed, resulting in inaccurate network quality detection results, so that the electronic device uses this inaccurate network quality detection result as a reference factor for judging whether to switch the network channel, so that the electronic device switches the first application by mistake network channel.

In a possible implementation manner, the network quality is obtained based on the downlink network rate in the packet statistics information of the current period; if the downlink network rate is less than or equal to the preset rate threshold, the network quality of the current period is recorded as poor ; If the downlink network rate is greater than the preset rate threshold, the network quality record of the current cycle is excellent. In this way, the electronic device can judge whether to switch the network channel based on the network quality, so as to prevent the first application from being stuck and reduce the user's online experience.

In this way, the electronic device can judge whether to switch the network channel based on the network quality, so as to prevent the first application from being stuck and reduce the user's online experience.

In this way, it is beneficial for the electronic device to judge whether to record the network quality in the next period.

In a possible implementation manner, when it is judged that the first application is in the state of suspending download/stop downloading based on the packet statistics information of the current period, the network quality of the current period is not recorded, including: packets based on the current period When the statistical information judges that the download end flag is the first flag, the network quality of the current period is not recorded; the download end flag is used to represent the download status of the first application; the first flag is used to represent that the first application is suspended Download/stop download status.

A router 101 is included in the living room of the user, and the router 101 sends out a WIFI signal by connecting to the network, so that the electronic equipment 100, the TV set 103 and the intelligent air conditioner 104 in the living room can be connected to the network through the WIFI signal transmitted by the router 101, and the electronic equipment 100 , the television 103 and the intelligent air conditioner 104 are in the same local area network. FIG. 2 is an example illustrating that the user is currently using the electronic device 100 to connect to the network and watch videos online through WIFI. It is assumed that the coverage of the WIFI signal transmitted by the router 101 is only in the living room, and the network quality of the electronic device 100 after connecting to WIFI varies. It becomes worse as the distance between the electronic device 100 and the router 101 increases.

Next, in combination with Figure 3A-Figure 3F , the application scenario of electronic equipment performing network channel switching due to the deterioration of network quality during the process of users watching videos online will be introduced. Figure 3A-Figure 3F is a group of users provided by the embodiment of this application An exemplary interface for watching videos online using the electronic device 100 .

3A is the user interface 10 of the electronic device 100, which includes a WIFI network icon 301, a mobile data icon 302, a video application icon 303, a network speed display icon 304 and other application icons. Among them, the WIFI network icon 301 is used to indicate that the electronic device 100 has been connected to the WIFI network channel, and the mobile data icon 302 is used to indicate that the electronic device 100 has been connected to the mobile data network channel. It is assumed that the electronic device 100 has a primary SIM card and a secondary SIM card and These two SIM cards have both started the mobile data service. It can be seen from FIG. 3A that the electronic device 100 is currently connected to the WIFI network channel, the primary mobile data network channel (the network channel corresponding to the primary SIM card) and the secondary mobile data network channel (the secondary SIM card). network channel corresponding to the card). In the embodiment of the present application, the electronic device 100 uses the WIFI network channel as the main network channel, and the network channel currently enabled by the electronic device 100 is the main network channel as an example for description. The network speed display icon 304 is used to display the downlink rate of the currently enabled network channel. For example, as shown in FIG. 3A , the downlink rate of the current WIFI network channel is 1.4M/S. After the electronic device 100 detects a click input operation on the video application icon 303, in response to the input operation, the electronic device 100 displays the user interface 20 as shown in FIG. 3B.

As shown in Figure 3B, the user interface 20 is the main interface of the video application, including a video recommendation area 310. The video cover 311 currently displayed in the video recommendation area is "Pet Story". After the click input operation, the electronic device 100 displays the user interface 30 as shown in FIG. 3C.

As shown in Figure 3C, the user interface 30 is an interface for playing video. As can be seen from Figure 3C, the network channel currently enabled by the electronic device 100 is the main network channel (assuming that the main network channel is a WIFI network channel), and the current network speed is 1.8M/ s, the playback progress of the current video is 05:48.

As shown in Figure 3D, during the video watching process, the user carries the electronic device 100 and moves from activity area 1 to activity area 2, and then moves from activity area 2 to activity area 3 to turn on the air conditioner, and activity area 1, activity area 2, The distance between the active area 3 and the router 101 decreases successively. When the user moves to the active area 2, the electronic device 100 displays a user interface 40 as shown in FIG. 3E.

As shown in FIG. 3E , the user interface 40 is a video playback interface, the current network channel enabled by the electronic device 100 is the main network channel, the current network speed is 512k/s, and the current video playback progress is 06:48. It can be seen from FIG. 3E that because the network quality of the electronic device 100 in the active area 2 is worse than that in the active area 1, the network speed of the electronic device 100 is lower than that in the active area 1. When the user moves to After the area 3 is activated, the electronic device 100 displays the user interface 50 as shown in FIG. 3F .

As shown in FIG. 3F , the user interface 50 is a video playback interface, and the video playback interface includes a network acceleration prompt box 501 , and the network acceleration prompt box 501 is used to prompt that the network acceleration of the video application has been enabled. For example, the network acceleration prompt box 501 in FIG. 3F displays the information of "the switching of the network channel has been completed, and the network acceleration is performed". It can be seen in the user interface 50 that the network channel enabled by the current video application is a backup network channel, the current network speed is 1.8M/s, and the playback progress of the current video is 06:48. The electronic device 100 completes the switching from the main network channel to the standby network, and compared with the network rate in the active area 2, after the electronic device switches to the standby network channel in the active area 3, the network rate is greatly improved.

It should be understood that the above-mentioned Figures 3A-3F show that during the process of playing video on the electronic device, the network quality changes due to the change of the straight-line distance between the electronic device and the router, and the electronic device is based on the detected network quality. A set of exemplary user interfaces for network channel switching shall not limit this embodiment of the present application.

The foregoing FIGS. 2-3F introduce application scenarios in which electronic devices perform network quality detection. In the above-mentioned embodiment, when the user moves from active area 1 to active area 2, and then from active area 2 to active area 3, the network quality deteriorates due to the continuous increase of the linear distance between the electronic device and the router. The network speed of electronic devices is continuously reduced. When the network rate of the electronic device drops to a certain threshold, the electronic device will switch the network channel (for example, switch from the WIFI network channel to the main mobile data network channel), and the network quality after the switch is compared with the network quality before the switch better.

Below, the principle of the electronic device network quality detection method is introduced in conjunction with the accompanying drawings. As shown in Figure 4, the electronic device transmits data streams with the server through the WIFI network channel, and the WIFI network channel includes multiple stream channels (in the figure Only two flow channels are listed), wherein, flow channel A is used to transmit the upstream data flow from the application 1 to the server, and flow channel B is used to transmit the downstream data flow from the server to the application 1. After application 1 sends an uplink message to the server through stream channel 1, the electronic device starts to detect the network quality of the downlink data flow (for example, the transmission rate of the downlink datagram, the delay of the datagram, the packet loss rate, etc.), and the When the network quality of the data flow deteriorates, the data flow between the application 1 and the server is switched to the mobile data network channel for transmission.

Application 1 and the server usually use the UDP protocol to transmit messages. Application 1 first sends an uplink download request message to the server for communication with the server. When the server receives the uplink download request message, it will send a downlink data stream to application 1. , at this time, the electronic device will be triggered to perform message detection on the downlink data flow, thereby detecting the network quality of the current data flow, and judging whether to switch the network channel according to the network quality. After the server sends the downlink data stream, the electronic device no longer performs network quality detection, network channel switching and other related operations.

However, as shown in FIG. 5 , when application 1 transmits an uplink message using a protocol such as GQUIC, after application 1 sends an uplink download request message to the server, the server sends a downlink data stream to application 1. When the server sends downlink data to application 1, application 1 may send uplink ACK and other confirmation messages to the server. This kind of confirmation message is only used to notify the server that application 1 has received the downlink data sent by the server. stream, and has no other effect. Electronic devices usually detect network quality based on the downlink network rate, and the downlink network rate is measured based on the downlink data flow sent by the server to application 1. Therefore, the uplink ACK and other confirmation messages sent by application 1 to the server will not affect the downlink rate. accuracy. Therefore, when the server sends downlink data to application 1, if application 1 sends an uplink acknowledgment message, the network quality detection result will not be affected. However, when the server stops/pauses sending downlink data to application 1, if Application 1 sends an uplink confirmation message to the server, but the electronic device cannot recognize the uplink confirmation message, and regards it as a download request message, which will make the electronic device regard the downlink network speed after receiving the uplink confirmation message as the network quality is good. Bad factors make the results of electronic equipment detection of network quality inaccurate, resulting in wrong switching of network channels. If the electronic device switches the WIFI network channel to the mobile data network channel, a large amount of mobile data traffic will be consumed due to network acceleration. For some users with a small amount of total traffic or a small amount of remaining traffic, the traffic may exceed the package limit. As a result, the user pays more than the part of the package limit, which in turn brings a bad user experience to the user.

In order to solve the problem of inaccurate detection results of the network quality of the electronic device due to the inability of the electronic device to recognize confirmation messages such as ACKs, which in turn causes incorrect switching of the network channel, an embodiment of the present application provides a network quality detection method, as follows, The specific flow of the network channel switching method will be described with reference to FIG. 6 . Please refer to FIG. 6. FIG. 6 is a flow chart of a network quality detection method provided in an embodiment of the present application. The specific process is as follows:

Step S601: Start a first application in response to a first user operation.

Specifically, the user opens the first application in the electronic device, and the first application starts. Exemplarily, as shown in FIG. 3A , when the electronic device 100 detects an input operation (eg, click) on the video application icon, the video application is started. It can be understood that the above embodiment only shows the scene of starting the first application (video application) by clicking, and does not constitute a limitation to the embodiment of the present application. In some embodiments, other operations can also be used to Ways (for example, operations such as double-clicking and sliding) to start the first application.

Wherein, the first application is a network application, that is, an application that requires networking. For example, the first application may be an online video application, an online music application, an online short video application, an online game application, a social software application, and the like.

Step S602: After the environment awareness component detects that the first application is switched to the foreground, it sends a first notification message to the policy management component.

Specifically, the environment detection component in the service layer of the electronic device can detect the state of the first application, and when the environment detection component detects that any application switches to the foreground, it sends a first notification message to the policy management component. Wherein, the first notification message is used to notify the policy management component that the first application has switched to the foreground. Wherein, the first notification message includes the identity of the first application, and the identity is used to identify the unique identity of the first application.

Step S603: After receiving the first notification message sent by the environment awareness component, the policy management component determines whether the first application satisfies the condition for enabling network acceleration.

Specifically, when the application-level policy management component receives the first notification message, it can know that the first application has switched to the foreground, and then, the application-level policy management component checks the application configuration library to determine whether the first application meets the conditions for enabling network acceleration. Wherein, the application configuration library includes configuration information of all application programs of the electronic device, and the configuration information includes but is not limited to whether each application program is granted the permission of network acceleration. The policy management component obtains the configuration information of the first application in the application configuration library based on the identity of the first application, and determines whether the first application has the authority of network acceleration. If there is the authority of network acceleration, the first application meets the requirements of network acceleration. condition, otherwise, the first application program does not meet the condition of network acceleration.

Step S604: In the case that the first application satisfies the condition for enabling network acceleration, the policy management component sends a channel activation message to the flow-level path management component, requesting activation of the main network channel.

Specifically, if the policy management component determines that the first application meets the conditions for enabling network acceleration, it can start the acceleration service for the first application, and send an acceleration enabling message to the flow-level path management component, and the acceleration enabling message is used to indicate The flow-level path management component can start the acceleration service for the first application.

The above-mentioned acceleration services may include but are not limited to: when the environment of the electronic device or the system environment of the electronic device changes, enabling a backup network channel so that the backup network channel transitions from a dormant state to a wake-up state; and/or, monitoring the first For the network quality of several streams in the application, when the electronic device monitors that the quality of a certain stream of the first application deteriorates, it switches multiple streams of the first application including the stream with degraded quality to the backup network channel, thereby The above-mentioned multiple streams of the network application are always carried on the network channel with relatively good quality, ensuring the transmission quality of the streams, reducing the possibility of service stalls in the first application, and improving user experience.

It should be noted that if the electronic device has enabled the standby network channel when the decision is made to switch multiple streams to the standby network channel, the multiple streams will be switched to the standby When the network channel is selected, if the electronic device does not enable the backup network channel, the electronic device needs to enable a backup network channel first, and then switch to the enabled backup network channel.

Optionally, the acceleration start message may include information corresponding to the identity of the first application, for example, it may include: the identity of the first application, the target flow type, the flow model corresponding to the target flow type, network quality evaluation parameter information, and Stream switching policy information. For details, reference may be made to the aforementioned related descriptions, and details are not repeated here.

Step S605: the flow-level path management component sends a second notification message to the traffic reporting component.

Specifically, the second notification message is used to notify the traffic reporting component that the first application has been switched to the foreground, and instruct the traffic reporting component to monitor the data flow between the first application and the server.

Step S606: After receiving the second notification message sent by the flow-level path management component, the traffic reporting component registers a message monitoring hook.

Specifically, after receiving the second notification message sent by the flow-level path management component, the traffic reporting component registers a message monitoring hook, which is used to monitor the data flow between the first application and the server in the network channel.

Step S607: the flow-level path management component requests the main network channel from the channel-level path management component.

Specifically, after the flow-level path management component receives the channel activation message, the flow-level path management component requests the main network channel from the channel-level path management component. In the embodiment of the present application, the electronic device supports the simultaneous use of two SIM cards (primary card and secondary card), and the mobile data service is enabled on the two SIM cards, and the electronic device is connected to two WIFI network channels (primary WIFI network) at the same time. channel and secondary WIFI network channel) as an example for illustration. Since the mobile data service of two SIM cards is enabled on the electronic device, and the electronic device is connected to two WIFI network channels at the same time, the electronic device is currently connected to four network channels, which are: main WIFI network channel, main mobile data Network channel, secondary WIFI network channel and secondary mobile data network channel. Among them, the main WIFI, the main SIM card, the secondary WIFI, and the network channels corresponding to the secondary SIM card are: the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel and the secondary mobile data network channel.

After the first application is started, the stream-level path management component can request the primary WIFI network channel, the primary mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel to be the primary network channel in sequence. If the stream-level path management component currently requests If the network channel is available (the network channel currently requested by the flow-level path management component can transmit the data flow between the first application and the server), the flow-level path management component will use this network channel as the main network channel and no longer request a network channel , otherwise, the flow-level path management component requests the main network channel from the channel-level path management component in turn according to the above order, until an available network channel is found. If no available network channel is found, the network acceleration of the first application is disabled, and the network acceleration of the first application is no longer performed. For example, the flow-level path management component requests the main WIFI network channel from the channel-level path management component. If the main WIFI network channel is available, the main WIFI network channel is used as the main network channel, and the flow-level path management component no longer requests The main mobile data network channel, the secondary WIFI network channel and the secondary mobile data network channel serve as the main network channel. If the main WIFI network channel is not available, request the main network channel in sequence according to the order of the main mobile data network channel, the secondary WIFI network channel and the secondary mobile data network channel until a network channel is found as the main network channel. If none of the above four network channels is available, the network acceleration of the first application fails, and the network acceleration of the first application is not performed, that is, the network channel of the first application is switched.

It should be understood that, the stream-level path management component may request the channel-level path management component in order of the primary network channel, the primary network channel, the secondary mobile data network channel, and The main network channel can be requested according to other orders. For example, the flow-level path management component can request the main network channel from the channel-level path management component according to the order of the main WIFI network channel, secondary WIFI network channel, primary mobile data network channel, and secondary mobile data network channel. The network channel is not limited in this embodiment of the present application.

In addition, the order in which the flow-level path management component requests the main network channel is also related to the number of network channels connected to the electronic device. For example, when the electronic device is only connected to the main WIFI network, the mobile data service of the main SIM card and the mobile data service of the secondary SIM card are enabled. Next, the electronic device is only connected to the main WIFI network channel, the main mobile data network channel, and the secondary mobile data network channel. The data network channel and the secondary mobile data network channel may also be based on other combinations of these three network channels. The embodiment of the present application does not limit the number of network channels connected to the electronic device and the order in which the flow-level path management component requests the main network channel from the channel-level path management component based on the network channels connected to the electronic device.

It should be understood that step S607 may be performed simultaneously with step S605, or may be performed before step S605, or may be performed after step S605, which is not limited in this embodiment of the present application.

Step S608: the channel-level path management component determines whether the main network channel currently requested by the flow-level path management component is available.

Specifically, after the channel-level path management component receives the main network channel request sent by the flow-level path management component, the channel-level path management component will determine whether the main network channel currently requested by the flow-level path management component is available. If it is unavailable, the channel-level path management component will return a message to the flow-level path management component, which is used to notify the flow-level path management component that the requested main network channel is unavailable, so that the flow-level path management component can apply for other network channels as the main network aisle.

It should be understood that, after the first application is started, after the flow-level path management component sends a main network channel request to the channel-level path management component, the channel-level path management component will regularly record the availability of all network channels connected to the electronic device.

Step S609: In the case that the main network channel currently requested by the flow-level path management component is an available network channel, the channel-level path management component requests the network connection component to enable the main network channel.

Exemplarily, if the flow-level path management module requests the main WIFI network channel from the channel-level path management module, and the channel-level path management module determines that the main WIFI network channel is available, the channel-level path management component will request to the network connection component The main WIFI network channel is enabled, so that the data flow between the first application and the server can be transmitted on the main WIFI network channel.

Step S610: the network connection management component enables the main network channel, and feeds back a notification message that the main network channel has been enabled to the channel-level path management component.

Step S611: the channel-level path management component requests the channel quality detection component to detect the channel quality of the main network channel.

Specifically, after the channel-level path management component receives the notification message that the main network channel has been enabled, the channel-level path management module requests the channel quality detection component to perform quality inspection on the currently enabled main network channel.

Exemplarily, the quality of the main network channel may be detected according to at least one of the following parameters of the network channel: channel delay, packet loss rate, bandwidth, and rate. For example, the above-mentioned quality detection may be to detect the round-trip time delay (Round-Trip Time, RTT) of the main network channel.

Optionally, when the currently enabled main network channel has historical selection records, that is to say, the currently enabled network channel has been used before, at this time, the quality of the main network channel can be evaluated in combination with the above RTT and historical records, wherein , the historical records may include historical receiving rates, historical times of poor channel quality, etc., and the embodiment of the present application does not specifically limit the evaluation method of the above-mentioned channel quality.

Step S612: the channel quality detection component sends the channel quality detection result to the channel-level path management component.

It should be understood that after the channel quality detection component sends the network quality detection result to the channel-level management component, the channel-level management component analyzes the network quality detection result. If the network quality of the currently enabled main network channel does not meet the requirements, The channel-level path management component executes step S609, that is: the channel-level path management module requests the network connection channel to start an available network channel based on the order of the flow-level path management module requesting the main network channel (not including the currently enabled network channel), until it finds A network channel whose network quality meets the requirements is used as the main network channel. If no main network channel whose network quality meets the requirements is found, the acceleration of the first application fails, and the acceleration of the first application is not performed.

For example, the currently enabled main network channel is the main WIFI network channel, and the available network channels include the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel, and the stream-level path management component requests available The order of the main network channel is the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel. If the network quality of the currently enabled main network channel (main WIFI network channel) does not meet the requirements, the channel-level path management component applies to the network connection component for enabling the main mobile data network channel as the main network channel, and detects the main network channel through the channel quality detection module. The network quality of the mobile data network channel, if the network quality of the main mobile data network channel meets the requirements, the channel-level path management component no longer requests the available main network channel from the network connection component, otherwise, the channel-level path management component sends the network connection component Request to use the secondary WIFI network channel and the secondary mobile data network channel as the main network channel and enable them, and then check their network quality until an available network channel with network quality that meets the requirements is found as the main network channel and enabled, realizing the first An application and an application's data stream are transmitted on the main network channel.

Step S613: The policy management component sends a traffic detection request to the traffic perception component.

Specifically, the traffic detection request may be used to instruct the traffic sensing component to start packet statistics and monitoring of network applications on the main network channel. Wherein, the traffic detection request may include the identity (such as UID) of the first application currently to be detected, and is used to request to detect the data flow between the network application corresponding to the above identity and the server on the main network channel and monitoring. It can be understood that the data stream may be in the form of a message.

It should be understood that step S613 and step S604 may be performed simultaneously, and step S613 may also be performed after step S604, which is not limited in this embodiment of the present application.

Step S614: the traffic sensing component sends a traffic reporting request to the traffic reporting component.

Specifically, after the traffic sensing component receives the traffic detection request sent by the application-level policy management component, it can send a traffic reporting request to the traffic reporting component, wherein the traffic reporting request can be used to instruct the traffic reporting The data flow transmitted between the first application and the server is detected, and the detected data flow is reported. It can be understood that the above traffic detection request may include the identity (eg, UID) of the first application.

Step S615: The traffic reporting component performs traffic detection, and reports the packet statistics information of the target flow to the traffic sensing component.

Specifically, after the traffic reporting component receives the traffic reporting request, it can detect the target flow on the main network channel according to the traffic reporting request, and report the packet statistics information of the detected target flow to the traffic sensing component. Wherein, the target flow may be a data flow transmitted between the first application and the server.

During specific implementation, the traffic reporting component can obtain the message of the target flow on the current main network channel by calling a component (for example, the Netfilter component of the Android system). It should be understood that the above-mentioned Netfilter component is only an illustration and does not constitute a limitation to the embodiment of the present application. In some embodiments, the detection of the above-mentioned target flow may also be completed through other components.

Since the traffic reporting component has registered a packet monitoring hook in advance, when the traffic reporting component performs traffic detection, the packet of the target flow can be obtained through the packet monitoring hook. The overall implementation block diagram is shown in Figure 7, for example. Netfilter hooks packets to the nf_hook hook function of the traffic reporting component, and the packets carried on the current main network channel enter the traffic reporting component. According to the process of file content analysis and other processes, the packets of the target flow are stored in the SKB queue. For the packets in the SKB queue, according to the reporting policy of the target flow to which the packet belongs, the packet statistics of the target flow that need to be reported regularly are determined by the timer Trigger reporting to the traffic sensing component.

Referring to Figure 7, the specific implementation process of the message reporting component may include:

Step S1, initialization;

When the first application is started and loaded, the traffic reporting component will receive the second notification message in the above step S606 to register the message monitoring hook function.

Step S2, message processing;

This step specifically includes three steps: packet parsing, flow table checking, and packet analysis. The flow table records the identification information of the flow in each network application and the statistical information of each flow. The statistical information of each flow may include: the number of received packets of the flow, the number of received packets of the flow The total number of bytes in the message, the number of error packets, etc. The identification information of the flow can be calculated according to the five-tuple or four-tuple of the message in the flow. The above calculation can specifically use the hash algorithm, so that the identification information of the flow can be the hash calculated by the five-tuple or four-tuple of the message. value.

When the message is parsed, the traffic reporting component obtains the message, and can analyze whether there is a UID of the first application in the message; if it exists, it indicates that the message is a message of the first application, and the quadruple ( or quintuple), perform the subsequent step of checking the flow table; if it does not exist, it means that the message is not the message of the first application, and the process ends. The above four-tuple may include: source IP, destination IP, source port, destination port; the five-tuple may include: source IP, destination IP, source port, destination port and protocol number.

When checking the flow table, you can calculate the identification information of the flow according to the four-tuple (or five-tuple) of the message, and use the calculated identification information to find out whether the identification information has been recorded in the flow table, and if so, update the flow table The statistical information corresponding to the identification information in the flow table; if not, create a flow node in the flow table according to the identification information of the flow, and update the statistical information of the flow in the flow node.

When performing packet analysis, the traffic reporting component can filter the received packets through preset conditions, so as to obtain all or part of the packets of the target flow. For example, the preset condition may be: the source IP address of the message is the IP address of the network connected to the main network channel, the destination IP address of the message is the server, source port, and destination port of the first application, or the The destination IP address is the IP address of the network connected to the main network channel, the source IP address of the message is the server of the first application, the source port, the destination port, etc. The above preset conditions can be configured to the traffic reporting component through a configuration file, and the above configuration file can be carried in the traffic reporting request sent by the traffic sensing component in step S614, and record the feature information that the message needs to match.

Step S3, report the matched target flow and statistical information of the target flow packet to the traffic perception module according to the flow reporting policy.

Step S616: The traffic sensing component detects the network quality according to the packet statistical information of the target flow reported by the packet reporting component, and judges whether to switch the network channel based on the network quality.

Specifically, the traffic reporting component periodically reports the statistical information of the target flow packets to the traffic sensing component, and periodically detects the network quality of the target flow between the first application and the server. In the following, in combination with Figure 8, the process of detecting network quality by the traffic sensing component in units of one cycle is described in detail, and the specific process is as follows:

Step S801: The traffic sensing component receives the statistical information of the current cycle target flow packets reported by the traffic reporting component.

Specifically, the traffic reporting component detects the data flow between the first application and the server, the data flow is the target data flow, and counts the uplink packets and downlink packets in the target data flow in units of periods, and the target flow reports The statistical information of the packet, and the statistical information of the target flow packet in this period is sent to the traffic awareness component. Among them, the statistical information of the target stream packet includes but not limited to: the number of uplink packets, the number of downlink packets, the protocol number of each packet, the number of bytes of the packet, the source IP address of the packet, the Destination IP address and other information.

Step S802: The traffic sensing component judges whether the first application is in a state of suspending downloading/stopping downloading according to the packet statistics information based on the current period.

Specifically, the traffic sensing component can obtain the downlink network rate of the current period and the past multiple periods from the packet statistics information of the target flow in the current period and previous periods, and judge that the first application is in the pause downloading/downloading mode based on the multiple downlink network rates. Stop downloading status. Wherein, the download state of the first application is a state in which the server sends downlink data streams to the first application. The method for the traffic perception component to judge whether the first application is in the state of suspending download/stop downloading based on the downlink network rate may be as follows: if in the current period, the downlink network rate is greater than the first rate value and less than Threshhold, and the network quality record of the previous period is For optimality, the traffic sensing component judges that the first application is in the state of suspending download/stop downloading, and does not record the network quality of the current period. Otherwise, the first application is not in the state of pausing download/stopping download. Among them, Threshhold is used to judge the network quality of the current period. If the downlink network rate of the current period is greater than or equal to Threshhold, the network quality record of the current period is excellent. If the downlink network rate of the current period is less than Threshhold, the network quality record of the current period is For difference, Threshhold is greater than the first rate value. The first rate value may be obtained from historical data or experimental data, which is not limited in this embodiment of the present application.

It should be understood that, the embodiment of the present application is only an exemplary description of the method in which the traffic sensing component determines that the first application is in the state of suspending download/stopping download based on the packet statistics information of the current period, and does not limit it.

If the first application is in the state of pausing/stopping downloading, the traffic sensing component executes step S803; if the first application is not in the state of pausing/stopping downloading, the traffic sensing component executes step S804.

Step S803: The traffic sensing component sets the download end flag as the first flag.

Specifically, the download end flag is used to indicate the download status of the first application. If the download end flag is the first flag, the traffic awareness component determines that the first application is in the state of pausing download/stop downloading. If the download end flag is not the first flag, Then the traffic sensing component determines that the first application is not in the state of pausing download/stopping download. Exemplarily, the first identifier may be characters such as "True" or "1", and this embodiment of the present application does not limit the representation method of the first identifier.

Step S804: The traffic sensing component judges whether the download end flag is the first flag.

Specifically, if the judgment is yes, the traffic sensing component executes step S806, and if the judgment is no, the traffic sensing component executes step S805.

Step S805: The traffic sensing component records the network quality of the current period based on the packet statistics information of the current period.

Specifically, the traffic sensing component can compare the downlink network rate in this period with the preset rate threshold Threshhold. If the downlink network rate is greater than or equal to Threshhold, the traffic sensing component records that the network quality in this period is excellent. If the downlink network rate is less than Threshhold , the traffic sensing component records that the network quality in this period is poor. Wherein, Threshhold may be obtained based on historical data, may also be obtained based on empirical values, and may also be obtained based on experimental data, which is not limited in this embodiment of the present application. Wherein, Threshhold is greater than the first rate value.

Step S806: The traffic sensing component does not record the network quality of this period.

Step S807: In the case that there are uplink packets, the traffic sensing component judges whether the network protocol of the uplink packets is the GQUIC protocol based on the packet statistics information of this period.

Specifically, as described in step S615, during the process of detecting the target flow, the traffic reporting component analyzes the packets in the target flow, so as to obtain the network protocol used by the packets in the target flow. After the traffic reporting component captures the message, it judges whether there is a CHLO (Client Hello) field in the upstream message, and then judges that the network protocol used by the message is the GQUIC protocol. If the GQUIC protocol is used, the traffic reporting component records it in the target flow in the packet statistics information. FIG. 9 is a schematic diagram of a datagram using the GQUIC protocol provided by the embodiment of the present application. It can be seen from FIG. 9 that the packet contains a CHLO field.

The traffic perception component judges the protocol number of the uplink packet in this period based on the packet statistics information of the target flow to judge whether the network protocol of the packet is the GQUIC protocol, if it is judged to be yes, execute step S808, if it is judged to be no, end the process.

Step S808: the traffic sensing component judges whether the uplink data message is an ACK message using the GQUIC protocol.

Specifically, when the traffic perception component determines that the network protocol used by the messages in this period is the GQUIC protocol, it judges whether the uplink data message is an ACK message, and if it is judged to be yes, it means that the uplink message is not a download request message, the network quality detection process of this cycle is completed, and the process ends, if the judgment is negative, go to step S809. The traffic perception component can judge whether the uplink message is an ACK message according to the byte length of the payload field in the uplink message. If the byte length of the payload field is greater than or equal to the first threshold (for example, 300Byte), it is not an ACK message. text, the uplink message is a download request message; otherwise, the uplink message is an ACK message. Wherein, the first threshold may be obtained from empirical values, historical data, or experimental data, which is not limited in this embodiment of the present application.

For ease of understanding, the detailed flow of the traffic perception component judging whether the uplink message is an ACK message in the above step S807-step S808 will be described below in conjunction with FIG. 10. Please refer to FIG. 10, which is provided by the embodiment of the present application A flow chart of a flow perception component judging whether an uplink message is an ACK message. The specific process is as follows:

Step S1001: The traffic sensing component judges whether there is a CHLO field in the uplink message. If it is judged as yes, execute step S1002; if it is judged as no, it means that the network protocol used by the uplink message is not GQUIC protocol, and execute step S1005.

Step S1002: the traffic sensing component determines that the network protocol of the uplink packet is the GQUIC protocol.

Step S1003: the traffic sensing component judges whether the byte length of the payload field of the uplink packet is greater than or equal to a first threshold. If it is judged as no, execute step S1004; if it is judged as yes, execute step S1005.

Step S1004: the traffic sensing component determines that the uplink message is an ACK message.

Step S1005: the traffic sensing component determines that the uplink packet is not an ACK packet.

Step S809: The traffic awareness component sets the download end flag as the second flag.

Specifically, if the uplink datagram in the current cycle is not an ACK message using the GQUIC protocol, the download end flag is set as the second flag, so that the flow sensing component judges whether to record the network quality according to the download end flag in the next cycle. As shown in Figure 11, in period 1 to period 3, the first application is in the downloading state, that is, the server sends downlink data streams to the first application, and the traffic sensing component judges that the download process is suspended in period 4, and sets the download end flag to the first One sign, the download end sign of period 5 to period 6 is the first sign, but in period 6, the flow sensing component detects that there is an uplink download request message, which means that the download of the first application has restarted, and the flow sensing component will The download end flag is set as the second flag, and in period 7, the traffic perception component determines whether to record the network quality of the current cycle based on the download end flag, and if the download end flag is not the first flag, record the network quality of the current cycle.

Next, in conjunction with Figure 12, the specific process of determining whether to switch the network channel based on the network quality recorded by the traffic sensing component in each period will be described. The specific process is as follows:

Step S1201: The traffic sensing component obtains the network quality detection results of the previous M periods adjacent to the current period.

Step S1202: Among the network quality detection results of the M periods by the flow sensing component, it is judged whether the network quality detection results of more than N periods are bad. If it is determined to be yes, execute step S1203; if it is determined to be no, execute step S1204.

In some embodiments, when the statistical period is less than M, the network quality detection result according to whether the counted period number P exceeds (N*P)/M periods is poor. If it is judged to be yes, execute step S1203, if it is judged to be no, execute step S1204

Step S1203: The flow sensing component determines to switch the network channel.

Step S1204: The traffic sensing component determines not to switch the network channel.

It should be understood that, in the above-mentioned embodiment of FIG. 12, the method in which the traffic sensing component judges whether to switch the network channel based on the network quality detection result is only an exemplary illustration. For other methods in which the traffic sensing component judges whether to switch the network channel based on the network quality detection result The method is not limited by the embodiment of this application.

Step S617: In the case of determining to switch the network channel, the traffic perception component sends a network channel switching instruction to the flow-level path management component.

Specifically, in the case of determining to switch the network channel, the traffic awareness component sends a network channel switching instruction to the flow-level path management component, and the network channel switching instruction is used to instruct the flow-level path management component to start the service of network channel switching.

Optionally, the channel switching instruction includes the identity of the first application (for example, the UID of the first application).

Step S618: the stream-level path management component requests the channel-level path management component to activate the standby network channel.

Specifically, after receiving the channel switching instruction sent by the traffic sensing component, the flow-level path management component requests the channel-level path management component to activate the standby network channel.

Step S619: the channel-level path management component requests the network connection component to activate the standby network channel.

Specifically, the channel-level path management component selects a network channel other than the main network channel as a backup network channel among currently available network channels. For example, if the electronic device is connected to the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel, and the above four network channels are all available, and the main network channel is the main WIFI network channel, then the channel level The path management component can select a network channel from the primary mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel as a backup network channel.

Step S620: The network connection management component activates the backup network channel, and feeds back a notification message that the backup network channel has been enabled to the channel-level path management component.

Specifically, enabling the standby network channel here refers to switching the standby network channel from the dormant state to the wake-up state, so that the current network channel can be quickly switched to the standby network channel when subsequent network channel switching is required. For example, the standby network channel is the primary mobile data network channel, and the method for the network connection component to activate the primary mobile data network channel is to switch the primary mobile data network channel from a dormant state to an awake state.

Step S621: the channel-level path management component requests the channel quality detection component to detect the channel quality of the standby network channel.

Step S622: the channel quality detection component sends the channel quality detection result to the channel-level path management component.

Specifically, for step S621-step S622, please refer to step S611-step S612, which will not be repeated here.

Step S623: the channel-level path management component sends the path of the standby network channel to the stream-level path management component.

Step S624: the flow-level path management component sends a network channel switching notification to the policy enforcement component.

Step S625: The policy enforcement component switches the network channel.

Specifically, after receiving the network channel switching notification sent by the flow-level path management component to the policy enforcement component, the policy enforcement component switches the network channel, and switches the data flow between the first application and the server on the main network channel to the backup network channel for processing. transmission.

In the embodiment of this application, after the electronic device detects that the application sends a download request message to the server, it will periodically detect the network quality and whether the download process is completed/paused. If the download process is completed/paused within this period, the electronic device will not The downlink network speed in this period will be used as a reference factor for judging the quality of the network. At the same time, the electronic device will identify whether the uplink datagram sent by the application to the server in this period is a download request datagram. If it is a download request datagram, the electronic device will The device sets the download end flag to the download state. Through this method, after the download process stops or pauses, the electronic device will not recognize the ACK confirmation message sent by the application to the server as a download request message, and then will receive the confirmation message. The downlink network rate after the message is used as a reference factor for judging whether to switch the network channel, thus causing the wrong switching of the network channel.
