Description

A network quality detection method and related electronic equipment

Technical Field

The present application relates to the field of network quality detection, and 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 phones and other mobile devices are increasingly used in people's daily lives. For example, mobile payments and games can be performed through mobile phones. In order to ensure the normal operation of common services (for example, games, calls, social software and other services), users' mobile phones are usually connected to wireless networks. Network acceleration is often performed when network quality deteriorates. However, when users are surfing the Internet, there are often inaccurate network quality detection problems. When network quality detection is inaccurate, network errors 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, causing the user to pay additional phone bills, thereby reducing the user's Internet experience.

Contents of the invention

Embodiments of the present application provide a network quality detection method, which solves the problem of incorrect network channel switching during network acceleration due to inaccurate network quality detection results.

In the first aspect, an embodiment of the present application provides a method, including: responding to a first operation of a user, starting a first application; periodically receiving message statistics of a target flow; the message statistics are statistical information of a data flow between the first application and a server; if it is determined based on the message statistics of the current period that the first application is in a paused download/stopped download state, the network quality of the current period is not recorded; if the uplink message is not an ACK message, the network quality of the next period is recorded. 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 a downloading state, the electronic device detects the network quality based on the downlink network rate. When the first application is in a paused download/stopped download state, the electronic device does not record the network quality. Through such a method, it is possible to solve the problem that when the first application is in the state of pausing download/ending download, the electronic device mistakenly judges the uplink message as a download request message, and continues to detect the network quality after the download is completed, causing inaccurate network quality detection results. The electronic device uses this inaccurate network detection result as a reference factor for determining whether to switch the network channel, causing the electronic device to mistakenly switch the network channel of the first application.

In a possible implementation manner, the method further includes: when the uplink message is an ACK message, determining whether the uplink message in the next cycle is an ACK message.

In a possible implementation method, judging whether the uplink message is an ACK message based on the message statistics of the current cycle includes: judging whether the network protocol of the uplink message is the GQUIC protocol based on the message statistics; in the network protocol If the network protocol is not the GQUIC protocol, it is determined that the upstream message is not an ACK message; if the network protocol is the GQUIC protocol, it is detected whether the length of the payload field of the upstream message is greater than or equal to the first threshold; if it is greater than or equal to the first threshold, A threshold is used to determine that the uplink message is not an ACK message; if it is less than the first threshold, it is determined that the uplink message is an ACK message. In this way, the electronic device can distinguish the uplink message as an ACK message or a download request message, thereby avoiding the electronic device from misjudging the uplink message as a download request message when the first application is in a download pause/end download state. Continue to detect the network quality after the download is completed, resulting in inaccurate network quality detection results, causing the electronic device to use this inaccurate network quality detection result as a reference factor to determine whether to switch network channels, thus causing the electronic device to incorrectly switch to the first application. network channel.

In this way, judging whether the network protocol of the uplink message is the GQUIC protocol through the CHLO field, when it is determined that the network protocol is the GQUIC protocol, it can be further judged whether the uplink message is an ACK message.

In one possible implementation method, the network quality is obtained based on the downlink network rate in the packet statistics 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 period is excellent. In this way, the electronic device can determine whether to switch network channels based on network quality, thereby avoiding service lags in the first application and degrading the user's Internet experience.

In a possible implementation manner, after determining whether the uplink message is an ACK message based on the current period's message statistical information, the method further includes: when the current number of statistical periods is greater than M, obtaining the corresponding period of the current period. The network quality of neighboring M cycles; determine whether the network quality for more than N cycles in the M cycles is poor; if the determination is yes, determine to switch the network channel of the first application; if the determination is no, determine Do not switch the network channel of the first application; when the current number of statistical periods is less than or equal to M, obtain the network quality of all P periods adjacent to the current period; determine whether in the P periods, it exceeds (P *N)/M cycles of network quality is poor; if the determination is yes, it is determined to switch the network channel of the first application; if the determination is no, it is determined not to switch the network channel of the first application. In this way, the electronic device can determine whether to switch network channels based on network quality, thereby avoiding service lags in the first application and degrading the user's Internet experience.

In a possible implementation manner, after judging that the uplink message is not the ACK message based on the message statistics of the current period and before recording the network quality of the next period, the method further includes: setting the download end flag. is a second identification, and the second identification is used to indicate that the first application is in a downloading start state. In this way, it is helpful for the electronic device to determine whether to record the network quality in the next cycle.

In a possible implementation manner, when it is determined that the first application is in a download pause/stop download state based on the packet statistics of the current cycle, the network quality of the current cycle is not recorded, including: packets based on the current cycle When the statistical information determines that the download end flag is the first flag, the network quality of the current period is not recorded; where 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.

Figure 3A shows the user interface 10 of the electronic device 100. The user interface 10 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 Both SIM cards have started mobile data services. As shown in Figure 3A, the electronic device 100 is currently connected to the WIFI network channel, the main mobile data network channel (the network channel corresponding to the main SIM card) and the secondary mobile data network channel (the secondary SIM card). The network channel corresponding to the card). The embodiments of this application are explained by taking the electronic device 100 using the WIFI network channel as the main network channel and the network channel currently enabled by the electronic device 100 as the main network channel as an example. The network speed display icon 304 is used to display the downlink rate of the currently enabled network channel. For example, as shown in Figure 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 Stories". When the electronic device 100 detects a single-click input operation on the video cover 311, the electronic device 100 displays the user interface 30 shown in Figure 3C.

As shown in Figure 3C, the user interface 30 is an interface for playing videos. It can be seen from Figure 3C that the network channel currently enabled by the electronic device 100 is the main network channel (assuming that the main network channel is the 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 FIG3D , during the video viewing process, the user carries the electronic device 100 and moves from the activity area 1 to the activity area 2, and then moves from the activity area 2 to the activity area 3 to turn on the air conditioner, and the distances between the activity area 1, the activity area 2, and the activity area 3 and the router 101 decrease in sequence. When the user moves to the activity area 2, the electronic device 100 displays the user interface 40 shown in FIG3E .

As shown in FIG3E , the user interface 40 is a video playback interface, the network channel currently 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. As can be seen from FIG3E , since the network quality of the electronic device 100 in the activity area 2 is worse than that in the activity area 1, the network speed of the electronic device 100 is reduced compared to that in the activity area 1. When the user moves to the activity area 3, the electronic device 100 displays the user interface 50 shown in FIG3F .

As shown in Figure 3F, the user interface 50 is a video playback interface. The video playback interface includes a network acceleration prompt box 501. The network acceleration prompt box 501 is used to prompt that network acceleration of the video application has been turned on. For example, the network acceleration prompt box 501 in Figure 3F displays the message "The switching of network channels has been completed and network acceleration is performed." It can be seen in the user interface 50 that the network channel currently enabled by the video application is the 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 has completed the switching from the main network channel to the backup network, and compared with the network rate in the active area 2, after the electronic device switches to the backup network channel in the active area 3, the network rate is greatly improved.

It should be understood that the above-mentioned Figures 3A to 3F show that when the electronic device is playing a video, the change in the straight-line distance between the electronic device and the router causes changes in the network quality. The electronic device performs operations based on the detected network quality. A set of exemplary user interfaces for network channel switching should not limit the embodiments of the present application.

Figures 2 to 3F above introduce the application scenarios of electronic equipment for network quality detection. In the above embodiment, when the user moves from activity area 1 to activity area 2, and then from activity area 2 to activity area 3, since the linear distance between the electronic device and the router continues to increase, the network quality deteriorates, and further As a result, the network speed of electronic devices continues to decrease. When the network rate of an electronic device drops to a certain threshold, the electronic device will switch the network channel (for example, from the WIFI network channel to the main mobile data network channel), and the network quality after the switch will be compared with the network quality before the switch. better.

Next, the principle of the network quality detection method for electronic equipment is introduced with reference to the accompanying drawings. As shown in Figure 4, the electronic equipment transmits data streams with the server through the WIFI network channel. The WIFI network channel includes multiple stream channels (in the figure Only two flow channels are listed), among which flow channel A is used to transmit the upstream data flow from application 1 to the server, and flow channel B is used by the server to transmit the downlink data flow to application 1. After application 1 sends an uplink message to the server through flow channel 1, the electronic device begins to detect the network quality of the downlink data stream (for example, the transmission rate of the downlink datagram, the delay of the datagram, the packet loss rate, etc.). After detecting When the network quality of the data flow deteriorates, the data flow between 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. After the server receives the uplink download request message, it sends a downlink data stream to Application 1. At this time, the electronic device will be triggered to perform message detection on the downlink data stream, thereby detecting the network quality of the current data stream and determining whether the network channel needs to be switched based on the network quality. After the server finishes sending the downlink data stream, the electronic device will no longer perform related operations such as network quality detection and network channel switching.

However, as shown in Figure 5, when application 1 uses a protocol such as GQUIC to transmit uplink messages, after application 1 sends an uplink download request message to the server, the server sends a downlink data stream to application 1. During the process of the server sending the downlink data stream to Application 1, Application 1 may send uplink ACK and other confirmation messages to the server. Such confirmation messages are only used to notify the server that Application 1 has received the downlink data sent by the server. Flow, 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 stream sent by the server to Application 1. Therefore, Application 1 sends uplink ACK and other confirmation messages to the server without affecting the downlink rate. accuracy. Therefore, while the server is sending downlink data flow to application 1, if application 1 sends an uplink confirmation message, it will not affect the network quality detection results. However, when the server stops/pauses sending downlink data flow to application 1, if Application 1 sends an uplink confirmation message to the server, and the electronic device cannot recognize the uplink confirmation message and treats it as a download request message. This will cause the electronic device to regard the downlink network rate after receiving the uplink confirmation message as the network quality is good. Bad factors make the results of electronic equipment detecting network quality inaccurate, resulting in incorrect network channel switching. If an 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 total traffic package or a small amount of remaining traffic, the traffic may exceed the package limit. As a result, the user pays more than the package limit, which in turn brings a bad user experience to the user.

In order to solve the problem that the electronic device cannot recognize ACK and other confirmation messages, resulting in inaccurate detection results of the electronic device network quality, and thus causing the network channel to be mis-cut, the embodiment of the present application provides a network quality detection method. The specific process of the network channel switching method is described below in conjunction with Figure 6. Please refer to Figure 6, which is a flow chart of a network quality detection method provided by the embodiment of the present application. The specific process is as follows:

Step S601: In response to the user's first operation, start the first application.

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

Among them, the first application is a network application, that is, an application that requires networking. For example, the first application can be an online video application, an online music application, an online short video application, an online game application, a social software application, etc.

Step S602: After detecting that the first application switches to the foreground, the environment awareness component sends a first notification message to the policy management component.

Specifically, the environment detection component in the electronic device service layer can detect the state of the first application, and when the environment perception component detects that any application has switched to the foreground, it sends a first notification message to the policy management component. The first notification message is used to notify the policy management component that the first application has switched to the foreground. The first notification message includes an identity identifier of the first application, which 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 meets the conditions for turning on network acceleration.

Specifically, when the application-level policy management component receives the first notification message, it can be learned that the first application has switched to the foreground, and then the application-level policy management component determines whether the first application meets the conditions for enabling network acceleration by querying the application configuration library. The application configuration library includes configuration information of all applications of the electronic device, and the configuration information includes but is not limited to whether each application is granted permission for 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 permission for network acceleration. If it has permission for network acceleration, the first application meets the conditions for network acceleration, otherwise, the first application does not meet the conditions for network acceleration.

Step S604: When the first application meets the conditions 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 turning on network acceleration, it can start the acceleration service for the first application, and send an acceleration enablement message to the flow-level path management component, where the acceleration enablement 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: activating a backup network channel when the environment of the electronic device or the system environment of the electronic device changes, causing the backup network channel to transition from a sleep state to a wake-up state; and/or monitoring the first The network quality of several streams in the application. When the electronic device monitors that the quality of a stream of the first application has deteriorated, it switches multiple streams of the first application, including the above-mentioned streams with deteriorated quality, to the backup network channel, thereby This allows the above-mentioned multiple streams of network applications to always be carried on relatively good-quality network channels, ensuring the transmission quality of the streams, reducing the possibility of service lags in the first application, and improving user experience.

It should be noted that if the decision is made to switch multiple flows to the backup network channel, the electronic device has already enabled the backup network channel, then the multiple flows will be switched to the backup network channel that has been enabled. When using a network channel, if the electronic device does not enable a backup network channel, the electronic device needs to first enable a backup network channel 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, the identity of the first application, the target flow type, the flow model corresponding to the target flow type, network quality assessment parameter information, and flow switching strategy information. For details, please refer to the above related instructions, which will not be 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 the packet monitoring hook.

Specifically, after the traffic reporting component receives the second notification message sent by the flow-level path management component, it 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 stream-level path management component requests the channel-level path management component for the main network channel.

Specifically, after the flow-level path management component receives the channel enable 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 two SIM cards enable mobile data services, and the electronic device is connected to two WIFI network channels (main WIFI network) at the same time. channel and secondary WIFI network channel) as an example. Since the electronic device has turned on the mobile data services of two SIM cards, 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, namely: main WIFI network channel, main mobile data Network channel, secondary WIFI network channel and secondary mobile data network channel. Among them, the network channels corresponding to the main WIFI, main SIM card, secondary WIFI, and secondary SIM card are: primary WIFI network channel, primary mobile data network channel, secondary WIFI network channel, and secondary mobile data network channel.

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

It should be understood that the flow-level path management component can sequentially request the channel-level path management component in addition to the main network channel according to the order of the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel. The main network channel can be requested according to other sequences. For example, the flow-level path management component can request the main network channel from the channel-level path management component in sequence according to the order of the main WIFI network channel, the secondary WIFI network channel, the primary mobile data network channel, and the secondary mobile data network channel. Network channel, the embodiment of this application does not limit this.

In addition, the order in which the flow-level path management component requests the main network channels 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 of the secondary SIM card are enabled. Under this circumstance, 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 order in which the flow-level path management component requests the main network channel from the channel-level path management component can be the main WIFI network channel, the main mobile data network channel, and the main WIFI network channel. The data network channel and the secondary mobile data network channel can also be in sequence based on other combinations of these three network channels. The embodiments of the present application do 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 executed at the same time as step S605, may be executed before step S605, or may be executed after step S605. The embodiment of the present application does not limit this.

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, when 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 determines 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. This message 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 stream-level path management component sends a primary network channel request to the channel-level path management component, the channel-level path management component will periodically record the availability of all network channels to which the electronic device is connected.

Step S609: When 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.

For example, 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 the network connection component. Enable the main WIFI network channel 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 detection on the currently enabled main network channel.

Exemplarily, the quality of the primary network channel may be detected based on at least one of the following parameters of the network channel: channel delay, packet loss rate, bandwidth and rate, etc. For example, the above quality detection may be to detect the round-trip time (RTT) of the primary network channel.

Optionally, when the currently enabled main network channel has a historical selection record, that is, the currently enabled network channel has been enabled before, at this time, the quality of the main network channel can be evaluated based on the above RTT and historical records, where , the historical record may include the historical reception rate, the historical number of times when the channel quality was poor, etc. The embodiment of the present application does not place special limitations on 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 in which the flow-level path management module requests the main network channel (excluding 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 a main network channel whose network quality meets the requirements is not found, the acceleration of the first application will be invalid and the first application will not be accelerated.

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 order in which the stream-level path management component requests the available main network channels 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 to enable the main mobile data network channel as the main network channel, and detects the network quality of the main mobile data network channel through the channel quality detection module. If the network quality of the main mobile data network channel meets the requirements, the channel-level path management component no longer requests the network connection component for the available main network channel. Otherwise, the channel-level path management component sequentially requests the network connection component to use the secondary WIFI network channel and the secondary mobile data network channel as the main network channel, and enables them, and then detects their network quality, until an available network channel with network quality that meets the requirements is found as the main network channel, and enabled, so as to achieve the transmission of the data stream of the first application and the application program on the main network channel.

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

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

It should be understood that step S613 and step S604 can be executed at the same time, and step S613 can also be executed 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, when the traffic perception 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 component to detect the data flow transmitted between the first application and the server on the current main network channel, and report the detected data flow. It can be understood that the above-mentioned traffic detection request can include the identity of the first application (such as UID).

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 of the detected target flow to the traffic sensing component. The target stream may be a data stream transmitted between the first application and the server.

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

Since the traffic reporting component has registered the packet monitoring hook in advance, when the traffic reporting component performs traffic detection, it can obtain the packets of the target flow through the packet monitoring hook. The overall implementation block diagram is shown in Figure 7, for example. Netfilter hooks the nf_hook hook function of the traffic reporting component. The packets currently carried on the main network channel enter the traffic reporting component. The traffic reporting component undergoes message parsing, flow table creation, and reporting. Through processes such as packet content analysis, 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 packets belong, 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 starts to be loaded, the traffic reporting component will receive the second notification message in step S606 and register the packet monitoring hook function.

Step S2, message processing;

This step specifically includes three steps: message parsing, flow table query, and message analysis. The flow table records the identification information of the flows in each network application and the statistical information of each flow. The statistical information of each flow may include: the number of messages received for the flow, the total number of bytes of the messages received for the flow, the number of erroneous packets, etc. The identification information of the flow can be calculated based on the five-tuple or four-tuple of the messages in the flow. The above calculation can specifically use a hash algorithm, so that the identification information of the flow can be a hash value calculated from the five-tuple or four-tuple of the message.

During message parsing, the traffic reporting component obtains the message and can parse whether the UID of the first application exists in the message; if so, it means that the message is the message of the first application, parse the four-tuple (or five-tuple) of the message, and perform the subsequent flow table query steps; if not, 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 based on the four-tuple (or five-tuple) of the message, and use the calculated identification information to find whether the identification information has been recorded in the flow table. 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 based on 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 received packets based on preset conditions to obtain all or part of the packets in 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 of the first application, the source port, the destination port, etc., or the message's The destination IP address is the IP address of the network connected to the main network channel, and the source IP address of the message is the server of the first application, source port, destination port, etc. The above preset conditions can be configured to the traffic reporting component through a configuration file. The above configuration file can be carried in the traffic reporting request sent by the traffic sensing component in step S614, and records the characteristic information that the packet needs to match.

Step S3: Report the matched target flow and the statistical information of the target flow packet to the traffic sensing module according to the flow reporting policy.

Step S616: The traffic sensing component detects the network quality based on the packet statistical information of the target flow reported by the packet reporting component, and determines 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. Next, combined with Figure 8, the process of detecting network quality by the traffic sensing component in one cycle is explained in detail. The specific process is as follows:

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

Specifically, the traffic reporting component detects the data flow between the first application and the server, which is the target data flow, and counts the uplink messages and downlink messages in the target data flow in units of periods, the statistical information of the target flow messages, and sends the statistical information of the target flow messages of this period to the traffic perception component. Among them, the statistical information of the target flow messages includes but is not limited to: the number of uplink messages, the number of downlink messages, the protocol number of each message, the number of bytes of the message, the source IP address of the message, the destination IP address of the message, and other information.

Step S802: The traffic sensing component determines whether the first application is in a state of pausing downloading/stopping downloading based on the message statistics information of this cycle.

Specifically, the traffic sensing component can obtain the downlink network rate of the current cycle and the past multiple cycles from the message statistics of the target flow of the current cycle and the previous cycles, and judge the first application to be in the suspended download/stop download state based on the multiple downlink network rates. Among them, the download state of the first application is the state of the server sending the downlink data flow to the first application. The method for the traffic sensing component to judge whether the first application is in the suspended download/stop download state based on the downlink network rate can be: if in the current cycle, the downlink network rate is greater than the first rate value, less than Threshhold, and the network quality record of the previous cycle is excellent, the traffic sensing component judges that the first application is in the suspended download/stop download state, and does not record the network quality of the current cycle. Otherwise, the first application is not in the suspended download/stop download state. Among them, Threshhold is used to judge the network quality of the current cycle. If the downlink network rate of the current cycle is greater than or equal to Threshhold, the network quality record of the current cycle is excellent. If the downlink network rate of the current cycle is less than Threshhold, the network quality record of the current cycle is poor, and Threshhold is greater than the first rate value. The first rate value can be obtained from historical data or experimental data, and the embodiment of the present application is not limited.

It should be understood that the embodiment of the present application is only an illustrative description of the method by which the traffic sensing component determines that the first application is in a download pause/stop download state based on the packet statistics of the current cycle, and is not limiting.

If the first application is in a paused download/stopped download state, the traffic sensing component executes step S803; if the first application is not in a paused download/stopped download state, 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 identification, the traffic sensing component determines that the first application is in the download pause/stop download state. If the download end flag is not the first identification, Then the traffic sensing component determines that the first application is not in a download pause/stop download state. For example, the first identifier may be a character such as "True" or "1", and the embodiment of this application does not limit the method of expressing the first identifier.

Step S804: The traffic sensing component determines whether the download end mark is the first mark.

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 this period based on the message statistics of this period.

Specifically, the traffic sensing component can compare the downlink network rate of 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 of this period is excellent. If the downlink network rate is less than Threshhold, the traffic sensing component records that the network quality of this period is poor. Among them, Threshhold can be obtained based on historical data, based on empirical values, or based on experimental data, and the embodiments of the present application do not limit this. Among them, Threshhold is greater than the first rate value.

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

Step S807: When there is an upstream packet, the traffic sensing component determines whether the network protocol of the upstream packet is the GQUIC protocol based on the packet statistics of this cycle.

Specifically, as described in step S615, during the process of detecting the target flow, the traffic reporting component parses the packets in the target flow, thereby obtaining the network protocol used by the packets in the target flow. After capturing the message, the traffic reporting component determines whether there is a CHLO (Client Hello) field in the upstream message, and then determines 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. Figure 9 is a schematic diagram of a datagram using the GQUIC protocol provided by an embodiment of the present application. It can be seen from Figure 9 that the packet contains a CHLO field.

The traffic perception component determines the protocol number of the uplink message in this cycle based on the message statistics of the target flow to determine whether the network protocol of the message 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 determines whether the uplink data packet is an ACK packet using the GQUIC protocol.

Specifically, when the traffic sensing component determines that the network protocol used by the packets in this cycle is the GQUIC protocol, it determines whether the upstream data packet is an ACK packet. If it is determined to be yes, it means that the upstream packet is not a download request. message, the network quality detection process of this cycle is completed, and the process ends. If the judgment is no, step S809 is executed. The traffic sensing component can determine whether the upstream message is an ACK message based on the byte length of the payload field in the upstream message. If the byte length of the payload field is greater than or equal to the first threshold (for example, 300 Byte), it will not be reported as an ACK message. message, the uplink message is a download request message, otherwise, the uplink message is an ACK message. The first threshold can be obtained from empirical values, historical data, or experimental data, which are not limited by the embodiments of this application.

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

Step S1001: The traffic sensing component determines whether the uplink message has a CHLO field. If the determination is yes, step S1002 is executed. If the determination is no, it indicates that the network protocol used by the uplink message is not the GQUIC protocol, and step S1005 is executed.

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

Step S1003: The traffic sensing component determines whether the byte length of the payload field of the uplink message is greater than or equal to the first threshold. If the determination is no, step S1004 is executed; if the determination is yes, step S1005 is executed.

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 message is not an ACK message.

Step S809: The traffic sensing 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 traffic sensing component determines whether to record the network quality based on the download end flag in the next cycle. As shown in Figure 11, in cycle 1 to cycle 3, the first application is in the downloading state, that is, the server sends a downstream data stream to the first application. The traffic sensing component determines that the download process is suspended in cycle 4, and sets the download end flag to the first application. First identification, the download end flags in cycles 5 to 6 are all the first identification, but in cycle 6, the traffic sensing component detects an uplink download request message. At this time, it means that the download of the first application has restarted, and the traffic sensing component will The download end flag is set to the second flag. In period 7, the traffic sensing component determines whether to record the network quality of the current period based on the download end flag. If the download end flag is not the first flag, the network quality of the current period is recorded.

Next, combined with Figure 12, the specific process for the traffic sensing component to determine whether to switch the network channel based on the network quality recorded in each cycle will be described. The specific process is as follows:

Step S1201: The traffic sensing component obtains the network quality detection results of the first M cycles adjacent to the current cycle.

Step S1202: Among the network quality detection results of the M periods, the traffic sensing component determines whether the network quality detection results of more than N periods are poor. If it is determined to be yes, step S1203 is executed; if it is determined to be no, step S1204 is executed.

In some embodiments, when there are less than M statistical periods, the network quality detection result is poor based on whether the number of statistical periods P exceeds (N*P)/M periods. If it is determined to be yes, step S1203 is executed; if it is determined to be no, step S1204 is executed.

Step S1203: The traffic 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 Figure 12 embodiment, the method in which the traffic perception component determines whether to switch the network channel based on the network quality detection results is only an exemplary description, and the embodiments of the present application do not limit other methods in which the traffic perception component determines whether to switch the network channel based on the network quality detection results.

Step S617: When it is determined to switch the network channel, the traffic sensing 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 perception component sends a network channel switching instruction to the flow-level path management component, where the network channel switching instruction is used to instruct the flow-level path management component to start the network channel switching service.

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

Step S618: The flow-level path management component requests the channel-level path management component to enable the backup 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 enable the backup network channel.

Step S619: The channel-level path management component requests the network connection component to enable the backup network channel.

Specifically, the channel-level path management component selects a network channel other than the main network channel as the backup network channel among the 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 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 main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel as the 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 backup network channel here refers to switching the backup network channel from the sleep state to the wake-up state, so that when subsequent network channel switching is required, the current network channel can be quickly switched to the backup network channel. For example, if the backup network channel is the main mobile data network channel, the method for the network connection component to start the main mobile data network channel is to convert the main mobile data network channel from the sleep state to the wake-up state.

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

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

Specifically, please refer to step S611 to step S612 for steps S621 to S622, which will not be described again here.

Step S623: The channel-level path management component sends the path of the backup network channel to the flow-level path management component.

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

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

Specifically, after receiving the network channel switching notification sent by the flow-level path management component to the policy execution component, the policy execution 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. transmission.

In the embodiment of this application, after detecting that the application sends a download request message to the server, the electronic device will periodically detect the network quality and whether the download process is ended/paused. If the download process is ended/paused within this cycle, the electronic device will not The downlink network rate in this cycle will be used as a reference factor to judge 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 cycle is a download request datagram. If it is a download request datagram, the electronic device will The device sets the download end flag bit to the download status. In this way, it is avoided that after the download process is stopped or paused, the electronic device will recognize the ACK confirmation message sent by the application to the server as a download request message, and then receive the confirmation message. The downlink network rate after the packet is used as a reference factor to determine whether to switch the network channel, resulting in incorrect switching of the network channel.
