Description

Network quality detection method and related electronic equipment

Technical Field

The present disclosure relates to the field of network quality detection, and in particular, to a method for detecting network quality and related electronic devices.

Background

With the rapid development of electronic technology and internet technology, mobile devices such as mobile phones are increasingly used in daily life, for example, mobile payment and games can be performed through the mobile phones. To ensure proper operation of common services (e.g., gaming, talking, social software, etc.), a user's handset is typically connected to a wireless network. In case of a degradation of the network quality, network acceleration is typically performed. However, in the internet surfing process of the user, the problem of inaccurate network quality detection often exists, the problem of network miscut can occur under the condition of inaccurate network quality detection, the user can use a large amount of data traffic to accelerate the network, and under the condition of insufficient package of the user data traffic, the package limit of the user can be exceeded, so that the user needs to pay additional telephone fees, and the internet surfing experience of the user is reduced.

Disclosure of Invention

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

In a first aspect, embodiments of the present application provide a method, including: responding to a first operation of a user, and starting a first application; periodically receiving message statistical information of a target stream; the message statistical information is statistical information of data flow between the first application and the server; under the condition that the first application is judged to be in a downloading suspension/downloading suspension state based on the message statistical information of the current period, the network quality of the current period is not recorded; judging whether the uplink message is an ACK message or not based on the message statistical information of the current period; and recording the network quality of the next period under the condition that the uplink message is not the ACK message. In the above embodiment, it is determined whether the uplink packet is an ACK packet, if the uplink packet is an ACK packet, 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 detects the network quality based on the downlink network rate, and when the first application is in the condition of suspending the download/ending the download, the electronic device does not record the network quality. By the method, the problem that the electronic equipment erroneously judges the uplink message as the downloading request message when the first application is in a state of suspending downloading/ending downloading, network quality after the downloading is continuously detected, so that an inaccurate network quality detection result is caused, and the electronic equipment uses the inaccurate network detection result as a reference factor for judging whether to switch network channels or not, so that the electronic equipment erroneously switches the network channels of the first application is solved.

In one possible implementation, the method further includes: and judging whether the uplink message in the next period is an ACK message or not under the condition that the uplink message is the ACK message.

In one possible implementation manner, determining whether the uplink message is an ACK message based on the message statistics information of the current period specifically includes: judging whether the network protocol of the uplink message is a GQUIC protocol or not based on the message statistical information; under the condition that the network protocol is not GQUIC protocol, determining that the uplink message is not an ACK message; under the condition that the network protocol is a GQUIC protocol, detecting whether the length of a payload field of an uplink message is larger than or equal to a first threshold value; if the uplink message is greater than or equal to a first threshold value, determining that the uplink message is not an ACK message; and if the uplink message is smaller than the first threshold value, determining that the uplink message is an ACK message. In this way, the electronic device can distinguish the uplink message as the ACK message or the download request message, so that the electronic device can avoid that the electronic device erroneously judges the uplink message as the download request message in a state that the first application is in a state of suspending the download/ending the download, continuously detects the network quality after the download is ended, causes inaccuracy of a network quality detection result, and uses the inaccurate network quality detection result as a reference factor for judging whether to switch the network channel, thereby enabling the electronic device to erroneously switch the network channel of the first application.

In one possible implementation manner, determining whether the network protocol of the uplink packet is a gqic protocol based on packet statistics information includes: judging whether the CHLO field exists in the uplink message; if the CHLO field exists, determining that the network protocol of the uplink message is GQUIC protocol; if the CHLO field does not exist, the network protocol of the uplink message is determined not to be GQUIC protocol. In this way, whether the network protocol of the uplink message is the gqic protocol is judged through the chol field, and whether the uplink message is an ACK message can be further judged under the condition that the network protocol is determined to be the gqic protocol.

In one possible implementation, the network quality is obtained based on the downlink network rate in the current period of the packet statistics; if the downlink network rate is less than or equal to a preset rate threshold, the network quality record of the current period is poor; if the downlink network rate is greater than a preset rate threshold, the network quality record of the current period is good. Therefore, the electronic equipment can judge whether to switch the network channel based on the network quality, so that the service jamming of the first application is avoided, and the Internet surfing experience of a user is reduced.

In one possible implementation manner, after the determining whether the uplink packet is an ACK packet based on the packet statistics information of the current period, the method further includes: under the condition that the current statistical period number is larger than M, acquiring network quality of M periods adjacent to the current period; judging whether the network quality exceeding N periods is poor in the M periods; if yes, determining to switch the network channel of the first application; if not, determining not to switch the network channel of the first application; under the condition that the current statistical period number is less than or equal to M, acquiring network quality of all P periods adjacent to the current period; judging whether the network quality exceeding (P x N)/M periods is poor in the P periods; if yes, determining to switch the network channel of the first application; if not, determining not to switch the network channel of the first application. Therefore, the electronic equipment can judge whether to switch the network channel based on the network quality, so that the service jamming of the first application is avoided, and the Internet surfing experience of a user is reduced.

In one possible implementation manner, after determining that the uplink packet is not the ACK packet based on the packet statistics information of the current period, before recording the network quality of the next period, the method further includes: and setting a downloading end mark as a second mark, wherein the second mark is used for representing that the first application is in a downloading starting state. In this way, the electronic device is facilitated to determine whether to record network quality in the next cycle.

In one possible implementation manner, in a case that the first application is determined to be in a state of suspending downloading/stopping downloading based on the packet statistics information of the current period, not recording the network quality of the current period, including: under the condition that the downloading end mark is judged to be the first mark based on the message statistical information of the current period, the network quality of the current period is not recorded; the downloading end mark is used for representing the downloading state of the first application; the first identification is used to characterize that the first application is in a suspended download/stopped download state.

In one possible implementation manner, when the download ending flag is determined to be the first flag based on the packet statistics information of the current period, before the network quality of the current period is not recorded, the method further includes: judging whether the downloading end mark is set as the first mark according to the message statistical information of the current period; if yes, setting a downloading end mark as the first mark; and judging whether the downloading end mark is a first mark or not.

Next, an application scenario of the network quality detection method provided in the embodiment of the present application is described in connection with fig. 2 to fig. 3F.

Fig. 2 is a view of an indoor network connection scenario provided in an embodiment of the present application, where the indoor scenario is a living room of a user. The router 101 is included in the living room of the user, the router 101 is connected with a network to send out a WIFI signal, so that the electronic equipment 100, the television 103 and the intelligent air conditioner 104 in the living room can be connected with the network through the WIFI signal emitted by the router 101, and the electronic equipment 100, the television 103 and the intelligent air conditioner 104 are located in the same local area network. Fig. 2 illustrates an example in which a user currently uses the electronic device 100 to connect to a network through WIFI and watch a video online, and it is assumed that coverage of a WIFI signal transmitted by the router 101 is only a living room, and network quality of the electronic device 100 after connecting to WIFI is degraded as a distance between the electronic device 100 and the router 101 increases.

In the following, in the process of online watching video by a user, referring to fig. 3A to 3F, an application scenario in which an electronic device performs network channel switching is described due to degradation of network quality, and fig. 3A to 3F are exemplary interfaces provided by the embodiments of the present application, in which a group of users use the electronic device 100 to online watch video.

Fig. 3A is a user interface 10 of the electronic device 100, including a WIFI network icon 301, a mobile data icon 302, a video application icon 303, a web speed display icon 304, and other application icons in the user interface 10. The WIFI network icon 301 is used to indicate that the electronic device 100 is connected to the WIFI network channel, the mobile data icon 302 is used to indicate that the electronic device 100 is connected to the mobile data network channel, and it is assumed that the electronic device 100 has a main SIM card and a sub SIM card, and both SIM cards start mobile data services, as can be seen from fig. 3A, the electronic device 100 is currently connected to the WIFI network channel, the main mobile data network channel (network channel corresponding to the main SIM card), and the sub mobile data network channel (network channel corresponding to the sub SIM card). In the embodiment of the present application, the electronic device 100 takes the WIFI network channel as the main network channel, and the network channel enabled by the current electronic device 100 is taken 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 fig. 3A, the downlink rate of the current WIFI network channel is 1.4M/S. When the electronic device 100 detects a click input operation for the video application icon 303, the electronic device 100 displays the user interface 20 as described in fig. 3B in response to the input operation.

As shown in fig. 3B, the user interface 20 is a main interface of the video application, and includes a video recommendation area 310, where a video cover 311 currently displayed in the video recommendation area is a "story of a pet", and when the electronic device 100 detects a click input operation with respect to the video cover 311, the electronic device 100 displays the user interface 30 as shown in fig. 3C.

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

As shown in fig. 3D, during video viewing, the user moves the electronic device 100 from the active area 1 to the active area 2, then from the active area 2 to the active area 3, and the air conditioner is turned on, and the distances between the active area 1, the active area 2, the active area 3 and the router 101 decrease sequentially. When the user moves to the active area 2, the electronic device 100 displays the user interface 40 as shown in FIG. 3E.

As shown in fig. 3E, the user interface 40 is a video playing interface, the network channel enabled by the current electronic device 100 is a main network channel, the current network speed is 512k/s, and the playing progress of the current video is 06:48. As can be seen from fig. 3E, since the network quality of the electronic device 100 at the active area 2 is lower than that at the active area 1, the network speed of the electronic device 100 is reduced compared with that at the active area 1, and when the user moves to the active area 3, 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 playing interface, and the video playing interface includes a network acceleration prompt box 501, where the network acceleration prompt box 501 is used to prompt the network acceleration of the started video application. 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". As can be seen in the user interface 50, the network channel enabled by the current video application is a standby network channel, the current network speed is 1.8M/s, and the playing progress of the current video is 06:48. The electronic device 100 completes the switch from the primary network channel to the standby network and the network rate is greatly increased after the electronic device switches to the standby network channel in the active area 3 compared to the network rate in the active area 2.

It should be understood that fig. 3A-3F illustrate a set of exemplary user interfaces for performing network channel switching by the electronic device based on the detected network quality due to a change in the linear distance between the electronic device and the router during video playing of the electronic device, which should not limit embodiments of the present application.

Fig. 2 to fig. 3F describe application scenarios of the electronic device for network quality detection. In the above embodiment, in the process that the user moves from the active area 1 to the active area 2 and then from the active area 2 to the active area 3, the network quality is degraded due to the continuous increase of the linear distance between the electronic device and the router, so that the network rate of the electronic device is continuously reduced. When the network rate of the electronic device decreases to a certain threshold, the electronic device switches the network channel (e.g., from the WIFI network channel to the main mobile data network channel), and the network quality after switching is better than the network quality before switching.

In the following, referring to the drawings, the principle of the network quality detection method of the electronic device is described, as shown in fig. 4, the electronic device performs data stream transmission with the server through a WIFI network channel, where the WIFI network channel includes a plurality of flow channels (only two flow channels are listed in the drawing), where the flow channel a is used for transmitting an uplink data stream from the application 1 to the server, and the flow channel B is used for transmitting a downlink data stream from the server to the application 1. After the application 1 sends an uplink packet to the server through the flow channel 1, the electronic device starts to detect the quality of the downlink data flow network (for example, the transmission rate of the downlink data packet, the delay time of the data packet, the packet loss rate, etc.), and when detecting that the network quality of the data flow is poor, switches the data flow between the application 1 and the server to the mobile data network channel for transmission.

The application 1 and the server generally use a UDP protocol to transmit a message, and the application 1 sends an uplink download request message to the server first, so as to be used for communicating with the server, and after the server receives the uplink download request message, the server sends a downlink data stream to the application 1, and at this time, the electronic device is triggered to detect the downlink data stream, thereby detecting the network quality of the current data stream, and judging whether the switching of the network channel is required according to the network quality. After the server sends the downlink data stream, the electronic equipment does not perform related operations such as network quality detection, network channel switching and the like.

However, as shown in fig. 5, when the application 1 transmits an uplink packet using a protocol such as gqic, the application 1 transmits an uplink download request packet to the server, and then the server transmits a downlink data stream to the application 1. In the process that the server sends the downlink data stream to the application 1, the application 1 may send an acknowledgement message such as an uplink ACK to the server, where the acknowledgement message is only used to inform the server, and the application 1 has received the downlink data stream sent by the server, and has no other effect. The electronic device typically detects the network quality based on the downlink network rate, which is measured based on the downlink data stream sent by the server to the application 1, so that the accuracy of the downlink rate is not affected by the application 1 sending an acknowledgement message such as an uplink ACK to the server. Therefore, in the process that the server sends the downlink data stream to the application 1, if the application 1 sends the uplink acknowledgement message, the network quality detection result is not affected, but after the server stops/pauses sending the downlink data stream to the application 1, if the application 1 sends the uplink acknowledgement message to the server, the electronic device cannot identify the uplink acknowledgement message and uses the uplink acknowledgement message as the download request message, the electronic device uses the downlink network rate after receiving the uplink acknowledgement message as a factor of good network quality, so that the network quality detection result of the electronic device is inaccurate, and the network channel is switched erroneously. If the electronic device switches the WIFI network channel to the mobile data network channel, a large amount of mobile data traffic is consumed due to network acceleration, and for some users with small total or small residual traffic, the traffic may exceed the package limit, so that the user pays more telephone fees exceeding the package limit, and bad use experience is brought to the user.

In order to solve the problem that the network quality of the electronic device is inaccurate in detection result and thus the network channel is miscut because the electronic device cannot identify the acknowledgement message such as the ACK, the embodiment of the application provides a network quality detection method, and a specific flow of the network channel switching method is described below with reference to fig. 6. Referring to fig. 6, fig. 6 is a flowchart of a network quality detection method provided in an embodiment of the present application, and the specific flow is as follows:

step S601: the first application is launched in response to a first operation by the user.

Specifically, a user opens a first application in an electronic device, and the first application is started. Illustratively, as shown in fig. 3A, when the electronic device 100 detects an input operation (e.g., a click) for a video application icon, a video application is launched. It will be appreciated that the above embodiments are merely illustrative of a scenario in which the first application (video application) is launched by clicking, and do not constitute a limitation of the embodiments of the present application, and in some embodiments, the first application may be launched by other operation manners (e.g., double clicking, sliding, etc.).

The first application is a network application, i.e. an application needing to be networked, 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 context awareness component detects that the first application is switched to the foreground, a first notification message is sent to the policy management component.

Specifically, the environment detection component in the service layer of the electronic device may detect a state of the first application, and when the environment sensing component detects that any application is switched to the foreground, send 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 been switched to the foreground. Wherein the first notification message includes an identity of the first application, the identity being used to identify a unique identity of the first application.

Step S603: and after receiving the first notification message sent by the environment sensing component, the policy management component judges whether the first application meets the condition of starting network acceleration.

Specifically, after the application level policy management component receives the first notification message, it can learn that the first application is switched to the foreground, and then the application level policy management component determines whether the first application meets a condition of starting network acceleration by querying an application configuration library. Wherein the application configuration library includes configuration information for all applications of the electronic device including, but not limited to, whether each application is granted network acceleration rights. The policy management component obtains configuration information of the first application from an application configuration library based on the identity of the first application, determines whether the first application has network acceleration permission, if so, the first application program meets the network acceleration condition, otherwise, the first application program does not meet the network acceleration condition.

Step S604: and under the condition that the first application meets the condition of starting network acceleration, the policy management component sends a channel enabling message to the flow-level path management component to request to enable the main network channel.

Specifically, if the policy management component determines that the first application satisfies the condition of starting network acceleration, an acceleration service for the first application may be started, and an acceleration enabling message is sent to the flow-level path management component, where the acceleration enabling message is used to instruct the flow-level path management component to start the acceleration service for the first application.

The acceleration traffic may include, but is not limited to: when the environment of the electronic equipment or the system environment of the electronic equipment is changed, a standby network channel is started, so that the standby network channel is converted from a dormant state to an awakening state; and/or monitoring the network quality of a plurality of streams in the first application, and when the electronic equipment monitors that the quality of a certain stream of the first application is poor, switching a plurality of streams of the first application including the stream with poor quality to a standby network channel, so that the plurality of streams of the network application are always borne on the network channel with relatively good quality, the transmission quality of the streams is ensured, the possibility of service blocking of the first application is reduced, and the user experience is improved.

It should be noted that if the electronic device has already enabled the standby network channel when deciding to switch the plurality of streams to the standby network channel, the electronic device switches the plurality of streams to the standby network channel that has already been enabled, and if the electronic device has not enabled the standby network channel when deciding to switch the plurality of streams to the standby network channel, the electronic device needs to enable one standby network channel first and then switch to the standby network channel that has been enabled.

Optionally, the acceleration start message may include information corresponding to the identity of the first application, for example, may include: the method comprises the steps of identifying a first application, a target flow type, a flow model corresponding to the target flow type, network quality evaluation parameter information and flow switching strategy information. Reference may be made specifically to the foregoing related description, which is 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 for notifying the traffic reporting component that the first application has been switched to the foreground, and instructing the traffic reporting component to monitor the data flow between the first application and the server.

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

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

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

Specifically, the flow level path management component requests the primary network channel from the channel level path management component upon receiving the channel enable message. In the embodiment of the application, the electronic device supports to use two SIM cards (a main card and a secondary card) simultaneously, and the two SIM cards open mobile data service, and the electronic device is connected with two WIFI network channels (a main WIFI network channel and a secondary WIFI network channel) simultaneously for illustration. Because the electronic equipment starts the mobile data service of the two SIM cards, and the electronic equipment is simultaneously connected with the two WIFI network channels, the electronic equipment is currently connected with the four network channels, and the four network channels are respectively: a primary WIFI network channel, a primary mobile data network channel, a secondary WIFI network channel, and a secondary mobile data network channel. The network channels corresponding to the main WIFI, the main SIM card, the auxiliary WIFI and the auxiliary SIM card are sequentially as follows: a primary WIFI network channel, a primary mobile data network channel, a secondary WIFI network channel, and a secondary mobile data network channel.

After the first application is started, the flow-level path management component can sequentially request the main WIFI network channel, the main mobile data network channel, the auxiliary WIFI network channel and the auxiliary mobile data network channel as the main network channel, if the network channel currently requested by the flow-level path management component 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 takes the network channel as the main network channel and does not request the network channel any more, otherwise, the flow-level path management component sequentially requests the main network channel from the channel-level path management component according to the sequence 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 not performed. For example, the flow-level path management component requests the channel-level path management component for the primary WIFI network channel as the primary network channel, if the primary WIFI network channel is available, the primary WIFI network channel is taken as the primary network channel, and the flow-level path management component no longer requests the primary mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel as the primary network channel. And if the main WIFI network channel is unavailable, sequentially requesting the main network channel according to the order of the main mobile data network channel, the auxiliary WIFI network channel and the auxiliary mobile data network channel until one network channel is found to be used as the main network channel. If none of the four network channels is available, the first application fails to accelerate the network, and the first application is not accelerated, i.e. the network channels of the first application are switched.

It should be understood that, the flow-level path management component may request the channel-level path management component for the main network channel according to the sequence of the main WIFI network channel, the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel, and may request the main network channel according to other sequences, for example, the flow-level path management component may request the channel-level path management component for the main network channel according to the sequence of the main WIFI network channel, the secondary WIFI network channel, the main mobile data network channel, and the secondary mobile data network channel, which 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 channels is also related to the number of network channels to which the electronic device is connected, for example, in the case that the electronic device is only connected to the main WIFI network, and the main SIM card mobile data service and the auxiliary SIM card mobile data are opened, the electronic device is only connected to the main WIFI network channels, the main mobile data network channels, and the auxiliary mobile data network channels, and the order in which the flow-level path management component requests the main network channels from the channel-level path management component may be the order of the main WIFI network channels, the main mobile data network channels, and the auxiliary mobile data network channels, or may be the order based on other combinations of the three network channels. The number of network channels connected with the electronic device and the order in which the channel-level path management component requests the main network channels from the channel-level path management component based on the network channels connected with the electronic device are not limited.

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

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

Specifically, when the channel-level path management component receives the main network channel request sent by the stream-level path management component, the channel-level path management component determines whether the main network channel currently requested by the stream-level path management component is available. If not, the channel-level path management component returns a message to the stream-level path management component, the message being used to notify the stream-level path management component that the requested primary network channel is not available, so that the stream-level path management component applies for other network channels as primary network channels.

It should be appreciated that after the first application is launched, the channel-level path management component may periodically record the availability of all network channels to which the electronic device is connected after the channel-level path management component sends a primary network channel request to the channel-level path management component.

Step S609: in the case where the primary network channel currently requested by the flow level path management component is an available network channel, the channel level path management component requests enablement of the primary network channel from the network connection component.

For example, if the flow-level path management module requests the channel-level path management module to use the main WIFI network channel as the main network channel, and the channel-level path management module determines that the main WIFI network channel is available, the channel-level path management module may request the network connection module to enable the main WIFI network channel, so that a data flow between the first application and the server may be transmitted on the main WIFI network channel.

Step S610: the network connection management component enables the primary network channel and feeds back a notification message to the channel-level path management component that the primary network channel is enabled.

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

Specifically, after receiving the notification message that the primary network channel is enabled, the channel-level path management module requests the channel quality detection module to perform quality detection on the currently enabled primary network channel.

By way of example, the quality of the primary network channel may be detected based on at least one of the following parameters of the network channel: time delay, packet loss rate, bandwidth, rate, etc. of the channel. For example, the quality detection may be detecting Round-Trip Time (RTT) of the primary network channel.

Optionally, when there is a history of the currently enabled primary network channel, that is, the currently enabled primary network channel is once enabled, at this time, the quality of the primary network channel may be evaluated in combination with the RTT and the history, where the history may include a history of a receiving rate, a number of times that the channel quality is poor, and the embodiment of the present application does not specifically limit the manner of evaluating the 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, and if the network quality of the currently enabled main network channel does not meet the requirement, the channel level path management component performs step S609, namely: the channel-level path management module requests starting of available network channels from the network connection channels based on the order in which the stream-level path management module requests the main network channels (excluding the currently enabled network channels) until a network channel with network quality meeting the requirement is found as the main network channel. If a main network channel with the network quality meeting the requirement is not found, the acceleration of the first application fails and the first application is not accelerated.

For example, the currently enabled primary network channel is a primary WIFI network channel, the available network channels include a primary WIFI network channel, a primary mobile data network channel, a secondary WIFI network channel, and a secondary mobile data network channel, and the order in which the stream level path management component requests the available primary network channels is the primary WIFI network channel, the primary mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel. If the network quality of the current enabled main network channel (main WIFI network channel) does not meet the requirement, the channel-level path management component applies for enabling the main mobile data network channel to serve as the main network channel to the network connection component, 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 requirement, the channel-level path management component does not request the network connection component for an available main network channel any more, otherwise, the channel-level path management component sequentially requests the network connection component for the auxiliary WIFI network channel and the auxiliary mobile data network channel to serve as the main network channel, enables the auxiliary WIFI network channel and the auxiliary mobile data network channel, and then detects the network quality of the auxiliary WIFI network channel until an available network channel with the network quality meeting the requirement is found to serve as the main network channel, and enables the auxiliary WIFI network channel, so that the data stream of the first application and the application program can be transmitted on the main network channel.

Step S613: the policy management component sends a traffic probe request to the traffic awareness component.

In particular, the flow probe request may be used to instruct the flow aware component to initiate message statistics and monitoring of network applications on the primary network channel. The traffic detection request may include an identity (e.g., UID) of a first application to be detected currently, and is configured to request detection and monitoring of a data flow between a network application and a server on the primary network channel, where the network application and the server correspond to the identity. It will be appreciated that the data stream may be in the form of messages.

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 flow sensing component sends a flow reporting request to the flow reporting component.

Specifically, after the flow sensing component receives the flow detection request sent by the application level policy management component, the flow sensing component may send a flow reporting request to the flow reporting component, where the flow reporting request may be used to instruct the flow reporting component to detect a data flow transmitted between the first application and the server on the current main network channel, and report the detected data flow. It will be appreciated that the traffic probe request may contain an identity (e.g., UID) of the first application.

Step S615: the flow reporting component detects the flow and reports the message statistical information of the target flow to the flow sensing component.

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

In a specific implementation, the flow reporting component may obtain, by using a calling component (e.g., netfilter component of the android system), a message of the target flow on the current main network channel. It should be understood that the Netfilter component is merely illustrative and not limiting to embodiments of the present application, and in some embodiments, detection of the target flow may be accomplished by other components.

Because the message monitoring hook is registered in advance by the flow reporting component, when the flow reporting component detects the flow, the message of the target flow can be acquired through the message monitoring hook. As shown in fig. 7, the overall implementation block diagram is that Netfilter hooks an nf_hook function of a flow reporting component, a message carried on a current main network channel enters the flow reporting component, the flow reporting component stores a message of a target flow into an SKB queue through processes such as message analysis, flow table creation, message content analysis and the like, and for the message in the SKB queue, according to a reporting policy of the target flow to which the message belongs, the message statistical information of the target flow which needs to be reported at fixed time is triggered by a timer to be reported to a flow sensing component.

Referring to fig. 7, a specific implementation flow of the message reporting component may include:

step S1, initializing;

when the first application is started and loaded, the flow reporting component receives the second notification message in step S606, and registers the message monitoring hook function.

S2, message processing;

the method specifically comprises three steps of message analysis, flow checking and message analysis. The flow table records identification information of flows in each network application and statistical information of each flow, and the statistical information of each flow may include: the number of messages of the received stream, the total number of bytes of the messages of the received stream, the number of erroneous packets, etc. The identification information of the stream can be obtained by calculation according to the quintuple or the tetratuple of the message in the stream, and the calculation can specifically use a hash algorithm, so that the identification information of the stream can be a hash value obtained by calculation of the quintuple or the tetratuple of the message.

When the message is analyzed, the flow reporting component acquires the message and can analyze whether the UID of the first application exists in the message; if so, the message is a message of the first application, a quadruple (or five-tuple) of the message is analyzed, and a subsequent flow table checking step is executed; if not, the message is not the message of the first application, and the process is ended. The quadruple 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 looking up the flow table, the identification information of the flow can be calculated according to the quadruple (or five-tuple) of the message, whether the identification information is recorded in the flow table or not is searched by using the identification information obtained by calculation, and if so, the statistical information corresponding to the identification information in the flow table is updated; if not, creating a flow node in the flow table according to the identification information of the flow, and updating the statistical information of the flow in the flow node.

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

And S3, reporting the matched target flow and the statistical information of the target flow message to a flow sensing module according to the flow reporting strategy.

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

Specifically, the flow reporting component periodically reports statistical information of the target flow message to the flow sensing component, and periodically detects network quality of the target flow between the first application and the server. Next, with reference to fig. 8, a specific description will be given of a flow of detecting network quality by the flow sensing component in units of one cycle, where the specific flow is as follows:

step S801: the flow sensing component receives the statistical information of the target flow message in the period reported by the flow reporting component.

Specifically, the flow reporting component detects a data flow between the first application and the server, the data flow is a target data flow, statistics is performed on uplink messages and downlink messages in the target data flow by taking a period as a unit, and the statistics information of the target flow messages is sent to the flow sensing component. The statistical information of the target flow message includes not only: the number of the uplink messages, the number of the downlink messages, the protocol number of each message, the byte number of the message, the source IP address of the message, the destination IP address of the message and the like.

Step S802: the flow sensing component judges whether the first application is in a state of suspending/stopping downloading according to the message statistical information based on the period.

Specifically, the flow sensing component may obtain downlink network rates of the current period and a plurality of past periods from packet statistics of the target flows of the current period and the past period, and determine that the first application is in a suspended download/stop download state based on the plurality of downlink network rates. The downloading state of the first application is a state that the server sends downlink data flow to the first application. The method for judging whether the first application is in the state of suspending downloading/stopping downloading by the flow sensing component based on the downlink network rate can be as follows: if the downlink network rate is greater than the first rate value and less than threshold in the current period, and the network quality record of the previous period is excellent, the flow sensing component judges that the first application is in a downloading suspension/downloading suspension state, and does not record the network quality of the current period. Otherwise, the first application is not in a suspended download/stop download state. And if the downlink network rate of the current period is smaller than the threshold, the network quality of the current period is recorded as poor, and the threshold is larger than the first rate value. The first rate value may be derived from historical data, may be derived from experimental data, and is not limited in this embodiment.

It should be understood that the method that the flow sensing component determines that the first application is in the state of suspending/stopping downloading based on the packet statistics information of the current period in the embodiment of the present application is merely illustrative, and is not limited.

If the first application is in the suspended/stopped downloading state, the flow sensing component executes step S803, and if the first application is not in the suspended/stopped downloading state, the flow sensing component executes step S804.

Step S803: the flow sensing component sets the download end flag to a first flag.

Specifically, the download end flag is used for indicating a download state of the first application, if the download end flag is the first flag, the flow sensing component determines that the first application is in a downloading suspension/stopping state, and if the download end flag is not the first flag, the flow sensing component determines that the first application is not in the downloading suspension/stopping state. For example, the first identifier may be a character such as "True" or "1", and the method for representing the first identifier is not limited in the embodiments of the present application.

Step S804: the flow sensing component judges whether the downloading end mark is a first mark.

Specifically, if the determination is yes, the flow sensing component executes step S806, and if the determination is no, the flow sensing component executes step S805.

Step S805: the flow sensing component records the network quality of the present period based on the message statistical information of the present period.

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

Step S806: the flow sensing component does not record the network quality for the present period.

Step S807: and under the condition that an uplink message exists, the flow sensing component judges whether the network protocol of the uplink message is a GQUIC protocol based on the message statistical information of the period.

Specifically, as described in step S615, in the process of detecting the target flow, the flow reporting component may parse the packet in the target flow, so as to obtain the network protocol used by the packet in the target flow. After capturing the message, the flow reporting component judges whether a CHLO (Client Hello) field exists in the uplink message, if yes, the network protocol used by the message is judged to be GQUIC protocol, and if yes, the flow reporting component records the network protocol in the message statistical information of the target flow. Fig. 9 is a schematic diagram of a datagram using gqic protocol according to an embodiment of the present application, and as can be seen from fig. 9, the datagram contains a choo field.

The flow sensing component judges whether the network protocol of the uplink message in the current period is the gqic protocol based on the message statistical information of the target flow, if yes, step S808 is executed, if no, the flow is ended.

Step S808: the flow sensing component determines whether the upstream data message is an ACK message using the gqic protocol.

Specifically, if the network protocol used by the flow sensing component in the current period is determined to be the gqic protocol, the flow sensing component determines whether the uplink data packet is an ACK packet, if yes, it indicates that the uplink data packet is not a download request packet, the network quality detection flow in the current period is completed, the flow is ended, and if no, step S809 is executed. The flow sensing component may determine whether the uplink packet is an ACK packet according to the Byte length of the payload field in the uplink packet, if the Byte length of the payload field is greater than or equal to a first threshold (e.g., 300 Byte), the uplink packet is not the ACK packet, and if the Byte length of the payload field is not the ACK packet, the uplink packet is a download request packet, otherwise, the uplink packet is the ACK packet. The first threshold may be obtained from an empirical value, may be obtained from historical data, or may be obtained from experimental data, which is not limited in the embodiment of the present application.

For easy understanding, in the following, a detailed flow of determining whether the uplink message is an ACK message by the flow sensing component in the steps S807-S808 is described with reference to fig. 10, and referring to fig. 10, a flow of determining whether the uplink message is an ACK message by the flow sensing component provided in the embodiment of the present application is as follows:

step S1001: the flow sensing component determines whether the CHLO field exists in the upstream message. If the determination is yes, step S1002 is executed, and if the determination is no, it is determined that the network protocol used in the uplink packet is not the gqic protocol, and step S1005 is executed.

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

Step S1003: the flow sensing component judges whether the byte length of the payload field of the uplink message is greater than or equal to a first threshold. If not, step S1004 is executed, and if yes, step S1005 is executed.

Step S1004: the flow sensing component determines the uplink message as an ACK message.

Step S1005: the flow sensing component determines that the uplink message is not an ACK message.

Step S809: the flow sensing component sets the download end flag to a second flag.

Specifically, if the uplink datagram in the current period is not an ACK message using the gqic protocol, the download end flag is set to the second flag, so that the flow sensing component determines whether to record the network quality according to the download end flag in the next period. As shown in fig. 11, in period 1 to period 3, the first application is in a downloading state, that is, the server sends a downlink data stream to the first application, the flow sensing component determines that the downloading process is suspended in period 4, sets the downloading end flag as the first flag, sets the downloading end flag in period 5 to period 6 as the first flag, but in period 6, the flow sensing component detects that there is an uplink downloading request message, which indicates that the downloading of the first application is restarted, the flow sensing component sets the downloading end flag as the second flag, and in period 7, the flow sensing component determines whether to record the network quality of the current period based on the downloading end flag, and if the downloading end flag is not the first flag, records the network quality of the current period.

Next, a specific flow of determining whether to switch a network channel by the traffic sensing component based on the network quality of each period recorded by the traffic sensing component will be described with reference to fig. 12, where the specific flow is as follows:

Step S1201: the flow sensing component obtains network quality detection results of the first M periods adjacent to the current period.

Step S1202: and judging whether the network quality detection result of more than N periods is poor in the network quality detection results of the flow sensing component in the M periods. If yes, step S1203 is executed, and if no, step S1204 is executed.

In some embodiments, when the counted period is less than M, the network quality detection result is poor according to whether the counted period number P exceeds (n×p)/M periods. If yes, step S1203 is executed, and if no, step S1204 is executed.

In step S1203, the flow sensing component determines to switch network channels.

Step S1204: the traffic awareness component determines not to switch network channels.

It should be understood that in the embodiment of fig. 12, the method that the flow sensing component determines whether to switch the network channel based on the network quality detection result is merely illustrative, and the embodiments of the present application are not limited to other methods that the flow sensing component determines whether to switch the network channel based on the network quality detection result.

Step S617: in the case of determining to switch network channels, the flow awareness component sends network channel switching instructions to the flow level path management component.

Specifically, in the case of determining to switch network channels, the flow awareness 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 initiate a service for network channel switching.

Optionally, the channel switch instruction includes an identity of the first application (e.g., a 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 a channel switching instruction sent by the flow sensing component, the flow-level path management component requests to enable the standby network channel from the channel-level path management component.

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

Specifically, the channel-level path management component selects a network channel other than the primary 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, where all the four network channels are available, the main network channel is the main WIFI network channel, and then the channel-level path management component may select one network channel from the main mobile data network channel, the secondary WIFI network channel, and the secondary mobile data network channel as the standby network channel.

Step S620: the network connection management component initiates the standby network channel and feeds back a notification message to the channel-level path management component that the standby network channel is enabled.

Specifically, the method for enabling the standby network channel refers to enabling the standby network channel to be switched from a dormant state to an awake state, so that when the network channel is required to be switched subsequently, the standby network channel can be switched from the current network channel to the standby network channel quickly. For example, the standby network channel is a main mobile data network channel, and the network connection component starts the main mobile data network channel by switching the main mobile data network channel from the dormant state to the awake 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-step S612 from step S621-step S622, which are not described herein.

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 network channels.

Specifically, after receiving the notification of network channel switching 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 standby network channel for transmission.

In the embodiment of the application, after detecting that the application sends the download request message to the server, the electronic device periodically detects whether the network quality and the download process are finished/paused, if so, the electronic device does not take the downlink network rate in the period as a reference factor for judging whether the network quality is good or bad, and meanwhile, the electronic device can identify whether the uplink datagram sent by the application to the server in the period is the download request datagram, if so, the electronic device sets the download finishing flag bit as the download state, and by adopting the method, the electronic device is prevented from identifying the ACK confirmation message sent by the application to the server as the download request message after stopping or pausing the download process, and further takes the downlink network rate after receiving the confirmation message as a reference factor for judging whether to switch the network channel, thereby causing the wrong switching of the network channel.
