Description

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 method for detecting network quality and a related electronic device.

Background

With the rapid development of electronic technology and internet technology, mobile devices such as mobile phones and the like are increasingly applied in daily life of people, for example, mobile payment, games and the like can be performed through the mobile phones. In order to ensure normal operation of common services (e.g., games, conversations, social software, etc.), a user's mobile phone is typically connected to a wireless network. Network acceleration is typically performed in the case of poor network quality. However, in the process of surfing the internet by a user, the network quality detection is often inaccurate, and under the condition of inaccurate network quality detection, the problem of network miscut can occur, which may cause the user to use a large amount of data traffic to accelerate the network, and under the condition of insufficient user data traffic package, the package limit of the user may be exceeded, so that the user needs to pay extra telephone charges, thereby reducing the internet experience of the user.

Disclosure of Invention

The embodiment of the application provides a network quality detection method, which solves the problem that a network channel is switched mistakenly in the network acceleration process due to inaccurate network quality detection results.

In a first aspect, an embodiment of the present application provides a method, including: responding to a first operation of a user, and starting a first application; periodically receiving message statistical information of a target flow; 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 the state of suspending downloading/stopping downloading 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 a 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, and 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 download suspension/download completion state, the electronic device does not record the network quality. By the method, the problem that the electronic equipment mistakenly switches the network channel of the first application due to the fact that the electronic equipment mistakenly judges the uplink message as the downloading request message and continuously detects the network quality after the downloading is finished under the state that the first application pauses/finishes the downloading can be solved, the network quality detection result is inaccurate, the inaccurate network detection result is used as a reference factor for judging whether the network channel is switched or not by the electronic equipment, and the network channel of the first application is mistakenly switched by the electronic equipment.

In one possible implementation, the method further includes: and under the condition that the uplink message is the ACK message, judging whether the uplink message of the next period is the ACK message.

In a possible implementation manner, determining whether the uplink packet is an ACK packet based on the packet statistical 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 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 greater than or equal to a first threshold value; if the uplink message is larger than or equal to the 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. Therefore, the electronic equipment can distinguish the uplink message as the ACK message or the download request message, so that the phenomenon that the electronic equipment wrongly judges the uplink message as the download request message and continuously detects the network quality after the download is finished to cause inaccuracy of a network quality detection result when the first application is in a state of suspending/finishing the download can be avoided, the inaccurate network quality detection result is used as a reference factor for judging whether to switch the network channel by the electronic equipment, and the network channel of the first application is wrongly switched by the electronic equipment.

In a possible implementation manner, determining whether a network protocol of the uplink packet is a GQUIC protocol based on packet statistics information includes: judging whether the uplink message has a CHLO field; if the CHLO field exists, determining that the network protocol of the uplink message is a GQUIC protocol; and if the CHLO field does not exist, determining that the network protocol of the uplink message is not the GQUIC protocol. Therefore, whether the network protocol of the uplink message is the GQUIC protocol or not is judged through the CHLO field, and whether the uplink message is the ACK message or not can be further judged under the condition that the network protocol is the GQUIC protocol.

In a possible implementation manner, the network quality is obtained based on the downlink network rate in the message statistical information of the current period; if the downlink network rate is less than or equal to a preset rate threshold, recording the network quality of the current period as poor; and if the downlink network rate is greater than the preset rate threshold, the network quality record of the current period is excellent. Therefore, the electronic equipment can judge whether to switch the network channel based on the network quality, so that the situation that the first application is blocked in service is avoided, and the internet experience of a user is reduced.

In a possible implementation manner, after the determining, based on the message statistical information of the current period, whether the uplink message is an ACK message, the method further includes: acquiring the network quality of M periods adjacent to the current period under the condition that the number of the current statistical period is greater than M; judging whether the network quality exceeding N periods is poor in the M periods; if the judgment result is 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 number of the current statistical periods is less than or equal to M, acquiring the network quality of all P periods adjacent to the current period; judging whether the network quality of the P periods exceeds (P x N)/M periods is poor; if yes, determining to switch the network channel of the first application; and 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 situation that the first application is blocked in service is avoided, and the internet experience of a user is reduced.

In a possible implementation manner, after determining that the uplink packet is not the ACK packet based on the packet statistical information of the current period, before recording a period of network quality, the method further includes: and setting the downloading end mark as a second identifier, wherein the second identifier is used for representing that the first application is in a downloading starting state. Therefore, the electronic equipment can judge whether to record the network quality in the next period.

In a possible implementation manner, when it is determined that the first application is in the suspend/stop downloading state based on the message statistical information of the current period, the method does not record the network quality of the current period, and includes: 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 identifier is used for indicating that the first application is in a pause downloading/stop downloading state.

In a possible implementation manner, when determining that the download ending flag is the first flag based on the packet statistical information of the current period, before not recording the network quality of the current period, the method further includes: the message statistical information of the current period judges whether the downloading end mark is set as the first mark; if the judgment result is yes, setting a downloading end mark as the first mark; and judging whether the downloading end mark is the 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 conjunction with fig. 2 to fig. 3F.

Fig. 2 is a diagram of an indoor network connection scenario provided in an embodiment of the present application, where the indoor scenario is a user living room. The router 101 is included in the user living room, the router 101 is connected with the network to send out WIFI signals, so that the electronic device 100, the television 103 and the intelligent air conditioner 104 in the living room can be connected with the network through the WIFI signals transmitted by the router 101, and the electronic device 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, assuming that the coverage of the WIFI signal transmitted by the router 101 is only the living room, and the network quality of the electronic device 100 after connecting to WIFI deteriorates as the distance between the electronic device 100 and the router 101 increases.

Next, an application scenario of the electronic device performing network channel switching due to network quality degradation in a process of online watching a video by a user is described with reference to fig. 3A to 3F, where fig. 3A to 3F are exemplary interfaces for a group of users to online watch a video using the electronic device 100 according to an embodiment of the present application.

Fig. 3A is a user interface 10 of the electronic device 100, where 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. As shown in fig. 3A, the electronic device 100 is currently connected with the WIFI network channel, the main mobile data network channel (a network channel corresponding to the main SIM card) and the auxiliary mobile data network channel (a network channel corresponding to the auxiliary SIM card) by the WIFI network icon 301, and the mobile data icon 302 is used for indicating that the electronic device 100 is connected with the mobile data network channel, and it is assumed that the electronic device 100 has the main SIM card and the auxiliary SIM card and both of the two SIM cards start a mobile data service. In the embodiment of the present application, the electronic device 100 takes the WIFI network channel as a main network channel, and the network channel enabled by the electronic device 100 is taken as the main network channel. The network speed display icon 304 is used to display a downlink rate of a 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 apparatus 100 detects a one-click input operation to the video application icon 303, the electronic apparatus 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, a video cover 311 currently displayed by the video recommendation area is "pet's story", and when the electronic device 100 detects a single-click input operation for the video cover 311, the electronic device 100 displays the user interface 30 shown in fig. 3C.

As shown in fig. 3C, the user interface 30 is an interface for playing a video, and as can be seen from fig. 3C, the network channel currently enabled by the electronic device 100 is a 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.

As shown in fig. 3D, in the process of watching the video, the user moves the electronic device 100 from the active area 1 to the active area 2, then moves the active area 2 to the active area 3, and turns on the air conditioner, and the distances between the active area 1, the active area 2, and the active area 3 and the router 101 decrease in sequence. 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. As shown in fig. 3E, since the network quality of the electronic device 100 in the active area 2 is worse than that in the active area 1, the network speed of the electronic device 100 is reduced compared to that in the active area 1, and when the user moves to the active area 3, the electronic device 100 displays the user interface 50 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, and the network acceleration prompt box 501 is used to prompt that the network acceleration of the video application is started. For example, the network acceleration prompt box 501 in fig. 3F displays information of "switching of network channels is completed and network acceleration is performed". It can be seen in the user interface 50 that the network channel enabled by the current video application is a standby network channel, the current network speed is 1.8M/s, and the playing progress of the current video is 06. The electronic device 100 completes the switching from the main network channel to the standby network, and the network rate of the electronic device is greatly increased after the electronic device switches from the active area 3 to the standby network channel, compared with the network rate in the active area 2.

It should be understood that fig. 3A-3F above illustrate an exemplary set of user interfaces for switching network channels of an electronic device during playing a video, which are caused by a change in the linear distance between the electronic device and a router, and the electronic device switches network channels based on the detected network quality, and the embodiments of the present application are not limited thereto.

Fig. 2 to fig. 3F describe application scenarios of the electronic device for performing 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 moves from the active area 2 to the active area 3, the linear distance between the electronic device and the router is continuously increased, which causes the network quality to be deteriorated, and further causes the network rate of the electronic device to be 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.

As shown in fig. 4, the electronic device transmits data streams with a server through a WIFI network channel, where the WIFI network channel includes a plurality of stream channels (only two stream channels are listed in the figure), where the stream channel a is used to transmit an upstream data stream from an application 1 to the server, and the stream channel B is used to transmit a downstream 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 network quality of a downlink data stream (for example, transmission rate of the downlink datagram, delay of the datagram, packet loss rate, and the like), and when detecting that the network quality of the data stream is degraded, switches the data stream between the application 1 and the server to a mobile data network channel for transmission.

The application 1 and the server generally use a UDP protocol to transmit messages, the application 1 firstly sends an uplink downloading request message to the server for communicating with the server, after receiving the uplink downloading request message, the server sends a downlink data stream to the application 1, at the moment, the electronic equipment is triggered to carry out message detection on the downlink data stream, so that the network quality of the current data stream is detected, and whether network channel switching is needed or not is judged according to the network quality. After the server finishes sending the downlink data stream, the electronic device 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 uses a protocol such as GQUIC to transmit an upstream message, the server transmits a downstream data stream to the application 1 after the application 1 transmits an upstream download request message to the server. 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 such an acknowledgement message is only used to notify the server, and the application 1 has received the downlink data stream sent by the server, and has no other role. The electronic device usually detects the 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 the application 1, so that the accuracy of the downlink rate is not affected by sending an acknowledgement message such as an uplink ACK or the like from the application 1 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 detection result of the network quality is not affected, but after the server stops/suspends sending the downlink data stream to the application 1, if the application 1 sends the uplink acknowledgement message to the server, and the electronic device cannot identify the uplink acknowledgement message, the uplink acknowledgement message is taken as the download request message, so that the downlink network rate after receiving the uplink acknowledgement message is taken as a factor of the network quality by the electronic device, the result of the network quality detection by the electronic device is inaccurate, and the situation of network channel false switching is caused. If the WIFI network channel is switched to the mobile data network channel by the electronic equipment, a large amount of mobile data traffic can be consumed due to network acceleration, and for some users with small total package flow or small residual flow, the traffic can exceed the package limit, so that the users can pay more telephone charges exceeding the package limit, and bad use experience is brought to the users.

In order to solve the problem that the detection result of the network quality of the electronic device is inaccurate and the network channel is miscut due to the fact that the electronic device cannot recognize the ACK or other acknowledgement messages, the embodiment of the present 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 according to an embodiment of the present application, where the specific flow is as follows:

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

Specifically, a user opens a first application in the 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 single click) for a video application icon, a video application is launched. It is to be understood that the foregoing embodiments are merely illustrative of a scenario in which the first application (video application) is started by clicking, and do not constitute a limitation to the embodiments of the present application, and in some embodiments, the first application may also be started by other operation manners (for example, double-click, sliding, and the like).

The first application is a network application, that is, an application that needs 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, or the like.

Step S602: and after detecting that the first application is switched to the foreground, the environment perception component sends a first notification message to the policy management component.

Specifically, an environment detection component in the service layer of the electronic device may detect a state of the first application, and send a first notification message to the policy management component when the environment sensing component detects that any application is switched to a foreground. The first notification message is used for notifying the policy management component that the first application is switched to the foreground. The first notification message comprises an identity of the first application, and the identity is used for identifying the unique identity of the first application.

Step S603: 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 receiving the first notification message, the application-level policy management component may know that the first application is switched to the foreground, and then, the application-level policy management component determines whether the first application satisfies a condition for starting network acceleration by querying the application configuration library. The application configuration library comprises configuration information of all application programs of the electronic equipment, and the configuration information comprises but is not limited to whether each application program is granted the authority of network acceleration. The policy management component acquires configuration information of the first application in an application configuration library based on the identity of the first application, and determines whether the first application has the network acceleration authority, 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, acceleration traffic for the first application may be started, and an acceleration enabling message indicating that the flow-level path management component may start the acceleration traffic for the first application is sent to the flow-level path management component.

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

It should be noted that, if the electronic device already activates the standby network channel when deciding to switch the multiple streams to the standby network channel, the multiple streams are switched to the activated standby network channel, and if the electronic device does not activate the standby network channel when deciding to switch the multiple streams to the standby network channel, the electronic device needs to activate one standby network channel first and then switch to the activated standby network channel.

Optionally, the accelerated start message may include information corresponding to the identity of the first application, and for example, the information may include: the first application comprises an identity of the first application, a target flow type, a flow model corresponding to the target flow type, network quality assessment parameter information and flow switching strategy information. Reference may be made to the foregoing description, which is not repeated herein.

Step S605: and the flow level path management component sends a second notification message to the flow 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: and after the flow reporting component receives the second notification message sent by the flow-level path management component, registering 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 a first application and a server in a network channel.

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

Specifically, after the stream level path management component receives the channel enable message, the stream level path management component requests the channel level path management component for the main network channel. In the embodiment of the application, an example is given in which an electronic device supports simultaneous use of two SIM cards (a main card and an auxiliary card), the two SIM cards start a mobile data service, and the electronic device is connected to two WIFI network channels (a main WIFI network channel and an auxiliary WIFI network channel) at the same time. Because the electronic equipment starts the mobile data service of the two SIM cards, and the electronic equipment is connected with the two WIFI network channels at the same time, the electronic equipment is currently connected with the four network channels, which are respectively: the mobile terminal comprises a main WIFI network channel, a main mobile data network channel, an auxiliary WIFI network channel and an auxiliary mobile data network channel. Wherein, the network channel that main WIFI, main SIM card, vice WIFI, vice SIM card correspond does in proper order: the mobile terminal comprises a main WIFI network channel, a main mobile data network channel, an auxiliary WIFI network channel and an auxiliary mobile data network channel.

After the first application is started, the stream level path management component can request the main WIFI network channel, the main mobile data network channel, the auxiliary WIFI network channel and the auxiliary mobile data network channel in sequence 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 data streams between the first application and the server), the stream level path management component takes the network channel as the main network channel and does not request the network channel any more, otherwise, the stream level path management component sequentially requests the channel level path management component for the main network channel according to the sequence until an available network channel is found. If no available network channel is 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 channel-level path management component that the main WIFI network channel is 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 does not request the main mobile data network channel, the auxiliary WIFI network channel, and the auxiliary mobile data network channel to be the main network channel. And if the main WIFI network channel is unavailable, sequentially requesting the main network channel according to the sequence 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 network acceleration of the first application fails, and the network acceleration of the first application is not performed, that is, the network channel of the first application is switched.

It should be understood that, the stream-level path management component may request the channel-level path management component for the main network channel in sequence according to the sequence of the main WIFI network channel, the main mobile data network channel, the auxiliary WIFI network channel, and the auxiliary mobile data network channel, and may also request the main network channel according to other sequences, for example, the stream-level path management component may request the channel-level path management component for the main network channel in sequence according to the sequence of the main WIFI network channel, the auxiliary WIFI network channel, the main mobile data network channel, and the auxiliary mobile data network channel, which is not limited in this embodiment of the present application.

For example, in the case that the electronic device is connected to only the main WIFI network, and the main SIM card mobile data service and the sub SIM card mobile data are turned on, the electronic device is connected to only the main WIFI network, the main mobile data network, and the sub mobile data network, and the order in which the flow level path management component requests the main network from the flow level path management component may be the main WIFI network, the main mobile data network, and the sub mobile data network, or may be an order based on other combinations of the three network channels. The number of network channels connected with the electronic device and the order of requesting the main network channel from the channel-level path management component based on the network channels connected with the electronic device are not limited by the flow-level path management component in the embodiment of the application.

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

Step S608: the channel-level path management component judges whether a main network channel currently requested by the stream-level path management component is available.

Specifically, after the channel-level path management component receives a main network channel request sent by the stream-level path management component, the channel-level path management component may determine whether a main network channel currently requested by the stream-level path management component is available. If the main network channel is unavailable, the channel-level path management component returns a message to the flow-level path management component, wherein the message is used for notifying the flow-level path management component that the requested main network channel is unavailable, so that the flow-level path management component applies for other network channels to be the main network channel.

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

Step S609: in the case where 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 stream-level path management module requests the channel-level path management module for the main WIFI network channel to be 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 component may request the network connection component to enable the main WIFI network channel, so that the data stream 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 main network channel and feeds back a notification message that the main network channel is 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 primary network channel.

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

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

Optionally, when the currently enabled main network channel has a historical selection record, that is, the currently enabled network channel is enabled once, at this time, the quality of the main network channel may be evaluated by combining the RTT and the historical record, where the historical record may include a historical reception rate, historical times of poor channel quality, and the like.

Step S612: and 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, that is: the channel level path management module requests starting of available network channels from the network connection channel based on the sequence (excluding the currently enabled network channel) of the main network channel requested by the stream level path management module until finding a network channel with network quality meeting the requirement as the main network channel. If a main network channel with 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 main network channel is a main WIFI network channel, the available network channels include a main WIFI network channel, a main mobile data network channel, an auxiliary WIFI network channel, and an auxiliary mobile data network channel, and the order in which the flow level path management component requests the available main network channel is the main WIFI network channel, the main mobile data network channel, the auxiliary WIFI network channel, and the auxiliary 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 from 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 the available main network channel, otherwise, the channel level path management component sequentially requests the network connection component for enabling the auxiliary WIFI network channel and the auxiliary mobile data network channel to serve as the main network channel, and then detects the network quality until an available network channel with the network quality meeting the requirement is found to serve as the main network channel, and the network level path management component is enabled, so that the data stream of the first application and the application program is transmitted on the main network channel.

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

Specifically, the traffic probe request may be used to instruct the traffic awareness component to start message statistics and monitoring of the network application on the main network channel. The traffic detection request may include an identifier (e.g., UID) of a first application to be currently detected, and is used to request to detect and monitor data flow between the server and the network application corresponding to the identifier on the main network channel. It will be appreciated that the data stream may be in the form of a message.

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

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

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

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

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

In specific implementation, the traffic reporting component may obtain, through a call component (e.g., a Netfilter component of an android system), a packet of a target flow on a current main network channel. It should be understood that the Netfilter component is merely an exemplary component and does not constitute a limitation to the embodiments of the present application, and in some embodiments, the detection of the target flow may be accomplished by other components.

Because the flow reporting component registers the message monitoring hook in advance, when the flow reporting component performs flow detection, the message of the target flow can be acquired through the message monitoring hook. The overall implementation block diagram is shown in fig. 7, for example, the Netfilter hooks a packet to the nf _ hook function of the traffic reporting component, a message carried on the current main network channel enters the traffic reporting component, the traffic reporting component stores the message of the target stream into the SKB queue through the flows of message parsing, stream table creation, message content analysis and the like, and for the message in the SKB queue, the message statistical information of the target stream to be reported at regular time is triggered and reported to the traffic sensing component by the timer according to the reporting policy of the target stream to which the message belongs.

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

step S1, initializing;

when the first application starts loading, the traffic reporting component receives the second notification message in step S606, and registers the message monitoring hook function.

S2, processing the message;

the method specifically comprises three steps of message analysis, flow table lookup 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 received messages of the flow, the total number of bytes of the received messages of the flow, the number of error packets and the like. The flow identification information may be calculated according to a quintuple or a quadruple of the packet in the flow, and the calculation may specifically use a hash algorithm, so that the flow identification information may be a hash value calculated by the quintuple or the quadruple of the packet.

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 or not; if the message exists, the message is the message of the first application, the quadruple (or quintuple) of the message is analyzed, and the 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 quintuple can include: source IP, destination IP, source port, destination port, and protocol number.

When the flow table is searched, the identification information of the flow can be calculated according to the quadruplet (or quintuple) of the message, whether the identification information is recorded in the flow table or not is searched by using the calculated identification information, and if yes, the statistical information corresponding to the identification information in the flow table is updated; if not, a flow node is established in the flow table according to the identification information of the flow, and the statistical information of the flow in the flow node is updated.

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

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 traffic reporting component periodically reports the statistical information of the target flow packet to the traffic sensing component, and periodically detects the network quality of the target flow between the first application and the server. Next, with reference to fig. 8, a flow of detecting the network quality by the traffic sensing component in a unit of one period is specifically described, where the specific flow is as follows:

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

Specifically, the traffic reporting component detects a data flow between the first application and the server, where the data flow is a target data flow, and performs statistics on an uplink message and a downlink message in the target data flow by taking a period as a unit, and sends statistical information of the target flow message of the period to the traffic sensing component. The statistical information of the target flow packet includes, but is not limited to: the number of uplink messages, the number of 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 other information.

Step S802: and 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 traffic sensing component may obtain downlink network rates of the current period and the past periods from the packet statistical information of the target stream of the current period and the past period, and determine that the first application is in the suspend/stop downloading state based on the downlink network rates. The downloading state of the first application is a state that the server sends downlink data streams to the first application. The method for the traffic sensing component to determine whether the first application is in the suspend/stop downloading state based on the downlink network rate may be: 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 traffic sensing component judges that the first application is in a downloading suspension/stopping state, and does not record the network quality of the current period. Otherwise, the first application is not in a suspend/stop download state. The threshold is used for judging the network quality of the current period, if the downlink network rate of the current period is greater than or equal to the threshold, the network quality record of the current period is excellent, if the downlink network rate of the current period is less than the threshold, the network quality record of the current period is poor, and the threshold is greater than the first rate value. The first speed value may be obtained from historical data, may be obtained from experimental data, and is not limited in the embodiments of the present application.

It should be understood that, in the embodiment of the present application, the method for the traffic sensing component to determine that the first application is in the suspend/stop downloading state based on the message statistical information of the current period is merely exemplary and is not limited.

If the first application is in the state of suspending downloading/stopping downloading, the traffic sensing component performs step S803, and if the first application is not in the state of suspending downloading/stopping downloading, the traffic sensing component performs step S804.

Step S803: the traffic aware component sets the download complete flag to the first flag.

Specifically, the download ending flag is used to indicate a download state of the first application, and if the download ending flag is the first flag, the traffic sensing component determines that the first application is in a suspend/stop download state, and if the download ending flag is not the first flag, the traffic sensing component determines that the first application is not in the suspend/stop download state. For example, the first identifier may be characters such as "True" or "1", and the embodiment of the present application does not limit a representation method of the first identifier.

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

Specifically, if it is determined yes, the flow sensing component performs step S806, and if it is determined no, the flow sensing component performs step S805.

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

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

Step S806: the traffic aware component does not record the network quality for this period.

Step S807: and under the condition that the uplink message exists, the flow sensing component judges whether the network protocol of the uplink message is a GQUIC protocol or not based on the message statistical information of the period.

Specifically, as stated in step S615, in the process of detecting the target flow, the traffic reporting component may analyze 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 traffic reporting component judges whether a CHLO (Client Hello) field exists in the uplink message, then judges that the network protocol used by the message is a GQUIC protocol, and if the GQUIC protocol is used, the traffic reporting component records the message in the message statistical information of the target stream. Fig. 9 is a schematic diagram of a datagram using GQUIC protocol according to an embodiment of the present application, and as can be seen from fig. 9, the datagram includes a CHLO field.

And the flow sensing component judges whether the protocol number of the uplink message in the period is the GQUIC protocol or not based on the message statistical information of the target flow, if so, the flow sensing component executes the step S808, and if not, the flow sensing component ends the flow.

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

Specifically, the traffic sensing component determines whether the uplink data packet is an ACK packet or not when determining that the network protocol used by the packet in the present period is the GQUIC protocol, and if yes, it indicates that the uplink packet is not a download request packet, and the network quality detection process in the present period is completed, and ends the process, and if no, executes step S809. The traffic 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, and 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 an ACK packet, and the uplink packet is a download request packet, otherwise, the uplink packet is an ACK packet. The first threshold may be obtained from an empirical value, may also be obtained from historical data, and may also be obtained from experimental data, which is not limited in the embodiment of the present application.

For convenience of understanding, a detailed flow of determining whether the uplink message is an ACK message by the traffic sensing component in the above steps S807 to S808 is described below with reference to fig. 10, please refer to fig. 10, where fig. 10 is a flowchart of determining whether the uplink message is an ACK message by the traffic sensing component according to an embodiment of the present application, and a specific flow is as follows:

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

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

Step S1003: the traffic sensing component determines whether the byte length of the payload field of the uplink packet is greater than or equal to a first threshold. If it is determined not to be the case, step S1004 is executed, and if it is determined to be the case, step S1005 is executed.

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

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

Step S809: the traffic aware component sets the end of download flag to the second flag.

Specifically, if the uplink datagram in the current period is not an ACK packet using the GQUIC protocol, the download end flag is set to be the second identifier, so that the traffic sensing component determines whether to record the network quality in the next period according to the download end flag. 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 traffic sensing component determines that the downloading process is suspended in period 4, sets the downloading end flag to be the first flag, and sets the downloading end flag in period 5 to period 6 as the first flag, but in period 6, the traffic sensing component detects that an uplink downloading request message exists, which indicates that downloading of the first application is resumed, the traffic sensing component sets the downloading end flag to be the second flag, and in period 7, the traffic sensing component determines whether to record the network quality in the current period based on the downloading end flag, and if the downloading end flag is not the first flag, records the network quality in the current period.

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

step S1201: and the flow sensing component acquires the network quality detection results of the previous M periods adjacent to the current period.

Step S1202: and judging whether the network quality detection result exceeding N periods is poor or not 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 number of statistical cycles is less than M, the network quality detection result is poor according to whether the number of statistical cycles P exceeds (N × P)/M cycles. If yes, step S1203 is executed, and if no, step S1204 is executed

Step S1203, the traffic sensing component determines to switch the network channel.

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

It should be understood that, in the above embodiment of fig. 12, the method for determining, by the traffic sensing component, whether to switch the network channel based on the network quality detection result is merely an exemplary illustration, and the embodiment of the present application is not limited to other methods for determining, by the traffic sensing component, whether to switch the network channel based on the network quality detection result.

Step S617: in the event that a determination is made to switch network channels, the traffic aware component sends a network channel switch instruction to the flow level path management component.

Specifically, in the case of determining to switch the network channel, the traffic awareness component sends a network channel switching instruction to the flow level path management component, where the network channel switching instruction is used to indicate that the flow level path management component may 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 traffic awareness component, the flow-level path management component requests the channel-level path management component to enable the standby network channel.

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

Specifically, the channel-level path management component selects one of the currently available network channels other than the primary network channel as the backup network channel. For example, if the electronic device is connected to the main WIFI network channel, the main mobile data network channel, the auxiliary WIFI network channel, and the auxiliary mobile data network channel, the four network channels are all available, and the main network channel is the main WIFI network channel, then the channel-level path management component may select one network channel from the main mobile data network channel, the auxiliary WIFI network channel, and the auxiliary mobile data network channel as the standby network channel.

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

Specifically, the activating the standby network channel herein refers to switching the standby network channel from a sleep state to an awake state, so that the standby network channel can be quickly switched from the current network channel to the standby network channel when the network channel needs to be switched subsequently. For example, the standby network tunnel is a primary mobile data network tunnel, and the network connection component activates the primary mobile data network tunnel by switching the primary mobile data network tunnel from a dormant state to an awake state.

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

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

Specifically, please refer to steps S611 to S612 in steps S621 to S622, which are not described herein.

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

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

Step S625: the policy enforcement component switches network channels.

Specifically, after receiving a network channel switching notification sent by the stream level path management component to the policy execution component, the policy execution component switches the network channel, and switches the data stream between the first application and the server on the main network channel to the standby network channel for transmission.

According to the method, after the electronic equipment detects that the application sends the download request message to the server, the network quality and whether the download process is finished/suspended can be periodically detected, if the download process is finished/suspended in the period, the electronic equipment cannot use the downlink network speed in the period as a reference factor for judging the network quality, meanwhile, the electronic equipment can identify whether the uplink datagram sent by the application to the server in the period is the download request datagram, and if the uplink datagram is the download request datagram, the electronic equipment sets the download finishing flag bit to be in a download state.
