Description

[0001] This application trits the priority on the basis of a patent application in China No. 202110729329.1, filed in the National Department of Intellectual Property of China on June 29, 2021 and entitled “Method of Swimming of channels, electronic devices and data carriers” (“Channel Switching Method, Electronic DEVICE, AND STORAGE MEDIUM"), which is incorporated herein by reference in its entirety.

FIELDS OF TECHNOLOGY

[0002] Embodiments of this application relate to the field of communication technology and, in particular, to a channel switching method, an electronic device and a storage medium.

BACKGROUND OF THE ART

[0003] With the rapid development of electronic technology and Internet technology, mobile devices such as mobile phones are increasingly used in people's daily lives. For example, mobile payments and games can be performed using a mobile phone. To enable a shared service (such as games, calls, or social programs) to function properly, the user's mobile phone is typically connected to a wireless network. However, in some scenarios, the current wireless network cannot meet the service requirements (for example, if the mobile phone signal deteriorates), which may cause the service to stop. In this case, the user can activate the acceleration channel to satisfy the service requirements. However, switching the acceleration channel may result in relatively high latency and may also cause the service to stop, thereby degrading the user experience.

SUMMARY OF THE INVENTION

[0004] Embodiments of this application provide a channel switching method, an electronic device, and a storage medium to provide a method of switching from a primary network channel to a secondary network channel to improve handover efficiency and improve user experience.

[0005] According to a first aspect, an embodiment of this application provides a channel switching method, wherein the method is applied to an electronic device, the electronic device has a plurality of network channels, a first application is executed on the electronic device, a first application is transmitted over a first network channel, the first application includes itself with multiple packet streams, and the method includes:

in response to the monitored scenario change, detecting a second network channel based on the service type of the first application and determining a path of the second network channel based on the detection result, wherein the first application may be an Internet application such as a game, music or video; And

receiving first application packets over a first network link; and determining a characteristic packet stream from the plurality of packet streams of the first application, collecting statistics on packets in the characteristic packet stream to obtain a first statistical result, and switching the characteristic packet stream to a second network channel based on the first statistical result.

[0006] In this embodiment of this application, since a script change may cause the service to stop, by pre-detecting and maintaining a secondary network channel, after the service is identified, the service switches to the secondary network channel to shorten the time interval between identification and switching, thereby increasing the efficiency of channel switching.

[0007] In an exemplary implementation, the network channel includes at least a primary Wi-Fi channel, a secondary Wi-Fi channel, a primary cellular channel, and a secondary cellular channel.

[0008] In an exemplary implementation, the characteristic packet stream includes at least one of a download stream, a video stream, or a game stream.

[0009] In an exemplary implementation, the first application is a non-sensitive application, and the method further includes:

collecting statistics on packets of the characteristic packet flow of the first application to obtain a second statistical result and determining the quality of the first network channel based on the second statistical result;

detecting a second network channel based on the quality of the first network channel and determining a path of the second network channel based on the detection result; And

switching the characteristic packet flow to the second network channel.

[0010] In this embodiment of this application, since the insensitive application is insensitive to the moment of switching, the secondary network path does not need to be stored first, and the best network channel in another network channel needs to be directly discovered only after detecting that the quality of the network channel is deteriorating and the current The application directly switches to the best network channel, thereby increasing switching flexibility.

[0011] In an exemplary implementation, collecting statistics on packets of the first application's characteristic packet stream to obtain a second statistical result includes:

collecting statistical data about packets that are in the characteristic packet stream of the first application and that are received during a predetermined first duration to obtain a second statistical result.

receiving packets of the first application over the first network link for a predetermined second duration.

[0015] In this embodiment of this application, a predetermined second duration that is relatively short or equal to the predetermined first duration can be set to quickly determine whether a switch needs to be performed.

[0016] In an exemplary implementation, after switching the characteristic packet stream to the second network channel based on the first statistical result, the method includes:

carrying a non-characteristic stream of first application packets over a first network link.

[0017] In this embodiment of this application, only the characteristic packet stream is switched, and the non-characteristic packet stream is still carried on the primary network channel, thereby increasing the switching efficiency.

[0018] In an exemplary implementation, after switching the characteristic packet stream to the second network channel based on the first statistical result, the method includes:

switching the non-characteristic packet flow in the first application to a second network channel and disabling the first network channel.

[0019] In this embodiment of this application, all packet streams of the first application are switched to a secondary network channel, thereby improving the quality of all packet streams and further improving the user experience.

[0020] In an exemplary implementation, the method further includes:

removing the path of the second network link based on the first statistical result.

[0021] In this embodiment of this application, if the quality of the characteristic packet stream is found to meet the requirement after collecting the characteristic packet stream statistics, then the path of the second network channel can be removed, thereby saving resources and reducing power consumption of the electronic device.

[0022] In an exemplary implementation, removing the path of the second network link based on the first statistical result includes:

removing the second network link path after a predetermined fourth duration based on the first statistical result.

[0023] In this embodiment of this application, by setting a predetermined fourth duration, it can be ensured that, if the quality of the characteristic stream deteriorates, the characteristic stream can be timely switched to the secondary network channel within the predetermined fourth duration, so as to avoid that switchover cannot be performed because the secondary network link path has been deleted.

[0024] In an exemplary implementation, detecting a second network channel based on the service type of the first application and determining the path of the second network channel based on the discovery result includes:

detecting a round-trip packet delay of a second network channel based on the service type of the first application to obtain a detection result, the detection result including a round-trip packet delay of each network channel; And

[0025] In this embodiment of this application, the quality of the network channel can be quickly obtained by calculating the round-trip delay of the network channel.

[0026] In an exemplary implementation, the detection result further includes a historical record of each network channel.

[0027] In this embodiment of this application, by combining the round-trip delay and the historical record, the quality of the network channel can be obtained more accurately, so that the best secondary network channel can be selected more accurately.

[0028] In an exemplary implementation, collecting statistics on packets in a characteristic packet stream to obtain a first statistical result includes:

collecting statistics about the delay or packet loss ratio of the characteristic packet stream to obtain a first statistical result, the first statistical result being used to indicate whether the characteristic packet stream meets a predetermined delay requirement or a predetermined packet loss ratio requirement.

[0029] In this embodiment of this application, by calculating the delay or packet loss ratio of a characteristic packet stream, the quality of the characteristic packet stream can be quickly obtained so that a switching decision can be quickly made.

[0030] In an exemplary implementation, the electronic device further includes an acceleration sensor, and the scenario is obtained by detecting the acceleration sensor.

[00130] FIG. 3 is a flowchart of an embodiment of a channel switching method according to an embodiment of this application, wherein the method is applied to an electronic device 10, the electronic device 10 has a plurality of network channels, the first application is executed on the electronic device 10, the first application is transmitted over the first network channel, the first application includes a plurality of packet streams, and the method includes:

[00131] Step 301: In response to the monitored scenario, a second network channel is detected based on the service type of the first application, and a path of the second network channel is determined based on the detection result.

[00132] In particular, the scenario described above may be an environment in which the first device 10 is located. For example, the first device 10 is located in an environment (eg, an elevator) in which the network is relatively poor. When the first device 10 detects the environment in which the first device 10 resides in response to the monitoring scenario described above, the first device 10 may initiate a request to discover a second network channel, such that the secondary network channel (i.e., the second network channel) can be preliminarily saved.

[00133] Step 302: Receive packets of the first application on the first network channel.

[00134] Specifically, by detecting a second network channel, the first device 10 can obtain network information of the second network channel, wherein the network information may include a path of the second network channel. It can be understood that the second network channel is an available network channel such that the first device 10 can immediately switch to the second network channel upon detecting that the first network channel does not meet a service requirement, thereby reducing the switching delay.

[00135] After storing the path of the second network link, the packet flow of the first application can be further detected.

[00136] Step 303: Determine a characteristic packet stream from the plurality of packet streams of the first application, collect statistics on the packets in the characteristic packet stream to obtain a first statistical result, and switch the characteristic packet stream to a second network channel based on the first statistical result.

[00137] Specifically, the first device 10 can detect a packet stream of the first application in real time and can identify a characteristic packet stream in a plurality of packet streams. Statistical analysis of the packets in the characteristic packet stream may then be performed to obtain a first statistical result, wherein the first statistical result may be used to indicate whether the quality of the characteristic packet stream is deteriorating, i.e., whether switching needs to be performed.

[00138] Upon determining that the feature packet stream needs to be switched, the first device 10 may switch the feature packet stream to the second network channel.

[00139] Next, an example of the above-described channel switching method is described using FIG. 4. Fig. 4 is a flowchart of another embodiment of a channel switching method according to an embodiment of this application, including:

[00140] Step 401: Activating a network application in response to a user operation.

[00141] In particular, the user may perform an activation operation on the electronic device 100 to activate the network application. For example, a user may touch an icon for a network application on the electronic device 100. In response to the user's actions, the application layer 11 in the electronic device 100 activates the network application. It is understood that the above example only shows an example of a scenario in which a network application is activated by touch, which is not a limitation for this embodiment of this application. In some embodiments, the network application may also be activated by performing another operation (eg, double-tapping or sliding). The above network application may be a network application such as an online game, online video or online music.

[00142] FIG. 5a is a schematic diagram of a mobile phone desktop. As shown in FIG. 5a, the user can touch the video application icon on the desktop of the mobile phone to activate the video application. Therefore, a schematic diagram of a video display shown in FIG. 5b can be obtained.

[00143] Step 402: The environment detection component 121 detects that the network application is switching to the foreground or the network is changing and notifies the first policy management component 124.

[00144] In particular, the environment detection component 121 at the service layer 120 in the electronic device 100 can continuously detect the state of the above network application or the above network environment. Upon detecting that any network application comes to the foreground or the network environment changes, the environment detection component 121 may send a first notification message to the first policy management component 124, wherein the first notification message may be used to notify the first policy management component 124. that the network application is brought to the foreground or the network environment changes. It is understood that the above first notification message may further include a network application identifier (eg, the network application identifier may be a UID), and this identifier may be used to uniquely identify the network application.

[00145] For example, identifying a network application can be implemented using the following code:

[00146] Step 403: The first policy control component 124 receives the first notification message sent by the environment detection component 121 and determines whether the current network application satisfies the condition for enabling acceleration.

[00147] Specifically, after receiving the first notification message sent by the environment detection component 121, the first policy management component 124 may determine based on the first notification message that the network application has been switched to the foreground. The first policy management component 124 may then further determine whether the network application is included in the predefined application whitelist.

[00148] During a particular implementation, an application whitelist may be predefined in the first policy management component 124. The application whitelist may include a plurality of network applications, and each network application may be identified using the above identifier. An application whitelist can be used to represent network applications that can be accelerated. A network application in a preset application whitelist may include a service type. For example, a network application in a predefined application whitelist may be a sensitive service, and the sensitive service may include a latency-sensitive service, a packet loss ratio-sensitive service, etc. When the network application identifier in the first notification message is compared with the network application identifiers applications in the preset application white list, it can be determined whether the network application in the first notification message is included in the preset application white list. If the network application in the first notification message is included in the predefined application whitelist, it may be determined that the network application satisfies the acceleration activation condition; or if the network application in the first notification message is not included in the predefined application whitelist, it may be determined that the network application does not meet the acceleration activation condition.

[0014 9] For example, Table 1 is a whitelist of network applications.

[00150] It can be understood that if the current network application is not in the predefined application whitelist, that is, the service type of the current network application is an insensitive service, when detecting degradation of the primary network channel, the electronic device 100 may further detect another network channel with better quality. and then the insensitive service can be directly switched to a network link with better quality.

[00151] Step 404: The first policy control component 124 sends a channel enable message to the second path control component 131 to activate the network channel.

[00152] Specifically, if the first policy control component 124 determines that the current network application satisfies the acceleration enable condition, the first policy control component 124 may send a channel enable message to the second path control component 131, wherein the channel activation message is used to indicate the second control component 131 way to activate a network channel (eg, a primary network channel).

[00153] Step 405: The second path control component 131 requests the path of the primary network link from the first path control component 123.

[00154] Specifically, after receiving the channel enable message sent by the first policy control component 124, the second path control component 131 may send a primary network channel request to the first path control component 123, wherein the primary network channel request is used to request the path of the primary network channel. For example, the primary network channel may be the primary Wi-Fi channel.

[00155] Step 406: The first path management component 123 sends the path of the primary network link to the second path management component 131.

[00156] In particular, the first path management component 123 may pre-configure the paths of a plurality of network links. For example, the plurality of network channels may include a primary Wi-Fi channel, a secondary Wi-Fi channel, a primary cellular channel, and a secondary cellular channel. The primary Wi-Fi channel and secondary Wi-Fi channel can operate in the 2.4 GHz or 5 GHz band. For example, if the primary Wi-Fi channel operates in the 2.4 GHz band, the secondary Wi-Fi channel operates in the 5 GHz band; or if the primary Wi-Fi channel operates in the 5 GHz frequency range, the secondary Wi-Fi channel operates in the 2.4 GHz frequency range. In addition, the primary cellular channel and the secondary cellular channel may correspond to the operator's network. For example, the primary cellular link may use SIM 1 (SIM 1 belongs to Operator A's network) and the secondary cellular link may use SIM 2 (SIM 2 belongs to Operator A's network). operator B). Typically, the priority of the primary Wi-Fi channel is higher than the priorities of the other three channels. Therefore, the primary network channel is usually the primary Wi-Fi channel. It can be understood that the above-mentioned predefined channels are merely an example for description, which does not limit the embodiments of this application. In some embodiments, more channels may be included. Moreover, using the primary Wi-Fi channel as the primary network channel is only a preferred solution and is not a limitation to this embodiment of this application. In some embodiments, another network channel may also be selected as the primary network channel.

[00157] Upon receiving the primary network channel request sent by the second path control component 131, the first path control component 123 may select one network channel from a plurality of network channels as the primary network channel (for example, the primary network channel is the primary Wi-Fi channel) , and send the path of the primary network channel to the second path control component 131.

[00158] Step 407: The second path control component 131 stores the received path of the primary network link.

[00159] Specifically, after receiving the path of the primary network channel sent by the first path control component 123, the second path control component 131 may store the path of the primary network channel. For example, the primary network link path may be represented as "Wi-Fil".

[00160] FIG. 6 is a schematic representation of the effect of using a primary network channel by a mobile phone. As shown in FIG. 6, after the mobile phone receives the primary network channel path, the primary network channel can be used to watch video.

[00161] It is understood that the current network application (eg, the video application in FIG. 6) may include a plurality of streams (eg, a video stream and an audio stream), and the plurality of streams may be transmitted over the above primary network channel.

[00162] Step 408: The first policy management component 124 sends a traffic detection request to the traffic reading component 133.

[00163] In particular, a traffic sensing request may be used to direct traffic sensing component 133 to collect statistics on network application packets on a primary network channel. The traffic discovery request may include an identifier (eg, a UID) of the current network application to be discovered, which is used to request discovery of a network application flow corresponding to the UID on the primary network channel. It can be understood that the stream of the above network application may be in the form of a packet.

[00164] It should be noted that step 4 08 may be performed concurrently with step 404 or may be performed at any time after step 404. This is not particularly limited in this application.

[00165] Step 409: The traffic reading component 133 sends a traffic report request to the traffic reporting component 141.

[00166] Specifically, after receiving a traffic detection request sent by the first policy management component 124, the traffic reading component 133 may send a traffic reporting request to the traffic reporting component 141, wherein the traffic reporting request may be used to indicate the reporting component 141 about traffic to detect network application packets on the current primary network link and report the detected packets. It will be understood that the above traffic detection request may include an identifier (eg, UID) of the network application.

[00167] Step 410: Traffic reporting component 141 performs traffic detection and reports detected packets to traffic reading component 133.

[00168] Specifically, upon receiving a traffic report request sent by the traffic reading component 133, the traffic reporting component 141 may detect, based on the network application identifier (e.g., UID) in the traffic report request, network application packets corresponding to network application identifier to receive network application packets on the primary network channel, and may report detected network application packets to traffic reading component 133.

[00169] During a particular implementation, traffic reporting component 141 may invoke a component (eg, an Android system Netfilter component) to receive network application packets over the primary network channel. It is understood that the above Netfilter component is merely an example for description, which does not limit the embodiments of this application. In some embodiments, the packet detection described above may also be completed using another component.

[00170] For example, the above network channel parameters can be implemented using the following code:

[00171] It is understood that the detected packets may be packets in one or more feature flows in the current network application, and the feature flow may be the flow with the highest sensitivity in the network application, that is, a flow that has a relatively large impact in the current network application. In addition, the amount of the network channel can be estimated using the above network channel parameters.

[00172] Step 411: Environment detection component 121 detects a scenario in which electronic device 100 is located.

[00173] In particular, the scenario may be a scenario in which the user is located, that is, a scenario in which the electronic device 100 is located. For example, the scenario may be that the user is in an elevator. It can be understood that the elevator scenario is merely an example for description, and the scenario may further include another scenario causing a network change, such as a scenario such as a high-speed railway or a parking garage. Now the elevator scenario is used as an example for the description. When a user enters an elevator, the elevator rises or falls, which may cause the user's gravity to change. For example, when an elevator rises, there is added weight; or when the elevator goes down, weightlessness occurs. Therefore, the acceleration sensor in the electronic device 100 can be used to detect added weight and weightlessness. When the acceleration sensor detects that the user is in a state of weightlessness or added weight, that is, the acceleration of the electronic device 100 in the vertical direction is detected, it can be determined that the user is in an elevator environment. In this case, if the environment detection component 121 detects that the user is in the elevator, the environment detection component 121 may send a scenario change notification message to the first policy management component 124, and the scenario change notification message is used to notify the first policy management component 124. that the scenario the user is in changes (eg, the user enters an elevator), so that the first policy management component 124 can initiate discovery of a secondary network channel.

[00174] In addition, when the elevator ascends or descends, the elevator may stop according to the needs of different users (for example, different users may press different floors). Therefore, the elevator can continue to move or stop in the vertical direction. Since the electronic device 100 does not detect movement in the horizontal direction when the elevator is ascending or descending, it can still be determined that the electronic device 100 is in the elevator, and the movement in the horizontal direction can be detected by an acceleration sensor in the electronic device 100. For example, if acceleration in the horizontal direction is detected by the above acceleration sensor, movement in the horizontal direction can be detected.

[00175] When the electronic device 100 detects that the electronic device 100 has acceleration in the horizontal direction, that is, when the electronic device 100 moves horizontally, it can be determined that the user has exited the elevator, that is, the electronic device 100 exits the elevator. In this case, detection of the secondary network channel may not be performed in advance, and therefore the scenario change notification message does not need to be sent to the first policy control component 124, thereby saving power consumption of the electronic device 100 caused by detection of the secondary network channel.

[00176] Optionally, the electronic device 100 may also determine, by detecting the mobile network signal strength, whether the user's scenario is changing. For example, when the mobile network signal strength is weak, it can be determined that the user is entering a relatively poor network environment. In this case, the electronic device 100 may determine that the script has changed and may send a script change notification message to the first policy management component 124 to detect the secondary network channel in advance. When the signal strength of the mobile network becomes higher, it can be determined that the user has entered a relatively good network environment. In this case, detection of the secondary network channel may not be performed in advance, and the scenario change notification message may not be sent to the first policy control component 124, thereby reducing the power consumption of the electronic device 100 caused by detection of the secondary network channel.

[00177] Step 412: The environment detection component 121 sends a script change notification message to the first policy management component 124.

[00178] Specifically, upon detecting a script change, the environment detection component 121 may send a script change notification message to the first policy management component 124 .

[00179] Step 413: The first policy control component 124 forwards a script change notification message indicating the script change to the second path control component 131.

[00180] Step 414: The second path control component 131 requests a secondary network channel from the first path control component 123.

[00181] In particular, since the signal in the elevator is generally poor, if channel selection and switching are performed after the user enters the elevator, a relatively large service delay may occur, which may cause the user's experience to deteriorate. Therefore, when it is detected that a user enters the elevator, a secondary network channel can be preselected. Therefore, channel switching can be accelerated, and service delay caused by channel switching can be reduced.

[00182] Upon receiving the script change notification message sent by the first policy control component 124, the second route control component 131 may send a secondary network channel request to the first path control component 123, wherein the secondary network channel request may be used to request the secondary network channel.

[00183] Optionally, the above secondary network channel request may further carry a label, and the label may be used to indicate that a switch of the primary network channel is predicted rather than actually performed.

[00184] With reference to FIG. 7a according to Fig. 7c, secondary network channel selection is described next using a mobile phone as an example. As shown in Fig. 7a, the mobile phone has four network channels: a primary Wi-Fi channel (for example, Wi-Fi), a secondary Wi-Fi channel (for example, Wi-Fi2), a primary cellular channel (for example, Mobile1) and a secondary cellular channel (for example, Mobile2). It is assumed that the mobile phone is currently running a network application (for example, WeChat) on the Wi-Fil channel (the primary network channel), and the network application includes stream A (for example, a video stream) and stream B (for example, an audio stream). Upon receipt of the scenario change notification, the mobile phone may preselect a secondary network channel, where the secondary network channel may be one of the above-mentioned secondary Wi-Fi channels (eg, Wi-Fi2), primary cellular channels (eg, Mobile1), and secondary cellular channel ( e.g. Mobile2) with optimal quality. Once from the above secondary Wi-Fi channel (for example, Wi-Fi2), primary cellular channel (for example, Mobile1) and secondary cellular channel (for example, Mobile2), one is selected as the secondary network channel (for example, Mobile1) , the channel path of Mobile1 can be saved.

[00185] When the mobile phone detects through further packet detection that the quality of stream A does not meet the requirement, in this case, only stream A can be switched to the secondary network channel, that is, to the Mobile1 channel. As shown in FIG. 7b, in this case, the above-mentioned stream B may still be transmitted on the primary network channel, that is, the Wi-Fi channel, and stream A may be transmitted on the secondary network channel, that is, the Mobile1 channel.

[00186] It should be noted that the above example is simply an example of a scenario in which one stream is switched, which does not limit the embodiments of this application. In some embodiments, a scenario in which multiple threads are switched may also be included.

[00187] Optionally, when the mobile phone detects through further packet detection that the quality of stream A does not meet the requirement, in this case, both stream A and stream B may be switched to the secondary network channel, that is, the Mobile1 channel. As shown in FIG. 7C, in this case, both stream A and stream B are transmitted on the Mobile1 channel, and the Wi-Fil channel is disabled.

[00188] Next, with reference to FIG. 8a and fig. 8b describes a channel switch initiation condition using a mobile phone as an example. In fig. Figure 8a shows the process of initiating channel switching of non-sensitive services. As shown in FIG. 8a, the traffic sensing component 133 in the mobile phone receives, for a predetermined first duration, heartbeat packets detected by the traffic reporting component 141, and can determine, through statistical analysis of the heartbeat packets for a predetermined first duration, whether the quality of a network channel is deteriorating. . Since the current service is an insensitive service, the above-mentioned preset first duration can be set to a relatively long time, for example, 5 seconds. After determining that the quality of the current network channel is deteriorating, the traffic sensing component 133 may send a switch notification to the second policy control component 132 to initiate switching of the network channel. For example, the quality of other network links can be assessed and the current insensitive service can be switched to another network link with optimal quality.

[00189] FIG. 8b is a process for initiating channel switching of a sensitive service. As shown in FIG. 8b, after receiving the scenario change notification message sent by the first policy control component 124, the second path control component 131 in the mobile phone can determine that the scenario has changed. In this case, the second path control component 131 can request the secondary network channel, so that when the quality of the network application characteristic stream deteriorates, the second path control component 131 can timely switch to the secondary network channel, so as to save switching time and improve user experience. Then, the traffic reading component 133 in the mobile phone receives, for a predetermined second duration, the pilot flow packets detected by the traffic reporting component 141, and can determine the service quality of the characteristic flow in the current network application by statistically analyzing the pilot flow packets for the predetermined second duration. duration. The predetermined second duration may be equal to the predetermined first duration, such as 5 seconds, or may be shorter than the predetermined first duration, such as 3 seconds. When it is determined that the quality of service of the characteristic flow has deteriorated, a switch notification may be sent to the second policy control component 132 to initiate switching of the network channel. For example, the characteristic stream of the current network application may be switched to a secondary network channel.

[00190] Step 415: The first path control component 123 receives the secondary network channel request and requests the activation status of each secondary network channel.

[00191] Specifically, upon receiving a secondary network channel request sent by the second path control component 131, the first path control component 123 may send a channel status request to the network discovery component 122, wherein the channel status request may be used to request the activation status of each additional network channel. It is understood that the above-mentioned activation status may include an available state and an unavailable state. The available state can be used to represent that the optional network channel can be activated, and the unavailable state can be used to represent that the optional network channel is disabled. The secondary network channel may include a secondary Wi-Fi channel, a primary cellular channel, a secondary cellular channel, and the like.

[00192] Step 416: The network discovery component 122 detects the activation status of each additional network channel and sends the activation status of each additional network channel to the first path control component 123.

[00193] In particular, after receiving the channel status request sent by the first path control component 123, the network discovery component 122 can detect the activation status of each additional network channel. During a particular implementation, network discovery component 122 may be configured to control the switching of each additional network channel. When any additional network channel is activated, the additional network channel is in an available state; and when any additional network channel is disabled, the additional network channel is in an unavailable state. Therefore, after detecting the activation status of each additional network channel requested by the first path control component 123, the network discovery component 122 may send the activation status of each additional network channel to the first path control component 123.

[00194] Step 417: The first path control component 123 queries the quality of each available network channel.

[00195] Specifically, upon receiving the activation status of each additional network channel, the first path control component 123 may select an available network channel (ie, the additional network channel in an available state) and may further send a channel evaluation request to the channel and application quality evaluation component 125, wherein a channel estimation request may be used to request an estimate of the quality of an available network channel.

[00196] Step 418: The link and application quality evaluation component 125 evaluates the quality of each available network channel and sends the evaluation result to the first path control component 123.

[00197] Specifically, after receiving the channel evaluation request sent by the first path control component 123, the channel and application quality evaluation component 125 can evaluate the quality of each available network channel in accordance with the channel evaluation request. For example, link quality may include latency, packet loss rate, bandwidth, speed, etc. of the link. The above estimate may be an estimate of the Round-Trip Time (RTT) of an available network channel, and the network channel with the minimum round-trip time is optimal. Optionally, when there is a selection history record for an available network channel, that is, the above-mentioned available network channel has been selected as a network channel, in which case the quality of the channel can be estimated based on the above-mentioned RTT and the historical record, wherein the historical record may include a historical coefficient reception, the number of historical moments when the quality of the channel was poor, etc. This embodiment of this application does not impose particular restrictions on the channel quality estimation method. After completing the quality evaluation on all available network channels in the channel evaluation request, the channel and application quality evaluation component 125 may send the above evaluation result to the first path control component 123 .

[00198] Step 419: The first path control component 123 determines a secondary network channel based on the estimation result and sends the path of the secondary network channel to the second path control component 131.

[00199] Specifically, after receiving the evaluation result, the first path control component 123 may select an optimal available network channel as a secondary network channel based on the evaluation result, and may send the path of the secondary network channel to the first path control component 123.

[00200] Step 420: The second path control component 131 receives and stores the path of the secondary network channel that is sent by the first path control component 123.

[00201] Specifically, after receiving the secondary network channel path sent by the first path control component 123, the second path control component 131 may previously store the secondary network channel path. It is clear that at step 411 only a scenario change is detected, that is, the current network may cause the service to stop, but the switching condition is not satisfied. In this case, the electronic device 100 does not switch to the secondary network channel, that is, the electronic device 100 still uses the primary network channel.

[00202] For example, after receiving at time t1 the path of the secondary network channel sent by the first path control component 123, the second path control component 131 may previously store the path of the secondary network channel. In this case, the electronic device 100 does not switch to the secondary network channel, that is, the electronic device 100 still uses the primary network channel. Then, when the quality of the characteristic flow of the current network application is detected to deteriorate at time t2, the switching condition is achieved. In this case, the electronic device 100 may switch the feature stream from the primary network channel to the secondary network channel.

[00203] Step 421: The traffic reporting component 141 provides the traffic report to the traffic reading component 133.

[00204] In particular, the traffic reporting component 141 may continuously detect packets of the current primary network channel and provide a report of the detected packets to the traffic reading component 133.

[00205] Step 422: The traffic reading component 133 receives the packets reported by the traffic reporting component 141, parses the packets to obtain a packet analysis result, and sends the packet analysis result to the second policy management component 132.

[00206] In particular, the packets may be packets of each network application flow on the primary network channel. After receiving the packets, the traffic reading component 133 may analyze the packets. Packet analysis may be based on packet characteristics to identify a characteristic flow, where the characteristic flow may be the flow with the highest sensitivity in the network application. For example, Game For Peace is used as an example. The characteristic flow of the game can be the voice flow, that is, the voice flow has a relatively large impact on the game and has the greatest sensitivity. When the quality of the voice stream is poor (such as latency and packet loss ratio are not up to standard), it will seriously affect the user's gaming experience. Therefore, the voice stream needs to be identified, and the packetized voice stream packets need to be further collected and analyzed. Therefore, the packet analysis result can be obtained. The result of the packet analysis can be used to indicate whether the characteristic flow meets a service requirement, for example, whether a delay requirement is satisfied or whether a packet loss ratio requirement is satisfied. The result of the packet analysis may be sent to the second policy control component 132.

[00207] Voice stream packet recognition can be implemented by collecting statistics on pilot packets. For example, using UDP as an example, the characteristics of voice data stream packets can be represented using the following characteristics:

Uplink: udp.payload[6]=0×64;

Downlink: udp.payload[6]=0×65.

[00208] FIG. 9 is a schematic representation of voice stream pilot packets in the UDP protocol.

[00209] That is, a predefined field in the payload in the above-mentioned uplink and downlink packets is read to identify whether the packets are voice stream packets.

[00210] Statistics of the voice stream packets can then be collected and hence the latency and/or packet loss rate for the voice stream packets can be obtained. During a particular implementation, packet statistics of the voice stream may be collected for a predefined duration (eg, 5 s). For example, if the latency and/or packet loss ratio for the voice stream packets do not meet the requirement, it may be determined that the quality of the voice stream is poor. In this case, a switchover may be initiated to switch the voice stream to a secondary network channel. It should be noted that in the above example, only the game is used as an example for description. A particular application may additionally include another network application. For example, for Baidu Network Disk, the characteristic flow of a network application is the download flow, that is, the download flow packet may be in the previous packets, and the factor influencing the download flow packet may be a coefficient. In addition, the network application may further include a social network application such as WeChat. The characteristic stream of a network application is the video stream, that is, the video stream packet may be in previous packets, and the factor affecting the video stream packet may be latency/or packet loss rate.

[00211] It is understood that in addition to the above voice stream, the feature stream may further include a game stream. Using Game For Peace as an example, the number of UDP packets can be periodically counted to determine whether the current packet stream is a combat stream. Currently, Game For Peace UDP packets are counted at 500ms intervals. Therefore, the total number of packets in a period can be counted to determine whether a packet is a combat flow. For example, if the total number of packets over a 500 ms period is greater than 10, the packet flow is a combat flow. Fig. 10 is a schematic representation of packet statistics of a battle stream in the UDP protocol. As shown in FIG. 10, the horizontal axis indicates time, and the vertical axis indicates the total number of packets. Since almost 30 packets are stored per second, it is possible to calculate 15 packets in 500 ms. Therefore, it can be determined that the packet stream is a combat stream.

[00212] The following uses Honor of Kings as an example. For Honor of Kings, the UDP protocol number and packet header characteristic "payload=0x00010000" are used to filter combat packets. Fig. 11 is a schematic diagram of battle flow pilot packets in the UDP protocol.

[00213] Step 423: The second policy control component 132 determines switching based on the result of the packet analysis and requests to obtain the secondary network link path.

[00214] Specifically, after receiving the packet analysis result provided by the traffic reading component 133, the second policy control component 132 can determine, based on the packet analysis result, whether to perform channel switching. During a particular implementation, if the characteristic stream of the current network application (for example, a voice stream in a game, a video stream in WeChat, or a Baidu Network Disk download stream) does not meet a requirement (for example, latency and/or packet loss ratio), it can be determined that it is necessary switch channels. In this case, the second policy control component 132 may send a request to obtain the secondary network link path to the second path control component 131 to obtain the secondary network link path. For example, if the secondary network link is a primary cell, the path of the secondary network link may be, for example, Mobile1.

[00215] For example, a secondary network link path request could be implemented using the following code:

[00216] Additionally, in a particular implementation, the path of the network link (eg, the path may be represented by the device number of the network adapter or SIM card) may be defined in the data structure. The code example looks like this:

[00217] As shown in the above code, sk_bound_dev_if is the device number of the target network card or target SIM card to switch. It is understood that the packet can be received using the aforementioned network adapter or SIM card. For the code to get the package, see the following example:

[00218] It is understood that if it is determined through packet analysis that the characteristic flow of the current network application meets the requirement, that is, switching is not required, in which case the first device 10 may remove the secondary network channel path to free up resource and reduce power consumption of the first device 10 Optionally, the first device 10 may delete the secondary network channel path after a predetermined duration (eg, a predetermined third duration) has elapsed. Thus, it can be ensured that if the quality of the characteristic stream deteriorates during the predetermined third duration, the first device 10 can switch to the secondary network channel in a timely manner to avoid that switching cannot be performed because the secondary network channel path is removed .

[00219] It should be noted that since the electronic device 100 may be located in different environments, wireless networks are quite different. For example, when the electronic device 100 detects that the network environment in which the electronic device 100 is currently located is relatively poor, the secondary network may be activated. Then, when the electronic device 100 detects that the current service meets the service requirement, switching is not required (eg, the electronic device 100 enters a relatively good network environment), the electronic device 100 can continue to use the current network and does not switch to the secondary network. Therefore, the electronic device 100 may only perform secondary network discovery, for example, perform steps 415 through steps 420 to complete secondary network discovery. In addition, after detection of the secondary network is complete, the electronic device 100 may further activate the secondary network. The activation operation can speed up the switching procedure, thereby reducing the switching delay. That is, when detecting a current environment (eg, an elevator scenario) in which the electronic device 100 is located, the electronic device 100 may perform only secondary network detection or may detect the secondary network and activate the secondary network. However, switching is not actually performed during the secondary network discovery phase and during secondary network activation. Upon detecting that the current service cannot satisfy a service requirement, the electronic device 100 may switch the current service (eg, one or more streams of the current service) to the activated secondary network.

[00220] Step 424: The second policy control component 132 sends the path of the secondary network link to the second path control component 131.

[00221] Step 425: The second policy control component 132 sends a channel switch indication to the policy execution component 142.

[00222] Specifically, after receiving the secondary network channel path sent by the second path control component 131, the second policy control component 132 may send a channel switching indication to the policy execution component 142, wherein the channel switching indication may be used to instruct the policy execution component 142 switch the above characteristic stream from the current primary network channel to the secondary network channel so that channel switching is performed faster, thereby reducing the delay caused by channel switching and improving the user experience.

[00223] Step 426: Policy execution component 142 performs channel switching.

[00224] Specifically, after receiving the channel switch indication sent by the second policy control component 132, the policy execution component 142 may switch the above characteristic flow from the current primary network channel to the secondary network channel. That is, another stream of the above network application can still be transmitted on the primary network channel, and the above characteristic stream can be transmitted on the secondary network channel, so that switching can be performed quickly, thereby ensuring quality of service and user convenience.

[00225] Optionally, the entire network application may be switched to the secondary network channel, that is, the primary network channel may be disabled and all network application flows are transferred to operate on the secondary network channel.

[00226] FIG. 12 is a schematic diagram of the use of a secondary network channel by a mobile phone. As shown in FIG. 12, after the mobile phone receives the channel switching instruction, the mobile phone can switch the video stream from the current primary network channel to the secondary network channel, and can use the secondary network channel to watch the video to avoid video freezing.
