2) And (3) policy management: a flow switching process and/or flow binding is performed.

For convenience of understanding, the following embodiments of the present application take the terminal device 100 with the structure shown in fig. 1 and fig. 2 as an example, and specifically describe the data downloading method provided in the embodiments of the present application with reference to the drawings and application scenarios.

Fig. 3 is a flowchart of a data downloading method according to an embodiment of the present application, and as shown in fig. 3, the data downloading method may include:

step 301, a system environment sensing module of the service layer detects a download request. Specifically, after a user triggers data download on an operation interface of an Application (APP), a system environment sensing module may detect a download request from the APP.

For example, the user may trigger data downloading on the operation interface of the APP by: a user clicks an installation icon corresponding to an APP to be downloaded on an operation interface of the APP to be downloaded; or, the user clicks a download icon corresponding to the video to be downloaded in the video playing APP.

Step 302, the system environment sensing module notifies the policy management module of the service layer to switch the APP to the foreground for operation.

In step 303, the policy management module determines whether the WiFi network switch and the cellular network switch of the terminal device 100 are in an on state.

In step 304, after determining that both the WiFi network switch and the cellular network switch of the terminal device 100 are in the on state, the policy management module sends an enabling notification to the path management module of the process defense layer to notify the path management module of the process defense layer to request all network paths in the WiFi network and the cellular network.

Wherein all network paths in the WiFi network and the cellular network include: a first network path, a second network path, and a third network path; wherein the first network path comprises a network path between the first WiFi network interface and the network side, the second network path comprises a network path between the second WiFi network interface and the network side, and the third network path comprises a network path between the cellular network interface and the network side.

Step 305, the path management module of the process gatekeeper layer requests all network paths in the WiFi network and the cellular network from the path management module of the service layer.

Step 306, the path management module of the service layer probes all network paths in the WiFi network and the cellular network to obtain available network paths, and notifies the available network paths to the path management module of the Cheng Shou protection layer.

Step 307, the policy management module of the service layer sends a start notification to the traffic sensing module of the process guarding layer to notify the traffic sensing module of the process guarding layer to sense traffic.

And 308, the flow sensing module of the process guard layer issues the sensing module to the kernel layer, wherein the sensing module comprises parameters such as a reporting period of flow, the size of a data packet and/or the value of an internal field (for example, a content type field) of the data packet, and the like, and is used for indicating the kernel layer to report the flow to the flow sensing module according to the reporting period in the sensing model after detecting the data stream conforming to the parameters in the sensing model.

309, reporting the detected data streams which conform to the parameters in the sensing model to a flow sensing module by the kernel layer, and acquiring the data streams of the downloading types and the number of the data streams of the downloading types from the flow reported by the kernel layer after the flow sensing module acquires the flow reported by the kernel layer; and the flow sensing module reports the data stream of the download type and the quantity in the data of the download type to a strategy management module of the process defense layer.

At step 310, the policy management module of the process daemon notifies the kernel of the initial flow binding policy. The initial flow binding policy may be to distribute the data flow of the download type to the first network path, the second network path, and the third network path in an average distribution manner.

In step 311, the kernel layer executes an initial flow binding policy, and downloads the data flow through the first network path, the second network path, and the third network path.

In step 312, after the data stream starts to be downloaded, the traffic sensing module of the process defense layer detects the download rates of the first network path, the second network path, and the third network path within a predetermined time period, and transmits the download rates obtained by the detection to the policy management module of the process defense layer.

The predetermined time period may be set according to system performance and/or implementation requirements during specific implementation, and the length of the predetermined time period is not limited in this embodiment, for example, the predetermined time period may be 1 second.

Step 313, the policy management module of the process defense layer determines the flow distribution ratio among the first network path, the second network path and the third network path according to the download rate, and determines the flow binding policy according to the flow distribution ratio.

The flow binding policy may be to allocate the data flow to a first network path, a second network path, and a third network path according to the number of the data flow sides and a flow allocation ratio.

In step 314, the policy management module of the process daemon layer notifies the flow binding policy to the kernel layer.

Step 315, the kernel layer executes a flow binding policy, and downloads the data flow through the first network path, the second network path, and the third network path.

Step 316, in the process of downloading the data stream, a traffic sensing module of the process guardian detects quality of experience (QOE) of the data stream carried on the first network path, the second network path, and the third network path; if a first data flow is detected that has a QOE below a predetermined QOE threshold, a policy management module of the feed Cheng Shou sheath is notified of the event that the first data flow is detected.

The predetermined QOE threshold may be set according to system performance and/or implementation requirements, and the size of the predetermined QOE threshold is not limited in this embodiment.

Step 317, the policy management module of the process daemon layer notifies the flow switching policy to the kernel layer. Wherein the flow switching policy includes switching the first data flow to a target network path; the target network path is one of other network paths, the other network paths include network paths other than an original network path among a first network path, a second network path and a third network path, and the original network path is a network path originally carrying a first data stream.

In step 318, the kernel layer executes a flow switching policy to switch the first data flow to the target network path.

The following describes a method for selecting a target network path with reference to fig. 4. Fig. 4 is a flowchart of a method for selecting a target network path according to an embodiment of the present application, and as shown in fig. 4, the method may include:

step 401, sorting the other network paths according to the number of data streams currently carried by the other network paths.

Step 402, determine whether there is a network path with the least bearer data flow in the other network paths. If so, go to step 403; if there are at least two network paths carrying the least data flows among the other network paths, step 404 is executed.

Step 403, selecting the network path bearing the least data flow as the target network path.

Step 404, when there are at least two network paths with the least bearer data flows in other network paths, determining whether the at least two network paths include one or a combination of a first network path and a second network path, and at least one network path in a third network path; namely, whether a WiFi network path and a cellular network path exist in the at least two network paths at the same time is judged.

If so, go to step 405; if the at least two network paths only include the first network path and the second network path, or the at least two network paths only include at least two network paths of the third network path, step 408 is performed.

Step 405, judging whether the traffic package of the cellular network used by the terminal equipment is an unlimited package; if not, go to step 406; if the flow package is an unlimited package, step 407 is performed.

At step 406, one of the first network path and the second network path is selected as a target network path.

Step 407, select one of the third network paths as the target network path.

Step 408, randomly selecting one network path from the at least two network paths as a target network path.

In the following description, it may be considered that the WiFi path 0 belongs to the first network path, the WiFi path 1 belongs to the second network path, and the cellular path 0 and the cellular path 1 belong to the third network path.

1. The first condition is as follows: the first data flow carried in WiFi path 0 is detected to have QOE lower than the predetermined quality of experience threshold and needs to be handed over to the target network path.

The number of data flows carried on other network paths is as follows:

WiFi path 1:5;

cellular path 0:4;

cellular path 1:3.

the number of data flows carried on cellular path 1 is the smallest and therefore cellular path 1 is selected as the target network path.

2. Case two: the first data flow carried in WiFi path 0 is detected to have QOE lower than the predetermined quality of experience threshold and needs to be handed over to the target network path.

The number of data flows carried on other network paths is as follows:

WiFi path 1:3;

cellular path 0:3; the flow package is an unlimited package;

cellular path 1:5.

since the number of data streams carried on WiFi path 1 and cellular path 0 is equal and minimal, and the traffic package corresponding to cellular path 0 is an unlimited package, cellular path 0 is selected as the target network path.

3. Case three: when the first data flow carried in the WiFi path 0 is detected to have a QOE lower than a predetermined quality of experience threshold, it is necessary to switch to the target network path.

The number of data flows carried on other network paths is as follows:

WiFi path 1:3;

cellular path 0:3; the flow package is not an unlimited package;

cellular path 1:5.

since the number of data streams carried on WiFi path 1 and cellular path 0 is equal and minimum, and the traffic package corresponding to cellular path 0 is not an unlimited package, wiFi path 1 is selected as the target network path.

Next, a method for detecting the QOE of the data streams carried on the first network path, the second network path, and the third network path by the traffic sensing module of the process defense layer in step 316 is described.

In this embodiment, the QOE of the data stream may be detected by using a download rate threshold + window. In specific implementation, the duration of the window may be preset, and the duration of the window may be set according to a requirement, for example, the duration of the window may be set to be the length of 4 slots (slots), and the duration of each slot is 500 milliseconds.

Then, the download rate of the data stream is detected in each slot, if the download rate of the data stream in one slot is lower than a predetermined rate threshold, the slot is determined to be Bad, and if at least N slots of 4 consecutive slots are Bad, the QOE of the data stream can be determined to be lower than a predetermined QOE threshold. The predetermined rate threshold may be set according to system performance and/or implementation requirements during specific implementation, and the size of the predetermined rate threshold is not limited in this embodiment, for example, the predetermined rate threshold may be 5000bps; n is a positive integer less than or equal to 4, and specific values are not limited, for example, N may be 3. Table 1 below gives a specific example of detecting the QOE of a data flow.

TABLE 1

slot	1	2	3	4	5	6	7
								Download Rate (bps)	8000	8000	3000	2000	1000	1000	1000
slot QOE	good	good	bad	bad	bad	bad	bad
								QOE of data streams				good	bad	bad	bad

In table 1, a QOE of a data flow of good means that the QOE of the data flow is not lower than the predetermined QOE threshold, and a QOE of a data flow of bad means that the QOE of the data flow is lower than the predetermined QOE threshold.

In addition, in this embodiment of the application, after the kernel layer downloads the data stream, the traffic sensing module of the process daemon layer may further detect the QOE of the data streams carried on the first network path, the second network path, and the third network path; if the network path to be switched exists in the first network path, the second network path and the third network path, the flow sensing module informs the event of the network path to be switched to a policy management module of a protective layer of the Cheng Shou, and the policy management module informs the flow switching policy to a kernel layer. The stream switching policy here may be to switch the data stream carried on the network path to be switched to a target network path, or to allocate the data stream to other network paths according to a stream allocation ratio. Then, the inner core layer executes the stream switching strategy, and switches the data stream carried on the network path to be switched to the target network path, or distributes the data stream to other network paths according to the stream distribution proportion.

The network path to be switched is a network path among a first network path, a second network path and a third network path, and the number of data streams of which the QOE is lower than a preset QOE threshold value in the data streams carried by the network path to be switched is greater than a preset number threshold value; the target network path is one of other network paths; the other network paths include network paths other than the network path to be switched among the first network path, the second network path and the third network path.

The predetermined number threshold may be set according to system performance and/or implementation requirements when the specific implementation is performed, and the size of the predetermined number threshold is not limited in this embodiment, for example, the predetermined number threshold may be 25% of the total number of data streams carried on the network path to be switched.

The stream allocation ratio mentioned here can also be determined according to the download rate of other network paths, and is not described herein again.
