Description

Data stream scheduling method, terminal and storage medium

Technical Field

The present application relates to the field of mobile communication networks, and in particular, to a data stream scheduling method, a terminal, and a storage medium.

Background

The fifth Generation Mobile Communication Technology (5 th Generation Mobile Communication Technology, abbreviated as 5G) is a new Generation broadband Mobile Communication Technology with the characteristics of high speed, low time delay and large connection, and is a network infrastructure for realizing man-machine interconnection. Currently, the 5G Communication network brings three major core application scenarios to us, namely Enhanced Mobile broadband (eMBB), Ultra-high-reliable and Low-Latency Communication (urrllc), and Massive machine type Communication (mtc).

In order to meet the application scenario of 5G communication network diversification, a 5G network access terminal (CPE) and a 5G network slice are derived. A technician or a user manually configures, in the 5G CPE, correspondence between data streams of different services and network slices of the three application scenarios, for example, specifies, according to a destination Internet Protocol Address (IP) or an Address field of the data stream, through which the data stream is transmitted. Although this way can realize that different types of services can be scheduled to different network slices, because the correspondence relationship needs manual configuration, the data stream of the service with the correspondence relationship configured manually can only be scheduled according to the manually configured correspondence relationship in the use process, and the data stream of the service without the correspondence relationship configured manually can only be scheduled to a matching network slice in the use process, which may cause the data stream to be scheduled to an unsuitable network slice, for example, the data stream that needs to be scheduled to a network slice for processing the eMBB type service is scheduled to a network slice for processing the mtc type service.

Therefore, it is desirable to provide a data flow scheduling scheme to better adapt to diversified application scenarios of a 5G communication network, so that the data flow scheduling is more flexible and accurate.

Disclosure of Invention

In order to solve the technical problems, the present application provides a data stream scheduling method, a terminal and a storage medium, which aim to implement intelligent scheduling of data streams of different types of services to different network slices, so as to fully utilize a 5G communication network and complete communication requirements of user diversified data streams.

In a first aspect, the present application provides a data flow scheduling method, which is applied to a 5G network access terminal. The data flow scheduling method comprises the following steps: receiving a data stream, wherein the data stream comes from electronic equipment, and the electronic equipment is accessed into a 5G wireless network through a 5G network access terminal; carrying out service identification on the data stream, and determining service type identification codes of services corresponding to the data stream, wherein different services correspond to different service type identification codes; determining a target 5G network slice matched with the data stream according to the mapping relation between the service type identification code and the 5G network slice, wherein different service type identification codes correspond to different 5G network slices; the data stream is scheduled to a network interface corresponding to the target 5G network slice.

Therefore, according to the data stream scheduling method provided by the application, the electronic equipment is accessed into the 5G wireless network through the 5G network access terminal, so that the electronic equipment can work in the 5G wireless network, and the service processing speed is faster.

In addition, in a 5G application scenario, after a data stream generated in a using process of the electronic device reaches the 5G network access terminal, the 5G network access terminal performs service identification on the data stream, and further determines a service type identification code corresponding to the data stream and a 5G network slice corresponding to the determined service type identification code, so that the data stream of services of different service types can be intelligently scheduled to a proper 5G network slice, and the purpose of fully utilizing a 5G communication network and completing communication requirements of diversified data streams of a user is achieved.

According to the first aspect, before scheduling the data flow to the network interface corresponding to the target 5G network slice, the method further comprises: judging whether the quintuple information corresponding to the data stream establishes a mapping relation with a network interface corresponding to the target 5G network slice; when the quintuple information establishes a mapping relation with a network interface corresponding to the target 5G network slice, executing a step of scheduling the data stream to the network interface corresponding to the target 5G network slice according to the mapping relation; and when the mapping relation between the quintuple information and the network interface corresponding to the target 5G network slice is not established, scheduling the data stream to the network interface corresponding to the default 5G network slice.

Therefore, the data stream scheduling method provided by the application schedules the data stream for which the service identification processing is performed to the network interface corresponding to the target 5G network slice directly based on the existing mapping relation when the quintuple information sets the scheduling mark for the quintuple information and the mapping relation is established between the quintuple information and the network interface corresponding to the target 5G network slice, so that the data stream comprising the quintuple information is scheduled to the specified network interface, and when the quintuple information does not establish the mapping relation with the network interface corresponding to the target 5G network slice, the data stream is subjected to the service identification processing, and simultaneously the data stream for which the service identification processing is performed is scheduled to the network interface corresponding to the default 5G network slice first, when the next wheel identifies the data stream, according to the identification result of the previous wheel or wheels, the data stream comprising the same quintuple information is directly dispatched to a specified network interface, so that the data stream can be dispatched to a proper network interface as far as possible under the condition of not influencing the data stream dispatching, and the service processing is carried out by a 5G network slice suitable for the data stream.

According to the first aspect, or any implementation manner of the first aspect above, before scheduling the data stream to a network interface corresponding to a default 5G network slice, the method further includes: clearing connection tracking information of the data stream; and establishing a mapping relation between the quintuple information and the network interfaces corresponding to the target 5G network slice.

Therefore, according to the data stream scheduling method provided by the application, the connection tracking information of the data stream of the determined target 5G network slice is cleared, and then the mapping relation between the quintuple information and the network interface corresponding to the target 5G network slice is established, so that the data stream including the same quintuple information received subsequently can not be scheduled to the network interface corresponding to the default 5G network slice according to the address recorded in the connection tracking information, but the data stream including the same quintuple information is directly scheduled to the specified network interface.

According to the first aspect, or any implementation manner of the first aspect above, the method further includes: and when the application providing the data stream cannot be determined after the service identification is carried out on the data stream, scheduling the data stream to a network interface corresponding to the default 5G network slice.

Therefore, the data stream scheduling method provided by the application directly schedules the data stream which cannot determine the target 5G network slice to the network interface corresponding to the default 5G network slice, so that the received data stream can be normally scheduled to the 5G wireless network.

According to the first aspect, or any implementation manner of the first aspect, before performing service identification on a data stream and determining a service type identifier of a service corresponding to the data stream, the method further includes: judging whether the quintuple information corresponding to the data stream establishes a mapping relation with a network interface corresponding to the target 5G network slice or not; when the quintuple information establishes a mapping relation with a network interface corresponding to the target 5G network slice, executing a step of scheduling the data stream to the network interface corresponding to the target 5G network slice according to the mapping relation; and when the mapping relation between the quintuple information and the network interface corresponding to the target 5G network slice is not established, performing service identification on the data stream, and determining a service type identification code of the service corresponding to the data stream.

Therefore, according to the data stream scheduling method provided by the application, since the data stream which is scheduled to the specific network interface is provided with the scheduling label, namely, the mapping relation between the quintuple information and the target 5G network slice is established, whether the mapping relation exists or not is judged before the data stream is received to perform service identification on the data stream, and if the mapping relation exists, the scheduling is performed directly according to the mapping relation, so that the processing link of the data stream is reduced, the processing speed can be increased, and the occupation of 5G network access terminal resources can be reduced.

According to the first aspect or any implementation manner of the first aspect, performing service identification on a data stream, and determining a service type identifier of a service corresponding to the data stream includes: performing service identification on the data flow, and determining an application providing the data flow; determining an application identification code corresponding to the application according to the mapping relation between the application and the application identification code; and determining the service type identification code of the service corresponding to the data stream according to the mapping relation between the application identification code and the service type identification code.

Therefore, according to the mapping relation between the application and the application identification code and the mapping relation between the application identification code and the service type identification code, the service type identification code of the service corresponding to the data stream can be accurately determined after the application of the data stream is determined.

In addition, the modification of the final result can be realized by the multi-level mapping relation without modifying each mapping relation, thereby facilitating the subsequent maintenance.

According to the first aspect, or any implementation manner of the first aspect, identifying a service for a data flow, and determining an application providing the data flow includes: extracting Internet protocol layer information and transmission layer information in a data stream; extracting characteristic information carried in Internet protocol layer information and transmission layer information; and performing big data matching processing on the characteristic information to determine the application for providing the data stream.

Illustratively, the feature information extracted from an Internet Protocol (IP) layer may be, for example, a source IP and a destination IP.

Illustratively, the characteristic information extracted from the transport layer may be, for example, source port, destination port, and IP/TCP protocol.

That is, the feature information extracted from the internet protocol layer information and the transport layer information may be, for example, quintuple information.

Therefore, by performing big data matching on the quintuple information, for example, matching the application corresponding to the quintuple information carried by the data stream in the mapping relation table/library between various quintuple information and applications pre-stored in the memory of the 5G CPE, the response of providing the data stream is determined. In this way, the application providing the data stream can be earned according to the exposed IP layer information and the transport layer information indicated without knowing the essential content of the data stream provided by the electronic equipment, i.e., without acquiring the privacy information of the user.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone.

The terms "first" and "second," and the like in the description and in the claims of the embodiments of the present application, are used for distinguishing between different objects and not for describing a particular order of the objects. For example, the first target object and the second target object, etc. are specific sequences for distinguishing different target objects, rather than describing target objects.

In the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

In the description of the embodiments of the present application, the meaning of "a plurality" means two or more unless otherwise specified. For example, a plurality of processing units refers to two or more processing units; the plurality of systems refers to two or more systems.

Before describing the technical solution of the embodiment of the present application, a process of completing one communication by an electronic device in a mobile communication system to which the embodiment of the present application is applied will be described with reference to the drawings.

First, in a 5G application scenario, electronic devices, such as mobile phones, tablet computers, personal computers, smart appliances, and the like, need to access a 5G wireless network via a 5G network access terminal (5G CPE).

The 5G CPE is used for dispatching data streams generated during the operation of the accessed electronic equipment to the 5G wireless network, and the 5G wireless network carries out service processing.

In order to better understand the process of completing one communication by an electronic device in a mobile communication system, the following description is made with reference to fig. 1.

Referring to fig. 1, exemplarily, a mobile phone a (electronic device) sends a message to a mobile phone B (electronic device), a data stream corresponding to the message sent by the mobile phone a first reaches a 5G CPE (a) connected to the mobile phone a, and then is sent to a base station a by the 5G CPE (a) through a network interface, the base station a performs a series of processing on the received data stream (signal), and then sends the data stream (signal) to a core network of an operator through a carrier network, the core network processes the data stream (signal), and sends the processed data stream (signal) to the base station B, and then the mobile phone B receives the data stream (signal) sent from the base station B by the 5G CPE (B).

Thus, handset a and handset B complete a communication.

Continuing with fig. 1, illustratively, in a 5G wireless network, the base station corresponds to an access network, and the bearer network responsible for transmitting information is called a bearer network, and the operator's core network is called a core network.

In addition, in order for an operator to separate a plurality of virtual end-to-end networks on a unified infrastructure, a network slicing (hereinafter referred to as 5G network slicing) technology has been developed.

Specifically, the 5G network slice is an on-demand networking manner, which enables an operator to separate a plurality of virtual end-to-end networks on a unified infrastructure, and each 5G network slice is logically isolated from an access network to a bearer network and then to a core network to adapt to various types of applications.

Furthermore, it can be understood that in a 5G network slice, at least three parts can be divided into a radio network sub-slice, a bearer network sub-slice and a core network sub-slice.

Based on the mobile communication system, the embodiment of the present application provides a data stream scheduling method applied to a 5G network access terminal, that is, a 5G CPE, in the mobile communication system, which aims to implement intelligent scheduling of data streams of different types of services to different network slices, so as to fully utilize a 5G communication network and complete a communication demand of a user diversified data stream.

Referring to fig. 2, the data flow scheduling method provided in this embodiment includes:

step S101, a data stream is received.

For example, the data stream in this embodiment is specifically from an electronic device, and the electronic device accesses the 5G wireless network through the 5G CPE.

Specifically, in this embodiment, the 5G CPE may include, for example, a receiving module.

Wherein, the receiving module is used for receiving the data stream provided by each electronic device which is connected to the 5G CPE.

By way of example, in a practical application scenario,

there may be multiple electronic devices accessing the 5G wireless network through the same 5G CPE, such as a mobile phone, a personal computer, a tablet, an intelligent sound, an intelligent appliance, and the like. Thus, there may be multiple data streams received by the receiving module, e.g., from different electronic devices, or from multiple electronic devices of the same electronic device.

For the implementation scenario, the data stream received by the receiving module is converged into an Internet Protocol (IP) Protocol stack of the 5G CPE, and then sequentially read from the IP Protocol stack and sent to the service identification module for service identification processing.

In addition, the data stream received by the receiving module is received and converged to the IP protocol stack through a driving module used by the electronic equipment.

Illustratively, the driving module may be, for example, ethernet, WiFi, bluetooth, etc.

In addition, in order to establish a routing path with each 5G network slice in the 5G wireless network, so as to access the electronic device to the 5G wireless network, the 5G CPE may further include a routing configuration module and a dialing module.

It should be noted that the 5G CPE accesses the 5G wireless network specifically by dialing, for example, by using a Packet Data Protocol (PDP) to access the 5G wireless network.

Specifically, in this embodiment, the 5G CPE accesses the 5G wireless network through PDP dialing, for example, the following three ways are available:

mode 1:

firstly, a dialing module receives configuration information corresponding to a 5G network slice issued by a 5G wireless network; then, the dialing module initiates a dialing request aiming at the 5G network slice to the 5G wireless network according to the configuration information; then, the dialing module receives an IP address of the 5G network slice issued by the 5G wireless network; then, the dialing module sends the IP address to a route configuration module; then, the route configuration module establishes a route path between the route configuration module and the 5G network slice according to the IP address, wherein the route path corresponds to a network interface; and finally, the routing configuration module records the mapping relation between the routing path and the 5G network slice.

Therefore, the dialing module can realize the establishment of the routing path between the 5G network access terminal and each 5G network slice according to the configuration information corresponding to the 5G network slice issued by the 5G wireless network, so that the data of the subsequent electronic equipment can be sent to the routing path through the network interface corresponding to the routing path, and further the corresponding 5G network slice is reached.

Mode 2:

firstly, a dialing module receives configuration information corresponding to a 5G network slice configured by a user through a dialing page displayed in a display interface of electronic equipment; then, the dialing module initiates a dialing request aiming at the 5G network slice to the 5G wireless network according to the configuration information; then, the dialing module receives an IP address of the 5G network slice issued by the 5G wireless network; then, the dialing module sends the IP address to a route configuration module; then, the route configuration module establishes a route path between the route configuration module and the 5G network slice according to the IP address, wherein the route path corresponds to a network interface; and finally, the routing configuration module records the mapping relation between the routing path and the 5G network slice.

Therefore, the dialing module can realize the establishment of routing paths between the 5G network access terminal and each 5G network slice according to the configuration information corresponding to the 5G network slice configured by the user through the dialing page, so that the data of the subsequent electronic equipment can be sent to the routing paths through the network interfaces corresponding to the routing paths, and further the corresponding 5G network slice is reached.

Mode 3:

firstly, a dialing module reads configuration information corresponding to a locally pre-stored 5G network slice; then, the dialing module initiates a dialing request aiming at the 5G network slice to the 5G wireless network according to the configuration information; then, the dialing module receives an IP address of the 5G network slice issued by the 5G wireless network; then, the dialing module sends the IP address to a route configuration module; then, the route configuration module establishes a route path between the route configuration module and the 5G network slice according to the IP address, wherein the route path corresponds to a network interface; and finally, the routing configuration module records the mapping relation between the routing path and the 5G network slice.

Therefore, the dialing module can realize the establishment of routing paths between the 5G network access terminal and each 5G network slice according to the configuration information corresponding to the pre-stored local 5G network slice, so that the data of the subsequent electronic equipment can be sent to the routing paths through the network interfaces corresponding to the routing paths, and further the corresponding 5G network slices are achieved.

It should be understood that the above description is only an example for better understanding of the technical solution of the present embodiment, and is not to be taken as the only limitation of the present embodiment.

Step S102, the data flow is identified, and the service type identification code of the service corresponding to the data flow is determined.

For example, in an actual application scenario, the data stream received by the 5G CPE from the electronic device is usually provided by an application running in the electronic device.

Further, different applications may correspond to different services. In order to classify the services, different services related in this embodiment may correspond to different service type identifiers.

Therefore, when the service type identifier of the service corresponding to the data stream is determined, the application providing the data stream may be determined first.

Based on this, the operation of step S102 described above can be realized by, for example, the following flow:

firstly, service identification is carried out on the data flow, and an application providing the data flow is determined.

Specifically, in the embodiment, the service identification performed on the data flow may be determined by IP layer information and transport layer information, for example.

Illustratively, in specific implementation, the IP layer information and the transport layer information in the data stream need to be extracted first; extracting characteristic information carried in the IP layer information and the transmission layer information; and finally, determining the application providing the data stream by performing big data matching processing on the characteristic information.

Illustratively, the feature information extracted from the IP layer may be, for example, a source IP and a destination IP.

That is, the feature information extracted from the IP layer information and the transport layer information may be, for example, quintuple information.

Therefore, by performing big data matching on the quintuple information, for example, matching the application corresponding to the quintuple information carried by the data stream in the mapping relation table/library between various quintuple information and applications pre-stored in the memory of the 5G CPE, the response of providing the data stream is determined. Therefore, the application for providing the data stream can be accurately determined according to the IP layer information and the transmission layer information exposed on the surface without knowing the essential content of the data stream provided by the electronic equipment, namely without acquiring the privacy information of the user.

It can be understood that for some servers with application having unique destination IP and destination port, the service identification of the data stream may be determined according to the destination IP only; for some destination IPs corresponding to multiple destination ports, the application providing the data stream needs to be determined according to the feature information of both the destination IP and the destination ports.

It should be understood that the above description is only an example for better understanding of the technical solution of the present embodiment, and is not intended to limit the present embodiment. In practical application, in order to perform service identification on a data stream as accurately as possible, feature information of an application layer in the data stream may be extracted, and then an application providing the data stream is determined by performing big data matching on the feature information of the application layer. In practical application, the characteristic information required by the identification can be determined according to an identification library constructed by big data analysis.

In addition, as for the above-mentioned recognition library, in some examples, the recognition library may be obtained by analyzing and processing mass data collected by a big data platform according to a preset machine learning algorithm, that is, feature information of data streams provided by applications of various service types is recorded in the recognition library.

And then, determining the application identification code corresponding to the application according to the mapping relation between the application and the application identification code.

And finally, determining the service type identification code of the service corresponding to the data stream according to the mapping relation between the application identification code and the service type identification code.

It should be noted that, in this embodiment, the mapping relationship between the application and the application identifier, the mapping relationship between the application identifier and the service type identifier, and the mapping relationship between the service type identifier and the 5G network slice in step S103 are specifically constructed by training a sample data stream collected by a big data platform based on a preset machine learning algorithm, so that it is ensured that the three constructed mapping relationships can cover all applications in the current market as much as possible, and further, after the 5G CPE receives the data stream sent by the electronic device, it can be quickly and accurately determined to which network interface the data stream needs to be scheduled.

And step S103, determining a target 5G network slice matched with the data stream according to the mapping relation between the service type identification code and the 5G network slice.

It can be understood that the 5G communication network brings three core application scenarios, namely, eMBB, urrllc, and mtc, and in order to satisfy these three types of 5G application scenarios, the 5G wireless network may be divided into an eMBB network slice, a urrllc network slice, and an mtc network slice, so as to process data streams of different service types.

The so-called eMBB, Enhanced Mobile Broadband (Enhanced Mobile Broadband), has the characteristics of greater network throughput, peak rate and low delay, and is mainly directed to services such as games and videos in practical applications.

The mtc is a Massive machine type Communication (Massive machine type Communication), and has a huge connection number to support the characteristics of Massive Internet of Things (IoT) devices, and in practical applications, the mtc mainly aims at Internet of Things (Internet of Things, abbreviated as IoT) devices.

The so-called urrllc, i.e. high-reliability and Low-Latency Communication, is responsible for high-reliability and Ultra-Low Latency of a core concerned network, and mainly aims at services such as audio and video conferences in practical application.

In addition, it should be understood that the IoT devices may be various smart devices that can access a 5G wireless network, such as a smart audio, a refrigerator, an air conditioner, and a television.

The use of 5G CPE in the three application scenarios described above is illustrated, for example, in fig. 3.

For example, in practical applications, the service types corresponding to the three core application scenarios may be as shown in table 1, for example.

Table 1 application scenarios corresponding to three types of network slices

The three types of mapping relationships according to the present embodiment are described below in tables 2 to 4.

Table 2 mapping relation table between application and application identification code

Table 3 mapping relation table between application identification code and service type identification code

Table 4 table of mapping relationship between service type identification code and 5G network slice

For example, when the data stream is provided by the game application 1, the application identification code of the application may be determined to be 100 according to the mapping relationship in table 2.

Further, after determining that the application identifier of the application providing the data stream is 100, the service type identifier of the service corresponding to the data stream may be determined to be 4 according to the mapping relationship in table 3.

Further, after the service type identifier of the service corresponding to the data flow is determined to be 4, the target 5G network slice matched with the data flow may be determined to be the eMBB network slice according to the mapping relationship in table 4.

Furthermore, it is understood that in practical applications, in order to reduce the number of mapping tables and avoid data redundancy, the contents of the above tables 2 to 4 may be plotted in one mapping table, for example, as shown in table 5.

TABLE 5 mapping relationship table between applications, application identifiers, service type identifiers, 5G network slices

In addition, it can be understood that in practical application, through training and identification of mass big data by a machine learning algorithm, various service types such as games, payment and application markets related to the table above can be identified, short videos, live broadcasts, news, social chatting, visual calls/conferences, shopping, life and online learning can also be identified.

Correspondingly, in order to facilitate the construction of the subsequent mapping relation table, different service type identification codes can be allocated to the different service types according to service requirements, for example, the service type identification code corresponding to the application market class is "2", the service type identification code corresponding to the game class is "4", the service type identification code corresponding to the short video class is "8", the service type identification code corresponding to the video class is "16", the service type identification code corresponding to the live broadcast class is "32", the service type identification code corresponding to the news class is "64", the service type identification code corresponding to the social chat class is "128", the service type identification code corresponding to the visual communication/conference class is "256", the corresponding service type identification code is "512", the service type identification code corresponding to the payment class is "1024", and the service type identification code corresponding to the life class is "2048", the service type identification code corresponding to the online learning class is 4096.

Further, each service type application may correspond to different application identification codes, for example, the application identification code corresponding to the game application 1 in the table is "100", the application identification code corresponding to the game application 2 is "101", the application identification code corresponding to the payment application 1 is "502", the application identification code corresponding to the payment application 2 is "504", the application identification code corresponding to the application market application 1 is "2", and the application identification code corresponding to the application market application 2 is "4".

In addition, it should be noted that, specifically in this embodiment, the 5G CPE further includes a service identification module.

Correspondingly, the service identification module is used for reading the data stream from the IP protocol stack, performing service identification on the read data stream, and determining a service type identification code of a service corresponding to the data stream. Meanwhile, the service identification module is also used for determining a target 5G network slice matched with the data stream according to the mapping relation between the service type identification code and the 5G network slice.

And step S104, scheduling the data stream to a network interface corresponding to the target 5G network slice.

It should be noted that the Network interface, i.e., a Wide Area Network (WAN) interface, referred to in this embodiment may also be understood as a device interface of a device, i.e., a 5G CPE.

Illustratively, as can be seen from the above description, in a 5G communication network, 5G application scenarios are divided into an eMBB application scenario, an mtc application scenario and a urrllc application scenario. Data flow under an eMBB application scene generally needs to be scheduled to a 5G wireless network of an eMBB network slice group network, data flow under an mMTC application scene generally needs to be scheduled to a 5G wireless network of an mMTC network slice group network, and data flow under an uRLLC application scene generally needs to be scheduled to a 5G wireless network of a uRLLC network slice group network.

Therefore, in order to realize the scheduling of data streams of different service types on the matched 5G network slice, the WAN interface on the 5G CPE can be divided into these several types.

Referring to fig. 4, for example, WAN interface eth _ x1 corresponds to an eMBB network slice, WAN interface eth _ x2 corresponds to an mtc network slice, and WAN interface eth _ x3 corresponds to a urrllc network slice.

In addition, it should be noted that, specifically in this embodiment, the 5G CPE further includes a scheduling management module.

Accordingly, the schedule management module is configured to schedule the data flow to a network interface corresponding to the target 5G network slice.

For example, when the determined target 5G network slice is an eMBB network slice, according to the mapping relationship between the network interface and the 5G network slice shown in fig. 4, the data stream is specifically scheduled to the WAN interface eth _ x1 by the scheduling management module, and then the data stream is sent to the eMBB network slice through the routing path established between the 5G CPE and the eMBB network slice.

In addition, specifically, in this embodiment, before the step S104 is executed, it is determined whether the quintuple information corresponding to the data stream has the scheduling flag already set.

Accordingly, if the scheduling flag has been set, the data flow is scheduled to the network interface corresponding to the target 5G network slice; otherwise, scheduling the data stream to a network interface corresponding to the default 5G network slice.

Illustratively, regarding the default 5G network slice, it may be an eMBB network slice in some examples, for example.

Accordingly, the network interface corresponding to the default 5G network slice may be the WAN interface eth _ x1 in fig. 4.

Illustratively, regarding the default 5G network slice, in some examples, it may be an mtc network slice, for example.

Accordingly, the network interface corresponding to the default 5G network slice may be the WAN interface eth _ x2 in fig. 4.

Regarding default 5G network slices, in some examples, it may be, for example, a uRLLC network slice.

Accordingly, the network interface corresponding to the default 5G network slice may be the WAN interface eth _ x3 in fig. 4.

In addition, it should be noted that, the above-mentioned determining whether the quintuple information corresponding to the data stream has set the scheduling flag may be, for example, by determining whether the quintuple information corresponding to the data stream has already established a mapping relationship with the network interface corresponding to the target 5G network slice in practical application. That is, the process of setting the scheduling flag is essentially a process of establishing a mapping relationship between the quintuple information and the network interface corresponding to the target 5G network slice.

Further, for a scenario where it is determined that the data stream matches the target 5G network slice this time, but the scheduling flag is not set yet (for example, after the electronic device accesses the 5G CPE, the quintuple information in the data stream sent to the 5G CPE for the first time is not set with the scheduling flag), in order to ensure that the data stream provided by the application providing the data stream next time and including the same quintuple information can be scheduled to the matching target 5G network slice instead of being scheduled to the network interface corresponding to the default 5G network slice. Before scheduling the data stream of the target 5G network slice that has been determined to be matched to the network interface corresponding to the default 5G network slice, connection trace information (conntrack) of the data stream may be cleared first, and then a mapping relationship between the quintuple information and the network interface corresponding to the target 5G network slice is established, that is, a scheduling flag is set for the quintuple information.

Therefore, before a new data stream reaches the 5G CPE and the service identification module identifies the service, whether the newly received data stream can be directly dispatched to the network interface corresponding to the matched target 5G network slice or not can be determined by judging whether the quintuple information of the data stream needing service identification is set with the dispatching mark or not, namely whether the quintuple information corresponding to the data stream is in mapping relation with the network interface corresponding to the target 5G network slice or not.

Accordingly, when the five-tuple information has established a mapping relationship with the network interface corresponding to the target 5G network slice, the step of scheduling the data stream to the network interface corresponding to the target 5G network slice is performed according to the mapping relationship, that is, the operations of step S102 and step S103 are skipped, and the operation of step S104 is directly performed. Otherwise, when the mapping relationship between the five tuple information and the network interface corresponding to the target 5G network slice is not established, the operations from step S102 to step S104 are sequentially performed.

Therefore, as the data stream which is scheduled to a specific network interface is provided with the scheduling label, namely the mapping relation between the quintuple information and the target 5G network slice is established, whether the mapping relation exists is judged before the service identification is carried out on the received data stream, if the mapping relation exists, the scheduling is directly carried out according to the mapping relation, thereby reducing the processing link of the data stream, not only increasing the processing speed, but also reducing the occupation of the 5G network access terminal resources.

In addition, it should be noted that, in practical application, conntrack is data stream information maintained by the kernel protocol stack itself, and for each data stream, conntrack corresponds to the data stream information. The emptying is to trigger rescheduling when the next data stream enters the TCP/IP protocol stack, and conntrack is a routing basis for data scheduling.

In addition, specifically in this embodiment, if the service identification module does not determine the target 5G network slice matched with the data stream to be scheduled this time, for example, because the application providing the data stream cannot be determined, the application identification code cannot be determined, the service type identification code cannot be determined according to the application identification code, and finally the target 5G network slice cannot be determined according to the service type identification code, in order to ensure that the data stream reaching the 5G CPE can be normally scheduled in the 5G wireless network, the data stream may be scheduled to a network interface corresponding to the default 5G network slice.

In addition, it should be understood that, specifically in practical applications, when the data stream scheduling method provided by the present embodiment is used to schedule a data stream from an electronic device, the processing flow of the method is, for example:

first, a data stream is received.

Then, carrying out service identification on the data stream;

then, when the service corresponding to the data stream is a first service, scheduling the data stream to a network interface corresponding to a first 5G network slice; and when the service corresponding to the data stream is the second service, scheduling the data stream to a network interface corresponding to the second 5G network slice.

In addition, in order to implement the scheduling of the data stream, before receiving the data stream, the 5G CPE does not receive the setting of the mapping relationship between the first service and the first 5G network slice and the setting of the mapping relationship between the second service and the second 5G network slice by the user. Namely, the user is not required to manually configure the 5G network slices corresponding to different services.

Therefore, according to the data stream scheduling method provided by the embodiment, the electronic device is accessed to the 5G wireless network through the 5G network access terminal, so that the electronic device can work in the 5G wireless network, and the service processing speed is faster.

In order to better understand the data stream scheduling method applied to the 5G CPE provided in the embodiment of the present application, specific descriptions are provided below from the perspective of a kernel protocol stack in the 5G CPE and functional modules inside the 5G CPE.

Referring to fig. 5, for example, in the kernel IP protocol stack (or TCP/IP protocol stack) of the 5G CPE, the Netfilter framework schedules the data flow through 5 key detection points (hooks).

Specifically, Netfilter is a subsystem introduced by Linux 2.4.x, which serves as a generic, abstract framework that provides a complete set of management mechanisms for hook functions, enabling such functions as data flow (packet) filtering, Network Address Translation (NAT), and protocol type-based connection tracing.

Continuing with FIG. 5, exemplary, the above-mentioned 5 key hook points are PRE _ ROUTING, LOCAL _ IN, LOCAL _ OUT, Forward, and POST _ ROUTING, respectively.

Specifically, in this embodiment, after the data stream provided by the electronic device connected to the 5G CPE is sent to the 5G CPE through the driver module of the electronic device, the data stream may pass through three key hook points, namely PRE _ ROUTING, Forward, and POST _ ROUTING.

In addition, it should be noted that, in this embodiment, the service identification module in the 5G CPE specifically operates at a FORWARD point, and after a data stream from the electronic device passes through a PRE _ ROUTING point and then is decided by a ROUTING decision function, if it is determined that the currently incoming data stream needs to be sent to the 5G wireless network, that is, an external network is accessed, the data stream will flow into the FORWARD point, and then the service identification module located at the FORWARD point performs service identification on the data stream.

With continued reference to fig. 5, the traffic identification performed by the exemplary traffic identification module on the data flow may be roughly divided into two steps. Analyzing IP information in a data stream to obtain quintuple information corresponding to the data stream, and storing the obtained quintuple information in a memory for subsequent use; and secondly, identifying the type of the service corresponding to the data stream, and associating the identification result with the quintuple information stored in the memory in the previous step, namely establishing a mapping relation between the quintuple information and the target 5G network slice corresponding to the identified service type identifier.

Correspondingly, after the service identification module identifies the service of the data stream, the service identification module dispatches the data stream to a POST _ ROUTING point through the dispatching management module and finally sends the data stream to the 5G wireless network through the POST _ ROUTING point.

Continuing with fig. 5, exemplarily, if it is determined by the routing decision function that the data stream processed this time is a data stream that needs to be processed inside the 5G CPE, for example, address allocation and access to an internal web page, the data stream flows into the internal four layers or more of protocol stacks through the LOCAL _ IN point, and the data stream processed by the four layers or more of protocol stacks is processed by the routing decision function again, so as to determine whether the data stream is returned to the electronic device or discarded inside.

With continued reference to FIG. 5, if the data stream is to be returned to the electronic device, then it flows to LOCAL _ OUT.

Accordingly, if the data stream flows to LOCAL _ OUT, the processed data stream is finally returned to the electronic device.

It should be noted that, in practical applications, the processed data stream may not be the same as the content carried by the received data stream, for example, if the data stream sent by the electronic device is a request for connecting to the 5G wireless network, the request may be processed inside the 5G CPE and not sent to the external network.

Accordingly, after processing by the 5G CPE, the data flow to the LOCAL _ OUT point is essentially a response message based on the request to connect to the 5G wireless network.

As can be seen from the above description of fig. 5, the Netfilter framework places detection points (hooks) at several positions of the whole network flow, and registers some processing functions at each detection point for processing.

The processing functions registered at the above 5 key hook points are essentially the receiving module, the service identification module, the scheduling management module, and the like included in the 5G CPE in this embodiment.

Referring to fig. 6, the receiving module for receiving the data stream from the electronic device is located at the PRE _ ROUTING point, and the service identification module for identifying the service of the data stream to be sent to the external network is located at the FORWARD point.

As shown in fig. 6, in practical application, the mapping relationship maintained and managed by the scheduling management module may also be preset in advance, so that the scheduling management module may be located between FORWARD point and POST _ ROUTING point, and then after the service identification module located at FORWARD point performs service identification on the data stream to obtain an identification result, the data stream is scheduled by the scheduling management module, and finally, the data stream may be scheduled to the network interface corresponding to the matched 5G network slice, and sent to the 5G wireless network through POST _ ROUTING.

IN addition, after the data stream received by the receiving module is processed by the routing decision function, the data stream flowing into the four layers and above protocol stack reached by the LOCAL _ IN point can be connected to the application layer management Web corresponding to the request of the 5G wireless network, for example.

Accordingly, in response to the request, the application layer management Web may display the content shown in fig. 7 on the display interface of the electronic device after the response message is fed back to the electronic device via the LOCAL _ OUT.

Referring to fig. 7, a display interface of an electronic device may illustratively include one or more options in a page 100.

For example, the web site information corresponding to page 100, and an "exit log in" option for exiting the current page.

With continued reference to FIG. 7, page 100 may also include a "Home" option, an "I go to Net" option, a "My WiFi" option, a "terminal management" option, and a "more functions" option.

Where page 100 displays 101 the contents of the page when the "home" option is selected.

Exemplarily, 101 in fig. 7 indicates that the electronic device (terminal device) does not access the 5G wireless network.

Further, if the user selects the "my WiFi" option in fig. 7, the electronic device will switch the page 100 displayed on the display interface to the page 200 shown in fig. 8 in response to the user's manipulation.

Referring to fig. 8, for example, the page 200 may include a control 201 for setting dual-frequency preference, a control 202 for turning on WiFi, a control 203 for setting WiFi name, a control 204 for selecting security mode, a control 206 for setting whether WiFi password is visible, a control 206 for setting WiFi standby network, and a save control.

After the control 201 is turned on, that is, in the state shown in fig. 8, it indicates that the WiFi dual bands of the 2.4G band and the 5G band are integrated, and the 5G CPE field selects the faster WiFi band.

Accordingly, if the control 201 is turned off, that is, in the state of the control 206 in fig. 8, the user can set the WiFi frequency band used when accessing the 5G wireless network by himself, for example, set the 2.4G frequency band or the 5G frequency band to be used all the time.

With continued reference to fig. 8, when the control 202 is turned on, i.e., in the state shown in fig. 8, it indicates that the user desires the electronic device to connect to the 5G wireless network via the WiFi driver.

Illustratively, in some examples, controls 203, 204, 205, and 206 displayed in page 200 may not be operable by the user until control 202 is opened.

Accordingly, the control 203 is used for the user to set a name for WiFi, the control 204 is used for the user to select a security mode, and the security mode shown in fig. 8 is WPA2 PSK mode.

For example, in practical applications, the user may click the control 204 to select the security mode in the pop-up security mode selection list.

It can be understood that the above-mentioned security mode is essentially an encryption mode for the password. At present, the encryption mode of the WiFi password comprises three modes, namely WPA-PSK/WPA2-PSK, WPA/WPA2 and WEP.

For specific applications of the above three encryption methods, reference may be made to relevant literature, and details are not repeated here.

With continued reference to fig. 8, when the control 205 is in the state shown in fig. 8, it indicates that the current WiFi password is not visible.

Accordingly, if the control 205 is clicked once again in the state shown in fig. 8, the WiFi password may be changed from invisible to visible.

With continued reference to fig. 8, when the control 206 is turned on, the electronic device that cannot scan the WiFi6 signal for the network card driver can access the 5G wireless network through the WiFi standby network (WiFi 5 signal).

It should be noted that the WiFi6, i.e., the sixth generation wireless network technology, is the name of the WiFi standard. Is a wireless local area network technology that the WiFi alliance has established in the IEEE 802.11 standard. WiFi6 allows communication with up to 8 devices, up to 9.6 Gbps. Compared with the existing common WiFi5 technology, namely the sixth generation wireless network technology, WiF6 has better performance in transmission rate, access quantity and energy consumption reduction. In the daily performance test, the transmission data of the conventional WiF5 can reach about 500mbps, and the transmission data of WiF6 can reach about 800mbps, which is improved by about 50%.

Accordingly, after completing the setting of each control, if the user clicks the "save" control, the electronic device responds to the user operation and sends the information set in the page 200 to the 5G CPE as a new data stream, and further connects to the 5G wireless network.

In addition, the processing flow of the data stream scheduling method provided by this embodiment, specifically to the receiving module, the service identification module and the scheduling management module inside the 5G CPE, is as shown in fig. 9 and fig. 10.

Referring to fig. 9, assume that an electronic device connected to the 5G CPE sends data stream 1 to the receiving module in the 5G CPE through the driving module; then, after receiving the data stream 1, the receiving module transfers the data stream 1 to an IP protocol stack; then, the data stream 1 read from the IP protocol stack is transferred to the scheduling flag identification module, and the scheduling flag identification module determines whether the data stream 1 has a scheduling flag, that is, whether the quintuple information of the data stream 1 establishes a mapping relationship with a specific 5G network slice.

Correspondingly, if the data stream 1 has no scheduling mark, the service identification module identifies the service of the data stream 1, and the scheduling management module schedules the data stream 1 to a network interface corresponding to the default 5G network slice after the identification is completed; if the data stream 1 has the scheduling mark, the data stream 1 is directly scheduled to the network interface corresponding to the marked target 5G network slice by the scheduling management module.

It should be noted that, if the data stream 1 has a scheduling flag, when the scheduling management module schedules the data stream 1 to the network interface corresponding to the marked target 5G network slice, the data stream is sent to the target 5G network interface through the WAN interface corresponding to the target 5G network slice according to the mapping relationship between the 5G network slice and the network interface shown in fig. 4.

For example, when the data stream 1 is a data stream provided by a game-class application, it is scheduled to "WAN interface eth _ x 1" in fig. 4.

Also for example, when data stream 1 is a data stream provided by an IoT device, it is scheduled to "WAN interface eth _ x 2" in fig. 4.

Also for example, when the data stream 1 is a data stream provided by an application of the audio video conference class, it is scheduled to "WAN interface eth _ x 3" in fig. 4.

In addition, if the data stream 1 is not set with the scheduling flag, before the data stream is scheduled to the network interface corresponding to the default 5G network slice by the scheduling management module, by adopting the technical scheme provided by this embodiment, the data stream 1 is forwarded to the service identification module for service identification, and after the service identification is performed by the service identification module, the data stream is forwarded to the scheduling management module, and is scheduled to the network interface corresponding to the default 5G network slice by the scheduling management module.

With regard to the implementation of the above scenario, referring to fig. 10, the traffic identification module identifies data flow 1.

It can be understood that the service identification module in this embodiment identifies the data stream 1, that is, identifies whether the data stream 1 has a matching target 5G network slice in the above embodiment.

Correspondingly, when an identification result exists (the data stream 1 has a matched target 5G network slice), clearing the connection tracking information, establishing a mapping relation between the quintuple information of the data stream 1 and the determined target 5G network slice, namely setting a scheduling mark, then transferring the data stream 1 to a scheduling management module, and scheduling the data stream 1 to a network interface corresponding to the default 5G network slice by the scheduling management module. Thus, when the data stream 2 carrying the same quintuple information as the data stream 1 reaches the 5G CPE next time, the scheduling management module can directly schedule the network interface corresponding to the marked target 5G network slice by identifying that the scheduling mark is already set for the quintuple information.

In addition, if the identification result of the data stream 1 is not obtained through the identification of the service identification module, the data stream 1 is transferred to the scheduling management module, and the scheduling management module schedules the data stream 1 to a network interface corresponding to the default 5G network slice. In this way, data streams for which the target 5G network slice cannot be determined can also be normally transmitted to the 5G wireless network.

Therefore, in the data stream scheduling method provided by this embodiment, the service identification module is used for identifying and processing the data stream, and different types of application services are intelligently scheduled to different 5G network slice services, so that the purpose of making full use of the 5G communication network and completing communication requests of user diversified data streams is achieved.

With reference to the timing diagrams of interaction among the electronic device, the 5G CPE, and the 5G wireless network shown in fig. 11 and fig. 12, a process of establishing a routing path from the 5G CPE and a 5G network slice in the 5G wireless network to receiving a data stream provided by the electronic device and scheduling the data stream to the 5G wireless network in a scenario to which the data stream scheduling method provided in this embodiment is applied will be described below.

It should be noted that the ways in which the 5G CPE accesses the 5G network slice in the 5G wireless network can be roughly divided into three types.

For example, as shown in step S201 in fig. 11, a manner is that configuration information of a 5G network slice in a 5G wireless network that needs to establish a routing path with a 5G CPE is actively issued by the 5G wireless network to a dialing module in the 5G CPE.

For example, the 5G wireless network may send configuration information of an eMBB network slice to the dialing module, send configuration information of an mtc network slice to the dialing module, and send configuration information of a urrllc network slice to the dialing module.

Illustratively, another way is shown as step S202 in fig. 11, that is, the configuration information of the network slice is preset in the memory of the 5G CPE.

It should be noted that, for the manner of step S202, after the 5G CPE is powered on, step S204 is automatically triggered to be executed, and an operation of establishing a routing path between the 5G CPE and a 5G network slice in the 5G wireless network is executed.

Illustratively, another way is as shown in step S203 in fig. 11, that is, the configuration information of the network slice is configured by the User through a web product Interface (WebUI) in the electronic device, for example, a dialing page, to configure the configuration information of each 5G network slice, and then the configuration information of the configured network slice is sent to the dialing module of the 5G CPE.

It can be understood that, in practical applications, the configuration of the configuration information of the 5G network slice can be implemented in any one of the steps S201 to S203.

Accordingly, after the configuration information of the 5G network slice is obtained in any of the above manners, step S204 is triggered to be executed, and the operation of establishing the routing path between the 5G CPE and the 5G network slice in the 5G wireless network is executed.

The process of establishing a routing path between the 5G CPE and the 5G network slice in the 5G wireless network according to the configuration information of the 5G network slice may be implemented by, for example, step S204 to step S209 in fig. 11.

With reference to fig. 11, when the configuration information of the 5G network slice is obtained and step S204 is triggered to be executed, the dialing module reads the obtained configuration information of the 5G network slice, and then initiates a dialing request to the 5G wireless network according to the read configuration information of the 5G network slice, that is, executes the operation of step S205.

Correspondingly, after receiving the dialing request initiated by the dialing module in the 5G CPE, the 5G wireless network returns the IP address of the 5G network slice corresponding to the configuration information to the dialing module in response to the request, that is, executes step S206.

With reference to fig. 11, after receiving the IP address of the 5G network slice sent by the 5G wireless network, the dialing module sends the IP address to the route configuration module in the 5G CPE, that is, executes step S207.

With reference to fig. 11, after the routing configuration module receives the IP address of the 5G network slice sent by the dialing module, a routing path between the 5G CPE and the 5G network slice corresponding to the IP address is established, that is, step S208 is executed.

In addition, after the routing path between the 5G CPE and the 5G network slice corresponding to the IP address is established, the routing configuration module further executes step S209 in fig. 11, that is, records a mapping relationship between the currently established routing path and the 5G network slice (for convenience of subsequent description, the mapping relationship between the established routing path and the 5G network slice is hereinafter referred to as mapping relationship 1), so that when data stream scheduling is performed subsequently, it can be determined which routing path the data stream is sent to the target 5G network slice according to mapping relationship 1.

Correspondingly, in order to enable the subsequent 5G CPE to receive the data stream from the electronic device, the scheduling management module can send the data stream to the 5G wireless network through the determined routing path corresponding to the 5G network slice according to the mapping relationship 1, and the routing configuration module can actively send the mapping relationship 1 to the scheduling management module after recording the mapping relationship 1, that is, step S210 is executed, or when the scheduling management module needs to send the data stream to the 5G wireless network, the scheduling management module actively sends a request for obtaining the mapping relationship 1 to the routing configuration module, or queries the routing path corresponding to the 5G network slice corresponding to the data stream.

Accordingly, the route configuration module returns a message of the route path corresponding to the determined 5G network slice to the schedule management module in response to the request.

In addition, it should be noted that, in practical applications, a routing path between the 5G CPE and one 5G network slice is established by one dialing request, and therefore, for the above three mentioned core application scenarios, the dialing module needs to initiate a dialing request at least three times, so as to obtain an IP address corresponding to the eMBB network slice, an IP address corresponding to the mtc network slice, and an IP address corresponding to the urrllc network slice, and further establish routing paths between the 5G CPE and the eMBB network slice, the mtc network slice, and the urrllc network slice according to the IP addresses of the three 5G network slices.

In addition, it should be understood that, in practical applications, there may be a case where the service identification module cannot identify the 5G network slice corresponding to the data stream, and therefore, in order to normally send the data stream, for which the 5G network slice cannot be identified, to the 5G wireless network, the three types of 5G network slices may be set as default 5G network slices according to service requirements. In this way, the data stream without the identification result can be scheduled to the network interface corresponding to the default 5G network slice, and sent to the 5G wireless network through the routing path corresponding to the 5G network slice.

Thus, the establishment of a routing path between the 5G CPE and the 5G wireless network is realized.

Referring to fig. 12, after the routing path between the 5G CPE and the 5G wireless network is established, if the user uses an application installed in the electronic device, a data stream 1 provided by the application is transmitted to the receiving module of the 5G CPE, i.e., step S211.

Accordingly, after receiving the data stream 1, the receiving module sends the data stream 1 to the scheduling flag identifying module, that is, executes step S212.

Accordingly, the scheduling flag identifying module determines whether the data stream 1 has a scheduling flag, i.e. step S213 is executed.

Specifically, if it is determined that the data stream 1 has been set with the scheduling flag after being identified by the scheduling flag identifying module, for example, the quintuple information corresponding to the data stream 1 has established a mapping relationship with the matched target 5G network slice, step S214 is executed to send the data stream 1 to the scheduling management module, that is, the scheduling management module performs the scheduling directly without performing service identification again.

Step S215, determining a target 5G network slice corresponding to the scheduling flag.

It can be understood that, as can be seen from the description of the foregoing embodiment, the scheduling flag set for the data stream 1 is actually a mapping relationship between five tuple information of the data stream 1 and the target 5G network slice, so that the target 5G network slice corresponding to the data stream 1 can be determined according to the scheduling flag.

And step S216, dispatching the data stream 1 to a WAN interface corresponding to the target 5G network slice.

It can be understood that, as can be understood from the above description of the embodiment, the 5G network slices are divided into three classes according to three application scenarios provided by the 5G network, and each class of 5G network slice corresponds to one WAN interface, for example, as shown in fig. 4. Therefore, after the target 5G network slice is determined, according to the mapping relationship between the 5G network slice and the network interface shown in fig. 4, the WAN interface corresponding to the currently determined target 5G network slice may be determined.

Therefore, according to the mapping relationship between the 5G network slice and the WAN interface shown in fig. 4, the data stream 1 can be scheduled to the WAN interface corresponding to the target 5G network slice.

For example, for the determined target 5G network slice being an eMBB network slice, data flow 1 is scheduled to WAN interface eth _ x 1.

Also for example, for the determined target 5G network slice being an mtc network slice, data flow 1 is scheduled to WAN interface eth _ x 2.

Also for example, for the determined target 5G network slice being the urrllc network slice, data flow 1 is scheduled to WAN interface eth _ x 3.

Step S217, according to the mapping relationship 1, sending the data stream 1 to the 5G wireless network through the routing path corresponding to the target 5G network slice.

Illustratively, assume mapping 1 is shown below in Table 6:

TABLE 6 mapping relation 1

Based on the mapping relation 1 shown in table 6, if the determined target 5G network slice is the eMBB network slice, the data flow 1 is specifically sent to the 5G wireless network through the routing path 1.

Accordingly, if the determined target 5G network slice is an mtc network slice, data flow 1 is specifically sent to the 5G wireless network through routing path 2.

Accordingly, if the determined target 5G network slice is a urrlc network slice, the data flow 1 is specifically sent to the 5G wireless network via the routing path 3.

Continuing with fig. 12, if it is determined that the data stream 1 is not set with the scheduling flag after being identified by the scheduling flag identifying module, for example, the quintuple information corresponding to the data stream 1 does not establish a mapping relationship with the matched target 5G network slice, step S218 is executed to send the data stream 1 to the service identifying module.

Specifically, after receiving the data stream 1, the service identification module performs service identification on the data stream 1, that is, executes step S219.

Correspondingly, after the service identification module identifies the service of the data stream 1, if no identification result is obtained, step S221 is executed, that is, the data stream 1 is sent to the scheduling management module, the scheduling management module schedules the data stream 1 to the WAN interface corresponding to the default 5G network slice, and sends the data stream 1 to the 5G wireless network through the routing channel corresponding to the default 5G network slice according to the mapping relation 1, that is, step S222 and step S223 are executed.

It should be noted that the identified result in this embodiment means that after the service identification module identifies the service of the data stream 1, the target 5G network slice matched with the service corresponding to the data stream 1 can be determined.

Correspondingly, the non-recognition result means that after the service recognition module performs the service recognition on the data stream 1, the target 5G network slice matched with the service corresponding to the data stream 1 cannot be determined, and in this case, the data stream 1 can only be processed by the default 5G network slice, so that the data stream 1 is scheduled to be the WAN interface corresponding to the default 5G network slice.

With reference to fig. 12, after the service identification module identifies the service of the data stream 1, if the identification result is obtained, that is, the target 5G network slice matching the service corresponding to the data stream 1 is determined, step S224 is executed.

Step S224, the service identification module clears the connection tracking information.

Step S225, the service identification module sets a scheduling flag.

Step S226, the service identification module sends the data stream 1 to the scheduling management module.

Specifically, the connection tracking information is cleared, a mapping relationship is established between quintuple information of the data stream 1 and the determined target 5G network slice, that is, a scheduling flag is set, then the data stream 1 is sent to the scheduling management module, and the scheduling management module schedules the data stream 1 to a network interface corresponding to the default 5G network slice, that is, step S222 and step S223 are executed. Thus, when the data stream 2 carrying the same quintuple information as the data stream 1 reaches the 5G CPE next time, the scheduling mark identification module identifies that the scheduling mark is set for the quintuple information, so that the scheduling management module can directly schedule the network interface corresponding to the marked target 5G network slice.

For example, if the default 5G network slice is the mtc network slice, data flow 1 would be scheduled to WAN interface eth _ x2 in fig. 4.

Therefore, the data stream can be automatically dispatched to the matched network interface without manually presetting the corresponding relation between the service type corresponding to the data stream and the network interface, and the intelligent dispatching management of the 5G network slice under the 5G wireless network is realized.
