Fig. 1 is a block diagram of a data transmission system according to an embodiment of the present application, and as shown in fig. 1, the data transmission system 100 includes: a policy control function entity 102, a session management function entity 104, and a user plane function entity 106, where the user plane function entity is configured to detect a scheduling priority of a data stream in a core network; under the condition that the scheduling priority is different from the resource scheduling priority of the default bearer, informing the policy control function entity and the session management function entity to establish a special bearer; the system comprises a policy control function entity and a session management function entity, wherein the policy control function entity and the session management function entity are used for receiving a first message sent by a user plane function entity, and the first message comprises an indication for establishing a special bearer; establishing a proprietary bearer on a core network according to a first message; the data stream is transmitted over a proprietary bearer, wherein the access address contained in the data stream is the address of a specific service.

In the data transmission system, the core network may be a 5G core network, and in order to achieve speed improvement of a specific service on the 5G network, the most important link is to correctly trigger establishment of a Non-GBR bearer of 5QI =7 in the 5G core network, where the Non-GBR bearer is the above-mentioned special bearer, and when there is data stream transmission in the 5G core network, an arriving data stream is detected by a user plane functional entity to obtain a target access address or a target URL address in the data stream, or according to a scheduling priority carried in the target access address or the target URL address, the scheduling priority may be represented by a 5QI value. If the target access address or the target URL address of the current data stream is an address in the preconfigured address table, the data stream has a higher resource scheduling priority, it should be noted that an address with a high resource scheduling priority, for example, a server IP address of the specific application, is stored in the preconfigured address table, the IP address of the specific application is configured in the 5G core network SMF network element, and the dedicated bearer related configuration of 5qi =7 is completed in the SMF/PCF, the 5G base station completes the resource reservation and the priority scheduling configuration of 5qi =7, for example, the priority scheduling ratio of 5qi =6/7/8/9 is preset to be 4.

If a user uses a specific application under 5G, the numerical value of 5QI carried in a data stream corresponding to the specific application is a preset value, for example, 5QI =7,5G core network UPF network element reports the data stream to PCF network element after detecting the data stream, the 5G core network detects that the 5QI parameter of the data stream is different from a default bearer, and the UPF notifies the SMF/PCF to establish a dedicated bearer for the data stream of the specific application, that is, the UPF sends a first message to the SMF/PCF, and the data stream of the subsequent specific application is borne and forwarded through the dedicated bearer, and the scheduling level of the dedicated bearer is higher than that of other bearers, so that the preferential allocation and preemption of bandwidth resources are achieved, and the rate promotion target for the specific application is finally achieved.

After the user stops using the flow of the specific application, the 5G core network element SMF/UPF detects that the flow is finished, reports the flow to the PCF network element, and the PCF network element informs the SMF network element to remove the special bearer of the flow, so that the purposes of occupying the resources for a long time and reasonably utilizing the resources are achieved.

In the above operating environment, the embodiments of the present application provide an embodiment of a data transmission method, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from the order shown.

Fig. 2 is a flowchart of a data transmission method according to an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:

step S202, establishing a special bearer on a core network;

step S204, loading the data stream related to the target address into a special bearer, wherein the resource scheduling priority of the special bearer is higher than that of a default bearer, the target address is the address of a specific service accessed by a target object, and the resource scheduling priority of the default bearer is 5QI =9 by using a 5GQos identifier;

step S206, the data stream is transmitted according to the dedicated bearer.

In the embodiment of the present application, based on the 3GPP protocol framework, in order to implement rate enhancement for a specific application without changing the rate of other services, a flow of the specific application needs to enter a proprietary bearer in a 5G core network, so as to distinguish the flow of the specific application from other flows. And performing corresponding speed increasing action aiming at the special bearer, wherein according to different special bearer establishing types, speed increasing can adopt two methods of special bearer based on Non-GBR and GBR. After the special load is established, the aim of carrying out speed improvement aiming at specific services in a 5G network can be achieved.

The embodiment of the application comprehensively considers the load influence on the operator large network, and realizes the rate increase by adopting a mode that a 5G user uses a specific service to trigger and establish Non-GBR special load. Namely, when a 5G user uses a specific application, a 5G core network is triggered to establish a 5QI =7 high-priority load channel, the flow of the specific application is introduced into the load channel, and meanwhile, a 5G base station side performs priority scheduling on corresponding resources reserved for the load, so that the end-to-end promotion of the specific service uploading/downloading rate under 5G is achieved.

In step S202 of the data transmission method, establishing a dedicated bearer on a core network specifically includes the following steps: acquiring a target address; under the condition that the target address is matched with the address stored in the preset address table, judging whether the target object signs a contract for the target service or not; and under the condition that the target object signs a target service, establishing a special bearer on the core network.

In this embodiment of the present application, if a target address or a target URL address of a current data stream is an address in a preset address table, the data stream has a higher resource scheduling priority, it should be noted that an address with a high resource scheduling priority, for example, a server IP address of a specific application, is stored in a preconfigured address table, the IP address of the specific application is configured in a 5G core network SMF network element, and the dedicated configuration of 5qi =7 is completed in the SMF/PCF.

When the target address is matched with the address stored in the preset address table, it is necessary to determine whether the target object (i.e. the user) sending the data stream signs a target service, and after the user signs a target service, the user can use the dedicated bearer to carry out the bearer or forwarding of the data stream, and at this time, notify the corresponding network element to establish a dedicated bearer in the 5G core network, for example, the UPF notifies the SMF/PCF to establish a dedicated bearer for the data stream of the specific application, and when the user does not sign a target service, the user cannot use the dedicated bearer to carry out the bearer and forwarding of the data stream.

In the above step, after the target address is obtained, the method further includes the following steps: and loading the data stream into the default bearer under the condition that the target address does not match the address stored in the preset address table.

In this embodiment of the present application, if the target address is not in the preset address table, it is determined that the dedicated bearer does not need to be established, and at this time, the data stream needs to be loaded into the default bearer.

In step S202 of the above data transmission method, before establishing the dedicated bearer on the core network, the method further includes the following steps: and determining a preset address table, wherein addresses in the preset address table are transmitted by using a special bearer.

In the embodiment of the present application, the preset address table is set in advance, for example, the address in the preset address table may be a server IP address of a specific application, the IP address of the specific application is configured in a 5G core network SMF network element, a dedicated bearer configuration of 5qi =7 is completed in the SMF/PCF, the resource reservation and a priority scheduling configuration of 5qi =7 are completed in the 5G base station, for example, a priority scheduling ratio of 5qi =6/7/8/9 is set to 4 in advance for 3.

In step S204 of the data transmission method, loading the data stream associated with the target address into a dedicated bearer specifically includes the following steps: acquiring a scheduling priority in a data stream; and loading the data stream into the special bearer under the condition that the scheduling priority in the data stream is the same as the resource scheduling priority of the special bearer.

In this embodiment of the application, if a user uses a specific application under 5G, a value of 5QI carried in a data stream corresponding to the specific application is a preset value, and the value of 5QI represents a scheduling priority of the data stream, for example, a 5QI =7,5g core network UPF network element reports the data stream to a PCF network element after detecting the data stream, and if the 5QI parameter of the data stream detected by the 5G core network is different from a default bearer (corresponding to the 5QI = 9), the UPF notifies the SMF/PCF to establish a dedicated bearer for the data stream of the specific application, that is, the UPF sends a first message to the SMF/PCF, and the data stream of a subsequent specific application is carried and forwarded by the dedicated bearer, and the scheduling level of the dedicated bearer is higher than that of other bearers, thereby achieving preferential allocation and preemption of bandwidth resources, and finally achieving a rate promotion target for the specific application. And when the data stream is transmitted subsequently, loading the data stream into the special bearer under the condition that the scheduling priority in the data stream is judged to be the same as the resource scheduling priority of the special bearer, namely all the data streams are 5QI = 7.

In the above data transmission method, the method further includes the steps of: acquiring target time length, wherein the target time length is used for representing corresponding time length when no data stream exists in the special bearer; and deleting the special bearer under the condition that the target duration is greater than the preset duration.

In the embodiment of the present application, whether to delete the dedicated bearer is determined by using a target duration obtained by a timer, specifically, a preset duration is set in the timer, for example, the preset duration is 10s, when the target duration obtained by the timer exceeds the preset 10s, that is, when there is no data stream in the dedicated bearer, the corresponding duration exceeds 10s, it is determined that the current dedicated bearer needs to be deleted, and the 5G core network element SMF/UPF detects that the stream is finished, and reports the flow to the PCF network element, and the PCF network element notifies the SMF network element to remove the dedicated bearer of the stream, so that the purpose of not occupying the resource for a long time and reasonably utilizing the resource is achieved.

The data transmission method provided by the embodiment of the application can correctly trigger the establishment of the Non-GBR special load of 5QI =7 in the 5G core network, and correctly introduce the flow of the specific application into the special load. As long as the traffic is correctly loaded on the dedicated load, the subsequent base station side performs resource reservation and preferential scheduling on the dedicated load to realize service speed increase. In addition, when the user stops using the specific application flow, the 5G core network automatically deletes the special load, so that resources are prevented from being seized for a long time, and the effects of ensuring according to needs and guaranteeing timely are achieved. Meanwhile, on the premise of not changing the basic charge of the user, the speed increasing function is enabled to each application scene, technical possibility is provided for enriching the application flow value-added service types of the operator, the 5G network use perception of the user is improved, and the service types of the operator are enriched. In addition, the method does not involve construction investment, does not add new equipment, has short landing deployment time and flexible application, and service resources required by speed increase are distributed according to needs, so that new value-added package income can be brought to operators after the speed-increased service resources are realized, and the benefit is extremely high.

The data transmission method can be applied to any 5G application, and can achieve the effect of speeding up aiming at streams of different applications. This is illustrated by the following example:

after the 5G core network deploys the relevant technologies of the embodiment of the application and completes all the configurations, the user signs a target service speed-up service package on the PCF BE of the 5G core network; the subscriber uses the target application, when accessing the server IP address of the configured target service, the end-to-end dedicated load establishment of 5QI =7 is triggered, and meanwhile, the SMF issues the server IP address list to the user terminal, so that the access flow of the addresses can be successfully hit and enter the media plane dedicated load of the SMF-UPF, and other non-target service flow is continuously transmitted in the default load of the user. According to the method, the establishment of the specific flow load for the target application can be successfully realized. Referring to fig. 2-1, it can be seen that QoS Flow of ID =2 establishes exclusive load of 5qi =7, and meanwhile, it is seen that the usage flows are marked with corresponding directional flows, so that the function of intelligent speed increase is satisfied.

The method carries out multiple rounds of test verification in an experimental test environment and a current network formal commercial environment respectively, fig. 2-2 is a schematic diagram of an uplink and downlink acceleration test result of a target application under a 5G network, and as shown in fig. 2-2, the uploading/downloading rate of a 5G target service user guaranteed by the method is remarkably improved, compared with the 5G user who does not use the method for improving the data transmission rate in the embodiment of the application, the uploading/downloading rate of the 5G target service user is improved by about 30%, the guarantee effect is good, and the service use perception is obviously improved.
