[0043] In order to enable a more detailed understanding of the features and technical contents of the embodiments of the present invention, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the embodiments of the present invention.

[0044] See also Figure 1 , which shows a basic network architecture with multi-access 5G, which can be called a service-based network architecture (SBA). Figure 1As shown, the user equipment (UE) accesses the core access and mobility management function (AMF) through the (radio) access network ((R)AN, (Radio) Access Network), and the UE can also directly access the AMF; AMF is used to process the control plane messages of the network, and its function is similar to the EPS mobility management (EMM) in the mobile management entity (MME, Mobility Management Entity) in the long-term evolution (LTE, Long Term Evolution) system. The authentication service function (AUSF, Authentication Server Function) is similar to the sound function of the MME in the LTE system, realizing two-way authentication of the UE and supporting a unified authentication framework. The user plane function (UPF, Userplane Function) is similar to the combination of the service gateway S-GW and the PDN gateway P-GW in the LTE system, and is connected to the data network DataNetwork. The session management function (SMF, Session Management Function) is similar to the EPS session management ESM function in the LTE system, and is mainly used to manage, establish, modify and release sessions. It can be seen that the function set of AUSF, AMF and SMF is similar to the MME in the LTE system. In addition, Figure 1 The structure shown also includes: Network Exposure Function (NEF), Network Element Repository Function (NRF), Policy Control Function (PCF), Unified Data Management (UDM) and Application Function (AF); wherein, NEF is used to display some capabilities of network functions to the outside, such as monitoring capability, supply capability, and policy or billing capability; NRF can support service discovery function; PCF supports a unified policy framework for managing network behavior; UDM includes an application front end (FE) and a user data repository (UDR), FE can access the subscription user information in UDR, the function of UDM is similar to HSS in LTE system, UDR provides subscription data storage service, and application front end FE provides data-based application logic; AF is used to provide application services.

[0045] It can be seen from the network in the above architecture that the architecture between the (wireless) access network (R)AN and the data network DataNework can be called the 5G core network, and the network elements in the 5G core network are called 5G core network network elements. In 5G technology, terminals are allowed to achieve multi-connection data transmission through communication links of multiple access networks. Multiple access networks can include access networks that use 5G NR access technology (NR, New Radio), LTE access, and other access networks that comply with 3GPP standards, and can also include non-3GPP standard access networks, such as wireless fidelity (WIFI, WIreless-FIdelity) networks, etc. This embodiment will not be described in detail.

[0046] In order to control the data flow of multi-connection data transmission in a 5G network, the embodiment of the present invention is based on Figure 1 In the network architecture shown, an additional service access management node (ATSSS / AT3SF) is set to control the data stream to be transmitted for multi-connection transmission. When the data stream to be transmitted is a downlink data stream, the service access management node can be set as an independent network element entity between the (R)AN and the 5G core network network element; it can also be distributed in the network elements of the 5G core network that have data transmission requirements with the UE, such as UDM, SMF, PCF and UPF. This embodiment does not go into details. When the data stream to be transmitted is an uplink data stream, the service access management node is set as an independent network element entity between the (R)AN and the UE, and can also be implemented as a function of the UE. This embodiment does not go into details.

[0047] In an embodiment of the present invention, the service access management node ATSSS receives an access network status report reported by an access device that provides an access network communication link, and determines the data distribution amount of the data stream to be transmitted in each access device based on the received access network status report, thereby performing multi-connection data transmission control for the data stream to be transmitted to improve the throughput of service data.

[0048] Based on the above contents, the following embodiments are proposed.

[0049] Embodiment 1

[0050] See also Figure 2 , which shows a data distribution method provided by an embodiment of the present invention, the method is applied to a service access management node, and the method includes:

[0051] S201: receiving an access status report sent by at least one access device; wherein the access status report includes a plurality of network status information for characterizing an access network provided by a corresponding access device;

[0052] S202: Determine the data distribution volume corresponding to each access device based on the network status information of the access network provided by each access device and the data stream to be transmitted.

[0053] It should be noted that no matter whether the data stream to be transmitted is an uplink data stream or a downlink data stream, the service access management node can receive an access status report from the access device, and thereby determine the data distribution volume corresponding to each access device based on the access status report.

[0054] It can be understood that the access network provided by multiple access devices that provide multiple connections may include access networks of 3GPP protocols and access networks of non-3GPP protocols, such as access networks provided by 5G base stations gNB and WIFI access points; it may also include access networks of different radio access technologies RAT in the 3GPP protocol, such as access networks provided by 5G base stations gNB and LTE evolved base stations (eNB, evolved Node B).

[0055] pass Figure 2 In the technical solution shown, the service access management node obtains the network status information of the access network provided by each access device through the access status report, and determines the data distribution amount corresponding to each access device based on the network status information, thereby performing multi-connection data transmission control for the data stream to be transmitted to improve the throughput of service data.

[0056] for Figure 2 In the technical solution shown, in a possible implementation, when the access network provided by the access device is an access network that is not a 3GPP protocol access network, the access status report includes at least one or more of the following network status information: basic service set BSS load information, wide area network metric WAN Metrics information, utilization of available channels, amount of data to be transmitted, and number of users who have accessed. It can be understood that the above items can all represent the network status information of non-3GPP access networks. In addition to the above items, other network status information that can represent non-3GPP access networks can also be included in the access status report, which is not described in detail in this embodiment.

[0057] for Figure 2In the technical solution shown, in a possible implementation, when the access network provided by the access device is an access network of the Third Generation Partnership Project 3GPP protocol, the access status report includes at least one or more of the following network status information: load information of the access network, the number of access users of the access network, the amount of data to be transmitted currently cached by the access network, the current resource utilization rate of the access network, the user throughput of the access network within a preset time period, and the data packet information that was not correctly sent by the access network. It can be understood that the above items can all represent the network status information of the 3GPP access network. In addition to the above items, other network status information that can represent the 3GPP access network can also be included in the access status report, which is not described in detail in this embodiment.

[0058] For the above possible implementation, the data packet information that is not correctly sent by the access network includes at least one of the following:

[0059] The sequence number of the data packet that has been transmitted but not successfully transmitted by the access network;

[0060] The minimum sequence number of the data packet to be transmitted by the access network;

[0061] The proportion of data packets transmitted erroneously by the access network within a preset time period.

[0062] for Figure 2 In the technical solution shown, in a possible implementation manner, the access status report can be obtained by requesting the service access management node. Therefore, before receiving the access status report sent by at least one access device, the method further includes:

[0063] Sending request information for the access status report to the at least one access device.

[0064] for Figure 2 In the technical solution shown, in a possible implementation manner, the access status report may be periodically reported by the access device, and therefore, the receiving of the access status report sent by at least one access device includes:

[0065] An access status report sent by the at least one access device is received at a preset periodic interval.

[0066] for Figure 2 In the technical solution shown, in a possible implementation manner, the access status report can be reported by the access device in the form of event triggering. Therefore, the receiving of the access status report sent by at least one access device includes:

[0067] An access status report sent by the at least one access device based on a preset triggering event is received.

[0068] for Figure 2 The technical solution shown, in a possible implementation, when it is necessary to distribute data to the data stream to be transmitted, the data distribution amount corresponding to each access device should be determined by the network status information of the access network provided by each access device. If the network status information can indicate that the network status of the access network is better, most of the data stream to be transmitted can be distributed to the access network with better network status; if the network status information can indicate that the network status of the access network is not good, a small part of the data stream to be transmitted can be distributed to the access network with poor network status. Therefore, see Figure 3 , based on the network status information of the access network provided by each access device and the data stream to be transmitted, determining the data distribution amount corresponding to each access device, including:

[0069] S2021: Allocate corresponding weights to the network status information of the access network provided by each access device according to a set weight allocation strategy;

[0070] S2022: Obtaining a data distribution calculation value corresponding to the access network provided by each access device according to the network status information of the access network provided by each access device and the corresponding weight;

[0071] S2023: Divide the data stream to be transmitted according to the data distribution calculation value corresponding to the access network provided by each access device, and determine the data distribution amount corresponding to each access device.

[0072] Specifically, for the access status reports of the above two types of access networks, each access status report includes at least one type of network status information. Therefore, when it is necessary to characterize the network status of the access network through the network status information in the access status report, a corresponding weight can be assigned to each network status information item included in the access status report, and then the content of each network status information item is multiplied by the corresponding weight and summed up. The network status of the access network can be scored. The obtained score is the data distribution calculation value, which can be used to characterize whether the network status of the access network is good.

[0073] Through the above scheme, the service access management node obtains the network status information of the access network provided by each access device by receiving the access network status report sent by each access device, and divides the data flow to be transmitted according to the network status information of each access network, and determines the data distribution amount corresponding to each access device, so as to perform multi-connection data transmission control for the data flow to be transmitted, so as to improve the throughput of service data.

[0074] Embodiment 2

[0075] Based on the same inventive concept as the above embodiments, see Figure 4, which shows a data distribution method provided by an embodiment of the present invention, the method is applied to an access device, and the method includes:

[0076] S401: Sending an access status report of the access network provided by the access device itself to a service access management node;

[0077] The access status report includes a plurality of network status information for characterizing the access network provided by the access device itself, and is also used by the service access management node to determine the data distribution volume corresponding to the access device according to the data flow to be transmitted.

[0078] for Figure 4 In the technical solution shown, in one possible implementation, when the access network provided by the access device is an access network that is not a Third Generation Partnership Project 3GPP protocol, the access status report includes at least one or more of the following network status information: basic service set BSS load information, wide area network WAN Metrics information, utilization of available channels, amount of data to be transmitted, and number of users who have accessed.

[0079] for Figure 4 The technical solution shown, in one possible implementation, when the access network provided by the access device is an access network of the Third Generation Partnership Project 3GPP protocol, the access status report includes at least one or more of the following network status information: load information of the access network, the number of access users of the access network, the amount of data to be transmitted currently cached in the access network, the current resource utilization of the access network, the user throughput of the access network within a preset time period, and information on data packets that were not correctly sent by the access network.

[0080] In the above implementation, the data packet information that is not correctly sent by the access network includes at least one of the following:

[0081] The sequence number of the data packet that has been transmitted but not successfully transmitted by the access network;

[0082] The minimum sequence number of the data packet to be transmitted by the access network;

[0083] The proportion of data packets transmitted erroneously by the access network within a preset time period.

[0084] for Figure 4 In the technical solution shown, in a possible implementation manner, the access status report can be obtained by request through the service access management node. Therefore, before sending the access status report of the access network provided by the access device itself to the service access management node, the method also includes:

[0085] Receive request information for the access status report sent by the service access management node.

[0086] for Figure 4 In the technical solution shown, in a possible implementation manner, the access status report can be reported periodically, therefore, sending the access status report of the access network provided by the access device itself to the service access management node includes:

[0087] An access status report of the access network provided by the access device itself is sent to the service access management node at preset periodic intervals.

[0088] for Figure 4 In the technical solution shown, in a possible implementation manner, the access status report can be reported in the form of event triggering. Therefore, the sending of the access status report of the access network provided by the access device itself to the service access management node includes:

[0089] An access status report of the access network provided by the access device itself is sent to the service access management node based on a preset trigger event.

[0090] In the above implementation, specifically, the sending of the access status report of the access network provided by the access device itself to the service access management node based on a preset trigger event includes:

[0091] When the network status information represented in the access status report and the preconfigured threshold value meet the set judgment condition, sending the access status report of the access network provided by the access device itself to the service access management node; or,

[0092] When the network status information represented in the access status report and the preconfigured threshold value meet the set judgment condition, sending the access status report of the access network provided by the access device itself to the service access management node at a set periodic interval until the judgment condition is not met; or,

[0093] When the network status information represented in the access status report and the preconfigured threshold value meet the set judgment condition, the access status report of the access network provided by the access device itself is sent to the service access management node at a set periodic interval until the set timing time period times out; or,

[0094] When the network status information represented in the access status report and the preconfigured threshold value meet the set judgment condition, the access status report of the access network provided by the access device itself is sent to the service access management node according to a predefined number of sending times.

[0095] In the data distribution method provided in this embodiment, the access device sends an access status report to the service access management node, so that the service access management node learns the network status of the access network through the access status report, and distributes the data stream to be transmitted according to the network status of the access network. Multi-connection data transmission control is implemented for the data stream to be transmitted, thereby improving the throughput of service data.

[0096] Embodiment 3

[0097] Based on the same inventive concept as the previous embodiment, this embodiment illustrates the technical solution of the previous embodiment through specific examples. In this specific example, the service access management node AT3SF can be distributed in the network elements with data transmission requirements in the 5G core network, such as UDM, SMF, PCF, SMF and UPF; it is also set in the UE, see Figure 5 The architecture diagram shown in Figure 5 In the UE, the access device includes not only 3GPP protocol access devices 3GPP Access, such as gNB or eNB, but also non-3GPP access devices Non-3GPP Access, such as WIFI access points. Figure 5 The architecture shown in the figure can distribute and control the uplink data stream to be transmitted or the downlink data stream to be transmitted according to the solutions of the above two embodiments. The technical solution of the embodiment of the present invention involves a service access management node and an access device. Figure 5 In the architecture, the part of the architecture that is of interest should be as follows Figure 6 As shown, ATSSSFunction represents the service access management node, UP Function is the user plane network device of the core network, TrustedWLAN can be a WIFI access point, which represents the access device of the non-3GPP access network, and NextGenRAN can be a gNB, which represents the access device of the 3GPP access network. When transmitting data for the service, UE or ATSSSFunction can separate the data stream to be transmitted in the non-3GPP access network and the 3GPP access network for simultaneous transmission to improve the throughput of the service. Specifically in the network protocol stack, the data transmission process is as follows: Figure 7 As shown, both the core network side and the UE have communication links of multiple access networks. The core network side or the UE needs to separate the data streams to be transmitted in the communication links of each access network for transmission. Therefore, the service access management node needs to determine the data distribution amount for the data streams to be transmitted through the access status reports reported by each access device according to the scheme of the aforementioned embodiment.

[0098] by Figure 7As an example of the transmission process shown in the figure, the application APP-1 in the UE needs to transmit data to the network side. The service access management node can be arranged in the form of client / server C / S between the UE and the access network and the core network. Figure 7 For example, the UE is an ATSSS client Client, the ASSSS Function between the access network and the core network is an ASSSS server Server, and a control connection channel ControlConnection is set between the ATSSS Client and the ATSSS Server, so that control information for multi-connection data transmission can be transmitted between the two. The service management node can receive access status reports sent by the first access device providing RAN and the second access device providing WLAN. The access status report includes multiple network status information for characterizing the access network. The service management node divides the transmission data flow according to the quality of the network status represented by the network status information of each access network, and determines the data distribution amount corresponding to each access device, that is, determines the data distribution amount of the communication link of each access network. The specific determination process is as shown in Example 1. Figure 3 No matter which party ATSSS Client or ATSSS Server determines to complete the data distribution amount of the communication link of each access network, it can inform the other party through Control Connection, so that the other party distributes the data stream to be transmitted according to the data distribution amount.

[0117] The data stream to be transmitted is divided according to the data distribution calculation value corresponding to the access network provided by each access device, and the data distribution amount corresponding to each access device is determined.

[0119] In addition, each component in this embodiment may be integrated into one processing unit, or each unit may exist physically separately, or two or more units may be integrated into one unit. The above integrated unit may be implemented in the form of hardware or in the form of software function modules.

[0120] If the integrated unit is implemented in the form of a software function module and is not sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this embodiment is essentially or the part that contributes to the prior art or the whole or part of the technical solution can be embodied in the form of a software product. The computer software product is stored in a storage medium, including several instructions for a computer device (which can be a personal computer, server, or network device, etc.) or a processor to perform all or part of the steps of the method described in this embodiment.
