With the development of the fifth generation mobile communication technology (5th generation mobile communication technology, 5G) era, the number of 5G base stations and the number of 5G mobile users are gradually increasing rapidly. Among them, 5G network has a wide range of applications in many industries such as industry, medical care, education, transportation, etc., by virtue of the advantages of large broadband, low latency, optical connection, and high security. However, with the rapid development of 5G networks and the rapid increase in the number of 5G users, how to conduct refined network operations to realize the output of 5G network capabilities, realize value, optimize network construction investment, and build a flexible and agile 5G network has become an important issue. Major operators urgently need to solve the problem.

Currently, in a 5G network, operators usually use a dynamic policy and charging control framework solution defined by the 3rd Generation Partnership Project (3GPP) to meet user differentiated services. Among them, policy control and charging (policy and charging control, PCC) can monitor and rationally allocate network resources of users, so as to provide users with service flow bearer resource guarantee and flow charging policies. As shown in FIG. 1 , it is a schematic flow chart of PCC-session management (session management, SM) in the related art. Among them, the session management function (session management function, SMF) obtains the quality of service (quality of service, QoS) information signed by the terminal from the unified data management (unified data management, UDM), and the SMF obtains the QOS information from the policy control function (policy control function (PCF) to obtain the PCC rule information corresponding to the terminal. The SMF sends perfect forward secrecy (PFS) and QOS information to a user plane function (user plane function, UPF) according to the acquired PCC rule information. Further, the SMF sends QoS Profile information to the radio access network (radio access network, RAN) through an authentication management function (authentication management function, AMF), and the SMF sends QOS rules to the terminal through the AMF. Correspondingly, the UPF performs uplink QOS flow identifier (qos flow identifier, QFI) verification and downlink QFI marking and control according to the PFS and QOS information issued by the SMF; the RAN establishes a data radio bearer according to the QoS Profile information issued by the SMF ( data radio bearer (DRB) and QOS flow mapping; the terminal performs uplink QOS control according to the QOS rules issued by the SMF. However, the QOS signed in UDM can only allocate 5G service quality identifier (5G QoS identifier, 5QI)/address resolution protocol (address resolution protocol, ARP) according to the default QoS Flow when the user goes online, and provide the terminal with the entire APN granularity Bandwidth control and bandwidth control at the granularity of the entire terminal.

In related technologies, in the schematic diagram of issuing PCC rules as shown in Figure 2, there are three types of PCC rules for the 5G core network. Among them, the dynamic PCC rule refers to the method of allocating bandwidth according to user needs in real time during traffic transmission, and dynamically adjusting bandwidth allocation according to network conditions. PCF dynamically issues RULE conditions and actions according to terminal subscription information; predefined PCC: refers to It is the maximum available bandwidth resource authorized by the PCC rule before the call connection is established. After the terminal signs up on the PCF, the PCF dynamically issues the user plane (user plane, UP) or RULE name to the terminal according to the "trigger point-condition". Further, the SMF or UPF performs QOS control on the terminal session according to the pre-delivered UP or RULE name. The local PCC means that when using the local network service, the local network controls bandwidth allocation to users through the local PCC. It is deployed in the local network and controls the policy and charging mode of specific border gateways, such as broadband remote access server (BRAS), and allows network operators to formulate different policies according to user needs. The terminal issues the UP or RULE name.

However, the bandwidth control granularity of PCC rules is large. For example, the way of bandwidth control based on APN is to control the overall bandwidth of all session data streams of the terminal through APN, and it is impossible to refine the bandwidth of each session data stream of the terminal. control. Therefore, how to realize fine-grained control of bandwidth has become an urgent technical problem to be solved.

In order to solve the above technical problem, the present application provides a schematic diagram of a terminal session data flow control flow as shown in FIG. 3 . As shown in Figure 3, the SMF obtains the information of the terminal user's QOS subscription from the UDM. At the same time, the SMF obtains the PCC rule information from the PCF. SMF sends corresponding policy and charging control information to UPF according to the obtained QOS information and PCC rule information. Further, when the terminal requests to access the external data network, the session data flow of the terminal is sent to the UPF through the wireless network RAN. Correspondingly, when the UPF receives the session data stream of the terminal, it performs fine-grained bandwidth control on the session data stream according to the policy and charging control information issued by the SMF.

In order to solve the above technical problem, the present application provides a bandwidth control method, which includes: a bandwidth control device receives multiple session data streams of a terminal. The bandwidth control device performs data analysis on multiple data streams to determine the data stream type of each session data stream and the priority of each session data stream. The bandwidth control device matches a corresponding bandwidth control rule for each session data flow according to the data flow type and priority of the session data flow. The bandwidth control device performs bandwidth control on multiple session data streams of the terminal according to the bandwidth control rule. In this way, the bandwidth control device determines the data flow type and priority of each session data flow by analyzing the data of multiple data flows, and then matches the corresponding bandwidth control rules for each session data flow, realizing the control of each session The bandwidth control of the data stream solves the technical problem of realizing fine bandwidth control.

FIG. 6 shows the bandwidth control method provided by the embodiment of the present application. As shown in FIG. 4 , the bandwidth control method provided by the embodiment of the present application can be implemented through the following steps 601 to 604.

Step 601, the bandwidth control apparatus receives multiple session data streams from a terminal.

In a possible implementation manner, the bandwidth control device receives multiple session data streams from the terminal.

In one example, the terminal sends multiple session data flow information to the bandwidth control device through a wireless network or a bearer network. Correspondingly, the bandwidth control terminal receives multiple sessions of data flow information from the terminal.

Step 602, the bandwidth control device analyzes each session data flow, and determines the priority and data flow type of each session data flow.

In a possible implementation, the bandwidth control device performs data analysis on multiple session data flow information from the terminal, and the analysis methods include but are not limited to one or more of the following methods, such as data packet analysis, message identification wait. The bandwidth control device determines the priority and data flow type of each session data flow according to the message identification result.

In one example, the priority of the session data flow may be determined according to the destination IP address in the analysis data of the session data flow. Data flow types include: "default group + group type" and "specific group + user type", where the data flow type of "default group + group type" means that the data flow uses the default assigned APN A session request is made, and multiple user groups are bound under the APN, and multiple user groups share a fixed bandwidth resource limit; the data flow type of "specific group + user type" refers to the APN used by the data flow For a specific APN, each user in the user group bound under the APN is assigned a specific preset bandwidth resource limit, and the size of the preset bandwidth resource limit is not affected by other users' access.

Step 603, the bandwidth control device determines a target bandwidth control rule corresponding to each session data flow based on the data flow type and priority.

In a possible implementation manner, the bandwidth control device matches each session data flow with its corresponding bandwidth control rule according to the priority and data flow type of each session data flow.

In one example, the bandwidth control device sequentially determines policy control and charging rules for each session data based on the priority of each session data flow. Further, the bandwidth control device determines the target bandwidth control rule of the session data flow under the corresponding policy control and charging rules based on the data flow type.

Step 604, the bandwidth control device performs bandwidth control on multiple session data streams of the terminal based on the target bandwidth control rule.

In a possible implementation manner, the bandwidth control device controls the multiple session data flows of the terminal respectively according to the corresponding target bandwidth control rules according to the target bandwidth control rules determined in the above steps.

In one example, the target bandwidth control rule is to separately perform bandwidth control on each session data flow among the plurality of session data flows, and assign a separate preset bandwidth resource limit to each session data flow. Optionally, the target bandwidth control rule is to perform overall bandwidth control on multiple session data streams, and assign an overall preset bandwidth resource limit to multiple session data streams.

The above solution brings at least the following beneficial effects: the device for bandwidth control receives multiple session data streams of the terminal. The bandwidth control device performs data analysis on multiple data streams to determine the data stream type of each session data stream and the priority of each session data stream. The bandwidth control device matches a corresponding bandwidth control rule for each session data flow according to the data flow type and priority of the session data flow. The bandwidth control device performs bandwidth control on multiple session data streams of the terminal according to the bandwidth control rule. In this way, the bandwidth control device determines the priority and data flow type of each session data flow by performing data analysis on multiple data flows, and then matches the corresponding bandwidth control rules for each session data flow, realizing the control of each session The bandwidth control of the data stream solves the technical problem of realizing fine bandwidth control.

Combined with Figure 6, it is shown in Figure 7. The above step 602, that is, the bandwidth control device analyzes the session data stream to determine the data stream type and priority of the session data stream, which can also be specifically implemented through the following steps 701-703:

Step 701, the bandwidth control device analyzes each session data flow based on a user plane function UPF, and determines target analysis data of each session data flow.

In a possible implementation manner, the bandwidth control device performs data analysis on the session data stream based on UPF by means of data packet analysis and message identification, and determines target analysis data including destination IP address information and APN information.

As an example, the target parsing data may also include: port number, URL, protocol data and other information of the session data stream.

Step 702, the bandwidth control device determines the priority of each session data flow based on the destination IP address information in the destination analysis data.

In a possible implementation manner, the bandwidth control device determines the priority of the session data flow corresponding to the target IP address according to the target IP address of the session data flow in the target analysis data.

In one example, the bandwidth control device determines the domain names corresponding to the target IP addresses of the multiple session data streams as A, B, C, and D according to the target IP addresses in the target analysis data of the multiple session data streams. Among them, the priority of D domain name is first level, the priority of B domain name is second level, the priority of A domain name is third level, and the priority of C domain name is fourth level. Then, the priorities of the corresponding multiple session data streams are: D, B, A, C.

Step 703, the bandwidth control device determines the data flow type of each session data flow based on the APN information in the target analysis data.

In a possible implementation manner, the bandwidth control device determines the type of the APN according to the APN information in the target parsing data. The bandwidth control device determines the data flow type of the session data flow according to the type corresponding to the APN.

An example, the type of APN includes: a default APN type and a specific APN type.

The above solution brings at least the following beneficial effects: the bandwidth control device analyzes the session data flow based on the user plane function UPF, and determines the target analysis data of the session data. The bandwidth control device respectively determines the priority and data flow type corresponding to the session data flow according to the IP address information and APN information in the target analysis data. In this way, the bandwidth control device accurately determines the priority and data flow type corresponding to each session data flow by analyzing the session data flow. Furthermore, it provides accurate basis for matching the corresponding bandwidth control rules of each session data flow, and provides a management basis for realizing fine bandwidth management.

In conjunction with FIG. 6, as shown in FIG. 8, the above step 603, that is, the bandwidth control device matches the bandwidth control rule corresponding to the session data flow based on the data flow type and priority, which can be specifically implemented through the following steps 801 to 803:

Step 801, the bandwidth control device matches the first bandwidth control rule corresponding to each session data flow based on the priority of each session data flow.

Wherein, the first bandwidth control rule is used to control the flow rate and charging policy of the session data flow.

In a possible implementation manner, the bandwidth control type rules include the following types: dynamic policy control and charging PCC, predefined PCC, and local PCC. The bandwidth control device sequentially matches the corresponding bandwidth control type rules for the multiple session data streams based on the priorities of the multiple session data stream information.

As an example, dynamic PCC refers to a method of allocating bandwidth according to user requirements in real time during traffic transmission and dynamically adjusting bandwidth allocation according to network conditions. It enables the current network resources to be allocated and utilized more flexibly, and can better adapt to the real-time needs of different users and application environments; the predefined PCC refers to the maximum available bandwidth resource authorized by the user through the PCC rule before the call connection is established . This can ensure that the user has sufficient bandwidth resources during the call, avoiding the problem of insufficient bandwidth during the call; the local PCC means that when using the local network service, the local network controls the bandwidth allocation to the user through the local PCC. It is deployed in the local network, controls the policies and charging methods of specific border gateways (such as BRAS), and allows network operators to formulate different policies according to user needs.

It should be noted,

Step 802, the bandwidth control device matches the second bandwidth control rule corresponding to each session data flow based on the data flow type of each session data flow.

Wherein, the second bandwidth control rule is used to control the bandwidth allocation manner of the session data flow.

In a possible implementation manner, the bandwidth control device determines the priority corresponding to the data flow type according to the data flow type. The bandwidth control device matches the session data flow with the target bandwidth control rule under the corresponding bandwidth control type rule based on the priority of the data flow type.

In one example, if the priority corresponding to the data flow type is the first priority, the bandwidth control device matches the third bandwidth control rule to the session data flow corresponding to the data type as the target matching bandwidth control rule. Wherein, the third bandwidth control rule is used to respectively control the uplink bandwidth and downlink bandwidth of each session data flow. For example, control the bandwidth control direction in the session data, such as the bandwidth control direction is the uplink direction or the downlink direction; respectively control the uplink bandwidth limit and the downlink limit, such as the uplink bandwidth limit is M, the downlink bandwidth limit is N, etc.

Optionally, if the priority corresponding to the data flow type is the second priority, the bandwidth control device matches the fourth bandwidth control rule to the session data flow corresponding to the data type as the target matching bandwidth control rule. Wherein, the fourth bandwidth control rule is used to perform overall bandwidth control on multiple session data flows. For example, a fixed bandwidth limit is assigned to multiple session data streams, for example, the fixed bandwidth limit is H. When there are n session data streams requesting to access the application at the same time, the bandwidth control device allocates a bandwidth limit of H÷n to each session data stream in the n session data streams.

Step 803, the bandwidth control device determines a target bandwidth control rule corresponding to each session data flow based on the first bandwidth control rule and the second bandwidth control rule.

In a possible implementation manner, the bandwidth control device generates a target bandwidth control rule corresponding to each session data flow based on the first bandwidth control rule and the second bandwidth control rule, that is, the traffic charging policy and the traffic charging policy corresponding to each session data flow. Bandwidth allocation method.

An example, the first bandwidth control rule matched by the session data flow is to control the flow and charging policy of the session data flow through dynamic PCC; the second bandwidth control rule matched by the session data flow is the uplink bandwidth and downlink bandwidth of the session data flow Bandwidth is controlled. Then the target bandwidth control rule of the session data flow is "dynamic PCC+uplink bandwidth and downlink bandwidth control".

The above solution brings at least the following beneficial effects: the bandwidth control device sequentially matches the corresponding bandwidth control rules for each session data flow information based on the priorities of the plurality of session data flow information. The bandwidth control rule is based on the data flow type, and matches the target bandwidth control rule corresponding to the session data flow under the bandwidth control type rule for each session data flow. In this way, the bandwidth control device first matches the corresponding service logic, that is, the bandwidth control rule, for each session data flow information sequentially according to the priorities of the plurality of session data flow information. Further, the bandwidth control device matches the session data flow with the target bandwidth control rule under the bandwidth control rule according to the type of the session data flow. The bandwidth control device determines the target bandwidth control rule of the session data flow step by step according to the priority and the data flow type, which improves the accuracy of the bandwidth control and realizes the refined management of the bandwidth control.
