With the development of the fifth generation mobile communication technology (5th generation mobile communication technology,5G) age, the number of 5G base stations and the number of 5G mobile users are also rapidly increasing stepwise. The 5G network has wide application in industry, medical treatment, education, traffic and other fields by virtue of the advantages of wide band, low time delay, optical connection, high safety and the like. However, with the rapid development of the 5G network and the rapid increase of the number of 5G users, how to perform refined operation on the network, so as to realize capability output and value change of the 5G network, and optimize network construction investment, and construct a flexible and agile 5G network, which are the problems to be solved by various large operators.

Currently, in 5G networks, operators typically use a framework scheme of dynamic policy and charging control defined by the third generation partnership project (3rd generation partnership project,3GPP) for services that meet user differentiation. The policy control and charging (policy and charging control, PCC) can monitor and reasonably allocate network resources of the user, so that service flow bearing resource guarantee and flow charging policy can be conveniently provided for the user. As shown in fig. 1, a flow chart of PCC-session management (session management, SM) in the related art is shown. The session management function (session management function, SMF) obtains quality of service (quality of service, qoS) information subscribed by the terminal from the unified data management (unified data management, UDM), and the SMF obtains PCC rule information corresponding to the terminal from the policy control function (policy control function, PCF) according to the obtained QoS information. The SMF sends full-direction privacy (perfect forward secrecy, PFS) and QOS information to the user plane function (user plane function, UPF) based on the acquired PCC rule information. Further, the SMF transmits QoS Profile information to the radio access network (radio access network, RAN) through an authentication management function (authentication management function, AMF), and the SMF transmits 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 PFS and QOS information issued by the SMF; the RAN establishes mapping of data radio bearers (data radio bearer, DRB) and QOS flows according to QoS Profile information issued by the SMF; and the terminal executes uplink QOS control according to QOS rules issued by the SMF. However, QOS subscribed in UDM can only allocate 5G quality of service identification (5G QoS identifier,5QI)/address resolution protocol (address resolution protocol, ARP) according to default QOS Flow when a user is online, and provide bandwidth control for the whole APN granularity and bandwidth control for the whole terminal granularity.

In the related art, as shown in the PCC rule issuing schematic diagram in fig. 2, there are three types of PCC rules for the 5G core network. The dynamic PCC RULE is a mode of distributing bandwidth according to user requirements in real time during traffic transmission and dynamically adjusting bandwidth distribution according to network conditions, and the PCF dynamically issues RULE conditions and actions according to terminal subscription information; predefined PCC: the method refers to authorizing the maximum bandwidth resource available to the user through PCC RULEs before call connection is established, and after the terminal signs UP on the PCF, the PCF dynamically issues a User Plane (UP) or RULE name for the terminal according to a trigger point-condition. Further, the SMF or UPF performs QOS control on the terminal session according to the UP or run name issued in advance. The local PCC refers to a bandwidth allocation to a user controlled by the local network through the local PCC when using a local network service. It is deployed in a local network, controls the policies and tariffs of certain border gateways, such as broadband remote access servers (broadband remote access server, BRAS), and allows network operators to formulate different policies according to the needs of users, and the SMF issues UP or run names to the terminals.

However, the bandwidth control granularity of the PCC rule is large, for example, the manner of performing bandwidth control based on the APN is that the overall bandwidth control of all session data flows of the terminal by the APN cannot perform fine bandwidth control for each session data flow of the terminal. Therefore, how to achieve fine control over bandwidth is a technical problem to be solved.

In order to solve the above technical problems, the present application provides a schematic flow diagram of a terminal session data flow control shown in fig. 3. As shown in fig. 3, the SMF obtains information of end user subscription QOS from the UDM. At the same time, the SMF obtains PCC rule information from the PCF. And the SMF sends corresponding policy and charging control information to the UPF according to the acquired QOS information and PCC rule information. Further, when the terminal requests access to the external data network, a session data stream of the terminal is sent to the UPF through the radio network RAN. Correspondingly, when the UPF receives the session data stream of the terminal, the UPF performs refined 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 problems, the present application provides a bandwidth control method, which includes: a bandwidth control device receives a plurality of session data streams for a terminal. The bandwidth control device analyzes the data of the plurality of data streams and determines the data stream type of each session data stream and the priority of each session data stream. The bandwidth control device matches the corresponding bandwidth control rule for each session data stream according to the data stream type and the priority of the session data stream. The bandwidth control device performs bandwidth control on a plurality of session data streams of the terminal according to the bandwidth control rule. In this way, the bandwidth control device determines the data stream type and the priority of each session data stream by carrying out data analysis on a plurality of data streams, and then matches the corresponding bandwidth control rule for each session data stream, thereby realizing the bandwidth control of each session data stream and solving the technical problem of realizing the bandwidth fine control.

The present application provides a broadband control method, which can be applied to a bandwidth control system 40 as shown in fig. 4, where the system 40 includes: a data parsing module 401, a bandwidth control rule matching module 402, and a bandwidth control module 403.

In a possible design, the memory 503 may exist separately from the processor 501, i.e. the memory 503 may be a memory external to the processor 501, where the memory 503 may be connected to the processor 501 through a communication line 502, for storing execution instructions or application codes, and the execution is controlled by the processor 501, to implement a method for determining a spatial measurement according to an embodiment of the present application described below.

Fig. 6 is a schematic diagram of a bandwidth control method according to an embodiment of the present application, as shown in fig. 4, where the bandwidth control method according to the embodiment of the present application may be implemented by the following steps 601 to 604.

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

In one possible implementation, the bandwidth control apparatus receives a plurality of session data streams from the terminal.

In one example, a terminal transmits a plurality of session data flow information to a bandwidth control device via a wireless network, a bearer network. Accordingly, the bandwidth control terminal receives a plurality of session data stream information from the terminal.

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

In one possible implementation manner, the bandwidth control device performs data analysis on the session data stream information from the terminal, where the analysis manner includes, but is not limited to, one or more of the following manners, such as data packet analysis, message identification, and the like. The bandwidth control device determines the priority and the 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 based on the destination IP address in the session data flow resolution data. The data stream types include: a default group+group type and a specific group+user type, wherein the data flow type of the default group+group type refers to that the data flow uses an APN allocated by default to perform a session request, a plurality of user groups are bound under the APN, and the plurality of user groups share a fixed bandwidth resource limit; the data stream type of the specific group+user type is that an APN used by the data stream is a specific APN, each user in the user group bound under the APN is allocated with a specific preset bandwidth resource limit, and the size of the preset bandwidth limit is not influenced by the access of other users.

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

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

In one example, the bandwidth control apparatus determines policy control and charging rules for each session data in turn based on the priority of each session data flow. Further, the bandwidth control device determines a 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 the plurality of session data streams of the terminal based on the target bandwidth control rule.

In a possible implementation manner, the bandwidth control device controls the plurality of session data streams of the terminal according to the target bandwidth control rule determined by the steps above.

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

The scheme at least brings the following beneficial effects: a bandwidth control device receives a plurality of session data streams for a terminal. The bandwidth control device analyzes the data of the plurality of data streams and determines the data stream type of each session data stream and the priority of each session data stream. The bandwidth control device matches the corresponding bandwidth control rule for each session data stream according to the data stream type and the priority of the session data stream. The bandwidth control device performs bandwidth control on a plurality of session data streams of the terminal according to the bandwidth control rule. In this way, the bandwidth control device determines the priority and the data stream type of each session data stream by carrying out data analysis on a plurality of data streams, and then matches the corresponding bandwidth control rule for each session data stream, thereby realizing the bandwidth control of each session data stream and solving the technical problem of realizing the bandwidth fine control.

As shown in fig. 7 in combination with fig. 6. The step 602, that is, the bandwidth control device parses the session data stream to determine the data stream type and priority of the session data stream, may be implemented by the following steps 701 to 703:

in step 701, the bandwidth control device parses each session data flow based on a user plane function UPF, and determines target parsing 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 the UPF through modes such as data packet analysis and message identification, and determines target analysis data including destination IP address information and APN information.

As an example, the target resolution data may further include: port number, URL, protocol data, etc. of the session data stream.

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

In one possible implementation manner, the bandwidth control device determines the priority of the session data stream corresponding to the target IP address according to the target IP address of the session data stream in the target resolution data.

In one example, the bandwidth control apparatus determines that domain names corresponding to the target IP addresses of the plurality of session data flows are A, B, C, D, respectively, according to the target IP addresses in the target resolution data of the plurality of session data flows. The priorities of the domain names are first-level, the priorities of the domain names are second-level, the priorities of the domain names are third-level, and the priorities of the domain names are fourth-level. Then, the priority ordering of the corresponding plurality of session data flows is: 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 resolution data.

In a possible implementation manner, the bandwidth control device determines the type of the APN according to the APN information in the target analysis data. And 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: default APN type and specific APN type.

The scheme at least brings the following beneficial effects: the bandwidth control device analyzes the session data stream based on the user plane function UPF, and determines target analysis data of the session data. And the bandwidth control device respectively determines the priority and the data stream type corresponding to the session data stream according to the IP address information and the APN information in the target analysis data. In this way, the bandwidth control device analyzes the session data streams to accurately determine the priority and the data stream type corresponding to each session data stream. Furthermore, an accurate basis is provided for matching the corresponding bandwidth control rule for each session data stream, and a management basis is provided for realizing bandwidth fine management.

Referring to fig. 6, as shown in fig. 8, the 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 the priority, may be specifically implemented by the following steps 801 to 803:

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

Wherein the first bandwidth control rule is used for controlling the flow of the session data flow and the charging policy.

In one possible implementation, the bandwidth control type rule is of the following types: dynamic policy control and charging PCC, predefined PCC, local PCC. The bandwidth control device matches corresponding bandwidth control type rules for the plurality of session data streams in turn based on priorities of the plurality of session data stream information.

Dynamic PCC refers to a manner in which bandwidth is allocated on demand by users in real time during traffic transmission, and bandwidth allocation is dynamically adjusted according to network conditions, as an example. The method ensures that the current network resources are more flexibly distributed and utilized, and can better adapt to the real-time requirements of different users and application environments; the predefined PCC refers to the maximum bandwidth resources available to the user that are authorized by PCC rules prior to the establishment of the telephony connection. This ensures that the user has sufficient bandwidth resources during the call, avoiding the problem of insufficient bandwidth during the call; the local PCC refers to a bandwidth allocation to a user controlled by the local network through the local PCC when using a local network service. The method is deployed in a local network, controls the strategy and tariff mode of a specific border gateway (such as a BRAS), and allows a network operator to formulate different strategies according to the requirements of users.

It should be noted that the number of the substrates,

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

The second bandwidth control rule is used for controlling the bandwidth allocation mode of the session data stream.

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

In one example, if the priority corresponding to the data stream type is the first priority, the bandwidth control device matches the third bandwidth control rule to the session data stream corresponding to the data type as the target matching bandwidth control rule. The third bandwidth control rule is used for controlling uplink bandwidth and downlink bandwidth of each session data stream respectively. For example, the bandwidth control direction in the session data is controlled, for example, the bandwidth control direction is an uplink direction or a downlink direction; the limit of the uplink bandwidth and the limit of the downlink bandwidth are controlled respectively, and the limit of the uplink bandwidth is M, the limit of the downlink bandwidth is N, and the like.

Optionally, if the priority corresponding to the data stream type is the second priority, the bandwidth control device matches the fourth bandwidth control rule with the session data stream corresponding to the data type as the target matching bandwidth control rule. Wherein the fourth bandwidth control rule is used for performing overall bandwidth control on the plurality of session data streams. For example, a fixed bandwidth limit is allocated for a plurality of session data streams, such as H. When n session data streams simultaneously request access to an application, the bandwidth control means allocates a bandwidth limit of H/n to each of the n session data streams, respectively.

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, that is, a flow charging policy and a bandwidth allocation manner corresponding to each session data flow, based on the first bandwidth control rule and the second bandwidth control rule.

One example, the first bandwidth control rule for session data flow matching is to control traffic and charging policies for session data flows through dynamic PCC; the second bandwidth control rule for session data stream matching is to control the uplink bandwidth and the downlink bandwidth of the session data stream. The target bandwidth control rule for the session data flow is "dynamic PCC + upstream bandwidth and downstream bandwidth control".

The scheme at least brings the following beneficial effects: the bandwidth control device matches corresponding bandwidth control rules for each session data stream information in turn based on priorities of the plurality of session data stream information. The bandwidth control rule is based on the data stream type, and a target bandwidth control rule corresponding to the session data stream under the bandwidth control type rule is matched for each session data stream. In this way, the bandwidth control device first matches the corresponding service logic, i.e. the bandwidth control rule, for each session data flow information in turn according to the priorities of the session data flow information. Further, the bandwidth control device matches the session data stream with a target bandwidth control rule under the bandwidth control rule according to the type of the session data stream. The bandwidth control device determines the target bandwidth control rule of the session data stream step by step according to the priority and the data stream type, improves the accuracy of bandwidth control and realizes the fine management of bandwidth control.
