The dynamic control method and the terminal of the QoS flow are suitable for dynamically adjusting the QoS flow according to the service type of the terminal user, and can improve the utilization rate of bandwidth resources, and the method and the terminal are described by the following specific embodiments:
example 1
Referring to fig. 1, 3 and 4, a dynamic control method for QoS flows includes the steps of:
s1, setting a service blacklist and a service whitelist based on user information.
And setting a service blacklist and/or a service whitelist based on the user information and the application program, and placing the service blacklist and the service whitelist in a unified data management module.
Specifically, referring to fig. 3, a service black-and-white list is configured based on user information and a name of an application, for example: QQ, weChat, microblog, etc., the configuration information is placed in a UDM (Unified Data Management ) module.
And periodically caching the IP addresses of the application programs in the service blacklist and the service whitelist to a strategy control function network element.
Specifically, IP address information corresponding to the application program is provided by a DPI (Deep Packet Inspection ) server, and the PCF (Policy Control Function, policy control function) periodically acquires an IP address node table and caches the IP address node table in a database of the PCF.
S2, acquiring a session establishment request of a user, if the user is provided with a service white list, establishing a white list QoS flow, when the white list QoS flow receives the white list service data message, increasing the priority of the white list QoS flow, and when the white list QoS flow stops receiving the white list service data message, reducing the priority of the white list QoS flow.
Wherein, after the session establishment request of the user is obtained, the method comprises the following steps:
and acquiring a corresponding service blacklist and a corresponding service whitelist from the unified data management module according to the user information.
Specifically, referring to fig. 4, an smf (Session Management Function ) network element obtains black and white list information from a UDM network element through an SBI interface HTTP2 protocol; after receiving the acquisition request, the UDM network element reads the configuration of the local database black-and-white list.
Wherein if the user is provided with a service white list, the method further comprises:
and requesting policy control rules from the policy control function network element, configuring configuration information of a service white list to the policy control function network element, and binding the configuration information and the IP address of the application program with corresponding users one by one.
Specifically, if the SMF network element is configured with a white list, the SMF network element requests PCC (policy control and charging) rules from the PCF network element through an SBI interface HTTP2 protocol, a QoS service configuration template corresponding to the white list is preconfigured in the PCF network element, the PCF obtains IP address information in the DPI and performs one-to-one binding with the 5G user, and when the user is online, the user can enjoy the service of the customized network.
And establishing a white list QoS flow and a default QoS flow, when the white list service starts, increasing the priority of the white list QoS flow, and when the white list service stops or terminates, reducing the priority of the white list QoS flow.
S3, if the user is provided with a service blacklist, establishing a blacklist QoS flow, and discarding the blacklist service data message when the blacklist QoS flow receives the blacklist service data message.
If the user is provided with a service blacklist, a policy control rule is requested to the policy control function network element, configuration information of the service blacklist is configured to the policy control function network element, and the configuration information is bound with the corresponding user one by one;
and discarding the blacklist service data message when the blacklist service starts.
Specifically, if a blacklist is configured, the SMF network element requests PCC rules from the PCF network element through an HTTP2 protocol of an SBI interface, a QoS service configuration template corresponding to the blacklist is preconfigured on the PCF network element and is bound with 5G users one to one, and when the users are online, the service of the customized network can be enjoyed; and establishing a blacklist QoS flow, wherein the blacklist QoS flow is used for blacklist service and is a Non-GBR (Non-Guaranteed Bit Rate ) flow, and the UPF side forwarding rule is discard.
Therefore, if only blacklist traffic is configured, two QoS flows need to be established: default QoS flows and blacklisted QoS flows; if only white list service is configured, two QoS flows need to be established: default QoS flows and whitelist QoS flows; if the user is configured with both blacklist and whitelist services, three QoS flows need to be established: default QoS flows, blacklisted QoS flows, and whitelisted QoS flows.
Referring to fig. 3, when the SMF determines to use the QoS control mechanism, the SMF sends QoS control information including a service data flow (Service Data Flow, SDF) to the UPF, sends QoS profile to AN (Access Network layer) and sends corresponding QoS rules to a UE (User Equipment). The UPF executes QoS control of the downlink Data packet and QoS verification of the uplink Data packet according to the QoS control information of the SDF, and forwards the Data packet to a DN (Data Network layer); the AN establishes a DRB (Data Radio Bearers, data bearing) or a binding relation between the DRB and the QoS flow according to the QoS profile, and further performs transmission control of the data packet; the UE performs transmission control of the uplink data packet according to the QoS rule.
Therefore, the embodiment can realize the access of the user of the Ethernet interface to the AC (controller) without changing the QoS networking architecture in the original 5G customized network, and realize the management of the AC to the user of the Ethernet interface and the forwarding of data messages. Under the condition of meeting the actual application scene, the method has higher realizability and usability.
Example two
Referring to fig. 3 and fig. 4, the difference between the present embodiment and the first embodiment is that how to modify the priority of QoS flows is further defined, specifically:
establishing a white list QoS flow, initializing the white list QoS flow into a non-guarantee flow, acquiring configuration information of a service white list from the strategy control function network element when white list service starts, performing service processing according to the configuration information in the white list, and improving the white list QoS flow into a guarantee flow;
and when the white list service is ended or stopped, reducing the white list QoS flow to a non-guaranteed flow.
In this embodiment, two QoS flows are established: default QoS flows and whitelist QoS flows, where the whitelist QoS flows are used for processing whitelist services, the whitelist QoS flows are initially Non-GBR flows, forwarding rules are forwarding, and URR (Usage Reporting Rules, report rule is used) is started for the whitelist QoS flows to report, reporting types are event, and detection conditions are as follows: the Start Traffic or Stop Traffic is detected.
The UPF network element detects whether the URR ID has a sent data packet, and reports a PFCP (Packet Forwarding Control Protocol, message forwarding control protocol) Session Report message carrying a Start Traffic flag to the SMF network element once the UPR ID receives the uplink or downlink data packet;
the SMF network element obtains GBR (Guaranteed Bit Rate ) QoS flow from the PCF network element through an SBI interface HTTP2 protocol, obtains a special QoS configuration template preset for an application program, and after receiving a detection report of the UPF network element, the SMF network element sends configuration for improving the priority and related bandwidth of the white list QoS flow to the UPF network element so as to improve the white list QoS flow into a guaranteed flow.
Wherein when the SMF determines to use the QoS control mechanism, the SMF sends QoS control information including the service data flow (Service Data Flow, SDF) to the UPF, and the AMF (Access and Mobility Management Function ) sends QoS profile to the AN and corresponding QoS rules to the UE.
After the UPF network element detects that the UE does not send APP data, PFCP Session Report information carrying a Stop Traffic mark is reported to the SMF network element, and the SMF network element sends Non-GBR flow to the UPF network element, modifies the priority of the white list QoS flow and reduces the priority to Non-guaranteed flow.
Example III
Referring to fig. 2, a dynamic control terminal for QoS flows includes a memory, a processor, and a computer program stored in the memory and capable of running on the processor, where the processor implements the steps of the dynamic control method for QoS flows according to the first embodiment when executing the computer program.
In summary, the method and the terminal for dynamically controlling QoS flows set up a service blacklist and a service whitelist based on user information and names of application programs, and are stored in a unified data management module; acquiring a session establishment request of a user and a business black-and-white list of the user, and periodically caching the IP addresses of the application programs in the business black-list and the business white-list to a strategy control function network element, so as to dynamically update the IP addresses of the application programs; if the user is configured with a white list, configuring configuration information of the service white list to a strategy control function network element, binding the configuration information with the corresponding user one by one, facilitating subsequent processing of the white list service, improving the priority of the white list QoS flow when receiving the white list service data message, and reducing the priority of the white list QoS flow when stopping receiving the white list service data message; if the user is configured with the blacklist, discarding the blacklist service data message received by the QoS flow; therefore, based on the service black-and-white list of the user and the state of receiving the data message, the QoS flow can be dynamically adjusted according to the service type of the user, the QoS flow is adjusted according to the actual service use condition, and the bandwidth resources are configured as required, so that the full and effective utilization of the bandwidth resources is realized, and the utilization rate of the bandwidth resources is improved.
