Step S100: when receiving a session creation request sent by the SMF, determining target service information according to the session creation request;
in some embodiments, the UE initiates a PDU (Protocol Data Unit ) session creation request that the SMF sends to the second network node carrying the target traffic information to let the second network node determine the target traffic information.
It should be noted that, the session creation request includes, but is not limited to, parameters including a user number, a data network name, a slice, a PDU session identifier, a request type, a user identifier, location area information, and the like, and the embodiment is not limited in particular.
Step S200: determining a monitoring rule corresponding to the target service information according to the target service information;
it should be noted that, the monitoring rule is used for detecting the service usage situation of the terminal.
In some embodiments, the service type, the service range, and the like of the target service information are determined according to a plurality of parameter information in the target service information, and a corresponding monitoring rule is determined according to the service type of the target service information so as to detect the service use condition of the terminal.
It is understood that the monitoring rule may be a predefined monitoring rule or a monitoring rule with traffic flow, which in this embodiment is an ADC rule (Application Detection and Control, apply detection control).
Step S300: sending the monitoring rule to the SMF to receive service occurrence event information returned by the SMF, and generating a protection strategy of the target service according to the service occurrence event information;
it should be noted that, the service occurrence event information is used to characterize that the monitoring rule detects that the terminal is using the target service.
In some embodiments, the second network node sends the monitoring rule to the SMF, so that the SMF stores the monitoring rule, records the target service that the monitoring rule detects that the terminal is using, thereby obtaining service occurrence event information, and generates a protection policy corresponding to the target service according to the service occurrence event information, thereby implementing specific protection on the target service.
It should be noted that, the protection policy includes rules such as QoS guarantee and charging policy issued for the target service.
Step S400: and sending the protection strategy to the SMF to realize the protection of the target service.
In some embodiments, the second network node sends the protection policy to the SMF, so that the SMF guarantees the target service according to the protection policy, thereby meeting the application requirement of the target service, and being capable of providing differentiated services for users of different levels.
In some embodiments, the target traffic information includes at least one of: cell congestion information of the user, the cell congestion information is used for representing the network performance of a cell in which the user is located; the subscription package of the user can screen out users with different grades and accurately judge the service types of the users, so that differentiated services can be conveniently provided for the users with different grades, and the instruction pressure of reporting service information is avoided.
In some embodiments, the subscriber's subscription package is configured by the PCF or is signed up through the UDR.
It should be noted that, the subscription package of the user is a user-specific package, for example, a voice call package, a video traffic package, a voice call package, a broadband service, and the like.
Referring to fig. 3, fig. 3 is a flowchart of acquiring cell congestion information according to another embodiment of the present invention, including but not limited to steps S500 to S600.
The session creation request includes location area information.
Step S500: when NWDAF information corresponding to the location area information is locally absent, the location area information is sent to the NRF to enable the NRF to return to NWDAF information of the cell, and NWDAF information is sent to the NWDAF to acquire cell congestion information corresponding to the location area information;
it should be noted that NWDAF information is used to characterize the ability of the network to analyze data.
Step S600: when NWDAF information corresponding to the location area information is locally present, NWDAF information is transmitted to NWDAF to acquire cell congestion information corresponding to the location area information.
In some embodiments, after receiving a session creation request sent by an SMF, a second network node stores location area information in the session creation request, and when it is found that NWDAF information corresponding to the location area information is absent locally, it is required to obtain cell congestion information of the cell according to the location area information, at this time, it is required to send the location area information to an NRF, so that the NRF finds NWDAF information corresponding to the location area and returns the NWDAF information to the second network node, and then the second network node sends the NWDAF information to the NWDAF, so that congestion conditions of the location area corresponding to the location area information can be obtained according to the NWDAF information, and cell congestion information can be obtained according to the congestion conditions, so that service decision can be conveniently performed according to the cell congestion information subsequently, and different protection policies can be issued; when it is determined that NWDAF information corresponding to the location area information exists locally, the NWDAF information may be directly transmitted to the NWDAF to acquire cell congestion information corresponding to the location area information.
In the process of transmitting the location area information to the NRF to return the NRF to the NWDAF information of the cell, the NWDAF information is found to the NRF, along with parameter information such as a slice, an analysis type, and a location area.
It is to be understood that the cell congestion information includes, but is not limited to, information including cell information, cell congestion type, cell congestion level, etc., and the present embodiment is not particularly limited.
Referring to fig. 4, fig. 4 is a further illustration of step S600 in fig. 3, step S600 including, but not limited to, steps S610 through S620.
Step S610: generating a congestion control request according to the NWDAF information and the location area information;
step S620: a congestion control request is sent to the NWDAF such that the NWDAF returns cell congestion information according to the congestion control request.
In some embodiments, after NWDAF information corresponding to the location area information is locally present, the second network node generates a congestion control request according to the NWDAF information and the location area information, and sends the congestion control request to the NWDAF to obtain cell congestion information, so as to facilitate determination of a subsequent monitoring rule.
It should be noted that, the congestion control request carries parameter information such as an analysis type, location area information, and the like, where the location area information may be a user level, a TAI level (Tracking Area Identity, tracking area identifier), a cell level, or the like, and the embodiment is not limited specifically.
It can be understood that the cell congestion information can be preset and acquired in real time, and when the cell congestion information is acquired in advance, the second network node immediately acquires the cell congestion condition from the NWDAF when receiving the location area information; when the cell congestion information is obtained in real time, the second network node needs to detect whether the target service needs to obtain the cell congestion condition from the NWDAF when receiving the service occurrence event.
Referring to fig. 5, fig. 5 is a further illustration of step S300 in fig. 2, step S300 including, but not limited to, steps S310 to S330.
Step S310: establishing a session creation response corresponding to the session creation request;
step S320: sending monitoring rules to the SMF through session creation response;
step S330: and receiving a session update request sent by the SMF and service occurrence event information sent by the session update request.
In some embodiments, after receiving a session creation request sent by the SMF and determining target service information, a session creation response corresponding to the session creation request is established, so that a monitoring rule is sent to the SMF through the session creation response, and a session update request sent by the SMF and service occurrence event information sent by the session update request are received, where the session update request carries parameters such as service occurrence event information and service flow, so as to monitor and update the target service.
It should be noted that, after the second network node sends the monitoring rule to the SMF through the session update request, the SMF stores the monitoring rule, and forwards the monitoring rule to a UPF (User Plane Function ) to detect whether the terminal is using the target service, if the result of the UPF detection is that the terminal is using the target service, reporting the service occurrence event information to the second network node through the SMF, thereby completing detection of the target service through the monitoring rule.
Referring to fig. 6, fig. 6 is a further illustration of step S400 in fig. 2, step S400 including, but not limited to, steps S410 through S420.
Step S410: establishing a session update response corresponding to the session update request;
step S420: and sending a protection policy to the SMF based on the session update response to realize the protection of the target service.
In some embodiments, after receiving the session update request sent by the SMF, the second network node establishes a session update response corresponding to the session update request, and sends the protection policy to the SMF through the session update response, so as to provide a service-level QoS guarantee, a charging manner, and other protection policies for the target service.
It should be noted that, the protection policy may be obtained by making a decision for the second network node according to the congestion information of the cell, for example, the congestion level, the congestion class, and so on.
Referring to fig. 7, fig. 7 is a flowchart of a network data processing method according to another embodiment of the present invention, including but not limited to steps S430 to S450.
Step S430: receiving service end event information sent by SMF through session update request;
it should be noted that, the service end event information is obtained by detecting the target service by the UPF, where the service end event information is used to characterize that the monitoring rule detects that the terminal stops using the target service;
step S440: generating a deleting instruction according to the service ending event information;
it should be noted that, the deletion instruction is used for deleting the protection policy of the target service;
step S450: and sending a deletion instruction to the SMF through the session update response.
In some embodiments, after the protection policy is sent to the SMF, the second network node receives service end event information sent by the SMF through the session update request, generates a deletion instruction for deleting the protection policy of the target service according to the service end event information, and sends the deletion instruction to the SMF through the session update response, thereby deleting the protection policy such as QoS guarantee, charging mode, and the like.
After the UPF detects that the terminal in the monitoring rule stops using the target service, the SMF reports the service end event information to the second network node, and the SMF sends parameters such as the service end event information to the PCF through the session update request, thereby implementing location tracking of the target service and deletion of the protection policy.
Referring to fig. 8, fig. 8 is a flowchart of a network data processing method according to another embodiment of the present invention, including, but not limited to, steps S700-S1000.
Step S700: receiving an area switching request sent by an SMF;
step S800: sending an area switching request to the NWDAF so that the NWDAF returns switching congestion information of a switching cell according to the area switching request;
step S900: generating a switching protection strategy according to the switching congestion information and the regional switching request;
step S1000: and sending the switching protection strategy to the SMF through a session update response.
In some embodiments, when the location of the UE is switched or changed, the SMF carries parameters such as new location area information, and sends an area switching request to the second network node through a session update request, and when the second network node finds that there is no local switching congestion information of a switching cell where the new location area information is located, the second network node sends the area switching request to the NWDAF, so that the NWDAF returns the switching congestion information of the switching cell according to the area switching request, and the second network node generates a switching protection policy of the switching service according to the switching congestion information and the area switching request, and sends the switching protection policy to the SMF through a session update response, so as to implement protection of the switching service, thereby accurately obtaining the switching congestion information and performing specific protection on the switching service.
Note that, the handover congestion information includes information such as handover cell information, handover cell congestion type, and handover cell congestion level, which is not particularly limited in this embodiment.
In some embodiments, after receiving the area handover request sent by the SMF, if the second network node finds that there is handover congestion information of the handover cell where the new location area information is located locally, the second network node may directly generate a handover protection policy according to the handover congestion information and the area handover request, and send the handover protection policy to the SMF to perform protection of the handover service.
In some embodiments, the network data processing method further includes updating cell congestion information of the cell at intervals of a preset time interval, so as to avoid the situation that the cell congestion information is out of date, and update the cell congestion information in time, so as to avoid the situation that information leakage occurs.
It should be noted that, the second network node updates the cell congestion information of the cell at preset time intervals, and after the second network node senses that the cell congestion information corresponding to the locally cached location area information is out of date, the second network node re-acquires the cell congestion information of the cell, and sends a new round of congestion control request to the NWDAF according to the updated location area information, so as to acquire the cell congestion information of the updated cell, and the like, and re-decides the protection policy of the updated service according to the latest cell congestion information, thereby realizing real-time tracking of the cell where the user using the service is located, improving service usage experience of the user, protecting specific service, and improving resource utilization rate.

step 2: the PCF obtains the subscription package of the user, issues a monitoring rule (a predefined monitoring rule or a monitoring rule with service flow), and the exclusive package of the user can be configured locally by the PCF or can be realized by UDR subscription;
step 3: the PCF replies session creation response to the SMF, carrying application monitoring rules;
step 4: the SMF stores the monitoring rules and forwards the monitoring rules to the UPF to detect whether the service is used or not;
step 5: the UPF detects the service use of the monitoring rule, and reports the service occurrence event information to the PCF through the SMF;
step 6: the SMF sends parameters such as event information, service flow and the like of the monitoring service to the PCF through a session updating request;
step 7: the PCF stores the position area information of the cell, and if the cell congestion information of the cell is not locally available and the detection application needs the cell congestion information, the cell congestion information of the cell is obtained according to the position area information;
step 8: if the PCF does not find out the NWDAF information of the cell congestion from the NRF, the PCF sends parameters such as a carrying slice, an analysis type, position area information and the like to the NRF;
step 9: NRF returns NWDAF information providing congestion information of the cell to PCF;
step 10: the PCF acquires the congestion condition of the position area information from the NWDAF according to the returned NWDAF information;
step 11: the PCF sends a congestion control request to the NWDAF according to the position area information to acquire the cell congestion information of the cell, wherein the congestion control request carries parameters such as analysis type, position area (possibly user level, TAI level or cell level) and the like;
step 12: the NWDAF returns the cell congestion information, including the information of cell information, cell congestion type, cell congestion level and the like;
step 13: the PCF decides the QoS guarantee, charging policy and other protection policies of the target service according to the cell congestion information such as congestion level, congestion type and the like;
step 14: the PCF replies session update response to the SMF and provides QoS guarantee, charging policy and other protection policies of the target service of the service level;
step 15: the UPF detects the service end of the monitoring rule, and reports the service end event information to the PCF through the SMF;
step 16: the SMF sends the information carrying the service ending event to the PCF through the session updating request;
step 17: the PCF deletes the QoS guarantee, charging policy and other protection policies of the target service, and no dedicated guarantee is provided;
step 18: the PCF replies a session update request response to the SMF, and deletes the QoS guarantee, charging policy and other protection policies of the service level.
Example three:
referring to fig. 11, fig. 11 is an exemplary diagram of a network data processing method provided by a specific example of the present invention;
an example three is a step flow of updating location area information of a cell to reacquire cell congestion information:
step 1: the position area information of the UE is switched, the SMF carries new position area information and other parameters, and the new position area information is sent to the PCF through a session update request;
step 2: the PCF finds that the congestion information of the new position area information does not exist locally, and then the cell congestion information of the cell is obtained according to the new position area information;
step 3: the PCF sends a congestion control request to the NWDAF according to the location area information to acquire the cell congestion information of the cell, wherein the congestion control request carries parameters such as analysis type, location area (possibly user level, TAI level or cell level) and the like;
step 4: the NWDAF returns the cell congestion information, including the information of cell information, cell congestion type, cell congestion level and the like;
step 5: the PCF decides the QoS guarantee, charging policy and other protection policies of the service according to the cell congestion information such as congestion level, congestion type and the like;

Example four:
referring to fig. 12, fig. 12 is an exemplary diagram of a network data processing method provided by a specific example of the present invention;
the fourth example is a step flow of acquiring cell congestion information again due to expiration of cell congestion information of a cell:
step 1: the PCF senses that the cell congestion information of the locally cached location area information is out of date, and re-acquires the cell congestion information of the cell;
step 2: the PCF acquires the cell congestion control information of the cell from the NWDAF according to the position area information, and carries parameters such as analysis type, position area information (possibly user level, TAI level or cell level) and the like;
step 3: the NWDAF returns the cell congestion information, including the information of cell information, cell congestion type, cell congestion level and the like;
step 4: the PCF re-decides the QoS guarantee, charging policy and other protection policies of the detection service according to the latest cell congestion information such as congestion level, congestion type and the like;
step 5: PCF sends session association notification request to SMF, and provides QoS guarantee of service level, charging policy and other protection policies;
step 6: the SMF replies to the PCF with a session association notification reply.
In some embodiments, the PCF senses that the cell congestion information of the locally cached location area information is out of date, and re-acquires the cell congestion information of the cell, so as to monitor the cell congestion information in real time, and avoid information leakage and other situations.
