[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The network fluctuation analysis method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the NWDAF network element 104 responds to the network fluctuation analysis request carrying the service analysis identifier sent by the first NF network element 102, determines the second NF network element 106 associated with the network to be analyzed according to the service analysis identifier; and determines the network fluctuation analysis report of the network to be analyzed according to the historical resource usage of the second NF network element 106. The NWDAF network element 104 sends the network fluctuation analysis report to the first NF network element.

[0055] Among them, NWDAF (Network Data Analytics Function) network element, as an important component of 5G network, is designed to simplify the generation and use of core network data, and generate insights and take actions to enhance the end-user experience.

[0056] NF (Network Function) is an entity that provides various services in the 5G core network system.

[0057] In one embodiment, Figure 2 is a flow chart of a network fluctuation analysis method provided in accordance with an embodiment of the present application, wherein the method is applied to Figure 1 Taking the NWDAF network element in FIG. 1 as an example, the method includes the following steps:

[0058] S201, in response to a network fluctuation analysis request carrying a service analysis identifier sent by a first NF network element, determine a second NF network element associated with the network to be analyzed according to the service analysis identifier.

[0059] Among them, the first NF network element refers to the consumer NF network element that requests network fluctuation analysis. The second NF network element refers to the NF network element associated with the network to be analyzed, for example, AMF network element, UDM network element, UPF network element, etc. The business analysis identifier indicates the identifier corresponding to the analyzed business. For example, it is an analysis ID for the entire network, an analysis ID for the regional network, or an exclusive ID for a drone cluster of a logistics company. The network to be analyzed refers to the communication network that needs to perform network fluctuation analysis.

[0060] As an optional implementation of the embodiment of the present application, in response to a network fluctuation analysis request carrying a business analysis identifier sent by a first NF network element, the network fluctuation analysis request is parsed to obtain a business analysis identifier. According to the analysis identifier list and the business analysis identifier, a second NF network element associated with the network to be analyzed is determined. Among them, the analysis identifier list records various business analysis identifiers, as well as the mapping relationship between each business analysis identifier and the NF network element.

[0061] As another optional implementation of the embodiment of the present application, in response to a network fluctuation analysis request carrying a service analysis identifier sent by a first NF network element, a network to be analyzed is determined according to the service analysis identifier, and a network element in the network to be analyzed is used as a second NF network element associated with the network to be analyzed.

[0062] S202: Determine a network fluctuation analysis report of the network to be analyzed based on the historical resource usage of the second NF network element.

[0063] The historical resource usage refers to the usage of network resources of the second NF network element within a preset historical period, and the network resources include but are not limited to CPU utilization and memory utilization, etc. The network fluctuation analysis report refers to an analysis report that records the relationship between network fluctuation and time.

[0064] Optionally, in this embodiment, a resource usage acquisition request is sent to the OAM network element, so that the OAM network element feeds back the historical resource usage of the second NF network element to the NWDAF network element based on the resource usage acquisition request. The resource usage acquisition request carries at least the network element identifier of the second NF network element.

[0065] As an optional implementation of the embodiment of the present application, the historical resource usage of the second NF network element is input into the network fluctuation analysis model, and the network fluctuation analysis model outputs the network fluctuation analysis situation. Based on the network fluctuation analysis situation, a network fluctuation analysis report is generated. Among them, the network fluctuation analysis model includes but is not limited to a neural network model.

[0066] As another optional implementation of the embodiment of the present application, the correlation between network resources and network fluctuations is determined based on the historical resource usage of the second NF network element and the historical network fluctuations of the network to be analyzed. Based on the historical resource usage, the resource usage of the network to be analyzed in the future time period is predicted. Based on the resource usage in the future time period and the correlation between network resources and network fluctuations, the network fluctuations in the future time period are predicted. Based on the network fluctuations in the future time period, a network fluctuation analysis report for the network to be analyzed is generated.

[0067] S203, sending a network fluctuation analysis report to the first NF network element.

[0068] As an optional implementation of the embodiment of the present application, the NWDAF network element directly sends a network fluctuation analysis report to the first NF network element.

[0069] As another optional implementation of the embodiment of the present application, the NWDAF network element indirectly sends the network fluctuation analysis report to the first NF network element through other network elements.

[0070] The above-mentioned network fluctuation analysis method responds to the network fluctuation analysis request sent by the first NF network element and carries a business analysis identifier, and determines the second NF network element associated with the network to be analyzed according to the business analysis identifier. According to the historical resource usage of the second NF network element, a network fluctuation analysis report of the network to be analyzed is determined. The network fluctuation analysis report is sent to the first NF. The present application can determine the second NF network element associated with the network to be analyzed according to the business analysis identifier through the NWDAF network element. According to the historical resource usage of the second NF network element, a network fluctuation analysis report of the network to be analyzed is determined to realize the network fluctuation of the network to be analyzed. The present application not only improves the efficiency of network fluctuation analysis, but also the relevant network elements can process network fluctuations in a targeted manner based on the network fluctuation analysis report, thereby improving the service quality of the network to be analyzed.

[0071] In one of the embodiments, in order to more accurately determine the second NF network element associated with the network to be analyzed, such as Figure 3 As shown, an optional implementation of S201 includes:

[0072] S301, determining the terminal participation status of this network analysis according to the business analysis identifier.

[0073] The terminal participation status refers to whether the current network analysis needs to include the user terminal for combined analysis.

[0074] As an optional implementation of the embodiment of the present application, the terminal parameter status of this network analysis is determined according to the business analysis identifier and the analysis identifier list. Among them, the analysis identifier list records various business analysis identifiers, and each business analysis identifier and the associated user terminal. If the business analysis identifier has an associated user terminal, it is characterized that the terminal participation status corresponding to the business analysis identifier requires user terminal participation.

[0075] As another optional implementation of the embodiment of the present application, the business analysis identifier is analyzed to determine the terminal participation in this network analysis. For example, if the business analysis identifier is an analysis ID for the core network as a whole, that is, a network fluctuation analysis of the core network as a whole, this may not require terminal participation. If the business analysis identifier is an exclusive ID for a certain logistics company's drone group, this requires terminal participation.

[0076] S302: Determine the second NF network element associated with the network to be analyzed according to the terminal participation status and the service analysis identifier.

[0077] Optionally, in this embodiment, when the terminal participation situation requires the user terminal to participate, a first information acquisition request is sent to the mobile management device. The current location information of the user terminal fed back by the mobile management device based on the first information acquisition request is received. According to the service analysis identifier and the current location information of the user terminal, the second NF network element associated with the network to be analyzed is determined. Among them, the mobile management device can be but is not limited to an AMF (Access and Mobility Management Function) network element.

[0078] In this embodiment, an optional implementation method for sending a first information acquisition request to a mobile management device is to determine the terminal identifier based on the business analysis identifier. Based on the terminal identifier, a first information acquisition request is generated so that the mobile management device obtains the current location information of the user terminal based on the terminal identifier. For example, the business analysis identifier is a specific ID for a certain logistics company's drone swarm, and the specific ID of the drone swarm can be used as the terminal identifier. Optionally, in this embodiment, the NWDAF network element can send a first information acquisition request to the mobile management device through a service-based interface.

[0079] In this embodiment, an optional implementation method for determining the second NF network element associated with the network to be analyzed based on the business analysis identifier and the current location information of the user terminal is to send a second information acquisition request to the application function device. Receive the terminal task plan of the user terminal fed back by the application function device based on the second information acquisition request. Determine the second NF network element associated with the network to be analyzed based on the terminal task plan, the business analysis identifier and the current location information of the user terminal. Among them, the application function device adopts but is not limited to the AF (Application Function) network element.

[0080] Optionally, the terminal task plan in this embodiment includes but is not limited to at least one of a planned start time, a planned end time, a planned duration, a planned start point and a planned end point.

[0081] In this embodiment, an optional implementation of sending the second information acquisition request to the application function device is that the NWDAF network element sends the second information acquisition request to the application function device through a service-based interface.

[0082] Another optional implementation of sending the second information acquisition request to the application function device in this embodiment is that the NWDAF network element forwards the second information acquisition request to the application function device through a NEF (Network Element Function) network element.

[0083] In this embodiment, an optional implementation method of determining the second NF network element associated with the network to be analyzed according to the terminal task plan, the service analysis identifier and the current location information of the user terminal is to create a target screening condition according to the terminal task plan, the service analysis identifier and the current location information of the user terminal. According to the target screening condition, the second NF network element associated with the network to be analyzed is queried. For example, it can be obtained through local query or by querying other external devices.

[0084] In this embodiment, an optional implementation method for determining the second NF network element associated with the network to be analyzed based on the terminal task plan, the service analysis identifier and the current location information of the user terminal is to determine the candidate second NF network element associated with the analysis service corresponding to the service analysis identifier in the network to be analyzed based on the service analysis identifier.

[0085] According to the terminal task plan and the current location information of the user terminal, the mobile area of ​​the user terminal is determined. According to the management area of ​​each candidate second NF network element, a candidate second NF network element whose management area and mobile area overlap is selected as the second NF network element associated with the network to be analyzed.

[0086] Optionally, in this embodiment, when the terminal participation situation does not require user terminal participation, the second NF network element associated with the network to be analyzed can be determined based on the service analysis identifier.

[0087] In this embodiment, the terminal participation in this network analysis is determined according to the business analysis identifier. According to the terminal participation and the business analysis identifier, the second NF network element associated with the network to be analyzed is determined. In this embodiment, the terminal participation is also considered when determining the business analysis identifier. And when the terminal participation requires the user terminal to participate, based on the terminal task plan and the current location information of the user terminal, the second NF network element associated with the network to be analyzed is further screened to obtain the second NF network element, so that the obtained second NF network element is more accurate, which not only effectively improves the efficiency of network fluctuation analysis, but also greatly improves the accuracy of network fluctuation analysis.

[0088] In one embodiment, in order to improve the accuracy of network fluctuation analysis, Figure 4 As shown, an optional implementation of S202 includes:

[0089] S401, obtaining historical network fluctuation information of the network to be analyzed.

[0090] The historical network fluctuation information refers to the network fluctuation situation and network alarm situation of the network to be analyzed in a preset historical period.

[0091] Optionally, in this embodiment, the network fluctuation analysis request is divided into a network fluctuation analysis subscription request and a network fluctuation analysis direct request. In the case where the network fluctuation analysis request is a network fluctuation analysis subscription request, the network fluctuation analysis request at least carries a service analysis identifier. In the case where the network fluctuation analysis request is a network fluctuation analysis direct request, the network fluctuation analysis request at least carries a service analysis identifier and historical network fluctuation information.

[0092] As an optional implementation of the embodiment of the present application, when the network fluctuation analysis request is a network fluctuation analysis subscription request, the NWDAF network element sends a fluctuation information acquisition request to the OAM network element, so that the OAM network element feeds back historical network fluctuation information to the NWDAF network element based on the fluctuation information acquisition request.

[0093] As another optional implementation of the embodiment of the present application, when the network fluctuation analysis request is a direct request for network fluctuation analysis, the NWDAF network element can parse the network fluctuation analysis request to obtain historical network fluctuation information. It should be noted that in this embodiment, when the NWDAF network element determines that the historical network fluctuation information does not meet the requirements (for example, the information is incomplete), the NWDAF network element can also send a fluctuation information acquisition request to the OAM network element, so that the OAM network element feeds back the historical network fluctuation information to the NWDAF network element based on the fluctuation information acquisition request.

[0094] S402: Determine a network fluctuation analysis report for the network to be analyzed based on historical network fluctuation information and historical resource usage of the second NF network element.

[0095] As an optional implementation of the embodiment of the present application, historical network fluctuation information and historical resource usage of the second NF network element are input into a network fluctuation analysis model, and the network fluctuation analysis model performs network fluctuation analysis on the network to be analyzed and outputs a network fluctuation analysis report. The network fluctuation analysis model may be a neural network model.

[0096] Optionally, the network fluctuation analysis report in this embodiment includes at least one of time information, network fluctuation events, fluctuation-associated NF network elements, and network fluctuation levels. Wherein, a network fluctuation event refers to a specific event of network fluctuation (for example, traffic exceeds load). The network fluctuation level refers to the severity level of network fluctuation, which can be divided into high risk, medium risk, and low risk.

[0097] The network fluctuation events in this embodiment may not only include historical network fluctuation events, but also predict network fluctuation events in future periods.

[0098] The network fluctuation analysis report in this embodiment can be associated with the terminal task plan in the above embodiment; the network fluctuation analysis report includes the predicted network fluctuation events between the planned start time and the planned end time in the terminal task plan, as well as the fluctuation-associated NF network elements and network fluctuation levels.

[0099] In this embodiment, based on the analysis or prediction of network fluctuation events, a basis is provided for the execution or generation of corresponding measures (for example, network elements or network management do not handle certain low-risk network fluctuations, etc.), thereby suppressing / avoiding the network's overreaction to low-risk network fluctuations (i.e., low-level network fluctuations) (for example, frequent expansion and contraction of network elements due to short-term medium to high loads on network elements), wasting resources required for risk processing, and even causing abnormal fluctuations in the virtual resource layer.

[0100] In one embodiment, if Figure 5 As shown, an optional implementation of a network fluctuation analysis method includes:

[0101] S501, the NWDAF network element receives a network fluctuation analysis request carrying a service analysis identifier sent by the first NF network element.

[0102] S502: The NWDAF network element determines the terminal participation status of this network analysis according to the service analysis identifier.

The obtaining method includes parsing the network fluctuation analysis request to obtain the historical network fluctuation information of the network to be analyzed; and / or obtaining the historical network fluctuation information of the network to be analyzed through an OAM network element.

[0111] S511, the NWDAF network element sends a network fluctuation analysis report to the first NF network element.

[0112] In this embodiment, in response to a network fluctuation analysis request carrying a business analysis identifier sent by the first NF network element, a second NF network element associated with the network to be analyzed is determined according to the business analysis identifier. Based on the historical resource usage of the second NF network element, a network fluctuation analysis report of the network to be analyzed is determined. The network fluctuation analysis report is sent to the first NF. This application can determine the second NF network element associated with the network to be analyzed according to the business analysis identifier through the NWDAF network element. Based on the historical resource usage of the second NF network element, a network fluctuation analysis report of the network to be analyzed is determined to achieve the network fluctuation of the network to be analyzed. This application not only improves the efficiency of network fluctuation analysis, but also the relevant network elements can process network fluctuations in a targeted manner based on the network fluctuation analysis report, thereby improving the service quality of the network to be analyzed.
