Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a method, system, device, medium, and program product for updating network slice configuration. Background Technology

[0002] 5G introduces network slicing technology and NFV (Network Functions Virtualization) capabilities, enabling operators to build multiple dedicated, virtualized, and logically isolated network slices on top of a common physical network to meet the diverse quality of service requirements of the 5G industry. A network slice typically consists of three parts: a radio network sub-slice, a bearer network sub-slice, and a core network sub-slice.

[0003] The 5G core network introduces Network Data Analytics Function (NWDAF) network elements. These elements collect data from the 5G network and use advanced technologies such as artificial intelligence, machine learning, and inference to analyze and predict the raw data intelligently. The analysis results are then output to consumers, such as 5GC Network Function (NF) network elements, Application Function (AF) network elements, and Operation Administration and Maintenance (OAM) network elements. These elements are used to optimize network resource utilization and improve the user terminal service experience.

[0004] However, the slice management solutions provided in related technologies mainly adopt manual static configuration for deployment and do not currently support the ability to dynamically adjust slice configurations based on slice load conditions, etc. They lack a solution for dynamically optimizing and adjusting end-to-end slice configurations based on network slice load statistics. Summary of the Invention

[0005] This disclosure provides a method, system, device, media, and program product for updating network slice configurations, improving the efficiency of updating and optimizing network slice configurations. The technical solution of this disclosure is as follows:

[0006] According to a first aspect of this disclosure, a method for updating network slice configuration is provided, comprising:

[0007] In response to receiving a slice analysis request sent by a first network element, the Network Data Analysis Function (NWDAF) network element determines a second network element corresponding to the first network element and the target analysis identifier. The first network element is a Network Slice Management Function (NSMF) network element, a Slice Subnet Management Function (NSSMF) network element, or a Network Function (NF) network element. The slice analysis request includes the target analysis identifier and the identifier of the target network slice to be analyzed.

[0008] In the second network element, the NWDAF network element obtains the slice parameter configuration value, slice parameter usage value, and slice status information associated with the target network slice identifier, and determines the slice indicator analysis and prediction result of the target network slice based on the slice parameter configuration value, slice parameter usage value, and slice status information, and sends the slice indicator analysis and prediction result to the first network element. The slice indicator analysis and prediction result includes the analysis and prediction result parameter value of the indicator associated with the target analysis identifier, or the slice suggestion adjustment value corresponding to the analysis and prediction result parameter value.

[0009] The first network element determines the update result of the target network slice based on the slice indicator analysis and prediction results, and updates the target network slice based on the update result, wherein the update result is the updated slice configuration information or the updated service quality assurance strategy information.

[0010] According to a second aspect of this disclosure, a network slice configuration update system is provided, comprising:

[0011] The Network Data Analysis Function (NWDAF) network element is configured to, in response to receiving a slice analysis request sent by a first network element, determine a second network element corresponding to the first network element and the target analysis identifier. The first network element is a Network Slice Management Function (NSMF) network element, a Slice Subnet Management Function (NSSMF) network element, or a Network Function (NF) network element. The slice analysis request includes the target analysis identifier and the identifier of the target network slice to be analyzed.

[0012] The NWDAF network element is further configured to, in the second network element, obtain the slice parameter configuration value, slice parameter usage value, and slice status information associated with the target network slice identifier, and determine the slice indicator analysis and prediction result of the target network slice based on the slice parameter configuration value, slice parameter usage value, and slice status information, and send the slice indicator analysis and prediction result to the first network element, wherein the slice indicator analysis and prediction result includes the analysis and prediction result parameter value of the indicator associated with the target analysis identifier, or the slice suggestion adjustment value corresponding to the analysis and prediction result parameter value;

[0013] The first network element is configured to determine the update result of the target network slice based on the slice indicator analysis and prediction results, and update the target network slice based on the update result, wherein the update result is updated slice configuration information or updated service quality assurance strategy information.

[0014] According to a third aspect of this disclosure, an electronic device is provided, comprising:

[0015] Processor; and

[0016] Stored program memory,

[0017] The program includes instructions that, when executed by the processor, cause the processor to perform the method as described in the first aspect.

[0018] According to a fourth aspect of this disclosure, a non-transitory computer-readable storage medium is provided storing computer instructions, wherein the computer instructions are configured to cause the computer to perform the method as described in the first aspect.

[0019] According to a fifth aspect of this disclosure, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the method as described in the first aspect.

[0020] The network slice configuration update method, system, device, medium, and program products disclosed herein, on the one hand, enable the determination of the second network element that needs to collect data when the first network element requests slice analysis in the target analysis scenario through NWDAF network elements. Based on the slice parameter configuration values, slice parameter usage values, and slice status information associated with the target network slice identifier obtained from the second network element, the slice indicator analysis and prediction results of the target network slice are determined, enriching the types of information obtained during network slice management and control. On the other hand, the slice indicator analysis and prediction results can be returned to the first network element that sent the slice analysis request, so that the first network element can update the target network slice based on the slice indicator analysis and prediction results. This achieves automatic updating and optimization of network slice configuration in a network architecture containing NWDAF network elements, improving the efficiency of network slice configuration updating and optimization.

[0032] To address the aforementioned problems, this disclosure provides a network slice configuration update scheme that can be applied to network elements on the core network side, such as... Figure 1 As shown, Figure 1 This illustration shows a schematic diagram of an implementation scenario for a network slice configuration update scheme provided by an exemplary embodiment of this disclosure. For example... Figure 1 As shown, the implementation scenario 100 includes a Network Data Analytics Function (NWDAF) network element 101 and a first network element. The first network element can be a Network Slice Management Function (NSMF) network element 102, a Network Slice Subnet Management Function (NSSMF) network element, or an NF network element 102. The NSMF network element can include an Access and Mobility Management Function (AN-NSSMF) network element 1031, a Transport Network-NetworkSlice Subnet Management Function (TN-NSSMF) network element 1032, and a Core Network-Network Slice Subnet Management Function (CN-NSSMF) network element 1033.

[0034] Figure 2A flowchart illustrating an exemplary embodiment of the present disclosure of a network slice configuration update method is shown. This method can be applied to network elements on the core network side, such as... Figure 2 As shown, the method in this embodiment of the disclosure may include:

[0035] Step S201: The Network Data Analysis Function (NWDAF) network element responds to the slice analysis request sent by the first network element and determines the second network element corresponding to the first network element and the target analysis identifier;

[0036] The first network element is either a Network Slice Management Function (NSMF) network element, a Slice Subnet Management Function (NSSMF) network element, or a Network Function (NF) network element. The slice analysis request includes the target analysis identifier and the identifier of the target network slice to be analyzed.

[0037] In step S202, the NWDAF network element in the second network element obtains the slice parameter configuration value, slice parameter usage value and slice status information associated with the target network slice identifier, and determines the slice index analysis and prediction result of the target network slice based on the slice parameter configuration value, slice parameter usage value and slice status information, and sends the slice index analysis and prediction result to the first network element.

[0038] The slice indicator analysis and prediction results include the analysis and prediction result parameter values ​​of the indicators associated with the target analysis identifier, or the slice suggested adjustment values ​​corresponding to the analysis and prediction result parameter values.

[0039] In step S203, the first network element determines the update result of the target network slice based on the slice index analysis and prediction results, and updates the target network slice based on the update result.

[0040] The update result is either the updated slice configuration information or the updated service quality assurance strategy information.

[0041] In summary, the network slice configuration update method provided in this disclosure, on the one hand, enables the determination of the second network element that needs to collect data when the first network element requests slice analysis in the target analysis scenario through the NWDAF network element, and determines the slice indicator analysis prediction result of the target network slice based on the slice parameter configuration value, slice parameter usage value, and slice status information associated with the target network slice identifier obtained in the second network element, thus enriching the types of information obtained when managing network slices; on the other hand, it can return the slice indicator analysis prediction result to the first network element that sent the slice analysis request, so that the first network element can update the target network slice according to the slice indicator analysis prediction result, realizing the automatic update and optimization of network slice configuration under the network architecture containing NWDAF network elements, and improving the efficiency of network slice configuration update and optimization.

[0042] The following are Figure 2 The specific implementation methods of each step in the illustrated embodiment are described in detail below:

[0043] In step S201, the Network Data Analysis Function (NWDAF) network element responds to receiving the slice analysis request sent by the first network element and determines the second network element corresponding to the first network element and the target analysis identifier;

[0044] In this embodiment of the disclosure, the first network element is a Network Slice Management Function (NSMF) network element, a Slice Subnet Management Function (NSSMF) network element, or a Network Function (NF) network element. The target analysis identifier can be determined based on actual needs, and this embodiment of the disclosure does not limit this. For example, the target analysis identifier can be slice load level information or service experience, etc., and the target network slice can be any one of multiple network slices after the communication network is deployed in a sliced ​​manner. It is understood that when the first network element is an NSMF network element, the NSMF network element can include an AN-NSSMF network element, a TN-NSSMF network element, and a CN-NSSMF network element.

[0045] It should be noted that, in this embodiment of the disclosure, the slice analysis request includes the target analysis identifier and the target network slice identifier to be analyzed. In the case that the first network element is an NSMF network element, the request sent by the NSMF network element may also include the target NSMF network element identifier. The target NSMF network element identifier may be any one or more of the AN-NSSMF network element identifier, TN-NSSMF network element identifier, and CN-NSSMF network element identifier, so as to realize the updating of configuration parameters related to the target network slice in the AN-NSSMF network element, TN-NSSMF network element, and / or CN-NSSMF network element based on the NSMF network element.

[0046] In one optional implementation, the first network element can send a slice analysis request to the NWDAF network element on demand, carrying analysis subscription period parameters. In response to receiving the slice analysis request sent by the first network element, the NWDAF network element can determine the second network element corresponding to the first network element and the target analysis identifier.

[0047] It should be noted that, in this embodiment of the disclosure, the first network element may also periodically request the NWDAF network element to analyze the slice status of the target network slice. The slice analysis subscription period of the target network slice can be determined based on actual needs, and this embodiment of the disclosure does not limit it. For example, the first network element may update the slice analysis subscription period of the target network slice once every 15 minutes or once every 30 minutes.

[0048] It should also be noted that in this embodiment of the disclosure, different first network elements require different data sources when requesting slice analysis of target network slices from different target analysis identifiers. Therefore, second network elements corresponding to different first network elements in different analysis dimensions can be pre-configured to obtain data source configuration information.

[0049] For example, when the first network element is an AN-NSSMF network element and the target analysis identifier is a slice load, the second network element corresponding to the AN-NSSMF network element and the slice load may include an AN-NSSMF network element and an OAM network element, etc. And when the first network element is a CN-NSSMF network element and the target analysis identifier is a slice load, the second network element corresponding to any one of the CN-NSSMF network elements and the slice load may include a CN-NSSMF network element, a core network management network element, a MANO network element, and a 5G NF network element, etc., wherein the NF network element may include a Policy Control Function (PCF) network element, an Access and Mobility Management Function (AMF) network element, and / or a Network Exposure Function (NEF), etc.

[0050] In one optional implementation, the process by which the NWDAF network element determines the second network element corresponding to the first network element and the target analysis identifier may include: the NWDAF network element may search for data source matching rule information to determine the second network element corresponding to the first network element and the target analysis identifier.

[0051] It should be noted that, in this embodiment of the disclosure, when the first network element is an NSMF network element, the NWDAF network element can refer to the NSMF network element identifier included in the slice analysis request during the process of determining the second network element corresponding to the first network element and the target analysis identifier. Specifically, when the slice analysis request includes an AN-NSSMF network element identifier, a TN-NSSMF network element identifier, and / or a CN-NSSMF network element identifier, the process of the NWDAF network element determining the second network element corresponding to the first network element and the target analysis identifier may include: determining the second network element corresponding to the AN-NSSMF network element and the target analysis identifier, or determining the second network element corresponding to the CN-NSSMF network element and the target analysis identifier, or determining the second network element corresponding to the TN-NSSMF network element and the target analysis identifier.

[0052] For example, if the target NSMF network element identifier in the slice analysis request is an AN-NSSMF network element identifier, then when the target analysis identifier is a slice load, the second network element corresponding to the NSMF network element and the slice load may include AN-NSSMF network elements and OAM network elements, etc.

[0053] Optionally, if the first network element is an NSMF network element, and the slice analysis request does not contain the target NSMF network element identifier, the configuration parameters related to the target network slice in the three types of NSMF network elements can be updated synchronously to improve the accuracy and reliability of the target network slice update.

[0054] In an optional implementation, when the first network element is an NSMF network element, the process by which the NWDAF network element determines the second network element corresponding to the first network element and the target analysis identifier may include: determining the second network element corresponding to the AN-NSSMF network element and the target analysis identifier, determining the second network element corresponding to the CN-NSSMF network element and the target analysis identifier, and determining the second network element corresponding to the TN-NSSMF network element and the target analysis identifier. During the configuration update process of the NSMF network element for the target network slice, the three types of NSWMF network elements can be coordinated to determine the data source and update the configuration parameters related to the target network slice in each NSWMF network element, thereby improving the accuracy of the target network slice configuration update.

[0055] It is understood that the process by which the NWDAF network element determines the second network element corresponding to the AN-NSSMF network element and the target analysis identifier, and determines the second network element corresponding to the CN-NSSMF network element and the target analysis identifier, or determines the second network element corresponding to the TN-NSSMF network element and the target analysis identifier, can refer to the process in the above embodiments by which the NWDAF network element determines the second network element corresponding to the first network element and the target analysis identifier. This disclosure will not elaborate on this process.

[0056] In step S202, the NWDAF network element in the second network element obtains the slice parameter configuration value, slice parameter usage value and slice status information associated with the target network slice identifier, and determines the slice index analysis and prediction result of the target network slice based on the slice parameter configuration value, slice parameter usage value and slice status information, and sends the slice index analysis and prediction result to the first network element.

[0057] In this embodiment of the disclosure, the slice indicator analysis and prediction results may include, or, the analysis and prediction result parameter values ​​of the indicators associated with the target analysis identifier, or the slice suggested adjustment values ​​corresponding to the analysis and prediction result parameter values. Specifically, when the target analysis identifier is slice load, the analysis and prediction result parameter value of the indicator associated with the target analysis identifier is the slice load rate; when the target analysis identifier is quality of service, the analysis and prediction result parameter value of the indicator associated with the target analysis identifier is the quality of service parameter value. The slice suggested adjustment values ​​include suggested adjustment values ​​for slice parameters of the target network slice or suggested adjustment values ​​for service quality assurance policy parameters. Slice parameters are relevant parameters that need to be configured during the deployment of the target network slice, such as computing resources, storage resources, slice bandwidth, and / or service processing capacity per unit time. Quality assurance parameters can be Quality of Service (QoS) related parameters, such as the QoS level identifier (5G QoS Identifier, 5QI) and rate in 5G.

[0058] It should be noted that, in this embodiment, the slice status information is used to characterize the slice's own operational status. The slice status information may include: slice load, slice computation usage information, slice storage resource usage information, and slice network resource usage information, etc. When different first network elements request slice analysis of a target network slice from different target analysis identifiers, they need to obtain different slice parameter configuration values, slice parameter usage values, and slice status parameters from different second network elements. Therefore, the slice parameter types associated with the second network elements corresponding to different first network elements in different analysis dimensions can be pre-configured in the data source configuration information. Specifically, this can be determined based on actual needs, and this embodiment does not limit this.

[0059] For example, when the first network element is an AN-NSSMF network element or an NSSMF network element, and the target analysis identifier is a slice load, the slice parameter types associated with either the AN-NSSMF network element or the NSSMF network element, as well as the second network element such as the AN-NSSMF network element and the OAM network element corresponding to the slice load, may include: the number of available physical resource blocks (PRBs) for uplink and downlink, the number of registered users in the target network slice, the number of sessions established in the target network slice, uplink and downlink bandwidth, packet loss rate, and latency, etc.

[0060] When the first network element is an NSMF network element or a CN-NSSMF network element, and the target analysis identifier is a slice load, the slice parameter types associated with any of the NSMF network elements or CN-NSSMF network elements, as well as the CN-NSSMF network elements, core network management network elements, MANO network elements, and NF network elements of the 5G core network corresponding to the slice load, may include: the number of registered users of the target network slice, uplink and downlink bandwidth, and the resource quantity of the relevant nodes of the target network slice, etc.

[0061] When the first network element is an NSMF network element or a TN-NSSMF network element, and the target analysis identifier is a slice load, the slice parameter type associated with any of the NSMF network elements or TN-NSSMF network elements, as well as the second network element such as the TN-NSSMF network element and the transmission / bearer network management network element corresponding to the slice load, can include: the bandwidth of the transmission subnet slice, etc.

[0062] When the first network element is an NF network element and the target analysis identifier is slice load, the slice parameter types associated with the second network element, such as the NSSMF network element (AN-NSSMF network element, TN-NSSMF network element, and / or CN-NSSMF network element), OAM network element, MANO network element, and / or NF network element, can include: the number of registered users of the target network slice, the resource quantity of the relevant nodes of the target network slice, the number of uplink and downlink PRBs, the bandwidth of the target network slice, the number of sessions established in the target network slice, the uplink and downlink bandwidth, packet loss rate, and latency, etc.

[0063] In one optional implementation, the process by which the NWDAF network element obtains the slice parameter configuration value, slice parameter usage value, and slice status information associated with the target network slice identifier in the second network element may include: searching for the slice parameter type associated with the second network element corresponding to the first network element and the target analysis identifier in the data source configuration information, and obtaining the slice parameter configuration value, slice parameter usage value, and slice status information corresponding to the slice parameter type in the second network element corresponding to the first network element and the target analysis identifier, thereby obtaining the slice parameter configuration value, slice parameter usage value, and slice status information associated with the target network slice identifier.

[0064] For example, when the first network element is an AN-NSSMF network element or an NSSMF network element, and the target analysis identifier is a slice load, the slice parameter configuration values ​​and slice parameter usage values ​​associated with the target network slice identifier may include: the configuration values ​​and usage values ​​of the number of available uplink and downlink PRBs for the target network slice, the configuration and usage values ​​of the number of registered users for the target network slice, the configuration and usage values ​​of the number of session establishments for the target network slice, the configuration and usage values ​​of uplink and downlink bandwidth, the configuration and actual values ​​of packet loss rate, and the configuration and actual values ​​of latency, etc.

[0065] In an optional implementation, where the slice indicator analysis and prediction results include the analysis and prediction result parameter values ​​of the indicators associated with the target analysis identifier, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the slice parameter configuration value, slice parameter usage value, and slice status information may include: the NWDAF network element inputting the slice parameter configuration value, slice parameter usage value, and slice status information into a pre-established slice analysis model to obtain the analysis and prediction result parameter values ​​of the indicators associated with the target network slice and the target analysis identifier.

[0066] It should be noted that, in the embodiments of this disclosure, the slice analysis model can be a neural network model or a mathematical model. This disclosure does not limit it. It is understood that different slice analysis models can be trained for different analysis dimensions to improve the reliability of the parameter values ​​of the obtained analysis and prediction results.

[0067] In an optional implementation, where the slice indicator analysis and prediction results include slice suggested adjustment values ​​corresponding to the analysis and prediction result parameter values, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the slice parameter configuration values, slice parameter usage values, and slice status information may include: the NWDAF network element inputs the slice parameter configuration values, slice parameter usage values, and slice status information into a pre-established slice analysis model to obtain the analysis and prediction result parameter values ​​associated with the target network slice and the target analysis identifier, and searches for the configuration parameter adjustment magnitude value corresponding to the analysis and prediction result parameter value in the correspondence table between the analysis and prediction result parameter values ​​and the network slice parameter adjustment values ​​to obtain the slice parameter suggested adjustment value. The slice parameter configuration values ​​and slice parameter usage values ​​may include uplink and downlink available PRB quantity configuration values ​​and downlink available PRB quantity usage values, enriching the types of obtained slice parameter configuration values ​​and parameter usage values ​​and improving the accuracy of the obtained analysis and prediction result parameter values.

[0068] It is understood that, in the embodiments of this disclosure, the NWDAF network element can pre-establish the correspondence between the analysis and prediction result parameter values ​​and the slice parameter adjustment range values ​​to obtain the slice configuration update strategy, so as to determine the slice parameter adjustment range of the target network slice. Specifically, the analysis and prediction result parameter values ​​and the slice parameter adjustment range values ​​can be determined based on actual needs, and the embodiments of this disclosure do not limit this.

[0069] In an optional implementation, where the slice indicator analysis and prediction results include slice suggested adjustment values ​​corresponding to the analysis and prediction result parameter values, and the first network element is an NSMF network element, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the slice parameter configuration values, slice parameter usage values, and slice status information for the slice parameter suggested adjustment values ​​in the slice suggested adjustment values ​​may include: determining the first analysis and prediction result parameter values ​​of the target network slice based on the first slice parameter configuration values, the first slice parameter usage values, and the first slice status information associated with the target network slice identifier; determining the second analysis and prediction result parameter values ​​of the target network slice based on the second slice parameter configuration values, the second slice parameter usage values, and the second slice status information associated with the target network slice identifier; and determining the second analysis and prediction result parameter values ​​of the target network slice based on the third slice parameter configuration values, the third slice parameter usage values, and the second slice status information associated with the target network slice identifier; and determining the third analysis and prediction result parameter values ​​of the target network slice based on the third slice parameter configuration values, the third slice parameter usage values, and the second slice status information associated with the target network slice identifier. The third analysis and prediction result parameter value of the target network slice is determined by using the slice parameter usage value and the third slice status information. Then, the slice index analysis and prediction result of the target network slice is determined by using the first analysis and prediction result parameter value, the second analysis and prediction result parameter value, the third analysis and prediction result parameter value, and the slice configuration update strategy. The first slice parameter configuration value, the first slice parameter usage value, and the first slice status information are obtained from the second network element corresponding to the AN-NSSMF network element and the target analysis identifier. The second slice parameter configuration value, the second slice parameter usage value, and the second slice status information are obtained from the second network element corresponding to the CN-NSSMF network element and the target analysis identifier. The third slice parameter configuration value, the third slice parameter usage value, and the third slice status information are obtained from the second network element corresponding to the TN-NSSMF network element and the target analysis identifier. During the configuration update process of the target network slice by the NSMF network element, the slice parameter configuration value, slice parameter usage value and slice status information of the target network slice can be obtained from the data source determined by the three types of NSMF network elements. The analysis and prediction result parameter values ​​and slice adjustment suggestions of the target network slice associated with the three types of NSMF network elements can be determined, which can further improve the accuracy of the configuration update of the target network slice.

[0070] It is understood that the process by which the NWDAF network element determines the first analysis and prediction result parameter value, the second analysis and prediction result parameter value, or the third analysis and prediction result parameter value can refer to the above embodiments. The process by which the NWDAF network element determines the slice index analysis and prediction result of the target network slice based on the slice parameter configuration value, the slice parameter usage value, and the slice status information is not described in detail in this embodiment.

[0071] In one optional implementation, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the first analysis and prediction result parameter value, the second analysis and prediction result parameter value, the third analysis and prediction result parameter value, and the slice configuration update strategy may include: searching for the first slice parameter adjustment value corresponding to the first analysis and prediction result parameter value in the correspondence table between the analysis and prediction result parameter value and the network slice parameter adjustment value, to obtain the first slice parameter suggested adjustment value associated with the target network slice and the AN-NSSMF network element; searching for the second slice parameter adjustment value corresponding to the second analysis and prediction result parameter value, to obtain the second slice parameter suggested adjustment value associated with the target network slice and the CN-NSSMF network element; and searching for the third slice parameter adjustment value corresponding to the third analysis and prediction result parameter value, to obtain the third slice parameter suggested adjustment value associated with the target network slice and the TN-NSSMF network element.

[0072] It should be noted that, in the embodiments of this disclosure, in the scenario where the configuration parameters of the target network slice in each NSMF network element are updated in coordination with the three NSMF network elements, a corresponding correspondence table of analysis and prediction result parameter values ​​and network slice parameter adjustment values ​​can be established for each NSMF network element, so as to determine more accurate slice recommendation adjustment values ​​based on the analysis and prediction result parameter values ​​related to the three NSMF network elements.

[0073] In one optional implementation, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the first analysis and prediction result parameter values, the second analysis and prediction result parameter values, the third analysis and prediction result parameter values, and the slice configuration update strategy may include: searching for a fourth slice parameter adjustment value that combines the analysis and prediction result parameter values ​​with the AN-NSSMF network element in the correspondence table of analysis and prediction result parameter values ​​and network slice parameter adjustment values ​​associated with the AN-NSSMF network element, thereby obtaining the fourth slice parameter suggested adjustment value associated with the target network slice and the AN-NSSMF network element; and then, in the correspondence table of analysis and prediction result parameter values ​​and network slice parameters associated with the CN-NSSMF network element... In the correspondence table of parameter adjustment values, the fifth slice parameter adjustment value corresponding to the parameter value of the combined analysis and prediction results is found to obtain the suggested adjustment value of the fifth slice parameter associated with the target network slice and the CN-NSSMF network element. In the correspondence table of analysis and prediction result parameter values ​​and network slice parameter adjustment values ​​associated with the TN-NSSMF network element, the sixth slice parameter adjustment value corresponding to the parameter value of the combined analysis and prediction results is found to obtain the suggested adjustment value of the fifth slice parameter associated with the target network slice and the TN-NSSMF network element. The parameter values ​​of the combined analysis and prediction results include the parameter values ​​of the first analysis and prediction results, the parameter values ​​of the second analysis and prediction results, and the parameter values ​​of the third analysis and prediction results.

[0074] It should be noted that, in scenarios where the slice indicator analysis and prediction results include the slice suggested adjustment values ​​corresponding to the parameter values ​​of the analysis and prediction results, or in scenarios where the slice indicator analysis and prediction results include the slice suggested adjustment values ​​corresponding to the parameter values ​​of the analysis and prediction results, and the first network element is an NSMF network element, the process by which the NWDAF network element determines the slice indicator analysis and prediction results of the target network slice based on the slice parameter configuration values, slice parameter usage values, and slice status information for the suggested adjustment values ​​of the service quality assurance strategy parameters in the slice suggested adjustment values ​​can refer to the above-described process for determining the suggested adjustment values ​​of the slice parameters in the slice suggested adjustment values. This disclosure embodiment will not elaborate further.

[0075] Step S203: The first network element determines the update result of the target network slice based on the slice index analysis and prediction results, and updates the target network slice based on the update result.

[0076] In this embodiment of the disclosure, the result is either updated slice configuration information or updated service quality assurance policy information. It is understood that the updated slice configuration information is the updated value of the slice parameters, and the updated service quality assurance policy information can be the updated value of the quality assurance policy parameters.

[0077] In an optional implementation, before the first network element determines the update result of the target network slice based on the slice indicator analysis and prediction results, if the first network element determines that the target network slice is an updatable network slice based on the slice indicator analysis and prediction results and the configuration strategy of the target network slice, it determines the adjustment result of the target network slice based on the slice indicator analysis and prediction results, wherein the adjustment result is also the update result. Before updating the target network slice, the feasibility of updating the target network slice can be judged based on the analysis results and configuration strategy of the target network slice, to further ensure the rationality and reliability of the configuration update of the target network slice.

[0078] It should be noted that, in this embodiment, the configuration strategy for the target network slice may include the resource requirements and slice priority of the target network slice. In an optional implementation, the process by which the first network element determines whether the target network slice is an updatable network slice based on the slice indicator analysis and prediction results and the configuration strategy of the target network slice may include: finding the correspondence between the resource requirements and resource requirement levels of the target network slice to obtain the resource requirement level of the target network slice; if the resource requirement level of the target network slice is determined to be high, then if the analysis and prediction result parameter values ​​in the slice indicator analysis and prediction results are greater than the first analysis result parameter threshold corresponding to the high resource requirement level, the target network slice is determined to be an updatable network slice; or, if the slice suggested adjustment value in the slice indicator analysis and prediction results is less than the first slice parameter suggested adjustment threshold corresponding to the high resource requirement level, the target network slice is determined to be an updatable network slice. The first analysis result parameter threshold and the first slice parameter suggested adjustment threshold can be determined based on actual needs, and this embodiment does not limit them. For example, when the target analysis identifies the slice load, the threshold value of the first analysis result parameter corresponding to the high resource demand level can be: the slice load threshold is 60%. That is, when the analysis and prediction result parameter value of the slice load in the slice index analysis and prediction results of the target network slice is greater than 60%, the target slice can be determined as an updatable network slice.

[0079] In one optional implementation, the process by which the first network element determines whether a target network slice is an updatable network slice based on the slice index analysis and prediction results and the configuration strategy of the target network slice may include: if the slice priority of the target network slice is determined to be high, then if the analysis and prediction result parameter values ​​in the slice index analysis and prediction results are greater than the second analysis result parameter threshold corresponding to high slice priority, the target network slice is determined to be an updatable network slice; or, if the slice suggestion adjustment value in the slice index analysis and prediction results is less than the second slice parameter suggestion adjustment threshold corresponding to high slice priority, the target network slice is determined to be an updatable network slice. The second analysis result parameter threshold and the second slice parameter suggestion adjustment threshold can be determined based on actual needs, and this embodiment does not limit this.

[0080] In one optional implementation, the first network element is an NSMF network element or an NSSMF network element, and the slice indicator analysis and prediction result is the analysis and prediction result parameter value. The process by which the first network element determines the update result of the target network slice based on the slice indicator analysis and prediction result may include: searching for the target configuration parameter adjustment range value or target adjustment threshold value corresponding to the analysis and prediction result parameter value in the correspondence table between the network slice indicator analysis and prediction result and the network slice parameter adjustment rule; then, determining the updated slice configuration information of the target network slice based on the range of the target configuration parameter adjustment range value or the target adjustment threshold value and the current configuration parameter value of the target network slice. This allows the first network element, after obtaining the analysis and prediction result parameter value of the indicator associated with the target analysis identifier, to search for the target configuration parameter adjustment range value of the target network slice under the condition of the analysis and prediction result parameter value in the correspondence table between the network slice indicator analysis and prediction result and the network slice parameter adjustment rule to determine the updated slice configuration information. This enables automated updating of the configuration parameters of the target network slice based on the analysis and prediction result parameter value associated with the target analysis identifier.

[0081] The process by which the first network element determines the updated slice configuration information of the target network slice based on the target configuration parameter adjustment range or target adjustment threshold value and the current configuration parameter value of the target network slice may include: if the target configuration parameter adjustment range is a decrease in the configuration parameter, the difference between the current configuration parameter value and the target configuration parameter adjustment range can be determined as the updated slice configuration information of the target network slice; or, if the target configuration parameter adjustment range is an increase in the configuration parameter, the sum of the current configuration parameter value and the target configuration parameter adjustment range can be determined as the updated slice configuration information of the target network slice; or, the current configuration parameter value of the target network slice is randomly adjusted, and if the randomly adjusted configuration parameter value is determined to be within the target adjustment threshold value range, the randomly adjusted configuration parameter value is determined as the updated slice configuration information of the target network slice.

[0082] In one optional implementation, the first network element is an NSMF network element or an NSSMF network element, and the slice index analysis and prediction result is the slice parameter suggested adjustment value in the slice suggested adjustment value. The process of determining the update result of the target network slice based on the slice index analysis and prediction result may include: searching for the target configuration parameter adjustment range value or target adjustment threshold value corresponding to the analysis and prediction result parameter value in the correspondence table between the network slice index analysis and prediction result and the network slice parameter adjustment rule; then, if the slice parameter suggested adjustment value meets the range of the target configuration parameter adjustment range value or the target adjustment threshold value, the updated slice configuration information of the target network slice is determined based on the slice parameter suggested adjustment value and the current configuration parameter value of the target network slice; wherein, the slice parameter suggested adjustment value meeting the range of the target configuration parameter adjustment range value or the target adjustment threshold value means that the slice parameter suggested adjustment value is less than the target configuration parameter adjustment range value, or that the slice parameter suggested adjustment value is within the range of the target adjustment threshold value. After obtaining the suggested adjustment value of the slice parameters corresponding to the target analysis identifier, the first network element can look up the target configuration parameter adjustment range value for the target network slice under the parameter values ​​of the analysis and prediction results in the correspondence table between the network slice index analysis and prediction results and the network slice parameter adjustment rules. If it is determined that the suggested adjustment value of the slice parameters is less than or equal to the target configuration parameter adjustment range value, the NWDAF network element determines that the suggested adjustment value of the slice parameters is a reasonable value. Based on the suggested adjustment value of the slice parameters, the updated slice configuration information is determined. This enables the automatic updating of the configuration parameters of the target network slice based on the suggested adjustment value of the slice parameters.

[0083] It should be noted that when the first network element is an NSMF network element, the NSMF network element can request an update of information related to the target network slice from at least one of the AN-NSSMF network elements, CN-NSSMF network elements, and TN-NSSMF network elements.

[0084] In an optional implementation, when the first network element is an NSMF network element and it is necessary to coordinate with three NSMF network elements to update the target network slice information, the slice indicator analysis and prediction results received by the first network element may include: first analysis and prediction result parameter values, second analysis and prediction result parameter values, and third analysis and prediction result parameter values. The process by which the first network element determines the update result of the target network slice based on the slice indicator analysis and prediction results may include: when the NSMF network element determines that the target network slice in the AN-NSSMF network element is an updatable network slice based on the first analysis and prediction result parameter values ​​and the configuration strategy of the target network slice, it determines the update result based on the first analysis and prediction result parameter values, and then... (The sentence is incomplete and ends abruptly). The adjustment range of the target configuration parameters of the target network slice associated with the SSMF network element; and, if the target network slice in the CN-NSSMF network element is determined to be an updatable network slice based on the parameter values ​​of the second analysis and prediction results and the configuration strategy of the target network slice, the adjustment range of the target configuration parameters of the target network slice associated with the CN-NSSMF network element is determined based on the parameter values ​​of the second analysis and prediction results; and, if the target network slice in the TN-NSSMF network element is determined to be an updatable network slice based on the parameter values ​​of the third analysis and prediction results and the configuration strategy of the target network slice, the adjustment range of the target configuration parameters of the target network slice associated with the TN-NSSMF network element is determined based on the parameter values ​​of the third analysis and prediction results.

[0085] Furthermore, the process of the first network element updating the target network slice based on the update result may include: sending the target configuration parameter adjustment value of the target network slice associated with the AN-NSSMF network element to the AN-NSSMF network element, so that the AN-NSSMF network element updates the configuration of the target network slice according to the determined updated slice configuration information; sending the target configuration parameter adjustment value of the target network slice associated with the CN-NSSMF network element to the CN-NSSMF network element, so that the CN-NSSMF network element updates the configuration of the target network slice according to the determined updated slice configuration information; and sending the target configuration parameter adjustment value of the target network slice associated with the TN-NSSMF network element to the TN-NSSMF network element, so that the TN-NSSMF network element updates the configuration of the target network slice according to the determined updated slice configuration information.

[0086] Similarly, when the first network element is an NSMF network element and it needs to coordinate with three NSMF network elements to update the target network slice information, the slice indicator analysis and prediction results received by the first network element include: the first slice parameter suggested adjustment value corresponding to the first analysis and prediction result parameter value associated with the AN-NSSMF network element, the second slice parameter suggested adjustment value corresponding to the second analysis and prediction result parameter value associated with the CN-NSSMF network element, and the third slice parameter suggested adjustment value corresponding to the third analysis and prediction result parameter value associated with the TN-NSSMF network element. The process of the first network element updating the target network slice based on the update results may include: when it is determined that the target network slice in the AN-NSSMF network element is an updatable network slice according to the first analysis and prediction result parameter value and the configuration strategy of the target network slice, and when it is determined that the first slice parameter suggested adjustment value is less than or equal to the target configuration parameter adjustment range value corresponding to the first analysis and prediction result parameter value, the first slice parameter suggested adjustment value is sent to the AN-NSSMF network element, so that the AN-NSSMF network element updates the target network slice according to the first analysis and prediction result parameter value. The configuration of the target network slice is updated by adjusting the suggested adjustment values ​​of all slice parameters. If, based on the second analysis and prediction result parameter values ​​and the target network slice configuration strategy, the target network slice in the CN-NSSMF network element is determined to be an updatable network slice, and the suggested adjustment value of the second slice parameter is less than or equal to the target configuration parameter adjustment range corresponding to the second analysis and prediction result parameter values, the suggested adjustment value of the second slice parameter is sent to the CN-NSSMF network element so that the CN-NSSMF network element updates the configuration of the target network slice according to the suggested adjustment value of the second slice parameter. Furthermore, if, based on the third analysis and prediction result parameter values ​​and the target network slice configuration strategy, the target network slice in the TN-NSSMF network element is determined to be an updatable network slice, and the suggested adjustment value of the third slice parameter is less than or equal to the target configuration parameter adjustment range corresponding to the third analysis and prediction result parameter values, the suggested adjustment value of the third slice parameter is sent to the TN-NSSMF network element so that the TN-NSSMF network element updates the configuration of the target network slice according to the suggested adjustment value of the third slice parameter.

[0087] In one optional implementation, the first network element is an NF network element, and the slice indicator analysis and prediction result is the analysis and prediction result parameter value. The process by which the first network element determines the updated result of the target network slice based on the slice indicator analysis and prediction result may include: searching for the target service quality assurance policy parameter adjustment value corresponding to the analysis and prediction result parameter value in the network slice indicator analysis and prediction result and the service quality assurance policy parameter adjustment rules; then, determining the target service quality assurance policy parameter adjustment value as the updated service quality assurance policy information of the target network slice. This allows the first network element, after obtaining the analysis and prediction result parameter value associated with the target analysis identifier, to search for the target service quality assurance policy parameter adjustment value for the target network slice under the condition of the analysis and prediction result parameter value in the network slice indicator analysis and prediction result and the service quality assurance policy parameter adjustment rules, thereby determining the updated service quality assurance policy information. This enables automated updating of the service assurance parameters of the target network slice based on the analysis and prediction result parameter value associated with the target analysis identifier.

[0088] In one optional implementation, the first network element is an NF network element, and the slice indicator analysis and prediction result is the suggested adjustment value of the service quality assurance strategy parameter in the slice suggested adjustment value. The process of determining the updated result of the target network slice based on the slice indicator analysis and prediction result may include: searching for the target service quality assurance strategy parameter adjustment value or target threshold value corresponding to the parameter value of the analysis and prediction result in the network slice indicator analysis and prediction result and the service quality assurance strategy parameter adjustment rule; wherein, if the suggested adjustment value of the service quality assurance strategy parameter meets the range of the target service quality assurance strategy parameter adjustment value or target threshold value, then the suggested adjustment value of the service quality assurance strategy parameter is determined as the updated service quality assurance strategy information of the target network slice. After obtaining the suggested adjustment value of the service quality assurance strategy parameter corresponding to the target analysis identifier, the first network element can search for the target service quality assurance strategy parameter adjustment value for the target network slice under the parameter values ​​of the analysis and prediction results in the network slice indicator analysis and prediction results and the service quality assurance strategy parameter adjustment rules. If it is determined that the suggested adjustment value of the service quality assurance strategy parameter is less than or equal to the target service quality assurance strategy parameter adjustment threshold, the suggested adjustment value of the service quality assurance strategy parameter determined by the NWDAF network element is determined to be a reasonable value. Based on the suggested adjustment value of the service quality assurance strategy parameter, the updated service quality assurance strategy information is determined. This enables automated updating of the target network slice based on the suggested adjustment value of the service quality assurance strategy parameter.
