CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority of the Chinese patent application filed on August 31, 2020 with the application number of 202010897754.7 and titled "A method and device for subscribing network performance data", the entire contents of which are incorporated herein by reference Applying.

technical field

The embodiments of the present application relate to the technical field of network management, and in particular, to a method and apparatus for subscribing to network performance data.

Background technique

In the process of intent implementation, the experiential networked intelligence system (ENI System) needs to periodically obtain network performance data to support the execution or maintenance of intent. In order to cooperate with the execution and maintenance of intent, ENI System initiates a subscription process for each intent (Intent Policy). Illustratively, a network performance data subscription request is sent to an infrastructure (eg, an assisted system) through an external interface (Iinf-eni-cmd) and from the infrastructure through an external interface (Iinf-eni-dat) (eg Assisted System) Periodically obtain network measurement reports. This network measurement report includes network performance data subscribed by the ENI System.

Among them, the name list (key performance indicator list, KPIList) of the network performance data required by each intent includes two types of lists {S1, S2}, and S1 and S2 are the name sets of the two network performance data. Among them, S1 is used to judge or predict whether the intended goal is achieved or satisfied. S2 is used to determine the executable command that matches the intent in the current scene. Among them, the intent includes four different states. The four states are active (active) state, inactive (inactive) state, conflicted (conflicted) state, and sleep (sleep) state. The requirements for network performance data corresponding to each state are different.

When the intent is executed for the first time, the ENI system can send a network performance data subscription request to the auxiliary system, which is used to request S1 and S2, and as the state of the intent changes, the network performance data subscribed by the ENI System does not change. Therefore, This will result in redundant reporting of network performance data and waste of transmission resources.

detailed description

The following briefly introduces the ENI architecture involved in the embodiments of the present application.

The ENI architecture includes a total of 10 functional modules, which are divided into four categories: input functional modules, output functional modules, analysis functional modules, and decision-making functional modules, as shown in Figure 1.

Input class function module: (that is, data reading and normalization (Data Ingestion and Normalisation) module) is responsible for receiving data from external systems and normalizing data. Among them, the data reading and normalization modules are two modules.

Output class function module: (ie, the output generation and denormalisation module) is responsible for converting the internal commands of the system into a format that can be processed by the external system and sending it to the external system.

Analysis function module: responsible for perceiving and analyzing the existing network state and predicting the future network state. The analysis function modules include the Knowledge Management module, the Context Awareness module, and the Cognition Management module.

Among them, the knowledge management module is mainly responsible for managing all knowledge within the scope of ENI, completing the identification of the strategy type of the intention and the storage of the knowledge related to the intention.

The context-aware module is mainly responsible for acquiring the status and environment information of the Assisted System, for example, for acquiring the performance data of network elements (such as base stations (gNodeB)). The Assisted System may be a radio access network element or a core network element (such as a user plane function (UPF)).

The cognitive management module is mainly responsible for the understanding of network data and the cognition of network status in the process of intention maintenance.

Decision-making function module: On the basis of the perception of network state, new strategies are generated and arranged according to the intention, and the operation command is sent to the output function module. Decision-making functional modules include Situation Awareness, Policy Management, and Model-driven Engineering. Alternatively, the decision-making functional modules include a Situation Awareness module, a Policy Management module, a Model-driven Engineering module, and an Intent Translation module.

The context awareness module is mainly responsible for perceiving the impact of the recommendations or commands issued by the ENI system on the Assisted System. For example, it is used to perceive the achievement of an intended goal.

The model-driven engineering module mainly assists in transforming intent knowledge and contextual information into a format that can be recognized by the policy management module through a model-driven approach.

The policy management module is mainly responsible for generating a policy to ensure the achievement of the intent based on the intent knowledge and context information, and delivering it to the Assisted System.

The intent translation module is mainly responsible for the lexical parsing of intent expressions, and obtains intent-related knowledge from the knowledge management module according to the content of the intent expressions.

It can be understood that there are currently two options for implementing the intent translation function in the ENI architecture: 1) function enhancement based on a policy management module and 2) an independent function module of the architecture.

Referring to FIG. 2 , the above-mentioned ENI system can be deployed in wireless network management network elements of various layers, as shown in Examples 1 to 4 below.

Example 1: The ENI system is deployed on the Business Support Systems (BSS), and the ENI system receives the communication service consumer intent (Intent-CSC) of the Communication Service Customer (CSC) and translates it into Communication service provider intent (Intent-CSP), issued to the ENI system on the network management system (NMS).

Example 2: The ENI system is deployed on the NMS, and the ENI system receives the Intent-CSP intent from the BSS. If the intent describes the operation and maintenance requirements of the NMS itself, the intent is executed by calling local data analysis and control operations; if the intent describes the operation and maintenance requirements of the underlying EMS or network elements, the ENI system decomposes the Intent-CSP into network The manager's intent (Intent-NOP) is sent to the corresponding element management system (EMS).

Example 3: ENI system is deployed on EMS, ENI system receives Intent-NOP intent from NMS. If the intent describes the operation and maintenance requirements of the EMS itself, call the local data analysis and control operations to execute the intent; if the intent describes the operation and maintenance requirements, it is a network equipment (NE) with an intent system, for example: a centralized management type The base station group (ClusterRAN) or cluster sends the sub-intent to the NE.

Example 4: The ENI system is deployed on the NE (such as Cluster), the ENI system receives the intent from the EMS from the intent-based southbound interface, and then translates it into its own operation and maintenance operations, and calls the local one through the policy management module. Data analysis and governance operations to enforce and maintain intent.

A brief introduction to intents and intent states follows.

Intent is a declarative strategy. The intent expression only contains the description of the purpose, and the specific implementation method of the intent is obtained and executed by the system by parsing and translating those lexical grammars. For example, an intent expression can carry a target value (eg, delay <5ms), and the system can select different strategies from the set of available execution strategies determined according to the intent according to different target values. Exemplarily, intent expressions include actions and objects (also known as operation objects), where an action refers to a network operation that is abstracted and simplified according to intent requirements, including an action name (intent driven action name, IDA name) and a series of Related properties (IDA Properties), the object refers to the management object information provided according to the intent requirements, including an object name (intent driven object name, IDO Name) and a series of properties (IDO Properties) used to identify the object. The target value of the intent can be contained in the action or contained in the object. Alternatively, intent expressions include actions, objects, and target values. For example, the intention is to optimize the downlink rate of the cell, where the action is "optimize", the object is "cell", and the target value is the specific value of the downlink rate of the cell.

After the high-level intent-driven network (H-IDN) receives the intent from the manager or higher level (level) intent-driven network, it decomposes the intent and sends it to the low-level intent-driven network (low-level intent-driven network). -level intent-driven networking, L-IDN) to send decomposed sub-intents. Among them, the operation objects (for example, network elements) corresponding to the intention are managed by different L-IDNs. After the L-IDN receives the sub-intent, the L-IDN executes the sub-intent and sends feedback information to the H-IDN. The H-IDN can determine whether the intent is achieved according to the feedback information reported by the L-IDN. If the intent is not achieved, the intent is re-decomposed and the re-decomposed sub-intent is delivered. From the H-IDN sending the sub-intent to receiving the feedback information reported by the L-IDN is called an intent negotiation. Among them, the achievement of the intent is equivalent to the achievement of the sub-intent corresponding to each L-IDN. Among them, H-IDN can provide intent management functions with a higher level of abstraction, and can deliver intents with a lower level of abstraction to the lower-level intent subsystem. H-IDN can be developed and deployed as a stand-alone software system, or enhanced on the basis of an operator's NMS. The L-IDN can provide an intent management function with a lower level of abstraction, and can issue an intent with a lower level of abstraction to a lower-level intent subsystem, or issue management commands to network elements. The functional modules in L-IDN can be developed and deployed as independent software systems, or enhanced on the basis of EMS of network equipment.

The intent includes four states, and the requirements for network performance data in each state are different, and the requirements for the reporting period of network performance data are also different.

1) The inactive state refers to the initial state of the intent, indicating that the diagram has not yet been implemented.

2) The active state refers to the state in which the intent has been translated and is being implemented.

3) The conflicted state refers to the state in which the implementation of the intent is suspended by the system due to conflict with other intents. Among them, if the policies corresponding to the two intents respectively include mutually exclusive operations on the same parameter and/or attribute of the same network element, the two intents are said to conflict with each other.

4) The sleep state refers to the state in which the intent is set because the goal of the intent has not been achieved for a long time during the process of maintaining the intent. In the sleep state, the system stops maintaining the intent, but predicts the achievement of the intent's goal. Once the predicted goal of the intent is likely to be reached, the intent is set to the active state.

Further, as shown in FIG. 3 , the network performance data requirements for the above four states are as follows:

1) Inactive state: Network performance data is not required.

2) Active state: S1 and S2 are required, according to S1 to judge whether the intent target is satisfied, according to S2 to judge the current scene, and to match the appropriate executable command.

3) Conflicted state: S2 is required, the current scene is judged according to S2, and the appropriate executable command is matched.

4) Sleep state: S1 is required, and whether the intended goal is likely to be achieved according to S1.

In addition, when the intent is executed for the first time, the ENI system sends a network performance data subscription request (for example, sending a network performance data subscription request to the Assisted System), where the network performance data subscription request is used to request S1 and S2, and the reporting of network performance data The period (reportPeriod) is a preset minimum value (for example, reporting with the minimum capability of the Assisted System). In addition, within an intent life cycle, the reporting cycle and the name list (ie, S1 and S2) of the network performance data remain unchanged.

As shown in FIG. 4 , it is one of the specific flowcharts for the ENI system to subscribe to the network performance data after receiving the intention.

Step 1: The intent translation module and the knowledge management module complete the intent translation.

Step 2: The intent translation module sends an Intent Execution Request message to the policy management module.

Step 3: The policy management module sends an Intent Fulfillment State Retrieve Request message to the state awareness module.

Wherein, the policy management module also determines S1 and S2 according to the determination intention execution request message. Wherein, the intent-satisfied state update request message includes S1 and S2.

Step 4: The context awareness module sends a network status update (Network Status Retrieve Request) message to the cognitive management module.

Wherein, the network status update message includes S1 and S2.

Step 5: The cognitive management module sends a create measurement task request (createMeasJob) to the output generation and denormalization module.

The create measurement task request includes S1 and S2.

Step 6: Output generation and denormalization Send a create measurement task request to the auxiliary system.

Step 7: The auxiliary system sends reporting performance data (reportStreamData) to the ENI system.

Step 8: The data reading and normalization module sends the reporting performance data to the cognitive management module.

The reported performance data includes performance data corresponding to S1 and S2.

Step 9: The cognitive management module sends a Network Status Retrieve Response message to the context awareness module.

The network status update reply includes performance data corresponding to S1 and S2.

Step 10: The context perception module determines whether the intention is satisfied.

Specifically, the context perception module determines whether the intention is satisfied according to the performance data corresponding to S1 and S2.

Step 11: The context awareness module sends an intent-satisfied state update reply message to the policy management module.

Specifically, the intent-satisfied state update reply message is used to notify the policy management module whether the intent is satisfied.

It can be seen from the above that when the intent is in different states, the requirements for network performance data are different. In Active state, {S1, S2} is required, in Conflicted state only S2 is required, in Sleep state only S1 is required, and in Inactive state no network performance data is required. At the same time, when the intentions are in different states, the requirements for the reporting period of the network performance data are also different. For example, a shorter reporting period needs to be used in the Active state, while a longer reporting period can be used in other states. When the ENI system issues a subscription request for network performance data, the ENI system always issues a subscription request for network performance data according to the requirements of the active state. The name list (for example, S1 and S2) remains unchanged, which leads to redundant network performance data transmission, which is easy to cause waste of resources, and frequently receives network performance data. Goal attainment calculations or predictions.

It can be understood that, in this embodiment of the present application, the first set, the second set, the third set and the fourth set are all used to indicate a list of network performance data, and the auxiliary system can determine the network to be reported according to the corresponding set. performance data. The first set, the second set, the third set and the fourth set may also be referred to as the first list, the second list, the third list and the fourth list respectively, in addition, the first set, the second set, the third set and the The fourth set may also be named by other names, which are not limited in this embodiment of the present application. The list of network performance data may also be referred to as a set of names of network performance data, or a list of types of network performance data, etc., which is not limited in this embodiment of the present application. Exemplarily, the first set may indicate the names of a set of network performance data. For example, if the first set includes names of network performance data such as throughput rate and network speed, the auxiliary system may report the name of the auxiliary system according to the first set. Network performance data such as throughput and the network speed of this auxiliary system.

Based on this, an embodiment of the present application provides a network performance data subscription method. As shown in FIG. 5 , the method includes:

S501: The policy management function module determines a first set, where the first set is used to refer to a list of network performance data corresponding to the first state of the schematic diagram.

S502: When the state of the intention is switched from the first state to the second state, the policy management function module sends the first information to the output function module.

Wherein, in some embodiments, the policy management function module determines that the state of intent is switched from the first state to the second state. When the states of the intent are respectively activated, inactive, conflicting, and sleeping, the state of the intent is switched from the first state to the second state, which may include but are not limited to the following possible situations: The state switches to inactive, or the intent's state switches from inactive to active, or the intent's state switches from active to sleep, or the intent's state switches from sleep to active, or the intent The state of an intent switches from an active state to a conflicting state, or the intent's state switches from a conflicting state to an active state.

The first information includes a second state or a second set, the second set is used to indicate a list of network performance data corresponding to the second state, the second state is used to determine the second set, and the first set is different from the second set . Exemplarily, the first information includes the second state, or the first information includes the second set, or the first information includes the second state and the second set.

In some embodiments, when the first information includes the second state, the policy management function module further sends the corresponding relationship between the second state and the second set to the output function module. After the output function module receives the first information from the policy management function module, the output function module determines the second set according to the second state. Further, the output function module sends the second set to the auxiliary system. It can be understood that, the policy management function module can also send the corresponding relationship between each state and the set to which it corresponds to the output function module.

In some embodiments, when the first information includes the second state, after the output function module receives the first information from the policy management function module, the output function module sends the second state to the auxiliary system.

In some embodiments, when the first information includes the second set, the output function module sends the second set to the auxiliary system after receiving the first information from the policy management function module.

In addition, the policy management function module may send the first information to the output function module through the first function module. The first functional module includes at least one of a cognitive management functional module, a context-aware functional module, a context-aware functional module, a model-driven engineering functional module, and a knowledge management functional module.

Exemplarily, the policy management function module may send the first information to the output function module through the context-aware function module. Alternatively, the policy management function module may send the first information to the cognitive management function module through the context awareness function module, and then the cognitive management function module sends the first information to the output function module.

It can be understood that, as can be seen from S501, when the state of the intention changes, the policy management function module is triggered to send the first information to the output function module, and the first information is used to update the network performance data to be subscribed to, that is, the network is not subscribed for the first time. performance data. A possible implementation of the first subscription to network performance data is described below. The policy management function module receives the intent. Exemplarily, the intent translation function module sends an intent execution request to the policy management function module. The policy management functional module determines the third set and the fourth set according to the intent translation result in the intent execution request, the policy management functional module sends second information to the output functional module, the second information is used to subscribe to the network performance data, and the second information includes the first The third set and the fourth set. Wherein the third set indicates a list of network performance data (eg S1 ) required to determine whether the goal of the intent is achieved, and the fourth set indicates a list of network performance data (eg S2 ) required for executable commands matching the intent. At this time, the state of the intent is the active state, and the second information may further include a reporting period corresponding to the state of the intent being the active state. It can be understood that the reporting period corresponding to the state of the intent being the active state may be carried in the second information, or may be sent separately, or sent in other information.

In addition, the second information may further include the correspondence between the state of the intention and the third set and the fourth set. Exemplarily, the activated state corresponds to the third set and the fourth set, the sleep state corresponds to the third set, the conflict state corresponds to the fourth set, and the deactivated state corresponds to an empty set. Further, when the intended state in S501 is switched to the sleep state, the first information includes the sleep state and/or a list of network performance data corresponding to the sleep state.

Since the second information includes the third set and the fourth set, and the list of network performance data corresponding to the conflict state is the fourth set, the first information may include the conflict state and/or the fourth set.

It can be understood that, the above embodiments are only described by taking the list of network performance data including the third set and the fourth set (for example, S1 and S2) as an example. In addition, with the development and evolution of technology, the list of network performance data also includes Other collections can be included. Similarly, the state of the intent can also include other states. Therefore, the methods provided by the embodiments of the present application can be used whenever the network performance data that needs to be subscribed for states involving different intentions is different.

S603: The second network element receives the first information from the first network element, and the second network element sends third information to the first network element, where the third information includes network performance data corresponding to the second set.

In some embodiments, when the first information includes the second state, the first network element further sends a correspondence between the second state and the second set to the second network element.

It is not the first time that the network element subscribes the network performance data to the second network element.

The following describes a possible implementation manner in which the first network element subscribes the network performance data to the second network element for the first time. In some embodiments, when the first network element receives the intent, the first network element determines the third set and the fourth set based on the intent. Wherein the third set indicates a list of network performance data (eg S1 ) required to determine whether the goal of the intent is achieved, and the fourth set indicates a list of network performance data (eg S2 ) required for executable commands matching the intent. The first network element sends second information to the second network element, where the second information is used by the first network element to subscribe to the network performance data for the purpose of subscribing to the network performance data for the first time, wherein the second information includes the third set and the fourth set . At this time, the state of the intent is the active state, and in addition, the second information may further include a reporting period corresponding to the state of the intent being the active state. It can be understood that the reporting period corresponding to the state of the intent being the active state may be carried in the second information, or may be sent separately, or carried in other information and sent.

Correspondingly, when the second network element receives the second information from the first network element, the second network element sends fourth information to the first network element, where the fourth information includes the network performance data corresponding to the third set and the fourth information. Collect the corresponding network performance data. In addition, when the second network element learns that the state of the intention is a reporting period corresponding to the active state, the second network element sends the fourth information to the first system according to the reporting period. In addition, the second information may further include the correspondence between the state of the intention and the third set and the fourth set. Exemplarily, the activated state corresponds to the third set and the fourth set, the sleep state corresponds to the third set, the conflict state corresponds to the fourth set, and the deactivated state corresponds to an empty set.

Further, when the intended state in S601 is switched to the sleep state, the first network element sends first information to the second network element, where the first information includes the sleep state and/or a list of network performance data corresponding to the sleep state. Since the first network element subscribes to the network performance data corresponding to the third set and the fourth set respectively when the first network element subscribes the network performance data to the second network element for the first time (that is, the second information includes the third set and the fourth set ), and the list of network performance data corresponding to the sleep state is the third set, the first information may include the sleep state and/or the third set.

Same as above, when the intended state in S601 is switched to the conflict state, the first network element sends first information to the second network element, the first information including the conflict state and/or the list of network performance data corresponding to the conflict state. Since the first network element subscribes to the network performance data corresponding to the third set and the fourth set respectively when the first network element subscribes the network performance data to the second network element for the first time (that is, the second information includes the third set and the fourth set ), and the list of network performance data corresponding to the conflict state is the fourth set, the first information may include the conflict state and/or the fourth set.

The same as above, when the intended state in S601 is switched to the deactivated state, the first network element sends first information to the second network element at this time, and the first information includes the deactivated state and/or the network performance data corresponding to the deactivated state. list. The list of network performance data corresponding to the deactivated state is empty.

It can be understood that, the above embodiments are only described by taking the list of network performance data including the third set and the fourth set (for example, S1 and S2) as an example. In addition, with the development and evolution of technology, the list of network performance data also includes Other collections can be included. Similarly, the state of the intent can also include other states. Therefore, the methods provided by the embodiments of the present application can be used whenever the network performance data that needs to be subscribed for states involving different intentions are different.

Using the above method, when the intention is in different states, the subscribed performance data is updated according to the state of the intention, the collection type of the performance data of the auxiliary system can be adjusted, the reporting period can be adjusted, and transmission resources and computing resources can be saved.

Specific implementations of the embodiments of the present application are described below with reference to specific examples:

Example 1 is the specific process of subscribing performance data for the first time, as shown in Figure 7.

Step 1: The intent translation module completes the intent translation.

Step 2: The intent translation module sends an intent execution message to the policy management module, which may include but is not limited to the following information elements: policy identifier (policyId), entity identifier format list (entityId_FormatList{<entityId,format>}, intent description ( intentInstruction){<executionCondition,Instruction>}, fulfillmentCriterion.

Step 3: The policy management module sends a performance data subscription (performanceDataSubscription) message to the first functional module.

Specifically, the policy management module determines KPIList_S1 and KPIList_S2 according to the intent description and satisfaction criteria in the intent execution message, wherein the performance data subscription message includes (KPIList_S1, KPIList_S2, report Period), and KPIList_S1 indicates whether the intent target satisfies all requirements. The name set of the required performance data, KPIList_S2 indicates the name set of the performance data required to match the intent executable command, and reportPeriod refers to the reporting period of the schematic diagram.

The first functional module may include at least one of a cognitive management functional module, a context-aware functional module, a context-aware functional module, a model-driven engineering functional module, and a knowledge management functional module. The policy management module may send a performance data subscription message to the output generation and denormalization module through the at least one first functional module.

Step 4: The first functional module sends a performance data subscription message to the output generation and denormalization module, and the performance data subscription message includes (KPIList_S1, KPIList_S2, reportPeriod).

In addition, it can be understood that the policy management module can also send performance data subscription messages directly to the output generation and denormalization module.

It can be understood that steps 3 and 4 can also be replaced by the policy management module sending a performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to send the output generation and denormalization module through the first functional module. Performance data subscription messages, instead send performance data subscription messages directly to the output generation and denormalization modules.

Step 5: The output generation and denormalization module sends a performance data subscription message to the auxiliary system.

Step 6: The auxiliary system sends performance data to the ENI system.

The performance data includes performance data corresponding to KPIList_S1 and performance data corresponding to KPIList_S2.

Specifically, the data reading and normalization module in the ENI system receives performance data from auxiliary systems.

Alternatively, the ENI system obtains performance data periodically.

Step 7: The data reading and normalization module sends performance data to the first functional module.

Exemplarily, in step 3, the policy management module may send a performance data subscription message to the output generation and denormalization module through the context awareness module. Meanwhile, in step 7, the data reading and normalization module may send performance data to the policy management function module through the context awareness module.

Exemplarily, in step 3, the policy management function module may send the performance data subscription message to the cognitive management module through the context awareness module, and then the cognitive management module sends the performance data subscription message to the output generation and denormalization module. Meanwhile, in step 7, the data reading and normalization module may send performance data to the context-aware module through the cognitive management function, and then the context-aware function module sends the performance data to the policy management function module.

Step 8: The first functional module sends performance data to the policy management module.

It can be understood that the first functional module can also send satisfaction information to the policy management module at the same time, where the satisfaction information is used to indicate whether the schematic diagram is satisfied.

Compared with one cell for the performance data name set required by the intent, in Example 1, the performance data name set required by the intent is divided into two cells, and each cell represents a different function of the performance data, which can be implemented in different Separate usage in intent state.

In addition, compared with the default period for the reporting period of performance data, in Example 1, the policy management module can modify the reporting period according to the state of the intention.

Example 2 is one of the specific processes for updating subscription performance data, as shown in FIG. 8 .

Step 1: The policy management module determines that the intent has not been satisfied within the specified time.

Step 2: The policy management module stops the intention maintenance, that is, stops the operation of adjusting the executable policy of the intention according to the network state.

Step 3: The policy management module sends an update performance data subscription (updatePerformanceDataSubscription) message to the first functional module, where the update performance data subscription message includes the reporting period and the status of the intent or a set of network performance data names corresponding to the reporting period and the status of the intent.

The intent state is the sleep state, the network performance data name set corresponding to the intent state is the network performance data name set corresponding to the sleep state, namely KPIList_S1, and the reporting period is the reporting period corresponding to the sleep state.

In addition, when the update performance data subscription request includes the reporting period and the state of the intent, the first functional module may further determine the set of network performance data names corresponding to the state of the intent according to the state of the intent.

Step 4: The first functional module sends an Intent Fulfillment Prediction Acknowledge message to the policy management module, and the Intent Fulfillment Prediction Acknowledge message is used to indicate the start of predicting the Intent Fulfillment Prediction Acknowledge.

Exemplarily, the first functional module here may be a context awareness module and/or a context awareness module.

Step 5: The first functional module sends an update performance data message to the output generation and denormalization module.

It can be understood that step 3 and step 5 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 6: The output generation and denormalization module sends an update performance data message to the auxiliary system.

Step 7: The auxiliary system sends performance data to the ENI system.

The performance data includes performance data corresponding to KPIList_S1 (denoted as KPI_ValueList_S1).

Step 8: The data reading and normalization module sends performance data to the first functional module.

Step 9: The first functional module predicts the intention satisfaction situation according to the performance data.

Step 10: When the predicted intent target may be met (for example, when the probability of the intent target being met is greater than a specified threshold), the first functional module sends an intent fulfillment prediction notification (Intent Fulfillment Prediction Notification) message to the policy management module, the message Indicates that the schematic can be awakened.

Otherwise, the first functional module continues to predict the intention satisfaction situation according to the performance data received each time.

Step 11: The policy management module sends an update performance data subscription message to the first functional module. In this case, the update performance data subscription message includes the status of the reporting period and the intent, or a set of network performance data names corresponding to the reporting period and the status of the intent.

The state of the intent is the active state, the reporting period is the reporting period corresponding to the active state, and the set of network performance data names corresponding to the state of the intent is the set of network performance data names corresponding to the active state, such as KPIList_S1 and KPIList_S2.

Step 12: The first functional module sends an update performance data subscription message to the output generation and denormalization module.

It can be understood that step 11 and step 12 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 13: The output generation and denormalization module sends an update performance data message to the auxiliary system.

Step 14: The auxiliary system sends performance data to the ENI system.

The performance data includes performance data corresponding to KPI_ValueList_S1 and KPIList_S2 (denoted as KPI_ValueList_S2).

Step 15: The data reading and normalization module sends performance data to the first functional module.

Step 16: The first functional module sends a reply update performance data subscription response (updatePerformanceDataSubscription Response) message to the policy management module, the message includes (fulfillInformation, KPI_ValueList_S1, KPI_ValueList_S2), wherein fulfillInformation is an optional cell, representing an intention whether the goal was met.

In the above example 2, in the process of mutual conversion of the state of the intent from the Active state to the Sleep state, the update of the intent performance data subscription request is implemented, so that the intent only obtains the necessary performance data in the Sleep state, and the reporting period is in the Sleep state. Appropriate reporting cycle.

Example 3 is the second specific process of updating subscription performance data, as shown in FIG. 9 .

Step 1: The intent translation module and the policy management module perform intent conflict processing, and determine that the intent enters a conflict state.

Step 2: The policy management module sends an update performance data subscription (updatePerformanceDataSubscription) message to the first functional module, where the update performance data subscription message includes the reporting period and the status of the intent or a set of network performance data names corresponding to the reporting period and the status of the intent.

The state of the intent is the conflicted state, the set of network performance data names corresponding to the state of the intent is the set of network performance data names corresponding to the conflicted state, namely KPIList_S2, and the reporting period is the reporting period corresponding to the conflicted state.

Step 3: The first functional module sends an update performance data message to the output generation and denormalization module.

It can be understood that step 2 and step 3 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 4: The output generation and denormalization module sends an update performance data message to the auxiliary system.

Step 5: The auxiliary system sends performance data to the ENI system.

The performance data includes performance data corresponding to KPIList_S2 (denoted as KPI_ValueList_S2).

Step 6: The data reading and normalization module sends performance data to the first functional module.

Step 7: The first functional module sends performance data to the policy management module.

Step 8: The intent translation module and the policy management module perform intent conflict processing according to the performance data, and determine that the intent state enters the active state.

Step 9: The policy management module sends an update performance data subscription message to the first functional module. In this case, the update performance data subscription message includes the status of the reporting period and the intent, or a set of network performance data names corresponding to the reporting period and the status of the intent.

Step 10: The first functional module sends an update performance data subscription message to the output generation and denormalization module.

It can be understood that steps 9 and 10 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 11: The output generation and denormalization module sends an update performance data message to the auxiliary system.

Step 12: The auxiliary system sends performance data to the ENI system.

Step 13: The data reading and normalization module sends performance data to the first functional module.

Step 14: The first functional module sends a reply update performance data subscription response (updatePerformanceDataSubscription Response) message to the policy management module, the message includes (fulfillInformation, KPI_ValueList_S1, KPI_ValueList_S2), wherein fulfillInformation is an optional cell, representing intent whether the goal was met.

In Example 3, in the process of the mutual conversion of the state of the intent from the active state to the conflicted state, the update of the intent performance data subscription request is implemented, so that the intent only obtains the necessary performance data in the conflicted state, and the reporting period is the conflicted state the appropriate reporting period.

Example 4 is the second specific process of updating subscription performance data, as shown in FIG. 9 .

Step 1: The policy management module and the intent translation module receive the intent deactivation request.

The state of the current intent can be active or conflicted or sleep.

Step 2: The policy management module sends an update performance data subscription (updatePerformanceDataSubscription) message to the first functional module, where the update performance data subscription message includes the state of the intent.

Among them, the state of the intent is the inactive state.

It can be understood that steps 2 and 3 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 5: The policy management module and the intent translation module receive the intent activation request.

Step 6: The policy management module sends an update performance data subscription message to the first functional module. At this time, the update performance data subscription message includes the status of the reporting period and the intent, or a set of network performance data names corresponding to the reporting period and the status of the intent.

Step 7: The first functional module sends an update performance data subscription message to the output generation and denormalization module.

It can be understood that step 6 and step 7 can also be replaced by the policy management module sending an update performance data subscription message to the output generation and denormalization module, that is, the policy management module does not need to pass the first function module to the output generation and denormalization module. Instead of sending update performance data subscription messages, send update performance data subscription messages directly to the output generation and denormalization modules.

Step 8: The output generation and denormalization module sends an update performance data message to the auxiliary system.

Step 9: The auxiliary system sends performance data to the ENI system.

Step 10: The data reading and normalization module sends performance data to the first functional module.

In Example 4, the update of the intent performance data subscription request is implemented through the mutual conversion process of the intent state from the active state or conflicted state or sleep state to the inactive state.
