Description

Intent interaction method, device and system

Technical Field

The embodiment of the application relates to the field of communication, in particular to an intentional interaction method, an intentional interaction device and an intentional interaction system.

Background

The telecommunications network management architecture includes an operation and maintenance support system (operation support system, OSS), a management unit and a network element system, as shown in fig. 1. Because the three-layer system does not well define the product boundary, a great deal of technical coupling exists between the systems, and the system integration is complex. For example, the atomic interface of the management and control unit, which is open to the OSS, contains a lot of device technical details, and taking a network encapsulation mode in interface parameters as an example, the network encapsulation mode will adopt different modes along with the development of technology, so that the OSS needs to perceive a lot of device technical details.

To alleviate the above problems, "intentional interactions" have arisen. By intent interactions, in short, it is meant that the service consumer need only pay attention to the goal, or simply provide "intent" representing the demand via "intent expressions", without paying attention to how the result is achieved. However, as telecommunications networks continue to evolve, so will the "intent" that service consumers can propose or that service providers can support. In this case, how to pass the continuously updated "intention" between the service consumer and the service provider is a matter of consideration.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. The terms first, second and the like in the description and claims of the present application and in the above-described figures, and the like, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances and are merely illustrative of the manner in which the embodiments of the application described herein have been described for objects of the same nature. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements, but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

In the description of the present application, "/" means or, unless otherwise indicated, for example, a/B may represent a or B; the term "and/or" in this application is merely an association relation describing an association object, and means that three kinds of relations may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, in the description of the present application, "at least one" means one or more items, and "multiple" means two or more items. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s).

The telecom management forum (telecom management forum, TMF) 2020 proposed the landscape of AN automatic driving network (autonomous network, AN) and defined AN architecture and technical features, indicating that single domain autonomy, intention driving, artificial intelligence Native (AI-Native) is a key for implementing network automatic driving technology in the future. Among these, the core appeal of the intent driver is to achieve decoupling of the network from the business, business and to simplify integration between systems.

As shown in fig. 2, the third generation partnership project (3rd generation partnership project,3GPP) gives an abstract relationship between intent (intent) and policy (rule). By way of example, policies may be derived from rule abstraction, where both rules and policies include specific technical details, and policies include less technical details than rules. Further, intent may be derived from policy abstraction, where intent no longer includes technical details. In the future, further abstractions of intent are also possible.

To facilitate an understanding of the embodiments of the present application, several basic concepts involved in the embodiments of the present application are briefly described.

1. Network management service intention

By definition of TMF, what is meant is a formalized specification (specification) or description of a particular network technology system for expressing a desired object, including requirements, goals, and constraints. The intent of the TMF definition is shown in fig. 3.

Taking the network service release intention as an example, the requirement information may indicate a certain network service, the target information may indicate a bandwidth required for releasing the service, a time delay requirement (for example, time delay <2 ms), and the like, and the constraint information may indicate a source, sink point information, and the like of the network service.

In the embodiment of the present application, the network management service intention refers to the requirement of the network management service consuming entity for the network management service, which may also be referred to as the network management service requirement, and the embodiment of the present application does not limit the name. For example, the network management service intention may be an optical private line service intention.

Under the intentional interaction scene of the application, the network management service providing entity mainly comprises two roles, namely a network management service providing entity and a network management service consuming entity. The network management service providing entity may also be called a network management service provider, or an intention provider (intent provider), or an intention operator (intent handler), etc. The network management service consumption entity may also be referred to as a network management service consumer, or an intention consumer (intenconsumer), or an intention owner (intenducer), etc.

The network management service consuming entity may be a caller of the network management service, may perform operations such as creating, modifying, deleting, querying, etc. of the network management service intention expression, may be configured in a network management system (network management system, NMS), or an element management system (element management system, EMS), or a network device (network equipment, NE), and may be a management function, or a management function entity, or a management entity, or a network device, or a network element, etc., which is not limited in this application.

The network management service providing entity may be a provider of a network management service, perform a corresponding operation according to the received network management service intention expression, and may be configured in the NMS or the EMS or the NE, or may be a management function, or a management function entity, or a management entity, or a network device, or a network element, etc., which is not limited in this application.

The network management service may include at least one of a network planning service, a network construction service, a network maintenance service, and a network optimization service, among others. The network planning service may include a base station deployment or a cell deployment, etc. The network construction services may include services such as network communication device deployment, which may include, for example, fixed access deployment, wireless access deployment, routing device deployment, and so forth. Network maintenance services may include repair troubleshooting of routine network failures, and the like. The network optimization service may include network structure improvement, bandwidth upgrade, network device capacity expansion, etc., for example, the network structure improvement may refer to replacing the ring networking with a combination of ring networking and chain networking. In addition, the network management services may include other services, such as providing targeted network management service packages for certain users, and the like. It should be noted that, the specific content included in the network management service is not limited in this application.

2. Network management service intention template

In this embodiment of the present application, the network management service intention template refers to templated description information of the network management service intention, and may also be referred to as a network management service requirement template, which is not limited by the embodiment of the present application. In particular, the network management service intention template may include an expected (expect) information template and a network object (network target) information template. Optionally, the network management service intention template may further include a context information template. The network management service intent template corresponds to the TMF defined intent, in particular, the network object information template corresponds to a requirement in the TMF defined intent, the desired information template corresponds to a target in the TMF defined intent, and the context information template corresponds to a constraint in the TMF defined intent.

As shown in fig. 4, the description will be given below taking an example in which the network management service intention template includes a desired information template, a network object information template, and a context information template.

The network object information template indicates a templated target network object, wherein the target network object is a physical entity or a logical entity for implementing a network management service. The target network object provides a network management service with network objects that an entity can manage.

For example, the network object may also be referred to as a network management object, wherein the network management object may refer to a network traffic, a network element, a network area, a network service, etc., wherein the network area may be a logical network area, or a physical network area. It will be appreciated that the network object at this point may not be a specific network object, but merely be used to indicate one or more network object types. Furthermore, in one possible design, in the network management service intent template, it may not be specifically indicated what type or types of network objects the network object is, which means that the physical entity or logical entity used to implement the network management service is determined by the network management service consumption entity.

The desired information template indicates a templated target desire, which is used to indicate a target index requirement that the network management service consumption entity can propose or that the network management service providing entity can meet with respect to the performance of the target network object indicated by the network object information template, and may be expressed in terms of a service-level agreement (SLA) of the network management service.

Wherein the desired information template may comprise one or more target index requirements, for example, the desired information template may comprise at least one of a latency parameter, a traffic availability parameter, a bandwidth parameter, as shown in fig. 4. For example, the service availability parameter may be understood as a ratio of a difference between a service duration of the service in a preset time period and an interruption duration of the service in the preset time period to a service duration of the service in the preset time period. It will be appreciated that the target specification requirements included in the desired information template are merely examples, and that the desired information template may also include other target specification requirements.

The context information template is used to indicate constraints of the templated network management service, which may be used to indicate the environment in which the network object information template indicates the target network object is located, or to configure the effective time or period of the network management service intention expression, etc. In the network management service intention template, the context information template may or may not include specific constraint parameters, which means that the specific constraint parameters included in the context information template are determined by the network management service consumption entity.

3. Network management service intention expression

In the embodiment of the application, the network management service intention expression is an instantiation result of a network management service intention template, refers to instantiation description information of the network management service intention, and is generated by a network management service consumption entity based on the network management service intention template and related network management service intention semantic knowledge information.

Illustratively, the network management service intention expression includes a desired information instance, a network object information instance, and a context information instance;

the expected information instance includes an instantiation result of a target index requirement corresponding to the expected information template, and the expected information instance can be determined according to expected information semantic knowledge information, which is described in detail in the following related description of the expected information semantic knowledge information.

For example, the example of the desired information may include a value or a range of values required by the target index corresponding to the desired information template. For example, the target index requirement corresponding to the expected information template includes a bandwidth parameter, and the expected information instance includes a value of 20M for the bandwidth parameter, or a value range of 10M to 15M for the bandwidth parameter. For example, the target index requirement corresponding to the expected information template includes a delay parameter, and the delay parameter example includes a value of 2s for the delay parameter, or a value range of 1s to 5s for the delay parameter.

The target network object indicated by the network object information instance is an instantiation result of the target network object indicated by the network object information template. Illustratively, the target network object indicated by the network object information instance is one of the target network objects indicated by the network object information template, i.e. one of a physical entity or a logical entity for indicating that the network management service is implemented. At this time, the network object information instance indicates a specific certain network object. For example, the network object information template indicates a network service, and the network object information instance indicates an optical private service a, that is, a specific optical private service.

The context information instance is used to indicate constraints of the network management service intent expression. Illustratively, the context information instance includes constraint parameters of the network management service intent expression, for example, the context information instance may include source, sink information, etc. corresponding to a target network object indicated by the network object instance, and for example, the context information instance may include an effective time or period of the network management service intent expression.

4. Network management service intention instance

The network management service intention instance refers to a network management service intention processing procedure that the network management service providing entity creates locally according to the received network management service intention expression (e.g., desired information instance, network object information instance, context information instance).

The network management service intention processing process is used for processing the network management service intention expression. Illustratively, the network management service intent process may include an identification to identify this process; the network management service intent processing process may include computing resources that are used to perform network management service intent translation, query a database (e.g., a semantic knowledge base), and so on; storage resources may be included to host network management service intent expressions, results of network management service intent translations, and the like.

Wherein the network management service intention translation is used to translate the network management service intention expression into a corresponding management operation, which may be an instruction acting on a physical entity or a logical entity, such as adjusting the antenna tilt of a certain base station, opening a power saving switch of a certain cell.

5. Semantic knowledge base

The semantic knowledge base may also be referred to as a semantic dictionary in the telecommunications domain. The semantic knowledge base may be embodied by means of a knowledge graph, which may be implemented, for example, using a resource description framework (resource description framework, RDF).

When the semantic knowledge base is constructed, the semantic knowledge base can be constructed according to the acquired standard information. The standard information herein may include, but is not limited to, 3GPP standard protocol or TMF protocol, etc.

For example, the network management service consumption entity and the network management service providing entity may each configure a semantic knowledge base in advance. In general, the semantic knowledge base configured for the network management service consumption entity is the same as the semantic knowledge base configured for the network management service providing entity to ensure that the semantic understanding of the network management service intent templates by the network management service consumption entity and the network management service providing entity remain consistent.

The semantic knowledge base comprises a plurality of network management service intention templates and network management service intention semantic knowledge information respectively corresponding to the network management service intention templates. Wherein the network management service intention semantic knowledge information is used for describing or explaining the network management service intention template. The network management service intention semantic knowledge information may also be referred to as description information or interpretation information of the network management service intention template. In addition, the network management service intention semantic knowledge information may also be used to parse network management service intention expressions.

For example, the network management service intent semantic knowledge information may include desired information semantic knowledge information, and optionally, the network management service intent semantic knowledge information may also include network object information semantic knowledge information and/or context information semantic knowledge information. The method and the device are not limited to specific forms of the semantic knowledge information of the network object information and the semantic knowledge information of the context information, the semantic knowledge information of the network object information and the semantic knowledge information of the context information can be configured in advance, and the semantic knowledge information of the network object information and the semantic knowledge information of the context information can be updated periodically or when preset conditions are met.

Wherein the expected information semantic knowledge information is used for describing or explaining an expected information template in the network management service intention template. Alternatively, it may be further understood that the network management service consumption entity generates the desired information instance of the network management service intention expression according to the desired information semantic knowledge information and the desired information template. The target specification requirements corresponding to the desired information template may include one or more. Accordingly, the desired information semantic knowledge information may include one or more target metrics requiring semantic knowledge information. Illustratively, each target-index-requirement semantic knowledge information indicates any one or more of the following for that target index requirement:

network management service type, value type, calculation rule, logic rule, service level, indication information for indicating the value required by the configuration target index or indication information for indicating the value range required by the configuration target index.

(1) Network management service type

The network management service type of the target index requirement is used for indicating that the target index requirement is the target index requirement corresponding to the information template in which types of network management service intention templates are required.

For example, bandwidth parameter semantic knowledge information includes: the network management service type corresponding to the bandwidth parameter is optical private line service, and the network management service consumption entity can know according to the semantic knowledge information of the bandwidth parameter: the bandwidth parameter is a target index requirement corresponding to an expected information template in the optical special line service intention template.

In addition, when the network management service intention semantic knowledge information is sent separately from the corresponding network management service intention template, the network management service consumption entity can determine the network management service intention template corresponding to the network management service intention semantic knowledge information according to the network management service type required by the target index, that is, establish the corresponding relationship between the network management service intention semantic knowledge information and the network management service intention template.

(2) Value type

The value type of the target index requirement corresponding to the expected information template is an optional parameter. That is, for a target index requirement for which a specific value needs to be set in a network management service intention expression, the target index requirement semantic knowledge information needs to include the value type of the target index requirement. For a target index requirement that does not require setting a specific value in the network management service intention expression, the target index requirement semantic knowledge information does not need to include a value type of the target index requirement.

Illustratively, the value types may include integer, floating point, boolean, and the like.

For example, bandwidth parameter semantic knowledge information includes: the network management service type of the bandwidth parameter is optical private line service, and the value type of the bandwidth parameter is integer, then the network management service consumption entity can know according to the semantic knowledge information of the bandwidth parameter: the bandwidth parameter is a target index requirement corresponding to an expected information template in the optical special line service intention template, and the value type of the bandwidth parameter is integer. Further, the network management service consumption entity may use the bandwidth parameter as a target index requirement included in the expected information instance in the optical private line service intention expression when generating the optical private line service intention expression, and determine that the value type of the bandwidth parameter is integer.

(3) Calculation rule (cup rule)

Illustratively, the calculation rules may be used to define the calculation or statistical manner of the target index requirements. Wherein the calculation rule is an optional parameter. That is, for a target index requirement that the network management service providing entity needs to calculate (or count), the target index requirement semantic knowledge information needs to include a calculation rule of the target index requirement. There is no need for a network management service providing entity to calculate (or count) a target index requirement, and the target index requirement semantic knowledge information does not need to include a calculation rule of the target index requirement.

Furthermore, the calculation rule may comprise a plurality of optional rules, for example, the delay parameter calculation rule may comprise a delay that is a transmission delay of the entire path, or a delay that is a preset percentage of a transmission delay of the entire path, for example, 50% of a transmission delay of the entire path.

(4) Logic rule (logicalue)

For example, a logic rule may be used for the network management service providing entity to determine whether the desired information instance meets the requirements, wherein the logic rule is also an optional parameter. The logic rules may include a plurality of selectable values.

For example, bandwidth parameter semantic knowledge information includes: the network management service type of the bandwidth parameter is optical private line service, the value type of the bandwidth parameter is integer, and the logic rule of the bandwidth parameter comprises 'greater than or equal to' or 'greater than', and the like. The network management service consumption entity can know according to the bandwidth parameter semantic knowledge information: the bandwidth parameter is the target index requirement corresponding to the expected information template in the optical special line service intention template, the value type of the bandwidth parameter is integer, and the logic rule of the bandwidth parameter is 'greater than or equal to', 'greater than'. That is, in generating the optical private line service intention expression, the network management service consumption entity may select one logic rule according to the above logic rule, for example, select "greater than or equal to", and then the logic rule indicating the bandwidth parameter is "greater than or equal to".

(5) Service level (serviceevel)

By way of example, the service level may refer to a level of service capability possessed by a network management service providing entity. Wherein the service level is also an optional parameter. The service level may include a plurality of selectable values.

For example, the service level of the delay parameter is "seconds", which indicates that the network management service provider can provide a service of the order of "seconds" but cannot provide a service of the order of "subtle".

(6) Indication information for indicating a value of a configuration performance parameter or indication information for indicating a range of values of a configuration performance parameter

Illustratively, the indication information indicating the value of the configuration target indicator requirement indicates that the network management service consumer entity needs to include the value of the target indicator requirement when generating the desired information instance. The indication information for indicating the range of values required for configuring the target indicator indicates that the network management service consumer entity needs to include the range of values required for the target indicator when generating the desired information instance.

For example, if the bandwidth parameter semantic knowledge information includes indication information for indicating the value of the configured bandwidth parameter, the network management service consumption entity needs to include the value of the bandwidth parameter, for example, 5M, when generating the bandwidth parameter instance.

For another example, if the bandwidth parameter semantic knowledge information includes indication information for indicating a value range of the configured bandwidth parameter, the network management service consumption entity needs to include the value range of the bandwidth parameter, for example, 3M to 5M, when generating the bandwidth parameter instance.

6. Architecture for intentional interactions

As shown in fig. 5, the TMF also defines the architecture of the intentional interaction, i.e., the future autopilot network, which can be divided into three layers, including a resource operation layer (Resource Operation), a service operation layer (Service Operations), and a business operation layer (Business Operation). The bottommost layer is a resource operation layer, an I3 interface can be provided for a service operation layer, the service operation layer can provide an I2 interface for a service operation layer, and the service operation layer provides an I1 interface for a user.

Illustratively, the resource operation layer: in engineering practice, the system generally corresponds to a traditional operation and operation maintenance center (operations and maintenance center, OMC) system, provides single-domain network autonomous capability of single-manufacturer network self-configuration, self-optimization and the like, and provides an intentional interface for network resource management for a service operation layer.

Service operation layer: in engineering practice, the layer is a service management center of the network, and the end-to-end service management of the operator system is realized, including service distribution, service maintenance and the like.

Business operation layer: a customer relationship management system (customer relationship management, CRM) may be corresponded in engineering practice, this layer being used to process business orders for operators, as well as customer related information.

As shown in fig. 6 and fig. 7, which are schematic diagrams of specific application scenarios of the embodiments of the present application, it can be understood that the embodiments of the present application may also be applied to other scenarios, which are not limited in this application.

Illustratively, as shown in FIG. 6, the I3 interface may be used to enable interaction between a resource operation layer (as a network management service providing entity) and a service operation layer (as a network management service consuming entity). The I2 interface may be used to enable interaction between a service operation layer (as a network management service providing entity) and a traffic operation layer (as a network management service consuming entity). The service operation layer itself may serve as a network management service consumption entity of the resource operation layer, request intention to the resource operation layer, and may also serve as a network management service providing entity of the business operation layer for opening the intention requested by the business operation layer.

As shown in fig. 7, when the service operation layer is used as a network management service consumption entity, an intention composer (intelt composer) in the service operation layer is used to composes an intention of an upper layer (i.e., a business operation layer) of the service operation layer to form a business level intention expression, i.e., an intention expression of a resource operation layer, and an intention Gateway (intelt Gateway) component can implement negotiation of an intention with the resource operation layer.

When the resource operation layer is used as a network management service providing entity, the resource operation layer can open the capability of a business level intention expression requested by the service operation layer, and an intention catalog (rintntentcatalyst) component of the resource operation layer comprises the intention which can be provided by the resource operation layer, an intention interaction (IntntNegorator) component can realize the negotiation of the intention with the service operation layer, and a capability registration (CapabilityRegister) component can realize the registration and discovery of the self capability.

In some intentional interaction scenarios, two roles are primarily involved, an intended Owner (Intent Owner) and an intended operator (Intent Handler), respectively, as shown in FIG. 8. The intention owner is responsible for the generation of the intention and the management of the life cycle, and the intention operator is an intention executor, so that the intention is converted into lower-layer intention or capability. Illustratively, the intent operator publishes its own capabilities to the intent registry. The intent owner queries the ability to register with the intent registry, initiates an intent interaction based on the ability to register with the intent registry, the intent operator determines possible solutions based on the intent requested by the intent owner, and feeds back the possible solutions to the intent owner for arbitration, from which the intent owner can select one as a result of the intent interaction based on local knowledge.

It can be seen that in the above-described intentional interaction scenario, where the intentional interaction process is initiated by the intended owner, the intended operator feeds back possible solutions to the intended owner, possibly involving specific technical details, thereby requiring the intended owner to have associated technical modeling in order to understand the possible solutions provided by the intended operator. Thus, to understand the possible solutions offered by the intended operator, the intended owner needs to be re-integrated to complete the adaptation each time the intended operator issues an added capability, with the integration period generally being longer.

Currently, as telecommunications networks continue to evolve, the "intent" required by network management service consuming entities or supportable by network management service providing entities will also be updated continuously. In this case, how to achieve the agreed understanding of the semantics of the new network management service intention template by the network management service consuming entity and the network management service providing entity is a problem to be considered.

Based on this, the embodiment of the application provides an intentional interaction method. As shown in fig. 9, the method includes:

step 900: the network management service providing entity obtains a network management service intention template and network management service intention semantic knowledge information, wherein the network management service intention semantic knowledge information is used for analyzing the network management service intention template, the network management service intention template refers to templet description information of the network management service intention, and the network management service intention refers to the requirement of a network management service consuming entity on the network management service.

The network management service intention template may be understood as a new network management service intention template, that is, the network management service providing entity does not provide the network management service corresponding to the network management service intention template to the network management service consuming entity, and the service is a new service that the network management service providing entity can provide. In general, the network management service intention template acquired by the network management service providing entity is a new network management service intention template, which can be understood as including new target index requirements in the expected information template included in the network management service intention template.

For the description of the network management service intention template, reference may be made to the above. The network management service intention semantic knowledge information comprises expected information semantic knowledge information, the expected information semantic knowledge information comprises at least one target index requirement semantic knowledge information corresponding to an expected information template, and the content can be referred to for related description of the target index requirement semantic knowledge information.

Illustratively, an optical private line service intention (optixserviceint) template includes a desired information template, a network object information template, and context information. Wherein the desired information template includes delay parameters. It will be appreciated that the desired information template may also include other target index requirements, such as bandwidth parameters, etc. Assuming that the expected information template further includes bandwidth parameters, if the bandwidth parameters are not new target index requirements (i.e. the network management service providing entity has saved bandwidth parameter semantic knowledge information), and the delay parameters are new target index requirements, the optical private line service intention semantic knowledge information may not carry the bandwidth parameter semantic knowledge information, but only carry the delay parameter semantic knowledge information. Or, the optical private line service intention semantic knowledge information can carry bandwidth parameter semantic knowledge information and delay parameter semantic knowledge information.

In the following, only the semantic knowledge information of the intention of the optical private line service is taken as an example to describe that the semantic knowledge information only carries the semantic knowledge information of the delay parameter.

The optical private line service intention semantic knowledge information comprises time delay parameter semantic knowledge information, wherein the time delay parameter semantic knowledge information comprises service level, calculation rules, logic rules and indication information for indicating the value of the configured time delay parameter.

Wherein the service level includes two selectable items, a "seconds" and a "minutes" level, respectively.

The calculation rule includes two selectable items, namely 'delay is transmission delay of the whole path', and 'delay is preset percentage of transmission delay of the whole path'.

The logic rule includes two selectable options, less than and greater than, respectively.

With reference to fig. 10, the following is a specific data structure example of the above-mentioned optical private line service intention template:

In one possible implementation, when the network management service providing entity obtains the network management service intention template, the network management service providing entity may obtain the network management service capability information, and determine the network management service intention template and the network management service intention semantic knowledge information according to the network management service capability information.

Illustratively, as the telecommunications network evolves itself, when a network management service providing entity discovers a new capability (i.e., network management service capability), the network management service providing entity may register with a capability registry, which determines capability registration information for the network management service capability. When the network management service providing entity acquires the network management service capability information, the network management service providing entity may acquire the network management service capability information from the capability registration information of the network management service capability. Wherein the capability registration information includes network management service capability information. In addition, the capability registration information may include other information in addition to the network management service capability information, which is not limited in this application. For example, the capability registration information may also include constraints on network management service capabilities, callback interface information for network management service capabilities, and the like. Wherein the constraint condition of the network management service capability is used for constraining the resource object with the network management service capability, for example, the constraint condition of the network management service capability can be version number information. For example, part of the resource objects, such as part of the resource objects below the preset version number, may be excluded by the version number information. Callback interface information of the network management service capability is used to indicate a callback interface that invokes the network management service capability, for example, the callback interface information of the network management service capability may include a uniform resource locator (uniform resource locator, URL) of a resource object with the network management service capability.

Illustratively, the network management service capability information includes at least one of a technical field in which the network management service capability is located, a capability type of the network management service capability.

The technical field of the network management service capability is used to describe the field of the network management service capability, for example, the field of the network management service capability may be a radio access network, a radio core network, a bearer network, or the like.

The capability type of the network management service capability is used to describe a specific function corresponding to the network management service capability, for example, the capability type of the network management service capability may be a test capability, an adjustment capability, an emulation capability, or the like.

For example, the network management service providing entity may add a network management service capability (hereinafter referred to as capability a) in the evolution process, register with the capability registry, and obtain capability registration information of the capability a. The capability registration information of the capability A comprises network management service capability information corresponding to the capability A. For example, the capability is in the technical fields of: the capability type of the capability A of the fixed network is the test capability of time delay. As can be seen from the capability registration information of the capability a, the network management service providing entity includes a resource object with the capability a, and the resource object can provide a time delay testing capability for a network object in the fixed network.

Further, the network management service providing entity may determine a network object information template in the network management service intention template according to the technical field of the network management service capability. Illustratively, the network management service providing entity selects a target network object indicated by the network object information template from one or more network objects within the technical field of network management service capabilities.

For example, the initial mapping relationship between the technical field of the network management service capability and the network object information template may be configured in advance, or the mapping relationship between the technical field of the network management service capability and the network object information template is already established in a certain field, and then the mapping relationship between the technical field of the network management service capability and the network object information template in the current field may be obtained by analogy.

The network management service providing entity may determine a desired information template among the network management service intention templates according to the capability type of the network management service capability. Illustratively, the network management service providing entity determines one or more index requirements supported by the network management service capability according to the capability type of the network management service capability, and selects a target index requirement from the one or more index requirements.

For example, the network management service providing entity may determine the target index requirements corresponding to the desired information templates based on the inference knowledge base and the capability type of the network management service capabilities. Wherein the inference knowledge base is used to define which capability support is required for each index requirement. For example, if the capability type of the network management service capability is the capability of testing the time delay and the capability of adjusting the time delay, the network management service providing entity may determine that the desired information template includes the time delay parameter according to the capability type of the inference knowledge base and the capability type of the network management service capability, as shown in fig. 11.

Optionally, the inference knowledge base can be further divided into a radio access network inference knowledge base, a radio core network inference knowledge base and a carrier network inference knowledge base according to different fields. Therefore, the network management service providing entity can firstly determine the inference knowledge base in the related field according to the technical field of the network management service capability, and then determine the target index requirement corresponding to the expected information template according to the inference knowledge base in the related field and the capability type of the network management service capability.

In addition, when the inference knowledge base does not define the index requirements corresponding to some capability types in the current domain, the network management service providing entity may determine the index requirements corresponding to the capability types in the current domain by analogy with reference to the index requirements corresponding to the capability types in other domains.

Further, the network management service providing entity may also determine the semantic knowledge information of the intent of the network management service, i.e. the semantic knowledge information of the desired information, according to the network management service capability information. For example, after the network management service providing entity determines that the desired information template is the delay parameter according to the capability type of the network management service capability, the network management service providing entity may also determine that the service level of the delay parameter is "seconds" or "milliseconds" according to the specific information of the test capability of the delay and the adjustment capability of the delay indicated by the network management service capability information.

In addition, in some embodiments, after the network management service providing entity may register a new capability with the capability registry, the network management service consumption entity may further determine whether the capability has an association relationship with the suspended task, and if the capability has an association relationship with the suspended task, the network management service consumption entity continues to execute the task. A suspended task herein may refer to a task that the network management service consumption entity cannot perform, i.e., the network management service consumption entity does not have the capability to perform the task. For example, the suspended task herein may be a certain network management service intent expression, or a portion of the target specification requirements included by the desired information instance in a certain network management service intent expression. The association between the capability and the suspended task means that after the network management service consumption entity registers the capability, the network management service consumption entity can execute the task through the capability.

Step 910: the network management service providing entity transmits the network management service intention template and the semantic knowledge information of the network management service intention to the network management service consuming entity.

In one example, when the network management service providing entity transmits the network management service intent template and the network management service intent semantic knowledge information to the network management service consuming entity, the network management service providing entity broadcasts the network management service intent template and the network management service intent semantic knowledge information.

For example, the network management service providing entity transmits the network management service intention template and the network management service intention semantic knowledge information to the network management service consuming entity using the websocket protocol.

In an example, when the network management service providing entity sends the network management service intent template and the network management service intent semantic knowledge information to the network management service consuming entity, the network management service providing entity sends a hypertext transfer protocol (hyper texttransfer protocol, HTTP) message to the network management service consuming entity, the HTTP message including the network management service intent template and the network management service intent semantic knowledge information. In addition, the network management service intention template and the network management service intention semantic knowledge information may be separately transmitted, which is not limited in this application.

In another example, the network management service providing entity receives a subscription request message from the network management service consuming entity, where the subscription request message is used to request the network management service providing entity to notify the network management service consuming entity of a new network management service intention template and corresponding network management service intention semantic knowledge information, that is, a network management service intention template and corresponding network management service semantic knowledge information that are newly released by the subscription network management service providing entity, the network management service providing entity may send a subscription notification message to the network management service consuming entity, where the subscription notification message includes the network management service intention template and the network management service intention semantic knowledge information.

In some possible embodiments, the network management service consumption entity may specifically subscribe to a newly published network management service intention template and corresponding network management service semantic knowledge information of at least one domain, that is, subscribe to the newly published network management service intention template and corresponding network management service semantic knowledge information for a certain domain or several domains, where the subscription message may further include domain information, and further, the network management service providing entity may send the network management service intention template and corresponding network management service semantic knowledge information to the network management service consumption entity when determining that the network management service intention template and corresponding network management service semantic knowledge information belong to the domain to which the network management service consumption entity subscribes according to the domain to which the network management service intention template and corresponding network management service semantic knowledge information belong. When it is determined that the network management service intention template and the corresponding network management service semantic knowledge information do not belong to the field of network management service consumption entity subscription, the network management service providing entity may not send the network management service intention template and the corresponding network management service semantic knowledge information to the network management service consumption entity.

Step 920: the network management service consumption entity generates a network management service intention expression according to the network management service intention semantic knowledge information and the network management service intention template.

Illustratively, the network management service consumption entity updates the semantic knowledge base of the network management service consumption entity according to the received network management service intention template and the corresponding network management service intention semantic knowledge information. Accordingly, when the network management service providing entity provides the newly added network management service intention template, the network management service consuming entity needs to update the network management service intention template and corresponding semantic knowledge information of the network management service intention to the semantic knowledge base of the network management service providing entity.

Further, the requirement information of the network management service consumption entity for the network management service may include identification information of a network object for implementing the network management service, requirement information about target index requirements, and context information of the network management service. For example, if the network management service consumption entity desires that the network management service providing entity implement the optical private line service a for less than 5s, the network management service consumption entity's requirement information for the network management service may include identification information of the optical private line service a, the requirement information about the target index requirement indicates that the delay is less than 5s, and the context information of the network management service includes IP addresses of two end nodes of the optical private line service a, and the like.

Further, when the network management service consumption entity generates the network management service intention expression according to the network management service intention semantic knowledge information and the network management service intention template, the network management service consumption entity generates a desired information instance according to the desired information template, the desired information semantic knowledge information and the requirement information about the target index requirement. The network management service consumption entity generates a network object information instance according to the network object information template and the identification information of the network object for realizing the network management service, and the network management service consumption entity determines the context information instance according to the context information of the network management service.

The specific process of generating the optical private line service intention expression by the network management service consumption entity is described below by taking the example that the network management service consumption entity hopes the network management service providing entity to realize that the optical private line service A requires less than 5 s.

Specifically, the network management service consumption entity determines that the optical private line service intention template includes a network object information template according to the segment 1, and the network management service consumption entity fills the network object information template into the identification information of the optical private line service a, that is, determines that the network object information instance in the optical private line service intention expression includes the identification information of the optical private line service a, as described in detail in the following segment a.

The network management service consumption entity also determines that the optical private line service intention template comprises a desired information template according to the segment 3, and determines that the desired information template comprises a time delay parameter according to the segment 4, and the network management server generates a desired information instance, as described in detail in the following segment B.

The network management service consumption entity also analyzes the optical private line service intention semantic knowledge information (i.e. delay parameter semantic knowledge information), determines that the delay parameter semantic knowledge information includes a service level (serviceevel) according to the segment 5, determines that the selectable items included in the service level are "seconds" (and "minutes" (according to the segment 6 and the segment 7), and can determine that the service level (serviceevel) of the delay parameter in the optical private line service intention expression desired information instance is "seconds" (according to the segment C described below because the optical private line service a requires a delay less than 5 s.

The network management service consumption entity further determines that the semantic knowledge information of the delay parameter includes a calculation rule (camurates rule) according to the segment 8, and determines that the calculation rule (camurates rule) includes options of "transmission delay (Sum) with delay being the whole path" and "preset percentage (Sum) of transmission delay being the whole path" according to the segment 9 and the segment 10, and since the optical dedicated line service a is a service between two nodes, the optical dedicated line service a requires a delay less than 5s, the calculation rule (camurates rule) of the delay parameter in the expected information instance in the optical dedicated line service intention expression can be determined as "transmission delay (Sum) with delay being the whole path", as detailed in the segment D below.

The network management service consumption entity also determines that the latency parameter semantic knowledge information includes logic rules (LogicalRule) according to the segment 11, and determines that the logic rules include options of "less than (Lessthan)" and "greater than (Greaterthan)" according to the segment 12 and the segment 13, and determines that the logic rules (LogicalRule) of the latency parameter in the optical line service intention expression is "less than (Lessthan)" because the optical line service a requires less than 5s, as described in detail in the segment E below.

The network management service consumption entity also determines that the semantic knowledge information of the delay parameter includes indication information for configuring the value of the delay parameter according to the segment 14, and determines that the value of the delay parameter in the special line service intention expression is '5' because the special line service a requires less than 5s, as described in detail in the segment F below.

In addition, the network management service consumption entity may further determine that the optical private line service intention template includes a context information template according to the segment 2, and the network management service consumption entity fills the context information template into IP addresses of two end nodes of the optical private line service a, that is, determines a context information instance, which is described in detail in the following segment G.

Illustratively, the specific data structure of the network management service intention expression is as follows:

(the above fragment is denoted as fragment A, and the network management service consumption entity determines that the network object information instance in the optical private line service intention expression is optical private line service A)

(the above-mentioned segment is denoted as segment B), and the network management service consumption entity determines that the optical private line service intention expression includes a desired information instance, and the desired information instance includes a delay parameter

{

“servicelevel”:”Secondlevel”

(the above segment is denoted as segment C, "servicevel" means "second level" indicating that the network management service consuming entity determines that the service level of the delay parameter in the desired information instance in the optical private service intention expression is "second level")

“CaculateRule”:”sum”

(the above segment is denoted as segment D, "Cacute rule" sum ", indicating that the calculation rule of the network management service consumption entity to determine the delay parameter in the expected information instance in the optical private line service intention expression is" delay is the transmission delay of the whole path ")

“LogicalRule:”Lessthan”

(the above fragment is denoted as fragment E, "LogicalRule:" Lessthan ", indicating that the logic rule of the network management service consuming entity to determine the delay parameter in the expected information instance in the optical private service intention expression is" less than ")

“value”:”5”

(the above fragment is denoted as fragment F, and the network management service consumption entity determines that the value of the delay parameter in the expected information instance in the optical private service intention expression is "5")

(the above fragment is denoted as fragment G, and the network management service consumption entity determines that the context information instance in the optical private line service intention expression includes IP addresses of two end nodes).

Step 930: the network management service consumption entity sends the network management service intention expression to the network management service providing entity.

Step 940: the network management service providing entity determines that the analysis of the network management service intention expression is successful according to the semantic knowledge information of the network management service intention, and executes the network management service intention expression.

It will be appreciated that the network management service providing entity may parse each parameter in the network management service intention expression based on the network management service intention expression and the semantic knowledge base (the semantic knowledge base includes network management service intention semantic knowledge information), and execute the network management service intention expression after the parsing is successful, that is, a network management service intention processing procedure (i.e., a network management service intention instance) created locally.

Illustratively, the network management service providing entity may further determine that the network management service intention expression is successfully parsed according to the network management service intention template and the network management service intention semantic knowledge information.

Illustratively, the specific procedure of the network management service providing entity to parse the received optical private line service intention expression in step 920 is described below by taking the optical private line service intention expression as an example:

wherein the network management service providing entity determines that the optical private line service intention template comprises a network object information template according to the segment 1, determines that the optical private line service intention expression comprises a network object information instance according to the segment A, and the network object information instance comprises identification information of the optical private line service A.

The network management service providing entity also determines from segment 3 that the optical private line service intention template includes a desired information template and from segment 4 that the desired information template includes a delay parameter. The network management service providing entity also determines from segment B that the optical private service intention expression includes a desired information instance.

The network management service providing entity determines the latency parameter semantic knowledge information to include a service level (serviceevel) according to the segment 5, determines the selectable items included in the service level to be "seconds" (and "minutes" (according to the segments 6 and 7), and determines the service level (serviceevel) of the latency parameter in the desired information instance in the optical private service intention expression to be "seconds" (according to the segment C).

The network management service providing entity determines that the delay parameter semantic knowledge information includes a calculation rule (camurarule) according to the segment 8, determines that the selectable items included in the calculation rule (camurarule) are "transmission delay (Sum) of the delay as a whole path" and "preset percentage (Sum) of the delay as the transmission delay of the whole path" according to the segment 9 and the segment 10, and determines that the calculation rule (camurarule) of the delay parameter in the desired information instance in the optical private line service intention expression is "transmission delay (Sum) of the delay as a whole path" according to the segment D.

The network management service providing entity also determines that the latency parameter semantic knowledge information includes a logic rule (logic rule) according to the segment 11, determines that the logic rule includes selectable items of "less than (lessman)" and "greater than (Greaterthan)" according to the segments 12 and 13, and determines that the logic rule (logic rule) of the latency parameter in the optical private service intention expression is "less than (lessthian)" according to the segment E.

The network management service providing entity also determines that the semantic knowledge information of the delay parameter includes indication information for configuring the value of the delay parameter according to the segment 14, and determines that the value of the delay parameter in the optical private line service intention expression is "5" according to the segment F.

Further, the network management service providing entity determines that the optical private line service intention template includes a context information template according to the segment 2, and determines that the context information instance includes IP addresses of two end nodes according to the segment G.

So far, the network management service providing entity determines that the optical private line service intention expression accords with the optical private line service intention template, and the network management service intention expression is successfully analyzed.

The network management service providing entity can determine the path between the two nodes according to the testing capability and the adjusting capability of the time delay of the network management service providing entity, and the time delay of the optical private line service A is ensured to be less than 5s. It can be understood that the present application is not limited to a specific implementation manner in which the network management service providing entity guarantees that the optical private line service a has a delay of less than 5s.

By adopting the method, the network management service providing entity sends the newly-added network management service intention template and related network management service intention semantic knowledge information to the network management service consumption entity, so that the consistency of semantic understanding of the network management service providing entity and the network management service consumption entity on the newly-added network management service intention template can be realized, the purpose of accelerating the intention interaction agreement can be realized, the negotiation cost of the intention interaction party can be reduced, the technical details can be related less, the technical coupling can be reduced, and the system integration cost can be reduced.

In order to achieve the consistent understanding of semantics of the new network management service intention template by the network management service consumption entity and the network management service providing entity, the embodiment of the application provides an intention interaction method. As shown in fig. 12, the method includes:

step 1200: the network management service consumption entity acquires a network management service intention template and network management service intention semantic knowledge information.

The network management service intention semantic knowledge information is used for analyzing a network management service intention template, the network management service intention template refers to templet description information of the network management service intention, and the network management service intention refers to the requirement of a network management service consumption entity on the network management service.

The network management service intention template is a new network management service intention template, namely, the network management service providing entity does not provide the network management service corresponding to the network management service intention template for the network management service consuming entity, and a new service request is provided for the network management service consuming entity. In general, the network management service intention template acquired by the network management service providing entity is a new network management service intention template, which can be understood to include new target index requirements.

It should be noted that, the specific manner of the network management service consumption entity obtaining the network management service intention template and the corresponding semantic knowledge information of the network management service intention is not limited in the application, for example, the network management service consumption entity may obtain the above content through a third party device.

Step 1210: the network management service consumption entity sends a network management service intention template and semantic knowledge information of the network management service intention to the network management service providing entity.

Step 1220: the network management service providing entity updates a semantic knowledge base of the network management service providing entity according to the received network management service intention template and the network management service intention semantic knowledge information, wherein the semantic knowledge base is used for storing the network management service intention template and the network management service intention semantic knowledge information.

Illustratively, when the network management service consuming entity provides the newly added network management service intention template, the network management service providing entity needs to update the network management service intention template and corresponding semantic knowledge information of the network management service intention to the semantic knowledge base of the network management service providing entity. Illustratively, the network management service providing entity updates a semantic knowledge base of the network management service providing entity according to the semantic knowledge information of the network management service intention, and analyzes the network management service intention expression according to the updated semantic knowledge base, and further, the network management service providing entity determines that the analysis of the network management service intention expression is successful.

Further, the network management service consumption entity generates a network management service intention expression according to the network management service intention template and the semantic knowledge information of the network management service intention, which is described in detail in step 920. The network management service consumption entity sends the network management service intention expression to the network management service providing entity. The network management service providing entity determines that the analysis of the network management service intention expression is successful according to the semantic knowledge information of the network management service intention, and executes the network management service intention expression.

In addition, in the case of determining that the analysis of the network management service intention expression is successful, the network management service providing entity also needs to determine whether the capability of executing the network management service intention expression is provided.

Illustratively, the network management service providing entity may determine whether it is capable of executing the network management service intention expression based on the inference knowledge base and the network management service capability information (may also be capability registration information). For example, the expected information instance in the network management service intention expression indicates that the time delay is less than 2s, the network management service providing entity can determine that the capability required by the target index for the time delay is the testing capability of the time delay and the adjusting capability of the time delay according to the reasoning knowledge base, and further according to whether the network management service capability information has the testing capability of the time delay and the adjusting capability of the time delay, if so, the network management service intention expression can be executed, the network management service intention instance is generated, and otherwise, the network management service intention expression cannot be executed. In addition, it can also combine the network management service ability information to further judge whether the service level with support "second level" is supported, if so, the network management service intention expression can be executed, and the network management service intention instance is generated, otherwise, the network management service intention expression cannot be executed.

By adopting the method, the consistency of the newly added semantic understanding of the network management service providing entity and the network management service consuming entity can be realized, the achievement of the agreement of the intentional interaction can be quickened, the negotiation cost of the intentional interaction entity and the network management service consuming entity is reduced, the technical details are less involved, the technical coupling is reduced, and the system integration cost is reduced.

Based on the content of fig. 6 and 12 described above, the network management service consumption entity may also modify the network management service intent expression.

In some possible embodiments, the network management service consumption entity may further send a first intent modification request message to the network management service providing entity, the first intent modification request message being used to modify the value or the range of values required by the target indicator in the network management service intent expression. For example, the first intent modification request message is used to modify the value of the latency parameter, e.g., from less than 3s to less than 2s, or the first intent modification message is used to modify the value of the bandwidth parameter, e.g., from 2M to 3M.

For example, the network management service providing entity determines according to the self-capability or the resource occupation condition, and if the modified target index requirement value or the modified target index requirement value range can be met, the network management service providing entity sends a first intention modification response message to the network management service consuming entity, wherein the first intention modification response message indicates that the modification is successful. If the modified target index requirement value or value range cannot be met, the network management service providing entity sends a first intention modification response message to the network management service consumption entity, wherein the first intention modification response message indicates modification failure. When the first intention modification response message indicates a modification failure, the intention modification response message carries a reason for the modification failure, for example, the reason for the modification failure is that the network management service providing entity does not have enough resources, etc.

In some possible embodiments, the network management service consumption entity may further send a second intent modification request message to the network management service providing entity, the second intent modification request message indicating a target index requirement newly added in the desired information instance in the network management service intent expression.

Further, the network management service providing entity sends a second intention modification response message to the network management service consuming entity, wherein the second intention modification response message indicates that the analysis of the new target index requirement is successful and has the capability of supporting the new target index requirement, or the analysis of the new target index requirement is successful but does not have the capability of supporting the new target index requirement, or the analysis of the new target index requirement fails.

In an example, the network management service providing entity may determine whether the new target index requirement can be successfully resolved according to the semantic knowledge base, and determine which capability support is required for the target index requirement through the inference knowledge base when the new target index requirement is successfully resolved. Further, the network management service providing entity sends a query message to the capability registry, the query message indicating the capability required to support the target index requirement, and the capability registry determines whether the network management service providing entity has the capability required to support the target index requirement according to the query message, and sends a response message to the network management service providing entity.

If the response message indicates that the network management service providing entity has the capability of supporting the newly added target index requirement. The network management service providing entity sends a second intention modification response message to the network management service consuming entity, wherein the second intention modification response message indicates that the newly added target index requirement is successfully analyzed and has the capability of supporting the newly added target index requirement. Further, the network management service providing entity provides the service corresponding to the newly added target index requirement for the network management service consuming entity, namely, generates a network management service intention instance. In addition, the network management service providing entity can also determine whether to provide the service corresponding to the newly increased target index requirement for the network management service consuming entity according to the change of the self resource occupation condition. For example, if the current resource occupancy cannot guarantee the newly added target indicator requirement, the second intent modification response message may further include indication information, where the task for the newly added target indicator requirement of the network management service consumption entity is suspended or temporarily unable to be executed, and at this time, the indication information may further include a cause value, for example, the cause value does not have enough resources for the network management service providing entity.

If the response message indicates that the network management service providing entity does not have the capability of supporting the newly added target index requirement. The network management service providing entity sends a second intention modification response message to the network management service consuming entity, the second intention modification response message indicating that the newly added target index requirement is successfully resolved but does not have the capability of supporting the newly added target index requirement. Further, the network management service providing entity can monitor the capability change of the network management service providing entity, and when the network management service providing entity has the capability of supporting the newly increased target index requirement, the network management service consuming entity is provided with the service corresponding to the newly increased target index requirement. For example, the network management service providing entity may first suspend the task required by the target index newly added by the network management service consuming entity and monitor its own capability change.

For example, in the network management service intention expression for the service B, the value of the bandwidth parameter is 5M, the network object information instance is the service B, and the context information instance includes source and destination information corresponding to the service B. The network management service consumption entity sends a second intention modification request message to the network management service providing entity, wherein the second intention modification request message is used for indicating a newly increased target index requirement in a desired information instance in a network management service intention expression aiming at the service B, for example, the newly increased target index requirement is a time delay parameter, and the value of the time delay parameter is 3s. The network management service providing entity analyzes the time delay parameter and the value of the time delay parameter according to the semantic knowledge base, determines that the time delay of the second intention modification request message request service B is less than or equal to 3s, and further determines which capabilities are required to support the time delay through the inference knowledge base. For example, the capabilities required by the inference knowledge base to define the delay parameters are the testing capabilities of the delay and the adjustment capabilities of the delay. The network management service providing entity sends a query message to the capability registry, the query message indicating the testing capability of the time delay and the adjusting capability of the time delay, and the capability registry determines whether the network management service providing entity has the testing capability of the time delay and the adjusting capability of the time delay according to the query message and sends a response message to the network management service providing entity.

If the response message indicates that the network management service providing entity has the testing capability and the delay adjusting capability of the delay. The network management service providing entity sends a second intention modification response message to the network management service consuming entity, wherein the second intention modification response message indicates that the analysis of the time delay parameter is successful and has the capability of supporting the time delay parameter. Further, the network management service providing entity can ensure that the time delay of the service B is less than or equal to 3s by adjusting the transmission path of the service B and the like.

If the response message indicates that the network management service providing entity does not have the testing capability and the delay adjusting capability of the delay. The network management service providing entity sends a second intent modification response message to the network management service consuming entity, the second intent modification response message indicating that the delay parameter resolution was successful but not having the capability to support the delay parameter. Further, the network management service providing entity can suspend the time delay task of the service B and monitor the capacity change of the service B, and when the network management service providing entity has the testing capacity and the adjusting capacity of the time delay, the time delay of the service B is ensured to be less than or equal to 3s.

In another example, the network management service providing entity may determine whether the latency parameter can be successfully resolved according to the semantic knowledge base, and when the latency parameter resolution fails, the network management service providing entity sends a second intent modification response message to the network management service consuming entity, the second intent modification response message indicating that the latency parameter resolution fails. Meanwhile, the network management service providing entity may request the latency parameter semantic knowledge information from the network management service consuming entity.
