Problems solved by technology

However, there is no practical tool yet
The main problem is that the action language used to describe the action semantics of the model is not complete and is too complicated
[0003] Since the Unified Modeling Language is an abstract language that does not contain domain-specific semantics, the model established according to the Unified Modeling Language can only guarantee to follow the specifications of the Unified Modeling Language, but cannot guarantee to follow the domain semantics and domain constraints

Embodiment 1

[0074] Embodiment 1 Model-based network management mode

[0075] First, domain experts and modelers abstract domain knowledge and establish domain metamodels through domain tools. Including the establishment of domain concepts and domain relationships and domain constraints, as well as icons presented by model elements, views of the internal structure of complex model elements, and so on. Figure 4 A specific network meta-model is given.

[0076] Figure 4 The given metamodel shows that the router (Router) can contain ports, and the router is connected to the host (Host) and the network through the port. These network domain knowledge will constrain the modeling process. modeled as Figure 5 shown.

[0077] When modeling, links can be established between routers and hosts and between routers and networks. When you want to establish links between hosts and networks, the constraint validator of the domain model tool will perform verification to ensure that this does not con...

Embodiment 2

[0080] Embodiment 2 Requirements analysis and design based on modeling tools in this field

[0081] This domain modeling tool can also be used as a UML-based CASE tool in the requirements analysis and design stages of the software development process. Since the domain language can be established through meta-modeling, this tool can be applied to any field and is not limited to telecommunications field. After the domain language is established, the next work is the same as that of a general UML modeling tool. System static information modeling based on UML class diagram can be carried out.

Abstract

The present invention relates to a telecommunication-field modeling tool and a modeling method based on unifying a modeling language, which belong to the field of system software and application software of a computer. A four-layer metadata structure based on unifying a modeling language constructs mechanisms of element modeling and two-stage modeling; the element modeling establishes a domain element model of the telecommunication field, and the modeling establishes a specific applied model in the telecommunication field; a concrete member contacts concrete equipment in the model by a customization function. The equipment is displayed, controlled and managed by the models. The element model comprises domain knowledge and constrains modeling behavior; a model established in a modeling process is ensured to conform to the constraint of the field. Because the equipment is displayed and managed by the customization mode, the abstraction levels of solving problems are improved. Therefore, developers can pay attention to the logic of the problems rather than the details of low-level realization. The efficiency and the correct rate of software development are improved, and developing cycles are shortened. A modeling method of telecommunication field based on unified modeling language includes structuring two-stage of modeling mechanism for elementary modeling and modeling based on structure of unified modeling language of four layer elementary data, using elementary modeling to establish field elementary model and modeling to establish a concrete application model, applying custom - made function to relate a concrete component in model to a concrete equipment and using model to control and supervise equipment.

Description

technical field [0001] The invention belongs to the field of computer system software and application software, and in particular relates to a field modeling tool and a model-based method for presenting and managing network equipment, network performance, and network faults. Background technique [0002] Currently, the popular object-oriented modeling tools include Rational Rose developed by Rational Corporation. There are Beida Jade Bird object-oriented modeling tools in China. These modeling tools are based on a common modeling language - Unified Modeling Language. The Unified Modeling Language is an object-oriented modeling language standard initiated by the Object Management Organization, and it has become the de facto standard of object-oriented modeling. The unified modeling language describes the static structure information of the system through classes, objects, relationships, etc., and describes the dynamic behavior of the system through sequence diagrams and sta...
