Problems solved by technology
This method can only analyze and identify simple, device-level alarm information correlation, and needs to collect detailed alarm information, which has the disadvantages of complex alarm correlation analysis process and poor versatility
With the continuous expansion of the network scale, when a new network element device is added, the above method cannot perform correlation analysis on the new alarm information generated, especially when technology updates cause large-scale equipment updates in the communication network, domain experts are required Re-adding or modifying the alarm rules is cumbersome and inefficient, far from meeting the actual requirements of telecom operations

Embodiment
[0038] The construction method of the intelligent communication alarm fault location expert system based on meta-knowledge of the present invention, the method and precautions during the specific implementation are as follows:
[0039] 1) Establishment of knowledge base
[0040] (1) It is necessary to establish a communication network device model and a topological connection model between devices according to the topology resource information of the communication network obtained from the resource management system.
[0041] (2) To classify the concepts of the model, a frame-based knowledge storage structure can be adopted.
[0042](3) According to the extracted network topology connection model, the experts formulate the corresponding meta-rules for fault analysis and location, and the description of the rules consists of a rule header and a rule body. The rule header indicates the topology type, and the rule body indicates the analysis method based on the topology type.

The invention provides a method for constructing an intelligent communication alarm fault positioning expert system based on meta-knowledge. In the method, a knowledge base of the expert system is constructed on the basis of the meta-knowledge summarized by medium and high layers of a communication network, alarm information stored and input by a queue with a sliding time window is adopted, a network topological model-based fault positioning reasoning mechanism is designed, the alarm of the time window is reasoned and analyzed, and explanation related to the result reasoning process is given while an analysis result is given. The expert system constructed by the method can quickly position a fault area according to a topological connection relation among equipment from the whole level, and truly simulates the thinking mode of human to reason, so that fault processing efficiency is improved manyfold. The knowledge base is constructed on the basis of the meta-knowledge such as a network topological connection type and the like, so that the expert system has high generality under the condition that the scale of the communication network is increased, can be used for other fields related to topological connection, and has a wide application prospect and high practical value.
Description
technical field [0001] The invention belongs to the field of network monitoring, in particular to an intelligent alarm monitoring technology based on an expert system. Specifically, it is a method of constructing an expert system for communication alarm fault location based on meta-knowledge and its realization technology. Background technique [0002] The mobile communication network has a large scale, complex structure, and a variety of equipment. Various hardware components and software modules generate a large amount of alarm information every day. The massive alarm information makes fault location extremely difficult. At present, the main method is to manually establish an alarm association rule combing table based on the alarm processing experience of domain experts, and perform correlation analysis on alarms according to the association rule combing table, and finally locate the fault. This method can only analyze and identify simple, device-level alarm information c...
