Network has uncertain characteristic as its appearances, which made the reasoning based on probability model become a hotspot in faults diagnosis field. For uncertainty reasoning methods, how to obtain the prior knowledge is very important. In the past, the knowledge usually obtained through artificial experience or random hypothesis, which is very random and not reasonable. In order to obtain prior...
Home NodeB, with the characteristic of self-management, is a newly developed technology to improve the indoor coverage and network capacity for integrated operators. It is expected to substantially reduce the necessary human intervention in network operations, with a significant reduction in operational expenditure (OPEX) and improvement in service quality. In this paper, we analyze Home NodeB's self-management...
In order to improve the customer's QoS satisfaction, a method and a system for fast positioning SLA violations are designed in this paper. First, a kind of database called SLA violation experience database and a system for fast positioning SLA violations are brought forward. Then, a tree called SLA violation experience tree is built based on the Huffman. Finally, the system is tested by some examples...
The paper is to solve how to map OWL information model to database which is very important for sharing information. First, relatively complete and exact mapping rules with the consideration of OWL syntax and semantics is designed. Then, the mapping system from OWL to relational database is implemented based on Jena using Java. Finally, the mapping system is tested by some OWL examples. The mapping...
The interoperability problem of different operational support systems (OSS) is analyzed and the problem is divided into two parts: system-level interoperability and model-level interoperability problems. This paper presents an ontology-based model: shared management information model, which is noted as SMIM, to solve the model-level interoperability problem. Then an improved similarity-based ontology...
