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 mapping method is given to realize the one-more concept mapping. The similarity-based ontology mapping method divides the mapping process into five steps: ontology acquisition, ontology formalization, concept similarity estimation, ontology mapping, and result presentation. At last, a SMIM-based prototype system is introduced to show how system works with the help of SMIM mapping.
