In order to build the information model of the new generation of Operation Support System (OSS), we firstly point out that OSS is currently entering the era of big data management, and the Telco Operators are now facing big challenges. We then summarize the difficulties to build the OSS unified information model. After that, the paper surveys the existing information models, and modelling methodologies for OSS, and analyzes their applicability, advantages, as well as disadvantages. Finally, the idea of building the OSS unified information model is put forward. Moreover, the modelling idea has been applied in practice.
