Building a service assurance system in KT

Abstract

For the past several years, new Internet-centric services have rapidly entered the stage and have been supported by complex networks based on the PSTN, ATM, metro and so forth. These require modifications to current business processes in the OSS. Alternatively, they could require new systems. We have faced difficulties in adopting new data or Internet services in time to market because of complex system structures, inter-operations, etc. To address market needs, we have been promoting the NeOSS (new operations support systems) project since 2001. We have just completed its design level, and are currently implementing it. In these processes, we are still facing many problems and difficulties. We focus on "service assurance", and describe what the problems in the KT OSS are, and how we are approaching them from the point of view of the architectures and technologies and of inter-operations with legacy systems. We also provide an economic analysis based on the key indexes of the KT NeOSS project.
