The NG-OSS Evolution of Telecom Service Providers: From Network-Focused to Customers-Focused

Now, the telecom service providers are faced with significant challenges as the traditional separated network and service become converged. Customers move to care more about the quality of service, such as the provision time, fault disposal, bill management, and security issues, other than networks. The carriers must integrate their core legacy mainframe operation support systems (OSS) with new generation components that can handle the requirements posed by new service offerings, which means the NG-OSS should pay attention to customers rather than networks. This paper examines the legacy OSS frame with its main component and analysis which part should be weakened or converged, and which part should be enhanced or updated. Then it suggests a more idealized view of a functional OSS architecture that conforms to the concepts of the TeleManagement Forum’s Telecom Operations Map (TOM) model. In the last, it discusses how to evolve the OSS from the networkfocused to customers-focused successfully and smoothly.
