Abstract: For efficient Operations, network elements of a Telecom Network (e.g. Cellular Network) are integrated with Operations support Systems (OSS). Typically the OSS comes from the vendor supplying the key Access and Core network nodes of the network as these nodes are well integrated with the proprietary OSS. Invariably the Network also includes Nodes from other vendors too to provide value added services to subscribers. To get a complete view of the Network for effective Fault and Performance management, Operators & Service providers mandate the integration of 3rd Party Nodes with the existing Proprietary OSS. This Paper presents a brief introduction of Operations Support System (OSS) and discusses common approach for Fault Management (FM) integration of the 3rd party nodes with proprietary OSS in the customer environment |
