A robust and integrated Network and Element Management System cdma2000 NMS has been developed using state of the art computing technology to manage the third generation cdma2000 broadband wireless network. The architecture is based on open standards such as CORBA, SNMP, and Java, and the implementation has leveraged many commercial off-the-shelf (COTS) products and proven technologies. The cdma2000 NMS provides access to OA&M capabilities of cdma2000 network elements, including base station controller (BSC), base transceiver station (BTS), mobile switching center (MSC), interworking function (IWF) and selection distribution unit (SDU) with a unified, integrated and Web-enabled graphical presentation. It supports network topology, configuration management, fault management, and performance management. A common management information base is developed for cdma2000 network elements where a common SNMP agent framework is used based on the Ruby architecture (an internal Lucent effort to establish common, reusable architecture and software). The architecture adopts the semantics of the most popular TMN standards within the network elements. These concepts are being implemented as a SNMP management information base (MIB), i.e., for state management and alarm reporting. Interfaces to network elements or other operations support systems can also be achieved easily via CORBA.
