Abstract: A "cluster mobile switching center" (cMSC) is arranged to perform the switching and control functions of a conventional mobile switching center (MSC), including, if desired, the additional functions of a conventional visitor location register (VLR). The cMSC is implemented on distributed processors using modular software. Advantageously, a specific instance of middleware, known as Common Object Request Broker Architecture (CORBA), is used as the communications middleware. Functionally, the cMSC is arranged to have two classes of servers: (1) Interworking managers (IMs) that act as gateways and provide interfaces to external network elements, and (2) core servers that perform call processing (registration, location updates, incoming and outgoing call processing) functions and communicate with each other using CORBA. IMs terminate standard protocols with the external elements and use CORBA to communicate with the core servers. Software objects are defined to perform specific tasks, manage particular resources, and interact to provide end-to-end services.

Abstract: A network management system (NMS) and method is arranged for monitoring, controlling and managing a network that includes,a set of interconnected network elements (NEs). A management agent in each NE interacts with the NMS on behalf of the NE. The system and method utilizes (a) a behavior transition model based on NE status or "health" indicators for passive monitoring, (b) a status updating mechanism with adjustable or "tunable" parameters based on operating conditions, (c) a derivation procedure for correlating ripple effects, and (d) an early-warning model for proactive management.
