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.
