Abstract: A communications services network platform has a multi-layered software architecture residing on a host computer. The network platform connects to a communications network and includes a call processing stack, a link layer, and a service support subsystem. The call processing stack implements call processing by processing events associated with a communication path through the communications network and has an application layer, representing each active call being processed by the call processing stack, and a resource layer, including software abstractions of physical resources located outside the host computer. The link layer manages a communications link between physically connected physical resources and the call processing stack. The service support subsystem executes services requested by the call processing stack. The platform manages and controls communications events associated with the communication path to complete a request for services between nodes on the communication network.

Abstract: A flexible network platform and call processing system are disclosed. The call processing system includes a particular call processing architecture and a resource managing system which allow new services to be implemented rapidly. An OAM&P subsystem and systems for performing data provisioning and service creation are each provided for use with the disclosed call processing system. The call processing system may include a call processing mechanism for performing call processing in accordance with defined service logic, and call processing resources connected to the call processing mechanism. The call processing resources are designed so that any service logic unit may be linked to any particular event that might occur in connection with the call processing system. A resource managing system is also disclosed for assigning resources for use by a call processing system. A resource is assigned in response to a request made by the call processing system specified capability.
