System and method for implementing an end office switch with enhanced functionality using an operating system independent distributed self-contained dynamic logic system

摘要

An operating system independent distributed self-contained dynamic logic system is disclosed. The dynamic logic system enables EO functionality in small edge routers or programmable switches which serve a small population of users instead of the rather large population typically served by a 5ESS or DSM100 central office switch. A disclosed method provides the capability for EO switch enhanced functionality that is programmable from a remote location The dynamic logic system may be implemented across several elements, including a subscriber database called a Service Control Point (SCP), a computer called a Service Management Point (SMP) for controlling and distributing programmable logic to implement EO features, and an Edge Switching Point (ESP) for interacting with a physical device (telephone/data endpoint). The dynamic logic system may be introduced at the “intercept” layer between the physical edge switching point device, typically a telephone interface, and a routing network. The routing network may be a packet switched network, a traditional Class-4 network. or an equivalent. This intercept receives inputs from both the device, and the routing network. The processing of these events, to create an application, is controlled by distributed logic. The distributed logic is managed by the SMP. The logic is activated by an operator, and is distributed for consumption. The logic is completely self-contained, requiring only subscriber data to execute, which is obtained on a call-by-call basis. In addition to having all the capabilities of traditional EO switching functions, like playing tones, gathering digits, and routing calls, other functionality may be easily added to enhance and add new dimensions to EO switching.
