Integrated communication system with intelligent network and telecommunications management network

An integrated communication system with an intelligent network and a telecommunications management network comprising:

• a plurality of service switching points arranged dispersedly to execute basic call processing, each of said service switching points having an agent processor and a call state manager for managing a call state changed sequentially in accordance with the situation of execution of the service, said agent processor enabling a network resource, which includes said basic call processing, to be handled in common as a managed object;
• a service control point for executing centralized control of said service switching points, said service control point having a service logic program where a service execution procedure is described, a service logic execution environment for transmitting an instruction, which is generated with execution of said service logic program, to said service switching points and executing said service logic program in response to a request inclusive of an event from said service switching points, and a first manager processor for providing a managed object interface for communication with the agent processors of said service switching points, said managed object interface having the ability to conceal hardware and software differences among said agent processors, while revealing functional differences among said agent processors;
• an operation system for executing centralized management of said service switching points, said operation system having a management logic program where an operation execution procedure is described, a management logic execution environment for transmitting an instruction, which is generated with execution of said management logic program to said service switching points and executing said management logic program in response to a request inclusive of an event from said service switching points, and a second manager processor for providing the same managed object interface as the one provided by said first manager processor for communication with said service switching points.

• wherein said management logic program of said operation system includes a route-change management logic program, and whenever necessary during execution of a service, said service control point requests said operation system to start the route-change management logic program, and after completion of the route change by said operation system, said service control point proceeds with execution of said service, and
• when a request for switching from a two-party talk service to a three-party conference service is transmitted from said service switching point to said service control point and if none of the service switching points concerned with the two-party talk service is equipped with a resource required for the three-party conference service, said service control point requests said operation system to start the route-change management logic program, and then said operation system changes the present route to another route including said service switching point equipped with the resource required for the three-party conference service.
