Multi service platform architecture for telephone networks
First Claim
1. An intelligent peripheral (IP) system for an intelligent telephony control system within the PSTN (public switched telephone network), said IP system containing multiple processing units for handling telephone calls between directly conversing users of said PSTN, said IP system comprising:
- a first set of call processor units for controlling routing of said telephone calls through a portion of said PSTN occupying a predetermined geographic region served by the respective IP system;
said first set comprising at least one call processor unit, and being expandable modularly to contain additional call processor units;
a second set of service application processor units for controlling various services provided to users of said PSTN having telephones within said predetermined region;
said second set comprising at least one service application processor unit and being expandable modularly to contain additional service application processor units without affecting operational capabilities of any of the call processor units in said first set;
first linking means linking said call processor units in said first set and said service application processor units in said second set, for enabling said processor units linked by said first linking means to communicate with each other and with other elements of said IP system; and
second linking means linking said first linking means to a communication network external to said PSTN, for enabling said call processor units in said first set to route telephone calls through said external communication network and for also enabling said service application processor units in said second set to extend said various services through said external communication network;
said external communication network being configured to transport data unrelated to any voice transmission processes being executed in said PSTN between devices linked to said PSTN in said predetermined geographic region and devices linked to said external network outside of said PSTN.

Abstract
A multiprocessor subsystem, for a portion of the public switched telephone network (PSTN) conforming to architectural standards for advanced intelligent networks (AIN), contains processor elements for participating in management of call routing/switching processes, and other processor elements for participating in management of services provided to PSTN users and subscribers. The processors participating in call routing processes are tightly concentrated to ensure reliable control of respective processes, while the processors participating in management of user services are distributed so as to allow for virtually unlimited growth in new type services without potentially disrupting existing call traffic. This subsystem also contains processor elements having interfaces to networks external to the PSTN; e.g. data networks such as the Internet and World Wide Web, and pager networks. These interfaces allow for users to control enablement and disablement of services to which they subscribe in a manner independent of their telephone line usage (e.g. to enable or disable services such as call waiting, either before or during a call, and/or to define the duration of the respective enablement or disablement as extending to an arbitrary number of calls that the user can define).
