Telecommunications network architecture enabling local services resale in a legacy network

A telecommunications network for providing intelligent services in a legacy network comprising:

• a delivery unit coupled to a plurality of subscribers, the delivery unit operable to switch calls to and from the plurality of subscribers;
• a service unit coupled to the delivery unit, the service unit operable to perform control, screening, and management of calls through the delivery unit;
• a local switch coupled to the delivery unit, the local switch operable to route calls to and from the delivery unit;
• a service control point coupled to the local switch and the service unit, the service control point including service definitions and logic of services for both legacy and intelligent network services, the service unit operable to determine whether an incoming call is a legacy call or intelligent network call capable of being routed by the local switch or an intelligent network call not supported by the local switch, the service unit operable to forward the supported legacy or intelligent network call to the local switch for processing, the service unit operable to forward the unsupported intelligent network call to the delivery unit for processing;
• a signal transfer point coupling the local switch, the service unit, and the service control point, the signal transfer point operable to process signaling messages to and from the local switch and the service unit;
• a service management system coupled to the service control point;
• a service creation environment coupled to the service management system, the service creation environment operable to define and deploy new telecommunications services;
• an operational support system coupled to the signal transfer point and the service unit, the operational support system operable to provide service support functions.

A method of processing intelligent network calls in a legacy network, comprising:

• receiving an indication that a subscriber desires to make a call;
• providing a dial tone to the subscriber;
• collecting a dialed number from the subscriber;
• determining whether the call is an intelligent network call supported by the legacy network;
• suspending processing of the call in the legacy network in response to the call being an intelligent network call supported by the legacy network;
• sending a query to obtain a translation of the intelligent network call;
• receiving a translation in response to the query;
• providing the translation to the legacy network in order to process the call.
