In a data access transport service call setup from the Public Switched Telephony Network (PSTN) requires efficient utilization of PSTN resources and signalling infrastructure. A system is disclosed for interworking the PSTN Common Channel Signalling System Number 7 (CCS7) and Internet Protocol (IP) based data networks call setup protocols. The system provides efficient control of network-based signalling and control resources in support of PSTN originated IP-based data calls and services interworking between IP-based networks and other telecommunications networks. An architecture is provided allowing a flexible implementation and distribution of the interworking functions, including functional distribution between an CCS7 interworking function, network controller, Network Access Server, and existing telecommunications network interfaces.

SS7 mediation for data network call setup and services interworking

A network service access system and method for intelligent networks uses a network element called a mediation point between network service switching points (SSP) and third party service provider service control points (SCP). The mediation point acts as a gateway to the AIN network for the service provider SCPs. The mediation point at the boundary of the intelligent network has ports for connection to service providers SCPs and a list of SSPs within the intelligent network to which each respective service provider is allowed access.
