ABSTRACT:
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.
