Abstract
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.

Claim 1
Independent Claim
129 words
A method of interworking Common Channel Signalling System Number 7 (CCS7) call control messages in a virtual CCS7 data node and setting up appropriate resources to initiate incoming calls into a data network, comprising the steps of: predefining a subset of CCS7 Integrated Services Digital Network (ISDN) User Part (ISUP) messages required for controlling setup of a data network call; translating CCS7 call control messages into a set of primitives used by a network access server (NAS) and checking said set of primitives to authorize call origination; predefining a set of primitives to exchange with the NAS; exchanging primitives with the NAS for controlling setup of data network side transport resources; and establishing NAS control of transport links between a public switched telephone network (PSTN) and said data network.
Claim 2
Independent Claim
