Intelligent network/2: The architecture-The technical challenges-The opportunities
J. Gilmour, R.D. Gove · IEEE Communications Magazine · 1988
The Intelligent Network/2 (IN/2) architecture concept diverges from the traditional new service introduction approach by distributing call-processing capabilities across multiple network modules, by constructing network services with service-independent capabilities, and by using standard signaling protocols among the network elements. The IN/2 approach provides opportunities to implement new services while reducing the service introduction interval. The IN/1 architecture provides new-service introduction from a centralized point, allowing users throughout a wide geographic area to have access to the service simultaneously. The IN/2 concept extends the IN/1 approach and sharply reduces the new-service introduction interval. IN/2 applies the premise that multiple network services or service features can be constructed from a set of reusable network capabilities, which apply to many services and are therefore independent of a particular service application. An overview of the IN/2 architecture is presented, highlighting the key technical issues.>
