Intelligent Networks The Intelligent Network (IN) standards are divided into the Telcordia standardisation called Advanced Intelligent Networks (AIN) and the International Telecommunications Union telecommunications (ITU-T) IN standards capability sets. The Telcordia standards are used mainly in North America, whilst the ITU-T standards are relevant in pretty much the rest of the world. | Next Generation Network Services Neill Wilkinson Copyright 2002 John Wiley Sons Ltd ISBNs 0-471-48667-1 Hardback 0-470-84603-8 Electronic 3 Intelligent Networks INTRODUCTION The Intelligent Network IN standards are divided into the Telcordia standardisation called Advanced Intelligent Networks AIN and the International Telecommunications Union telecommunications ITU-T IN standards capability sets. The Telcordia standards are used mainly in North America whilst the ITU-T standards are relevant in pretty much the rest of the world. Other work has taken place notably by a group known as TINA-C the Telecommunications Information Networking Architecture Consortium looking at the longer term architectures for distributed intelligence in telecommunications networks. The early implementations of IN were based on a database performing number translation of non-geographic numbers such as the US 800 services and these basic services continue today. These services were built on a network enabled by signalling system number 7 SS 7 and IN continues to build on SS 7. More recently IN implementations cover a more extensive set of services from time of day routing plans find-me follow-me services pre-paid mobile services wireless intelligent networks calling card services to advanced network-based call centre agent skill routing. The basic aim of IN is to decouple the service logic from the control of the switch fabric a stage further than could be achieved by the use of a stored program controller and to create a platform that allows new services to be constructed from smaller building blocks. This later capability is expressed in as integrated service creation and implementation by means of the modularised reusable network functions . The principle business aim of IN is the removal of a dependency on switch manufacturers for the provision of new services. In order to achieve this 34 INTELLIGENT NETWORKS aim the use of an SS 7 infrastructure is a prerequisite. Section .
