The Rise and Fall of Intelligence in Networks
What Is An Intelligent Network?
 An intelligent network (IN) is a service-independent telecommunications network wherein intelligence is taken out of the switch and placed in computer nodes that are distributed throughout the network. This provides the network operator with the means to develop and control services more efficiently.
 Intelligent Network systems enable service providers to differentiate themselves from their competitors, increase revenue, and enhance the quality and scope of services to their subscribers.
 Intended both for fixed as well as mobile telecom networks.
 There are two types of INs in the world today.One has been developed by ITU and is called IN CS-1 (Capability Set 1). This is an international IN standard .
 The second one, is the Advanced Intelligent Network, AIN which has been standardized over the past 15 years by Bellcore in the United States.
IN Objectives
 SS7:
– Network that controls functions for setting up and taking down service calls.
– Called Common Channel Signaling System No. 7, or SS7.
– The internal control and network intelligence to an ISDN are provided by SS7.
– SSP:
– “switches” designed to interface with the IN user and SS7 signaling network
– routes service calls to Service Control Points via STP
– SCP:
– database that provides call handling information as response to SSP queries
– stores caller’s service profile
– STP:
– Signaling hub for the transfer of data packets between network nodes
– A network gateway, screening incoming messages based on their contents
– Traffic controller, network manager, and message router.
 SMS:
– Supervision, remote operation/maintenance of SCPs, and software downloading.
 IP:
 Stand-alone computer or integrated with an SSP or SCP
 Installed to perform both voice and data services
 Voice services: announcements, speech recognition, code conversion

SUMMARY
 Intelligent Networks consider the whole telephone network to be one giant machine consisting of smaller parts.
 New opportunities to make business ie. new markets and customers.
 The functionalities are standardized and vendor independent.
 IN has been important for the creation of mobile telephone networks.
 Customized services to users.
 Rapid adaptation to market needs and competition.
