INTRODUCTION

The development of IN architecture was initiated by Bellcore in USA in order to help the

Regional Bell Operating Companies to become more competitive in deregulated

telecommunications environment.

What is an Intelligent Network?An Intelligent Network is a telephone network architecture in which the Service Logic,

handling a call, is located separately from the switching facilities. This allows services to be

added or changed, without having to redesign switching equipment.Historically, intelligence and switching functions were closely integrated in the telephone

exchange. The Intelligent Network introduces the concept of separating these two functions. The

intelligence, or logic, to set up a call or to control a service is separated from the switching.The basic idea of IN has been that it facilitates the provisioning of services independently from

the telecommunications networks and equipment vendors. So, IN acts as a distributing and

centralizing framework of the telecommunications services. With this framework, it is possible

to introduce advanced customer oriented services rapidly and cost effectively.

The objective of IN is to allow the inclusion of additional capabilities to facilitate provisioning ofservice, independent of the service or network implementation in a multi-vendor environment

Characteristics of IN:

Characteristics Description

Quick Development

Time

IN operators can develop and deliver systems and services in the shortest

time possible.

Custom-made

Services

IN service creation tools allow designers to create services which are custom-

made to both Provider and Subscriber specifications.

Flexibility and

adaptability

The underlying hardware and software are configured to grow with newupdates. The IN system as well as the services on the system are easy tomodify.

Cost-effectiveness With a distributing and centralizing framework of the telecom services usingIN, it is possible to introduce advanced customer oriented services rapidly and

cost effectively.

Supportive tobusiness

Services are designed to support business, both in relation to the needs of thesubscriber and of the enduser.

ease of upgrading

smooth migration

Extensive use of information processing techniques; Efficient use of network resources; Modularization and reusability of network functions; Integrated service creations Flexible allocation of network functions to physical entities; Portability of network functions among physical entities;

Standardized communication between network functions Control of some user-specific service attributes; Standardized management of service logic.

IN is applicable to a wide variety of networks, including :

Public switched telephone network (PSTN)

Mobile (GSM,CDMA)

Packet switched public data network (PSPDN)

Integrated services digital network (ISDN)

IN Standardisation

The IN standards are defined by ETSI and CCITT presently ITU-T. IN platform uses ITU-T

standards

IN Conceptual ModelThe IN Conceptual Model (INCM) is defined in the CCITT Recommendation Q.1201. It is a

frame work for the design and description of IN architecture.

COMPONENTS OF IN PLATFORM:


6/20


6

Service Switching Point (SSP)

The Service Switching Point hosts the Service Switching Function.

This belongs to the access network and will communicate with the SCP.

Its main function is to invoke call and non-call related services on the IN platform.

The SSP can be part of a PSTN/ISDN network, but other networks are possible like

PLMN, IP etc.

The hardware used to implement the SSF depends on the access network.

The main difference of SSP from an ordinary switch is in the software where the service

switching of IN is separated from the basic call control.

Service Control Point (SCP)The Service Control Point hosts the Service Control function.

The Service Control Function: Interfaces and interacts with Service Switching Function / Call Control Function,

Specialised resource function (SRF) and service data function (SDF).

Contains the logic and processing capability required to handle IN service attempts.

Is managed, updated and/or otherwise administered by a Service Management Function.


7/20


7

Service Data Point (SDP)The Service Data Point implements the Service Data Function.

It hosts all the data related to the services running on the IN Platform.

The Service Data Function contains customer and network data for real time access by

the SCF in the execution of an IN service.

It interfaces and interacts with SCF as required;

It is managed, updated and/or otherwise administered by an SMF.

The SDF contains data relating directly to the provision or operation of IN services. Thus

it does not necessarily encompass data provided by a third party, such as credit

information, but may provide access to these data.

Service Management Point (SMP) The Service Management Point hosts the Service Management Function.

This entity is involved with activities for service deployment, service provisioning,

control, monitoring and billing.

Specialised Resource Point (SRP)

The SRP provides Special Resource Functions such as customized and concatenated voice

announcements, voice recognition, and Dual Tone Multi-Frequencies (DTMF) digit collection

and contains switching matrix to connect users to these resources. The SRP supports flexibleinformation interactions between a user and the network. The SRP may directly connect to one

or more SSPs, and/or may connect to the signalling network.IN Services Offered by BSNL
