Introduction

This Recommendation contains an introduction to Intelligent Network Capability Set 4 (IN CS-4). It describes the main characteristics and overall capabilities of IN CS-4 and defines the service and network aspects with functional relationships that form the basis for IN CS-4 capabilities. IN CS-4, as successor to IN CS-3, becomes the fourth standardized stage of the Intelligent Network (IN) for the creation and provision of network services. Along with advances in call modelling, security, feature interaction and mobility management, IN CS-4 offers enhanced Number Portability, Mobility, Broadband, Broadband and inter-working with the services in the Internet Protocol (IP) Networks.
