Service Logic Mobility over Intelligent Broadband Networks

The concept of Intelligent Networks (IN) provides a convenient and future safe way for the rapid introduction of broadband multimedia services. The highly sophisticated design of multimedia services and the increasing demand of system resources creates the need for introducing intelligence on the end-systems. In the IN infrastructure this demand is balanced by the intelligence offered by the network itself. However, the task of deployment of new services or even porting of existing services between IN sub-networks is a tedious task that rarely makes use of the network’s intelligence capabilities. The reason is the different implementations of the Service Logic (SL) in IN islands which makes it hard, if not impossible to reuse parts of the software over different IN platforms. This paper proposes ways that enable the remote use of IN capabilities by subscribers which are attached to another IN segment. In this attempt, interconnection issues are resolved using as tools the standard IN modules that is the Broadband Service Control Points (BSCPs) and the Broadband Intelligent Peripherals (B-IPs). Deployment of these modules is based on the use of their service logic execution capabilities and in some cases on an enhancement of their traditional role. To provide the necessary platform and description tools for supporting service logic mobility, service design has been partially based on the concept of movable service logic scripts. Service distribution and service numbering schemes compliant to the network architectures are also provided. Finally, parallel to the description of the proposed models and architectures, practical examples are given.
