Performance evaluation of IN based mobility management

Concepts for mobility management in Universal Personal Telecommunication and in third generation mobile communication systems heavily rely upon intelligent network (IN) concepts and infrastructure. In fact, mobility management can be viewed as just another IN service. The necessity to have network performance and capacity figures available arises in a variety of situations, ranging from planning telecommunication networks from scratch to introducing new services into existing networks which may or may not already provide IN-based services. It is important to properly consider the IN as an integrated part of a telecommunication network, since the additional load generated by new IN services may lead to a performance degradation that can spread beyond the IN environment and may affect not only new and existing IN services, but also basic services offered by the network. The authors describe a modelling approach, service logic description linearization, planning tools, analytical approach, the obtainable results, mobility management scenarios, ISDN, architectures and delay analysis.
