A framework for mobility in wireless personal communications

In personal communications, mobility control in the form of terminal mobility, personal mobility and service portability is essential. On the other hand, the concept of intelligent network (IN) has been applied to personal communications to provide enhanced services as well as personal mobility. In this paper, we analyze the extent to which the intelligent network is used in providing mobility through the universal personal telecommunication (UPT) service and extend this capability to incorporate terminal mobility. This study focuses first on the integration of mobile networks with their inherent terminal mobility into the IN for UPT services. Subsequently, we propose a solution for mobility by introducing an IN-based terminal mobility service and chaining it with the personal mobility service provided by UPT. We show the chaining of the two IN-based services through the call model. Throughout, we illustrate the concepts through the service procedures for incoming calls terminated to a UPT subscriber using a mobile terminal.
