Realizing service mobility for personal communications applications

This paper describes the issues concerning service mobility support in a distributed system which facilitates the development of distributed personal communications applications using independently-developed autonomous network servers. The authors mean by service mobility, the capability of the system to hide server interface specifics from the clients by a generic service acquisition mechanism, and to ensure the clients continued access to services despite server access failure and terminal, server and/or user mobility. The system´s architecture can be mapped onto emerging and future public intelligent network architectures, such as Bellcore´s Information Networking Architecture (INA) and Telecommunications INformation Networking Architecture (TINA), which is an international effort
