This thesis studies the service provision issues of Universal Personal Telecommunication (UPT) in a single Intelligent Network (IN) and multiple IN environment In particular, the focus is placed on tiie IN-to-IN interaction issues between Public Switched Telephone Networks (PSTNs). These interaction issues include inter-network traffic, storage of service data, IN interface points and call control related issues. Based on these issues, schemes that specify the provision of UPT service can be designed. These schemes are referred to as UPT service provision schemes in this thesis. To illustrate how fl\e interaction issues can be applied to the specification of service provision schemes, a new service provision scheme that specifies the IN-to-IN interactions between PSTNs is designed. This scheme is analysed both qualitatively and quantitatively. Furthermore, a computer simulation is performed to verify flie correctness of the theoretical results. The analysis concludes that the new scheme is suitable for the initial deplojmient of UPT service. This thesis also discusses the IN-to-IN interaction issues that affect UPT service provision between PSTNs and the Public Land Mobile Network (PLMN). A new approach in designing UPT service provision schemes between PSTNs and the PLMN is presented. An example is also provided to illustrate the feasibility of this design technique. In addition, the impact of queuing delay on the different UPT service data distribution schemes is studied. In the study, a new equation that describes the total signalling traffic in a network is derived.
