Abstract
Today, almost everyone has a personal computing appliance. The rise of personal communications signals the start of a new era in telecommunication. Access to information services via personal communication system also becomes an essential part of future wireless operators’ service offerings. Everyone wants to enjoy not only voice communication but also rich data services at anytime and anywhere while owning mobility.This dissertation focuses on aspects of architecture and services of the next generation personal communications. At first, a scalable Wavelength Division Multiplexing cellular core network is proposed to provide plenty of bandwidth up to Giga-bits/sec, even to Tera-bits/sec. This shuffle-exchange network has self-routing capability, which simplifies multicasting and resource reservation. Meanwhile, the network is core stateless, and hence transition states and signaling traffic can be reduced. The network also supports atomic handoffs, whose transition time is bounded.Then, short message service of multi-receivers for the next generation personal communications is discussed. We demonstrate some approaches to maintain the location information of short message service center consistent to the home location register, and illustrate our scheme for mobile terminated short message transfer. Finally, we simulate and evaluate these multicasting solutions. The result of simulation indicates that the proposed strong consistency approaches have optimal efficiency by adjusting parameters, and the proposed architecture efficiently provides multicast functionality in our cellular backbone network.This work not only provide a further insight on the issues of next generation personal communication system, but also demonstrate a referable methodology to propose and analyze a future personal communication system, which can promote the technology of mobile computing.
