In this paper, we propose an ATM-based Personal Communication Service (PCS)
network architecture with ring-based access networks. We also propose a si
mple ring management scheme using ATM Add-Drop-Multiplexers (ADM). The ring
has a Virtual Star topology, and we manage its bandwidth at two levels: Vi
rtual Path (VP) level and Virtual Channel (VC) level. We consider four diff
erent types of configurations according to the locations of visitor locatio
n register (VLR) and mobile switching center (MSC) functions, and obtain si
gnaling load and processing load. A 150 Mb/s-dual ring can support about 5,
500 homogeneous ON-OFF voice sources. This ring capacity corresponds to cov
ering approximately 180 cells in the case of 30 connections per cell. Even
though we are here concerned with evaluating the proposed network for voice
traffic, we can extend this study to the analysis of the proposed ATM-base
d PCS network accommodating various types of multimedia traffic as a furthe
r study.
