Service level agreement and global QoS index for 3G networks

In addition to discussion of the emergence of service level agreement (SLA) studies for 3G networks, the paper concerns three issues: design of a global SLA index for interconnection regulation on the basis of the "gold-silver-bronze" approach; developing an approach to choose a subset of informative quality indicators; and a compensation and penalty scheme. As a "best practice" the 30-year long Verizon NY experience on QoS regulation is discussed.
