Abstract
This paper analyses the pricing framework of multiservice networks and proposes an improved pricing scheme based on the effective bandwidth concept for taking into account quality of service parameters. Based on the deficiencies noted in the classical effective bandwidth scheme (intolerance to user uncertainty and no guarantee on jitter), we propose an improved charging function which gives more flexibility to the user and we introduce an additional constraint to take into account an eventual guarantee on the jitter or delay variation. We also extended the effective bandwidth pricing scheme to the case with guaranteed jitter, in order to take into account and better deal with the various QoS parameters to be considered in 3G networks. Our proposed charging function improves the classical effective bandwidth scheme, while remaining simple in that it requires that the network only monitors the average rate and duration of each connection. It is also fairer than the classical effective bandwidth scheme as it is more flexible related to user uncertainty and the incentive to an efficient use of network resource is preserved. The constraint on the guaranteed jitter was also tested and proved to be viable.

We define the cell delay variation (CDV) as the (1-α ) quantile of the difference between the delays experienced by any two consecutive packets on the same connection during the entire connection equal, the improvement introduced by hQ′,m is holding time
Summary
A variety of mobile computers equipped with wireless communication devices have become popular. Mobile users want to have diverse services and applications handy These services include file transfer, videoconferencing, electronic mail, graphical user interfaces, remote file systems, etc. The concept of multiservice cellular network is used to denote the integrated infrastructure dedicated to support these applications and services. In the last five years, a whole series of research[3,4,5,6] has been done in the pricing and charging area These works are more or less adapted to the third-generation solutions with various QoS guarantees. This paper analyses the pricing framework of multiservice networks and proposes an improved pricing scheme based on the effective bandwidth concept by taking into account more QoS parameters. By abuse of notation, we suppose that 0 ≤ s0 , t0 ≤ +∞
