Abstract

The heterogeneous mixture of 4G wireless networks brings together many different interconnecting wireless IP domains, each following different QoS models thus complicating the overall end-to-end QoS process. The target of end-to-end QoS provisioning in wireless Internet has become even more challenging because of the combination of different types of end-user traffic requiring different QoS performance characteristics. Further, we can witness these days that mobile terminals are having the capability to access many of these wireless network types at the same time. The networks are very different in terms of delay, jitter and data rate. As terminals move between different access networks it becomes an important issue how to map resource reservations between different networks in order to maintain QoS behavior. In this paper, we present a novel mechanism for achieving service continuity through a Translation Matrix, which maps QoS parameters between different access networks. Each network maintains matrices corresponding to the traffic behavior of the different available traffic classes. The matrices are then used to compare existing flow parameters to possible new reservation classes as the terminal changes network access. In addition to presenting the mechanism, in this paper we detail the steps to construct the matrices. The construction of matrices are based on modeling the behavior of multiple classes of 4G traffic passing through different kinds of wireless IP domains implemented with different queuing and scheduling combinations.
