The problem how to improve the quality of server(QoS) of the heterogeneous network must be studied and solved, for long round trip times (RTTs), not negligible packet error rates (PER), and downlink-uplink asymmetry, etc. Posing new challenges to the QoS given by transmission control protocol (TCP). the paper proposes a Diff-selective(diff-sel) policy, which can solve the problem by selecting different...
In this article new architectures for network- assisted management of vertical handovers are proposed, relying on IP-based protocols, aiming at achieving the most relevant intersystem mobility decision with respect to user satisfaction and operator added value. The key design principle used is ease of deployment, with flexible hierarchical handover decision entities allowing the distribution of the...
