Abstract: IP-based transport faces a number of challenges in QoS and mobility managementin order to meet the stringent transport and control requirements of 3G radioaccess networks. A framework of QoS support in IP/MPLS-based radio accessnetworks is proposed. Combining QoS routing with dynamic resource allocation,simulation results show that this can provide a suitable framework of QoSsupport in radio access networks. Moreover, a hierarchical MPLS-basedmicromobility scheme is proposed. By introducing one more level of hierarchy,optimal forwarding path is used for data packets upon handover. Theinteroperation of such micromobility scheme with Hierarchical Mobile IPv6 isdescribed and simulation results show that this approach improves handoverperformance, in terms of handover latency and packet loss.
