Bandwidth Allocation Considering Priorities among Multimedia Components in Mobile Networks

摘要

This paper proposes a bandwidth allocation scheme which improves degradation of communication quality due to handoffs in mobile multimedia networks. In general, a multimedia call consists of several component calls. For exam- ple, a video phone call consists of a voice call and a video call. In realistic environments, each component call included in one mul- timedia call may have different requirements for quality-of-service (QoS) from each other, and priorities among these component calls often exist with respect to importance for communications.
