CBR-Based Resource Allocation for Multimedia Streaming Services in QoS Enhanced LTE/LTE-A Networks

Abstract

The LTE/LTE-A broadband cellular communication networks are expected to be quality-of-service (QoS) provisioning. The wide-spreading handheld devices with various free and easily downloadable applications make multimedia streaming services provided everywhere. Multimedia streaming data like video are compressed such that successive frames may have different sizes, and then each frame transmission is a burst with a different size. The service of delivering video is then classified as of variable bit rate (VBR). It is not easy for traffic control on VBR services. The resource utilization may be reduced if too much resource is reserved for a video stream, or video playing may be paused due to improper or less resource reservation. For these reasons, there has been some related work that makes video-on-demand (VOD) streams transmitted in constant bit rates (CBR). It will then reduce some overhead in traffic control and provide better quality of services. Besides designing suitable signaling protocols for resource reservation in LTE/LTE-A, accurate estimation of resource that should be reserved is another important topic for CBR-based transmission. In this paper, a feasible computation for minimal resource requirements is proposed for CBR multimedia streaming services in QoS enhanced LTE/LTE-A networks.
