Abstract	This work presents a QoE-based interworking call admission, handoff, and packet scheduling system to provide a seamless multimedia streaming services over LTE network. First, QoE metrics are defined based on the amount of buffered frames at the video decoder buffer. Based on these QoE metrics, the proposed call admission algorithm estimates the cell idleness at the next call arriving time to determine the admission of a new UE and the proposed handoff algorithm determines the appropriate handoff trigger timing to keep a balance of the QoE satisfaction levels among immediately adjacent cells. The proposed packet scheduling algorithm has designed in consideration of both the QoE satisfaction levels and the wireless link states of all admitted UEs. Finally, experimental results indicate that the proposed interworking system improves the QoE satisfaction levels of all admitted UEs and overall network utilization better than other existing methods.
