Recent studies have shown that in LTE Uplink, the handshake procedure consisting of a scheduling request message from the User Equipment and a scheduling grant from the eNB required twice a communication over the air interface and caused notable delay. It could be harmful for loss and latency-sensitive applications such as Videotelephony traffics. So, we propose in this paper a new scheme which improves resource allocation for Videotelephony traffics and reduce the delay caused by Dynamic scheduling. The key idea is to schedule Videotelephony traffics using a Semi-Persistent strategy with Provisioning. The performance of our proposed algorithm have been evaluated in real LTE environments with LTE-Sim and simulations results demonstrated its effectiveness by showing that it optimized Videotelephony traffics performance and provided the best QoS support compared to the Dynamic Scheduling.
