VoLTE

( Duration: 2 Days )

This VoLTE QoS training course covers how LTE networks support end-to-end QoS for different IP-based services such as voice, video, multimedia messaging, and gaming. QoS in LTE Radio, EPC, LTE Backhaul and Core Network, PCC (Policy and Charging Control), EPS Bearers, policy, QCI for voice and video applications. Voice over LTE will play a key part in determining a subscriber’s Quality of Experience (QoE) on a LTE/EPC/IMS network.
