VoLTE QoS Training | VoLTE Quality of Service 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, and QCI for voice and video applications are covered. Voice over LTE will play a key part in determining a subscriber’s Quality of Experience (QoE) on an LTE/EPC/IMS network. VoLTE QoS Training covers all the QoS and QoE features in LTE and LTE-A to support VoLTE. One of the major challenges associated with Voice over LTE (VoLTE) is defining the Quality of Service (QoS)  features for the LTE RAN, EPC, and IMS.

LTE Application layer level performance is important and the QoS prioritization of the voice element has to be accurate. VoLTE is positioned as a high-quality voice service enabling call quality on LTE, EPC, and IMS networks. The challenge is to ensure User Equipment (UE), Radio Access Network (RAN), Evolved Packet Core (EPC), and IP Multimedia Subsystem (IMS) core are optimized to deliver the best quality of service aligned with the SLA and policies.
