VoLTE Performance Optimization Training

VoLTE Performance Optimization Training course teaches you the concepts and techniques of VoLTE Performance Optimization. This hands-on training covers Analyzing Signaling Protocols, VoIP Client Options, Radio Network Optimization, EPC Optimization, Voice Quality Optimization and UE Power Consumption Optimization.


What is VoLTE and What Does it Do?

Mobile operator networks transfer tens of billions of minutes of voice traffic every day, the majority of which using Circuit Switched (CS) voice in 2G and 3G technologies. Most LTE operators provide voice calls through “CS-fallback function”, whereas several operators have already made the switch to Voice over LTE (VoLTE). The VoLTE offers a carrier grade Voice over IP (VoIP) solution, built on IP-Multimedia Sub System (IMS) architecture.

VoLTE offers several advantages for operators and end-users including (but not limited to):

  • Improving LTE radio spectral efficiency and offering High Definition (HD) voice quality
  • VoLTE can use LTE on low frequency spectrum
for good coverage, delivering fast call setup times and enabling LTE data rates during the voice call.
  • IMS architecture is the foundation for new, groundbreaking carrier-provided end-user multimedia services.

Importance of VoLTE Optimization

Positioning VoLTE needs a number of optimization steps to achieve the complete benefit of the technology’s potential.

A VoLTE solution has synergies with Voice over Wi-Fi (VoWiFi), where operator voice can be run over Wi-Fi radio. If evolved packet core is enhanced with evolved Packet Data Gateway (ePDG), the VoWiFi can be reflected as a VoLTE extension. So, it offers seamless handovers between the LTE and WiFi accesses, also involving mobile handset support.

The number of VoLTE placements is growing fast, with a broad alternative of handsets, including iPhone 6, which also covers VoWiFi.

Three Voice Options for Quality and Efficiency

  1. Native VoLTE client included in the handset chip set. The number of commercial handsets with native VoLTE clients is increasing fast.
  2. Non-native VoLTE clients. Third party applications, which can register to IMS (IP Multimedia Subsystem) and set up VoLTE call using QoS (QCI1).
  3. Over-the-Top (OTT) VoIP applications such as Skype, Facetime and Viber.
