VoLTE For Radio Engineers - Mobility Optimization and EPS Signaling

Course Description

The training “VoLTE with IMS, EPS Signaling and Optimization of Mobility” has been tailored to suite experienced radio engineers. In addition to the VoLTE/IMS parts, extra content is introduced regarding Mobility functionality and associated parameters necessary to establish a foundation of a well optimized radio network for the VoLTE service to perform optimally. Furthermore, the necessary EPS Signaling is presented. Emerging technologies, systems and platforms are high-lighted. The below listed topics will be discussed and analyzed as they emerge during the course of the training
