Voice over Long-Term Evolution (VoLTE) has been witnessing a rapid deployment by network carriers worldwide. During the phases of VoLTE deployments, carriers would typically face challenges in understanding the factors affecting the VoLTE performance and then optimizing it to meet or exceed the performance of the legacy circuit-switched (CS) network (i.e., 2G/3G). This course is a technical optimization of the VoLTE network. The course includes VoLTE Architecture and Protocol Stack, procedures in VoLTE performance optimization, Voice Call Continuity (VCC) features, VoLTE call dedicated bearer setup, Radio Network Optimization, and Voice Quality Optimization
