Voice & IMS in LTE-EPC Networks


The LTE Evolved Packet Core (EPC) is an evolution of the 3GPP system architecture with the vision of an all-IP network finally realized.

EPC in conjunction with IP Multimedia Subsystem (IMS) delivers various services such as VoIP, SMS, Video call, Picture share, Instant Messaging and Presence.

EPC and IMS support mobility with the existing 2G/3G wireless networks as well as PSTN to facilitate smooth migration, interworking and service continuity across these networks.

This course provides a detailed look at the architecture of the LTE-EPC Networks, IMS and QoS framework to deliver end-to-end voice (Voice over LTE – VoLTE) in LTE networks.

It also covers various service scenario walk-through that utilize IMS and EPC networks components.

The IMS service architecture and the interaction with existing services are described.
