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, IM and Presence. EPC and IMS support interworking with the existing 2G/3G wireless networks as well as PSTN to facilitate smooth migration, seamless mobility and service continuity across these networks. This eLearning module provides an overview of supporting voice services using LTE, which is known as Voice over LTE (VoLTE). The module discusses the LTE-EPC, IMS, and the PCC as the building blocks for VoLTE. The pre-call operations such as connectivity with the IMS network and IMS registration are explained, along with the VoLTE call setup and configuration. Interworking between LTE and PSTN is also discussed.

After completing this course, the student will be able to:• Describe how voice services will function in LTE networks using VoLTE• Describe the role of the LTE-Evolved packet core, Policy & Charging Control and IP Multimedia System (IMS) in LTE networks• Specify the role of key IMS and Policy nodes and how those nodes interact to deliver an end-to-end VoLTE call• Summarize the main steps of pre-call operations including default bearer establishment and IMS registration• Summarize main steps of pre-call operations such as IMS registration• Describe the main steps of setting up a VoLTE call• Identify the protocols used within the LTE and IMS networks for VoLTE
This course is an overview of Voice over LTE, and is targeted for a broad audience. This audience includes those in planning, Integration, operations, and end-to-end service deployment groups.
