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). LTE-EPC, IMS, and the PCC are discussed as the building blocks for VoLTE. The pre-call operations such as connectivity with the IMS network and IMS registration are explained along with VoLTE call setup and configuration. Interworking between LTE and PSTN is discussed.

The Internet Protocol Multimedia Subsystem (IMS) is a significant core network evolution that uses common Internet-based protocols to provide global, access-independent and standard-based IP connectivity and service control. The IMS architecture is a key enabler of various types of multimedia services to end-users. IMS helps provide a network that fulfills the promise of all-IP networks, allowing a combination of real-time and non- real-time services to be delivered to a single device. IMS is access network independent and, hence, promotes interoperability between wireline, cellular, WLAN, CATV, FTTH and other types of access networks. This course explores the various concepts used in the IP Multimedia Subsystem (IMS) including architecture, network components and interfaces. Please note that this course does not cover any specific access technology.

As the wireless industry transitions to 3G and 4G wireless networks supporting higher rate packet data services, a solid understanding of IP networking is essential. IP is to data transfer as a dial tone is to a wireline telephone. A fundamental knowledge of IPv4 and IPv6 networking along with use of VLANs is a must for all wireless professionals. Starting with an introduction to IP networking services such as the web, email and VPN to illustrate the value and ubiquity of IP networks, the course then describes the IP network architecture, the functions provided by various components and the role of key protocols. This course provides an introduction to IPv6 features, its interworking with IPv4, and techniques to migrate to IPv6 and concludes with a discussion of how GPRS/UMTS/LTE and 1x/1xEV networks take advantage of IP networks when providing mobile web access.
