LTE Core Network Training

LTE Core Network Training

LTE Core Network Training:

LTE Core Network Training Course (Online, Onsite, and Classroom Live!

LTE is a fourth-generation mobile communication technology standardized by the 3GPP which enables support for broadband connectivity to mobile devices, permitting the delivery of demanding multimedia information to any device, anywhere, anytime. In support of this, changes to the core network are also defined as System Architecture Evolution (SAE), providing an all-IP bearer platform for the delivery of services.

This LTE Core Network Training course will provide you with a comprehensive understanding of the development, design, and capabilities of SAE. The LTE Core Network Training course will begin with a review of UMTS and HSPA evolution and the architecture of LTE/SAE. An in-depth study of the SAE core entities and their functionality, the interfaces, and the protocols used over those interfaces follows. Signaling and NAS procedures, interworking scenarios, and services are described.

The focus of the course then shifts to transport options for the deployment of LTE/SAE as next-generation network infrastructure. Carrier-class MPLS is described in detail. The course finishes by examining transport options for access, backhaul, and core network.

Customize It:

  • If you are familiar with some aspects of LTE Core Network Training, we can omit or shorten their discussion.
  • We can adjust the emphasis placed on the various topics or build the LTE Core Network Training course around the mix of technologies of interest to you (including technologies other than those included in this outline).
  • If your background is nontechnical, we can exclude the more technical topics, include the topics that may be of special interest to you (e.g., as a manager or policy-maker), and present the LTE Core Network Training course in a manner understandable to lay audiences.


After completing this LTE Core Network Training course, attendees will be able to:

  • Describe the architectural structure of SAE and entity functionality
  • State the protocols used over the EPC interfaces
  • Describe procedures and signaling for bearer setup and release
  • Describe the relationship between EPC and IMS service delivery
  • Consider migration to SAE within your network
  • Describe carrier-class MPLS operations
