The Long Term Evolution (LTE) network is designed to deliver services and content to mobile subscribers quickly, efficiently, and with high quality. In order to achieve this goal, the various elements within the network communicate with each other and with the mobile device using well-defined protocols and procedures to accomplish the various tasks and operations required. This self-paced eLearning class describes each of the key LTE operations in turn, starting with the mobile’s initial access to the system, followed by the steps needed to connect users to their services and content, and continuing with the challenges associated with maintaining the connections as the user moves through the network. The course concludes with a discussion of the mobile’s idle mode activities and the low-level operations needed to maintain the radio link. Frequent interactions are used to ensure student comprehension at every stage.

This course is intended for a technical audience looking for an in-depth understanding of the important signaling sequences and detailed operations used in a typical LTE network

After completing this course, the student will be able to:
• Describe how a UE accesses the LTE network on initial power-up
• Explain the steps involved in attaching to the network and establishing PDN connections
• Explain how user traffic is exchanged over the air interface under varying radio conditions
• Define the physical layer functions needed to maintain an active radio connection
• Discuss the methods used to track the mobile’s location and maintain its active connections as it moves through the network
• Describe the tasks the mobile must perform while in idle state
