Exploring LTE: Signaling and Operations - Part I
LTE_128Ad | On-Demand | LTE and VoLTE | 1
Course Duration: 1.5 hours
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 module is part one of the two-module package. Together, these two modules describe each of the key LTE operations, 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.
