Ralf Kreher Libros

Focuses on providing an overview and reference to UMTS UTRAN and Core networks. This work describes the details of the standards, the network architecture, objectives and functions of the different interfaces and protocols.

This comprehensive reference on call procedures for 4G RAN and Core networks delves into LTE signaling, troubleshooting, and optimization. It covers essential topics such as performance measurement counters, radio quality, user plane quality, standards, architecture, and the functions of various interfaces. The initial section provides an overview of LTE/EPC network architecture, reference points, protocol stacks, information elements, and elementary procedures. Subsequent sections address advanced topics, focusing on LTE/EPC signaling and radio quality analysis. By supplementing 3GPP standards, the book offers a universal LTE/EPC protocol sequence, enhancing the reader's understanding of network issues. It details normal signaling procedures and guides readers in identifying and troubleshooting abnormal network behavior and common failure causes. The text enables readers to grasp the signaling procedures and parameters necessary for monitoring UMTS networks, offering firsthand insights from real LTE/EPC traces. This reference is particularly useful for test and measurement experts analyzing LTE/EPC signaling procedures and measurements at a detailed level. Additionally, it includes descriptions of LTE air interface monitoring scenarios and other advanced topics, serving as a successor to previous works on UMTS signaling and performance measurement.
