LTE Signaling, Troubleshooting, and Optimization

The emphasis of this book is describing the signaling procedures and call flows on the radio interface, in E-UTRAN and within Enhanced Packet Core networks. We discuss the most common failure scenarios for live network troubleshooting. We also highlight essential performance measurement counters and define industry-adopted KPIs for accessibility, retainability and mobility. A large section covers in detail how to measure radio and user plane quality, especially over the air interface. All of this includes practical examples from Tektronix Communications measuring equipment, the radio interface tester K2Air and the Network and Service Analyzer platform NSA.
