LTE Optimisation Workshop
The LTE Optimisation Workshop training gives understanding of how the Evolved UTRAN (E-UTRAN) performance is monitored by 3GPP specific Key Performance Indicators (KPIs) and how to optimise the E-UTRAN performance by use of Long Term Evolution (LTE) parameters.
First, the Evolved Packet System (EPS) architecture is presented together with the EPS nodes functions. Also the LTE protocols architecture is explained with the distinction between transport and signalling protocols, Access Stratum (AS) and Non-Access Stratum (NAS), User Plane (UP) and Control Plane (CP). The EPS UP and CP protocol stacks are presented with emphasis on the radio interface.
Next, the fundamental concept of the EPS bearer and Quality of Service (QoS) is explained. The default and dedicated EPS bearer setup process and its interworking with Home Subscriber Server (HSS) and Policy and Charging Rules Function (PCRF) nodes is shown.
The training also explains the concept, range and usage of RSPR, RSRQ and SINR for coverage verification, signal strength and signal quality analysis.
The essential part of the training contains the definition of the KPIs for Accessibility, Retainability, Integrity, Availability and Mobility together with the Performance Measurement (PM) counters used in the KPIs as defined by the 3GPP. The counters are illustrated in the flow graphs. For better understating of the KPI formulas, they are calculated with use of an Excel spreadsheet for a sample cell.
The training focuses on explanation of the LTE procedures, functions and parameters, which are used to improve the KPI performance. Also live network log-files are analysed for in depth understanding of the parameters structure and usage.
