VoLTE Optimization Training and Certification
Deploying a technology requires various optimization and troubleshooting steps to get full advantage of technology’s advantage.
VoLTE optimization and troubleshooting areas are divided into three major parts : VoLTE voice quality (check discards, check delays), VoLTE RF quality (TTI bundling enabling , RoHC implementation) and battery saving in the UE (efficient DRx). Cell load percentage in a cell is usually measured by number of users divided by max limit of eNB. Good RF ranges from -75dbm to -85 dbm and Bad RF ranges from -110 dbm to -125 dbm. In VoLTE, SIP and voice traffic packets are two main kinds of packets. VoLTE optimization process and steps include: performance optimization options, QoS requirements for VoLTE, LTE capacity planning and dimensioning, end user quality optimization, voice priority, third party applications, scheduling, header compression etc.
This course of VoLTE optimization covers the basic process of optimization of VoLTE networks. It covers VoLTE coverage and capacity optimization. Automated optimization of coverage, capacity, mobility performance of wireless networks do not only allow mobile users to enjoy HD voice and high speed broadband services . Automated radio network optimization includes : coverage and capacity optimization (CCO), mobility robustness optimization (MRO), root sequence index (RSI) and physical cell identity (PCI) optimization, Automated inconsistency correction (AC). IMS Analysis and optimization includes: probe based analysis, timer optimization, release cause analysis, IP network consistency check.
