GSM, UMTS and LTE Advanced Overview - Radio Access Network & Core Network

Course Description

Introduction of LTE/4G technology will increase the demand for high capacity transportnetworks. This course meets the requirements from experienced professionals,dealing with operational and planning aspects of the mobile radio, core ortransport level. The course gives a detailed description of post-R99 systemarchitectures, their configuration options and additional features.

Multi-RAB options,Flexible Iu and S1 configurations for MOCN and pooled SGSN/MSC-S/MME and S-GWare explained. The new features for operator centric services, like PCRF andCSCF and IP enabled QoS across the UMTS and LTE core and radio infrastructuresare also described.

The evolution ofUMTS towards HSPA advanced and LTE is described in terms of systemarchitectures, protocols and operational features like self configuration andself optimization (SON).
