GSM/UMTS/EPS System Overview

GSM/UMTS/EPS System Overview

The GSM/UMTS/EPS System Overview course describes the evolution from the voice centric GSM via the IP bearer of GPRS and early UMTS to the all-IP architecture in IMS and later developments such as High Speed Packet Access and LTE.  All topics are presented in a comprehensive – yet easily understandable – way. Essential subsystems, nodes and protocols are described. Basic traffic cases are used to demonstrate the function and architecture of the different systems.

Day 1 and 2:

• Nodes and architecture of GSM

The GSM Radio Interface

• Time Division Multiple Access (TDMA)
• Time slots, physical and logical channels
• Radio related problems and solutions in GSM

Cell Planning

• Cell types (macro, micro, pico)
• Coverage vs capacity
• General steps in the cell planning process

Mobile Station and BSS (GERAN)

• Mobile Equipment (ME) and Subscriber Identity Module (SIM)
• Base Station System: BTS, BSC

The Core Network

• Core Network nodes: MSC, GMSC, VLR and HLR
• SS7 signalling in the GSM Core
• The Split Architecture

Selected Traffic Cases

• Location Updating
• Call setup for roaming and non-roaming scenario
• Pre-paid and CAMEL
