GSM/GPRS Infrastructure and Operation

  • Course Name: GSM/GPRS Infrastructure and Operation
  • Duration: 4 days
  • Technical Level: 4

Overview

Designed to give a thorough understanding of the Architecture, Protocols and Operation of the GSM and GPRS networks, this course explains the concepts and implementation of the network in detail. Presented in a clear concise format, this course explores the technology in a logical format, including the Radio Access Network, Core Network, and the required underlying systems. The protocols are examined in depth and signalling flows are used where necessary to illustrate the operation.

Each training session is thoroughly reviewed to help understanding, and with the aid of the trainer, delegates are asked to complete a network map showing how the interfaces, protocols, and each part of the architecture fit together the in overall system.

Course Objectives

  • Create a diagramatic representation of the GSM System Architecture, describing the role and basic operation of each element.
  • Describe the structure and main features of the GSM radio interface, understanding the options available in terms of voice coding, user data rates, resource allocation, and channel mapping
  • Explain the terms physical and logical channels as applied the GSM air interface and describe how logical channels are mapped to physical channels
  • Identify the role of each protocol in the GSM air interface stack
  • Follow and describe the basic GSM procedures, including mobility management, connection management and security functions
  • Explain the main issues regarding interworking with external networks, including the PSTN and other GSM networks
  • Discuss with confidence basic GSM procedures including Handovers and Location Updates
  • List the different protocols used within a GPRS network, describing the role each plays within the overall system and the interfaces to which they are applicable
  • Describe the structure and main features of the GSM GPRS radio interface, understanding the options available in terms of coding schemes, user data rates, resource allocation, and channel mapping
  • Follow and describe the basic GPRS procedures, including connection and location management, context activation and security
  • Explain the main issues regarding interworking with external networks, including the Internet, other GSM / GPRS networks (Roaming and the GPRS Roaming Exchange(GRX)), addressing issues and the provision of SMS over GPRS
  • Discuss with confidence potential GPRS services, including GPRS mobile devices and class of operation, quality of service issues, network rollout, billing options, and service concepts
  • Follow the core network signalling procedures for both simple service control and mobility scenarios in a GSM network
