GPRS Mobility (e) *RETIRED*

GPRS is the technology that provides packet data access to the existing GSM networks. It is designed to support an efficient mobile packet network. One of the greatest advantages of GPRS is that it allows a subscriber to access data services at a higher data rate while on the move. Therefore, mobility is a key requirement for wireless data networks. This course explores the issues of providing mobility within the GPRS network, such as how the mobile moves from cell to cell, as well as from Serving GPRS Support Node (SGSN) to SGSN. Roaming issues for packet data services are explored as subscribers move beyond their home service provider’s coverage area. GPRS has specified GPRS Roaming Exchange (GRX) to enable data roaming between operators. By the conclusion of this course, both equipment manufacturers and services providers will have an understanding of all the issues involved in packet data mobility.

Learning Objectives

After completing this course, the student will be able to:
• Describe the radio mobility aspects of GPRS
• Describe the requirements of location management within the GPRS network
• Explain the mobility management messaging used to support mobility in GPRS
• Describe the use of Access Point Names (APN) in GPRS roaming
• List the signaling and security requirements of inter-operator roaming
• Define the GPRS Roaming eXchange (GRX) and its use in the GPRS network

Intended Audience

This course is intended for those seeking a detailed understanding of the processes of signaling and mobility management for calls or packet sessions. This includes those in a design, test, systems engineering, sales engineering, network engineering, or verification role.
