GSM, GPRS and EDGE Protocols and Signaling

The Global System for Mobile Communication (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rate for Global Evolution (EDGE) are the most dominant mobile wireless technologies. The 2nd generation GSM, was primarily designed for voice and text messaging services. Access to Packet data networks became possible with GPRS and EDGE which have significant impact on the network architecture, protocols and signaling aspects. This course provides the details of the Layer 2 and 3 procedures and signaling in GSM, GPRS and EDGE, taking a handset-centric point of view. After a detailed look at the GSM call-processing, we go on to show how the Layer 2 and 3 procedures of GPRS and EDGE allow efficient access to IP based networks.

Learning Objectives

After completing this course, the student will be able to:
• Describe the GSM, GPRS and EDGE technologies from a protocols and procedures perspective (L2,L3)
• Explain the role and function of the L2/L3 protocol stacks in GSM and EGPRS - (G)MM, SM, CC, SMS, SS,
• Describe details of Layer 2 (RLC/MAC) operations in EGPRS such as TBF setup, release and retransmissions
• Sketch the signaling call-setup signaling steps in GSM
• Sketch the attach and session setup signaling procedure in EGPRS
• Explain the role of APN, GTP, and QoS in EGPRS
• Describe the role and operation of IR in EGPRS

Intended Audience

This course is intended for those seeking a detailed understanding of the GSM, GPRS and EDGE protocols and signaling procedures involved in call processing. This includes those in a design, test, systems engineering, sales engineering, network engineering, or verification role.

Suggested Prerequisites

• Welcome to GSM/GPRS (eLearning)
