GSM Air Interface
- Course Name: GSM Air Interface
- Duration: 2 days
- Technical Level: 4
Overview
From basic radio principles to detailed signaling sequences, this course explains the mechanisms behind the GSM radio interface. The GSM air interface is described here, first in general terms, examining the 'channels' used by the mobile and the network to establish communications, then with increasing detail, the procedures and messages exchanged between the peer layers of the GSM protocol stack.
Course Objectives
- Identify which part of the radio spectrum GSM operates in and explain what is meant by the term Radio Channel
- Describe the Logical Channels and how they are mapped onto Physical Channels
- List the basic requirements for a GSM mobile at Idle Mode
- Show how the mobile may 'sleep' for periods of time whilst in Idle Mode
- Explain the process of measurement taking and measurement reporting that the mobile is required to carry out whilst in dedicated mode
- Show how the network supports the handover procedure
- Draw the GSM protocol stack and explain briefly the function of each sublayer
- Show on a signaling sequence diagram the elementary procedures used by the GSM mobile
Course Requirements
An understanding of mobile radio networks and basic telecommunication procedures would aid the delegate attending this course.
