2G & 3G Training

Pre-Learning is provided to prime those attending the instructor led phase. Each lesson is based on an interactive online format and should take about 30mins to complete. The pre-Learning lessons are:
Lesson 1 Mobile Network Basic Architecture.
Lesson 2 Mobile Network Basic Procedures.
Lesson 3 Wi-Fi Operation.
Lesson 4 Wi-Fi Architecture.

The tutorial element of this course is instructor led. Divided into 10 sections covering:
1. Introduction
This section introduces the concepts behind UMA and outlines the benefits of supporting such a strategy for both residential and enterprise customers. It also reviews the different unlicensed elements - Wi-Fi and Bluetooth.
 2. UMA Network Architecture & Identities
This section details the elements which comprise the UMA network; GANC, SEGW and AAA Server prior to explaining how they interwork with GSM/GPRS & UMTS. Mode Selection and UMA Identities are also explained in addition to discussing the issues that affect UMA network planning.
 3. The Air Interface
Focusing on the 802.11 specification, this section explains the format of the Air Interface, in addition to outlining the procedures undertaken by the mobile as it authenticates and associates with an Access Point.
 4. Wi-Fi Quality of Service
In order to support multimedia applications such as voice and video, Wi-Fi may need to support QoS. This section explains how these applications may be supported through the access mechanisms EDCA and HCCA as detailed in 802.11e.
5. UMA Security Procedures
The principles of security are discussed in this section along with an explanation of digital certificates (X.509) and PKI. IPSec procedures are explored with respect to UMA operation before describing the authentication method EAP-SIM / AKA.
 6. UMA Operation
This section explains how the mobile conducts the Discovery and Registration procedures with the GANC. In so doing, real network traces are used to relate these procedures to the Generic State Model.
7. Circuit Switched Operation
In this section, the procedures of initiating a connection with the network and establishing both a mobile originated and terminated call setup are explained. This also includes a description of AMR and RTP/RTCP as it relates to UMA. This section is enhanced through the use of real network traces.
8. Packet Switched Operation
The establishment of a GA-PSR Transport Tunnel is explored in this section along with the methods of transferring both connection orientated and connectionless packet data. This section is also supported with real network traces.
9. UMA Mobility
The terms Rove In / Out are explained in this section in addition to describing the procedures of handing a call between Wi-Fi and GSM / UMTS. In so doing, the handover criteria are discussed as well as the issues affecting emergency services.
10. Future Enhancements
The final section explores the development of UMA and its ability to support interworking with other networks. Further, the 3GPP R4 architecture is discussed in terms of a “soft” GANC and alternate radio links are reviewed - WiMAX.
