3G training course description

This course is designed to give the delegate an understanding of the technologies used within a 3G UMTS mobile network. During the course we will investigate the UMTS air interface and the use of Wideband-Code Division Multiple Access (WCDMA) to facilitate high speed data access, together with HSPA to offer mobile broadband services. We will describe the use of soft handover rather than hard handover procedures and soft capacity sharing. The course includes a brief exploration of the UMTS protocol stack and the use of PDP Context and QoS support features.

What will you learn

• Explain the 3G UMTS architecture.
• Describe the role of a Drifting & Serving RNC.
• Explain the use of ARQ & HARQ for mobile broadband.
• Describe how IMS integrates into the architecture.
• Describe the use of Media Gateway Controllers.
• Identify the temporary identities used within 3G UMTS.
