Mastering UMTS Radio Protocols and Signaling

This course covers all the key aspects of the UMTS (WCDMA) Terrestrial Radio Access Network (UTRAN) – as deployed by major wireless operators and provides the details of the UTRAN architecture, protocols, operations and services. The signaling protocols and physical layer functions are introduced through following the end-to-end messaging of signaling initation and a voice call. Details of power control and mobility are presented followed by packet data scenarios that introduce the protocols (e.g., MAC, RLC), transport format sets and the basics of radio resource management. The final chapters include an overview of RF design and and introduction to HSPA. The approach of using end-to-end scenarios shows the application of concepts and the theory behind the concepts. In addition to review questions for each chapter, many of the in-depth chapters have classroom exercises that examine real world drive test logs.

Learning Objectives

After completing this course, the student will be able to:
• Identify the role of the UTRAN in delivering UMTS (WCDMA) services
• List the components of the UTRAN and their roles and responsibilities
• Describe the roles of control plane protocols (RANAP, RNSAP, NBAP, and RRC)
• Identify Uu and Iu interface messages
• Specify the physical layer functions and procedures managed by the UTRAN
• Define the details of system acquisition, initialization and authentication of the UE
• Explain the functions and procedures of logical, transport and physical channels
• Step through various handover scenarios including inter-radio access technology (UMTS to GSM)
• Highlight the procedures that support intra- and inter-UTRAN mobility
• Explain the steps of setting up and maintaining an RRC connection
• Explain the evolution of UMTS to HSDPA/HSUPA

Intended Audience

This course is primarily intended for a technical audience, including those in RF engineering, systems engineering, network engineering, product support, operations, and anyone seeking a more in depth understanding of the UMTS RAN.
