Analyzing the UTRAN

This course is a deep dive into the details of the 3G UTRAN, starting with the key interfaces and protocols involved. The use of IP transport in the UTRAN is also explored, along with the composition of the air interface in terms of the different channel types used. Focus is then turned to the Node B, detailing the setup, configuration and synchronization aspects of the platform. After analysis of the various UMTS connection states, the course will examine both circuit and packet switched operation, before concluding with a breakdown of mobility related procedures.
This course will contain the following sections:
