Common channel signaling and GPRS protocols knowledge and TCP/IP and ATM protocols good understanding.

Course Content

Detailed protocol tracing analysis, with particular focus on the messages exchanged between network elements during UMTS Voice calls and Data transmissions. Thanks to this kind of study, it will be easier to understand each 3G network signal flow.

Course Objectives

This course aims to provide trainees with specific knowledge on UMTS mobile network signaling protocols. Thanks to a signal flows depth analysis it is possible to fully understand the meaning of each signal message sent from and to access equipment and core network exchanges, concerning both UMTS voice or video calls, and 3G or 3.5G High Speed data.
