4G-5G Protocol Evolution


This course is day 4 of the 5G New Radio Specifications and System Design course and can be taken on its own or as part of the 5-day course.

This course presents a technical description of key 4G protocols and procedures through progressive releases of the 3GPP specifications since the introduction of LTE in Release 8. Protocol structures and mechanisms that support communications across various interfaces are presented, including the Air Interface, E-UTRAN, Core Network and EPC systems. S1, X2 and EPS signalling principles and example signalling procedures are presented and E-RAB setup mechanisms discussed. The course then presents the requirements and potential solutions that are currently being discussed for the development of 5G systems. The course also includes an overview of procedures relating to registration, security, mobility management, voice call setup and PS data session establishment for current LTE networks.
