Course title 3GPP LTE Signalling
 
Course description This 3 day course covers LTE Signalling as specified by 3GPP release 8.
After a review of the LTE system architecture as well as E-UTRAN basic functions and protocols, the course will focus on signalling procedures. The protocols and procedures will be described in detail per interface, starting with the radio interface, including the RRC, PDCP, RLC, MAC and PHY protocols, continuing with S1, X2, S11, S10 as well as S5/S8, hence also including some SAE interfaces as well, where focus will be on the upper layers. Thereafter the NAS protocol, between UE and MME will be introduced, including a detailed description of the Attach and Tracking area update procedures. With detailed knowledge about the various protocols, procedures covering a number of interfaces will be described, such as security, handover and examples of different services.
 
Who would benefit Anyone who is working, or will be working, with LTE/SAE and requires a thorough understanding of the signalling and related protocols and procedures.
 
Prerequisites Basic knowledge of LTE/SAE is compulsory.
