Course Objectives
This training concentrates on the LTE/EPS Non-Access Stratum (NAS) Signalling i.e. signalling procedures that runs transparently between UE and MME.

Pre-requisites
The participants should have attended the EPS/LTE/SAE Technology course or or should have the equivalent knowledge. Practical experience in GSM/GPRS/UMTS protocols would be recommended.

Training Structure
1-day training.

Methodology
Instructor led training.
