About
LTE, Long Term Evolution, as defined as Release 8 through Release 10 of the 3GPP specifications, consists of the eUTRAN and the SAE /EPC. There are a considerable number of protocols and signalling messages being passed during system operation, between Uu and eUTRAN as well as between eUTRAN and EPC.
This three day course describes the overall protocol structure before focussing on specific protocols. The protocols examined include LTE to Ue protocols including PDCP, RRC, RLC and MAC, the inter-eNodeB protocol X2, the S1 protocol between the E-UTRAN and the evolved packet core and the evolved GTP for LTE.
This course is intended for telecom professionals working in the areas of LTE hardware and software development, LTE system engineering and in the testing and verification field.
On completion of this course the delegate will be able to:
- Describer the use of S1-AP protocol for Non-Access Stratum Messaging
- Decribe the Initital Attach Request message
- Describe the use of GTP-C messaging between the MME & SGW

Training Methodology
Pathways Training and consulting adopts the newest techniques of human resources Training and consulting and, with the following:
- Theoretical lectures are delivered via PowerPoint and visual displays (videos and short films)
- Making scientific evaluation to the trainee (before and after)
- Brainstorming and role-playing
- Using case studies related to the scientific material being delivered and the trainees' work.
- The participants get the scientific and practical material printed and on CDs and Flash memories.
- Preparing records and reports of the participants' attendance and results, with a general evaluation of the training program.
- A group of the best trainers and experts in all fields and specialties professionally prepares the scientific material.
- After finishing the course, the participants get certificates of attendance signed, certified, and issued by pathways Training and consulting.
- Our training programs start at 9:00 o'clock in the morning and end at 2:00 in the afternoon, with snack buffet during the lectures.
- Providing a lunch buffet during the training program period, with organizing a lunch party on the training program final day for taking some photos and certificate awarding.
