What is S1AP in LTE

(71-1513) LTE EPS (Evolved Packet Core)

LTE EPS Evolved Packet System

During this course, participants learn about the EPS Evolved Packet System - the mobile core with nodes: MME, HSS, PCRF, SGw, PGw, IMS. Together with signaling and security procedures: authentication and encryption.

Participants learn how to connect to the QoS bearer and gain access to the Internet and IMS. All important network protocols and signaling methods are explained in detail.
