The LTE Service Architecture Evolution (SAE) Evolved Packet Core (EPC) network is an essential component of next generation mobile networks. The all IP EPC in conjunction with the IP multimedia subsystem (IMS) supports voice and video. This course provides a detailed analysis of the architecture, interfaces, protocols, QoS and deployment of EPC.
EXPECTED ACCOMPLISHMENTS
- Outline the architecture and interfaces of E-EUTRAN and the EPC
- Characterize the performance capabilities of LTE/SAE system
- Discuss the different services offered by EPS and their impact on traffic and signaling
- Outline the key protocols used for control and user traffic
- Explain the procedure for EPS bearer establishment and service data flow
- Explore options for implementing voice in LTE (VoLTE, CSFB, OTT)
On completion of the course, participants will be able to apply this knowledge in LTE core network operations, and IMS interworking.
Engineering professionals involved in the Planning, Deployment, Optimization, and Operations & Maintenance of LTE Evolved Packet Core Networks.
TARGET AUDIENCE
Managers, Engineers, and Technicians involved in the planning, deployment and maintenance of mobile networks
