LTE (Long Term Evolution) uses the Evolved Packet Core (EPC) architecture, a distributed and unified IP-based core network, to efficiently deliver Internet services to mobile wireless subscribers. This course describes typical LTE network architecture and deployment strategies, as the starting point for understanding the planning and design principles for the EPC. Students build up a network call model, determining the node and interface requirements needed to support the expected user traffic and signaling demands. Subscriber traffic demand, basic LTE operations, mobility and idle state functions, and interworking scenarios are all factored in to the model. Finally, redundancy and load balancing considerations are factored in, resulting in a network design that meets the market’s needs. This certification workshop includes several hands-on exercises and concludes with a certification assessment.
Learning Objectives
After completing this course, the student will be able to: • Define the key components of the LTE-EPC network models and determine the necessary inputs and expected outputs • Describe the logical and physical LTE network architecture • Create a subscriber demand (traffic) model and estimate the impact on the EPC user plane • Map typical LTE signaling operations to the corresponding nodes and interfaces and model their impacts on the EPC control plane • Quantify the impact of IMS and PCC services on the EPC user and control planes • Use the resulting network model to design an EPC network capable of supporting the subscriber demand
Intended Audience
This course is designed for network engineers, architects, and managers involved in planning, design, deployment and operation of LTE-EPC networks.
Suggested Prerequisites
