• The course is intended for telecommunications engineers involved in the deployment of LTE/EPS networks.

LTE is one of the next generation wireless networks. It is designed to provide spectrum efficiency, additional capacity and a platform that supports the ever increasing demand of rich mulitmedia user-experience. As operators are getting ready for its initial deployment, they need to know the end-to–end call processing not only to effectively develop, expand or optimizie the EPS network architecture but also to troubleshoot the implementation and configuration issues.

This course provides step by step procedures performed by an LTE UE from when it is powered on to when it is ready to avail services through EPS networks. The course begins with an introduction of the Evolved Packet System (EPS) network architecture. It then discusses the use of subscription data during cell selection and EPS registration. The course stresses on the control messaging and parameter configuration on various interfaces in the EUTRAN and Evolved Packet Core (EPC) to facilitate registration with EPS network and establishment of EPS bearers. These bearers are used for transporting the user plane application data to external networks. QoS support, through dedicated EPS bearer setup and multiple PDN connectivity in EPS network is also covered. There is discussion of packet filters, packet marking, and relevant charging to explain user plane data through the EPS network. Finally, the course presents mobility in idle and connected states through measurement configuration, cell reselection and handover support.

After completion of this course the student will be able to:

• Describe the EPS network architecture, nodes and their functions
• Recognize the use of subscription information and LTE device capability to support PLMN selection, cell search, and camping
• Explain intra-frequency and inter-frequency cell reselection during Idle state mobility
• Explain page monitoring in idle state
• Describe the EPS Attach Procedure with mutual authentication support and security activation in EPS network
• Describe establishment of different bearers within EPS network to support transport of user plane application data
• Explain the UE and NW dedicated EPS bearer establishment to avail QoS
• Illustrate the support for connectivity to multiple APNs in EPS
• Describe the events configured to faciliate measurements in connected state and related reporting
• List different types of handovers in EPS based on the architecture and seamless data transport during handovers
• Describe different Radio Link failure scenarios and recovery mechanisms in connected state
