1xEV-DO Rel 0 Overview AND 1xEV-DO Rev A Overview or equivalent knowledge.

For a CDMA operator deploying LTE, understanding eHRPD and interworking is as important as understanding LTE itself.

As 3GPP2 operators being to consider migrating their existing CDMA2000 1X and 1xEV-DO networks to Long-term Evolution (LTE) networks, an intermediary step must be taken to upgrade the existing core network to make it ready for LTE, which is known as eHRPD.

This course provides an in-depth understanding of what eHRPD is and why it is important for a 3GPP2 operators’ LTE deployment. The main purpose of eHRPD is to provide interworking between the LTE network and the CDMA2000 network (1X/1xEV-DO). The network architecture evolution that occurs with eHRPD will be discussed in detail along with the various call processing examples, attach procedures, mobility and interworking scenarios. Device/handset modifications and behavior changes, including multimode system selection will be discussed in detail as well.

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

• Describe the evolution of 3GPP2 and 3GPP technologies
• Define and explain the eHRPD market and technology drivers
• Describe deployment strategies and network requirements for eHRPD
• Describe the LTE air interface capabilities and compare them to 1xEV-DO
• Describe the eHRPD network architecture, elements, and interfaces
• Identify and describe the interworking scenarios between eHRPD and LTE
• Describe the differences between the 3GPP and 3GPP2 interworking architectures
• Explain eHRPD packet session management, authentication, and IP allocation
• Describe the various mobility scenarios for active and idle handoffs
• Identify the capabilities of a multimode eAT, system selection and CS-fallback
• Identify the features and capabilities of 1X and LTE voice services interworking
• Describe the IMS architecture and Voice Call Continuity (VCC/SRVCC)
