This course focuses on the interworking between LTE and 1xEV-DO, a.k.a. evolved High Rate Packet Data (eHRPD) from the perspective of the network. The course first identifies interworking performance targets and challenges, and provides a glimpse of interworking scenarios. An overview of the network architecture follows with a discussion of the roles of entities such as the HSGW and eAN. The initial eHRPD access by a UE is discussed at length, including a description of the new EAP-AKA based authentication and new IP address allocation methods. Establishment of main and auxiliary connections for an eHRPD access is shown, along with multi-PDN connectivity and implementation of QoS with cohesive 3GPP and 3GPP2 QoS definitions. Both active mode mobility and idle mode mobility are considered, as well as optimized and non-optimized interworking scenarios. Interworking for CS voice calls is also explained.
Learning Objectives
After completing this course, the student will be able to: • Sketch the LTE-eHRPD interworking architecture • List performance targets and challenges for LTE and 1xEV-DO interworking • Identify the impact of interworking on LTE and 1xEV-DO network nodes • Explain the basic steps of default PDN connectivity for an E-UTRAN access • Describe mobility procedures from LTE to eHRPD • Explain the basic steps of default PDN connectivity for an eHRPD access • Describe mobility procedures from eHRPD to LTE • Discuss the implementation of QoS • Summarize the main steps of active mode and idle mode mobility • Contrast optimized mobility with non-optimized mobility • Explain interworking between LTE and 1xRTT for Circuit-Switched voice calls
Intended Audience
