5G Core Network Signaling and Operations Part 6: Mobility and 4G Interworking
- Course Length:
- 4 hours
This is the sixth course in a six-course set of self-paced courses encompassing 5G Core Network Signaling and Operations! In this course, you will learn about both connected and idle mobility in 5G SA as well as the fundamentals of interworking operations between the 5G core and the LTE EPC. You will explore the signaling for handovers in 5G be they between cells on the same gNB or on different gNBs as well as the signaling for both idle and inactive modes in 5G. Finally, you will gain an understanding of handovers between an LTE network and a 5G network.
