5G-NR Call Flows
5G-NR Non Standalone Access Flow (EN-DC)
LTE support for 5G dual connectivity will enable 4G network operators to introduce 5G services with a minimual upgrade to support 5G data plane. This is achieved with the support for 4G eNB and 5G gNB dual connectivity (EN-DC).
5G-NR Standalone Access Registration Flow
As 5G gains momentum, the networks will transition to an end-to-end 5G solution with UEs registering with the 5G Core Network. The 5G standalone access registration signaling flow is similar to the 4G attach and default bearer establishment flow.
