What is 5G ENDC? - RCR Wireless News
WEBMay 3, 2022 · ENDC has been described as a bridge between 4G LTE and 5G cellular technologies. ENDC, or E-UTRAN New Radio – Dual Connectivity, is a Non-Standalone (NSA) feature that makes it possible for mobile devices to access both 5G and 4G LTE networks at the same time, which allows carriers to tap into the benefits of both network technologies simultaneously.
LTE Attach Procedure Call Flow-Break the Big Picture into Small …
WEBMay 9, 2014 · Here’s the LTE Attach Procedure Call Flow, broken down into steps, derived by 3GPP. Step 1. The UE initiates the attach procedure by transmitting an attach request to the eNodeB. Step 2. The eNodeB derives the MME from the RRC parameters carrying the old GUMMEI and the indicated Selected Network. Step 3.
Understanding FDD/TDD carrier aggregation for 5G - RCR …
WEBApr 20, 2021 · In general, FDD is considered better for coverage and TDD better for capacity. Mobile operators are looking to carrier aggregation (CA), which allows them to use multiple sub-6 GHz spectrum channels simultaneously, as a method of increasing the bandwidth and speeds of their 5G networks. However, to enhance the performance of 5G networks even ...
What is 5G VoNR? - RCR Wireless News
WEBFeb 21, 2022 · Unlike its predecessor Voice over Long Term Evolution (VoLTE), 5G VoNR removes the LTE anchor allowing the voice call to stay on a 5G network from the UE, through the RAN and core. 5G voice calls are implemented as end-to-end Voice over IP (VoIP) connections managed by the IP Multimedia System (IMS) core; IMS is an architectural framework for ...
How are operators using 5G Standalone in the real world?
