NSA Access Signaling: Failures Possible Causes & Troubleshooting (NSA Series#1)

This video is part of the Non-Standalone series, where we will cover signaling call flow, Troubleshooting guides, 5G traffic increase, insights on how to detect low-traffic sites, and the top 5G NSA features.

In this video, we'll deep dive into NSA Access Signaling, specifically focusing on SgNB addition signaling and all related aspects. We will explore potential failures, their causes, and effective troubleshooting methods. The following is covered in this video:

1- NSA(ENDC) Network Overview
2- 5G Secondary Node Addition procedure
3- Signaling Key Information elements Contents
4- NSA Troubleshooting Guide: Identification of Accessibility Issues

LTE Attach Procedure | E2E Call Flow, MME, EPS Bearer & Default Bearer | 4G E2E Signaling Session 5

Session 5 of my 4G/LTE E2E Signaling series is out: the LTE Attach Procedure. Attach is the first thing a phone does on an LTE network. It registers, gets authenticated, receives an IP address and sets up the Default EPS Bearer. In this session: → Attach Functions & Triggering Conditions

RACH CBRA/CFRA Call Flow and Use Cases

Overview The Random Access procedure can be initiated in different situations depending on whether the network already knows the UE and whether dedicated resources can be assigned. Random Access Channel, or RACH, is used whenever the UE needs to establish or recover uplink synchronization with the network. In 5G, Random
