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
4G LTE Cell Selection Explained: Initial Selection, Stored Information and Cell Selection Criteria
Introduction After the UE completes system information acquisition, the next step is to determine whether the detected cell is suitable for camping. This process is called cell selection. During cell selection, the UE checks the available LTE cells and evaluates whether a cell satisfies the required coverage, quality, and access
5G PDCCH Optimization Approach: Understand DCI Applications, CSS vs USS and What Is Consuming PDCCH Resources
Introduction When PDCCH utilization becomes high, the first question should not immediately be: Which PDCCH optimization feature should I enable? A better starting point is to understand what the PDCCH resources are actually being used for. PDCCH is involved in different procedures such as SIB1 transmission, Other System Information, Random
