4G LTE Access Procedures

This episode of Field Journal we’ll explore how devices connect, communicate, and use the Celona Edge to optimize connectivity and follow QoS instructions.

Check out the Episode 14 of Field Journal to get answers to questions like:

• How does QoS work over the CBRS spectrum?
• What are client access procedures?
• What is an Evolved Packet System (EPS) bearer?
• What are the Camp and Attach states for device connectivity?

Key Takeaways

• The UE Initial Access Procedure is broken down into two phases, Camp and Attach.
• The Camp phase conducts a frequency search across a spectrum band, and will sync on reference signals to begin decoding Management Information Blocks.
• The Attach phase uses an RRC connection to join and authenticate via the MME.
• Lastly ESP Bearer setup kicks off to establish end-to-end QoS policies.
