LTE Failure Reporting and Troubleshooting Procedures
This hub groups the LTE paths that help explain where a procedure stopped, which branch failed, and which reference page to open next.

What This Covers
This category covers LTE failure-led reading paths rather than one normal success-only workflow.
Common nodes depend on the failed procedure, but most paths involve the UE, eNB, MME, and NAS state context.
These references matter when traces show a symptom but the real break point is still unclear.
Generic Protocol Error Handling
Procedures that explain how LTE handles generic protocol and content errors.
- LTE Generic Error Handling Procedure — Generic protocol error handling path.
- LTE ASN.1 / Encoding Error Handling — Failure path for encoding and decoding issues.
- LTE Mandatory Field Missing Handling — Error path when mandatory information is absent.
- LTE Unknown / Not-Comprehended IE Handling — Failure path for unsupported or not-comprehended IEs.
Failure Reporting
Procedures that report failures after LTE radio or multi-connectivity issues.
- LTE Failure Information Procedure — Failure reporting path after radio or procedure issues.
- LTE SCG Failure Information Procedure — Failure reporting for secondary cell group issues.
- LTE NR SCG Failure Information — NR-related secondary cell group failure reporting.
- LTE MCG Failure Information — Master cell group failure reporting path.
Recovery and Failure Analysis
Procedures that help classify the failure and choose the next analysis path.
- LTE Failure Type Determination — Determines the relevant failure branch and analysis path.
