LTE Failure Reporting and Troubleshooting Procedures
LTE failure reporting and troubleshooting procedures help identify where a call flow stopped, which error branch was used, and what recovery path applies. Use this hub to jump into protocol error handling, ASN.1 issues, mandatory field errors, unknown IE handling, Failure Information, SCG failure, MCG failure, NR SCG failure, and failure type determination call flows.

What This Covers
LTE failure reporting procedures show how protocol errors, encoding issues, missing fields, and unknown IEs are handled.
SCG, MCG, NR SCG, and Failure Information flows help classify radio, dual-connectivity, and recovery-related failures.
Use the links below to jump directly into error handling, failure reporting, failure type determination, and recovery call flows.
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.
