What is Remote UE Report in LTE?
It is the LTE NAS message the UE uses to send remote UE or CIoT report information toward the network.

Remote UE Report is the LTE NAS message used in remote UE or CIoT handling to report remote-device status or event information toward the network.
Carries report information from the UE side so the network can process remote UE or CIoT-related status and event reporting.
Remote UE Report is the LTE NAS message the UE uses to send remote UE or CIoT report information to the network.
Call flow position: UE-originated NAS report used to send remote UE or CIoT event information toward the network.
Typical state: The reporting branch is active and the UE is providing event or status data.
Preconditions:
Next likely message: Remote UE Report Response
Previous message(s): Remote UE Report Response, Control Plane Service Request
Next message(s): Remote UE Report Response
Security context: Usually protected because it appears in an active NAS context.
Remote UE Report
Remote UE report container
Additional information OPTIONAL
Read the report container first and then identify the wider remote UE or CIoT branch.
Remote UE Report
Protocol discriminator: EPS mobility management
Security header type: Integrity protected and ciphered
Message type: Remote UE Report
Remote UE report container: status report
| IE | Required | Description |

Remote UE report container | Yes | Carries the report content or event information sent toward the network. |
Remote UE report containerCarries the report content or event information sent toward the network.
Presence: Required
In practice: In practice, compare this field with the original request and with any later release-dependent optional fields so you can see whether the network accepted the same service model the UE asked for.
Likely cause: The branch may depend on Remote UE Report and the report may be missing or malformed.
What to inspect: Check the report container and the later response branch.
Next step: Treat the issue as NAS-side remote reporting before blaming application behavior.
It is the LTE NAS message the UE uses to send remote UE or CIoT report information toward the network.
