Description

Prerequisites

What problem does this feature solve or what does it enhance?

User jamyla posted on the community mattermost about an IMSI catcher that uses LPP to track UE location. Reporting LPP messages has been previously suggested in #534, but as far as I know nobody's tried it out. This seems like an interesting heuristic to add, even if only in an informational (as opposed to a warning) capacity.

Proposed Solution

Implement an informational heuristic that tracks LTE LPP messages, both the request and the response.

Alternatives Considered

No response

Contributor guide

Research direction
Study the LPP message format and implement an informational heuristic in the Rust decoder to track both LPP requests and responses.
