Question: When a UE performs idle mode mobility from 5GC to EPC using interworking procedures with N26, how is the 5G <AMF Pointer> mapped to EPS fields?
Option 1: It maps to EPS <MMEGI>
Option 2: It maps to part of EPS <M-TMSI>
Option 3: It maps to EPS <MCC>
Option 4: It maps to part of EPS <MMEC>
Explanation: When a UE performs idle mode mobility from 5GC to EPC using interworking procedures with N26, the 5G <AMF Pointer> is mapped to part of EPS <MMEC>. This mapping allows for the discovery of the source node (i.e., MME or AMF) without ambiguity.
