5.31.13 Paging for Enhanced Coverage
Taught in 25. Small devices, small messages (The 5G system architecture, in depth).
Support of UEs in E-UTRA Enhanced Coverage is specified in TS 36.300 [30].
Whenever N2 is released and Paging Assistance Data for CE capable UE is available for the UE, the NG-RAN sends it to the AMF as described in clause 4.2.6 of TS 23.502 [3].
The AMF stores the received Paging Assistance Data for CE capable UE and then the AMF includes it in every subsequent Paging message for all NG-RAN nodes selected by the AMF for paging.
If Enhanced Coverage is restricted for the UE as described in clause 5.31.12, the AMF sends the Enhanced Coverage Restriction parameter as defined in TS 38.413 [34].
NOTE: Only the NG-RAN node which cell ID is included in the Paging Assistance Data considers the assistance data.
