Problem:
Network initiated explicit deregistration is supported only for CM-CONNECTED.
If requested for CM-IDLE the following ERROR is printed:
"Not implemented : Use Implicit De-registration"

Fix:
Support for CM-IDLE by sending Paging first. When UE enters CM-CONNECTED, UE is explicitly deregistered by sending a Deregistration Request...

ETSI TS 123 502 V16.7.0:

  • 4.2.3.3 Network triggered Service Request, 4b:

If the UE is in RM-REGISTERED state and CM-IDLE and reachable in 3GPP access, the AMF sends a Paging message

  • 4.2.2.3.3 Network-initiated Deregistration, 2:

If the UE is in CM-CONNECTED state, the AMF may explicitly deregister the UE by sending a Deregistration Request message
