name: MM-NULL
full_form: Mobility Management Null State
context: When the DETACH REQUEST message is received by the network, a DETACH ACCEPT message shall be sent to the UE, if the Detach type IE does not indicate "switch off". Otherwise, the procedure is completed when the network receives the DETACH REQUEST message.
  Depending on the value of the Detach type IE the following applies:
  -	combined EPS/IMSI detach:
  The network and the UE shall deactivate the EPS bearer context(s) for this UE locally without peer-to-peer signalling between the UE and the MME. The UE is marked as inactive in the network for EPS and for non-EPS services. The states EMM-DEREGISTERED and MM-NULL are entered in both the UE and the network.
  -	IMSI detach:
  The UE is marked as inactive in the network for non-EPS services. The states MM-NULL and EMM-REGISTERED are entered in both the UE and the network.
  The UE, when receiving the DETACH ACCEPT message, shall stop timer T3421.
description: The MM-NULL state is entered by both the UE and the network when an IMSI detach or combined EPS/IMSI detach procedure is completed, indicating that the UE has no active mobility management context.
explanation: Categorized as a State since it describes the status of the UE's mobility management in the network.
