name: N1:
full_form: Reference point between the UE and the AMF.
context: The IRI-POI in the AMF shall generate an xIRI containing an AMFDeregistration record when the IRI-POI present in the AMF detects that a UE matching one of the target identifiers provided via LI_X1 has deregistered from the 5GS over at least one access type. Accordingly, the IRI-POI in AMF generates the xIRI when any of the following events is detected: - For network initiated de-registration, when the AMF receives the N1: DEREGISTRATION ACCEPT message from the target UE or when implicit deregistration timer expires; and in both cases the UE 5GMN state for the access type (3GPP NG-RAN or non-3GPP access) within the AMF is changed to 5GMM-DEREGISTERED. - For UE initiated de-registration, when the AMF sends the N1: DEREGISTRATION ACCEPT message to the target UE or when the AMF receives the N1: DEREGISTRATION REQUEST message from the target UE with deregistration type value of âswitch offâ; and in both cases the UE 5GMN state for the access type (3GPP NG-RAN or non-3GPP access) within the
description: The N1 interface is a reference point between the User Equipment (UE) and the Access and Mobility Management Function (AMF) in the 5G core network. It enables communication for session management, connection establishment, and deregistration procedures.
explanation: N1 is classified as an Interface because it defines a communication pathway between the UE and the AMF, facilitating the exchange of control messages essential for user mobility and network access.
