name: N3A
full_form: Non-3GPP Access
context: When the target UE is connected to the 5G core network via non-3GPP access, the POIs present in the following NFs of the PLMN where the N3A Entity resides provide the LI functions: - AMF. - SMF. - UPF. - SMSF. When the PLMN that has the N3A Entity is the HPLMN, as illustrated in clause A.1, the IRI-POI present in the UDM also provide the LI functions. When the PLMN that has N3A Entity is different from the PLMN that provides the 3GPP access to the target UE, two different AMFs are involved in handling the target UE's registration accepts (this is not illustrated in this clause). In this case, depending on the operator policy, the SMSF present in either of the two networks may perform the routing of SMS messages to and from the target UE. The PLMN that provides the 3GPP access can be a VPLMN and PLMN where the N3A Entity resides can be the HPLMN. In this case, the AMF in the HPLMN provides the IRI-POI functions for non-3GPP access related registration events when the target UE is
description: Non-3GPP Access (N3A) refers to a network that allows user equipment (UE) to connect to the 5G core network using non-3GPP radio access technologies, such as Wi-Fi or fixed networks. This type of access enables UEs to communicate with the 5G core network without using traditional 3GPP cellular networks.
explanation: The context describes N3A as a method for connecting to the 5G core network, utilizing non-cellular technologies. This aligns with the definition of a Network, which encompasses systems facilitating communication between devices.
