Non-3GPP UE attach status indicates whether the non-3GPP UE is now being served by the EPC.
The non-3GPP UE attach status is maintained by the 3GPP AAA Server. In the attached state, the UE can initiate packets and receive services via EPC and non-3GPP access network interworking. Operators need to have the knowledge of the number of attached subscribers in AAA server or AAA proxy server to evaluate the capacity status of servers.
