1. An apparatus comprising:
a transceiver; and
a processor coupled to the transceiver, the processor configured to cause the apparatus to:
receive, from a remote unit via a non-Third Generation Partnership Project (“non-3GPP”) access network, a first authentication request comprising network slice selection information, the first authentication request corresponding to a first authentication procedure;
select a network slice in a mobile core network based on the network slice selection information;
forward the first authentication request to the mobile core network to initiate connection of the remote unit to the mobile core network;
receive a second authentication request from the mobile core network, wherein the second authentication request is part of a Non-Access Stratum (“NAS”) authentication procedure different than the first authentication procedure;
transform the second authentication request into a third authentication request of the first authentication procedure; and
complete connection of the remote unit to the mobile core network using an authentication response of the first authentication procedure.
