Access network selection for a UE not supporting NAS over non-3GPP access

Abstract

Apparatuses, methods, and systems are disclosed for access network selection for UEs not supporting NAS over non-3GPP access. One apparatus includes a processor and a transceiver for communicating with one or more non-3GPP access networks. The processor creates a first list of available PLMNs, each PLMN connectable via a non-3GPP access network without using a NAS protocol. The processor selects a first PLMN from the first list and selects a first network slice supported by the first PLMN. Here, the first network slice is identified by a first S-NSSAI. The processor creates a second list of available non-3GPP access networks and selects a first non-3GPP access network from the second list. The processor begins a connectivity procedure over the first non-3GPP access network. Here, the connectivity procedure creates a data connection for the apparatus via the first network slice in the first PLMN, and the connectivity procedure does not use the NAS protocol.

Dependencies are inferred from the claim text.
