Patent ID: 11638208

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.
