Apparatuses, methods, and systems are disclosed for using a pseudonym for access authentication over non-3GPP access. One apparatus includes a processor and a transceiver that communicates with a mobile communication network using a 3GPP access network and a non-3GPP access network. The processor sends a registration message to a first network function in the mobile communication network via the 3GPP access network, the first authentication message comprising a first indicator and a SUCI for the apparatus, wherein the first indicator comprises an indication that the apparatus has the capability for access authentication for non-3GPP access in an EPS. The processor receives a first identity pseudonym for the apparatus in response to the registration message comprising the first indicator and performs access authentication via a non-3GPP access network using the first identify pseudonym.

Using a pseudonym for access authentication over non-3GPP access

Apparatuses, methods, and systems are disclosed for access network selection for UEs not supporting the Non-Access Stratum ('NAS') protocol over non-3GPP access. One method includes creating a first list of available PLMNs, each PLMN connectable via a non-3GPP access network using a 5G connectivity without the NAS protocol. The method includes selecting a first PLMN from the first list and creating a second list of available non-3GPP access networks. The method includes selecting a first non-3GPP access network from the second list and beginning a connectivity procedure over the first non-3GPP access network, where the connectivity procedure creates a data connection for the apparatus via the first PLMN, and where the connectivity procedure does not use the NAS protocol.

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

Apparatuses, methods, and systems are disclosed for measuring Round Trip Time ('RTT'). One apparatus includes a processor and a transceiver that communicates via an access network. The processor establishes a data connection capable of communicating PDUs over the access network and establishes a measurement session via the data connection. The processor stores a first set of parameters for each PDU sent over the data connection and receives a first message via the measurement session. The processor calculates a value based on the first message and the first set of parameters.
