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.

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.

The present disclosure relates to methods and apparatuses. According to some embodiments of the disclosure, a method includes: receiving, at a user equipment, information indicating whether busy indication functionality is supported or not, wherein the busy indication functionality is associated with at least one of Core Network (CN) paging or Radio Access Network (RAN) paging. In addition, a cause value indicating busy indication between Xn interface can be used to determine whether the path switching should be performed or not.

Apparatuses, methods, and systems are disclosed for determining remote unit behavior parameters. One method includes receiving a message including parameters associated with an application in a remote unit. The method includes determining a first set of parameters including a first portion of the parameters, wherein each parameter of the first set of parameters corresponds to a remote unit behavior. The method includes determining a second set of parameters including a second portion of the parameters, wherein each parameter of the second set of parameters corresponds to a service behavior. The method includes associating the second set of parameters with a data network name, a single network slice selection assistance information, or a combination thereof.

Apparatuses, methods, and systems are disclosed for reconfiguring a data connection using new parameters. One apparatus includes a transceiver that communicates with a UE and a processor that registers the UE with a mobile communication network using a first set of parameters, where the first set of parameters is based on a UE configuration. The processor identifies a second set of parameters to be used by the UE in the mobile communication network. Via the transceiver, the processor sends the second set of parameters to the UE and sends mapping information which indicates how the at least one parameter in the second set of parameters corresponds to at least one new parameter for the UE configuration.

Methods and apparatuses for reconfiguring a data connection

For data collection, apparatuses, methods, and systems are disclosed. One apparatus includes a transceiver that receives a first request from a network analytics function to monitor and report occurrences of a first event. The apparatus includes a processor that identifies a first type of network function in a mobile communication network that reports occurrence of the first event. The processor sends a second request to at least one network function of the first type to monitor and report occurrences of the first event and relays reports of occurrence of the first event from the at least one network function to the network analytics function.

Reporting occurrence of an event in a mobile communication network

Apparatuses, methods, and systems are disclosed for NSSAI configuration. One method includes determining a configured network slice selection assistance information for a public land mobile network for a remote unit in response to a trigger from an access and mobility management function. The access and mobility management function, a network slice selection function, or a combination thereof determines the configured network slice selection assistance information. The method includes providing the configured network slice selection assistance information to the remote unit via the access and mobility management function.

Apparatuses, methods, and systems are disclosed for security context handling during AMF reallocation. One apparatus in a mobile communication network includes a network interface and a processor that derives a Reroute Security Context and derives a first authentication parameter for authenticating a Target AMF. The network interface receives a Key Request message from a SEAF co-located with the Target AMF following an AMF reallocation during a UE Registration procedure. The processor verifies the Key Request message by determining whether the second authentication parameter matches the first authentication parameter derived for authenticating the Target AMF. The processor derives a new security context for the Target AMF/SEAF in response to successfully verifying the Key Request message. The network interface sends a Key Response message to the Target AMF/SEAF.

Apparatuses, methods, and systems are disclosed for supporting edge data network discovery. One apparatus receives a first request from a function in a mobile communication network, the first request including a UE ID and a UE network address. The apparatus may determine whether the UE is located in a first service area based at least in part on a UE location and forward a DNS request to a first DNS server associated with the first service area based at least in part on a determination that the UE is located in the first service area. The apparatus may further receive a DNS reply and transmit a second request to a policy function in the mobile communication network based at least in part on a determination that the DNS reply includes a first IP address.
