A method according to an embodiment of the present application may include: receiving a registration request for a user equipment (UE), wherein the register request indicates an identity of the UE, an onboarding and provisioning flag, and an onboarding and provisioning function (OPF) identity; selecting an OPF entity at least based on the OPF identity in the case of an onboarding request being supported for the UE; and transmitting the onboarding request at least indicating the identity of the UE to the selected OPF entity.

Method and apparatus for providing onboarding and provisioning services

Apparatuses, methods, and systems are disclosed for determining and enforcing service specific network slice security. One apparatus in a mobile communication network includes processor that performs primary authentication with a mobile communication network and a transceiver that receives a SMC message comprising SSI. The processor applies slice security for control plane and user plane traffic related to a network slice according to a Security Requirement Type indicated in the SSI.

Apparatuses, methods, and systems are disclosed for Digital Identifier-based subscription onboarding. One apparatus includes a memory coupled to a processor, the memory storing instructions executable by the processor to control the apparatus to acquire a Digital Identifier ('DIG-ID') comprising a verifiably secure identity, and to generate a digital signature of the DIG-ID and a timestamp using a private key. The instructions are executable by the processor to control the apparatus to send a first request to a mobile communication network and to receive a response containing an onboarding authentication success indication and a verified DIG-ID, the first request including the DIG-ID, the timestamp and the digital signature. The instructions are executable by the processor to establish a provisioning connection to the mobile communication network and to receive a subscription credential and/or a user subscription profile via the provisioning connection.

Apparatuses, methods, and systems are disclosed for relocating an access gateway during UE registration. One apparatus includes an interface that communicates with a remote unit and with a plurality of network functions in a mobile communication network. The apparatus includes a processor that initiates registration of the remote unit with the mobile communication network and receives a relocation command from an AMF while the registration is ongoing, the relocation command containing an address of a first TNGF and a first security key. If connectivity with the first TNGF is supported, then the processor sends a first request to the first TNGF, the first request containing a remote unit identity and an AMF identity. However, if connectivity with the first TNGF is not supported, then the processor sends a relocation reject message to the AMF.

Relocating an access gateway

Apparatuses, methods, and systems are disclosed for establishing a data connection for UAV operation. One apparatus includes a processor and a transceiver that communicates with a mobile communication network via an access network. Here, the processor sends (e.g., via the transceiver) a data connection request to a session management function, the data connection request requesting unmanned aerial vehicle ('UAV') operation. The processor receives (e.g., via the transceiver) a response to the data connection request. Here, the response includes remote identification and tracking information (“RITI”) for the UAV operation. The processor further sends (e.g., via the transceiver) one or more UAV data reports to a UAV Traffic Management (“UTM”) function using the RITI.

Requesting data connection for UAV operation

Apparatuses, methods, and systems are disclosed for indicating a network for a remote unit. One method includes transmitting a first message including a first registration request from a remote unit. The first message includes a discovery indication indicating that the remote unit is attempting to discover a network configured for use by the remote unit. The method includes receiving a second message including a list of networks configured for use by the remote unit. The second message is received in response to transmitting the first message. The method includes transmitting a third message including a second registration request from the remote unit. The second registration request includes an indication of a network selected from the list of networks configured for use by the remote unit.

Indicating a network for a remote unit

Method and apparatus for application server change are disclosed. A method includes obtaining information on application server change for an application when server changes to a target application server and making a decision to inform a user equipment ('UE') to rediscover the target application server for the application or configure UPF to steer traffic to and from the target application server for the application.

Server discovery improvement when application server changes

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.

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.
