Systems, apparatuses, methods, and one or more computer-readable media storing executable instructions for registering a multi-port device are described. A computing device may receive a registration request from a user device supporting multiple ports. In response, the computing device may send to the user device a message including a plurality of telephone numbers and information of associated ports.

In one embodiment of the present invention, a method for enabling a UDM (Unified Data Management) to perform a registration related procedure of an AMF (Access and Mobility Management Function) in a wireless communication system comprises the steps of: receiving, by the UDM, a message related to serving AMF registration of a UE, which includes access type information and ID (Identity) information, from a first AMF; transmitting, by the UDM, a deregistration related message to a second AMF when the second AMF exists, wherein the second AMF is registered as a serving AMF of the UE and related to the access type information.

A wireless device sends a registration request message to an access and mobility management function (AMF) of a network. The wireless device receives, from the AMF, a registration accept message comprising an access traffic steering, switching, and splitting (ATSSS) capability indication of the network.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE).

Embodiments herein disclose a method performed by a terminal in a mobile communication system. The method includes performing a registration procedure on a first standalone non-public network (SNPN), selecting a second SNPN based on a predetermined condition, and transmitting, to a network entity, a registration request message on the second SNPN for an initial registration, in case that the second SNPN differs from the first SNPN.

Systems and methods are provided for managing updates to user devices, and in particular, SIM-based OTA updates. In some cases, SIMOTA updates need to be made while a user device has a cellular connection (e.g., 4G/LTE, 5G). As such, an instruction is transmitted to the user devices that need a SIM-based update but that currently have a non-cellular connection. The instruction is for the user devices to deregister from the non-cellular connection and to reregister using a cellular connection. An indication is received that at least a portion of those user devices now currently have a cellular connection. The SIM-based updates are then transmitted to those user devices.

Devices, methods, use user equipment (UE), core network devices, evolved node B (eNB), and storage media for UE provisioning are described. In one embodiment, processing circuitry of a mobility management entity (MME) decodes a non-access stratum (NAS) message comprising a detach request associated with a first user equipment (UE) and determines that the detach request is received from the UE without integrity protection. The MME then analyzes one or more additional criteria associated with the detach request in response to confirmation that the detach request message is received from the UE without the integrity protection, and manages an evolved packet system (EPS) mobility management (EMM) registration state for the first UE based on analysis of the one or more additional criteria. Various different criteria and associated EMM registration state management operations are described. Additional corresponding UE operations are also described.
