2. Description of Related Art

Fifth generation (5G) mobile communication technologies define broad frequency bands such that high transmission rates and new services are possible, and can be implemented not only in “Sub 6 GHz” bands such as 3.5 GHz, but also in “Above 6 GHz” bands referred to as mmWave including 28 GHz and 39 GHz. In addition, it has been considered to implement 6G mobile communication technologies (referred to as beyond 5G systems) in terahertz bands (for example, 95 GHz to 3 THz bands) in order to accomplish transmission rates fifty times faster than 5G mobile communication technologies and ultra-low latencies one-tenth of 5G mobile communication technologies.

At the beginning of the development of 5G mobile communication technologies, in order to support services and to satisfy performance requirements in connection with enhanced mobile broadband (eMBB), ultra reliable low latency communications (URLLC), and massive machine-type communications (mMTC), there has been ongoing standardization regarding beamforming and massive MIMO for mitigating radio-wave path loss and increasing radio-wave transmission distances in mmWave, supporting numerologies (for example, operating multiple subcarrier spacings) for efficiently utilizing mmWave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of bandwidth part (BWP), new channel coding methods such as a low density parity check (LDPC) code for large amount of data transmission and a polar code for highly reliable transmission of control information, L2 pre-processing, and network slicing for providing a dedicated network specialized to a specific service.

Currently, there are ongoing discussions regarding improvement and performance enhancement of initial 5G mobile communication technologies in view of services to be supported by 5G mobile communication technologies, and there has been physical layer standardization regarding technologies such as vehicle-to-everything (V2X) for aiding driving determination by autonomous vehicles based on information regarding positions and states of vehicles transmitted by the vehicles and for enhancing user convenience, new radio unlicensed (NRU) aimed at system operations conforming to various regulation-related requirements in unlicensed bands, NR UE power saving, non-terrestrial network (NTN) which is UE-satellite direct communication for providing coverage in an area in which communication with terrestrial networks is unavailable, and positioning.

Moreover, there has been ongoing standardization in air interface architecture/protocol regarding technologies such as Industrial Internet of Things (IIoT) for supporting new services through interworking and convergence with other industries, integrated access and backhaul (IAB) for providing a node for network service area expansion by supporting a wireless backhaul link and an access link in an integrated manner, mobility enhancement including conditional handover and dual active protocol stack (DAPS) handover, and two-step random access for simplifying random access procedures (2-step RACH for NR). There also has been ongoing standardization in system architecture/service regarding a 5G baseline architecture (for example, service based architecture or service based interface) for combining network functions virtualization (NFV) and software-defined networking (SDN) technologies, and mobile edge computing (MEC) for receiving services based on UE positions.

As 5G mobile communication systems are commercialized, connected devices that have been exponentially increasing will be connected to communication networks, and it is accordingly expected that enhanced functions and performances of 5G mobile communication systems and integrated operations of connected devices will be necessary. To this end, new research is scheduled in connection with extended reality (XR) for efficiently supporting augmented reality (AR), virtual reality VR), mixed reality (MR) and the like, 5G performance improvement and complexity reduction by utilizing artificial intelligence (AI) and machine learning (ML), AI service support, metaverse service support, and drone communication.

Furthermore, such development of 5G mobile communication systems will serve as a basis for developing not only new waveforms for providing coverage in terahertz bands of 6G mobile communication technologies, multi-antenna transmission technologies such as full dimensional MIMO (FD-MIMO), array antennas and large-scale antennas, metamaterial-based lenses and antennas for improving coverage of terahertz band signals, high-dimensional space multiplexing technology using orbital angular momentum (OAM), and reconfigurable intelligent surface (RIS), but also full-duplex technology for increasing frequency efficiency of 6G mobile communication technologies and improving system networks, AI-based communication technology for implementing system optimization by utilizing satellites and AI from the design stage and internalizing end-to-end AI support functions, and next-generation distributed computing technology for implementing services at levels of complexity exceeding the limit of UE operation capability by utilizing ultra-high-performance communication and computing resources.

FIG. 2 illustrates a structure of the 5G network 10 according to embodiments of the present disclosure.

Referring to FIG. 2, the wireless communication system 10 for transmitting, to the UE 100, standalone NPN (SNPN) credentials and subscriber information for accessing an SNPN 20 may include the UE 100, the onboarding SNPN (ON-SNPN) 20, a default credentials server (DCS) 1100, a provisioning server (PVS) 1200, and a subscription owner SNPN (SO-SNPN) 30 possessing SNPN credentials and subscriber information. This figure is a conceptual diagram illustrating control plane-based remote provisioning.

First, it is assumed that the terminal (UE) 100 does not have SNPN credentials and subscriber information (user subscription data), and the UE 100 has default UE credentials allocated by the DCS 1100. In addition, the DCS 1100 may allocate a subscription permanent identifier (SUPI) capable of uniquely identifying the UE 100 to the UE 100.

The ON-SNPN 20 may provide, to the UE 100, UP-based IP connectivity (UE onboarding) or CP-based non-access stratum (NAS) connectivity (UE onboarding) such that the UE 100 without SNPN credentials and subscriber information can receive the SNPN credentials and the subscriber information. The ON-SNPN may request authentication and authorization for the UE 100 from the DCS 1100 in order to determine whether to provide a UE onboarding service to the UE 100. FIG. 2 illustrates UP-based UE onboarding.

The DCS 1100 may pre-configure default UE credentials and an SUPI with respect to the UE 100 and then store the same. The DCS 1100 may receive, from the ON-SNPN, a request for authentication for the UE 100 when performing registration for UE onboarding. The authentication and authorization for the UE 100 is performed based on the default UE credentials and SUPI.

In addition, when the PVS 1200 transmits SNPN credentials and subscriber information to the UE 100, in order to determine whether the UE 100 is a UE having the right to receive the SNPN credentials and the subscriber information, the DCS 1100 may receive a request for UE authentication for the UE 100 from the PVS 1200. The DCS 1100 may be a manufacturer of the UE 100 or a third party associated with the manufacturer or an SNPN network service provider.

The PVS 1200 may receive user subscriber information such as user configuration information and SNPN credentials from the SO-SNPN 30 and transmit the same to the UE.

The PVS 1200 may exist as one server with the DCS 1100, and like the DCS 1100, the PVS 1200 may be a server owned by the manufacturer of the UE 100 or the third party associated with the SNPN network service provider. The PVS 1200 may communicate with the DCS 1100 for the authentication and authorization of the UE 100.

The SO-SNPN 30 possessing the SNPN credentials and the user subscriber information may transmit the SNPN credentials and the user subscriber information to the UE 100 via the PVS 1200.

FIG. 3 illustrates a flowchart of a procedure in which the UE 100 registers with the SNPN 20 in the wireless communication system 10 according to embodiments of the present disclosure.

Referring to FIG. 3, in operation S401, the UE 100 may transmit a registration request message to the (R)AN 200 in order to make onboarding to the ON-SNPN 20. The registration request message may include information indicating that the UE 100 performs CP-based remote provisioning. For example, the registration request message may include a 5GS mobility management (5GMM) core network capability parameter. For example, the 5GMM core network capability parameter may include an information element (IE) called a parameter of a network operation for supporting remote provisioning (parameter in supported network behavior for remote provisioning). For example, the information element may indicate a remote provisioning scheme requested by the UE 100. For example, the information element may indicate control plane-based remote provisioning. The RAN 200 may receive the registration request message from the UE 100.

In operation S402, the RAN 200 may select the AMF 500 supporting onboarding, based on the registration request message received from the UE 100.

In operation S403, the RAN 200 may transmit the registration request message received from the UE 100 to the selected AMF 500. The AMF 500 may receive the registration request message from the RAN 200.

In operation S404, the AMF 500 may determine a remote provisioning scheme for the UE 100, based on the registration request message. For example, the AMF 500 may determine a remote provisioning scheme for the UE 100, based on the 5GMM core network capability parameter included in the registration request message. For example, the AMF 500 may determine the remote provisioning scheme for the UE 100 as a control plane-based (CP-based) remote provisioning, based on the 5GMM core network capability parameter.

In operation S405, the AMF 500 may transmit an identifier request message for requesting an identifier of the UE 100 to the UE 100. For example, the identifier of the UE 100 may be an international mobile equipment identity (IMEI). The UE 100 may receive the identifier request message from the AMF 500.

In operation S406, the UE 100 may transmit an identifier response message including the identifier of the UE 100 to the AMF 500, based on the identifier request message received from the AMF 500. The AMF 500 may receive the identifier response message from the UE 100. Operations S405 and S406 may be selectively performed.

In operation S407, the AMF 500 may select the AUSF 900 which performs authentication for the UE 100. For example, when operations S405 and S406 are performed, the AMF 500 may select the AUSF 900, based on the registration request message and the identifier response message. For example, when operations S405 and S406 are not performed, the AMF 500 may select the AUSF 900, based on the registration request message.

FIG. 4 illustrates a flowchart of an authentication procedure when the UE 100 makes onboarding to the SNPN 20 in a wireless communication system according to embodiments of the present disclosure.
