The present application claims priority to Korean Patent Application No. 10-2023-0107351, filed on Aug. 17, 2023, the entire contents of which is incorporated herein for all purposes by this reference.
The disclosure relates to a method for providing multiple-access to a wireless terminal in a wireless communication network, for example, in a third generation partnership project 5th generation system (3GPP 5GS). Specifically, the present disclosure relates to a method for providing multiple 3GPP accesses to a wireless terminal.
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 mm Wave 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 mm Wave resources and dynamic operation of slot formats, initial access technologies for supporting multi-beam transmission and broadbands, definition and operation of BWP (BandWidth Part), new channel coding methods such as a LDPC (Low Density Parity Check) 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 V2X (Vehicle-to-everything) 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, NR-U (New Radio Unlicensed) 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, IAB (Integrated Access and Backhaul) 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 DAPS (Dual Active Protocol Stack) 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 AR (Augmented Reality), VR (Virtual Reality), MR (Mixed Reality) 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 OAM (Orbital Angular Momentum), and RIS (Reconfigurable Intelligent Surface), 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 (Artificial Intelligence) 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.
Meanwhile, with the development of the above mobile communication system, a need for a method for performing multiple-access-based network selection has arisen.
The present disclosure provides a multiple-access-based network selection method for selecting a network for multiple 3GPP accesses in order for a 5G system to provide multiple 3GPP accesses to a wireless terminal.
According to one embodiment of the disclosure, a multiple-access-based network selection function for selecting a network for multiple 3GPP accesses can be provided in order for a 3GPP 5GS (5G System) to provide multiple 3GPP accesses to a wireless terminal.

Hereinafter, preferred embodiments of the disclosure will be described in detail with reference to the accompanying drawings. In this case, it should be noted that in the accompanying drawings, the same components are denoted by the same reference numerals as much as possible. In addition, detailed descriptions of well-known functions and constitutions that may obscure the gist of the disclosure will be omitted.
In describing the embodiments of the disclosure, descriptions of technical contents that are well known in the technical field to which the disclosure belongs and are not directly related to the disclosure will be omitted. This is to more clearly convey the gist of the disclosure by omitting unnecessary description.
For the same reason, some components are exaggerated, omitted, or schematically illustrated in the accompanying drawings. In addition, the size of each component does not fully reflect the actual size. In each figure, the same or corresponding elements are assigned the same reference numerals.
Advantages and features of one or more embodiments of the disclosure and methods of accomplishing the same may be understood more readily by referring to the following detailed description of the embodiments of the disclosure and the accompanying drawings. The disclosure may, however, be embodied in many different forms and should not be construed as limited to embodiments set forth herein; rather these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure only defined by the claims to one of ordinary skill in the art. The same reference numerals refer to the same elements throughout the disclosure.
In this case, it will be understood that each block of process flowcharts and combinations of the flowcharts may be performed by computer program instructions. Because these computer program instructions may be embedded in a processor of a general-purpose computer, a special-purpose computer, or other programmable data processing apparatuses, the instructions executed through the processor of the computer or other programmable data processing apparatus generates modules for performing the functions described in the flowchart block(s). Because these computer program instructions may also be stored in a computer-executable or computer-readable memory that may direct the computer or other programmable data processing apparatus so as to implement functions in a particular manner, the instructions stored in the computer-executable or computer-readable memory are also capable of producing an article of manufacture containing instruction modules for performing the functions described in the flowchart block(s). Because the computer program instructions may also be embedded into the computer or other programmable data processing apparatus, the instructions for executing the computer or other programmable data processing apparatuses by generating a computer-implemented process by performing a series of operations on the computer or other programmable data processing apparatuses may provide operations for executing the functions described in the flowchart block(s).
Also, each block may represent part of a module, segment, or code that includes one or more executable instructions for executing a specified logical function(s). It should also be noted that, in some alternative implementations, the functions described in the blocks may occur out of the order noted in the drawings. For example, two blocks illustrated in succession may in fact be executed substantially concurrently, or the blocks may sometimes be executed in a reverse order, depending on the functions involved therein.
The term “-unit,” as used in the present embodiment of the disclosure refers to a software or hardware component, such as field-programmable gate array (FPGA) or application-specific integrated circuit (ASIC), which performs certain tasks. However, the term “-unit” is not limited to software or hardware. The term “-unit” may be configured in an addressable storage medium or may be configured to reproduce one or more processors. Therefore, for example, the term “-unit” includes elements, such as software elements, object-oriented software elements, class elements, and task elements, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcodes, circuits, data, databases, data structures, tables, arrays, and variables. Functions provided in the elements and the “-units” may be combined with fewer elements and “-units,” or may be separated from additional elements and “-units” Furthermore, the elements and the “-units” may be implemented to reproduce one or more central processing units (CPUs) in the device or secure multimedia card.
Hereinafter, a base station is an entity that allocates resources to terminals, and may be at least one of a Node B, a base station (BS), an eNode B (eNB), a gNode B (gNB), a wireless access unit, a base station controller, and a node on a network. A terminal may include a user equipment (UE), a mobile station (MS), a 5G UE, a cellular phone, a smartphone, computer, or multimedia systems capable of performing communication functions. Also, embodiments of the disclosure may be applied to other communication systems having a similar technical background or channel type to that of the embodiments of the disclosure. Also, it will be understood by one of ordinary skill in the art that embodiments of the disclosure may be applied to other communication systems through some modifications without departing from the scope of the disclosure. Examples of such communication systems may include 5th generation mobile communication technologies (5G, new radio, and NR) developed beyond LTE-A, and in the following description, the 5G may be the concept that covers the exiting LTE, LTE-A, or other similar services. In addition, based on determinations by those skilled in the art, the embodiments of the disclosure may also be applied to other communication systems through some modifications without significantly departing from the scope of the disclosure.
Hereinafter, an operation principle of the disclosure is described in detail with reference to the accompanying drawings. In describing the disclosure, a detailed description of a related known function or constitution will be omitted if it is deemed to make the gist of the disclosure unnecessarily vague. Furthermore, terms to be described hereunder have been defined by taking into consideration functions in the disclosure, and may be different depending on a user, an operator's intention or practice. Accordingly, each term should be defined based on contents over the entire specification.
Herein, terms to identify access nodes, terms to refer to network entities, terms to refer to messages, terms to refer to interfaces between network entities, terms to refer to various types of identification information, etc., are examples for convenience of explanation. Therefore, the disclosure is not limited to the terms to be described later, and other terms referring to entities having an equivalent technical meaning may be used.
For convenience of description, the disclosure uses terms and names defined in 5GP and NR standards, which are the latest standards among existing communication standards defined by the 3GPP group. However, the disclosure is not limited by the terms and names, and may be equally applied to a wireless communication network following another standard. Particularly, the disclosure may be applied to 3GPP 5GS/NR (e.g., 5th generation mobile communication standard).
In order to increase transfer rate, increase transfer stability, and reduce transfer latency, a wireless communication network, more specifically, 5G system, may provide multiple-access. Conventionally, there was a scheme of using only one 3GPP access and additionally using a non-3GPP access to provide multiple-access to a terminal. However, the coverage of the non-3GPP access may be relatively more restricted than that of the 3GPP access. In addition, there are various types of 3GPP accesses. For example, a 3GPP access may be classified into a public land mobile network (PLMN) and a non-public network (NPN), and can be classified into a sub-6 GHZ band and a higher mmWave band depending on the supported frequency, and may be classified into a terrestrial network (TN) and a non-terrestrial network (NTN). TN and NTN may also be further classified into evolved UMTS terrestrial radio access network (EUTRA), new radio (NR), low Earth orbit (LEO), geostationary orbit (GEO), etc., depending on a radio access technology (RAT). Therefore, a single wireless terminal may use multiple different types of 3GPP accesses simultaneously. For example, 5G system may provide multiple 3GPP accesses to wireless terminals. To support this, a method for selecting a network for multiple 3GPP accesses is required.
In other words, in order for a wireless communication network, more specifically, 5G system to provide multiple 3GPP accesses to wireless terminals, a method for selecting a network for multiple 3GPP accesses is required. Conventionally, only one 3GPP access was used, so network selection was performed for only one 3GPP access. After selecting one network, other networks may be searched, but the searched other networks were not selected, which was a single-access operation.
In this case, in order to increase transfer rate, increase transfer stability, and reduce transfer latency, the wireless communication network, more specifically, 5G system may use only one 3GPP access and additionally use non-3GPP access to provide multiple accesses to the terminal. In this case, as illustrated in (a) of
Meanwhile,
In this case, in order to increase the transfer rate, increase the transfer stability, and reduce the transfer latency, the wireless communication network, more specifically, 3GPP 5GS (5G System), may use one 3GPP access and additionally use another 3GPP access to provide multiple-access to the terminal. In this case, multiple 3GPP accesses may be provided to one terminal through a single CN as illustrated in (a) of
Meanwhile,
The terminal (e.g., UE) may search and select another network after selecting one network (multi-access). In one embodiment, a single CN is used, and the second network may be a network provided by the same CN as the first network.
In this case, the following operations may be performed by considering UE capability, a UE indication, a network indication, UDM subscription, policy, etc.:
According to one embodiment, in a case where the UE selects a network, depending on whether to select SNPN or PLMN, whether only the PLMN ID is identified or the network ID is identified in addition may vary. Accordingly, the UE may determine whether to preferentially select SNPN or PLMN from the network access selection list according to the intent of the Application.
Meanwhile,
The terminal (e.g., UE) may search and select another network after selecting one network (multi-access). In one embodiment, multiple CNs are used, and the second network may be a network provided by another CN that has a service contract with the first network, such as roaming.
In this case, the following operations may be performed by considering UE capability, a UE indication, a network indication, UDM subscription, policy, etc.:
According to one embodiment, in a case where the UE selects a network, depending on whether to select SNPN or PLMN, whether only the PLMN ID is identified or the network ID is identified in addition may vary. Accordingly, the UE may determine whether to preferentially select SNPN or PLMN from the network access selection list according to the intent of the Application.
Meanwhile,
In S501, a terminal (e.g., UE) 500 that has selected a first network may transmit a registration request to an RAN1 510, which is the base station of a corresponding network, in the network selected in operation 1 of S502.

In operation S512, the base station RAN2 520 may select a necessary AMF based on the information received in operation 6. Since the AMF ID corresponds to the same CN, the same AMF of the corresponding CN may be selected. In a case where the same AMF cannot be selected, all the contexts of the existing AMF1 530 may be relocated to a new AMF so that the AMF of operation 7 and the AMF of operation 1 become the same AMF. Then, in operation 7 of S513, the RAN2 520 may transmit the respiration request to the selected AMF1 530. In this case, the registration request may include UE capability, a UE indication, a network indication, a network ID, requested NS IDs, a cell ID, an access type, an AMF ID, etc.

Meanwhile,
In S601, a terminal (e.g., UE) 600 that has selected a first network may transmit a registration request to an RAN1 610, which is the base station of a corresponding network, in the network selected in operation 1 of S602.
