Acquiring a first confirmation result relating to whether or not access to the network restricted by the restriction information is possible; and a transmission unit that transmits, to the base station, a wireless connection setting request including the first cause value when the first confirmation result is that access is possible.

Description

Technical Field

[0001] This invention relates to terminals, base stations, and communication methods in communication systems. Background Technology

[0002] Within the 3GPP (3rd Generation Partnership Project), research was conducted on a wireless communication method known as 5G or NR (New Radio) to further increase system capacity, accelerate data transmission speeds, and reduce latency in the radio space. Within 5G, various wireless technologies were researched to meet the requirement of achieving throughput exceeding 10Gbps while maintaining latency below 1ms in the radio space.

[0003] In NR, a network architecture including 5GC (5G Core Network) and NG-RAN (Next Generation-Radio Access Network) is being studied. The 5GC corresponds to the core network EPC (Evolved Packet Core) in the LTE (Long Term Evolution) network architecture, and the NG-RAN corresponds to the RAN (Radio Access Network) E-UTRAN (Evolved Universal Terrestrial Radio Access Network) in the LTE network architecture (e.g., Non-Patent Document 1).

[0004] In addition, research has begun on future systems or 6G in comparison to 5G. In these future systems, diverse requirements related to power consumption, latency, and communication speed are envisioned for various terminals such as Ambient IoT (such as wireless tags) and XR (X-ray) devices with enhanced virtual reality capabilities.

[0011] The problem that the invention aims to solve

[0012] Before a terminal begins using a network based on an operating profile under a formal contract with a mobile operator, it accesses the network using a configuration profile for pre-configuration. In situations where network access restrictions are implemented during disasters or other events, terminals accessing using the configuration profile should have a lower access pass-through rate compared to terminals accessing using the operating profile.

[0013] However, existing network specifications do not distinguish between terminals accessing the network using configuration profiles and terminals accessing the network using runtime profiles in the access restrictions.

[0014] The present invention was made in view of the above-mentioned problems, and its object is to implement access restrictions for terminals that access using configuration profiles in a communication system, in a manner that is distinct from those for terminals that access using a configuration profile.

[0015] Methods for solving problems

[0016] According to the disclosed technology, a terminal is provided, comprising: a receiving unit that receives from a base station restriction information restricting access by a terminal using a configuration profile; a control unit that, when performing access using a configuration profile, derives a first access identifier corresponding to the access using the configuration profile and a first cause value corresponding to the first access identifier, and obtains a first confirmation result related to whether access to the network restricted by the restriction information is possible based on the first access identifier; and a sending unit that, if the first confirmation result indicates that access is possible, sends a wireless connection setting request including the first cause value to the base station.

[0017] Invention Effects

[0018] According to the disclosed technology, in a communication system, access restrictions can be implemented separately for terminals that access using a configuration profile, distinct from those for terminals that access using a configuration profile. Attached Figure Description

[0026] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Furthermore, the embodiments described below are examples, and the application of the present invention is not limited to the embodiments described below.

[0027] In the operation of the wireless communication system according to embodiments of the present invention, existing technologies are appropriately used. These existing technologies include, for example, existing LTE, but are not limited to, existing LTE. Furthermore, unless otherwise stated, the term "LTE" as used herein has a broad meaning that includes LTE-Advanced and later versions (e.g., NR), or wireless LAN (Local Area Network).

[0028] In addition, in embodiments of the present invention, the “configure” wireless parameters can be pre-configured predetermined values, or wireless parameters notified from network node 30 or terminal 20.

[0029] Figure 1 This is a diagram used to illustrate an example of a communication system. For example... Figure 1As shown, the communication system consists of a UE (User Equipment) as terminal 20 and multiple network nodes 30. Hereinafter, each function is assumed to correspond to one network node 30, but multiple functions can be implemented by one network node 30, or one function can be implemented by multiple network nodes 30. Furthermore, the term "connection" as used below can refer to either a logical connection or a physical connection.

[0030] The RAN (Radio Access Network) is a network node 30 with radio access capabilities, and may also include a base station 10. It connects to the UE, AMF (Access and Mobility Management Function), and UPF (User Plane Function). The AMF is a network node 30 with functions such as RAN interface termination, NAS (Non-Access Stratum) termination, registration management, connection management, reachability management, and mobility management. The UPF is a network node 30 interconnected with the DN (Data Network) and has functions such as external PDU (Protocol Data Unit) session points, packet routing and forwarding, and user plane QoS (Quality of Service) processing. The UPF and DN constitute a network slice. In the wireless communication network of this embodiment, multiple network slices are constructed.

[0031] The AMF connects with the UE, RAN, SMF (Session Management function), NSSF (Network Slice Selection Function), NEF (Network Exposure Function), NRF (Network Repository Function), UDM (Unified Data Management), ASF (Authentication Server Function), PCF (Policy Control Function), and AF (Application Function). AMF, SMF, NSSF, NEF, NRF, UDM, ASF, PCF, and AF are interconnected network nodes 30 via interfaces based on their respective services: Namf, Nsmf, Nnsf, Nnef, Nnrf, Nudm, Nausf, Npcf, and Naf.

[0032] The SMF (Service Provider Function) is a network node 30 with functions such as session management, UE IP (Internet Protocol) address allocation and management, DHCP (Dynamic Host Configuration Protocol) functionality, ARP (Address Resolution Protocol) proxy, and roaming capabilities. The NEF (Network Function Provider Function) is a network node 30 with the ability to notify other NFs (Network Functions) of events. The NSSF (Network Slice Selection Assistance Information) is a network node 30 with functions such as selecting the network slice to which the UE connects, determining the authorized NSSAI (Network Slice Selection Assistance Information), determining the configured NSSAI, and determining the AMF set to which the UE connects. The PCF (Public Configuration Function Provider Function) is a network node 30 with the function of performing network policy control. The AF (Application Provider Function) is a network node 30 with the function of controlling application servers. The NRF (Network Provider Function) is a network node 30 with the function of discovering NF instances that provide services. The UDM (User Data Repository) is a network node 30 that manages subscriber data and authentication data. The UDM is connected to the UDR (User Data Repository) that maintains this data. Alternatively, a UDM can also have: ARPF (Authentication Credential Repository and Processing Function), which performs the processing and management of authentication information; and SIDF (Subscription Identifier De-concealing Function), which decodes encrypted identification information. Alternatively, a UDM can also perform these functions by connecting to other network nodes that have ARPF or SIDF.

[0033] Figure 2 This is a diagram illustrating an example of a communication system in a roaming environment. For example... Figure 2 As shown, the network consists of a UE (User Equipment) as terminal 20 and multiple network nodes 30. Hereinafter, each function is assumed to correspond to one network node 30, but multiple functions can be implemented by one network node 30, or one function can be implemented by multiple network nodes 30. Furthermore, the term "connection" as used below can refer to either a logical connection or a physical connection.

[0034] The RAN is a network node 30 with wireless access capabilities, connected to the UE, AMF, and UPF. The AMF is a network node 30 with functions such as RAN interface termination, NAS termination, registration management, connection management, reachability management, and mobility management. The UPF is a network node 30 interconnected with the DN, with functions such as external PDU session points, packet routing and forwarding, and user plane QoS processing. The UPF and DN constitute a network slice. In the wireless communication network of this embodiment, multiple network slices are constructed.

[0035] AMF connects to UE, RAN, SMF, NSSF, NEF, NRF, UDM, AUSF, PCF, AF, and SEPP (Security Edge Protection Proxy). AMF, SMF, NSSF, NEF, NRF, UDM, AUSF, PCF, and AF are network nodes 30 interconnected via interfaces based on their respective services: Namf, Nsmf, Nnsf, Nnef, Nnrf, Nudm, Nausf, Npcf, and Naf.

[0036] The SMF (Service Provider Function) is a network node 30 with functions such as session management, UE IP address allocation and management, DHCP, ARP proxy, and roaming. The NEF (Network Element Function) is a network node 30 with the ability to notify other NFs and handle events. The NSSF (Network Node SF) is a network node 30 with functions such as selecting the network slice to which the UE connects, determining the authorized NSSAI (Network Service Identity), determining the configured NSSAI, and determining the AMF set to which the UE connects. The PCF (Network Node SF) is a network node 30 with the function of performing network policy control. The AF (Application Provider Function) is a network node 30 with the function of controlling application servers. The NRF (Network Node RF) is a network node 30 with the function of discovering NF instances that provide services. The SEPP (Secure Provider Proxy) is a non-transparent proxy used to filter control plane messages between PLMNs (Public Land Mobile Networks). Figure 2 The vSEPP shown is the SEPP in the visited network, and the hSEPP is the SEPP in the home network.

[0037] like Figure 2 As shown, the UE is in a roaming environment within a VPLMN (Visited PLMN) connected to the RAN and AMF. The VPLMN and HPLMN (Home PLMN) are connected via vSEPP and hSEPP, respectively. The UE can, for example, communicate with the UDM of the HPLMN via the AMF of the VPLMN.

[0038] (Example 1)

[0039] Example 1 will be described. In Example 1, a process for executing access restrictions for terminals accessing using a configuration profile in a communication system, distinguishing them from terminals accessing using a configuration profile, will be described. Figure 3 This is a diagram illustrating an example of a timing diagram in an embodiment of the present invention. Figure 3 In the timing diagram shown, terminal 20 communicates with the upper-level application (referred to as the upper-level application), 5GMM (5GS mobility management), eUICC (embedded Universal Integrated Circuit Card), and AS (Access Stratum) within terminal 20. 5GMM is a protocol in NAS (Non-Access Stratum, see Non-Patent Document 2), and also means the entity within the terminal that processes this protocol, communicating with the eUICC and AS within terminal 20 in the latter sense. The AS within terminal 20 communicates with base station 10. The eUICC has a Provisional Profile (PP) and an Operational Profile (OP). The Provisional Profile (PP) is used for pre-configuration before starting network use based on the Operational Profile (OP). The Operational Profile (OP) is used to utilize the mobile operator's services based on a formal contract with the mobile operator. The following will describe... Figure 3 The processing of each step in the timing diagram is explained.

[0040] Step S301: The AMF sends an Overload Start message to the base station 10 as a message indicating that the AMF is under high load (see sections 8.7.7.2 and 9.2.6.14 of Non-Patent Document 3, etc.). Here, Overload Start includes an Overload Response requesting a specified action (see section 9.3.1.104 of Non-Patent Document 3). Overload Response includes an Overload Action requesting an action (see section 9.3.1.105 of Non-Patent Document 3). Here, Overload Action includes a newly defined setting value (e.g., expressed as "Permit OP only") indicating that access is only authorized for terminals 20 using the operating profile. That is, this setting value indicates that access is not restricted for terminals 20 using the operating profile, but access restrictions are enforced for terminals 20 using setting profiles other than the operating profile. Additionally, Overload Start includes Traffic Load Reduction Indication (see section 9.3.1.106 of Non-Patent Document 3), which specifies the proportion of terminals 20 that are not authorized to access as a reduction ratio for access restrictions. For example, if the value of Traffic Load Reduction Indication is 80, it means that the proportion of terminals 20 that are not authorized to access is 80%.

[0041] Step S302: Based on the message received in step S301, base station 10 sends restriction information restricting outgoing calls based on terminal 20 to the AS of terminal 20. The restriction information is sent as a message SIB1 in the RRC protocol (see section 6.2.2 of Non-Patent Document 4). Here, a new number (e.g., 4) representing access based on the terminal 20 using the configuration profile is defined as the access identity number (see section 4.5.2 of Non-Patent Document 2, etc.). Furthermore, a new setting information is defined to set the proportion of terminals 20 authorized to access corresponding to this new number (e.g., expressed as "uac-BarringFactorForAI4"). Based on the proportion of terminals 20 not authorized to access specified in the message received in step S301 relative to terminals 20 accessing using the operation profile (OP) (e.g., 80%), base station 10 sets the authorized access proportion (e.g., 20%) relative to terminals 20 accessing using the configuration profile (PP).

[0042] Step S303: The host application of terminal 20 sends an access request to the network using the configuration profile (PP) to the 5GMM of terminal 20.

[0043] Step S304: The 5GMM of terminal 20 sends a request to read the configuration profile (PP) to the eUICC of terminal 20.

[0044] Step S305: The eUICC of terminal 20 reads the configuration profile (PP) according to the request received in step S304, and sends a response to the request to the 5GMM of terminal 20.

[0045] Step S306: Terminal 20 exports the 5GMM and the access identifier corresponding to the access based on the configuration profile (PP). Here, the exported number is a new number (e.g., 4) that represents the access of terminal 20 based on the configuration profile (PP) as explained in step S302.

[0046] Step S307: Terminal 20 derives a cause value (RRC Establishment Cause, see Section 4.5.6 of Non-Patent Document 2) corresponding to the access identifier value derived in step S306. Here, the derived cause value is a newly defined cause value corresponding to the access identifier derived in step S306, indicating that terminal 20 is accessing using a setup profile (PP) (e.g., expressed as "pp in use").

[0047] Step S308: The 5GMM of terminal 20 notifies the AS of terminal 20 of the access identifier exported in step S306 and the reason value exported in step S307.

[0048] Step S309: The AS of terminal 20 determines whether it can access the network based on the restriction information received in step S308 and the access identifier received in step S306. For example, if the proportion of terminals 20 authorized to access based on the access identifier restricted by the restriction information is X% (i.e., the number of accessing terminals 20 is limited to less than X%), the AS in terminal 20 generates a random number greater than or equal to 0 and less than 1. If the value of the generated random number is less than X / 100 (e.g., less than 0.1 when X is 10%), it is determined that access is possible; otherwise, it is determined that access is not possible (see section 5.3.14.5 of Non-Patent Document 4).

[0049] If the result confirms that access is possible, steps S310 to S313 are executed; if the result confirms that access is not possible, steps S314 to S316 are executed.

[0050] (The result confirms that access is possible)

[0051] Step S310: The AS of terminal 20 sends the confirmation result (access successful) determined in step S309 to the 5GMM of terminal 20.

[0052] Step S311: Based on the confirmation result (access successful) received in step S310, the 5GMM of terminal 20 continues the processing related to network access using the configuration profile (PP).

[0053] Step S312: The 5GMM of terminal 20 requests access to the network using the configuration profile (PP) from the AS of terminal 20.

[0054] Step S313: The AS of terminal 20 sends an RRC Setup Request to base station 10 (see section 6.2.2 of Non-Patent Document 4). This message sets the cause value received in step S308 (RRCEstablishment Cause = "pp in use"). This message can also be referred to as a wireless connection setup request.

[0055] (The result confirms that the connection cannot be established)

[0056] Step S314: The AS of terminal 20 sends the confirmation result (access denied) determined in step S309 to the 5GMM of terminal 20.

[0057] Step S315: Based on the confirmation result (access denied) received in step S314, the 5GMM of terminal 20 terminates the processing related to access to the network using the configuration profile (PP).

[0058] Step S316: The 5GMM of terminal 20 notifies the upper layer application of terminal 20 that access to the network using the configuration profile (PP) is not allowed.

[0059] According to the above embodiments, in a communication system, access restrictions can be implemented separately for terminals that access using a specified configuration profile, distinct from those for terminals that access using a configuration profile.

[0060] (Example 1)

[0061] use Figure 3 The timing diagram illustrates the first variation of Example 1.

[0062] Step S301: Similar to the description of Embodiment 1 above, the AMF sends an Overload Start message to the base station 10 as a message indicating that the AMF is under high load.

[0063] Step S302: Based on the message received in step S301, base station 10 begins to implement access restrictions for terminal 20 in its own device. That is, base station 10 does not send restriction information restricting access based on terminal 20 to the AS of terminal 20, but performs access restrictions in its own device.

[0064] Next, similarly to the description of Embodiment 1 above, steps S303 to S308 are executed on the terminal 20 side. Here, since the AS of terminal 20 did not receive the restriction information from base station 10, terminal 20 determines that it can access the network, and therefore steps S309 to S312 and steps S314 to S316 are not executed. That is, next, terminal 20 executes step S313.

[0065] Base station 10 confirms whether terminal 20 can access the network based on the Overload Start received in step S301 and the RRC SetupRequest received from the AS of terminal 20. Specifically, base station 10 confirms whether terminal 20 accessing the network using the setup profile (PP) can access the network based on the setting value "Permit OP only" in the Overload Action included in the Overload Start, the Traffic Load Reduction Indication value specifying the proportion of terminals 20 not authorized to access, and the cause value set in the RRC SetupRequest indicating that terminals 20 accessing using the setup profile (PP) are using the setup profile (PP) (RRC Establishment Cause = "pp in use"). Base station 10 can also calculate the proportion of authorized terminals 20 (e.g., 20%) based on the proportion of unauthorized terminals 20 (e.g., 80%). The confirmation method is the same as the method performed by terminal 20 in step S309 described in Embodiment 1 above.

[0066] If the result confirms that access is possible, base station 10 continues to perform the processing for terminal 20 to connect to the network.

[0067] If the confirmation result indicates that access is not possible, base station 10 will interrupt the process. Furthermore, base station 10 may also send a notification to terminal 20 that it will not accept the RRC SetupRequest message received from terminal 20.

[0068] According to the above embodiments, in a communication system, access restrictions can be implemented separately for terminals that access using a specified configuration profile, distinct from those for terminals that access using a configuration profile.

[0069] (Second variation)

[0070] A second variation of Embodiment 1 will be described. In this second variation, the terminal 20 has two types of setting profiles (PPs): one for priority use (e.g., for use in police, fire, etc.) and one for general use. Here, when using the general-use setting profile (PP), the same processing as in the first embodiment described above is performed. Hereinafter, using... Figure 3 The timing diagram illustrates the use of the priority setting profile (PP).

[0071] Steps S301 and S302 are performed in the same manner as in Embodiment 1 described above.

[0072] Step S303: The host application of terminal 20 sends an access request to the network using a priority configuration profile (PP) to the 5GMM of terminal 20.

[0073] Step S304: The 5GMM of terminal 20 sends a read request for the priority configuration profile (PP) to the eUICC of terminal 20.

[0074] Step S305: The eUICC of terminal 20 reads the priority configuration profile (PP) according to the request received in step S304, and sends a response to the request to the 5GMM of terminal 20.

[0075] Step S306: Terminal 20 exports the 5GMM and the access identifier corresponding to the access based on the priority setting profile (PP). Here, the exported number is the access number indicating priority (1, see section 4.5.2 of Non-Patent Document 2).

[0076] Step S307: Terminal 20 outputs the cause value corresponding to the value of the access identifier exported in step S306 (RRC Establishment Cause="mps-PriorityAccess, see section 4.5.6 of Non-Patent Document 2).

[0077] Step S308: The 5GMM of terminal 20 notifies the AS of terminal 20 of the access identifier derived in step S306 and the reason value derived in step S307. Here, when accessing the network using the preferred configuration profile (PP), terminal 20 does not respond to the restriction information received in step S302. That is, terminal 20 determines that it can access the network, and does not execute the processes of steps S309 to S312 and steps S314 to S316, but executes the process of step S313 as shown below.

[0078] Step S313: The AS of terminal 20 sends an RRC Setup Request to base station 10. This message sets the cause value received in step S308 (RRC Establishment Cause = "mps-PriorityAccess"). This message can also be called a wireless connection setup request.

[0079] Through the above processing, in the second variation, the terminal accessing the network using the general configuration profile is subject to access restrictions separately from the terminal accessing the network using the operation profile. On the other hand, the terminal accessing the network using the priority configuration profile can operate as the priority terminal without being subject to restrictions separately from the terminal accessing the network using the operation profile.

[0080] According to the above embodiments, in a communication system, access restrictions can be implemented separately for terminals that access using a specified configuration profile, distinct from those for terminals that access using a configuration profile.

[0081] (Device structure)

[0082] Next, an example of the functional structure of the base station 10, network node 30, and terminal 20 implementing the processes and actions described above will be explained. The base station 10, network node 30, and terminal 20 include the functions implemented in the above embodiments. However, the base station 10, network node 30, and terminal 20 may each possess only a portion of the functions described in the embodiments.

[0083] <Base station 10 and network node 30>

[0084] Figure 4 This is a diagram illustrating an example of the functional structure of base station 10 and network node 30. (See diagram for example.) Figure 4 As shown, the base station 10 includes a transmitting unit 110, a receiving unit 120, a setting unit 130, and a control unit 140. Figure 4 The functional structure shown is only one example. The functional distinctions and names of the functional units can be arbitrary, as long as the actions involved in the embodiments of the present invention can be implemented. Furthermore, the network node 30 may also have the same functional structure as the base station 10. Additionally, the system architecture may consist of multiple network nodes 30 with different functions, or multiple network nodes 30 separated by function.

[0085] The transmitting unit 110 includes the function of generating a signal to be transmitted to the terminal 20 or other network node 30 and transmitting the signal in a wired or wireless manner. The receiving unit 120 includes the function of receiving various signals transmitted from the terminal 20 or other network node 30 and obtaining, for example, higher-level information from the received signals. A communication unit including the transmitting unit 110 and the receiving unit 120 may also be configured.

[0086] The setting unit 130 stores the preset setting information and various setting information sent to the terminal 20 in the storage device, and reads them from the storage device as needed.

[0087] As described in the embodiment, the control unit 140 performs processing related to access restrictions of the terminal 20. Additionally, the control unit 140 performs processing related to communication with the terminal 20. Alternatively, the signal transmission-related functional units of the control unit 140 may be included in the transmitting unit 110, and the signal reception-related functional units of the control unit 140 may be included in the receiving unit 120.

[0088] Terminal 20

[0089] Figure 5 This is a diagram illustrating an example of the functional structure of terminal 20. (As shown...) Figure 5 As shown, the terminal 20 includes a transmitting unit 210, a receiving unit 220, a setting unit 230, and a control unit 240. Figure 5 The functional structure shown is only one example. The functional distinctions and names of the functional units can be arbitrary, as long as the actions involved in the embodiments of the present invention can be implemented. Furthermore, the communication device that becomes the resource holder 20 may also have the same functional structure as the terminal 20.

[0090] The transmitting unit 210 generates a transmission signal based on the transmission data and transmits the signal wirelessly. The receiving unit 220 wirelessly receives various signals and extracts higher-layer signals from the received physical layer signals. Additionally, the receiving unit 220 has the function of receiving control signals or reference signals transmitted from the network node 30. A communication unit comprising the transmitting unit 210 and the receiving unit 220 may also be configured.

[0091] The setting unit 230 stores various setting information received by the receiving unit 220 from the network node 30 in a storage device, and reads it from the storage device as needed. In addition, the setting unit 230 also stores preset setting information.

[0092] As described in the embodiment, the control unit 240 performs processing related to access restrictions, etc. Alternatively, the signal transmission-related functions of the control unit 240 may be included in the transmitting unit 210, and the signal reception-related functions of the control unit 240 may be included in the receiving unit 220.

[0093] (Hardware structure)

[0094] The block diagrams used in the description of the above embodiments ( Figure 4 and Figure 5The diagram illustrates blocks organized by function. These functional blocks (components) are implemented through any combination of at least one of hardware and software. Furthermore, there are no particular limitations on the implementation method of each functional block. That is, each functional block can be implemented using a single device that is physically or logically combined, or by directly or indirectly (e.g., using wired, wireless, etc.) connecting two or more physically or logically separate devices. Functional blocks can also be implemented by combining software within one or more of the aforementioned devices.

[0095] The functions include judgment, decision, determination, calculation, calculation, processing, derivation, investigation, search, confirmation, receiving, sending, output, access, resolution, selection, selection, establishment, comparison, assumption, expectation, consideration, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assigning, but are not limited to these. For example, the functional block (structural part) that performs the sending function is called the transmitting unit or transmitter. In short, as mentioned above, there are no particular limitations on the implementation method.

[0096] For example, in one embodiment of this disclosure, the base station 10, network node 30, terminal 20, etc., can also function as a computer for processing the wireless communication method of this disclosure. Figure 6 This diagram illustrates an example of the hardware structure of a base station 10 and a terminal 20 according to one embodiment of this disclosure.

[0119] Based on the above structure, in a communication system, access restrictions can be implemented separately for terminals that access using a configuration profile, distinguishing them from those that access using a configuration profile.

[0120] Alternatively, when the control unit performs access using a priority configuration profile, it derives a second access identifier corresponding to the access using the priority configuration profile and a second cause value corresponding to the second access identifier, and determines that it can access the network restricted by the restriction information. The transmitting unit then sends a wireless connection configuration request containing the second cause value to the base station.

[0122] Furthermore, according to an embodiment of the present invention, a base station is provided, comprising: a receiving unit that receives from a network node a message containing a request for access reduction other than terminals accessing using a setting profile; a control unit that calculates an access authorization ratio for terminals accessing using a setting profile based on the access reduction ratio contained in the message; and a sending unit that sends to a terminal restriction information containing the access authorization ratio, restricting terminals accessing using a setting profile.

[0123] Based on the above structure, in a communication system, access restrictions can be implemented separately for terminals that access using a configuration profile, distinguishing them from those that access using a configuration profile.

[0124] Furthermore, according to an embodiment of the present invention, a base station is provided, comprising: a receiving unit that receives from a network node a message containing a request for access reduction other than terminals accessing using a configuration profile; a control unit that calculates an access authorization ratio for terminals accessing using a configuration profile based on the access reduction ratio contained in the message; and a receiving unit that receives from a terminal a wireless connection setting request containing a cause value, the cause value indicating that access was using a configuration profile, wherein the control unit performs access restriction on the terminal that sent the wireless connection setting request based on the access authorization ratio.

[0125] Based on the above structure, in a communication system, access restrictions can be implemented separately for terminals that access using a configuration profile, distinguishing them from those that access using a configuration profile.

[0126] Furthermore, according to an embodiment of the present invention, a communication method is provided, which is executed by a terminal, the communication method comprising the following steps: receiving from a base station restriction information restricting a terminal from accessing the network using a configuration profile; when access using a configuration profile is performed, deriving a first access identifier corresponding to the access using the configuration profile and a first cause value corresponding to the first access identifier, and obtaining a first confirmation result related to whether access to the network restricted by the restriction information is possible based on the first access identifier; and if the first confirmation result indicates that access is possible, sending a wireless connection setting request including the first cause value to the base station.

[0127] Based on the above structure, in a communication system, access restrictions can be implemented separately for terminals that access using a configuration profile, distinguishing them from those that access using a configuration profile.

Items described in two or more items may be combined as needed, and items described in one item may be applied to items described in another item (as long as there is no contradiction). The boundaries of functional units or processing units in the functional block diagram do not necessarily correspond to the boundaries of physical components. Multiple functional units may be operated by a single physical component, or a single functional unit may be operated by multiple physical components. Regarding the processing described in the embodiments, the order of processing may be interchanged unless there is a contradiction. For ease of explanation, a functional block diagram is used to illustrate the base station 10 and terminal 20, but such a device may also be implemented by hardware, software, or a combination thereof.

[0130] Furthermore, the notification of information is not limited to the forms / implementations described in this disclosure, and other methods may also be used. For example, information notification may be implemented through physical layer signaling (e.g., DCI (Downlink Control Information), UCI (Uplink Control Information)), higher layer signaling (e.g., RRC (Radio Resource Control) signaling, MAC (Medium Access Control) signaling), broadcast information (MIB (Master Information Block), SIB (System Information Block)), other signals, or combinations thereof.

[0132] The processing procedures, timing, and flow of the various forms / implementations described in this specification may be rearranged in order, provided there is no contradiction. For example, the elements of various steps are indicated using an illustrative order for the methods described in this disclosure, but are not limited to the specific order indicated.

[0133] In this specification, certain actions performed by base station 10 may sometimes also be performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes having base station 10, it is obvious that various actions performed to communicate with terminal 20 can be performed by at least one of base station 10 and other network nodes besides base station 10 (e.g., considering MME or S-GW, but not limited to these). The above example illustrates the case where there is one other network node besides base station 10, but other network nodes can also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0134] The information or signals described in this disclosure can be output from a higher (or lower) layer to a lower (or higher) layer. They can also be input or output via multiple network nodes.

[0135] Input or output information can be stored in a specific location (e.g., memory) or managed using a management table. Input or output information can be overwritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0136] The determination in this disclosure can be made by a value represented by 1 bit (0 or 1), by a Boolean value (Boolean: true or false), or by a comparison of numerical values ​​(e.g., a comparison with a predetermined value).

[0137] Software, whether called software, firmware, middleware, microcode, hardware description language, or by other names, should be broadly interpreted as referring to commands, command sets, code, code segments, program code, programs, subroutines, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0138] In addition, software, commands, information, etc., can be sent and received via a transmission medium. For example, when software is sent from a webpage, server, or other remote source using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) etc.) and wireless technologies (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.

For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc., that may be involved in the above description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.

[0140] Furthermore, the terms used in this disclosure and those necessary for understanding this disclosure may be replaced with terms that have the same or similar meanings. For example, at least one of the channel and symbol may also be a signal (signaling). Additionally, a signal may also be a message. Furthermore, a component carrier (CC) may also be referred to as carrier frequency, cell, frequency carrier, etc.

[0141] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0142] Furthermore, the information, parameters, etc., described in this disclosure can be represented using absolute values, relative values ​​to predetermined values, or other corresponding information. For example, wireless resources can be indicated using indexes.

[0143] The names used for the above parameters are non-limiting in any respect. Furthermore, the formulas, etc., using these parameters sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by all appropriate names, therefore the various names assigned to these channels and information elements are non-limiting in any respect.

[0144] In this disclosure, the terms "base station (BS)," "wireless base station," "base station device," "fixed station," "NodeB," "eNodeB (eNB)," "gNodeB (gNB)," "access point," "transmission point," "reception point," "transmission / reception point," "cell," "sector," "cell group," "carrier," and "component carrier" are used interchangeably. Sometimes, terms such as macro cell, small cell, femtocell, and picocell are also used to refer to base stations.

[0145] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, its coverage area can be divided into several smaller areas, each of which can provide communication services through a base station subsystem (e.g., a small indoor cell tower (RRH: Remote Radio Head)). Terms such as "cell" or "sector" refer to a portion or all of the coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0146] In this disclosure, the base station sending information to the terminal can also be replaced by the base station instructing the terminal on information-based control / actions.

[0147] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.

[0148] For mobile stations, those skilled in the art sometimes also use the following terms: subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handheld device, user agent, mobile client, client, or some other appropriate terms.

[0149] At least one of the base station and mobile station can also be referred to as a transmitting device, receiving device, communication device, etc. Furthermore, at least one of the base station and mobile station can also be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to a movable object with an arbitrary speed of movement. It also includes situations where the mobile body is stationary. Examples of mobile bodies include, but are not limited to, vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, rear cars, rickshaws, ships (ships and other watercraft), airplanes, rockets, artificial satellites, Drone (registered trademark), multi-rotor helicopters, quadcopter helicopters, balloons, and objects mounted on them. Additionally, the mobile body can also be a mobile body that moves autonomously based on operating commands. It can be a means of transportation (e.g., car, airplane), a mobile body that moves unmanned (e.g., drone, autonomous vehicle), or a robot (humanized or unmanned). Furthermore, at least one of the base station and mobile station also includes devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station can be an IoT (Internet of Things) device such as a sensor.

[0150] Furthermore, the base station in this disclosure can also be replaced by a user terminal. For example, the communication between the base station and the user terminal can be replaced by communication between multiple terminals 20 (e.g., D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.), and various forms / implementations of this disclosure can also be applied. In this case, the terminal 20 can also be configured to have the functions of the base station 10 described above. In addition, terms such as "uplink" and "downlink" can be replaced with terms corresponding to inter-terminal communication (e.g., "side"). For example, uplink channel, downlink channel, etc., can also be replaced with side channel.

[0151] Similarly, the user terminal in this disclosure can also be replaced by a base station. In this case, the base station can also be configured to have the functions of the aforementioned user terminal.

[0152] As used in this disclosure, terms such as "determining" and "determining" sometimes encompass a variety of actions. For example, "determining" or "determining" may include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining, which are considered as actions of "determining" or "determining." Furthermore, "determining" or "determining" may include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in storage), which are considered as actions of "determining" or "determining." Additionally, "determining" or "determining" may include actions such as resolving, selecting, choosing, establishing, and comparing, which are considered as actions of "determining" or "determining." That is, "judgment" and "decision" can include matters that are considered as having been "judged" or "decided". In addition, "judgment (decision)" can also be replaced by "assuming", "expecting", "considering", etc.

[0153] The terms “connected,” “coupled,” or any variations thereof are intended to indicate any direct or indirect connection or combination between two or more elements, including cases where there is one or more intermediate elements between the two elements that are “connected” or “coupled.” The combination or connection between elements can be physical, logical, or a combination of these. For example, “access” can be used instead of “connected.” In the context of this disclosure, it can be understood that two elements are “connected” or “coupled” to each other using at least one of one or more wires, cables, and printed electrical connections, and, as some non-limiting and non-inclusive examples, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (including both visible and invisible regions) to “connect” or “couple” to each other.

[0154] The reference signal can be simply called RS (Reference Signal), or, depending on the standard applied, pilot.

[0155] As used in this disclosure, the word "based on" does not mean "based on only" unless otherwise expressly stated. In other words, the word "based on" means both "based on only" and "based on at least".

[0156] Any reference to elements using the designations "first," "second," etc., as used in this disclosure does not necessarily limit the number or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, references to the first and second elements do not imply that only two elements can be taken, or that the first element must precede the second element in any form.

[0157] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0158] When the terms "include," "including," and their variations are used in this disclosure, these terms, like the term "comprising," imply inclusion. Furthermore, the term "or" as used in this disclosure does not refer to XOR.

[0159] In this disclosure, for example, in cases where articles are added through translation, such as in English (e.g., a, an, and the), this disclosure may also include cases where the noun following these articles is in a plural form.

[0160] In this disclosure, the phrase "A and B are different" can mean "A and B are not the same." Furthermore, this phrase can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."

[0161] The various forms / implementations described in this disclosure can be used individually or in combination, and can be switched depending on the execution. Furthermore, the notification of predetermined information (e.g., a "It is X" notification) is not limited to being explicit, but can also be implicit (e.g., not notifying the predetermined information).

[0162] The present disclosure has been described in detail above, but it will be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented as modifications and variations without departing from the spirit and scope of the present disclosure as defined by the claims. Therefore, the present disclosure is for illustrative purposes only and is not intended to be limiting.

Claims

1. A terminal having: a reception section that receives, from a base station, restriction information that restricts terminals that access using a setting profile; a control section that, in a case where access using a setting profile is performed, derives a first access identification corresponding to the access using the setting profile and a first reason value corresponding to the first access identification, and acquires a first confirmation result related to whether or not a network restricted by the restriction information can be accessed, based on the first access identification; and a transmission section that, in a case where the first confirmation result is that access is possible, transmits, to the base station, a wireless connection setting request that includes the first reason value.

2. The terminal according to claim 1, wherein the control section, in a case where access using a setting profile for priority is performed, derives a second access identification corresponding to the access using the setting profile for priority and a second reason value corresponding to the second access identification, and judges that a network restricted by the restriction information can be accessed, the transmission section transmits, to the base station, a wireless connection setting request that includes the second reason value.

3. A base station having: a reception section that receives, from a network node, a message that includes a request for access reduction other than terminals that access using a running profile; a control section that calculates a proportion of access authorization of terminals that access using a setting profile, based on a proportion of the access reduction included in the message; and a transmission section that transmits, to a terminal, restriction information that restricts terminals that access using a setting profile, including the proportion of the access authorization.

4. A base station having: a reception section that receives, from a network node, a message that includes a request for access reduction other than terminals that access using a running profile; a control section that calculates a proportion of access authorization of terminals that access using a setting profile, based on a proportion of the access reduction included in the message; and a reception section that receives, from a terminal, a wireless connection setting request that includes a reason value that indicates access using a setting profile, the control section performs access restriction for the terminal that transmitted the wireless connection setting request, based on the proportion of the access authorization.

5. A communication method performed by a terminal, the communication method having the steps of: receiving, from a base station, restriction information that restricts terminals that access using a setting profile; in a case where access using a setting profile is performed, deriving a first access identification corresponding to the access using the setting profile and a first reason value corresponding to the first access identification, and acquiring a first confirmation result related to whether or not a network restricted by the restriction information can be accessed, based on the first access identification; and in a case where the first confirmation result is that access is possible, transmitting, to the base station, a wireless connection setting request that includes the first reason value. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​
