Description

Technical Field

[0001] This invention relates to network nodes 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 (5G Core Network) corresponds to the core network EPC (Evolved Packet Core) in the LTE (Long Term Evolution) network architecture, and the NG-RAN (Next Generation-Radio Access Network) corresponds to the RAN (Radio Access Network) E-UTRAN (Evolved Universal Terrestrial Radio Access Network) in the LTE network architecture (e.g., Non-Patent Literature 1 and Non-Patent Literature 2).

[0009] The problem that the invention aims to solve

[0010] In wireless communication systems, research is underway on virtual personalities acting as agents for AI (Artificial Intelligence). It is envisioned that opportunities to communicate with these virtual personalities will increase in the future. Here, when both the cyberspace containing the virtual personality and the real space containing the real user coexist, there is no mechanism to determine which space to connect to—the real space or the cyberspace.

[0011] The present invention was made in view of the above-mentioned problems, and its object is to determine or notify the connection target based on the situation in a wireless communication system.

[0025] 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.

[0026] 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).

[0027] 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.

[0028] Figure 1 This is a diagram used to illustrate an example of a communication system. For example... Figure 1 As 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.

[0029] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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, Nnssf, Nnef, Nnrf, Nudm, Nausf, Npcf, and Naf.

[0035] 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 Provider Function) is a network node 30 with the ability to notify other NFs and handle events. The NSSF (Network Provider Function) 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 Service 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 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.

[0036] 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.

[0037] Figure 3 This is a diagram used to illustrate an example of an IMS data channel network. For example... Figure 3 As shown, the IMS data channel network consists of a UE (user equipment) as a terminal 20 and multiple network nodes 30 in both the calling side network and the terminating side network. Hereinafter, it is assumed that each function corresponds 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 be a logical connection or a physical connection. For example, the network node 30 has the following functions as described in Non-Patent Document 3.

[0038] IMS-AGW (Access Gateway) is a network node 30 that functions as a gateway between the UE and the IMS network.

[0039] P-CSCF (Proxy-Call Session Control Function) is a network node 30 that has proxy functions between the UE and the IMS network.

[0040] S-CSCF (Serving-Call Session Control Function) is a network node 30 that has functions related to session control for the UE.

[0041] The I-CSCF (Interrogate-Call Session Control Function) is the connection point between networks in an IMS network (e.g., the calling side and the called side) on the called side, such as a network node 30 that has the function of forwarding received SIP requests to its own network via an S-CSCF.

[0042] The IMS AS (IP Multimedia Subsystem Application Server) is a network node 30 in the IMS network that has the functions of communicating with the DCSF for event notification and receiving data channel control instructions from the DCSF to communicate with the MF. Additionally, the IMS AS receives registration requests from communication endpoints from the DCSF, converts the received registration requests into SIP Registers, and sends them to the S-CSCF. Furthermore, the IMS AS converts data channel establishment requests received from the DCSF into SIP Invitations and sends them to the S-CSCF.

[0043] DCSF (Data Channel Signalling Function) is a network node 30 that has functions such as receiving event reports from IMS-AS and deciding whether to allow the provision of data channel services, managing the data channel, and HTTP web server functions.

[0044] MF (Media Function) is a network node 30 in the IMS network that has functions such as media resource management and forwarding of media traffic on the data channel. Furthermore, based on configuration information received from DCSF, MF processes media between the DCAS (Data Channel Application Server), which acts as the communication endpoint, and the destination endpoint. MF can also be called DCMF (Data Channel Media Function). Additionally, MF can also be MRF (Multimedia Resource Function).

[0045] DCAS (Data Channel Application Server) is a network node 30 that has functions such as terminating media and signaling-related communications in the IMS network.

[0046] Figure 3 This is a diagram illustrating an example (1) of communication in an embodiment of the present invention. Figure 3 As shown, the communication venue can be expanded from physical space to cyberspace. The barriers between physical and cyberspace can also be removed, making communication paths redundant and robust. Furthermore, cyberspace can be the space on the network or the space on the Internet.

[0047] A real user A in cyberspace is designated as virtual personality A, and a real user B in cyberspace is designated as virtual personality B. A virtual personality refers to an existence in cyberspace that accurately reproduces a person's opinions, questions, and actions. Alternatively, it can be an existence that perceives the same intellect and personality as a real person, allowing the virtual personality to be recognized and act as such in society. For example, a virtual personality can function as a clone of the person in office work, enabling the person to engage in activities outside of work. Furthermore, through virtual personalities, encounters and connections with people can be created, thereby building interpersonal relationships for living authentically. For example, a virtual personality can also be configured on a data channel application server (DCApplication Server, see Non-Patent Document 3) to perform communication. Alternatively, for example, a virtual personality can be pre-downloaded and configured within a terminal to perform communication.

[0048] For example, the technology of automatically generating casual responses by considering the attributes of the real speaker and the topic can be applied to virtual personalities as the content of their speech. Additionally, the technology of reproducing an individual's voice based on a small amount of their learning data can be applied to virtual personalities. Furthermore, the technology of automatically generating movements consistent with an individual's speaking voice and content based on a record of their movements at the time of speaking can also be applied to virtual personalities.

[0049] For example, when a network communication failure occurs between real user B and the network, communication between real user A and real user B becomes impossible. On the other hand, communication between virtual persona A and virtual persona B in cyberspace can continue. Furthermore, communication between virtual persona B and real user A in cyberspace can continue. Additionally, communication between virtual persona A, pre-downloaded to real user B's terminal, and real user B can continue. Virtual persona A, pre-downloaded to real user B's terminal, can also reside in cyberspace.

[0050] Here, we envision that the opportunities for communication with virtual personalities acting as AI agents, as described above, will increase in the future. When a cyberspace containing such a virtual personality and a real space containing real users coexist, there is no mechanism to select the called party as either the real or the cyberspace based on the user's circumstances.

[0051] Furthermore, this virtual persona is a proxy that replicates the real person, and its speech pattern and voice are similar to the real person's. From a reassurance and security perspective, it is necessary to notify users which connection they are making in both the real and cyberspace, and furthermore, which entity they are communicating with after connecting.

[0052] Figure 4 This is a diagram illustrating an example (1) of communication in an embodiment of the present invention. Figure 4 As shown, when a real user A makes a call to B, the network can route the call to either the real user B in the real space or the virtual persona B in the network space, based on B's status, such as its residency status or settings. Alternatively, user A can be associated with either real user A or virtual persona A, and user B can be associated with either real user B or virtual persona B.

[0053] In addition, real user A may sometimes be unsure whether the connection target is the network or the real device, so the network can also notify real user A whether the connection target is the network or the real device.

[0054] For example, you can also perform the following 3 steps.

[0055] Step 1) In order to determine the connection target, the core network determines the called party's domain as either the physical space or the network space, based on priority domain data and the actual user's residency status.

[0056] Step 2) Inform the caller of the determined called domain (also known as the connection target domain or called domain), so that the caller can identify which connection in the real space or cyberspace.

[0057] Step 3) The network notifies the caller of the following information: that the caller can identify the conversation as being with cyberspace. For example, this could include changing the audio quality of the voice during the call, periodically outputting warning tones, or causing the caller's terminal to vibrate. Furthermore, not limited to the conversation itself, the network can also notify the caller of the following information: that the caller can identify the communication as being with cyberspace.

[0058] Figure 5 This is a timing diagram illustrating example (2) of communication in an embodiment of the present invention. Using Figure 5 Explain the detailed process of the above three steps.

[0059] In step S101, terminal 20A of real user A sends a connection request to user B to the calling side switch CSCF 30A. In step S102, the calling side switch CSCF 30A sends a query for user information related to user B to the subscriber database HSS (Home Subscriber Server) or UDM 30B.

[0060] In steps S103 to S105, the called domain selection process is performed. In step S103, the subscriber database HSS or UDM 30B sends a called terminal registration query related to user B to the called-side switch CSCF 30C. The called-side switch CSCF 30C sends a response containing called terminal registration information related to user B to the subscriber database HSS or UDM 30B.

[0061] In step S105, the subscriber database HSS or UDM 30B determines the called party's domain as either physical space or network space based on priority domain data and residency status.

[0062] For example, the called party user can also set the called party domain, similar to a voicemail or call transfer. Additionally, the subscriber database HSS or UDM 30B can determine the called party domain as the network space based on time periods. Furthermore, the subscriber database HSS or UDM 30B can also determine the called party domain as the network space based on the user's online status; for example, it can determine the called party domain as the network space when the actual user is not online, or it can determine the called party domain as the online space when the actual user is online. Additionally, the subscriber database HSS or UDM 30B can also determine the called party domain as the network space based on disaster status; for example, it can determine the called party domain as the network space when the actual user is in a disaster state, or it can determine the called party domain as the online space when the actual user is in a disaster state.

[0063] Additionally, the subscriber database HSS or UDM 30B can determine the called party's domain as the network space when the real user is on a call, and can switch the called party's domain from the network space to the real space after the real user's call ends. Furthermore, if the called party user has granted the caller ID authorization to use the network space, the called party's domain can also be set as the network space. Conversely, if the called party user has granted the caller ID authorization to use the real space, the called party's domain can also be set as the real space.

[0064] Additionally, the subscriber database HSS or UDM 30B can also set the called party's domain as the real space when the called party user is registered and has set both the real space and network space to be callable. Alternatively, the subscriber database HSS or UDM 30B can also set the called party's domain as the network space when the called party user is registered and has set both the real space and network space to be uncallable. Furthermore, the subscriber database HSS or UDM 30B can also set the called party's domain as the network space when the called party user is not registered and has set both the real space and network space to be callable. Finally, the subscriber database HSS or UDM 30B can also set the called party's domain as the network space when the called party user is not registered and has set both the real space and network space to be uncallable.

[0065] In step S106, the subscriber database HSS or UDM 30B sends a called party domain notification to the calling-side switch CSCF 30A. In step S107, the calling-side switch CSCF 30A sends a called party domain notification to the terminal 20A of the actual user A.

[0066] If the called party's domain is a physical space, in step S108A, the calling side switch CSCF 30A sends a connection request to the physical space to the called side switch CSCF 30C. In the following step S109A, the called side switch CSCF 30C performs connection processing from the terminal 20A of the physical user A to the physical user B.

[0067] On the other hand, when the called party's domain is cyberspace, in step S108B, the calling side switch CSCF30A sends a connection request to cyberspace to the called side switch CSCF 30D. In the following step S109B, the called side switch CSCF 30D performs connection processing from the real user A's terminal 20A to the virtual persona B.

[0068] In step S110B, the real user A's terminal 20A and the virtual personality B conduct a session. Additionally, in step S110B, the network notifies the real user A's terminal 20A of the following information: the caller can recognize that the call is in cyberspace during the session. For example, the network can change the audio quality of the call, periodically output warning tones, or cause the caller's terminal to vibrate. For example, the called party CSCF 30D can notify the real user A's terminal 20A of the following information: the caller can recognize that the call is in cyberspace during the session; this notification can also be sent by other network nodes.

[0069] According to the above embodiments, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space based on the situation, and notifies the calling real user. This allows the calling real user to identify which virtual persona or real user they are connecting with. Furthermore, the calling real user is notified by the network that they can identify the communication as a network call, thus enabling them to identify which virtual persona or real user they are communicating with.

[0070] That is, in a wireless communication system, it is possible to determine or notify the connection target based on the situation.

[0071] (Device structure)

[0072] 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.

[0073] <Base station 10 and network node 30>

[0074] Figure 6 This is a diagram illustrating an example of the functional structure of base station 10. (As shown...) Figure 6 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 6 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.

[0075] 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.

[0076] The setting unit 130 stores pre-set setting information and various setting information sent to the terminal 20 in a storage device, and reads it from the storage device as needed. The content of the setting information is, for example, the operation-related settings described in the embodiment.

[0077] As described in the embodiment, the control unit 140 performs the operation-related processing described in the embodiment. Additionally, the control unit 140 performs processing related to communication with the terminal 20. Alternatively, the signal transmission-related functions of the control unit 140 may be included in the transmitting unit 110, and the signal reception-related functions of the control unit 140 may be included in the receiving unit 120.

[0078] Terminal 20

[0079] Figure 7 This is a diagram illustrating an example of the functional structure of terminal 20. (As shown...) Figure 7 As shown, the terminal 20 includes a transmitting unit 210, a receiving unit 220, a setting unit 230, and a control unit 240. Figure 7 The functional structure shown is only one example. The functional divisions and names of the functional units can be arbitrary, as long as the actions involved in the embodiments of this invention can be implemented.

[0080] The transmitting unit 210 generates a transmission signal based on the transmission data and transmits the transmission signal wirelessly. The receiving unit 220 wirelessly receives various signals and obtains higher-layer signals from the received physical layer signals. In addition, the receiving unit 220 has the function of receiving NR-PSS, NR-SSS, NR-PBCH, DL / UL control signals or reference signals, etc., transmitted from the network node 30.

[0081] 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. The content of the setting information includes, for example, operation-related settings as described in the embodiment.

[0082] As described in the embodiments, the control unit 240 performs the operation-related processing described in the embodiments. Additionally, the control unit 240 performs processing related to capacity enhancement cells. 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.

[0083] (Hardware structure)

[0084] The block diagrams used in the description of the above embodiments ( Figure 6 and Figure 7 The diagram illustrates blocks organized by function. These functional blocks (structural units) 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.

[0085] 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.

[0086] For example, in one embodiment of this disclosure, network node 30, terminal 20, etc., can also function as a computer for processing the wireless communication method of this disclosure. Figure 8This diagram illustrates an example of the hardware structure of a base station 10 and a terminal 20 according to one embodiment of this disclosure. The network node 30 may also have the same hardware structure as the base station 10. The base station 10 and terminal 20 can be configured as a computer device that physically includes a processor 1001, a storage device 1002, an auxiliary storage device 1003, a communication device 1004, an input device 1005, an output device 1006, and a bus 1007, etc.

[0087] Furthermore, in the following description, the term "device" can be replaced with "circuit," "device," "unit," etc. The hardware structure of base station 10 and terminal 20 can be configured to include one or more of the devices shown in the figures, or it can be configured to not include any of them.

[0088] The functions of base station 10 and terminal 20 are implemented by reading predetermined software (program) into hardware such as processor 1001 and storage device 1002, so that processor 1001 performs calculations and controls the communication of communication device 1004 or controls at least one of reading and writing data in storage device 1002 and auxiliary storage device 1003.

[0089] The processor 1001 controls the computer as a whole by instructing the operating system to operate. The processor 1001 may also be a central processing unit (CPU) that includes interfaces with peripheral devices, control units, arithmetic units, registers, etc. For example, the control unit 140 and control unit 240 described above can also be implemented using the processor 1001.

[0090] Additionally, the processor 1001 reads programs (program code), software modules, or data from at least one of the auxiliary storage devices 1003 and communication devices 1004, and performs various processes accordingly. As a program, a program is used that causes the computer to perform at least a portion of the actions described in the above embodiments. For example, Figure 6 The control unit 140 of the base station 10 shown can also be implemented by a control program stored in the storage device 1002 and operated in the processor 1001. Alternatively, for example, Figure 7 The control unit 240 of the terminal 20 shown can also be implemented by a control program stored in the storage device 1002 and operated in the processor 1001.

[0107] (Summary of implementation methods)

[0108] As described above, according to an embodiment of the present invention, a network node is provided, comprising: a receiving unit that receives from a first network node an information query relating to a connection request to a certain user; a control unit that determines the called domain of the certain user as either physical space or cyberspace; and a sending unit that sends information indicating the determined called domain to the first network node.

[0109] Based on the above structure, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space, and notifies the calling real user. This allows the calling real user to identify which connection they are making, the virtual persona or the real user. Furthermore, the calling real user is notified by the network that they are communicating with the network, thus identifying which virtual persona or the real user they are communicating with. In other words, in a wireless communication system, the connection target can be determined or the connection target can be notified based on the situation.

[0110] Alternatively, the sending unit may send an inquiry related to the user's residency information to the second network node, and the receiving unit may receive a response related to the user's residency information from the second network node. According to this structure, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space based on the situation and notifies the calling real user, thereby enabling the calling real user to identify which virtual persona or real user they are connecting with. Furthermore, the calling real user is notified by the network that they can identify that they are communicating with the network, thus identifying which virtual persona or real user they are communicating with.

[0111] Alternatively, the control unit may determine the called party domain for the user based on at least one of the user's settings, time period, dwell state, disaster state, and call state. According to this structure, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space, and notifies the calling real user, thereby enabling the calling real user to identify which virtual persona or real user they are connecting with. Furthermore, the calling real user is notified by the network that they can identify a network call during communication, thus identifying which virtual persona or real user they are communicating with.

[0112] Furthermore, according to an embodiment of the present invention, a network node is provided, comprising: a control unit that performs connection processing from a first user to a second user in the network space; and a transmission unit that, when the first user communicates with the second user in the network space, notifies the first user that the communication is with the network space.

[0113] Based on the above structure, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space, and notifies the calling real user. This allows the calling real user to identify which connection they are making, the virtual persona or the real user. Furthermore, the calling real user is notified by the network that they are communicating with the network, thus identifying which virtual persona or the real user they are communicating with. In other words, in a wireless communication system, the connection target can be determined or the connection target can be notified based on the situation.

[0114] Alternatively, the transmitting unit may control the sound or cause the first user's terminal to vibrate during a session between the first user and the second user in the network space. According to this structure, when a real user makes a call, the network selects either a virtual persona in the network space or a real user in the real space, and notifies the calling real user, thus allowing the calling real user to identify which virtual persona or real user they are connecting with. Furthermore, the calling real user is notified by the network that they can identify that they are communicating with the network, thereby recognizing which virtual persona or real user they are communicating with.

[0115] In addition, according to an embodiment of the present invention, a communication method is provided, wherein a network node performs the following process: receiving an information query from a first network node relating to a connection request to a certain user; determining the called domain of the certain user as either physical space or cyberspace; and sending information representing the determined called domain to the first network node.

[0116] Based on the above structure, when a real user makes a call, the network selects either a virtual persona in cyberspace or a real user in real space, and notifies the calling real user. This allows the calling real user to identify which connection they are making, the virtual persona or the real user. Furthermore, the calling real user is notified by the network that they are communicating with the network, thus identifying which virtual persona or the real user they are communicating with. In other words, in a wireless communication system, the connection target can be determined or the connection target can be notified based on the situation.

[0122] 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.

[0123] In this specification, specific actions performed by network node 30 may sometimes also be performed by its upper node, depending on the circumstances. In a network consisting of one or more network nodes having network node 30, various actions performed to communicate with terminal 20 can obviously be performed by at least one of network node 30 and other network nodes besides network node 30 (e.g., consider MME or S-GW, but not limited to these). The above example illustrates the case where there is only one other network node besides network node 30, but other network nodes can also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0124] 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.

[0125] 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.

[0126] 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).

[0127] 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.

[0128] 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.

[0129] The information, signals, etc., described in this disclosure can also be represented using any of a variety of different technologies. For example, the data, commands, instructions, information, signals, bits, symbols, chips, etc., that may be involved in the above description as a whole can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination of these.

[0130] 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.

[0131] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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 also provide communication services through a base station subsystem (e.g., a small indoor base station (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.

[0136] In this disclosure, the terms "Mobile Station (MS)," "user terminal," "User Equipment (UE)," and "terminal" are used interchangeably.

[0137] 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.

[0138] 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 can be a vehicle (e.g., a car, an airplane, etc.), a mobile body moving in an unmanned manner (e.g., a drone, an autonomous vehicle, etc.), or a robot (humanized or unmanned). In addition, at least one of the base station and mobile station also includes devices that do not necessarily move during communication. For example, at least one of the base station and mobile station can be an IoT (Internet of Things) device such as a sensor.

[0139] 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 network node 30 described above. In addition, terms such as "uplink" and "downlink" can be replaced with terms corresponding to communication between terminals (e.g., "side"). For example, uplink channel, downlink channel, etc., can also be replaced with side channel.

[0140] 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.

[0141] 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 memory), 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.

[0142] 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.

[0143] The reference signal can be simply called RS (Reference Signal), or, depending on the standard applied, pilot.

[0144] 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".

[0145] 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.

[0146] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0147] 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.

[0148] 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.

[0149] 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."

[0150] 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).

[0151] 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.
