Description

Technical Field

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

[0002] In the 3rd Generation Partnership Project (3GPP), to further increase system capacity, increase data transmission speed, and reduce latency in the radio space, research is being conducted on a wireless communication method known as 5G or NR (hereinafter referred to as "5G" or "NR"). In 5G, various wireless technologies are being researched to meet the requirements of achieving throughput of over 10Gbps and achieving latency of less than 1ms in the radio space.

[0003] In NR, network architectures are being studied that include 5GC (5G Core Network), which corresponds to the core network EPC (Evolved Packet Core) in the LTE (Long Term Evolution) network architecture, and NG-RAN (Next Generation-Radio Access Network), which 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).

[0004] Furthermore, in 3GPP Rel-19, a robust notification alert function was studied as a function to notify terminals of incoming voice calls when the radio wave conditions are so poor that normal paging signals cannot reach the satellite.

[0027] 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 following embodiments.

[0028] In the operation of the wireless communication system according to embodiments of the present invention, existing technologies are appropriately used. However, such existing technologies include, but are not limited to, existing LTE. Furthermore, the term "LTE" as used in this specification has a broad meaning, unless otherwise specified, including LTE-Advanced and subsequent methods (e.g., NR), or wireless LAN (Local Area Network).

[0029] Furthermore, 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.

[0030] 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, 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 refer to either a logical connection or a physical connection.

[0031] The RAN (Radio Access Network) is a network node 30 with radio access capabilities, which may include a base station 10 and connect 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 with functions such as PDU (Protocol Data Unit) session points interconnected with the DN (Data Network), packet routing and forwarding, and QoS (Quality of Service) processing for the user plane. The UPF and DN constitute a network slice. Multiple network slices are constructed in the wireless communication network of this embodiment.

[0032] 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).

The NEF (Network Function Provider Function) is a network node 30 with the ability to notify other NFs (Network Functions) and handle 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 allowed NSSAI (Network Slice Selection Assistance Information), determining the set NSSAI, and determining the set of AMFs to which the UE connects. The PCF (Public Network Function Provider Function) is a network node 30 with the function of controlling network policies. 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.

[0034] 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, it is assumed that each function corresponds to one network node 30, but it is also possible that one network node 30 implements multiple functions, or multiple network nodes 30 implement one function. Furthermore, the term "connection" as used below can refer to either a logical connection or a physical connection.

[0035] 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 with functions such as PDU session points interconnected with the DN, packet routing and forwarding, and user plane QoS processing. The UPF and DN constitute a network slice. Multiple network slices are constructed in the wireless communication network of this embodiment.

[0036] 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 Namf, Nsmf, Nnssf, Nnef, Nnrf, Nudm, Nausf, Npcf, and Naf based on their respective services.

[0037] 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 allowed NSSAI (Network Service Access Optimization), determining the configured NSSAI, and determining the set of AMFs to which the UE connects. The PCF (Network Processing Function) is a network node 30 with the function of controlling network policies.

The NRF (Network Provider Function) is a network node 30 with the function of discovering NF instances that provide services. The SEPP (Secure Provider Optimization Program) is a non-transparent proxy that filters 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.

[0038] like Figure 2 As shown, the UE is in a roaming environment connected to the RAN and AMF within a VPLMN (Visited PLMN). The VPLMN and HPLMN (Home PLMN) are connected via vSEPP and hSEPP. For example, the UE can communicate with the UDM of the HPLMN via the AMF of the VPLMN.

[0039] Furthermore, in 3GPP Rel-19, a robust notification alert function was studied as a function to notify terminals of incoming voice calls when the radio wave conditions are so poor that normal paging signals cannot reach the satellite.

[0040] (Example)

[0041] In this embodiment, the process by which a terminal can receive information from a public warning system even under poor radio wave conditions in a wireless communication system is described. The terminal typically receives system information blocks (SIBs) containing information related to public warning systems (PWS) such as the Earthquake and Tsunami Warning System (ETWS) upon paging. These system information blocks are, for example, SIB6, SIB7, and SIB8 (see Non-Patent Document 2). On the other hand, robust notification warnings are transmitted only through a downlink physical channel that operates at a lower SNR (Signal to Noise Ratio) than the usual NR, and which contains system information and / or synchronization signals. Robust notification warnings can also be referred to as robust paging notification warnings.

[0042] In this embodiment, CBE (Cell Broadcast Entity) 30B and CBC (Cell Broadcast Centre) 30C determine an alarm message for an earthquake or tsunami, and request the base station 10 via AMF 30A to send the alarm message as a robust notification warning to the terminal 20. For details regarding CBE 30B and CBC 30C, please refer to Non-Patent Document 3. The base station 10 uses a downlink channel for sending robust notification warnings to send the alarm message. The terminal 20 can use this downlink channel to receive the alarm message even in conditions of poor radio wave conditions. Furthermore, based on the content of the received warning message, the terminal 20 performs actions such as displaying the warning message and sounding a notification tone.

[0043] The processing in this embodiment will be described in detail below with reference to the timing diagram. Figure 3 This is a diagram illustrating an example of a first timing diagram in an embodiment of the present invention. This timing is based on the warning message issuance process (see section 9.1.3.5.2 of Non-Patent Document 4). Hereinafter, [the following will describe...] Figure 3 The process of each step is explained.

[0044] S101: CBE30C sends a message to CBC30B requesting the broadcast of an alarm message from the public alarm system for earthquakes or tsunamis (emergency broadcast request).

[0045] S102: CBC30B decides to also use robust notification alerts to broadcast alert messages from the public alert system to terminal 20, and sets an information element (IE) related to the type and content of the alert message used for robust notification alerts. The size of this information element can be determined to be a limited size (e.g., smaller than the size of the setting information used in the alert message sent in the system information). In addition, the information element may also include instructions related to the behavior of terminal 20 (such as beeping and popping up) and information related to the content of the pop-up.

[0046] S103: CBC30B sends a request message (Namf_NonUeN2Message Transfer request, see sections 6.1.3.8.4.2.2 and 6.1.6.2.9 of Non-Patent Document 5 and section 9.2.8.1 of Non-Patent Document 6) to AMF30A. This request message requests the forwarding of a message containing information elements related to the type and content of the alarm message for robust notification warning, as set in S102. This request message is, for example, expressed as Namf_NonUeN2Message Transfer request(N2InformationTransferReqData(n2Information(Write-Replace Warning Request(Warning Type and Warning Message Contents for robust notification alert)))).

[0047] S104: AMF30A sends a response message (Namf_NonUeN2Message Transfer response) to CBC30B in response to the request message received in S103.

[0048] S105: CBC30B sends a response message (emergency broadcast response) to CBE30C in response to the request message received in S101.

[0049] S106: AMF30A sends a request message (Write-Replace Warning Request) to base station 10. This request message contains information elements related to the type and content of the alarm message used for robust notification warning, as set in S102. For example, this request message can be described as Write-Replace Warning Request (Warning Type and Warning MessageContents for robust notification alert).

[0050] S107: Based on the request message received in S106, base station 10 broadcasts system information (e.g., SIB6, SIB7, and SIB8) containing alarm messages from the public alarm system, according to existing standard paging. That is, terminal 20 receives the alarm messages broadcast from base station 10. Additionally, in cases of poor radio conditions (e.g., inability to correctly receive paging messages), terminal 20 transitions to a state of receiving robust notification warnings.

[0051] S108: Based on the information elements (Warning Type and Warning Message Contents for robust notification alert) contained in the request message received in S106, base station 10 identifies a request for the sending of a robust notification alert.

[0052] S109: In the downlink channel used for sending robust notification alerts, base station 10 broadcasts a robust notification alert based on information elements related to the category and content of the alert message for robust notification alerts contained in the request message received in S106. That is, terminal 20 receives the robust notification alert broadcast from base station 10 containing this information element. In addition, based on this information element, terminal 20 performs display and sounding related to the robust notification alert (i.e., displaying the alert message on the screen and outputting a notification sound, etc.).

[0053] S110: Base station 10 sends a response message (Write-Replace Warning Response, see section 9.2.8.2 of Non-Patent Document 6) to AMF30A in response to the request message received in S106. This response message contains a list of information indicating the areas where robust notification alerts were broadcast in S109, for example, labeled Write-Replace WarningResponse (Robust notification alert Completed Area List).

[0054] S111: AMF30A sends a request message (Namf_NonUeN2InfoNotify request, see sections 6.1.5.3.3.1, 6.1.6.2.14, 6.1.6.2.15, and 6.1.6.2.29 of Non-Patent Document 5 and section 9.2.20 of Non-Patent Document 4) to CBC30B. This request message contains a list of information received in S110 indicating areas where robust notification warnings have been broadcast. This request message is represented, for example, as Namf_NonUeN2InfoNotify request(N2InformationNotification(n2InfoContainer(PwsInformation(pwsContainer(Write-Replace-Warning-Indication(Robust notification alert Scheduled AreaList)))))).

[0055] According to the above embodiments, in a wireless communication system, even under poor radio wave conditions, the terminal can receive information related to the public alarm system.

In addition, the setting unit 230 also stores pre-set setting information. The content of the setting information includes, for example, information related to communication lines in the IMS network.

[0108] In this specification, certain actions described as being performed by base station 10 may sometimes be performed through 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., MME or S-GW, but not limited to these). The above example illustrates a single network node other than base station 10, but other network nodes can also be a combination of multiple other network nodes (e.g., MME and S-GW).

[0109] It can output information or signals described in this disclosure from a higher (or lower) layer to a lower (or higher) layer. It can also be input or output via multiple network nodes.

[0110] 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 rewritten, updated, or appended. Output information can also be deleted. Input information can also be sent to other devices.

[0111] 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).

[0115] 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 a carrier frequency, cell, frequency carrier, etc.

[0116] The terms “system” and “network” as used in this disclosure are used interchangeably.

[0117] Furthermore, the information, parameters, etc., described in this disclosure can be represented using absolute values, relative values ​​relative to predetermined values, or other corresponding information. For example, wireless resources can also be indicated by indexes.

[0118] The names used for the parameters described above are not limiting names in any way. Furthermore, the formulas, etc., using these parameters sometimes differ from those explicitly disclosed in this disclosure. Since various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by all appropriate names, the various names assigned to these various channels and information elements are not limiting names in any way.

[0119] In this disclosure, the terms "base station (BS)," "wireless base station," "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.

[0120] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, and each smaller area 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 the entire coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

This also includes situations where the mobile body is stationary. Examples of mobile bodies include vehicles, transport vehicles, automobiles, motorcycles, bicycles, connected cars, excavators, bulldozers, wheel loaders, dump trucks, forklifts, trains, buses, handcarts, rickshaws, ships (ships and other watercraft), airplanes, rockets, artificial satellites, drones (registered trademark), multicopters, quadcopters, hot air balloons, and objects mounted on them, and are not limited to these. Furthermore, the mobile body can also be a mobile body that moves autonomously based on operating commands. The mobile body can be a means of transportation (e.g., automobiles, airplanes, etc.), a mobile body that moves unmanned (e.g., drones, autonomous vehicles, etc.), or a robot (humanized or unmanned). In addition, at least one of the base station and mobile station also includes devices that are not necessarily mobile during communication operations. For example, at least one of the base station and mobile station can be an IoT (Internet of Things) device such as a sensor.

[0125] Furthermore, the base station in this disclosure can also be replaced by a user terminal. For example, various forms / implementations of this disclosure can be applied to a structure that replaces the communication between the base station and the user terminal with communication between multiple terminals 20 (e.g., also referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). 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.

For example, "determining" and "determining" can 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" and "determining." Furthermore, "determining" and "determining" can 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" and "determining." Additionally, "determining" and "determining" can include actions such as resolving, selecting, choosing, establishing, and comparing, which are considered as actions of "determining" and "determining." That is, "judgment" and "decision" can include matters that are considered to have been "judged" or "decided" to take certain actions. In addition, "judgment (decision)" can also be replaced by "assuming", "expecting", "considering", etc.

[0128] 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 (both visible and invisible) region to “connect” or “couple” to each other.

[0129] The reference signal can be simply referred to as RS (Reference Signal), or, depending on the applicable specifications, as a pilot.

[0130] 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".

[0131] 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 way to distinguish 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 in some forms the first element must precede the second element.

[0132] Alternatively, the "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0133] 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 implies non-exclusivity.

[0134] 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.

[0135] In this disclosure, the phrase "A and B are different" can also 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."

[0136] The various forms / implementations described in this disclosure can be used individually, in combination, or switched during execution. Furthermore, the notification of predetermined information is not limited to explicit notification (e.g., a "Yes X" notification) but can also be implicit notification (e.g., not notifying the predetermined information).

[0137] 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.
