AI Technical Summary
Existing wireless network technologies cannot effectively manage and control unmanned aerial vehicles (UAVs) in non-transmission zones (NTZ) and frequency band limitations, leading to spectrum compatibility issues. Furthermore, the current 5GS does not allow external entities to equip aircraft with communication strategies, making it impossible to dynamically update NTZ information.
The NEF entity in the core network provides service operations, allowing external entities to equip the core network with NTZ information and store it in the UDR. The PCF entity is used to configure UE policies, ensuring that the UAV complies with NTZ and frequency band restrictions, and dynamically updating and managing NTZ information.
It enables the core network to effectively control and manage NTZ and frequency band restrictions, ensuring that UAVs avoid cell search in NTZ and communicate using frequency bands outside the restricted frequency band, thus meeting spectrum compliance requirements.

Detailed Implementation
[0036] In the following description, certain specific details are set forth in order to provide a thorough understanding of the disclosed aspects. However, those skilled in the art will recognize that the aspects can be practiced without one or more of these specific details or using other methods, components, materials, etc. In other instances, well-known structures associated with transmitters, receivers, or transceivers have not been shown or described in detail to avoid unnecessarily obscuring the description of the aspects.
[0037] Throughout this specification, the reference to "an aspect" or "aspect" means that a particular feature, structure, or characteristic described in connection with that aspect is included in at least one aspect. Therefore, the phrases "in an aspect" or "in one respect" appearing in various places throughout this specification do not necessarily refer to the same aspect. Furthermore, a particular feature, structure, or characteristic may be combined in one or more aspects in any suitable manner.
[0038] The embodiments described in this disclosure can be implemented in wireless network devices, such as, but not limited to, devices utilizing Global Microwave Access Interoperability (WiMAX), Global System for Mobile Communications (GSM, 2G), GSM EDGE Radio Access Network (GERAN), General Packet Radio Service (GPRS), Universal Mobile Telecommunications System based on Basic Wideband Code Division Multiple Access (W-CDMA) (UMTS, 3G), High-Speed Packet Access (HSPA), Long Term Evolution (LTE), Advanced LTE, Enhanced LTE (eLTE), 5G New Radio (5G NR), 5G Advanced, 6G (and beyond), and 802.11ax (Wi-Fi 6), and other wireless network systems. The term "eLTE" here refers to LTE evolution connected to a 5G core. LTE is also referred to as Evolved UMTS Terrestrial Radio Access (EUTRA) or Evolved UMTS Terrestrial Radio Access Network (EUTRAN).
[0039] An unmanned aerial vehicle (UAV) is an aircraft that operates without an onboard human pilot and can be remotely controlled by an operator using a UAV controller. Some UAVs may also have autonomous flight capabilities. In some examples, a UAV may be a drone. An unmanned aerial system (UAS) may include one or more UAVs and one or more UAV controllers. Additionally, a UAS may communicate with an unmanned aerial system traffic management (UTM) system. A UTM system can integrate flying UAVs (multiple UAVs) with other airspace users. For example, a UTM system may provide a set of functions and services for managing a range of autonomous vehicle operations, such as certifying UAVs, authorizing UAS services, managing UAS policies, and controlling UAV traffic in the airspace.
[0040] UAS Network Functions (UAS NFs) are 3GPP (3rd Generation Partnership Project) network functions that provide services to UAVs, including authentication, flight authorization, tracking, and communications quality control. UAS Service Providers (USS) can support safe airspace use by providing services to UAS operators to meet UTM (Unified Management Module) requirements. Third-Party Authorized Entities (TPAEs) (e.g., ground control towers) can also play a role in UAS management, for example, for UAV traffic control.
[0041] In this disclosure, a UAV may include a mobile communication device capable of communicating with a wireless communication system, such as a 3GPP system (e.g., a 5G system (5GS)). The terms “UAV,” “aviation communication device,” “aircraft,” “aviation UE,” and “UAV-UE” are used interchangeably herein, such that a description referring to one of these terms should be considered as referring to the other terms as well. Furthermore, in some instances, UAV-UE may be simply referred to as UE.
[0042] In some scenarios, for spectrum compatibility purposes, it may be desirable to restrict the transmission of aeronautical communication devices (e.g., UAVs) in certain geographic areas and / or in certain frequency bands. For example, the European Conference on Postal and Telecommunications Regulation (CEPT) Decision 22 (07) outlines the technical conditions for the use of aeronautical UEs in several LTE and 5G NR bands that are harmonized for the purpose of harmonizing mobile / fixed communication networks (MFCNs), and specifically addresses operational restrictions on aeronautical UEs in the form of non-transmission zones (NTZs). According to CEPT, an NTZ is a geographic area in which aeronautical UEs are not permitted to transmit in a given MFCN band or a portion thereof for spectrum compatibility purposes. In addition to the harmonized technical conditions for MFCN bands, further definition of spectrum operational restrictions is required. For example, at the national level, NTZs may be defined for aeronautical UEs in relevant bands to ensure spectrum compliance. In some cases, it may also be necessary for the operation of aeronautical UEs to comply with relevant cross-border harmonization agreements. In one example, the LTE and 5G NR bands in 703-733 MHz, 832-862 MHz, 880-915 MHz, 1710-1785 MHz, 1920-1980 MHz, and 2500-2570 MHz, as well as the MFCN coordinated band in 2570-2620 MHz, can be considered the NTZ of an aeronautical UE. Typically, NTZ can refer to a total restriction on transmission (i.e., no permissible transmission band) or a restriction on transmission to one or more specific bands.
[0043] Given the existence of NTZs (defined by CEPT) and certain frequency bands (defined at the national level) that prohibit aviation UEs from transmitting, mechanisms are needed to ensure that aviation UEs comply with these NTZ and / or frequency band restrictions.
[0044] 3GPP Release 19 (Rel-19) introduces Enhanced Network Open Function (NEF) services to support Mobile Network Operator (MNO)-UTM data services. NEF services securely expose 3GPP core network capabilities to third parties and / or non-3GPP entities. These NEF services can assist in, but are not limited to, intelligent flight planning, monitoring, interfacing with UTM infrastructure (e.g., including multiple USSs), and Quality of Experience (QoE) estimation using 5GS. In one example, (multiple) enhanced NEF services can provide additional information to the UAV operator (or USS) to perform pre-flight preparation and in-flight operations (e.g., flight mission request, flight path recommendation, flight monitoring, and control). In another example, (multiple) enhanced NEF services can support enhanced UAV flight and / or route management based on network capacity and Quality of Service (QoS) information along the planned route. There are also recommendations from aviation industry organizations such as the GSMA and the Joint Activities for Aviation Connectivity (ACJA) to enhance service exposure to further support aviation operations.
[0045] Therefore, it may be expected that MNOs will use cellular networks as a reliable communications backbone for the aviation vertical to provide (multiple) service exposures to the aviation industry (e.g., UAS operators, UTMs, command and control connectivity service providers (C2CSPs), etc.), for example, supporting different air zones with different UAV settings and / or communication QoS.
[0046] One approach to configuring NTZ information for a UAV-UE is via an Aircraft-to-Everything (A2X) policy. For this purpose, the A2X policy can provide the UAV-UE with configuration parameters for A2X communication via a PC5 reference point (e.g., for sidelink communication) and / or via a Uu reference point (e.g., for direct communication). However, currently, 5GS does not allow A2X policies to be configured by external entities (non-3GPP entities). Furthermore, A2X policies are not currently stored in the 5GS's Unified Data Repository (UDR) but are manually configured at the 5GS's Policy Control Function (PCF) entity. Manual configuration may be unsuitable for configuring NTZ information at the 5GS because operators may not have prior knowledge of the NTZ information. Additionally, in some cases, it may be desirable to dynamically configure (or update) NTZ information based on changes in conditions (e.g., changes in conditions and / or requirements).
[0047] The terms “A2X strategy” and “UE strategy” are used interchangeably in this document, such that a description that refers to one of these terms should be regarded as referring to the other terms as well.
[0048] This disclosure provides techniques for a core network (e.g., a 5G core (5GC)) to control and manage UAV communications within NTZ and / or band-restricted areas along the UAV's flight path (e.g., pre-mission flight path and / or upcoming flight path). For example, a NEF entity associated with the core network can provide service operations (e.g., an application programming interface (API) for an external entity to equip the core network with NTZ information and store the equipped NTZ information at the UDR of the core network). A PCF entity at the core network can utilize the NTZ information stored at the UDR to configure (multiple) NTZ and / or (multiple) band restrictions for the UAV-UE. In this way, the UAV-UE can comply with the configured (multiple) NTZ and / or (multiple) band restrictions and adapt its behavior accordingly. For example, in one aspect, when the UAV-UE is in an NTZ, it can avoid performing cell search or transmission. In another aspect, when the UE is in an NTZ, the UAV-UE can transmit communication signals using frequency bands outside the restricted (multiple) transmission bands.
[0049] As used herein, the term "network function" can be a software instance executing on hardware (e.g., a network device) or a virtualized function instantiated on hardware. Furthermore, the terms "service operation" and "API" are used interchangeably herein, such that a description referring to one of these terms should be considered as referring to the other terms as well.
[0050] According to one aspect of this disclosure, a UAS Authorized Entity outside the core network can transmit an NTZ information provision request to a NEF entity within the core network to provision NTZ information to the core network. In some examples, the UAS Authorized Entity may be a USS or TPAE. The NTZ information can be configured by the core network to configure UE policies (e.g., A2X policies) for UAVs (UAV-UEs). The NTZ information may include at least one of the following: coordinate information indicating a geographic area (or airspace) (e.g., a list of coordinates including longitude, latitude, and / or altitude information), a flag value indicating whether the NTZ applies to the geographic area, frequency information associated with one or more permitted transmission bands, frequency information associated with one or more restricted transmission bands, or information associated with the time period to which the NTZ applies. In some instances, the geographic area may be along the UAV's pre-mission flight path. In other instances, the geographic area may be along the UAV's upcoming flight path. In all aspects, NTZ information can be provisioned for a single UE, a group of UEs (e.g., a class of UEs), or a Public Land Mobile Network (PLMN), and the UAV may correspond to a single UE, a group of UEs, or all UEs served by the PLMN. UAS authorized entities can receive transaction reference identifiers (IDs) based on transmissions (e.g., in response to) NTZ information.
[0051] The transaction reference ID can be included in multiple subsequent requests related to the NTZ information. For example, the UAS authorized entity can also transmit an update request to the NEF entity to update the NTZ information at the core network, and the transaction reference ID can be included in the update request. Additionally or alternatively, the UAS authorized entity can also transmit a deletion request to the NEF entity to delete the NTZ information from the core network, and the transaction reference ID can be included in the deletion request.
[0052] In various aspects, the NTZ information provisioning request may also include a request for notification of the delivery results of a subscribed UE policy (which is configured based on NTZ information). Based on (e.g., in response to) the subscription, the UAS authorizing entity may receive notification of the results of UE policy delivery. In an example, the result may indicate successful delivery of the UE policy to the UAV. Alternatively, the result may indicate a failure in the delivery of the UE policy and may also provide the reason for the failure (e.g., the UAV is unreachable).
[0053] In each aspect, when a NEF entity receives an NTZ information configuration request from a UAS authorized entity, the NEF entity can store the NTZ information at a UDR in the core network. In the example, the UDR can provide an API for installing or storing NTZ information at the UDR. In each aspect, when a NEF entity receives an update request from a UAS authorized entity, the NEF entity can update the NTZ information at the UDR. In the example, the UDR can provide an API for modifying the NTZ information stored at the UDR. In each aspect, when a NEF entity receives a deletion request from a UAS authorized entity, the NEF entity can delete the NTZ information from the UDR. In the example, the UDR can provide an API for removing NTZ information from the UDR.
[0054] In various aspects, the NEF entity can subscribe to multiple events of the PCF entity in the core network. For example, the NEF entity can subscribe to the delivery results of a UE policy (configured based on NTZ information and equipped by a UAS authorized entity outside the core network). Based on (e.g., in response to) the NEF entity's subscription, the NEF entity can receive PCF event notification messages from the PCF entity, including an indication of the UE policy delivery results. As mentioned above, an NTZ information equipment request (from the UAS authorized entity) can include a subscription to the UE policy delivery results associated with the NTZ information. Therefore, the NEF entity can also transmit the UE policy delivery results to the UAS authorized entity.
[0055] In various aspects, the PCF entity can subscribe to be notified of data changes associated with NTZ information at the UDR. Therefore, the PCF entity can receive notifications of data changes associated with NTZ information (equipped by the UAS Authorization Entity and stored at the UDR) from the UDR. Upon receiving such a notification, the PCF entity can configure UE policies for the UAV based on the NTZ information. Thus, the PCF entity can configure or generate UE policies for the UAV based on the NTZ information stored at the UDR. The PCF entity can transmit UE policies to the UAV (e.g., via the Access and Mobility Management (AMF) entity of the core network) and receive responses from the corresponding UAV (e.g., via the AMF). If the NEF entity (of the core network) has subscribed to event notifications at the PCF entity, the PCF entity can transmit the UAV's response to the NEF entity.
[0056] According to another aspect of this disclosure, a UE (e.g., a UAV) can receive a UE policy (e.g., an A2X policy) for aircraft communications from a core network, wherein the UE policy may include NTZ information. The UE can receive an updated UE policy from the core network, including (dynamically) updated NTZ information. The UE can transmit a response to the core network regarding the receipt of the updated UE policy. For example, the response may indicate successful reception of the UE policy. In various aspects, the updated NTZ information may include at least one of the following: coordinate information indicating a geographic area, a flag value indicating whether the NTZ applies to a geographic area, frequency information associated with one or more permitted transmission bands, frequency information associated with one or more restricted transmission bands, or information associated with the time period to which the NTZ applies. In various aspects, the UE can avoid performing cell searches or transmissions in a geographic area. In various aspects, the avoidance of performing cell searches or transmissions in a geographic area may also be based on a flag value. In various aspects, as part of the avoidance, the UE can avoid performing cell searches or transmissions in a geographic area during the time period to which the NTZ applies. In all aspects, as part of the avoidance, when the UE is in a geographic area, the UE can avoid performing cell search or transmission in any of the restricted transmission frequency bands. In all aspects, when the UE is in a geographic area, the UE can use frequency bands outside of one or more restricted transmission frequency bands to transmit communication signals. In all aspects, when the UE is in a geographic area, the UE can use frequency bands in one or more permitted transmission frequency bands to transmit communication signals. These and other aspects will be described in more detail later in this document.
[0057] Various aspects of this disclosure can provide several benefits. For example, adding a NEF to provide service operations for external entities (e.g., USS, TPAE) to interface with the core network (e.g., 5GC) to equip, update, and / or delete NTZ information can enable the core network to control and manage the NTZ and band limits for each geographic area to meet spectrum compliance regulations or requirements for aircraft. While this disclosure is discussed in the context of enabling 3GPP 5GC to control and manage the NTZ and band limits for each geographic area used for UAV communications, various aspects of this disclosure are applicable to any suitable type of wireless communication system.
[0058] This disclosure may use the term "serving network device" to refer to a network node or network device (or part thereof) serving a UE. As used herein, the terms "transmit to," "receive from," and "cooperate with" (and variations thereof) include communication that may or may not involve communication through one or more intermediate devices or nodes. The term "acquire" (and variations thereof) includes acquiring in a first instance or re-acquiring after a first instance. The term "connection" may mean a physical connection or a logical connection.
[0059] This disclosure uses 5G NR as an example of a wireless network, and may use smartphones and / or unmanned aerial vehicles as examples of UEs. It is intended and should be understood that such examples are merely illustrative, and this disclosure applies to other wireless networks and user equipment.
[0060] Figure 1 This is a diagram illustrating an example of a wireless network between a network system 100 and a user equipment (UE) 150. The network system 100 may include one or more network nodes 120, one or more servers 110, and / or one or more network devices 130 (e.g., test devices). Network node 120 will be described in more detail below. As used herein, the term "network apparatus" may refer to any component of the network system 100, such as server 110, network node 120, network device 130, any of the foregoing components(s), and / or any other components(s) of the network system 100. Examples of network apparatuses include, but are not limited to, apparatuses for implementing various aspects of 5G NR. This disclosure describes embodiments related to 5G NR and embodiments relating to aspects defined by 3GPP. However, it is contemplated that embodiments related to other wireless network technologies are included within the scope of this disclosure.
[0061] The following description provides further details of examples of network nodes. In a 5G NR network, a gNodeB (also known as a gNB) may include, for example, a node that provides NR user plane and control plane protocol termination toward the UE and is connected to the 5G core (5GC) via an NG interface, such as, according to Section 3.2 of 3GPP TS 38.300 V 16.6.0 (2021-06), which is incorporated herein by reference.
[0062] gNB supports various protocol layers, such as Layer 1 (L1) physical layer, Layer 2 (L2) and Layer 3 (L3).
[0063] NR's Layer 2 (L2) is divided into the following sublayers: Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Service Data Adaptation Protocol (SDAP), among which, for example: The physical layer provides a transmission channel to the MAC sublayer; The MAC sublayer provides logical channels to the RLC sublayer; The RLC sublayer provides RLC channels to the PDCP sublayer; The PDCP sublayer provides radio bearers to the SDAP sublayer; The SDAP sublayer provides QoS flows to 5GC; The control channels include the Broadcast Control Channel (BCCH) and the Physical Control Channel (PCCH).
[0064] Layer 3 (L3) includes, for example, Radio Resource Control (RRC) according to Section 6 of 3GPP TS 38.300 V 16.6.0 (2021-06), which is incorporated herein by reference.
[0065] The gNB Central Unit (gNB-CU) comprises, for example, logical nodes that host, the gNB's RRC, Service Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP) protocols, or the en-gNB's RRC and PDCP protocols, and controls the operation of one or more gNB Distributed Units (gNB-DUs). The gNB-CU terminates at the F1 interface connected to the gNB-DU. The gNB-CU may also be referred to herein as a CU, Central Unit, Centralized Unit, or Control Unit.
[0066] A gNB Distributed Unit (gNB-DU) comprises, for example, a logical node that hosts the RLC, Media Access Control (MAC), and Physical (PHY) layers of a gNB or en-gNB, and its operation is partially controlled by the gNB-CU. One gNB-DU supports one or more cells. A cell is supported by only one gNB-DU. The gNB-DU terminates at the F1 interface connected to the gNB-CU. The gNB-DU may also be referred to herein as a DU or Distributed Unit.
[0067] As used herein, the term "network node" may refer to any one or any combination of gNB, gNB-CU, or gNB-DU. RAN (Radio Access Network) nodes or network nodes (such as, for example, gNB, gNB-CU, or gNB-DU, or portions thereof) may be implemented using means, for example, having at least one processor and / or at least one memory having processor-readable instructions ("program") configured to support and / or be equipped with and / or process CU and / or DU-related functionalities and / or features, and / or at least one protocol (sub)layer (e.g., layer 2 and / or layer 3) of the RAN (Radio Access Network). Different functional divisions between central and distributed units are possible. The following will combine... Figure 11 Examples to describe such devices and components.
[0068] The gNB-CU and gNB-DU portions can be co-located or physically separated, for example. The gNB-DU can even be further divided into, for example, two parts, one including processing equipment and the other including an antenna. The Central Unit (CU) can also be referred to as a Baseband Unit / Radio Equipment Controller / Cloud RAN / Virtual RAN (BBU / REC / C-RAN / V-RAN), Open RAN (O-RAN), or a portion thereof. The Distributed Unit (DU) can also be referred to as a Remote Radio Headend / Remote Radio Unit / Radio Equipment / Radio Unit (RRH / RRU / RE / RU), or a portion thereof. In the various exemplary embodiments of this disclosure, a network node supporting at least one of the Central Unit functions or Layer 3 protocols of the radio access network can be, for example, a gNB-CU. Similarly, a network node supporting at least one of the Distributed Unit functions or Layer 2 protocols of the radio access network can be, for example, a gNB-DU.
[0069] A gNB-CU can support one or more gNB-DUs. A gNB-DU can support one or more cells, and therefore can support serving cells for user equipment (UE), or candidate cells for handover, dual connectivity and / or carrier aggregation and other procedures.
[0070] UE 150 may be or include wireless or mobile devices, devices having a radio interface for interacting with a RAN (Radio Access Network), smartphones, in-vehicle devices, Internet of Things (IoT) devices, machine-to-machine (M2M) devices or UAVs, and other types of user equipment. Such a UE 150 may include: at least one processor; and at least one memory including program code; wherein the at least one memory and the computer program code are configured, together with the at least one processor, to enable the device to perform at least certain operations, such as, for example, an RRC connection to the RAN. Figure 9 Examples of components of the UE are described below. In an embodiment, UE 150 may be configured to generate messages (e.g., including a cell ID) to be transmitted to the RAN via radio (e.g., to reach and communicate with the serving cell). In an embodiment, UE 150 may generate, transmit, and receive RRC messages containing one or more RRC PDUs (Packet Data Units). Those skilled in the art will understand the RRC protocol and other processes that the UE may perform.
[0071] Continue to refer to Figure 1 In an example of a 5G NR network, network system 100 provides one or more cells that define the coverage area of network system 100. As described above, network system 100 may include a gNB of the 5G NR network, or may include any other means configured to control radio communications and manage radio resources within the cells. As used herein, the term "resource" may refer to radio resources such as resource blocks (RBs), physical resource blocks (PRBs), radio frames, subframes, time slots, subbands, frequency regions, subcarriers, beams, etc. In embodiments, network node 120 may be referred to as a base station.
[0072] Figure 1 Examples are provided, and only network system 100 and UE 150 are illustrated. Those skilled in the art will understand that network system 100 includes... Figure 1 Components not shown in the diagram, and it will be understood that other user equipment can communicate with network system 100.
[0073] Figure 2 yes Figure 1 A block diagram of example components of network system 100. A 5G NR network can be described as an example of network system 100, and the aspects described below should also be applicable to other types of network systems. The network system can be configured according to... Figure 1The signals and connections shown operate to enable UE 150 to communicate with network system 100 via RAN 225. Furthermore, the network system can be divided into user plane components and functions and control plane components and functions, as shown and described herein. Unless otherwise stated, the terms “component,” “function,” and “service” are used interchangeably herein and can refer to instructions executed by and implemented by one or more processors.
[0074] The following describes example functionality of the components. This example functionality is merely illustrative, and it should be understood that additional operations and functions can be performed by the components described herein. Furthermore, connections between components can be virtual connections based on service interfaces, allowing any component to communicate with any other component. In this way, any component can act as a service "producer" for any other component acting as a service "consumer," providing services for network functions.
[0075] For example, a control network (CN) 210 is described in the control plane of the network system. CN 210 includes Authentication Server Function (AUSF) 211, AMF 212, and Session Management Function (SMF) 213. CN 210 also includes Network Slice Selection Function (NSSF) 214, NEF 215, Network Repository Function (NRF) 216, and UDM 217, which may include UDR 224.
[0076] The additional components and functions of CN 210 include application function (AF) 218 and PCF 219.
[0077] The user plane includes UE 150, Radio Access Network (RAN) 225, User Plane Function (UPF) 226, and Data Network (DN) 227. RAN 225 may include a combination of Figure 1 The RAN 225 describes one or more components, such as one or more network nodes. However, the RAN 225 may not be limited to such components. The UPF 226 provides connectivity for data transmitted over the RAN 225. For example, the DN 227 identifies services from service providers, internet access, and third-party services.
[0078] AMF 212 handles connectivity and mobility tasks. AUSF 211 receives authentication requests from AMF 212 and interacts with UDM 217 to authenticate and verify network responses to determine successful authentication. SMF 213 performs PDU session management and manages session context with UPF 226.
[0079] NSSF 214 can select a Network Slice Instance (NSI) and determine the allowed Network Slice Selection Auxiliary Information (NSSAI). This selection and determination are used to set up AMF 212 to provide services to UE 150. NEF 215 ensures third-party access to network services to create private network services. NRF 216 acts as a repository for storing network functions to allow functions to register and discover each other.
[0080] UDM 217 generates authentication vectors for use by AUSF 211 and AMF 212 and provides user identity processing. UDM 217 can be connected to UDR 224, which stores data associated with authentication, applications, etc. AF 218 provides application services (e.g., streaming services) to users. PCF 219 provides policy control functions. For example, PCF 219 can assist in network slicing and mobility management, as well as provide QoS and accounting functions. In some instances, UDM 217 and / or UDR 224 may be referred to as network data components.
[0081] like Figure 2 As further shown, the network system also includes a UAS NF 230, which is a NEF that can securely expose the capabilities of CN 210 to third parties and / or non-3GPP entities to provide services to UAVs (e.g., UE 150). Figure 2 In the example shown, UAS NF 230 is outside CN 210. However, in other instances, UAS NF 230 can be part of CN 210. For example, UAS NF 230 can be NEF 215 within CN 210.
[0082] According to various aspects of this disclosure, the UAS NF 230 can communicate with components of the CN 210 (e.g., UDM 217, UDR 224, PCF 219, and AMF 212) to enable third parties and / or non-3GPP entities to equip the CN 210 with NTZ parameters (e.g., NTZ and restricted frequency bands for each geographic area) to configure UE policies (e.g., A2X policies) for the UAV-UE. The mechanisms for enabling the core network to control and manage the NTZ parameters used for UAV communication will be discussed more fully below.
[0083] Figure 2 These are merely examples of components of a network system, and variations are contemplated within the scope of this disclosure. In embodiments, the network system may include... Figure 2 Other components not shown. In embodiments, the network system may not include... Figure 2 Each component is shown. In embodiments, components and connections can utilize [the following]. Figure 2The connections shown are implemented using different connections. These and other embodiments are considered to be within the scope of this disclosure.
[0084] Figure 3 This is a block diagram of an example network system providing services to UAVs according to one aspect of this disclosure. Figure 3 As shown, the network system includes UE 302, 5GS 320, and Evolved Packet System (EPS) 330. UE 302 can be a UAV as described above. UE 302 can perform communication by accessing 5GS 320 and / or EPS 330. In one example, UE 302 can be a 5G UE and can perform communication by accessing 5GS 320. In another example, UE 302 can be an LTE UE and can perform communication by accessing EPS 330. In yet another example, UE 302 can be a dual-connectivity UE and can perform communication by accessing 5GS 320 and EPS 330 (e.g., switching between 5GS 320 and EPS 330).
[0085] The 5GS 320 may include NG RAN 304 and 5GC 310. In one example, NG RAN 304 may correspond to RAN225, and 5GC 310 may include network components, such as those referenced above. Figure 2 The components of UPF 226 and CN 210 are discussed. In the context of 3GPP, NG RAN 304 can communicate with 5GC 310 via the N3 interface.
[0086] EPS 330 may include a (Radio) Access Network ((R)AN) 306 and an Evolved Packet Core (EPC) 312. (R)AN 306 may include a combination of... Figure 1 The network nodes, network components, and / or base stations described. In one example, (R)AN 306 could be EUTRAN. EPC 312 can perform the same operations as referenced above. Figure 2 The CN 210 and UPF 226 discussed are essentially similar in operation. However, the EPC 312 can be compared with... Figure 2 The network system shown has different divisions of core network functions, and may include functions similar to those of other networks. Figure 2 The components shown are different from those in the standard EPC 312. Generally, EPC 312 may include components configured to manage session state, authenticate and track UE 302 across EPS 330, and route data packets via (R)AN 306. In the context of 3GPP, (R)AN 306 can communicate with EPC 312 via the S1 interface.
[0087] like Figure 3As further illustrated, the network system includes a UAS NF 308, which is the NEF associated with the 5GC 310. The UAS NF 308 can communicate with various components of the 5GC 310. In the context of 3GPP, the UAS NF 308 can communicate with the 5GC 310 via interfaces N29, N30, N51, N15, and N36. The UAS NF 308 can perform network functions that expose the services or capabilities of the 5GC 310 to the USS 316 in DN 318. In the context of 3GPP, the UAS NF 308 can communicate with the USS 316 via the N33 interface. In this example, the UAS NF 308 and DN 318 can respectively correspond to... Figure 2 The UAS NF230 and DN 227. USS 316 can support secure airspace use by providing services to UAS operators to meet UTM requirements. Figure 3 In the example shown, UAS NF 308 and USS 316 are outside of 5GS 320. However, in some instances, UAS NF 308 and / or USS 316 may be part of 5GS 320. Additionally or alternatively, UAS NF 308 may operate as a Service Capability Exposure Function (SCEF) to communicate with various components of EPC 312 and perform network functions to expose the services or capabilities of EPC 312 to USS 316.
[0088] like Figure 3 As further shown, TPAE 314 can communicate with 5GS 320 and EPS 330 via DN 318. TPAE 314 can function in UAS management, for example, for UAV traffic control. In the context of 3GPP, TPAE 314 can communicate with 5GC 310 via the N6 interface and with EPC 312 via the SGi interface.
[0089] According to various aspects of this disclosure, UAS NF 308 can provide services to USS 316 and / or TPAE 314 to equip 5GC 310 (or EPC 312) with NTZ information, dynamically update the NTZ information stored at 5GC 310, and / or delete NTZ information from 5GC 310 (or EPC 312). The NTZ information can indicate NTZ and / or frequency band restrictions for each geographic area, for example, to meet certain spectrum compliance requirements. The NTZ information can be configured by 5GC 310 (or EPC 312) to configure UE policies for UE 302 (UAV), enabling UE 302 to avoid transmission in those NTZ and / or restricted frequency bands.
[0090] Figure 3These are merely examples of components of a network system, and variations are contemplated within the scope of this disclosure. In embodiments, the network system may include... Figure 3 Other components not shown. In embodiments, the network system may not include... Figure 3 Each component is shown. In embodiments, components and connections can utilize [the following]. Figure 3 The connections shown are implemented using different connections. These and other embodiments are considered to be within the scope of this disclosure.
[0091] The following describes an example operation for NTZ information provisioning. Figure 4 Example signals and operations for NTZ information are shown. Figure 5 Example signals and operations for updating UE configuration based on NTZ information are shown. Figures 6A to 6C Example NTZ information is shown. Figure 7 Example operation of a network device of a UAS authorized entity such as USS or TPAE is shown. Figure 8 Example operation of a network device of a UAS NF entity is shown. Figure 9 Example operation of a network device of a PCF entity is shown. Figure 10 Example operation of a UE (e.g., UAV-UE) is shown.
[0092] Figure 4 This is a diagram illustrating an example embodiment of operation for equipping NTZ information according to one aspect of this disclosure. It should be understood that the described signals may have associated operations, and the described operations may have associated signals. Therefore, the described signals may also relate to operations, and the described operations may also relate to signals. Additionally, Figure 4 This will describe the signals between various network components and the operations performed by these components, such as... Figure 4 Those shown at the top. Specifically, the components include UE 401, (R)AN 402, AMF 403, PCF 404, UDM 405, UDR 406, NEF 407, and UAS Authorized Entity 408. UE 401 can be a UAV as described above, and can be similar to... Figure 1 UE 150 and / or Figure 3 UE302. AMF 403, PCF 404, UDM 405, and UDR 406 can be similar to Figure 2 CN 210 and / or Figure 3 It is part of the 5GC 310 core network 409. For example, AMF 403, PCF 404, UDM 405, and UDR 406 can be similar to... Figure 2AMF 212, PCF 219, UDM 217, and UDR 224. (R)AN 402 can be similar to... Figure 2 RAN 225 and / or Figure 3 NGRAN 304. NEF 407 can be similar to Figure 2 UAS NF 230 and / or Figure 3 UAS NF 308. UAS authorized entity 408 can be similar to Figure 3 The USS 316 or TPAE 314. Network components are illustrative, and other components are envisioned to involve signals or perform operations. In some examples, each network component in the network assembly may use components with, for example, […]. Figure 11 The apparatus of the components shown is used to implement the operation. One or more of the following operations can be implemented in conjunction with the operations of this disclosure, as referenced above. Figures 1 to 3 Examples of discussion.
[0093] At operation 410, UE 401 can perform a UE registration procedure with core network 409 via (R)AN 402. At operation 412, as part of the UE registration procedure, AMF 403 can interact with PCF 404 to perform policy association. For example, PCF 404 can provide AMF 403 with access and mobility management related policies to trigger policy rules for UE 401. At operation 414, PCF 404 can transmit, and UDR 406 can receive, a subscription to a notification of data changes at UDR 406. In the example, PCF 404 can invoke the Nudr_DM_subscribe service operation provided by UDR 406 as part of the transmission subscription. Those skilled in the art will understand the Nudr_DM_subscribe service operation.
[0094] At operation 416, UAS Authorization Entity 408 can create an AF request to equip the core network 409 with NTZ information. The NTZ information can be configured by the core network 409 to configure UE policies for UAV communication (e.g., at least for UE 401). See below for reference. Figures 6A to 6CMore comprehensively, NTZ information may include indications of the NTZ and / or restricted transmission bands for each geographic area. At operation 418, as part of creating an AF request, UAS Authorization Entity 408 may transmit an NTZ information configuration request, and NEF 407 may receive the NTZ information configuration request. In one example, UAS Authorization Entity 408 may invoke the Nnef_NTZParameter_Create request service operation provided by NEF 407 as part of transmitting the NTZ information configuration request. The Nnef_NTZParameter_Create request service operation may have input parameters, such as, but not limited to, NTZ parameters, an indication of the time period to which the NTZ parameters may be applied or valid (i.e., no transmission restrictions may be time-limited), a target identifier to which the NTZ parameters are to be configured, and / or subscription parameters. In some instances, the indication of the time period may be included as part of the NTZ parameters.
[0095] In various respects, the UAS Authorization Entity 408 may be interested in reports regarding whether UE policies configured with NTZ information have been successfully delivered to the corresponding UE. Therefore, the UAS Authorization Entity 408 may include a request to subscribe to notifications of the results of UE policy delivery (e.g., A2X policy delivery) in the NTZ information provision request.
[0096] In various aspects, the UAS Authorized Entity 408 may configure NTZ information at the individual UE level (e.g., specifically for UE 401), at the UE group level (e.g., for a group of UEs including UE 401), or at the PLMN level (e.g., for all UEs including UE 401 in the PLMN). Accordingly, the NTZ information configuration request may include a target ID identifying the individual UE, UE group, or PLMN for which NTZ information is to be configured. For example, if configuring NTZ information for a single UE, the NTZ information configuration request may include a target UE ID containing a Common Public Subscription Identifier (GPSI). If configuring NTZ information for a group of UEs, the NTZ information configuration request may include a target UE ID containing an external group ID. If configuring NTZ information for a PLMN, the NTZ information configuration request may include the PLMN ID.
[0097] At operation 420, upon receiving an NTZ information configuration request, NEF 407 can interact with UDM 405 to obtain information for performing identifier mapping. In the example, NEF 407 can invoke the Nudm_SDM_Get service operation provided by UDM 405 to request information from UDM 405. Those skilled in the art will understand the Nudm_SDM_Get request service operation. For example, if the NTZ information configuration request includes a target UE ID for a single UE, NEF 407 can map the GPSI in the target ID to a Subscription Permanent Identifier (SUPI) based on the information received from UDM 405. The SUPI is an ID assigned by the 3GPP system. Alternatively, if the NTZ information configuration request includes target UE IDs for a group of UEs, NEF 407 can map the external group ID in the target UE ID to an internal group ID based on the information received from UDM 405. Generally, a UAS-UE (e.g., UE401) can be identified by the UAS Authorized Entity 408 using a Civil Aviation Administration (CAA) level ID (e.g., GPSI, External Group ID) and by the 3GPP system (e.g., Core Network 409) using a 3GPP UAV ID (e.g., SUPI or Internal Group ID). Those skilled in the art will understand the Nudm_SDM_Get service operation.
[0098] At operation 422, NEF 407 can interact with UDM 405 to authorize a service-specific parameter configuration request with UDM 405. More specifically, NEF 407 can interact with UDM 405 to authorize an NTZ information configuration request (received from UAS Authorization Entity 408). In the example, NEF 407 can invoke the Nudm_ServiceSpecificAuthorization_Create service operation provided by UDM 405 as part of the authorization. Those skilled in the art will understand the Nudm_ServiceSpecificAuthorization_Create service operation.
[0099] At operation 424, upon successful authorization of the NTZ information provisioning request, NEF 407 stores the NTZ information at UDR 406. NEF 407 can store the NTZ information in UDR 406 in association with SUPI (when the NTZ information is used for a single UE), External Group ID (when the NTZ information is used for a group of UEs), or PLMN ID (when the NTZ information is used for all UEs in the PLMN). For example, as part of storing the NTZ information, a UDR data element named "Dataset" can be set to "UE Policy Set (UEPolicySet)," and a UDR data element named "Data Subset" can be set to "A2X NTZ Info (A2XNTZ Info)," and UDR 406 can store the NTZ information and assign a transaction reference ID to the storage of the NTZ information. Typically, UDR 406 can use any suitable data structure to store the NTZ information.
[0100] In operation 426, NEF 407 transmits, and UAS Authorization Entity 408 receives a response to the NTZ information provisioning request. In one example, NEF 407 may invoke the Nnef_NTZParameter_Create response service operation to provide a response to UAS Authorization Entity 408. The response may include an assigned transaction reference ID. As will be discussed more fully below, the transaction reference ID may be included in subsequent requests related to the NTZ information. The Nnef_NTZParameter_Create response service operation may have one or more input parameters, including, but not limited to, the transaction reference ID and / or the result of the Nnef_NTZParameter_Create service operation (e.g., success or failure).
[0101] Creating and storing NTZ information at UDR 406 in operation 424 can trigger a data change event at UDR 406. If UE 401 is registered to core network 409, and PCF 404 has subscribed to the data modified in UDR 406 by calling Nudr_DM_Subscribe (USS / TPAE NTZ Parameter Configuration Information, SUPI, dataset set to "UEPolicySet", data subset set to "A2X NTZ Information") in operation 410, then operations 428-434 can be performed. Otherwise, operations 428 to 434 can be omitted.
[0102] In operation 428, UDR 406 transmits data, and PCF receives a notification of a data change occurring at UDR 406 due to NTZ information (provided by UAS Authorized Entity 408). In this example, as part of receiving the notification, PCF 404 may receive a Nudr_DM_Notify notification from UDR 406. Those skilled in the art will understand the Nudr_DM_Notify service operation.
[0103] As described above, in some instances, the UAS Authorization Entity 408 can provide NTZ information to a group of UEs. In such instances, the PCF 404 does not need to subscribe to be notified of NTZ information for each UE (e.g., application-specific information). Instead, the PCF 404 can subscribe to be notified of NTZ information for that group of UEs. For example, when the PCF 404 receives NTZ information for that group of UEs, the PCF 404 can deliver the same NTZ information to each UE in that group.
[0104] At operation 430, upon receiving notification of newly created NTZ information at UDR 406, PCF 404 initiates a UE policy transmission procedure. For example, PCF 404 can configure the NTZ information as part of a UE policy (e.g., an A2X policy), deliver the UE policy to UE 401 via AMF 403, and receive the result of the UE policy delivery via AMF 403. The following will refer to... Figure 5 A more comprehensive discussion of the mechanisms used to execute UE policy delivery.
[0105] If the UAS Authorized Entity 408 has subscribed to notifications regarding UE policy delivery results resulting from NTZ parameter configuration for a single UE (e.g., UE 401), and notifies the PCF 404 of the UE policy delivery results, then the PCF 404 can notify the NEF 407 of the UE delivery results. For example, at operation 432, the PCF 404 transmits and the NEF 407 receives notifications of the delivery results of UE policies configured based on NTZ information. More specifically, the PCF 404 may receive a UE policy container from the AMF 403 (e.g., as part of operation 430) and may transmit the UE policy delivery results included in the UE policy container as the result of the UE policy delivery process to the NEF 407 by sending an Npcf_EventExposure_Notify notification (indicating the result). Those skilled in the art will understand the Npcf_EventExposure_Notify notification.
[0106] If PCF 404 is notified of the UE policy delivery failure from AMF 403 due to UE 401 being unreachable, PCF 404 can determine to retry the UE policy delivery procedure at operation 430 when UE 401 becomes reachable. In this case, PCF 404 can report the temporary state (e.g., UE is temporarily unreachable) to NEF 407 as a result of the procedure by sending an Npcf_EventExposoure_Notify notification (indicating a temporary state).
[0107] If PCF 404 determines at operation 430 that the UE policy delivery process has failed, PCF 404 can notify NEF 407 of the failure and the reason for the failure (e.g., UE unreachable) as a result of the process by sending an Npcf_EventExposure_Notify notification (indicating the failure and the reason for the failure).
[0108] If the UAS Authorization Entity 408 has already subscribed to the results of UE policy delivery, then NEF 407 transmits a notification to the UAS Authorization Entity 408 regarding the results of UE policy delivery received from PCF 404. As shown in the figure, at operation 434, upon receiving the Npcf_EventExposure_Notify notification, NEF 407 transmits an Nnef_ServiceParameter_Notify message to the UAS Authorization Entity 408. In the example, NEF 407 can perform information mapping, for example, mapping the AF (USS / TPAE) transaction internal ID provided in the notification-related ID to the AF (USS / TPAE) transaction ID and / or mapping SUPI to GPSI. In other words, NEF 407 can perform a reverse mapping to map the 3GPP UAV ID to an ID known to the UAS Authorized Entity 408, and the Nnef_ServiceParameter_Notify message can include the GPSI, external ID, or (received as part of the NTZ Information Provisioning Request at Operation 418) PLMN ID, depending on the target recipient of the UE policy delivery, the transaction reference ID (provided at Operation 426), and the result of the UE policy delivery.
[0109] In some instances, UAS Authorization Entity 408 may indicate a resource (e.g., identified by a Uniform Resource Identifier (URI)) in which UAS Authorization Entity 408 may receive notification of subscription. In an example, UAS Authorization Entity 408 may include the indication of a resource as part of a subscription request included in an NTZ Information Provisioning Request transmitted at Operation 418.
[0110] In various aspects, UAS Authorized Entity 408 may optionally update the NTZ information at Core Network 409 based on various conditions or changes. For example, in operation 440, UAS Authorized Entity 408 transmits, and NEF 407 receives, an update request to update the NTZ information at Core Network 409. In the example, UAS Authorized Entity 408 may invoke the Nnef_NTZParameter_Update request service operation and provide the transaction reference ID (at operation 426) to UAS Authorized Entity 408 in the Nnef_NTZParameter_Create response message. The Nnef_NTZParameter_Update request service operation may have input parameters, such as, but not limited to, multiple NTZ update parameters, the transaction reference ID, and / or the result of the Nnef_NTZParameter_Update service operation (e.g., success or failure).
[0111] At operation 442, upon receiving an update request, NEF 407 stores the updated NTZ information at UDR 406. For example, NEF 407 can use SUPI, internal group ID, or PLMN ID as a data key to search the UDR and update the corresponding NTZ information associated with the data key. As part of updating the NTZ information, NEF 407 can interact with UDM 405 to authorize the update request using a mechanism similar to that discussed above with reference to operations 420 and 422.
[0112] At operation 444, based on (e.g., in response to) an update of the NTZ information at UDR 406, UDR 406 transmits and PCF 404 receives a notification of data changes at UDR 406 due to the NTZ information update. In the example, as part of receiving the notification of data changes associated with the NTZ information update, PCF 404 may receive a Nudr_DM_Notify notification from UDR 406. Based on (e.g., in response to) this notification, PCF 404 may trigger a UE policy update procedure, as will be referred to below. Figure 5 Discussed.
[0113] In operation 446, NEF 407 transmits, and UAS Authorization Entity 408 receives a response to the NTZ information update request. In the example, NEF 407 may invoke the Nnef_NTZParameter_Update response service operation to provide a response to UAS Authorization Entity 408. The Nnef_NTZParameter_Update response service operation may have one or more input parameters, such as, but not limited to, the transaction reference ID and update status (e.g., pass or fail).
[0114] In various aspects, UAS Authorized Entity 408 may optionally remove NTZ information at Core Network 409 based on various conditions or changes. For example, in operation 450, UAS Authorized Entity 408 transmits, and NEF 407 receives, a deletion request to remove NTZ information from Core Network 409. In the example, UAS Authorized Entity 408 may invoke the Nnef_NTZParameter_Delete request service operation and provide the transaction reference ID (at operation 426) to UAS Authorized Entity 408 in the Nnef_NTZParameter_Create response message. The Nnef_NTZParameter_Delete request service operation may have one or more input parameters, such as, but not limited to, the transaction reference ID.
[0115] At operation 452, upon receiving a deletion request, NEF 407 deletes the NTZ information from UDR 406. For example, NEF 407 can use SUPI, internal group ID, or PLMN ID as a data key to search the UDR and delete the corresponding NTZ information associated with the data key from UDR 406. As part of deleting the NTZ information, NEF 407 can request UDM 405 to remove the authorization provided by sending the service-specific parameters (NTZ information) of the Nudm_ServiceSpecificAuthoriation_Remove service operation.
[0116] At operation 454, based on (e.g., in response to) the deletion of NTZ information from UDR 406, UDR 406 transmits and PCF 404 receives a notification of data change occurring at UDR 406 due to the deletion of NTZ information. In the example, as part of receiving the notification of data change associated with the deletion of NTZ information, PCF 404 may receive a Nudr_DM_Notify notification from UDR 406. Based on (e.g., in response to) this notification, PCF 404 may trigger a UE policy update procedure, as will be referred to below. Figure 5 Discussed.
[0117] In operation 456, NEF 407 transmits, and UAS Authorization Entity 408 receives a response to the NTZ information deletion request. In the example, NEF 407 may invoke the Nnef_NTZParameter_Delete response service operation to provide a response to UAS Authorization Entity 408. The Nnef_NTZParameter_Delete response service operation may have one or more input parameters, such as, but not limited to, the transaction reference ID and / or deletion status (e.g., successful or failed).

[0119] Figure 5 This is a diagram illustrating an example embodiment of an operation for updating a UE configuration based on new NTZ information, according to one aspect of this disclosure. It should be understood that the described signals may have associated operations, and the described operations may have associated signals. Therefore, the described signals may also relate to operations, and the described operations may also relate to signals. Additionally, Figure 5 This will describe the signals between various network components and the operations performed by these components, such as... Figure 5 Those shown at the top. Specifically, the components include UE 401, (R)AN 402, AMF 403, and PCF 404. The network components are illustrative, and other components are envisioned to involve signaling or executable operations. One or more of the following operations may be implemented in conjunction with the operations of this disclosure, as referenced above. Figure 4 Examples discussed. For instance, UE 401, (R)AN 402, AMF 403, and PCF404 can be executed. Figure 5 The operation shown is as Figure 4 This is part of operation 430.
[0120] PCF 404 can typically provide policy control functions to (or register with) multiple UEs associated with (or registered with) core network 409. As an example, PCF 404 can determine policy rules for UE 401. PCF 404 can divide the UE policy for UE 401 into one or more policy segments (or policy containers), each policy segment including one or more policy rules for UE 401. PCF 404 can assign a Policy Segment Identifier (PSI) to each policy segment. PCF 404 can deliver UE policy information to UE 401, whereby the UE policy information may include the content of each policy segment (e.g., (multiple) rules) and the corresponding PSI. PCF 404 can maintain an up-to-date list of PSIs delivered to UE 401 and can update the up-to-date list of PSIs in UDR 406, for example, by invoking the Nudr_DM_Update(SUPI, Policy Data, Policy Set Entry, Updated PSI Data) service operation. When a UE policy is received at UE 401, UE 401 may store multiple PSIs and their corresponding content at UE 401. Therefore, the multiple PSIs and their corresponding content at UE 401 are synchronized with the multiple PSIs and their corresponding content known at PCF 404 and stored at UDR 406. However, PCF 404 may subsequently update the UE policy for UE 401 based on changes in conditions and / or requirements (e.g., when new NTZ information becomes available).
[0121] In operation 510, due to the new NTZ information available at core network 409 (or more specifically, UDR 406), PCF 404 decides to update the A2X policy (e.g., UE policy). The new NTZ information can be provided by the UAS Authorized Entity 408 outside core network 409, as referenced above. Figure 4 The PCF 404 can determine the A2X policy update based on various triggering conditions. In one example, the triggering condition could be when UE 401 performs initial registration with core network 409. In another example, core network 409 could be part of 5GS (e.g., 5GS 320), and the triggering condition could be when UE 401 moves from EPS (e.g., EPS 330) to 5GS. In yet another example, the triggering condition could be based on notification of data changes associated with NTZ information stored at UDR 406.
[0122] In the case of initial registration or 5GS registration (due to UE 401 moving from EPS to 5GS), PCF 404 can compare the list of policy PSIs included in the A2X policy information provided in the Npcf_UEPolicyControl_Create request (received from AMF 403) with the list of PSIs stored at UDR 406. For example, as part of registration, UE 401 may transmit the list of PSIs stored at UE 401 via AMF 403, and when the Npcf_UEPolicyControl_Create request is transmitted to PCF 404, AMF 403 may include the list of PSIs stored at UE 401 in the A2X policy information. In some instances, there may be no PSIs stored at UE 401, and therefore the A2X policy information in the Npcf_UEPolicyControl_Create request may not include any PSIs (e.g., an empty PSI list). In the example, new NTZ information may be stored at UDR 406 in association with new PSIs. Therefore, PCF 404 can determine updated A2X policy information for UE 401 based on the new PSI (for NTZ information). PCF 404 can deliver A2X policy information, including NTZ information and the corresponding PSI, to UE 401 via AMF 403. In the example, AMF 403 can use downlink (DL) non-access stratum (NAS) transmission messages to provide updated A2X policy information to UE 401.
[0123] In the event of a network-triggered UE policy update (e.g., due to a change in UE location), PCF 404 can examine the latest PSI list delivered to UE 401 and stored at UDR 406 to determine which A2X policies must be transmitted to UE 401. For example, based on UE 401's new location, PCF 404 can determine that new PSIs for policy segments including NTZ information will be delivered to UE 401.
[0124] At operation 512, if PCF 404 has not yet subscribed to the response from AMF 403 to UE 401 regarding updates to UE policy information, then PCF 404 subscribes to AMF 403 to be notified of the response from AMF 403 to updates to UE policy information.
[0125] At operation 514, PCF 404 transmits and AMF 403 receives UE policy information including NTZ information. In the example, PCF 404 may invoke the Namf_Communication_N1N2MessageTransfer service operation provided by AMF 403 to initiate the delivery of UE policy information to UE 401. For example, the Namf_Communication_N1N2MessageTransfer message may include a SUPI (identifying UE 401) and a UE policy container (or more specifically, an A2X policy container) including NTZ information.
[0126] At operation 516, network-triggered service requests can be executed by AMF 403. For example, if UE 401 is registered and reachable by AMF 403, AMF 403 can transparently transmit the A2X policy container to UE 401 via (R)AN 402 through the registered access. However, if AMF 403 is not reachable from UE 401, AMF 403 can initiate a network-triggered service request to make UE 401 reachable.
[0127] At operation 518, if UE 401 accesses a connection via 3GPP using Connection Management (CM), AMF 403 can transparently deliver or transmit the A2X policy container (including UE policy information such as NTZ information) received from PCF 404 to UE 401. Upon receiving the A2X policy container, UE 401 updates the A2X policy and corresponding NTZ information provided by PCF 404. See below for reference. Figures 6A to 6C More comprehensively, UE 401 may comply with NTZ information (e.g., (multiple) configured NTZ and / or (multiple) band limits) and adjust the behavior of UE 401 accordingly.
[0128] At operation 520, UE 401 transmits the result of A2X policy delivery, and AMF 403 receives the result of A2X policy delivery. For example, UE 401 may transmit an A2X policy container including the delivery result to AMF 403.
[0129] At operation 522, AMF 403 uses the Namf_Communication_N1MessageNotify notification to forward the response of UE 401 to PCF 404.
[0130] Subsequently, PCF 404 can maintain the latest PSI list delivered to UE 401 and update the latest PSI list in UDR 406 by calling the Nudr_DM_Update(SUPI, policy data, policy set entry, updated PSI data) service operation.
[0131] Figure 5 These are merely examples of signals and operations, and variations are considered to be within the scope of this disclosure. In embodiments, signals and operations may include... Figure 5 Other signals and operations not shown. In embodiments, signals and operations may not include... Figure 5 Each signal and operation is shown. In an embodiment, the signals and operations can utilize [the following]. Figure 5 The connections shown are implemented using different connections. These and other embodiments are considered to be within the scope of this disclosure.
[0132] Figures 6A to 6C The illustration depicts an example NTZ information for UAV communication according to one aspect of this disclosure. (Combined with...) Figure 4 discuss Figures 6A to 6C .like Figure 6A As shown, NTZ information 600 may include NTZ parameter fields 610, 620, and 630. In various aspects, NTZ information 600 may correspond to... Figure 4 Operation 418 is provided by NTZ information from UAS authorized entity 408.
[0133] NTZ parameter field 610 is related to geographic area information. For example, NTZ parameter field 610 can instruct UE 401 to use a region not covered by RAN (e.g., EUTRA (such as...)). Figure 3 (R)AN 306) or NG RAN (such as Figure 3 The geographic area served by NG RAN 304. Figure 6B As shown, the NTZ parameter field 610 can include a list of coordinates 612, each coordinate including indications of longitude, latitude, and altitude. The coordinate information can indicate the boundaries of a geographic area or airspace.
[0134] NTZ Parameter Field 620 relates to radio parameters. For example, NTZ Parameter Field 620 can indicate radio parameters such as which frequency bands(s)(s) are permitted to transmit by UAV-UE (e.g., UE 150, 302, and / or 401) and / or which frequency bands(s) are restricted from transmission by UAV-UE (e.g., UE 150, 302, and / or 401) in a specific geographic area specified by NTZ Parameter Field 620. Figure 6BAs shown, the NTZ parameter field 620 may include a flag value 622 (or parameter 622) indicating whether the NTZ is applicable to a specific geographic area (e.g., the geographic area indicated by the NTZ parameter field 610). For example, the flag value 622 may be set to a value of 1 to indicate that the NTZ is applicable to the geographic area, or set to a value of 0 to indicate that the NTZ is not applicable to the geographic area, and vice versa. Additionally or alternatively, the NTZ parameter field 620 may include a list 624 (or parameters 624) of the transmission bands(s) that the UAV-UE is allowed or not allowed to perform transmissions. In other words, the NTZ parameter field 620 may include frequency information for one or more allowed transmission bands and / or one or more restricted transmission bands. In some instances, the NTZ parameter field 620 may be optional.
[0135] NTZ parameter field 630 may include information associated with the time period to which the NTZ applies for a specific geographic area (e.g., the geographic area indicated by NTZ parameter field 610). In an example, NTZ parameter field 630 may include an indication of the start and / or end times (e.g., time of day) for which the NTZ applies in that geographic area. As an example, NTZ parameter field 630 may indicate 10:00–11:00. As another example, NTZ parameter field 630 may indicate 10:00–11:00 and 00:00–06:00. Typically, NTZ parameter field 630 may indicate any suitable number of time periods to which the NTZ applies (e.g., 1, 2, 3, 4, or more) and / or use any suitable time format. In some instances, NTZ parameter field 630 may be optional.
[0136] In various aspects, UE 401 can receive NTZ information 600 and adapt its behavior based on NTZ information 600. To this end, UE 401 can determine its current location, for example, based on a Global Navigation Satellite System (GNSS) or Global Positioning System (GPS) receiver at UE 401. UE 401 can check whether it is within or outside the geographic area indicated by NTZ information 600, for example, based on a comparison of UE 401's location with a list of coordinates 612 or based on the radial distance between UE 401's location and a single coordinate in coordinates 612. If UE 401 is within the NTZ geographic area, UE 401 can check whether all transmissions are prohibited (i.e., no permitted transmission bands) or whether some bands are restricted. When UE 401 is within the geographic area, UE 401 can perform or not perform transmission and / or cell search based on NTZ information 600.
[0137] In various aspects, NTZ information 600 may include at least NTZ parameter field 610 (indicating a geographic area), and may optionally include one or more parameters from NTZ parameter fields 620 and / or 630. In the first example, NTZ information 600 may include an indication of a geographic area (e.g., a list of coordinates 612), and an exclusion flag value 622 and a list 624 of allowed or disallowed frequency bands(s). Such NTZ information 600 may indicate a general restriction on transmission (i.e., no allowed transmission frequency bands). Therefore, UE 401 may (completely) avoid performing cell search or transmission in the geographic area. In other geographic areas (outside the geographic area indicated by NTZ parameter field 610), UE 401 may perform transmission based on the frequency band information provided to UE 401 (e.g., in an A2X policy). If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), UE 401 may (completely) avoid performing cell search or transmission in that geographic area during the indicated time period.
[0138] In the second example, NTZ information 600 may include an indication of a geographic area (e.g., a list of coordinates 612) and a flag value 622, and a list 624 of excluded or disallowed frequency bands(s). If flag value 622 indicates that NTZ applies, UE 401 may (completely) avoid performing cell searches or transmissions in the geographic area. If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), UE 401 may (completely) avoid performing cell searches or transmissions in the geographic area during the indicated time period. If flag value 622 indicates that NTZ does not apply, UE 401 may not restrict its transmissions in the geographic area.
[0139] In the third example, NTZ information 600 may include an indication of a geographic area (e.g., a list of coordinates 612) and a parameter 624 indicating restricted (disallowed) transmission bands(s), and an exclusion flag value 622. Based on such NTZ information 600, when UE 401 is in the geographic area, UE 401 can avoid performing cell search or transmission in any of the restricted transmission bands(s). Additionally or alternatively, UE 401 may use frequency bands outside the restricted transmission bands(s) to transmit communication signals. If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), UE 401 may avoid performing cell search or transmission in any of the restricted transmission bands(s) and / or use frequency bands outside the restricted transmission bands(s) to transmit communication signals during the indicated time period.
[0140] In the fourth example, NTZ information 600 may include an indication of a geographic area (e.g., a list of coordinates 612) and a parameter 624 indicating permitted transmission bands(s), and an exclusion flag value 622. Based on such NTZ information 600, UE 401 can transmit communication signals using frequency bands in the permitted transmission bands(s). Alternatively or additionally, UE 401 can avoid performing cell search or transmission in any band outside the permitted transmission bands. If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), UE 401 can use frequency bands in the permitted transmission bands to transmit communication signals and / or avoid performing cell search or transmission in any band outside the permitted transmission bands during the indicated time period.
[0141] In the fifth example, NTZ information 600 may include an indication of a geographic area (e.g., a list of coordinates 612), a flag value 622, and a list 624 of permitted or prohibited frequency bands. If flag value 622 indicates that NTZ applies, then the frequency band(s) in parameter 624 are restricted transmission band(s) (not permitted for transmission). Therefore, when UE 401 is in a geographic area, UE 401 can avoid performing cell search, lateral link discovery / advertising, or transmission in any of the restricted transmission bands(s), where the avoidance is based on flag value 622 indicating that NTZ applies. Additionally or alternatively, UE 401 may use frequency bands outside the restricted transmission bands(s) to transmit communication signals. If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), then UE 401 may avoid performing cell search or transmission in any of the restricted transmission bands(s) and / or use frequency bands outside the restricted transmission bands(s) to transmit communication signals during the indicated time period. However, if flag value 622 indicates that NTZ is not applicable, then the frequency band(s) in parameter 624 are the permitted transmission frequency band(s). Therefore, UE 401 can use frequency band(s) from the permitted transmission frequency band(s) to transmit communication signals. Alternatively or additionally, UE 401 can avoid performing cell search or transmission in any frequency band(s) outside the permitted transmission frequency band(s). If NTZ information 600 also includes timing information (e.g., NTZ parameter field 630), then UE 401 can use frequency band(s) from the permitted transmission frequency band(s) to transmit communication signals and / or avoid performing cell search or transmission in any frequency band(s) outside the permitted transmission frequency band(s) during the indicated time period.
[0142] In various aspects, the UAS Authorized Entity 408 may be unaware of the frequency bands used (or permitted) by the Public Land Mobile Network (PLMN) serving UE 401. For example, the PLMN may configure UE 401 to transmit using certain frequency bands. If parameter 624 indicates permitted transmission frequency bands (e.g., in the fourth and fifth examples described above, where flag value 622 indicates that NTZ is not applicable), then the core network 409, the corresponding RAN, and UE 401 may have to restrict UE 401's transmissions to a portion of the permitted transmission frequency bands indicated by parameter 624 and a portion of the frequency bands configured by the PLMN.
[0143] In other words, NTZ information 600 can coordinate information indicating a geographic area (e.g., coordinates 612) and may optionally include one or more of the following: a flag value indicating whether NTZ is applicable to the geographic area (e.g., flag value 622), information associated with one or more permitted transmission bands (e.g., parameters 624), information associated with one or more restricted transmission bands (e.g., parameters 624), or information associated with the time period to which NTZ applies (e.g., timing information in NTZ parameter field 630).
[0144] Figures 6A to 6C The NTZ information 600 is merely illustrative, and variations are considered to be within the scope of this disclosure. Typically, the parameters in the NTZ information 600 can be arranged in any suitable order. Furthermore, in some instances, the NTZ information 600 may indicate multiple geographic areas (e.g., 2, 3, 4 or more) and include radio parameter(s) and / or timing validity information for each geographic area(s).
[0145] Figure 7 This is a flowchart illustrating an example operation of a network device equipped with NTZ information according to one aspect of this disclosure. In one aspect, the network device may be a UAS authorized entity (such as those mentioned above). Figure 4 The device or network node discussed is the UAS Authorized Entity 408. In some examples, the network device can use a device with, for example, Figure 11 The device shown implements the operation using the components. Figure 7 The operations can include those described in the reference above. Figures 1 to 5 A similar mechanism is discussed. As shown in the figure, Figure 7 It includes several enumerated steps, but Figure 7 The aspects of the operation may include additional steps before, after, and between the listed steps. Within each aspect, one or more of the listed steps may be omitted or performed in a different order.
[0146] In box 702, the network device of the UAS Authorizing Entity transmits an NTZ Configuration Request to the core network, wherein the NTZ information is configured by the core network to configure UE policies for UAV. In some instances, the UAS Authorizing Entity may correspond to UAS Authorizing Entity 408, which may be, for example... Figure 3 USS 316 or such Figure 3 The TPAE 314. In some instances, the core network can correspond to... Figure 2 CN 210, Figure 3 5GC 310 and / or Figure 4 The core network is 409. In some instances, the UAV can correspond to... Figure 1 UE 150 Figure 3 UE 302 and / or Figure 4 UE 401. In one example, the network device can transmit an NTZ information provisioning request by invoking the Nnef_NTZParameter_Create request service operation provided by the NEF entity of the core network (e.g., UAS NF 230, UAS NF 308 and / or NEF 407).
[0147] In all aspects, NTZ information includes at least one of the following: coordinate information indicating a geographic area, a flag value indicating whether NTZ applies to a geographic area, information associated with one or more permitted transmission bands, information associated with one or more restricted transmission bands, or information associated with the time period to which NTZ applies, for example, as referenced above. Figures 6A to 6C The discussion focuses on the following: In each aspect, the UAS authorizing entity can equip an individual UE (e.g., a specific UAV-UE), a group of UEs (e.g., a class of UAV-UEs), or a PLMN with NTZ information, and a UAV can correspond to a single UE served by the PLMN, the group of UEs, or all UEs (UAV-UEs). For example, if NTZ information is equipped for a group of UEs, then the UAV is one of the UEs in that group. If NTZ information is equipped for the PLMN, then the UAV is one of the UEs served by the PLMN.
[0148] At box 704, the network device receives a transaction reference ID based on (e.g., in response to) a transmission NTZ information configuration request. In the example, the network device may receive the transaction reference ID via an Nnef_NTZParameter_Create response service operation provided by a NEF entity in the core network.
[0149] In various aspects, the NTZ information provision request at box 702 also includes a request for notification of the result of delivery of a UE policy configured based on the NTZ information for subscription, and the network device also receives notification of the result of UE policy delivery based on (e.g., in response to) the subscription. In the example, the network device may receive the notification from the NEF entity via an Nnef_ServiceParameter_Notify message.
[0150] In various aspects, the network device also transmits update requests to update NTZ information at the core network, where the update request includes the transaction reference ID obtained at box 704. In the example, the network device may transmit the update request via the Nnef_NTZParameter_Update request service operation provided by the NEF entity.
[0151] In various aspects, the network device also transmits a delete request over the network to remove NTZ information from the core network, wherein the delete request includes the transaction reference ID obtained at box 704. In the example, the network device may transmit the delete request via the Nnef_NTZParameter_Delete request service operation provided by the NEF entity.
[0152] Figure 8 This is a flowchart illustrating one aspect of the operation of a network device equipped with NTZ information, according to an illustrative aspect of this disclosure. In one aspect, the network device may be a NEF entity (such as those described above, referred to separately). Figure 2 , Figure 3 and / or Figure 4 The discussion focuses on devices or network nodes (UAS NF 230, UAS NF 308, and / or NEF 407). In some examples, network devices can use devices with features such as... Figure 11 The device shown implements the operation using the components. Figure 8 The operations can include those described in the reference above. Figures 1 to 5 A similar mechanism is discussed. As shown in the figure, Figure 8 It includes several enumerated steps, but Figure 8 The aspects of the operation may include additional steps before, after, and between the listed steps. Within each aspect, one or more of the listed steps may be omitted or performed in a different order.
[0153] In box 802, the network device of the NEF entity associated with the core network receives an NTZ information provisioning request from the UAS Authorized Entity to provision NTZ information to the core network, wherein the NTZ information is configured by the core network to configure UE policies for UAV. In some instances, the NEF entity may correspond to Figure 2 UAS NF 230, Figure 3UAS NF 308 and / or Figure 4 The NEF 407. In some instances, the core network can correspond to... Figure 2 CN 210, Figure 3 5GC 310 and / or Figure 4 The core network is 409. In some instances, the UAS Authorization Entity can correspond to UAS Authorization Entity 408, which can be, for example... Figure 3 USS 316 or such Figure 3 The TPAE of 314. In some instances, the UAV may correspond to... Figure 1 UE 150 Figure 3 UE302 and / or Figure 4 UE 401. In the example, the network device can receive an NTZ information configuration request via the Nnef_NTZParameter_Create request service operation.
[0154] In all aspects, NTZ information includes at least one of the following: coordinate information indicating a geographic area, a flag value indicating whether NTZ applies to a geographic area, information associated with one or more permitted transmission bands, information associated with one or more restricted transmission bands, or information associated with the time period to which NTZ applies, for example, as referenced above. Figures 6A to 6C The discussion focuses on the following: In various aspects, NTZ information can be provided for a single UE (e.g., a specific UAV-UE), a group of UEs (e.g., a class of UAV-UEs), or a PLMN, and a UAV can correspond to a single UE served by the PLMN, the group of UEs, or all UEs (UAV-UEs). For example, if NTZ information is provided for a group of UEs, then the UAV is one of the UEs in that group. If NTZ information is provided for the PLMN, then the UAV is one of the UEs served by the PLMN.
[0155] At box 804, the network device transmits a transaction reference ID to the UAS authorizing entity based on (for example, in response to) receiving an NTZ information provisioning request. In the example, the network device may transmit the transaction reference ID via the Nnef_NTZParameter_Create response service operation.
