Description

[001] The modalities of the present disclosure relate to the field of communication technology and, in particular, to a method of communication, an apparatus, a device, a chip, a storage medium, a computer program product and a computer program. BACKGROUND

[002] Integrated communication and detection refers to a new information processing technology that allows for coordinated performance of detection and communication functions based on the sharing of hardware and software resources or information sharing. This technology can effectively increase system spectrum efficiency, hardware efficiency, and information processing efficiency. Considering that wireless electromagnetic wave signals used in cellular networks can detect surrounding information from devices (e.g., terminal devices), integrated communication and detection can be applied to future cellular networks.

[003] In a related technique, a terminal device uses a radio access network (RAN) device where the terminal device is currently docked, typically as an auxiliary RAN to aid in detection. However, in practical applications, for specific detection tasks, the RAN where the terminal device is currently docked may not be a better auxiliary RAN, or the terminal device may require other auxiliary RANs in addition to the RAN where the terminal device is docked.

[0060] 2. RAN, which can provide the function of accessing a communication network for authorized users in a specific area. Specifically, the RAN can include a wireless network device in a 3GPP (3GP) network and can also include an access point in a non-3GPP network. For convenience in the description below, the RAN will be referred to as a RAN device.

[0061] The RAN device can be responsible for functions such as radio resource management, quality of service (QoS) management, data compression, and encryption on one side of the air interface. The RAN device provides access services to the terminal device, and then the forwarding of control signals and user data between the terminal device and a core network is completed.

[0065] 5. UPF, which is mainly used to receive and forward user plan data. For example, UPF can receive user plan data from a DN and send it. Petition 870250083541, dated 09 / 17 / 2025, page 22 / 313 16 / 126 user plan data is sent to the terminal device via an access network (AN) device. The UPF can also receive user plan data from the terminal device via the AN device and forward it to the DN.

AF, which is primarily used to provide services to 3GPP networks, such as interacting with PCF for policy control, etc. AF can be a third-party functional entity or an application service deployed by operators, such as IP Multimedia Subsystem (IMS) voice call services. In the present disclosure, a multi-access edge computing (MEC) platform or an application server can communicate with a 5G core network as AF.

[0068] 8. UDM, which is mainly used to control user data, for example, managing signature information, including acquiring signature information from a network element of the Unified Data Repository (UDR) and providing the same to other network elements (such as AMF); generating a 3GPP authentication credential for the UE; registering and maintaining a network element where the terminal device is currently stationed, for example, an AMF (i.e., Service AMF) where the UE is currently stationed.

[0069] 9. DN, which is an operator network used Petition 870250083541, dated 09 / 17 / 2025, page 23 / 313 17 / 126 primarily to provide data services to the EU. For example, an Internet, a third-party service network, an IP Multimedia Services (IMS) network, and the like.

[0070] 10. AUSF, which is mainly used for user authentication, etc.

[0071] 11. NSSF, which is mainly used to determine a network slice instance that the UE is allowed to access based on slice selection measurement information, UE subscription information, and the like.

[0072] In the network architecture illustrated in Figure 1, network elements can communicate with each other through interfaces illustrated in Figure 1. As illustrated in Figure 1, UE can be connected to an AMF network element through port N1, and a RAN device can be connected to the AMF network element through port N2. UE is connected to the RAN device through port Uu. N3 is a connection between the RAN device and a UPF network element.

[0073] It should be noted that Figure 1 is only an exemplary network architecture. The network architectures applicable to the embodiments of the present disclosure are not limited to this example. Any network architecture with the ability to perform the functions of the network elements above is applicable to the embodiments of the present disclosure.

[0074] It should also be noted that the embodiments of the present disclosure also refer to a Network Exposure Function (NEF) network element, a Detection Function (SF) network element, a UDR and a Network Repository Function (NRF) network element, and the main functions of each network element are described as follows.

[0075] NEF, which can also be called network exposure device, network exposure function entity, network capacity exposure function entity, network capacity exposure function device, network capacity exposure function element, network capacity exposure device, etc. The NEF is mainly used to support the exposure of resources and events, such as the secure exposure of services and resources provided by 3GPP network functions to the outside world.

[0076] SF, which is mainly used for the control of detection functions, calculation and display of detection information.

[0077] UDR, which is mainly used for managing user identification, signature data Petition 870250083541, dated 09 / 17 / 2025, page 25 / 313 19 / 126 and authentication data, as well as the management of user service network element registration (e.g., Service AMF).

[0078] NRF, which can also be called a network storage device, network storage function element, and network storage function entity, is primarily used to support service discovery functions. The NRF receives a network element discovery request from a network element function or a Service Communication Proxy (SCP) and can provide feedback for network element discovery request information. At the same time, the NRF is also responsible for maintaining information on the available network functions and services that each supports. NRF can also be understood as the network storage device. A discovery process is a process in which a network element function (NF) requests the addressing of a specific NF or a specific service through the NRF, and the NRF provides an IP address or a Fully Accessible Domain Name. A Qualified Domain Name (FQDN) or a Unified Resource Identifier (URI) of a corresponding NF instance or NF service instance. Additionally, the NRF can also enable the discovery process between PLMNs by providing a network identity (such as a PLMN ID). To achieve discovery of network element function addresses, each network element must be registered with the NRF, and some network element functions can be registered with the NRF when they are first executed. The network storage function device can be a primary network device. Petition 870250083541, dated 09 / 17 / 2025, page 26 / 313 20 / 126

[0079] It should be understood that the above network elements or functions may be network elements on a hardware device, software functions running on dedicated hardware, or virtualization functions instantiated on a platform (e.g., a cloud platform). Optionally, the above network elements or functions may be implemented by a single device, jointly by multiple devices, or as a functional module within a device, which is not limited by the embodiments of this disclosure.

[0080] Furthermore, the network element may be referred to as an entity, device, apparatus, module, or the like, which is not particularly limited in the present disclosure. Additionally, in order to facilitate understanding and explanation, the description of network element is omitted in some descriptions below, for example, the AMF network element is simply referred to as AMF, and in this case, AMF should be understood as the AMF network element or the AMF entity, and the description of the same or similar cases will be omitted below.

[0081] In the embodiments of the present disclosure, integrated communication and detection refer to a new information processing technology that enables a coordinated performance of detection and communication functions based on the sharing of hardware and software resources or information sharing. This technology can increase system spectrum efficiency, hardware efficiency, and information processing efficiency effectively.

[0082] Current cellular networks (such as 5G networks) Petition 870250083541, dated 09 / 17 / 2025, page 27 / 313 21 / 126 waves are frequently used for wireless communication and data transmission. However, in fact, the wireless electromagnetic wave signals used by cellular networks are not only used for wireless communication and data transmission, but also have the ability to perform sensing tasks, which can be used to detect surrounding information from the device (such as a terminal device). The sensing task may include at least one of:

[0083] a user execution action;

[0084] respiratory monitoring;

[0085] a speed of movement of the terminal device;

[0086] environmental imaging; and

[0087] monitoring of weather conditions.

[0088] Therefore, future cellular networks can be used not only for wireless communication and data transmission, but also to perform the task of detection. That is, integrated communication and detection can be applied to future cellular networks.

[0089] In the related technique, the detection scenarios / methods when performing the detection task include the following:

[0090] (1) base station echo detection link (i.e., single gNB detection): the base station sends detection signals and receives echo signals;

[0091] (2) detection link between base stations (i.e., gNB-gNB detection): base station B receives detection signals sent by base station A;

[0092] (3) air interface uplink detection link (i.e., uplink detection) Petition 870250083541, dated 09 / 17 / 2025, p. 28 / 313 22 / 126 ascending UE-gNB): the base station receives the detection signals sent by the terminal;

[0093] (4) air interface downlink detection (i.e., UE-gNB downlink detection): the terminal receives the detection signals sent by the base station;

[0094] (5) Terminal echo detection link (i.e., single UE detection): the terminal sends detection signals and receives echo signals;

[0095] (6) detection link between terminals (i.e., UE-UE detection): terminal B receives the detection signals sent by terminal A.

[0096] In an early stage of integrated Beyond 5G (B5G) communication and detection, on the one hand, existing air interface signals can be reused as much as possible to perform the detection task without introducing excessive enhancements to the air interface. On the other hand, given the complexity of full duplex implementation, collaborative detection between UEs and / or base stations is a prioritized direction.

[0097] Figure 2 illustrates a first detailed flow diagram of a method for UE detection, and the detection function can be supported on a 3GPP network by adding a SF and a corresponding flow. As illustrated in Figure 2, when a consumer NF sends a detection request for a target UE to a core network of the 3GPP network, the core network can select, via the SF or an AMF, a RAN (i.e., Service RAN) where the target UE is currently stationed or the target UE and obtain a result of the detection task completion through communication between Petition 870250083541, dated 09 / 17 / 2025, page 29 / 313 23 / 126 Service RAN and target UE. The detailed flow may include the following operations.

[0098] In S201, the consumer invoice sends the third-party request information to the SF.

[0099] Third-party request information can be used to request the EU to obtain the result of performing the detection task.

[00100] It should be noted that the consumer NF may be at least one of AF, NEF and UE, or may be other network elements or devices, which is not limited by the purposes of this disclosure.

[00101] For example, the consumer invoice can be the NEF, and the NEF can send third-party request information to the SF.

[00102] For example, the consumer invoice can be the NEF and the AF. The AF can send third-party request information to the NEF, and the NEF can send third-party request information to the SF.

[00103] In some modalities, the third-party request information may include UE attribute information.

[00104] Additionally, EU attribute information may include EU identification information and / or address information.

[00105] It should be noted that EU identification information may include at least one of the following:

[00106] Permanent Signature Identifier Information (SUPI);

[00107] Hidden Signature Identifier Information (SUCI); and Petition 870250083541, dated 09 / 17 / 2025, page 30 / 313 24 / 126

[00108] Generic Public Signature Identifier (GPSI) Information.

[00109] It should also be noted that EU address information may include IP (Internet Protocol) address information and / or MAC (Media Access Control) address information.

[00110] In some applications, the third-party application information may include at least one of the following:

[00111] detection task identification information;

[00112] quality information needed to perform the detection task; and

[00113] a detection scenario / method when performing the detection task.

[00114] The quality information required to perform the detection task may be precision information necessary to perform the detection task, or it may be other information, which is not limited by the embodiments of the present disclosure.

[00115] The detection scenario / method when performing the detection task can be one of the following: single gNB detection, gNB-gNB detection, UE-gNB uplink detection, UE-gNB downlink detection, single UE detection, and UE-UE detection.

[00116] In the embodiments of the present disclosure, the detection scenario / method when performing the detection task mainly includes UEgNB uplink detection or UE-gNB downlink detection.

[00117] In S202, SF determines the UE attribute information. Petition 870250083541, dated 09 / 17 / 2025, page 31 / 313 25 / 126

[00118] It should be noted that the SF or other network elements (such as the NEF, etc.) can map the UE identification information, and the identification information is converted into SUPI information, SUCI information, GPSI information, etc., which can be used directly for internal querying within the main network.

[00119] By way of example, the SF can map UE identification information by consulting other network elements (e.g., AMF / UDR / UDM) or by consulting local information, thus obtaining SUPI information, SUCI information, GPSI information and the like for internal consultation within the main network.

[00120] Note that the UE above is the target UE. After determining the UE attribute information, the SF can determine the Service RAN based on the UE attribute information. Alternatively, the SF can first determine the Service RAN attribute information and then determine the UE based on the Service RAN attribute information.

[00121] It should also be noted that, in the embodiments of the present disclosure, the target UE may be determined by SF, or may be determined by other network elements (such as the UE Service AMF or UDM, etc.), which is not limited by the embodiment of the present disclosure.

[00122] In S203, SF sends the fifth request information to AMF.

[00123] The fifth request information can be used to request the result of performing the detection task. Petition 870250083541, dated 09 / 17 / 2025, page 32 / 313 26 / 126

[00124] It should be noted that the fifth request information may be referred to as a detection instruction.

[00125] In some modalities, the fifth request information may include EU attribute information.

[00126] Additionally, EU attribute information may include EU identification information and / or address information.

[00127] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00128] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00129] In some applications, the fifth application information may include at least one of the following:

[00130] detection task identification information;

[00131] quality information needed to perform the detection task; and

[00132] a detection scenario / method when performing the detection task.

[00133] It is understood that the EU identification information in fifth request information is SUPI information, SUCI information, GPSI information and the like used for internal consultation on the main network, as compared to third request information, whereas third request information does not impose such limitations. Petition 870250083541, dated 09 / 17 / 2025, page 33 / 313 27 / 126

[00134] In S204, AMF determines the detection scenario / method when performing the detection task.

[00135] AMF can determine, based on the fifth request information, that the detection scenario / method when performing the detection task is UE-gNB uplink detection. Alternatively, AMF can determine that the detection scenario / method when performing the detection task is UE-gNB downlink detection.

[00136] In S205, AMF sends the fifth request information to the EU.

[00137] In S206, AMF sends the fifth request information to the Service RAN.

[00138] It should be noted that, based on operations S205 to S206, AMF may send fifth request information to the UE or to the Service RAN; alternatively, AMF may send fifth request information to both the UE and the Service RAN, which is not limited by the arrangements of this disclosure.

[00139] It should also be noted that AMF may first send the fifth request information to the UE and then send the fifth request information to the Service RAN. Alternatively, AMF may first send the fifth request information to the Service RAN and then send the fifth request information to the UE. Alternatively, AMF may send the fifth request information to the UE and to the Service RAN simultaneously, which is not limited by the arrangements of this disclosure.

[00140] In S207, the Service RAN communicates with the UE.

[00141] The Service RAN communicates with the UE, from Petition 870250083541, dated 09 / 17 / 2025, p. 34 / 313 28 / 126 so that the UE can obtain downlink reference signals from the Service RAN and thus measure downlink reference signals; and / or the Service RAN can obtain uplink reference signals from the UE and thus measure uplink reference signals.

[00142] In S208, the UE determines the outcome of performing the detection task.

[00143] If the UE measures the downlink reference signals of the Service RAN, the UE can determine the outcome of performing the detection task based on a measurement result.

[00144] For example, the result of performing the detection task may be that detection data is generated.

[00145] In S209, the EU sends the fourth information to the AMF.

[00146] The fourth piece of information may include the result of performing the detection task.

[00147] It should be noted that the fourth piece of information can be called detection instruction feedback.

[00148] In S210, AMF sends the fourth piece of information to SF.

[00149] In S211, SF sends the fifth piece of information to the consumer's NF.

[00150] The fifth piece of information may include the result of performing the detection task.

[00151] It should be noted that the fifth pieces of information can be called feedback of Petition 870250083541, dated 09 / 17 / 2025, p. 35 / 313 29 / 126 detection task request.

[00152] It should also be noted that, in practical applications, the Service RAN can determine the result of performing the detection task and send the result of performing the detection task to the AMF.

[00153] It should also be noted that SF can send the fifth request information directly to the UE and / or to the Service RAN.

[00154] Additionally, if the fifth request information includes SF attribute information, the UE and / or the Service RAN may send a response message from the third request message directly to the SF based on the SF attribute information.

[00155] In some modalities, the SF attribute information may include at least one of the following:

[00156] SF identification information;

[00157] SF instance information; or

[00158] SF address information.

[00159] In the related technique, when an UE is detected, the detection target can be a given UE, an object and environment around the UE, or similar. The UE generally uses the Service RAN as an auxiliary RAN to aid in detection. However, in practical applications, the Service RAN may not be a better auxiliary RAN for specific detection tasks. For example, a signal transmission path between the UE and the Service RAN is not in the same direction as the detection target relative to the UE's position. Alternatively, due to the accuracy demands and task-specific demands of the detection task (such as the need to detect a UE trajectory, etc.), the UE Petition 870250083541, dated 09 / 17 / 2025, p. 36 / 313 30 / 126 requires additional auxiliary RANs besides the Service RAN to assist in detection. Therefore, determining which auxiliary RANs to use for UE when performing a detection task is an urgent problem to be solved.

[00160] Based on this, the embodiments of the present disclosure provide a method of communication in which a first network element (such as SF) can send the first request information to a terminal device. The first request information is used to query attribute information of each of the first M RANs (i.e., the auxiliary RANs above), and the first RANs are used to perform a discovery task with the terminal device. In this way, the first network element sends the first request information to the terminal device so that the first network element can determine the auxiliary RANs when the terminal device performs the discovery task based on the first request information.

[00161] It should be noted that in the following embodiments, the determination of auxiliary RANs when the terminal device performs the detection task is performed before obtaining the result of performing the detection task. For example, as illustrated in Figure 2, the operation of determining auxiliary RANs when the UE performs the detection task can be performed between S202 and S203. That is, the SF can first send the first request information to the UE before sending the fifth request information to the UE, so that the auxiliary RANs, when the UE performs the detection task, are consulted before obtaining the result of performing the detection task, thus the RANs Petition 870250083541, dated 09 / 17 / 2025, page 37 / 313 31 / 126 auxiliaries can help the EU to perform the detection task subsequently.

[00162] Figure 3 is a flow diagram of a communication method provided by an embodiment of the present disclosure. As illustrated in Figure 3, the communication method includes the following operation S310.

[00163] In S310, the first network element sends the first request information to the terminal device.

[00164] The first request information is used to query attribute information for each of the first M RANs, and the first RANs are used to perform a discovery task with the terminal device.

[00165] M is a positive integer.

[00166] Consequently, the terminal device can receive the first request information from the first network element.

[00167] It should be noted that the initial request information may be referred to as an auxiliary RAN discovery request. Alternatively, the initial request information may also be referred to as a detection task request, and the detection task request carries indication information to indicate the discovery of auxiliary RANs. Alternatively, the initial request information may also be referred to as a detection task request, and the detection task request includes a selection of UE-gNB uplink detection and UE-gNB downlink detection as the detection scenario / method, so that the terminal device can implicitly know that it needs to discover the RANs. Petition 870250083541, dated 09 / 17 / 2025, page 38 / 313 32 / 126 assistants to perform the detection task.

[00168] It should also be noted that the first network element may be an SF or other network elements, which is not limited by the modalities of the present disclosure.

[00169] It should also be noted that the detection task may include at least one of:

[00170] a user execution action;

[00171] respiratory monitoring;

[00172] a speed of movement of the terminal device;

[00173] environmental imaging; and

[00174] monitoring of weather conditions.

[00175] In some embodiments, the attribute information of a first RAN includes identification information and / or address information of the first RAN.

[00176] It should be noted that the initial request information may include at least one of the following:

[00177] detection task identification information;

[00178] identification information of the first network element;

[00179] instance information of the first network element; or

[00180] address information of the first network element.

[00181] In embodiments of the present disclosure, in order to enable the terminal device to process the first request information in a timely manner, the first network element may send indication information to the terminal device. The indication information is used Petition 870250083541, dated 09 / 17 / 2025, pp. 39 / 313 33 / 126 to indicate the terminal device to query the attribute information of each of the first M RANs based on the first request information.

[00182] Consequently, the terminal device can receive the indication information from the first network element.

[00183] In some embodiments, before the first network element sends the first request information to the terminal device, the method may additionally include that: the first network element may receive third request information. The third request information is configured to request obtaining a result from the completion of the detection task by the terminal device.

[00184] It should be noted that the third request information may be referred to as a detection task request. It should be understood that, after receiving the third request information, the first network element may send the first request information to the terminal device in response to the third request information to query the attribute information of the auxiliary RANs, so that the first network element can obtain the attribute information of the auxiliary RANs based on the assistance of the terminal device.

[00185] In some modalities, the third request information may be information sent by the consumer invoice to the first network element.

[00186] It should be noted that the consumer NF can be at least one of AF, NEF and the terminal device, or it can be other network elements or devices, which Petition 870250083541, dated 09 / 17 / 2025, page 40 / 313 34 / 126 is not limited by the terms of this disclosure.

[00187] For example, the consumer invoice can be the NEF, and the NEF can send third-party request information to the first network element.

[00188] For example, the consumer invoice can be the NEF and the AF. The AF can send third-party request information to the NEF, and the NEF can send third-party request information to the first network element.

[00189] In some modalities, the third request information may include terminal device attribute information.

[00190] Additionally, terminal device attribute information may include terminal device identification information and / or address information.

[00191] It should be noted that the terminal device identification information may include at least one of the following: SUPI information, SUCI information, and GPSI information.

[00192] In some embodiments, the first network element or other network elements (such as the NEF, etc.) can map the terminal device identification information, and the identification information is converted into SUPI information, SUCI information, GPSI information, etc., which can ultimately be used directly for internal querying within the main network.

[00193] For example, the first network element can map the terminal device's identification information by querying other network elements. Petition 870250083541, dated 09 / 17 / 2025, page 41 / 313 35 / 126 (e.g., AMF / UDR / UDM) or by consulting local information, thus obtaining SUPI information, SUCI information, GPSI information, and similar information for internal consultation within the main network.

[00194] Note that terminal device address information may include IP address information and / or MAC address information.

[00195] It should be understood that the terminal device above is a target terminal device. After determining the attribute information of the terminal device, the first network element can determine a second RAN (i.e., the Service RAN above) where the terminal device is currently parked based on the attribute information of the terminal device. Alternatively, the first network element can first determine the attribute information of the RAN where the terminal device is currently parked and then determine the terminal device based on the attribute information of the RAN where the terminal device is currently parked.

[00196] It should also be noted that, in embodiments of the present disclosure, the target terminal device may be determined by the first network element, or may be determined by other network elements (such as the UE Service AMF or UDM, etc.), which is not limited by the embodiment of the present disclosure.

[00197] In some applications, the third application information may additionally include at least one of the following:

[00198] detection task identification information; Petition 870250083541, dated 09 / 17 / 2025, p. 42 / 313 36 / 126

[00199] quality information needed to perform the detection task; and

[00200] a detection scenario / method when performing the detection task.

[00201] The quality information required to perform the detection task may be precision information necessary to perform the detection task, or it may be other information, which is not limited by the embodiments of the present disclosure.

[00202] The detection scenario / method when performing the detection task can be one of the following: single gNB detection, gNB-gNB detection, UE-gNB uplink detection, UE-gNB downlink detection, single UE detection, and UE-UE detection.

[00203] In the embodiments of the present disclosure, the detection scenario / method when performing the detection task mainly includes UEgNB uplink detection and / or UE-gNB downlink detection.

[00204] The embodiments of the present disclosure provide the method of communication in which the first network element can send the first request information to the terminal device. The first request information is used to query attribute information of each of the first M RANs, and the first RANs are used to perform a discovery task with the terminal device. In this way, the first network element sends the first request information to the terminal device so that the first network element can determine the auxiliary RANs when the terminal device performs the discovery task based on the first request information. Petition 870250083541, dated 09 / 17 / 2025, page 43 / 313 37 / 126 request.

[00205] Based on S310, after the terminal device receives the first request information from the first network element, there are two processing methods. One processing method is that the terminal device can request that the second RAN query the attribute information of each of the first M RANs and send the attribute information of each of the first M RANs directly or indirectly to the first network element, so that the first network element can obtain the attribute information of each of the first M RANs. Optionally, the terminal device can send measurement information from each of the first M RANs and signal strength from each of the first M RANs directly or indirectly to the first network element.Another processing method is that the terminal device can send the measurement information from each of the first M RANs to the first network element, the first network element can send the measurement information from each of the first M RANs to the second network element, and the second network element can determine the attribute information of each of the first M RANs based on the measurement information from each of the first M RANs, and send the attribute information of each of the first M RANs to the first network element, so that the first network element can obtain the attribute information of each of the first M RANs. Optionally, the terminal device can also send the signal strength of each of the first M RANs to the first network element.

[00206] That is, based on the two ways of Petition 870250083541, dated 09 / 17 / 2025, page 44 / 313 38 / 126 terminal device processing, the first network element can receive the first information, and the first information includes at least one of the following: attribute information from each of the first M RANs, measurement information from each of the first M RANs, or signal strength from each of the first M RANs. The first network element can obtain attribute information from each of the first M RANs directly or indirectly based on the first information.

[00207] It should be noted that the information interaction between network elements or devices in the following modes can be described in conjunction with at least one of Figure 4, Figure 5, and Figure 6. In the following modes, the second RAN can be a Service RAN, the terminal device can be UE, the first network element can be an SF, and the first RAN can be a Neighbor RAN.

[00208] In method A, after receiving the first request information from the first network element (i.e., S403 or S503), the terminal device can send the fourth request information to the second RAN (i.e., S405 or S505). The fourth request information is used to query attribute information from each of the first M RANs, and the fourth request information includes measurement information from each of the first P RANs.

[00209] Consequently, the second RAN can receive the fourth request information from the terminal device.

[00210] The first P RANs include the first M RANs, and P is a positive integer greater than or equal to M.

[00211] There are associative relationships between the Petition 870250083541, dated 09 / 17 / 2025, page 45 / 313 39 / 126 respective measurement information of the first P RANs and the respective attribute information of the first P RANs.

[00212] For example, the measurement information for each of the first P RANs may have a one-to-one mapping relationship with the attribute information for each of the first P RANs.

[00213] It should be noted that the fourth request information may be referred to as an auxiliary RAN discovery request and a measurement information report.

[00214] In some embodiments, measurement information may include cell identification information and / or tracking area identification information.

[00215] In some modes, the fourth request information may include identification information for the detection task and at least one of the following:

[00216] identification information of the first network element;

[00217] instance information of the first network element; or

[00218] address information of the first network element.

[00219] In view of the different ways of processing after the second RAN receives the fourth request information from the terminal device, there are the following two possible implementations to obtain the attribute information from the auxiliary RANs by the first network element.

[00220] In a possible implementation, after receiving the fourth request information from the terminal device (i.e., S405), the second RAN sends information to Petition 870250083541, dated 09 / 17 / 2025, page 46 / 313 40 / 126 attribute of each of the first M RANs directly to the first network element (i.e., S407).

[00221] In some embodiments, the second RAN can determine the attribute information of each of the first P RANs according to the measurement information of each of the first P RANs based on the association relationships between the respective measurement information of the first P RANs and the respective attribute information of the first P RANs.

[00222] Additionally, the second RAN can determine attribute information from each of the first P RANs based on measurement information from each of the first P RANs, information from locally stored neighboring cells, information from neighboring base stations, and similar data.

[00223] In some modes, the fourth request information may additionally include the signal strength of each of the first P RANs.

[00224] There are association relationships between the respective signal intensities of the first P RANs and the respective measurement information of the first P RANs.

[00225] In some modes, the second RAN can select the first M RANs from the first P RANs (i.e., S406).

[00226] It should be noted that the first M RANs can be randomly selected by the second RAN from the first P RANs. Alternatively, the first M RANs can be selected by the second RAN from the first P RANs according to the signal strength of each of the first P RANs. Petition 870250083541, dated 09 / 17 / 2025, page 47 / 313 41 / 126

[00227] For example, the second RAN can select the first M RANs with the highest signal strength from the first P RANs.

[00228] For example, the second RAN can select M first RANs whose signal strength is greater than a first threshold of the P first RANs.

[00229] It should be noted that the first threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00230] It should also be noted that when the second RAN selects the first M RANs from the first P RANs according to the signal strength of each of the first P First, the second RAN can determine the signal strength of each of the first M RANs based on the signal strength of each of the first P RANs. Second, the second RAN can determine the measurement information of each of the first M RANs based on the association relationships between the signal strengths of the first M RANs and the respective measurement information of the first M RANs. Then, the second RAN can determine the attribute information of each of the first M RANs based on the association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs. Finally, the second RAN can determine the first M RANs based on the attribute information of each of the first M RANs.

[00231] In some embodiments, the second RAN may send the first information to the first network element (i.e., S407). Petition 870250083541, dated 09 / 17 / 2025, page 48 / 313 42 / 126

[00232] Consequently, the first network element can receive the first information from the second RAN.

[00233] The initial information may include the attribute information for each of the first M RANs.

[00234] It should be noted that the first information may be referred to as an auxiliary report of RAN attribute information.

[00235] In some embodiments, the initial information additionally includes measurement information for each of the first M RANs and the signal strength for each of the first M RANs.

[00236] There are association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs, and there are association relationships between the respective signal strengths of the first M RANs and the respective measurement information of the first M RANs.

[00237] In some forms, the initial information may additionally include AMF identification information corresponding to the first M RANs, respectively.

[00238] Additionally, the second RAN can send the initial information and the identification information of the detection task to the first network element based on at least one of the following: identification information of the first network element, instance information of the first network element, and address information of the first network element.

[00239] In this way, after receiving the fourth request information from the terminal device, the RAN in Petition 870250083541, dated 09 / 17 / 2025, page 49 / 313 43 / 126 where the terminal device is currently stationed can determine the attribute information of each of the auxiliary PRANs according to the measurement information of each of the auxiliary PRANs based on the association relationships between the respective measurement information of the auxiliary PRANs and the respective attribute information of the auxiliary PRANs. Furthermore, auxiliary RANs M are selected from the auxiliary PRANs, and then the attribute information of each of the auxiliary RANs M is sent to the first network element, so that the first network element can obtain the attribute information of the auxiliary RANs.

[00240] In another possible implementation, after receiving the fourth request information from the terminal device (i.e., S505), the second RAN can send attribute information from each of the first P RANs to the terminal device (i.e., S506), and then the terminal device sends attribute information from each of the first M RANs to the first network element (i.e., S508).

[00241] In some embodiments, the second RAN can determine the attribute information of each of the first P RANs according to the measurement information of each of the first P RANs based on the association relationships between the respective measurement information of the first P RANs and the respective attribute information of the first P RANs.

[00242] Additionally, the second RAN can determine attribute information for each of the first P RANs based on measurement information from each of the first P RANs, locally stored neighboring cell information, neighboring base station information, and Petition 870250083541, dated 09 / 17 / 2025, page 50 / 313 44 / 126 similar.

[00243] In some embodiments, the second RAN can send the third information to the terminal device (i.e., S506).

[00244] Consequently, the terminal device can receive third-party information from the second RAN.

[00245] The third information may additionally include the attribute information for each of the first P RANs.

[00246] It should be noted that the third piece of information may be referred to as attribute information feedback.

[00247] In some forms, the third information may additionally include AMF identification information corresponding to the first M RANs, respectively.

[00248] In some embodiments, the terminal device can select the first M RANs from the first P RANs (S507).

[00249] It should be noted that the first M RANs can be randomly selected by the terminal device from the first P RANs. Alternatively, the first M RANs can be selected by the terminal device from the first P RANs according to the signal strength of each of the first P RANs.

[00250] For example, the terminal device can select the first M RANs with the highest signal strength from the first P RANs.

[00251] For example, the terminal device can select the first M RANs whose intensity of Petition 870250083541, dated 09 / 17 / 2025, page 51 / 313 45 / 126 signal is greater than one third of the threshold of the first P RANs.

[00252] It should be noted that the third threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00253] It should also be noted that when the terminal device selects the first M RANs from the first P RANs according to the signal strength of each of the first P RANs, the terminal device can first determine the signal strength of each of the first M RANs based on the signal strength of each of the first P RANs. Secondly, the terminal device can determine the measurement information of each of the first M RANs based on the association relationships between the respective signal strengths of the first M RANs and the respective measurement information of the first M RANs. Then, the terminal device can determine the attribute information of each of the first M RANs based on the association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs.Finally, the terminal device can determine the first M RANs based on the attribute information of each of the first M RANs.

[00254] In some embodiments, the terminal device may send the first information to the first network element (i.e., S508).

[00255] Consequently, the first network element can receive the first information from the terminal device.

[00256] The initial information includes the Petition 870250083541, dated 09 / 17 / 2025, page 52 / 313 46 / 126 attribute information for each of the first M RANs.

[00257] In some embodiments, the initial information may additionally include measurement information for each of the first M RANs and the signal strength for each of the first M RANs.

[00258] There are association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs, and there are association relationships between the respective signal strengths of the first M RANs and the respective measurement information of the first M RANs.

[00259] In some forms, the initial information may additionally include AMF identification information corresponding to the first M RANs, respectively.

[00260] Additionally, the terminal device can send the initial information and the identification information of the detection task to the first network element based on at least one of the following: identification information of the first network element, instance information of the first network element, and address information of the first network element.

[00261] In this way, after receiving the fourth request information from the terminal device, the RAN in which the terminal device is currently stationed can determine the attribute information of each of the auxiliary PRANs according to the measurement information of each of the auxiliary PRANs based on the association relationships between the respective measurement information of the auxiliary PRANs and the respective attribute information of the auxiliary PRANs, Petition 870250083541, dated 09 / 17 / 2025, page 53 / 313 47 / 126 and send the attribute information of each of the auxiliary P RANs to the terminal device. Additionally, the auxiliary M RANs are selected from the auxiliary P RANs, and then the attribute information of each of the auxiliary M RANs is sent to the first network element, so that the first network element can obtain the attribute information of the auxiliary RANs.

[00262] Based on method A, the terminal device needs to measure the signal first (i.e., S404 or S504) before sending the fourth request information to the second RAN (i.e., S405 or S505).

[00263] In some embodiments, the terminal device can determine the measurement information of each of the first P RANs by measuring the downlink reference signals sent by the first P RANs.

[00264] In some embodiments, the terminal device can determine the signal strength of each of the first P RANs by measuring the downlink reference signals sent by the first P RANs.

[00265] In this way, the terminal device can send the measurement information from the auxiliary RANs and / or the signal strength from the auxiliary RANs to the second RAN, so that the first network element can finally obtain the attribute information from the auxiliary RANs.

[00266] In method B, after receiving the first request information from the first network element (i.e., S603), the terminal device can send the first information to the first network element (i.e., S605), and the first information includes measurement information from each of the first M RANs. Petition 870250083541, dated 09 / 17 / 2025, page 54 / 313 48 / 126

[00267] There are association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs.

[00268] For example, the measurement information for each of the first M RANs may have a one-to-one mapping relationship with the attribute information for each of the first M RANs.

[00269] It should be noted that the initial information may be referred to as a measurement information report.

[00270] In some embodiments, measurement information may include cell identification information and / or tracking area identification information.

[00271] In some embodiments, the terminal device may send the first information to the first network element (i.e., S605).

[00272] Consequently, the first network element can receive the first information from the terminal device.

[00273] The initial information may include measurement information for each of the first M RANs.

[00274] Additionally, the initial information may also include the signal strength of each of the first M RANs.

[00275] There are association relationships between the respective signal intensities of the first M RANs and the respective measurement information of the first M RANs.

[00276] In some modes, after receiving the first information from the terminal device, the first network element can send the second information from Petition 870250083541, dated 09 / 17 / 2025, page 55 / 313 49 / 126 request for the second network element (i.e., S606).

[00277] Consequently, the second network element can receive the second request information from the first network element.

[00278] The second request information is used to query the attribute information for each of the first M RANs, and the second request information includes the measurement information for each of the first M RANs.

[00279] It should be noted that the second request for information may be referred to as an auxiliary RAN attribute information request.

[00280] In some embodiments, the second network element can determine the attribute information of each of the first M RANs according to the measurement information of each of the first M RANs based on the association relationships between the respective measurement information of the first M RANs and the respective attribute information of the first M RANs.

[00281] Note that the second network element can be one of the following: an AMF where the terminal device is currently stationed, a second RAN where the terminal device is currently stationed, a UDR, or an SF (different from the first network element).

[00282] In some embodiments, the second network element can send the second information to the first network element (i.e., S607).

[00283] Consequently, the first network element can receive the second information from the second network element. Petition 870250083541, dated 09 / 17 / 2025, page 56 / 313 50 / 126

[00284] The second set of information includes the attribute information for each of the first M RANs.

[00285] It should be noted that the second piece of information may be referred to as attribute information feedback.

[00286] In this way, after receiving the first request information from the first network element, the terminal device can send the measurement information of each of the auxiliary M RANs to the first network element, and after receiving the measurement information of each of the auxiliary M RANs, the first network element can send the measurement information of each of the auxiliary M RANs to the second network element. The second network element determines the attribute information of each of the auxiliary M RANs according to the measurement information of each of the auxiliary M RANs based on the association relationships between the respective measurement information of the auxiliary M RANs and the respective attribute information of the auxiliary M RANs, and sends the attribute information of each of the auxiliary M RANs to the first network element, so that the first network element can obtain the attribute information of the auxiliary RANs.

[00287] Based on method B, before sending the first information to the first network element (i.e., S605), the terminal device must measure the signal first (i.e., S604).

[00288] In some embodiments, the terminal device can determine the measurement information of each of the first M RANs by measuring the downlink reference signals sent by the first M RANs. Petition 870250083541, dated 09 / 17 / 2025, page 57 / 313 51 / 126

[00289] In some embodiments, the terminal device can determine the signal strength of each of the first M RANs by measuring the downlink reference signals sent by the first M RANs.

[00290] In this way, the terminal device can send the measurement information from the auxiliary RANs and / or the signal strength from the auxiliary RANs to the first network element, so that the first network element can finally obtain the attribute information from the auxiliary RANs.

[00291] In some embodiments, the first network element may select the first N RANs from the first M RANs (i.e., S408 or S509 or S608).

[00292] N is a positive integer less than or equal to M.

[00293] It should be noted that the first N RANs can be randomly selected by the first network element from the first M RANs. Alternatively, the first N RANs can be selected by the first network element from the first M RANs according to the signal strength of each of the first M RANs.

[00294] For example, the first network element can select the first N main RANs with the highest signal strength from the first M RANs.

[00295] For example, the first network element can select the first N RANs whose signal strength is greater than a second threshold of the first M RANs.

[00296] Note that the second threshold can be a predefined parameter value or a parameter value. Petition 870250083541, dated 09 / 17 / 2025, page 58 / 313 52 / 126 defined in another way, which is not limited by the modalities of the present disclosure.

[00297] It should also be noted that when the first network element selects the first N RANs from the first M RANs based on the signal strength of each of the first M RANs, the first network element can first determine the signal strength of each of the first N RANs based on the signal strength of each of the first M RANs. Secondly, the first network element can determine the measurement information of each of the first N RANs based on the association relationships between the respective signal strengths of the first N RANs and the respective measurement information of the first N RANs. Then, the first network element can determine the attribute information of each of the first N RANs based on the association relationships between the respective measurement information of the first N RANs and the respective attribute information of the first N RANs.Finally, the first network element can determine the first N RANs based on the attribute information of each of the first N RANs.

[00298] In some embodiments, the first network element can establish a communication connection with the first N RANs according to the attribute information of each of the first N RANs (i.e., S409 or S510 or S609), and the communication connection is used to obtain a result of performing the detection task.

[00299] For example, the first network element can query attribute information from the first RAN via NRF / AMF or locally stored information to establish a user plane connection. Petition 870250083541, dated 09 / 17 / 2025, page 59 / 313 53 / 126 Alternatively, the first network element can obtain identification information from an AMF corresponding to the first RAN by consulting the NRF or locally stored information and perform the control plane interaction through the AMF. Alternatively, if the first network element obtains the identification information from the AMF corresponding to the first RAN, the first network element can retrieve relevant information from the corresponding first RAN from the AMF through a control plane, thus establishing a link to the user plane with the first RAN or performing the control plane interaction through the AMF.

[00300] In some embodiments, after the first network element establishes a communication connection with the first N RANs, the fifth request information can be sent to the terminal device, the second RAN and the first N RANs (i.e., S410a-S410c, S511a-S511c or S610a-S610c), respectively.

[00301] Consequently, the terminal device, the second RAN, and the first N RANs can receive the fifth request information from the first network element, respectively.

[00302] The fifth request information can be used to request the result of performing the detection task.

[00303] In some modes, the fifth request information may include at least one of the following:

[00304] detection task identification information;

[00305] quality information needed to perform the detection task; and Petition 870250083541, dated 09 / 17 / 2025, p. 60 / 313 54 / 126

[00306] a detection scenario / method when performing the detection task.

[00307] In some modes, the fifth request information may include terminal device attribute information.

[00308] Additionally, terminal device attribute information may include terminal device identification information and / or address information.

[00309] It should be noted that the terminal device identification information may include at least one of the following: SUPI information, SUCI information, and GPSI information.

[00310] It should also be noted that the terminal device address information may include IP address information and / or MAC address information.

[00311] It is understood that the terminal device identification information in the fifth request information is SUPI information, SUCI information, GPSI information and the like used for internal querying on the main network, as compared to the third request information, whereas the third request information does not impose such limitations.

[00312] It should also be noted that an order in which the first network element sends the fifth request information to the terminal device, the first network element sends the fifth request information to the second RAN, and the first network element sends the fifth request information to the first N RANs is not limited by the embodiments of the present disclosure. Petition 870250083541, dated 09 / 17 / 2025, page 61 / 313 55 / 126

[00313] In some embodiments, after the terminal device, the second RAN and the first N RANs receive the fifth request information from the first network element, respectively, communication can be established between the terminal device, the second RAN and the first N RANs (i.e., S411, S512 or S611), and the communication is used to obtain the result of performing the detection task.

[00314] It should be noted that, through communication between the terminal device, the second RAN and the first N RANs, reference signals can be obtained by at least one of the terminal devices, the second RAN and the first N RANs, so that reference signals can be measured.

[00315] For example, the second RAN communicates with the terminal device and the first N RANs, so that the second RAN can obtain the reference signals sent by the terminal device and the first N RANs and, in this way, can measure the reference signals.

[00316] In some embodiments, if the second RAN measures the reference signals sent by the terminal device and the first N RANs, the second RAN can determine the outcome of performing the detection task based on the measurement result (i.e., S412).

[00317] For example, the result of performing the detection task may be that detection data is generated.

[00318] In some embodiments, if the result of performing the detection task is determined by the second RAN, the second RAN may send the fourth information to the first network element (i.e., S413). Petition 870250083541, dated 09 / 17 / 2025, p. 62 / 313 56 / 126

[00319] Consequently, the first network element can receive the fourth information from the second RAN.

[00320] The fourth piece of information includes the result of performing the detection task.

[00321] It should be noted that, in practical applications, the terminal device and / or the first N RANs can also determine the result of performing the detection task (i.e., S513 or S612) and send the result of performing the detection task to the first network element (i.e., S514 or S613).

[00322] It should also be noted that at least one of the second RANs, the terminal device and the first N RANs can send the fourth information to the AMF and then the AMF forwards the fourth information to the first network element.

[00323] In some modes, after receiving the fourth piece of information, the first network element can send the fifth piece of information to the consumer invoice (i.e., S414 or S515 or S614).

[00324] The fifth piece of information includes the result of performing the detection task.

[00325] It should be noted that, in embodiments of the present disclosure, the second RAN may be a different RAN from the first RANs, and the second RAN may be one of the first RANs, and whether or not there is an inclusion relationship between the second RAN and the first RANs depends on a specific application scenario, which is not limited by embodiments of the present disclosure.

[00326] The modalities of the present disclosure provide a method of communication, after the terminal device Petition 870250083541, dated 09 / 17 / 2025, page 63 / 313 57 / 126 to receive the first request information from the first network element, there are two processing methods. One processing method is that the terminal device can request that the RAN where the terminal device is currently stationed consult the attribute information of the auxiliary RANs. Another processing method is that the terminal device sends the measurement information from the auxiliary RANs directly to the first network element. Based on these two processing methods, the first network element can acquire the auxiliary RANs when the terminal device performs the detection task.

[00327] The communication method provided by the above modalities will be described in detail below, with reference to specific application scenarios.

[00328] In the embodiments of the present disclosure, when the Neighboring RANs (i.e., the first RANs / auxiliary RANs above) are obtained when the UE performs the detection task, there are primarily three scenarios as follows: the Service RAN (i.e., the second RAN above) reports the UE assigns information from each of the Neighboring M RANs to the SF; the UE reports assign information from each of the Neighboring M RANs to the SF; the UE reports the measurement information from each of the Neighboring M RANs to the SF, and the SF queries the attribute information from each of the Neighboring M RANs based on the measurement information from each of the Neighboring M RANs. The detailed flow of obtaining the Neighboring RANs when the UE performs the detection task in these three scenarios is described below with reference to Figure 4 through Figure 6.

[00329] In scenario no. C, the Service RAN of Petition 870250083541, dated 09 / 17 / 2025, p. 64 / 313 58 / 126 EU reports assign information from each of the neighboring M RANs to the SF.

[00330] Figure 4 is a second detailed flowchart of a method for detecting UE provided by an embodiment of the present disclosure. As illustrated in Figure 4, after receiving a discovery request (i.e., first request information) from Neighboring RANs, the UE performs signal measurement and then reports a signal measurement result (i.e., measurement information) and the discovery request from the Neighboring RANs (i.e., fourth request information) to the Service RAN, and the Service RAN converts the UE's signal measurement result into attribute information from the Neighboring RANs, and reports the attribute information from the Neighboring RANs to the SF, and the SF makes a decision. The detailed flow of the method may include the following operations.

[00331] In S401, the consumer invoice sends the third-party request information to the SF.

[00332] Consequently, SF may receive third-party request information.

[00333] Third-party request information can be used to request that the EU obtain a detection task completion result.

[00334] It should be noted that the consumer NF may be at least one of AF, NEF and UE, or may be other network elements or devices, which is not limited by the purposes of this disclosure.

[00335] For example, the consumer invoice can be the NEF, and the NEF can send third-party request information to the SF. Petition 870250083541, dated 09 / 17 / 2025, page 65 / 313 59 / 126

[00336] For example, the consumer invoice can be the NEF and the AF. The AF can send third-party request information to the NEF, and the NEF can send third-party request information to the SF.

[00337] In some modes, the detection task may include at least one of:

[00338] a user execution action;

[00339] respiratory monitoring;

[00340] a speed of movement of the terminal device;

[00341] environmental imaging; and

[00342] monitoring of weather conditions.

[00343] In some modalities, the third-party request information may include EU attribute information.

[00344] Additionally, EU attribute information may include EU identification and / or address information.

[00345] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00346] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00347] In some applications, the third-party application information may include at least one of the following:

[00348] detection task identification information;

[00349] quality information needed to perform the detection task; and Petition 870250083541, dated 09 / 17 / 2025, p. 66 / 313 60 / 126

[00350] a detection scenario / method when performing the detection task.

[00351] The quality information required to perform the detection task may be precision information necessary to perform the detection task, or it may be other information, which is not limited by the embodiments of the present disclosure.

[00352] The detection scenario / method when performing the detection task can be one of the following: single gNB detection, gNB-gNB detection, UE-gNB uplink detection, UE-gNB downlink detection, single UE detection, and UE-UE detection.

[00353] In the embodiments of the present disclosure, the detection scenario / method when performing the detection task mainly includes uplink detection of UEgNB and / or downlink detection of UE-gNB.

[00354] In S402, SF determines the UE attribute information.

[00355] It should be noted that the SF or other network elements (such as the NEF, etc.) can map the UE identification information, and the identification information is converted into SUPI information, SUCI information, GPSI information, etc., which can be used directly for internal querying within the main network.

[00356] For example, the SF can map UE identification information by consulting other network elements (e.g., AMF / UDR / UDM) or by consulting local information, thus obtaining SUPI information, SUCI information, GPSI information and the like for Petition 870250083541, dated 09 / 17 / 2025, page 67 / 313 61 / 126 internal consultation within the main network.

[00357] Note that the UE above is the target UE. After determining the UE attribute information, the SF can determine the Service RAN based on the UE attribute information. Alternatively, the SF can first determine the Service RAN attribute information and then determine the UE based on the Service RAN attribute information.

[00358] It should also be noted that, in the embodiments of the present disclosure, the target UE may be determined by SF, or may be determined by other network elements (such as the UE Service AMF or UDM, etc.), which is not limited by the embodiment of the present disclosure.

[00359] In S403, SF sends the first request information to the EU.

[00360] Consequently, the EU can receive the first request information from the SF.

[00361] The initial request information can be used to query attribute information for each of the neighboring M RANs, and the neighboring RANs can be used to assist the UE in performing the detection task.

[00362] M is a positive integer.

[00363] It should be noted that the initial request information may be referred to as an auxiliary RAN discovery request. Alternatively, the initial request information may also be referred to as a detection task request, and the detection task request carries indication information to indicate the discovery of auxiliary RANs. Alternatively, the initial request information may also be referred to Petition 870250083541, dated 09 / 17 / 2025, page 68 / 313 62 / 126 detection task request, and the detection task request includes a selection of UE-gNB uplink detection and UE-gNB downlink detection as the detection scenario / method, so that the terminal device can implicitly know that it needs to discover the auxiliary RANs to perform the detection task.

[00364] In some embodiments, the attribute information of a Neighboring RAN includes identification information and / or address information of the Neighboring RAN.

[00365] In some applications, the initial application information may include at least one of the following:

[00366] detection task identification information;

[00367] SF identification information;

[00368] SF instance information; or

[00369] SF address information.

[00370] In some modalities, the SF may also send nomination information to the EU.

[00371] Consequently, the EU can receive the SF's indication information.

[00372] The indication information is used to indicate the UE to consult attribute information from each of the neighboring M RANs based on the initial request information.

[00373] In S404, the UE performs signal measurement.

[00374] In some embodiments, the UE can determine the measurement information of each of the Neighboring P RANs by measuring the downlink reference signals sent by the Neighboring P RANs.

[00375] There are associative relationships between the Petition 870250083541, dated 09 / 17 / 2025, page 69 / 313 63 / 126 respective measurement information of the neighboring P RANs and the respective attribute information of the neighboring P RANs.

[00376] P Neighboring RANs may include M Neighboring RANs and P is a positive integer greater than or equal to M.

[00377] For example, the measurement information of each of the Neighboring P RANs may have a one-to-one mapping relationship with the attribute information of each of the Neighboring P RANs.

[00378] In some embodiments, measurement information may include cell identification information (cell ID) and / or tracking area identification information (TA ID).

[00379] In some modes, the UE can determine the signal strength of each of the neighboring P RANs by measuring the downlink reference signals sent by the neighboring P RANs.

[00380] There are association relationships between the respective signal intensities of neighboring PRANs and the respective measurement information of neighboring PRANs.

[00381] In S405, the UE sends the fourth request information to the Service RAN.

[00382] Consequently, the Service RAN can receive the fourth request information from the EU.

[00383] The fourth request information can be used to query attribute information for each of the Neighboring RANs M, and the fourth request information can include measurement information for each of the Neighboring RANs P.

[00384] Additionally, the fourth request information includes the signal strength of Petition 870250083541, dated 09 / 17 / 2025, page 70 / 313 64 / 126 each of the neighboring P RANs.

[00385] In some modalities, the fourth request information may additionally include identification information for the detection task and at least one of the following:

[00386] SF identification information;

[00387] SF instance information; or

[00388] SF address information.

[00389] In S406, the Service RAN selects M Neighboring RANs.

[00390] In some embodiments, the Service RAN may determine the attribute information of each of the Neighboring RANs P according to the measurement information of each of the Neighboring RANs P based on the association relationships between the respective measurement information of the Neighboring RANs P and the respective attribute information of the Neighboring RANs P.

[00391] In addition, the Service RAN can determine attribute information for each of the Neighboring PRANs based on measurement information from each of the Neighboring PRANs, locally stored neighboring cell information, neighboring base station information, and the like.

[00392] It should be noted that the Neighboring M RANs can be randomly selected by the Service RAN from the Neighboring P RANs. Alternatively, the Neighboring M RANs can be selected by the Service RAN from the Neighboring P RANs according to the signal strength of each of the Neighboring P RANs.

[00393] For example, the Service RAN Petition 870250083541, dated 09 / 17 / 2025, page 71 / 313 65 / 126 can select the main neighboring M RANs with the highest signal strength from the neighboring P RANs.

[00394] For example, the Service RAN can select M Neighboring RANs whose signal strength is greater than the first threshold of the P Neighboring RANs.

[00395] It should be noted that the first threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00396] It should also be noted that when the Service RAN selects Neighboring M RANs from Neighboring P RANs based on the signal strength of each of the Neighboring P RANs, the Service RAN can first determine the signal strength of each of the Neighboring M RANs based on the signal strength of each of the Neighboring P RANs. Secondly, the Service RAN can determine the measurement information of each of the Neighboring M RANs based on the association relationships between the respective signal strengths of the Neighboring M RANs and the respective measurement information of the Neighboring M RANs. Then, the Service RAN can determine the attribute information of each of the Neighboring M RANs based on the association relationships between the respective measurement information of the Neighboring M RANs and the respective attribute information of the Neighboring M RANs. Finally, the Service RAN can determine the Neighboring M RANs based on the attribute information of each of the Neighboring M RANs.

[00397] In S407, the Service RAN sends the first information to the SF.

[00398] Consequently, the SF can receive the first information from the Service RAN. Petition 870250083541, dated 09 / 17 / 2025, page 72 / 313 66 / 126

[00399] The initial information may include attribute information for each of the neighboring M RANs.

[00400] In some embodiments, the initial information additionally includes measurement information for each of the Neighboring M RANs and the signal strength of each of the Neighboring M RANs.

[00401] There are association relationships between the respective measurement information of the neighboring M RANs and the respective attribute information of the neighboring M RANs, and there are association relationships between the respective signal strengths of the neighboring M RANs and the respective measurement information of the neighboring M RANs.

[00402] In some forms, the initial information may additionally include identification information for AMFs corresponding to the Neighboring M RANs, respectively.

[00403] Additionally, the Service RAN can send the initial information and the identification information of the detection task to the SF based on at least one of the following: SF identification information, SF instance information, and SF address information.

[00404] In S408, SF sends the first information.

[00405] N is a positive integer less than or equal to M.

[00406] It should be noted that N Neighboring RANs can be randomly selected by the SF from the M Neighboring RANs. Alternatively, N Neighboring RANs can be selected by the SF from the M Neighboring RANs according to Petition 870250083541, dated 09 / 17 / 2025, page 73 / 313 67 / 126 with the signal strength of each of the neighboring M RANs.

[00407] For example, SF can select the main Neighboring N RANs with the highest signal strength from the Neighboring M RANs.

[00408] For example, SF can select N Neighboring RANs whose signal strength is greater than the second threshold of the M Neighboring RANs.

[00409] It should be noted that the second threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00410] It should also be noted that when the SF selects N Neighboring RANs from M Neighboring RANs based on the signal strength of each of the M Neighboring RANs, the SF can first determine the signal strength of each of the N Neighboring RANs based on the signal strength of each of the M Neighboring RANs. Secondly, the SF can determine the measurement information of each of the N Neighboring RANs based on the association relationships between the respective signal strengths of the N Neighboring RANs and the respective measurement information of the N Neighboring RANs. Next, the SF can determine the attribute information of each of the N Neighboring RANs based on the association relationships between the respective measurement information of the N Neighboring RANs and the respective attribute information of the N Neighboring RANs. Finally, the SF can determine the N Neighboring RANs based on the attribute information of each of the N Neighboring RANs.

[00411] In S409, SF establishes a communication connection.

[00412] In some sports, SF can Petition 870250083541, dated 09 / 17 / 2025, page 74 / 313 68 / 126 establish the communication connection with the N Neighboring RANs according to the attribute information of each of the N Neighboring RANs, and the communication connection is used to obtain the result of performing the detection task.

[00413] By way of example, the SF can query attribute information of Neighboring RANs via NRF / AMF or locally stored information to establish a user plane connection. Alternatively, the SF can obtain identification information of an AMF corresponding to the Neighboring RANs by querying the NRF or locally stored information and perform the control plane interaction via the AMF. Alternatively, if the SF obtains the identification information of the AMF corresponding to the Neighboring RANs, the SF can retrieve relevant information from the corresponding Neighboring RANs of the AMF via a control plane, thus establishing a user plane connection with the Neighboring RAN or performing the control plane interaction via the AMF.

[00414] In S410a, SF sends the fifth request information to the EU.

[00415] Consequently, the EU can receive the fifth request information from the SF.

[00416] The fifth request information can be used to request the result of performing the detection task.

[00417] In some applications, the fifth application information may include at least one of the following:

[00418] detection task identification information;

[00420] a detection scenario / method when performing the detection task.

[00421] In S410b, SF sends the fifth request information to the Service RAN.

[00422] Consequently, the Service RAN can receive the fifth request information from the SF.

[00423] In S410c, SF sends the fifth request information to the neighboring N RANs.

[00424] Consequently, the neighboring N RANs can receive the fifth request information from the SF.

[00425] In some modalities, the fifth request information may include EU attribute information.

[00426] Additionally, EU attribute information may include EU identification and / or address information.

[00427] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00428] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00429] It is understood that the EU identification information in fifth request information is SUPI information, SUCI information, GPSI information and the like used for internal querying on the main network, as compared to third request information, whereas third request information does not impose such limitations. Petition 870250083541, dated 09 / 17 / 2025, page 76 / 313 70 / 126

[00430] It should also be noted that an order in which the SF sends the fifth request information to the UE, the SF sends the fifth request information to the Service RAN, and the SF sends the fifth request information to the N Neighboring RANs is not limited by the arrangements of this disclosure.

[00431] In S411, communication takes place between the Service RAN, the Neighboring N RANs and the UE.

[00432] Communication is used to obtain the result of performing the detection task.

[00433] It should be noted that communication is carried out between the Service RAN, the N Neighboring RANs and the UE, so that reference signals can be obtained by at least one of the Service RAN, the N Neighboring RANs and the UE, in this way, the reference signals can be measured.

[00434] By way of example, the Service RAN communicates with the UE and the N Neighboring RANs, so that the Service RAN can obtain reference signals sent by the UE RAN and the N Neighboring RANs and, in this way, can measure the reference signals.

[00435] In S412, the Service RAN determines the outcome of performing the detection task.

[00436] In some modes, if the Service RAN measures the reference signals sent by the UE and the N Neighboring RANs, the Service RAN may determine the outcome of performing the detection task based on the measurement result.

[00437] For example, the result of performing the detection task may be that detection data is generated. Petition 870250083541, dated 09 / 17 / 2025, p. 77 / 313 71 / 126

[00438] In S413, the Service RAN sends the fourth piece of information to the SF.

[00439] Consequently, the SF can receive the fourth Service RAN information.

[00440] The fourth piece of information includes the result of performing the detection task.

[00441] It should be noted that, in practical applications, the UE and / or the neighboring N RANs can determine the result of performing the detection task and send the result of performing the detection task to the SF.

[00442] It should also be noted that at least one of the Service RANs, the UE and the Neighboring N RANs may send the fourth information to the AMF and then the AMF forwards the fourth information to the SF.

[00443] In S414, SF sends the fifth piece of information to the consumer invoice.

[00444] The fifth piece of information includes the result of performing the detection task.

[00445] It should be noted that, in the embodiments of the present disclosure, the Service RAN may be a different RAN from the Neighboring RANs, and the Service RAN may be one of the RANs Neighboring RANs, and whether or not there is an inclusive relationship between the Service RAN and the Neighboring RANs depends on a specific application scenario, which is not limited by the terms of this disclosure.

[00446] Based on scenario #C, it may be necessary to select auxiliary RANs (i.e., Neighboring RANs) when detecting the UE, and the auxiliary RANs are used to assist the UE in performing the detection task. Additionally, it is necessary that the selected auxiliary RANs have the Petition 870250083541, dated 09 / 17 / 2025, page 78 / 313 72 / 126 capability to establish a communication connection (generally a user plane connection) with the SF, so that the SF can determine the corresponding auxiliary RANs. In embodiments of the present disclosure, the UE Service RAN queries the attribute information of the auxiliary RANs and reports the attribute information of the auxiliary RANs to the SF, so that the SF can obtain the attribute information of the auxiliary RANs.

[00447] In scenario no. D, EU reports assign information from each of the Neighboring RANs to the SF.

[00448] Figure 5 is a third detailed flowchart of a method for detecting UE provided by an embodiment of the present disclosure. As illustrated in Figure 5, after receiving the discovery request (i.e., initial request information) from the Neighboring RANs, the UE performs signal measurement, acquires attribute information from the Neighboring RANs from the Service RAN, and then reports the attribute information from the Neighboring RANs to the SF, and the SF makes a decision. The detailed flow of the method may include the following operations.

[00449] In S501, the consumer invoice sends the third-party request information to the SF.

[00450] Consequently, SF may receive third-party request information.

[00451] Third-party request information can be used to request that the EU obtain a detection task completion result.

[00452] It should be noted that the consumer NF may be at least one of AF, NEF and UE, or may be other network elements or devices, which is not limited by the purposes of this disclosure. Petition 870250083541, dated 09 / 17 / 2025, page 79 / 313 73 / 126

[00453] For example, the consumer NF can be the NEF, and the NEF can send third-party request information to the SF.

[00454] For example, the consumer NF can be the NEF and the AF. The AF can send third-party request information to the NEF, and the NEF can send third-party request information to the SF.

[00455] In some modes, the detection task may include at least one of:

[00456] a user execution action;

[00457] respiratory monitoring;

[00458] a speed of movement of the terminal device;

[00459] environmental imaging; and

[00460] monitoring of weather conditions.

[00461] In some modalities, the third-party request information may include EU attribute information.

[00462] Additionally, EU attribute information may include EU identification information and / or address information.

[00463] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00464] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00467] quality information needed to perform the detection task; and

[00468] a detection scenario / method when performing the detection task.

[00469] The quality information required to perform the detection task may be precision information necessary to perform the detection task, or it may be other information, which is not limited by the embodiments of the present disclosure.

[00470] The detection scenario / method when performing the detection task can be one of the following: single gNB detection, gNB-gNB detection, UE-gNB uplink detection, UE-gNB downlink detection, single UE detection, and UE-UE detection.

[00471] In the embodiments of the present disclosure, the detection scenario / method when performing the detection task mainly includes uplink detection of UEgNB and / or downlink detection of UE-gNB.

[00472] In S502, SF determines the UE attribute information.

[00473] It should be noted that the SF or other network elements (such as the NEF, etc.) can map the UE identification information, and the identification information is converted into SUPI information, SUCI information, GPSI information, etc., which can be used directly for internal querying within the main network.

[00474] For example, the SF can map the UE's identification information by consulting other Petition 870250083541, dated 09 / 17 / 2025, page 81 / 313 75 / 126 network elements (e.g., AMF / UDR / UDM) or by querying local information, thus obtaining SUPI information, SUCI information, GPSI information, and similar information for internal querying within the main network.

[00475] Note that the UE above is the target UE. After determining the UE attribute information, the SF can determine the Service RAN based on the UE attribute information. Alternatively, the SF can first determine the Service RAN attribute information and then determine the UE based on the Service RAN attribute information.

[00476] It should also be noted that, in the embodiments of the present disclosure, the target UE may be determined by SF, or may be determined by other network elements (such as the UE Service AMF or UDM, etc.), which is not limited by the embodiment of the present disclosure.

[00477] In S503, SF sends the first request information to the EU.

[00478] Consequently, the EU can receive the first request information from the SF.

[00479] The initial request information can be used to query attribute information for each of the neighboring M RANs, and the neighboring RANs can be used to assist the UE in performing the detection task.

[00480] M is a positive integer.

[00481] It should be noted that the initial request information may be referred to as an auxiliary RAN discovery request. Alternatively, the initial request information may also be referred to as a detection task request, and the task request. Petition 870250083541, dated 09 / 17 / 2025, page 82 / 313 The 76 / 126 detection carries indication information to indicate the discovery of auxiliary RANs. Alternatively, the initial request information may also be referred to as the detection task request, and the detection task request includes a selection of UE-gNB uplink detection and UE-gNB downlink detection as the detection scenario / method, so that the terminal device can implicitly know that it needs to discover the auxiliary RANs to perform the detection task.

[00482] In some embodiments, the attribute information of a Neighboring RAN includes identification information and / or address information of the Neighboring RAN.

[00483] In some applications, the initial application information may include at least one of the following:

[00484] detection task identification information;

[00489] Consequently, the EU can receive the SF's indication information.

[00490] The indication information is used to indicate the UE to consult attribute information from each of the neighboring M RANs based on the initial request information.

[00491] In S504, the UE performs signal measurement.

[00492] In some modes, the UE may determine the measurement information for each of the P RANs Petition 870250083541, dated 09 / 17 / 2025, page 83 / 313 77 / 126 Neighboring stations are measuring the downlink reference signals sent by neighboring PRANs.

[00493] There are association relationships between the respective measurement information of the neighboring P RANs and the respective attribute information of the neighboring P RANs.

[00494] Neighboring P RANs may include M Neighboring RANs and P is a positive integer greater than or equal to M.

[00495] For example, the measurement information of each of the Neighboring P RANs may have a one-to-one mapping relationship with the attribute information of each of the Neighboring P RANs.

[00496] In some modes, measurement information may include cell ID and / or TA ID.

[00497] In some modes, the UE can determine the signal strength of each of the neighboring P RANs by measuring the downlink reference signals sent by the neighboring P RANs.

[00498] There are association relationships between the respective signal intensities of neighboring PRANs and the respective measurement information of neighboring PRANs.

[00499] In S505, the UE sends the fourth request information to the Service RAN.

[00507] Consequently, the EU can receive third-party information from the Service RAN.

[00508] The third information includes the attribute information for each of the Neighboring P RANs.

[00509] In some modalities, the third information may additionally include identification information of AMFs corresponding to the Neighboring P RANs, respectively.

[00510] In some embodiments, the Service RAN may determine the attribute information of each of the Neighboring RANs P according to the measurement information of each of the Neighboring RANs P based on the association relationships between the respective measurement information of the Neighboring RANs P and the respective attribute information of the Neighboring RANs P.

[00511] In addition, the Service RAN can determine attribute information for each of the Neighboring PRANs based on measurement information from each of the Neighboring PRANs, locally stored neighboring cell information, neighboring base station information, and similar data.

[00512] In S507, the UE selects M Neighboring RANs. Petition 870250083541, dated 09 / 17 / 2025, page 85 / 313 79 / 126

[00513] It should be noted that the Neighboring M RANs can be randomly selected by the UE from the Neighboring P RANs. Alternatively, the Neighboring M RANs can be selected by the UE from the Neighboring P RANs according to the signal strength of each of the Neighboring P RANs.

[00514] For example, the UE can select the main neighboring M RANs with the highest signal strength from the neighboring P RANs.

[00515] For example, the UE can select neighboring M RANs whose signal strength is greater than the third threshold of neighboring P RANs.

[00516] It should be noted that the third threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00517] It should also be noted that when the UE selects Neighboring M RANs from Neighboring P RANs based on the signal strength of each of the Neighboring P RANs, the UE can first determine the signal strength of each of the Neighboring M RANs based on the signal strength of each of the Neighboring P RANs. Secondly, the UE can determine the measurement information of each of the Neighboring M RANs based on the association relationships between the respective signal strengths of the Neighboring M RANs and the respective measurement information of the Neighboring M RANs. Next, the UE can determine the attribute information of each of the Neighboring M RANs based on the association relationships between the respective measurement information of the Neighboring M RANs and the respective attribute information of the Neighboring M RANs. Finally, the UE can determine the Neighboring M RANs based Petition 870250083541, dated 09 / 17 / 2025, page 86 / 313 80 / 126 in the attribute information of each of the neighboring M RANs.

[00533] In some embodiments, the SF can establish the communication connection with the N Neighboring RANs according to the attribute information of each of the N Neighboring RANs, and the communication connection is used to obtain the result of performing the detection task.

[00534] By way of example, the SF can query attribute information of Neighboring RANs via NRF / AMF or locally stored information to establish a user plane connection. Alternatively, the SF can obtain identification information from an AMF corresponding to the Neighboring RANs by querying the NRF or locally stored information and perform control plane interaction via the AMF. Alternatively, if the SF obtains the identification information from the AMF corresponding to the Neighboring RANs, the SF can retrieve relevant information from the corresponding Neighboring RANs from the AMF via a control plane, thus establishing a user plane connection with the Neighboring RANs or performing control plane interaction via the AMF.

Additionally, the selected auxiliary RANs must have the capability to establish a communication connection (generally a user plane connection) with the SF, so that the SF can determine the corresponding auxiliary RANs. In the embodiments of this disclosure, the UE queries the attribute information of the auxiliary RANs from the Service RAN and reports the attribute information of the auxiliary RANs to the SF, so that the SF can obtain the attribute information of the auxiliary RANs.

[00573] It should be noted that the consumer NF can be at least one of AF, NEF and UE, or it can be other network elements or devices, which is not limited by Petition 870250083541, dated 09 / 17 / 2025, page 93 / 313 87 / 126 modalities of the present disclosure.

[00574] For example, the consumer invoice can be the NEF, and the NEF can send third-party request information to the SF.

[00575] For example, the consumer invoice can be the NEF and the AF. The AF can send third-party request information to the NEF, and the NEF can send third-party request information to the SF.

[00576] In some modes, the detection task may include at least one of:

[00578] respiratory monitoring;

[00579] a speed of movement of the terminal device;

[00580] environmental imaging; and

[00581] monitoring of weather conditions.

[00582] In some modalities, the third-party request information may include EU attribute information.

[00583] Additionally, EU attribute information may include EU identification information and / or address information.

[00584] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00585] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00586] In some applications, the third-party application information may include at least one of the following: Petition 870250083541, dated 09 / 17 / 2025, page 94 / 313 88 / 126

[00587] detection task identification information;

[00588] quality information needed to perform the detection task; and

[00589] a detection scenario / method when performing the detection task.

[00590] The quality information required to perform the detection task may be precision information necessary to perform the detection task, or it may be other information, which is not limited by the embodiments of the present disclosure.

[00591] The detection scenario / method when performing the detection task can be one of the following: single gNB detection, gNB-gNB detection, UE-gNB uplink detection, UE-gNB downlink detection, single UE detection, and UE-UE detection.

[00592] In the embodiments of the present disclosure, the detection scenario / method when performing the detection task mainly includes UEgNB uplink detection and / or UE-gNB downlink detection.

[00593] In S602, SF determines the UE attribute information.

[00594] It should be noted that the SF or other network elements (such as the NEF, etc.) can map the UE identification information, and the identification information is converted into SUPI information, SUCI information, GPSI information, etc., which can be used directly for internal querying within the main network.

[00595] For example, SF can map Petition 870250083541, dated 09 / 17 / 2025, page 95 / 313 89 / 126 the identification information of the UE by consulting other elements of the network (e.g. AMF / UDR / UDM) or by consulting local information, thus obtaining SUPI information, SUCI information, GPSI information and the like for internal consultation within the main network.

[00596] Note that the UE above is the target UE. After determining the UE attribute information, the SF can determine the Service RAN based on the UE attribute information. Alternatively, the SF can first determine the Service RAN attribute information and then determine the UE based on the Service RAN attribute information.

[00597] It should also be noted that, in the embodiments of the present disclosure, the target UE may be determined by SF, or may be determined by other network elements (such as the UE Service AMF or UDM, etc.), which is not limited by the embodiment of the present disclosure.

[00598] In S603, SF sends the first request information to the EU.

[00599] Consequently, the EU can receive the first request information from the SF.

[00600] The initial request information can be used to query attribute information for each of the neighboring M RANs, and the neighboring RANs can be used to assist the UE in performing the detection task.

[00601] M is a positive integer.

[00602] It should be noted that the initial request information may be referred to as an auxiliary RAN discovery request. Alternatively, the initial request information may also be referred to as Petition 870250083541, dated 09 / 17 / 2025, page 96 / 313 90 / 126 detection task request, and the detection task request carries indication information to indicate the discovery of auxiliary RANs. Alternatively, the first request information may also be referred to as a detection task request, and the detection task request includes a selection of UE-gNB uplink detection and UE-gNB downlink detection as the detection scenario / way, so that the terminal device can implicitly know that it needs to discover the auxiliary RANs to perform the detection task.

[00603] In some embodiments, the attribute information of a Neighboring RAN includes identification information and / or address information of the Neighboring RAN.

[00604] In some applications, the initial application information may include at least one of the following:

[00605] identification information for the detection task;

[00606] SF identification information;

[00607] SF instance information; or

[00608] SF address information.

[00609] In some modalities, the SF may also send nomination information to the EU.

[00610] Consequently, the EU can receive the SF's indication information.

[00611] The indication information is used to indicate the UE to consult attribute information from each of the neighboring M RANs based on the initial request information.

[00612] In S604, the UE performs signal measurement.

[00613] In some modalities, the EU may Petition 870250083541, dated 09 / 17 / 2025, page 97 / 313 91 / 126 determine the measurement information of each of the neighboring M RANs by measuring the downlink reference signals sent by the neighboring M RANs.

[00614] There are association relationships between the respective measurement information of the neighboring M RANs and the respective attribute information of the neighboring M RANs.

[00615] For example, the measurement information of each of the Neighboring M RANs may have a one-to-one mapping relationship with the attribute information of each of the Neighboring M RANs.

[00616] In some modes, measurement information may include cell ID and / or TA ID.

[00617] In some modes, the UE can determine the signal strength of each of the neighboring M RANs by measuring the downlink reference signals sent by the neighboring M RANs.

[00618] There are association relationships between the respective signal intensities of the neighboring M RANs and the respective measurement information of the neighboring M RANs.

[00619] In S605, the EU sends the first information to the SF.

[00620] Consequently, the SF can receive the first information from the EU.

[00621] The initial information may include measurement information for each of the neighboring M RANs.

[00622] Additionally, the initial information may also include the signal strength of each of the neighboring M RANs.

[00623] In S606, SF sends the second request information to the Service RAN. Petition 870250083541, dated 09 / 17 / 2025, page 98 / 313 92 / 126

[00624] Consequently, the Service RAN can receive the second request information from the SF.

[00625] The second request information is used to query the attribute information of each of the Neighboring RANs M, and the second request information includes the measurement information of each of the Neighboring RANs M.

[00626] In some embodiments, the Service RAN may determine the attribute information of each of the Neighboring RANs M according to the measurement information of each of the Neighboring RANs M based on the association relationships between the respective measurement information of the Neighboring RANs M and the respective attribute information of the Neighboring RANs M.

[00627] Note that the SF can query attribute information for each of the Neighboring M RANs via the Service RAN, or the SF can query attribute information for each of the Neighboring M RANs via a UE Service AMF, a UDR, another SF, and context information stored locally by the SF.

[00628] In S607, the Service RAN sends the second piece of information to the SF.

[00629] Consequently, the SF receives the second Service RAN information.

[00630] The second set of information includes the attribute information for each of the neighboring M RANs.

[00631] In S608, the SF selects N Neighboring RANs.

[00632] N is a positive integer less than or equal to M.

[00633] It should be noted that N Neighboring RANs may Petition 870250083541, dated 09 / 17 / 2025, page 99 / 313 93 / 126 can be randomly selected by the SF from the neighboring M RANs. Alternatively, N neighboring RANs can be selected by the SF from the neighboring M RANs according to the signal strength of each of the neighboring M RANs.

[00634] For example, SF can select the main Neighboring N RANs with the highest signal strength from the Neighboring M RANs.

[00635] For example, SF can select N Neighboring RANs whose signal strength is greater than the second threshold of the M Neighboring RANs.

[00636] It should be noted that the second threshold may be a predefined parameter value or a parameter value defined in another way, which is not limited by the modalities of the present disclosure.

[00637] It should also be noted that when the SF selects N Neighboring RANs from M Neighboring RANs based on the signal strength of each of the M Neighboring RANs, the SF can first determine the signal strength of each of the N Neighboring RANs based on the signal strength of each of the M Neighboring RANs. Secondly, the SF can determine the measurement information of each of the N Neighboring RANs based on the association relationships between the respective signal strengths of the N Neighboring RANs and the respective measurement information of the N Neighboring RANs. Next, the SF can determine the attribute information of each of the N Neighboring RANs based on the association relationships between the respective measurement information of the N Neighboring RANs and the respective attribute information of the N Neighboring RANs. Finally, the SF can determine the N Neighboring RANs based on the attribute information of each of the N Neighboring RANs. Petition 870250083541, dated 09 / 17 / 2025, page 100 / 313 94 / 126

[00638] In S609, SF establishes a communication connection.

[00639] In some embodiments, the SF can establish the communication connection with the N Neighboring RANs according to the attribute information of each of the N Neighboring RANs, and the communication connection is used to obtain the result of performing the detection task.

[00640] For example, the SF can query attribute information from Neighboring RANs via NRF / AMF or locally stored information to establish a user plane connection. Alternatively, the SF can obtain identification information from an AMF corresponding to the Neighboring RANs by querying the NRF or locally stored information and perform the control plane interaction via the AMF.

[00641] In S610a, SF sends the fifth request information to the EU.

[00642] Consequently, the EU can receive the fifth request information from the SF.

[00643] The fifth request information can be used to request the result of performing the detection task.

[00644] In some applications, the fifth application information may include at least one of the following:

[00645] identification information for the detection task;

[00646] quality information needed to perform the detection task; and

[00647] a detection scenario / method when performing the detection task. Petition 870250083541, dated 09 / 17 / 2025, pp. 101 / 313 95 / 126

[00648] In S610b, SF sends the fifth request information to the Service RAN.

[00649] Consequently, the Service RAN can receive the fifth request information from the SF.

[00650] In S610c, SF sends the fifth request information to the neighboring N RANs.

[00651] Consequently, the neighboring N RANs can receive the fifth request information from the SF.

[00652] In some modalities, the fifth request information may include EU attribute information.

[00653] Additionally, EU attribute information may include EU identification information and / or address information.

[00654] It should be noted that UE identification information may include at least one of the following: SUPI information, SUCI information and GPSI information.

[00655] It should also be noted that EU address information may include IP address information and / or MAC address information.

[00656] It is understood that the EU identification information in fifth request information is SUPI information, SUCI information, GPSI information and the like used for internal consultation on the main network, as compared to third request information, whereas third request information does not impose such limitations.

[00657] It should also be noted that in an order in which SF sends the fifth request information to the EU, SF sends the fifth request information to the Petition 870250083541, dated 09 / 17 / 2025, page 102 / 313 96 / 126 The Service RAN, and the SF sends the fifth request information to the Neighboring N RANs, is not limited by the terms of this disclosure.

[00658] In S611, communication takes place between the Service RAN, the Neighboring RANs and the UE.

[00659] Communication is used to obtain the result of performing the detection task.

[00660] It should be noted that communication is carried out between the Service RAN, the N Neighboring RANs and the UE, so that reference signals can be obtained by at least one of the Service RAN, the N Neighboring RANs and the UE, in this way, the reference signals can be measured.

[00661] By way of example, the neighboring RAN1 communicates with the UE, N-1 Neighboring RANs different from the neighboring RAN1 and the Service RAN, so that the neighboring RAN1 can obtain reference signals sent by the UE, the N-1 Neighboring RANs and the Service RAN and, in this way, can measure the reference signals.

[00662] The neighboring RAN1 is one of the neighboring RANs.

[00663] In S612, Neighboring RANs determine the outcome of performing the detection task.

[00664] For example, the neighboring RAN1 can determine the outcome of performing the detection task.

[00665] In some modes, if the neighboring RAN1 measures the reference signals sent by the UE, N-1 Neighboring RANs other than the neighboring RAN1 and the Service RAN, the neighboring RAN1 can determine the outcome of performing the detection task based on the measurement result.

[00666] For example, the result of Petition 870250083541, dated 09 / 17 / 2025, pp. 103 / 313 97 / 126 completion of the detection task may result in the generation of detection data.

[00667] In S613, the Neighboring RANs send the fourth piece of information to SF.

[00668] For example, the neighboring RAN1 can send the fourth piece of information to the SF.

[00669] Consequently, SF can receive the fourth information from the neighboring RAN1.

[00670] The fourth piece of information includes the result of performing the detection task.

[00671] It should be noted that, in practical applications, the UE and / or the Service RAN may determine the result of performing the detection task and send the result of performing the detection task to the SF.

[00672] It should also be noted that at least one of the Service RANs, the UE and the Neighboring N RANs may send the fourth information to the AMF and then the AMF forwards the fourth information to the SF.

[00673] In S614, SF sends the fifth piece of information to the consumer's NF.

[00674] The fifth piece of information includes the result of performing the detection task.

[00675] It should be noted that, in the embodiments of the present disclosure, the Service RAN may be a different RAN from the Neighboring RANs, and the Service RAN may be one of the RANs Neighboring RANs, and whether or not there is an inclusive relationship between the Service RAN and the Neighboring RANs depends on a specific application scenario, which is not limited by the terms of this disclosure.

[00676] Based on scenario #E, it may be Petition 870250083541, dated 09 / 17 / 2025, page 104 / 313 98 / 126 requires selecting auxiliary RANs (i.e., Neighboring RANs) when detecting the UE, and the auxiliary RANs are used to assist the UE in performing the detection task. Additionally, the selected auxiliary RANs must have the capability to establish a communication connection (generally a user plane connection) with the SF, so that the SF can determine the corresponding auxiliary RANs. In the embodiments of this disclosure, the UE reports the measurement information of the auxiliary RANs to the SF, and the SF queries the attribute information of the auxiliary RANs based on the measurement information of the auxiliary RANs, so that the SF can obtain the attribute information of the auxiliary RANs.

[00677] It should be understood that, in the embodiments of the present disclosure, the SF may send the first request information (i.e., trigger information) to the UE to request that the UE query the attribute information of the auxiliary RANs, and the UE may perform signal measurement based on the first request information, so that the SF may ultimately obtain the attribute information of the auxiliary RANs. It can be understood that the SF may send the fifth request information (i.e., trigger information) directly to the UE to request the obtaining of the result of performing the detection task, and the UE may perform signal measurement based on the fifth request information, so that the SF may ultimately obtain the attribute information of the auxiliary RANs.
