[0030] The solution of the technique in the present disclosure will be described below together with the accompanying drawings.

[0031] Figure 1 illustrates a wireless communication system 100 to which the embodiments of the present disclosure are applicable. The wireless communication system 100 may include a network device 110 and a user equipment (UE) 120. The network device 110 may communicate with the UE 120. The network device 110 may provide communication coverage for a geographic area. Petition 870250085835, dated 09 / 23 / 2025, page 12 / 150 6 / 51 specifically and can communicate with UE 120 located within the coverage area. UE 120 can access a network (e.g., a wireless network) through network device 110.

[0032] Figure 1 illustrates by way of example a network device and two UEs. Optionally, the 100 wireless communication system may include a plurality of network devices, and there may be another number of terminal devices within the coverage area of ​​each network device, which is not limited in the embodiments of the present disclosure. Optionally, the 100 wireless communication system may additionally include other network entities, such as a network controller and a mobility management entity, which are not limited in the embodiments of the present disclosure.

[0033] It should be understood that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a 5th generation (5G) or new radio (NR) system, a long-term evolution (LTE) system, an LTE frequency division duplexing (FDD) system, and an LTE time division duplexing (TDD) system. The technical solutions provided in the present disclosure can additionally be applied to future communication systems, such as a 6th generation mobile communication system or a satellite communication system.

[0034] The UE in the embodiments of the present disclosure may also be referred to as a terminal device, an access terminal, a user unit, a user station, a mobile platform, a mobile station (MS), a mobile terminal (MT), a remote station, a terminal Petition 870250085835, dated 09 / 23 / 2025, page 13 / 150 7 / 51 remote, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent or a user appliance. The EU in the embodiments of this disclosure may refer to a device that provides voice and / or data connectivity to a user, which can be used to connect people, objects and machines, such as a portable device or in-vehicle device with wireless connection functions.The UE in the embodiments of the present disclosure may be a mobile phone, a tablet, a laptop computer, a portable computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart network, a wireless terminal in transport security, a wireless terminal in a smart city, a wireless terminal in a smart home, or the like. Optionally, the UE may be configured to act as a base station. For example, the UE may act as a scheduling entity that provides side-link signals between UEs in V2X or D2D. For example, a mobile phone and a car communicate with each other using side-link signals.A cell phone and a smart home device communicate with each other without relaying communication signals through the base station.

[0035] The network device in the embodiments of this disclosure may be a device for communication with the EU, and the network device may also be referred to as an access network device or a network device. Petition 870250085835, dated 09 / 23 / 2025, page 14 / 150 8 / 51 Wireless access. For example, the network device may be a base station. The network device in the embodiments of the present disclosure may refer to a radio access network (RAN) node (or device) that accesses the UE to a wireless network. The base station may be generalized to encompass the following names or be replaced by the following names, such as: NodeB, evolved base station (evolved NodeB, eNB), next-generation base station (next-generation NodeB, gNB), relay station, access point, transmit and receive point (TRP), transmission point (TP), master station MeNB, secondary station (SeNB), multi-pattern radio node (MSR), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), and positioning node.A base station can be a macro base station, a micro base station, a relay node, a donor node, or an analog, or a combination thereof.

[0036] In some embodiments, the network device may be fixed or mobile. For example, a helicopter or drone may be configured to act as a mobile network device, and one or more cells may move based on the location of the mobile network device. In other examples, the helicopter or drone may be configured to function as a communication device with another network device. In some embodiments, the network device may refer to a CU or a DU, or the network device may include a CU and a DU, or the network device Petition 870250085835, dated 09 / 23 / 2025, p. 15 / 150 9 / 51 may additionally include an AAU.

[0037] It should be understood that the network device can be deployed on land, including indoors or outdoors, in a handheld computer or vehicle; the network device can also be deployed in water; and the network device can also be deployed in aircraft, balloons, and satellites in the air. The scenarios in which the network device is located are not limited to the embodiments of this disclosure.

[0038] It should also be understood that all or part of the network device and UE functions in the present disclosure may also be implemented by software functions implemented in hardware or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0039] Figure 2 is a 5G system architecture diagram, which includes: a network slice selection function (NSSF), an authentication server function (AUSF), a unified data management (UDM), an access and mobility management function (AMF), a session management function (SMF), a policy control function (PCF), an application function (AF), a UE, a radio access network (RAN) network element, a user plane function (UPF) network element, a data network (DN), and other network elements.

[0040] As illustrated in Figure 2, the UE can establish an access layer connection with the access network (AN) via a Uu interface, to exchange access layer messages and transmit wireless data. The UE can establish a non-access layer connection. Petition 870250085835, dated 09 / 23 / 2025, page 16 / 150 10 / 51 (NAS) communicates with the AMF via an N1 interface to exchange NAS messages. The AMF is a mobility management function on the core network, and the SMF is a session management function on the core network. In addition to managing UE mobility, the AMF is also responsible for forwarding session management-related messages between the UE and the SMF. The PCF is a policy management function on the core network and is responsible for formulating policies related to UE mobility management, session management, and billing. The UPF is a user plane function on the core network, where the UPF can transmit data with external data networks via an N6 interface and can transmit data with the AN via an N3 interface.

[0041] Existing cellular networks, including 5G networks, are generally used only for communications. But in fact, the electromagnetic radio wave signals used by cellular networks can not only be used for wireless data transmission and communication, but also have environmental sensing capabilities. For example, electromagnetic radio wave signals can detect user actions, gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, weather monitoring, or similar. Therefore, in cellular networks, electromagnetic radio wave signals can be used not only for communication and data transmission, but also for obtaining sensing information.

[0042] Discussions are currently underway to provide support for detection functions (e.g., Petition 870250085835, dated 09 / 23 / 2025, page 17 / 150 11 / 51 integrated detection and communication) in networks beyond 5G (B5G) and to support detection functions in 3rd generation partnership project (3GPP) networks, by adding a detection control network element (a detection function, SF) and the corresponding process.

[0043] Figure 3 is a flowchart of a possible control method for an access network device or UE to perform a UE-level detection operation (per UE).For example, as illustrated in Figure 3, in the case where an application (e.g., an AF) transmits a detection request from a target UE to the 3GPP network's main network (e.g., a network exposure function (NEF)), the main network can select a correct access network device or another UE via the detection control network element or a mobility management network element (e.g., the AMF) and transmit a detection instruction to the access network device (e.g., step 4 in Figure 3) or the target UE (e.g., step 7 in Figure 3), to trigger the ability of the access network device or the target UE to perform wireless measurements related to the detection task, initiate the measurement of the detection information (e.g., steps 5 and 8 in Figure 3), and generate a detection result (e.g., steps 6 and 9 in Figure 3).

[0044] The main wireless detection scenarios for integrated detection and communication (which may be referred to as ISAC for short) are as follows:

[0045] 1) base station echo detection link (single gNB detection): a base station that transmits a detection signal and receives an echo signal; Petition 870250085835, dated 09 / 23 / 2025, p. 18 / 150 12 / 51

[0046] 2) detection link between base stations (gNB-gNB detection): a base station B that receives a detection signal transmitted from a base station A;

[0047] 3) Air Interface Uplink Detection (UE-gNB Uplink Detection): a base station that receives a detection signal transmitted from a terminal;

[0048] 4) Air Interface Downlink Detection (UE-gNB Downlink Detection): a terminal that receives a detection signal transmitted from a base station;

[0049] 5) Terminal echo detection link (single UE detection): a terminal that transmits a detection signal and receives an echo signal; and

[0050] 6) Terminal-to-terminal detection link (UE-UE detection): a terminal B receiving a detection signal transmitted from a terminal A.

[0051] In the initial stages of integrated B5G detection and communication, existing air interface signals are considered, as far as possible, to be reused to perform detection operations without introducing much air interface enhancement; and the complexity of full duplex implementation, to allow collaborative detection between terminal devices and / or base stations, is a priority.

[0052] For UE-level detection, a detection target is usually a given UE or objects and environments surrounding the UE. Since it is difficult to implement autonomous full-duplex UE transmission and reception, additional UE nodes may be needed to assist in Petition 870250085835, dated 09 / 23 / 2025, p. 19 / 150 13 / 51 tasks of detecting a transmission and a reception.

[0053] It can be observed from the above modalities that, in a case where a detection task is performed on a target user equipment (TUE) in a side link (SL), another TUE may be required to perform the assistance.

[0054] In side linking, the UE can discover (and select) other SL UE nodes (side link UE discovery and selection) in several ways. Two common models will be introduced below.

[0055] Model for discovering model A (I am here).

[0056] The model defines two functions for UEs that participate in discovery: (1) Announcement UE, which can announce certain information (for example, certain information can be carried in an announcement message illustrated in Figure 4), which can be used by nearby UEs with discovery permissions; (2) Monitoring UE, which monitors certain information of interest around the announcement UE.

[0057] In this model, the advertising UE can transmit an advertising message at a predefined discovery interval, and the monitoring UE interested in the advertising message can read and process the discovery message. This model is equivalent to I'm here, since the advertising UE can transmit information about itself.

[0058] Model for discovery model B (Who's there? / Are you there?).

[0059] The model defines two functions for UEs that Petition 870250085835, dated 09 / 23 / 2025, page 20 / 150 14 / 51 participate in the discovery: (1) Discovery UE, which can transmit a request message that includes certain information about what it is interested in discovering; (2) the discovered UE, which is a UE that receives the request message, can respond with some information related to the request message transmitted by the discovering UE.

[0060] This is equivalent to who's there / are you there because the discoverer UE transmits information that a response is expected from another UE. The information may be a proximity service application (ProSe) identifier corresponding to a group, to which group members may respond.

[0061] It can be observed that currently in the side link, the target UE can discover another SL UE in several ways, but it is unclear how to perform the detection task with the help of another UE. Therefore, how to perform the detection task with the help of another UE has become a problem of the technique that needs to be solved urgently.

[0062] Furthermore, the above side-link UE discovery and selection model is applicable only to the discovering UE that obtains information from the discovered UE (or to the advertising UE that obtains information from the monitoring equipment), but for the execution of a final detection task, both the discovering UE and the advertising UE are required to establish a connection to the network (e.g., the SF in Figure 3), and the discovering UE information obtained by the advertising UE via the general side link does not include a permanent subscription identifier (SUPI) and other UE identifier (ID) information that may be Petition 870250085835, dated 09 / 23 / 2025, page 21 / 150 15 / 51 recognized by the main network. Even if the information is reported to the network, the network may not have the ability to find the corresponding UE and cannot interact with the detection task. Therefore, how to enable another UE in the detection task to establish a connection with the network is another problem of the technique that must be solved.

[0063] To solve one or more of the above technical problems, the present disclosure proposes a method of communication and a communication apparatus. The embodiments of the present disclosure are described in detail below with reference to Figures 6 to 9.

[0064] Figure 6 is an illustrative flowchart of a communication method provided in the embodiment of the present disclosure. The method 600 illustrated in Figure 6 may include steps S610 and S620, which are specifically as follows.

[0065] In the S610, a first terminal device transmits the first information to a second terminal device.

[0066] Here, the initial information can be used to request that the second terminal device serve as another UE that performs the first detection task. Optionally, the first detection task can be a detection task for the first terminal device. Optionally, the other UE can refer to another SL UE that assists the first terminal device in performing the first detection task. The other UE can also be called an assistant UE.

[0067] Optionally, the initial information may include one or more of the following: identification information Petition 870250085835, dated 09 / 23 / 2025, p. 22 / 150 16 / 51 of the first detection task, identifier information for a detection request, a detection type, a detection quality requirement, and identifier information for a first network element.

[0068] Here, the identifier information for the detection request may be identifier information corresponding to the second piece of information below.

[0069] The type of detection may include one or more of the following: intrusion monitoring, target positioning, motion capture, speed prediction, trajectory prediction, and channel processing information reporting (e.g., location information, Doppler frequency change information, point cloud information).

[0070] The quality requirement for detection may include information such as detection accuracy, reporting frequency, and false alarm rate.

[0071] The first network element can be a network element used for a discovery service. For example, the first network element can be a newly added network element, such as a discovery control network element (discovery function, SF) newly added to a 5G system; alternatively, the first network element can be an existing network element, such as LMF (location management function), AMF. The identifier information of the first network element can include device identifier (ID) information of the first network element, instance information of the first network element within a system (e.g., the system Petition 870250085835, dated 09 / 23 / 2025, page 23 / 150 17 / 51 5G) and / or address information of the first network element.

[0072] Optionally, the initial information may include identifier (ID) information for the first terminal device.

[0073] Optionally, the initial information can be carried in a detection request message. The detection request message can be an announcement message or a request message transmitted via a PC5 interface in SL, or it can be other messages (such as a newly defined detection request message).

[0074] Optionally, the initial information can be transmitted from the first terminal device to one or more terminal devices around the first terminal device (the second terminal device can be one of the one or more terminal devices). Optionally, the initial information can be transmitted in a multicast or broadcast manner.

[0075] For example, the first terminal device can first discover another SL UE using the model for discovery model A or the model for discovery model B and then transmit the first information to the other discovered SL UE using the discovery request message.

[0076] As another example, the first terminal device can transmit the first information to the surrounding terminal devices using the detection request message directly. Optionally, in this case, the request message of Petition 870250085835, dated 09 / 23 / 2025, page 24 / 150 18 / 51 detection may include the meaning of discovering another UE from SL and requesting that another UE that performs the first detection task perform the detection.

[0077] In embodiments of the present disclosure, the first terminal device transmits the first information to the second terminal device, which facilitates the use of the second terminal device as another UE that performs the first detection task, so as to facilitate the performance of the detection task with the help of the second terminal device.

[0078] In some embodiments, before performing S610, method 600 may include step S620, which is as follows.

[0079] In S620, a first network element transmits the second information to a first terminal device.

[0080] The second piece of information can be used to indicate the first terminal device to discover another UE with the capability to perform the first detection task.

[0081] Optionally, the second information may include one or more of the following: first indication information, first detection task identifier information, a detection request identifier information, a detection method, a detection type, a detection quality requirement, and a first network element identifier information. Here, the first indication information may indicate that the first terminal device discovers another UE used to perform the first detection task. Petition 870250085835, dated 09 / 23 / 2025, p. 25 / 150 19 / 51

[0082] In the present revelation, the second piece of information can be discovered in several ways, which are specifically as follows.

[0083] In some embodiments, the second information may be explicitly indicated. For example, the second information itself may be the request information used to request that the first terminal device discover another UE used to perform the first detection task; alternatively, the second information may include request information, such as the first indication information above.

[0084] In some embodiments, the second information may be indicated implicitly. For example, in the case where the second information includes one or more of the following: the identifier information of the first detection task, the identifier information of the detection request, the detection mode, the detection type, the detection quality requirement, and the identification information of the first network element, the second information may indicate a request for the first terminal device to discover another UE used to perform the first detection task. Here, the detection method may include an indication of a manner in which the first terminal device performs the transmission and another UE (e.g., the second terminal device) performs the reception, and may also include an indication of another UE as transmitter or receiver.

[0085] In the present disclosure, a connection between another UE and the network can be established through various methods, which are described respectively below in combination. Petition 870250085835, dated 09 / 23 / 2025, page 26 / 150 20 / 51 with Figures 7 to 9 (the first network element in Figures 7 to 9 takes the SF as an example).

[0086] Method 1: The first terminal device transmits identification information from the first network element to the second terminal device. After receiving the first information, the second terminal device actively establishes a connection with the first network element based on the first network element's identifier information. Method 1 is specifically described below.

[0087] The first terminal device can transmit the first information to the second terminal device corresponding to the first terminal device. Optionally, the first information can include identifier information for the first network element.

[0088] Optionally, the second terminal device can actively establish a connection with the first network element based on the first information.

[0089] Optionally, after establishing a connection with the first network element, the second terminal device can interact with the first network element. For example, the second terminal device can transmit sixth information to the first network element.

[0090] Optionally, the sixth piece of information can be used to indicate that the second terminal device has the capability to perform the first detection task. Optionally, the sixth piece of information can include Petition 870250085835, dated 09 / 23 / 2025, page 27 / 150 21 / 51 one or more of the following: identification information of the first detection task, identifier information of a detection request, and identifier information of the first terminal device.

[0091] Optionally, the first network element can receive the sixth information transmitted from one or more terminal devices (the second terminal device can be one of the one or more terminal devices) and determine another UE to perform the first detection task based on the sixth information received.

[0092] A specific implementation process of method 1 is described below in conjunction with Figure 7. In Figure 7, after receiving a UE-level detection request message and discovering UE1, the SF can transmit a discovery request message to UE1. UE1 can carry detection method information from a current detection task and the SF identifier information in the detection request message transmitted to UE2 around UE1 itself. Subsequently, UE2 can establish a connection with the SF and notify it. In this case, the SF can make subsequent selections of another UE.

[0093] As illustrated in Figure 7, method 700 may include steps S710 to S790, which are specifically as follows.

[0094] In S710, a consumer NF transmits a detection request message to the SF.

[0095] A consumer NF can be a core network element, such as AMF, NEF, or an application server, such as AF or UE. Petition 870250085835, dated 09 / 23 / 2025, p. 28 / 150 22 / 51

[0096] The detection request message may include information about a target UE (e.g., target UE ID information), the detection request may additionally include a requested detection method and / or a requested detection service type, and the detection request may additionally include quality information required for a detection service, such as accuracy.

[0097] Target EU information may include one or more of the following:

[0098] a target UE permanent signature identifier (SUPI), target UE hidden signature identifier (SUCI), target UE generic public signature identifier (GPSI), or other target UE information; and

[0099] Target EU address information (IP address, MAC address or similar).

[00100] Optionally, the SF or other network elements (e.g., the NEF) can map the target UE information to convert the target UE information into ID information (e.g., the SUPI) that can be used directly for querying on the core network.

[00101] In S720, SF queries UE1 based on target UE information (UE1 may be the first terminal device in the above modes).

[00102] Specifically, SF can discover UE1 by querying other network elements, such as AMF, a unified data repository (UDR), UDM, or by querying local information.

[00103] In S730, SF transmits a discovery request message to UE1. Petition 870250085835, dated 09 / 23 / 2025, page 29 / 150 23 / 51

[00104] The discovery request message may include the second piece of information in the above modalities.

[00105] The SF transmits the discovery request message to UE1 based on the detection request message, which may include information indicating the assisting UE to discover. Optionally, the detection request message may additionally include task / detection request identification information, the detection method (such as how UE A performs the transmission and UE B performs the reception; specifically, the detection request message may additionally include an indication of the assisting UE as transmitter or receiver), the detection type, the detection quality requirement or similar, and may additionally include SF ID information (e.g., SF device ID information, instance information within the 5GC, SF address information).

[00106] The detection type may include intrusion monitoring, target positioning, motion capture, speed / trajectory prediction, or similar, and the detection type may also be specific processing information from the request reporting channel (position information, Doppler frequency change information, point cloud information, or similar). The detection quality requirement may include information such as detection accuracy information, reporting frequency, and false alarm rate.

[00107] In S740, UE1 transmits a detection request message to UE2.

[00108] Detection request message Petition 870250085835, dated 09 / 23 / 2025, page 30 / 150 24 / 51 may include the initial information in the above modalities.

[00109] For example, after receiving the discovery request message transmitted from the SF, UE1 can transmit the detection request message to UE2 surrounding UE1 via SL. The detection request message can include detection task ID information, discovery request message ID information (which is consistent with that transmitted from the SF), the detection type, the detection quality requirement, or similar. The detection request message can additionally include the SF ID information and, optionally, the detection request message can also include more ID information from UE1 itself.

[00110] Here, UE1 transmits the detection request message to UE2 surrounding UE1 and may reuse an announcement message or a request message transmitted by the PC5 interface in the current SL and add information carried by the detection request message (e.g., initial information); UE1 may also first discover another SL UE via the model for discovery model A or the model for discovery model B and then initiate a request to another discovered SL UE via the detection request message; UE1 may also directly use a newly defined SL detection request message to transmit the detection request message, and the SL detection request message may be different from the existing request message but may include the meaning of both discovering the SL UE and requesting that another UE perform the detection. After receiving the Petition 870250085835, dated 09 / 23 / 2025, p. 31 / 150 25 / 51 message, UE2 around UE1 can simultaneously respond to UE1 with an SL UE discovery response and transmit a detection accomplishment response as another UE to SF.

[00111] In S750, UE2 establishes a connection with SF.

[00112] After receiving the detection request message transmitted from UE1, UE2 can determine that UE2 can perform the detection task as another UE based on UE2's own detection capabilities and detection requirements, and establish the connection with the SF via SF ID information. Specifically, a session can be established via SF user plane address information, or signaling interaction is performed via control plane signaling based on SF ID information.

[00113] In S760, UE2 reports a notification message to aSF.

[00114] The notification message may include the sixth piece of information in the above modalities.

[00115] The notification message may contain the detection task ID information and the discovery request message ID information (which is consistent with that transmitted from SF in S730). Optionally, the notification message may additionally include UE1 ID information and similar information.

[00116] In S770, SF selects another UE that performs the detection task.

[00117] SF obtains information from several selectable UEs based on reported notification messages Petition 870250085835, dated 09 / 23 / 2025, p. 32 / 150 26 / 51 for multiple UE2s and selects another UE.

[00118] On S780, SF transmits a detection task request message to UE1.

[00119] In the S790, the SF transmits a detection task request message to the selected UE2, which may be different from the detection request transmitted to UE1.

[00120] In the present disclosure, the detection requirement and SF ID information are carried in the detection request message transmitted from UE1 to the UEs around UE1, to allow the UEs around UE1 to know if they can support the detection task and know how to establish a connection with the SF and report that they can complete the detection task like another UE.

[00121] Method 2: The first terminal device selects the second terminal device as another UE that performs the first detection task and transmits the identifier information of the first network element to the second terminal device, and the second terminal device actively connects to the first network element based on the identifier information of the first network element. Method 2 is specifically described as follows.

[00122] Optionally, after receiving the first information, the second terminal device can transmit the third information to the first terminal device.

[00123] Optionally, the third piece of information can be used to indicate that the second terminal device has the capability to perform the first task of Petition 870250085835, dated 09 / 23 / 2025, page 33 / 150 27 / 51 detection. Optionally, the third information may include detection capability information from the second terminal device. Optionally, the detection capability information may include information such as a type of detection supported by the second terminal device and detection quality capabilities supported by the second terminal device.

[00124] Optionally, the first terminal device can determine, based on third-party information, that the second terminal device has the capability to serve as another UE that performs the first detection task.

[00125] Additionally, the first terminal device can transmit the fourth piece of information to the second terminal device.

[00126] Optionally, the fourth piece of information can be used to request that the second terminal device perform the first detection task. Optionally, the fourth piece of information can include one or more of the following: identification information for the first detection task, identification information for a detection request, a detection type, a detection quality requirement, identification information for a first network element, and identification information for the first terminal device.

[00127] Optionally, after receiving the fourth piece of information, the second terminal device can establish a connection with the first network element and interact with the first network element.

[00128] The specific implementation process for method 2 is described below in conjunction with Figure 8. In Petition 870250085835, dated 09 / 23 / 2025, page 34 / 150 28 / 51 Figure 8 shows that after receiving a UE-level detection request message and discovering UE1, the SF can transmit a discovery request message to UE1. UE1 can carry detection method information from a current detection task in the detection request message transmitted to UE2 around UE1 itself. After obtaining the UE information from UE2, UE1 can select another UE and transmit detection task request messages to the other selected UE. The other UE can establish a connection with the SF and directly report the detection data to the SF.

[00129] As illustrated in Figure 8, method 800 may include steps S810 to S880, which are specifically as follows.

[00130] In S810, a consumer invoice transmits a detection request message to the service provider.

[00131] A consumer NF can be a core network element, such as AMF, NEF, or an application server, such as AF or UE.

[00132] The detection request message may include information about a target UE (e.g., target UE ID information), the detection request message may additionally include a requested detection method and / or a requested detection service type, and the detection request message may include quality information required for a detection service, such as accuracy.

[00133] Target EU information may include one or more of the following:

[00134] a permanent signature identifier Petition 870250085835, dated 09 / 23 / 2025, p. 35 / 150 29 / 51 (SUPI) of the target EU, hidden signature identifier (SUCI) of the target EU, generic public signature identifier (GPSI) of the target EU, or other information of the target EU; and

[00135] Target EU address information (IP address, MAC address or similar).

[00136] Optionally, the SF or other network elements (e.g., the NEF) can map the target UE information to convert the target UE information into ID information (e.g., the SUPI) that can be used directly for queries within the core network.

[00137] In S820, SF queries UE1 based on target UE information (UE1 may be the first terminal device in the above modes).

[00138] Specifically, SF can discover UE1 by querying other network elements, such as AMF, a unified data repository (UDR), UDM, or by querying local information.

[00139] In S830, SF transmits a discovery request message to UE1.

[00140] The discovery request message may include the second piece of information in the above modalities.

[00141] The SF transmits the discovery request message to UE1 based on the detection request message, which may include information indicating the need to discover the assisting UE. Optionally, the detection request message may additionally include task / detection request identification information, the detection method (such as how UE A performs the transmission and UE B performs the reception, specifically, the detection request message may Petition 870250085835, dated 09 / 23 / 2025, p. 36 / 150 30 / 51 may additionally include an indication of the assisting UE as transmitter or receiver), the type of detection, the detection quality requirement or similar, and may additionally include SF ID information (e.g., SF device ID information, instance information in the 5GC, SF address information).

[00142] The detection type may include intrusion monitoring, target positioning, motion capture, speed / trajectory prediction, or similar, and the detection type may also be specific processing information from the request reporting channel (position information, Doppler frequency change information, point cloud information, or similar). The detection quality requirement may include information such as detection accuracy information, reporting frequency, and false alarm rate.

[00143] In S840, UE1 transmits a detection request message to UE2.

[00144] The detection request message may include initial information in the above modes.

[00145] For example, after receiving the discovery request message transmitted from SF, UE1 can transmit the detection request message to UE2 around UE1 via SL. The detection request message can include detection type, detection quality requirement, or similar.

[00146] Here, UE1 transmits the detection request message to UE2 around UE1 and can reuse an advertisement message or a request message transmitted by the PC5 interface in the current SL and Petition 870250085835, dated 09 / 23 / 2025, p. 37 / 150 31 / 51 Add information carried by the detection request message (e.g., initial information); UE1 can also first discover another SL UE using either the model for discovery model A or the model for discovery model B, and then initiate a request to another discovered SL UE using the detection request message; UE1 can also directly use a newly defined SL detection request message to transmit the detection request message, and the SL detection request message can be different from the existing request message, but can include the meaning of both discovering the SL UE and requesting that another UE perform the detection. After receiving the message, UE2 surrounding UE1 can simultaneously respond to UE1 with an SL UE discovery response and transmit a detection performance response as another UE to the SF.

[00147] In S850, UE2 transmits a reply message to UE1.

[00148] The reply message may include the third information in the above modalities.

[00149] After receiving the detection request message transmitted from UE1, UE2 can determine that UE2 can perform the detection task as another UE based on UE2's own detection capabilities and detection requirements, and transmit the response message to UE1. The response message may include an indication that UE2 can perform the detection task as another UE, and may additionally include UE2's detection capability information, such as a supported detection type, Petition 870250085835, dated 09 / 23 / 2025, p. 38 / 150 32 / 51 supported detection quality capabilities or similar.

[00150] On the S860, UE1 transmits a detection task request message to UE2.

[00151] The detection task request message may include the fourth piece of information in the modes above.

[00152] After receiving the response message from UE2, UE1 can select UE2 as another UE, and UE1 can transmit the detection task request message to UE2. The detection task request message can include detection task ID information, discovery request message ID information (which is consistent with that transmitted from the SF), the detection type, the detection quality requirement, or similar. The detection task request message can additionally include more SF ID information and, optionally, the detection task request message can additionally include more ID information from UE1 itself.

[00153] In S870, UE2 establishes a connection with the SF.

[00154] After receiving the detection task request message transmitted from UE1, UE2 can establish the connection with the SF using the SF ID information. Specifically, a session can be established using the SF user plane address information, or signaling interaction is performed via control plane signaling based on the SF ID information.

[00155] In S880, UE2 reports detection data Petition 870250085835, dated 09 / 23 / 2025, p. 39 / 150 33 / 51 for SF.

[00156] UE2 can report detection data to SF based on detection task ID information, discovery request message ID information (which is consistent with that transmitted from SF on S830 and the same transmitted from UE1 on S860), UE1 ID information, or similar.

[00157] In the present disclosure, UE1 transmits the detection request message to the UE surrounding UE1, to obtain the detection capability information from the UE, and selects another UE, and then transmits SF ID information to the other selected UE, so as to allow the other UE to communicate with the SF and report the detection data.

[00158] Method 3: The first terminal device reports to the first network element that the second terminal device has the capability to perform the first detection task. The first network element selects the second terminal device as another UE that performs the first detection task and establishes a connection with the second terminal device. Method 3 is specifically described as follows.

[00159] Optionally, after receiving the first information, the second terminal device can transmit the third information to the first terminal device.

[00160] Optionally, the third information may be used to indicate that the second terminal device has the capability to perform the first detection task. Optionally, the third information may include detection capability information of the second device. Petition 870250085835, dated 09 / 23 / 2025, page 40 / 150 34 / 51 terminal device.

[00161] Optionally, the first terminal device can transmit fifth information to the first network element based on the third information. Optionally, the fifth information can be used to indicate that the second terminal device has the capability to perform the first detection task.

[00162] Optionally, the fifth piece of information may include one or more of the following: identification information of the second terminal device, address information of the second terminal device, identification information of the first detection task, and identification information of the detection request.

[00163] Optionally, after selecting the second terminal device as another UE that performs the first detection task, the first network element can establish a connection with the second terminal device and interact with the second terminal device.

[00164] The specific implementation process of method 3 is described below in conjunction with Figure 9. In Figure 9, after receiving a UE-level detection request message and discovering UE1, the SF transmits a discovery request message to UE1. UE1 can carry detection manner information from a current detection task in the detection request message transmitted to UE2 around UE1 itself. UE1 obtains UE information from UE2 and notifies the SF, and SF can then make the subsequent selection of another UE.

[00165] As illustrated in Figure 9, method 900 may include steps S910 to S990, which are Petition 870250085835, dated 09 / 23 / 2025, page 41 / 150 35 / 51 specifically as follows.

[00166] In S910, a consumer invoice transmits a detection request message to the service provider.

[00167] A consumer NF can be a core network element, such as AMF, NEF, or an application server, such as AF or UE.

[00168] The detection request message may include information about a target UE (e.g., target UE ID information), the detection request message may additionally include a requested detection method and / or a requested detection service type, and the detection request message may include quality information required for a detection service, such as accuracy.

[00169] Target EU information may include one or more of the following:

[00170] a target UE Permanent Signature Identifier (SUPI), target UE Hidden Signature Identifier (SUCI), target UE Generic Public Signature Identifier (GPSI), or other target UE information; and

[00171] Target EU address information (IP address, MAC address or similar).

[00172] Optionally, the SF or other network elements (e.g., the NEF) can map the target UE information to convert the target UE information into ID information (e.g., the SUPI) that can be used directly for queries within the core network.

[00173] In S920, SF queries UE1 based on target UE information (UE1 may be the first terminal device in the above modes). Petition 870250085835, dated 09 / 23 / 2025, page 42 / 150 36 / 51

[00174] Specifically, SF can discover UE1 by querying other network elements, such as AMF, the UDR (Unified Data Repository), UDM, or by consulting local information.

[00175] In S930, SF transmits a discovery request message to UE1.

[00176] The discovery request message may include the second piece of information in the above modalities.

[00177] The SF transmits the discovery request message to UE1 based on the detection request message, which may include information indicating the assisting UE to discover. Optionally, the detection request message may additionally include task / detection request identification information, the detection method (such as how UE A performs the transmission and UE B performs the reception; specifically, the detection request message may additionally include an indication of the assisting UE as transmitter or receiver), the detection type, the detection quality requirement or similar, and may additionally include SF ID information (e.g., SF device ID information, instance information in 5GC, SF address information).

[00178] The detection type may include intrusion monitoring, target positioning, motion capture, speed / trajectory prediction or similar, and the detection type may also be specific processing information from the request reporting channel (position information, Doppler frequency change information, point cloud information or similar). A Petition 870250085835, dated 09 / 23 / 2025, page 43 / 150 37 / 51 detection quality requirements may include information such as detection accuracy, reporting frequency, and false alarm rate.

[00179] In S940, UE1 transmits a detection request message to UE2.

[00180] The detection request message may include initial information in the above modes.

[00181] For example, after receiving the discovery request message transmitted from the SF, UE1 can transmit the detection request message to UE2 around UE1 via SL. The detection request message can include detection task ID information, discovery request message ID information (which is consistent with that transmitted from the SF), the detection type, the detection quality requirement, or similar. The detection request message can additionally include the SF ID information and, optionally, the detection request message can also include more ID information from UE1 itself.

[00182] Here, UE1 transmits the discovery request message to UE2 surrounding UE1 and can reuse an advertisement message or a request message transmitted by the PC5 interface in the current SL and add information carried by the discovery request message (e.g., initial information); UE1 can also first discover another SL UE using the discovery model A or discovery model B template and then initiate a request to another discovered SL UE using the discovery request message; UE1 can also use Petition 870250085835, dated 09 / 23 / 2025, page 44 / 150 38 / 51 directly a newly defined SL detection request message to transmit the detection request message, and the SL detection request message may be different from the existing request message, but may include the meaning of both discovering the SL UE and requesting that another UE perform the detection. After receiving the message, UE2 around UE1 can simultaneously respond to UE1 with an SL UE discovery response and transmit a detection performance response as another UE to the SF.

[00183] In the S950, UE2 transmits a reply message to UE1.

[00184] The reply message may include the third information in the above modalities.

[00185] After receiving the detection request message transmitted from UE1, UE2 can determine that UE2 can perform the detection task as another UE based on UE2's own detection capabilities and UE2's own detection requirements and transmit the response message to UE1. The response message may include an indication that UE2 can perform the detection task as another UE, and may additionally include UE2 ID information and / or UE2 address information and UE2 detection capability information (e.g., a supported detection type, supported detection quality capabilities).

[00186] On the S960, UE1 transmits a discovery response message to SF.

[00187] The discovery response message may include the fifth piece of information in the above modes.

[00188] The discovery response message may Petition 870250085835, dated 09 / 23 / 2025, p. 45 / 150 39 / 51 contain the UE2 ID information and / or UE2 address information and, optionally, the discovery response message may additionally include the discovery task ID information, the discovery request message ID information (which is consistent with that transmitted from the SF) or similar.

[00189] In S970, SF selects another EU.

[00190] SF can obtain information from multiple selectable UEs (e.g., UE2 ID information and / or UE2 address information) based on the discovery response message reported by UE1 and select another UE.

[00191] In S980, SF establishes a connection with UE2.

[00192] SF can establish a user plane or control plane connection with multiple selected UE2s based on UE2 ID information and / or UE2 address information.

[00193] In S990, SF transmits a detection task request message to UE1 and UE2.

[00194] In the solution, the detection requirement and SF ID information are carried in the detection request message transmitted from UE1 to the UEs around UE1, to allow the UEs around UE1 to know if they can support the detection task. After selecting another UE, UE1 reports the information of the other selected UE to the SF, and the SF triggers the establishment of a connection with the other UE.

[00195] Together with Figures 1 to 9, the modalities of the method of the present disclosure are described in Petition 870250085835, dated 09 / 23 / 2025, p. 46 / 150 40 / 51 details above, and the embodiments of the apparatus of the present disclosure will be described in detail below in conjunction with Figures 10 to 13.
