[0113] Figure 2 is one of the interactive schematic diagrams of a perception capability deletion method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0114] Step 201: The first device sends a PDU session modification request to the fourth network element; wherein, the PDU session modification request is used to request the fourth network element to delete the sensing capabilities and / or sensing information of the Non-3GPP device;

[0115] The PDU session modification request includes: awareness capability deletion information or device information of the Non-3GPP device.

[0116] In current wireless communication systems, the rapid growth of wireless communication technology and the increasing demand for high-quality data transmission have led to the development of modern sensing systems. For example, there's Integrated Sensing and Communication (ISAC) technology, which integrates sensing and communication technologies. ISAC technology may impact multiple industries, including automotive, healthcare, and smart cities.

[0117] Specifically, sensing technology refers to acquiring information about the environment and / or objects in the environment through radio frequency signals, such as, but not limited to, shape, size, orientation, speed, position, distance, or relative motion between objects.

[0118] As an example, referring to Figure 7, the ISAC system includes the following roles: object or environment, transmitter, receiver, processor, and consumer.

[0119] Specifically, the perceived object or environment: the target object being perceived, which may not fall under the scope of the 3rd Generation Partnership Project (3GPP).

[0120] Sensing transmitter: A device that transmits radio signals (e.g., the radio frequency signals described above) to a sensing object. A sensing transmitter may include a UE or a gNB (gNodeB, a type of base station).

[0121] A sensing receiver is a device that detects sensing data (i.e., information obtained by sensing the target object, also known as the sensing information of the target object) based on radio signals reflected and / or diffracted by the target object (i.e., the sensing object). A sensing receiver may include a UE or a gNB.

[0122] Perception processor: A device that collects perception data, processes the collected perception data, and generates perception results. The processor may include UE, gNB, core network entity, or application server.

[0123] Sensing consumers / users: Authorized devices that request or subscribe to sensing data and calculate outputs based on the sensing data, such as UE applications, ISAC service application servers, core network entities, or RAN nodes (RAN stands for wireless access network).

[0124] For the target object, the perception results may include shape, size, orientation, speed, position, distance between objects, or relative motion (e.g., between the target object and the sensing signal receiver). For the target environment, the perception results may include parameters describing the environment's space or state.

[0125] In current 5G research, Non-3GPP devices can obtain services and interact with network devices (e.g., perform traffic exchange) by connecting to a UE or 5G-RG. The UE or 5G-RG matches with the Non-3GPP device through existing Packet Data Unit (PDU) sessions or by establishing new PDU sessions to meet the QoS (Quality of Service) requirements of the Non-3GPP device. In 6G, Non-3GPP devices may also possess awareness capabilities and support awareness services. Therefore, relevant mechanisms are needed to support awareness services for Non-3GPP devices.

[0126] In this embodiment of the disclosure, as an example, referring to Figure 8, in the sensing system architecture based on the 5th Generation Mobile Communication Technology (5G), the Radio Access Network (RAN) can access the User Plane Function (UPF) network element through the N3 interface; the UPF network element can access the Sensing Function-User Plane Function (SF-UPF) network element through the NS1 interface; the Network Slice Selection Function (NSSF) network element can access the bus interface through the Nnssf interface; the Network Exposure Function (NEF) network element can access the bus interface through the Nnef interface; the Network Repository Function (NRF) network element can access the bus interface through the Nnrf interface; the Policy Control Function (PCF) network element can access the bus interface through the Npcf interface; the Unified Data Management (UDM) network element can access the bus interface through the Nudf interface; and the Application Function (NO) network element can access the bus interface through the Nudf interface. Network elements with the following functions (AF, NSDSMF, NSSA, AF, NSSMF, NSSAAF, NSSAAF, NSSAAF, Authentication Server Function ...Network Slice Admission Control Function (NSACF) network elements connect to the bus interface via the NNSACF interface; Sensing Function Control Plane (SF-C) network elements connect to the bus interface via the NSF interface; UEs can connect to AMF network elements via the N1 interface; (R)ANs connect to AMF network elements via the N2 interface; UPF network elements connect to SMF network elements via the N4 interface; SMF network elements connect to SF-UPF network elements via the N9 interface; SF-UPF network elements connect to SF-C network elements via the NS0 interface; and (R)ANs connect to SF-C network elements via the NS2 interface.

[0127] Among them, user equipment and (wireless) access network entities can be service consumers, data processors, sensing receivers or sensing transmitters, and SF-UPF network elements can realize data processing or data storage functions.

[0128] In this embodiment, the network slice selection function network element, network capability opening function network element, network function repository function network element, policy control function network element, unified data management function network element, application function network element, service data management function network element, network slice selection authentication and authorization function network element, authentication server function network element, access and mobility management function, session management function, service control point, and network slice admission control function network element can be directly connected to the bus or connected to the bus through the corresponding network interface to jointly participate in the sensing process.

[0129] In this embodiment of the disclosure, the AF network element can also participate in the sensing process as a service consumer or a data processor, and the SDMF network element can participate in the sensing process as a data storage device.

[0130] In some embodiments, when a Non-3GPP device is connected to a UE / gateway, the Non-3GPP device can store its awareness capabilities in the network. However, if the Non-3GPP device disables its awareness service or disconnects from the UE / gateway, the network cannot delete the stored Non-3GPP device. Therefore, a mechanism for deleting awareness capabilities is needed.

[0131] Optionally, before the first device sends a PDU session modification request to the fourth network element, the first device matches the Non-3GPP device through an existing PDU session or by establishing a new PDU session (hereinafter referred to as the "existing PDU session or the newly established PDU session"), and sends a PDU session request to the fourth network element to request the fourth network element to modify the first PDU session, and to request the fourth network element to delete the sensing capabilities and / or sensing information of the Non-3GPP device.

[0132] Optionally, the fourth network element may delete the sensing capabilities and / or sensing information of the Non-3GPP devices already stored in the network based on the PDU session modification request sent by the first device.

[0133] In some embodiments, the Non-3GPP device may be a device that uses communication technologies and standards not defined by 3GPP.

For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
