[0246] In some cases, the rapid development of wireless communication technology and the growing demand for high-quality data transmission have driven the development of advanced communication systems. One promising technology is the integration of sensing and communication, which has the potential to revolutionize various industries, including automotive, healthcare, and smart cities.

[0247] In some embodiments, sensing is the use of radio frequency signals to obtain information about characteristics of the environment and / or objects in the environment (e.g., shape, size, direction, speed, position, distance or relative motion between objects, etc.).

[0248] In some embodiments, Integrated Sensing and Communication (ISAC) involves the simultaneous use of radio frequency (RF) signals for both sensing and communication. This integration can improve spectrum efficiency, reduce latency, and enhance reliability in a variety of applications. ISAC is particularly relevant in the context of mobile operators, user equipment (UE) vendors, automotive suppliers, and users, as it can significantly enhance the overall user experience, improve network efficiency, and enable new business opportunities.

[0249] In some embodiments, the integration of perception and communication enables the evolution of 3GPP networks from communication networks to integrated communication and sensing networks. It replicates the physical world through perception, exchanges information through communication, and connects the cyber and physical worlds, providing a key technical foundation for the fusion of the virtual and real worlds and expanding the scope of 3GPP technologies.

[0250] In some embodiments, the functional requirements and performance requirements of integrated perception and communication services with architectural impact are studied. In this study, perception applications, such as intruder detection applications (e.g., roads, railways, drone restricted areas, courtyards, and homes), monitoring applications (e.g., rainfall, tourism, floods, breathing, and movement), navigation assistance applications, real-time map generation applications, collision avoidance applications, etc. can be implemented using different perception methods through the 5G system to meet the required perception accuracy. For commercial, vehicle-to-everything (V2X), public safety, and emergency service use cases, target objects (and their environments) with or without UEs can be supported on licensed or unlicensed spectrum. The study also determined service requirements in terms of perception configuration, 5G wireless perception services, disclosure, security, charging, etc.

[0251] In some embodiments, mobile operators can play a significant role in providing customers with integrated 5GS-based perception and communication services, including, for example, the management and control of 5G-based perception services. A 5G-Automotive Association (5GAA) technical report (5GAA_White-Paper_C-V2X-Use-Cases-Volume-II.pdf) illustrates the role operators can play in enhancing V2X-type services, particularly in infrastructure-assisted environmental perception, infrastructure-based teleoperation, high-definition map collection and sharing, and teleoperation support.

[0252] In some embodiments, other example use cases where 5GS is studied to provide communication-assisted awareness services are as follows:

[0253] Real-time environmental monitoring: Utilize wireless signals to reconstruct environmental maps, further improve positioning accuracy, and enable environmental applications. This includes a range of real-time monitoring applications, including dynamic 3D map-assisted driving, pedestrian flow statistics, intrusion detection, and traffic detection.

[0254] Autonomous vehicles or drones: Autonomous vehicles and drones share some common functional requirements. For example, they should support Detect and Avoid (DAA) to avoid obstacles. They should also be able to monitor path information, such as selecting routes and complying with traffic regulations.

[0255] Air pollution monitoring: The quality of the received wireless signal exhibits different attenuation characteristics with changes in air humidity, air particulate matter concentration, carrier frequency, etc., and can be used for weather or air quality detection.

[0256] Indoor healthcare and intrusion detection. It can realize respiratory rate estimation, respiratory depth estimation, apnea detection, vital sign monitoring of the elderly and indoor intrusion detection.

[0257] In some embodiments, referring to FIG. 1b , the ISAC system includes the following different roles:

[0258] Object or environment: The target of perceived information.

[0259] Transmitter: A device that transmits radio signals to a target object. It can be a UE or a gNB.

[0260] Receiver: A device that detects sensing information based on the reflection of radio signals from target objects. It can be a UE or a gNB.

[0261] Processor: A device that collects perception information and processes it to produce perception results. It can be a UE, gNB, core network entity, or application server.

[0262] Consumer: An authorized device that requests or subscribes to perception information and consumes the output computed from the perception information, such as a UE application, ISAC service application server, core network entity, or RAN node.

[0263] In some embodiments, for a target object, the perception result may include shape, size, direction, speed, position, distance, or relative motion between objects.

[0264] In some embodiments, for a target environment, the perception result may include parameters describing the environment space or state.

[0265] In some embodiments, the perception result may be semi-processed data, which is not a final result.

[0266] In some embodiments, point cloud data can be used to represent the perception results of a target object or target environment or semi-processed data of the object or environment. However, point cloud data is usually massive, which seriously consumes network transmission resources.

[0267] In some embodiments, the sensing process also severely consumes air interface resources.

[0268] In some embodiments, it is necessary to consider how to generate perception results and disclose them to the terminal by intelligently consuming network resources.

[0494] In some embodiments, the above method may include the methods of the above-mentioned communication system side, first core network function, second core network function, access network equipment, etc., which will not be repeated here.

[0495] In order to better understand the embodiments of the present disclosure, some exemplary embodiments are further described below:

[0496] Example 1

[0497] In some embodiments, one use case for the ISAC service is to generate 3D map information from a vehicle. In this use case, the vehicle is an onboard UE equipped with lidar, radar, and a camera, and capable of acting as a transmitter or receiver. The vehicle performs fusion based on perception results obtained from the 3GPP network and information obtained from the lidar, radar, and camera. The fused data is then used to generate a 3D map at the vehicle.

[0498] In some embodiments, referring again to FIG. 7 a , an ISAC architecture is shown.

[0499] In some embodiments, a sensing function control plane function (SF-C) and a SF-UPF are introduced to process ISAC service requests, collect sensing data from receivers, and generate sensing results according to the ISAC service requests.

[0500] In some embodiments, the functions of SF-C include:

[0501] Receive ISAC service requests;

[0502] Selection of SF-UPF;

[0503] Query SF-UPF test results;

[0504] Management (creation, modification, termination) of the ISAC session between the SF-UPF and the gNB;

[0505] Control SF-UPF to deliver sensing results to consumers;

[0506] Transmitter or receiver selection;

[0507] Trigger the transmitter and / or receiver to perform a test.

[0508] In some embodiments, the functions of SF-UPF include:

[0509] Establish an ISAC session between the SF-UPF and the gNB under the control of the SF-C;

[0510] Under the control of the SMF, a PDU session is established between the SF-UPF and the UE, acting as a UPF.

[0511] processing the sensory data received from the receiver;

[0512] Storage and management of perception results;

[0513] Providing perception results based on the target perception area;

[0514] Trigger the transmitter and / or receiver to perform a test.

[0515] In some embodiments, at least one of the following interfaces is introduced:

[0516] NS0: Perception result query and perception data disclosure control between SF-C and SF-UPF;

[0517] NS1: Between UPF and SF-UPF, used to transmit sensing data on UP;

[0518] NS2: Between the gNB and SF-UPF, used to transmit sensing data on the UP.

[0519] In some embodiments, the SF-UPF is a NF that processes the sensory data received from the receiver. The processed sensory data is associated with a specific sensory area, location, time, or other characteristics. The processed sensory data is stored in the SF-UPF. If new sensory detection is performed for the same sensory area, location, or other characteristics, the processed sensory data can be updated.

[0520] In some embodiments, when an ISAC service request is received at the SF-C, it first checks with the SF-UPF whether there is available sensing data that matches the target sensing area and QoS requirements contained in the service request. If so, the SF-UPF provides the sensing results to the consumer on the user plane. Otherwise, the SF-C initiates a sensing process to detect sensing data within the target sensing area. The newly detected sensing data can be provided directly to the consumer or sent to the SF-UPF for further processing. Depending on the size of the sensing result information, the SF-UPF sends the sensing results with larger capacity to the consumer on the user plane or smaller capacity to the consumer on the control plane.

[0521] In some embodiments, to ensure that the SF-UPF's query for the sensing data of the target sensing area is successful, the SF-C selects the SF-UPF according to the SF-UPFs of the target sensing area and the serving sensing area received from the ISAC service request.

[0522] In some embodiments, to initiate the sensing process, the SF-C selects a transmitter and a receiver based on a target sensing area and a sensing entity serving the sensing area.

[0523] In some embodiments, to enable upward collection of sensing data from the gNB to the SF-UPF, the SF-C generates an ISAC service task based on the ISAC service request and binds the ISAC service task to the ISAC session between the gNB and the SF-UPF. If an existing session already exists, the SF-C binds the ISAC service task ID to the ISAC session ID; otherwise, a new ISAC session must be established.

[0524] In some embodiments, for ISAC session establishment, the SF-C sends an ISAC session establishment request, including the ISAC role ID and SF-UPF ID, to the selected gNB. The gNB creates a new session context, including the ISAC role ID and SF-UPF ID, and responds to the SF-C.

[0525] In some embodiments, upon receiving the response, the SF-C triggers the gNB to perform sensing by sending an ISAC service request. The gNB performs sensing based on the request, and the collected sensing data is sent to the SF-UPF via the uplink connection of the ISAC session.

[0526] In some embodiments, the collected sensory data may include:

[0527] Perceive channel measurement data;

[0528] Perceive point cloud data.

[0529] In some embodiments, the collected sensory data may be further processed at the SF-UPF and then provided to the consumer.

[0530] In some embodiments, the SF-UPF may perform the following sensing data processing:

[0531] Coordinate transformation;

[0532] Time conversion;

[0533] Speed ​​conversion.

[0534] In some embodiments, the sensing results exposed by the user to the UE:

[0535] If there is a PDU session between SF-UPF and UE, the perception result is provided to UE through UP.

[0536] Otherwise, the SF-UPF initiates the existing PDU session establishment procedure defined in TS 23.502 / 4.3.2 and executes as an application server.

[0537] Example 2:

[0538] Referring to FIG. 7 b , a communication method is shown, the method comprising:

[0539] Step S7101: The consumer UE sends an ISAC service request to the SF-C through the AMF. The request includes the target sensing area, consumer UE ID, validity period, required QoS, and expected sensing result (e.g., final result or semi-processed data).

[0540] Step S7102: SF-C selects SF-UPF according to the target perception area.

[0541] Step S7103: SF-C sends an ISAC service request to SF-UPF, including the target sensing area, user UE ID and required QoS.

[0542] Step S7104: SF-UPF queries local data based on the target sensing area, required QoS and validity time.

[0543] Step S7105: If matching sensing data is found, the SF-UPF responds to SF-C to send the sensing result to the consumer, skipping steps S7106-S71013; otherwise, the SF-UPF responds to SF-C that there is no available sensing result.

[0544] In step S7106, the SF-C selects a transmitter or receiver based on the target sensing area. The SF-C generates an ISAC service task ID for the ISAC service request. If an ISAC session exists between the gNB and the SF-UPF, the SF-C binds the ISAC service task ID to the ISAC session ID and skips steps S7107-S7109.

[0545] Step S7107: If there is no existing ISAC session between the gNB and the SF-UPF, the SF-C sends an ISAC session establishment request to the selected gNB, including the ISAC task ID and SF-UPF ID.

[0546] Step S7108: The gNB creates a new session context, including the ISAC task ID and SF-UPF ID.

[0547] Step S7109: The gNB responds to the SF-C of the established ISAC session.

[0548] Step S7110: Upon receiving the response, the SF-C triggers the gNB to perform sensing by sending an ISAC service request.

[0549] Step S7111: The gNB performs perception based on the request.

[0550] Step S7112: The gNB sends the collected sensing data to the SF-UPF via the uplink connection of the ISAC session.

[0551] Step S7113: Based on the received perception data and the expected perception result, the perception data may be further processed at the SF-UPF:

[0552] If the sensing channel measurement data is received, SF-UPF processes it into point cloud data;

[0553] If point cloud data is received, data conversion may be required depending on the expected results.

[0554] Step S7114: SF-UPF stores the processed sensor data locally.

[0555] Step S7115: If no PDU session exists between the SF-UPF and the UE, the SF-UPF initiates the PDU session establishment procedure defined in TS 23.502 / 4.3.2 and executes it as an application server; otherwise, this step is skipped.

[0556] Step S7116: Provide the sensing result to the UE through the user plane.

[0557] Example 3

[0558] See Figure 7c for the case where a vehicle uses ISAC services to generate 3D map information. The SF-UPF can be deployed in the same local data network as the gNB. If the sensing gNB is the UE's serving gNB, if the SF-UPF is configured with the sensing gNB, and if sensing data processing at the SF-UPF is skipped, the sensing data is sent directly from the gNB to the UE via a dedicated uplink channel, which is the optimized path.

[0559] A communication method is provided, comprising:

[0560] Step 7201: The vehicle sends an ISAC service request to the SF-C.

[0561] Step 7202: SF-C sends an ISAC service request to SF-UPF.

[0562] Step 7203: SF-UPF queries local data.

[0563] Step 7204: SF-UPF sends a service awareness response to SF-CFASONG.

[0564] Step 7205: An ISAC session is established between the access network device and the SF-C.

[0565] Step 7206: The access network device performs sensing.

[0566] Step 7207: The access network device sends the compressed perception point cloud data to the SF-UPF.

[0567] Step 7208: SF-UPF performs sensing data processing.

[0568] Step 7209: SF-UPF sends the compressed perception point cloud data to the vehicle.

[0569] The present disclosure reduces unnecessary abuse of wireless resources for performing perception detection by using a perception database in the SF-UPF to retrieve perception results from available perception data.

[0570] This disclosure introduces the SF-UPF, providing an optimized path for transmitting massive amounts of sensor data. When a gNB is selected as a transmitter or receiver, the SF-UPF can be deployed in the same local data network as the gNB. It also allows for charging and lawful interception at the SF-UPF.

[0571] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.
