[0033] Based on the above solution, the first access network device directly sends the sensing results to the first terminal, instead of sending the sensing results to the core network, then back from the core network to the access network, and finally transmitting them to the first terminal, thus saving transmission latency. This meets the needs of urgent scenarios where sensing results are used, such as in-vehicle navigation, intelligent driving, and / or flight equipment.

[0034] In some embodiments of the first aspect, the method further includes: receiving first information sent by a first core network device, the first information being used to perform a sensing task to obtain sensing results.

[0035] Based on the above scheme, the first information can be understood as the configuration information obtained from the configuration perception result. This is equivalent to the configuration information of the perception task coming from the first core network device. The execution of the perception task is controlled by the first core network device, which can ensure the orderliness and quality of the perception task execution.

[0036] In some embodiments of the first aspect, the first information includes at least one of the following:

[0043] The second instruction is used to instruct the first terminal to send the sensing results of the sensing task using either the first path or the second path; the first path does not pass through the core network; the second path passes through the core network.

[0044] The above scheme lists the relevant content of the first information. In practice, the relevant description of the first information is not limited to the first information. It can be flexibly selected in the specific implementation to meet the needs of different scenarios.

[0048] The above scheme lists the relevant content of the second configuration. In specific implementation, the content included in the second configuration can be flexibly selected to meet the needs of different scenarios.

[0050] Based on the above scheme, the sensing results can be sent to the first terminal using the first path or the second path according to the first information from the first core network, thereby meeting the transmission delay of the sensing results under different scenarios.

[0051] In some embodiments of the first aspect, directly sending the sensing result to the first terminal includes: sending Radio Resource Control (RRC) dedicated signaling to the first terminal, wherein the RRC dedicated signaling includes the sensing result.

[0052] Based on the above scheme, the sensing results are sent to the first terminal through RRC dedicated signaling, which has the characteristics of high flexibility.

[0054] Based on the above scheme, there are multiple ways for the first access network device to obtain sensing results. The specific implementation is not limited to any one of the methods mentioned above, thus satisfying the sensing result acquisition needs of first access network devices with different capabilities and / or in different state scenarios. For example, when the first access network device itself does not have the capability to process sensing data, it can receive sensing results from the first node. When the first access network device itself has the capability to process sensing data, it can generate sensing results itself, or, based on its own load rate and other relevant factors, receive sensing results from the first node when the load rate is higher than a threshold.

[0055] In some embodiments of the first aspect, the method further includes: sending a first message to a first node, the first message including a first request, the first request being used to request the first node to perform sensing data processing, the sensing result being the processing result of the sensing data; and receiving a second message sent by the first node, the second message being used to determine whether the second access network device accepts the execution of sensing data processing.

[0056] Based on the above scheme, the first access network device and the first node can successfully transmit relevant information about the execution of sensing tasks, such as the processing of sensing results, through the transmission of the first message and the second message.

[0057] In some embodiments of the first aspect, the first message includes one or more of the following: a first identifier for identifying a first terminal; second information including execution parameters of the sensing task; and a sensing result for the execution result of the sensing task.

[0058] Based on the above scheme, the first message includes a first identifier and / or second information, which enables the first node to know which terminal needs to provide the sensing results and / or how to perform the sensing task.

[0060] Based on the above scheme, the establishment of the first tunnel enables fast and secure information transmission between the first access network device and the first node, meeting the latency requirements of the sensing results.

[0061] In some embodiments of the first aspect, the second information further includes one or more of the following: a second identifier for identifying a sensing task; a first configuration for configuring sensing measurements to obtain sensing data of the sensing task; a second configuration for configuring the transmission of sensing data of the sensing task; a first indication for indicating that the sensing result of the sensing task is transmitted to the first terminal using a first path; the first path does not pass through the core network; a second indication for indicating that the sensing result of the sensing task is transmitted to the first terminal using either the first path or the second path; the first path does not pass through the core network; the second path passes through the core network.

[0062] Based on the above scheme, the second information also includes one or more of the following: a second identifier for identifying the sensing task; a first configuration for configuring sensing measurements to obtain sensing data of the sensing task; a second configuration for configuring the transmission of sensing data of the sensing task; a first instruction for instructing the use of a first path to transmit the sensing result of the sensing task to the first terminal; the first path does not pass through the core network; a second instruction for instructing the use of either the first path or the second path to transmit the sensing result of the sensing task to the first terminal; the first path does not pass through the core network; the second path passes through the core network.

[0063] Based on the above scheme, the second information includes part or all of the first information, which can facilitate the first node to know the relevant situation of the perception task execution.

[0064] In some embodiments of the first aspect, the first access network device includes a first base station and a second base station, and directly sending the sensing results to the first terminal includes: the first base station directly sending the sensing results to the first terminal; or, the second base station directly sending the sensing results obtained from the first base station to the first terminal.

[0065] Based on the above scheme, when the first terminal performs cell handover, the first base station sends a handover request to the second base station. The handover request includes a second indication, which is used to request the second base station to act as a processing node. The first base station receives a handover response from the second base station, which is used to determine whether the second base station agrees to act as a processing node to process the sensing data.

[0066] Based on the above scheme, the mobility of the first terminal is taken into consideration, and the processing of the sensing task is specifically provided. The second instruction is carried in the handover request, which saves signaling overhead by eliminating the need for a dedicated message. Moreover, when or before the first terminal switches to the second base station, the second base station knows that the first terminal has a need to receive the sensing results, so it needs to schedule relevant resources for the first terminal, which also improves the execution quality of the sensing task.

[0069] In some embodiments of the first aspect, the method further includes: if the second base station does not agree to perform the processing of the sensing data, performing the processing of the sensing data to obtain a sensing result; and sending the sensing result to the second base station.

[0070] Based on the above scheme, if the second base station does not agree to process the sensing data, the first base station will continue to acquire the sensing results and send the acquired sensing results to the second base station. In this way, even if the second base station does not support or finds it inconvenient to generate sensing results, the first base station can provide sensing results to the second base station, thereby ensuring service quality.

This cellular network sensing technology includes any one or more of the following: base station sensing and terminal sensing. Through the transmission and reception of wireless signals, and the processing of the transmitted and / or received signals, the following sensing-related results or information can be obtained:

[0242] Coordinate information, such as the coordinates relative to the receiving end of the wireless signal, can be calculated based on distance, horizontal angle, and vertical angle, for example.

[0243] Speed ​​information, such as the speed and direction of movement relative to the receiver of the wireless signal;

[0244] Behavioral pattern information, such as motion information like running, walking, approaching, falling, and swinging;

[0245] Weather information, such as rain, snow, etc.;

[0246] Traffic information, such as whether there is congestion, traffic accidents, or information on congested or accident-prone road sections.

[0247] The following is an introduction to Integrated Sensing and Communications (ISAC).

[0248] A wireless signal transmitter (hereinafter referred to as the transmitter) emits radio waves, and a wireless signal receiver (hereinafter referred to as the receiver) receives the radio waves. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase change, Doppler shift, and signal strength change. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes of the received signal, thereby obtaining information about the reflectors (e.g., coordinate information, velocity information, signal strength, and behavioral pattern information). In a wireless network (e.g., a cellular network), the wireless signal transmitter can be at least one of the following: a base station; a wireless access point, such as a Wi-Fi (WiFi) access point (AP); or a terminal.

[0249] The receiver of a wireless signal can be at least one of the following: a base station; a wireless access point; or a terminal.

[0250] The transmitter and receiver of the wireless signal can be from the same device or different devices. For example, depending on whether the transmitter and receiver are the same or different devices, the sensing model can include one or more of the following:

[0251] When the wireless signal transmitter and receiver are co-located, this sensing method can be called mono-static sensing. When the wireless signal transmitter and receiver are not co-located, this sensing method can be called bi-static sensing. In some embodiments, it is controlled by core network elements (e.g., SF-C). Data reporting is sent to the consumer, such as a vehicle (UE), via SF-D. A drawback of existing technologies is the latency of ISAC services, i.e., the application latency of ISAC sensing results. For example, in scenarios where the demand for sensing results is a car, and the service initiation is also by a car, timely application of sensing results is required, and the sensing service in a car scenario has high latency requirements.

[0252] As shown in Figure 2A, this embodiment of the present disclosure provides a sensing method, which is executed by the communication system shown in Figure 1A. The method may include:

[0253] S2101: The fourth message sent by the third terminal to the first core network device.

[0268] In other embodiments, if the first terminal has a subscription awareness result, the first core network device can directly send the first information to the serving base station of the first terminal without requiring a separate request from the fourth terminal. That is, the sending of the fourth message can be omitted. In other words, S2101 is an optional step.

[0279] It is worth noting that one or more of the third identifier, first configuration, second configuration, first indication, and second indication can be optional. For example, the first and second configurations can be determined by the first access network device itself, thus making them optional. If the transmission path for sending the sensing results is determined by the protocol or the local policy of the first access network device, then both the first and second indications can be optional. In some embodiments, the first access network device can select the processing node for the sensing task based on its own processing capabilities and the processing capabilities of one or more surrounding devices, without requiring specific instructions from the first core network device.

[0280] In some embodiments, the first configuration includes one or more of the following:

[0302] In some embodiments, the first cycle may be the cycle for processing sensing data to generate sensing tasks. The second cycle may be the cycle for periodically sending sensing data.

[0303] In some embodiments, event information is used to indicate a triggering event, which is a triggering event that occurs when a sensing node (e.g., the transmitter and / or receiver of the sensing signal) sends sensing data to a processing node. For example, if the intensity fluctuation of the measured sensing signal is detected to be greater than a specified value, a triggering event is considered to have been detected, and sensing data needs to be sent to the processing node.

[0304] Time information can also indicate one or more specific points in time or time intervals in the transmission of sensed data.

[0305] S2103: The first access network device acquires the sensing results.

[0323] In some embodiments, the first message includes a first request. Exemplarily, the first request is used to request a first node to perform sensing data processing. Exemplarily, the sensing result is the processing result of the sensing data.

[0324] For example, the processing of sensing data may include processing the sensing data using various processing methods to obtain sensing results.

[0325] In some embodiments, the first message may be a request message requesting the first node to participate in wireless sensing. In some embodiments, the first message may be a request message requesting the first node to perform sensing data processing to generate sensing results.

[0348] In some embodiments, the second message is a response to the first message. In some embodiments, sending the second message may be an optional step. For example, assuming the first node is not prepared to participate in the perception task, it may not need to send the second message, in which case the step of the first node sending the second message is optional.

[0349] In some embodiments, the second message may indicate whether the first node agrees to perform the processing of the sensed data.

[0350] In some embodiments, if the first node agrees to perform the processing of the sensing data, the first node will send the sensing results it generates to the first access network device, and the first access network device will receive the sensing results from the first node.

[0351] In some embodiments, if the first node refuses to act as the processing node for the sensed data, the second message may include a refusal indication.

[0352] In some embodiments, if the first node accepts a processing node as perceived data, the second message may include a consent instruction.

[0353] Thus, after receiving the second message, the first access network device can determine whether the first node agrees to continue processing the sensing data. If the currently selected first node refuses to serve as the sensing data processing node, the first access network device can promptly select another device as the first node.

[0354] S2104: The first access network device sends the sensing results to the first terminal.

[0355] In some embodiments, the first access network device directly sends the sensing results to the first terminal.

[0356] In some embodiments, the sensing results sent by the first access network device are transmitted to the first terminal without passing through the core network. For example, the sensing results sent by the first access network device are transmitted to the first terminal only through the access network.

[0357] In some embodiments, the first access network device directly sends the sensing results to the first terminal, which can be understood as: the sensing results sent by the first access network device directly reach the first terminal without passing through any intermediate device.

[0358] In some embodiments, after the first access network device obtains the sensing result, it directly sends the sensing result to the first terminal without going through the core network.

[0359] In some embodiments, the first access network device sends the sensing results to the first terminal using local breakout.

[0360] In some embodiments, the first access network device determines whether to directly send the sensing result to the first terminal based on first information. Exemplarily, if the first information includes a first indication, the sensing result is sent to the first terminal using a first path. Also exemplaryly, if the first information includes a second indication, the sensing result is sent to the first terminal using either the first path or the second path.

[0361] In some embodiments, the first access network device sends Radio Resource Control (RRC) dedicated signaling to the first terminal, the RRC dedicated signaling including the sensing result.

[0362] In some embodiments, the first access network device sends RRC dedicated signaling to the first terminal via an RRC connection.

In some embodiments, the step of establishing the second tunnel is optional; for example, the first base station and the second base station can also directly exchange data via an air interface such as Xn without using the second tunnel.

[0511] In some embodiments, the third core network device and the first core network device may be different core network devices of the same type. In some embodiments, the third core network device and the first core network device are the same device.

[0512] In some embodiments, if a direct channel is established between the second base station and the third core network device—for example, if the second base station can communicate directly with the third core network device based on the service interface—then the second base station can directly send a third message to the third core network device without requiring forwarding by the second core network device. From this perspective, steps S2305 and S2306 can be optional.

[0513] In some embodiments,

[0514] In some embodiments, the embodiments of FIG2A and FIG2D can be implemented individually or in combination. For example, if the first access network device in FIG2A is a first base station, the embodiment of FIG2A can be executed first, and then the embodiment corresponding to FIG2D can be executed when the first terminal performs cell handover.

[0515] Figures 1B and 1C illustrate two different embodiments of the sensing method. As shown in Figure 1B, the method includes:

[0516] Step 1: The in-vehicle device sends an ISAC service request to SF-C based on a third-party application.

[0517] Step 2: SF-C sends an ISAC service request to SF-D;

[0518] Step 3: SF-D local data verification.

[0519] Step 4: SF-D sends a sensing service response to SF-C;

[0520] Step 5: Establish an ISAC session between the base station and SF-C;

[0521] Step 6: Perception detection;

[0522] Step 7: The base station sends the processed sensing data to SF-D.

[0523] Step 8: Process the SF-D sensing data to obtain the sensing results.

[0524] Step 9: The processed compressed sensing results are sent to the third-party application of the vehicle device.

[0525] As shown in Figure 1C, the method includes:

[0526] Step 1: The in-vehicle device sends an ISAC service request to SF-C based on a third-party application.

[0527] Step 2: SF-C sends an ISAC service request to SF-D;

[0528] Step 3: SF-D local data verification.

[0529] Step 4: SF-D sends a sensing service response to SF-C;

[0530] Step 5: Establish an ISAC session between the base station and SF-C;

[0531] Step 6: Perception detection;

[0532] Step 7: Sensing data from the base station.

[0533] Step 8: The base station sends the processed compressed sensing results to SF-D;

[0534] Step 9: The processed compressed sensing results are sent to the third-party application of the vehicle device.

[0535] This processing method requires the sensing results to undergo data processing by the SF-D in the core network, resulting in long transmission paths and resulting latency issues. Therefore, this disclosure provides a wireless sensing method that allows sensing results to be quickly forwarded to consumers, such as vehicles (UEs), improving the latency requirements of sensing services, preventing accidents, and enhancing the user experience of sensing services. Figure 3A shows that the vehicle-mounted device establishes RRC connections with different base stations at different times. For example, at time T1, an RRC connection is established with gNB1. As the vehicle moves, at time T2, the vehicle moves to the boundary between the cell corresponding to gNB1 and the cell corresponding to gNB2. At this time, the vehicle-mounted device still has an RRC connection with gNB1, but at time T3, the vehicle-mounted device establishes an RRC connection with gNB2.

[0536] For vehicles lacking self-transmitting and self-receiving sensing capabilities, they can only request sensing from base stations, other UEs, or roadside units to obtain sensing data or results. To reduce latency in service establishment and application of sensing results, vehicles can directly request base stations to implement a self-transmitting and self-receiving mode, such as base station A transmitting and base station B receiving, or base station transmitting and UE receiving.

[0537] The solution presented here, taking a vehicle as an example, includes an ISAC task request initiated by any terminal (including the vehicle). During the vehicle's movement, the serving base station and the base stations participating in the sensing task may be the same or different, as shown in the diagram below.

[0538] Example 1:

[0539] A third party or vehicle (UE) establishes a sensing task through SF-C. SF-C selects nodes to participate in the sensing task, including base station nodes, terminal nodes, roadside unit nodes, etc. At this time, SF-C configures the nodes participating in the sensing. The specific configuration information provided by SF-C may include one or more of the following:

[0540] The node ID that performs sensing data processing facilitates the sending of sensing data from the sensing data acquisition node to the sensing data processing node.

[0541] Information is established through perception tasks.

[0542] Sensing and measurement configuration information.

[0543] Sensing data and reporting information, etc.

[0544] Simultaneously, SF-C will also establish a control signaling connection between the vehicle's serving base station and SF-C (for example, the serving base station can be called a sensing anchor base station). At this time, SF-C configures the serving base station.

[0545] Perform sensing data processing operations.

[0546] The sensing result is broken out locally and sent directly to the consumer via dedicated RRC signaling.

[0547] SF-C can also notify the base station of the sensing task ID or other sensing task identification information.

[0548] Alternatively, SF-C may notify the base station of the consumer's identification information, such as the UE's S-TMSI identifier or SUPI.

[0549] Information such as sensing task establishment, sensing measurement configuration, and / or sensing data reporting.

[0550] In addition, the UE can also provide sensing assistance information to the base station via RRC dedicated signaling, such as informing the base station of its consumer identity and sensing task identification information, and / or requesting sensing data to be sent directly to the UE. Based on the information reported by the UE and the information of the sensing task it has processed, the base station determines which UE should receive the sensing results directly.

[0551] As shown in Figure 3B, the sensing method includes:

[0552] Step 1: The in-vehicle device sends an ISAC service request to SF-C based on a third-party application.

[0561] Step 10: Sensing and detection of adjacent base stations.

[0562] Step 11: The serving base station receives the compressed sensing data from the neighboring base station.

[0563] Step 12: The serving base station sends the sensing results directly to the vehicle-mounted equipment via the RRC connection.

[0564] Example 2:

[0565] During the handover process, the handover request (HO Request) message carries indication information to instruct the target base station to allocate at least one GTP tunnel for the source base station to forward the following information to the target base station. The HO acknowledgment (ACK) message indicates the established GTP tunnel, which is identified by TEID. The GTP tunnel is used for: (a) forwarding sensing results that have not yet been sent to the UE to the target base station; (b) forwarding sensing data that has not yet been processed to the target base station; (c) forwarding intermediate sensing data that has not yet been processed to the target base station; (d) some preliminary input information required during the sensing processing at the target base station; and (e) the context information for sensing data processing at the target base station.

[0566] A GTP tunnel can be established for each sensing task and associated with a sensing task ID. The five types of information mentioned above can share a single GTP tunnel, or each type can use a dedicated GTP tunnel. Different sensing tasks can establish different GTP tunnels to achieve data isolation and ensure data security.

[0567] During the handover process, the handover request (HO Request) message carries indication information to instruct the target base station to allocate at least one GTP tunnel for the source base station to forward the following information to the target base station. The HO acknowledgment (ACK) message indicates the established GTP tunnel, which is identified by TEID. The GTP tunnel is used for: (a) forwarding sensing results that have not yet been sent to the UE to the target base station; (b) forwarding sensing data that has not yet been processed to the target base station; (c) forwarding intermediate sensing data that has not yet been processed to the target base station; (d) some preliminary input information required during the sensing processing at the target base station; and (e) the context information for sensing data processing at the target base station.

[0568] For each sensing task, a GTP tunnel is established and associated with a sensing task ID. The five types of information mentioned above can share a single GTP tunnel, or each type of information can use a dedicated GTP tunnel.

[0569] In the handover request, the handover request (HO Request) message carries the task ID of the current UE sensing task and the ID of the target SF-C, i.e., the routing ID.

[0570] In its path switching request to the AMF, the target base station also carries the task ID of the current UE sensing task and the ID of the target SF-C, i.e., the route ID, for path switching. Optionally, it also carries the ID of the sensing data processing node, which is the ID of the target base station to be switched.

[0571] The AMF initiates a sensing path switching process with the SF-C, causing the sensing link between the gNB and SF-C for that ue to migrate from the source base station to the target base station. Optionally, the AMF further notifies the SF-C of the ID of the sensing data processing node, which is the ID of the target base station being switched. The SF-C then notifies other participating sensing nodes about the new sensing data processing node, so that nodes acquiring sensing data know which node to send their sensing data to for processing and stop sending sensing data to the previous sensing data processing node.

[0572] As shown in Figure 3C, the sensing method includes:

[0573] Step 1: Base station 1 sends a handover (HO) request to base station 2. The HO request includes a sensing task ID and a routing ID, which can be used to identify the SF-C of the core network.

[0574] Step 2: Base station 2 sends an HO confirmation to base station 1.

[0575] Step 3: Sensing data processing of base station 2;

[0576] Step 4: Base station 2 initiates a path handover process and interacts with AMF for data exchange. For example, base station 2 and AMF exchange the sensing task ID and / or path ID.

[0577] Step 5: A sensing path handover is performed between AMF and SF-C. During the handover, AMF sends the sensing task ID to SF-C. In this way, SF-C will know which RAN node is currently serving the base station or processing the sensing data based on the information sent by AMF.

[0579] The source base station sends a HO request to the target base station, which includes a GTP tunnel establishment request indication and / or a data processing indication.

Exemplarily, this HO confirmation may include: at least one GTP tunnel identifier (TEID), the purpose of the GTP tunnel use (e.g., forwarding sensing results), or unprocessed sensing data and / or sensing context. Exemplarily, the sensing context may include execution parameters of the sensing task, acquired sensing data, sensing results, sensing area, and other information.

For example, this HO rejection may include: an indication to continue handling sensed data processing, at least one GTP tunnel identifier (TEID), and the purpose of using the GTP tunnel (e.g., for receiving sensed data). For the above three schemes, the base station maintaining a connection with the UE is called the anchor base station for the sensed task. It is responsible for billing processing, sensed data processing, and sensed result feedback, etc.

Additionally, for certain higher-level sensing information, since the sensing receiving terminal needs to process and obtain this information, the sensing management terminal may need to provide supplementary information for calculating the sensing results, such as the location information of the sensing transmitting terminal.

[0588] Sensing and measurement configuration includes configuration related to air interface resources, including configuration of measurement signals;
