[0060] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: several UEs 11 and several access devices 12.

[0061] UE11 can be a device that provides voice and / or data connectivity to a user. UE11 can communicate with one or more core networks via a Radio Access Network (RAN). UE11 can be an IoT UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 can be a device in an unmanned aerial vehicle (UAV). Alternatively, UE11 can be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0062] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0063] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0064] Access device 12 and UE11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0065] In some embodiments, UE11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0066] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0067] Several access devices 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0068] The wireless sensing method provided in this disclosure can be applied to, for example... Figure 2 The system architecture shown, but not limited to, is as follows. Figure 2 The system architecture shown.

[0069] Initiator: The sensing service is triggered based on application requirements and can be performed outside of the corresponding 3GPP communication system.

[0070] Consumer: Receives and consumes the output data of the sensing service; this data may include: sensing data and / or sensing results generated based on the sensing data;

[0071] Sensing Function (SF): This sensing function can be any functional entity on the network side. It is a type of network function. It determines the sensing model and the sensing parameters of the transmitter (or transmitter) and receiver (or receiver) based on the information / requirements provided by the initiator.

[0072] Transmitter: Transmits sensing signals based on the sensing parameters received from SF;

[0073] Receiver: Receives the reflected signal based on the sensing parameters received from SF; if there is sensing data, it sends the sensing data to the processor.

[0074] Processor: Processes the sensing data received from the receiver and outputs the sensing results. It is worth noting that the processor here may include one or more processors, or one or more processing devices.

[0075] It is worth noting that a device can act as one or more of the roles of initiator, consumer, transmitter, receiver, and processor.

[0076] like Figure 3 As shown, this disclosure provides a method for providing sensing services, wherein the method is executed by the AMF, and the method includes:

[0077] S110: Receive a sensing request, wherein the sensing request includes at least: UE identifier and base station identifier;

[0078] S120: Determine the target SF;

[0079] S130: Send the sensing request to the target SF.

[0080] The sensing request can come from the initiator or consumer of the sensing service, specifically from the UE or the application function (AF) of the sensing service.

[0081] The sensing request can come from a UE that requests sensing services or a UE that can provide sensing services to other UEs.

[0082] The UE identifier and base station identifier carried in the sensing request can both be: the candidate UE and candidate base station identifiers that provide sensing services.

[0083] The UE identifier includes, but is not limited to: the UE's International Mobile Equipment Identity (IMEI) and / or International Mobile Subscriber Identity (IMSI) or Temporary Mobile Subscriber Identity (TMSI).

[0084] The base station identifier may be the equipment identifier of the base station and / or the cell identifier of the cell formed by the base station. The cell identifier includes, but is not limited to, Physical Cell Identification (PCI).

[0085] If a sensing request is received, carrying the UE identifier and the base station identifier, the target SF can default to: the current sensing request prioritizes the use of the base station and UE to jointly provide sensing services, and therefore will prioritize the determination of sensing parameters suitable for the base station and UE to jointly provide sensing services.

[0086] In this embodiment of the disclosure, the AMF itself does not participate in providing sensing parameters. After receiving a sensing request, it will determine the target SF and send the sensing request to the target SF.

[0087] When the AMF receives a sensing request, it will determine the target SF that provides the sensing parameters, and then send the sensing request containing the UE identifier and the base station identifier to the target SF. In this way, the target SF will determine to bring the base station and UE into the sensing service providing system based on the UE identifier and the base station identifier carried in the sensing request, and provide sensing services.

[0088] Figure 4 The image shows wireless sensing based on radar waves.

[0089] The transmitter emits radar signals. When the radar signals encounter obstacles during transmission, they are reflected or absorbed. The reflected radar waves are received by the receiver. Based on the received radar waves, the receiver can perform radar ranging, radar detection, and other functions, thereby knowing the location, size, and / or shape of the obstacle.

[0090] The transmitter emits radar signals. When the radar signals encounter obstacles during transmission, they are reflected or absorbed. The reflected radar waves are received by the receiver. Based on the received radar waves, the receiver can perform radar ranging, radar detection, and other functions, thereby knowing the location, size, and / or shape of the obstacle.

[0091] like Figure 4 As shown, based on the transmission and reception time of radar waves, the distance between the sensing target and the transmitter and receiver equipment, as well as the direction relative to the transmitter and receiver equipment, can be determined.

[0092] Exemplary examples show that the specific uses of the sensing service described in this disclosure include, but are not limited to, at least one of the following:

[0093] Inspect the aircraft;

[0094] Obstacle detection;

[0095] Missile launch;

[0096] Spaceship navigation;

[0097] Maritime navigation;

[0098] Autonomous driving;

[0099] Weather forecast;

[0100] Terrain surveying, etc.

[0101] As a function for UE access and mobility management, AMF can select an appropriate SF to provide sensing parameters to the UE as needed.

[0102] This sensing request can be any request that provides sensing parameters and / or sensing services. The sensing request can be a Non-Access Stratum (NAS) message and / or an Access Stratum (AS) message.

[0103] The SF can be any functional entity on the network side, specifically, the SF can be one of the network elements of the core network and / or access network.

[0104] For example, the sensing function includes, but is not limited to, at least one of the following:

[0105] Access Function (AF);

[0106] Policy control function (PCF);

[0107] Or other network functions (NF).

[0108] Of course, the above are just examples, and the actual implementation is not limited to these. In some embodiments, the SF can be other network elements independent of AF, AMF, or PCF.

[0109] In one embodiment, the sensing request further includes:

[0110] Sensing model information, wherein the sensing model information indicates the sensing model used to provide sensing services;

[0111] The sensing model is as follows: the UE transmits a sensing signal, and the base station receives the reflected signal of the sensing signal transmitted by the UE; or, the base station transmits a sensing signal, and the UE receives the reflected signal of the sensing signal transmitted by the base station.

[0112] In this embodiment of the present disclosure, the sensing model indicated by the sensing request can indicate that one of the base station and the UE is the transmitter of the sensing signal, and the other is the receiver of the reflected signal formed by the sensing signal.

[0113] Figure 5 The diagram illustrates the base station as the transmitter of the sensing signal and the UE as the receiver. When a reflection object (RO) is acted upon by a sensing signal, it reflects the signal, altering the signal's propagation direction and generating a reflected signal that is received by the UE.

[0114] In practice, the UE can also be the one transmitting the sensing signal, while the UE can be the one receiving the reflected signal.

[0115] In some embodiments, the sensing model providing the sensing service may include at least one of the following:

[0116] The base station serves as the primary sensing model for both the transmitter and receiver.

[0117] User equipment (UE) serves as a second sensing model for both the transmitter and receiver;

[0118] A third-sensor model in which the base station acts as the transmitter and the UE acts as the receiver;

[0119] The fourth sensing model, in which the UE acts as the receiver and the base station acts as the transmitter;

[0120] A fifth sensing model other than the first to the fourth sensing models.

[0121] If the base station acts as both the transmitter and receiver, then the sensing service is essentially performed entirely by the network elements of the mobile communication network system.

[0122] The first sensing model may also involve a processor, which may be a base station, a computing device near the base station, or a UE, etc. The computing device includes, but is not limited to, an edge computing device or a remotely connected computing device.

[0123] In a second sensing model where the UE acts as both a transmitter and a receiver, the transmission and reception of sensing signals are performed by at least one or more UEs. In this case, the UE acting as the transmitter and the UE acting as the receiver in the second sensing model can be the same UE or different UEs. In embodiments of this disclosure, the UE sending the sensing request can be at least one of a transmitter and a receiver. Exemplarily, the UE can act as both a transmitter and a receiver simultaneously.

[0124] The second sensing model may also involve a processor, which may be a UE, a base station, or a computing device connected to a base station. This computing device includes, but is not limited to, edge computing devices or remotely connected computing devices.

[0125] The third sensing model involves a base station and a UE, with the base station acting as the transmitter and the UE as the receiver. In this case, the base station, as the transmitter, can transmit sensing signals to multiple UEs, thereby providing a one-to-many sensing service and offering sensing services to different UEs.

[0126] The third sensing model may also involve a processor, which can be a UE, a base station, or a computing device connected to a base station. This computing device includes, but is not limited to, edge computing devices or remotely connected computing devices.

[0127] The fourth sensing model involves a base station and a UE, with the base station acting as the receiver and the UE as the transmitter. In this case, the base station, as the transmitter, can receive sensing signals transmitted by multiple UEs at once due to its strong receiving capabilities, thereby enabling one-to-many sensing service provision and providing sensing services to different UEs.

[0128] The fourth sensing model may also involve a processor, which can be a UE, a base station, or a computing device connected to a base station. This computing device includes, but is not limited to, edge computing devices or remotely connected computing devices.

[0129] The fifth sensing model can be any sensing model other than the first to fourth sensing models mentioned above.

[0130] For example, the fifth sensing model may include a sensing model involving multiple transmitters and / or multiple receivers, and the types of transmitters may be different; for example, transmitters may include both UEs and base stations; and / or, receivers may include both UEs and base stations. Of course, devices acting as transmitters and receivers include, but are not limited to, base stations and / or UEs. In specific implementations, devices acting as transmitters and / or receivers may also be roadside devices capable of establishing connections with base stations or UEs. For example, roadside monitoring devices with wireless signal transmission and reception capabilities. Such monitoring devices include, but are not limited to, visual monitoring devices primarily focused on image acquisition.

[0131] The sensing request described in this embodiment carries a UE identifier and a base station identifier, indicating that the initiator of the sensing service expects to prioritize the use of the third sensing model and the fourth sensing model.

[0132] In some embodiments, the order of the UE identifier and base station identifier in the sensing request, or the fields used therein, can be used to determine whether the sender of the sensing request expects to use a third or fourth sensing model. For example, the sensing request can include a transmitter field and a receiver field, which can then be determined based on which field the UE identifier and base station identifier are carried in. As another example, the UE and network device can pre-negotiate that the identifier with the first identifier in the sensing request is the transmitter or receiver, and the other is either the receiver or transmitter. In this case, the order of the UE identifier and base station identifier in the sensing request can be used to determine the sensing model most desired by the sender of the sensing request.

[0133] In other embodiments, the sensing request directly carries sensing model information, which may be an identifier of the sensing model. In this way, the sensing model that the initiator of the sensing request intends to use can be determined directly based on the identifier of the sensing model.

[0134] In one embodiment, the sensing request may carry sensing model information of one or more sensing models. The sensing model information carried in the sensing request may be the sensing model that the sender of the sensing request expects to use. In this way, when one of the sensing models cannot be used, network-side network elements such as AMF or SF have other sensing models that the sender of the sensing request expects to use, thereby improving the service quality of the sensing service.

[0135] In some embodiments, if the sensing model indicated by the sensing request cannot be used to provide sensing services due to various information such as network conditions, network-side network elements such as AMF or SF can also determine other sensing models that can be used to sense the sensing target based on the current network conditions and the target information of the sensing target carried in the sensing request, thereby realizing the provision of sensing services.

[0136] The sensing request can be one or more of the above information, or it can be without the above information and only carry the sensing service request signaling.

[0137] In some embodiments, the request parameters may further include: consumer information, which indicates the consumer of the sensing service. The sensing results of the sensing service will be sent to the consumer for their use.

[0138] In one embodiment, the initiator and the consumer can be the same or different.

[0139] For example, the sensing request includes two required fields and one or more optional fields. The two required fields can carry initiator information and consumer information, respectively, while the other optional fields can carry various information such as the aforementioned sensing target information. Of course, this is just an example, and the actual implementation is not limited to this.

[0140] By carrying one or more of the above request parameters, SF can easily determine the sensing parameters suitable for the current scenario, thereby ensuring the service quality of the sensing service.

[0141] For example, the sensing target information includes at least one of the following:

[0142] The area of ​​the sensing target;

[0143] The area information of the sensing target;

[0144] The position of the sensing target;

[0145] The volume of the sensing target;

[0146] The speed of the sensing target.

[0147] In some embodiments, sensing targets of different areas and / or volumes can be used to determine parameters such as the viewing angle and / or power of the sensing signal transmitted by the transmitter.

[0148] The area information of the sensing target can indicate the current location of the sensing target, which can facilitate the determination of the sensing service area.

[0149] The location of the sensing target can be used to determine the executor, for example, to select a suitable executor nearby to perform the sensing service.

[0150] The speed of the sensing target can affect the successful provision of sensing services. For example, high-speed moving objects require a certain transmission power from the transmitter in the sensing service. Additionally, the motion of the sensing target can generate the Doppler effect, which places certain demands on the processing capabilities of the processor providing the sensing service.

[0151] In some embodiments, the target information is not limited to the area, position, volume, and / or velocity described above, but may also include the type of target. For example, whether the target is moving can be categorized as a static target or a dynamic target. Based on whether the target is a living object, it can be categorized as a living target or a non-living target. For living targets, the influence of radar spotlight on living objects, and negative impacts on living objects, may need to be considered.

[0152] In summary, the initiator can send the request parameters through the sensor request. The SF can determine the sensor parameters based on the request parameters and / or network information other than the request parameters. Based on the sensor parameters, the executor can provide sensor services with guaranteed security and quality of service.

[0153] In some embodiments, one or more of the request parameters in the sensing request can also be used by the AMF to determine the target SF. For example, the AMF selects the SF within the sensing area corresponding to the location of the UE and / or the location of the sensing target as the target service based on the UE location and / or the location of the sensing target indicated by the request parameters in the sensing request. As another example, the AMF selects the SF capable of providing the QoS indicated by the QoS information as the target SF based on the QoS of the sensing service indicated by the request parameters in the sensing request. These are merely examples.

[0154] In some embodiments, such as Figure 6 As shown, the method further includes:

[0155] S111: Determine whether the network supports providing the requested sensing service;

[0156] S120 may include: if the requested sensing function is supported, determining the target sensing function SF.

[0157] In some embodiments, if the network does not support providing sensing services, it determines that it cannot respond to the sensing request and refuses to respond to it. If the sensing request is refused, a request rejection message can be sent to the UE, which may carry a reason value indicating that the network does not support it. Upon receiving a request rejection message indicating that the network does not support the reason value, the UE will not resend the sensing request.

[0158] In other embodiments, the network supports providing sensing services, which can directly determine whether to respond to a sensing request, or further determine whether to respond to the sensing request based on other reference parameters such as the request parameters carried in the sensing request.

[0159] In one embodiment, determining whether the network supports providing the requested sensing service includes at least one of the following:

[0160] Determine whether the network supports the provision of the sensing service;

[0161] Determine whether the network side's verification of the sensing service is successful.

[0162] The verification provided by the sensing service includes, but is not limited to: authorization verification and / or privacy and security verification.

[0163] In some cases, the network may not be configured to provide sensing capabilities, meaning the network does not support sensing functionality. In other cases...

[0164] In some embodiments, when requesting sensing services, the sensing request will provide a suggested sensing model. If the current network side supports providing sensing services but does not support providing sensing services using the sensing model suggested by the UE, it can also refuse to respond to the sensing request. Alternatively, it can determine to respond to the sensing request if it supports providing sensing services using the sensing model suggested by the UE.

[0165] In some embodiments, determining whether to respond to the sensing request further includes:

[0166] Send a query request to the UDM, wherein the query request carries at least the UE identifier;

[0167] Receive a query response returned based on the query request, wherein the query response is used to determine whether the verification passed.

[0168] Whether the UE has subscribed to a sensing service, the UDM will retrieve the subscription data. The AMF can send a request to the UDM to query whether the UE has subscribed to the sensing service, or whether the UE has the QoS sensing service requested by the UE, or whether the UE has the sensing service provided by the sensing model recommended by the UE.

[0169] In one embodiment, the query response may include a query result that directly indicates whether the UE has subscribed to the sensing service.

[0170] In another embodiment, the query response may further include: UE subscription data, which indirectly indicates whether the UE has subscribed to the sensing service. If the AMF receives subscription data, the AMF needs to determine whether the UE has subscribed to the sensing service itself based on the subscription data.

[0171] In some embodiments, the request information further includes: QoS information and / or sensing model information contained in the sensing request;

[0172] The QoS information is used by the UDM to determine whether the UE has subscribed to a sensing service that meets the QoS information.

[0173] The sensing model information is used by the UDM to determine whether the UE has subscribed to the sensing service of the sensing model indicated by the sensing model information.

[0174] If the UE has subscribed to the sensing service indicated by the QoS information, it means that the UE has the authority to request the sensing service indicated by the QoS information.

[0175] For example, the QoS level will be different depending on the accuracy of the sensing service's location of the sensing target indicated by the QoS information.

[0176] As another example, the QoS information indicates that different guaranteed bandwidths for sensing services correspond to different QoS levels.

[0177] In one embodiment, S120 may include:

[0178] The target SF is selected from candidate SFs capable of providing the sensing service, based on at least one of the sensing request, the SF selection configuration of the AMF, and the network discovery mechanism.

[0179] In one embodiment, the AMF can directly determine the target SF based on the sensing request. For example, determining the target SF based on the sensing request may include:

[0180] The sensing area where the UE is located is determined based on the UE identifier included in the sensing request, and one or more candidate SFs are selected from the sensing area and determined as the target SF;

[0181] The target SF is determined based on the SF information indicated by the sensing request, wherein the SF information includes, but is not limited to, the identifier of the SF.

[0182] The SF selection configuration may include:

[0183] SF selection configuration for AMF local storage;

[0184] And / or,

[0185] SF selection configuration requested from PCF.

[0186] If the AMF locally stores the SF selection strategy, the AMF can determine the target SF based solely on the SF selection strategy, or determine the target SF based on the sensing request and the SF selection strategy.

[0187] If the AMF does not store the SF selection configuration locally, it requests the SF selection policy from the PCF and receives the policy information of the SF selection policy returned by the PCF to determine the target SF separately, or determines the target SF jointly based on the sensing request and the policy information of the SF selection policy returned by the PCF.

[0188] The AMF can also determine the target SF based on the network discovery mechanism, including but not limited to at least one of the following:

[0189] AMF will independently identify target SFs that can provide sensing services based on the network discovery mechanism.

[0190] AMF uses the sensor request and network discovery mechanism to discover the target SF that can provide the sensor service requested by the request parameters of the sensor request.

[0191] The detection mechanism can discover target SFs, including but not limited to at least one of the following:

[0192] The AMF sends a request message to the Network Repository Function (NRF); the request message may include: attribute information of the target SF that the AMF needs to discover;

[0193] The system receives a response message from the NRF, which may carry information about an SF that the NRF has queried based on the attribute information, indicating that the SF could serve as the target SF. This SF information includes, but is not limited to, the SF's identifier and / or its address information.

[0194] In one embodiment, the attribute information may be determined based on the sensing request. For example, the attribute information indicates the sensing area where the target SF is located, the type of sensing model supported, and the QoS of the sensing services that can be provided.

[0195] In another embodiment, the attribute information may separately indicate a service identifier for the sensing service, which can be used by the NRF to determine candidate SFs capable of providing the sensing service.

[0196] For example, the target SF may have one of the following characteristics:

[0197] The target SF and the UE are located in the same sensing area;

[0198] The target SF and the sensing target are located in the same sensing area;

[0199] The target SF is the SF that is closest to the UE and supports providing the sensing services requested by the UE;

[0200] The target SF is the SF closest to the AF of the sensing service or the target server;

[0201] The target SF is the SF located in the same sensing area as the AF of the sensing service or the target server.

[0202] The target SF is the SF suggested by the UE.

[0203] In summary, in this embodiment of the disclosure, the AMF determines the target SF responding to the sensing request based on at least one of the sensing request, the SF selection policy, and the network discovery mechanism.

[0204] like Figure 7 As shown, this functional embodiment provides a method for providing sensing services, wherein the method is executed by SF, and the method includes:

[0205] S210: Receive a sensing request; wherein the sensing request includes at least: UE identifier and base station identifier;

[0206] S220: Determine the sensing parameters according to the sensing request;

[0207] S230: Send the sensing parameters to the UE and the base station.

[0208] After receiving the UE's sensing request forwarded by the AMF, the SF determines the sensing parameters based on the request and sends the determined sensing parameters to the executor providing the sensing service. If the sensing service is provided using a third sensing model or a fourth sensing model, the receiver of the sensing parameters can be the UE represented by the UE identifier and the base station represented by the base station identifier. The sensing parameters may include at least one of the following:

[0209] Transmission parameters, for example, indicate: the type of sensor signal transmitted, the transmission frequency, the approximate direction of transmission, and / or the transmission period;

[0210] Receive parameters, for example, indicate: the reception period and / or the reception frequency;

[0211] Processing parameters, for example, the receiving parameters indicate a predetermined method for processing the sensor data.

[0212] If the target SF determines that the sensing model providing the sensing service adopts a third sensing model or a fourth sensing model, then the sensing parameters include:

[0213] The transmission parameters when the UE acts as the transmitter, and the reception parameters when the base station acts as the receiver;

[0214] or,

[0215] The receiving parameters when the UE acts as the receiver, and the transmitting parameters when the base station acts as the transmitter.

[0216] In some embodiments, the processing parameters may also be issued to the base station or UE, and the base station or UE itself processes the sensing data. It is worth noting that the UE and base station acting as executors here can be the UE and base station indicated by the UE identifier and base station identifier carried in the sensing request. The executor can also be a UE located near the UE indicated by the UE identifier carried in the sensing request, or a base station that can replace the base station indicated by the base station identifier carried in the sensing request to provide sensing services, for example, a base station near the base station indicated by the base station identifier.

[0217] In some embodiments, the method includes:

[0218] When the UE acts as the transmitter and the base station acts as the receiver, the transmission parameters are sent to the UE and the reception parameters are sent to the base station.

[0219] or,

[0220] When the UE acts as the receiver and the base station acts as the transmitter, the transmission parameters are sent to the base station and the reception parameters are sent to the UE.

[0221] The sensing parameters sent to the UE can be forwarded or transparently transmitted by the base station. For example, the sensing parameters sent to the UE can be carried in the information element (IE) or container of the signaling sent to the base station.

[0222] In some embodiments, the sensing parameters further include:

[0223] Processing parameters are used to process the sensor data formed by the receiver receiving the reflected signal.

[0224] The processing parameters are sent to the processor in the executor, which can be the transmitter, the receiver, or a third party other than the transmitter and receiver. For example, the processing parameters can be the initiator and / or consumer of the sensing request, or any network element within the mobile communication network.

[0225] In some embodiments, determining the sensing parameters based on the sensing request includes:

[0226] The sensing parameters are determined based on the sensing request and / or policy parameters.

[0227] Based on the candidate parameters provided in the sensing request, the sensing parameters are determined. For example, at least one of the candidate parameters is determined as the sensing parameter. Alternatively, based on the identifier of the candidate model and the device information of the candidate device carried in the sensing request, the executor providing the sensing service and the sensing model providing the sensing service are determined.

[0228] Determining the sensing parameters based on the strategy parameters may include:

[0229] Based on one or more sets of candidate parameters provided by the strategy parameters, a set of candidate parameters is randomly determined or selected in a predefined manner as the sensing parameters;

[0230] And / or,

[0231] Based on the range of sensing parameters defined by the strategy parameters, a set of parameters is selected from that range as the sensing parameters.

[0232] Determining the sensing parameters based on the sensing request and the policy parameters may include at least one of the following:

[0233] Determine whether the candidate parameters provided by the sensing request are included in the policy parameters. If they are included in the policy parameters, then the candidate parameters are determined as the sensing parameters; and / or, if they are not included in the policy parameters, randomly select a set of parameters from the policy parameters as the sensing parameters, or select the set of parameters from the policy parameters that is closest to the candidate parameters as the sensing parameters.

[0234] The above is merely an example of determining sensing parameters based on at least one of the sensing request and side policy parameters. In actual implementation, it is not limited to the above example.

[0235] In some embodiments, the strategy parameters include:

[0236] The local policy parameters of the SF;

[0237] The policy parameters provided by the policy control function PCF.

[0238] Policy parameters can be stored locally in the SF or requested from the PCF.

[0239] The local policy parameters of SF can be pre-configured in SF or transferred to SF after the last request from PCF.

[0240] If the policy parameters are not stored locally in the SF, the policy parameters can be requested from the PCF. Alternatively, if the policy parameters stored locally in the SF have a lower priority, the policy parameters with a higher priority can be requested from the PCF.

[0241] Of course, the above are just examples of the sources and / or acquisition methods of strategy parameters, and the actual implementation is not limited to this example.

[0242] In some embodiments, determining the sensing parameters based on at least one of the sensing request and the policy parameters includes:

[0243] Based on the sensing request, a policy request is sent to the policy control function (PCF);

[0244] Receive the policy response returned by the PCF; wherein the policy response includes policy parameters provided by the PCF;

[0245] The sensing parameters are determined based on the strategy response.

[0246] Requesting policy parameters from the PCF can be done by sending a policy request. This policy request can be UE-level or UE-group-level. If UE-level, the policy request carries the identifier of the corresponding UE; if UE-group-level, the policy request carries the group identifier of the UE group. If the policy request is UE-level, the policy parameters returned in the policy response apply only to the corresponding UE. If the policy request is UE-group-level, the policy parameters returned in the policy response apply to all UEs within the UE group. A UE group can include one or more UEs.

[0247] In one embodiment, the sensing request includes: the identifier of the UE;

[0248] The policy request includes the identifier of the UE; the policy response is returned based on the identifier of the UE.

[0249] If the policy request carries the UE identifier, the PCF can return a policy response for the UE based on the UE identifier.

[0250] In some embodiments, if the AMF fails to verify the provision of the sensing service, the SF may perform the verification. Alternatively, the SF may perform a second verification after the AMF has completed one verification.

[0251] Exemplarily, the method further includes:

[0252] Verify the initiator of the sensing request;

[0253] Determining the sensing parameters based on the sensing request includes:

[0254] After the verification is passed, the sensing parameters are determined according to the sensing request.

[0255] Verification ensures the security of the sensing service, including the security of the service delivery process and / or privacy. The initiator is verified, and the sensing parameters are only determined after verification. If verification fails, the sensing parameters are not provided.

[0256] Of course, if the verification of the initiator's identifier has been completed by the AMF, the SF does not need to perform verification again, but can directly determine the sensing parameters based on the sensing request.

[0257] The initiator can be the UE represented by the UE identifier carried in the aforementioned sensing request.

[0258] SF can perform local verification or request UDM for remote verification.

[0259] If remote verification is performed by UDM, then verifying the initiator of the sensing request includes:

[0260] Send a query request to the User Data Management (UDM);

[0261] The system receives a query response to the query request, wherein the query response is used to determine whether the verification is successful.

[0262] For example, based on the sensing request, a subscription query request is sent to the UDM. After receiving the subscription query request, the UDM will query the subscription data based on the UE's identifier to obtain the query response.

[0263] In one embodiment, the query response may include a validation result indicating whether the validation passed.

[0264] In another embodiment, the query response may include: queried subscription data. After receiving the subscription data, the SF processes the subscription information and generates a verification result indicating whether the verification is successful. If the returned subscription data indicates that the UE has not subscribed to the sensing service, the verification result indicates verification failure (i.e., verification fails); if the returned subscription data indicates that the UE has subscribed to the sensing service...

[0265] The verification includes:

[0266] Permission verification;

[0267] And / or,

[0268] Privacy and security verification.

[0269] The permission verification is: verifying whether the UE has the permission to obtain sensing services, and / or verifying what kind of sensing services the UE has permission to access.

[0270] The privacy and security verification is to check whether the UE's request to obtain sensing services would expose the privacy of other users or the user corresponding to the UE. If there is no privacy and security verification, the privacy and security verification is considered to be passed; otherwise, the privacy and security verification is considered to be failed.

[0271] The sensing parameters also include:

[0272] Address information of the AF; the address information of the AF is used by the base station and / or the UE to establish a transmission link with the AF;

[0273] And / or,

[0274] The address information of the initiator of the sensing service is used to establish a transmission link between the base station and / or the UE and the initiator.

[0275] The established transmission link is used to transmit sensing data and / or sensing results generated based on the sensing data.

[0276] If the sensing parameters include address information, this address information can be used by the executor to send sensing data and / or sensing results to the party that needs to receive the sensing data and / or sensing results.

[0277] For example, if the address information is the address information of the AF, the executor can establish a transmission link with the AF based on the address information. If the address information is the address information of the initiator of the sensing service, the address information can be used to establish a transmission link between the executor and the AF.

[0278] For example, if the executor does not send the sensing data and / or sensing results to the target SF, the target SF will carry the address information in the sensing parameters. In this way, the executor receives the address information and establishes a transmission link with the network element corresponding to the address indicated by the address information. The transmission link includes, but is not limited to, a TCP connection or a UDP connection.

[0279] In some embodiments, the sensing results include:

[0280] Intermediate results;

[0281] And / or,

[0282] Final result.

[0283] The sensor data undergoes preliminary processing to obtain intermediate results. These intermediate results do not include final results indicating the distance, orientation, and / or contour of the sensing target; rather, they are non-final results obtained from the preliminary processing. This preliminary processing may include: selecting valid data, removing outlier data, or calculating preliminary results for the final result. For example, invalid data may be removed, and sensor data selected for final result calculation may be used as the result of the preliminary processing and sent to the target SF, AF, initiator, and / or consumer.

[0284] The sensor data is processed to obtain the final result.

[0285] like Figure 8 As shown, this disclosure provides a method for providing sensing services, wherein the method is executed by a base station, and the method includes:

[0286] S310: Send a sensing request from the UE to the AMF;

[0287] S320: Receive the sensing response returned by SF in response to the sensing request;

[0288] S330: Obtain sensing parameters from the sensing response for the base station to provide sensing services;

[0289] S340: Send the sensing parameters in the sensing response used by the UE to provide sensing services to the UE.

[0290] The base station is the one selected to participate in providing sensing services, specifically an eNB and / or a gNB.

[0291] For example, the base station may be a base station whose base station identifier is carried in the sensing request, or a base station adjacent to the base station whose base station identifier is carried in the sensing request.

[0292] However, at least the base station is the serving base station of the UE that sent the sensing request.

[0293] After receiving a sensing request from the base station, it transmits or forwards it to the AMF.

[0294] The AMF will further send the sensing request to the SF. Therefore, after the SF determines the sensing parameters based on the sensing request, it will return the sensing parameters in the sensing response, and the base station will receive the sensing response.

[0295] After receiving the sensing response, the base station extracts sensing parameters for itself to use in providing sensing services. Simultaneously, the base station also sends sensing parameters extracted from the sensing response to the UE for providing sensing services. For example, the base station sends the necessary sensing parameters to the UE via RRC messages or MAC CE.

[0296] In some embodiments, receiving the sensing response returned by the SF in response to the sensing request includes:

[0297] The sensing response returned by the SF in response to the sensing request, sent through the AMF.

[0298] The sensor response is either forwarded or transmitted through the AMF.

[0299] In one embodiment, the method further includes at least one of the following:

[0300] Transmit a sensing signal based on the sensing parameters used by the base station to provide the sensing service;

[0301] Based on the sensing parameters used by the base station to provide the sensing service, sensing data is obtained by receiving the reflected signal formed by the reflection of the sensing signal transmitted by the UE.

[0302] The sensing data is processed to obtain the sensing result based on the sensing parameters used by the base station to provide the sensing service.

[0303] A base station can act as both a transmitter and a processor, or both a receiver and a processor, or it can act as a processor, transmitter, or receiver independently.

[0304] In one embodiment, the method further includes:

[0305] The sensor data is sent to the application function (AF) of the sensing service or the initiator.

[0306] or,

[0307] The sensing results are sent to the AF of the sensing service or the initiator.

[0308] The sensing results here can be the aforementioned intermediate results and / or final results.

[0309] Before sending sensor data and / or sensor results to the AF and / or the initiator, a transmission link can be established with the AF and / or the initiator based on the address information in the sensor parameters. This transmission link includes, but is not limited to, a TCP link and / or a UDP link.

[0310] like Figure 9AAs shown, this disclosure provides a method for providing sensing services, which is executed by a UE. The method includes:

[0311] S410: Send a sensing request to the AMF via the base station, wherein the sensing request includes at least: UE identifier and base station identifier, used by the AMF to determine the target SF for providing sensing parameters required for the sensing service.

[0312] The UE here can be the initiator of the sensing service and the sender of the sensing request. In this embodiment of the disclosure, the sensing request includes: a UE identifier and a base station identifier. The UE identifier can be the identifier of the UE that sent the sensing request, or it can be the identifier of other candidate UEs that the UE knows can be used to provide the sensing service.

[0313] The base station identifier can be the identifier of a candidate base station that the UE has identified or expects to provide sensing services. It can be the identifier of the UE's serving base station, or the identifier of a neighboring base station of the UE's serving base station, such as the identifier of a neighboring base station of the serving base station. Of course, the above is just an example of the UE and base station identified by the UE identifier and base station identifier carried in the sensing request.

[0314] In summary, the sensing request carries the UE identifier of the candidate UE that can provide or is expected to provide sensing services and the base station identifier of the candidate base station that can provide or is expected to provide sensing services.

[0315] In one embodiment, the sensing request includes at least one:

[0316] Sensing model information, indicating the sensing model of the sensing service;

[0317] QoS information, indicating the QoS required for the sensing service;

[0318] Base station identifier, indicating a base station capable of providing sensing services;

[0319] Target information of the sensing target.

[0320] For a detailed description of the sensing model, QoS information, base station identifier, and target information, please refer to any of the foregoing embodiments.

[0321] In one embodiment, the method further includes: receiving sensing parameters from the target SF transmitted by the base station.

[0322] In one embodiment, such as Figure 9B As shown, the method further includes:

[0323] S420: Receives sensing parameters from the target SF sent by the base station.

[0324] The sensing parameters provided by the target SF determined according to the sensing request are sent by the base station. Therefore, the UE will forward or pass through the sensing parameters from the target SF from the base station.

[0325] After receiving the sensing parameters from the UE, the base station can directly transmit or forward them.

[0326] For example, the sensing parameter may include at least one of the following:

[0327] Transmission parameters are used to transmit sensor signals;

[0328] Receive parameters are used to receive reflected signals based on sensor signals;

[0329] The signal processing unit is used to process the sensing data formed by the reflected signal received by the receiver to obtain the sensing result, which includes, but is not limited to, intermediate results and / or final results.

[0330] Therefore, in some embodiments, the method further includes at least one of the following:

[0331] Based on the transmission parameters in the sensing parameters, a sensing signal is transmitted;

[0332] Based on the receiving parameters in the sensing parameters, sensing signals are received to obtain sensing data;

[0333] The sensing data is processed according to the processing parameters in the sensing parameters to obtain the sensing result.

[0334] In some embodiments, the method further includes:

[0335] The sensor data is sent to the application function (AF) of the sensing service or the initiator.

[0336] or,

[0337] The sensing results are sent to the AF or the initiator of the sensing service.

[0338] For example, the sensing parameters also include address information, which can be used by the UE to establish a transmission link with the AF or the initiator, and this transmission link can be used to send sensing data and / or sensing results.

[0339] refer to Figure 10 As shown in the embodiments of this disclosure, a method for providing sensing services is provided, which may include:

[0340] 1. Receive a sensing request from the UE, determine whether the UE authorizes the establishment of a sensing service, and determine the transmission and reception related parameter configurations and related policy information required for the UE and gNB to implement the sensing service.

[0341] In this system, STx represents the transmitter of the sensing signal, and SRx represents the receiver of the reflected signal formed by the sensing signal acting on the reflection object (RO), i.e., the sensing target.

[0342] In this disclosure, various sensing models are provided depending on the transmitter and receiver of the sensing signal and the reflected signal.

[0343] For example, in the first sensing model: the UE is STx, and the gNB is SRx;

[0344] Second sensing model: STx and SRx are both UEs;

[0345] Second sensing model: STx and SRx are both base stations

[0346] Fourth sensing model: The base station acts as the transmitter, and the UE acts as the transmitter.

[0347] The fifth sensing model is any sensing model other than the first to the fourth sensing models.

[0348] If the base station acts as the transmitter, then the UE acts as the receiver; if the base station acts as the receiver, then the UE acts as the transmitter.

[0349] TRx / SRx means that the UE can act as both a sensor information transmitter and a sensor information receiver at the same time, and RO is the object being sensed.

[0350] Service Process:

[0351] Assume that the sensing capabilities of each Public Land Mobile Network (PLMN) change before a sensing request is made.

[0352] The UE initiates a sensing request to the AMF via the gNB. The sensing request includes: UE ID, sensing model information indicating the sensing model, and / or QoS information of the sensing service.

[0353] AMF checks whether the network supports the requested sensing service; if not, it rejects the request. When checking network support for the requested sensing service, methods such as... Figure 10 Step 2, authorization / privacy protection authentication, is shown below. The implementation process of Step 2 is as follows: For example, the AMF checks whether the UE has subscribed to the sensing service, whether it is permitted to use the sensing service, and whether it meets privacy and security protection requirements. If the UE has not subscribed to the sensing service, or the network prohibits providing the sensing service to the UE, or the provision of the sensing service would lead to privacy exposure, or other issues that do not meet privacy and security protection requirements, the request is rejected; otherwise, the request is accepted to provide the sensing service.

[0354] 3. SF selection, for example, AMF selects the SF based on the request and local configuration / policy.

[0355] 4. The AMF sends a sensing request to the selected SF, which includes the UE ID, gNB ID, sensing model system and / or QoS information.

[0356] Optional step 5: If necessary, the SF interacts with the AF / initiator or PCF to exchange policy parameters and / or contract data. Specifically, the SF obtains policy parameters when needed and obtains contract data from the UDM when needed.

[0357] 6. Determine the sensing parameters. For example, the SF determines the detailed configuration of the STx / SRx for the gNB and the UE. This detailed configuration may include at least the aforementioned sensing parameters for the UE and the base station to provide sensing services.

[0358] 7. The gNB receives the SF's sensor response through the AMF, including the gNB's sensor parameters and the UE's sensor parameters. The sensor parameters can be carried in the IE of the sensor response or in a container. This container carrying the sensor parameters can be called a sensor container.

[0359] 8. The UE receives a sensing response sent by the gNB, which may include at least the UE's sensing parameters;

[0360] 9. Sensing and detection, i.e., the UE and gNB provide sensing services, which may include: the UE and gNB are responsible for transmitting and receiving sensing signals and reflected signals.

[0361] Optional step 10: The UE / gNB sends sensing data and / or sensing results to the AF / initiator via the user plane / control plane as needed.

[0362] Before sending sensor data and / or sensor results, a transmission link can be established between the AF or the initiator based on the address information contained in the sensor parameters, and the sensor data and / or sensor results can be sent through the transmission link.

[0363] like Figure 11 As shown, this disclosure provides a sensing service providing apparatus, wherein the apparatus includes:

[0364] The first receiving module 110 is configured to receive a sensing request, wherein the sensing request includes at least: a user equipment (UE) identifier and a base station identifier;

[0368] In some embodiments, the first receiving module 110, the first determining module 120, and the first sending module 130 can all be program modules; after the program module is executed by the processor, it can realize the functions of the above-mentioned modules.

[0369] In other embodiments, the first receiving module 110, the first determining module 120, and the first sending module 130 may all be hardware-software hybrid modules; the hardware-software hybrid modules include, but are not limited to, various programmable arrays; the programmable arrays include, but are not limited to, field-programmable arrays and / or complex programmable arrays.

[0370] In some embodiments, the first receiving module 110, the first determining module 120, and the first sending module 130 may be purely hardware modules; the purely hardware modules include, but are not limited to, application-specific integrated circuits.

[0371] In some embodiments, the sensing request further includes:

[0372] The sensing model information indicates the sensing model used to provide sensing services.

[0373] The sensing model is as follows:

[0374] The UE transmits a sensing signal, and the base station receives the reflected signal of the sensing signal transmitted by the UE;

[0375] or,

[0376] The base station transmits a sensing signal, and the UE receives the reflected signal of the sensing signal transmitted by the base station.

[0377] Of course, in some embodiments, the sensing model is not limited to a sensing model in which one of the UE and the base station is the transmitter and the other is the receiver. Other sensing models include, but are not limited to, the aforementioned first sensing model, second sensing model and fifth sensing model, etc.

[0378] In some embodiments, the apparatus further includes:

[0379] The second determining module is configured to determine whether the network supports providing the requested sensing service;

[0380] The first determining module 120 is configured to determine the target sensing function SF if the requested sensing function is supported.

[0382] Determine whether the network supports the provision of the sensing service;

[0383] Determine whether the network side's verification of the sensing service is successful.
