Communication method and communication apparatus

[0001] The present application claims priority from the Chinese patent application No. 202411013485.8 filed on July 25, 2024, and entitled "Communication method and communication apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication, in particular to a communication method and a communication apparatus. BACKGROUND

[0003] The field of communication provides a wireless sensing service through a wireless sensing technology, i.e., the ability to obtain environmental and / or object feature information in the environment using radio frequency signals. Examples of object feature information include shape, size, direction, speed, position, distance between objects, or relative motion, etc. Further research is needed to charge for the use of the wireless sensing service. SUMMARY

[0004] The communication method and the communication apparatus provided by the present application implement a technical solution for charging the wireless sensing service, thereby providing support for the implementation of the wireless sensing service.

[0005] In a first aspect, the present application provides a communication method, which includes: determining, by a sensing control function entity, charging information, the charging information being used for charging a wireless sensing service; and sending, by the sensing control function entity, the charging information to a charging function entity.

[0006] In the method, the sensing control function entity obtains the charging information and sends the charging information to the charging function entity to assist in charging the wireless sensing service, thereby providing technical support for the implementation of the wireless sensing service. In addition, the sensing control function entity obtains the charging information and provides the charging information, which can make full use of information related to the wireless sensing service of the sensing control function entity, improve efficiency, reduce implementation complexity, and reduce charging costs.

[0007] The charging information in the method can be referred to as charging information of the wireless sensing service.

[0008] In combination with the first aspect, in a first possible implementation manner, the charging information includes an identifier of the wireless sensing service. The identifier of the wireless sensing service can be used to identify at least one of the following information: the service to be charged currently is a wireless sensing service, the service to be charged currently is which type of wireless sensing service, or the service to be charged currently is which specific wireless sensing service.

[0009] In a second possible implementation manner of the first aspect or the first possible implementation manner, the charging information comprises at least one of the following information related to the wireless sensing service: an application function identifier, a sensing event, a sensing mode, a sensing type, a sensing data traffic, a sensing result traffic, a sensing duration, a sensing area, a number of sensing objects, or a sensing service quality guarantee index. The above information can be used to more flexibly and accurately charge the wireless sensing service.

[0010] In some implementation manners, one or more of the sensing event, the sensing mode, the sensing type, the sensing data traffic, the sensing result traffic, the sensing duration, the sensing area, the number of sensing objects, and the sensing service quality guarantee index are combined to determine the charging manner.

[0011] For example, the sensing duration is included in the charging information, and a charging manner based on the sensing duration can be used; for another example, the sensing type is included in the charging information, and a charging manner based on the sensing type can be used.

[0012] In some implementation manners, one or more of the sensing event, the sensing mode, the sensing type, the sensing data traffic, the sensing result traffic, the sensing duration, the sensing area, the number of sensing objects, and the sensing service quality guarantee index are combined to determine the charging unit price.

[0013] For example, the application function identifier is used alone to determine the charging unit price, the charging unit price of the sensing service corresponding to the application function indicated by the application function identifier 1 is X1 yuan, and the charging unit price of the sensing service corresponding to the application function indicated by the application function identifier 2 is X2 yuan. The sensing event, the sensing mode, or the sensing type is used alone to determine the charging unit price, and the description is omitted here.

[0014] For example, the sensing data traffic is used to determine the charging unit price, the charging unit price is Y1 yuan when the sensing data traffic is in a first traffic range, and the charging unit price is Y2 yuan when the sensing data traffic is in a second traffic range. The sensing result traffic, the sensing duration, the sensing area, the number of sensing objects, or the sensing service quality guarantee index is used alone to determine the charging unit price, and the description is omitted here.

[0015] For example, the sensing mode and the sensing duration are combined to determine the charging unit price, the charging unit price is Z1 yuan when the sensing mode is base station sending and terminal receiving and the sensing duration is in a first duration range, the charging unit price is Z2 yuan when the sensing mode is base station sending and terminal receiving and the sensing duration is in a second duration range, and the charging unit price is Z3 yuan when the sensing mode is terminal sending and base station receiving and the sensing duration is in the first duration range. Other combinations are similar, and the description is omitted here.

[0016] In some embodiments, one or more of the traffic of the perception data, the traffic of the perception result, the perception duration, the perception area, and the number of the perception objects can be combined to determine the bill (or referred to as the fee).

[0017] For example, when the billing is based on the perception duration, the bill can be determined based on the billing unit and the perception duration. For example, the bill can be determined by multiplying the value obtained by rounding down the ratio of the perception duration to the billing unit and the billing unit price.

[0018] In combination with the second possible implementation, in a third possible implementation, the perception service quality guarantee indicator includes at least one of the following indicators: resolution distance, resolution angle, resolution speed measurement time, false alarm rate, or minimum radar cross section. By measuring the perception service quality through these indicators, the billing can be better supported, and the matching between the billing and the wireless perception service can be improved.

[0019] In some embodiments, one or more of the resolution distance, the resolution angle, the resolution speed measurement time, the false alarm rate, and the minimum radar cross section can be combined to determine the billing method.

[0020] For example, the minimum radar cross section is included in the billing information, and the billing method based on the minimum radar cross section can be used.

[0021] In some embodiments, one or more of the resolution distance, the resolution angle, the resolution speed measurement time, the false alarm rate, and the minimum radar cross section can be combined to determine the billing unit price.

[0022] For example, when the false alarm rate is used alone to determine the billing unit price, the billing unit price is S1 yuan when the false alarm rate is in the first range, and the billing unit price is S2 yuan when the false alarm rate is in the first range.

[0023] For example, when the resolution distance and the resolution angle are combined to determine the billing unit price, the billing unit price is T1 yuan when the resolution distance is in the first distance range and the resolution angle is in the first angle range, and the billing unit price is T2 yuan when the resolution distance is in the second distance range and the resolution angle is in the first angle range.

[0024] In combination with the second or third possible implementation, in a fourth possible implementation, the method further includes: the perception control function entity receiving the perception information from the perception processing function entity, the perception information including at least one of the following information: the traffic of the perception data, the traffic of the perception result, the number of the perception objects, or the perception service quality guarantee indicator. The perception control function entity obtains the billing information, including: the perception control function entity determines the billing information according to the perception information.

[0025] In this implementation, the perception control function entity acquires the charging information based on information received at the perception processing function entity, fully utilizes the function of the perception processing function entity to acquire the information, and facilitates the implementation of the charging function.

[0026] In combination with any one of the first to fourth possible implementation manners, in a fifth possible implementation manner, the method further includes: the perception control function entity receiving a perception service request message, the perception service request message including at least one of the following information: the perception duration, the application function identifier, the perception event, the perception mode, or the perception type. The perception control function entity acquiring the charging information includes: the perception control function entity determining the charging information according to the perception service request message.

[0027] In this implementation, the perception control function entity determines the charging information based on information received from other entities, which can improve the efficiency of acquiring the charging information.

The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) for accessing a terminal device to a wireless network. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B (NodeB), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), primary station, secondary station, multi-standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), radio unit (RU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

The embodiments of the present application do not limit the specific technology and specific device form of the network device.

[0105] A network device can be fixed, or mobile. For example, a helicopter or unmanned drone can be configured to act as a mobile base station, with one or more cells moving in accordance with the location of the mobile base station. In other examples, a helicopter or unmanned drone can be configured to act as a device that communicates with another base station.

[0106] In some deployments, a network device mentioned by embodiments of this application can be a device including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit-control plane (CU-CP)) and a user plane CU node (central unit-user plane (CU-UP)) and a DU node. For example, a network device can include a gNB-CU-CP, a gNB-CU-UP and a gNB-DU.

[0107] In some deployments, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, a RAN node can be a CU, a DU, a CU-CP, a CU-UP, or an RU, etc. The CU and the DU can be separately arranged, or can also be included in the same network element, for example, in a BBU. The RU can be included in a radio frequency device or a radio frequency unit, for example, included in an RRU, an AAU or an RRH.

[0108] The RAN node can support one or more types of fronthaul interfaces, different fronthaul interfaces respectively corresponding to DUs and RUs having different functions. If the fronthaul interface between the DU and the RU is a common public radio interface (CPRI), the DU is configured to implement one or more of baseband functions, and the RU is configured to implement one or more of radio frequency functions. If the fronthaul interface between the DU and the RU is another interface, which, relative to the CPRI, moves one or more of partial baseband functions of the downlink and / or uplink, such as, for the downlink, one or more of precoding, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / add cyclic prefix (CP), from the DU to the RU for implementation, and for the uplink, one or more of digital beamforming (BF), or fast Fourier transform (FFT) / remove cyclic prefix (CP), from the DU to the RU for implementation. In a possible implementation, the interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the splitting manner between the DU and the RU is different, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, and F.

[0109] Taking eCPRI Cat A as an example, for downlink transmission, with layer mapping as the cut, the DU is configured to implement layer mapping and one or more functions (i.e., one or more of encoding, rate matching, scrambling, modulation, layer mapping) before layer mapping, while other functions (e.g., one or more of resource element (RE) mapping, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / adding cyclic prefix (CP)) after layer mapping are implemented in the RU. For uplink transmission, with de-RE mapping as the cut, the DU is configured to implement de-mapping and one or more functions (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, de-RE mapping) before de-mapping, while other functions (e.g., one or more of digital BF or fast Fourier transform (FFT) / CP removal) after de-mapping are implemented in the RU. It can be understood that the function description of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, which is not described here.

In the embodiments of the present application, only the apparatus for implementing the function of the network device is taken as an example for description, and the scheme of the embodiments of the present application is not limited in this way.

[0113] The network device and / or the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; and can also be deployed on airplanes, balloons and satellites in the air.

[0118] Examples of related information of wireless sensing capability

[0119] In some implementations, the terminal device also has a sensing capability.

[0120] After the network device and / or the terminal device collects, senses or detects the sensing measurement data through the sensing capability, the network device and / or the terminal device transmits the sensing measurement data to a sensing processing function. In the embodiments of the present application, the sensing measurement data can be referred to as sensing data.

[0121] Sensing data: data derived from 3GPP radio signals that are affected (e.g., reflected, refracted, diffracted) by objects or environments of interest for sensing purposes and optionally processed within the communication system.

[0122] Network exposure function (NEF): used to connect the interaction between other internal network elements of the core network and the application server outside the core network, to provide network capability information to the external application server, or to provide the information of the external application server to the network element of the core network.

[0124] Sensing processing function: processes the sensing data obtained from the network device or the UE, generates corresponding sensing results, and provides the sensing results to the sensing control function and the external requester. The external requester can be the AF, the NEF or the UE. The sensing processing function can be referred to as the SPF (sensing processing function).

[0125] Sensing control function: based on the sensing service request of the AF, the NEF or the UE, selects corresponding network devices or UEs to detect the sensing data, and selects corresponding SPFs to process the sensing data.

[0126] In subsequent embodiments of the present application, the sensing control function entity is referred to as SCF, the sensing processing function entity is referred to as SPF, the AF entity is referred to as AF, and the NEF entity is referred to as NEF.

[0127] In the embodiments of the present application, sensing can be replaced by detection.

[0128] FIG. 2 is an exemplary flow chart of a communication method according to an embodiment of the present application. As shown in FIG. 2, the method comprises S210, S220, S230, S240, S250, S260 and S270.

[0129] At S210, the perceiver sends a perception request message to the SCF. Accordingly, the SCF receives the perception request message from the perceiver. This step can be referred to as obtaining the perception service requirement.

[0130] The perceiver can be a UE and / or an AF. The AF can send the perception request message to the SCF through the NEF, and the UE can send the perception request message to the SCF through the network device.

[0131] The perception request message is used to request a wireless perception service. The perception request message can also be referred to as a perception service request message.

[0132] Optionally, the perception request message carries a perceiver identifier of the wireless perception service.

[0133] The perceiver identifier is used to indicate the perceiver who requests the wireless perception service.

[0134] As an example, the identifier of the wireless perception service can be an identifier of a wireless perception application (APP).

[0135] As an example, the perception request message carries a perception requirement, which can include at least one of the following information: a perception target, a perception mode, a perception type, a perception quality of service indicator, a perception area, a perception time, or a perception event.

[0136] As an example, the perception target includes a location area object, a number, a speed, a location, etc. For example, the number of detected drones in a drone perception scenario. In embodiments of the present application, the perception target can also be referred to as a perception object.

[0137] As an example, the perception mode includes: a network device as a sender and a receiver of a perception signal, a UE as a sender and a receiver of a perception signal, a network device as a sender of a perception signal and a UE as a receiver of a perception signal, and a UE as a sender of a perception signal and a network device as a receiver of a perception signal.

[0138] As an example, the perception type includes one or more of the following: object distribution, map, driving, violation detection, object trajectory monitoring, emergency event detection, object positioning, object contour size, object speed, weather prediction, human posture, or human health.

[0139] In one example, the violation detection is vehicle violation detection, and the violation detection includes one or more of the following: overspeeding detection, violation lane occupation detection, emergency lane occupation detection, violation lane changing detection, vehicle type and license plate mismatch detection, or abnormal driving route detection.

[0140] In another example, the violation detection is aircraft violation detection, and the violation detection includes one or more of the following: overspeeding detection, flight route violation detection, violation airway changing detection, aircraft type and identity mismatch detection, or aircraft violation cargo detection.

[0141] In one example, the driving includes one or more of the following types: vehicle automatic driving, vehicle semi-automatic driving, vehicle remote driving, vehicle following, vehicle driving assistance, aircraft automatic driving, aircraft semi-automatic driving, aircraft remote driving, or aircraft driving assistance.

[0142] In one example, the emergency detection includes one or more of the following detection types: an object entering a specific area range, an object collision, an object collision risk, a disaster occurrence, or a disaster risk occurrence.

[0143] An example of an object entering a specific area range includes: a foreign object invading a railway track, or a drone invading a no-fly zone (e.g., an airport).

[0144] An example of an object collision includes: a vehicle or a drone colliding during driving. At this time, the perception detection needs to be notified to other vehicles or drones.

[0145] An example of an object collision risk includes: a vehicle or a drone driving, a person or an object suddenly appearing a dangerous event, which may cause a collision. At this time, the perception detection needs to be notified to the relevant vehicle or drone to avoid collision.

[0146] An example of a disaster occurrence includes: a flood due to heavy rain. At this time, the perception detection needs to be notified to relevant personnel for risk avoidance.

[0147] An example of a disaster risk occurrence includes: a flood may occur due to heavy rain. At this time, the perception detection needs to be notified to relevant personnel for warning and disaster prevention.

[0148] In one example, the weather forecast includes one or more of the following types: temperature, air pressure, humidity, rainfall, snowfall, wind speed, wind direction, cloud thickness, suspended particulate matter concentration, or air quality.

[0149] In one example, the human health includes one or more of the following types: breathing, heartbeat, blood pressure, body weight, skin health, sleep quality, or organ abnormalities.

[0150] The perception event can refer to a sub-type under each perception type. For example, the perception event can include vehicle inspection in the violation detection type, vehicle speed detection, vehicle automatic driving in the driving type, vehicle platooning, dynamic map in the map type, etc.

[0151] As an example, the perception service quality indicator includes one or more of: a perception distance, a perception speed range, a perception distance resolution, a perception angle accuracy, a perception speed resolution, a perception QoS indicator, a perception location point, a perception UE identifier, a perception object identification accuracy, a perception object identification false alarm rate, a perception data accuracy, a perception data update frequency, a minimum radar cross section, a perception dimension indication, or a perception feedback mode.

[0152] In an embodiment of the present application, the perception distance resolution, the perception angle accuracy, the perception speed resolution, the perception object identification accuracy, and the perception data accuracy can be collectively referred to as perception accuracy.

[0153] The perception distance resolution refers to the minimum distance at which two targets located at the same azimuth angle but with different distances from the perception network element are distinguished. That is, the perception distance resolution defines the ability of the perception network element to distinguish two close-range targets.

[0154] The perception angle accuracy refers to the ability of the perception network element to distinguish adjacent targets in terms of angle, which is usually measured in terms of the smallest distinguishable angle. Alternatively, the angle accuracy can also be referred to as the angle resolution.

[0155] The perception speed resolution refers to the ability of the perception network element to distinguish targets in terms of radial speed. Alternatively, the perception speed resolution can be a perception speed accuracy range or a perception speed error range.

[0156] The perception location point can be an absolute coordinate or a relative coordinate of a geographical location, without limitation.

[0157] The UE identifier can be an external identifier of the UE, such as a generic public subscription identifier (GPSI).

[0158] By way of example, the perception object identification accuracy refers to the probability that an actual target is judged to be a target.

[0159] For example, if the probability that an actual target is judged to be a target is P, then the probability that an actual target is judged to be no target is 1-P.

[0160] As an example, the perception object recognition accuracy is an accuracy of recognition of the target object obtained by using at least one of the perception distance resolution, the perception angle resolution, and the perception speed resolution.

[0161] As an example, the perception object recognition false alarm rate refers to a probability that a target actually does not exist but is determined to exist, or a probability that a target actually exists but is determined not to exist.

[0162] For example, if the probability that a target actually does not exist but is determined to exist is Q, then the probability that a target actually exists but is determined not to exist is 1-Q.

[0163] It should be noted that the object recognition accuracy and the object recognition false alarm rate are two different parameters.

[0164] Optionally, the perception object recognition false alarm rate can be a false alarm rate of recognition of the target object obtained by using at least one of the perception distance resolution, the perception angle resolution, and the perception speed resolution.

[0165] In addition, the object recognition accuracy or the object recognition false alarm rate can also be replaced by recognition of a scattering point of the target object. That is, a success rate of recognition and a false alarm rate of recognition of the target object are obtained according to at least one of the perception distance resolution, the perception angle resolution, and the perception speed resolution.

[0166] As an example, the perception data accuracy can be an image resolution.

[0167] As an example, the perception data update frequency can be an image frame rate.

[0168] In addition, it should be noted that the perception data update frequency is distinguished from a feedback period of the perception data.

[0169] For example, taking a video image as an example, the data update frequency is a video frame rate, and the higher the frame rate, the better the continuity, for example, 60 frames per second (fps) means that there are 60 pictures in 1 second of video. The feedback period refers to feeding back a continuous video frame every certain time (for example, 10 seconds).

[0170] Optionally, the perception dimension indication is used to indicate a dimension of the perception data.

[0171] For example, the perception dimension indication indicates that the perception data is two-dimensional plane data or three-dimensional data.

[0172] As an example, the perception feedback mode can be one or more of the following: single feedback, periodic feedback, or event-triggered feedback.

[0173] In the case where the perception feedback mode is periodic feedback, the perception service quality index of the wireless perception service can further include a feedback period of the perception data.

[0174] For example, the perception QoS indicator can include one or more of: a perception service priority, a data rate, a latency, an object recognition accuracy.

[0175] Alternatively, the object recognition accuracy in the perception QoS indicator can be an object recognition error rate. In other words, the perception QoS indicator can include one of the object recognition accuracy and the object recognition error rate.

[0176] Optionally, the perception QoS indicator further includes one or more of: a QoS parameter identifier, a priority corresponding to the QoS parameter identifier.

[0177] For example, the perception QoS indicator includes the QoS parameter indicated by the QoS parameter identifier. Optionally, the QoS parameter is one or more.

[0178] For example, the perception area refers to the service range of which network devices, or can be which physical area.

[0179] For example, the perception time includes a time length, or includes a start time and an end time, etc.

[0180] S220, the SCF selects a perception device based on the perception request message, the perception device including a network device and / or a UE.

[0181] In some implementations, the SCF further selects an SPF for processing the perception data obtained by the perception device.

[0182] S230, the SCF sends a perception indication message to the perception device, instructing the perception device to perform perception. Correspondingly, the perception device receives the perception indication message.

[0183] In some implementations, the SCF instructs the perception device to transmit the perception data to which SPF after the perception device completes the perception.

[0184] For example, the perception indication message carries a perception requirement, which can include at least one of the following information: a perception target, a perception area, a perception time length, a perception mode, a perception type, a perception quality of service indicator, or a perception event.

[0185] In some implementations, the at least one information carried in the perception indication message can be all or part of the information carried in the perception request message, or be determined by the SCF based on the perception request message.

[0186] For example, the sensing distance indicated in the sensing request message is 200 meters, but based on some other requirements, such as the need for redundant sensing data to improve sensing accuracy, the SCF can indicate in the sensing indication message that the sensing distance is 200 meters.

[0187] For example, the sensing area in the sensing request message is a 10 kilometer (km) x 10 km area range, and the sensing range of a single sensing device is a 3 km x 3 km area range. The SCF needs to determine the sensing device and the range of the sensing area indicated to each sensing device according to the 10 kilometer (km) x 10 km area range and the 3 km x 3 km area range.

[0188] For example, the sensing area in the sensing request message corresponds to 3 base stations, but in fact there are currently only 2 base stations available for sensing, so the actual sensing area corresponds to two 2 base stations.

[0189] As an example, there are 10 sensing location points in the sensing request message, and the SCF determines that they need to be sensed by 3 different sensing devices respectively, sensing device A senses 4 of them, sensing device B senses 3 of them, and sensing device C senses 3 of them. In this way, the sensing location points in the sensing indication information sent by the SCF to different sensing devices are different from the sensing location points in the sensing request message.

[0190] Alternatively, the sensing location points in the sensing indication message and the sensing location points in the sensing request message can be the same.

[0191] As an example, the sensing UE identifier in the sensing request message is an external identifier (such as GPSI), which is converted by the SCF into an internal identifier, such as a user permanent identifier (SUPI) or a globally unique temporary identity (GUTI) or a system architecture evolution-temporary mobile subscriber identity (S-TMSI) or a next generation application protocol identifier (NGAP ID) or a cell-radio temporary identity (C-RNTI), or other internal UE IDs that can be identified by the first sensing network element.

[0192] As an example, the sensing time in the sensing request message is 100 seconds (s), and the SCF sets the sensing duration in the sensing indication message to be greater than 100 s, for example, 110 s, for processing redundancy of subsequent sensing data processing.

[0193] Optionally, the sensing duration in the sensing request message and the sensing duration in the sensing indication message can be the same.

[0194] As an example, for the feedback mode, in the case of multiple sensing request messages requesting the same sensing service, some sensing request messages request single sensing, and some sensing request messages request periodic sensing, the SCF can aggregate. For example, the sensing feedback mode in the sensing indication message is set to periodic sensing.

[0195] Optionally, the sensing feedback mode in the sensing request message and the sensing feedback mode in the sensing indication message can be the same.

[0196] Similarly, for the sensing feedback period, in the case of multiple sensing request messages requesting the same sensing service, the feedback periods requested by different sensing requesters are different, the SCF can aggregate. For example, the sensing feedback period 1 in one sensing request message is 5 s, and the sensing feedback period 2 in one sensing request message is 10 s, and the SCF can set the sensing feedback period in the sensing indication message to 5 s.

[0197] As an example, the QoS indicator time delay in the sensing request message is 100 milliseconds (ms), and the SCF needs to consider the end-to-end time delay, including the data transmission time delay of each interface, the sensing data processing time delay, the time delay redundancy, etc., and can set the QoS indicator time delay in the sensing indication message to be less than 100 ms, such as 80 ms.

[0198] For another example, the QoS indicator sensing time delay 100 ms in the sensing request message refers to the time delay from when the sensing request message is sent by the sensing requester to when the sensing result is obtained. At this time, the SCF can split and set the QoS indicator sensing time delay in the sensing indication message to 50 ms, indicating the time delay from when the sensing request message is received by the SCF to when the sensing result is received by the SPF.

[0199] Optionally, the QoS indicator sensing time in the sensing request message and the QoS indicator sensing time delay in the sensing request message can be the same.

[0200] As an example, the sensing distance resolution in the sensing request message is yy, and the SCF can set the sensing distance resolution in the sensing indication message to be higher or lower than yy, for example, zz, for processing redundancy of subsequent sensing data processing.

[0201] Optionally, the perception distance resolution in the perception request message and the perception distance resolution in the perception indication message can be the same.

[0202] The other parameters (e.g., the perception angle measurement accuracy, the perception speed resolution, the perception object identification accuracy, or the perception object identification false alarm rate) are similar, and will not be described one by one.

[0203] For example, the distance resolution: yy=0.5m, zz=0.4m; the angle measurement accuracy: yy=0.5 degrees, zz=0.4 degrees; the speed resolution: yy=0.5m / s, zz=0.4m / s; the identification accuracy: yy=90%, zz=91%; the identification false alarm rate: yy=5%, zz=4%. yy represents the information in the perception request message, and zz represents the information in the perception indication message.

[0204] When the perception device includes a UE, the SCF can send the perception indication message to the UE through the network device.

[0205] S240, the perception device obtains the perception data.

[0206] For example, the perception device performs perception based on the perception requirement in the perception indication information to obtain the perception data.

[0207] For example, the UE performs perception on the information around the UE based on the indication of the perception indication message. For example, the UE performs perception on the human body shape, contour, and motion within 50 meters around the UE for automatic driving assistance; the UE performs perception on the human body, breathing, and heartbeat.

[0208] S250, the perception device sends the perception data to the SPF. Correspondingly, the SPF receives the perception data.

[0209] When the perception device includes a UE, in some implementations, the UE sends the perception data to the SPF through the network device.

[0210] S260, the SPF processes the perception data to obtain the perception result.

[0211] S270, the SPF sends the perception result to the SCF and the perception requester.

[0212] In some implementations, the SPF not only sends the perception result, but also sends an actual completion index of the perception result, which can be referred to as a perception service quality guarantee index.

[0213] In some implementations, the content contained in the perception service quality guarantee index can refer to the perception service quality index. For example, the perception service quality guarantee index can contain at least one index in the perception service quality index.

[0214] As an example, the perception service quality assurance indicator includes at least one of the following indicators: a perception speed range, a perception distance resolution, a perception angle accuracy, a perception speed resolution, a perception QoS indicator, a perception location point, a perception UE identification, a perception object identification accuracy, a perception object identification false alarm rate, a perception data accuracy, a perception data update frequency, a minimum radar cross section, or a perception dimension.

[0215] In some implementations, one or more of the perception service quality indicators are considered desired indicators, and the perception service quality assurance indicator is considered to be an actual achieved value of the one or more of the perception service quality indicators. In this implementation, the perception service quality assurance indicator can not be equal to the value of the same indicator in the perception service quality indicators.

[0216] For example, the perception distance resolution in the perception request message or the perception indication message is 10 meters, but the perception device actually achieves a perception distance resolution of only 8 meters when performing perception, and thus the perception distance resolution in the perception service quality assurance indicator in the billing information is 8 meters.

[0217] In some implementations, the perception service quality assurance indicator can be equal to the value of the same indicator in the perception service quality indicators.

[0218] It can be understood that the steps included in this embodiment are only examples, and fewer or more steps can be included in the embodiments of the present application, or one or more of the steps can be replaced by other functionally similar steps.

[0219] FIG. 3 is an exemplary structure diagram of a communication system according to an embodiment of the present application. The system shown in FIG. 3 differs from the system shown in FIG. 1 in that the system shown in FIG. 3 can further include a CHF and a billing device. The CHF is a short form of a CHF entity.

[0220] The CHF entity is an entity within a core network domain, subsystem, or service that participates in the billing of the domain, subsystem, or service. For example, it collects, formats, transmits, and evaluates information related to a charging event in order to be able to determine that a charged party can be billed (offline charging) or that a user's account balance can be debited (online charging).

[0221] The billing device is typically part of an operator's network, located outside the core network, and is used to receive and process charging data record (CDR) files from the charging function. The billing device includes functions that can provide billing mediation and charging or other (e.g., statistical) end applications. In some implementations, the billing device is suitable for offline charging.

[0222] Based on the system architecture shown in FIG. 3, the charging function of the wireless sensing service can be implemented.

[0223] FIG. 4 is an exemplary flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 4, the method can include S410, S420 and S430. The steps in the method shown in FIG. 4 can be located after the steps in the method shown in FIG. 2.

[0224] At S410, the sensing control function entity determines charging information, which is used for charging the wireless sensing service.

[0225] The charging information in the embodiment can be referred to as charging information of the wireless sensing service.

[0226] In some implementations, the charging information includes an identifier of the wireless sensing service, to inform the billing device to charge for the wireless sensing service.

[0227] In some implementations, the identifier of the wireless sensing service is assigned by the SCF for the wireless sensing service.

[0228] In some implementations, the charging information includes at least one of the following information related to the wireless sensing service: an identifier of a sensing requester, an identifier of an AF, a sensing event, a sensing mode, a sensing type, a flow of sensing data, a flow of sensing result, a sensing duration, a sensing area, a number of sensing targets, or a quality of service guarantee index of the sensing service.

[0229] In some implementations, when the sensing requester is an AF, the identifier of the sensing requester and the identifier of the AF can be the same identifier, or can only include one of them.

[0230] In some implementations, the sensing area includes a number of network devices participating in the sensing.

[0231] In some implementations, what information is included in the charging information can depend on the charging mode of the wireless sensing service.

[0232] For example, if the charging mode of the wireless sensing service includes charging based on the flow of sensing data, the flow of sensing data is included in the charging information; if the charging mode of the wireless sensing service includes charging based on the sensing duration, the sensing duration is included in the charging information; if the charging mode of the wireless sensing service includes charging based on the number of sensing devices, the sensing area is included in the charging information; if the charging mode of the wireless sensing service includes charging based on the quality of service guarantee index of the sensing service, the quality of service guarantee index of the sensing service can be included in the charging information; if the cost information of different sensing events is different, the sensing event is included in the charging information. The functions of other charging information are similar, which will not be described here.

[0233] In some embodiments, the charging manner can be determined based on all or part of the information in the charging information.

[0234] As an example, the sensing type can be used to determine the charging mode, or in other words, the charging mode is determined based on the sensing type. For example, different sensing types can select different charging modes. For example, target area monitoring sensing type can select duration charging, target area object imaging sensing type can select charging mode based on the number of sensing objects, target area object speed measurement sensing type can select charging mode based on the number of base stations, and so on.

[0235] S420, the perception control function entity sends charging information to the charging function entity. Correspondingly, the charging function entity receives the charging information from the perception control function entity.

[0236] In some embodiments, the perception control function entity triggers the charging process after receiving the event of the sensing result, that is, the perception control function entity sends charging information to the charging function entity.

[0237] In some embodiments, the perception control function entity sends the charging information through a charging data request.

[0238] In some embodiments, the perception control function entity sends the charging information through the Nchf service interface.

[0239] S430, the charging function entity generates a charging data record, and the charging data record contains the charging information. Correspondingly, the charging device receives the charging data record.

[0240] The charging device in the embodiments of the present application can also be referred to as a billing device, and the related content can refer to the content of the aforementioned billing device.

[0241] The charging data record in the embodiments of the present application can be referred to as a charging bill. The charging bill of the wireless sensing service can include a plurality of fields, and the plurality of fields one-to-one correspond to a plurality of information in the charging information. The fields of the charging bill of the wireless sensing service are shown in Table 2. It can be understood that the order of the fields in Table 2 is only an example.

[0242] Table 2 Fields of the charging bill of the wireless sensing service

[0243] In the embodiment, the charging information is obtained by the perception control function entity, and the charging information is sent to the charging function entity, and then the charging function entity generates a charging data record based on the charging information, so as to facilitate the charging of the wireless sensing service, thereby supporting the benign supply of the wireless sensing service.

[0244] In some implementations of the embodiment, at least one of the information in the charging information is determined by the perception control function based on information received from the perception processing function entity.

[0245] For example, the perception control function entity receives perception information from the perception processing function entity, the perception information including at least one of the following information: traffic of the perception data, traffic of the perception result, number of the perception target, or, quality of service assurance index of the perception service; the perception control function entity determines the charging information according to the perception information, i.e., all or part of the perception information is taken as the charging information.

[0246] In some implementations of the embodiment, at least one of the information in the charging information is determined by the perception control function based on information in the perception request message sent by the perception requester.

[0247] For example, the perception control function entity receives the perception service request message, the perception service request message including at least one of the following information: perception duration, AF identifier, perception event, perception mode, or perception type; the perception control function entity determines the charging information according to the perception service request message, i.e., all or part of the information in the perception service request message is taken as the charging information.

[0248] In some implementations of the embodiment, at least one of the information in the charging information is determined by the perception control function itself.
