The present application does not make any restrictions in this regard.

[0080] Second, in the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally represents an "or" relationship between the associated objects before and after. "At least one (item)" or its similar expression refers to any combination of these items, including any combination of a single item or multiple items. For example, at least one (item) of a, b, and c can represent: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Where a, b, and c can be single or multiple respectively.

[0081] Third, in the present application, "first", "second", and various numerical numbers are for the convenience of description and are not used to limit the scope of the embodiments of the present application. For example, to distinguish different messages, etc., rather than for describing a specific order or sequence. It should be understood that the objects described in this way can be interchanged under appropriate circumstances so as to be able to describe the solutions other than the embodiments of the present application.

[0082] Fourth, in the present application, the terms "include" and "have" and any of their variations are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0083] Fifth, in the present application, "for indicating" can include for direct indication and for indirect indication. When describing that a certain indication information is used to indicate A, it can include that the indication information directly indicates A or indirectly indicates A, and it does not mean that A must be carried in the indication information.

[0084] Sixth, in this application, "sending information to XX (device / network element)" can be understood as the destination of the information being this device. It can include sending information to this device directly or indirectly. "Receiving information from XX (device / network element), or receiving information coming from XX (device / network element)" can be understood as the source of the information being this device, and it can include receiving information from this device directly or indirectly. Necessary processing may be performed on the information between the source and the destination of the information sending, such as format change, etc., but the destination can be understood as the valid information from the source.

Among them, a base station is a device deployed in a radio access network that can provide wireless communication functions, and it can also be called a base station device. For example, the evolved base station (evolutional Node B, eNB or e-NodeB) in the LTE system, Node B, the base station in the 5G system (gNodeB or gNB), the base station in the 6G system, etc. A base station can include a BBU and a remote radio unit (RRU). The BBU and the RRU can be placed in different locations. For example, the RRU is remote and placed in a high-traffic area, and the BBU is placed in the central computer room. The BBU and the RRU can also be placed in the same computer room. The BBU and the RRU can also be different components under a single rack. A base station can be in the following forms: macro base station, micro base station (also called small cell), pico base station, relay station, access point, balloon station, etc. Optionally, in some deployments of the access network devices, the access network devices can include a central unit (CU) and a distributed unit (DU), etc. In some other deployments of the access network devices, the CU can also be divided into CU-control plane (CP) and CU-user plane (UP), etc. In some other deployments of the access network devices, the access network devices can also be an open radio access network (ORAN) architecture, etc. This application does not limit the specific deployment methods of the access network devices.

[0092] The AMF network element is responsible for the mobility management of the terminal device, including mobility status management, allocating a temporary identity identifier for the terminal device, and authenticating and authorizing the terminal device.

[0093] The SMF network element is responsible for user plane network element selection, user plane network element reselection, Internet Protocol (IP) address allocation, and is also responsible for the establishment, modification, and release of bearers, as well as for Quality of Service (QoS) control. In the 5G system, the interface used for communication between the SMF network element and the UPF network element is the N4 interface, and its specific functions include: configuring the details of data forwarding for PDU sessions (such as forwarding rules, QoS guarantee rules, etc.), event reporting, network element-level configuration information interaction, etc.

[0094] The UDM network element is responsible for managing subscription data and notifying the corresponding network elements when the subscription data is modified.

[0095] The UDR network element is used to store and retrieve subscription data, policy data, and common architecture data, etc.; it is also used for the UDM network element, PCF network element, and NEF network element to obtain relevant data. The UDR network element should be able to have different data access authentication mechanisms for different types of data such as subscription data and policy data to ensure the security of data access; the UDR network element should be able to return a failure response with an appropriate cause value for illegal service operation or data access requests.

[0096] The AF network element is used to provide a certain application layer service to the terminal device. When the AF network element provides a service to the terminal device, it has requirements for QoS policy and charging policy and needs to notify the network. At the same time, the AF network element also needs application-related information fed back by the core network.

[0097] The UPF network element supports all or part of the following functions: interconnecting the PDU session with the data network, packet routing and forwarding, and packet detection. Among them, the UPF network element supports packet routing and forwarding. For example, the UPF network element supports classifying the uplink traffic by the uplink classifier (UL CL) and then forwarding it to the data network, and supports the branching point to support multi-homed PDU sessions.

[0098] Please refer to Figure 3 , Figure 3It is a schematic diagram of a communication system provided by an embodiment of this application. The communication system includes a sensing device and a sensing function (SF) network element. Among them, the sensing device is a device that performs sensing. The sensing device can send sensing signals and receive the signals reflected by the sensing signals. The sensing signal is a signal used for sensing. The sensing device can be, for example, a terminal device or an access network device. The embodiment of this application is not limited to the naming of "sensing device", and other names can also be used. For example, "sensing device" can also be replaced by "sensing entity". For the convenience of description, the following will take "sensing device" as an example for description.

[0099] The SF supports the following partial or all functions: session management function for sensing data transmission (for example, determining the QoS for transmitting sensing data, etc.), managing sensing accuracy parameters (for example, obtaining the corresponding and network-side processable sensing accuracy according to the requirements of the AF network element), and processing of sensing data (for example, converting sensing measurement data into the final target result information of sensing).

[0100] It should be noted that the SF network element can be one of the network elements in the core network or a non-core network element. This application does not make special limitations on this. When the SF network element is one of the network elements in the core network, the SF network element can be connected to other network elements in the core network through a service-based architecture (SBA) interface, that is, it can communicate with other network elements in the core network through the SBA interface. When the SF network element is a non-core network element, the SF network element may not be connected to other network elements in the core network through the SBA interface. In this case, it may be necessary to interact with other core network elements through the relay of the NEF network element.

[0101] In a possible implementation, the SF network element can be separated into a control plane and a user plane, that is, the SF control plane (SF-C) function and the SF user plane (SF-U) function are separated. Among them, the SF-C can send control commands to the access network device through the control plane; the SF-U can receive sensing data from the access network device through the data plane and optionally process the sensing data to obtain a sensing result.

[0102] In addition, the SF network element can be an independent network element, and the SF network element can communicate with other network elements / devices through external interfaces. Alternatively, SF can be a logical function of other network elements. For example, SF can be one of the logical functions of a location management function (LMF) network element. Alternatively, SF can also be co-located with other functions. The naming of the co-located network element is not limited in this application. For example, SF can be co-located with the SMF and / or UPF, and the co-located network element is named the SF network element or other names. Based on actual needs, SF can also be other possible situations, which are not limited. For ease of description, the SF network element is used as an example in the following description. The SF network element is an independent network element, or the SF network element is a network element obtained by co-locating SF with other functions. The situation where SF is a logical function of other network elements is similar. In this case, the operations performed by the SF network element in the following text are replaced by the network element to which SF belongs, and will not be elaborated further.

[0103] It can be understood that the embodiments of this application are described by taking the 5G system as an example. When the solutions of the embodiments of this application are applied to the 6G or other communication systems, the corresponding network element names, network element deployment methods, interfaces, etc. may change, and this application does not make any limitations in this regard.

[0104] The following elaborates on the relevant concepts involved in the embodiments of this application.

[0105] 1. Process of establishing a sensing service

[0106] After obtaining the first request message, the SF network element can establish a sensing service. The first request message is used to request the establishment of a sensing service. The first request message may include one or more of the following: target area information of the sensing, sensing service requirement information, address information of the AF network element, start time of the sensing service. Among them, the sensing service requirement information includes one or more of the following: sensing service quality-related information, sensing data transmission control-related information, or sensing data-related information.

[0107] Among them, the sensing service quality-related information includes the type of the sensing service and / or the requirements for the sensing service. Examples of the type of the sensing service are vehicle networking services, drone intrusion detection services, etc. The requirements for the sensing service include, for example, requirements for positioning accuracy, speed measurement accuracy, sensing resolution, latency, etc.

[0108] The information related to the control of the transmission of sensing data is used to indicate the requirement for the frequency of transmitting sensing data. For example, the frequency of transmitting sensing data can be to transmit sensing data once, or to transmit sensing data periodically, or to transmit sensing data in a triggered manner. Among them, transmitting sensing data in a triggered manner can be understood as: transmitting sensing data when a trigger condition is met. For example, the trigger condition for the sensing device to transmit sensing data is: obtaining information for requesting the transmission of sensing data. That is to say, the sensing device transmits sensing data when / after obtaining the information for requesting the transmission of sensing data. In addition, in the embodiments of the present application, the transmission of sensing data can be the uplink transmission of sensing data, and the uplink transmission of sensing data can also be understood as reporting sensing data. For example, if the sensing device is an access network device, the access network device transmitting sensing data can be: the access network device sending sensing data to the UPF network element or the SF network element. The UPF network element can be, for example, the sensing UPF network element (i.e., the Sensing-UPF network element), and the SF network element can be, for example, the user plane function of the SF network element (such as SF-U). Details will not be elaborated hereinafter.

[0109] The information related to the sensing data is used to indicate the requirement for the type of the transmitted sensing data. Exemplarily, the required type of sensing data is point cloud information. The point cloud information is a set composed of points on the reflection surface where the sensing signal is reflected by an object. Among them, the sensing signal is a signal used for sensing. Exemplarily, the required type of sensing data is the sensing result, and the sensing result can also be understood as the final measurement result. The final measurement result can be, for example, the description information of the measured object. For example, the description information of an event is used to describe whether there is an intruder in a given sensing area. For another example, the description information of an event is used to describe the drawn three-dimensional (3D) map. For another example, the description information of an event is used to describe the sensed target in a given sensing area (for example, if the sensed target is a vehicle, the description information of the event is used to describe the vehicle sensed in the given sensing area).

[0110] In addition, the sensed service requirement information can include other requirements for the sensing service in addition to the content already mentioned, without limitation.

[0111] In addition, the embodiments of the present application do not limit the manner in which the SF network element obtains the first request message. For example, the AF network element directly sends the first request message to the SF network element, and this manner can be applied to the case where the AF network element is located in the trust domain of the network. For another example, the AF network element sends the first request message to the SF network element through an intermediate network element (for example, the NEF network element). It should be noted that the intermediate network element may send the first request message itself received from the AF network element to the SF network element, or it may also be information generated by the intermediate network element according to the first request message sent by the AF network element. For another example, the SF network element locally configures the first request message, or the SF network element subscribes to the first request message, or the SF network element obtains the first request message through the UDM network element. For another example, the SF network element obtains the first request message through network configuration. For example, the operating and maintenance (OAM) system may provide the first request message to the SF network element.

[0112] In addition, in the embodiments of the present application, the "AF network element" can also be replaced with: "application server", "third-party application", "data collector" or "application requester", etc. For the convenience of description, the embodiments of the present application take the "AF network element" as an example for description, and will not be elaborated hereinafter.

[0113] Taking the example of the AF network element sending the first request message to the SF network element, and taking the two scenarios where the sensing device is an access network device and the sensing device is a terminal device as examples, the process of establishing a sensing service will be described exemplarily as follows in the optional methods a and b.

[0114] Method a: Scenario where the sensing device is an access network device

[0115] Combined with Figure 4, the process of establishing a sensing service includes: The AF network element sends a first request message to the SF network element; correspondingly, the SF network element receives the first request message from the AF network element. The SF network element sends a first response message to the AF network element, and the first response message includes the identification information of the sensing service; correspondingly, the AF network element receives the first response message from the SF network element. The SF network element interacts with the SMF network element to obtain relevant parameters for transmitting sensing data. The SF network element determines the sensing accuracy requirement information based on the sensing service requirement information. The SF network element sends a second request message to the access network device, and the second request message includes the sensing accuracy requirement information and the relevant parameters for transmitting sensing data; correspondingly, the access network device receives the second request message from the SF network element. The access network device determines the transmission resources allocated for the sensing service based on the second request message. The access network device sends a second response message to the SF network element, and the second response message is the response message corresponding to the second request message. The second response message may include, for example, Information #1, and Information #1 is used to indicate the transmission resources allocated for the sensing service.

[0116] After the establishment of the sensing service is completed, the access network device can collect sensing data based on the transmission resources allocated for the sensing service, and send the sensing data directly or through the UPF network element to the SF network element, and then the SF network element sends the sensing data to the AF network element. In addition, it is worth noting that what the SF network element sends (reports) to the AF network element can be the sensing data collected by the SF network element itself, or it can also be the data obtained after processing the collected sensing data by the SF network element, and this is not limited.

[0117] In the embodiments of the present application, the identification information of the sensing service may be, for example, a sensing identity (ID) (i.e., sensing ID), and the sensing ID can represent a specific sensing service (within the operator). Exemplarily, the numbering rule of the sensing ID is a combination of the operator identification and the sensing service identification. Among them, the "sensing service identification" can also be understood as the "sensing business identification". For example, the sensing ID can be expressed as: [operator identification][sensing service identification], where each field can be represented by binary, octal, decimal, or hexadecimal numbers.

[0118] In a possible implementation method, the operator pre-configures the range of sensing service identifiers that the SF network element can allocate; after the SF network element obtains the first request message, the SF network element allocates an unallocated sensing service identifier as the identification information of the sensing service. For example, taking the sensing service identifier represented by binary digits as an example, the operator pre-configures the range of sensing service identifiers that the SF network element #1 can allocate as: 000 to 111 (binary). Among 000 to 111, the unallocated sensing service identifiers are 100 to 111. Then, after the SF network element #1 obtains the first request message, the SF network element #1 can select a sensing service identifier from 100 to 111 as the identification information of the sensing service #1. For example, the SF network element #1 selects "101" from 100 to 111 as the identification information of the sensing service #1.

[0119] In the embodiments of the present application, the relevant parameters for transmitting sensing data may include, for example, QoS description information (QoS profile) for transmitting sensing data and tunnel information for transmitting sensing data. Among them, the QoS profile may include one or more of the following: QoS identifier, allocation and retention priority (ARP), guaranteed bit rate (GBR), or maximum bit rate (MBR). Among them, the QoS identifier may be, for example, a 5G QoS identifier (5G QoS identifier, 5QI). In addition, in addition to the content already mentioned, the QoS profile may also include other QoS requirements for transmitting sensing data, without limitation.

[0120] In the embodiments of the present application, in a possible implementation method, the sensing accuracy requirement information includes one or more levels of sensing accuracy requirements. This implementation manner can be applied to a scenario where the sensing service requirement information in the first request message includes one or more sensing service quality-related information. In this scenario, it can be understood that one sensing service can correspond to one or more sensing service quality-related information, and different sensing service quality-related information is not completely the same. For example, the sensing accuracy requirement information includes 2 levels of sensing accuracy requirements, as shown in Table 1 below.

[0121] Table 1

[0122]

[0123] As can be seen from Table 1, in the sensing accuracy requirements corresponding to Level 1, the requirements for the positioning estimation accuracy by sensing are: the positioning estimation accuracy by sensing ≤ 1 meter (m). The requirements for the sensing resolution are: the sensing resolution < 1 m. The requirements for the maximum sensing service latency are: the maximum sensing service latency ≤ 1000 milliseconds (ms). The requirements for the refresh rate are: the refresh rate ≤ 1 second (s). The requirements for the missed detection rate are: the missed detection rate ≤ 2%. The requirements for the false detection rate are: the false detection rate ≤ 2%.

[0124] In the sensing accuracy requirements corresponding to Level 2, the requirements for the positioning estimation accuracy by sensing are: the positioning estimation accuracy by sensing ≤ 5 m. The requirements for the sensing resolution are: the sensing resolution < 5 m. The requirements for the maximum sensing service latency are: the maximum sensing service latency < 1000 ms. The requirements for the refresh rate are: the refresh rate < 1 s. The requirements for the missed detection rate are: the missed detection rate ≤ 5%. The requirements for the false detection rate are: the false detection rate ≤ 2%.

[0125] Optionally, in the case where the sensing accuracy requirement information includes sensing accuracy requirements at multiple levels, the access network device can adjust the adopted sensing accuracy requirements by itself. For example, referring to Table 1, the access network device allocates transmission resource #1 for the sensing service based on the sensing accuracy requirements at Level 1; subsequently, the access network device finds that transmission resource #1 cannot meet the sensing accuracy requirements at Level 1, and the access network device adjusts the adopted sensing accuracy requirements to the sensing accuracy requirements at Level 2, but the access network device can not change the transmission resources allocated for the sensing service, that is, the transmission resources allocated for the sensing service are still transmission resource #1.

[0126] Method b: The scenario where the sensing device is a terminal device

[0127] Combined with Figure 5 , the process of establishing a sensing service includes: The AF network element sends a first request message to the SF network element; correspondingly, the SF network element receives the first request message from the AF network element. The SF network element sends a first response message to the AF network element, and the first response message includes the identification information of the sensing service; correspondingly, the AF network element receives the first response message from the SF network element. The AF network element or the SF network element determines the sensing terminal device. The AF network element or the SF network element sends to the sensing terminal device: the identification information of the sensing service, the accuracy requirement information of the sensing service. In addition, the network also establishes a channel for transmitting sensing data, and this channel is used for the terminal device to send sensing data to the AF network element through the UPF network element and the SF network element.

[0128] Among them, the AF network element or the SF network element determines the sensed terminal device. For example, it can be that the AF network element or the SF network element determines the sensed terminal device based on the target area information sensed in the first request message. In addition, for the specific description of the identification information of the sensing service, please refer to the relevant description in Method a. The accuracy requirement information of the sensing service can include, for example, positioning accuracy information, speed measurement accuracy information, sensing resolution, latency, etc. The accuracy requirement information of the sensing service can also refer to the relevant description of the sensing accuracy requirement information in Method a, which will not be elaborated here. In addition, the AF network element or the SF network element sending information to the sensed terminal device can be directly sent to the terminal device, or can also be sent to the terminal device through an intermediate network element (for example, the access network device where the terminal device camps), without limitation.

[0129] After the sensing service is established, the terminal device can collect sensing data and send the sensing data to the UPF network element. The UPF network element sends the sensing data to the SF network element, and then the SF network element sends the sensing data to the AF network element. In addition, it is worth noting that what the SF network element sends ( / reports) to the AF network element can be the sensing data itself collected by the SF network element, or can also be the data obtained after processing the collected sensing data by the SF network element, without limitation in this regard. The SF network element can report the sensing data through the user plane (for example, SF-U), or can also report the sensing data through the control plane (for example, SF-C), without limitation in this regard.

[0130] In addition, the information transmission method described in the embodiments of the present application can be applied to the scenario where the sensing service is established. The above Method a and Method b are only exemplary descriptions of the process of establishing the sensing service. In the scenario where the information transmission method described in the embodiments of the present application is applied and the sensing service is established, there is no limitation on the specific process of establishing the sensing service.

[0131] It is worth noting that the term "determine" mentioned in the embodiments of the present application can specifically refer to the specific action of "determine", or can also be replaced by "discover", without limitation in this regard.

[0132] The following elaborates on the embodiments of the present application in conjunction with the accompanying drawings. The embodiments of the present application take the SF network element, the AF network element, and the sensing device as the execution entities to illustrate the corresponding methods, but the present application does not limit the execution entities of the methods. For example, the network element / device in the method can also be a chip, a chip system, or a processor that supports the network element / device to implement the corresponding method, or can also be a logic module or software that can implement all or part of the functions of the network element / device.

[0133] Please refer to Figure 6 , Figure 6 which is a schematic flowchart of an information transmission method 100 provided by the embodiments of the present application. The information transmission method 100 includes the following steps.

[0134] S101. The SF network element determines the transmission resources that need to be adjusted for the perception service based on the first information and the requirements for the perception service.

[0135] The first information includes one or more of the following: error event information, error event ratio, or performance parameters that do not meet the requirements, and the first information is determined based on the perception data corresponding to the perception service.

[0136] In addition, in the embodiments of the present application, the perception data may correspond to one perception service, or may also correspond to multiple perception services. The perception data may be obtained by the perception device through perception and collection for the perception service, or the perception data may also be obtained by the perception device through perception and collection based on its own capabilities and then used for the perception service, and this is not limited.

[0137] In addition, in the embodiments of the present application, the perception data may be, for example, point cloud information, and the perception data may also be, for example, a perception result. In addition, for the case where the perception data is not a perception result (for example, the perception data is point cloud information), a perception result can be determined based on the perception data. For the specific elaboration of point cloud information and perception results, reference can also be made to the foregoing related elaboration and will not be repeated here.

[0138] In an alternative embodiment, the error event information includes error events. Optionally, the error event information further includes the time information corresponding to the error event. The time information corresponding to the error event may be represented by a specific moment, for example, or may also be represented by a time identifier. The time identifier in the time information corresponding to the error event may be, for example, the serial number of the time window to which the error event belongs, or may also be the serial number of the time series to which the error event belongs. The embodiments of the present application do not limit the representation method of the time information.

[0139] Optionally, the error event includes one or more of the following: undetected event, misdetected event, or inaccurate perception accuracy event. Exemplarily, the undetected event may be manifested as: the perceived target is not perceived. For example, if the perceived target is a vehicle and the actual vehicle #1 is not perceived, it indicates that vehicle #1 has been undetected. Exemplarily, the misdetected event may be manifested as: a non-perceived target is perceived as a perceived target. For example, if the perceived target is a motor vehicle and vehicle #1 is perceived, but vehicle #1 is actually a non-motor vehicle, it indicates that vehicle #1 has been misdetected. Exemplarily, the misdetected event may also be manifested as: a perceived target is perceived in a scenario where the perceived target does not exist. For example, if the perceived target is a vehicle and there are actually only vehicle #1 and vehicle #2, but vehicle #1, vehicle #2, and vehicle #3 are perceived, it indicates that vehicle #3 has been misdetected. The misdetected event may also be referred to as a wrong detection event. Additionally, the error event may include other types of events in addition to the events already mentioned, and there is no limitation on this.

[0140] An exemplary elaboration of the error event is described below, as described in the following optional Embodiment 1.1 to Embodiment 1.4.

[0141] In Embodiment 1.1, the error event is determined by comparing the perception data (or the perception result obtained based on the perception data) with the information obtained through other means (for example, the information obtained through a camera, etc.).

[0142] For example, taking the perceived target as a vehicle and the perceived area as Area #1 as an example, based on the perception data, it is determined that at time #1, vehicle #1 and vehicle #2 are perceived within Area #1. The picture taken by the camera shows that at time #1, vehicle #1, vehicle #2, and vehicle #3 are within Area #1. Then, the fact that vehicle #3 within Area #1 is not perceived at time #1 belongs to an undetected event.

[0143] In Embodiment 1.2, the error event is determined by comparing the information in the perception data (or the perception result obtained based on the perception data) with a time granularity.

[0144] For example, taking the perceived target as a vehicle and the perceived area as Area #1 as an example, based on the perception data, it is determined that at time #1, vehicle #1, vehicle #2, vehicle #3, vehicle #4, and vehicle #5 are perceived within Area #1; at time #2, vehicle #1, vehicle #2, vehicle #3, and vehicle #5 are perceived within Area #1; at time #3, vehicle #1, vehicle #2, vehicle #3, vehicle #4, and vehicle #5 are perceived within Area #1. It can be seen that vehicle #4 is perceived at both time #1 and time #3, but vehicle #4 is not perceived at time #2. Then, it can be determined that the fact that vehicle #4 is not perceived at time #2 belongs to an undetected event, and the time information corresponding to this undetected event is, for example, time #2.

[0145] For another example, taking the perception target as a vehicle and the perception area as Area #1 as an example, based on the perception data, it is determined that at Time #1, Time #2, Time #4, Time #5, and Time #6, only Vehicle #1, Vehicle #2, Vehicle #3, and Vehicle #4 are perceived. At Time #3, in addition to Vehicle #1, Vehicle #2, Vehicle #3, and Vehicle #4, Vehicle #5 is also perceived. It can be seen that Vehicle #5 is not perceived at Time #1, Time #2, Time #4, Time #5, and Time #6, but Vehicle #5 is perceived at Time #3. Then, it can be determined that the perception of Vehicle #5 at Time #3 belongs to a misdetection event, and the time information corresponding to this misdetection event is, for example, Time #3.

[0146] Embodiment 1.3, the error event is determined by comparing the perception data (or the perception result obtained based on the perception data) with historical information. Among them, the historical information can be, for example, the previously recorded perception data or perception result.

[0147] For example, based on historical information, it is determined that at 9:00 and 10:00 every morning from the 1st day to the 15th day, there is Vehicle #1 in Area #1. Based on the perception data, it is determined that at 9:00 in the morning on the 16th day, Vehicle #1 is not perceived in Area #1, and at 10:00 in the morning on the 16th day, Vehicle #1 is perceived in Area #1. Then, it can be determined that the non-perception of Vehicle #1 in Area #1 at 9:00 in the morning on the 16th day belongs to an undetected event.

[0148] Embodiment 1.4, the error event is determined by comparing the perception data (or the perception result obtained based on the perception data) with the information obtained based on user feedback.

[0149] For example, based on the perception data, it is determined that at Time #1, a car accident is not perceived in Road Section #1. Based on the information obtained from user feedback, it is determined that at Time #1, a car accident occurred in Road Section #1. Then, it can be determined that the non-perception of a car accident in Road Section #1 at Time #1 belongs to an undetected event.

[0150] For another example, based on the perception data, it is determined that at Time #1, a car accident is perceived in the left lane of Road Section #1. Based on the information obtained from user feedback, it is determined that at Time #1, a car accident occurred in the right lane of Road Section #1. Then, it can be determined that the perception of a car accident in the left lane of Road Section #1 at Time #1 belongs to a misdetection event.

[0151] In addition, the error event can be determined based on one or more of the above Embodiment 1.1 to Embodiment 1.4, or it can also be determined based on other methods, or it can also be a combination of one or more of the above Embodiment 1.1 to Embodiment 1.4 and other methods. There is no limitation on the determination method of the error event in the embodiments of the present application.

[0152] In an alternative embodiment, the error event ratio is the ratio of error events. Understandably, based on the error events, the error event ratio can be determined. Exemplarily, the error event ratio can be: the ratio of error events in a number of consecutive perceptions. Exemplarily, the error event ratio can be: the ratio of error events in a measurement window, and the measurement window can be, for example, a predefined (or configured or determined in other ways) time window. Optionally, the error event ratio includes one or more of the following: the ratio of missed detection events, the ratio of false detection events, or the ratio of inaccurate sensing accuracy events, where the ratio of missed detection events can also be understood as the missed detection rate, and the ratio of false detection events can also be understood as the false detection rate. Additionally, in addition to what has been mentioned, the error event ratio can also include other types of event ratios, and no limitation is imposed thereon.

[0153] For example, measurement window #1 includes 20 time series, and 2 of these 20 time series have missed detection events. Then, the ratio of missed detection events is 10%. 3 of these 20 time series have false detection events. Then, the ratio of false detection events is 15%.

[0154] In an alternative embodiment, the performance parameter that does not meet the requirements is the performance parameter that does not meet the requirements for the sensing service. The performance parameter that does not meet the requirements can be one or more. Exemplarily, the performance parameter can be the accuracy of positioning estimate by sensing, sensing resolution, max sensing service latency, refresh rate, missed detection rate, or false detection rate, etc. Additionally, in addition to the performance parameters that have been mentioned, it can also be other performance parameters, and the embodiments of the present application do not limit the type of performance parameter.

[0155] Optionally, the performance parameter that does not meet the requirements can be determined based on the requirements for the sensing service and the error event information or error event ratio. For example, for the sensing service of unmanned aerial vehicle (UAV) intrusion detection, the requirement for the missed detection rate is: the missed detection rate is less than 5%. For instance, measurement window #1 includes 20 time series, and 2 of these 20 time series have missed detection events. It can be seen that the ratio of missed detection events is 10%, and the missed detection rate does not meet the requirements. Then, the performance parameter that does not meet the requirements includes the missed detection rate. Also, for example, measurement window #2 includes 40 time series, and 1 of these 40 time series has a missed detection event. It can be seen that the ratio of missed detection events is 2.5%, and the missed detection rate meets the requirements. Then, the performance parameter that does not meet the requirements does not include the missed detection rate.

[0156] In addition, in the embodiments of the present application, in addition to the content mentioned above, the first information may further include other information determined based on the sensing data; for example, it may further include other information obtained by analyzing or processing the sensing data. For example, it may further include specific values of performance parameters that do not meet the requirements. There is no limitation thereto.

[0157] The following gives an exemplary description of the manner of obtaining the first information, as described in the following optional Embodiment 2.1 and Embodiment 2.2.

[0158] Embodiment 2.1, the method further includes: the AF network element sends the first information to the SF network element; correspondingly, the SF network element receives the first information from the AF network element.

[0159] For example, after the SF network element receives the sensing data from the sensing device, it sends the sensing data to the AF network element. The AF network element determines whether the sensing result is incorrect based on the sensing data. If the AF network element determines that the sensing result is incorrect, the AF network element sends the first information to the SF network element. Herein, whether the sensing result is incorrect may also be understood as: whether the sensing result is accurate. Optionally, the AF network element determines whether the sensing result is incorrect based on the sensing data, including: the AF network element determines whether there is an error event based on the sensing data; if there is an error event, the sensing result is incorrect. It can be understood that if the AF network element determines that there is an error event based on the sensing data, it can be considered that the sensing data is inaccurate, and thus the sensing result is considered incorrect. In addition, for the specific description of the manner of determining the error event and the manner of determining the first information, reference may be made to the relevant description above, and details are not described herein again.

[0160] In addition, the embodiments of the present application do not limit the frequency of the "AF network element sending the first information to the SF network element". For example, the AF network element may send the first information to the SF network element periodically, or may also send the first information to the SF network element aperiodically, or may also send the first information to the SF network element when a trigger condition is met. The following gives an exemplary description.

[0161] For example, the AF network element sends the first information to the SF network element at a period of t0. The AF network element determines the first information #1 based on the sensed data obtained within the time period from t to t+t0, and the AF network element sends the first information #1 to the SF network element at the moment of t+t0 (or near the moment of t+t0). The AF network element determines the first information #2 based on the sensed data obtained within the time period from t+t0 to t+2t0, and the AF network element sends the first information #2 to the SF network element at the moment of t+2t0 (or near the moment of t+2t0). The AF network element determines the first information #3 based on the sensed data obtained within the time period from t+2t0 to t+3t0, and the AF network element sends the first information #3 to the SF network element at the moment of t+3t0 (or near the moment of t+3t0); and so on.

[0162] For another example, every time the AF network element determines M error events, it performs an operation of sending the first information including the M error events to the SF network element, where M is a positive integer. For example, when M equals 1, the AF network element determines the error event #1, and the AF network element sends the first information #1 to the SF network element, and the first information #1 includes the error event #1. After that, the AF network element determines the error event #2, and the AF network element sends the first information #2 to the SF network element, and the first information #2 includes the error event #2.

[0163] Optionally, the method further includes: the AF network element sends the identification information of the sensing service to the SF network element; correspondingly, the SF network element receives the identification information of the sensing service from the AF network element. This way enables the SF network element to know the sensing service corresponding to the first information. Exemplarily, if the AF network element determines that the sensing result is incorrect based on the sensed data corresponding to the sensing service, the AF network element sends the first information and the identification information of the sensing service to the SF network element. Optionally, the identification information of the sensing service may be determined by the SF network element during the establishment of the sensing service. For the identification information of the sensing service and the process of establishing the sensing service, refer to the foregoing related descriptions, which will not be elaborated here.

[0164] Optionally, the method further includes: the AF network element sends the seventh information to the SF network element, and the seventh information is used to request information for adjusting the transmission resources allocated to the sensing service. It can be understood that even if the SF network element receives the seventh information, the SF network element can still perform the operation of "determining the transmission resources that need to be adjusted for the sensing service based on the first information and the requirements for the sensing service".

[0165] In addition, one or more of the following sent by the AF network element to the SF network element: the first information, the identification information of the sensing service, or the seventh information, for example, may be carried in the sensing service notification message sent by the AF network element to the SF network element, and the sensing service notification message may be, for example, a sensing service update request (Nsf_SensingSession_UpdateRequest) message.

[0166] In addition, in the embodiments of the present application, when the AF network element sends information (such as the first information, the identification information of the sensing service, the seventh information, etc.) to the SF network element, it can be directly sent by the AF network element to the SF network element, and this method can be applied to the case where the AF network element is located in the trusted domain of the network. Alternatively, when the AF network element sends information (such as the first information, the identification information of the sensing service, the seventh information, etc.) to the SF network element, it can also be sent by the AF network element to the SF network element through an intermediate network element (such as the NEF network element). It should be noted that what the intermediate network element sends to the SF network element can be the information itself received from the AF network element by the intermediate network element, or it can also be the information generated by the intermediate network element according to the information sent by the AF network element. Details will not be elaborated hereinafter.

[0167] Optionally, the method further includes: the SF network element sends response information to the AF network element, and the response information is used to indicate that the SF network element has received the first information. Optionally, in the scenario where the AF network element also sends the identification information of the sensing service and / or the seventh information to the SF network element, the response message can also be used to indicate that the SF network element has received the identification information of the sensing service and / or the seventh information. The response message can be, for example, a sensing service update response (Nsf_SensingSession_Update Response) message.

[0168] Embodiment 2.2: The method further includes: the SF network element determines the first information based on the sensing data corresponding to the sensing service. This embodiment can be applied to the case where the SF network element has the ability to determine the sensing result based on the sensing data. In this case, the SF network element can determine the sensing result based on the sensing data (for example, if the sensing data is point cloud information, the SF network element can determine the sensing result based on the point cloud information), so that the SF network element can determine the first information based on the sensing result. In addition, for the specific description of the determination method of the first information, reference can be made to the relevant description above, and details will not be elaborated.

[0169] In an alternative embodiment, the SF network element determines the transmission resources to be allocated to the sensing service based on the first information and the requirements for the sensing service, including: the SF network element determines whether the requirements for the sensing service are met based on the first information and the requirements for the sensing service; if the requirements for the sensing service are not met, it determines the transmission resources to be allocated to the sensing service that need to be adjusted.

[0170] In addition, in the embodiments of the present application, that the requirements for the sensing service are met can also be understood as: all the requirements for the sensing service are met. That the requirements for the sensing service are not met can also be understood as: some or all of the requirements for the sensing service are not met. For example, the requirements for sensing service #1 are: the requirements for the missed detection rate corresponding to sensing service #1, the requirements for the false detection rate corresponding to sensing service #1, and the requirements for the refresh rate corresponding to sensing service #1. That the requirements for sensing service #1 are met can also be understood as: the requirements for the missed detection rate, false detection rate, and refresh rate corresponding to sensing service #1 are all met. That the requirements for sensing service #1 are not met can also be understood as: the requirements for one or more of the missed detection rate, false detection rate, and refresh rate corresponding to sensing service #1 are not met.

[0171] In addition, in the embodiments of the present application, in the scenario where the requirements for the sensing service are not met, the transmission resources allocated to the sensing service can be adjusted to: increase the transmission resources allocated to the sensing service. It can be understood that in the scenario where the requirements for the sensing service are not met, by increasing the transmission resources allocated to the sensing service, it is beneficial to meet the requirements for the sensing service.

[0172] In addition, in the embodiments of the present application, the transmission resources can include: resources for sending sensing signals and / or resources for receiving reflected signals corresponding to the sensing signals. Among them, the transmission resources can be, for example, time-domain resources and / or frequency-domain resources and / or space-domain resources, and can also be resources in other domains, which are not limited herein. The transmission resources can also be understood as air interface resources. This will not be elaborated further hereinafter.

[0173] The following is an exemplary elaboration of the specific manner in which the SF network element determines whether the requirements for the sensing service are met, as described in the following optional embodiments 3.1 to 3.3.

[0174] Embodiment 3.1: The SF network element determines whether the requirements for the sensing service are met based on the error event information and the requirements for the sensing service.

[0175] For example, the requirement for the sensing service is the requirement for the miss detection rate corresponding to the sensing service. The requirement for the miss detection rate corresponding to the sensing service is that the miss detection rate is less than or equal to 5%. For instance, measurement window #1 includes 20 time series. Based on the error event information, it is determined that actually 2 out of the 20 time series have miss detection events, and the miss detection rate is 10%. It can be seen that the miss detection rate corresponding to measurement window #1 does not meet the requirement for the miss detection rate, so it can be determined that for measurement window #1, the requirement for the sensing service is not met. Another example is that measurement window #2 includes 40 time series. Based on the error event information, it is determined that actually 1 out of the 40 time series has a miss detection event, and the miss detection rate is 2.5%. It can be seen that the miss detection rate corresponding to measurement window #2 meets the requirement for the miss detection rate, so it can be determined that for measurement window #2, the requirement for the sensing service is met.

[0176] Another example is that the error event information is sent from the AF network element to the SF network element; every time the AF network element determines an error event, it sends the error event to the SF network element. The requirement for the miss detection rate corresponding to the sensing service is that the miss detection rate is less than or equal to 5%. Measurement window #1 includes 20 time series. When the SF network element receives the second miss detection event for measurement window #1, the SF network element can determine that the requirement for the sensing service is not met.

[0177] In Embodiment 3.2, the SF network element determines whether the requirement for the sensing service is met based on the error event ratio and the requirement for the sensing service. Among them, the error event ratio may be included in the first information, or may also be determined based on the error event information in the first information.

[0178] For example, the requirement for the sensing service is the requirement for the miss detection rate corresponding to the sensing service. The requirement for the miss detection rate corresponding to the sensing service is that the miss detection rate is less than or equal to 5%. For example, for measurement window #1, the miss detection event ratio is 10%. It can be seen that the miss detection rate corresponding to measurement window #1 does not meet the requirement for the miss detection rate, so it can be determined that for measurement window #1, the requirement for the sensing service is not met. Another example is that for measurement window #2, the miss detection event ratio is 2.5%. It can be seen that the miss detection rate corresponding to measurement window #2 meets the requirement for the miss detection rate, so it can be determined that for measurement window #2, the requirement for the sensing service is met.

[0179] Embodiment 3.3. The SF network element determines whether the requirements for the sensing service are met based on the performance parameters that do not meet the requirements and the requirements for the sensing service. It can be understood that if the performance parameters that do not meet the requirements in the first information are not default, it indicates that there are performance parameters that do not meet the requirements, so it can be determined that the requirements for the sensing service are not met. Exemplarily, in the scenario where the first information is sent from the AF network element to the SF network element, if the performance parameters that do not meet the requirements in the first information received by the SF network element from the AF network element are not default, the SF network element can determine that there are performance parameters that do not meet the requirements, and thus determine that the requirements for the sensing service are not met.

[0180] In addition, in an alternative manner, if the requirements for the sensing service are met, the SF network element may send the fifth information to the sensing device. The fifth information is used to request to reduce the transmission resources allocated for the sensing service, which helps to avoid resource waste caused by over - allocating transmission resources for the sensing service. Or, if the requirements for the sensing service are met, the SF network element may also not send the fifth information to the sensing device.

[0181] In an alternative embodiment, the SF network element may determine whether to adjust the transmission resources allocated for the sensing service based on the first information and the requirements for the sensing service; if it is necessary to adjust the transmission resources allocated for the sensing service, step S102 is executed.

[0182] S102. The SF network element sends the second information to the sensing device. The second information is used to adjust the transmission resources allocated for the sensing service. Correspondingly, the sensing device receives the second information from the SF network element.

[0183] Exemplarily, the second information is specifically used to increase the transmission resources allocated for the sensing service. This method can be applied to the scenario where the SF network element determines that it is necessary to adjust the transmission resources allocated for the sensing service when the requirements for the sensing service are not met. It can be understood that in the scenario where the requirements for the sensing service are not met, increasing the transmission resources allocated for the sensing service helps to meet the requirements for the sensing service.

[0184] In an alternative embodiment, the second information includes one or more of the following: the performance parameters that do not meet the requirements, the gap between the performance parameters that do not meet the requirements and the requirements. Optionally, the performance parameters that do not meet the requirements can be determined based on the first information. For specific elaboration, reference can be made to the foregoing related elaboration, which will not be repeated here. In addition, the second information may also include other information. For example, the second information may also include the specific values of the performance parameters that do not meet the requirements, and there is no limitation thereto.

[0185] For example, if the undetected rate determined based on the perception data is 10%, and the requirement for the undetected rate is that the undetected rate is less than or equal to 8%. Then, the second information may include: the undetected rate, 2%, indicating that the undetected rate does not meet the requirement and the difference between the undetected rate and the requirement is 2%.

[0186] Optionally, the second information further includes the identification information of the perception service. This implementation is beneficial for the perception device to determine the perception service for which the transmission resources are to be adjusted based on the identification information of the perception service. For the specific elaboration of the identification information of the perception service, reference can be made to the foregoing relevant elaboration, which will not be repeated here.

[0187] In an optional implementation, the second information is specifically used to request an adjustment of the transmission resources allocated to the perception service. It can be understood that the SF network element can request the perception device to adjust the transmission resources.

[0188] In an optional implementation, the second information is specifically used to request an adjustment of the transmission resources allocated to the perception service for a first performance parameter, where the first performance parameter is a performance parameter that does not meet the requirement. It can be understood that the SF network element can request the perception device to adjust the transmission resources for a specific performance parameter. For example, if the requirement for the undetected rate is not met, the second information can be specifically used to request an adjustment of the transmission resources allocated to the perception service for the undetected rate, so that the perception device can adjust the transmission resources allocated to the perception service for the undetected rate, making the adjusted transmission resources conducive to meeting the requirement for the undetected rate.

[0189] In an optional implementation, the SF network element sends the second information to the perception device, including: the SF network element sends the second information to the perception device through an intermediate network element. Or, the SF network element directly sends the second information to the perception device without passing through an intermediate network element.

[0190] In addition, in the embodiment of the present application, in the implementation where the SF network element sends the second information to the perception device through an intermediate network element, what the intermediate network element sends to the perception device can be the second information itself received from the SF network element, or it can also be the information generated based on the second information received from the SF network element, without limitation. For the sake of elaboration, the embodiment of the present application takes the example that what the intermediate network element sends to the perception device is the second information itself received from the SF network element for elaboration.

[0191] In an optional way, the perception device is an access network device. The SF network element sends the second information to the access network device through an intermediate network element (for example, the AMF network element). Or, the SF network element directly sends the second information to the access network device without passing through an intermediate network element.

[0192] Exemplarily, during the process of establishing a sensing service, the SF network element may record the address information or identification information of the next-hop node to which the SF network element sends the second information. For example, if the next-hop node to which the SF network element sends the second information is the AMF network element, the SF network element records the address information or identification information of the AMF network element, and the AMF network element will record the information of the access network device (for example, the identification information of the access network device, the address information of the access network device, or the tunnel identifier, etc.); among them, the address information of the AMF network element may be, for example, a callback uniform resource identifier (callbackURI), and the identification information of the AMF network element may be, for example, an AMFID or an AMF instance ID (i.e., AMF instance ID). Another example is that if the next-hop node to which the SF network element sends the second information is the access network device, the SF network element records the address information or identification information of the access network device. Among them, the address information of the access network device may be, for example, a RAN ID or an IP address, and the identification information of the access network device may be, for example, a tunnel endpoint ID (TEID).

[0193] In an alternative optional way, the sensing device is a terminal device. The SF network element sends the second information to the terminal device through an intermediate network element; or, the SF network element directly sends the second information to the terminal device without passing through an intermediate network element.

[0194] Exemplarily, the SF network element sends the second information to the terminal device through the SMF network element and the AMF network element. Specifically, the SF network element sends the second information to the SMF network element, the SMF network element sends the second information to the AMF network element, and then the AMF network element sends the second information to the terminal device. This method can be applied to the scenario where the SMF network element has subscribed to the update message of the sensing service from the SF network element in advance. In this scenario, the SF network element can determine the SMF network element, so that the SF network element can send the second information to the SMF network element.

[0195] Exemplarily, the SF network element sends the second information to the terminal device through the AMF network element. Specifically, the SF network element sends the second information to the AMF network element, and then the AMF network element sends the second information to the terminal device. This implementation method can be applied to the scenario where the SF network element can determine the identification information of the terminal device. In this scenario, the SF network element can obtain the information of the AMF network element corresponding to the terminal device based on the identification information of the terminal device. For example, the SF network element can query the information of the AMF network element corresponding to the terminal device from the UDM network element based on the identification information of the terminal device. In addition, the identification information of the terminal device may be sent by the AF network element to the SF network element.

[0196] Exemplarily, the SF network element sends the second information to the terminal device via the PCF network element, the SMF network element, and the AMF network element. Specifically, the SF network element sends the second information to the PCF network element, the PCF network element sends the second information to the SMF network element, the SMF network element sends the second information to the AMF network element, and then the AMF network element sends the second information to the terminal device.

[0197] S103. The sensing device adjusts the transmission resources allocated for the sensing service based on the second information.

[0198] Among them, the transmission resources adjusted by the sensing device for the sensing service include, for example: increasing the number of orthogonal frequency division multiplexing (OFDM) transmission symbols.

[0199] In an alternative embodiment, the sensing device is a terminal device, and the method further includes: the SF network element sends the second information to the access network device corresponding to the terminal device; correspondingly, the access network device receives the second information from the SF network element. The access network device allocates the transmission resources corresponding to the sensing service for the terminal device based on the second information. Among them, the access network device corresponding to the terminal device can be understood as: the access network device where the terminal device camps. This embodiment can be applied to the scenario where the transmission resources adopted by the terminal device are resources controlled by the operator. In this scenario, the transmission resources adopted by the terminal device are allocated for it by the access network device corresponding to the terminal device. It can be understood that the access network device adjusts the transmission resources allocated for the terminal device based on the second information, and the access network device can interact with the terminal device with information related to the transmission resources, so that the terminal device can determine the transmission resources.

[0200] In an optional manner, the method further includes: the SF network element sends the identification information of the terminal device to the access network device corresponding to the terminal device. Among them, the identification information of the terminal device can be, for example, the system architecture evolution (SAE) temporary mobile subscriber identity (TMSI) (i.e., SAE TMSI, abbreviated as S-TMSI), or the identification information of the terminal device can also be, for example, the identification of the address of the channel allocated for the terminal device by the access network device.

[0201] In an alternative optional manner, the SF network element sends second information and the identification information of the terminal device to the AMF network element. The identification information of the terminal device sent by the SF network element to the AMF network element can be, for example, the subscription permanent identifier (SUPI). Thereafter, the AMF network element sends the second information and the identification information of the terminal to the access network device corresponding to the terminal device. The identification information of the terminal device sent by the AMF network element to the access network device can be, for example, the RANUENGAPID or the AMFUENGAPID. Herein, NGAP is the next generation application protocol. In an optional implementation manner, the method further includes: the sensing device sends third information to the SF network element, and the third information is used to indicate whether the transmission resources allocated for the sensing service are successfully adjusted; correspondingly, the SF network element receives the third information from the sensing device.

[0202] In an optional implementation manner, the method further includes: the SF network element sends the sensing data obtained through the adjusted transmission resources to the AF network element; based on the sensing data obtained through the adjusted transmission resources, the AF network element determines that the sensing result is accurate or determines that the requirement for the sensing service is met, and sends the fourth information or the fifth information to the SF network element. The fourth information is used to indicate that the requirement for the sensing service is met, and the fifth information is used to request to reduce the transmission resources allocated for the sensing service. This manner can be applied to the scenario where the AF network element sends the first information to the SF network element.

[0203] Exemplarily, this manner can be applied to the scenario where the AF network element sends the first information to the SF network element (such as in Embodiment 2.1). In this scenario, after a period of time from the operation of the AF network element sending the first information to the SF network element, the AF network element receives the sensing data obtained through the adjusted transmission resources. The AF network element compares it with the information obtained through other means, or with the historical information, or with the information obtained through user feedback, and finds that the sensing result is accurate.

[0204] Alternatively, in another possible implementation manner, the AF network element can regularly count whether the sensing result determined based on the received sensing data is accurate. When the AF network element determines that the sensing result is accurate, it can send the fourth information or the fifth information to the SF network element. When the AF network element determines whether the sensing result determined based on the received sensing data is accurate, for example, it can compare the sensing result with the information obtained through other means, or with the historical information, or with the information obtained based on user feedback to determine whether the sensing result is accurate.

[0205] In an optional manner, the method further includes: the SF network element sends sixth information to the sensing device, where the sixth information is used to request a reduction in the transmission resources allocated for the sensing service; this helps to avoid resource waste caused by over-allocation of transmission resources for the sensing service. Among them, in the scenario where the SF network element receives the fifth information, the sixth information can be the same as the fifth information, or it can also be information generated based on the fifth information.

[0206] In another optional manner, in the scenario where the SF network element receives the fourth information, the SF network element may also not send the sixth information to the sensing device. This implementation can be applied when the sensing device increases the transmission resources allocated for the sensing service in step S103 in steps, and the step can be predefined or configured, without limitation. This implementation can also be applied to the scenario where the network is configured with the rule that there will be no further interaction with the sensing device when the sensing service requirements are met.

[0207] In addition, optionally, the SF network element can also determine that the requirements for the sensing service are met by combining other information. For example, if the SF network element does not receive information from the AF network element within a predefined (or network-configured or network-managed) time window and used to indicate that the requirements for the sensing service are not met, the SF network element can determine that the requirements for the sensing service are met.

[0208] In another optional implementation manner, the method further includes: the SF network element determines that the requirements for the sensing service are met based on the sensing data obtained through the adjusted transmission resources. This implementation can be applied when the SF network element has the ability to determine the sensing result based on the sensing data. In this case, the SF network element can determine the sensing result based on the sensing data, so that the SF network element can determine that the requirements for the sensing service are met based on the sensing result.

[0209] Exemplarily, this implementation can be applied to the scenario where the SF network element determines the first information based on the sensing data corresponding to the sensing service (such as in Implementation 2.2). In this scenario, after a period of time from the operation of the SF network element sending the second information to the sensing device, the SF network element receives the sensing data obtained through the adjusted transmission resources. The SF network element compares it with the information obtained through other means, or with historical information, or with the information obtained through user feedback, and finds that the sensing result is accurate.

[0210] Alternatively, in another possible implementation, the SF network element can periodically count whether the perception result determined based on the received perception data is accurate. Among them, to determine whether the perception result determined based on the received perception data is accurate, the SF network element can, for example, compare the perception result with the information obtained from other methods, or with historical information, or with the information obtained based on user feedback, to determine whether the perception result is accurate.

[0211] In an alternative way, the method further includes: the SF network element sends sixth information to the perception device, and the sixth information is used to request to reduce the transmission resources allocated for the perception service; thus, it helps to avoid resource waste caused by over-allocation of transmission resources for the perception service.

[0212] In another alternative way, the SF network element may not send the sixth information to the perception device. This implementation can be applied when the perception device increases the transmission resources allocated for the perception service in step S103 in steps, and the step can be predetermined or configured, without limitation. This implementation can also be applied to the scenario where the network is configured with the rule that when the perception service requirement is met, there will be no further interaction with the perception device.

[0213] In addition, optionally, the SF network element can also determine that the requirement for the perception service is met by combining other information. For example, if the SF network element does not identify any information indicating that the requirement for the perception service is not met within a predefined (or network-configured or network-managed) time window, the SF network element can determine that the requirement for the perception service is met.

[0214] In summary, in the information transmission method 100, the SF network element determines the transmission resources that need to be adjusted for the perception service based on the first information and the requirement for the perception service; the first information includes one or more of the following: error event information, error event ratio, or performance parameters that do not meet the requirements, and the first information is determined based on the perception data corresponding to the perception service. The SF network element sends second information to the perception device, and the second information is used to adjust the transmission resources allocated for the perception service.

[0215] It can be seen that this method can, after obtaining the perception data, determine the transmission resources that need to be adjusted for the perception service according to the first information determined based on the perception data and the requirement for the perception service, and send the second information to the perception device, which helps the perception device adjust the transmission resources allocated for the perception service, so that the perception device performs perception based on the adjusted transmission resources, which helps to meet the requirement for the perception service and further improve the perception performance.

[0216] Please refer to Figure 7 , Figure 7It is a schematic diagram of an information transmission method 200 provided by an embodiment of the present application. The information transmission method 200 includes the following steps.

[0217] S201. The AF network element determines the transmission resources that need to be adjusted for the perception service based on the first information and the requirements for the perception service.

[0218] Among them, the first information includes one or more of the following: error event information, error event ratio, or performance parameters that do not meet the requirements. The first information is determined based on the perception data corresponding to the perception service. For the specific elaboration of the first information, reference can be made to the relevant elaboration in the information transmission method 100, which will not be elaborated here.

[0219] In addition, the AF network element determines the transmission resources that need to be adjusted for the perception service based on the first information and the requirements for the perception service, which is similar to the SF network element in the information transmission method 100 determining the transmission resources that need to be adjusted for the perception service based on the first information and the requirements for the perception service. For the specific elaboration, reference can be made to the specific elaboration of the information transmission method 100, which will not be elaborated here.

[0220] In an optional manner, the AF network element can determine whether the transmission resources allocated for the perception service need to be adjusted based on the first information and the requirements for the perception service. If the transmission resources allocated for the perception service need to be adjusted, step S202 is executed.

[0221] S202. The AF network element sends the seventh information to the SF network element. The seventh information is used to request the adjustment of the transmission resources allocated for the perception service. Correspondingly, the SF network element receives the seventh information from the AF network element.

[0222] In an optional implementation manner, the seventh information is specifically used to request the adjustment of the transmission resources allocated for the perception service for the first performance parameter. The first performance parameter is the performance parameter that does not meet the requirements. This is similar to the implementation manner in the information transmission method 100 where the second information is specifically used to request the adjustment of the transmission resources allocated for the perception service for the first performance parameter. For the relevant elaboration, reference can be made to it, which will not be elaborated here.

[0223] In an optional implementation manner, the seventh information includes one or more of the following: the performance parameter that does not meet the requirements, or the gap between the performance parameter that does not meet the requirements and the requirements. For the specific elaboration of the performance parameter that does not meet the requirements and the gap between the performance parameter that does not meet the requirements and the requirements, reference can be made to the relevant elaboration in the information transmission method 100, which will not be elaborated here.

[0224] In an optional implementation manner, the seventh information is specifically used to request an increase in the transmission resources allocated for the perception service.

[0225] S203. The SF network element sends the eighth information to the sensing device, and the eighth information is used to request an adjustment of the transmission resources allocated for the sensing service. Correspondingly, the sensing device receives the eighth information from the SF network element.

[0226] Among them, the eighth information may be the same as the seventh information, or the eighth information may also be information determined ( / generated) based on the seventh information.

[0227] S204. The sensing device adjusts the transmission resources allocated for the sensing service based on the eighth information. This is similar to the sensing device adjusting the transmission resources allocated for the sensing service based on the second information in the information transmission method 100. For specific descriptions, reference can be made to the relevant descriptions of the information transmission method 100 and will not be elaborated here.

[0228] It can be seen that the difference between the information transmission method 200 and the information transmission method 100 is that in the information transmission method 200, the AF network element determines the transmission resources that need to be adjusted for the sensing service based on the first information and the requirements for the sensing service, and sends the seventh information to the SF network element to request an adjustment of the transmission resources allocated for the sensing service.

[0229] In addition, the information transmission method 200 is similar to the information transmission method 100. For specific descriptions, reference can also be made to the relevant descriptions of the information transmission method 100. The information transmission method 200 may also include the implementation manners in the information transmission method 100. For specific descriptions, refer to the relevant descriptions in the information transmission method 100 and will not be elaborated here.

[0230] In summary, after obtaining the sensing data, the information transmission method 200 can determine the transmission resources that need to be adjusted for the sensing service according to the first information determined based on the sensing data and the requirements for the sensing service, and send the seventh information to the SF network element, which is beneficial to adjusting the transmission resources allocated for the sensing service, so as to perform sensing based on the adjusted transmission resources, which is beneficial to meeting the requirements for the sensing service and further improving the sensing performance.

[0231] An embodiment of the present application also provides an information transmission method 300. The difference between the information transmission method 300 and the information transmission method 100 is that in the information transmission method 300, the SF network element or the AF network element determines the transmission resources that need to be adjusted for the sensing service based on the network statistical information in the scenario where the sensing scenario corresponding to the sensing service changes. Exemplarily, combined with Figure 8 , the information transmission method 300 includes steps S301 to S303.

[0232] S301. When the sensing scenario corresponding to the sensing service changes, the SF network element determines, based on network statistical information, the transmission resources that need to be adjusted for the sensing service. The network statistical information includes N sensing scenarios and the transmission resources respectively corresponding to the N sensing scenarios, where N is an integer greater than 1.

[0233] Among them, the sensing scenario can be, for example, a scenario of influencing factors such as weather, environment, time, etc. Or, when the sensing scenario changes, it can be that the weather, environment or time, etc. changes. In addition, the sensing scenario can also be understood as: external conditions.

[0234] The network statistical information can be, for example, information obtained based on experience (such as: empirical values). The network can determine the correspondence between the sensing scenario and the transmission resources during the deployment and debugging phase. When the sensing scenario corresponding to the sensing service changes, the SF network element can determine, based on the network statistical information, the transmission resources that need to be adjusted for the sensing service. In this case, the SF network element may not need to identify each error event.

[0235] In an alternative implementation, the method may further include: the SF network element determines (or discovers) that the sensing scenario corresponding to the sensing service has changed. Or, the method may further include: the SF network element obtains information for indicating the change of the sensing scenario. Thus, the SF network element can learn that the sensing scenario corresponding to the sensing service has changed. The embodiments of the present application do not limit the manner in which the SF network element learns that the sensing scenario has changed.

[0236] In an alternative implementation, that the sensing scenario corresponding to the sensing service changes includes: the sensing scenario corresponding to the sensing service changes from a first sensing scenario to a second sensing scenario. The SF network element determines, based on the network statistical information, the transmission resources that need to be adjusted for the sensing service, including: the SF network element determines whether the transmission resources corresponding to the first sensing scenario are the same as those corresponding to the second sensing scenario; if not, the SF network element determines the transmission resources that need to be adjusted for the sensing service.

[0237] For example, if the sensing scenario corresponding to the sensing service changes from a sunny day scenario to a rainy day scenario, and the transmission resources corresponding to the rainy day scenario are more than those corresponding to the sunny day scenario, then the SF network element can determine that it is necessary to increase the transmission resources allocated to the sensing service.

[0238] Another example is that if the sensing scenario corresponding to the sensing service changes from a road unobstructed scenario to a road congested scenario, and the transmission resources corresponding to the road congested scenario are more than those corresponding to the road unobstructed scenario change, then the SF network element can determine that it is necessary to increase the transmission resources allocated to the sensing service.

[0239] For another example, if the perception scenario corresponding to the perception service changes from the lunchtime scenario to the evening rush hour scenario, and the transmission resources corresponding to the evening rush hour scenario are more than those corresponding to the lunchtime scenario, then the SF network element can determine that it is necessary to increase the transmission resources allocated to the perception service.

[0240] In an alternative implementation, performing perception based on the transmission resources corresponding to the perception scenario in the network statistics can meet the requirements for the perception service in that perception scenario. For example, when the perception scenario corresponding to the perception service is Perception Scenario #1, allocate the transmission resources corresponding to Perception Scenario #1 to the perception service, and thus perform perception based on the transmission resources corresponding to Perception Scenario #1, which can meet the requirements for the perception service. When the perception scenario corresponding to the perception service is Perception Scenario #2, allocate the transmission resources corresponding to Perception Scenario #2 to the perception service, and thus perform perception based on the transmission resources corresponding to Perception Scenario #2, which can meet the requirements for the perception service.

[0241] In an alternative implementation, N perception scenarios in the network statistics correspond to the perception service. Exemplarily, the network statistics may include N perception scenarios corresponding to each perception service among one or more perception services, and the transmission resources corresponding to each perception scenario, where the perception scenarios corresponding to different perception services may be partially the same, completely the same, or completely different, and the number of perception scenarios corresponding to different perception services may be the same or different, without limitation. Then, the SF network element can determine the perception service whose perception scenario has changed from one or more perception services, and thus determine whether it is necessary to adjust the transmission resources allocated to the perception service based on the transmission resources corresponding to the N perception scenarios respectively corresponding to the perception service.

[0242] For example, the network statistics are shown in Table 2.

[0243] Table 2

[0244]

[0245] Based on Table 2, for example, in Perception Scenario #1, the transmission resources allocated to Perception Service #1 are Transmission Resources #1. Thereafter, the SF network element detects that the perception scenario corresponding to Perception Service #1 changes from Perception Scenario #1 to Perception Scenario #2, and the SF network element can determine from the network statistics that for Perception Service #1, the transmission resources corresponding to Perception Scenario #2 are Transmission Resources #2. If Transmission Resources #2 are more than Transmission Resources #1, the SF network element determines that it is necessary to increase the transmission resources allocated to Perception Service #1. If Transmission Resources #2 are less than Transmission Resources #1, the SF network element determines that it is necessary to reduce the transmission resources allocated to Perception Service #1. If Transmission Resources #2 are the same as Transmission Resources #1, the SF network element determines that it is not necessary to adjust the transmission resources allocated to Perception Service #1.

[0246] In an alternative embodiment, the network statistical information further includes sensing requirements corresponding to N sensing scenarios respectively. Sensing based on the transmission resources corresponding to the sensing scenarios in the network statistical information can meet the sensing requirements corresponding to the sensing scenarios. For example, if the requirement for sensing service #1 is the first requirement, then, the SF network element can determine the sensing scenario corresponding to the first requirement based on the network statistical information, and determine whether to adjust the transmission resources allocated to sensing service #1 based on the transmission resources corresponding to the sensing scenario corresponding to the first requirement, so as to meet the requirement for sensing service #1.

[0247] For example, the network statistical information is shown in Table 3 as follows.

[0248] Table 3

[0249]

[0250] Based on Table 3, for example, the requirement for the sensing service is requirement #2. In the case of requirement #2, in sensing scenario #1, the transmission resources allocated to sensing service #1 are transmission resources #3. Thereafter, the SF network element detects that the sensing scenario corresponding to sensing service #1 changes from sensing scenario #1 to sensing scenario #2. The SF network element can determine from the network statistical information that in the case of requirement #2, for sensing service #1, the transmission resources corresponding to sensing scenario #2 are transmission resources #4. If transmission resources #4 are more than transmission resources #3, the SF network element determines that it is necessary to increase the transmission resources allocated to sensing service #1. If transmission resources #4 are less than transmission resources #3, the SF network element determines that it is necessary to reduce the transmission resources allocated to sensing service #1. If transmission resources #4 are the same as transmission resources #3, the SF network element determines that it is not necessary to adjust the transmission resources allocated to sensing service #1.

[0251] In an alternative embodiment, when the sensing scenario corresponding to the sensing service changes, the SF network element can determine whether to adjust the transmission resources allocated to the sensing service; if it is necessary to adjust the transmission resources allocated to the sensing service, step S302 is executed.

[0252] S302. The SF network element sends the ninth piece of information to the sensing device, and the ninth piece of information is used to request to adjust the transmission resources allocated to the sensing service.

[0253] Optionally, the ninth piece of information includes a policy for adjusting the transmission resources allocated to the sensing service. For example, based on Table 2, the SF network element detects that the sensing scenario corresponding to sensing service #1 changes from sensing scenario #1 to sensing scenario #2, and transmission resources #2 are more than transmission resources #1. The ninth piece of information may include the quantity of transmission resources that need to be increased for the transmission resources allocated to sensing service #1, and the quantity of transmission resources that need to be increased is: the quantity of transmission resources that the difference between transmission resources #2 and transmission resources #1.

[0254] S303. The sensing device adjusts the transmission resources allocated for the sensing service based on the ninth piece of information.

[0255] In another alternative implementation, in the information transmission method 300, the AF network element determines the transmission resources that need to be adjusted for the sensing service based on the network statistical information. Exemplarily, as Figure 9 shown, Figure 9 the information transmission method 300 shown includes steps S401 to S404. Figure 9 The information transmission method 300 shown is similar to Figure 8 the information transmission method 300 shown. For specific elaboration, reference can be made to the relevant elaboration of the information transmission method 300 shown in Figure 8 and details will not be repeated here.

[0256] S401. When the sensing scenario corresponding to the sensing service changes, the AF network element determines the transmission resources that need to be adjusted for the sensing service based on the network statistical information. The network statistical information includes N sensing scenarios and the transmission resources respectively corresponding to the N sensing scenarios, where N is an integer greater than 1.

[0257] In an alternative manner, when the sensing scenario corresponding to the sensing service changes, the AF network element may determine whether the transmission resources allocated for the sensing service need to be adjusted; if the transmission resources allocated for the sensing service need to be adjusted, step S402 is executed.

[0258] S402. The AF network element sends the tenth piece of information to the SF network element, and the tenth piece of information is used to request the adjustment of the transmission resources allocated for the sensing service. Correspondingly, the SF network element receives the tenth piece of information from the AF network element.

[0259] S403. The SF network element sends the eleventh piece of information to the sensing device, and the eleventh piece of information is used to request the adjustment of the transmission resources allocated for the sensing service. Correspondingly, the sensing device receives the eleventh piece of information from the SF network element. The eleventh piece of information may be the same as the tenth piece of information, or the eleventh piece of information may also be information generated by the SF network element based on the tenth piece of information.

[0260] S404. The sensing device adjusts the transmission resources allocated for the sensing service based on the eleventh piece of information.

[0261] In summary, the information transmission method 300 can, in a scenario where the perception scenario corresponding to the perception service changes, determine the transmission resources that need to be adjusted for the perception service based on network statistical information, and send information for requesting adjustment of the transmission resources allocated to the perception service, which is beneficial to adjusting the transmission resources allocated to the perception service, thus facilitating the matching of the adjusted transmission resources with the changed perception scenario, further facilitating the satisfaction of the requirements for the perception service, and further improving the perception performance.
