Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information transmission method and device. Background Art

[0003] With the widespread adoption of communications technology, communication equipment has gradually expanded from hotspots to the entire region. Simultaneously, the development of communications technology has also provided the conditions for addressing new scenarios and demands. Perception is a technology that can be further enabled after communications technology has reached a certain stage of development. Perception technology collects perception signals after they are reflected by objects and further processes them to achieve perception of objects and environments. Perception and communication technologies can be combined in a process known as communication-perception integration. In this scenario, communications devices can transmit perception signals, which are then used for perception.

[0004] Application function (AF) network elements can initiate requests to the network to establish sensing services, so that the network can control sensing devices to perform sensing. AF network elements may also have certain requirements for sensing services. How to meet these requirements for sensing services is a technical issue that needs to be solved.

The SF network element sends second information to the sensing device, and the second information is used to adjust the transmission resources allocated to the sensing service.

[0007] It can be seen that after obtaining the perception data, this method can determine the transmission resources that need to be adjusted to be allocated to the perception service based on the first information determined based on the perception data and the demand for the perception service, and send the second information to the perception device, which is conducive to the perception device adjusting the transmission resources allocated to the perception service, so that the perception device perceives based on the adjusted transmission resources, which is conducive to meeting the demand for the perception service and thus improving the perception performance.

[0009] In an optional implementation, the second information includes one or more of the following: a performance parameter that does not meet the requirements, or a gap between the performance parameter that does not meet the requirements and the requirements.

[0013] In an optional implementation, the method further includes: the SF network element receiving third information from the sensing device, where the third information is used to indicate whether the transmission resources allocated to the sensing service are successfully adjusted.

[0014] In an optional embodiment, the method further includes: the SF network element sending the perception data obtained using the adjusted transmission resources to the AF network element. The SF network element receives fourth information or fifth information from the AF network element, where the fourth information indicates that the demand for the perception service is met, and the fifth information requests a reduction in the transmission resources allocated for the perception service. The SF network element sends sixth information to the perception device, where the sixth information requests a reduction in the transmission resources allocated for the perception service.

[0015] In an optional embodiment, the method further includes: the SF network element determining, based on the sensing data obtained through the adjusted transmission resources, that the demand for the sensing service is met, and the SF network element sending sixth information to the sensing device, the sixth information being used to request a reduction in the transmission resources allocated for the sensing service.

[0016] On the second aspect, the present application provides an information transmission method, which can be applied to AF network elements, chips in AF network elements, and logic modules or software that can realize all or part of the functions of AF network elements. The following description is taken as an example of AF network elements. The method includes: the AF network element determines the transmission resources that need to be adjusted to be allocated to the perception service based on the first information and the demand 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 AF network element sends the seventh information to the SF network element, and the seventh information is used to request adjustment of the transmission resources allocated to the perception service.

[0017] It can be seen that after obtaining the perception data, this method can determine the transmission resources that need to be adjusted to be allocated for the perception service based on the first information determined based on the perception data and the demand for the perception service, and send the seventh information to the SF network element, which is conducive to adjusting the transmission resources allocated for the perception service, so as to perform perception based on the adjusted transmission resources, which is conducive to meeting the demand for the perception service and thus improving the perception performance.

[0018] In an optional implementation, the seventh information is specifically used to request adjustment of the transmission resources allocated to the perception service with respect to the first performance parameter, where the first performance parameter is a performance parameter that does not meet the requirements.

[0019] In an optional implementation manner, the seventh information includes one or more of the following: a performance parameter that does not meet the requirements, or a gap between the performance parameter that does not meet the requirements and the requirements.

[0021] In an optional embodiment, the method further includes: the AF network element receiving, from the SF network element, sensing data obtained using the adjusted transmission resources. The AF network element determines, based on the sensing data obtained using the adjusted transmission resources, that the demand for the sensing service is met. The AF network element sends, to the SF network element, fourth information or fifth information, where the fourth information indicates that the demand for the sensing service is met, and the fifth information requests a reduction in the transmission resources allocated for the sensing service.

The SF network element sends ninth information to the perception device, where the ninth information is used to request adjustment of the transmission resources allocated to the perception service.

[0023] It can be seen that this method can determine the transmission resources that need to be adjusted for the perception service based on network statistical information when the perception scenario corresponding to the perception service changes, and send the ninth information to the perception device, which is conducive to adjusting the transmission resources allocated for the perception service, thereby facilitating the matching of the adjusted transmission resources with the changed perception scenario, and further facilitating meeting the demand for perception services, thereby improving perception performance.

The AF network element sends a tenth message to the SF network element, and the tenth message is used to request adjustment of the transmission resources allocated to the perception service.

[0056] For the sending and receiving operations involved in the processor, unless otherwise specified, or unless they conflict with their actual functions or internal logic in the relevant descriptions, they can be more generally understood as processor output, reception, input and other operations, rather than sending and receiving operations directly performed by the RF circuit and antenna.

[0057] During implementation, the processor may be a processor specifically configured to execute these methods, or may be a processor that executes computer instructions in a memory to execute these methods, such as a general-purpose processor. The memory may be a non-transitory memory, such as a read-only memory (ROM), which may be integrated with the processor on the same chip or disposed on separate chips.

[0081] Second, in this application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. In the textual description of this application, the character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one 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. Wherein a, b and c can be single or multiple, respectively.

[0082] Third, throughout this application, the terms "first," "second," and various numerical references are used for descriptive purposes only and are not intended to limit the scope of the embodiments of this application. For example, they are used to distinguish between different messages, rather than to describe a specific order or precedence. It should be understood that these references are interchangeable, where appropriate, to allow for the description of scenarios beyond the embodiments of this application.

[0083] Fourth, in this application, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusions.

"Receiving information from XX (device / network element) or receiving information from XX (device / network element)" can be understood as the source of the information being the device, which can include receiving information from the device directly or indirectly. The information may undergo necessary processing between the source and destination, such as format changes, but the destination can understand the valid information from the source.

[0086] The network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application.

[0092] Access network equipment in the (R)AN includes, but is not limited to, base stations (BS), radio network controllers (RNC), base station controllers (BSC), base transceiver stations (BTS), home network equipment (e.g., home evolved Node B, or HNB), baseband units (BBU), wireless relay nodes, wireless backhaul nodes, and transmission and reception points (TRP; or, transmission points, TP). A base station is a device deployed in a radio access network that provides wireless communication capabilities. It can also be referred to as a base station device, such as an evolved Node B (eNB or e-NodeB) or Node B in an LTE system, a base station (gNodeB or gNB) in a 5G system, or a base station in a 6G system. A base station can include a BBU and a remote radio unit (RRU). The BBU and RRU can be placed in different locations, for example, the RRU can be remotely located in an area with high traffic volume, while the BBU can be placed in a central computer room. The BBU and RRU can also be placed in the same machine room. The BBU and RRU can also be different components under one rack. The base station can be in the following forms: macro base station, micro base station (also known as small station), micro-micro base station, relay station, access point, balloon station, etc. Optionally, in some deployments of access network equipment, the access network equipment may include a centralized unit (CU) and a distributed unit (DU), etc. In other deployments of access network equipment, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In some other deployments of access network equipment, the access network equipment can also be an open radio access network (ORAN) architecture, etc. This application does not limit the specific deployment method of the access network equipment.

[0093] The AMF network element is responsible for the mobility management of terminal devices, including mobile state management, allocation of temporary identity identifiers for terminal devices, and authentication and authorization of terminal devices.

[0094] The SMF network element is responsible for user plane network element selection, user plane network element reselection, Internet Protocol (IP) address allocation, bearer establishment, modification and release, and 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. Its specific functions include: configuring the data forwarding details of the PDU session (such as forwarding rules, QoS guarantee rules, etc.), event reporting, network element-level configuration information exchange, etc.

[0095] The UDM network element is responsible for managing contract data and notifying the corresponding network element when the contract data is modified.

[0096] The UDR network element is used to store and retrieve contract data, policy data, and public architecture data. It is also used by UDM network elements, PCF network elements, and NEF network elements to obtain relevant data. The UDR network element must have different data access authentication mechanisms for different types of data, such as contract data and policy data, to ensure data access security. The UDR network element must be able to return a failure response with an appropriate reason value for illegal service-based operations or data access requests.

[0097] AF network elements are used to provide certain application layer services to terminal devices. When providing services to terminal devices, AF network elements have requirements for QoS policies and charging policies, and need to notify the network. At the same time, AF network elements also need application-related information fed back by the core network.

[0098] The UPF network element supports all or part of the following functions: interconnecting PDU sessions with the data network, packet routing and forwarding, and data packet inspection. Among them, the UPF network element supports packet routing and forwarding, for example: the UPF network element supports uplink classifier (UL CL) and forwarding traffic to the data network, and supports branching points to support multi-homed PDU sessions.

[0099] Please refer to Figure 3, which is a schematic diagram of a communication system provided in an embodiment of the present 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 perception. The sensing device can send a sensing signal and receive a signal reflected by the sensing signal. The sensing signal is a signal used for perception. The sensing device can be, for example, a terminal device or an access network device. The embodiment of the present application is not limited to the name "sensing device" and other names can also be used. For example, "sensing device" can also be replaced by "sensing entity". For the sake of convenience, the following text will use "sensing device" as an example for explanation.

[0100] SF supports some or all of the following functions: session management function for perceptual data transmission (for example, determining the QoS of transmitted perceptual data, etc.), managing the accuracy parameters of perception (for example, obtaining the corresponding perceptual accuracy that can be processed by the network side according to the requirements of the AF network element), and processing of perceptual data (for example, converting perceptual measurement data into the final target result information of perception).

[0101] 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, and this application does not specifically limit 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 need to interact with other core network elements through the NEF network element.

[0102] In one possible implementation, the SF network element can have a separate control plane and user plane. That is, the SF control plane (SF-C) functions and the SF user plane (SF-U) functions are separated. The SF-C can send control commands to the access network device via the control plane; the SF-U can receive perception data from the access network device via the data plane and optionally process the perception data to obtain perception results.

[0103] 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 the location management function (LMF) network element. Alternatively, SF can also be combined with other functions. This application does not limit the naming of the network element obtained by the combination. For example, SF can be combined with SMF and / or UPF, and the combined network element is named SF network element or other names. Based on actual needs, SF can also be other possible situations without limitation. For the sake of convenience, the SF network element will be used as an example in the following text. The SF network element is an independent network element, or the SF network element is a network element obtained by combining SF with other functions. The case 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 those performed by the network element to which SF belongs, and will not be repeated.

[0104] It can be understood that the embodiments of the present application are described using the 5G system as an example. When the solutions of the embodiments of the present application are applied to 6G or other communication systems, the corresponding network element names, network element deployment methods, and interfaces may change, and this application does not limit this.

[0105] The following describes the relevant concepts involved in the embodiments of this application.

[0106] 1. Establish a process for business awareness

[0107] After receiving the first request message, the SF network element may establish the perception service. The first request message is used to request the establishment of the perception service. The first request message may include one or more of the following: perception target area information, perception service requirement information, address information of the AF network element, and the start time of the perception service. The perception service requirement information may include one or more of the following: information related to perception service quality, information related to perception data transmission control, or information related to perception data.

[0108] The information related to the quality of the sensing service includes the type of sensing service and / or the requirements for the sensing service. Examples of sensing service types include Internet of Vehicles services and drone intrusion detection services. Requirements for sensing services include, for example, requirements for positioning accuracy, speed measurement accuracy, sensing resolution, and latency.

[0109] The relevant information related to the control of the perception data transmission is used to indicate the demand for the frequency of transmitting the perception data. For example, the frequency of transmitting the perception data is a single transmission of the perception data, or a periodic transmission of the perception data, or a triggered transmission of the perception data. Among them, the triggered transmission of the perception data can be understood as: transmitting the perception data when the trigger condition is met. For example, the trigger condition for the perception device to transmit the perception data is: obtaining information for requesting the transmission of the perception data, that is, the perception device transmits the perception data when / after obtaining the information for requesting the transmission of the perception data. In addition, in the embodiment of the present application, the transmission of the perception data can be uplink transmission of the perception data, and the uplink transmission of the perception data can also be understood as reporting of the perception data. For example, the perception device is an access network device, and the access network device transmits the perception data, which can be: the access network device sends the perception data to the UPF network element or the SF network element. The UPF network element can be, for example, a sensing UPF network element (i.e., a Sensing-UPF network element), and the SF network element can be, for example, a user plane function (e.g., SF-U) of the SF network element. It will not be described in detail below.

[0110] Perception data related information is used to indicate the demand for the type of perception data to be transmitted. Exemplarily, the required perception data type is point cloud information, which is a set of points on the reflective surface of the object where the perception signal is reflected by the perception signal, wherein the perception signal is a signal used for perception. Exemplarily, the required perception data type is the perception result, which can also be understood as the final measurement result. The final measurement result can be, for example, descriptive information of the measured object. For example, the description information of the event is used to describe whether there is an intruder for a given perception area. For another example, the description information of the event is used to describe a drawn three-dimensional (3D) map. For another example, the description information of the event is used to describe the perception target perceived within a given perception area (for example, the perception target is a vehicle, and the description information of the event is used to describe the vehicle perceived within a given perception area).

[0111] In addition, the perceived service requirement information may include not only the content already mentioned, but also other requirements for the perceived service, without limitation.

[0112] In addition, the embodiment of the present application does 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. 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, an NEF network element). It is worth noting that what the intermediate network element sends to the SF network element may be the first request message itself received by the intermediate network element from the AF network element, or it may be information generated by the intermediate network element based on 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 first request message may be provided to the SF network element by the operation and maintenance system (OAM).

[0113] In addition, in the embodiment of the present application, "AF network element" can also be replaced by: "application server", "third-party application", "data collector" or "application requester", etc. For the sake of convenience, the embodiment of the present application takes "AF network element" as an example for explanation, and will not be repeated later.

[0114] The following takes the example of sending a first request message from the AF network element to the SF network element, and takes the two scenarios of the perception device being an access network device and the perception device being a terminal device as examples to exemplify the process of establishing a perception service, as described in the following optional method a and method b.

[0115] Method a: The sensing device is an access network device

[0116] With reference to Figure 4 , the process for establishing a perception service includes: the AF network element sends a first request message to the SF network element; in response, 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, the first response message including identification information of the perception service; in response, 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 perception data. Based on the perception service requirement information, the SF network element determines perception accuracy requirement information. The SF network element sends a second request message to the access network device, the second request message including the perception accuracy requirement information and relevant parameters for transmitting perception data; in response, the access network device receives the second request message from the SF network element. Based on the second request message, the access network device determines the transmission resources to be allocated for the perception service. The access network device sends a second response message to the SF network element. The second response message is a response message to the second request message and may, for example, include information #1 indicating the transmission resources allocated for the perception service.

[0117] After the perception service is established, the access network device can collect perception data based on the transmission resources allocated for the perception service and send the perception data directly or through the UPF network element to the SF network element, which then sends the perception data to the AF network element. In addition, it is worth noting that the SF network element can send ( / report) the perception data collected by the SF network element to the AF network element, or it can also be data processed by the SF network element, without limitation.

[0118] In an embodiment of the present application, the identification information of the perception service may be, for example, a perception identification (ID) (i.e., a sensing ID), and the sensing ID may represent a specific (internal operator) perception service. Exemplarily, the numbering rule of the sensing ID is a combination of the operator identification and the perception service identification, where the "perception service identification" may also be understood as the "perception service identification." For example, the sensing ID may be expressed as: [operator identification] [perception service identification], where each field may be represented by a binary, octal, decimal, or hexadecimal number.

[0119] In one possible implementation method, the operator pre-configures the range of perception service identifiers that can be assigned by the SF network element; after the SF network element obtains the first request message, the SF network element assigns a perception service identifier that has not yet been assigned as the identification information of the perception service. For example, taking the use of binary numbers to represent the perception service identifier as an example, the operator pre-configures the range of perception service identifiers that can be assigned by SF network element #1 as: 000 to 111 (binary). Among 000 to 111, the perception service identifiers that have not yet been assigned are 100 to 111. Then, after SF network element #1 obtains the first request message, SF network element #1 can select a perception service identifier from 100 to 111 as the identification information of perception service #1. For example, SF network element #1 selects "101" from 100 to 111 as the identification information of perception service #1.

[0120] In an embodiment of the present application, relevant parameters for transmitting perception data may include, for example, QoS description information (QoS profile) for transmitting perception data and tunnel information for transmitting perception data. The QoS profile may include one or more of the following: a QoS identifier (QoS identifier), an allocation and retention priority (ARP), a guaranteed bit rate (GBR), or a maximum bit rate (MBR). 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 perception data, without limitation.

[0121] In an embodiment of the present application, in one possible implementation method, the perception accuracy requirement information includes one or more levels of perception accuracy requirements. This embodiment can be applied to a scenario where the perception service requirement information in the first request message includes one or more perception service quality-related information. In this scenario, it is understandable that one perception service can correspond to one or more perception service quality-related information, and different perception service quality-related information is not exactly the same. For example, the perception accuracy requirement information includes two levels of perception accuracy requirements, as shown in Table 1 below.

[0122] Table 1

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

[0124] For level 2, the perception accuracy requirements for positioning estimation accuracy are: ≤ 5m. The perception resolution requirement is: < 5m. The maximum latency requirement for perception services is: < 1000ms. The refresh rate requirement is: < 1s. The missed detection rate requirement is: ≤ 5%. The false detection rate requirement is: ≤ 2%.

[0125] Optionally, when the sensing accuracy requirement information includes multiple levels of sensing accuracy requirements, the access network device can adjust the sensing accuracy requirements to be used. For example, referring to Table 1, the access network device allocates transmission resource #1 to the sensing service based on the sensing accuracy requirement of level 1. Subsequently, the access network device discovers that transmission resource #1 cannot meet the sensing accuracy requirement of level 1 and adjusts the sensing accuracy requirement to level 2. However, the access network device may not change the transmission resource allocated to the sensing service; that is, the transmission resource allocated to the sensing service remains transmission resource #1.

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

[0127] In conjunction with Figure 5, the process of establishing a perception service includes: the AF network element sends a first request message to the SF network element; accordingly, 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 identification information of the perception service; accordingly, 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 perceived terminal device. The AF network element or the SF network element sends to the perceived terminal device: identification information of the perception service, and accuracy requirement information of the perception service. In addition, the network also establishes a channel for transmitting perception data, which is used for the terminal device to send perception data to the AF network element through the UPF network element and the SF network element.

[0128] Among them, the AF network element or SF network element determines the perceived terminal device, for example, it can be: the AF network element or SF network element can determine the perceived terminal device based on the target area information perceived in the first request message. In addition, for the specific explanation of the identification information of the perception service, please refer to the relevant explanation in method a. The accuracy requirement information of the perception service can include, for example: positioning accuracy information, speed measurement accuracy information, perception resolution, delay, etc. The accuracy requirement information of the perception service can also refer to the relevant explanation of the perception accuracy requirement information in method a, which will not be repeated. In addition, the AF network element or SF network element can send information to the perceived terminal device directly to the terminal device, or it can also be sent to the terminal device through an intermediate network element (for example, an access network device where the terminal device resides), without limitation.

[0129] After the perception service is established, the terminal device can collect perception data and send the perception data to the UPF network element. The UPF network element sends the perception data to the SF network element, and the SF network element then sends the perception data to the AF network element. In addition, it is worth noting that the SF network element can send ( / report) the perception data collected by the SF network element to the AF network element, or it can be the data processed by the SF network element on the collected perception data, without limitation. The SF network element can report the perception data through the user plane (such as SF-U) or through the control plane (such as SF-C), without limitation.

[0130] In addition, the information transmission method described in the embodiment of the present application can be applied to the scenario where the perception service is established. The above-mentioned methods a and b are only exemplary explanations of the process of establishing the perception service. In the scenario where the perception service is established and the information transmission method described in the embodiment of the present application is applied, the specific process of establishing the perception service is not limited.

[0131] It is worth noting that the word "determine" mentioned in the embodiments of the present application can specifically refer to the specific action of "determining", and can also be replaced by "discovery", without limitation.

[0132] The following is a detailed description of the embodiments of the present application in conjunction with the accompanying drawings. The embodiments of the present application use SF network elements, AF network elements, and sensing devices as examples to illustrate the corresponding methods, but the present application does not limit the execution subjects of the methods. For example, the network element / device in the method may also be a chip, chip system, or processor that supports the network element / device to implement the corresponding method, or a logical module or software that can implement all or part of the functions of the network element / device.

[0133] Please refer to FIG. 6 , which is a flow chart of an information transmission method 100 provided in an embodiment of the present application. The information transmission method 100 includes the following steps.

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

[0135] The first information includes one or more of the following: error event information, error event ratio, or performance parameters that do not meet requirements, and the first information is determined based on 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 correspond to multiple perception services. The perception data may be obtained by the perception device through perception collection for the perception service, or the perception data may be obtained by the perception device through perception collection based on its own capabilities and then used for the perception service, without limitation.

[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. Furthermore, in cases where the perception data is not a perception result (for example, the perception data is point cloud information), the perception result may be determined based on the perception data. For a detailed description of point cloud information and perception results, please refer to the aforementioned related descriptions and will not be repeated here.

[0138] In an optional embodiment, the error event information includes the error event. Optionally, the error event information also includes time information corresponding to the error event. The time information corresponding to the error event can be represented, for example, by a specific moment, or can also be represented by a time identifier. The time identifier in the time information corresponding to the error event can be, for example, the sequence number of the time window to which the error event belongs, or can also be the sequence number of the time series to which the error event belongs. This embodiment of the application does not limit the representation method of the time information.

[0139] Optionally, the error event includes one or more of the following: a missed detection event, a false detection event, or an inaccurate perception accuracy event. Exemplarily, a missed detection event may be manifested as: the perception target is not perceived. For example, the perception target is a vehicle, and the actual vehicle #1 is not perceived, which means that vehicle #1 is missed. Exemplarily, a false detection event may be manifested as: a non-perception target is perceived as the perception target. For example, the perception target is a motor vehicle, and vehicle #1 is perceived, but vehicle #1 is actually a non-motor vehicle, which means that vehicle #1 is falsely detected. Exemplarily, a false detection event may also be manifested as: the perception target is perceived in a scenario where the perception target does not exist. For example, the perception target is a vehicle, and there are actually only vehicle #1 and vehicle #2, but vehicles #1, #2, and #3 are perceived, which means that vehicle #3 is falsely detected. False detection events may also be referred to as wrong detection events. In addition, in addition to the events already mentioned, error events may also include other types of events, which are not limited to these.

[0140] The following is an exemplary explanation of error events, as described in the following optional implementations 1.1 to 1.4.

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

[0142] For example, assuming the perception target is a vehicle and the perception area is area #1, based on the perception data, it is determined that at time #1, vehicles #1 and #2 are perceived within area #1. The camera image shows that at time #1, vehicles #1, #2, and #3 are within area #1. Therefore, failure to perceive vehicle #3 within area #1 at time #1 is a missed detection event.

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

[0144] For example, assuming the perception target is a vehicle and the perception area is area #1, based on the perception data, it is determined that: at time #1, vehicles #1, #2, #3, #4, and #5 are perceived within area #1; at time #2, vehicles #1, #2, #3, and #5 are perceived within area #1; and at time #3, vehicles #1, #2, #3, #4, and #5 are perceived within area #1. Therefore, vehicle #4 is perceived at both time #1 and time #3, but not at time #2. Therefore, the failure to perceive vehicle #4 at time #2 can be determined to be a missed detection event, and the time information corresponding to this missed detection event is, for example, time #2.

[0145] For another example, let's assume the perception target is a vehicle and the perception area is area #1. Based on the perception data, it can be determined that at time #1, time #2, time #4, time #5, and time #6, only vehicles #1, #2, #3, and #4 are perceived. At time #3, in addition to vehicles #1, #2, #3, and #4, vehicle #5 is also perceived. Therefore, vehicle #5 is not perceived at time #1, #2, #4, #5, or #6, but is perceived at time #3. Therefore, the perception of vehicle #5 at time #3 can be determined to be a false detection event, and the time information corresponding to this false detection event is, for example, time #3.

[0146] In embodiment 1.3, an error event is determined by comparing the perception data (or a perception result obtained based on the perception data) with historical information, where the historical information may be, for example, previously recorded perception data or perception results.

[0147] For example, based on historical information, it is determined that vehicle #1 was present in area #1 at 9:00 AM and 10:00 AM every day from day 1 to day 15. Based on sensing data, it is determined that vehicle #1 was not sensed in area #1 at 9:00 AM on day 16, but was sensed in area #1 at 10:00 AM on day 16. Therefore, the failure to sense vehicle #1 in area #1 at 9:00 AM on day 16 can be considered a missed detection event.

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

[0149] For example, based on perception data, it is determined that a car accident was not detected on road section #1 at time #1. Based on user feedback, it is determined that a car accident occurred on road section #1 at time #1. Therefore, the failure to detect a car accident on road section #1 at time #1 can be considered a missed detection event.

[0150] For example, based on perception data, it is determined that a car accident occurred in the left lane of road section #1 at time #1. Based on user feedback, it is determined that a car accident occurred in the right lane of road section #1 at time #1. Therefore, the car accident detected in the left lane of road section #1 at time #1 can be considered a false detection.

[0151] In addition, the error event may be determined based on one or more implementations in the above-mentioned implementations 1.1 to 1.4, or may be determined based on other methods, or may be determined by combining one or more implementations in the above-mentioned implementations 1.1 to 1.4 with other methods. The method for determining the error event in the embodiments of the present application is not limited.

[0152] In an optional embodiment, the error event ratio is the ratio of error events. It is understandable that the error event ratio can be determined based on the error events. Exemplarily, the error event ratio can be: the ratio of error events in several 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 based on other methods) time window. Optionally, the error event ratio includes one or more of the following: the missed detection event ratio, the false detection event ratio, or the perception accuracy inaccurate event ratio, wherein the missed detection event ratio can also be understood as the missed detection rate, and the false detection event ratio can also be understood as the false detection rate. In addition, in addition to the content already mentioned, the error event ratio can also include other types of event ratios, which are not limited to this.

[0153] For example, if measurement window #1 includes 20 time series, and two of these 20 time series have missed detection events, then the missed detection event ratio is 10%. If three of these 20 time series have false detection events, then the false detection event ratio is 15%.

[0154] In an optional embodiment, the performance parameter that does not meet the requirements is a performance parameter that does not meet the requirements for the sensing service. The performance parameter that does not meet the requirements may be one or more. Exemplarily, the performance parameter may be the accuracy of positioning estimate by sensing, sensing resolution, maximum sensing service latency, refresh rate, missed detection rate, or false detection rate, etc. In addition, in addition to the performance parameters mentioned above, other performance parameters may also be used. The embodiments of the present application do not limit the types of performance parameters.

[0155] Optionally, the performance parameters that do not meet the requirements can be determined based on the requirements for the perception service, as well as the error event information or the error event ratio. For example, for the perception 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 example, measurement window #1 includes 20 time series, and missed detection events occurred in 2 of these 20 time series. It can be seen that the missed detection event ratio is 10%, and the missed detection rate does not meet the requirements. Then, the performance parameters that do not meet the requirements include the missed detection rate. For another example, measurement window #2 includes 40 time series, and missed detection events occurred in 1 of these 40 time series. It can be seen that the missed detection event ratio is 2.5%, and the missed detection rate meets the requirements. Then, the performance parameters that do not meet the requirements do not include the missed detection rate.

[0156] In addition, in embodiments of the present application, the first information may include, in addition to the aforementioned content, other information determined based on the perception data; illustratively, it may also include other information obtained by analyzing or processing the perception data, such as the specific value of a performance parameter that does not meet the requirements. This is not limited to this.

[0157] The following is an exemplary explanation of the method for obtaining the first information, as described in the following optional implementation 2.1 and implementation 2.2.

[0158] In implementation mode 2.1, the method further includes: the AF network element sending the first information to the SF network element; and correspondingly, the SF network element receiving the first information from the AF network element.

[0159] Exemplarily, after the SF network element receives the perception data from the perception device, it sends the perception data to the AF network element. The AF network element determines whether the perception result is erroneous based on the perception data. If the AF network element determines that the perception result is erroneous, the AF network element sends a first message to the SF network element. Whether the perception result is erroneous can also be understood as whether the perception result is accurate. Optionally, the AF network element determines whether the perception result is erroneous based on the perception data, including: the AF network element determines whether there is an error event based on the perception data; if there is an error event, the perception result is erroneous. It is understandable that if the AF network element determines that there is an error event based on the perception data, it can be considered that the perception data is inaccurate, and thus the perception result is considered erroneous. In addition, for the specific description of the method for determining the error event and the method for determining the first information, please refer to the aforementioned related description and will not be repeated here.

[0160] In addition, the embodiments of the present application do not limit the frequency at which the AF network element transmits the first information to the SF network element. For example, the AF network element may periodically transmit the first information to the SF network element, aperiodically transmit the first information to the SF network element, or transmit the first information to the SF network element when a trigger condition is met. The following provides an exemplary explanation.

[0161] For example, the AF network element sends first information to the SF network element at a period of t0. The AF network element determines first information #1 based on the sensing data acquired between t and t+t0, and sends the first information #1 to the SF network element at time t+t0 (or around time t+t0). The AF network element determines first information #2 based on the sensing data acquired between t+t0 and t+2t0, and sends the first information #2 to the SF network element at time t+2t0 (or around time t+2t0). The AF network element determines first information #2 based on the sensing data acquired between t+2t0 and t+3t0, and sends the first information #3 to the SF network element at time t+3t0 (or around time t+3t0), and so on.

[0162] For another example, the AF network element sends first information including M error events to the SF network element every time it determines M error events, where M is a positive integer. For example, if M is 1, the AF network element determines error event #1 and sends first information #1 to the SF network element, where first information #1 includes error event #1. Thereafter, the AF network element determines error event #2 and sends first information #2 to the SF network element, where first information #2 includes error event #2.

[0163] Optionally, the method further includes: the AF network element sends identification information of the perception service to the SF network element; correspondingly, the SF network element receives the identification information of the perception service from the AF network element. This method enables the SF network element to know the perception service corresponding to the first information. Exemplarily, if the AF network element determines that the perception result is erroneous based on the perception data corresponding to the perception service, the AF network element sends the first information and the identification information of the perception service to the SF network element. Optionally, the identification information of the perception service can be determined by the SF network element during the process of establishing the perception service. For the identification information of the perception service and the process of establishing the perception service, please refer to the aforementioned relevant explanations and will not be repeated here.

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

[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 perception service, or the seventh information, for example, can be carried in the perception service notification message sent by the AF network element to the SF network element. The perception service notification message can be, for example, a perception service update request (Nsf_SensingSession_Update Request) message.

[0166] In addition, in an embodiment of the present application, the AF network element sends information (for example, the first information, identification information of the perception service, the seventh information, etc.) to the SF network element, which may be sent directly by the AF network element to the SF network element. This method can be applied to the case where the AF network element is located in the trust domain of the network. Alternatively, the AF network element sends information (for example, the first information, identification information of the perception service, the seventh information, etc.) to the SF network element, which may also be sent by the AF network element to the SF network element through an intermediate network element (for example, an NEF network element). It is worth noting that what the intermediate network element sends to the SF network element may be the information itself received by the intermediate network element from the AF network element, or it may be information generated by the intermediate network element based on the information sent by the AF network element. This will not be elaborated in the following text.

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

[0168] In implementation 2.2, the method further includes: the SF network element determining the first information based on the perception data corresponding to the perception service. This implementation can be applied to a case where the SF network element has the ability to determine the perception result based on the perception data. In this case, the SF network element can determine the perception result based on the perception data (for example, if the perception data is point cloud information, the SF network element can determine the perception result based on the point cloud information), so that the SF network element can determine the first information based on the perception result. In addition, for a specific description of the method for determining the first information, please refer to the aforementioned related description and will not be repeated here.

[0169] In an optional implementation, the SF network element determines the transmission resources that need to be adjusted to be allocated to the perception service based on the first information and the demand for the perception service, including: the SF network element determines whether the demand for the perception service is met based on the first information and the demand for the perception service; if the demand for the perception service is not met, determines the transmission resources that need to be adjusted to be allocated to the perception service.

[0170] In addition, in the embodiment of the present application, the demand for the perception service is met, which can also be understood as: all demands for the perception service are met. The demand for the perception service is not met, which can also be understood as: some or all of the demands for the perception service are not met. For example, the demands for perception service #1 are: the demand for the missed detection rate corresponding to perception service #1, the demand for the false detection rate corresponding to perception service #1, and the demand for the refresh rate corresponding to perception service #1. The demand for perception service #1 is met, which can also be understood as: the demands for the missed detection rate, false detection rate, and refresh rate corresponding to perception service #1 are all met. The demand for perception service #1 is not met, which can also be understood as: the demands for one or more of the missed detection rate, false detection rate, and refresh rate corresponding to perception service #1 are not met.

[0171] In addition, in the embodiment of the present application, in the scenario where the demand for the perception service is not met, adjusting the transmission resources allocated for the perception service may include increasing the transmission resources allocated for the perception service. It is understandable that in the scenario where the demand for the perception service is not met, increasing the transmission resources allocated for the perception service is conducive to meeting the demand for the perception service.

[0172] In addition, in the embodiments of the present application, transmission resources may include resources for transmitting perception signals and / or resources for receiving reflected signals corresponding to the perception signals. Transmission resources may, for example, be time domain resources and / or frequency domain resources and / or spatial domain resources, or resources in other domains, without limitation. Transmission resources may also be understood as air interface resources. This description will not be repeated herein.

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

[0174] In implementation 3.1, the SF network element determines whether the demand for the sensing service is met based on the error event information and the demand for the sensing service.

[0175] For example, the demand for the perception service is: the demand for the missed detection rate corresponding to the perception service. The demand for the missed detection rate corresponding to the perception service is: the missed detection rate is less than or equal to 5%. For example, measurement window #1 includes 20 time series. Based on the error event information, it is determined that: there are actually 2 time series in these 20 time series that have missed detection events, and the missed detection rate is 10%; it can be seen that the missed detection rate corresponding to measurement window #1 does not meet the requirement for the missed detection rate, so it can be determined that for measurement window #1, the demand for the perception service is not met. For another example, measurement window #2 includes 40 time series. Based on the error event information, it is determined that: there is actually 1 time series in these 40 time series that has a missed detection event, and the missed detection rate is 2.5%; it can be seen that the missed detection rate corresponding to measurement window #2 meets the requirement for the missed detection rate, so it can be determined that for measurement window #2, the demand for the perception service is met.

[0176] For another example, error event information is sent from the AF network element to the SF network element. Each time the AF network element identifies an error event, it sends the error event to the SF network element. The missed detection rate requirement for the perception service is less than or equal to 5%. Measurement window #1 includes 20 time series. When the SF network element receives the second missed detection event for measurement window #1, it determines that the perception service requirement is not met.

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

[0178] For example, the demand for the perception service is: the demand for the missed detection rate corresponding to the perception service. The demand for the missed detection rate corresponding to the perception service is: the missed detection rate is less than or equal to 5%. For example, for measurement window #1, the missed detection event ratio is 10%; it can be seen that the missed detection rate corresponding to measurement window #1 does not meet the missed detection rate requirement, and thus it can be determined that the demand for the perception service is not met for measurement window #1. For another example, for measurement window #2, the missed detection event ratio is 2.5%; it can be seen that the missed detection rate corresponding to measurement window #2 meets the missed detection rate requirement, and thus it can be determined that the demand for the perception service is met for measurement window #2.

[0179] In implementation method 3.3, the SF network element determines whether the demand for the perception service is met based on the performance parameters that do not meet the demand and the demand for the perception service. It is understandable that if the performance parameters that do not meet the demand are not defaulted in the first information, it means that there are performance parameters that do not meet the demand, and thus it can be determined that the demand for the perception service is not met. Exemplarily, in the scenario where the first information is sent by the AF network element to the SF network element, if the performance parameters that do not meet the demand are not defaulted in the first information received by the SF network element from the AF network element, the SF network element can determine that there are performance parameters that do not meet the demand, and thus determine that the demand for the perception service is not met.

[0180] In addition, in an optional manner, if the demand for the perception service is met, the SF network element may send fifth information to the perception device, where the fifth information is used to request a reduction in the transmission resources allocated for the perception service, thereby facilitating avoiding resource waste caused by over-allocation of transmission resources for the perception service. Alternatively, if the demand for the perception service is met, the SF network element may not send the fifth information to the perception device.

[0181] In an optional implementation, the SF network element may determine whether it is necessary to adjust the transmission resources allocated for the perception service based on the first information and the demand for the perception service; if it is necessary to adjust the transmission resources allocated for the perception service, execute step S102.

[0182] S102: The SF network element sends second information to the sensing device, where 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 perception service. This approach can be applied to a scenario where an SF network element determines that the transmission resources allocated for the perception service need to be adjusted when the demand for the perception service is not met. It is understandable that in a scenario where the demand for the perception service is not met, increasing the transmission resources allocated for the perception service is conducive to meeting the demand for the perception service.

[0184] In an optional embodiment, the second information includes one or more of the following: a performance parameter that does not meet the requirements, and a gap between the performance parameter that does not meet the requirements and the requirements. Optionally, the performance parameter that does not meet the requirements can be determined based on the first information. For a detailed description, please refer to the relevant description above and 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 value of the performance parameter that does not meet the requirements, without limitation.

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

[0186] Optionally, the second information also includes identification information of the perception service. This embodiment facilitates the perception device to determine the perception service for which the transmission resources are adjusted based on the identification information of the perception service. For a detailed description of the identification information of the perception service, please refer to the relevant description above and will not be repeated here.

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

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

[0189] In an optional implementation, the SF network element sending the second information to the sensing device includes: the SF network element sending the second information to the sensing device via an intermediate network element. Alternatively, the SF network element directly sends the second information to the sensing device without passing through the intermediate network element.

[0190] In addition, in an embodiment of the present application, in an implementation where the SF network element sends the second information to the perception device via the intermediate network element, the information sent by the intermediate network element to the perception device may be the second information itself received from the SF network element, or may be information generated based on the second information received from the SF network element, without limitation. For ease of explanation, the embodiment of the present application is described using an example in which the intermediate network element sends the second information itself received from the SF network element to the perception device.

[0191] In one optional manner, the sensing device is an access network device. The SF network element sends the second information to the access network device through an intermediate network element (e.g., an AMF network element). Alternatively, the SF network element sends the second information directly to the access network device without passing through the intermediate network element.

[0192] Exemplarily, in the process of establishing a perception 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, the next hop node to which the SF network element sends the second information is the AMF network element, and the SF network element records the address information or identification information of the AMF network element. 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 identification, etc.); wherein, the address information of the AMF network element may be, for example, a callback uniform resource identifier (callbackuniform 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., an AMF instance ID). For another example, the next hop node to which the SF network element sends the second information is the access network device, and the SF network element records the address information or identification information of the access network device. wherein, 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 identification (tunnel endpoint ID, TEID).

[0193] In another optional manner, the sensing device is a terminal device, and the SF network element sends the second information to the terminal device through an intermediate network element; or, the SF network element sends the second information directly to the terminal device without passing through the 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 a scenario where the SMF network element has subscribed to the update message of the perception 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 can 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 through 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 to the sensing service based on the second information.

[0198] The sensing device adjusts the transmission resources allocated for the sensing service, for example, including increasing the number of orthogonal frequency division multiplexing (OFDM) transmission symbols.

[0199] In an optional embodiment, the perception device is a terminal device, and the method further includes: the SF network element sends a second information to the access network device corresponding to the terminal device; accordingly, the access network device receives the second information from the SF network element. The access network device allocates transmission resources corresponding to the perception service to 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 resides. This embodiment can be applied to the scenario where the transmission resources used by the terminal device are resources controlled by the operator. In this scenario, the transmission resources used by the terminal device are allocated to 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 to 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 sending identification information of the terminal device to the access network device corresponding to the terminal device. The identification information of the terminal device may be, for example, a 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 may also be, for example, an identifier of an address of a channel allocated by the access network device to the terminal device.

[0201] In another optional manner, the SF network element sends the second information and the identification information of the terminal device to the AMF network element, wherein the identification information of the terminal device sent by the SF network element to the AMF network element may be, for example, the user permanent identification information (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, wherein the identification information of the terminal device sent by the AMF network element to the access network device may be, for example, RANUENGAPID or AMFUENGAPID. NGAP is the next generation application protocol. In an optional embodiment, the method further includes: the perception device sends third information to the SF network element, the third information being used to indicate whether the transmission resources allocated for the perception service are successfully adjusted; accordingly, the SF network element receives the third information from the perception device.

[0202] In an optional embodiment, the method further includes: the SF network element sending the perception data obtained using the adjusted transmission resources to the AF network element; the AF network element determining, based on the perception data obtained using the adjusted transmission resources, that the perception result is accurate or that the demand for the perception service is met, and sending fourth information or fifth information to the SF network element, wherein the fourth information indicates that the demand for the perception service is met, and the fifth information requests a reduction in the transmission resources allocated for the perception service. This method is applicable to the scenario where the AF network element sends the first information to the SF network element.

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

[0204] Alternatively, in another possible implementation, the AF network element may periodically count whether a perception result determined based on the received perception data is accurate. When the AF network element determines that the perception result is accurate, it may send the fourth information or the fifth information to the SF network element. The AF network element determines whether the perception result determined based on the received perception data is accurate by, for example, comparing the perception result with information obtained from other means, or with historical information, or with information obtained based on user feedback, to determine whether the perception result is accurate.

[0205] In an optional manner, the method further includes: the SF network element sending sixth information to the sensing device, where the sixth information is used to request a reduction in transmission resources allocated for the sensing service; thereby facilitating avoiding resource waste caused by over-allocation of transmission resources for the sensing service. In the scenario where the SF network element receives the fifth information, the sixth information may be the same as the fifth information, or may be information generated based on the fifth information.

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

[0207] In addition, optionally, the SF network element may also determine that the demand for the perception service is met in combination with 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 indicating that the demand for the perception service is not met, the SF network element may determine that the demand for the perception service is met.

[0208] In another optional embodiment, the method further includes: the SF network element determining, based on the perception data obtained through the adjusted transmission resources, that the demand for the perception service is met. This embodiment can be applied to a case where the SF network element has the ability to determine a perception result based on the perception data. In this case, the SF network element can determine the perception result based on the perception data, and thus the SF network element can determine, based on the perception result, that the demand for the perception service is met.

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

[0210] Alternatively, in another possible implementation, the SF network element may periodically count whether the perception result determined based on the received perception data is accurate. The SF network element determines whether the perception result determined based on the received perception data is accurate by, for example, comparing the perception result with information obtained from other means, or with historical information, or with information obtained based on user feedback, to determine whether the perception result is accurate.

[0211] In an optional manner, the method also includes: the SF network element sends sixth information to the perception device, and the sixth information is used to request a reduction in the transmission resources allocated for the perception service; thereby helping to avoid resource waste caused by excessive allocation of transmission resources for the perception service.

[0212] In another optional manner, the SF network element may not send the sixth information to the sensing device. This embodiment can be applied when the sensing device increases the transmission resources allocated for the sensing service in step S103 according to a step size. The step size can be predetermined or configured without limitation. This embodiment can also be applied in scenarios where the network is configured with a rule that no further interaction with the sensing device occurs when the sensing service requirements are met.

[0213] In addition, optionally, the SF network element can also determine that the demand for the perception service is met in combination with other information. For example, if the SF network element does not identify any information that the demand 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 demand for the perception service is met.

[0214] In summary, in information transmission method 100, the SF network element determines, based on first information and the demand for the perception service, that the transmission resources allocated to the perception service need to be adjusted. The first information includes one or more of the following: error event information, an error event ratio, or a performance parameter that does not meet the demand. 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 to the perception service.

[0215] It can be seen that after obtaining the perception data, this method can determine the transmission resources that need to be adjusted to be allocated to the perception service based on the first information determined based on the perception data and the demand for the perception service, and send the second information to the perception device, which is conducive to the perception device adjusting the transmission resources allocated to the perception service, so that the perception device perceives based on the adjusted transmission resources, which is conducive to meeting the demand for the perception service and thus improving the perception performance.

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

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

[0218] The first information includes one or more of the following: error event information, error event ratio, or performance parameter that does not meet the requirements. The first information is determined based on the perception data corresponding to the perception service. For a detailed description of the first information, please refer to the relevant description in information transmission method 100 and will not be repeated here.

[0219] In addition, the AF network element determines the transmission resources that need to be adjusted to be allocated to the perception service based on the first information and the demand 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 to be allocated to the perception service based on the first information and the demand for the perception service. For details, please refer to the specific description of the information transmission method 100 and will not be repeated here.

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

[0221] S202: The AF network element sends seventh information to the SF network element, where the seventh information is used to request adjustment of 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 embodiment, the seventh information is specifically used to request adjustment of transmission resources allocated to the perception service based on a first performance parameter, where the first performance parameter is a performance parameter that does not meet requirements. This is similar to the embodiment in which the second information is specifically used to request adjustment of transmission resources allocated to the perception service based on the first performance parameter in information transmission method 100. Reference is made to the relevant description thereof and is not repeated here.

[0223] In an optional embodiment, the seventh information includes one or more of the following: a performance parameter that does not meet the requirements, or a gap between the performance parameter that does not meet the requirements and the requirements. A detailed description 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 can be found in the relevant description of information transmission method 100 and is not repeated here.

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

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

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

[0227] S204: The sensing device adjusts the transmission resources allocated to the sensing service based on the eighth information. This is similar to the adjustment of the transmission resources allocated to the sensing service based on the second information in the information transmission method 100. For detailed description, please refer to the relevant description of the information transmission method 100 and will not be repeated here.

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

[0229] In addition, information transmission method 200 is similar to information transmission method 100, and for detailed description, reference may be made to the relevant description of information transmission method 100. Information transmission method 200 may also include the implementation of information transmission method 100, and for detailed description, reference may be made to the relevant description of information transmission method 100, which will not be repeated here.

[0230] To sum up, after obtaining the perception data, the information transmission method 200 can determine the transmission resources that need to be adjusted to be allocated for the perception service based on the first information determined based on the perception data and the demand for the perception service, and send the seventh information to the SF network element, which is conducive to adjusting the transmission resources allocated for the perception service, so as to perform perception based on the adjusted transmission resources, which is conducive to meeting the demand for the perception service and thus improving the perception performance.

[0231] This embodiment of the present application further provides an information transmission method 300. This information transmission method 300 differs from information transmission method 100 in that, in information transmission method 300, when a perception scenario corresponding to a perception service changes, the SF network element or the AF network element determines, based on network statistical information, that transmission resources allocated to the perception service need to be adjusted. For example, with reference to FIG8 , information transmission method 300 includes steps S301 to S303.

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

[0233] The perception scene may be, for example, a scene affected by factors such as weather, environment, and time, or a change in the perception scene may be a change in weather, environment, or time. Furthermore, the perception scene may also be understood as an external condition.

[0234] Network statistical information can be, for example, information based on experience (e.g., empirical values). During the deployment and debugging phase, the network can determine the correspondence between perception scenarios and transmission resources. When the perception scenario corresponding to a perception service changes, the SF network element can determine the transmission resources that need to be adjusted for the perception service based on the network statistical information. In this case, the SF network element does not need to identify every error event.

[0235] In an optional embodiment, the method may further include: the SF network element determining (or discovering) that the perception scenario corresponding to the perception service has changed. Alternatively, the method may further include: the SF network element obtaining information indicating the perception scenario change. Thus, the SF network element may be aware that the perception scenario corresponding to the perception service has changed. This embodiment of the present application does not limit the manner in which the SF network element is aware of the perception scenario change.

[0236] In an optional embodiment, a perception scenario corresponding to a perception service changes, including: the perception scenario corresponding to the perception service changes from a first perception scenario to a second perception scenario. The SF network element determines, based on network statistical information, that transmission resources allocated to the perception service need to be adjusted, including: the SF network element determining whether the transmission resources corresponding to the first perception scenario and the transmission resources corresponding to the second perception scenario are the same; if they are not the same, the SF network element determining that the transmission resources allocated to the perception service need to be adjusted.

[0237] For example, the perception scenario corresponding to the perception service changes from a sunny scene to a rainy scene, and the transmission resources corresponding to the rainy scene are more than the transmission resources corresponding to the sunny scene. Then, the SF network element can determine that the transmission resources allocated to the perception service need to be increased.

[0238] For another example, the perception scenario corresponding to the perception service changes from a clear road scenario to a congested road scenario, and the transmission resources corresponding to the congested road scenario are more than the transmission resources corresponding to the change in the clear road scenario. Then, the SF network element can determine that the transmission resources allocated to the perception service need to be increased.

[0239] For another example, the perception scenario corresponding to the perception service changes from the noon scenario to the evening peak scenario, and the transmission resources corresponding to the evening peak scenario are more than the transmission resources corresponding to the noon scenario. Then, the SF network element can determine that the transmission resources allocated to the perception service need to be increased.

[0240] In an optional embodiment, sensing is performed based on the transmission resources corresponding to the sensing scenario in the network statistical information, thereby meeting the demand for the sensing service in the sensing scenario. For example, if the sensing scenario corresponding to the sensing service is sensing scenario #1, the transmission resources corresponding to sensing scenario #1 are allocated to the sensing service. Thus, sensing is performed based on the transmission resources corresponding to sensing scenario #1, thereby meeting the demand for the sensing service. If the sensing scenario corresponding to the sensing service is sensing scenario #2, the transmission resources corresponding to sensing scenario #2 are allocated to the sensing service. Thus, sensing is performed based on the transmission resources corresponding to sensing scenario #2, thereby meeting the demand for the sensing service.

[0241] In an optional embodiment, the N perception scenarios in the network statistical information correspond to the perception services. Exemplarily, the network statistical information may include N perception scenarios corresponding to each perception service in one or more perception services, and transmission resources corresponding to each perception scenario, wherein 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 may determine the perception service whose perception scenario has changed from one or more perception services, and thereby 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 corresponding to the perception service.

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

[0243] Table 2

[0244] Based on Table 2, for example, in perception scenario #1, the transmission resource allocated to perception service #1 is transmission resource #1. Thereafter, the SF network element detects that the perception scenario corresponding to perception service #1 has changed from perception scenario #1 to perception scenario #2. The SF network element can determine from network statistical information that, for perception service #1, the transmission resource corresponding to perception scenario #2 is transmission resource #2. If transmission resource #2 is greater than transmission resource #1, the SF network element determines that the transmission resources allocated to perception service #1 need to be increased. If transmission resource #2 is less than transmission resource #1, the SF network element determines that the transmission resources allocated to perception service #1 need to be reduced. If transmission resource #2 is the same as transmission resource #1, the SF network element determines that the transmission resources allocated to perception service #1 do not need to be adjusted.

[0245] In an optional embodiment, the network statistical information also includes perception demands corresponding to N perception scenarios. Perception is performed based on the transmission resources corresponding to the perception scenarios in the network statistical information, and the perception demands corresponding to the perception scenarios can be met. For example, if the demand for perception service #1 is the first demand, the SF network element can determine the perception scenario corresponding to the first demand based on the network statistical information, and based on the transmission resources corresponding to the perception scenario corresponding to the first demand, determine whether the transmission resources allocated to perception service #1 need to be adjusted to meet the demand for perception service #1.

[0246] For example, the network statistics are shown in Table 3.

[0247] Table 3

[0248] Based on Table 3, for example, the demand for the perception service is demand #2. Under demand #2, in perception scenario #1, the transmission resource allocated for perception service #1 is transmission resource #3. Subsequently, the SF network element detects that the perception scenario corresponding to perception service #1 has changed from perception scenario #1 to perception scenario #2. The SF network element determines from network statistics that, under demand #2, the transmission resource corresponding to perception scenario #2 for perception service #1 is transmission resource #4. If transmission resource #4 is greater than transmission resource #3, the SF network element determines that the transmission resources allocated for perception service #1 need to be increased. If transmission resource #4 is less than transmission resource #3, the SF network element determines that the transmission resources allocated for perception service #1 need to be reduced. If transmission resource #4 is the same as transmission resource #3, the SF network element determines that the transmission resources allocated for perception service #1 do not need to be adjusted.

[0249] In an optional implementation, when the perception scenario corresponding to the perception service changes, the SF network element may determine whether it is necessary to adjust the transmission resources allocated to the perception service; if it is necessary to adjust the transmission resources allocated to the perception service, execute step S302.

[0250] S302. The SF network element sends ninth information to the perception device, where the ninth information is used to request adjustment of transmission resources allocated to the perception service.

[0251] Optionally, the ninth information includes a policy for adjusting the transmission resources allocated to the perception service. For example, based on Table 2, if the SF network element detects that the perception scenario corresponding to perception service #1 changes from perception scenario #1 to perception scenario #2, and that transmission resources #2 are greater than transmission resources #1, the ninth information may include the number of transmission resources that need to be increased in the transmission resources allocated to perception service #1, where the number of transmission resources that need to be increased is the difference between the number of transmission resources #2 and the number of transmission resources #1.

[0252] S303: The sensing device adjusts the transmission resources allocated to the sensing service based on the ninth information.

[0253] In another optional embodiment, in information transmission method 300, the AF network element determines, based on network statistical information, the transmission resources that need to be adjusted for the sensing service. For example, as shown in FIG9 , information transmission method 300 includes steps S401 to S404. The information transmission method 300 shown in FIG9 is similar to the information transmission method 300 shown in FIG8 . For a detailed description, reference may be made to the relevant description of the information transmission method 300 shown in FIG8 , and will not be repeated here.

[0254] S401: When a perception scenario corresponding to a perception service changes, the AF network element determines, based on network statistical information, that transmission resources allocated to the perception service need to be adjusted, wherein the network statistical information includes N perception scenarios and transmission resources corresponding to the N perception scenarios, where N is an integer greater than 1.

[0255] In an optional manner, when the perception scenario corresponding to the perception service changes, the AF network element can determine whether the transmission resources allocated to the perception service need to be adjusted; if the transmission resources allocated to the perception service need to be adjusted, execute step S402.

[0256] S402: The AF network element sends tenth information to the SF network element, where the tenth information is used to request adjustment of transmission resources allocated for the perception service. Correspondingly, the SF network element receives the tenth information from the AF network element.

[0257] S403: The SF network element sends eleventh information to the sensing device. The eleventh information is used to request adjustment of the transmission resources allocated for the sensing service. Accordingly, the sensing device receives the eleventh information from the SF network element. The eleventh information may be the same as the tenth information, or may be information generated by the SF network element based on the tenth information.

[0258] S404: The sensing device adjusts the transmission resources allocated to the sensing service based on the eleventh information.

[0259] To sum up, the information transmission method 300 can determine the transmission resources that need to be adjusted to be allocated to the perception service based on network statistical information when the perception scenario corresponding to the perception service changes, and send information for requesting adjustment of the transmission resources allocated to the perception service. This is conducive to adjusting the transmission resources allocated to the perception service, thereby facilitating the matching of the adjusted transmission resources with the changed perception scenario, and further conducive to meeting the demand for the perception service, thereby improving the perception performance.

[0275] S511. The AF network element determines (or discovers) that the sensing result determined based on the sensing data #2 is correct. It is understandable that the AF network element determines that the requirement for the sensing service is met based on the sensing data #2.

[0277] S513. The SF network element determines, based on the fourth information, that the transmission resources allocated to the perception service need to be reduced.

[0278] In addition, the SF network element may also determine, based on the fourth information, that a confirmation message needs to be sent to the sensing device. The confirmation message may include: identification information of the sensing service and indication information indicating that the requirement for the sensing service is met.

[0279] S514: The SF network element further sends sixth information to the sensing device, where the sixth information is used to request a reduction in transmission resources allocated for the sensing service.
