[0103] 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.

[0104] 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.

[0105] 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.

[0106] The UDM network element is responsible for managing contract data and notifying the corresponding network element when the contract data is modified.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In addition, the communication system to which the embodiments of the present application are applicable further includes a sensing function (SF) network element. The SF supports some or all of the following functions: session management functions for sensing data transmission (e.g., determining the QoS of transmitted sensing data, etc.), managing sensing accuracy parameters (e.g., obtaining corresponding sensing accuracy that can be processed by the network side based on the requirements of the AF network element), and processing sensing data (e.g., converting sensing measurement data into final target sensing result information).

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] The following describes an embodiment of the present application in detail with reference to the accompanying drawings. While the present application uses SF network elements and access network devices as examples of the execution entities to illustrate the corresponding methods, the present application does not limit the execution entities 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 in implementing the corresponding method, or a logic module or software that can implement all or part of the functions of the network element / device.

[0116] Please refer to FIG3 , 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.

[0117] S101. The SF network element obtains first information, where the first information is used to indicate a demand for a perception service requested to be established.

[0118] In an optional implementation manner, the first information includes one or more of the following: information related to perceived service quality, information related to perceived data transmission control, or information related to perceived data.

[0119] Information related to the quality of perception services includes the type of perception service and / or the requirements for the perception service. Examples of perception services include Internet of Vehicles services and drone intrusion detection services. Requirements for perception services include, for example, requirements for positioning accuracy, velocity measurement accuracy, perception resolution, and latency. In some scenarios, the requirements for perception services can be understood as the need to perform perception measurements, which are used to obtain perception data for the perception services.

[0120] Perceptual data transmission control related information is used to indicate the need for transmitting perceptual data. For example, the frequency of transmitting perceptual data is single transmission of perceptual data, or periodic transmission of perceptual data, or triggered transmission of perceptual data. Among them, triggered transmission of perceptual data can be understood as: transmitting perceptual data when the triggering condition is met. For example, the triggering condition for the access network device to transmit perceptual data is: obtaining information for requesting the transmission of perceptual data, that is, the access network device transmits perceptual data when / after obtaining the information for requesting the transmission of perceptual data. In addition, in an embodiment of the present application, the transmitted perceptual data may be uplink transmission perceptual data, and uplink transmission perceptual data may also be understood as reported perceptual data. For example, the access network device transmits perceptual data, which may be: the access network device sends perceptual data to the UPF network element or the SF network element. The UPF network element may, for example, be a perceptual UPF network element (i.e., a Sensing-UPF network element). This will not be described in detail later.

[0121] 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 collection 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 descriptive information of the measured object includes: the speed, size, reflection cross-sectional area, etc. of the object. The final measurement result can also be, for example, descriptive information of an event, for example, the descriptive information of the event is used to describe whether there is an intruder in a given perception area; or, the descriptive information of the event is used to describe a drawn three-dimensional (3D) map.

[0122] In addition, the first information may include not only the content already mentioned, but also other requirements for the perception service, without limitation.

[0123] 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 access network device through perception collection for the perception service, or the perception data may be obtained by the access network device through perception collection based on its own capabilities and then used for the perception service, without limitation.

[0124] In an optional implementation, the SF network element obtaining the first information includes: the SF network element receiving the first information from the AF network element. Furthermore, in the embodiments of the present application, "AF network element" may also be replaced by "application server," "third-party application," "data collector," or "application requester," and will not be further described below.

[0125] Optional approach a: the AF network element directly sends the first information to the SF network element. This approach can be applied to the case where the AF network element is located in a trust domain of the network. In this case, the AF network element can directly send the first information to the SF network element in the network.

[0126] Optional method b: The AF network element sends the first information to the SF network element through the intermediate network element. For example, the AF network element sends the first information to the SF network element through the NEF network element. Specifically, the AF network element sends the first information to the NEF network element, and correspondingly, the NEF network element receives the first information from the AF network element. Thereafter, the NEF network element sends the first information to the SF network element. In addition, it is worth noting that what the NEF network element sends to the SF network element may be the first information itself received by the NEF network element from the AF network element, or it may be information generated by the NEF network element based on the first information sent by the AF network element. For ease of explanation, the embodiment of the present application is explained by taking the example of the SF network element receiving the first information as an example. The case where the SF network element receives the information generated by the NEF network element based on the first information sent by the AF network element is similar and will not be repeated.

[0127] Optionally, the method further includes: the NEF network element authenticates the AF network element. In this manner, after the NEF network element successfully authenticates the AF network element, the NEF network element may send information (e.g., first information) from the AF network element to the SF network element, or the NEF network element processes the information from the AF network element and then sends it to the SF network element. Exemplarily, the NEF network element authenticates the AF network element, including: the NEF network element authenticates relevant information of the AF network element (e.g., the NEF network element determines whether the AF network element is authorized to request a perception service), and / or the NEF network element authenticates information sent by the AF network element (e.g., the NEF network element determines whether the AF network element is allowed to request a perception service of a certain accuracy).

[0128] In addition, the embodiments of the present application do not limit the manner in which the SF network element obtains the first information. In addition to the manner in which the SF network element receives the first information, the SF network element can also obtain the first information through other means, for example, the SF network element locally configures the first information, or the SF network element signs the first information, or the SF network element obtains the first information through the UDM network element.

[0129] In an optional implementation, the method further includes: the SF network element obtaining one or more of the following: first perception area information, address information of the AF network element, or start time of the perception service.

[0130] Among them, the first perception area information is information of tracking area (TA) granularity, or information of cell granularity (for example, including cell ID), or it can also be information of other granularity that can be understood by network elements in the network, without limitation.

[0131] The address information of the AF network element is used to indicate the destination address of the perception data to be sent ( / reported) by the SF network element after the perception data is collected. The embodiment of the present application does not limit the representation form of the address information of the AF network element. For example, the Internet Protocol (IP) address and port number information corresponding to the AF network element are used to represent the address information of the AF network element. For another example, the fully qualified domain name (FQDN) information corresponding to the AF network element is used to represent the address information of the AF network element, and the FQDN information is, for example, somehost.example.com. For another example, the application (identity, ID) information corresponding to the AF network element is used to represent the address information of the AF network element. In addition, it is worth noting that in the embodiment of the present application, what the SF network element sends ( / reports) to the AF network element may be the perception data collected by the SF network element itself, or it may be the data processed by the SF network element on the collected perception data, and there is no limitation on this.

[0132] Optionally, the SF network element obtains the address information of the AF network element and / or the start time of the perceived service, including: the SF network element receives the address information of the AF network element and / or the start time of the perceived service sent by the AF network element. Similar to the aforementioned SF network element receiving the first information from the AF network element, it will not be repeated here. However, the embodiment of the present application does not limit the manner in which the SF network element obtains the address information of the AF network element and / or the start time of the perceived service. In addition to the manner in which the SF network element receives the address information of the AF network element and / or the start time of the perceived service, the SF network element can also obtain the address information of the AF network element and / or the start time of the perceived service through other means, for example, the SF network element locally configures the address information of the AF network element and / or the start time of the perceived service, or the SF network element contracts the address information of the AF network element and / or the start time of the perceived service, or the SF network element obtains the address information of the AF network element and / or the start time of the perceived service through the UDM network element.

[0133] Optionally, the SF network element obtains the first perception area information, including: the SF network element receives the first perception area information 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 a trust domain of the network. In this case, the AF network element can directly send the first perception area information to the SF network element in the network.

[0134] Optionally, the SF network element obtains the first perception area information, including: the SF network element receives the first perception area information from the NEF network element. Specifically, the AF network element sends third perception area information to the NEF network element; if the NEF network element successfully authenticates the AF network element, the NEF network element determines the first perception area information based on the third perception area information, and sends the first perception area information to the SF network element. The third perception area information can be information at a TA granularity, or at a cell granularity, or at a geographic area granularity, or at a geographic address granularity, or can also be information at other granularities, without limitation.

[0135] The first perception area information is the same as or different from the third perception area information. For example, the third perception area information is information of TA granularity, or information of cell granularity, or information of other granularity that can be understood by network elements in the network, and the first perception area information can be the same as the third perception area information. For another example, the third perception area information is information of geographic area granularity or geographic address granularity, or information of other granularity that cannot be understood by network elements in the network, and the first perception area information is different from the third perception area information; understandably, after the NEF network element receives the third perception area information from the SF network element, it adjusts the third perception area information that cannot be understood by network elements in the network to the first perception area information that can be understood by network elements in the network, and then sends the first perception area information to the SF network element.

[0136] In addition, the embodiments of the present application do not limit the manner in which the SF network element obtains the first perception area information. In addition to the manner in which the SF network element receives the first perception area information, the SF network element can also obtain the first perception area information through other means, for example, the SF network element locally configures the first perception area information, or the SF network element signs a contract for the first perception area information, or the SF network element obtains the first perception area information through the UDM network element.

[0137] In an optional implementation, the method further includes: the SF network element obtaining information for requesting to establish the perception service.

[0138] Optional method a: The AF network element directly sends information for requesting the establishment of the perception service to the SF network element. This embodiment can be applied to the case where the AF network element is located in the trust domain of the network. Optionally, the information for requesting the establishment of the perception service also carries one or more of the following: the first information, the first perception area information, the address information of the AF network element, or the start time of the perception service.

[0139] Optional method b: The AF network element sends information for requesting to establish a sensing service to the intermediate network element, and the intermediate network element sends information for requesting to establish a sensing service to the SF network element. The intermediate network element may be, for example, an NEF network element and / or a UDM network element, and the information for requesting to establish a sensing service sent by the NEF network element and / or the UDM network element to the SF network element may be, for example, a sensing session establishment request (i.e., Nsf_SensingSession_Create request) message.

[0140] Optionally, the information sent by the AF network element to the intermediate network element for requesting to establish the perception service further carries one or more of the following: the first information, the third perception area information, the address information of the AF network element, or the start time of the perception service. Optionally, the information sent by the intermediate network element to the SF network element for requesting to establish the perception service further carries one or more of the following: the first information, the first perception area information, the address information of the AF network element, or the start time of the perception service, wherein the first perception area information is determined based on the third perception area information.

[0141] Optional approach c: The SF network element obtains information for requesting to establish the awareness service through network configuration. Exemplarily, the information for requesting to establish the awareness service may be provided to the SF network element by an operation and maintenance (OAM) system.

[0142] In addition, for the specific description of the first information, the first perception area information, the third perception area information, the address information of the AF network element, and the start time of the perception service, please refer to the above-mentioned related descriptions and will not be repeated here.

[0143] In an optional embodiment, the method further includes: the NEF network element determines the SF network element. This method can be applied to the scenario where the NEF network element authenticates the AF network element, which is beneficial for the NEF network element to receive information from the AF network element (for example: the first information, the third perception area information, the address information of the AF network element, the start time of the perception service, and the information for requesting to establish the perception service). After that, the information (for example: the first information, the first perception area information, the address information of the AF network element, the start time of the perception service, and the information for requesting to establish the perception service) can be sent to the determined SF network element. In addition, for the specific description of the first information, the first perception area information, the third perception area information, the address information of the AF network element, the start time of the perception service, and the information for requesting to establish the perception service, please refer to the aforementioned related description and will not be repeated here.

[0144] Optionally, the NEF network element determines the SF network element, including: the NEF network element determines the SF network element based on the first sensing area information. The following describes a manner in which the NEF network element determines the SF network element based on the first sensing area information, as shown in the following optional implementations 1.1 to 1.2.

[0145] In embodiment 1.1, the NEF network element determines the SF network element based on the first sensing area information, including: the NEF network element sends the first sensing area information to a third network element (e.g., an NRF network element); the third network element selects M SF network elements based on the first sensing area information and NF description information corresponding to the N SF network elements; the third network element sends information of the M SF network elements to the NEF network element; and the NEF network element selects a SF network element from the M SF network elements, where N is a positive integer and M is a positive integer less than or equal to N.

[0146] Among them, the NF description information (NF profile) corresponding to each SF network element in the N SF network elements includes the area information corresponding to the SF network element, and the area information corresponding to each SF network element is used to indicate the area corresponding to the SF network element. The area corresponding to each SF network element in the M SF network elements matches the area indicated by the first perception area information. In addition, in an embodiment of the present application, the area corresponding to the SF network element can also be understood as: the area covered by the SF network element, or the service area (service area) of the SF network element, or the set of areas (for example, TA, or cellID) corresponding to all access network devices to which the SF network element can be connected. The area corresponding to the SF network element matches the area indicated by the first perception area information, and can also be understood as: the area covered by the SF network element includes the area indicated by the first perception area information, or the service area of ​​the SF network element includes the area indicated by the first perception area information.

[0147] In addition, in the process of the third network element selecting M SF network elements, or in the process of the NEF network element selecting a SF network element from M SF network elements, the selection can also be made in combination with other information. For example, the load balancing of each SF network element can also be considered for selection without restriction.

[0148] For example, taking the third network element as an NRF network element, SF network element #1 corresponds to area #1, area #2, and area #3, SF network element #2 corresponds to area #1 and area #4, and SF network element #3 corresponds to area #2 and area #4. The area indicated by the first perception area information is area #1. Therefore, the area corresponding to SF network element #1 and the area corresponding to SF network element #2 both include area #1, which matches the area indicated by the first perception area information.

[0149] The NRF network element selects SF network element #1 and SF network element #2 from SF network element #1, SF network element #2, and SF network element #3, and sends the information of SF network element #1 and SF network element #2 to the NEF network element. The NEF network element determines SF network element #1 and SF network element #2 based on the information of SF network element #1 and SF network element #2. The NEF network element selects a SF network element from SF network element #1 and SF network element #2 based on factors such as load balancing.

[0150] Alternatively, the NRF network element determines SF network element #1 and SF network element #2 from SF network element #1, SF network element #2, and SF network element #3, and then selects SF network element #1 from SF network element #1 and SF network element #2 based on factors such as load balancing. The NRF network element sends the information of SF network element #1 to the NEF network element. The NEF network element determines SF network element #1 based on the information of SF network element #1 sent by the NEF network element.

[0151] Optionally, the information of the M SF network elements includes: an NF ID or an NF ID candidate list corresponding to each of the M SF network elements, and area information or NF description information corresponding to each SF network element. The NF ID can be represented by an IP address or a FQDN, for example.

[0152] Optionally, the method further includes: the NEF network element sending information indicating that the type of the network element to be determined is an SF network element to the third network element. In this way, the third network element can learn that the type of network element to be selected is an SF network element. In addition, the type of network element to be determined can also be understood as the type of network element to be selected or the type of network element to be discovered.

[0153] Implementation 1.2, the NEF network element determines the SF network element based on the first sensing area information, including: the NEF network element determines the SF network element based on the first sensing area information and local configuration information.

[0154] The local configuration information includes: NF description information corresponding to each SF network element in at least one SF network element locally configured by the NEF network element, the NF description information corresponding to each SF network element including area information corresponding to the SF network element, the area information corresponding to each SF network element being used to indicate an area corresponding to the SF network element. The area corresponding to the SF network element determined by the NEF network element matches the area indicated by the first description information.

[0155] In addition, optionally, in addition to the first sensing area information and the local configuration information, the NEF network element may also determine the SF network element based on / in combination with other information, without limitation. For example, the NEF network element determines the SF network element based on the first sensing area information, the local configuration information, and the identification information of the AF network element.

[0156] S102: The SF network element sends second information and third information to the access network device. The second information and third information are determined based on the first information. The second information indicates the QoS requirement for the perception service, and the third information indicates the QoS requirement for transmitting the perception data corresponding to the perception service. In response, the access network device receives the second information and third information from the SF network element.

[0157] In addition, the embodiments of the present application are not limited to the use of the name "QoS requirement", and other names can also be used. For example, "QoS requirement" can also be replaced with "demand" or "requirement", and there is no limitation on this. For example, "the second information is used to indicate the QoS requirement for the perception service" can also be replaced with: "the second information is used to indicate the demand for the perception service" or "the second information is used to indicate the requirement for the perception service". For another example, "the third information is used to indicate the QoS requirement for the perception data corresponding to the transmission perception service" can also be replaced with "the third information is used to indicate the demand for the perception data corresponding to the transmission perception service" or "the third information is used to indicate the requirement for the perception data corresponding to the transmission perception service".

[0158] In an optional embodiment, the second information includes one or more of the following: positioning accuracy information corresponding to the perception collection, speed measurement accuracy information, perception resolution information, refresh frequency of the perception service, missed detection rate, false alarm rate, transmission period of perception data, or transmission time of perception data.

[0159] Exemplarily, the positioning accuracy information is composed of the accuracy of the horizontal component and / or the accuracy of the vertical component, and the unit of accuracy is, for example, meter (m). The speed measurement accuracy information is composed of the velocity component of the horizontal component and / or the velocity component of the vertical component, and the unit of the velocity component is, for example, meter per second (m / s). The perception resolution information includes one or more of the following: distance resolution (unit is, for example, meter), velocity resolution (unit is, for example, meter per second), or angular resolution (unit is, for example, angle). The refresh frequency of the perception service is, for example, in seconds (s). The missed detection rate is used to indicate the ratio of missed detection events to all events in the process of obtaining perception results. For example, the missed detection rate can be expressed as a percentage. The false alarm rate is used to indicate the ratio of false alarm events to all events in the process of obtaining perception results. For example, the false alarm rate can be expressed as a percentage. The transmission period of perception data is used to indicate the period of periodic transmission of perception data. For example, the transmission period of perception data can be expressed using an exhaustive type (for example, 120ms, 240ms, ...). The transmission time of the sensing data is used to indicate the time for a single transmission of the sensing data or the time for a triggered transmission of the sensing data. Optionally, compared with the first information, the second information indicates a more specific demand for the sensing service.

[0160] In addition to the above-mentioned information, the second information may also include other information, without limitation. For example, the second information may also include requirements for the time between triggering the sensing service and the availability of the sensing result, and requirements for the frequency of transmitting sensing data. Requirements for the frequency of transmitting sensing data may include, for example, requirements for single-time transmission of sensing data, requirements for periodic transmission of sensing data, or requirements for triggered transmission of sensing data.

[0161] In addition, in embodiments of the present application, some of the aforementioned information may not only be part of the second information, but may also be information that is parallel to the second information. For example, in one embodiment, the second information includes the transmission period of the perception data and / or the transmission time of the perception data; in another embodiment, the transmission period of the perception data and / or the transmission time of the perception data are information that is parallel to the second information, and the second information does not include the transmission period of the perception data and / or the transmission time of the perception data.

[0162] In an optional embodiment, the method further includes: the SF network element determining the second information based on the first information. Exemplarily, the SF network element may internally implement the determination of the second information based on the first information. Alternatively, the SF network element may determine the second information based on the first information based on a local policy. Alternatively, the SF network element may determine the second information based on the first information based on a policy configured by an operator. Alternatively, the SF network element may determine the second information based on the first information based on other policy information (e.g., a policy obtained by other means). No limitation is imposed.

[0163] In an optional embodiment, the third information includes one or more of the following: a QoS identifier (QoS identifier) ​​corresponding to the perception data, 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 (5QI). In addition, in addition to the content already mentioned, the third information may also include other QoS requirements for the transmission of perception data, without limitation. The third information may also be referred to as QoS profile information.

[0164] The following is an exemplary explanation of the method for determining the third information, as described in the following optional implementations 2.1 to 2.3.

[0165] In implementation 2.1, the SF network element determines the third information based on the first information. It is understandable that the SF network element can internally implement the determination of the third information based on the first information. This implementation can be applied to the case where the SMF serves as a logical function of the SF network element.

[0166] In implementation 2.2, in conjunction with Figure 4, the SF network element determines fourth information based on the first information, and the SF network element sends the fourth information to the SMF network element; accordingly, the SMF network element receives the fourth information from the SF network element. The SMF network element determines third information based on the fourth information, and the SMF network element sends third information to the SF network element; accordingly, the SF network element receives the third information from the SMF network element. The fourth information is used to indicate the QoS requirements for the perception data of the transmission perception service. In addition, in the embodiment of the present application, the SMF network element can be, for example, a perception SMF network element (i.e., a sensing-SMF network element), which will not be described in detail below.

[0167] In implementation method 2.3, in combination with Figure 5, the SF network element sends the first information to the SMF network element; accordingly, the SMF network element receives the first information from the SF network element. The SMF network element sends the first information to the PCF network element; accordingly, the PCF network element receives the first information from the SMF network element. The PCF network element determines the fourth information based on the first information, and sends the fourth information to the SMF network element; accordingly, the SMF network element receives the fourth information from the PCF network element. The SMF network element determines the third information based on the fourth information, and sends the third information to the SF network element; accordingly, the SF network element receives the third information from the SMF network element. The fourth information is used to indicate the QoS requirements for the perception data of the transmission perception service. It can be seen that in implementation method 2.3, the PCF network element with policy control function performs the operation of determining the fourth information based on the first information, while the SF network element may not perform the operation of determining the fourth information based on the first information, which is conducive to simplifying the implementation logic of the SF network element.

[0168] In implementation 2.4, in combination with Figure 6, the SF network element sends the first information to the PCF network element; accordingly, the PCF network element receives the first information from the SF network element. The PCF network element determines the fourth information based on the first information, and sends the fourth information to the SMF network element; accordingly, the SMF network element receives the fourth information from the PCF network element. The SMF network element determines the third information based on the fourth information, and sends the third information to the SF network element; accordingly, the SF network element receives the third information from the SMF network element. The fourth information is used to indicate the QoS requirements for the perception data of the transmission perception service. Optionally, the SF network element can also provide the PCF network element with the identification information of the SMF network element, so that the PCF network element can send the fourth information to the SMF network element based on the identification information of the SMF network element.

[0169] In addition, in implementation mode 2.2, implementation mode 2.3, or implementation mode 2.4, the third information may be the same as the fourth information. It is understandable that the SMF network element does not adjust the received fourth information. In this case, the SMF network element may send the third information to the SF network element or may not send the third information to the SF network element without limitation.

[0170] Alternatively, the third information may be different from the fourth information. It is understood that the SMF network element adjusts the received fourth information to obtain the third information. Exemplarily, the fourth information specifically indicates the QoS requirement corresponding to a first channel used by an access network device to send perception data to an SF network element via a UPF network element. The third information specifically indicates the QoS requirement corresponding to a second channel used by an access network device to send perception data to a UPF network element.

[0171] Optionally, in implementation 2.2 or implementation 2.3 or implementation 2.4, the fourth information includes authorized QoS parameters. Exemplarily, the fourth information includes QoS parameters corresponding to the perception data or a QoS reference, wherein the QoS parameters corresponding to the perception data include one or more of the following: a QoS identifier corresponding to the perception data (e.g., 5QI), an allocated retention priority, a guaranteed bit rate, and a maximum bit rate. Optionally, the fourth information may also refer to the QoS information of the PDU session. In addition, the fourth information may also be referred to as authorized QoS information reported by the perception data, or QoS information corresponding to the channel used to transmit the perception data.

[0172] Optionally, in implementation 2.2 or implementation 2.3 or implementation 2.4, the method further includes: the SF network element determines the SMF network element based on the first perception area information. This is similar to the aforementioned NEF network element determining the SF network element based on the first perception area information. For details, please refer to the aforementioned relevant explanation of the NEF network element determining the SF network element based on the first perception area information, which will not be repeated here. In addition, in addition to determining the SMF network element based on the first perception area information, the SF network element can also determine the SMF network element in other ways. For example, it can also be to configure the SMF network element information for the SF network element in advance, and there is no limitation on this.

[0173] The following describes how the SF network element sends the second information and the third information to the access network device, as described in the following optional implementation 3.1 and implementation 3.2.

[0174] Implementation method 3.1, the SF network element sends the second information and the third information to the access network device, including: the SF network element sends the second information and the third information to the AMF network element, and accordingly, the AMF network element receives the second information and the third information from the SF network element. The AMF network element sends the second information and the third information to the access network device, and accordingly, the access network device receives the second information and the third information from the AMF network element.

[0175] The number of AMF network elements can be one or more. It is understandable that the SF network element sends the second information and the third information to one or more AMF network elements, and one or more AMF network elements respectively send the second information and the third information to the access network devices they manage. For example, the SF network element sends the second information and the third information to AMF network element #1 and AMF network element #2, AMF network element #1 sends the second information and the third information to access network devices #1 and #2 managed by AMF network element #1, and AMF network element #2 sends the second information and the third information to access network devices #3 and #4 managed by AMF network element #1.

[0176] Optionally, the method further includes: the SF network element determines the AMF network element based on the first perception area information. This is similar to the manner in which the NEF network element determines the SF network element based on the first perception area information. For details, please refer to the aforementioned explanation of the NEF network element determining the SF network element based on the first perception area information, which will not be repeated here. In addition, the number of AMF network elements determined by the SF network element may be one or more.

[0177] Optionally, in an embodiment of the present application, the second information and the third information sent by the AMF network element to the access network device may be carried in a first request message sent by the AMF network element to the access network device. The first request message is used to request the access network device to configure parameters for perception, and / or to request the access network device to perform perception. The first request message may be, for example, a next generation application protocol (NGAP) sensing request message. The first request message may also be named by other names without limitation.

[0178] In addition, in addition to being an AMF network element that sends the second information and the third information to the access network device through the AMF network element, the SF network element can also send the second information and the third information to the access network device through one or more other intermediate network elements, and there is no restriction on this.

[0179] In embodiment 3.2, the SF network element sends the second information and the third information to the access network device, including: the SF network element directly sending the second information and the third information to the access network device. Exemplarily, the external interface of the SF network element is directly connected to the external interface of the access network device, and the SF network element directly sends the second information and the third information to the access network device without sending the second information and the third information to the access network device through an intermediate network element. Optionally, the method further includes: the SF network element selecting the access network device.

[0180] In addition, in the embodiment of the present application, the second information and the third information sent by the SF network element to the access network device can be two independent information elements (IEs), or can be a single information element. For example, the information element carrying the second information is also used to carry the third information, or the information element carrying the third information is also used to carry the second information element.

[0181] In an optional embodiment, the method further includes: the SF network element sending fifth information to the access network device, the fifth information being used to indicate a transmission mode of the perception data, the fifth information being determined based on the first information, and the transmission mode of the perception data including sending the perception data via a control plane or a user plane. Exemplarily, sending the perception data via the control plane can be understood as: the access network device sending the perception data to the SF network element via the AMF network element and the SMF network element. Sending the perception data via the user plane can be understood as: the access network device sending the perception data to the SF network element via the UPF network element.

[0182] Optionally, the method further includes: the SF network element determining fifth information based on the first information. Optionally, the SF network element determines the fifth information based on the perception data-related information in the first information, where the perception data-related information is used to indicate a requirement for the type of perception data to be transmitted. For details, please refer to the aforementioned related explanation and will not be repeated here.

[0183] For example, if the amount of sensory data is large, sending the sensory data via the user plane may be preferred to improve transmission efficiency. For example, if the sensory data-related information is used to request the reporting of point cloud information, which is generally large in data volume, sending the sensory data via the user plane may be preferred. For another example, if the sensory data-related information is specifically used to request the reporting of a rendered 3D map, which is generally large in data volume, sending the sensory data via the user plane may be preferred.

[0184] For example, if the amount of sensor data is small, sending the sensor data via the control plane may be preferred to improve transmission reliability. For example, if the sensor data-related information is specifically used to request whether there is an intruder in a given sensor area, the data volume is generally small, so sending the sensor data via the control plane may be preferred.

[0185] In addition, it should be noted that the embodiments of the present application are not limited to the method used to determine the transmission method of the perception data. For example, the transmission method of the perception data can also be determined based on the type of perception service in the first information, or the default transmission method of the perception data can include sending the perception data through the user plane, or the transmission method of the perception data can also be predefined.

[0186] In addition, the SF network element sends the fifth information to the access network device, which can be sent directly or indirectly through one or more intermediate network elements (for example, AMF network elements), without limitation. It is similar to the SF network element sending the second information and the third information to the access network device. Please refer to the above-mentioned related explanations and will not be repeated here.

[0187] In an optional embodiment, the method further includes: the SF network element sending one or more of the following to the access network device: second perception area information, sixth information, seventh information, or the start time of the perception service. The sixth information indicates the address of the next hop node to which the access network device sends perception data, and the seventh information indicates an identifier (ID) of a third tunnel used by the access network device to send perception data to the SF network element. The identifier of the third tunnel may also be referred to as an uplink tunnel ID (UL tunnel ID).

[0188] Optionally, the second perception area information is the same as the first perception area information, or the second perception area information is a subset of the first perception area information. For the specific explanation of the first perception area information, please refer to the aforementioned related explanation and will not be repeated here. It is understandable that the area indicated by the second perception area information is the same as the area indicated by the first perception area information, or the area indicated by the second perception area information is: a part of the area indicated by the first perception area information. For example, the SF network element sends the second perception area information to the access network device through the AMF network element, and the second perception area information is the same as the first area, or the area indicated by the second perception area is: an area in the area indicated by the first perception area information that matches the service area of ​​the AMF network element.

[0189] In one optional manner, the address of the next hop node to which the access network device sends the perception data, as indicated by the sixth information, is the address of the UPF network element, and the third channel is specifically used for the access network device to send the perception data to the SF network element via the UPF network element. This manner can be applied when the UPF network element and the SF network element are two independent network elements.

[0190] In another optional manner, the address of the next hop node to which the access network device sends the perception data, as indicated by the sixth information, is the address of the SF network element, and the third channel is used for the access network device to directly send the perception data to the SF network element. This manner can be applied when the UPF is a logical function in the SF network element.

[0191] Optionally, the sixth information and / or the seventh information is sent by the SMF network element to the SF network element.

[0192] In addition, the SF network element sends one or more of the following to the access network device: the second perception area information, the sixth information, the seventh information, or the start time of the perception service. It can be sent directly or indirectly through one or more intermediate network elements (for example, AMF network elements). There is no restriction. It is similar to the SF network element sending the second information and the third information to the access network device. Please refer to the above-mentioned related explanations and will not be repeated here.

[0193] In an optional embodiment, the method further includes: the SF network element sends information to the SMF network element for requesting the SMF network element to establish a context corresponding to the perception service. The SMF network element sends configuration information to the UPF network element, where the configuration information is used to configure the rules used by the UPF network element to transmit perception data. The UPF network element configures the corresponding rules based on the configuration information. Optionally, the method further includes: the UPF network element sends a response message to the SMF network element for indicating that the UPF network element configuration is complete, where the response message is a response message corresponding to the configuration information.

[0194] Among them, the information used to request the SMF network element to establish the context corresponding to the sensing service can be, for example, a sensing context establishment request (Nsmf_SensingContextCreate Request) message.

[0195] Among them, the configuration information includes one or more of the following: packet detection rule (PDR), forwarding action rule (FAR), QoS enforcement rule (QER). Optionally, the configuration information is determined based on the fourth information, and the fourth information is used to indicate the QoS requirements for the perception data of the transmission perception service. For the specific explanation of the fourth information, please refer to the above-mentioned related explanation and will not be repeated here. In addition, optionally, the configuration information sent by the SMF network element to the UPF network element can be carried in the N4x establishment request message or N4x modification request message sent by the SMF network element to the UPF network element.

[0196] Optionally, the information used to request the SMF network element to establish a context corresponding to the perception service also carries: the fourth information, and / or the eighth information, where the eighth information is used to indicate the address of the next hop node to which the UPF network element sends the perception data. The next hop node to which the UPF network element transmits the perception data is, for example, an SF network element or an AF network element.

[0197] Optionally, after the SMF network element receives the information for requesting the SMF network element to establish a context corresponding to the perception service, it also determines the third information based on the fourth information and sends the third information to the SF network element. The third information can be carried in a response message sent by the SMF network element to the SF network element, and the response message is a response message corresponding to the information for requesting the SMF network element to establish a context corresponding to the perception service. For a specific description of this method, please refer to the relevant description of the aforementioned implementation method 2.2 and will not be repeated here.

[0198] Optionally, after the SMF network element receives the information for requesting the SMF network element to establish the context corresponding to the perception service, it also determines the sixth information and / or the seventh information, and sends the sixth information and / or the seventh information to the SF network element. The sixth information is used to indicate the address of the next hop node to which the access network device sends the perception data, and the seventh information is used to indicate the identifier of the third channel, and the third channel is used for the access network device to send the perception data to the SF network element. Among them, the address of the next hop node to which the access network device sends the perception data and / or the identifier of the third channel can be allocated by the SMF network element, or can also be allocated by the UPF network element and sent to the SMF network element (for example, carried in a response message sent by the UPF network element to the SMF network element to indicate that the UPF network element configuration is complete). In addition, the sixth information and / or the seventh information sent by the SMF network element to the SF network element can be carried in a response message sent by the SMF network element to the SF network element. For the specific description of the sixth information and the seventh information, please refer to the above-mentioned related description and will not be repeated here.

[0199] In addition, in one possible implementation, if the network has already established resources for transmitting perception data in advance, the network may not need to establish resources for transmitting perception data after obtaining information for requesting the establishment of a perception service. For example, the network has already established an uplink transmission channel for perception data in advance (for example, by default, all perception services share the same channel for transmitting perception data). After the network obtains information for requesting the establishment of a perception service, it may not need to establish an uplink transmission channel for perception data. Specifically, the SF network element may not perform the operation of sending information to the SMF network element for requesting the SMF network element to establish a context corresponding to the perception service, the SMF network element may not perform the operation of sending configuration information to the UPF network element, and the UPF network element may not perform the operation of configuring corresponding rules based on the configuration information.

[0200] In an optional embodiment, the method further includes one or more of the following: configuring, by the access network device, parameters for sensing; enabling, by the access network device, a sensing service; or configuring, by the access network device, context information for transmitting sensing data. These operations may be determined by the access network device based on one or more of the following: the second information, the third information, the fifth information, the second sensing area information, the sixth information, the seventh information, or the start time of the sensing service.

[0201] For example, the access network device configures parameters for perception based on the second information.

[0202] For another example, the access network device starts the perception service based on the start time of the perception service.

[0203] For another example, the access network device can start the perception service after receiving the first request message. The first request message is used to request the access network device to configure parameters for perception, and / or to request the access network device to perform perception. This method can be applied to the scenario where the access network device has not received the start time of the perception service.

[0204] For another example, the access network device configures context information for transmitting perception data, including: the access network device allocates resources for uplink transmission.

[0205] In an optional embodiment, the method further includes: the access network device sending ninth information and / or tenth information to the SF network element; and the SF network element correspondingly receiving the ninth information and / or tenth information from the access network device. The ninth information indicates the QoS requirements for the perception service accepted by the access network device. The tenth information indicates the QoS requirements for the perception data corresponding to the transmission of the perception service accepted by the access network device.

[0206] In addition, the access network device can be sent directly to the SF network element, or it can be sent to the SF network element through the AMF network element, without limitation. It is similar to the access network device sending the second information and the third information to the SF network element. For details, please refer to the above-mentioned related explanations and will not be repeated here.

[0207] Optionally, the ninth information and / or the tenth information sent by the access network device to the SF network element is carried in an NGAP sensing response message sent by the access network device to the SF network element.

[0208] Optionally, the method further includes: the SF network element sending a tenth message to the SMF network element; and the SMF network element sending a tenth message to the UPF network element. This method can be applied to a scenario where some of the QoS requirements for the perception data corresponding to the transmission perception service are accepted by the access network device. The tenth message from the SF network element to the SMF network element can, for example, be carried in a perception modification message sent by the SF network element to the SMF network element. The tenth message sent by the SMF network element to the UPF network element can, for example, be carried in an N4x modification request message from the SMF network element to the UPF network element.

[0209] In summary, in information transmission method 100, the SF network element obtains first information indicating a requirement for the requested perception service. The SF network element then sends second and third information to the access network device. The second and third information are determined based on the first information. The second information indicates the QoS requirement for the perception service, and the third information indicates the QoS requirement for transmitting the perception data corresponding to the perception service.

[0210] It can be seen that this method determines the QoS requirements for the perception service and the QoS requirements for the transmission of perception data based on the demand for the perception service requested to be established, and sends the QoS requirements for the perception service and the QoS requirements for the transmission of perception data to the access network device, which is conducive to the access network device being able to perceive and transmit perception data based on the QoS requirements for the perception service and the QoS requirements for the transmission of perception data. It can be understood that the SF network element controls the access network device to perceive and transmit perception data based on the QoS requirements for the perception service and the QoS requirements for the transmission of perception data, so that the access network device can perceive and transmit perception data to meet the demand for the perception service. It can be seen that this method can establish perception services and improve perception performance.

[0211] In addition, the information transmission method 100 can be applied to scenarios where an access network device performs station-side perception, specifically, scenarios where the access network device autonomously transmits and receives perception signals (i.e., the access network device transmits a perception signal and receives a reflected signal of the perception signal). The access network device can perform station-side perception and report perception data based on the second information and the third information.

[0212] Please refer to FIG. 7 , which is a flow chart of an information transmission method 200 provided in an embodiment of the present application. The information transmission method 200 includes the following steps.

[0213] S201. The SF network element obtains first information, where the first information is used to indicate a demand for a perception service requested to be established.

[0214] For the detailed description of S201, please refer to the relevant description of step S101 in the information transmission method 100 (including all the contents between step S101 and step S102), which will not be repeated here.

[0215] S202: The SF network element sends second information and identification information to the access network device. The second information is determined based on the first information, the second information is used to indicate the QoS requirement for the perception service, and the identification information is used to identify the perception service. In response, the access network device receives the second information and identification information from the SF network element.

[0216] Among them, the identification information is, for example, a sensing ID, which can represent a specific (internal operator) sensing service. Exemplarily, the numbering rule of the sensing ID is a combination of the operator identifier and the sensing service identifier, where the "sensing service identifier" can also be understood as the "sensing service identifier." For example, the sensing ID can be expressed as: [operator identifier] [sensing service identifier], where each field can be represented by a binary, octal, decimal, or hexadecimal number.

[0217] In an optional embodiment, the method further includes: the SF network element determining identification information. It is understandable that the identification information of the awareness service can be generated by the SF network element. In one possible implementation method, the operator pre-configures the range of awareness service identifiers that can be assigned by the SF network element; after the SF network element obtains the first information or information for requesting establishment of the awareness service, the SF network element assigns an unassigned awareness service identifier as the identification information of the awareness service.

[0218] For example, using binary digits to represent the perception service identifier, the operator pre-configures the range of perception service identifiers that can be assigned by SF network element #1 to be 000 to 111 (binary). Within the range 000 to 111, the range of perception service identifiers that have not yet been assigned is 100 to 111. Therefore, after obtaining first information #1 (first information #1 is used to indicate a demand for perception service #1) or information for requesting the establishment of perception service #1, SF network element #1 can select a perception service identifier from 100 to 111 as the identification information for perception service #1. For example, SF network element #1 selects "101" from 100 to 111 as the identification information for perception service #1. For a detailed description of the second information, please refer to the relevant description of the second information in information transmission method 100 and will not be repeated here. For a detailed description of the SF network element sending the second information and identification information to the access network device, please refer to the relevant description of the SF network element sending the second information to the access network device in information transmission method 100 and will not be repeated here.

[0219] S203: The SF network element sends identification information and the first information or the third information to the SMF network element. The first information is used to determine the third information, and the third information is used to indicate the QoS requirement for the perception data corresponding to the transmission perception service. Correspondingly, the SMF network element receives the identification information and the first information or the third information from the SF network element.

[0220] S204: The SMF network element sends identification information and fourth information to the access network device, where the fourth information is determined based on the third information and is used to indicate QoS requirements for the perception data corresponding to the transmission perception service. Accordingly, the access network device receives the identification information and fourth information from the SMF network element.

[0221] As can be seen, the identification information is used to associate the second information with the fourth information. The access network device can associate the second information with the fourth information based on the identification information. It is understandable that the access network device can determine that the perceived service corresponding to the second information and the perceived service corresponding to the fourth information are the same based on the identification information.

[0222] For example, an access network device receives identification information #1 and second information #1 associated with identification information #1 from an SF network element. It also receives identification information #2 and second information #2 associated with identification information #2 from an SF network element. It also receives identification information #1 and fourth information #1 associated with identification information #1 from an SMF network element. It also receives identification information #2 and fourth information #2 associated with identification information #2 from an SMF network element. Based on identification information #1, the access network device can determine that second information #1 and fourth information #1 correspond to the same perceived service. Based on identification information #2, the access network device can determine that second information #2 and fourth information #2 correspond to the same perceived service.

[0223] In addition, the information transmission method 200 is similar to the information transmission method 100, and for a detailed description, reference may be made to the relevant description of the information transmission method 100. The difference between the information transmission method 200 and the information transmission method 100 is that: in the information transmission method 200, the SF network element sends the second information and identification information to the access network device, and the SF network element also sends the identification information and the first information or the third information to the SMF network element, so that the SMF network element sends the identification information and the fourth information (the fourth information is determined based on the third information) to the access network device.

[0224] In an optional embodiment, the third information is used to indicate the QoS requirements corresponding to the first channel, and the first channel is used for the access network device to send perception data to the SF network element through the UPF network element; the fourth information is specifically used to indicate the QoS requirements corresponding to the second channel, and the second channel is used for the access network device to send perception data to the UPF network element.

[0225] In an optional embodiment, the third information in the information transmission method 200 is different from the third information in the information transmission method 100, and the third information in the information transmission method 200 is the same as the fourth information in the information transmission method 100. For the specific description of the third information in the information transmission method 200, please refer to the specific description of the fourth information in the information transmission method 100, which will not be repeated here.

[0226] In an optional embodiment, the fourth information in the information transmission method 200 is different from the fourth information in the information transmission method 100, and the fourth information in the information transmission method 200 is the same as the third information in the information transmission method 100. For the specific description of the fourth information in the information transmission method 200, please refer to the specific description of the third information in the information transmission method 100, which will not be repeated here.

[0227] In an optional embodiment, the difference between the information transmission method 200 and the information transmission method 100 also includes: in the information transmission method 200, the SMF network element sends the sixth information and / or the seventh information to the access network device; the sixth information is used to indicate the address of the next hop node to which the access network device sends perception data; the seventh information is used to indicate the identifier of the third channel, and the third channel is used for the access network device to send perception data to the SF network element.

[0228] In addition, the information transmission method 200 may also include the implementation methods in the information transmission method 100. For detailed description, please refer to the relevant description in the information transmission method 100, which will not be repeated here.

[0229] In summary, in information transmission method 200, the SF network element sends identification information and the first or third information to the SMF network element, which facilitates the SMF network element to send the identification information and QoS requirements for the transmission of sensory data to the access network device. The SF network element also sends the QoS requirements for the sensory service and the identification information to the access network device. This facilitates the access network device to associate the QoS requirements for the sensory service sent by the SF network element with the QoS requirements for the transmission of sensory data sent by the SMF network element based on the identification information. Thus, the access network device can perceive and transmit sensory data based on the QoS requirements for the sensory service and the QoS requirements for the transmission of sensory data, allowing the access network device to perceive and transmit sensory data that meets the requirements of the sensory service. This method can establish sensory services and improve sensory performance.

[0230] Moreover, in the information transmission method 200, the QoS requirements for the perception service are sent to the access network device by the SF network element with the perception function, and the QoS requirements for the transmission of the perception data are sent to the access network device by the SMF network element with the session management function. The QoS requirements for the perception service and the QoS requirements for the transmission of the perception data are transmitted to the access network device separately, and the logical division is clearer.

[0231] In addition, the information transmission method 200 can be applied to scenarios where an access network device performs station-side perception, specifically, scenarios where the access network device autonomously transmits and receives perception signals (i.e., the access network device transmits a perception signal and receives a reflected signal of the perception signal). The access network device can perform station-side perception and report perception data based on the second information and the fourth information.
