[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the China Patent Office on September 13, 2023, with application number 202311183472.0 and invention name “Communication Perception Method, Device and Computer-Readable Storage Medium”. The entire contents of the Chinese patent application are incorporated herein by reference. Technical Field

[0003] This specification relates to the technical field of communication perception integration, and more specifically to a communication perception method, device, and computer-readable storage medium. Background Art

[0004] With the development of 5G-A and 6G mobile networks, base stations will be able to perceive the state of targets within their coverage areas, and mobile terminals will be upgraded to intelligent entities with perceptual capabilities. For example, base stations will be able to sense low-flying objects, traffic flow, and crowds of people in hotspots; detect, locate, identify, and track key targets; and measure the natural environment and weather conditions in the coverage area in real time. At close range, mobile terminals can recognize a person's posture, movements, and expressions; and at micro-range, they can identify the attributes of targets within the human body, products, and objects.

[0005] In future wireless networks, communication and perception capabilities will merge and coexist, evolving towards the technology direction of "communication and perception integration." This will empower wireless networks with the ability to perceive the physical world at all times and everywhere. This will fully satisfy the need for multi-dimensional sensory integration and effectively support the wide-area expansion of communication capabilities, opening up application space beyond traditional mobile communication network connections.

[0006] Based on the perception area to be performed, it can be divided into two categories: static perception area and dynamic perception area. Static perception area refers to the area that needs to be perceived in advance, such as the perception of foreign object intrusion in a specific area of ​​a high-speed railway, the perception of unmanned aerial vehicle intrusion in a specific airspace, and the detection of rainfall in a certain area. Dynamic perception area refers to the area that needs to be perceived, which changes at any time. For example, when perceiving the flight trajectory of an unmanned aerial vehicle, since the position of the unmanned aerial vehicle changes dynamically during flight, the perception area also changes dynamically. Assisted driving and / or autonomous driving vehicles use the communication perception function provided by the operator to assist the vehicle during driving, and the perception area also changes dynamically.

[0007] At present, facing the construction of integrated communication and perception networks in dynamic perception areas, the industry mainly focuses on the solutions and implementation of network-side perception capabilities, and the end-to-end perception process is still unclear.

[0008] Summary of the Invention

[0011] In a second aspect, a communication perception system is provided, including: a perception control unit SCU, used to receive a perception service request initiated by a perception demand party, wherein the perception demand party includes a target object STO with perception needs or a service initiator AF to which the STO belongs; determining a target perception execution unit SEU that meets the perception service request based on the current location information of the STO, and issuing a perception instruction to the target SEU, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the SCU; receiving the perception data returned by the target SEU, and sending the perception data to the perception demand party.

[0012] According to a third aspect, an electronic device is provided, comprising: a processor; and a memory for storing instructions executable by the processor; wherein the processor is configured to execute the instructions to implement the method described in the first aspect.

[0028] To help those skilled in the art better understand the technical solutions in this specification, the following will provide a clear and complete description of the technical solutions in the embodiments of this specification, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this specification, not all of them. All other embodiments derived by those skilled in the art based on the embodiments in this specification without creative effort shall fall within the scope of protection of this specification.

[0029] It should be understood that the technical solutions of the embodiments of this specification can be applied to various communication systems, such as: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS) or Worldwide Interoperability for Microwave Access (WiMAX) communication system, 5G system, or New Radio (NR) system.

[0030] User Equipment (UE), also known as a mobile terminal, can communicate with at least one core network via a radio access network (e.g., Radio Access Network, RAN). The terminal equipment can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges voice and / or data with the radio access network.

[0031] A network device (or network-side device) is a device deployed in a wireless access network to provide communication perception functions. The network device can be a base station, which can be a base station (Base Transceiver Station, BTS) in GSM or CDMA, or a base station (NodeB) in WCDMA, or an evolved base station (eNB or e-NodeB) in LTE and a 5G base station (gNB), as well as network devices in subsequent evolved communication systems. However, the wording does not constitute a limitation on the scope of protection of this specification.

[0032] It should be noted that when describing specific embodiments, the size of the serial number of each process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this specification.

[0033] When it comes to building integrated sensing and communication (ISAC) networks in dynamic sensing areas, the industry is primarily focused on the solution and implementation of network-side sensing capabilities. The end-to-end sensing process, the specific distribution of sensing capabilities across mobile network entities, and the transmission of large-scale sensing data remain unclear. For example, will the 5G-A core network supporting communication sensing capabilities overlay communication sensing capabilities on the existing Location Management Function (LMF) or Access and Mobility Management Function (AMF), or will it add a new Sensing Function (SF)? There is currently no clear plan for how sensing capabilities will be distributed across relevant network elements. Research on 6G communication sensing systems has yet to begin.

[0034] In order to solve at least one of the above problems, this specification proposes a communication perception system and a communication perception method. The following first introduces a communication perception system provided in this specification.

[0035] As shown in Figure 1, in one embodiment, a communication perception system provided in this specification may include: a perception demand party, a perception control unit (Sensing Control Unit, SCU) 12 and a perception execution unit (Sensing Execution Unit, SEU) 13, wherein the perception demand party includes a target object (Sensing Target Object, STO) 102 with perception requirements or an application function (AF) 101 to which the STO belongs.

[0036] SCU 12 can be used to receive a perception service request initiated by a perception demand party, wherein the perception demand party includes a target object STO 102 with a perception demand or a service initiator AF 101 to which the STO belongs; determine the target perception execution unit SEU 13 that meets the perception service request based on the current location information of the STO 102, and issue a perception instruction to the target SEU 13, wherein the target SEU 13 is used to perform a perception operation according to the perception instruction to obtain perception result data, and send the perception result data to the SCU 12; receive the perception result data returned by the target SEU 13, and send the perception result data to the perception demand party.

[0037] Among them, STO 102 can be an unmanned aerial vehicle, an automatic driving / assisted driving vehicle, etc. STO 102 has a mobile network identifier and is a user of the mobile communication network.

[0038] Optionally, the SCU 12 may also be configured to generate a perception detail record SDR and transmit the SDR to an operator's billing center so that the operator's billing center performs billing.

[0039] Optionally, the SCU 12 may be further configured to, before determining a target SEU that meets the service awareness request based on the current location information of the STO, determine a sensing mode for the service awareness request after receiving the service awareness request. Specifically, the target SEU that meets the service awareness request may be determined based on the current location information of the STO and the sensing mode.

[0040] Specifically, the SCU 12 may determine the perception mode for the service perception request in one of the following ways:

[0041] If the sensing service request carries a sensing mode, the SCU uses the sensing mode carried in the sensing service request as the sensing mode for the service sensing request;

[0042] If the perception service request does not carry a perception mode, the SCU determines whether the perception demander is configured with a default perception mode, and if so, uses the default perception mode as the perception mode for the service perception request;

[0043] If the perception service request does not carry a perception mode, and the perception demander has not configured a default perception mode, the SCU independently determines the perception mode for the service perception request.

[0044] The sensing mode includes one of the following:

[0045] Network equipment sends and receives data on its own;

[0046] The terminal equipment sends and receives data by itself;

[0047] The first network device sends and the second network device receives;

[0048] The first terminal device sends and the second terminal device receives;

[0049] The network device sends and the terminal device receives;

[0050] The terminal device sends and the network device receives.

[0051] Optionally, SCU 12 can also be used to receive a perception capability registration request initiated by the target SEU before determining the target perception execution unit SEU that meets the perception service request based on the current location information of the STO, and return a perception capability registration response to the target SEU; wherein the perception capability registration request is used to register the perception capability it possesses in the SCU.

[0052] Optionally, SCU 12 can also be used to determine whether it is necessary to authenticate the perception demander before determining the target perception execution unit SEU that meets the perception service request based on the current location information of the STO; if it is necessary to authenticate the perception demander, authenticate the perception demander, and if the authentication of the perception demander is passed.

[0053] Specifically, SCU 12 can be used for authentication in the following ways: determining whether the perception demand party belongs to the designated AF; if the perception demand party belongs to the designated AF, determining that the perception demand party does not need to be authenticated; if the perception demand party does not belong to the designated AF, determining that the perception demand party needs to be authenticated.

[0054] Optionally, SCU 12 can also be used to determine the payment category of the perception demand party for obtaining the perception service before determining the target perception execution unit SEU that meets the perception service request based on the current location information of the STO, if the perception demand party is authenticated; if the payment category is prepaid, the SCU determines whether the balance of the perception demand party is sufficient to pay the fees required for this perception service, and if the balance is sufficient to pay the fees required for this perception service, the target SEU is determined based on the current location information of the STO and the perception service request.

[0055] If the perception demander is the STO, the perception service request is initiated by the STO via a user plane connection or a control plane network attached storage NAS message.

[0056] The STO belongs to one or more AFs; or the STO does not belong to any AF.

[0057] In one example, as shown in FIG2 , the SCU 12 may include a Home Sensing Control Unit (HSCU) 121 and a Visit Sensing Control Unit (VSCU) 122. The HSCU 121 and the VSCU 122 may be located in the same network element or in different network elements. The HSCU 121 and the VSCU 122 may be the same functional module or different functional modules. When the HSCU 121 and the VSCU 122 are the same functional module, they may be collectively referred to as the SCU, and no distinction between the HSCU 121 and the VSCU 122 is made.

[0058] When the SCU 12 includes an HSCU 121 and a VSCU 122, and the HSCU 121 and the VSCU 122 belong to different functional modules, the HSCU 121 is used to receive a perception service request initiated by a perception demander; obtain the VSCU 122 where the STO is currently located, and forward the perception service request to the VSCU 122; the VSCU 122 is used to determine the target SEU 13 that meets the perception service request based on the current location information of the STO 102, wherein the target SEU 13 is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the VSCU.

[0059] Among them, the VSCU122 can be specifically used to: generate a dynamic perception area identifier based on the location information of the cell where the STO is currently located; and determine one or more SEUs in the perception area where the dynamic perception area identifier is located as the target SEU 13 based on the registered SEUs with perception capabilities and the parameter information carried in the perception service request.

[0060] The current location information of the STO is obtained by the VSCU from the STO; or, the current location information of the STO is carried in the perception service request.

[0061] Among them, when the data volume of the perception data exceeds the preset data volume, that is, when the perception data is large-packet perception data, the target SEU can send the perception data to the SCU via the data bus, which can increase the transmission speed of the perception data and improve the satisfaction of the perception demander with the perception service.

[0062] When the SCU 12 includes the HSCU 121 and the VSCU 122, and the HSCU 121 and the VSCU 122 belong to different functional modules, the VSCU 122 is used to receive the perception data returned by the target SEU and send the perception data to the HSCU 121; the HSCU 121 is used to send the perception data to the perception demander.

[0063] The SCU 12 may be a network element or a collection of multiple network elements. The specific distribution of the SCU 12 in the network elements is described below using two examples.

[0064] As a first example, in a 5G-A network, the SCU 12 may include, but is not limited to, one or more of the following network elements:

[0065] 1) Network Exposure Function (NEF);

[0066] 2) Location Management Function (LMF);

[0067] 3) Gateway Mobile Location Center (GMLC);

[0068] 4) Sensing Function (SF);

[0069] 5) Access and Mobility Management Function (AMF);

[0070] 6) Unified Data Management (UDM).

[0071] The second example, as shown in Figure 3 (Figure 3 is a schematic diagram of the distribution of perception capabilities provided by an embodiment of this specification in network entities under the 6G architecture), in the 6G network, the SCU may include but is not limited to multiple services distributed in the Network Control Unit (NCU) 34.

[0072] In Figure 2, SEU 13 may include, but is not limited to, base stations and / or terminal devices with sensing capabilities. Specifically, as shown in Figure 3, in a 6G network, SEUs with sensing execution capabilities may include, but are not limited to, at least one of a radio access network control plane (RAN-CP) 35, a radio access network user plane (RAN-UP) 36, and a terminal 38. In Figure 3, STO 102 may still be an autonomous or assisted driving vehicle.

[0073] In addition, in Figure 3, NIU stands for Network Intelligent Unit, NDU stands for Network Data Unit, and NPU stands for Network Packet Unit. The functions of these three network elements belong to the existing technology and will not be described in detail herein.

[0074] In this way, the specific distribution of perception capabilities in mobile network entities in the construction of an integrated communication and perception network for dynamic perception areas can be clarified.

[0075] The above is a brief introduction to the architecture of a communication perception system provided in this specification.

[0076] The communication perception system and communication perception method provided in the embodiments of this specification can be applied to any perception scenario oriented towards a dynamic perception area, including but not limited to:

[0077] 1) Trajectory tracking of unmanned aerial vehicle flight (a type of STO)

[0078] Under normal circumstances, unmanned aerial vehicles (UAVs) fly along predetermined routes, adhering to preset positions, altitudes, speeds, and directions. However, in certain circumstances, such as under the influence of strong sunlight, rain, snow, or other inclement weather, the UAV's sensors may malfunction, making it impossible for the UAV to follow its predetermined route. This could result in the UAV being lost.

[0079] A communication perception system or a communication perception method provided in the embodiments of this specification can use base stations with ubiquitous coverage or UEs with perception capabilities to track the flight trajectory of unmanned aerial vehicles in real time, and provide unmanned aerial vehicle flight trajectory tracking services to trusted third-party applications (for example, unmanned aerial vehicle service operators, unmanned aerial vehicle management departments) to avoid the loss of unmanned aerial vehicles.

[0080] 2) Navigation and collision avoidance of unmanned aerial vehicles (a type of STO)

[0081] Unmanned aerial vehicles (UASs) can provide their movement information and surrounding dynamic environment information perceived by their sensors to the Uncrewed Aerial System Traffic Management (UTM). The UTM then controls the UAS's flight trajectory accordingly to avoid collisions with other UASs or obstacles. However, the sensing range of a single UAS is limited. During flight, it may not be able to detect the surrounding environment in a timely manner, which can cause the UAS to deviate from its original route or even cause a collision.

[0082] The embodiments of this specification provide a communication perception system or a communication perception method, which can perform perception through widely distributed base stations or UEs with perception capabilities, collect perception information of the flight environment of unmanned aerial vehicles, such as taller buildings, obstacles, and other unmanned aerial vehicles nearby, and provide continuous sensing services during the flight of the unmanned aerial vehicle, dynamically plan flight routes, navigate the unmanned aerial vehicle, and prevent collisions with obstacles or other unmanned aerial vehicles.

[0083] 3) Assisted Driving / Autonomous Driving

[0084] To support assisted and autonomous driving, vehicles are equipped with a variety of sensors, such as cameras, radar, and LiDAR. However, when there's a vehicle ahead, the vehicle's own sensors can't detect the road conditions blocking the vehicle, making automated overtaking dangerous. Mobile base stations and sensing UEs in the network provide real-time perception of the road ahead, feeding this information into the vehicle's autonomous driving system. This assists in overtaking decisions and ensures safe driving.

[0085] Another scenario involves a vehicle traveling at normal speed on a main road. If a pedestrian, vehicle, or other object suddenly emerges from a side road not controlled by traffic lights (commonly known as a "ghost peeking"), the vehicle's sensors may not be able to effectively detect it. Using the mobile network's communication and perception capabilities, base stations and sensing terminals can effectively input this side road perception information into the vehicle's autonomous driving system. This allows the driver to obtain this information in advance, ensuring the safety of both the vehicle and pedestrians.

[0086] The above are merely examples of dynamic perception areas provided by a communication perception system or a communication perception method provided in the embodiments of this specification, and are not limited to these dynamic perception areas.

[0087] The following is a detailed description of a communication perception method provided in this specification. By understanding this method, the end-to-end perception process in scenarios facing dynamic perception areas can be clearly understood.

[0088] As shown in FIG4 , in one embodiment, a communication perception method provided in this specification may include the following steps:

[0089] Step 401: The sensing control unit SCU receives a sensing service request initiated by a sensing demander, wherein the sensing demander includes a target object STO having sensing demand or a service initiator AF to which the STO belongs.

[0090] The STO may belong to one or more AFs, or the STO may not belong to any AF. In the case where the STO belongs to one or more AFs, the perception demand party may be either the one or more AFs or the STO itself; in the case where the STO does not belong to any AF, the perception demand party is the STO itself, or the AF is the STO itself. In the case where the perception demand party is the STO, the perception service request may be initiated by the STO through a user plane connection or a control plane network attached storage non-access stratum (NAS) message.

[0091] Among them, the perception service request comes from the perception demand party (AF or STO), and the perception service request usually carries the mobile network identifier of the STO. In addition, the perception service request may also carry one or more of the following parameters: perception service type, perception mode, perception base station identifier or UE identifier, perception recognition accuracy, perception recognition false alarm rate, perception distance, perception area, perception speed range, perception distance resolution, perception angle measurement accuracy, perception speed resolution, perception service quality (Quality of Service, QoS) requirements, perception data update frequency, perception feedback method, perception service requester type, perception service requester identifier, perception application (AF) identifier, etc.

[0092] In one example, the SCU may include an HSCU and a VSCU, where the HSCU and the VSCU may belong to the same functional module or different functional modules. If the HSCU and the VSCU belong to the same functional module, the HSCU and the VSCU are actually the SCU. If the HSCU and the VSCU do not belong to the same functional module, step 401 may specifically include: the HSCU receiving a perception service request initiated by a perception demander.

[0093] In step 402, the SCU determines the target perception execution unit SEU that meets the perception service request based on the current location information of the STO, and issues a perception instruction to the target SEU, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the SCU.

[0094] Optionally, before step 402, the method shown in FIG4 may further include: the SCU receiving a sensing capability registration request initiated by the target SEU, wherein the sensing capability registration request is used to register its sensing capability with the SCU; and the SCU returning a sensing capability registration response to the target SEU. Through this step, the SCU can know whether the target SEU has the corresponding sensing capability and thus decide whether to issue the corresponding sensing instruction to the target SEU.

[0095] In a first example, when the SCU includes an HSCU and a VSCU, and the HSCU and the VSCU belong to different functional modules, step 402 may include:

[0096] After receiving the sensing service request, the HSCU obtains the service sensing control unit VSCU where the STO is currently located, and forwards the sensing service request to the VSCU;

[0097] The VSCU determines a target perception execution unit SEU that meets the perception service request based on the current location information of the STO, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the VSCU.

[0098] Among them, obtaining the service perception control unit VSCU where the STO is currently located may include: obtaining the VSCU where the STO is currently located from the subscriber data management network element (Subscriber Data Management, SDM) of the STO home location.

[0099] Among them, the current location information of the STO may include but is not limited to Global Navigation Satellite System (GNSS) location information, such as longitude and latitude, and / or location information of the mobile network where the STO is located, such as CELLID, etc. Taking the current location information of the STO as an example, which may include the location information of the cell where the STO is currently located (such as CELLID), the VSCU determines the target perception execution unit SEU that meets the perception service request based on the current location information of the STO, which may include: the VSCU generates a dynamic perception area identifier (Mobile Area Identification, MAreaID) based on the location information of the cell where the STO is currently located; the VSCU determines one or more SEUs in the perception area (Area Identification, AreaID) where the dynamic perception area identifier MAreaID is located as the target SEU based on the registered SEUs with perception capabilities and the parameter information carried in the perception service request. For example, assuming the perception area is "Xinjiekou", the perception area identifier can be "025001"; MArealID can be an area identifier that can be recognized by the mobile communication network, for example, a set of one or more CELLIDs, or a set of one or more base station IDs, etc.

[0100] In a second example, when the SCU includes an HSCU and a VSCU, but the HSCU and the VSCU belong to the same functional module, step 402 may include:

[0101] After receiving the perception service request, the SCU uses the current location information of the STO to determine the target perception execution unit SEU that meets the perception service request, wherein the target SEU is used to perform perception operations according to the perception instructions to obtain perception data and send the perception data to the SCU.

[0102] Taking the example that the current location information of the STO may include the location information of the cell where the STO is currently located (such as CELLID), the SCU determines the target perception execution unit SEU that meets the perception service request based on the current location information of the STO, which may include: the SCU generates a dynamic perception area identifier (Mobile Area Identificaiton, MAreaID) based on the location information of the cell where the STO is currently located; the SCU determines one or more SEUs in the perception area (Area Identificaiton, AreaID) where the dynamic perception area identifier MAreaID is located as the target SEU based on the registered SEUs with perception capabilities and the parameter information carried in the perception service request.

[0103] In the above two examples, the current location information of the STO can be obtained by the VSCU from the STO, that is, the VSCU obtains the location information of the STO by interacting with the STO; or the current location information of the STO is included in the sensing service request. It should be noted that there are many ways to obtain the current location information of the STO, and this specification does not limit this.

[0104] Among them, after receiving the perception instruction, the target SEU can perform specific perception operations according to the content of the perception instruction and the carried perception parameters, such as QoS, and return the perception data to the SCU; further, in order to reduce the network transmission data traffic, the perception data returned by the target SEU to the SCU can be the original perception measurement data of the target SEU, the perception measurement data processed by the target SEU, or the final perception result processed by the target SEU.

[0105] Optionally, when the amount of the perception data exceeds the preset data amount, that is, when the perception data is large-packet perception data, the target SEU can send the perception data to the SCU via the data bus, which can increase the transmission speed of the perception data and improve the satisfaction of the perception demander with the perception service.

[0106] Step 403: The SCU receives the sensing data returned by the target SEU, and sends the sensing data to the sensing demander.

[0107] Optionally, when the SCU includes an HSCU and a VSCU, and the HSCU and the VSCU belong to different functional modules, step 403 may include: the VSCU receives the perception data returned by the target SEU, and sends the perception data to the HSCU; the HSCU sends the perception data to the perception demander.

[0108] The HSCU may send the perception data to the perception demand party through its own capability exposure interface, or may send the perception data to the perception demand party through a control plane NAS message.

[0109] A communication perception method provided in an embodiment of this specification can be used by a perception control unit SCU to receive a perception service request initiated by a perception demander, wherein the perception demander includes a target object STO with a perception demand or a service initiator AF to which the STO belongs; the SCU determines a target perception execution unit SEU that meets the perception service request based on the current location information of the STO, and issues a perception instruction to the target SEU, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the SCU; the SCU receives the perception data returned by the target SEU, and sends the perception data to the perception demander. In this way, the end-to-end perception process in the construction of a communication perception integrated network for dynamic perception areas can be clarified.

[0110] Optionally, as shown in FIG5 , in another embodiment, the communication perception method provided in this specification may further include, after step 403:

[0111] In step 404, the SCU generates a Sensing Detail Record (SDR) and transmits the SDR to the operator's billing center so that the operator's billing center performs billing.

[0112] In actual applications, the SCU may transmit the SDR to the operator's billing center immediately or periodically. Specifically, if the SCU includes an HSCU and a VSCU, and the HSCU and the VSCU belong to different functional modules, step 404 may include: the HSCU generates an SDR and transmits the SDR to the operator's billing center for billing and settlement.

[0113] In this way, the billing and settlement process of perception services can be further clarified.

[0114] Optionally, in a communication perception method provided in this specification, the SCU may also have one of the following functions: perception capability discovery function, perception mode determination function, AF request area and mobile network identifiable area conversion function, permission management function for one or more AFs, and service management function. Some of these functions are described in detail below.

[0115] Optionally, as shown in FIG6 , in another embodiment, the perception communication method provided in this specification may further include, after step 401 and before step 402:

[0116] Step 405: The SCU determines a sensing mode for the service sensing request.

[0117] Specifically, in the case that the SCU includes an HSCU and a VSCU, and the HSCU and the VSCU belong to different functional modules, step 405 may include: the HSCU determines a perception mode for the service perception request.

[0118] Accordingly, step 402 may include: the SCU determines a target perception execution unit SEU that meets the perception service request based on the current location information of the STO and the perception mode. Similarly, when the SCU includes an HSCU and a VSCU, and the HSCU and the VSCU belong to different functional modules, step 405 may include: after receiving the perception service request, the HSCU obtains the service perception control unit VSCU where the STO is currently located, and forwards the perception service request to the VSCU; the VSCU determines a target perception execution unit SEU that meets the perception service request based on the current location information of the STO and the perception mode, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the VSCU.

[0119] Determining the perception mode for the service perception request may include at least one of the following methods:

[0120] 1) If the sensing service request carries a sensing mode, the SCU uses the sensing mode carried in the sensing service request as the sensing mode for the service sensing request;

[0121] 2) If the perception service request does not carry a perception mode, the SCU determines whether the perception demander is configured with a default perception mode, and if so, uses the default perception mode as the perception mode for the service perception request;

[0122] 3) If the perception service request does not carry a perception mode, and the perception demander has not configured a default perception mode, the SCU independently determines the perception mode for the service perception request.

[0123] The sensing mode may include but is not limited to the following:

[0124] Network equipment sends and receives data on its own;

[0125] The terminal equipment sends and receives data by itself;

[0126] The first network device sends and the second network device receives;

[0127] The first terminal device sends and the second terminal device receives;

[0128] The network device sends and the terminal device receives;

[0129] The terminal device sends and the network device receives.

[0130] It can be understood that first determining the perception mode for the business perception request, and then determining the target perception execution unit SEU that meets the perception business request based on the current location information of the STO and the perception mode, can make the determined target SEU more in line with the needs of the perception demander.

[0131] Optionally, as shown in FIG7 , in another embodiment, the perception communication method provided in this specification may further include, before step 402:

[0132] In step 406 , the SCU determines whether it is necessary to authenticate the perceived demander; if so, execute step 407 ; otherwise, execute step 402 or execute step 408 .

[0133] Exemplarily, the SCU may set up a whitelist that does not require authentication, which includes some designated SFs, and then determine whether the perception demand party belongs to the designated AF; when the perception demand party belongs to the designated AF, the SCU determines that the perception demand party does not need to be authenticated; when the perception demand party does not belong to the designated AF, the SCU determines that the perception demand party needs to be authenticated.

[0134] In step 407, the SCU authenticates the perceived demander and determines whether the authentication is successful; if successful, execute step 408 or step 402; if not, execute step 410, or execute step 410 after returning an appropriate response to the perceived demander.

[0135] In step 408 , the SCU determines whether the payment type for the perception demander to obtain the perception service is prepaid; if so, execute step 409 ; otherwise, execute step 402 .

[0136] In step 409, the SCU determines whether the balance of the perception demander is sufficient to pay for the cost of this perception service; if so, execute step 402; otherwise, execute step 410, or execute step 410 after returning an appropriate response to the perception demander.

[0137] Step 402: Determine a target sensing execution unit SEU based on the current location information of the STO and the sensing service request.

[0138] Step 403: The SCU receives the sensing data returned by the target SEU, and sends the sensing data to the sensing demander.

[0139] Step 410, end.

[0140] It is understandable that by setting up authentication, payment category judgment and other links, the perception business process can be further improved and clarified.

[0141] The following is a more detailed description of a communication perception method provided in the specification through an interactive flow diagram.

[0142] As shown in FIG8 , a communication perception method provided in this specification may be applied to a perception communication system including a perception demand party (AF / STO) 10, an HSCU 121, a VSCU 122, an SDM 15, and a SEU 13. The method may include:

[0143] In step 801 , the sensing demander (AF / STO) 10 initiates a sensing service request to the HSCU 121 .

[0144] Among them, the perception service request carries the mobile network identifier of the STO. In addition, the perception service request may also carry one or more of the following parameters: perception service type, perception mode, perception base station identifier or UE identifier, perception recognition accuracy, perception recognition false alarm rate, perception distance, perception area, perception speed range, perception distance resolution, perception angle measurement accuracy, perception speed resolution, perception service quality (QoS) requirements, perception data update frequency, perception feedback method, perception service requester type, perception service requester identifier, perception application (AF) identifier, etc.

[0145] In step 802, the HSCU 121 performs authentication and billing category determination on the AF, and determines the sensing mode.

[0146] Specifically, as shown in FIG10 , in step 802 , the HSCU 121 determines the sensing mode, which may include:

[0147] In step 8021 , the HSCU 121 determines whether the sensing service request carries a sensing mode; if so, execute step 8022 ; otherwise, execute step 8023 .

[0148] In step 8022, the HSCU 121 adopts the sensing mode in the sensing service request.

[0149] In step 8023, the HSCU 121 determines whether the AF is configured with a default sensing mode; if so, step 8024 is executed; otherwise, step 8025 is executed.

[0150] In step 8024, the HSCU 121 adopts the default sensing mode of the AF.

[0151] In step 8025, the HSCU 121 determines the sensing mode on its own.

[0152] Specifically, as shown in FIG11 , in step 802 , the HSCU 121 performs authentication and billing category determination on the AF, which may include:

[0153] In step 8026, the HSCU 121 determines whether the AF needs to be authenticated; if so, execute step 8027; if not, execute step 8028 or execute step 803.

[0154] In step 8027, the HSCU 121 determines whether the authentication for the AF is successful; if so, execute step 8028; if not, execute step 817.

[0155] In step 8028, the HSCU 121 determines whether the payment type of the AF is prepaid; if so, execute step 8029; if not, execute step 803.

[0156] In step 8029 , the HSCU 121 determines whether the balance of the AF is sufficient to pay for the fee required for this sensing service; if so, execute step 803 ; if not, execute step 817 .

[0157] Step 803: The HSCU 121 obtains the VSCU where the STO is currently located.

[0158] HSCU 121 may initiate a request to the STO home subscriber data management network element SDM 15 (e.g., the UDM network element of a 5G network or the network control unit NCU of a 6G network) to obtain the VSCU where the STO is currently located.

[0159] In step 804 , the HSCU 121 sends the sensing service request to the VSCU 122 .

[0160] In step 805, the VSCU 122 obtains the current location information of the STO and generates a dynamic sensing area identifier MArealID according to the current location information of the STO.

[0161] The current location information of the STO includes but is not limited to Global Navigation Satellite System (GNSS) location information, such as longitude and latitude, and / or location information of the mobile network where the STO is located, such as CELLID.

[0162] As an example, the VSCU 122 may obtain the current location information of the STO by interacting with the STO. When the VSCU 122 obtains the current location information of the STO, if the STO is in an idle state, the VSCU 122 may first establish a connection with the STO.

[0163] As another example, if the perception service request carries the current location information of the STO, it is directly obtained from the perception service request.

[0164] In step 806 , the VSCU 122 determines one or more SEUs in the area where the MArealD is located as target SEUs 13 .

[0165] Specifically, the VSCU 122 may select one or more SEUs with corresponding sensing capabilities as the target SEU 13 according to the VSCU 122 , the sensing mode, and the parameters carried in the sensing service request.

[0166] In step 807 , the VSCU 122 sends a sensing instruction to the target SEU 13 .

[0167] In step 808 , the target SEU 13 performs a sensing operation in response to the sensing instruction to obtain sensing data.

[0168] In step 809 , the target SEU 13 returns the sensed data to the VSCU 122 .

[0169] The target SEU 13 can return the perception data to the VSCU 122 immediately or periodically (when a specified period is reached). Furthermore, in the case where the perception data is large packet data, the target SEU 13 can return the perception data to the VSCU 122 via a data bus, which can be a control plane bus (Service Based Interface, SBI) or a data plane bus (Data Channel Interface, DCI). Among them, SBI is the protocol adopted by the 5G and 5G-A core networks. It is based on the HTTP / 2 protocol and has a size limit for data transmission; DCI is mainly used for the transmission of batch data, solving the efficient transmission of large blocks of data such as databases, files, blocks, objects, and data streams that is difficult to achieve with SBI.

[0170] In step 810, if necessary, the VSCU 122 performs secondary processing on the received sensing data to form a final sensing result and generate a sensing detail record (SDR).

[0171] In step 811 , the VSCU 122 sends the sensing data or the secondary processed sensing result to the HSCU 121 via a sensing service response.

[0172] In step 812, the HSCU 121 generates a sensory detail record (SDR).

[0173] In step 813 , the HSCU 121 sends the sensing data or the secondary processed sensing result to the sensing demander (AF / STO) 10 via a sensing service response.

[0174] Specifically, the HSCU 121 may send the perception data or the secondary processed perception results to the perception demander (AF / STO) 10 via the perception capability open interface or the control plane NAS message.

[0175] In step 814 (optional), the target SEU 13 directly sends the sensing data or the secondary processed sensing result to the sensing demand party (AF / STO) 10 through the sensing service response. For example, the target SEU 13 directly sends the sensing data or the secondary processed sensing result to the sensing demand party (AF / STO) 10 through the DCI channel.

[0176] Step 810 and step 812 are optional. Specifically, it can be determined according to the operator's policy whether one of the HSCU 121 and the VSCU 122 generates the perception detail data record (SDR).

[0177] In step 817 , the HSCU 121 returns an appropriate response to the sensing demand party (AF / STO) 10 , and then proceeds to step 818 .

[0178] Optionally, the HSCU 121 and the VSCU 122 may belong to the same functional module. In this case, the interaction steps between the HSCU 121 and the VSCU 122 in FIG. 8 may be omitted.

[0179] Step 818, end.

[0180] Optionally, before step 802, steps 815 and 816 may also be performed.

[0181] In step 815 , the SEU 13 initiates a sensing capability registration request to the SCU 12 (specifically, the HSCU 121 in FIG. 8 ).

[0182] In step 816 , SCU 12 returns a sensing capability registration response to SEU 13 .

[0183] Specifically, if the registration is successful, a registration success response is returned in the perception capability registration response; if the registration fails, an appropriate error reason is returned in the perception capability registration response.

[0184] A communication perception method provided in an embodiment of this specification can be used by a perception control unit SCU to receive a perception service request initiated by a perception demander, wherein the perception demander includes a target object STO with a perception demand or a service initiator AF to which the STO belongs; the SCU determines a target perception execution unit SEU that meets the perception service request based on the current location information of the STO, and issues a perception instruction to the target SEU, wherein the target SEU is used to perform a perception operation according to the perception instruction to obtain perception data, and send the perception data to the SCU; the SCU receives the perception data returned by the target SEU, and sends the perception data to the perception demander. In this way, the end-to-end perception process in the construction of an integrated communication perception network facing a dynamic perception area can be clarified.

[0185] In addition, in a communication perception method provided in an embodiment of the present specification, when the data volume of the perception data exceeds the preset data volume, that is, when the perception data is large-packet perception data, the target SEU can send the perception data to the SCU via a data bus (such as SBI or DCI), which can increase the transmission speed of the perception data and improve the satisfaction of the perception demander with the perception service.

[0186] Furthermore, in a communication perception method provided in an embodiment of this specification, SCU 12 may be a network element or a collection of multiple network elements. Specifically, in a 5G-A network, SCU 12 may include but is not limited to one or more of NEF, LMF, GMLC, SF, AMF and UDM; in a 6G network, SCU may include but is not limited to multiple services distributed in NCU; SEU 13 may include but is not limited to base stations and / or terminal devices with perception capabilities. For example, in a 6G network, SEUs with perception execution capabilities may include but are not limited to at least one of RAN-CP, RAN-UP and terminals. This can clarify the distribution of perception capabilities in mobile network entities in the construction of an integrated communication perception network for dynamic perception areas.

[0187] The above introduces the communication perception method applied to the terminal device. The following describes the structure of the terminal device and the network device provided in this specification.
