Description

Perception method and related device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on October 31, 2023, with application number 202311436599.9 and application name “Perception Methods and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a sensing method and related devices. Background Art

[0003] Wireless communication perception fusion is a key technology for fifth-generation (5G) mobile communications and can be widely applied in typical application scenarios such as smart transportation, smart low-altitude areas, and smart networks. Wireless communication perception fusion achieves unified design of communication and perception functions through joint signal design and hardware sharing. The perception in wireless notification perception fusion can be understood as wireless perception technology based on the communication system. For example, a base station transmits a wireless signal to a target object and receives an echo signal reflected by the target object. The base station analyzes the echo signal to obtain corresponding perception measurements. For example, the number, location, movement speed, and identity of the target objects can be determined.

[0004] Currently, there are two main perception scenarios: per-area and per-object. The following describes the per-area perception scenario. A perception function entity can receive a perception request. The perception request includes area information or location information of the target perception area. The perception function entity can select a corresponding base station, which can then implement the perception process using terminal device-assisted perception.

[0005] For regional awareness services, some scenarios require the participation and assistance of terminal devices, but the network may not have information about terminal devices that can participate in awareness. Therefore, it is worth considering how network devices should enable terminal devices that can provide awareness services within the awareness area to execute the awareness process.

[0118] An embodiment of the present application provides a perception method and related apparatus, for a terminal device to receive a first identifier from a first access network device. If the terminal device supports the first identifier, the terminal device executes a perception process.

[0119] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0120] The term "and / or" as used in this application can be used to describe an association relationship between related objects, indicating that three possible relationships exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0121] Wireless communication perception fusion is a key technology in 5G communications and can be widely applied in typical application scenarios such as smart transportation, smart low-altitude areas, and smart networks. Wireless communication perception fusion achieves unified design of communication and perception functions through joint signal design and hardware sharing. The perception in wireless notification perception fusion can be understood as wireless perception technology based on the communication system. For example, a base station transmits a wireless signal to a target object and receives an echo signal reflected by the target object. The base station analyzes the echo signal to obtain corresponding perception measurements, such as the number, location, movement speed, and identity of target objects.

[0122] Currently, there are two main perception scenarios: area-based and target-based. Area-based perception involves sensing a specific area, such as low-altitude areas in cities, roads, and factories. Typical application scenarios include: locating and detecting drones intruding into regulatory areas at low altitudes in cities, thereby enabling drone intrusion detection in fixed areas; real-time detection of vehicle movement paths and speeds on urban roads to perceive the operating status of highways; sensing channel changes for breathing detection, fitness monitoring, gesture or posture recognition, etc.; and analyzing the relationship between signal attenuation in communication links and weather indicators to obtain corresponding weather indicators and perform weather detection. Target-based perception involves using synaesthesia technology to perceive and track targets with identification, enabling dynamic detection of targets.

[0123] The sensing methods mainly include base station side sensing, terminal device assisted sensing and terminal device side sensing. The following introduces two possible sensing scenarios of terminal device assisted sensing involved in this application in conjunction with Figures 1 and 2.

[0124] Figure 1 illustrates a possible scenario for terminal device-assisted sensing in an embodiment of the present application. As shown in Figure 1 , base station 101 transmits a signal, which is reflected by vehicle 103 to generate a sensing signal. Terminal device 102 receives the sensing signal and measures it to generate a sensing result. Terminal device 102 can report the sensing result to a sensing function entity.

[0125] Figure 2 illustrates another possible scenario for terminal device-assisted sensing in accordance with an embodiment of the present application. As shown in Figure 2 , terminal device 202 transmits a signal, which is reflected by vehicle 203 to produce a sensing signal. Base station 201 receives the sensing signal and measures it to obtain a sensing result. Base station 201 can report the sensing result to the sensing function entity.

[0126] It should be noted that Figures 1 and 2 above are only two examples of terminal device assisted perception scenarios. This application is not limited to terminal device assisted perception scenarios. As long as the terminal device can be triggered to measure the perception signal and report the perception results, and the terminal device can provide assistance to the perception process, it can belong to the terminal device assisted perception scenario mentioned in this application. This application does not make any specific limitations.

[0127] For the perception scenario of terminal device assisted perception, the perception function entity can receive a perception request. The perception request includes the area information or location information of the target perception area. The perception function entity can select a suitable base station and terminal device, and the base station can implement the perception process by using the terminal device assisted perception. For regional perception services in which terminal devices participate, the base station only obtains the area information or location information of the target perception area through the perception request, but does not have the information of the terminal devices that can participate in the perception. Therefore, how the base station should select the terminal device that can provide perception services in the target perception area to implement the perception process is a problem worthy of consideration. The present application provides a corresponding technical solution, which is introduced below in conjunction with specific embodiments.

[0128] FIG3 is a schematic diagram of a communication system according to an embodiment of the present application. Referring to FIG3 , the communication system includes a terminal device 301, a next generation node B (gNB) 302, a next generation evolved node B (ng-eNB) 303, an access and mobility management function (AMF) 304, a user plane function (UPF) 305, and a sensing function (SF) 306.

[0129] The perception function entity 306 shown in Figure 3 is introduced by taking the user plane and control plane separation as an example. In actual applications, the user plane and control plane of the perception function entity may also be inseparable, which is not limited in this application.

[0130] It should be noted that the above-mentioned access and mobility management function entity 304 and user plane function entity 305 are optional, and gNB302 and ng-eNB303 can be connected to the perception function entity 306.

[0131] The terminal device 301 communicates with the access network device (such as gNB302 or ng-eNB303 in Figure 3) through the Uu interface. ng-eNB303 is an access network device in the long term evolution (LTE) communication system, and gNB302 is an access network device in the new radio (NR) communication system. In the communication system, access network devices communicate with each other through the Xn interface, and the access network device and the access and mobility management function entity 304 communicate with each other through the NG-C interface. The access network device communicates with the user plane function entity 305 through the NG-U interface. The user plane function entity 305 is connected to the user plane of the perception function entity 306, and the access and mobility management function entity 304 is connected to the control plane of the perception function entity 306.

[0132] Optionally, the communication system further includes a location management function (LMF), which is a network element, module, or component in the NR core network that provides a positioning function for the terminal device. Optionally, the perception function entity 306 can be co-located with the location management function entity or deployed separately, which is not specifically limited in this application.

[0133] Figure 1 above only illustrates an example of a communication system including two access network devices, namely, a gNB and an ng-eNB. In actual applications, the communication system may include at least one access network device, which is not specifically limited in this application.

[0134] The technical solution of the present application can be applied to cellular communication systems related to the 3rd Generation Partnership Project (3GPP). For example, a fourth generation (4G) communication system, a 5G communication system, and a communication system after the fifth generation communication system. For example, a sixth generation communication system. For example, a fourth generation communication system may include a long term evolution (LTE) communication system. A fifth generation communication system may include a new radio (NR) communication system. The technical solution of the present application can also be applied to a wireless fidelity (WiFi) system, a communication system that supports the integration of multiple wireless technologies, a device-to-device (D2D) system, or a vehicle to everything (V2X) communication system.

[0135] The following introduces the terminal equipment, access network equipment, perception function entity, and core network equipment involved in this application.

[0136] Terminal devices, also known as user equipment (UE), mobile stations (MS), mobile terminals (MT), and customer premise equipment (CPE), are devices that include wireless communication capabilities (providing voice and data connectivity to users). Examples include handheld devices, in-vehicle devices, and machine-type communication (MTC) terminals with wireless connectivity. Currently, terminal devices include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving systems (e.g., drones and vehicles), wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in unmanned driving can be drones, helicopters, or airplanes. For example, wireless terminals in the Internet of Vehicles can be onboard equipment, complete vehicle equipment, onboard modules, vehicles, or ships. Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes.

[0137] It should be noted that the terminal device may also be a chip, module or control unit in the various possible devices or apparatuses shown above, and this application does not limit this specifically.

[0138] Access network equipment (ANE) is a device deployed in a radio access network (RAN) to provide wireless communication capabilities for terminal devices. It connects terminal devices to the radio access network (RAN) nodes of a wireless network. It can also be called AN equipment, RAN entity, access node, network node, or communication device.

[0139] Access network equipment includes, but is not limited to, evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in a wireless fidelity (WIFI) system, wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP), and may also be network equipment in a 5G mobile communication system. For example, a next generation NodeB (gNB), TRP, or transmission point (TP) in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the access network equipment may also be a network node constituting a gNB or a transmission point. For example, a baseband unit (BBU) or a distributed unit (DU).

[0140] In some deployments, a gNB may include a centralized unit (CU) and a DU. The gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, while the DU implements some of the gNB's functions.

[0141] For example, the CU is responsible for processing non-real-time protocols and services, and implementing the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer. The DU is responsible for processing the physical layer protocols and real-time services, and implementing the functions of the radio link control (RLC) layer, the media access control (MAC) layer, and the physical (PHY) layer. The AAU implements some physical layer processing functions, radio frequency processing, and related functions of active antennas. The information of the RRC layer will eventually become the information of the PHY layer, or be converted from the information of the PHY layer. Therefore, under this architecture, high-level signaling (such as RRC layer signaling) can also be considered to be sent by the DU, or by the DU and the AAU.

[0142] It is understood that the access network device may include one or more devices including a CU node, a DU node, and an AAU node. In addition, the CU may be classified as a network device in the access network (RAN) or as a network device in the core network (CN), which is not limited in this application.

[0143] The perception function entity can select appropriate access network devices and terminal devices and send a perception request to the access network devices. This implements the perception process between the access network devices and the terminal devices, thereby achieving perception. In one possible implementation, the perception function entity is deployed together with the positioning management function. In this implementation, the perception function entity also has the function of locating the terminal device. In another possible implementation, the perception function entity and the positioning management function entity are deployed separately. In current or future communication systems, the name of the perception function entity may change as the communication system evolves. Any functional network element with a name similar to the positioning management function entity can be understood as the positioning management function entity of this application. Any functional network element with a name similar to the perception function entity can be understood as the perception function entity of this application and is applicable to the perception method provided in this application. For example, the perception function entity can also be called the communication perception function entity, the positioning management function entity, the first network element, or other names. This application does not specifically limit the name of the perception function entity. The following embodiments primarily use the perception function entity to describe the operations performed by this functional network element.

[0144] The core network equipment can be responsible for access control, registration management, service management, mobility management, etc. of terminal equipment accessing the network. For example, the core network equipment is an access and mobility management functional entity, a perception functional entity, or an application function entity (AF). In this application, the names of the access and mobility management functional entity and the application functional entity may change with the evolution of the communication system. In the current communication system or the future communication system, as long as the functional network element has other names with similar functions to the access and mobility management functional entity, it can be understood as the access and mobility management functional entity of this application and is applicable to the perception method provided in this application. As long as the functional network element has other names with similar functions to the application functional entity, it can be understood as the application functional entity of this application.

[0145] The technical solution of this application is introduced below in conjunction with specific embodiments.

[0146] FIG4 is a schematic diagram of an embodiment of the sensing method of the present application. Referring to FIG4 , the method includes the following steps.

[0147] It should be noted that the embodiment shown in FIG4 uses a terminal device, a first access network device, and a perception function entity as examples of the execution entities of the interaction diagram to illustrate the method, but this application does not limit the execution entities of the interaction diagram. For example, in the embodiment shown in FIG4 , the execution entity in steps 402 to 403 is the terminal device. The execution entity may also be a chip, chip system, or processor that supports the terminal device in implementing the method, or a logic module or software that can implement all or part of the terminal device functions. In the embodiment shown in FIG4 , the execution entity in steps 401, 401a, 401b, and 404 is the perception function entity. The execution entity may also be a chip, chip system, or processor that supports the perception function entity in implementing the method, or a logic module or software that can implement all or part of the perception function entity. In the embodiment shown in FIG4 , the execution entity in steps 401, 402a, 402, and 404 is the first access network device. The execution entity may also be a chip, chip system, or processor that supports the first access network device in implementing the method, or a logic module or software that can implement all or part of the first access network device.

[0148] 401. A perception function entity sends a first perception request to a first access network device. Correspondingly, the first access network device receives the first perception request from the perception function entity.

[0149] The first perception request is used to request the execution of the perception process. Optionally, the first perception request includes a first identifier. The first identifier is used to identify the target perception area and / or to identify the first perception service. For example, the first perception service may be a perception service within an industrial park, a perception service in an indoor place, or vehicle monitoring on a section of road. For another example, the first identifier may identify a perception service in a V2X scenario, and the first identifier may also identify a vehicle speed monitoring perception service in a V2X scenario.

[0150] It should be noted that the name of the first identifier can be an area identifier (area ID), a service identifier (service ID), a sensing service identifier (sensing service ID), a service group identifier (service group ID), or a sensing capability identifier (sensing capability ID). This application does not limit the name of the first identifier.

[0151] Optionally, the first identifier may also identify a first sensing service within the target sensing area. That is, the first identifier is used to identify a specific sensing service within a specific sensing area. For example, this could be speed monitoring on a specific road section, or a speed monitoring sensing service in a specific service scenario. Another example could be monitoring the number of terminals within a cell or an area smaller than a cell.

[0152] It can be seen from this that in this application, the first identifier can be used to identify or distinguish the perception area, and / or to identify or distinguish the perception service.

[0153] In the above step 401, the first access network device is located in the target perception area. Alternatively, the first access network device is included in the target perception area of ​​the requested first perception service.

[0154] Optionally, the first perception request also includes at least one of the following: area information of the target perception area, service information of the target perception area, perception type corresponding to the first perception service, perception time, or perception accuracy requirement. For example, the area information of the target perception area includes at least one of the following: the coordinate range of the target perception area, or a cell list. The location of the target perception area is thereby represented by the cell list. For example, the service information of the target perception area may include the type of service: such as vehicle speed detection under V2X, or load information within the target perception area. The perception service indicated in the service information of the target perception service here can be understood as the first perception service. For example, the requirements for the perception service include perception accuracy and / or perception time requirements for the perception service.

[0155] Optionally, the first perception request also includes an identifier of a perception function entity (SF ID).

[0156] Specifically, the perception function entity determines that the first identifier corresponds to the first access network device, and sends the first perception request to the first access network device.

[0157] In one possible implementation, if the first identifier is used to identify the target perception area and / or to identify the first perception service, the perception function entity determines that the first identifier corresponds to the first access network device based on the third mapping relationship. For details about the third mapping relationship, please refer to the relevant description of step 401a. It should be noted that in step 401 above, the first access network device may include one or more access network devices. That is, the first identifier corresponds to one or more access network devices.

[0158] In another possible implementation, the first perception request includes an identifier of the first access network device. The terminal device determines, based on the first perception request, that the first identifier corresponds to the first access network device. It should be noted that in step 401 above, the first access network device may include one or more access network devices. That is, the first perception request includes the identifiers of the one or more access network devices.

[0159] Optionally, the embodiment shown in FIG4 further includes step 401a. Step 401a may be performed before step 401.

[0160] 401a. The perception function entity determines the first access network device corresponding to the first identifier according to the third mapping relationship.

[0161] The third mapping relationship includes a mapping relationship between at least one identifier and an access network device, where the at least one identifier is an identifier supported by the access network device within at least one sensing area. The access network device within the at least one sensing area may be an access network device managed by an access and mobility management function entity. Each of the at least one identifier corresponds to one or more access network devices. The at least one identifier includes the first identifier. For example, the third mapping relationship may be represented as shown in Table 1:

[0162] Table 1

[0163] For example, the first identifier is identifier 1. As can be seen from Table 1, the first identifier corresponds to access network device 1, that is, the first access network device is access network device 1. For another example, the first identifier is identifier 2. As can be seen from Table 1, the first identifier corresponds to access network device 1 and access network device 2, that is, the first access network device includes access network device 1 and access network device 2.

[0164] Optionally, a possible method for configuring the third mapping relationship for the perception function entity is described below in conjunction with the embodiment shown in Figure 5. This application is still applicable to other methods, and this application does not limit them specifically.

[0165] 501. The core network device or the gateway device sends a third mapping relationship to the perception function entity. Correspondingly, the perception function entity receives the third mapping relationship from the core network device or the gateway device.

[0166] Optionally, the core network device may be an access and mobility management functional entity, or an application functional entity.

[0167] It should be noted that the above step 501 may be performed before step 401 in the embodiment shown in FIG. 4 .

[0168] Optionally, if the first identifier is used to identify the target perception area, but the first identifier is not used to identify the first perception service, the perception function entity further sends service information of the target perception area to the first access network device. That is, service information of the first perception service. Optionally, the service information of the target perception area is included in the first perception request.

[0169] Optionally, if the first identifier is not used to identify the target perception area, but the first identifier is used to identify the first perception service, the perception function entity further sends area information of the target perception area, such as the coordinate range of the target perception area, to the first access network device. Optionally, the area information of the target perception area is carried in the first perception request.

[0170] Optionally, if the first identifier is used to identify a first perception service of the target perception area, the perception function entity may send the first identifier to the first access network device without sending area information and service information of the target perception area.

[0171] Optionally, the embodiment shown in FIG4 further includes step 401b. Step 401b may be performed before step 401.

[0172] 401b. The perception function entity determines a first identifier.

[0173] It should be noted that if the embodiment shown in FIG. 4 includes step 401 a , step 401 b may be performed before step 401 a .

[0174] Two possible implementations of step 401b are described below in conjunction with Figures 6 and 7. This application is still applicable to other implementations, and the following implementations do not limit this application.

[0175] Implementation 1: Optionally, the above step 401 specifically includes step 601 in the embodiment shown in FIG. 6 .

[0176] 601. The perception function entity receives a second perception request.

[0177] The second perception request includes a first identifier. The second perception request is used to request execution of a perception process. Specifically, the perception function entity determines the first identifier based on the second perception request. For details about the first identifier, please refer to the relevant description of step 401 in the embodiment shown in FIG. 4 .

[0178] Optionally, the perception function entity receives a second perception request from a terminal device, an access and mobility management function entity, or an application function entity.

[0179] Optionally, the second perception request further includes at least one of the following: area information of the target perception area, service information of the target perception area, or perception service requirements. For the content included in the second perception request, please refer to the relevant introduction of the content included in the first perception request, which will not be repeated here.

[0180] Implementation method 2: Optionally, the above step 401 specifically includes step 701 and step 702 in the embodiment shown in FIG. 7 .

[0181] 701. A sensing function entity receives a third sensing request, wherein the third sensing request includes area information of a target sensing area and / or service information of the target sensing area.

[0182] The third perception request is used to request the execution of the perception process. For example, the area information of the target perception area includes at least one of the following: the coordinate range of the target perception area, or a cell list. The location of the target perception area is thus represented by the cell list. For example, the service information of the target perception area may include: vehicle speed detection under V2X, or load information within the target perception area. The perception service indicated in the service information of the target perception service here can be understood as the first perception service in the aforementioned step 401.

[0183] Optionally, the perception function entity receives a third perception request from a terminal device, an access and mobility management function entity, or an application function entity.

[0184] Optionally, the third perception request further includes a perception service requirement. The perception service requirement includes at least one of the following: a perception time requirement or a perception accuracy requirement of the perception service.

[0185] 702. The perception function entity determines the first identifier according to the second mapping relationship.

[0186] In one possible implementation, the third perception request includes area information of the target perception area, and the second mapping relationship includes a mapping relationship between area information of at least one perception area and at least one identifier. The at least one identifier is an identifier supported by an access network device within the at least one perception area. For example, the second mapping relationship can be represented as shown in Table 2:

[0187] Table 2

[0188] For example, the area information of the target perception area includes area information 1. Therefore, it can be seen from Table 2 above that area information 1 corresponds to identification 1, that is, the first identification is identification 1.

[0189] In another possible implementation, the third perception request includes service information of the target perception area, and the second mapping relationship includes a mapping relationship between at least one service information and at least one identifier. The at least one identifier is an identifier supported by the access network device within the at least one perception area. For example, the second mapping relationship can be represented as shown in Table 3:

[0190] Table 3

[0191] For example, the service information of the target perception area includes service information 1. Therefore, it can be seen from Table 3 above that service information 1 corresponds to identifier 1, that is, the first identifier is identifier 1.

[0192] In another possible implementation, the third perception request includes area information of the target perception area and service information of the target perception area.

[0193] The second mapping relationship includes a mapping relationship between the area information of at least one perception area and at least one service information and at least one identifier. The at least one identifier is an identifier supported by the access network device within the at least one perception area. Each identifier in the at least one identifier is used to identify a specific perception area and a specific perception service, or in other words, each identifier is used to represent a specific perception service within a specific regional perception. For example, the second mapping relationship can be expressed as shown in Table 4:

[0194] Table 4

[0195] For example, the area information of the target perception area includes area information 1, and the business information of the target perception area includes business information 1. Therefore, it can be seen from Table 4 above that area information 1 and business information 1 both correspond to identifier 1, that is, the first identifier is identifier 1.

[0196] Optionally, the embodiment shown in FIG7 further includes step 702a. Step 702a may be performed before step 702.

[0197] 702a. The perception function entity receives the second mapping relationship.

[0198] Optionally, the awareness function entity receives a second mapping relationship from an access and mobility management function or a gateway device.

[0199] Specifically, the access and mobility management function entity or the gateway device determines a second mapping relationship and sends the second mapping relationship to the perception function entity.

[0200] 402. The first access network device sends a first identifier to the terminal device. Correspondingly, the terminal device receives the first identifier from the first access network device.

[0201] Among them, the terminal device is located in the target sensing area.

[0202] Optionally, the first access network device sends the first identifier to the terminal device via a paging message, a system message, or an RRC message. Correspondingly, the terminal device receives the first identifier from the first access network device via a paging message, a system message, or an RRC message.

[0203] For example, if the terminal device is in an RRC connected state, the first access network device may send a first identifier to the terminal device via an RRC message.

[0204] For example, the first access network device may send the first identifier to the terminal device via a paging message.

[0205] For example, the first access network device broadcasts the first identifier through a system message.

[0206] Optionally, if the first identifier is used to identify the target perception area, but is not used to identify the first perception service, the first access network device further sends service information of the target perception area to the terminal device, that is, service information of the first perception service.

[0207] Optionally, if the first identifier is not used to identify the target perception area, but is used to identify the first perception service, the first access network device also sends area information of the target perception area to the terminal device, such as the coordinate range of the target perception area.

[0208] Optionally, if the first identifier is used to identify the first perception service of the target perception area, the first access network device may send the first identifier to the terminal device without sending the area information and service information of the target perception area.

[0209] When the first identifier is used to identify the target perception area, the first access network device determines the target perception area corresponding to the first identifier. The first access network device sends the first identifier to a terminal device located in the target perception area. Specifically, the first access network device may select a corresponding cell and / or a corresponding beam. Then, the first access network device sends the first identifier to the terminal device located in the target perception area in the cell via the beam.

[0210] Optionally, the embodiment shown in FIG4 further includes step 402a. Step 402a may be performed before step 402.

[0211] 402a. The first access network device determines a target perception area corresponding to the first identifier according to the first mapping relationship.

[0212] It should be noted that the first access network device includes one or more access network devices. The following description takes the example of the first access network device including one access network device. In the case of multiple access network devices, each access network device determines the target perception area corresponding to the first identifier based on the first mapping relationship preconfigured in the access network device.

[0213] Among them, the first mapping relationship includes a mapping relationship between at least one identifier supported by the first access network device and the perception area information. Each identifier in the at least one identifier is used to identify a specific perception area. The first identifier belongs to the at least one identifier. Each identifier supported by the first access network device means that the first access network device supports the implementation of the perception process in the specific perception area identified by the identifier through terminal device assisted perception. For example, the first mapping relationship can be expressed as shown in Table 5:

[0214] Table 5

[0215] For example, as shown in Table 5, the first identifier is identifier 1. As can be seen from Table 5, identifier 1 corresponds to perception area information 1. The perception area information 1 includes area information of the target perception area.

[0216] Optionally, a possible method for configuring the first mapping relationship for the first access network device is described below in conjunction with the embodiment shown in Figure 8. This application is still applicable to other methods, and this application does not limit them specifically.

[0217] 801. A core network device or a gateway device sends a first mapping relationship to a first access network device. Correspondingly, the first access network device receives the first mapping relationship from the core network device or the gateway device.

[0218] Optionally, the core network device is a perception functional entity or an access and mobility management functional entity.

[0219] It should be noted that step 801 can be executed before step 402a. There is no fixed execution order between step 801 and step 401. Step 801 can be executed first, and then step 401; or, step 401 can be executed first, and then step 801; or, step 801 and step 401 can be executed simultaneously depending on the situation, and this application does not limit this. If the embodiment shown in Figure 4 also includes steps 401a to 401b, there is no fixed execution order between step 801 and steps 401a to 401b. Step 801 can be executed first, and then steps 401a to 401b; or, steps 401a to 401b can be executed first, and then step 801; or, steps 401a to 401b and step 801 can be executed simultaneously depending on the situation, and this application does not limit this.

[0220] 403. If the terminal device supports the first identifier, the terminal device executes the perception process.

[0221] The terminal device determines at least one identifier supported by the terminal device. Optionally, each identifier in the at least one identifier supported by the terminal device is used to identify a specific perception area, and / or each identifier is used to identify a specific perception service.

[0222] Each identifier is used to identify a specific perception area, and each identifier supported by the terminal device can be understood as the terminal device supporting the execution of the perception process within the perception area identified by the identifier. Alternatively, each identifier is used to identify a specific perception service, and each identifier supported by the terminal device can be understood as the terminal device supporting the execution of the perception process corresponding to the perception service identified by the identifier. Alternatively, each identifier is used to identify a specific perception service within a specific perception area. Each identifier supported by the terminal device can be understood as the terminal device supporting the execution of the perception process corresponding to the perception service identified by the identifier within the perception area identified by the identifier.

[0223] Therefore, the terminal device supporting the first identifier may specifically mean that the terminal device supports executing the perception process within the target perception area identified by the first identifier, or that the terminal device supports executing the perception process corresponding to the first perception service identified by the first identifier, or that the terminal device supports executing the perception process corresponding to the first perception service within the target perception area identified by the first identifier.

[0224] Specifically, if the first identifier belongs to at least one identifier supported by the terminal device, the terminal device executes the perception process. If the first identifier does not belong to at least one identifier supported by the terminal device, the terminal device ignores the first identifier. For example, the terminal device receives a paging message from a first access network device. The paging message includes the first identifier. If the terminal device supports the first identifier, the terminal device can initiate random access to access the network, and then execute the perception process. If the terminal device does not support the first identifier, the terminal device may not initiate random access, but ignore the paging message. It can be seen from this that the technical solution of the present application, when performing perception of the target perception area, the first access network device can trigger the appropriate terminal device to participate in perception according to the first identifier, thereby realizing the execution of the perception process.

[0225] Optionally, the first identifier is used to identify the target perception area instead of identifying the first perception service. If the terminal device supports the first identifier, the terminal device executes the perception process, and the terminal device is located in the target perception area.

[0226] Optionally, the first identifier is used to identify the first perception service instead of the target perception area. If the terminal device supports the first identifier, the terminal device executes the perception process corresponding to the first perception service. The terminal device may be located in the target perception area or not. Optionally, if the first perception request received by the first access network device includes the area information of the target perception area, the first access network device sends the first identifier to the target perception area. If the terminal device supports the first identifier and is in the target perception area, the terminal device executes the perception process.

[0227] In one possible implementation, the terminal device executes a perception process, including: the terminal device receives a perception signal, which is obtained by reflecting a signal emitted by a first access network device through a target in a target perception area; the terminal device measures the perception signal to obtain a perception result; the terminal device sends a perception report to the first access network device, the access and mobility management function entity, the perception function entity or the positioning management function entity, and the perception report includes the perception result and a first identifier. Optionally, the perception report also includes area information of the target perception area, and / or service information of the target perception area (i.e., service information of the first perception service). For example, if the first identifier is used to identify the target perception area but not for identifying the first perception service, then the perception message may also include service information of the first perception service. For another example, if the first identifier is used to identify the first perception service but not for identifying the target perception area, then the perception message may also include area information of the target perception area.

[0228] In another possible implementation, the terminal device executes a perception process, including: the terminal device transmits a signal within the target perception area, the signal is reflected by the target in the target perception area to obtain a perception signal; the first access network device measures the perception signal to obtain a perception result. The first access network device can send a perception report to the access and mobility management function entity, the perception function entity or the positioning management function entity, and the perception report includes the perception result and the first identifier. Optionally, the perception report also includes area information of the target perception area, and / or, service information of the target perception area (i.e., service information of the first perception service). For example, if the first identifier is used to identify the target perception area but not for identifying the first perception service, then the perception message can also include service information of the first perception service. For another example, if the first identifier is used to identify the first perception service but not for identifying the target perception area, then the perception message can also include area information of the target perception area.

[0229] Optionally, a possible implementation method of configuring at least one identifier supported by the terminal device for the terminal device is described below in conjunction with the embodiment shown in Figure 9. This application is still applicable to other implementation methods, and this application does not make specific limitations.

[0230] 901. A core network device sends at least one identifier supported by the terminal device to a terminal device. Correspondingly, the terminal device receives the at least one identifier from the core network device.

[0231] In a possible implementation, the core network device is a unified data management function entity, and the terminal device receives at least one identifier supported by the terminal device from the unified data management function entity via the access and mobility management function entity.

[0232] Specifically, the at least one identifier supported by the terminal device may be stored in the unified data management function entity when the terminal device signs a contract. When the terminal device initiates registration, the access and mobility management function entity may read the at least one identifier supported by the terminal device from the unified data management function entity and send the at least one identifier supported by the terminal device to the terminal device.

[0233] In another possible implementation, the core network device is a perception function entity, and the terminal device receives at least one identifier supported by the terminal device from the perception function entity.

[0234] Specifically, the perception function entity may determine at least one identifier supported by the terminal device according to the service requirements and the perception capability information of the terminal device, and then send the at least one identifier supported by the terminal device to the terminal device.

[0235] It should be noted that step 901 can be executed before step 403 in the embodiment shown in Figure 4. It should be noted that there is no fixed execution order between step 901 and steps 401 to 402 in the embodiment shown in Figure 4. For example, step 901 can be executed first, and then steps 401 to 402; or, steps 401 to 402 can be executed first, and then step 901; or, depending on the situation, step 901 and steps 401 to 402 can be executed simultaneously, and this application does not limit this.

[0236] Optionally, the embodiment shown in FIG9 further includes step 901a. Step 901a may be performed before step 901.

[0237] 901a: The terminal device sends sensing capability information to the core network device. Correspondingly, the core network device receives the sensing capability information from the terminal device.

The first access network device may send a first perception response to the perception function entity, and the first perception response is used to indicate that the perception process is successfully executed. Optionally, the first perception response includes a first identifier. Optionally, the first perception response also includes a perception result. Optionally, the first perception response also includes area information of the target perception area, and / or, service information of the target perception area (i.e., service information of the first perception service). For example, if the first identifier is used to identify the target perception area but not for identifying the first perception service, then the first perception response may also include service information of the first perception service. For another example, if the first identifier is used to identify the first perception service but not for identifying the target perception area, then the first perception response may also include area information of the target perception area.

[0243] In another possible implementation, as described in the above step 403, the first access network device measures the perception signal to obtain a perception result. The first access network device sends a first perception response to the perception function entity, and the first perception response is used to indicate that the perception process is successfully executed. Optionally, the first perception response includes a first identifier. Optionally, the first perception response also includes a perception result. Optionally, the first perception response also includes area information of the target perception area, and / or service information of the target perception area (i.e., service information of the first perception service). For example, if the first identifier is used to identify the target perception area but not to identify the first perception service, then the first perception response may also include service information of the first perception service. For another example, if the first identifier is used to identify the first perception service but not to identify the target perception area, then the first perception response may also include area information of the target perception area.

[0244] Optionally, after the above-mentioned step 404, as shown in Figure 6, in step 602, the first access network device sends a second perception response. The second perception response is used to indicate whether the perception process is successfully executed. Optionally, the first access network device sends the second perception response to the terminal device, the access and mobility management function entity, or the application function entity. For example, the first perception response is used to indicate that the perception process is successfully executed, and the second perception response is used to indicate that the perception process is successfully executed. Optionally, the second perception response includes a first identifier. Optionally, the second perception response also includes area information of the target perception area, and / or, service information of the target perception area (i.e., service information of the first perception service). For example, if the first identifier is used to identify the target perception area but not for identifying the first perception service, then the second perception response may also include service information of the first perception service. For another example, if the first identifier is used to identify the first perception service but not for identifying the target perception area, then the second perception response may also include area information of the target perception area.

[0245] Optionally, after the above step 404, as shown in Figure 7, in step 703, the first access network device sends a third perception response. The third perception response is used to indicate whether the perception process is successfully executed. Optionally, the first access network device sends a third perception response to the terminal device, the access and mobility management function entity, or the application function entity.

If the terminal device supports the first identifier, the terminal device executes a perception process, and the terminal device is located in the target perception area. Thus, the terminal device determines whether it supports the first identifier. If the terminal device supports the first identifier, the terminal device executes a perception process, and the terminal device is located in the target perception area. This enables the first access network device to select the terminal device to provide a perception function entity to implement the perception process.

[0247] FIG10 is a schematic diagram of another embodiment of the sensing method according to an embodiment of the present application. Referring to FIG10 , the method includes:

[0248] It should be noted that, in the embodiment shown in FIG10 , the terminal device, the first access network device, and the perception function entity are used as examples of the execution subjects of the interaction diagram to illustrate the method, but the present application does not limit the execution subjects of the interaction diagram. For example, in the embodiment shown in FIG10 , the execution subject in steps 1001c to 1001d, step 1002, and step 1003 is the terminal device, and the execution subject may also be a chip, chip system, or processor that supports the terminal device to implement the method, or a logic module or software that can implement all or part of the terminal device functions. In the embodiment shown in FIG10 , the execution subject in steps 1001a, 1001b, 1001d, 1001, and 1004 is the perception function entity, and the execution subject may also be a chip, chip system, or processor that supports the perception function entity to implement the method, or a logic module or software that can implement all or part of the perception function entity. In the embodiment shown in Figure 10, the execution subject in steps 1001c, 1001, 1002 and 1004 is the first access network device. The execution subject can also be a chip, chip system or processor that supports the first access network device to implement the method, or a logic module or software that can implement all or part of the first access network device.

[0249] 1001. A perception function entity sends a first perception request to a first access network device. The first perception request includes a first identifier and an identifier of a terminal device. Accordingly, the first access network device receives the first perception request from the perception function entity.

[0250] Specifically, the perception function entity determines that the first identifier corresponds to the first access network device. The perception function entity determines that the terminal device supports the first identifier. Therefore, the first perception request may include the first identifier and the identifier of the terminal device. This enables the perception function entity to indicate to the first access network device that the terminal device can assist the first access network device in implementing the perception process. The perception function entity selects an appropriate terminal device to provide the perception service. Optionally, the perception function entity may be determined using the first set in step 1001d below. Please refer to the relevant description below for details.

[0251] Step 1001 is similar to step 401 in the embodiment shown in FIG. 4 . For details, please refer to step 401 in the embodiment shown in FIG. 4 .

[0252] Optionally, the embodiment shown in FIG10 further includes step 1001a. Step 1001a can be performed before step 1001.

[0253] 1001a. The perception function entity determines the first access network device corresponding to the first identifier according to the third mapping relationship.

[0254] Step 1001a is similar to step 401a in the embodiment shown in FIG. 4 . For details, please refer to the relevant introduction of step 401a in the embodiment shown in FIG. 4 , which will not be repeated here.

[0255] Optionally, the embodiment shown in FIG10 further includes step 1001b. Step 1001b may be performed before step 1001.

[0256] 1001b. The perception function entity determines the first identifier.

[0257] Step 1001b is similar to step 401b in the embodiment shown in FIG. 4 . For details, please refer to the relevant introduction of step 401b in the embodiment shown in FIG. 4 .

[0260] 1001c. The first access network device sends at least one identifier supported by the first access network device to the terminal device. Correspondingly, the terminal device receives the at least one identifier from the first access network device.

[0261] The identifier supported by the first access network device indicates that the first access network device needs to perform the perception service within the perception area corresponding to the identifier, or perform the perception service corresponding to the identifier within the coverage area of ​​the first access network device, or perform the corresponding perception service within the perception area corresponding to the identifier.

[0262] Optionally, the first access network device sends at least one identifier supported by the first access network device via a broadcast message.

[0263] 1001d. The terminal device sends a first set to the perception function entity. The first set includes at least one identifier supported by both the first access network device and the terminal device. Correspondingly, the perception function entity receives the first set from the terminal device.

[0264] In other words, the first set includes at least one identifier supported by the terminal device from the at least one identifier sent by the first access network device. Therefore, if the first identifier belongs to the first set, the perception function entity can determine that the terminal device supports the first identifier. Therefore, the first perception request in step 401 can include the identifier of the terminal device, thereby enabling the perception function entity to instruct the first access network device to select the terminal device and implement the perception process with the assistance of the terminal device.

[0265] It should be noted that in step 1001d, the terminal device reports at least one identifier supported by both the first access network device and the terminal device in the form of a first set. In practical applications, the first set may also be represented by a first list or other forms, which is not specifically limited in this application.

[0266] Steps 1001c and 1001d above illustrate a possible implementation. In practical applications, the terminal device may report at least one identifier supported by the terminal device to the perception function entity, which then determines the first set. Alternatively, the terminal device may report at least one identifier supported by the terminal device to the first access network device or the access and mobility management function entity; the first access network device or the access and mobility management function entity may send the at least one identifier supported by the terminal device to the perception function entity, which then determines the first set.

[0267] 1002. The first access network device sends a first identifier to the terminal device. Correspondingly, the terminal device receives the first identifier from the first access network device.

[0268] Optionally, the first access network device sends the first identifier to the terminal device via an RRC message. Correspondingly, the terminal device receives the first identifier from the first access network device via an RRC message.

[0269] Step 1002 is similar to step 402 in the embodiment shown in FIG. 4 . For details, please refer to the relevant introduction of step 402 in the embodiment shown in FIG. 4 .

[0270] 1003. If the terminal device supports the first identifier, the terminal device executes the perception process.

[0271] Step 1003 is similar to step 403 in the embodiment shown in Figure 4 above. For details, please refer to the relevant introduction of step 403 in the embodiment shown in Figure 4 above. It can be seen that the technical solution of the present application can trigger the appropriate terminal device to participate in the perception according to the first identifier when perceiving the target perception area, thereby realizing the execution of the perception process.

[0272] Optionally, the embodiment shown in FIG10 further includes step 1004. Step 1004 may be performed after step 1003.

[0273] 1004. The first access network device sends a first perception response to the perception function entity. Correspondingly, the perception function entity receives the first perception response from the first access network device.

[0274] Step 1004 is similar to step 404 in the embodiment shown in FIG. 4 . For details, please refer to the relevant introduction of step 404 in the embodiment shown in FIG. 4 .

[0275] In this embodiment of the present application, a terminal device receives a first identifier from a first access network device. The first identifier is used for a target perception area. If the terminal device supports the first identifier, the terminal device executes a perception process, and the terminal device is located in the target perception area. Thus, the terminal device determines whether it supports the first identifier. If the terminal device supports the first identifier, the terminal device executes a perception process, and the terminal device is located in the target perception area. This enables the first access network device to select the terminal device to provide perception services to implement the perception process.
