Description

Sensing method and sensing device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 30, 2023, with application number 202311637605.7 and application name “Perception Method and Perception Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of perception, and more specifically, to a perception method and a perception device. Background Art

[0003] The 3rd Generation Partnership Project (3GPP) has proposed the functions and requirements for sensing communication services. The purpose of wireless sensing technology is to obtain characteristic information about remote objects or environments without physical contact with them. Wireless sensing refers to the ability to use radio frequency signals to obtain information about the characteristics of the environment and / or objects in it (such as shape, size, direction, speed, position, distance, or relative motion between objects). Sensing data is derived from wireless signals affected by target objects or environmental influences (such as reflection, refraction, and diffraction). Wireless sensing can be applied to applications such as intruder / interrupter detection (on roads, railways, drone-restricted areas, yards, and homes), monitoring applications (for rainfall, tourism, flooding, breathing, and movement), navigation assistance applications, real-time map generation applications, and collision avoidance applications. For example, a drone-restricted area monitoring application can use a sensing base station with wireless sensing characteristics to enable sensing within the restricted area. By analyzing sensing data such as reflection, refraction, and diffraction of radio frequency signals, it can detect whether a drone has intruded.

[0004] Currently, there is no relevant solution to manage perception targets and perception time, so how to manage perception targets and perception time is an urgent problem to be solved. Summary of the Invention

[0005] The embodiments of the present application provide a perception method and a perception device, which can manage perception time and / or perception targets.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0115] Figure 6 is an example of a perception method provided by an embodiment of the present application. The method is illustrated by taking the interaction between the first management node and the second management node as an example. Of course, the subject that executes the action of the first management node in the method can also be a device / module in the first management node, such as a chip, processor, processing unit, etc. in the first management node; the subject that executes the action of the second management node in the method can also be a device / module in the second management node, such as a chip, processor, processing unit, etc. in the second management node, and the embodiment of the present application does not make specific limitations on this. The processing performed by a single execution subject (for example, the first management node or the second management node) in the embodiment of the present application can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. Exemplarily, as shown in Figure 6, method 600 includes:

[0116] S610: The second management node sends a sensing request to the first management node. Correspondingly, the first management node receives the sensing request from the second management node.

[0117] Optionally, in an embodiment of the present application, the first management node configures an access network device that perceives the first service based on the perception request, wherein the access network device that perceives the first service includes at least one access network device.

[0118] Exemplarily, the first service is used to configure access network equipment within a specific area to perform perception, or the first service is used to configure access network equipment to perform perception on a specific perception target, or the first service is other services, which is not limited in the embodiments of the present application.

[0119] In an embodiment of the present application, the perception request includes at least one of the following: perception time information, or an identifier of the perception target.

[0120] The perception time information includes at least one of the following: a start time and an end time for perceiving the first service, or a perception period for the first service. By including the perception time information in the perception request, the first management node can manage the perception period of the first service, or support scheduled perception of the first service.

[0121] Exemplarily, the time when the second management node sends the perception request to the first management node is 10:30, and the start time and end time for perceiving the first service included in the perception request are 11:30 and 11:45 respectively, then the access network device will perceive the first service from 11:30 to 11:45. In other words, the access network device starts perceiving the first service at 11:30 and ends perceiving the first service at 11:45. Alternatively, exemplarily, the perception request includes a perception period of 30 minutes for the first service, then the access network device performs perception of the first service every 30 minutes, for example, the access network device perceives the first service in the first 15 minutes of every 30 minutes.

[0122] Optionally, the identification of the perception target in the embodiment of the present application is the identification of one perception target; or, the identification of the perception target in the embodiment of the present application is the identification of each of multiple perception targets, that is, the identification of each perception target in the multiple perception targets, for example, the identification of multiple perception targets is a list of identifications of perception targets, or a set of identifications of perception targets, which is not limited in the embodiment of the present application.

[0123] Optionally, the identification of the perceived target is a unique identification registered with the perceived target. For example, if the perceived target is an unmanned aerial vehicle (UVA), the identification of the perceived target is the unique identification registered with the UVA. Optionally, if the perceived target is a pedestrian or an animal, the identification of the perceived target is used to identify the pedestrian or animal. Optionally, if the perceived target is another object, the identification of the perceived target is used to identify the other object.

[0124] Optionally, the identifier of the sensing target is a unique identifier of the sensing target allocated by the second management node.

[0125] Optionally, the identifier of the perception target is the identifier of the perception target assigned by the first management node, that is, the identifier of the perception target under the first management node. Optionally, the second management node determines the unique identifier of the perception target based on the identifier assigned by the first management node to the perception target. In one possible implementation, the second management node adds the identifier prefix of the first management node to the identifier assigned by the first management node to the perception target to determine the unique identifier of the perception target; in another possible implementation, the second management node maps the identifier assigned by the first management node to the perception target to the unique identifier of the perception target under the second management node.

[0126] Optionally, the identifier of the perception target is the identifier assigned by the access network device to the perception target, which is the identifier of the perception target under the access network device. Optionally, the first management node determines the identifier of the perception target under the first management node based on the identifier assigned by the access network device to the perception target. In one possible implementation, the first management node adds the identifier prefix of the access network device to the identifier assigned by the access network device to the perception target, and determines the identifier of the perception target at the first management node; in another possible implementation, the first management node maps the identifier assigned by the access network device to the perception target to the identifier of the perception target under the first management node. Further, optionally, the second management node determines the unique identifier of the perception target based on the identifier of the perception target determined by the first management node at the first management node. For details, please refer to the description in the above embodiment and will not be repeated here.

[0127] For example, the identification of the perception target in the access network device may be #1, the identification in the first management node may be &1 or, and the identification in the second management node may be *1 or *, which is not limited in the embodiment of the present application.

[0128] It should be noted that, in a possible implementation, the identifier of the perception target is allocated by the access network device to the perception target, and the first management node obtains the identifier of the perception target allocated by the access network device by obtaining a perception report.

[0129] Optionally, in an embodiment of the present application, the first management node configures an access network device for sensing the first service based on the perception request, wherein the access network device is at least one access network device.

[0130] S620: The first management node sends a perception report to the second management node. Correspondingly, the second management node receives the perception report from the first management node.

[0131] In an embodiment of the present application, the perception report includes at least one of the following: perception target type information, perception target location information, perception target trajectory information, perception target speed information, perception target moving direction information, and perception target identification. In an embodiment of the present application, the perception report includes the type of the perception target, which can enable the receiver of the perception report (for example, the first management node, the second management node) to determine the type of the target perceived by the access network device; the perception report includes at least one of the position of the perception target, the trajectory of the perception target, the speed of the perception target, and the moving direction of the perception target, which can enable the receiver of the perception report (for example, the first management node, the second management node) to determine the moving state of the target perceived by the access network device; the perception report includes the identification of the perception target, which can enable the receiver of the perception report (for example, the first management node, the second management node) to use the identification of the perception target to identify the unique target in the entire domain or area, and further, to achieve tracking of the perception target.

[0132] Exemplarily, the perception target type information is used to indicate the type of the perception target, and the type of the perception target may include, for example, pedestrians, animals, UAVs, etc.

[0133] Exemplarily, the perception target location information includes an identifier of the cell where the perception target is located, an identifier of the access network device corresponding to the perception target, an identifier of the tracking area corresponding to the perception target, and / or one or more of the geographical longitude, latitude, and altitude corresponding to the perception target.

[0134] Exemplarily, the perception target trajectory information includes the motion trajectory of the perception target. Exemplarily, the motion trajectory of the perception target includes the identifier of the cell where the perception target is located, the identifier of the access network device corresponding to the perception target, the tracking area identifier corresponding to the perception target, and / or one or more of the geographical longitude, latitude, and altitude corresponding to the perception target. For example, the perception target is a UAV, and the perception target trajectory is the flight path of the UAV; for another example, the perception target is a pedestrian or an animal, and the perception target trajectory is the movement path of the pedestrian or animal. Exemplarily, the perception target speed information includes one or more of the X-axis speed, Y-axis speed, and Z-axis speed corresponding to the perception target, wherein the X-axis, Y-axis, and Z-axis are three-dimensional coordinates in the geodetic coordinate system.

[0135] Exemplarily, the perceived target movement direction information includes the perceived target movement direction, and the perceived target movement direction may include the direction in which the perceived target moves east, south, west, or north. For example, the perceived target moves 30m south, or the perceived target moves 30m north, or the perceived target moves 30m northeast, etc. The embodiments of the present application do not limit this.

[0136] In one possible implementation, the first management node sending the perception report to the second management node includes: the first management node sending the perception report to the second management node in response to the perception request. In other words, after receiving the perception request, the first management node triggers the sending of the perception report to the second management node.

[0137] The following describes the sensing method provided in the embodiment of the present application in detail in three scenarios:

[0138] Scenario 1: Perception of a specific area.

[0139] In this scenario, exemplarily, the perception request in step S610 is perception request one, and perception request one includes perception time information. Exemplarily, perception request one is a regional perception request, that is, perception request one is used to request perception of a specific area (for example, the first area) within the perception time corresponding to the perception time information, and the first service is used to configure the access network equipment in the first area to perform perception at the perception time corresponding to the perception time information. It should be noted that the first management node configures at least one access network device for perceiving the first area according to perception request one, and the at least one access network device perceives the first area within the perception time corresponding to the perception time information. For example, the access network devices covering the first area (or the service scope of the access network device is the first area) are base stations 1 to base stations 10, then base stations 1 to base stations 10 perceive the first area within the perception time corresponding to the perception time information, and obtain perception data corresponding to the first area.

[0140] Correspondingly, perception request one also includes at least one of the following: first area information, first area type information, perception target type information, perception number information, or service level agreement (SLA) indicator information.

[0141] Exemplarily, the first area information is used to indicate the area information to be sensed, which may be a cell identifier list (such as a physical cell identifier (PCI), a cell identifier (ID), etc.), a base station identifier list (gNB ID), a tracking area identity list (TAI), and / or geographical latitude and longitude area information.

[0142] Exemplarily, the first area type information is used to indicate the type corresponding to the first area, and the area type may include, for example, ground, low altitude, water area, etc.

[0143] Exemplarily, the perception target type information is used to indicate the type of the perception target, and the perception target type may include, for example, pedestrians, animals, UAVs, etc.

[0144] Exemplarily, the perception number information is used to indicate the maximum or minimum number of targets to be perceived, including the number of perception targets perceived by performing one perception on the first area.

[0145] Exemplarily, the SLA indicator information is used to indicate that the perception report carries an SLA indicator obtained after perceiving the first area, or the SLA indicator information is used to indicate a threshold value of the SLA indicator for perceiving the first area. The SLA indicator includes one or more of the following: confidence level, positioning estimation accuracy, velocity estimation accuracy, perception resolution, maximum perception service latency, refresh rate, missed detection rate, and false detection rate. The following describes the parameters in the SLA indicator information.

[0146] The confidence level describes the degree of authenticity of the sensing data measured by the access network equipment used for sensing, expressed as a percentage. For example, the confidence level can be set to 95% in the sensing request, and the credibility of the sensing data is 95%.

[0147] Positioning estimation accuracy describes the degree of closeness between the position of the sensing target obtained by the access network device used for sensing by executing the sensing request and its actual position value.

[0148] The speed estimation accuracy describes how close the speed of the perceived target, obtained by the access network device through the sensing request, is to its actual speed. The speed estimation accuracy can be calculated based on the change in the perceived position of the object.

[0149] Perception resolution describes the minimum difference between the measured value and the true value of different types of perception targets that can be detected. For example, the perception resolution for detecting the presence of a drone can be 10 meters at range and 10 meters / second at speed. The perception resolution for tracking a flying drone can be 1 meter at range and 1 meter / second at speed.

[0150] The maximum perception service latency describes the maximum delay from the second management node sending a perception request to the first management node reporting a perception report. Alternatively, it describes the maximum delay from the first management node configuring an access network device for perception to the access network device reporting a perception report. This is not limited in the present embodiments.

[0151] The refresh rate describes the rate at which the access network device used for perception generates perception data. For example, if perception data is generated once every second, the resolution is the inverse of the time interval, that is, 0.1.

[0152] The missed detection rate describes the ratio of unperceived sensing targets or events to all sensing targets or events in any predetermined period during which the access network device used for sensing attempts to obtain sensing data.

[0153] The false detection rate describes the ratio of non-sensing targets or events to all sensing targets or events sensed during any predetermined period when the access network equipment used for sensing attempts to obtain sensing data.

[0154] Accordingly, in this scenario, the perception report in step S620 is, illustratively, perception report 1, which includes at least one of the following: perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target movement direction information. For examples of perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target movement direction information, refer to the description of the above embodiment and are not repeated here.

[0155] In scenario one, perception report one is obtained by perceiving the first area, that is, a perception report for regional perception. For example, if perception request one includes perception target type information, and the type of the perception target included in the perception target type information is UVA, then perception report one is a perception report corresponding to one or more UVAs perceived by the access network device for perceiving and discovering the first area. Optionally, the perception report includes an identifier of the perception target, which is used to determine one or more of the type information, location information, trajectory information, speed information, and movement direction information corresponding to the perception target perceived and discovered in the first area.

[0156] Scenario 2: Perceiving a specific perception target.

[0157] In this scenario, exemplarily, the perception request in step S610 is perception request 2, and perception request 2 includes the identifier of the perception target. Exemplarily, perception request 2 is a tracking perception request, that is, perception request 2 is used to request perception of the perception target corresponding to the identifier of the perception target. For example, if the perception target is moving, the perception target is tracked and perceived. It should be noted that the first management node configures at least one access network device to perceive the perception target corresponding to the identifier of the perception target according to perception request 2, and the at least one access network device perceives the perception target corresponding to the identifier of the perception target. For example, the first management node estimates the second area to the tenth area (i.e., the route of the perception target) to which the perception target may move based on the movement trajectory of the perception target. The access network devices covering the second area to the tenth area are base stations 6 to base stations 14, respectively. Base stations 6 to base stations 14 perceive the perception targets corresponding to the identifiers of the perception targets in turn, and obtain the perception data of each base station perceiving the perception targets corresponding to the identifiers of the perception targets, that is, the perception target corresponding to the identifier of the perception target moves to the second area, and base station 6 perceives the perception target corresponding to the identifier of the perception target and obtains the perception data. The perception target corresponding to the identifier of the perception target moves to the third area, and base station 7 perceives the perception target corresponding to the identifier of the perception target and obtains the perception data. This is deduced from the above and will not be repeated here.

[0158] Accordingly, in this scenario, the perception report in step S620 is, illustratively, perception report 2, which includes at least one of the following: perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target movement direction information. For examples of perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target movement direction information, please refer to the description of the above embodiment and will not be repeated here.

[0159] In scenario 2, perception report 2 is obtained by perceiving the perception target corresponding to the perception target identifier, i.e., a perception report of tracking perception. The aforementioned perception target type information, perception target position information, perception target trajectory information, perception target speed information, and perception target movement direction information are the perception target type information, position information, trajectory information, speed information, and movement direction information corresponding to the corresponding perception target identifier.

[0160] For example, the identification of the perception target included in perception request 2 is identification list 1 of the perception target, identification list 1 of the perception target is shown in Table 1, and perception report 2 is shown in Table 2, where #1 represents the identification of perception target 1, #2 represents the identification of perception target 2, and #3 represents the identification of perception target 3.

[0161] Table 1

[0162] Table 2 takes perception report 2 including perception target type information, perception target position information, perception target trajectory information, perception target speed information, and perception target moving direction information as an example. Perception report 2 includes the perception report of the perception target corresponding to the identifier of each perception target in perception target identification list 1.

[0163] Table 2

[0164] Optionally, the second management node filters the perception targets from the perception targets corresponding to the identifiers of the perception targets included in the perception request 2 according to the perception report 2. For example, the second management node determines to further perceive the perception targets 1 and 2 based on the perception reports corresponding to the perception targets 1, 2, and 3 shown in Table 2. The second management node then sends a perception request to the first management node again, and the perception request includes #1 and #2.

[0165] Scenario 3: includes two perceptions. The first perception: perception of a specific area, and the perception report 3 includes the identification of the perception target; the second perception: perception of a specific perception target.

[0166] This scenario includes the process of sensing a specific area in the above scenario 1 and the process of sensing a specific sensing target in the above scenario 2. In other words, this scenario includes the sending and receiving processes of the sensing request in step S610 and the sensing report in step S620 twice. For example, as shown in FIG7 , the method 700 includes:

[0167] S710: The second management node sends a first perception request to the first management node. Correspondingly, the first management node receives the first perception request from the second management node.

[0168] In the embodiment of the present application, the description of perception request one can refer to the description in scenario one and will not be repeated here.

[0169] S720: The first management node sends a third perception report to the second management node. Correspondingly, the first management node receives the third perception report from the second management node.

[0170] Optionally, in an embodiment of the present application, Perception Report 3 includes the information included in Perception Report 1 corresponding to Scenario 1 (i.e., at least one of perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target movement direction information); the difference from Perception Report 1 corresponding to Scenario 1 is that, due to the need for a second perception, Perception Report 3 must include the identification of the perception target. The identification of the perception target is an identification assigned by the access network device to the perception target discovered in the first area after the access network device perceives the first area based on Perception Request 1.

[0171] For example, Table 3 takes perception report three including perception target identification list two and perception report three including perception target type information, perception target position information, perception target trajectory information, perception target speed information, and perception target moving direction information as an example, where #1 represents the identification of perception target 1, #2 represents the identification of perception target 2, and #3 represents the identification of perception target 3.

[0172] Table 3

[0173] S730: The second management node sends a third perception request to the first management node. Correspondingly, the first management node sends a fourth perception report to the second management node.

[0174] In an embodiment of the present application, the third perception request includes an identifier of a perception target. The identifier of the perception target included in the third perception request is part or all of the identifiers of the perception target included in the third perception report. That is, the first management node and / or the second management node determines one or more perception targets to be tracked based on the identifier of the perception data included in the third perception report. The third perception request includes the identifier of the one or more perception targets to be tracked.

[0175] In one possible implementation, the first management node sends perception report three to the second management node. The first management node does not determine the perception target to be tracked. The second management node determines one or more perception targets to be tracked based on the identifier of the perception target included in the received perception report three, and then the second management node sends perception request three including the identifier of the perception target to be tracked to the first management node.

[0176] In another possible implementation, the first management node determines one or more perception targets to be tracked based on the third perception report. The first management node sends the identifiers of the one or more perception targets to be tracked determined by the first management node and the corresponding partial perception report to the second management node. The second management node further determines one or more perception targets to be tracked based on the received partial perception report, and then the second management node sends a third perception request including the identifiers of the perception targets to be tracked to the first management node. For example, the first management node determines that the perception targets to be tracked are #1, #2, #3, and #4, and the second management node determines that the perception targets to be tracked are #1 and #2. The third perception request includes #1 and #2.

[0177] In another possible implementation, the third management node determines the perception target to be tracked. The third management node can be, for example, the first device described below, or other devices, which is not limited in the embodiments of the present application. In this implementation, after the first management node sends perception report three to the second management node, the second management node sends perception report three to the third management node. Further, the third management node determines the perception target to be tracked, and sends the identifier of the perception target to be tracked to the second management node, and then the second management node sends perception request three including the identifier of the perception target to be tracked to the first management node. It should be noted that the table of the above example is explained by taking the identifier of the perception target included in the perception request and the perception report as the identifier assigned by the access network device to the perception target as an example. The identifier of the perception target included in the perception request three can be the identifier assigned by the access network device to the perception target, or the identifier assigned by the first management node to the perception target, or the identifier assigned by the second management node to the perception target. Please refer to the description in S610 and will not be repeated here.

[0178] As described above, in an embodiment of the present application, the identification of the perception target included in the perception report three includes the identification of the perception target included in the perception request three. Exemplarily, the perception target is UVA, and the identification of the perception target included in the perception request three is part or all of the identifications of the UVA in the identification of the perception target included in the perception report three.

[0179] For example, perception request three includes perception target identification list three, wherein perception target identification list three (#1; #2) is the identification of some perception targets in perception target representation list two (#1; #2; #3). Perception target identification list three is shown in Table 4, wherein #1 identifies the identification of perception target 1, and #2 identifies the identification of perception target 2.

[0180] Table 4

[0181] S740: The first management node sends a fourth perception report to the second management node. Correspondingly, the second management node receives the fourth perception report from the first management node.

[0182] In an embodiment of the present application, perception report four is obtained by perceiving the perception target corresponding to the identification of the perception target, and perception report four includes at least one of the following items corresponding to the identification of the corresponding perception target: perception target type information, perception target position information, perception target trajectory information, perception target speed information, and perception target moving direction information.

[0183] For example, Table 5 takes perception report four including perception target type information, perception target position information, perception target trajectory information, perception target speed information, and perception target moving direction information as an example. Perception report four includes the perception report of the perception target corresponding to the identifier of each perception target in perception target identifier list three.

[0184] Table 5

[0185] In the perception method provided in the embodiment of the present application, the second management node carries at least one of the perception time information and the identification of the perception target in the perception request, so that the first management node manages the perception time (for example, it can reserve the time for perceiving the first service), or enables the first management node to manage the perception target corresponding to the identification of the perception target (for example, it can track and perceive the perception target corresponding to the identification of the perception target), and then sends a corresponding perception report to the second management node.

[0186] Figure 7 above describes the two-step perception process for scenario three. For ease of understanding, Figures 8 and 9 use a single perception as an example to further describe the perception method 600 shown in Figure 6. It should be noted that S610 and S620 are applicable to both the service-oriented management architecture and the 5G communication architecture.

[0188] S830: The first management node sends first information to the second management node. Correspondingly, the second management node receives the first information from the first management node.

[0189] In an embodiment of the present application, the first information is used to represent the sensing capability information of the first management node. This solution can enable the first management node to register the sensing capability information of the first management node with the second management node, so that the second management node can learn the sensing capability of the first management node, and further enable the second management node to send a sensing request within the sensing capability to the second management node.

[0191] In one possible implementation, the perception capability information includes a perception coverage level and / or a perception positioning accuracy, and the first information is information about registering the perception coverage level and / or the perception positioning accuracy. The first information sent by the first management node to the second management node is: a perception function node deployed by the first management node registers the perception coverage level and / or the perception positioning accuracy with the second management node.

[0192] Exemplarily, the perception coverage levels include: Level 1, for example, Level 1: 10m level, used for perception of daily low-altitude areas; Level 2, for example, Level 2: 1-10m level, used for perception of commercial routes and their associated spaces; Level 3, for example, Level 3: m level, used for, for example, UAV trajectory tracking, collision avoidance, etc.

[0193] Of course, the perceived coverage level may also include other coverage levels, which is not limited in the embodiments of the present application.

[0208] In the perception method provided in the embodiments of the present application, a perception report is obtained by analyzing and calculating perception data on the access network device. This solution can implement the perception function on the management plane, reducing the complexity of the first management node's external interface. Specifically, the entire process is as follows: first, the second management node sends a perception request to the first management node. Then, the first management node configures the access network device to perform perception based on the perception request. After performing perception, the access network device analyzes and calculates the obtained perception data to obtain a perception report. After sending the perception report to the first management node, the first management node sends the perception report to the second management node.
