Description

Technical Field

[0001] Embodiments of the present application relate to the field of sensing, and more specifically, to a sensing method and a sensing device. Background Art

[0002] The 3rd generation partnership project (3GPP) has proposed the functions and requirements of sensing communication services. The purpose of wireless sensing technology is to obtain characteristic information about remote objects or the environment without physically contacting the remote objects or the environment. Wireless sensing refers to the ability to use radio frequency signals to obtain information about the characteristics of the environment and / or objects in the environment (such as shape, size, direction, speed, position, distance, or relative motion between objects, etc.). Sensing data is data derived from wireless signals affected by the target object or the environment (such as reflection, refraction, diffraction). Wireless sensing can be applied to, for example, intruder / burglar detection applications (highways, railways, drone no-fly zones, yards, and homes), monitoring applications (rainfall, tourism, floods, breathing, and motion), navigation assistance applications, real-time map generation applications, or collision avoidance applications, etc. Exemplarily, for a drone no-fly zone monitoring application, a sensing base station with wireless sensing characteristics can be used to enable the sensing function within the no-fly zone, and by analyzing sensing data such as the reflection, refraction, and diffraction of radio frequency signals, it can sense whether a drone has intruded.

[0114] Figure 6 is an example of the perception method provided by the embodiments of the present application. This method is described by taking the interaction between the first management node and the second management node as an example. Of course, the entity that executes the actions of the first management node in this method may also be a device / module in the first management node, such as a chip, a processor, a processing unit, etc. in the first management node; the entity that executes the actions of the second management node in this method may also be a device / module in the second management node, such as a chip, a processor, a processing unit, etc. in the second management node. The embodiments of the present application do not make specific limitations on this. In the embodiments of the present application, the processing executed by a single execution entity (for example, the first management node or the second management node) may also be divided into being executed by multiple execution entities, and these execution entities may be logically and / or physically separated. Exemplarily, as Figure 6 described, method 600 includes:

[0115] 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.

[0116] Optionally, in the embodiments of the present application, the first management node configures access network devices for sensing the first service based on the sensing request, where the access network devices for sensing the first service include at least one access network device.

[0117] Exemplarily, the first service is used to configure the access network devices in a specific area to perform sensing, or the first service is used to configure the access network devices to perform sensing on a specific sensing target, or the first service is other services, and the embodiments of the present application do not limit this.

[0118] In the embodiments of the present application, the sensing request includes at least one of the following: sensing time information, or the identifier of the sensing target.

[0119] Among them, the sensing time information includes at least one of the following: the start time and end time for sensing the first service, or the sensing period of the first service. By including the sensing time information in the sensing request, the first management node can manage the sensing time of the first service, or support the scheduled sensing of the first service.

[0120] Exemplarily, the time when the second management node sends the sensing request to the first management node is 10:30, and the start time and end time for sensing the first service included in the sensing request are 11:30 and 11:45 respectively. Then the access network devices will sense the first service from 11:30 to 11:45. In other words, the access network devices start sensing the first service at 11:30 and end sensing the first service at 11:45. Or, exemplarily, the sensing request includes the sensing period of the first service as 30 minutes. Then the access network devices perform sensing on the first service every 30 minutes. For example, the access network devices sense the first service in the first 15 minutes of every 30 minutes.

[0121] Optionally, the identifier of the sensing target in the embodiments of the present application is the identifier of one sensing target; or the identifier of the sensing target in the embodiments of the present application is the respective identifiers of multiple sensing targets, that is, the identifier of each sensing target among multiple sensing targets. For example, the identifiers of multiple sensing targets are a list of identifiers of sensing targets, or a set of identifiers of sensing targets, and the embodiments of the present application do not limit this.

[0122] Optionally, the identifier of the sensed target is a unique identifier registered for the sensed target. For example, if the sensed target is an unmanned aerial vehicle (UAV), the identifier of the sensed target is the unique identifier registered for the UAV. Optionally, the sensed target is a pedestrian or an animal, and the identifier of the sensed target is used to identify the pedestrian or the animal. Optionally, the sensed target is another object, and the identifier of the sensed target is used to identify the other object.

[0123] Optionally, the identifier of the sensed target is the unique identifier of the sensed target assigned by the second management node.

[0124] Optionally, the identifier of the sensed target is the identifier of the sensed target assigned by the first management node, that is, the identifier of the sensed target under the first management node. Optionally, the second management node determines the unique identifier of the sensed target according to the identifier assigned by the first management node for the sensed 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 for the sensed target to determine the unique identifier of the sensed target; in another possible implementation, the second management node maps the identifier assigned by the first management node for the sensed target to the unique identifier of the sensed target under the second management node.

[0125] Optionally, the identifier of the sensed target is the identifier assigned by the access network device for the sensed target, which is the identifier of the sensed target under the access network device. Optionally, the first management node determines the identifier of the sensed target under the first management node according to the identifier assigned by the access network device for the sensed 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 for the sensed target to determine the identifier of the sensed target under the first management node; in another possible implementation, the first management node maps the identifier assigned by the access network device for the sensed target to the identifier of the sensed target under the first management node. Further, optionally, the second management node determines the unique identifier of the sensed target according to the identifier of the sensed target under the first management node determined by the first management node, and specific implementation can refer to the description in the above embodiments, which will not be elaborated here.

[0126] Exemplarily, the identifier of the sensed target in the access network device may be #1, the identifier in the first management node may be &1 or
, and the identifier in the second management node may be *1 or *
. The embodiments of the present application do not limit this.

[0127] It should be noted that in one possible implementation, the identifier of the sensed target is assigned by the access network device for the sensed target, and the first management node obtains the identifier of the sensed target assigned by the access network device by acquiring the sensing report.

[0128] Optionally, in the embodiments of the present application, the first management node configures the access network device for sensing the first service based on the sensing request, where the access network device is at least one access network device.

[0129] S620, the first management node sends a sensing report to the second management node. Correspondingly, the second management node receives the sensing report from the first management node.

[0130] In the embodiments of the present application, the sensing report includes at least one of the following: sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, sensing target moving direction information, and the identifier of the sensing target. In the embodiments of the present application, including the type of the sensing target in the sensing report enables the recipient of the sensing report (e.g., the first management node, the second management node) to determine the type of the target sensed by the access network device; including at least one of the location of the sensing target, the trajectory of the sensing target, the speed of the sensing target, and the moving direction of the sensing target in the sensing report enables the recipient of the sensing report (e.g., the first management node, the second management node) to determine the moving state of the target sensed by the access network device; including the identifier of the sensing target in the sensing report enables the recipient of the sensing report (e.g., the first management node, the second management node) to use the identifier of the sensing target to identify the unique target in the entire domain or region, and further, to implement the tracking of the sensing target.

[0131] Exemplarily, the sensing target type information is used to indicate the type of the sensing target, and the type of the sensing target may include, for example, pedestrians, animals, UAVs, etc.

[0132] Exemplarily, the sensing target location information includes one or more of the identifier of the cell where the sensing target is located, the identifier of the access network device corresponding to the sensing target, the tracking area identifier corresponding to the sensing target, and / or the geographical longitude, latitude, and altitude corresponding to the sensing target.

[0133] Exemplarily, the sensing target trajectory information includes the movement trajectory of the sensing target. Exemplarily, the movement trajectory of the sensing target includes one or more of the identifier of the cell where the sensing target is located, the identifier of the access network device corresponding to the sensing target, the tracking area identifier corresponding to the sensing target, and / or the geographical longitude, latitude, and altitude corresponding to the sensing target. For example, if the sensing target is a UAV, the sensing target trajectory is the flight route of the UAV; or for another example, if the sensing target is a pedestrian or an animal, the sensing target trajectory is the movement route of the pedestrian or the animal. Exemplarily, the sensing target speed information includes one or more of the X-axis speed, Y-axis speed, and Z-axis speed corresponding to the sensing target, where the X-axis, Y-axis, and Z-axis are the three-dimensional coordinates in the geodetic coordinate system.

[0134] Exemplarily, the perceived target movement direction information includes the perceived movement direction of the target. The perceived movement direction of the target may include the directions in which the target moves east, south, west, or north. For example, the target moves 30 m south, or the target moves 30 m north, or the target moves 30 m in the northeast direction, etc. The embodiments of the present application do not limit this.

[0135] In a possible implementation, the first management node sends a perception report to the second management node, including: the first management node sends a perception report to the second management node in response to a perception request. In other words, after receiving the perception request, the first management node is triggered to send a perception report to the second management node.

[0136] The perception method provided by the embodiments of the present application will be introduced in detail below in three scenarios:

[0137] Scenario 1: Perceive a specific area.

[0138] In this scenario, exemplarily, the perception request in step S610 is perception request 1, and perception request 1 includes perception time information. Exemplarily, perception request 1 is a regional perception request, that is, perception request 1 is used to request to perceive a specific area (for example, the first area) within the perception time corresponding to the perception time information. The first service is used to configure the access network devices in the first area to perform perception within 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 1, and the at least one access network device perceives the first area within the perception time corresponding to the perception time information. For example, if the access network devices covering the first area (or the service range of the access network devices is the first area) are base stations 1 to 10, then base stations 1 to 10 perceive the first area within the perception time corresponding to the perception time information and obtain the perception data corresponding to the first area.

[0139] Correspondingly, perception request 1 further includes at least one of the following: first area information, first area type information, perceived target type information, perceived number information, or service level agreement (SLA) metric information.

[0140] Exemplarily, the first area information is used to indicate the area information to be perceived, and may be a list of cell identifiers (such as physical cell identifier (PCI), cell identifier (ID), etc.), a list of base station identifiers (gNB ID), a list of tracking area identities (TAI), and / or geographical longitude and latitude area information.

[0141] Exemplarily, the first area type information is used to indicate the type corresponding to the first area. The area type may include, for example, ground, low altitude, water area, etc.

[0142] Exemplarily, the sensed target type information is used to indicate the type of the sensed target. The sensed target type may include, for example, pedestrians, animals, UAVs, etc.

[0143] Exemplarily, the sensed number information is used to indicate the maximum or minimum value of the number of targets to be sensed, including the number of sensed targets sensed for the first area in one sensing.

[0144] Exemplarily, the SLA metric information is used to indicate the SLA metric obtained after sensing the first area in the sensing report, or the SLA metric information is used to indicate the threshold of the SLA metric for sensing the first area. The SLA metric includes one or more of confidence level, positioning estimation accuracy, speed estimation accuracy, sensing resolution, maximum sensing service delay, refresh rate, missed detection rate, false detection rate. The parameters in the SLA metric information are introduced separately below.

[0145] The confidence level describes the degree of authenticity of the sensed data measured by the access network device used for sensing, and is identified by a percentage. For example, the confidence level can be set to 95% in the sensing request, then the credibility of the sensed data is 95%.

[0146] The positioning estimation accuracy describes the degree of proximity between the position of the sensed target obtained by the access network device used for sensing by executing the sensing request and its true position value.

[0147] The speed estimation accuracy describes the degree of proximity between the speed of the sensed target obtained by the access network device used for sensing by executing the sensing request and its true speed. Among them, the speed estimation accuracy can be calculated by the change in the moving position of the object sensed.

[0148] The sensing resolution describes the minimum difference between the measured value and the true value of different types of sensed targets allowed to be detected. For example, the sensing resolution of the distance that can detect whether a UAV exists can be 10 meters, and the sensing resolution of the speed is 10 m / s; the sensing resolution of the distance for tracking a flying UAV is 1 meter, and the sensing resolution of the speed is 1 m / s.

[0149] The maximum sensing service delay describes the maximum delay from the second management node sending the sensing request to the first management node reporting the sensing report. Or, it describes the maximum delay from the first management node configuring the access network device used for sensing to start executing the sensing task to the access network device used for sensing reporting the sensing report. The embodiments of the present application do not limit this.

[0150] The refresh rate describes the rate at which the access network device for sensing generates sensing data. For example, if sensing data is generated once every 1 second, the resolution is the reciprocal of the time interval, i.e., 0.1.

[0151] The miss detection rate describes the ratio of the undetected sensing targets or events to all sensing targets or events within any predetermined period when the access network device for sensing attempts to obtain sensing data.

[0152] The false detection rate describes the ratio of the sensed non-sensing targets or events to all sensed sensing targets or events within any predetermined period when the access network device for sensing attempts to obtain sensing data.

[0153] Correspondingly, in this scenario, exemplarily, the sensing report in step S620 is sensing report one, and sensing report one includes at least one of the following: sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, sensing target moving direction information. Among them, examples of sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, and sensing target moving direction information can refer to the descriptions in the above embodiments and will not be elaborated here.

[0154] In scenario one, sensing report one is obtained by sensing the first area, that is, the sensing report of area sensing. For example, if sensing target type information is included in sensing request one, and the type of the sensing target included in the sensing target type information is UVA, then correspondingly, sensing report one is the sensing report corresponding to one or more UVAs discovered by the access network device through sensing the first area. Optionally, the sensing report includes the identifier of the sensing target, which is used to determine one or more of the type information, location information, trajectory information, speed information, and moving direction information corresponding to the sensing target discovered by sensing the first area.

[0155] Scenario two: Sense a specific sensing target.

[0156] In this scenario, exemplarily, the sensing request in step S610 is sensing request two, and sensing request two includes the identifier of the sensing target. Exemplarily, sensing request two is a tracking sensing request, that is, sensing request two is used to request sensing of the sensing target corresponding to the identifier of the sensing target. For example, if the sensing target is moving, then tracking sensing of the sensing target is performed. It should be noted that the first management node configures at least one access network device to sense the sensing target corresponding to the identifier of the sensing target according to sensing request two, and the at least one access network device senses the sensing target corresponding to the identifier of the sensing target. For example, the first management node estimates the second area to the tenth area (i.e., the flight path of the sensing target) where the sensing target may move according to the movement track of the sensing target. The access network devices covering the second area to the tenth area are base stations 6 to 14 in sequence. Base stations 6 to 14 sense the sensing target corresponding to the identifier of the sensing target in sequence, and obtain sensing data of each base station sensing the sensing target corresponding to the identifier of the sensing target. That is, when the sensing target corresponding to the identifier of the sensing target moves to the second area, base station 6 senses the sensing target corresponding to the identifier of the sensing target and obtains sensing data. When the sensing target corresponding to the identifier of the sensing target moves to the third area, base station 7 senses the sensing target corresponding to the identifier of the sensing target and obtains sensing data, and so on, which will not be elaborated here.

[0157] Correspondingly, in this scenario, exemplarily, the sensing report in step S620 is sensing report two, and sensing report two includes at least one of the following: sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, sensing target moving direction information. Among them, examples of sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, and sensing target moving direction information can refer to the description of the above embodiments, which will not be elaborated here.

[0158] In scenario two, sensing report two is obtained by sensing the sensing target corresponding to the identifier of the sensing target, that is, the sensing report of tracking sensing. The above sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, and sensing target moving direction information are the type information, location information, trajectory information, speed information, and moving direction information of the sensing target corresponding to the identifier of the corresponding sensing target.

[0159] For example, the identifier of the sensing target included in sensing request two is identifier list one of the sensing target. Identifier list one of the sensing target is shown in Table 1, and sensing report two is shown in Table 2, where #1 represents the identifier of sensing target 1, #2 represents the identifier of sensing target 2, and #3 represents the identifier of sensing target 3.

[0160] Table 1

[0161] Perception Request Two #1 #2 #3

[0162] Taking the perception report two including the perception target type information, perception target location information, perception target trajectory information, perception target speed information, and perception target moving direction information as an example, the perception report two includes the perception reports of the perception targets corresponding to the identifiers of each perception target in the identifier list one of the perception targets.

[0163] Table 2

[0164]

[0165]

[0166] 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 two according to the perception report two. For example, the second management node determines to perform further perception on the perception target 1 and the perception target 2 according to the perception reports corresponding to the perception target 1, the perception target 2, and the perception target 3 shown in Table 2. Then, the second management node sends a perception request to the first management node again, and the perception request includes #1 and #2.

[0167] Scenario three: includes two perceptions. The first perception: perceiving a specific area, and the perception report three includes the identifiers of the perception targets; the second perception: perceiving a specific perception target.

[0168] This scenario includes the process of perceiving a specific area in Scenario one above and the process of perceiving a specific perception target in Scenario two. In other words, this scenario includes the two-way communication processes of the perception request in step S610 and the perception report in step S620. Exemplarily, as Figure 7 shown, the method 700 includes:

[0169] S710, the second management node sends a perception request one to the first management node. Correspondingly, the first management node receives the perception request one from the second management node.

[0170] In the embodiments of the present application, the description of the perception request one can refer to the description in Scenario one and will not be elaborated here.

[0171] S720, the first management node sends a perception report three to the second management node. Correspondingly, the first management node receives the perception report three from the second management node.

[0172] Optionally, in the embodiments of the present application, the third sensing report includes the information included in the first sensing report corresponding to Scenario 1 (i.e., at least one of the sensing target type information, the sensing target location information, the sensing target trajectory information, the sensing target speed information, and the sensing target moving direction information); the difference from the first sensing report corresponding to Scenario 1 is that since the second sensing is to be performed, the identification of the sensing target is mandatory in the third sensing report. The identification of the sensing target is an identification assigned by the access network device to the sensing target found in the first area after sensing the first area based on the first sensing request.

[0173] For example, Table 3 takes the third sensing report including the identification list two of the sensing target and the third sensing report including the sensing target type information, the sensing target location information, the sensing target trajectory information, the sensing target speed information, and the sensing target moving direction information as an example, where #1 represents the identification of sensing target 1, #2 represents the identification of sensing target 2, and #3 represents the identification of sensing target 3.

[0174] Table 3

[0175]

[0176] S730, the second management node sends the third sensing request to the first management node. Correspondingly, the first management node sends the fourth sensing report to the second management node.

[0177] In the embodiments of the present application, the third sensing request includes the identification of the sensing target. The identification of the sensing target included in the third sensing request is part or all of the identifications of the sensing targets included in the third sensing report, that is, the first management node, and / or, the second management node determines one or more sensing targets to be tracked according to the identifications of the sensing data included in the third sensing report, and the third sensing request includes the identifications of the one or more sensing targets to be tracked.

[0178] In a possible implementation, the first management node sends the third sensing report to the second management node, the first management node does not determine the sensing targets to be tracked, the second management node determines one or more sensing targets to be tracked according to the identifications of the sensing targets included in the received third sensing report, and then the second management node sends the third sensing request including the identifications of the sensing targets to be tracked to the first management node.

[0179] In another possible implementation, the first management node determines one or more sensed targets to be tracked according to the third sensed report. The first management node sends the identifiers of the one or more sensed targets to be tracked determined by the first management node and the corresponding partial sensed report to the second management node. The second management node further determines one or more sensed targets to be tracked according to the received partial sensed report, and then the second management node sends a third sensed request including the identifiers of the sensed targets to be tracked to the first management node. For example, the sensed targets determined by the first management node to be tracked are #1, #2, #3, #4, and the sensed targets determined by the second management node to be tracked are #1, #2. The third sensed request includes #1, #2.

[0180] In yet another possible implementation, the third management node determines the sensed targets to be tracked. The third management node may be, for example, the following first device, or other devices, and the embodiments of the present application do not limit this. In this implementation, after the first management node sends the third sensed report to the second management node, the second management node sends the third sensed report to the third management node. Further, the third management node determines the sensed targets to be tracked and sends the identifiers of the sensed targets to be tracked to the second management node. Then, the second management node sends a third sensed request including the identifiers of the sensed targets to be tracked to the first management node. It should be noted that the above example table is described by taking the identifiers of the sensed targets included in the sensed request and the sensed report as the identifiers assigned by the access network device to the sensed targets. The identifiers of the sensed targets included in the third sensed request may be the identifiers assigned by the access network device to the sensed targets, or the identifiers assigned by the first management node to the sensed targets, or the identifiers assigned by the second management node to the sensed targets. Reference may be made to the description in S610, which will not be elaborated here.

[0181] As described above, in the embodiments of the present application, the identifiers of the sensed targets included in the third sensed report include the identifiers of the sensed targets included in the third sensed request. Exemplarily, the sensed target is UVA, and the identifiers of the sensed targets included in the third sensed request are some or all of the identifiers of UVA included in the identifiers of the sensed targets included in the third sensed report.

[0182] For example, the third sensed request includes a list of identifiers of sensed targets three, where the list of identifiers of sensed targets three (#1; #2) is the identifiers of some of the sensed targets in the list of sensed targets two (#1; #2; #3). The list of identifiers of sensed targets three is shown in Table 4, where #1 identifies the identifier of sensed target 1 and #2 identifies the identifier of sensed target 2.

[0187] For example, taking the fourth sensing report including sensing target type information, sensing target location information, sensing target trajectory information, sensing target speed information, and sensing target moving direction information as an example, the fourth sensing report includes the sensing reports of the sensing targets corresponding to the identifiers of each sensing target in the identifier list three of the sensing targets.

[0193] S830, the first management node sends the first information to the second management node. Correspondingly, the second management node receives the first information from the first management node.

[0194] In the embodiments of the present application, the first information is used to characterize the sensing capability information of the first management node. This solution enables the first management node to register the sensing capability information of the first management node with the second management node, enabling the second management node to learn about the sensing capabilities of the first management node.

The first management node sending the first information to the second management node is: the sensing function nodes deployed by the first management node registering the sensing coverage level and / or the sensing positioning accuracy with the second management node.

[0197] Exemplarily, the sensing coverage levels include: level1, for example, level 1: 10m level, used for sensing in the daily low-altitude area; Level2, for example, level 2: 1 - 10m level, used for sensing in commercial air routes and the associated space; Level3, for example, level 3: m level, used for, for example, UAV trajectory tracking, anti-collision, etc.

[0198] Of course, the sensing coverage level may also include other coverage levels, and the embodiments of the present application do not limit this.

This solution can enable the sensing function to be implemented on the management plane and reduce the complexity of the external interface of the first management node. That is, the whole process is: First, the second management node sends a sensing request to the first management node. Secondly, the first management node configures the access network device to perform sensing according to the sensing request. After the access network device performs sensing, it analyzes and calculates the obtained sensing data to obtain a sensing report, and sends the sensing report to the first management node. Then, the first management node sends the sensing report to the second management node, and the whole process realizes a closed loop from the management plane to the access network device.
