[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] 5G sensing network architecture (e.g.) Figure 1As shown, the SF (Sensing Function) network element is divided into two parts: the control plane SF-C network element and the user plane SF-U network element. The SF network element can communicate with various network elements in the 5GC (5G Core Network) (such as AMF (Access and Mobility Management Function), UDM (Unified Data Management), SMF (Session Management Function), LMF (Location Management Function), NEF (Network Element Function), NRF (Network Repository Function), etc.) and can also directly connect to the RAN (Radio Access Network) to obtain sensing data from the RAN or UE (User Equipment).

[0047] In 5G sensing networks, user equipment (UEs) can act as sensing devices, detecting other targets, acquiring sensing data, and reporting it to SF network elements. However, most UEs acting as sensing devices are mobile, and their locations change in real time. Sensing tasks are performed on a region-by-region basis, requiring only the selection of sensing devices within the corresponding area, thus avoiding waste of air interface resources and equipment power consumption. Therefore, how to accurately select sensing devices is a crucial problem that urgently needs to be solved.

[0048] The sensing device selection method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the SF network element responds to a sensing task request carrying the sensing task area sent by the requesting network element, and determines the grid information corresponding to the sensing task area. Based on the grid information and / or the location information of candidate sensing devices, the SF network element selects the target sensing device from the candidate sensing devices.

[0049] Among them, sensing devices refer to devices with sensing functions in a sensing network. Sensing devices can be user terminals, such as mobile phones and computers, or smart wearable devices such as smart bracelets and smartwatches.

[0050] In one embodiment, Figure 2 This is a flowchart illustrating a sensing device selection method according to an embodiment of this application, applied to... Figure 1 Taking the SF network element as an example, the method includes the following steps:

[0051] S201, in response to a sensing task request carrying a sensing task area sent by a demanding network element, determine the raster information corresponding to the sensing task area.

[0052] In this context, "demand network element" refers to a network element device that senses service needs and issues sensing tasks; for example, it could be an AF (Application Function) network element. "Sensing task area" refers to the target area corresponding to the sensing task. "Sensing task request" refers to the request message for issuing the sensing task. "Grid information" refers to the information corresponding to each grid area within the sensing area.

[0053] Optionally, in this embodiment, the grid information corresponding to the sensing task area can be pre-configured, or the SF network element can perform gridding processing on the sensing task area after receiving the sensing task request, dividing the sensing task area into several grids and configuring the relevant information of each grid.

[0054] Optionally, in this embodiment, the grid information can be a grid list. The grid information includes, but is not limited to, at least one of the following: grid identifier, grid center coordinates, grid shape, and grid size.

[0055] As an optional implementation of this application, an information acquisition request is sent to the processing device, wherein the information acquisition request carries a sensing task area. This enables the processing device to feed back grid information of the sensing task area to the SF network element based on the information acquisition request.

[0056] Another optional implementation of this application is to perform rasterization processing on the perception task area, divide the perception task area into several grids, and configure the relevant information of each grid to obtain the grid information corresponding to the perception task area.

[0057] Another optional implementation of this application involves mapping the sensing task area to a local sensing grid to obtain the grid information corresponding to the sensing task area. Here, the sensing grids for each area are stored.

[0058] S202, Select the target sensing device from the candidate sensing devices based on grid information and / or the location information of the candidate sensing devices.

[0059] In this context, a candidate sensing device refers to a sensing device that is considered as an alternative, and there can be more than one candidate sensing device. A target sensing device refers to a sensing device that can perform the sensing task corresponding to the sensing task request.

[0060] An optional implementation of this application involves selecting a target sensing device from candidate sensing devices based on grid information. Specifically, a grid information acquisition request is sent to the candidate sensing devices, the request carrying grid information. The grid information acquisition request instructs the candidate sensing devices to determine the grid identifier of their current location based on the grid information and their own location information, and to report the grid identifier of their current location to the SF network element. Upon receiving the grid identifier of its current location, the SF network element identifies the candidate sensing devices whose grid identifier successfully matches the grid identifier in the grid information as the target sensing devices. It should be noted that if some candidate sensing devices are not located in the grids associated with the grid information, there is no need to report the grid identifier.

[0061] Another optional implementation of this application is to select a target sensing device from the candidate sensing devices based on grid information and the location information of the candidate sensing devices. Specifically, candidate sensing devices whose location information is located within the grid range of any grid associated in the grid information can be used as target sensing devices.

[0062] The aforementioned sensing device selection method, in response to a sensing task request carrying a sensing task area sent by a requesting network element, determines the grid information corresponding to the sensing task area. Based on the grid information and / or the location information of candidate sensing devices, a target sensing device is selected from the candidate sensing devices. In this application, upon receiving a sensing task request, the target sensing device can be accurately selected from the candidate sensing devices according to the grid information corresponding to the sensing task area and / or the location information of candidate sensing devices in the sensing task request. This achieves refined selection of suitable target sensing devices for sensing tasks, avoiding waste of air interface resources and power consumption of sensing devices.

[0063] In one embodiment, in order to reduce the computational burden on SF network elements and improve the utilization rate of terminal resources, such as Figure 3 As shown, an optional implementation of S202 includes:

[0064] S301, send grid information to the target device.

[0065] The target device is either a candidate sensing device or an LMF (Location Management Function) network element.

[0066] Optionally, in this embodiment, the grid information is pre-sent to the target device for storage. It should be noted that, in addition to storing the grid information of the sensing task area, the target device can also store grid information of other areas.

[0067] S302, if the grid information is successfully sent, send a device grid acquisition request to the target device.

[0068] Among them, the device grid acquisition request is used to instruct the target device to determine the grid identifier of the current grid of the candidate sensing device based on the location information and grid information of the candidate sensing device.

[0069] Optionally, in this embodiment, the device grid acquisition request carries at least one of the following: device identifier, request type, and request content; the request content includes the grid identifier and timestamp. The request type is event reporting.

[0070] Optionally, in this embodiment, an alternative implementation of sending a device grid acquisition request to the target device is as follows: when the target device is a candidate sensing device, the device grid acquisition request can be broadcast to a range (which needs to be larger than the sensing task area) so that all sensing devices within that range can receive the grid acquisition request. Sending grid information can also be done via broadcast.

[0071] Optionally, in this embodiment, the target device determines the grid identifier of the grid where the candidate sensing device is currently located based on the location information and grid information of the candidate sensing device. One possible implementation is that the candidate sensing device can determine the grid range of each grid based on the grid center coordinates, grid shape, and grid size. The candidate sensing device can determine its current grid location based on its own location information and the grid range of each grid, and thus determine the grid identifier of the current grid location.

[0072] Optionally, in some embodiments, the device grid acquisition request is further used to instruct the target device to report grid change information to the SF network element when the grid where the candidate sensing device is currently located changes. The grid change information includes the grid identifier of the changed grid, the device identifier of the candidate sensing device, and a timestamp. That is, the target device can acquire the location information of the candidate sensing device in real time or periodically. When the location information changes, it determines whether the grid corresponding to the changed location information has changed. If it has changed, it reports the grid change information to the SF network element. The device identifier refers to the unique identifier of the candidate sensing device, for example, it can be GPSI (Generic Public Subscription Identifier) ​​or SUPI (Subscription Permanent Identifier).

[0073] S303, Receive the device grid acquisition response message sent by the target device.

[0074] The device grid acquisition response message contains at least the grid identifier of the grid in which the candidate sensing device is currently located.

[0075] Optionally, in this embodiment, the device grid acquisition response message sent by the target device can be received directly or indirectly.

[0076] S304. Select the target sensing device from the candidate sensing devices based on the grid information and the grid identifier of the grid where the candidate sensing device is currently located.

[0077] Optionally, in this embodiment, the grid identifier of the current grid of the candidate sensing device is matched with the grid identifier of each grid in the grid information, and the candidate sensing device pointed to by the grid corresponding to the successfully matched grid identifier is taken as the target sensing device.

[0078] In this embodiment, grid information is sent to the target device for storage. If the grid information is successfully sent, a device grid acquisition request is sent to the target device. This request instructs the target device to determine the grid identifier of the grid currently occupied by the candidate sensing device based on its location information and the grid information. A device grid acquisition response message is received from the target device. Based on the grid information and the grid identifier of the candidate sensing device's current grid location, the target sensing device is selected from the candidate sensing devices. The device grid acquisition response message contains at least the grid identifier of the candidate sensing device's current grid location. The target device can be either a candidate sensing device or an LMF network element. This embodiment allows the target device to perform the task of confirming the grid identifier of the candidate sensing device's current grid location, improving the flexibility of target device determination, fully utilizing target device resources, and sharing the computational burden of the SF network element.

[0079] In one embodiment, to reduce the burden on sensing devices while increasing the flexibility of how target sensing devices are identified, such as... Figure 4 As shown, another optional implementation of S202 includes:

[0080] S401, Based on the location information of the candidate sensing device, determine the grid identifier of the grid in which the candidate sensing device is currently located.

[0081] As an optional implementation of this application, the SF network element can determine the grid range of each grid based on the grid center coordinates, grid shape, and grid size. The candidate sensing device can determine the current grid it is in based on its own location information and the grid range of each grid, and then determine the grid identifier of the current grid.

[0082] As another optional implementation of this application, for each candidate sensing device, the distance between the location information of the candidate sensing device and the coordinates of the center position of each grid is determined. The minimum distance is then selected. If the minimum distance is greater than a first preset threshold, the candidate sensing device is determined not to be in the sensing task area. If the minimum distance is less than a second preset threshold, the grid identifier of the grid pointed to by the center position coordinates of the grid corresponding to the minimum distance is used as the grid identifier of the grid where the candidate sensing device is currently located. The second preset threshold is less than the first preset threshold.

[0083] S402, Select the target sensing device from the candidate sensing devices based on the grid identifier and grid information of the grid where the candidate sensing device is currently located.

[0084] As an optional implementation of this application, the grid identifier and grid information of the current grid where the candidate sensing device is located are input into an intelligent analysis tool, and the intelligent analysis tool outputs the target sensing device. The intelligent analysis tool can be a trained neural network model.

[0085] Another optional implementation of this application is to match the grid identifier of the current grid of the candidate sensing device with the grid identifier of each grid in the grid information, and take the candidate sensing device pointed to by the grid corresponding to the successfully matched grid identifier as the target sensing device.

[0086] Optionally, in this embodiment, to obtain the location information of candidate sensing devices, one possible implementation of a sensing device selection method is to send a location acquisition request to the target device, so that the target device can feed back the location information of the candidate sensing devices to the SF network element based on the location acquisition request. Optionally, the location acquisition request includes at least one of the following: the device identifier of the candidate sensing device, the request type, and the request content. The request type includes periodic reporting and period length. The request content includes at least one of the following: the location information of the candidate sensing device (the absolute location of the candidate sensing device, for example, the location coordinates in the geodetic coordinate system) and a timestamp. Optionally, in this embodiment, the SF network element can send the location acquisition request to the target device after the candidate sensing device has completed its initial capability registration.

[0087] In this embodiment, a location acquisition request is sent to the target device to obtain the location information of candidate sensing devices. Based on the location information of the candidate sensing devices, the grid identifier of the current grid in which the candidate sensing device is located is determined. Based on the grid identifier and grid information of the current grid in which the candidate sensing device is located, the target sensing device is selected from the candidate sensing devices. This increases the flexibility of selecting the target sensing device, allowing users to flexibly choose the method of determining the target sensing device in different scenarios. In this embodiment, the target device only needs to provide the location information of the candidate sensing devices, reducing the computational load on the target device.

[0088] In one embodiment, such as Figure 5 As shown, an optional implementation of a sensing device selection method includes:

[0089] S501, in response to a sensing task request carrying a sensing task area sent by a requesting network element, determine the grid information corresponding to the sensing task area.

[0090] S502, send grid information to the target device. The target device is a candidate sensing device or an LMF network element.

[0091] S503, if the grid information is successfully sent, sends a device grid acquisition request to the target device.

[0092] S504, the target device determines the grid identifier of the grid in which the candidate sensing device is currently located based on the location information and grid information of the candidate sensing device.

[0093] S505, Receive a device grid acquisition response message sent by the target device. The device grid acquisition response message carries at least the grid identifier of the grid in which the candidate sensing device is currently located.

[0094] S506, based on the grid information and the grid identifier of the current grid of each candidate sensing device, select the target sensing device from among the candidate sensing devices. The device grid acquisition request carries at least one of the following: device identifier, request type, and request content; the request content includes the grid identifier and a timestamp. The device grid acquisition request is also used to instruct the target device to report grid change information to the SF network element when the current grid of the candidate sensing device changes; the grid change information includes the grid identifier of the changed grid, the device identifier of the candidate sensing device, and a timestamp.

[0095] In one embodiment, such as Figure 6 As shown, another alternative implementation of the sensing device selection method includes:

[0096] S601, the SF network element sends a location acquisition request to the target device. The location acquisition request includes at least one of the following: the device identifier of the candidate sensing device, the request type, and the request content; the request type includes periodic reporting and period length; the request content includes at least one of the following: the location information and the timestamp of the candidate sensing device.

[0097] S602, the target device sends the location information of the candidate sensing device back to the SF network element based on the location acquisition request.

[0098] S603, in response to a sensing task request carrying a sensing task area sent by a demanding network element, determines the raster information corresponding to the sensing task area.

[0099] S604, Based on the location information of the candidate sensing device, determine the grid identifier of the grid in which the candidate sensing device is currently located.

[0100] S605, select the target sensing device from among the candidate sensing devices based on the grid identifier and grid information of the grid where each candidate sensing device is currently located.

[0101] In this embodiment, in response to a sensing task request carrying a sensing task area sent by a requesting network element, the grid information corresponding to the sensing task area is determined. Based on the grid information and / or the location information of candidate sensing devices, a target sensing device is selected from the candidate sensing devices. In this application, upon receiving a sensing task request, the target sensing device can be accurately selected from the candidate sensing devices based on the grid information corresponding to the sensing task area and / or the location information of the candidate sensing devices in the sensing task request. This achieves refined selection of suitable target sensing devices for sensing tasks, avoiding waste of air interface resources and power consumption of sensing devices.

The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps.
