[0064] In the related technology, the sensing function (SF) can perform sensing service analysis based on the received sensing needs and provide sensing results, so that the network supports the sensing function. Specifically, the sensing task execution subjects include base stations and terminals, that is, the base station can send and receive signals to achieve the preliminary acquisition of sensing signals, or the base station and the terminal can cooperate to complete the transmission and reception of signals to achieve the preliminary acquisition of sensing signals; the base station processes the acquired sensing signals to generate sensing data; and the SF processes the sensing data to form sensing results. The basic functions of SF include sensing authorization, sensing control, data processing and result output; SF can be deployed independently or jointly with other network elements. Depending on the deployment method, SF can exist in two forms: sensing control plane function (SF-C, Sensing Function-Control Plane) and sensing user plane function (SF-U, Sensing Function-User Plane); for example, the communication sensing separation architecture such as Figure 1As shown, the communication perception separation architecture includes: SF-C, SF-U, user plane function (UPF, User Plane Function), (radio) access network ((R)AN, (Radio) Access Network), user equipment (UE, User Equipment), access and mobility management function (AMF, Access and Mobility Management), unified data management (UDM, Unified Data Management), network data analysis function (NWDAF, Network Data Analytics Function), positioning management function (LMF, Location Management Function), policy control function (PCF, Policy Control Function), network exposure function (NEF, Network Exposure Function), application function (AF, Application Function).

[0065] In the perception-related content discussed by 3GPP, regarding the division and management methods of perception areas, there is still the problem of how to form a consistent perception area division and processing between perception devices, core network perception network elements and perception demand parties (such as application platforms); therefore, it is necessary to clarify the unified division and processing mechanism of perception areas, and coordinate the mapping of perception areas between perception devices (such as base stations and terminals) and perception demand parties.

[0066] Based on this, in various embodiments of the present application, the first network function receives a first request sent by the second network function, and sends a first message to the second network function; the second network function sends a first request to the first network function, and receives the first message sent by the first network function; the first request carries information about the first perception area, and is used to request a subscription to a second perception area that can provide perception services within the first perception area; the first information represents information about the two-dimensional second perception area and / or information about the three-dimensional second perception area. In the above scheme, the first network function can receive a first request carrying information about the first perception area sent by the second network function, select a two-dimensional and / or three-dimensional second perception area that can provide perception services within the first perception area, and send the two-dimensional and / or three-dimensional second perception area to the second network function, that is, the first network function can process the received perception area information in the form of two-dimensional and / or three-dimensional, and manage and report the perception areas that can provide perception services in the form of two-dimensional and / or three-dimensional, thereby realizing unified processing of the perception areas through the first network function.

[0067] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0068] An embodiment of the present application provides a perception area management method, which is applied to a first network function. The first network function may be a network function with perception service control capability. The first network function may also be called a perception service control network function or a perception service control network element. The first network function may be located in the core network of the fifth generation mobile communication technology (5G, 5th Generation Mobile Communication Technology), the sixth generation mobile communication technology (6G, 6th Generation Mobile Communication Technology) or the future communication network. The first network function may be an independent functional network element or network function, such as SF or SF-C. The first network function may also be co-located with other network functions. For example, the first network function may be co-located with AMF. The first network function may be understood as an AMF with perception service control capability. For another example, the first network function may also be co-located with NEF or LMF. Figure 2 As shown, the method includes:

[0069] Step 201: Receive a first request sent by a second network function.

[0070] The first request carries information of the first perception area and is used to request subscription to a second perception area that can provide perception services within the first perception area.

[0071] Here, before receiving the first request sent by the second network function, the second network function needs to complete the relevant service contract with the network to determine the perception area range and perception service provided by the operator; when receiving the first request sent by the second network function, the perception service that the second network function can request is confirmed according to the contract information of the second network function. The contract information of the second network function can be obtained from the UDM and / or the Unified Data Repository (UDR).

[0072] It should be noted that the first request can be understood as a request for subscription to perception area information; the first perception area can be understood as the area that the second network function requests to perceive, and can also be called the target perception area; the second perception area can be understood as the area within the first perception area that can currently provide perception services or perception capabilities, that is, the second perception area is less than or equal to the first perception area, and the second perception area can also be called the actual perception area or the actual perception capability area.

[0073] Step 202: Send first information to the second network function.

[0074] The first information represents information of a two-dimensional second perception area and / or information of a three-dimensional second perception area.

[0075] Here, when the first perception area intersects with the perception area that can currently provide perception services, the first information is sent to the second network function; or, when the second network function has signed a perception service and the first perception area intersects with the perception area that can currently provide perception services, the first information is sent to the second network function.

[0076] In order to save signaling overhead and transmission resources, in one embodiment, sending the first information to the second network function includes:

[0077] In a case where the first perception area is located within a fifth perception area, first information is sent to the second network function, where the fifth perception area represents a perception area subscribed by the second network function.

[0078] Here, before receiving the first request sent by the second network function, the second network function needs to complete the relevant business contract with the network to determine the fifth perception area; when the first perception area is located in the fifth perception area, that is, the first perception area is less than or equal to the fifth perception area, the representation can provide perception services to the second network function and send the first information to the second network function; the fifth perception area can also be called a contracted perception area or a contracted perception capability area.

[0079] In the case where the first perception area is outside the fifth perception area, or there is no overlapping coverage area between the first perception area and the fifth perception area, the first request is refused to be responded to, and the first information is not sent to the second network function to reduce unnecessary signaling overhead.

[0080] In order to determine the awareness area that can provide the awareness service to the second network function, in one embodiment, the method further includes:

[0081] The first information is determined based on second information, where the second information indicates position information corresponding to a third perception area in a set two-dimensional plane grid area and / or a three-dimensional grid area where the first perception device can provide perception services.

[0082] Here, in the case of receiving the first request sent by the second network function, the perception area that can currently provide perception services within the first perception area is determined according to the second information, that is, the second perception area is determined according to the intersection of the first perception area and the third perception area, thereby determining the first information; the first perception device is any perception device managed by the first network function, or any perception device that has registered perception capabilities with the first network function, and the perception capabilities include perception ranges. The second perception area belongs to the intersection of the first perception area and the third perception area, or the second perception area is located in the overlapping area of ​​the first perception area and the third perception area.

[0083] The first network function manages the third perception area in which the first perception device can provide perception services in units of a set two-dimensional plane network and / or a three-dimensional grid to achieve unified division and management of the perception area.

[0084] In order to ensure that the second network function can obtain the perception service, in one embodiment, the method further includes:

[0085] receiving a second request sent by the second network function; wherein the second request carries third information for requesting a perception service, the third information representing information of a fourth two-dimensional perception area and / or information of a fourth three-dimensional perception area; the fourth perception area is smaller than or equal to the second perception area;

[0086] A third request is sent to the second sensing device; the third request indicates providing a sensing service in the fourth sensing area; the second sensing device represents a first sensing device that can provide a sensing service for the fourth sensing area.

[0087] Here, when the second request sent by the second network function is received, based on the third information carried by the second request, a perception device that performs the perception service is selected from the first perception device managed by the first network function, that is, the second perception device is selected, and a third request is sent to the selected second perception device; the second request can be understood as a perception service startup request; the third request can be understood as a request to execute the perception service; the fourth perception area can be understood as the actual area where the second network function requests the perception service, which can also be called the perception operation area or the perception area for performing the perception operation.

[0088] The fourth perception area is smaller than or equal to the second perception area, which can be understood as the fourth perception area is located in the second perception area, or the second perception area covers the fourth perception area.

[0089] It should be noted that if Figure 3 As shown, the size relationship between the first perception area, the second perception area, the fourth perception area and the fifth perception area is: the fourth perception area ≤ the second perception area ≤ the first perception area ≤ the fifth perception area.

[0090] In order to ensure that the second network function can obtain the perception service in the fourth perception area, in one embodiment, the method further includes:

[0091] Based on the second information and the third information, a second sensing device is determined; wherein,

[0092] The second information indicates the location information corresponding to the third perception area in the set two-dimensional plane grid area and / or three-dimensional grid area where the first perception device can provide perception services.

[0093] Here, when the fourth perception area is located within the coverage of the third perception area where any first perception device can provide perception services, the first perception device can be determined as the second perception device; when the fourth perception area is located within the coverage of the third perception area where multiple first perception devices can provide perception services, the multiple first perception devices can all be determined as second perception devices, that is, a combination of multiple second perception devices provides perception services and performs perception operations, and the third perception area where the multiple second perception devices can provide perception services is greater than or equal to the fourth perception area.

[0094] In order to manage the sensing area information of the sensing device in real time so as to accurately determine the sensing area that can provide the sensing service to the second network function, in one embodiment, the method further includes:

[0095] receiving fourth information sent or updated by the first sensing device, where the fourth information at least includes two-dimensional position information and / or three-dimensional position information of a third sensing area for which the sensing device can provide sensing services;

[0096] The second information is determined or updated based on the fourth information, where the second information indicates the position information corresponding to the third perception area in the set two-dimensional plane grid area and / or three-dimensional stereo grid area where the first perception device can provide perception services.

[0097] Here, in the case of receiving the fourth information sent or updated by the first perception device, the third perception area in which the perception device can provide perception services included in the fourth information is managed in units of two-dimensional plane grids and / or three-dimensional grids, that is, the two-dimensional position information and / or three-dimensional position information of the third perception area is converted into a two-dimensional plane grid area and / or a three-dimensional grid area; based on the converted two-dimensional plane grid area and / or three-dimensional grid area, the second information is determined or updated; wherein the management operation may include storage, deletion, and deduplication. In the case of receiving the fourth information sent or updated by the first perception device, a first response may also be sent to the first perception device to indicate that the fourth information has been successfully received.

[0098] It should be noted that the fourth information may be carried in the sensing capability registration request or sensing capability update request sent by the first sensing device; the fourth information may also include the sensing data processing level and the supported sensing data type. When the third sensing area in which the first sensing device can provide sensing services changes, the updated fourth information sent by the first sensing device may be received, so that the first network function can manage the sensing area information of the sensing device in real time, thereby being able to accurately determine the sensing area in which the sensing service can be provided to the second network function.

[0099] In order to achieve unified management of the perception area, in one embodiment, determining or updating the second information based on the fourth information includes:

[0100] Based on the fourth information, the third perception area is mapped to a set two-dimensional plane grid area and / or a three-dimensional grid area to obtain fifth information, where the fifth information represents position information corresponding to the third perception area in the set two-dimensional plane grid area and / or the three-dimensional grid area;

[0101] The second information is determined or updated based on the identifier of the first sensing device and the fifth information, where the second information includes a corresponding relationship between the identifier of the first sensing device and the fifth information.

[0102] Here, the two-dimensional position information and / or three-dimensional position information of the third perception area is mapped to a two-dimensional plane grid area and / or a three-dimensional stereo grid area to obtain the fifth information; the two-dimensional plane grid and / or the three-dimensional stereo grid are the minimum management units of the perception areas uniformly divided by the core network, and the size of the two-dimensional plane grid and / or the three-dimensional stereo grid can be determined according to the actual application scenario.

[0103] It should be noted that the two-dimensional position information of the third sensing area can be in the form of a square or a sector, or in the form of a minimum management area divided by combining sectors and points. For example, Figure 4 In the fan-shaped point arrangement method shown, the two-dimensional position information of the third perception area can be based on the smallest grid therein; that is, the size and shape of the smallest management unit of the two-dimensional perception area of ​​the first perception device can be the same as or different from the size and shape of the two-dimensional plane grid; the three-dimensional position information of the third perception area can be in the form of a cube, and the length, width and height of the cube can be set by the first perception device and can be different from the length, width and height of the three-dimensional grid. In other words, the smallest management unit of the perception area of ​​the first perception device can be the same as or different from the smallest management unit of the perception area of ​​the first network function.

[0104] It should be noted that the fifth information may be an identifier of a two-dimensional plane grid and / or an identifier of a three-dimensional solid grid. For example, the two-dimensional plane and / or the three-dimensional solid space is divided into two-dimensional plane grids and / or three-dimensional solid grids, and the two-dimensional plane grids and / or three-dimensional solid grids are numbered, the two-dimensional position information and / or three-dimensional position information of the third perception area is mapped to the two-dimensional plane grid area and / or the three-dimensional solid grid area, and the numbers of the two-dimensional plane grids and / or three-dimensional solid grids that fully cover or cover a certain proportion of the third perception area are recorded to obtain the fifth information; the correspondence between the numbers of the two-dimensional plane grid areas and / or three-dimensional solid grid areas corresponding to the third perception area and the identifier of the first perception device is recorded, so as to determine or update the second information. For another example, the two-dimensional plane may also be divided by a region division method that combines sectors and points, that is, the two-dimensional plane grid may also be a unit area divided by a region division method that combines sectors and points, for example Figure 4 That is to say, the shape and size of the two-dimensional plane grid and the three-dimensional solid grid can be determined according to actual needs.

[0105] For example, when the third perception area is two-dimensional, the two-dimensional position information of the third perception area is mapped to a two-dimensional plane grid area, such as Figure 5 As shown, the bottom-layer squares are the two-dimensional plane grid areas uniformly divided by the core network, the twill grids are the third perception areas where the first perception device A can provide perception services, and the diamond grids are the third perception areas where the first perception device B can provide perception services; the twill grids are mapped to the bottom-layer squares to obtain the position information corresponding to the first perception device A in the two-dimensional plane grid area, thereby obtaining the fifth information; the diamond grids are mapped to the bottom-layer squares to obtain the position information corresponding to the first perception device B in the two-dimensional plane grid area, thereby obtaining the fifth information; based on the fifth information and the identifiers A and B of the first perception device, the second information is determined or updated.

[0106] For another example, when the third perception area is three-dimensional, the core network uniformly divides the three-dimensional grid area into three-dimensional grid areas, such as Figure 6 As shown, the core network divides the stereoscopic perception area into 16 equal cubic blocks; the first network function receives the fourth information sent by the first perception device C, such as Figure 7 As shown, the diagonal grid is the third sensing area where the first sensing device C can provide sensing services. The third sensing area where the first sensing device C can provide sensing services is mapped to Figure 6 The three-dimensional grid area of ​​the third sensing area is obtained, and the three-dimensional grid numbers corresponding to the third sensing area are 6, 7, 10, and 11; the fourth information sent by the first sensing device D is received, such as Figure 8 As shown, the diamond grid is the third perception area where the first perception device D can provide perception services. The third perception area where the first perception device D can provide perception services is mapped to Figure 6 The three-dimensional grid area corresponding to the third perception area is numbered 7, 8, 11, and 12; combined with the fourth information sent by the first perception device C and the first perception device D, the fifth information obtained is the three-dimensional grid area 6, 7, 8, 10, 11, and 12, among which the three-dimensional grids 7 and 11 correspond to the first perception device C and the first perception device D.

[0107] In order to ensure that all managed perception areas that can provide perception services can provide perception services, in one embodiment, the fifth information includes the identification or location information of the two-dimensional plane grid fully covered by the third perception area, and / or the identification or location information of the three-dimensional grid fully covered by the third perception area.

[0108] Here, after the third perception area is mapped to the two-dimensional plane grid area and / or the three-dimensional solid grid area, the two-dimensional plane grid and / or the three-dimensional solid grid fully covered by the third perception area is regarded as the three-dimensional third perception area that can provide perception services. For example, Figure 7 The three-dimensional third perception area that can provide perception services is the three-dimensional grid 6, 7, 10, 11, Figure 8 The three-dimensional third perception area that can provide perception services is the three-dimensional grids 7, 8, 11, and 12; the two-dimensional plane grids and / or three-dimensional grids that are not fully covered are regarded as having no perception capabilities.

[0109] In order to uniformly manage the perception area and facilitate the search for the perception area, the location of the perception area can be represented by the identification or location information of the two-dimensional plane grid or the three-dimensional grid. Based on this, in one embodiment, the information of the two-dimensional perception area includes: the identification or location information of the two-dimensional plane grid that is fully covered by the perception area in the set two-dimensional plane grid area; and / or,

[0110] The information of the three-dimensional perception area includes: identification or position information of the three-dimensional grid that is fully covered by the perception area in the set three-dimensional grid area.

[0116] The embodiment of the present application provides a perception area management method, which is applied to a second network function. The second network function may be a network function with a perception service requirement, such as AF. Fig. 9 As shown, the method includes:

[0117] Step 901: Send a first request to a first network function.

[0118] The first request carries information of the first perception area and is used to request subscription to a second perception area that can provide perception services within the first perception area.

[0119] Here, the second network function sends a first request to the first network function when there is a perception demand and the second network function and the first network function have signed a contract for related services.

[0120] Step 902: Receive first information sent by the first network function.

[0121] The first information represents information of a two-dimensional second perception area and / or information of a three-dimensional second perception area.

[0123] determining third information based on the first information, the third information representing information of a fourth two-dimensional perception area and / or information of a fourth three-dimensional perception area, the fourth perception area being smaller than or equal to the second perception area;

[0124] Send a second request to the first network function; the second request carries the third information and is used to request the perception service.

[0125] Here, when the first information is received, the third information is determined based on the first information, and the second request is sent to the first network function. Specifically, the fourth perception area is determined from the second perception area, so as to determine the perception area where the perception device needs to finally perform the perception service, so as to reduce the perception range of the perception task performed by the perception device, speed up the efficiency of the perception device in providing perception data, and improve the accuracy of the perception data.

[0126] The present application is further described in detail below in conjunction with application examples.

[0127] This application can be applied to the perception service architecture of 5G or future 6G. Fig.10 As shown, the perception area management method includes the following steps:

[0128] Step 1: The sensing device sends fourth information to the first network function, where the fourth information at least includes two-dimensional position information and / or three-dimensional position information of a third sensing area for which the sensing device can provide sensing services.

[0129] Here, the sensing device can be understood as the first sensing device mentioned above. When the third sensing area is two-dimensional, the first sensing device can send the fourth information to the first network function in the form of a fan or a grid; when the third sensing area is a three-dimensional area, the first sensing device can send the fourth information to the first network function in the form of a cube of a fixed size; the length, width and height of the cube can be set by the first sensing device and can be different from the size of the three-dimensional grid.

[0130] Step 2: The first network function determines or updates the second information based on the fourth information.

[0131] Here, upon receiving the fourth information, the first network function maps the third perception area to a two-dimensional plane grid area and / or a three-dimensional grid area based on the fourth information to determine or update the second information, that is, the first network function performs normalized management of the third perception area.

[0132] Step 3: The second network function sends a first request to the first network function.

[0133] Here, the second network function requests the first network function for the perception service when the perception service is needed.

[0134] Step 4: The first network function determines the first information based on the second information.

[0135] Here, the first network function determines the perception area (second perception area) that can actually provide perception services to the second network function based on the perception area (first perception area) for which the second network function requests perception services and the perception area of ​​the perception device managed by the first network function (third perception area).

[0136] Step 5: The first network function sends the first information to the second network function.

[0137] Here, for the specific implementation process of step 5, please refer to the relevant description above, which will not be repeated here.

[0138] Step 6: The second network function determines third information based on the first information.

[0139] Here, the second network function determines the perception area (fourth perception area) where the perception operation finally needs to be performed based on the perception area in which the first network function can actually provide perception services.

[0140] Step 7: The second network function sends a second request to the first network function.

[0141] Here, for the specific implementation process of step 7, please refer to the relevant description above, which will not be repeated here.

[0142] Step 8: The first network function sends a third request to the sensing device.

[0143] Here, when the first network function receives the second request, based on the second request, it selects a second perception device that performs the perception operation from the managed perception devices, and sends a third request to the selected second perception device. When the second perception device receives the third request, it performs the perception operation and reports the perception data to the first network function; the first network function processes the perception data to form a perception result, and sends the perception result to the second network function. Currently, when the second perception device has the ability to process perception data, the second perception device processes the perception data to obtain the perception result, and sends the perception result to the first network function, and the first network function forwards the perception result to the second network function.
