[0092] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0093] Unless specifically stated otherwise, the relative arrangement of components and steps, the numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure.

[0094] At the same time, it should be understood that for the convenience of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0095] Technologies, methods, and apparatus known to ordinary technicians in the relevant field may not be discussed in detail, but where appropriate, such technologies, methods, and apparatus should be considered part of the authorization specification.

[0096] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0097] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0098] Through research, the inventors discovered that, while base stations are capable of providing sensing services, unlike terminals, they cannot share their configuration information with third-party AF (Application Function) servers. Furthermore, third-party AF servers cannot directly request a connection with the base station by reporting an ID, as terminals do. Therefore, implementing sensing services requires effective management of different scenarios and the associated terminals and base stations.

[0099] The inventors also discovered through research that, in related technology perception services, because the 3GPP SA1 specification for network perception capabilities includes both terminal-based and base station-based perception services, in the terminal-based perception model, a third-party AF can obtain terminal-related information, report the terminal ID to the network, establish a connection with the corresponding terminal, and directly transmit data.

[0100] However, in the related technologies based on base station sensing capabilities, since base station information is not open to third-party AFs, third-party AFs cannot describe their sensing service needs by reporting base station IDs, and base stations cannot directly establish connections with AFs and transmit data. Furthermore, due to the large amount of sensing data involved in sensing services, avoiding excessive network load caused by the transmission of large amounts of raw sensing data is also a challenge in related network sensing services.

[0101] In view of at least one of the above technical problems, in order to enable a third-party AF to more effectively initiate a request for a perception service, and to enable base stations and terminals with perception capabilities to cooperate to perform related perception operations and transmit perception data, the present disclosure provides a perception service method and system, a perception function network element, a core network, and a storage medium. By having the AF directly report scene information that needs to be perceived, the network-side perception function network element can more effectively manage base stations and terminals with perception capabilities in the perception service. The present disclosure is described below through specific embodiments.

[0102] FIG1 is a schematic diagram of some embodiments of the sensing service method disclosed herein. Preferably, this embodiment can be performed by a sensing function (SF) or core network device or sensing service system disclosed herein. As shown in FIG1 , the method of the embodiment of FIG1 may include steps 100 and at least one of steps 300 to 500, wherein:

[0103] Step 100: The perception function network element receives a perception data request sent by the application function server, wherein the perception data request includes perception scenario information.

[0104] In some embodiments of the present disclosure, the perceived scene information is spatial information of the scene to be perceived, including center point position information and corresponding length, width, height or radius information.

[0105] In some embodiments of the present disclosure, the perception data request may also include perception requirements, where the perception scene content is the spatial information of the scene that needs to be perceived, and the perception requirements are determined by the application function server based on the actual requested perception service needs and reported to the network side.

[0106] In some embodiments of the present disclosure, step 100 may include: the perception function network element receives a perception data request forwarded by the application function server through a NEF (Network Exposure Function).

[0107] In some embodiments of the present disclosure, step 100 may include: the perception service application function AF sends a perception data request to the network open function NEF on the network side, and reports the perception scene information and perception requirements. The perception scene content is the spatial information of the scene that needs to be perceived, including the center point location information and the corresponding length, width, height or radius information. The perception requirement is determined by the application function AF based on the actual requested perception service needs and reported to the network side; after receiving the perception request, perception scene information and perception requirements, the network open function NEF forwards this request and related information to the network perception function SF.

[0108] In some embodiments of the present disclosure, a third-party AF determines relevant perception scenarios and perception requirements based on the actual needs of the perception service. The perception scenario is determined by the AF itself and is a three-dimensional space, including the location of a center point and data such as length, width, height, or radius based on the center point to describe the spatial information of the scene. Perception requirements include perception operations and perception data, which are specific requirements related to the perception service.

[0109] Figure 2 is a schematic diagram of a perception scenario in some embodiments of the present disclosure. As shown in Figure 2, each dotted circle represents a perception scenario defined by an AF based on actual perception service requirements. Since the AF cannot determine whether there will be or which base stations in the scenario have the perception capability to obtain perception data, the AF only needs to report the requested location information and spatial information of the perception scenario and the requested corresponding perception requirements to the network. The corresponding perception capability base stations and perception capability terminals in the specific scenario and the type of perception capabilities they possess are all determined by the network side.

[0110] In some embodiments of the present disclosure, the service perception method of the present disclosure may further include step 200, wherein:

[0111] Step 200: The perception function network element allocates an exclusive scene identifier for the perception scene information.

[0112] In some embodiments of the present disclosure, step 200 may include: the perception function network element assigning an exclusive scene identifier to the perception scene information; and the perception function network element establishing a correspondence between the perception requirement and the scene identifier.

[0113] In some embodiments of the present disclosure, step 200 may include: after receiving the request and the perception scene information and the perception requirement, the network perception function SF creates a unique scene ID for the perception scene, and corresponds the corresponding perception requirement to the scene ID.

[0114] Step 300: The perception function network element determines the perception capability devices existing in the perception scenario, wherein the perception capability devices include at least one of a perception capability terminal and a perception capability base station.

[0115] In some embodiments of the present disclosure, the sensing capability terminal may be a mobile phone, a smart street lamp, a smart sensor, a personal computer, or other terminal device.

[0116] In some embodiments of the present disclosure, the sensing capability terminal may be a network access side device such as a wireless access point (AP), a router, or a switch.

[0117] In some embodiments of the present disclosure, step 300 may include: the perception function network element reports the perception scenario information to the NRF (Network Repository Function) to query the base stations with perception capabilities under the perception scenario information; the perception function network element receives the identification information of all base stations with perception capabilities under the perception scenario information returned by the network repository function network element.

[0118] In some embodiments of the present disclosure, step 300 may include: after creating the scene ID, the perception function SF reports the scene information to the NRF for query, queries which specific base stations with perception capabilities are in this scene, and requests the NRF to return the ID information of the relevant base stations; after receiving the request, the NRF queries the relevant perception capability base stations, and returns all the ID information of all base stations with perception capabilities in this scene to the SF. After receiving the perception capability base station ID, the SF matches the scene ID with the perception capability base station ID.

[0119] In some embodiments of the present disclosure, if the NRF does not find a base station capable of sensing after querying, an empty request is returned to the SF to inform the SF that there is no base station capable of sensing in this scenario.

[0120] In some embodiments of the present disclosure, step 300 may include: the perception function network element reports the perception scenario information to the AMF (Access and Mobility Management Function) and queries the terminals with perception capabilities under the perception scenario information; the perception function network element receives the identification information of all terminals with perception capabilities under the perception scenario information returned by the access and mobility management function network element.

[0121] In some embodiments of the present disclosure, step 300 may include: after creating the scenario ID, the perception function SF reports the scenario information to the AMF to query the information of terminals with perception capabilities. The AMF queries which specific terminals with perception capabilities are in this scenario and requests the AMF to return the ID information of the relevant terminals. After receiving the request, the AMF queries the relevant perception-capable terminals and returns the ID information of all terminals with perception capabilities in this scenario to the SF. After receiving the perception-capable terminal ID, the SF matches the scenario ID with the perception-capable terminal ID.

[0122] In some embodiments of the present disclosure, if there is no perception-capable terminal after the AMF query, an empty request is returned to the SF to inform the SF that there is no perception-capable terminal in this scenario.

[0123] Step 400: The perception function network element determines the scene classification of the perception scene according to the perception capability devices existing in the perception scene.

[0124] In some embodiments of the present disclosure, step 400 may include at least one of steps 410 to 430, wherein:

[0125] In step 410, the perception function network element queries the base station and terminal configuration information. If it is determined that both a perception-capable base station and a perception-capable terminal exist in the perception scene, the scene classification of the perception scene is determined to be a first type of scene (scene A, full perception scene).

[0126] In step 420, the perception function network element queries the base station and terminal configuration information. If it is determined that there is a perception-capable terminal but no perception-capable base station in the perception scene, the scene classification of the perception scene is determined to be the second type of scene (scene B, terminal perception scene).

[0127] In step 430, the perception function network element queries the base station and terminal configuration information. If it is determined that there is no perception-capable terminal but there is a perception-capable base station in the perception scene, the scene classification of the perception scene is determined to be the third type of scene (C scene, base station perception scene).

[0128] Figure 3 is a schematic diagram illustrating the classification of perception scenarios in some embodiments of the present disclosure. As shown in Figure 3, a fully perceptual scenario specifically involves a scenario provided by the AF where the perception function network element (SF) queries base station and terminal configuration information and discovers the presence of both a perception-capable base station and a perception-capable terminal within the scenario. This is illustrated by scenario A in Figure 3.

[0129] The terminal perception scenario is as follows: within the scenario provided by the AF, the perception function network element SF queries the base station and terminal configuration information and finds that there are only perception-capable terminals in the scenario, but no perception-capable base stations. This is shown in scenario B in Figure 3.

[0130] The base station sensing scenario is as follows: within the scenario provided by the AF, the sensing function network element SF queries the base station and terminal configuration information and finds that there are only sensing-capable base stations in the scenario, but no sensing-capable terminals. This is shown in scenario C in Figure 3.

[0131] Step 500: The perception function network element performs relevant perception request operations according to the scene classification of the perception scene.

[0132] In some embodiments of the present disclosure, steps 400 to 500 may include: after receiving all information from all base stations and terminals with perception capabilities under this scene ID, the perception function SF determines which scene among ABC this perception scene belongs to, matches this scene ID with the scene classification, and then executes relevant perception request operations according to the specific scene classification.

[0133] In some embodiments of the present disclosure, step 500 may include: the sensing function network element SF may perform different operations after allocating an ID to the scene reported by the AF and confirming the classification.

[0134] In some embodiments of the present disclosure, step 500 may include at least one of steps 510 to 550, wherein:

[0135] Step 510: The perception function network element determines a perception capability device according to the scene classification of the perception scene.

[0136] In some embodiments of the present disclosure, step 510 may include: when the scene classification of the perception scene is a first type of scene, the perception capability devices existing in the perception scene include a perception capability base station and a perception capability terminal; when the scene classification of the perception scene is a second type of scene, the perception capability devices existing in the perception scene include a perception capability terminal; when the scene classification of the perception scene is a third type of scene, the perception capability devices existing in the perception scene include a perception capability base station.

[0137] Step 520: The perception function network element requests the perception capability device to access the perception function network element.

[0138] In some embodiments of the present disclosure, when the scenario classification of the perception scenario is a first type scenario or a second type scenario, step 520 may include: the perception function network element sends an access request to the access and mobility management function network element, requesting all perception capability terminals in the perception scenario to access the network and establish a connection with the perception function network element; the perception function network element receives terminal configuration information of all perception capability terminals in the perception scenario sent by the mobility management function network element, wherein, after receiving the access request, the access and mobility management function network element sends the terminal configuration information to the perception function network element, and at the same time sends a perception capability terminal access request to the perception capability terminal through the base station, requesting the perception capability terminal to establish a connection with the perception function network element through the user plane function network element.

[0139] In some embodiments of the present disclosure, when the scene classification of the perception scene is a first type scene or a third type scene, step 520 may include: the perception function network element sends an access request to the network repository function network element, requesting the network repository function network element to send the configuration information of the corresponding perception capability base station; after receiving the configuration information of the perception capability base station, the perception capability network element directly sends a base station access request to the corresponding perception capability base station, requesting the perception capability base station to respond and access the perception capability network element.

[0140] Step 530: The sensing function network element sends a sensing operation request to the sensing capability device, instructing the sensing capability device to perform the sensing operation.

[0141] Step 540: The perception function network element receives the perception data returned by the perception capability device.

[0142] Step 550: The perception function network element sends the returned perception data to the application function server.

[0143] In some embodiments of the present disclosure, step 550 may include: the perception function network element performs relevant processing on the returned perception data, wherein the relevant processing includes at least one of security check, integrity check, classification, and compression; the perception function network element forwards the processed perception data to the application function server through the network open function network element.

[0144] The above-mentioned embodiments of the present disclosure design a service model based on perception scenarios. By having the AF directly report the scenario information that needs to be perceived, the network side directly determines which base stations and terminals to connect with. Using the network as an intermediary, the network directly collects the relevant perception data and returns it to the requesting AF. The above-mentioned embodiments of the present disclosure avoid the problem of requiring the AF to directly establish connections with base stations and terminals, and enable the network to more effectively manage related perception services, perception terminals, and base stations.

[0145] The above embodiments of the present disclosure provide a perception service design based on scenario-based perception terminals and perception base stations.

[0146] FIG4 is a schematic diagram of some other embodiments of the perception service method disclosed herein. Preferably, this embodiment can be performed by the core network device disclosed herein or the perception service system disclosed herein. FIG4 is a schematic diagram of some embodiments of the perception service method when it is judged to be a Class A scenario (i.e., a first type scenario, a full perception scenario). As shown in FIG4 , the method of the embodiment of FIG4 may include at least one step from step 1 to step 21, wherein:

[0147] In step 1, the Perception Service Application Function (AF) sends a perception data request to the Network Exposure Function (NEF) on the network side, reporting the perception scenario information and perception requirements. The perception scenario content is the spatial information of the scene to be perceived, including the center point location and corresponding length, width, height, or radius. The perception requirement is determined by the application function AF based on the actual perception service needs requested and reported to the network side.

[0148] Step 2: After receiving the sensing request, sensing scenario information, and sensing requirements, the network open function NEF forwards the request and related information to the network sensing function SF.

[0149] Step 3: After receiving the request, the perception scenario information, and the perception requirement, the network perception function SF creates a unique scenario ID for the perception scenario and matches the corresponding perception requirement with the scenario ID.

[0150] Step 4: After creating the scene ID, the perception function SF reports the scene information to the NRF for query, queries which specific base stations have perception capabilities in this scene, and requests the NRF to return the ID information of the relevant base stations.

[0151] Step 5: After receiving the request, the NRF queries for the relevant sensing-capable base stations and returns the ID information of all base stations with sensing capabilities in this scenario to the SF. After receiving the sensing-capable base station ID, the SF associates the scenario ID with the sensing-capable base station ID. Note: If the NRF query finds no sensing-capable base stations, it returns an empty request to the SF, informing it that there are no sensing-capable base stations in this scenario.

[0152] Step 6: After creating the scene ID, the perception function SF reports the scene information to the AMF to query the terminal information with perception capabilities. It queries which specific terminals with perception capabilities are in this scene and requests the AMF to return the ID information of the relevant terminals.

[0153] Step 7: After receiving the request, AMF queries the relevant perception-capable terminals and returns all the terminal ID information with perception capabilities in this scenario to SF. After receiving the perception-capable terminal ID, SF matches the scenario ID with the perception-capable terminal ID. Note: If there is no perception-capable terminal after the AMF query, an empty request is returned to SF to inform SF that there is no perception-capable terminal in this scenario.

[0154] Step 8: After receiving all the information from all the base stations and terminals with perception capabilities under this scene ID, the perception function SF determines which of the ABC scenes this perception scene belongs to, matches this scene ID with the scene classification, and then executes the relevant perception request operation according to the specific scene classification.

[0155] In the embodiment of FIG4 , step 8 may include: determining that the perception scenario is a Class A scenario (i.e., a first type scenario, a fully perceived scenario). When the perception scenario is determined to be a Class A scenario (i.e., a first type scenario, a fully perceived scenario), the perception service method of FIG4 may further include at least one of steps 9 to 21, wherein:

[0156] Step 9: The sensing function SF sends a request to the AMF, requesting all sensing-capable terminals in this scenario to access the network and establish connections with the sensing function SF. The request content includes the IDs of all sensing-capable terminals in the scenario ID.

[0157] Step 10: After receiving the SF's request, the Access and Mobility Management Function (AMF) sends a message to both the SF and the base station. It sends the terminal configuration information for all sensing-capable terminals in the scenario to the SF. It also sends a sensing-capable terminal access request to the base station, requesting the sensing-capable terminal to establish a connection with the SF via the base station.

[0158] Step 11: After receiving the request from the base station, the requested sensing capability terminal establishes a connection with the sensing function SF through the user plane function UPF of the core network.

[0159] Step 12: The sensing function SF sends a request to the NRF, requesting the NRF to issue the base station configuration information corresponding to the sensing capability. The request content is the IDs of all base stations with sensing capabilities corresponding to the scenario ID.

[0160] Step 13: After receiving the request, the network storage function NRF sends the relevant configuration information of the requested base station to the SF.

[0161] Step 14: After receiving the configuration information of the sensing capability base station, the network sensing capability SF directly sends a request to the corresponding base station, requesting the base station to respond and access the sensing function SF.

[0162] Step 15: After receiving the corresponding request, the base station directly accesses the sensing function SF through the interface between the base station and the sensing function SF.

[0163] In step 16, after all sensing capability base stations and sensing capability terminals in this scenario have established connections with SF, the sensing function SF simultaneously sends sensing operation requests to all sensing capability base stations and sensing capability terminals, requesting them to perform corresponding sensing operations and report sensing data.

[0164] Step 17: The sensing capability terminal completes the sensing operation.

[0165] Step 18: The sensing capability base station completes the sensing operation.

[0166] In step 19, after performing the sensing operation, the sensing terminal uploads the corresponding sensing data through the connection established between the UPF (User Plane Function) and the SF. During this process, the UPF will check the QoS related to the data and forward it to the SF.

[0167] Step 20: After performing the sensing operation, the sensing capability base station directly uploads the sensing data via the interface between the base station and the SF.

[0168] Step 21: After collecting all the sensing data, the sensing function SF processes the data in a relevant manner (security check, integrity check, classification, compression, etc.) and then forwards the data to the application function AF of the requesting party through the network opening function NEF.

[0169] Figure 5 is a schematic diagram of some other embodiments of the perception service method disclosed in the present invention. Preferably, this embodiment can be performed by the core network device disclosed in the present invention or the perception service system disclosed in the present invention. Figure 5 is a schematic diagram of some embodiments of the perception service method when it is judged to be a Class B scenario (i.e., the second type of scenario, the terminal perception scenario). Steps 1 to 8 of the embodiment of Figure 5 are the same as or similar to steps 1 to 8 of the embodiment of Figure 4. As shown in Figure 5, in addition to including at least one step from steps 1 to 8, the method of the embodiment of Figure 5 may also include at least one step from steps 51 to 57 when it is judged to be a Class B scenario (i.e., the second type of scenario, the terminal perception scenario) in step 8, wherein:

[0170] Step 51: The sensing function SF sends a request to the AMF, requesting all sensing-capable terminals in this scenario to access the network and establish connections with the sensing function SF. The request content includes the IDs of all sensing-capable terminals in the scenario ID.

[0171] Step 52: After receiving the SF's request, the Access and Mobility Management Function (AMF) sends a message to both the SF and the base station. It sends the terminal configuration information for all sensing-capable terminals in the scenario to the SF. It also sends a sensing-capable terminal access request to the base station, requesting the sensing-capable terminal to establish a connection with the SF via the base station.

[0172] Step 53: After receiving the request from the base station, the requested sensing capability terminal establishes a connection with the sensing function SF via the user plane function UPF of the core network.

[0173] In step 54, after all sensing capability terminals in this scenario have established connections with SF, the sensing function SF simultaneously sends sensing operation requests to all sensing capability terminals, requesting them to perform corresponding sensing operations and report sensing data.

[0174] Step 55: The sensing capability terminal completes the sensing operation.

[0175] Step 56: After performing the sensing operation, the sensing capability terminal uploads the corresponding sensing data through the connection established between the UPF and the SF. During this process, the UPF will check the QoS related to the data and forward it to the SF.

[0176] Step 57: After collecting all the sensing data, the sensing function SF processes the data in a relevant manner (security check, integrity check, classification, compression, etc.) and then forwards the data to the application function AF of the requesting party through the network opening function NEF.

[0177] Figure 6 is a schematic diagram of some further embodiments of the perception service method disclosed herein. Preferably, this embodiment can be performed by the core network device disclosed herein or the perception service system disclosed herein. Figure 6 is a schematic diagram of some embodiments of the perception service method when it is judged to be a Class C scenario (i.e., the third type of scenario, base station perception scenario). Steps 1 to 8 of the embodiment of Figure 6 are the same or similar to steps 1 to 8 of the embodiment of Figure 4 or Figure 5. As shown in Figure 6, in addition to including at least one step from steps 1 to 8, the method of the embodiment of Figure 6 may also include at least one step from steps 61 to 68 when it is judged to be a Class C scenario (i.e., the third type of scenario, base station perception scenario) in step 8, wherein:

[0178] Step 61: The sensing function SF sends a request to the NRF, requesting the NRF to issue the base station configuration information corresponding to the sensing capability. The request content is the IDs of all base stations with sensing capabilities corresponding to the scenario ID.

[0179] Step 62: After receiving the request, the network storage function NRF sends the requested base station configuration information to the SF.

[0180] Step 63: After receiving the configuration information of the sensing capability base station, the network sensing capability SF directly sends a request to the corresponding base station, requesting the base station to respond and access the sensing function SF.

[0181] Step 64: After receiving the corresponding request, the base station directly accesses the sensing function SF via the interface between the base station and the sensing function SF.

[0182] In step 65, after all sensing capability base stations in this scenario have established connections with SF, the sensing function SF simultaneously sends sensing operation requests to all sensing capability base stations, requesting them to perform corresponding sensing operations and report sensing data.

[0183] Step 66: The sensing capability base station completes the sensing operation.

[0184] Step 67: After performing the sensing operation, the sensing capability base station directly uploads the sensing data via the interface between the base station and the SF.

[0185] Step 68: After collecting all the sensing data, the sensing function SF performs relevant processing (security check, integrity check, classification, compression, etc.) and then forwards the data to the application function AF of the requester through the network opening function NEF.

[0186] In the traditional service model, a third-party AF directly establishes a connection and session with the corresponding terminal, after which the AF directly sends requests to the terminal and receives relevant data from the terminal. In the above-described embodiments of the present disclosure, to avoid excessive transmission load caused by directly transmitting large amounts of raw perception data through this connection and session, the terminal establishes a connection and session with the perception function SF, which then collects the relevant perception data, processes the data, and then forwards it to the AF.

[0187] Base station perception in network perception capability is a new service model. In the case of related technologies without terminal participation, since the specific configuration information of the base station is not open to the outside of the network, the third-party AF cannot directly request the relevant base station, and since the base station is not open to the outside, the third-party AF cannot directly establish a connection with the base station and send a session request to transmit data. Under the above embodiment of the present disclosure, first, through scenario-based request design, when it is impossible to directly request a specific perception capability base station, the network-side perception capability SF is responsible for determining the specific participating perception capability base station by describing the specific perception scenario. Secondly, by deploying the interface between the perception capability SF and the base station, the perception function SF can directly send a request to the base station and the base station can directly transmit data to the perception function SF.

[0188] Since perception capability terminals and perception capability base stations usually appear at the same time in actual perception scenarios, in order to allow two different types of devices to participate in the perception service at the same time and be effectively managed by the perception function SF. The above embodiment of the present disclosure proposes a scenario-based request and service model design, which is led by the network-side perception capability SF. According to the actual need to perform perception operations proposed by AF, SF simultaneously establishes all perception capability terminals and perception capability base stations in this scenario, and SF uniformly issues perception operation requests and collects relevant perception data. Finally, after unified processing of the perception data, it is reported to the requesting party AF at one time. At the same time, the above embodiment of the present disclosure avoids the problem of establishing a large number of sessions, the problem of excessive data transmission, and the problem of needing to manage perception capability terminals and base stations at the same time.

[0237] The sensing capability device is configured to perform a sensing operation after receiving a sensing request from a sensing function network element in the core network device, and then upload the received sensing data to the sensing function network element,

[0238] In some embodiments of the present disclosure, as shown in FIG. 9 and FIG. 4 to FIG. 6 , the sensing capability device includes at least one of a sensing capability terminal (Sensing UE) 97 and a sensing capability base station (Sensing Base Station, RAN) 98 .

[0240] In some embodiments of the present disclosure, the sensing object 90 may be a sensing target such as a vehicle or a person.

[0241] In some embodiments of the present disclosure, the sensing object 90 may be a sensing parameter in a sensing scene, such as temperature and humidity.

[0242] In some embodiments of the present disclosure, as shown in FIG9 , the sensing capability device may further include an Assistant Sensing UE 99, wherein:

[0243] The auxiliary sensing capability terminal 99 is configured to forward a request from the base station to the sensing capability terminal and forward sensing data from the sensing capability terminal to the base station when the base station cannot directly connect to the sensing capability terminal.

[0245] In some embodiments of the present disclosure, the auxiliary sensing capability terminal 99 is only responsible for forwarding the data of the Sensing UE to the base station based on the Sidelink when the base station cannot directly connect to the Sensing UE.

[0246] In order to enable the third-party AF to more effectively initiate requests for sensing services, and to enable base stations and terminals with sensing capabilities to cooperate to perform related sensing operations and transmit sensing data. The above-mentioned embodiment of the present disclosure is based on the sensing function network element (Sensing Function) deployed on the core network side as the core, through the interface between the sensing function network element SF and the base station, the interface between the sensing function network element SF and the access and mobility management function network element (AMF), and the interface between the sensing function network element SF and the user plane function (UPF), so that the sensing function SF can effectively establish connections with the sensing-capable base station and the sensing-capable terminal at the same time and transmit related requests and data.

[0247] In addition, in order to better enable the third-party AF to obtain data from the perception capability terminal and the perception capability base station. The above embodiment of the present disclosure designs a scene-based perception service request mode, that is, the AF only needs to accurately describe the scene location information and spatial information of the required perception scene, as well as the perception data level requirements required by the AF and report them to the perception function SF on the network side. The perception function SF will directly assign an exclusive perception scene ID to the scene of this perception service. The perception function SF will then directly request the information of the relevant perception capability terminal and perception capability base station based on the scene information. The perception function SF will then determine which category the perception scene requested from the AF belongs to, and send a perception operation request to all perception capability terminals and base stations in this scene, requesting all perception capability base stations and terminals to perform relevant perception operations and upload relevant perception data. Finally, the perception data will be processed accordingly and returned to the requesting AF.

[0248] In summary, the above embodiments of the present disclosure, based on the interface between the network perception function SF and other functional units and base stations on the core network side, as well as the scenario-based service request specifications, not only enable the network to more effectively manage base stations and terminals with perception capabilities in perception services, but also solve the problem that the AF cannot directly establish a connection with the base station, send perception requests to the base station and receive perception data because the base station information is not open to third parties. Moreover, the AF does not need to establish a connection with all terminals or base stations involved in the perception operation, and can directly receive perception data from the perception function SF to meet the perception service needs, and avoids the problem of excessive transmission load caused by directly transmitting the original data.

[0249] According to another aspect of the present disclosure, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores computer instructions, and when the instructions are executed by a processor, the perception service method as described in any of the above embodiments (any of Figures 1 and 4 to 6) is implemented.

[0250] In some embodiments of the present disclosure, the computer-readable storage medium may be a non-transitory computer-readable storage medium.

[0251] In the future, in businesses that require the deployment of actual network perception capabilities, the scenario-based management service design proposed in the above-mentioned embodiments of this disclosure can be deployed. That is, when deploying macro-network perception capabilities, considering that the actual business will cover smart city scenarios such as roads, schools, hospitals, and outdoor non-urban scenarios such as farms, as well as indoor scenarios, the scenario-based service model designed in the above-mentioned embodiments of this disclosure can achieve flexible execution of perception services by flexibly defining the spatial information of the scene, the size of the actual perception scene, and the coordination of large and small base stations and perception terminals. At the same time, it can be universally deployed in different scenarios, so that network perception capabilities can cover more actual scenarios and needs.

[0252] The scenario-based perception service model proposed in the above embodiments of the present disclosure can not only be universally deployed in different perception scenarios, allowing network perception capabilities to cover more practical scenarios, but also provide diversified services for more perception-related application functions (AF). The above embodiments of the present disclosure can help operators discover more potential customers who need perception services when network perception capabilities are actually deployed in the future.

[0253] The above embodiments of the present disclosure are designed based on network awareness function network elements deployed in the core network.
