[0002] In the research related to network sensing capabilities, due to the consideration that some base stations need to have sensing capabilities, different situations will occur in actual sensing scenarios, that is, there are base stations and terminals with sensing capabilities, as well as only terminals or base stations with sensing capabilities. Summary of the Invention

[0003] The inventors found through research that: in the related art, although the base station has the ability to provide sensing services, it cannot open relevant configuration information to a third-party AF (Application Function) server like a terminal, and the third-party AF server cannot establish a direct connection with the base station by reporting an ID in the same way as connecting to a terminal.

[0082] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a 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 in no way constitutes a limitation on the present disclosure and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0083] Unless otherwise specifically stated, the relative arrangements, numerical expressions and values of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0084] At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0085] For technologies, methods and devices known to those of ordinary skill in the relevant art, they may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the authorization specification.

[0086] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0087] It should be noted that: like reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0088] The inventor found through research that in the related technology perception service, since the 3GPP SA1 requirement specification for network perception capabilities includes both perception services based on terminal perception capabilities and perception services based on base station perception capabilities. In the mode based on terminal perception capabilities, a third-party AF can obtain terminal-related information, and establish a relevant connection with the corresponding terminal by reporting the terminal ID to the network and directly transmit data.

[0089] However, in the mode based on base station perception capabilities in the related technology, since the base station information is not open to the third-party AF, the third-party AF cannot describe the relevant perception service requirements by reporting the base station ID, and the base station cannot directly establish a connection with the AF and transmit data. At the same time, due to the extremely large amount of perception data in the perception service, in order to avoid excessive network load caused by a large amount of transmission of raw perception data is also a difficulty in the related technology network perception service.

[0090] In order to enable the third-party AF to more effectively initiate a request for a perception service, and enable the base station and terminal with perception capabilities to cooperate to perform relevant 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. The present disclosure will be described below through specific embodiments.

[0091] Figure 1 It is a schematic diagram of some embodiments of the perception service method of the present disclosure. Preferably, this embodiment can be executed by the SF (Sensing Function) of the present disclosure, or a core network device, or the perception service system of the present disclosure. As Figure 1 shown, Figure 1 The method of the embodiment may include at least one of step 100, step 300 to step 500, where:

[0092] Step 100, the perception function network element receives a perception data request sent by the application function server, where the perception data request includes perception scenario information.

[0093] In some embodiments of the present disclosure, the perception scenario information is the spatial information of the scenario to be perceived, including the center point position information and corresponding length, width, height or radius and other information.

[0094] In some embodiments of the present disclosure, the perception data request may further include a perception requirement, the perception scenario content is the spatial information of the scenario to be perceived, and the perception requirement is determined by the application function server according to the actual requested perception service needs and reported to the network side.

[0095] In some embodiments of the present disclosure, step 100 may include: the sensing function network element receives the sensing data request forwarded by the application function server through the NEF (Network Exposure Function).

[0096] In some embodiments of the present disclosure, step 100 may include: the sensing service application function AF sends a sensing data request to the network exposure function NEF on the network side, and reports the sensing scenario information and sensing requirements. The content of the sensing scenario is the spatial information of the scenario to be sensed, including the center point location information and corresponding length, width, height or radius and other information. The sensing requirement is determined by the application function AF according to the actual sensing service request and reported to the network side; after receiving the sensing request, sensing scenario information and sensing requirements, the network exposure function NEF forwards this request and related information to the network sensing function SF.

[0097] In some embodiments of the present disclosure, the third-party AF determines the relevant sensing scenarios and sensing requirements according to the actual sensing service needs. Among them, the sensing scenario is determined by the AF itself. The scenario is a three-dimensional space, including the position of the center point and data such as length, width, height or radius based on the center point to describe the spatial information of the scenario. The sensing requirements include sensing operations and sensing data, which are specific requirement information related to the sensing service.

[0098] Figure 2 It is a schematic diagram of the sensing scenario in some embodiments of the present disclosure. As Figure 2 shown, each dotted circle represents a sensing scenario defined by an AF according to the actual sensing service requirements. Since the AF cannot determine whether there are specific base stations or which base stations have sensing capabilities to obtain sensing data in the scenario, the AF only needs to report the position information and spatial information of the requested sensing scenario and the corresponding sensing requirements to the network. The specific sensing-capable base stations and sensing-capable terminals in the scenario and the sensing capabilities they possess are all determined by the network side.

[0099] In some embodiments of the present disclosure, the sensing service method of the present disclosure may further include step 200, where:

[0100] Step 200, the sensing function network element assigns a dedicated scenario identifier to the sensing scenario information.

[0105] In some embodiments of the present disclosure, the sensing-capable terminal may be a network access side device such as a Wireless Access Point (AP), a router, a switch, etc.

[0106] In some embodiments of the present disclosure, step 300 may include: the sensing function network element reports the sensing scenario information to the NRF (Network Repository Function), queries the base stations with sensing capabilities under the sensing scenario information; the sensing function network element receives the identification information of all the base stations with sensing capabilities under the sensing scenario information returned by the network repository function network element.

[0107] In some embodiments of the present disclosure, step 300 may include: after creating the scenario ID, the Sensing Function (SF) reports the scenario information to the NRF for querying, queries which specific base stations with sensing capabilities exist in this scenario, requests the NRF to return the ID information of the relevant base stations; after receiving the request, the NRF queries the relevant sensing-capable base stations and returns all the ID information of the base stations with sensing capabilities in this scenario to the SF, and the SF associates the scenario ID with the ID of the sensing-capable base stations after receiving the ID of the sensing-capable base stations.

[0108] In some embodiments of the present disclosure, if the NRF does not find any sensing-capable base stations after querying, it returns an empty request to the SF, informing the SF that there are no sensing-capable base stations in this scenario.

[0109] In some embodiments of the present disclosure, step 300 may include: the sensing function network element reports the sensing scenario information to the AMF (Access and Mobility Management Function), queries the terminals with sensing capabilities under the sensing scenario information; the sensing function network element receives the identification information of all the terminals with sensing capabilities under the sensing scenario information returned by the access and mobility management function network element.

[0110] In some embodiments of the present disclosure, step 300 may include: after the sensing function SF creates the scene ID, it reports the scene information to the AMF to query the information of the terminals with sensing capabilities. Query which specific terminals with sensing capabilities exist in this scene, and request the AMF to return the ID information of the relevant terminals; after receiving the request, the AMF queries the relevant terminals with sensing capabilities and returns all the ID information of the terminals with sensing capabilities in this scene to the SF. After receiving the ID of the terminal with sensing capabilities, the SF associates the scene ID with the ID of the terminal with sensing capabilities.

[0111] In some embodiments of the present disclosure, if there are no terminals with sensing capabilities after the AMF queries, it returns an empty request to the SF, informing the SF that there are no terminals with sensing capabilities in this scene.

[0112] Step 400, the sensing function network element determines the scene classification of the sensing scene according to the sensing-capable devices existing in the sensing scene.

[0113] In some embodiments of the present disclosure, step 400 may include at least one of steps 410 to 430, where:

[0114] Step 410, the sensing function network element queries the base station and terminal configuration information. If it is determined that there are both a sensing-capable base station and a sensing-capable terminal in the sensing scene, it determines that the scene classification of the sensing scene is the first type of scene (Scene A, full sensing scene).

[0115] Step 420, the sensing function network element queries the base station and terminal configuration information. If it is determined that there is a sensing-capable terminal in the sensing scene and there is no sensing-capable base station, it determines that the scene classification of the sensing scene is the second type of scene (Scene B, terminal sensing scene).

[0116] Step 430, the sensing function network element queries the base station and terminal configuration information. If it is determined that there is no sensing-capable terminal in the sensing scene and there is a sensing-capable base station, it determines that the scene classification of the sensing scene is the third type of scene (Scene C, base station sensing scene).

[0117] Figure 3 It is a schematic diagram of the sensing scene classification in some embodiments of the present disclosure. As Figure 3 shown, the full sensing scene is specifically: in the scene provided by the AF, the sensing function network element SF discovers that there are both a sensing-capable base station and a sensing-capable terminal in this scene after querying the base station and terminal configuration information. As Figure 3 shown in Scene A.

[0118] The specific terminal perception scenario is as follows: within the scenario provided by the AF, after the sensing function network element SF queries the base station and terminal configuration information, it is found that there are only sensing-capable terminals and no sensing-capable base stations in this scenario. For example, Figure 3 as shown in Scenario B.

[0119] The specific base station perception scenario is as follows: within the scenario provided by the AF, after the sensing function network element SF queries the base station and terminal configuration information, it is found that there are only sensing-capable base stations and no sensing-capable terminals in this scenario. For example, Figure 3 as shown in Scenario C.

[0120] Step 500, the sensing function network element performs relevant sensing request operations according to the scenario classification of the sensing scenario.

[0121] In some embodiments of the present disclosure, steps 400 to 500 may include: after the sensing function SF receives all the information of all the base stations and terminals with sensing capabilities under this scenario ID, it determines which scenario among A, B, and C this sensing scenario belongs to, associates this scenario ID with the scenario classification, and then performs relevant sensing request operations according to the specific scenario classification.

[0122] In some embodiments of the present disclosure, step 500 may include: the sensing function network element SF can perform different operations after receiving the scenario allocation ID reported by the AF and confirming the classification.

[0123] In some embodiments of the present disclosure, step 500 may include at least one of steps 510 to 550, where:

[0126] Step 520, the sensing function network element requests the sensing-capable devices to access the sensing function network element.

[0127] In some embodiments of the present disclosure, when the scenario classification of the sensing scenario is the first type of scenario or the second type of scenario, step 520 may include: the sensing function network element sends an access request to the access and mobility management function network element, requesting all sensing-capable terminals in the sensing scenario to access the network and establish a connection with the sensing function network element; the sensing function network element receives the terminal configuration information of all sensing-capable terminals in the sensing 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 sensing function network element, and at the same time sends a sensing-capable terminal access request to the sensing-capable terminal through the base station, requesting the sensing-capable terminal to establish a connection with the sensing function network element through the user plane function network element.

[0128] In some embodiments of the present disclosure, when the scenario classification of the sensing scenario is the first type of scenario or the third type of scenario, step 520 may include: the sensing function network element sends an access request to the network repository function network element, requesting the network repository function network element to issue the configuration information of the corresponding sensing-capable base station; after receiving the configuration information of the sensing-capable base station, the sensing-capability network element directly sends a base station access request to the corresponding sensing-capable base station, requesting the sensing-capable base station to respond and access the sensing-capability network element.

The above embodiments of the present disclosure avoid the problem that the AF needs to directly establish connections with the base stations and terminals, and enable the network to more effectively manage relevant sensing services, sensing terminals, and base stations.

[0134] The above embodiments of the present disclosure provide a perception service design for a perception terminal and a perception base station based on scenarios.

[0135] Figure 4 It is a schematic diagram of some other embodiments of the perception service method of the present disclosure. Preferably, this embodiment can be executed by the core network device of the present disclosure or the perception service system of the present disclosure. Figure 4 It is a schematic diagram of some embodiments of the perception service method in the case of being determined as a type A scenario (i.e., the first type of scenario, the full perception scenario). As Figure 4 shown, Figure 4 The method of the embodiment may include at least one of steps 1 to 21, where:

[0136] Step 1, the perception service application function AF sends a perception data request to the network exposure function NEF on the network side, and reports the perception scenario information and perception requirements. The perception scenario content is the spatial information of the scenario to be perceived, including the center point location information and corresponding length, width, height or radius and other information. The perception requirement is determined by the application function AF according to the actual requested perception service needs and reported to the network side.

[0137] Step 2, after receiving the perception request, perception scenario information and perception requirements, the network exposure function NEF forwards this request and related information to the network perception function SF.

[0138] Step 3, after receiving the request, perception scenario information and perception requirements, the network perception function SF creates a dedicated scenario ID for this perception scenario, and associates the corresponding perception requirements with the scenario ID.

[0139] Step 4, after creating the scenario ID, the perception function SF reports the scenario information to the NRF for querying which specific base stations with perception capabilities exist in this scenario, and requests the NRF to return the ID information of relevant base stations.

[0140] Step 5, after receiving the request, the NRF queries relevant base stations with perception capabilities, and returns all the ID information of all base stations with perception capabilities in this scenario to the SF. After receiving the ID of the base station with perception capabilities, the SF associates the scenario ID with the ID of the base station with perception capabilities. Note: If the NRF does not find a base station with perception capabilities after querying, it returns an empty request to the SF, informing the SF that there is no base station with perception capabilities in this scenario.

[0141] Step 6, 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. Query which specific terminals with perception capabilities exist in this scenario, and request the AMF to return the ID information of relevant terminals.

[0142] Step 7: After receiving the request, the AMF queries the relevant sensing-capable terminals and returns all the terminal ID information of the terminals with sensing capabilities in this scenario to the SF. After receiving the sensing-capable terminal IDs, the SF associates the scenario ID with the sensing-capable terminal IDs. Note: If there are no sensing-capable terminals after the AMF's query, an empty request is returned to the SF, informing the SF that there are no sensing-capable terminals in this scenario.

[0143] Step 8: After receiving all the information of the base stations and terminals with sensing capabilities in this scenario ID, the sensing function SF determines which type of scenario among A, B, and C this sensing scenario belongs to, associates this scenario ID with the scenario classification, and then performs relevant sensing request operations according to the specific scenario classification.

[0144] In Figure 4 the embodiment, Step 8 may include: determining that the sensing scenario is a type-A scenario (i.e., the first type of scenario, the full-sensing scenario). In the case of determining that it is a type-A scenario (i.e., the first type of scenario, the full-sensing scenario), Figure 4 the sensing service method may further include at least one step from Step 9 to Step 21, where:

[0145] Step 9: The sensing function SF sends a request to the AMF, requesting all the sensing-capable terminals in this scenario to access the network and establish a connection with the sensing function SF. The request content includes all the sensing-capable terminal IDs under the scenario ID.

[0146] Step 10: After receiving the request from the SF, the access and mobility management function AMF sends messages to both the SF and the base station simultaneously. It sends the terminal configuration information of all the sensing-capable terminals in the scenario to the SF. It sends a sensing-capable terminal access request to the base station, requesting the sensing-capable terminal to establish a connection with the SF through the base station.

[0147] Step 11: After receiving the request from the base station, the requested sensing-capable terminal establishes a connection with the sensing function SF through the user plane function UPF of the core network.

[0148] 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 capabilities. The request content is the IDs of all the base stations with sensing capabilities corresponding to the scenario ID.

[0149] Step 13: After receiving the request, the network storage function NRF issues the relevant configuration information of the requested base station to the SF.

[0150] Step 14: After receiving the configuration information of the sensing-capable base station, the network sensing function SF directly sends a request to the corresponding base station, requesting the base station to respond and access the sensing function SF.

[0151] 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.

[0152] Step 16, in this scenario, after all the sensing capabilities of the base station and the sensing capabilities of the terminal are connected to the SF, the sensing function SF simultaneously sends sensing operation requests to all the sensing-capable base stations and sensing-capable terminals, requesting them to perform corresponding sensing operations and report sensing data.

[0153] Step 17, the sensing-capable terminal completes the sensing operation.

[0154] Step 18, the sensing-capable base station completes the sensing operation.

[0155] Step 19, after completing the sensing operation, the sensing-capable terminal uploads the corresponding sensing data through the connection established with the SF via the UPF (User Plane Function). The UPF will check the QoS related to the data during this process and forward it to the SF.

[0156] Step 20, after completing the sensing operation, the sensing-capable base station directly uploads the sensing data through the interface between the base station and the SF.

[0157] Step 21, after collecting all the sensing data, the sensing function SF forwards the data to the application function AF of the requester through the network exposure function NEF after relevant processing (such as security check, integrity check, classification, compression, etc.).

[0158] Figure 5 It is a schematic diagram of some other embodiments of the sensing service method of the present disclosure. Preferably, this embodiment can be executed by the core network device of the present disclosure or the sensing service system of the present disclosure. Figure 5 It is a schematic diagram of some embodiments of the sensing service method in the case of being determined as a Class B scenario (i.e., the second type of scenario, the terminal sensing scenario). Figure 5 Steps 1 to 8 of the embodiment are the same as or similar to Figure 4 Steps 1 to 8 of the embodiment. As Figure 5 shown, Figure 5 In addition to including at least one of Steps 1 to 8 of the embodiment, in the case where it is determined as a Class B scenario (i.e., the second type of scenario, the terminal sensing scenario) in Step 8, the sensing service method may further include at least one of Steps 51 to 57, where:

[0159] Step 51, the sensing function SF sends a request to the AMF, requesting all the sensing-capable terminals in this scenario to access the network and establish a connection with the sensing function SF. The request content includes all the sensing-capable terminal IDs under the scenario ID.

[0160] Step 52, after receiving the request from the SF, the Access and Mobility Management Function (AMF) sends messages to both the SF and the base station simultaneously. It sends the terminal configuration information of all the sensing-capable terminals in the scenario to the SF. It sends a request for the access of the sensing-capable terminals to the base station, requesting the sensing-capable terminals to establish a connection with the SF through the base station.

[0161] Step 53, after receiving the request from the base station, the requested sensing-capable terminal establishes a connection with the Sensing Function (SF) through the User Plane Function (UPF) of the core network.

[0162] Step 54, after all the sensing-capable terminals in this scenario have established connections with the SF, the Sensing Function (SF) simultaneously sends sensing operation requests to all the sensing-capable terminals, requesting them to perform corresponding sensing operations and report sensing data.

[0163] Step 55, the sensing-capable terminal completes the sensing operation.

[0164] Step 56, after completing the sensing operation, the sensing-capable terminal uploads the corresponding sensing data through the connection established with the SF via the UPF. The UPF will check the QoS related to the data during this process and forward it to the SF.

[0165] Step 57, after collecting all the sensing data, the Sensing Function (SF) forwards the data to the Application Function (AF) of the requesting party through the Network Exposure Function (NEF) after relevant processing (such as security check, integrity check, classification, compression, etc.).

[0166] Figure 6 It is a schematic diagram of some embodiments of the sensing service method of the present disclosure. Preferably, this embodiment can be executed by the core network device of the present disclosure or the sensing service system of the present disclosure. Figure 6 It is a schematic diagram of some embodiments of the sensing service method in the case of being determined as a Class C scenario (i.e., the third type of scenario, base station sensing scenario). Figure 6 Steps 1 to 8 of the embodiment are the same as or similar to Figure 4 or Figure 5 Steps 1 to 8 of the embodiment are the same or similar. As Figure 6 shown, Figure 6 In addition to including at least one of Steps 1 to 8 of the embodiment, in the case of being determined as a Class C scenario (i.e., the third type of scenario, base station sensing scenario) in Step 8, the sensing service method may further include at least one of Steps 61 to 68, where:

[0167] 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 capabilities. The request content is the IDs of all the base stations with sensing capabilities corresponding to the scenario ID.

[0168] Step 62, after receiving the request, the Network Storage Function (NRF) sends the relevant configuration information of the requested base station to the SF.

[0169] Step 63, after receiving the configuration information of the sensing-capable base station, the Network Sensing Function (SF) directly sends a request to the corresponding base station, requesting the base station to respond and connect to the sensing function SF.

[0170] Step 64, after receiving the corresponding request, the base station directly connects to the sensing function SF through the interface between the base station and the sensing function SF.

[0171] Step 65, in this scenario, after all the sensing-capable base stations have established connections with the SF, the sensing function SF simultaneously sends sensing operation requests to all the sensing-capable base stations, requesting them to perform the corresponding sensing operations and report the sensing data.

[0172] Step 66, the sensing-capable base station completes the sensing operation.

[0173] Step 67, after completing the sensing operation, the sensing-capable base station directly uploads the sensing data through the interface between the base station and the SF.

[0174] Step 68, after collecting all the sensing data, the sensing function SF forwards the data to the Application Function (AF) of the requesting party through the Network Exposure Function (NEF) after relevant processing (such as security check, integrity check, classification, compression, etc.).

[0175] In the traditional service model of related technologies, a third-party AF directly establishes a connection and session with the corresponding terminal, and then the AF directly sends a request to the terminal and directly receives the relevant data from the terminal. In the above embodiments of the present disclosure, in order to avoid excessive transmission load caused by directly transmitting a large amount of raw sensing data in this connection and session, after establishing a connection and session between the terminal and the sensing function SF, the sensing function SF collects the relevant sensing data, processes the data, and then forwards it to the AF.

[0176] Base station sensing in network sensing capabilities is a new service model. In related technologies, without the participation of the terminal, since the specific configuration information of the base station is not open to the outside of the network, a 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 also cannot directly establish a connection and session with the base station to send requests and transmit data. In the above embodiments of the present disclosure, first, through a scenario-based request design, in the case where the specific sensing-capable base station cannot be directly requested, the specific sensing scenario is described to let the network-side sensing function SF be responsible for determining the specific participating sensing-capable base stations. Second, by deploying the interface between the sensing function SF and the base station, the sensing function SF can directly send requests to the base station and the base station can directly transmit data to the sensing function SF.

[0177] Since in an actual sensing scenario, sensing capability terminals and sensing capability base stations usually appear simultaneously, in order to enable two different types of devices to participate in the sensing service simultaneously and be effectively managed by the sensing function SF. The above embodiments of the present disclosure propose a scenario-based request and service mode design, which is led by the network-side sensing function SF. Under the scenario where the SF performs sensing operations according to the actual needs proposed by the AF, the SF simultaneously establishes all the sensing capability terminals and sensing capability base stations in this scenario, and the SF uniformly issues sensing operation requests and collects relevant sensing data. Finally, after uniformly processing the sensing data, it is reported to the requesting party AF at one time. At the same time, the above embodiments of the present disclosure avoid the problems of establishing a large number of sessions, excessive transmission data volume, and the need to manage sensing capability terminals and base stations simultaneously.

Figures 4 to 6 Schematic diagrams of some embodiments of the sensing service system of the present disclosure are also given. As Figure 9 , Figures 4 to 6 shown, the sensing service system of the present disclosure may include core network devices as described in any of the above embodiments.

[0226] In some embodiments of the present disclosure, as Figure 9 , Figures 4 to 6 shown, the sensing capability device includes at least one of a Sensing User Equipment (Sensing UE) 97 and a Sensing Base Station (RAN) 98.

[0227] In some embodiments of the present disclosure, as Figure 9 , Figures 4 to 6 shown, the Sensing UE 97 or the Sensing Base Station 98 performs a sensing operation to obtain sensing data from a sensing object 90.

[0234] In order to enable the third-party AF to initiate requests for sensing services more effectively and enable the base stations and terminals with sensing capabilities to cooperate in performing relevant sensing operations and transmitting sensing data. The above embodiments of the present disclosure are centered around the sensing function network element (Sensing Function) deployed on the core network side. Through the interfaces between the sensing function network element SF and the base station, the sensing function network element SF and the access and mobility management function network element (AMF), and the sensing function network element SF and the user plane function (UPF), the sensing function SF can effectively establish connections with both the sensing-capable base stations and the sensing-capable terminals and transmit relevant requests and data.

[0235] In addition, in order to better enable the third-party AF to obtain data from the sensing-capable terminals and sensing-capable base stations. The above embodiments of the present disclosure design a scenario-based sensing service request mode, that is, the AF only needs to accurately describe the scene location information and spatial information of the required sensing scene, as well as the requirements at the sensing data level required by the AF and report them to the sensing function SF on the network side. The sensing function SF will directly assign a dedicated sensing scene ID to the scene of this sensing service. Then, the sensing function SF will directly request information from the relevant sensing-capable terminals and sensing-capable base stations according to the scene information. Then, the sensing function SF will determine which type of scene the sensing scene requested by the AF belongs to and send a sensing operation request to all the sensing-capable terminals and base stations in this scene, requesting all the sensing-capable base stations and terminals to perform relevant sensing operations and upload relevant sensing data. Finally, the sensing data is processed accordingly and returned to the requesting party AF.

[0236] In summary, based on the interfaces between the network awareness function SF and other functional units on the core network side and the base stations, as well as the service request specifications designed for scenarios, the above embodiments of the present disclosure not only enable the network to more effectively manage base stations and terminals with awareness capabilities in awareness services, but also solve the problem that the AF cannot directly establish a connection with the base station, send an awareness request to the base station, and collect awareness data due to the non-disclosure of base station information to third parties. Moreover, the AF does not need to establish a connection with all terminals or base stations participating in the awareness operation, and can directly collect awareness data from the awareness function SF to meet the requirements of awareness services, and also avoid the problem of excessive transmission load caused by directly transmitting raw data.

[0237] According to another aspect of the present disclosure, there is provided a computer-readable storage medium, wherein the computer-readable storage medium stores computer instructions, and when the instructions are executed by a processor, the awareness service method as described in any of the above embodiments ( Figure 1 、 Figures 4 to 6 any of the above embodiments) is implemented.

[0238] In some embodiments of the present disclosure, the computer-readable storage medium may be a non-transitory computer-readable storage medium.

[0239] In the future, in services that require the deployment of actual network awareness capabilities, the scenario-based management service design proposed in the above embodiments of the present disclosure can be deployed. That is, when deploying the macroscopic network awareness capabilities, considering that actual services will cover smart city scenarios such as roads, schools, hospitals, outdoor non-urban scenarios such as farms, and indoor scenarios, etc., the scenario-based service mode designed in the above embodiments of the present disclosure can flexibly define the spatial information of the scenario, the size of the actual awareness scenario, and the cooperation of large and small base stations and awareness terminals, so as to flexibly execute awareness services and can also be generally deployed in different scenarios, enabling the network awareness capabilities to cover more actual scenarios and requirements.

[0240] The scenario-based awareness service mode proposed in the above embodiments of the present disclosure can not only be generally deployed in different awareness scenarios, enabling the network awareness capabilities to cover more actual scenarios, but also provide diverse services for more application functions AF related to awareness services. The above embodiments of the present disclosure can explore more potential customers in need of awareness services for operators when actually deploying network awareness capabilities in the future.

[0241] The above embodiments of the present disclosure are designed based on the network awareness functional network element deployed on the core network.

[0242] The above embodiments of the present disclosure deploy four interfaces based on the core network awareness function network element, namely, "the awareness function network element SF and the access and mobility management function network element AMF", "the awareness function network element SF and the user plane function network element UPF", "the awareness function network element SF and the network storage function network element NRF", "the awareness function network element SF and the network exposure function network element NEF", and "the awareness function network element SF and the base station RAN".

[0243] The awareness function network element SF of the above embodiments of the present disclosure mainly has the following three functions: 1. Allocate a dedicated scenario ID for the scenario information reported by the application function network element AF, and confirm the corresponding awareness base station and awareness terminal in this scenario; 2.
