[0003] This disclosure relates to the field of communication technology, and in particular to a sensing service processing method and computer program product. Background Technology

[0004] With the evolution of communication technology, communication frequency bands, especially millimeter-wave bands, have evolved to include sensing capabilities. When wireless access network elements or terminal devices possess sensing capabilities, they can perceive and identify specific areas, objects, or events. Currently, the International Mobile Telecommunications (IMT) 2020 standard provides a sensing infrastructure and basic implementation process. In actual sensing service scenarios, considering the security requirements of network-side data, application function network elements typically initiate sensing requests based on perceived geographical / administrative regions. However, the implementation of sensing services requires mapping from perceived geographical / administrative regions to network-side location information for network element discovery and other needs. Currently, in the sensing infrastructure, the network repository function network element is mainly responsible for registering network element sensing capabilities, which does not meet the positioning requirements of mapping geographical / administrative regions to network-side location information. Therefore, how to implement sensing service processing is a problem that urgently needs to be solved. Summary of the Invention

[0078] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0079] Please refer to Figure 1. A first aspect of this disclosure provides a method for processing perceived services, including the following steps S11 to S13:

[0080] Step S11: Receive a first sensing request; wherein the first sensing request is used to initiate a sensing service, and the first sensing request includes sensing request area information and its corresponding network-side location information; the network-side location information is obtained by a pre-configured sensing storage function network element based on the sensing request area information and / or the type of the sensing service;

[0081] Step S12: Send a second sensing request to the target sensing base station based on the network-side location information; wherein the second sensing request is used to instruct the target sensing base station to start a sensing task.

[0082] The method further includes:

[0083] Step S13: Receive sensing data sent by the target sensing base station.

[0084] Specifically, the perception service processing method provided in this embodiment is executed by a perception network element or a perception control plane function network element. The perception network element is a perception function node in a non-control and user plane (C / U) separation architecture scenario; the perception control plane function network element is a perception function control plane node in a C / U separation architecture; and the perception user plane function network element is a perception function user plane node in a C / U separation architecture, thereby meeting the perception service processing requirements under different deployment architectures. To enable the mapping of perceived geographic / administrative regions to network-side location information for network element discovery and other needs, this embodiment adds a Sensing Repository Function (SRF) network element. This SRF network element maps the perceived request area information (latitude, longitude, grid, 3D coordinates, etc.) from sensing requesters such as application function network elements, internal network elements, and user equipment (UE) to obtain corresponding network-side location information. By adding this SRF network element, it is possible to map geographic regions provided by applications to network-side location data (such as provinces and Tracking Area Identity (TAI) supported by existing network element discovery). This avoids the need for other technical solutions to store complex and potentially dynamically updated perceived area information such as latitude and longitude using network repository function network elements (such as Network Repository Function (NRF) nodes). This reduces the functional complexity of the network repository function network element used for network element registration and discovery, and enables the coordinated storage, processing, and retrieval of all sensing capabilities, regions, and results data through a unified sensing storage function, resulting in a clearer and simpler business process. Specifically, in this embodiment, upon receiving a first sensing request, a sensing service is initiated in response to the first sensing request. Based on the network-side location information carried in the first sensing request, the target sensing base station to be performing the sensing task can be identified, and a second sensing request is sent to the target sensing base station. It is worth noting that the second sensing request includes the sensing request area information and its corresponding network-side location information, as well as corresponding data reporting sensing network element / sensing user plane function network element information, sensing requester information (optional), and sensing service identifier information; wherein, the sensing requester information and sensing service identifier information are sent by the sensing requester together when initiating the sensing service request. The second sensing request instructs the target sensing base station to initiate the sensing task, that is, to complete the sensing detection and sensing data acquisition, and then receives the sensing data fed back by the target sensing base station. It is worth noting that the SRF network element in this embodiment can be set up independently as a node, or it can be co-located with other nodes such as sensing network elements / sensing control plane function network elements. This embodiment does not specifically limit the deployment method of the SRF network element.

[0085] As an optional solution, receiving the first sensing request specifically includes:

[0086] The system can receive a first sensing request from any application function network element or internal network element within the sensing capability open function network element; or, directly receive the first sensing request from any internal network element; or, receive the first sensing request from any user equipment (UE) within the access and mobility management function network element. It is worth noting that for sensing service requests initiated by application function network elements, the aforementioned first sensing request needs to be sent through the sensing capability open function network element. If the sensing service request is initiated by an internal network element, it can be determined whether it needs to go through the sensing capability open function network element based on the type and requirements of the initiating network element. If it does not need to go through the sensing capability open function network element, the internal network element can directly send the first sensing request after receiving the network-side location information fed back by the SRF network element. For the UE, it needs to first initiate a sensing service request to its affiliated access and mobility management function network element through the base station, and then the access and mobility management function network element sends the first sensing request after receiving the network-side location information fed back by the SRF network element.

[0087] As an optional solution, the sensing storage function network element is used to store sensing capability information and sensing area information of different network elements; when a location information query request is received, based on the sensing capability information corresponding to each of the stored sensing area information, the sensing request area information carried in the location information query request is mapped to the corresponding network-side location information, and fed back to the query requesting party that sent the location information query request; wherein, the query requesting party is the sensing capability opening function network element, the access and mobility management function network element, or the network internal network element; the sensing capability information includes at least one of sensing base station information, sensing cell information, tracking area identifier, province / region information, supported sensing services, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information.

[0088] Specifically, in order to facilitate unified management and retrieval of data, the SRF network element in this embodiment is used to uniformly store sensing capability information and sensing area information, and convert the stored sensing capability information and sensing area information into structured data according to a preset format, supporting unified retrieval by other peripheral nodes such as sensing capability open function network elements. Understandably, when any application function network element or internal network element initiates a sensing service request to the sensing capability open function network element, the sensing capability open function network element will initiate a location information query request to the SRF network element. This location information query request carries the sensing request area information of the sensing requester, and the SRF network element responds to this location information query request by performing network-side location information mapping. When any internal network element does not need to initiate a sensing service through the sensing capability open function network element, it initiates a location information query request to the SRF network element. This location information query request carries the sensing request area information of the internal network element, and the SRF network element responds to this location information query request by performing network-side location information mapping. When any UE initiates a sensing service request, the access and mobility management function network element to which the UE belongs will initiate a location information query request to the SRF network element. This location information query request carries the sensing request area information of the UE, and the SRF network element responds to this location information query request by performing network-side location information mapping.

[0089] Furthermore, since different network elements report corresponding sensing capability information and sensing area information to the SRF network element when reporting sensing capabilities, the sensing capability information includes at least one of the following: sensing base station information, sensing cell information, tracking area identifier, province / region information, supported sensing services, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information. Among these, sensing cell information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information are optional reporting information. When reporting sensing capabilities via access and mobility management (MLM) network elements, the information of the sensing access and mobility management (MLM) network elements to which the sensing base station belongs is the information of all MLM network elements responsible for sensing services, or the information of the MLM nodes passed through in this report; the information of the sensing network elements to which the sensing base station belongs is the information of all sensing network elements statically configured to which the sensing base station belongs, or the information of the sensing nodes passed through in this report; the information of the sensing control plane network elements to which the sensing base station belongs is the information of all sensing control plane network elements statically configured to which the sensing base station belongs, or the information of the sensing control plane network elements passed through in this report. When reporting sensing capabilities without access and mobility management (MLM) network elements, the information of the sensing network elements to which the sensing base station belongs is the information of all sensing network elements statically configured to which the sensing base station belongs, or the information of the sensing nodes passed through in this report; the information of the sensing control plane network elements to which the sensing base station belongs is the information of all sensing control plane network elements statically configured to which the sensing base station belongs, or the information of the sensing control plane network elements passed through in this report. Therefore, when receiving the sensing request area information carried in the location information query request, it is possible to query the corresponding sensing area information from the stored data and determine at least one of the following in the corresponding sensing capability information: sensing base station information, sensing cell information, tracking area identifier, province / region information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information, so as to realize the mapping of network-side location information. That is, the network-side location information includes at least one of the following: sensing base station information, sensing cell information, tracking area identifier, province / region information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information.

[0090] As an optional solution, the sensing storage function network element is also used to determine the sensing node information corresponding to the type of sensing service carried in the location information query request based on the stored sensing capability information of each of the sensing regions; and to determine the network-side location information matching the sensing request region information and the sensing node information based on the sensing capability information corresponding to the stored sensing region information, and to feed it back to the query requesting party that sent the location information query request.

[0091] It is worth noting that since the sensing capability information reported by different network elements contains the sensing services they support, and the types of sensing services supported by different network elements in the same sensing area may differ, in order to further improve the reliability of sensing service processing, the sensing storage function network element in this embodiment is also used to determine the sensing node information corresponding to the type of sensing service carried in the location information query request based on the stored sensing capability information, so as to clearly identify the network-side location information that matches both the current sensing request area information and the sensing node information.

[0092] Furthermore, considering that the sensing request area may involve multiple sets of access and mobility management functions (AMUs) and sensing nodes / sensing control plane function nodes, the results returned by the SRF node can be provided as an index if there is no AMU or sensing network element / sensing control plane function information. If there is AMU or sensing network element / sensing control plane function information, it can be provided as an index. An example of reference information using TAI as an index is shown in Table 1 below:

[0093] Table 1 provides reference information indexed by TAI.

[0094] As an optional solution, sending a second sensing request to the target sensing base station based on the network-side location information specifically includes:

[0095] Based on the sensing base station information in the network-side location information, determine the target sensing base station corresponding to the sensing base station information;

[0096] The second sensing request may be sent directly to the target sensing base station; or, the second sensing request may be sent to the target access and mobility management function (MAC) network element to instruct the MAC network element to send the second sensing request to the target sensing base station; wherein the target MAC network element is discovered by the network repository function network element based on the sensing request area information, the network-side location information and / or sensing capability support parameters, or determined based on preset MAC network element configuration information.

[0097] It's worth noting that sensor network architectures can be categorized into two types: tightly coupled and loosely coupled. Currently, the tightly coupled architecture in the IMT2020 standard requires communication through the core network, including wireless sensing base stations interconnecting with sensing network elements / sensing control plane function network elements via access and mobility management function network elements. In contrast, the loosely coupled architecture does not involve the core network, allowing wireless sensing base stations to directly interconnect with sensing network elements / sensing control plane function network elements without going through access and mobility management function network elements. If, during actual deployment, there are simultaneous needs for both tightly coupled and loosely coupled interfaces within the same sensing area, or if sensing base stations require adjustments between the two architectures, the sensing base stations must support both interfaces simultaneously. To simplify the interface requirements of wireless base stations, this embodiment provides a tightly coupled architecture for collaboration with the core network during the sensing service process, where the sensing base station and sensing network elements / sensing control plane functional network elements can be connected via access and mobility management function network elements or without access and mobility management function network elements. In actual deployment, one method can be selected based on network requirements. Figure 2 shows a system architecture diagram of an optional embodiment of the sensing service processing method without access and mobility management function network elements provided in this disclosure, and Figure 3 shows a system architecture diagram of an optional embodiment of the sensing service processing method with access and mobility management function network elements provided in this disclosure. In this context, UE stands for User Equipment, RAN for Radio Access Network, UPF for User Plane Function, AMF for Access and Mobility Management Function, UDM (Unified Data Management) for Unified Data Management, UDR (Unified Data Repository) for Unified Data Repository, NRF (Network Repository Function) for Network Repository Function, NEF (Network Exposure Function) for Network Exposure Function, SF for Sensing Function, SF-C (Sensing Function-Control plane) for Sensing Control Plane Function, SF-U (Sensing Function-User plane) for Sensing User Plane Function, PCF (Policy Control Function) for Policy Control Function, and AF (Application Function) for Application Function.

[0098] As shown in Figure 4, taking the application function network element initiating a sensing service request as an example, in the mode without going through the access and mobility management function network elements, the application function network element initiates a sensing service request to the sensing capability opening function network element, including the sensing service type, service requirements, sensing request area information (such as the latitude and longitude information, grid, three-dimensional coordinate information, etc. of the geographical area), the Internet Protocol Address / Identifier (IP / ID) of the application function network element, and the sensing service identifier (ID), etc.; the sensing capability opening function network element performs sensing request authentication on the application function network element, including whether it is allowed to use the network's sensing capabilities, sensing service type, area, time / moment, and quality of service. Service (QoS) metrics, etc.; the sensing capability open function network element queries the SRF node for the network-side location information corresponding to the sensing request area (such as latitude and longitude), and the sensing node information corresponding to the sensing service type, such as the sensing base station information, sensing cell information (optional), province / region information (optional), TAI, sensing area information (such as grid), access and mobility management function (optional), and sensing node / sensing control plane function node information (optional) corresponding to the sensing request area and / or sensing service type; the sensing capability open function network element discovers sensing nodes / sensing control plane function nodes based on the obtained province / region information, TAI, sensing area information, or sensing network element / sensing control plane function network element information, sensing service type, etc., and sends a sensing request, while carrying the sensing base station, sensing cell information (optional), TAI, and sensing request area information (such as grid, latitude and longitude) corresponding to the sensing request area. The system includes information such as the degree of perception, the storage node information for the perception results (optional), the IP / ID of the application function network element (optional), and the perception service ID. The storage node information for the perception results is used in scenarios where the perception results need to be stored uniformly, and the storage node information for the perception results can be an SRF node. In this embodiment, after receiving the first perception request sent by the perception capability open function network element, a second perception request is sent to the corresponding target perception base station based on the perception base station information therein. At the same time, the second perception request carries the perception base station information, perception cell information (optional), perception request area information (such as grid, latitude and longitude, etc.), and the corresponding data reporting perception node / perception user plane function node, the IP / ID of the application function network element (optional), and the perception service ID information. The target perception base station responds to the perception request and completes the perception detection and perception data acquisition. Then, it reports the perception data to the perception user plane function / perception node received in the second perception request. Thus, this embodiment can receive the perception data fed back by the target perception base station.

The reporting sensing result storage node information is used in scenarios where sensing results need to be uniformly stored, and the sensing result storage node information can be an SRF node. In this embodiment, after receiving the first sensing request sent by the sensing capability opening function network element, the network storage function network element, based on the sensing request area information and the network... The network-side location information and / or sensing capability support parameters, such as the province / region information, TAI, sensing area information, access and mobility management function information, are used for service discovery to determine the target access and mobility management function network element, or to determine the target access and mobility management function network element based on the preset access and mobility management function network element configuration information, and to send a second sensing request, which carries sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude, three-dimensional coordinate information, etc.), and the corresponding data reporting sensing node / sensing user plane function node, application function network element IP / ID (optional), sensing service ID information, etc.The target access and mobility management function (MIM) network element sends a sensing request to the corresponding target sensing base station based on the received second sensing request. This request carries sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude), and the IP / ID (optional) of the corresponding data reporting sensing node / sensing user plane function node, application function network element, and sensing service ID information. The target sensing base station responds to the sensing request through the target MMI network element, completes sensing detection and sensing data acquisition, and then reports the sensing data to the sensing user plane function / sensing node received in the second sensing request. Thus, this embodiment is able to receive the sensing data fed back by the target sensing base station.

[0100] As shown in Figure 6, taking a UE initiating a sensing service request as an example, in the mode without going through the access and mobility management function (AM) network element, the UE initiates a sensing request to its affiliated AM network element via the base station. This request includes the sensing service type, service requirements, sensing request area information (such as latitude and longitude of the geographical area), UE information, and sensing service ID. The AM network element then performs sensing service authentication with the UE's affiliated unified data management device / unified data storage device, including whether the UE is allowed to use the network's sensing capabilities, sensing service type, area, time / slot, QoS indicators, etc. The UE's affiliated AM network element then performs sensing service authentication with the UE's affiliated unified data management device / unified data storage device. The network element obtains network-side location information (such as latitude and longitude, grid, 3D coordinate information, etc.) corresponding to the sensing request area from the SRF node to which the sensing area belongs, as well as sensing node information corresponding to the sensing service type, such as sensing base station information, sensing cell information (optional), province / region information (optional), TAI, sensing area information (such as grid, etc.), access and mobility management function (optional), sensing node / sensing control plane function node information (optional), and storage node information for reported sensing results (optional), etc., corresponding to the sensing request area and / or sensing service type.

In this embodiment, after receiving the first sensing request sent by the access and mobility management function network element, based on... The sensing base station sends a second sensing request to the corresponding target sensing base station, carrying sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude, three-dimensional coordinate information, etc.), and corresponding data reporting sensing node / sensing user plane function node, UE information (optional), sensing service ID information, etc.; the target sensing base station responds to the sensing request, completes sensing detection and sensing data acquisition, and then reports the sensing data to the sensing user plane function / sensing node received in the second sensing request, so that this embodiment can receive the sensing data fed back by the target sensing base station.

[0101] As shown in Figure 7, taking the UE initiating a sensing service request as an example, in the method via the access and mobility management function (AMF) network element, the UE initiates a sensing request to its AMF network element via the base station, including the sensing service type, service requirements, sensing request area information (such as the latitude and longitude information, grid, 3D coordinate information, etc. of the geographical area), UE information, sensing service ID, etc.; the AMF network element performs sensing service authentication with the unified data management device / unified data storage device to which the UE belongs, including whether the UE is allowed to use the network's sensing capabilities, sensing service type, area, time / moment, QoS indicators, etc.; the AMF network element to which the UE belongs obtains the sensing request area (such as via the SRF node to which the sensing area belongs) from the SRF node to which the sensing area belongs. Network-side location information (such as latitude, grid, and 3D coordinate information) and sensing node information corresponding to sensing service types, such as sensing base station information, sensing cell information (optional), province / region information (optional), TAI, sensing area information (such as grid), access and mobility management function (optional), sensing node / sensing control plane function node information (optional), and storage node information for reported sensing results (optional) corresponding to the sensing request area and / or sensing service type. The UE's access and mobility management function network element discovers sensing nodes / sensing control plane function nodes based on the acquired province / region information, TAI, sensing area information, sensing network element / sensing control plane function network element information, and sensing service type. The system sends a perception request to the access and mobility management function (AMI) network element, carrying the perception base station, perception cell information (optional), TAI (Target Area Identity), perception request area information (such as grid, latitude and longitude), storage node information for reported perception results (optional), UE information (optional), and perception service ID, etc., corresponding to the perception request area. In this embodiment, after receiving the first perception request from the AMI network element, the system performs service discovery through the network storage function network element based on the perception request area information, the network-side location information, and / or perception capability support parameters, such as province / region information, TAI, perception area information, and AMI information, to determine the target AMI network element, or based on a preset AMI network element. The target access and mobility management function network element is determined by configuring the network element configuration information, and a second sensing request is sent, carrying sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude, etc.), and corresponding data reporting sensing node / sensing user plane function node, UE information (optional), sensing service ID information, etc.; the target access and mobility management function network element sends a sensing request to the corresponding target sensing base station based on the received second sensing request, also carrying sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude, etc.), and corresponding data reporting sensing node / sensing user plane function node, UE information (optional), sensing service ID information, etc.The target sensing base station responds to the sensing request through the target access and mobility management function network element, completes sensing detection and sensing data acquisition, and then reports the sensing data to the sensing user plane function / sensing node received in the second sensing request. Thus, this embodiment is able to receive the sensing data fed back by the target sensing base station.

[0102] It is worth noting that, in order to adapt to the sensing service processing flow for wireless sensing scenarios, the access and mobility management function network element in this embodiment, when registering with the network repository function network element, in addition to the basic parameters defined by the standard, registers with the network repository function based on the service area (such as TAI, province / region information, sensing area information (optional)). Among them, "sensing area information" is a new parameter and is optional. At the same time, the access and mobility management function network element can optionally add whether to register to support sensing capabilities. Therefore, the way to discover access and mobility management function network elements in this embodiment includes: (1) discovery based on the sensing request area information, the network side location information and / or sensing capability support parameters, etc.; (2) determination based on the preset configuration information of the access and mobility management function network element. If the access and mobility management function network element adopts a disaster recovery mode, such as a group resource pool (POOL) or 1+1 disaster recovery mode, the surrounding network elements should support the configuration of all access and mobility management function node data of the belonging network element for mutual disaster recovery and support disaster recovery failover. In addition, for scenarios where the UE initiates a perception request, the access and mobility management function can also be selected in the following ways: based on the existing N2 interface, the perception service process can be initiated through the access and mobility management function network element to which the N2 interface currently registered by the UE belongs.

[0103] As an optional solution, receiving the sensing data sent by the target sensing base station specifically includes:

[0104] The sensing data can be received directly from the target sensing base station; or, the sensing data sent by the target sensing base station can be received through a sensing user plane function network element. The sensing user plane function network element is determined based on the sensing service type and the sensing request area information, whereby the sensing service type is obtained from the first sensing request. It is worth noting that if the current network architecture is not a C / U separation architecture, the sensing data is received directly from the target sensing base station; if the current network architecture is a C / U separation architecture, a sensing user plane function network element needs to be selected first based on the sensing service type and sensing request area information using predetermined rules, and then this sensing user plane function network element receives the sensing data sent by the target sensing base station.

[0105] As an optional solution, after receiving the sensing data sent by the target sensing base station, the method further includes:

[0106] The sensed data is processed to obtain a sensed result; the sensed result is reported to the sensed requester or the sensed capability open function network element that sent the first sensed request; or, the sensed result is reported to the sensed requester or the sensed capability open function network element that sent the first sensed request through the sensed user plane function network element.

[0107] It is worth noting that, for the sensing data received from the target sensing base station, this embodiment requires further computational processing to obtain the information features of the target object or target area (e.g., the size and speed of the target object, the humidity and air quality of the target area) to obtain the sensing results required by the sensing requester. For non-C / U separation architectures, the processed sensing results are directly reported to the sensing requester (e.g., UE, network internal element, application function element) or the sensing capability open function element that sent the first sensing request, and the sensing capability open function element feeds back the sensing results to the sensing requester (e.g., application function element, network internal element). For C / U separation architectures, the sensing results need to be reported to the sensing requester or the sensing capability open function element that sent the first sensing request by the sensing user plane function element.

[0108] As an optional solution, after receiving the first sensing request, the method further includes:

[0109] Send a sensing service control policy request to the target policy control function network element; wherein, the sensing service control policy request is used to instruct the target policy control function network element to send a sensing service control policy; the target policy control function network element is discovered by the network repository function network element based on the network-side location information and / or sensing capability support parameters, or determined based on preset configuration information of the policy control function network element to which it belongs;

[0110] The system receives the sensing service control policy sent by the target policy control function network element and executes the sensing service control policy during the processing of the sensing service.

[0111] It is worth noting that the policy control function network element is a node that safeguards the sensing service and determines whether to provide high-priority protection for a specific sensing service reported to the network side. It can be understood that, upon receiving a sensing request for the current sensing service, this embodiment will obtain the sensing service control policy from the target policy control function network element discovered based on service discovery methods or static configuration, and execute the relevant protection policy in subsequent sensing service processes and data reporting. For example, this policy includes guarantees for service priority, transmission bandwidth, transmission latency, etc.

[0112] As an optional solution, the method further includes:

[0113] The sensing result is reported to the sensing storage function network element; or, the sensing result is reported to the sensing storage function network element through the sensing user plane function network element; wherein, the sensing storage function network element is also used to store the sensing result; the sensing storage function network element is discovered by the network storage repository function network element based on the basic parameters of the sensing storage function network element, the network-side location information and / or sensing capability support parameters, or determined based on the preset configuration information of the sensing storage function network element to which it belongs.

[0114] Specifically, in this embodiment, the methods for discovering sensing storage function network elements include static configuration and service discovery. For static configuration, the sensing storage function network element to be reported can be directly determined based on the pre-configured address information of its parent sensing storage function network element. For service discovery, since the sensing storage function network element has registered with the network storage function network element, it can send a sensing storage service discovery request message to the network storage function network element. This request message includes the required basic parameters of the sensing storage function network element, the network-side location information, and / or sensing capability support parameters, such as network element type, network function identifier, and target service area, to instruct the network storage function network element to query the corresponding sensing storage function network element. Then, based on the query results carried in the response message from the network storage function network element, the sensing storage function network element to be reported is determined.

[0115] As an optional solution, the sensing storage function network element is also used to send a sensing storage service registration request to the network storage function network element; wherein, the sensing storage service registration request includes at least one of the preset sensing storage function network element basic parameters, service area information, and sensing capability support parameters.

[0116] Specifically, since the sensing storage function network element in this embodiment is a newly added node, it needs to register with the network storage function network element. This involves sending a sensing storage service registration request to the network storage function network element. The basic parameters of the sensing storage function network element include network function parameter information such as the standard-defined network function profile / network element profile (NF profile), network function service / network element service (NF service), and network function information / network element information (NF info). The sensing storage service registration request may also include supported service area information, such as the service scope (which can be province / region information, etc.), the tracking area identifier list (TAI List), the tracking area identifier range list (TAI Range List), and sensing capability support information parameters, etc. These will not be elaborated further in this embodiment. As a newly added node, the sensing storage function network element in this embodiment can be named as a new NF type, i.e., named the sensing storage function network element.

[0117] Please refer to Figure 8. A second aspect of this disclosure provides a method for processing perceived services, including the following steps S21 to S23:

[0118] Step S21: Receive a first sensing request; wherein the first sensing request is used to initiate a sensing service, and the first sensing request includes sensing request area information and its corresponding network-side location information; the network-side location information is obtained by the sensing capability open function network element based on the sensing request area information and / or the type of the sensing service;

[0119] Step S22: Send a second sensing request to the target sensing base station based on the network-side location information; wherein, the second sensing request is used to instruct the target sensing base station to start a sensing task;

[0120] Step S23: Receive sensing data sent by the target sensing base station.

[0121] Specifically, the perception service processing method provided in this embodiment is also executed by perception network elements or perception control plane function network elements, thereby meeting the perception service processing requirements under different deployment architectures. In order to complete the mapping from perception geographical / administrative regions to network-side location information for network element discovery and other needs, this embodiment utilizes perception capability open function network elements to obtain corresponding network-side location information based on the perception request area information of perception requesting parties such as application function network elements, network internal network elements, and UEs. Specifically, after receiving a first perception request, this embodiment first initiates a perception service in response to the first perception request. Based on the network-side location information carried in the first perception request, the target perception base station to be performed can be identified, and a second perception request is sent to the target perception base station. It is worth noting that the second perception request includes the perception request area information and its corresponding network-side location information, as well as the corresponding data reporting perception network element / perception user plane function network element information, perception requesting party information (optional), and perception service identification information; wherein, the perception requesting party information and the perception service identification information are sent together by the perception requesting party when initiating the perception service request. The second sensing request instructs the target sensing base station to initiate a sensing task, namely, to complete sensing detection and sensing data acquisition, and then receive sensing data fed back by the target sensing base station.

[0122] As an optional solution, receiving the first sensing request specifically includes:

[0123] The system can receive a first sensing request from any application function network element or network internal network element, or directly from any network internal network element, or from any user equipment (UE) via the access and mobility management (AML) network element. It is worth noting that sensing service requests initiated by application function network elements require the first sensing request to be sent via the sensing capability open function network element. If the sensing service request is initiated by a network internal network element, the type and requirements of the initiating network element determine whether it needs to go through the sensing capability open function network element. If it does not need to go through the sensing capability open function network element, the network internal network element can directly send the first sensing request after receiving the network-side location information fed back by the sensing capability open function network element. For the UE, it first needs to initiate a sensing service request to its affiliated access and mobility management (AML) network element via the base station, and then the AML network element sends the first sensing request after receiving the network-side location information fed back by the sensing capability open function network element.

[0124] As an optional solution, the sensing capability open function network element is used to store sensing capability information and sensing area information of different network elements; when receiving a sensing service request or a location information query request, based on the sensing capability information corresponding to each of the stored sensing area information, the sensing request area information carried in the sensing service request or the sensing request area information carried in the location information query request is mapped to the corresponding network-side location information, and fed back to the sensing requester that sent the sensing service request or the query requester that sent the location information query request; wherein, the query requester is the access and mobility management function network element or the network internal network element; the sensing capability information includes at least one of sensing base station information, sensing cell information, tracking area identifier, province / region information, supported sensing services, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information.

[0125] Specifically, in order to facilitate unified management and retrieval of data, the sensing capability open function network element in this embodiment is used to uniformly store sensing capability information and sensing area information, and convert the stored sensing capability information and sensing area information into structured data according to a preset format, supporting unified retrieval by other surrounding nodes. Understandably, when any application function network element or internal network element initiates a sensing service request to the sensing capability open function network element, the sensing capability open function network element performs network-side location information mapping based on the sensing request area information carried in the received sensing service request; when any internal network element does not need to initiate a sensing service through the sensing capability open function network element, it initiates a location information query request to the sensing capability open function network element, which carries the sensing request area information of the internal network element, and thus the sensing capability open function network element responds to the location information query request by performing network-side location information mapping; when any UE initiates a sensing service request, the access and mobility management function network element to which the UE belongs will initiate a location information query request to the sensing capability open function network element, which carries the sensing request area information of the UE, and thus the sensing capability open function network element responds to the location information query request by performing network-side location information mapping.

[0126] Furthermore, when different network elements report their sensing capabilities, they will report corresponding sensing capability information and sensing area information to the sensing capability opening function network element. The sensing capability information includes at least one of the following: sensing base station information, sensing cell information, tracking area identifier, province / region information, supported sensing services, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information. Among these, sensing cell information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information are optional reporting information. When reporting sensing capabilities via access and mobility management (MLM) network elements, the information of the sensing access and mobility management (MLM) network elements to which the sensing base station belongs is the information of all MLM network elements responsible for sensing services, or the information of the MLM nodes passed through in this report; the information of the sensing network elements to which the sensing base station belongs is the information of all sensing network elements statically configured to which the sensing base station belongs, or the information of the sensing nodes passed through in this report; the information of the sensing control plane network elements to which the sensing base station belongs is the information of all sensing control plane network elements statically configured to which the sensing base station belongs, or the information of the sensing control plane network elements passed through in this report. When reporting sensing capabilities without access and mobility management (MLM) network elements, the information of the sensing network elements to which the sensing base station belongs is the information of all sensing network elements statically configured to which the sensing base station belongs, or the information of the sensing nodes passed through in this report; the information of the sensing control plane network elements to which the sensing base station belongs is the information of all sensing control plane network elements statically configured to which the sensing base station belongs, or the information of the sensing control plane network elements passed through in this report. Therefore, when receiving sensing request area information carried in a sensing service request or a location information query request, the system can query the corresponding sensing area information from the stored data and determine at least one of the following in the corresponding sensing capability information: sensing base station information, sensing cell information, tracking area identifier, province / region information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information. This enables the mapping of network-side location information, which includes at least one of the following: sensing base station information, sensing cell information, tracking area identifier, province / region information, sensing access and mobility management function network element information, sensing network element information, and sensing control plane function network element information.

[0127] As an optional solution, the sensing capability open function network element is also used to determine the sensing node information corresponding to the type of sensing service carried in the sensing service request or the type of sensing service carried in the location information query request based on the stored sensing capability information of each sensing area; and to determine the network-side location information matching the sensing request area information and the sensing node information based on the stored sensing capability information of each sensing area information, and to feed it back to the query requesting party that sent the location information query request.

[0128] It is worth noting that since the sensing capability information reported by different network elements contains the sensing services they support, and the types of sensing services supported by different network elements in the same sensing area may differ, in order to further improve the reliability of sensing service processing, the sensing capability opening function network element in this embodiment is also used to determine the sensing node information corresponding to the type of sensing service carried by the currently received sensing service request or location information query request based on the stored sensing capability information, so as to clearly identify the network-side location information that matches both the current sensing request area information and the sensing node information.

[0129] Furthermore, considering that the sensing request area may involve multiple sets of access and mobility management functions and sensing node / sensing control plane function nodes, the results returned by the sensing capability open function node can be provided as an index if there is no access and mobility management function or sensing network element / sensing control plane function network element information; if there is access and mobility management function or sensing network element / sensing control plane function network element information, the access and mobility management function (optional) or sensing network element / sensing control plane function network element (optional) information can be provided as an index.

[0130] As an optional solution, sending a second sensing request to the target sensing base station based on the network-side location information specifically includes:

[0131] Based on the sensing base station information in the network-side location information, determine the target sensing base station corresponding to the sensing base station information;

[0132] The second sensing request may be sent directly to the target sensing base station; or, the second sensing request may be sent to the target access and mobility management function (MAC) network element to instruct the MAC network element to send the second sensing request to the target sensing base station; wherein the target MAC network element is discovered by the network repository function network element based on the sensing request area information, the network-side location information and / or sensing capability support parameters, or determined based on preset MAC network element configuration information.

[0133] It's worth noting that sensor network architectures can be categorized into two types: tightly coupled and loosely coupled. Currently, the tightly coupled architecture in the IMT2020 standard requires communication through the core network, including wireless sensing base stations interconnecting with sensing network elements / sensing control plane function network elements via access and mobility management function network elements. In contrast, the loosely coupled architecture does not involve the core network, allowing wireless sensing base stations to directly interconnect with sensing network elements / sensing control plane function network elements without going through access and mobility management function network elements. If, during actual deployment, there are simultaneous needs for both tightly coupled and loosely coupled interfaces within the same sensing area, or if sensing base stations require adjustments between the two architectures, the sensing base stations must support both interfaces simultaneously. To simplify the interface requirements of wireless base stations, this embodiment provides a tightly coupled architecture for collaboration with the core network during the sensing service process, where the sensing base station and sensing network elements / sensing control plane functional network elements can be connected via access and mobility management function network elements or without access and mobility management function network elements. In actual deployment, one method can be selected based on network requirements. Figure 9 shows a system architecture diagram of another optional embodiment of the sensing service processing method without access and mobility management function network elements provided in this disclosure, and Figure 10 shows a system architecture diagram of another optional embodiment of the sensing service processing method with access and mobility management function network elements provided in this disclosure.

[0134] As shown in Figure 11, taking the application function network element initiating a sensing service request as an example, in the mode without going through the access and mobility management function network elements, the application function network element initiates a sensing service request to the sensing capability opening function network element, including the sensing service type, service requirements, sensing request area information (such as the latitude and longitude information, grid, 3D coordinate information, etc. of the geographical area), the IP / ID of the application function network element, the sensing service ID, etc.; the sensing capability opening function network element performs sensing request authentication on the application function network element, including whether it is allowed to use the network's sensing capabilities, sensing service type, area, time / moment, QoS indicators, etc.; the sensing capability opening function network element locally completes the sensing request area (such as Mapping of latitude and longitude, grid, and 3D coordinate information to corresponding network-side location information, and specifying the sensing node information corresponding to the sensing service type, such as sensing base station information, sensing cell information (optional), province / region information (optional), TAI, sensing area information (such as latitude and longitude, grid, and 3D coordinate information), access and mobility management functions (optional), and sensing node / sensing control plane function node information (optional) corresponding to the sensing request area and / or sensing service type; sensing capability opening function network elements are based on the obtained sensing request area's corresponding province / region information, TAI, sensing area information, or sensing network element / sensing control plane function node information. The system detects sensing nodes / sensing control plane functional nodes by sensing control plane network element information, sensing service type, etc., and sends a sensing request. This request includes the sensing base station corresponding to the sensing request area, sensing cell information (optional), the associated TAI, sensing request area information (such as grid, latitude and longitude, 3D coordinate information, etc.), information on the storage node for reported sensing results (optional), the IP / ID of the application functional network element (optional), and the sensing service ID. The information on the storage node for reported sensing results is used in scenarios where sensing results need to be stored uniformly. This storage node can be a sensing capability open functional node or other nodes. In this embodiment, upon receiving the request from the sensing capability open functional network element... After the first sensing request, a second sensing request is sent to the corresponding target sensing base station based on the sensing base station information therein. The second sensing request carries sensing base station information, sensing cell information (optional), sensing request area information (such as grid, latitude and longitude, three-dimensional coordinate information, etc.), and corresponding data reporting sensing node / sensing user plane function node, application function network element IP / ID (optional), sensing service ID information, etc. The target sensing base station responds to the sensing request, completes sensing detection and sensing data acquisition, and then reports the sensing data to the sensing user plane function / sensing node received in the second sensing request. Thus, this embodiment can receive the sensing data fed back by the target sensing base station.

[0135] As shown in Figure 12, taking the application function network element initiating a sensing service request as an example, in the method of passing through the access and mobility management function network elements, the application function network element initiates a sensing service request to the sensing capability opening function network element, including the sensing service type, service requirements, sensing request area information (such as the latitude and longitude information, grid, 3D coordinate information, etc. of the geographical area), the IP / ID of the application function network element, and the sensing service ID, etc.; the sensing capability opening function network element performs sensing request authentication on the application function network element, including whether it is allowed to use the network's sensing capabilities, sensing service type, area, time / moment, QoS indicators, etc.; the sensing capability opening function network element locally completes the sensing request area (such as latitude and longitude, grid, etc.). The mapping of three-dimensional coordinate information to the corresponding network-side location information, and the explicit perception node information corresponding to the perception service type, such as the perception base station information, perception cell information (optional), province / region information (optional), TAI, perception area information (such as grid), access and mobility management function (optional), perception node / perception control plane function node information (optional), etc., corresponding to the perception request area and / or perception service type; the perception capability opening function network element discovers perception based on the province / region information, TAI, perception area information, or perception network element / perception control plane function network element information, perception service type, etc., corresponding to the obtained perception request area. The node / sensing control plane functional node sends a sensing request, carrying the sensing base station, sensing cell information (optional), belonging TAI, sensing request area information (such as grid, latitude and longitude, 3D coordinate information, etc.), sensing result storage node information (optional), application function network element IP / ID (optional), sensing service ID, etc., corresponding to the sensing request area. The sensing result storage node information is used in scenarios where sensing results need to be uniformly stored. The sensing result storage node information can be a sensing capability opening functional node or other nodes. In this embodiment, after receiving the first sensing request sent by the sensing capability opening functional network element, the network storage function network element, based on the sensing request... Service discovery is performed using regional information, network-side location information, and / or sensing capability support parameters, such as province / region information, TAI, sensing area information, and access and mobility management function information. The target access and mobility management function network element is determined, or the target access and mobility management function network element is determined based on the preset configuration information of the access and mobility management function network element.

Thus, this embodiment is able to receive the sensing data fed back by the target sensing base station.

[0137] As shown in Figure 14, taking the UE initiating a sensing service request as an example, in the method via the access and mobility management function (AMU) network element, the UE initiates a sensing request to its AMU via the base station, including the sensing service type, service requirements, sensing request area information (such as latitude and longitude information, grid, 3D coordinate information, etc. of the geographical area), UE information, sensing service ID, etc.; the AMU performs sensing service authentication with the unified data management device / unified data storage device to which the UE belongs, including whether the UE is allowed to use the network's sensing capabilities, sensing service type, area, time / slot, QoS indicators, etc.; the UE's AMU performs sensing service authentication with the unified data management device / unified data storage device to which the UE belongs, including whether the UE is allowed to use the network's sensing capabilities, sensing service type, area, time / slot, QoS indicators, etc.; the UE's access and mobility management device... The functional network element obtains network-side location information (such as latitude and longitude, grid, 3D coordinate information, etc.) corresponding to the sensing request area from the sensing capability open functional nodes of the sensing area, as well as sensing node information corresponding to the sensing service type, such as sensing base station information, sensing cell information (optional), province / region information (optional), TAI, sensing area information (such as grid, etc.), access and mobility management function (optional), sensing node / sensing control plane functional node information (optional), and storage node information for reported sensing results (optional) corresponding to the sensing request area and / or sensing service type; the access and mobility management function network element of the UE is based on The system acquires province / region information, its associated TAI, perception area information, perception network element / perception control plane functional network element information, perception service type, etc., to discover perception nodes / perception control plane functional nodes, and sends a perception request.

Thus, this embodiment can receive the sensing data fed back by the target sensing base station.

[0138] As an optional solution, receiving the sensing data sent by the target sensing base station specifically includes:

[0139] The sensing data can be received directly from the target sensing base station; or, the sensing data sent by the target sensing base station can be received through a sensing user plane function network element. The sensing user plane function network element is determined based on the sensing service type and the sensing request area information, whereby the sensing service type is obtained from the first sensing request. It is worth noting that if the current network architecture is not a C / U separation architecture, the sensing data is received directly from the target sensing base station; if the current network architecture is a C / U separation architecture, a sensing user plane function network element needs to be selected first based on the sensing service type and sensing request area information using predetermined rules, and then this sensing user plane function network element receives the sensing data sent by the target sensing base station.

[0140] As an optional solution, after receiving the sensing data sent by the target sensing base station, the method further includes:

[0141] The perceived data is processed to obtain the perceived results;

[0142] The sensing results are reported to the sensing requester or the sensing capability open function network element that sends the first sensing request; or, the sensing user plane function network element reports the sensing results to the sensing requester or the sensing capability open function network element that sends the first sensing request.

[0143] It is worth noting that, for the sensing data received from the target sensing base station, this embodiment requires further computational processing to obtain the information features of the target object or target area, in order to obtain the sensing result required by the sensing requester. For non-C / U separation architectures, the processed sensing result is directly reported to the sensing requester (such as UE, network internal network element, application function network element) or the sensing capability open function network element that sent the first sensing request, and the sensing capability open function network element feeds back the sensing result to the sensing requester (such as application function network element, network internal network element). For C / U separation architectures, the sensing result needs to be reported to the sensing requester or the sensing capability open function network element that sent the first sensing request by the sensing user plane function network element.

[0144] As an optional solution, after receiving the first sensing request, the method further includes:

[0145] Send a sensing service control policy request to the target policy control function network element; wherein, the sensing service control policy request is used to instruct the target policy control function network element to send a sensing service control policy; the target policy control function network element is discovered by the network repository function network element based on the network-side location information and / or sensing capability support parameters, or determined based on preset configuration information of the policy control function network element to which it belongs;

[0146] The system receives the sensing service control policy sent by the target policy control function network element and executes the sensing service control policy during the processing of the sensing service.

[0147] It is worth noting that the policy control function network element is a node that safeguards the sensing service and determines whether to provide high-priority protection for a specific sensing service reported to the network side. It can be understood that, upon receiving a sensing request for the current sensing service, this embodiment will obtain the sensing service control policy from the target policy control function network element discovered based on service discovery methods or static configuration, and execute the relevant protection policy in subsequent sensing service processes and data reporting. For example, this policy includes guarantees for service priority, transmission bandwidth, transmission latency, etc.

[0148] As an optional solution, the method further includes:

[0149] When the sensing result is not reported to the sensing capability open function network element, the sensing result is reported to the sensing capability open function network element; or, when the sensing result is not reported to the sensing capability open function network element, the sensing result is reported to the sensing capability open function network element through the sensing user plane function network element; wherein, the sensing capability open function network element is also used to store the sensing result; the sensing capability open function network element is discovered by the network storage function network element based on the basic parameters of the sensing capability open function network element, the network-side location information and / or sensing capability support parameters, or determined based on the preset configuration information of the sensing capability open function network element to which it belongs.

[0150] It is worth noting that when the first sensing request is initially received by a sensing capability open function network element, the sensing result needs to be sent back to the sensing requester via the sensing capability open function network element. In this case, the sensing capability open function network element can simultaneously store the sensing result. When the first sensing request is not initially received by a sensing capability open function network element, the sensing result is not simultaneously reported to the sensing capability open function network element when it is fed back to the sensing requester. In this case, this embodiment can further report the sensing result to the sensing capability open function network element, which will uniformly store the sensing result of each sensing service processing.

[0151] Specifically, in this embodiment, the methods for discovering the sensing capability open function network element include static configuration and service discovery. For static configuration, the sensing capability open function network element to be reported can be directly determined based on the pre-configured address information of its parent sensing capability open function network element. For service discovery, since the sensing capability open function network element has registered with the network repository function network element, it can send a sensing capability open function network element discovery request message to the network repository function network element. This request message includes the required basic parameters of the sensing capability open function network element, the network-side location information, and / or sensing capability support parameters, such as TAI, province / region information, etc., to instruct the network repository function network element to query the corresponding sensing capability open function network element. Then, based on the query results carried in the response message returned by the network repository function network element, the sensing capability open function network element to be reported is determined.

[0152] It is worth noting that in this embodiment, the way the surrounding nodes discover the sensing network element / sensing control plane functional network element is as follows: (1) The discovery method based on the service interface, that is, the sensing network element / sensing control plane functional network element is registered to the network storage function network element. The surrounding network element and the sensing network element / sensing control plane functional network element support service discovery. The sensing network element / sensing control plane functional network element can be discovered based on the basic parameters of the sensing network element / sensing control plane functional network element, the network side location information and / or sensing service type, such as TAI, province / region information, etc. (2) The surrounding network element is statically configured with its own sensing network element / sensing control plane functional network element. If the own sensing network element / sensing control plane functional network element is deployed in a disaster recovery mode, such as group POOL or 1+1 disaster recovery mode, the surrounding network element should support the configuration of all its own sensing nodes / sensing control plane functional nodes that are mutually disaster recovery, and support disaster recovery failover.

[0153] The sensing service processing method provided in this disclosure uses a sensing storage function network element to map geographic / administrative regions to network-side location information, or uses a sensing capability open function network element to map geographic / administrative regions to network-side location information. It also proposes a sensing service processing flow for wireless sensing scenarios, which can support sensing services in wireless sensing scenarios end-to-end.
